                                 INTRODUCTION

     This volume of Air Pollution Translations:  A Bibliography with Abstracts is the third in
a continuing series of compilations presenting abstracts and indexes of translations of technical
air pollution literature.  Although some entries indicate otherwise, all documents abstracted
and indexed in this volume have been translated and are available in English.

     Approximately 95 percent of the documents were translated for the Translation Services
Section, Environmental  Protection Agency, by extra-governmental contractors.  Of the
remainder, approximately 3 percent were obtained by screening published translation docu-
ments and 2 percent by screening the output of other translation services within and without the
Federal government.  Documents are translated or obtained by the Translation Services Section
only at the  request of EPA scientists.

     The entries are grouped into subject categories and arranged in numerical order using
the Air Pollution Technical Information Center (APTIC) accession number.  Subject and author
indexes refer to the abstract by category letter and APTIC accession number.  For example,
the number B-21324 refers to Section B, Control Methods, and to accession 21324 within it.
The asterisks in the author index denote the first author.

STUDIES ON  THE PREVENTION OF PUBLIC NUISANCE
BY  THE EXHAUST GASES FROM THE KRAFT PULP MILL.
(PART I. ANALYSIS OF EXHAUST GASES.) ((Tohoku J. Exp.
Med. (Tokyo))) 11 (2), 120-6 (Aug. 1964). (Presented at the 37th
Annual Meeting, Japan Society of Industrial Medicine, Kurume,
Apr. 7, 1964.)
Exhaust  gases of a Japanese kraft pulp mill were analyzed.
The reported results were as follows: In the stack gases were
contained: 0.259 g/cc of sodium sulfate, 750 ppm of hydrogen
sulfide,  196 ppm of sulfur  dioxide and organic compounds of
sulfur. The organic sulfur compounds were as follows in order
of amount: methyl mercaptan, dimethyl sulfide, isopropyl mer-
captan,  dimethyl disulfide, propyl  mercaptan or  ethyl methyl
sulfide,  diethyl sulfide and ethyl mercaptan. The amount of
dimethyl sulfide  was 8.7 ppm. Organic sulfur compounds in
the  gases in the upper part of the Jansson screen were of the
same composition as those  in the stack gases, but the arrange-
ment of the constituents in order of amount are somewhat dif-
ferent. All of these gaseous sulfur  compounds smell offensive
and characterize the exhaust gases from a  kraft  pulp mill.

HYGIENIC EVALUATION OF SOME PETROCHEMICAL IN-

Prof. Zabolevaniya  (Moscow), 10(ll):22-28, Nov. 1966. 10 refs.

Deficiencies in planning and actual operation of petrochemical
plants  are  responsible  for  the   discharge of  acetylene,
polyethylene,  phenol, acetone, methylstyrene, isoprene, divi-
nyl  and other toxic complexes which are products of decom-
position, oxidation, and hydrolysis. Desorption of toxic sub-
stances from construction materials (concrete brick) plays an
important part. The authors recommend methods for improv-
ing  working conditions in petrochemical production facilities.

WILL TRASH REMOVAL BE A MARKETING FACTOR FOR

While the removal of discarded glass containers  presents a
pro- blem, it is  not  insurmountable,  particularly if  refuse
crushing plants and techniques are developed which will refuse
the silicon from waste glass.  The  substitution  of  plastic
packaging materials for glass has the disadvantage  that during
incineration of poly- vinyl-chloride-containing material, corro-
sive gases are evolved,  which cause severe  damage  to the
boiler units of the incinerator plant. Furthermore, the emission
of hydrochloric  and  hydrofluoric  acids from  these  plastics
causes dangerous air pollution tt> such an  extent,  that in the
United States the incineration of plastic waste is forbidden in
the vicinity of large cities.

FLUORINE BALANCE AND FLUORINE  EMISSION FROM
CEMENT KILNS.  ((Flu- orhaushalt und  Fluoremission von
Zementofen.))   Text   in   German.   Zement-Kalk-Gips
(Wiesbaden), 21(1):18, Jan. 1968. 20 refs
In the burning of Portland cement  clinker, fluorine is partly
driven out of  the  raw materials  and fuel. To  determine
whether gaseous fluorine is  emitted along  with the other kiln
gases, complete fluorine determinations were performed for 11
cement kilns of varying design. No gaseous fluorides could be
detected in the cleaned gas from these kirns; the significance
of electrofilters in the  removal of solid fluorides is discussed.
In conclusion, cement kilns cannot emit  gaseous fluorides
because,  in the presence of an excess  of CaO,  they produce
CaF2. The negligible level  of fluorides in  the dust from the
cleaned gas (0.009-1.420 mg. F/Nm  to 3rd  power) is thus not
dependent upon  the magnitude of  the fluorine  balance, but
upon  the  efficiency  of  the electrostatic  precipitators.  The
amount of fluorine combined in the clinker ranges  from 88-98
percent of the total fluorine intake, and this percentage in-
creases with  a decrease in dust  load of the  emitted  gas.
Fluorine  appears  as CaF2  in clinker and  kiln  dust and, as
such, is harmless since CaF2 is relatively insoluble in water.

STUDIES OF AEROSOL CONTENT IN THE ADX IN THE
GRADUATION HOUSE ZONE IN CIECHOCINEK.  ((Badania
nad zawartoscia aerosulu w powietrzu w strefie okolotez-

A peculiarity of the Ciechocinek climate is the presence of an
atmospheric saline aerosol which might be used in inhalation
therapy.  This aerosol originates from the saline graduation
house (aerosol forming structure) which operates from spring
into the late fall and is distributed by the wind. Tests made in
1966 established the correlation between the extent of the
aerosol zone, measured as concentration of sodium ions, and
the weather. Atmospheric iodine levels were also measured, as
well as temperature, humidity, wind direction, wind velocity,
and other  meterological  conditions.  Results  were tabulated.
NaCl level, taken as an exponent of saline aerosol level, was
0.03-10.066 mg. NaCl  cu m. At higher temperatures, aerosol
particles  were concentrated due to intense water evaporation.
Atmospheric iodine  levels were 0-43.4 gamma/cu m. Compara-
tively high iodine levels were observed at low wind velocities.
Anemometric measurements for the past 30 years indicate that
western  winds prevail  in Ciechocinek.  Consequently, the
planned inhalation therapy zone should be established east of
the saline graduation house.

RAW  ENERGY SOURCES FOR ELECTRIC GENERATION.
IEEE (Inst. Elec.  Electron, Engrs) Spectrum, S(8):34-45,  Aug.
1968.
Air pollution is one  of several factors taken into consideration
in  this forecast of  the electrical energy picture  in the  USA
through 198S. Other factors include economics, fuel availabili-
ty, relative plant size,  and transportation costs. It is predicted
that the consumption of  all forms  of raw energy for electric
power generation will increase substantially during the next IS
years, probably at 3 times the rate of total energy consumption
(3.1-4.5%/yr.)- By 1985, nuclear energy will provide more than
40% of the electric power produced in the USA, and probably
more  than 70% of  that produced in New England.  Of the 4
major sources of energy currently exploited for electric power
generation: coal, gas, water, and oil (nuclear energy accounted
for only 0.4% of the total output in 1965), coal is the only one
for which the resources are  almost unlimited (900 yr. at
present rate of consumption). However, under the Air Quality
Act of 1968, coal  • or  oil-fired generating  units  'will either
have to burn the higher-cost, low-sulfur fuels or provide  some
means of reducing the SO2 content of stack gases	' '	the
simpler  SO2 removal systems, without provision for sulfur
product recovery, may require an investment of $7 to $8 per
kilowatt and result in an owning and operating cost equivalent
to a fuel  cost of 3 to 4 cents/MBtu. This will further accelerate
the trend to nuclear energy sources in  the  traditionally coal
and oil-burning areas.'

COMPARATIVE  STUDIES  OF   FLUORINE-CONTAINING
EMISSIONS.  ((Vergleichende Untersuchungen uber Fluorhal-
tige Immissionen.))  Text  in German. Stadtehygiene, 19(6):114-
115, June 1968.
Three  methods determining the presence  of fluorine  com-
pounds as phytotoxic air pollutants are under consideration:
(1) air analysis, (2)  precipitate analysis,  and (3) plant studies.
In the past, proof of damage was accepted if fluorine concen-
trations in the leaves  of damaged plants  were higher than
those in plants in unpolluted areas. Recently  air measurements
were  made at 7 stations  in a recreation area containing  large
forests and several water surfaces, at the same time as dust
studies  of precipitates  from  washed  and  unwashed birch,
popular,  and plantain leaves.  The  differences found in the
fluorine values (0.5-1.0 microgram F/N cu m in the air and 25.8
mg F/sq.m.  in the percipitate) may be partially  attributed to
the filtration effect of  forests (particularly  with  aerosols)
which results in reduced emissions (the authors' belief). An in-
creased concentration of fluorine in plants is neither proof of
increased  fluorine in the air  nor the cause of plant damage.
Leaves from plants both with and without damage showed an
increased  fluorine  content  with  little  difference between
values.  The most  common fluorine  compound,  calcium
fluoride, does not cause plant damage and occurs only as a
dust which is trapped by dense  forests. Because of this, the
point of collection is important when measuring for fluorides.
Fluoride emissions in industrial concentrations are difficult to
determine because of small  fluoride emissions coming  from
many directions.

FURNACE  SYSTEMS  FOR REFUSE  INCINERATION.

London (England), British Iron and Steel Industry Translation
Service, 25p., May 1966.
Various furnace  systems for refuse incineration are  described
and classified in  terms of size and type of combustion grating.
Grating systems  considered are  the fixed-grate,  the movable
grate without agitation, and the agitated  grate.  Grateless
systems are also reviewed; these include the Riepel-Scherer-
Ridl Process with slagging, the  flame chamber process with
slagging, and the Stauff Process with combustion in suspen-
sion. It is  recommended that special quality liners be provided
for combustion chambers because of excessive  wear  caused
by refuse  burning as compared with coal. A limit of 100,000
kcal/cu  m is set for the fire chamber load. The use of hot
waste  gases to   pre-dry refuse and  to reduce  combustion
chamber  temperature is mentioned. Waste  gas temperature
must be reduced  to 350 C to  assure proper induced draft and
to protect gas purification  equipment. Heat recovery in the
form of steam has limited economic importance.  Ash removal
and  post-sintering  of  refuse ash  to produce  construction
material are also discussed briefly.

TRASH INCINERATION AND  AGGLOMERATING PLANT
IN BERLIN.  (Muellverbrennungs- und -sinteranlage in Berlin).
Brennstoff-Waerme-Kraft,  16(8):409,  Aug. 1964. Translated
from German. Ip.
An incineration plant for city  trash and some industrial' refuse,
scheduled for  completion  in  Berlin-Ruhleben  in 1968, is
described. The refuse, together with heating slag, fly ash from
power plants, and sludge from a  neighboring clarification plant
are processed in an agglomerating belt installation into'admix-
tures for  concrete. Excess  heat  will be  used  for steam  at 24
excess  atm, 430 C for municipal heating  purposes.  When
completed, a daily maximum of 2000 tons can be processed
with a daily agglomerate production of about 1000 tons. This
will correspond roughly to half the total trash output of the en-
tire West  Berlin metropolitan  area. A population of 2.2 million,
with an annual  trash load  of about 3.3 million  cu m (about
870,000 tons), is  projected after 1972.

 CORROSION ATTACK OF BOILERS  BURNING  HEAVY-
 OIL. (Juyu boiler no fushoku shogai). Text in Japanese. Netsu
 Kanri  (Heat Engineering,  Tokyo), 21(3):2-9,  March 1969. 5
 refs.
 Sulfur trioxide is a major cause of corrosion in boilers burning
 heavy  oil. Sulfur compounds in heavy oil are oxidized to SO2
 and SOS  during combustion.  Sulfur trioxi.de combines  with
 water vapor to form sulfuric acid, which corrodes surfaces at
 temperatures below the acid dewpoint of flue gas. Maximum
 corrosion   occurs at 30-40  C  lower  than acid dewpoint.
 Meanwhile,  on  high  temperature  surfaces,  alkali  metal
 sulfates, formed from inorganic compounds,  sulfur oxides, and
 oxides  of  vanadium  accumulate,  impede thermal condition,
 and cause  corrosion. Sulfur trioxide  is  considered to be
 formed by (1) the reaction between SO2 and O2  in the vapor
 phase, (2) the oxidation of SO2 in flame, and (3) the contact
 oxidation of SO2 on metallic surfaces. Calculating the conver-
 sion rate of SO2 to SO3 at equilibrium in (1), the greater the
 O2 and the  lower the temperature, the larger the rate  becomes.
 However, equilibrium does not occur in boilers, so the actual
 conversion  rate is 1  to 4%. In  (2), the greater the amount of
 sulfur  included in the oil and the hotter the  flame, the greater
 the amount of  SO3 formed. These findings  suggest that com-
 bustion with low excess O2 can reduce corrosion. Low-tem-
 perature corrosion can additionally be controlled by additives,
 such as ammonia, magnesium  and calcium compounds; high
 temperature corrosion by carbonates, hydroxides, an© oxides
 of alkaline earth ntetals.

 AIR POLLUTION PROBLEMS AT INCINERATORS WITH
 CAPACITIES UP TO 5 TONS/HR. (Probleme der Luftreinhal-
 tcng bei Abfallverbrennungsanlagen mil Durchsatzleistungen bis
 zu 5 t/h).  Text in German. Energie Tech., 21(6):207-210, June
 1969.
 With the  increasing use of incinerators  for waste  disposal,
 regulations  concerning the  emission  have become  stringent.
 Ver. Deut. Ing. standard 2301 (Feb. 1967) calls for a reduction
 of  stack emission of particulate matter to  200  mg/cu m for
 moist flue  gas  (with a CO2 content of 7%) from incinerators
 with a capacity of less than 1.5 t/hr. Incinerators with a higher
 capacity are to be equipped with the most recent dust collec-
 tors. Efficient  flue gas cleaning depends very much on the
 selection of a suitable cleaning facility. Many factors such as
 grate construction, size of  the combustion chamber,  capacity,
Composition of the waste material, heating  value, excess air,
 and dust concentration of the dirty gas ought to be considered.
 If wet dust collectors are used, waste water purification facili-
 ties must be available. Cyclones and multiclones  can be  used
 presently only  with  incinerators whose flue gases carry low
 dust concentrations.  The advantage of such dust  collectors is
 their small size. Electrostatic precipitators are gaining increas-
 ing importance, particularly when operated in connection with
 a multiclone. But the newest and most suitable dust collectors
 for the present composition of flue gases are probably bag fil-
 ters. Europe's most modern incinerator, erected in Berlin and
 inaugurated in  1968  (capacity  of the  plant is  750 kg/hr), has
 been equipped with  such a facility  after satisfactory results
 had been gained with a bag filter in Switzerland. Depending on
 the  need,  such filters can be equipped  with silicon-treated
 glass fiber  bags  of tubular  shape or with synthetic fiber bags.
 Periodically, the tubes are  shaken to dislodge the  dust and
 cause it to  fall into the collecting hopper. Such filters separate
 dusts which are in the submicron range.

WETTING AGENT 'DB' FOR HYDRAULIC  REMOVAL OF

Addition of 0.01-0.1% 'DB'  wetting agent (polyoxyethylene
ester of ditertiary butylphenol) gives water a surface tension
of 28- 31 erg/sq cm, and used in hydraulic dust removal from
the coke supply for blast furnaces, yields a 70-90% reduction
in dust  with 0.3-1%  moistening. The mixture was tested on
standard equipment at a consumption rate of 0.5-0.6 cu m/hr
or 3 liters of water  per ton  of  coke with 0.08% of wetting
agent; 0.3% moistening. Current tests are being made with  a
7.5 liter/ton consumption  rate and a 0.006 liter/ton wetting
agent.

OPERATING  RESULTS OF  THE INCINERATOR OF THE
CITY OF LAUSANNE.   (Betriebsergebnisse der Muellver-
brennungsanlage der Stadt Lausanne.)  Translated from Ger-
man.  Brennstoff-Waerme-Kraft (Duesseldorf), 20(9):430-432,
01968.
The performance of the Von Roll incinerator in Switzerland is
discussed based on data compiled for the years 1959 to 1967.
Emphasis is placed on investment and operating costs, design
(flue  gases  are  cleared  using  electrostatic precipitators),
operating results, and personnel.  It is concluded that although
the main  task of an  incinerator is the hygienic  disposal of
waste, such a plant should operate with enough safety margin
to avoid long  interruptions. The Lausanne plant owes its suc-
cess exclusively to the standby units and to its design,  which
makes monitoring during operation easy for the personnel.

It has been suggested that manganese  cyclopentadienyltricar-
bonyl (MCT)  be used as  an  antiknock compound in internal
combustion  engines to replace tetraethyl lead. Investigations
which give a general description  of the changes that occur in
the organs and systems of organisms following the administra-
tion of MCT are reported.  The compound was administered by
inhalation to rabbits and white rats.  Results showed that the
MCT is a toxic substance of polytropic action; MCT  vapor
disturbs the function of the nervous system and kidneys,  and
reduces the osmotic resistance of the erythrocytes. It affects
the normal source of the oxidation process  and the processes
of oxidative phosphorylation.  Oxygen inhalation has favorable
effect in acute MCT intoxication.

Sulfur   dioxide is  the  most harmful  gaseous  emission in
Czechoslovakia. The primary source of sulfur dioxide emis-
sion, which reached approximately 25 million tons in 1966, are
power  engineering, e.g.,  powerhouses, boiler  houses, heat
plants, etc., surface mining of sub-bituminous coal in Northern

Bohemia, and domestic fireplaces. The latter are particularly
important sources of pollution in residential and urban areas.
Powerhouses of the Central Board of Power Engineering emit
as much sulfur dioxide as the powerhouses and boiler houses
of industrial plants. Their emissions contaminate the lower at-
mosphere of whole areas. Air quality in the CSSR, especially
in Northern Bohemia and around industrial complexes, can be
raised by controlling the diffusion of sulfur dioxide and com-
bustion products  in  the lower  atmosphere. Less important
sources  of gaseous emissions are  metallurgical  engineering
plants, which produce both  sulfur  dioxide and monosulfide,
and chemical works whose emissions, though low, can be ex-
tremely harmful.  Emissions  from powerhouses of industrial
plants are of local importance.

CEMENT   PLANTS  AND  ATMOSPHERIC  POLLUTION.
PROBLEMS OF DUST REMOVAL.   (Les  cimenteries et la
pollution  atmospherique.  Les problemes  de depoussierage).
Text in French. Equipement Mecan., 48(87):91-95, 1969.
Cement plants  have the  most  formidable  dust  removal
problems among industrial dust  and smoke emission  sources.
The centrifugal, the wet, the electrostatic, and the screen fil-
tering, methods of dust separation are described in detail; dust
sources  and the  dust collecting equipment used in the  in-
dividual successive stages of cement production  are con-
sidered. Quarrying limestone in open air gives rise to moderate
quantities of dust, which are sometimes sprayed  with water.
Pounding and crushing limestone calls  for the use of multitu-
bular centrifuges followed, if need  be, by screen filters. Wet
crushing produces no dust, while  dry or  semi-dry erasing
requires high-capacity, fine-mesh, movable screen filters. Elec-
trostatic filters are  occasionally used  instead. Homogenizing
requires limited dust removal. Drying and  crashing of coal
pose  difficult dust  removal  problems  due to the danger of
coal-dust explosions. Smoke from roasting kilns is the primary
source of dust. Particle size distributions and concentrations of
dusts from six kinds of roasting kilns are given in a Table.
Most modern  kilns  are  provided  with electrostatic filters.
Clinker cooling  uses dust centrifuges. Clinker crashing some-
times uses electrostatic filters but, more commonly, bag filters
with movable  screens. Automatic  cement bagging  machines
usually have movable screen filters made of nylon. At present,
no satisfactory solution of the problem of dust removal in ce-
ment plants exists,  so that the establishment of new cement
plants should still be based on considerations of  dispersal of
dust emissions in the atmosphere.

A computer program was  developed to find the limits  within
which the waste composition may change and to find the ef-
fects of the changes on the various parameters. The program
is executed with  the following values: upper  heating value
from 2225-4450 kcal/kg, carbon from 24-405%, hydrogen from
3.5-7.5%, oxygen  from 20-30%, water from 11-30%, incom-
bustible material  from 11-22.5%,  and carbon/hydrogen ratio
from 10.8-24. It was shown that the heating value increases
with increasing content of free hydrogen. If the waste com-
position and heating value, air surplus, and heat loss are given,
the combustion products at a capacity  of  900  kg/h  can be
found with  the computer program. The specific heats and
enthalpies can be found and a heat equation can be established
to determine the equilibrium  gas temperature. The computer
program also helps  to find the amount of water required for
cooling  flue gases to 540, 400, 260, 120 C, or to  saturation. It
also determines the  mass and volume flow at every important
point in the circulation.  All calculations  include  a certain as-
sumed  percentage of incombustible material.  An  air  surplus
from 40-300% and  a heat  loss from 2-60% of the entire
released heat are included in the input  data. With this  pro-
gram, 2310  various cases can be  computed  and 70,000 in-
dividual data for 21 different waste compositions can be ob-
tained. By feeding the results of analysis of the waste com-
position and its presumable variation over a certain period into
the computer, all parameters essential for the sizing of the in-
dividual parts of the incinerator within a certain determined
range can  be found.

DEODORIZATION OF EXHAUST GAS IN KRAFT PULPING.

The formation of malodorous substances, methy mercaptan
(MMA)  and dimethyl sulfide  (DMS), in  the process of kraft
pulping  was  studied in  two types  of Japanese  pulp  woods:
softwoods (red pine, cedar and Japanese cypress) and  hard-
woods  (beech, poplar,  cherry and pasania  oak). Alkaline
(Na2O)  and  sodium  sulfide (NaS) were added to a 400 g dried
pulpwood block in  an electric autoclave and boiled for 5-1/2
hours at 185 C. Then 5 cc of exhaust gas (raw blow gas) was
sent into the cyclone-separator (a cylinder with the diameter of
3 cm and the length of  18 cm) and analyzed for malodorous
substances (MMA and DMS) by the use of Yanagimoto GCG-
5DH type gas chromatograph. Larger amounts of MMA and
DMS, especially MMA, were produced by pulping hardwoods
than by pulping softwoods. In pulping the same wood type,
the amount of malodorous substances was increased with the
increase of cooking hour and temperature, and the concentra-
tion of  NaS. The  white lauan produced the  same malodorous
substances in quality and quantity  as obtained in the  pulping
of Japanese hardwoods. When the pulping was performed by a
batch system, the concentration of DMS  was  decreased  to
trace with the depression of pressure in the autoclave.

INDUSTRIAL DUSTS   AND  WASTE  GASES.    (Industri-

14(l):20-23, Jan. 1970.                         ;     /
The major sources of dangerous and annoying industrial dusts
or gaseous pollutants are enumerated. In  mines, coking plants,
and gas works, dusts develop  at  the sorting, crushing, and
mixing processes. The extent of dust development depends on
the water content,  the  grain size, and the strength of the
material. Waste gas and  vapor develops behind  driers, trans-
portation  facilities, and in the quenching of coke. The chemi-
cal industry produces the dangerous halogen gases, of which

-------
                                           A.  EMISSION  SOURCES
chlorine and bromine are the most harmful. The maximum al-
lowable longttenn emission concentration for chlorine is 0.1 cu
cm/cu  m air; the short-term value is three times daily 0.5 cu
cm/cu  m air. Hydrogen  chloride develops at the manufacture
of dyes.  The maximum  allowable emission concentration for
fluorine is O.S cu cm/cu m air. Flourine compounds (in gaseous
form or dust) develop in  aluminum production, fertilizer manu-
facture, and at the polishing stations for quartz and glass. With
sulfuric acid production  in a Glaus furnace or in the manufac-
ture of dyes SO2 and SO3  develop. The maximum allowable
concentration  for these  pollutants  is 0.2 cu  cm/cu  m  air.
Hydrogen sulfide has  been  limited to 0.1 cu cm/cu  m air. It
develops  in refineries in  dye and viscose manufacture. A par-
ticularly  noxious  gas is  carbon monoxide  which develops in
phosphorus and carbide plants. Quarries, cement factories, the
ceramic industry, mixers for asphalting highways, iron ore sin-
tering plants, blast furnaces, and foundries all are large  con-
tributors  of dust and gaseous emissions.

The most dangerous and annoying pollutants emitted by  vari-
ous industries are enumerated. Steel  mills  emit primarily iron
oxides  and fluorine compounds. Half of the original fluorine
input is  emitted; the other half goes into the slag.  The iron
oxide emissions, primarily the small particles below 5 micron,
form the brown smoke.  The non-ferrous metal fabricating and
finishing  plants emit metal oxides (cadmium  oxide). When in-
haled,  the  latter may   be extremely  harmful.  The  TLV
(threshold limit value)  is  0.1 mg/cu m air. In aluminum produc-
tion, dust-laden waste  gases develop, despite the wet process.
The aluminum oxide dust content in the rotary furnace is 300-
400 g/standard cu m. In electrolytic reduction of aluminum ox-
ide,  cryolite also dissociates. As  a consequence, hydrogen
fluoride  and dusts of fluorine compounds are found in the
waste gas. The TLV for  fluorides is 2.5 mg/cu m; for hydrogen
fluoride,  2 mg/cu m. In  lead plants 3 to  3.5 cu m waste gases
per kg sinter develop in the  sintering  and roasting station.
They contain 1.5 to 5%  by  volume SO2 and up to 15 g/cu m
dust. The dust contains  lead,  zinc, sulfur,  and small amounts
of other elements. Considerable amounts of  metal vapors
develop.  In the fly dust  of the shaft furnaces, cadmium oxide
or sulfate, arsenic, zinc, and thallium compounds  may be
found.  In copper smelting plants, the waste gases contain fly
dust and SO2. In zinc refining, fly dust (0.1 g/standard cu m)
and SO2 are emitted to  the waste gas. In  ferro-alloy produc-
tion, dusts of various kinds  are carried along in  the waste
gases.  The waste gas quantity of a 10 MW  furnace amounts to
70,000-250,000 cu m/h; the dust content, to  0.25-2.5 g/cu m.

A new low-manganese ferroalloy electrode for use in welding
low-carbon steel at high welding  speeds  is  compared  with
other high-duty  electrodes with respect  to  the amount of
aerosol generated and the manganese content of the aerosol.
As determined by comparative tests, the  amount of aerosol
given off  by the respective electrodes is  approximately the
same, but the manganese content increases as the proportion
of the manganese-containing components  in the coating in-
creases. Contamination of air by toxic manganese compounds
was  significantly reduced by the new electrode whose diame-
ter is 4 mm. The electrode has the same productive capacity as
those 7 mm in diameter.

A total of 36 spruce trees, which  had  shown  resistance to
fluorine-containing pollutants for as long  as 40 years, have
been investigated for five years to determine (1) whether this
resistance  was due  to genetic factors, better  nourishment,
more favorable water supply, etc., (2) what gas concentrations
can  be withstood by  forest trees,  and  (3) if the selected
spruces  can  withstand  higher  concentrations  than  other
spruces of the same age and some deciduous trees  which are
known  to be more resistant. The  results indicate that (1)
genetics is a very important factor and (2) forest damage from
industrial  pollutants can be reduced  or eliminated if foresters
would cultivate pollution resistant trees in industrial areas.

During the period of 3.5 years, twelve cows were kept under
controlled conditions on a farm located in the emission area of
a hydrofluoric acid plant. At the beginning of the test program
the age of the cattle ranged from 3/4 to 9 years. The investiga-
tions covered the computation of the fluorine intake  through
the forage, the water and the air as well as the excretion by
urine and incorporation in the bones. The state of health and
the  productivity of the cattle was constantly observed. The
fluorine content of the farm-produced forage varied largely de-
pending on the situation of the forage land with respect to the
industrial  plant. The monthly average of fluorine intake of the
cattle varied between 1.0 and 9.5 mg  F per kg body weight All
cattle showed symptoms typical for chronic fluorine poisoning,
i.e.  changes  in teeth and bones  as well  as disturbances in
locomotion. No  influence of the fluorine intake could be de-
tected on the fertility or on the  milk productivity  if this was
less  than 20 liters per day. Calves of cows with chronic fluoro-
sis were not injured but do have an increased fluorine content
of their bones.

Red dust emission of the Thomas steel plants were studied
from the standpoint of chemical analysis,  granulometry, and
quantity of dust emitted. The sources of dust were  analyzed
by evaporation alone and by a combination  of evaporation and
oxidation. The  most satisfying theory thus far developed is
that of Turkdogen, Grieveson and Darken, who propose  the
following improvements: when using air, lower the  tempera-
ture at the point of impact; when pure oxygen is used, in-
crease the oxygen at the point of impact,  so as to cause  the
rapid formation of an iron oxide inhibiting layer.

The  centers  of  industrial concentration  in North Rhine-
Westphalia are also those of population concentration.  The
close juxtaposition of these concentrations  of emittants of air
pollutant material and the densely situated population causes
extreme problems. The directed measures of the last ten years
against the unbearable dust load and  the harmful sulfur diox-
ide  emissions have led  to considerable  improvements. Mea-
surements show an extraordinary reduction  of dust and SO2 in
the air since  1963. While infringements on the dust limit values
were found on 22%  of  the  measurement surface at  the
beginning of the measurement period with  5% of the measur-
ing  surface violating the SO2 limit value, in the year 1968
violations were  5% for dust and  1% for SO2. These successes
were predominantly due to severe licensing practices for new
industrial plants and improvement programs for existing indus-
tries that do the most to determine emission  concentrations:
steel converters, ore sintering plants, coking furnaces, foun-
dries, and steam power plants. The experiences of the last few
years have shown that the problems  of air pollution are sub-
ject  to change  and  have  a  continuous  connection  with  the
developments in technology and production in industry. An in-
crease of around 25% to 5 million tons SO2 emissions per year
is projected from 1967 to 1975. From 1975  on, the  production
of electric power, which will then account for 40%  of the SO2
emissions, will  be considerably influenced  by atomic energy;
S02 emissions will first stop their increase and then start to
decline.  Fluorine, hydrocarbons, chlorine, and numerous odor
substances  will  become  the  focus  of  attention. The dust
problem will no longer be a question of loads due to coarse
dust, but dangers to health due to  fine dusts.  Precipitation
measurements will be extended to include concentration mea-
surements. In the coming 10 years, the State will also take an
increasingly  critical  look at emissions from automobiles and
domestic heating  units. The goal of the  State Government is
the  development of a control system on a regional  basis. Data
banks will be set up to provide regional data on individual in-
dustrial emission sources, as .a tool to the development of con-
trol programs.  This program has already begun in the area of
metropolitan  Cologne and will  soon  be  extended to  the
Duisburg/Oberhausen/Mulheim a.d. Ruhr, Essen/Bottrop, Gel-
senkirchen/Wanne/Eicket/Bochum, Castrop/Rauxel, and Dort-
mund regions.

Research is reported which deals with new work in the field of
coal decomposition at high temperatures (up to 10,000 K), the
state of the knowledge pertaining to reaction kinetics of the
gas formation during thermal decomposition  of coal,  and the
correlation between bituminous coal analysis  and combustion.
Through  the development of high-energy plasma burners and
lasers, experimenters can  now perform the thermal decomposi-
tion of coal using extremely  high temperatures and  cor-
respondingly high heating rates. Additionally, differentiating
physical instruments for the  determination of the products of
pyrolysis, new  methods for  the evaluation of measured  data
by the  use of computers, and new techniques for the heating
of coal samples facilitate exact studies of the reaction  kinetics
of the gas formation during pyrolysis. Discussion is presented
pertaining to the thermodynamics of coal at high temperatures,
the kinetics of coal pyrolysis, and the  correlation of pyrolysis
with other reactions  occurring during the combustion of in-
dividual coal particles.

SURVEY  ON  THE  PUBLIC  NUISANCE  BY  OFFENSIVE
ODOR.  (Akushu kogai gairon). Text in Japanese. Kuki Seijo
(Clean Air - J. Japan Air  Cleaning Assoc., Tokyo), 8(2):34-46,
June 1970.12 refs.
Offensive odor  as a public nuisance can be classified  accord-
ing to  its  composition in the  following industrial sources:
hydrocarbons and mercaptan from petroleum refining; organic
sulfur compounds such as mercaptan from paper  and pulp fac-
tories; and amine and fatty acids from fish meal and rendering
factories  and stockyards. Odors of each category  are  ex-
plained. While it is well established that olfactory reception is
caused by a stimulus given to nerves by gaseous substances or
air-borne particulates, the mechanism of the stimulus is  not
yet known. Odors of industrial waste water are classified into
the following, that is,  aromatic, free chlorine,  disagreeable,
earthy,  fishy,  grassy, moldy,  musty,  peaty,   sweet,  free
hydrogen  sulfide,  and  vegetable.   Weber-Fechner's   law,
fatique, personal differences, and interference  of  odors  are
described. Definitions of threshold and odor concentration are
provided. Measuring methods of  odor include dilution by  air,
equilibrium with salt water, and a method used by processing
factories  to monitor the total  amount  of  odor substances.
Physical  or  chemical methods are available for odor abate-
ment. Scrubbers, condensation by cooling, adsorption by ac-
tive carbon, and dilution  by air are in the physical category,
while chemical  methods  include  processing by  acid, alkali,
chlorine,  or ozone, ion exchange, masking, recombustion, and
catalytic combustion.

haust gas are the heavy hydrocarbons. Their effects and those
of other components on underwater plants and animals were
studied by chemical and biological tests and by taste checks of
fish. The motor tests were performed with new motors or mo-
tors past the break-in period. They had nominal powers of 6,
18, and 40 HP and were operated with fuel-to-oil mixtures of
1125, 1/50, and 1/100. After 350 hours, as a consequence of
wear and tear, medium power class motors consumed 10-25%
more fuel and  emitted more toxic  substances.  The average
data  double  at idle or full load  operations. Any  improvement
of the motors which leads to a lower fuel and oil consumption
would  reduce  the emission of  pollutants  to water.  Results
show  that  the  permissible fuel-to-water  ratio  should  be
changed from 1/100,000 to 1/200,000.

The following are the decisive factors in selecting the method,
the furnace  system,  and the reaction conditions for incinera-
tion or thermal cracking of industrial sludges: combustibility,
volatility, and toxicity of the individual components; the water
content;  the mineral substances; and corrosive compounds.
The  most common  types of furnaces (such as combustion
chambers, story of fluidized bed furnaces) are surveyed,  and
their design, mode of operation, and field of application are
discussed. Most incinerator  plants use both combustion  and
thermal cracking. The legal  requirements of total residueless
combustion  of all toxic organic components demand com-
bustion  temperatures of  at  least 800 C in  the  actual com-
bustion zone of the  furnaces. With many residues, this tem-
perature  cannot be reached without auxiliary fuel. A rotary
burner, spray  burner, an atomizing nozzle, a story furnace,
and a fluidized bed furnace  are illustrated. The  fluidized  bed
incineration  with  a turbulent layer of inert material may be
also used for thermal cracking of waste sulfuric acid from in-
organic or organochemical plants. The waste acid concentrated
to an acid contents of 45% (including solid substances,  mostly
sulfates) is pumped into the turbulent layer of  sand, heated by
an auxiliary  burner, and cracked to water vapor,  O2, and SO2.
The  sulfates are converted to oxide, and organic substances
are incinerated. The  spent hydrochloric acid and iron chloride
containing pickling baths are thermally cracked.

Tamaulipas; Piedras Negras in  Coahuila;  Ciudad  Juarez in
Chihuaha; Nogales  in Sonora;  and Mexicali,  Tecate,  and
Tijuana in Baja California. The  survey was based on the con-
sumption of raw  material and output from various emission
sources. Air pollution was found to stem mainly from natural
sources (pollen, dust, bacteria); emissions from internal com-
bustion engines were the second largest  source. Industry in
these areas is in  beginning stages, with  small plants (fewer
than 100 workers) predominating; present plants which may
eventually contribute to more  serious air pollution problems
include petroleum installations,  a steel smelting plant, metal-
lurgical,  insecticide plants, a brewery, and factories  which
manufacture construction materials. Brief results of the survey
are given for each city.

Thermal waste gas treatment is by far the  most efficient
method, but also the one with the highest operating costs, for
the reduction  of  odorous emissions  from  animal rendering,
coffee roasting, pyrolysis of beech wood, and foundries. The
waste  gas is pressed into a combustion chamber where  guide
vanes  impart a rotary  movement to  the gas. The oil or gas
burner is tangentially attached to the cylindrical chamber wall.
Waste gases from a coffee roasting plant  could be cleaned
from 575 mg C/cu Nm to 170 mg C/cu Nm when temperatures
in the chamber did not exceed 485 C. Better results are ob-
tained at temperatures between 680 and 800 C, while concen-
trations of more than 10 g/cu Nm in  the uncleaned gas  could
be reduced to less than 100 mg C/cu Nm at 740 C. Catalytic
oxidation has found wide-spread use in the past few years, in
which it generally suffices to heat the waste gases to just 350
or 400 C. Thus, costs for energy can  be saved. Catalysts with
palladium or platinum as active  ingredients are used. Efficien-
cies of 90 to 95% are achieved with this method, but a higher
maintenance service is  required. Deodorization of the air in a
poultry farm and pig sty by addition of ozone was unsuccess-
ful. Better results were obtained in a mink farm by soaking a
bed of sand with potassium  permanganate solution 100g/12
liter water, 1 liter solution per 1  sq m  sand).  Mink feces falling
onto this soaked bed were deodorized to a large  extent. No
final results are available as experiments with this method are
still in progress.

A study was  conducted on the spontaneous combustion of
flour dusts or dusts created in the course  of its production.
The spontaneous-combustion temperature of flour dusts and
flours  were determined by the Swietoslawski and Roga method
and by the Hulanicki and Glowiak method. The device used to
determine  the self-ignition  temperature  of  the dusts  is
described. Induction times were determined for all dusts at
temperatures  of 300 C, 320 C, 340  C, and 360 C, and their
logarithms were plotted as straight  lines. The dusts can be
separated into  two classes with respect to  the ease with which
they spontaneously bum: dusts from rye, wheat,  and  barley
flours  and dusts that are separated in the grinding operation,
with a maximum safe temperature of 128 C; and  dusts from

the grain cleaning process, which are difficult to ignite, with a
maximum safe temperature of 220 C. The spontaneous  com-
bustion temperatures of all the dusts which were studied by
the Swietoslawski-Roga method vary within the range of 250-
275 C. This range is hazardous for all operations that involve
grain and flour dusts. The curves of temperatures of self-igni-
tion vs induction times make it possible to determine self-igni-
tion temperatures for any arbitrary induction time or to state
how long it will take dust at a given temperature to reach the
self-ignition point. (Author conclusions modified)

Components  from   motor  vehicle  combustion  gases  are
discussed in terms of  concentrations  emitted and the symp-
toms which they produce. Narcotic  properties  of  saturated
hydrocarbons increase  with  an increasing number of carbon
atoms in the molecule, while all hydrocarbons mixed with air
in suitable  proportions  form  explosive mixtures. Hydrocarbon
vapors above C5 do not  require high concentrations, and a
concentration of 1 ing/liter is sometimes sufficient to cause
dangerous effects in the human organism in a period of a few
minutes.  Ethylene, propylene, butylene,  hexylene, and hep-
tylene induce almost the same disease symptoms as hydrocar-
bons of the paraffin series. A permissible concentration limit
of  0.1   mg/liter  is  recommended  for  these  unsaturated
hydrocarbons of the  ethylene series. Diolefins act on mucous
membranes  in  the  gaseous  or  vapor  state.  Unsaturated
hydrocarbons of the acetylene series oxidize more readily than
hydrocarbons of the paraffin and olefin series, and are able to
very easily attract atoms, atom groups, and particles  from
other compounds to their molecules. Fatty acids and their an-
hydrides  act destructively on tissues, while formaldehyde is al-
ready able to lead to  chronic intoxication at a concentration of
0.02-0.07 mg/liter. Aldehydes  induce diseases of the respiratory
tract, liver  and kidney  diseases, and diseases of the eyes and
skin. Pure  ketones produce diseases  of the respiratory tract,
the eye  protective system,  and  diabetes and anemia. The
human organism can tolerate a maximum of 0.01% CO  by
volume on  continuous  action  for 8 hours daily. Intoxication
causes  loss of consciousness, convulsions, breathlessness, and
asphyxiation. Swelling of the lungs occurs in severe cases of
intoxication from nitrogen oxides, while sulfur  dioxide acts
similarly  as a powerful irritant, especially on the mucous mem-
branes.  Gasoline  vapors  induce diseases  of the respiratory
system, nervous system,  and the protective system of the
eyes. Toxicity of gasoline vapors increases with increasing CO
content in the mixture,  and mental disturbances are among the
chief symptoms of acute tetraethyl lead intoxication.

COMPUTATIONAL    METHOD     OF    DETERMINING
FLUORINE BALANCE DURING ALUMINUM ELECTROLY-
SIS. (Raschetnyy  metod  opredeleniya balansa ftora pri  elek-

The following quasiempirical formulas for fluorine loss during
electrolytic production of  aluminum are presented: 1) loss with
exhaust gases  as  a function of cryolite content of the  elec-
trolyte and electrolyte temperature; 2) loss with fettlings as a
                         function of service interval; 3) loss in the form of CF4 as a
                         function of the number of anode effects, duration of anode ef-
                         fect, and % yield in terms of current; 4) mechanical loss as a
                         function of the fluoride content of the  raw material; and 5)
                         loss with the  coal ash. Fluorine loss through exhaust gases is
                         reported for three installations and ranges from 18.97 to 25.63
                         kg/t. It is estimated that cooling the process by 5 degrees C
                         will reduce fluorine consumption by 0.2 kg/t, while increasing
                         the  cryolite ratio by  0.1 will affect approximately  a 3 kg/t
                         savings.

                         The  process  of  formation  of carbon black particles during
                         decomposition of hydrocarbons in an industrial reactor can be
                         described  by  the Semenov equation  for  branched  chain
                         processes with quadratic breaks in the chain. The specific sur-
                         face of the carbon black can be determined by theoretical cal-
                         culations  according to  the  technological  parameters of  its
                         manufacture. The heating up  and evaporation of hydrocarbon
                         raw material, and also the formation and growth of carbon
                         black particles, occupy (2-3) times 10(minus superscript 3)s in
                         an industrial reactor with gases moving at a speed on the order
                         of 300-400 m/s in the zone  in  which they are mixed  with
                         hydrocarbons. Atomization  of the hydrocarbon raw  material
                         by high-temperature gases from  the complete combustion of
                         the  fuel at a high relative rate of motion ensures that the raw
                         material will be heated at a high rate. In this process, the mag-
                         nitude of the specific  surface of the carbon black depends on
                         temperature  and hydrocarbon concentration in the  reaction
                         gas. The temperature of the gases in the reaction chamber of
                         an industrial reactor is not consistent along its length. Due to
                         exothermic reactions,  the temperature rises rapidly in the ini-
                         tial zone.  It achieves the maximum at the moment of total con-
                         sumption  of oxygen, then is reduced by exothermic reactions.

                         Even though the only aluminum produced in Germany today is
                         manufactured by an electrolytic  method,  fluorine emissions
                         are  still 500 kg per day. In the area of one plant, the  quantity
                         of fluorine sedimented per acre in 1956 amounted to approxi-
                         mately 7 kg at 300 m  from the plant, decreased rapidly to 0.9
                         kg  at 700 m,  and then  decreased slowly with increasing
                         distance.  Severe clinica phenomena  have  been observed on
                         vegetation at quite distant locations and can be attributed only
                         to airborne fluorine. Moreover,  feed plants (hay and grass)
                         have been damaged,  even when  their  fluorine  levels were

Dutch paint manufacturers are well aware of the fact that ap-
plication of the products of the paint industry does contribute
to air pollution. This awareness has resulted  in a joint in-
vestigation by paint manufacturers and TNO into the contribu-
tion  of paint producers  and paint users to air pollution in the
Netherlands. From information received mainly from members
and co-members of the Vereniging Voor Verf-Research (Dutch
Society for Paint Research) it was calculated that paint produ-
cers  and paint users are  together responsible for approximately
0.1% of the harmfulness of air pollution in the Netherlands.
Moreover the conclusion was drawn that the percentage men-
tioned will decrease slowly in the coming  years. (Author ab-

HIGH  PERFORMANCE  INCINERATION  OF  SEWAGE
SLUDGE. PART II. INCINERATOR  WITH SLAG-TAP  FUR-
NACE.  (Konoritsu no  gesui odei  shokyaku sochi ni kansuru
kenkyu. ni. Yukaishiki odei shokyaku sochi). Text in Japanese.
Nenryo Kyokaishi (J. Fuel  Soc. Japan, Tokyo), 49(521):674-
682,  Sept. 20, 1970. 7 refs.
A new  type of incinerator  with a slag-tap  furnace for de-
watered sludge consists of an  atomizing feeder of sludge, a
heat exchanger,  an air preheater and a cyclone  dust collector.
The  air-jet type sludge atomizer, referred to in Part I of the ar-
ticle, and a heavy fuel oil burner are placed at  the top of the
furnace. Refractory materials which are packed in the furnace
are suspended by five water-cooled tubes with refractory coat-
ing and are heated by firing fuel oil. Dewatered sludge is fed
in particulate form  and burned immediately  when it gets  in
contact with the high temperature, high speed combustion gas
of the fuel oil. Ash  in the sludge is melted into  slag and  flows
down into  a slag pit through the bank of refractory materials.
The  incinerator system  has the following merits: dustless flue
gas is emitted from the furnace, because the ash in sludge is
melted into slag at the bank of refractory materials; flue gas is
odorless because of high temperature combustion; and the in-
cineration plant can be compact in size and still  possesses high
performance. This type  of incinerator is used more effectively
for dewatered raw sludge than  for dehydrated sludge, just as
in the case of the AST method, since dewatered sludge con-
tains more  water and is more convenient for  transportation
and  dispersion. Further, since dewatered raw sludge has not
gone through digestion, it contains more organic matter and
emits higher heat. The system is applicable to not only sewage
sludge, but also  for burning  sludge in factory effluents which
hardly contains any flammable  matter, or the sludge which is
especially high  in water content. The system is only a  small
test  incinerator,  with only 100  kg/h capacity. After more ex-
perience is gained in taking out  melted ash and in testing dura-
bility of the incinerator,  more problems will be solved.

To ascertain their suitability for use in  pressurized manned
chambers, various polymers  were placed  in an enclosed pres-
surized chamber and toxic compounds in their gas emanations
were measured.  The studies were  conducted  at temperatures
up to 200 deg at reduced oxygen pressure (0.2-0.4 atm), and at
atmospheric pressure. More than 25 materials were tested, in-
cluding  those based  on  polyvinyl  chloride, caprolactaum,
polycarbonate,  polyurethanes,  natural and  synthetic fibers,
rubbers, sealings, glass plastics, and plexiglass. The most toxic
of these  materials were glass  plastics and sealings; the least
toxic were rubbers and caprolite. The hygienic properties of
polymers can be improved by  vacuum processing, addition of
stabilizers, heating, and washing with water. (Author abstract

Smoke  from  fusion  furnaces of  glassware manufacturing
plants was investigated with respect to dusts,  sulfur oxides, air
ratio, and penetration rate. The concentration range for dusts
was 0.13-0.21 g/N cu  m.  For a factory manufacturing glass
parts for optical instruments, the average was 0.46 g/N cu m.
For a thermos  manufacturing factory, the average  was 0.66
g/N cu m. Since  the process involves very high temperatures
for the production of hard glass, the amount of dust decreases
very rapidly after the operation has begun. Ways of preventing
pollution include recombustion of waste gas at a high tempera-
ture, maintaining  the  viscocity  of the  fuel  by  adding low-
viscocity fuel such as  kerosene, and avoiding drastic cooling
of the furnace.

The main potential sources of air pollution from the petroleum
industry, excluding the petrochemical industry, are given. The
emissions  are compared  with those from   power stations,
domestic fuel, and motor traffic. Emissions of nitrogen oxides,
hydrocarbons, carbon  monoxide,  and particulates from  the
petroleum industry  are low in comparison with those arising
from other sources. The industry s most important pollutants
are sulfur  dioxide and  odorous gases. Dispersion from high
stacks is  often an effective means of solving local pollution by
sulfur dioxide.  For odor abatement,  prevention is the best
method; examples are  given. The problem of abatement cost
and norms are briefly discussed. Where health is not impaired,
the aim should be a low cost/benefit ratio. The industry is not

At the present time, two-cycle gasoline engines are clearly less
advantageous than four-cycle engines principally because their
exhaust gases contain  large quantities of emitted  hydrocar-
bons. In some  ways, however, two-cycle  engines are mechani-
cally  superior. The  construction and  characteristics of two-
cycle engines are discussed, as well as exhaust gas composi-
tion, afterburners, and  fuel injection. As a general  rule,  it is
possible to sustain a flame reaction throughout all operating
limits including lean air-fuel ratios, if  the temperature of the
                        reactants is kepy high by utilizing a heat exchanger.

With the increasing cement consumption the production plants
of the  cement industries are on the whole fully employed. To
some  extent they were enlarged by new plants in order  to
satisfy the demand for cement. According to temperature, con-
tents and  components of dust,  the quantities  of air or  gases
escaping from the production plants are dedusted by various
dust extraction plants,  e.g. centrifugal dust-extractors, fabric
filters, gravel-bed filters, electric dust extractors,  so that a
vast reduction of  the  dust  emissions  will be  reached.  To
produce one ton  of cement some 2.8 tons  of raw materials,
gypsum, clinker,  and coal of rough or fine quality must be
crushed to powder. During  the  various stages of production
the fine crushed  material always mixes with  cold air or hot
gases,  and  this necessitates a further separation. The removal
of the  fairly considerable dust contents of  raw gases and the
observance of  the required  limits of emissions  not only are
diccicult technical task  butr also cause considerable 'financial
costs by capital expenditure  for new plants, their management
and maintenance.  (Author abstract)

In the l-eucr.il Republic of Germany,  rigorous  scales were
evolved for the supervision of emissions from industrial plants
by the Federal Regulations issued in 1959 in the  interests of
clean  air, and  by the technical regulations of 1964, which set
limits for these ('Technical Directions  for Clean Air,  TAL').
This applies in  particular for the requirements  which were
placed on the emission of dust  from large  coal-fired  boilers
particularly when the fuel has a high ash content. Results of
numerous  experiments  on  large, electric  dust removers  for
bituminous  coal and brown coal-fired boilers - carried  out by
the Technical Supervisor Groups in Essen and the Rheinland,
show  the developments over the past few  years towards ever
higher separating achievements. Effects of various factors, in
particular the properties of the fuel and the combustion condi-
tions  , were visible on  dust properties  and separating  results.
The limits reached today in this  sector are indicated. (Author

The increasing  incidence  of gasoline engines   necessitates
reducing the air pollutants  from exhaust gas by 40% within the
next 10 years. The influence of engine  operation on the emis-

described, e.g., in high gear, while changing  gears and speeds
(7-mode California test), and in neutral. Limiting values for
emissions dependent on motor size and normal usage are sug-
gested. Methods to reduce exhaust gas pollutants included  fuel
injection systems to replace carburetors and  controlled turbu-
lence  techniques.

The objects of this investigation were to study the possibility
of separating by means of mechanical processing at least part
of the sulfur contained  in Polish coals; to earmark those collie-
ries which possess S in  such quantitities as to make feasible an
industrial  separation of pyrite  from coal;  to  establish  the
technological approach. Only pyrite coal is considered  herein.
The use of the sulfur obtained from pyrites by the ^fiemical in-
dustries is  considered  most desirable.  Products  totalling 69
from 26 collieries were  examined as follows:  (1) by jigging; (2)
by enrichment of products on concentrating tables  (considered
the most appropriate approach); (3)  enrichment by flotation,
mostly applicable to slurries. It was established that, by treat-
ment on concentrating tables, pyrite concentrates of S  content

HANSHIN WET TYPE DUST COLLECTORS.  Clean Air Heat
Management (Tokyo) 15, (5) 5-11, May 1966
There are  three models of Hanshin Wet Type Dust Collectors
for collecting different kinds of dust and they all operate on
the same principles. Contaminated exhaust gas is forced into a
water tank equipped  with  turbulance control plates through
nozzles  at a high speed. The gas is cleaned while in  contact
with the water. The HJ model is for  collecting fine particles
from such materials as sand, cement,  activated  carbon and
brick. The typical collection efficiency for various particle size
distributions is approximately 99%. The HIS model is designed
for use with oil and  coal burners. The mechanics of this model
are the  same for the HJ models, but the HIS model requires
the addition of a sludge tank. The concentration of soot in the
exhaust gas is reduced by a factor of two. Appropriate sizes of
HJS models  for  different boiler  sizes  are  tabulated. HJG
models  are designed for the treatment of gaseous contamina-
tion in exhaust gas. They have the same structure as  HJ and
HJS models except  that a de-mister is added at the top of the
tank. The  absorption efficiencies for H2S, C12,  SO2 and NO2
are tabulated. The efficiency of 98.5% is obtained for H2S by
addition of NaOH to the tank water.

The utility  of  electrostatic  precipitation  in the  working
premises of a  rolling mill is discussed in connection with
cleaning of oily fogs  and  emulsion  fogs generated by rolling
processes. From an economic point of view the considerable
costs for the installation of an electrostatic precipitator can be
amortized in a relatively short time. Its simple maintenance,
safety of operation and effectiveness should be considered.

152-4, Mar. 16, 1967. Ger.
Substances used for sizing and lubricating in pressure die cast-
ing such as mineral  oils  and aluminum powder cause con-
siderable air pollution hazards to the operators. Therefore, ef-
fective exhaust hoods capable of removing dust and mist must
be  employed.  Because suspended particles of fats and oils
have a  tendency to condense in the exhaust  pipes creating a
fire hazard, the dust removal plant must be close to the hoods.
While tests using  dry  and wet prefiltering brought no satisfac-
tory results, electrostatic filters of the two-zone type  (13 and
6.5 kv) were  successfully  employed. Once a week the alu-
minum plates charged with dirt are cleaned in hot water (con-
taining a 7.5% detergent solution) agitated by jets in about 4
min. Complete interchangeability of the parts  to be  cleaned
greatly facilitates  servicing a number of die casting machines.

                         fore, effective exhaust hoods  with subsequent dust and mist
                         removal must be employed. Because suspended particles of
                         fats and oils have a tendency to condense in the exhaust pipes
                         creating a fire hazard, the dust removal plant must be close to
                         the hoods. Where this is not possible, pre-filtering by wire
                         nettings built into the hoods proved advantageous. Forty-five
                         per cent of the pollutants, mostly the coarser  materials like
                         aluminum, dust, and fats are retained by the netting while sub-
                         stances such as oil and soot reach an electrostatic filter. Ex-
                         tensive test on the system, performed in southwest Germany,
                         indicated a 98% efficiency. Venturi-washers could also be used
                         instead of electrostatic filters but wet-washers (wet cyclones)
                         proved insufficient.

                         from the combustion gases of large power plants is discussed
                         in  reference  to large-scale field tests at Criel and Blenod in
                         France. The health and the problem of welding containers that
                         have contained SO3 are discussed. It was found that when 17
                         ppm of SO3 was injected into the gas stream before the elec-
                         trostatic precipitator, the results with two units  were equal to
                         that  obtained with three electrostatic precipitators. The test
                         which showed the best results with a yield of 98.5% with 250
                         MW on the precipitator used 47 kg of  SO3 per hour or more
                         than a ton a day. The improvement was equivalent to a gain in
                         yield  of  4.5%. However, there  are  difficulties in protecting
                         people and the cost  of installation is high. It is premature at
                         this  point to generalize  as to  whether the  use of SO3 is
                         economical as a substitute for an electrostatic unit in a group
                         of units. If further tests  verify the present work,  the use of
                         SO3 could be considered a valuable, but difficult  method of
                         improving the efficiencies of electrostatic precipitators.

                         Diesel exhaust emissions and methods of  controlling  these
                         emissions in Sweden are reviewed. The diesel  engine differs
                         from  the  gasoline engine in  several respects, which have a
                         decisive influence on the pollution it emits. It uses a fuel that
                         is  less volatile than gasoline.  It normally works with a higher
                         excess of air (leaner mixture) and the devices for feed and ig-
                         nition of the fuel are quite different. Due to the discharge by
                         individual vehicles of dense  smoke  and by  the discharge of
                         foul-smelling substances  they have been pointed out by the

public  as qualified air polluters. Poor maintenance of the en-
gine or intentionally wrong pump adjustments can result in the
giving  off  of such dense  smoke  that this can constitute a
hazard for overtaking  vehicles due to impaired or obscured
visibility. Diesel engines can give off various types of smoke.
One type is the heavy  load smoke, which arises through load
on a hot engine. Exhaust gases from diesel vehicles, especially
under certain driving conditions, contain substances that are
irritating to eyes, nose and throat. These  include: oxides of
nitrogen, hydrocarbons,  polycyclic  aromatic hydrocarbons,
carbon monoxide and sulfur dioxide. The smoke from a diesel
engine  can  be limited by various measures, undertaken on the
engine  or the fuel pump, the fuel,  and finally on the exhaust
gases. Regular maintenance of the engine is necessary to keep
the smoke  values  at the  lowest possible level. Current and
proposed regulation of diesel exhaust emissions are discussed.

In 1966, the Research Institute of the Cement Industry in Ger-
many performed 270 measurements at dust collection installa-
tions in 37  cement plants.  The results, pertaining for  the most
part to  electrofilter installations, are summarized in  6 tables.
The individual measurement conditions are reported. The mea-
sured values provide a survey of the present position of dust
collection technique for cement kilns. The limiting values  at
present specified for the dust content of the cleaned gas are
indeed usually conformed to if the  dust collection plant is cor-
rectly designed, but at the present stage of technical develop-
ment troubles still often occurr which impair the collection ef-
ficiency. Conditioning  of  kiln exit gases  by water spraying,
especially  in the case of rotary kilns  with suspension pre-
heaters in  direct operation, continues  to  present difficulties.
The prevention of the  infiltration of  'false' air and constantly
applied proper  maintenance contribute much to  ensuring that
the dust collectors maintain the required collection efficiency
under continuous working conditions.

ELIMINATING  ODORS BY CATALYTIC COMBUSTION.
((Die Geruchsbeseitigung  durch katalytische  Verbrennung.))
Text in German. Stadtehygiene (Uelzen/Hamburg), 16(3):55-61,
Mar. 1965.  11 refs.
With the rapid  growth of  the chemical industry, air  pollution
by odors has also increased. Catalytic oxidation and reduction
offer possibilities for an  economic solution of  the  problem.
The principles of catalytic reactions  are described. In a table
the properties of four catalysts are compared with each other.
These catalysts are: platinum on metal, platinum-palladium on
ceramics, copper-chromium on aluminum oxide,  and  platinum
on  ceramics. The effectiveness of a catalyst depends on the
gas  mixture, the temperature,  the type of catalyst, and the
ratio:  volume  of gas/hour/volume  of  catalyst.  The heat
generated by the catalytic process is usually used to preheat
the gas before  it enters the catalyst. If the concentration of
combustible substances is sufficient, steam may be produced
in addition. An  example is quoted where 47,000 cu. m. gas per
hour with a latent heat of 400 kcal/cu. m. produce 31 tons of
steam per hour. The equipment pays for itself in 2 1/4 years.
For gases of low heat content, catalytic combustion under in-
creased pressure is advantageous.  Most economical  is a gas
turbine which compresses  the gas and, after it has passed the
catalytic chamber, uses the hot cleaned gas. The use of a gas
turbine is recommended for gas volumes of more than 100,000
cu. m./hr, if measures for air pollution control become neces-
sary.

Complaints by  the neighborhood of a fish processing plant
about annoying odors led to a series of experiments to deter-
mine  an economical way for cleaning the plant's waste gas.
Drying  of  fish  meal can  be  done  in  three ways:  1)  the
azeotropic method with perchloroethylene which is rather ex-
pensive; 2) steam drying; and  3) fire drying.  The waste gas
from  steam drying is rich in amines, and from  fire drying rich
in sulfur dioxide. Both carry large amounts of reducing sub-
stances. Spraying the gas  in  two steps brought  satisfying
results.  In the first stage the waste gas is sprayed with a base
and in the second stage with diluted sulfuric acid. In this stage
agglomeration of aerosols from the drying fish meal occurred
which were to  a large degree responsible for  the bad odors.
This two-stage washing method, together with the 1:1000 dilut-
ing effect of a high chimney were sufficient to eliminate the
obnoxious odors from the fish meal plant.

Waste gas from  the production of fish meal  contains up to
about 200 mg/cu m  of ammonia, 15 mg/cu m of substances
containing sulfur (H2S and mercaptans),  5  to  10 mg/cu m of
carbonylic compounds, and sulfurous and organic acids up to
100 mg/cu m. There are also substances which are reduce by
potassium permanganate, of the amount of 1000 to 1500 mg/cu
m.  Such waste  gas could be  successfully deodorized by a
three- stage scrubber. In the first stage the waste  gas is cooled
below 30 degrees C by spraying it  with  water in a jet spray
tower. The second tower used 2% NaOH and  sodium  bleach,
and the third tower sprayed 0.5% H2SO4. Cooling below 30
degrees was necessary to reduce the concentration of  organic
(mostly oily) compounds. Results of other experiments in this
series are also reported in the form of th*ee tables.

One of the most important tasks of control of the efficiency of
ventilation  devices  is the obtaining of reliable and accurate
results of determination of dust concentration  in the air flow,
moving through the air duct. Up to the present time the direct

-------

AIR POLLUTION TRANSLATIONS
method of  dust concentration  determination  is  the  most
frequently used method and consists in aspirating and filtering
of a portion of the flow through some kind of analytical filter.
This method provides for the measurement of the volume rate
(flow rate) of the aspirated air,  the length  of sample taking,
and the amount of the settled-out dust. With these  values the
dust concentration, expressed in grams (of milligrams) in one
cubic meter of  air is calculated. Indirect methods, based on
the measurement of the indexes  of the physical properties of
the dust flow, so far  are not widely used. In the determination
of dust content of the ventilation flow, the samples are taken
by means of a dust-drawing tube, introduced into the  air duct.
An important condition for obtaining correct results  here is the
observance of equal rates of movement of air in the aspirating
opening of the dust-intake tube and in the investigated air flow
(the rule of isokinetic condtions of sample taking). Thus, prior
to taking samples for the dust content in the air ducts the rates
of the  air movement  in them is measured. The problems con-
cerning the technology of measuring the air flow rates are suf-
ficiently expounded in special reference and instruction litera-
ture, and are stated  here very briefly. Investigations of the
dust content in ventilation system air ducts, estimate of the ef-
ficiency of dust  collecting devices,  and various mathematical
considerations are discussed.

A report is given in which the 'Purity of the air in the vicinity

plants  in the vicinity  of Cressier which may  pollute the air: a
cement factory,  a refinery, a thermal paper  mill, and a plant
for the drying of potato flakes. In the refinery, several steps
are taken to ensure air purification:  the use of floating covers
to prevent vaporization of volatile compounds  from drying
pans, siphoning off and burning of noxious vapors,  prepara-
tion of odorless sulfur from H2S and mercaptans, and the use
of refinery  gas to limit sulfur dioxide emissions. In  contrast to
water pollution, the area of air pollution may entail  psycholog-
ical problems such  as fears of sickness from breathing noxiuos
odors, of impaired breathing, or even smothering.

The  increased upgrading of oil  refinery processes—requiring
additional  sources of hydrogen-is  advocated for Germany.
Despite added costs,  such steps should result in financial gains
of over 60  percent; moreover, the probable future  limitations
of sulfur content in fuels by means of governmental air pollu-
tion  control regulation also suggests increased  use  of such
hydrogen refining processes. Other technical advantages of the
use of hydrogen production facilities are cited. The conditions
and costs of hydrogen production for three different processes
(steam methan pyrolysis, steam naphtha pyrolysis,  partial ox-
idation) are tabulated. In the future  it may be desirable, as an
                         air pollution abatement measure, to combine thermal power pl-
                         nats with refineries so as to convert the heating oil to heating
                         gas through partial oxidation =  should this actually become an
                         accepted practice, considerable  added savings in hydrogen
                         production—hence in upgraded refinery processes—will be real-

                         The efficiency of the dust collection mechanism in wet collec-
                         tors,  which remove  dust  from  the  atmosphere  by  water
                         droplets, has heretofore  been  obtained from the mean  diame-
                         ter of the water droplets  and the dust. However, since the par-
                         ticle size of droplets and dust  varies widely, consideration of
                         particle  size distribution becomes necessary. A mathematical
                         analysis was made to determine the influence of particle size
                         distribution of water droplets  on the  impaction or diffusion
                         collection  efficiency, assuming the use of a Venturi scrubber
                         dust collection mechanism. The results are:  1) as the range of
                         particle  size  distribution  widens, the impaction  efficiency
                         decreases,  while it remains constant when derived from the
                         volume  mean diameter;  2) in diffusional collection,  as the
                         droplet  diameter diminishes,  the washing factor  becomes
                         larger and, when the range of the particle size distribution
                         widens  and the number of droplets  of small diameter in-
                         creases, efficiency improves; 3) the volumetric coefficient for
                         gas absorption shows a similar tendency as the washing factor
                         for diffusiona! collection; 4) as the relative velocity between
                         droplets and  gas stream increases, the effective gas film
                         becomes thinner and the diffusional collection efficiency in-
                         creases.

                         reviewed.  Electric dust collecting devices for cement kilns are
                         said to be  over 98.5% efficient. Six different types of  rotary
                         kiln (used  mainly in Japan) and different types of dryers are il-
                         lustrated.  The main  dust collecting devices are electrostatic
                         collector (for kiln and dryer):  multiclone  (for cooler, ventila-
                         tor, or  dryer);  starclone (for rapid dryer);  cyclone (for coal
                         dryer); wet system (for  dryer); Venturi scrubber (for  dryer);
                         and bag filter (for crusher, conveyor, or wrapper). Some larger
                         factories in Japan are restricted by law as to SO3 and SO2
                         content  in the exhaust gas (22% of SO2 and SO3 per 1 gram of
                         soot). The analysis of exhaust gas from a  cement factory is
                         given; particle size distribution of cement dust  and a chemical
                         analysis of collected dust are also given. Exhaust gas frftn ce-
                         ment factories generally does  not exceed the legal limit for
                         SO2  and SO3.  Studies  have  shown that cement dust  is not
                         harmful to animals or plants, but  efforts to  minimize dust fall
                         are continuing.

Desulfurization of crude oil and heavy  petroleum  residues is
reviewed. Numerous types of sulfur compounds contained in
the residue of heavy petroleum distillation and their reactions
are discussed in terms of the hydrogen consumption for desul-
furization of the residue. Representative  catalysts proposed for
desulfurization by hydrogenation are tabulated. Vanadium will
reduce the activation rate of catalysts.  Selection of the most
effective catalysts for a given oil  or residue depends on  the
desulfurization process employed. Six commercial desulfuriza-
tion processes are illustrated and explained.

Measurements conducted  on  a series of commercial cyclones
confirm, in principle, the method  of  calculation proposed by
W. Barth. The new curves for the  degree of fractional separa-
tions vary considerably according to the construction of  the
separator, whereas it was formerly customary to use a single
curve. Measurements at high  loads have made possible an ex-
tension  of the theory, by  means of which the performance of
normal  cynes may now be calculated with good  accuracy
for all  possible loadings. The  operating parameters of  the
cyclones are explored mathematically and graphed.

ELECTRIC CLEANING OF WASTE GASES FROM CARBON
ELECTRODE BAKING FURNACES.  ((Elektrische Reinigung
der Abgase aus Elektrodenbrennofen.))  Text in German. Alu-
minium  43(3):171-174, March 1967.
Waste  gases  from carbon electrode baking furnaces contain
extremely fine tar vapors with a  range of boiling  temperatures.
These vapors can be precipitated most effectively by means of
electrofilters. The gases in many cases must be cooled before
tar vapor removal, due  to the differences in boiling  tempera-
tures; if this step were not  taken, the amount of tar vapor
reaching the atmosphere would still be too high despite the fil-
ter's efficiency. The industrial application of the electrostatic
precipitation gas cleaning process is described and illustrated.

NEW REFINERY IN THE SAAR.  ((Die Saarland-Raffinerie.))
Text in  German. Erdoel Kohle (Hamburg), 21(6):331-334, June
1968.
Prevention of water and air  pollution is one of the subjects
discussed briefly in a detailed description of the new refinery
erected  in 1967 near Saarbrucken,  German. The refinert is a
top-distillation plant with a capacity of 2 million tons per year,
producing  straight-run gasoline,  light  and  heavy  fuel oils,
diesel oil, and refinery gas. In order to protect  the neighbor-
hood, the smoke from the  tubular still (which has a capacity of
30 million kcal./hr.)  is voided through  a 90-meter stack,  the
height being calculated on the basis of the use  of fuel oil with
a sulfur content of 2.5%;  in actual practice, the fuel oil used
contains less sulfur, and  gas  from the stabilizing column is
also used as fuel  for the furnace.  Escape of hydrocarbons is
prevented by connecting the  safety valves  of  the  still to  the
discharge or torch system of  the  furnace.  The  more volatile
products are  stored  in tanks with  floating roofs.  The waste
water is also treated to remove volatile compounds, which are
burned in the furnace, and is then led to a closed API separat-
ing tank.

EXPERIMENTS IN THE USE OF WHITE  LIME HYDRATE
AND  DOLOMITE LIME TO DESULFURIZE FLUE GASES
FROM OIL-AND PULVERIZED COAL-FIRED  FURNACES.

hydrat  und  Dolomitkalkhydrat  bei  Oel-und  Kohlenstaub-

The   suitability  of  white lime  hydrate and  dolomite  lime
hydrate to  desulfurize flue gases was tested by mixing the ad-
ditives with pulverized coal by injecting them  into the  com-
bustion chamber above the burner of a furnace heated with
pulverized  coal and oil. The experiments confirmed theoretical
predictions that, due to the short residence  time of flue gases
and  additives in a furnace,  complete desulfurization is not
feasible. Direct mixing of coal and additive caused formation
of eutectic melts during combustion, leading to heavy caking
of the furnace.  Only small  amounts  of sulfur dioxide  were
bound by additive surfaces. A higher desulfurization rate was
achieved by injecting the additive into the zone of the furnace
where temperatures of about 1000 C prevailed.  White lime
hydrate  was more  satisfactory  than  dolomite  lime hydrate,
since the additive contains fewer impurities and  the decom-
position  pressures of calcium sulfate  are  lower  at constant
temperature than those of magnesium  sulfate. The best desul-
furization results were obtained with oil-firing. Here, the  addi-
tive  depositions  on  the rear heating surfaces continue to bind
S02  and are  the  major factors  in the totally achieved desul-
furization rate. Despite this, only 50% of the S02 was bound.

CLEAN AIR.  (Chistii vozduh.) Text in Russian. NTO-SSSR.,
10(12):17-18, 1968.
In 1967 power plants in the Soviet Union emitted about 7 mil-
lion tons of SO2. SO2  removal from combustion gases is car-
ried  out in four ways:  1) Dispersion by means  of high chim-
neys; this  approach is being studied in the Central  Ther-
motechnological Institute, Main Geophysical Observatory, and
in the Erisman Institute of Communal  Hygiene. A formula for
calculating  the waste in relation to location, topography, and
climatic  conditions  has been established; this approach was
recognized  as promising only  for power plants with capacities
up  to 2400 megawatts. 2) Preliminary  sulfur removal  from
fuels has  been  little  studied.  3) Gasification  process  of
Christianovich in VNIINP and  Giprogazoochistka has  been
patented. 4)  Processes for SO2 removal in solid fuel  com-
bustion were presented by V. Lazarev and N. Pitelina. The
most promising, according to economic indexes, are the cyclic
magnesite  and ammonia-autoclave methods,  which give 95-
95%,  and 92% removal rates, respectively. The  advantages of
the former are that it uses the cheap  magnesite and does not
require cooling and  dust- removal; the  advantages of the latter
are the formation of high- purity sulfur and the fertilizer, am-
monium  sulfate.  The disadvantages of the cyclic magnesite
method are difficulties in working with the suspension, high
fuel  consumption, and  burning of  magnesium sulfite crystals.
The  disadvantages of the ammonia- autoclave method are the
high ammonia consumption and  the necessity for preliminary
dust-removal.  The SO2 formed  in the  petroleum refining  is

revoved by the Klaus method or the method of wet catalyzer
to sulfuric acid. There are more than 20 methods for industrial
H2S removal  from gases.  Most methods  have the aim  of
technological exploitation of the removal H2S and are not
suitable for sanitary purification. For the latter purpose the
best are the oxidation methods which use adsorption of H2S
to alkaline  solutions (soda or ammonia) and oxidation to ele-
mental S by a catalyzer. The oldest, iron-soda method, has
many disadvantages (long duration, detrimental effect on the
equipment, poor  gas  purification) and is to be replaced  in
U.S.S.R.  plants manufacturing synthetic fibers, by  an alkali-
hydroquinone method. Its advantages are: absence of suspen-
sion, simpler procedure of exploitation, and yield of high-puri-
ty sulfur. The method of dry oxidation with activated coal  by
which H2S is oxidized to elemental S has the  advantage that
the coal  functioning as catalyzer  and adsorber can remove
H2S,  CS2,  and  other  impurities.  Hydrocarbons  and  their
products, which are important air pollutants from the petrole-
um industry, can be

Since conventional methods of  purifying gases from finely
dispersed dust cannot be applied at temperatures above 600 C,
the use of laminar filters has been suggested. These filters
consist of granules of fire-resistant materials. As indicated  by
preliminary experiments, separation of dust from a gas stream
by  such  a  filter  corresponds  to filtration with  a gradual
plugging of the pores of the filtration  partition during the pu-
rification of liquids where the concentration of solid particles
is low. The process was studied only for cases where the  pres-
sure difference on both sides of the partition  remained  con-
stant during filtration. Separation of dust from a gas stream  by
a laminar filter is carried out at constant flow velocity. In the
present study, an equation  was derived to describe filtration
with a gradual plugging of the pores of the filtering partition at
a constant flow velocity.  Separation  of  particles  below  1.5
micron from smelter dust corresponds to  such filtration. An
expression  was also obtained for expressing  the correlation
between filter efficiency and its hydraulic resistance.

COUNTERMEASURES TO  AUTOMOBILE EXHAUST GAS.
Taiki Osen Kenkyu (J. Japan Soc. Air Pollution), 1(1):13-17,
1966. Translated from Japanese. 24p.
Measures to stem automobile exhaust gas emissions enacted in
Japan,  the U. S., and in Europe are discussed. Japan had
about 8 million automobiles at the end of May 1966. Since
1965, the Ministry of Transportation has enforced measures to
stem emissions by automobiles. All new models of cars  must
undergo a standarized  test to determine whether the maximum
allowable emission concentrations are exceeded. The following
driving conditions are  simulated  on a dynamometer: idling;
cruising at speeds from 10 km/hr  to 70 km/hr in intervals  of 10
km/hr; acceleration from 0 speed wherein  the rate of accelera-
tion  is 0.1 g and the final speed is reached in five  steps
beginning  at 30  km/hr;  and deceleration by engine braking,
wherein the rate is 0.06 g. The measures taken to stem exhaust
gas emissions consist of engine modifications such as improve-
                         ment of the air-fuel ratio, the air intake, the ignition time, the
                         combustion chamber,  and the  valve timing; remodelling the
                         muffler into a direct flame afterburner or a catalytic converter;
                         and addition of chemicals to the fuel. A method is under con-
                         sideration by which oxygen is mixed with the gasoline so that
                         incombustible matter is oxidized in the combustion chamber.
                         Presently studies are under way primarily in the U. S. to inject
                         air into  the exhausts. Studies in Europe concentrate on the
                         elimination  of carbon monoxide emissions  and on   diesel
                         smoke. Japan also focuses  its  attention  on elimination or at
                         least reduction of the carbon monoxide fraction in automobile
                         exhaust.

                         A novel copper  refining  method,  using "The  Auto-blast fur-
                         nace' developed in Finland, is becoming predominant in  Japan.
                         It has three notable advantages:  0) easy re-absorption of SO2
                         by means of compressed flue gas; (2) low cost, because of less
                         investment  for the  facilities and equipment for  pollution
                         prevention; and  (3)  production  of more  by-product H2SO4.
                         The refining process can be briefly summarized as follows: (1)
                         preliminary process, in which the minerals are dried; (2) melt-
                         ing  and  refining;  and (3) handling of flue gas. A significant
                         aspect of this method is that controlling the temperature and
                         pressure within the furnace and cyclone enables almost perfect
                         re- absorption of SO2 emitted and production  of a considera-
                         ble amount of H2SO4.

Diesel oil  have low sulfur contents and are  of better quality
than the primary products. The harmful effect  of  ammonia,
which originates  from the nitrogen-containing substances, can
be  eliminated by elevating the  temperature.  It  has  been

19(3):140-142, 1969. 5 refs.
When the daily production of sulfuric acid ranged to 100 t/day,
with 95 to 97% conversion and with an average  absorption of
99%, even with relatively low chimney heights, the immediate
vicinity  of factory was free from emissions. When production
exceeded  300 t/day, higher  chimneys  did  not sufficiently
reduce  the  local concentrations.  In most plants  using the
heterogeneous oxidation  manufacturing method, SO2  emis-
sions  are 0.2  to 0.4%, SO3 emissions are 0.02  to 0.1%, and
H2SO4  emissions are 0.075%. For the work in Prerov, which
produces 100,000 t/year,  a two- stage exothermic process of
catalytic oxidation of SO2 was adopted.  Output is higher than
103,000 t/year, and 10 kg  of sulfur are recovered for 1 t of the
manufactured sulfuric acid. The process uses a  closed circuit
of cooling  water which requires 20% more  water  than with
traditional methods,  and  3.5 kWh/t more  sulfuric  acid,, and
which produces  10 kg less of steam per ton of  sulfuric acid.
The cost of the absorption equipment is offset by the value of
the sulfur  recovered.  The greatest advantage of  the unit is its
reduction of harmful  emissions.

An oxidation tower system for reducing odorous compounds
formed  during alkaline pulping was developed by the British
Columbia  Research  Council and  installed  at AB  Morrums
Bruk, Morrum, Sweden, where its efficiency was investigated.
The system involves the pumping of black liquor through the
oxidation tower in the same direction as a gas mixture contain-
ing air, uncondensed gases  from  the turpentine recovery, and
gases from  the digester blow.  After leaving the  oxidation
tower, the mixture is washed with chlorine and dilute sodium
hydroxide in a scrubber  before being  vented into  the  at-
mosphere. Gas  chromatographic  determination of the  amount
of methyl  mercaptan,  dimethyl  monosulfide, and dimethyl
disulfide in  the gas mixture before and after it had passed
through the  tower and  scrubber  reveals  that  the  system
removes more than 99% of the methylsulfides and more than
97% of the mercaptans. The greater part of these compounds
is taken up by the black liquor  in the oxidation tower;  the rest
is oxidized in the scrubber. The concentration of the odorous
compounds in the outlet from the  scrubber  is very low and
their smell can  be characterized  as 'faint'. About 90% of the
sodium sulfide in the black liquor is oxidized in the oxidation
tower. (Author abstract modified)

THE NEW WASTE GAS DESULFURIZATION METHOD OF
THE   GRILLO   WERKE   AG.     (Das  neue   Abgas-
Entschwefelungverfahren der Grillo-Werke AG.) Text in Ger-
man.  Erzbergbau  Metallhuettenwesen, 21(12):567-571,  Dec.
1968.
There are three methods for desulfurizing waste gases; first by
oxidation of SO2 to SO3 on vanadium catalysts, secondly by
adsorption of gaseous sulfur compounds on activated coal or
coke, and thirdly by absorption, i.e., chemical binding of acid
components in  the waste gas by  alkaline substances. Detailed
discussion of the latter method shows that in all cases where
this principle has been put into  practical use, costs ran tremen-
dously high, primarily because of the complicated regeneration
and  recovery  operations for  the  absorbent  and the sulfur
bound by it. The Grille Werke AG, in developing its absorp-
tion method, tried to make it as  economical as possible, and
although the present method is not the definitive solution, it
does provide some advantages over other methods. The Grille
method is based on the principle of formation of oxide com-
pounds between an alkaline and an amphoteric heavy metal
component. Thus, the  two components mutually prevent each
other from being inactivated by the temperatures necessary for
thermal regeneration.  In  this  way, both sulfur dioxide and
hydrogen sulfide can be bound. Manganese and magnesium are
used as elements for the formation of oxide compounds. Ex-
periments in a  large-scale plant showed that between 80 and
95% of  the  SO2  of   a  waste gas could  be removed. In-
terestingly, the  degree of loading of the absorbent suspension
played a secondary role. The absorbent which is tapped off in
dry state contained between 17 and  21% sulfur, which justifies
recovery operations. Any sulfuric acid factory in the  vicinity
can be used for this purpose. A detailed description of the ex-
periments is given, as well as an  example of practical applica-
tion of the Grillo absorption method.

dehydration to avoid emission of volatile organic sludge com-
ponents with the waste gas and to permit  autonomous com-
bustion. To achieve the latter goal, the combustion tempera-
ture must be high, the excess air in the reaction chamber low,
the incineration complete, and the temperatures of the waste
gases and vapors low. However, the waste gas temperature
may not drop below 750 C if odors are to  be  avoided and if
the residues ought  to  be sterile. To solve the problem, the
fluidized bed furnace must be used. The sludge  falls into a bed
of turbulent sand particles where it is dried, degassed, and ig-
nited. The  temperature of the  waste gas  at the  combustion
chamber outlet is 800 to 900 C. It is cooled in an air preheater
and the heat is returned to the combustion chamber. In the
subsequent dust collector, the mineral sludge components are
separated as dust either by a wet or dry process and tapped
off to an ash pit.  The  turbulent sand particles are slowly
eroded and  carried  off with the ash.  They are replaced by
larger ash  particles  and  by sand brought  in  by  the  sewage
sludge. The furnace has  no movable  parts aside from the
charging  facility and the ventilators so  that  wear and tear are
low. The city of Lausanne has  operated such a fluidized bed
furnace since 196S.  The furnace burns  2600 kg of dehydrated
sludge per hour (max.  water content 60%).  Part of the waste
gas is used to heat  the combustion air  and  the rest goes to a
boiler. The waste gases are cleaned in cyclone  separators and
electrostatic precipitators.

ESTIMATION  OF  COLLECTION  EFFICIENCY   OF   A
DIELECTRIC FIBROUS FILTER.  (Yuden seniso fuiruta no
hoshu  koritsu  no suitei). Text  in Japanese. Kagaku  Kogaku
(Chem. Eng.), 33(7):684-689, July 1969. 10 refs.
Inertia, scattering, and interference are three mechanisms af-
fecting the collection of particles in a fibrous filter. Inertia is
the dominant factor when both linear speed and  diameter of
particles  are large;  scattering  is dominant  when  both linear
speed and  diameter of particles are small; and interference,
which minimizes collection efficiency, is dominant when it oc-
curs between inertia and scattering. By the  use of a dielectric
fibrous filter, collection efficiency is remarkably unproved and
interference is  reduced.  The dielectric fibrous filter retains
both bipolar cylinders  and bipolar particles within the same
electric field; polluted  air passes vertically through this filter.
The volume fraction of fibers is less than 0.02, and there is a
constant relation  between the coefficient of interference and
the volume fraction. Both collection efficiency of a single fiber
in a dielectric fibrous filter and total collection efficiency can
be calculated, and thus the collection efficiency can be con-
trolled by changing factors in the equation. High collection ef-
ficiency is  achieved with only a small loss  of air  pressure in-
side the filter.

ECONOMICAL  STATUS FOR  RECOVERING  SO2  FROM
STACK  GASES.   (Haien datsuryu no keizaisei).  Text  in

Both  direct and  indirect desulfurization of crude petroleum
require expensive equipment,   and neither method removes
more  than  15% of the  total sulfur from the petroleum. Desul-
furization of stack gases is more economical, and studies on it
have multiplied in recent years. Desulfurization techniques in-
vestigated by the Tennessee Valley Authority since  1952 in-
clude activated  carbon  adsorption,  catalytic  oxidation, the
                         manganese dioxide process, alkaline absorption with ammonia,
                         alkalized aluminum, and limestone. The results of TVA's stu-
                         dies of  desulfurization with limestone  show  that 50 to 60%
                         removal of sulfur dioxide from crude petroleum is obtained by
                         injecting stack gases with dried limestone and that adsorptive
                         potency is related to the roughness of the limestone. This dry
                         process  does not need  expensive equipment and  has other
                         practical advantages.  The  wet process  using  limewater
                         removes more than  85% of sulfur dioxide, but has two disad-
                         vantages namely, the drop of exhaust gas temperature at the
                         chimney exit and lime  deposits on the interior surfaces  of
                         equipment. The latter problem can be solved by placing a tur-
                         bulent floor inside the equipment. To meet the shortage of sul-
                         fur and  sulfuric  compounds, several techniques utilizing SO2
                         as a source of sulfur have been devised which use ammonium
                         or potassium phosphate to good advantage.

                         About 90% of the petroleum used in Japan has a high average
                         sulfuric   compound  concentration of  2.7%.  Desulfurization
                         removes sulfur, H2S,  and   SO2.  This paper  concerns
                         hydrogenized desulfurization which requires excellent  materi-
                         als and techniques appropriate to high temperature, high pres-
                         sure, and high concentration of sulfuric compounds. The direct
                         desulfurization of the crude petroleum at normal pressure has
                         a high  desulfurization ratio, although the  temperature, pres-
                         sure, and concentration of hydrogen and H2S  are significantly
                         high. Thick stainless steel is not only expensive but also very
                         sensitive to corrosion by sulfuration. The severity of corrosion
                         of alloy  steel and stainless steel caused by H2S with hydrogen
                         in the dry  procedure is  significantly increased  with  the in-
                         crease of H2S concentration and temperature,  and is markedly
                         decreased with the  increasing amount of Cr within the alloy.
                         In the wet procedure, however, the corrosion caused  by H2S
                         and hydrogen is  much more severe than hi the dry procedure.
                         In order to avoid corrosive cracking, the use of adequate al-
                         loys, including  double-layered  steel,  and/or procedures  to
                         remove  sulfuric  compounds during the time of cooling the
                         equipment are being  explored  with increasing  success. The
                         vessel walls  supported by  multiple cold layers and  internal
                         fire-proof lining resist high  temperature, high pressure, and
                         high concentration of  H2S. The conducting tubes which con-
                         nect one vessel to another also need high tolerance against the
                         pressure and corrosive effect of H2S,  especially at the con-
                         necting  portion.  A fireproof cast iron alloy, HP, and an im-
                         proved type HF, which includes 5 to 15% of delta-fernte, are
                         cheap and corrosion-  resistant. Aluminum-containing steel is
                         excellent as  an alloy coverage because  it is very stable in the
                         presence of high temperature, high pressure, and high concen-
                         tration of sulfuric compounds.

The possible usefulness of calcium carbonate as an absorber
of SQ2, and SOS  is supported by data from a thermographic
analysis of the system CaCO3(CaO) - SO2(SO3) - air. Sulfur
dioxide in  an oxidizing atmosphere reacts  energetically with
calcium oxide  produced by  decomposition of calcium car-
bonate and limestone, calcium sulfate  being formed through a
sulfitation step. Calcium sulfite is the basic product at 300-500
C, calcium sulfate at higher temperatures (up to 1000 C). Cal-
cium sulfate may  also be formed through oxidation of SO2 to
SO3 and reaction of the latter with oxygen and calcium car-
bonate. These chemical mechanisms are of importance in the
lime method of removing SO2 from posver  station flue gases.
Data both from the literature and from new §xperimental work
were used in the study.

The rate of oxidation of calcium sulfite  formed in the extrac-
tion of SO2 from  exhaust gases was found to average 9.4 g/sq
m-hr with an average oxygen  absorption coefficient of 72 g/sq
m-hr-atm for the  test absorber. The degree of  oxidation was
found to result from the simultaneous effect  of a number of
factors  influencing  mass  transfer  in  the liquid phase (e.g.,
reflux  density, temperature,  and composition of reflux solu-
tion).   It  was found  that  addition  of  0.002-0.004%  P-
aminophenol to the circulating solution has a long-term retard-
ing effect on calcium sulfite oxidation  and results in a three to
five-fold decrease in sulfate formation.

AIR POLLUTION IN THE LACQ COMPLEX.  (La pollution
atmospherique  dans  le  complexe de  Lacq). Text in French.
Pollut. Atmos. (Paris), ll(42):71-73, April-June 1969.
A history of the progressive  industrialization  of the Lacq re-
gion is presented.  Most of the .pollution in this region is caused
by the SO2 given off by the Societe Nationale des Petroles
d'Aquitaine (S. N. P.  A.). It was found  that natural gas treat-
ment does  not totally eliminate SO2. The S. N. P. A. and the
Lurgi-Waerme  Company  from Frankfurt have developed  a
new  process called 'Sulfreen' which  reduces  the amount of
sulfur compounds emitted into the atmosphere. The first unit
will treat 130,000 cu nm/hr of gas. The principle of the process
is as follows: One of the two reactors is in contact with the
gases  coming from the two primary converters of the  sulfur
plant at 125-130 C. Its catalyst becomes  increasingly burdened
with  sulfur while  the second reactor is being regenerated by a
closed-circuit flow of gas which has been heated in a furnace.
The deposited  sulfur is vaporized by the  hot gas  and con-
densed in the condenser where the gas is cooled. A ventilator
completes the circuit.

REMOVAL OF SO2  GAS IN EXHAUST «AS BY STEAM-
GENERATED  ACTIVATED  CHARCOAL  PROCESS  (HI)
DESORPTION  OF SO2 GAS BY STEAM.  Translated from
Japanese. Hitachi Shipbuilding Co. (Japan), p. 1422, (1968).
Since  the  absorption  capacity of activated  charcoal  drops
gradually as it absorbs a greater volume  of sulfur dioxide gas,
the charcoal must be regenerated by desorbing the S02 from
it. For this purpose the Reinluft process uses high temperature
inert gases and, in large projects, rinsing. This paper describes
an attempt to obtain the same results by using superheated
steam at  about  300 degrees C. The interrelation is  shown
between the condition  of absorption and the  weight or com-
position of the absorbed gas.

German. Silikat Tech., 20(5): 148-155, 1969. 23 refs.
The  four  alkali   earth   carbonates   (CaCO3,   travertine,
limestone, and ddomite) were studied with respect to their ad-
sorption of  sulfur dioxide  and water vapor using gas chro-
matography. It was found that CaCO3 dried at  180 C  at first
adsorbs considerable quantities of SO2 from a SO2- and CO2-
containing gas. The SO2 adsorption isotherms  found  by the
frontal gas chromatographic process of G. Schay all belonged
to type I of Brunauer's classification. Water vapor adsorption
of all four carbonates was determined at 20, 40,  60, and 80 C.
The water vapor adsorption isotherms were found to belong to
type II of Brunauer's classification. Studies by  the gas chro-
matographic pulsed flow method showed that SO2 adsorption
by the system CaCO3-SO2-H2O at temperatures ranging from
0 to 100 C occurs at relative water vapor partial pressures of
almost 1.0. Chemical conversion of SO2 to calcium sulfite oc-
curs at partial pressures down to zero. This leads  to the con-
clusion  that formation of  the  adsorbed  water  vapor into  a
three dimensional  fluid at the absorbent surface is a more
thorough  process than all  known  theories concerning water
vapor adsorption on solids have anticipated. A critical relative
water vapor partial pressure for calcium sulfate formation was
found at  0.50, above which higher chemical  activity  occurs.
Calcium sulfite (at oxidation) or calcium sulfate  solidifies  cal-
cium carbonate dust and changes its  surface properties. Cloth
filters and electrostatic  precipitators are thus hampered  in their
function. Five known types of waste gas of desuftiirfzation are
discussed.

Aeromechanical and wet separators are considered in terms of
their  dust  collecting  efficiencies  for  metallurgical   and
technological processes involving the use of oxygen. Previous
dry aeromechanical separators had relatively low efficiency
and  did   not  meet  hygienic  requirements. Wet  separators
reached acceptable levels of separation, but their tendency to
become clogged with sediment limited their usefulness. A new
aeromechanical separator processes dust in agglomerations at
an efficiency level of 95%; the diameter of this apparatus is
630 mm.  A new venturi-type  separator of rectangular cross
sections separates  micron and  submicron particles from  the
brown smoke  produced in metallurgical processes. Extremely
good results were  obtained when  this  scrubber was used to
treat combustion products from open and double  hearth fur-
naces in pilot plant operations.

INDUSTRIAL WASTE  INCINERATION  BY  FLUIDIZING
SYSTEM.  (Sangyo haikibutsu no ryudoshokyakuho). Text in
Japanese. Kogai to Taisaku (J. Pollution Control), 5(7):529-533,
July 1969.
Fluidizing systems, which are widely applied to petroleum and
mineral  combustion,  are  highly  efficient. The  outstanding
merits of this system are a capacity  of 500 kg/cu  m-hr in-
cineration;  the ability to incinerate low-calorie wastes (1000/k-
cal/kg, water 70%) without catalysts; perfect combustion with
kiln heat around  750  C; no stack smoke  or odor problems;
simplicity of  structure, with no vibrations  inside the kiln and
constant and stable internal heat; availability of electric power,
produced though the process in large-scale  (400 t/day) kilns of
this system; convenient operation requiring no heavy or inten-
sive labor;  and economical maintenance.  The  system has a
wide range  of applications, including waste incineration in the
chemical, food processing, and petroleum  industries, and  ex-
crement and sludge treatment. For example, the liquid wastes
from  paper manufacturing plants  that used to be discharged
into rivers,  bays, or seas and caused problems for agriculture,
fishing, and shipping may now be incinerated, removing all the
organic matter contained in pulp  wastes, and chemical com-
pounds such  as Na2SO4 or Na2CO3  may be recovered and
reused in kraft pulp production. Adaptation of this system to
watery wastes in the food and  chemical industries has the ad-
vantages  of deodorizing wastes and recovering ash for use as
fertilizer. The  system  can  be  adapted  to petroleum and
petrochemical wastes and to high-temperature wastes.

Munkavedelem, 14(4-6):l-4, 1968. 18 refs.
According  to Hungarian industrial health standards,  the max-
imum permissible  hydrogen sulfide concentration in workshops
is 10 mg/cu m. Catalytic reforming and fuel oil desulfurization
processes in the Petrochemical Works of Komarom produced
(after ethaholamine extraction) a flow of 220-650 kg/hr; 98% of
the  gas  was pure  H2S, and  only  2% was H2O  or light
hydrocarbons. To  remove H2S, economic studies  suggested
the  use of absorption methods giving Na2S  as the end product.
The process first involves obtaining 72% concentrated NaOH-
H2O solution from a 45% starting solution in a vacuum still, at
80-90  C.  Then the gas mixture  containing H2S will be reacted
with  the NaOH  solution; the  Na2S  crystals  produced  are
distilled in  one or two steps depending on their water content.
The remaining gas  is  transferred from the reactor  vessel to
cadmium acetate  washers where the unreacted  H2S is  ab-
sorbed. The NaOH concentration will control the reagent con-
tent of the  developing Na2S; the NaOH concentration may be
controlled by temperature and pressure regulation. No further
cleaning of  the Na2S is necessary.

                        There are only 18 cement works in Switzerland with relatively
                        small capacities and only one kiln producing more than 1000
                        tons per day. Since 1950, this industry made great strides in air
                        pollution control.  The Swiss  Association of Cement,  Lime,
                        and Gypsum  Producers established their own rules for dust
                        emissions in  1963  which were  binding for members.  Clean
                        gases from new installations should not have more than  75-100
                        mg dust/cu m.  Older plants have until 1973 to reduce their
                        emissions to 100-150 mg dust/cu m. A  federal law states that
                        only  plants which  meet these requirements  obtain approval
                        from the Authorities of the Canton. In all cement works meet-
                        ing the emission standards, adequate dust  collection devices
                        are in operation. The sources of dust in the cement works,
                        adequate dust collection equipment, and costs were discussed.
                        Equipment includes bag filters for dry dust and gases at low
                        temperatures, electrical precipitators for the cleaning of waste
                        gases from kilns, and raw material dryers. Installation difficul-
                        ties from corrosion and methods for  the  correction of the
                        problem were described. Multicyclones and gravel bed  filters
                        also  have special  applications  in the  dedusting  of  clinker
                        coolers.  It was concluded that many Swiss  cement works are

                        The waste  acidic  substances derived  from  the  purification
                        system  of crude petroleum refineries includes  a  great many
                        sulfur compounds and can be utilized  to manufacture  sulfur
                        dioxide gas by the  following two procedures. First, the waste
                        substance is  added  to a calcium sulfite (CaSO3) solution caus-
                        ing formation of SO2 gas as well as H2S, mercaptans, and  or-
                        ganic sulfur compounds. The CaSO3  used in this procedure is
                        obtained at low cost by the absorption of SO2 waste gas from
                        other refineries by alkaline calcium  compounds also derived
                        from other  industries.  The plaster produced by  the first
                        procedure is utilized for the manufacture of cement or nickel
                        mat. Secondly, a mixed gas including several kinds of volatile
                        sulfur compounds is heated within the hearth at 600 C to form
                        SO2  gas.  This  is  a  convenient and  economical means  of
                        producing SO2  from the waste  substances of the petroleum
                        refinery.

                        The invention relates to the desulfurization of the broad cut
                        portion of crude oil by  hydrogenation.  The broad cut portion
                        contains naphtha, kerosine, etc. as single cuts. The crude oil is
                        heated until  all  the broad cut pan evaporates and is distilled
                        by flash evaporation under the pressure of 30 psi. The vapor is
                        condensed and  cooled to  a temperature lower than  200 F.
                        After removal of the uncondensed gas, the liquid  is heated at
                        100 to 1000 psi  and then at pressures high enough for all con-
                        tents to  evaporate. Hydrogen gas is added, and the broad cut
                        portion  desuifurized in the  presence of a catalyst such as

hydrogen sulfide generated is washed away by an amine solu-
tion such as dimethylamine or diethylamine. A narrow boiling
point oil is obtained by the fractional distillation at about 60
psi. Application of this method to crude oil containing 1.9%
sulfur decreased  the sulfur content of  kerosine to 0.0004%,
and that of light straight naphtha to 0.0002%.

Effective gas purification  measures at the Kramatorsk  Metal-
lurgy Plant and at the Zaporozhstal Martensite Furnace No. 2
are also reported. Failures at pollution control  have  occurred
at some locations, especially in the Donbass, because the ac-
tual efficiency  of control equipment has  been  significantly
below  the  design values,  or  else already  existing  pollution
sources were not adequately accounted for.

An isothermal model was applied to the study of the flame and
waste gas aerodynamics in the open-hearth furnace. The flow
was studied by measuring the selected sections with the help
of a pneumatic probe provided  with three  holes. The  tests
revealed that the furnace  was operated with the atomizing air
volume adjusted wrongly, which resulted  in the  insufficient
momentum of the oil burner. Corrections were suggested and
were  checked  in  the  model tests. Theywere  then put into
operation.  As a result, the heat time was cut and the furnace
output was increased. (Author abstract modified)

Experiments  were conducted on  the  decontamination  of ex-
haust  gases  in  sulfate-cellulose  production  by the  foam
method, based on the interaction of a gas and liquid in a layer
of moveable  foam formed as a result of their counterflow.  It
involves the purification of gases  from the plant furnace, con-
centrator, and boiler units. When the gas flow rate of the foam
device was varied from 0.4 to 3.2 m/sec, the purification of
furnace gases was constant and amounted 92-95% (based on
total sulfur). After purification, 10-40 mg/cu Mm hydrogen sul-
fide, 8-46 mg/cu Nm methyl mercaptans, and 3-120 mg/cu Mm
sulfur  dioxide  were present in furnace flue  gases.  Decon-
tamination of the boiler gases removed 92% of the hydrogen
sulfide, 90.7% of the methyl mercaptans, and 86.0% of the sul-
fur dioxide. When  the  simultaneous decontamination of ex-
haust gases from furnace, concentrator, and  boiler sections
was  studied,  using caustic soda as a wetting liquid, 92.3% of
the hydrogen sulfide, 84.7% of the methyl mercaptans, 86.6%
of the dimethyl disulfide, 72.8% of the dimethyl sulfide, and
89.9% of the  sulfur  dioxide were trapped. When black lye was
used as the wetting agent in an oxidation tower, no odor of
sulfur-laden gases was detectable.

The oxidation of SO2 in the presence of  iron ion was studied
experimentally.  The following  optimum  conditions  were
established for  simultaneous processing  of  waste gases and
pickling solutions: 1) during oxidation of FeSO4 to Fe2(SO4)3
- temperature from  60-80 C, incoming SO2:O2  ratio of 1:5, an
initial concentration of ferrous sulfate up to  18% does not af-
fect the course of the reaction; 2) during sulfuric acid forma-
tion -  temperature from 80-90 C, SO2:O2 ratio equal to 1:4,
optimum iron ion concentration, 10-30 g/liter. An acid forma-
tion rate of about 1000 kg of sulfuric acid monohydrate from a
cubic meter of reaction  volume was achieved in the laboratory
under optimum conditions. These experiments demonstrate the
advisability of examining the reaction of SO2 exhaust gas with
spent pickling solutions  under plant conditions for the purpose
of recovering the pickling solutions or for producing dilute sul-
furic acid and crystalline ferric sulfate.

The following fuel oil desulfurizing plants are under construc-
tion or in the planning stage: H-oil unit of 24,000 barrels/day
at Shinoiba, Kuwait; an Isomax plant, 35,000 b/d at Mina Ab-
dullah, Kuwait; and an Isomax plant, 40,000  b/d in Chiba,
Japan. The economic problem of providing low-sulfur fuel oil
in Europe differs from that of the United States in that there
is a greater demand for gasoline and medium-to-light distillates
and  a higher  demand for heating oils, a condition to be even-
tually  offset  by  increasing demands  for light  petroleum
products in petrochemistry, increased use of motor vehicles,
and  greater availability of natural gas. Future projects  call for
preliminary gasification  under pressure, which  can  lead to the
formation of  hydrogen sulfide gas. Hydrogen sulfide liberated
from the gasified fuel is more easily  captured than SO2 in the
exhaust gases,  and  lends itself more readily to the manufac-
ture of elemental sulfur to be sold as a by-product. Gasifica-
tion provides a fuel gas that can be highly varied in composi-
tion, with almost no additional expenditure of power. By mak-
ing use of the chemical and physical enthalpies of these gases,
the yield of the  modern heating plant can be raised by 5-15%,
plus compensations  from the sale of by-products.

Air-pollution control in England is  based on the Alkali and
Works  Regulation Acts and the Clean Air Act. The country is
divided into seven Alkali Inspectors' Districts administered  by
25 inspectors who maintain close contact with local health and
smoke  inspectors. The  annual reports compiled by the inspec-
tors form the  basis of the Manual  Reports  submitted to the
Ministry  of Housing and Local Government. These reports
contain the air pollution plans and policies currently in  prac-
tice. The contents  of the  Manual Report  of  1960, 1964, and
1965 are  summarized. Though England does not have a prima-
ry aluminum refining industry, it has aluminum manufacturing
industries which mainly treat aluminum scraps. Air pollution
problems due  to aluminum manufacturing, and  countermea-
sures, are discussed in the 1960 Manual Report. A number of
plants  found   venturi scrubbers  unsatisfactory  for reducing
smoke  emissions. Better results were obtained by rinsing the
aluminum scrap and discharging smoke from taller stacks. The
1964 Manual Report shows that the problem of an oily smoke
was partly solved by afterburners and that  of fumes solved  by
employing  hearth furnaces (flat  type)  which do  not require
flux. The reports  emphasize  the cooperation between  legal
authorities  and industry. This approach  to  practical control
measures has  implications for countries which are  trying to
control air pollution by legal means alone.

PRESENT  STATUS AND FUTURE PROSPECTS OF AUTO
EXHAUST  CONTROL.  (Jidosha haishutsu gasu taisaku  no
genjo to  doko). Text in Japanese. Kogai to Taisaku  (J. Pollu-
tion Control), 4(7):405-409, July 15, 1968. 3  refs.
In Japan, some  progress in controlling auto  engine exhausts
has been realized as the result of control measures introduced
in 1966. For example, despite increasing traffic, there has been
a decrease in the CO detected at  intersections due to improve-
ments  in the  road  system and  the traffic environment. Im-
provement  of the traffic environment and efforts  to find  alter-
native  control  methods  are  discussed. Alternatives involve
such practical  steps as restrictions on traffic,  improvement of
automobile  structure and functions, and city planning. Another
approach has not yet been adopted by any other country.  Con-
ventional tests on auto exhaust gas  are directed  toward  mea-
suring  gas  emissions from prototype  engines. It is obvious,
however, that  the problem of exhaust gas becomes more seri-
ous as  the  number of automobiles increases.  Therefore,  revi-
sion of  the present auto inspection  standard  is underway.
Owners  of automobiles are required to  have their cars  in-
spected periodically at six month intervals. With  the new  in-
spection  standard,  30% decrease in total CO gas emission is
expected in comparison with that obtained by the regular  test.

                         Cyclones are used for separating solid particles from gases,
                         although smaller and less expensive facilities would to the
                         same  job. The annular slot  separator is  illustrated and its
                         operating principle is described. Water canal experiments  were
                         performed for the design of the annular slot separator; stream
                         lines and  particle paths are  illustrated. Experiments  with  a
                         small  model separator (.diameter 125 mm) at which the slot
                         width of the conical rings  could be changed, were performed
                         and results as function of the collection efficiencies for certain
                         particle  sizes are tabulated.  With  an annular slot  separator
                         made  of spring wire, which has a mean slot width of 1 mm,  a
                         total collection efficiency of 95% was obtained with  the  same
                         dust. Very narrow slots around or below 1 mm are permissible
                         only with dusts which have no tendency to adhere. The deflec-
                         tion separator is illustrated. The air is deflected at the end of
                         the tube  conveyor by 180 deg with the aid of secondary air.
                         By the centrifugal movement  of about 30,000 ml sec  imparted
                         on the air, all particles are thrown out,  despite the very  short
                         residence time (only several ms). Particle size collection effi-

                         The  total collection efficiencies were  determined  with the
                         same dust but at various pressure losses, for the four cyclones
                         Van Tongeren, Korsa, the cyclone with counter-current flow
                         and vanes, and the cyclone  with the helical plate  covering.
                         Measurements were  performed under the following conditions:
                         the specific throughputs were constant, the maximum diame-
                         ters of the whirling chambers were the same  as the conical
                         parts of the  chambers, the total lengths of the cyclones  were
                         equal,- and the settling chamber  and the cyclone outlet into
                         that chamber remained unchanged. Under those conditions,
                         the collection efficiency  was practically  the same for all
                         cyclones. A comparison of designs also showed that  the in-
                         vestment costs are  practically the  same.  The  existing minor
                         differences diminish still further when the costs for a series of
                         collectors are considered, since all structural features  including
                         the dust feeder, the  settling chamber, and the removal system
                         can be constructed  alike.  Only  the cyclone with the helical
                         plates will be less  expensive.  The  Van  Tongeren  cyclone
                         requires slightly more space. As far as  wear and tear is con-
                         cerned,  the small cyclones with tangential inlets are not par-
                         ticularly advantageous. The cyclone with vanes and counter-
                         current  flow  offers a  better  resistance in  this respect. The
                         economy  of  cyclone separators, particularly  with  in-series
                         designs, depends first and foremost on the specific throughput
                         and the selected pressure loss and hardly on the design of the
                         individual cyclone. (Author conclusions modified)

tapering conically toward the nozzle mouth. The translational
and rotational energy of the air was increased by the chamber
shape. Maximum energy for atomizing a droplet was obtained
by metering it through the  atomization zone entrance through
which air from  the turbulence chamber excaped. When the
separation of hydrophilic sodium sulfate and hydrophobic par-
ticles was tested in a spraying tower, fine particles were found
to follow the flow line around the water droplet and to remain
in the carrier gas. Only 10-50% separation efficiency was ob-
tained with hydrophilic dust particles below 0.5 micron. Values
for the separation of hydrophobic dusts were even lower. The
separation of 0.3-0.5 micron particles was improved up to 60%
by the condensation of vapors at the particles (nuclei conden-
sation). The separation of the hydrophobic dusts was improved
20%  by pretreatment with wetting agents.

contained in crude oil are mercaptans,  aliphatic sulfurs,  bisul-
fur compounds,  thiophene, and so  on. Hydrogen sulfide  is not
an important  component,  but  sulfur  compounds change  to
hydrogen  sulfide by decomposition  or hydrogenation  in the
course of purification. Hydrogen sulfide is removed by absorp-
tion    by    alkanolamines  such   as   monoethnolamine,
diethanolamine,  triethanolamine, methyl triethanolamine, and
diisopropanolamine. Hydrogen sulfide absorbed by an amine is
stripped by hot steam. Sulfur is obtained by partial combustion
of the hydrogen sulfide. One-third of the hydrogen  sulfide is
burned and converted to sulfur dioxide which reacts with the
remaining two-thirds to generate sulfur.

Four examples from the roasting process with chlorine demon-
strate how the treatment on nonferrous ores has been changed
to meet the demands of the metal industries.  The percolating
leach, the roasting process, the sulfur dioxide percolation, and
the reduction  of the Fe concentration in the waste water are
discussed.  The  concentrations of  elements remaining after
roasting  with chlorine  are listed  and  discussed. The new
method of volatilization with chlorine, applied to non-ferrous
residues poor in metal, is  described. In addition, the results
achieved  by an experimental  plant with a  capacity of 100
tons/day is discussed.  Numerous charts on  statistics, flow
charts of various systems, and illustrations are given.

A theoretical analysis of the dust catching efficiency of a sin-
gle  fiber was performed and good agreement with experimen-
tal  measurements  was  obtained.  Using the assumptions  that
the dust particle is spherical;  the  filter fiber, cylindrical; the
fiber surface, clean; that the particle adheres to the fiber sur-
face;  and that the electrostatic force is  negligible,  together
with gravity and chemical reaction, an approximate  solution of
Oseen's equation of fluid motion was calculated by a large-
scale  computer. Effects  of inertia and diffusion were taken
into consideration when calculating the efficiency. The experi-
ment  was performed on a packed layer of filters,  and the
result was modified for a single fiber. The quantitative agree-
ment  between  the theoretical  and experimental calculations
suggests that the dust collecting efficiency of the packed filter
in practical use can be  estimated with little error from the
theoretical calculation of the  diffusion and inertia. The ten-
dency of the experimental value to exceed the theoretical one
is attributed to the neglect of electrostatic effects and so forth.
A study of those effects is currently in progress.

The prospects for reducing  emissions  from internal  com-
bustion engines  or developing alternative  engine systems are
reviewed. Internal  combustion engines, which include  Otto,
Diesel, and Bray ton cycles, are divided into reciprocal and ro-
tary types. The  engines have 2 or 4 cycles or in the  case of
hybrid engine,  a mixed cycle.  Theoretically, the exhaust gas
composition can be less  than 25 ppm hydrocarbons, 0.25% car-
bon monoxide and 100 ppm nitric oxide. In practice, however,
the minimum reduction attainable is twice as much, with con-
trol devices costing from  $50 to $300.  Replacement of the
gasoline engine with other types of internal combustion engine
is not realistic, and improvements in the control of exhaust gas
are aimed at  the  present-day  gasoline engine. Gas  turbines
emit fewer pollutants than other prime movers, but their use,
especially for vehicles  less than 200 hp, is  rather  limited.
Steam engines and Stirling cycles are remote alternatives; they
will not replace gasoline engines in  the near future. For the
electric car,  an alternating-current motor is promising. Ad-
vantages and  disadvantages,  of lead-acid, Na-S, and  L1-C12
cells  are  discussed, together  with  a  fuel  cell of  H2-O2,
hydrocarbons, methanol, ammonia, or hydrazine. An  energy-
to-weight ratio of fuels is another important factor is consider-
ing future automobiles. Gasoline or kerosene have the  best
value. Hydrogen has a value of 1/2 the ratio of propane, even
when used as a magnesium hybrid.  In conclusion, improved
exhaust-gas cleaning techniques are  required for the internal
combustion engine.

REMOVAL  OF  SULFUR  DIOXIDE  FROM  FLUE  GAS

The problems of sulfur dioxide pollution were solved by direct
desulfurization of heavy  oil and exhaust gases, and diffusion
from tall chimneys. Absorption in an absorption column was
described. The  packed column and spray column which are
usually used have many faults. Spray nozzles become clogged
and  their cleaning  requires too  much  time.  The  apparatus
becomes large for treating large quantities of gas and requires
frequent maintenance. The inclination of flaw lowers the effi-
ciency.  A   turbulent  contact  absorber solves  the  above
problems. It has two grids at the upper and lower parts of the
absorption  column and light plastic  balls are packed among
them. Gas is blown from the lower nozzles and the absorbent
is  sprayed  from the upper nozzles. The plastic balls  move
violently by  the impaction force  of the gas  and liquid. The
plastic balls are- covered with new absorbent enabb'ng them to
absorb gas. The column does not become clogged because of
the cleansing effect of the moving balls.  The  absorbent is
usually an alkali solution or sea water. The desulfurization rate
of this method  is higher than  90% for 90,000  N cu m  of ex-
haust gas per hour.

Dust generated  in the manufacturing of cement is high in elec-
tric resistivity and  has an  erosive property.  A rotary  dryer
generates high amounts of dust whose apparent resistivity va-
ries considerably with the treatment of the raw material. A ro-
tary kiln generates dust the apparent resistivity of which is
high. By considering such variabilities,  an effective dust col-
lecting system can be designed. Dust generated by a packer is
a part of the final product and has to be precipitated and col-
lected  by a special dust collector. An electric precipitator is
usually  controlled  by reading  the voltage of the transformer
and the amperage of the discharge-amperemeter. For the most
effective operation  of the precipitator, a precipitative voltme-
ter has to be used. The spark-count controlling method can be
adopted for the dust of low resistivity. Plumes or smut result
when precipitating efficiency is not satisfactorily high. In the
carbonic industry, the production  of electrodes for metal refin-
ing and  other purposes  and the  production of carbon  black
have to be considered  first  with  respect   to air-pollution
prevention. Dust generated in  the manufacturing of  electrodes
is low in electric  resistivity,  has little cohesive power, and
contains some higher- boiling hydrocarbon; thus, a stabilizer is
necessary.  Dust generated  in  the manufacturing  of carbon
black  can   not  be  precipitated  by an  electric  precipitator
because of its special properties,  but it can be precipitated by
a special unit system of dust collectors. In other parts of the
ceramic industry, it is easy to precipitate dust by an electric
precipitator,  but most  of the  factories  are small in scale so
special methods of treatment are necessary.

                         The separation of  fluorine compounds  and dust from waste
                         gases  of aluminum plants was  studied in the laboratory. A
                         suitable scrubbing liquid was determined for the waste gas; the
                         developing compounds had to be soluble to avoid crystalliza-
                         tion in the dust collectors and on pipes. Four test series were
                         carried out with  a rotating wet collector. The fluorine com-
                         pounds could be removed to  a  large extent with an alkaline
                         scrubbing liquid. A  slight dependence of  the degree of efficien-
                         cy on the pH value of the scrubbing liquid was observed. At
                         pH 8 to 12, the gaseous fluorine compounds could be removed
                         to a residual concentration of less than 0.5 rag/standard cu m.
                         The salt content of  the circulating scrubbing liquid increased in
                         the course of the experiments to  a maximum of 64 g salt/liter
                         water. The fluoride content of the scrubbing water reached 7 g
                         F/l. Maintenance of a pH of more than 10.5 and a salt content
                         of less than 70 g/1 helped to prevent any incrustations.  This
                         necessitated periodic replenishment of the  spent  scrubbing
                         liquid  by fresh water. The spent liquid  was treated with alu-
                         minum salts to precipitate the fluoride in the form of kryolith.
                         The dry precipitant contained between  48 and 51% F which
                         could  be  reused.  The  sludge  collecting in  the  circulating
                         scrubbing liquid had a settling time of 2  hours. Flocculants did
                         not reduce  this settling time.  The water content of the  sludge
                         was 98%.

                         Because the desulfurization of heavy oil  is an important aspect
                         of air-pollution abatement, plants for the hydrodesulfurization
                         of  distillate oils (naphtha, kerosene, light oil) are  often  con-
                         sidered indispensible. In the United States, the hydro- decom-
                         position method is  finding rapid acceptance. The demand for
                         high-quality gasoline  promoted the  development of the high-
                         pressure, steel forming,  and  the  partial-oxidation method for
                         the production of high-purity hydrogen. These techniques are
                         applied in both indirect and  direct desulfurization processes,
                         many of which have been introduced in Japan. Flow charts are
                         presented  to  illustrate direct and indirect processes as used
                         alone  or in combination. Desulfurization by reduced pressure
                         distillation  is a  typical indirect desulfurization method.  A
                         straight asphalt is obtained at the bottom of the reduced pres-
                         sure flash  tower; its sulfur content is high. If this asphalt can
                         be sold at a profitable price, it will be a large gain to the desul-
                         furization of heavy oil in the oil factory.  Also included are a
                         direct  residual-oil  desulfurization  method  and  an indirect
                         method which uses desulfurization equipment on reduced pres-
                         sure  residual oil. It  is  concluded  that the general trend is
                         toward the direct desulfurization, although an optimum com-
                         bination of the direct and indirect methods  should be  con-
                         sidered.

A new method of cleaning air by adsorption with artificial rain
is presented. The basic idea is to remove ultra-fine particulates
of less than 0.3  micron from air by forming a mist. The par-
ticulate becomes the nucleus of a water droplet, seen in rain
or snow. Outside air is mixed with room air and led to the pri-
mary  air-cleaning chamber, where most of  the  pollutants are
removed by humidification. After heating, the air is humidified
in the secondary air-cleaning chamber which is equipped with
a heat exchanger. When  the  humid air near the  saturation
point  is  cooled, a temperature  decrease does not occur in
water vapor because of its  large latent heat. Solids  such as
dust, however, are quickly cooled because of their low latent
heat, and absorb the heat  of the supercooled vapor. Thus the
dust is covered with water, the water droplet grows in size as
cooled, and falls downward. The small size of the initially
formed water droplets, and the low temperature and humidity
of the ambient  atmosphere  are the main  features of  this
system, enabling the  removal of ultra-fine particulates  and
gaseous pollutants. This method  was contemplated  in 1967, a
patent application made in 1968, and brought into operation
for a large electronic factory in the summer of 1969.

The advantages of using oxygen  for steel production have led
to  the  development  of  a  number  of  new metallurgical
processes, one of the most  important being the oxygen con-
verter process wherein oxygen is blown on a metal bath that is
charged into the converter  from a blast furnace  or cupola.
Dust in converter gases is  generally known as 'brown smoke';
it consists mainly of vaporized iron oxides and manganese ox-
ides,  as well as vaporized slag components.  Measures to be
applied during  the  blowing  period  in the  converter  and
designed to reduce the emissions of brown smoke by modifica-
tion  of charge  compositions or converter  operation are un-
feasible with one exception. To keep  dust emissions within
desirable limits, converter  waste gases must be cleaned. Three
collectors discussed are filters, electrostatic precipitators,  and
wet scrubbers. The operating factors influencing the separation
efficiencies of these methods are noted. To be suitable for the
process, the collectors should have an efficiency of 98%. It is
further recommended that each converter be provided with its
own waste gas  stack from which gases are led by a cooling
unit  to the collector.  Oxygen-blown converter plants should
also be equipped with stack flares to insure the ignition of CO-
containing waste gases.

Studies  and experiments are  reported relative  to the general
properties of radioactive contaminants and the characteristics
of atmospheric  contamination.  The  control of  atmospheric
contamination was approached from the point  of view of lo-
calizing contamination and conducting it  through controlled
channels to a point where  it can either be collected or diluted
sufficiently prior to its releases to the atmosphere to eliminate
any  possibility of external contamination. The physical and
chemical contamination  of surfaces is also  discussed,  along
with measures for their prevention.

DUST REMOVAL FROM BITUMINOUS MACADAM  MIX

refs.
About 50 million tons  of bituminous macadam mix is produced
annually in West Germany, in 1800-2000 stationary and mobile
plants, releasing more than 1  million tons of dust which  need
to be processed by separators. The mineral constituents, grain
size 0-35 mm, are continually dried and heated in a stream of
flue gases from  a rotary  kiln.  The  finer particles  become
suspended  in this stream of gas and must be removed from it
so as to conform to legal  regulations.  A federal regulation of
September 1964 sets the  maximum acceptable emission level at
150-750 mg/cu Mm, varied according  to the quantity of flue
gas. The limit for dust of less than 10 microns is 150-300 mg.
A regulation of the  Province of  North Rhine-Westphalia  of
October 1967 sets limits according to 5 categories of gas dust
content. The  dust content of the flue  gas  depends on the
granulometric  fineness of the raw material and on the rate at
which the gas flows through the kiln. Measurements show that
unwashed  material produces  150 g/cu Nm,  a mixture  of
washed  and  unwashed  material  yields 70  g, and  washed
material,  40  g. Kilns  can be  protected  against improper
packing or overloading,  and the supply of  gas  fed to  the kiln
can  be  limited to the amount actually necessary for efficient
operation,  which will discourage  personnel from using  im-
proper procedures. Measurements made in 1968 at 13 plants
indicate  that the type of  mineral used has a negligible in-
fluence on the amount of dust produced. The present state of
technology has no solution for the problem of flue gases con-
taining more than 150 g/cu Nm, which necessitates controlling
production procedures in  such a  way as to  keep below this
limit. Scrubbers are  usually adequate for  purification of the
emissions, with bag filters or electrostatic filters for especially
large plants.

A review of three papers presented at the meeting of the Hard
Coal Mining  Association in Essen between Oct. 29 and 30,
1968 is given. The  first paper  dealt  with  mining  and coke
production; the second, with methods for reducing the sulfur
content in coal; and  the third, with specific details of coking
plants  (type of  coke ovens, etc.). In the past few  years, the
average sulfur content in the coal mined in the Ruhr Valley
amounted to  1.12%.  The  fraction of organically bound sulfur
amounted to 40%, and 60%  of the total sulfur content is bound
to iron. There are wet and dry coal desulfurization methods.
Of  the various wet  methods,  floatation was  best  suited for
removal of the  pyrite grains with less than 0.5 mm diameter.
The wet-operating vibrating screen was  best suited for pyrite
between  0.06 and 3 mm  and the settling  tank for material
above  1 mm. The dry methods are not as efficient  as the  wet
methods, but they are used in West Germany  because 40% of
the hard  coal ready for use is dry. With  a magnetic separator
with a field strength  of 18,000 gauss, the sulfur content in the
grain size class of 1  to 0.1  mm could  be reduced from 2.8 to
1.6%. This was accompanied by  a carbon loss of 14.9%. With
laundering, the sulfur content could be  reduced, in favorable
cases,  to 33.7% and in unfavorable cases to  76.2% of the intial
content.

Sulfur occurs in coal in organically and inorganically bound
forms. The inorganically bound  sulfur appears as  pyrite  and
markasite. About 65% of the coal-sulfur is  organically bound.
There  are several possibilities for lowering  the sulfur content
in coke,  including electrostatic and magnetic separation; treat-
ment with gaseous, fluid, and molten reagents; decomposition
by  bacteria;  introduction of solids or  reducing or oxidizing
gases during  the coking process;  and thermal decomposition of
the coke. Another solution  is the removal of the coal-sulfur by
reduction or hydration with hydrogen during pyrolysis.  By
providing an excess  of H2  at the moment of decomposition or
rearrangement  of the sulfur  compounds,  the formation of
hydrogen  sulfide and  its  simultaneous removal  with   the
volatile components is assisted. This  method is  particularly
well suited for the coking of fine coal in a  rotating bed. Each
grain of coal or coke is surrounded by the reaction gas, the ef-
fective surface presented to the gas is much higher. The possi-
bility  of H2S recombining with  the solid particles to organi-
                        cally or inorganically bonded sulfur is limited by the rising ef-
                        fect of the carrier  gas. Sulfur removal is better  with  an in-
                        creasing length of stay and gas speed and with a reducing coke
                        grain size. A temperature of about 800 C is optimal.

                        In  a comparative study of  the absorptive efficiences of  four
                        kinds of activated charcoal (AC-Q, AC-G1, AC-Sh, and  AC-C)
                        for  sulfur  dioxide, the  saturation  value  of absorption  was
                        determined by thermal balance measurements. In addition, the

                        tent on absorption were evaluated. The results show that AC-
                        Q is superior to the other  activated charcoals and  that the
                        removal rate of SO2  is a function of time of absorption and
                        volume of treated gas.

                        As part of  a study of the refining of sulfur from pyrite ores by
                        fluidization, reduction of sulfur dioxide  gas  by coke  in a
                        fluidized bed  was investigated. The effects of reaction  tem-
                        perature, gas composition,  gas flow rate, and the volume  of
                        coke on the reduction reaction were examined. Above 1000 C,
                        a 100% reduction of sulfur dioxide  was obtained by prolonging
                        the  period of gas-coke contact. However, hydrogen sulfide,
                        carbonyl sulfide, and carbon  disulfide  were formed  as  the
                        result  of simultaneous  side reactions.  These side  reactions
                        were minimized by reducing the reaction temperature and ex-
                        tending the contact time still further, but sulfur  yields were
                        not satisfactory. Complete conversion of sulfur dioxide  to sul-
                        fur appears to require its  reaction with hydrogen sulfide  or
                        carbonyl sulfide. Experiments were also performed in a fixed
                        bed. The fixed bed data and the fluidized bed data were com-
                        pared  and  mathematically analyzed to determine the quantity
                        of  sulfur  dioxide  reduced by the coke and the  quantity
                        reduced by the carbon  monoxide formed  from  the  carbon
                        dioxide generated  by the coke. The  effect of flow conditions
                        on reduction rate coefficients is discussed.

                         In  a Japanese process for desulfurizing flue gas, sulfur dioxide
                         is adsorbed by activated carbon which is regenerated by wash-
                         ing and drying. A  standard operating cycle including adsorp-
                         tion, washing, and drying is 60 hrs. A 90% desulfurization rate
                         was obtained when the process was operated for about  2300

hrs (60 cycles) in a test plant. No weakening in the adsorptive
capacity of the carbon was observed and dilute concentrations
of 20% sulfuric acid were obtained continually from the wash-
ing water. The method is  to be tested  again in  a large-scale
pilot plant. Advantages claimed include  excellent flue-gas dif-
fusion, since the exothermic adsorption reaction maintains
stack temperatures in excess of 100 C, reclamation of sulfuric
acid and sulfates from the wash water, conservation by re-use
of washwater, and  adaptability to existing boiler structures
without boiler modification. Several other dry methods of
desulfurization are also described.

A method for removing sulfur dioxide from power plant emis-
sions by activated manganese oxide is described. The method
involves adding powdered activated manganese  oxide  to the
exhaust gas flow, then oxidizing the gas in a slurry containing
ammonia.  The manganese oxide can be regenerated, and am-
monium sulfate is recovered as a by-product. The advantages
of this system include a high SO2 absorption rate; recycling of
the manganese oxide; low pressure drop; desirable operating
characteristics, and recovery of ammonium sulfate.

The  results  of a series of tests to determine the ability of
limestone  powder to remove sulfur dioxide from power plant
effluent are discussed. Various conditions, such as making the
injection particles as small as possible, using limestone with
1% or more iron content, scattering the powder evenly in the
boiler, and placing injection points on the chimney where the
temperature is between 1000-1200 C, greatly enhanced the rate
of removal. With a ratio of limestone to crude oil of 15% by
weight, the removal efficiency is 50-60%. Dust accumulation
on the interior walls of the boiler, and especially on the reheat
tube, is great.  Further work  is  required to eliminate  this
problem. (Author abstract modified)

LOW SULFUR CRUDE OIL. (Teiio genyu). Text in Japanese.
Nenryo Kyokaishi (J. Fuel Soc. Japan, Tokyo), 49(515): 116-
122, March 1970.
To meet new restrictions on the allowable sulfur content of
fuel, Japanese oil companies are increasing their imports of
low-sulfur crude  and heavy oil and installing more plants for
the hydrodesulfurization of heavy oil. According to govern-
ment projections, the hydrosesulfurization facilities will be
required to have a  capacity of 650,000 BSD by  1973. The
present capacity  is 65,000  BSD. The current capacity  of in-
direct desulfurization plants is 220,000 BSD. The ratio of low-
sulfur crude oils to  the total volume of crude oils must in-
crease from 12% in  1968 to about 20%  by 1973. Low-sulfur
crude oils, which account for more than 40% of worldwide
crude oil output,  are  effectively and cheaply  desulfurized.
Judging from their present distribution status, however, it ap-
pears unlikely that Japan can substantially increase its imports.
It will instead have  to rely on the costly desulfurization of
heavy oil.

A process  is described for  the economic  removal of  pyrite
from the finest fractions of coal or pyrite-enriched coal dust.
It is based on the disintegration  of coal into a light and essen-
tially pyrite-free component and a heavy  pyrite-enriched com-
ponent, followed by the dry separation of the latter component
according to its density. In the separation process, thin  layers
of coal  dust are uniformly distributed across the entire width
of a vibrator-sluice and guided over it. The sluice comprises a
series of vibrating troughs  which become  successively  more
narrow  and deep. In the course of its path overthe troughs,
the coal-pyrite mixture spreads  out into particles having the
same size but varying in weight according to  their densities.
The  pyrite components  are collected in end plates attached to
the troughs; coal dust is passing over the  plates. The collected
pyrite is removed by an optically controlled throughput device
which operates discontinuously, while the desulfurized coal
components are  again combined with the  light components.
The collected dust is used for coal-dust firing. The process has
applications  both for the treatment of coking  dust  and the
desulfurization of fuel dust for coal firing.

AIR POLLUTION TRANSLATIONS
In response to requirements limiting the sulfur content of fuel
to 1.7 wt percent, Japanese refineries built topped crude desul-
furizers or vacuum gas oil desulfurizers. The refineries are
now  endeavoring to determine the optimum operating  condi-
tions of these desulfurizers to satisfy the more severe sulfur-
level requirement which is expected to be set at less than 1.5
percent in the near future. It is noted that no type of desul-
furizer can be economically operated at the current price level
of fuel oil. Moreover, reducing the sulfur level of fuel oil to
less than 1 wt percent will not solve the  air pollution problem
in densely populated  areas  where the  number of factories
burning oil is expected to double. New processes for produc-
ing more gaseous fuel must be explored.

Data from pilot testing of a packed absorber designed for ex-
tracting sulfur dioxide  from low-concentration gases using lime
suspensions are  correlated. With an irrigation solution  of pH
greater  than 6,  the resistance of the liquid phase becomes
negligible  while the total coefficient of mass transfer may be
equated to the partial  coefficient in  the gaseous phase. The
coefficients of mass transfer vary proportionally to the first-
order change in linear gas flow  rate. The dependence  of the
mass-transfer coefficient  on pH of  the  irrigation  suspension
over the range  5.3-6.3 and on solid  particle content over the
range 20-32 wt % is plotted.

The technique and results of an experimental coal gasification
process are evaluated. Several modified  equations  are recom-
mended for computing back reactions:  these suggest  that a
limitation  to a differential reactor or to a solid bed, in which
the concentration of the reacting gas remains constant over the
entire bed length, is useful. In interpreting measured results of
the gasification process, the following reactions are considered
significant: FeS2 + H2 in equilibrium with Fe + H2S at 600-
800 deg and the reaction of heterocyclically bound organic sul-
fur at 600 deg  and higher.  Further  analysis is suggested to
determine whether the chemical  reaction or the diffusion de-
cides the speed of  the above reactions. It is also proposed that
CaO dolomitic lime and manganese oxide be considered as ac-
ceptors for the process, with reference made to U. S. patents
covering these acceptors.

                        With wet cleaning, the dust-laden gas is mixed with water by
                        some method. In many cases, the water is atomized and in-
                        jected into  a gas flow. These processes are of a hydrodynamic
                        nature, and can be theoretically examined. For a fundamental
                        analysis  of the processes, an analytical approach is needed.
                        The cleaning  capacity  (in the  form  of  the  dimensionless
                        parameter as a function of the droplet size, at a gas velocity of
                        20  ml sec, and for various particle sizes of  the dust carried
                        along) is graphically shown.  The data indicate  that there  are
                        certain droplet sizes with which an optimum cleaning capacity
                        can be achieved. With very large and very small droplets,  the
                        cleaning  capacity becomes zero. The  optimum droplet size
                        shifts to  increasingly larger diameters with increasing particle
                        size of the dust. The influence  of the gas velocity and  the
                        droplet size on the cleaning capacity for a certain size of dust
                        particles  is  illustrated.  The collection efficiency increases con-
                        siderably with increasing gas velocity for both large and small
                        droplets.  The  improvement  in percent  cleaning  capacity
                        achieved through increasing  the  gas velocity is much higher
                        for fine  dusts than for  coarse dust  particles. Some  practical
                        conclusions for the construction of wet cleaning  systems  are
                        given.

                        Analysis  of the emission sources for sulfur dioxide has shown
                        that emissions will continue to  increase over West Germany
                        and in particular the Ruhr Valley until  the year 2000. SO2 is
                        estimated to increase from about 3.65 million tons in 1969 to
                        4.5 million  tons  in 1980. Traffic and sulfuric acid plants will
                        decrease their emissions, as well as domestic heaters,  but
                        power iron  ore  sintering plants will be major S02  emission
                        sources.  To control these  emissions, the sulfur  content in
                        heavy fuel oil and to  a lesser extent in hard coal  must be
                        reduced.  In industrial centers only  low-sulfur or sulfur-free
                        fuels should be  used. In hard coal-fired and sintering plants
                        the  wasted  gases ought to be  desulfurized. Selection of an
                        adequate process should not  only reduce the SO2 emissions
                        but also  fluoride compounds, the oxides of nitrogen and poly-
                        cyclic aromatics.

a flowmeter.  The collection efficiency  as a function of the
flow velocity  for  a  three-stage electrostatic precipitator  is
shown. Velocity profiles in the precipitator model with gas dis-
tribution vanes and without installed gas distribution plates are
illustrated.  Computation of the collection efficiency loss  at
varying gas velocities in  the invididual precipitator  stages  is
tabulated.  For » filter  with straight gas feed, the separation
loss is represented as a function of the number of gas distribu-

The  operational  conditions of bag filters  used  for  emission
control in the  metalworking industry are illustrated by exam-
ples. In the zinc refining industry, bag filters are used at vari-
ous points. The baghouse for the independent electric power
plant which is provided to allow the exhausted material to cool
down is one example. Another is the baghouse for controlling
emissions from a smelting furnace exhaust. The applications  of
bag  filters to the aluminum  industry  is illustrated by the
baghouse used to control emissions from an alumina  coveying
process. In a powdered lead manufacturing plant, a  complete
dust collector  has  to be  provided  since the lead  dust  is ex-
tremely  toxic  and  cannot be allowed to escape into the at-
mosphere. Complete hooding is also necessary. In the nonfer-
rous metal working industry, emissions are commonly  worth
recovering. High efficient dust  collectors are adequate for this
purpose. In the iron and  steel industry, the collected material
from the exhaust is generally of little value, but dust collectors
are necessary for air pollution control. Their use  is typified by
baghouses equipped for controlling  emissions from electric-arc
steelmaking furnaces and  from  electric furnaces for ferro-alloy
manufacture.  In the metal processing industry, bag filters are
also used for controlling emissions from various processes. An
example is the baghouse  equipped for controlling emissions
from the finishing process of iron casting.

Tests were conducted to develop a means of counteracting the
accumulation  of NH4HS04, a combustion by-product with  a
low melting point, in the air-heater  of oil-fired  boilers. The
compoun is formed when ammonia  gas  is injected into the
combustion gas to neutralize sulfuric acid produced by the
combustion of sulfur-  bearing fuels. The  ammonia  injection
temperature zone is an important factor in this method. Ac-
cordingly, ammonia injection was applied to a boiler in a ther-
mal power plant for one month, using an injection rate  of
0.6/0.07  wt %  of fuel oil fired, and an injection temperature
zone of -180 C in the flue  gas. A satisfactory reduction of
NH4HSO4 accumulation  was obtained under these operating
conditions. Experiments were also conducted on the effective-
ness of  dolomite  powder injection in  reducing corrosion
caused by sulfuric acid in the combustion gas;  using an air-
cooled corrosion probe, reduction of corrosion was observed
to begin at an injection level of 0.3 wt % of fuel ooil fired. In-
jection of fly ash  also showed some potential as a  low-cost
method of reducing corrosion. (Author summary modified)

DESCRIBING  AMMONIA SCRUBBING PILOT PLANT.
Translated  from Japanese. Belov and Associates,  Denver,
Colo., 4p., April 22, 1970.
A pilot installation is described which simultaneously controls
a very high percentage of emissions of dust particles and 90 to
95% of sulfurous  acid gas. The apparatus  embodies a wet-
type, atmospheric  vapor exchange method, in which liquid is
poured through an  anti-corrosive synthetic net and spreads out
to form a film, through which the gases  pass with a special
contact mechanism. With  very little pressure loss, nearly in-
soluble gases are effectively absorbed.  Gas  that has been in-
ducted into the tower cannot leave without contacting the
treated solution, and since it makes contact repeatedly, the gas
absorption  rate is  greatly  improved. Because pressure losses
are small, the cost of running the gas conduction blower is
reduced. Flexibility, ease  of  operation, and  maintenance are
improved, and recovery of valuable particulates from the ga:
stream is facilitated. Applications include use in boilers, higl
temperature furnaces, control of sulfurous gas from  oil-burn
ing fuel systems,  odor counteraction, and gas recovery an<
heat exchange in the chemical and oil industries.

Fuel oil consumption  in the Federal Republic of Germany in-
creased from 17.9  million  tons in 1965 to 21.4 million tons in
1968, with the power plants alone accounting for about 25% of
this amount. A heavy fuel oil-fired boiler emits  between 0.23
to 8 kg dust/ton of oil. During normal operation  the dust con-
tains 90 to 95% of combustible matter, during soot blowing 75
to 93%. Dust concentrations  between 15  and 400 mg/cu Nm
could be measured in the  waste gas during normal operation,
and between 1000  and 10,000 mg/cu Nm during  soot blowing.
The gas contained 12% by weight sulfuric acid. Of the dust
particles, 80% had diameters of less than  20 microns, with 20
to 30% having diameters less than 5 microns. Dust  emission
measurements taken at four oil-fired boilers (16 to 20 tons/h)
revealed that  centrifugal  separators reduced the emissions
from between 46 to 55 mg/cu  Nm to between 24  and 40 mg/cu
Nm during normal operation, and from 1050 to 1870 mg/cu
Nm to between 104 and  174  mg/cu  Nm during soot blowing.
Better results can be achieved with electrostatic precipitators.
but they are considerably more expensive.

boiler plants precipitate rather uniformly with respect to quan-
tity temperature, and composition. On the other hand, sinter
waste gases contain additional metal oxide smoke which can
complicate the process of sulfur removal. Thus,  the process
selected  should have  no sensitivity to  disturbing  gas  com-
ponents and should have versatility with respect to the absorp-
tion of any of the sulfur compounds coming under considera-
tion. A desulfurization process was developed which is an ab-
sorption process with thermal regeneration of the charge ab-
sorbent. The process principle selected is based on the  reac-
tion of oxide compounds between a basic and an amphoteric
heavy metal component. The presence  of a compound Mg6M-
nO8 has been proven using X-ray structure investigation; the
presence of a compound MgSMnOS is also probable. In this
combustion, the basic component is used as the actual absor-
bent and  the heavy metal component as the oxygen donor.
This has  the effect of increasing the total activity of the  mix-
ture. For the same reason, the absorption of hydrogen sulfide
from waste gas is also made possible. In the thermal regenera-
tion of the charge mass, both components protect each  other
reciprocally against daactivation. Economic aspects were a pri-
mary consideration in the selection of the desired  components
for the absorption mass. This eliminated elements like Cr, V,
Mo,  and Zn. Though Ca and Mg were practical, Fe and Mn
were selected because of the rapid formation and stability of
the oxide compounds between them as well  as the inactivity
during absorption. All chemical and process-technological pre-
dictions made on the basis  of laboratory experiments  were
confirm. For oil-fired steam boiler plants, flue gas desulfuriza-
tion plants ready for practical use can be set up and operated.
Capital outlays and operational costs are given for an oil-fired
300 MW power plant, in addition to total annual operational
costs. A particular advantage of this process is that the charge
mass can be regenerated by various desulfurization systems at
a central location.

The main cause of obnoxious odor from kraft pulping (KP) is
in the sulfur compounds that arise in the process. Sulfur com-
pounds in reduced form are  odoriferous whereas  those in ox-
idized form are either  odorless or  just irritants. Tables are
presented on the amount of dimethyl  sulfide (DMS) that can
be retrieved from KP black liquor at various temperatures and
with different amounts of Na2S added. Different quantities of
organosulfur compounds released in KP of different types of
trees are  listed for various pulping conditions. In general, the
broad-leaved trees yield more odorant substances than do the
coniferous trees. The data were obtained by a process similar
to the theoretical method, and the quantity of organosulfur
compounds from real KP process is probably much smaller.
The gaseous sulfur loss balance sheet  for two factories in the
South (U. S.) show that most of the sulfur released is in the
H2S  emitted from the recovery furnace,  followed by sulfur
dioxide gas and DMS.  A brief description of a process for
deodorizing DMS by ozone  oxidation  is given. However, un-
less inexpensive methods are  found  for the  production of
ozone, the method is still far from application.

                        As  determined  by laboratory  experiments,  sulfur  dioxide
                        evolved in a small combustion furnace is removed at an equal

                        The reactivity of SO2 with limestone is improved by adding
                        ochre to the powder or using a lime containing more than one
                        percent iron. In the case of calcium hydroxide, a higher SO2
                        removal rate is obtained by injecting the  compound in slurry
                        rather than powdered form.

result of many years of selection and utilization of drought- re-
sistant woody and herbaceous plants, the city of Baku in the
USSR has been transformed into one of the most verdant ci-
ties. Air pollution by noxious gases,  smoke, and dust must be
combated. In the spring and summer, the leaves and  shoots of
plants turn gray because of dust and soot. Ash particles accu-
mulate in leaf stomata, interfering with the normal plant trans-
piration. The air under the trees is dusty and breathing is dif-
ficult. In these conditions, the usefulness of green plantings to
man is greatly reduced. The flowers of shrubs and herbaceous
plants must be  washed off by  sprinkling. This removes the
soot and dust,  moistens the air and soil, thereby  providing
favorable conditions for normal plant development,  while en-
riching the air with  water vapor and oxygen.  Suggestions are
given  for  improving the  green plantings  of hospitals  and
sanatariums in the Baku area.

A prototype electrostatic  precipitator for thermal power-sta-
tion smoke has two electric fields in a series, each constituting
an electro-filter with collecting and emitting  electrodes.  The
collecting electrodes are plates connected to the positive pole;
the emitting electrodes are wires connected  to the  negative
pole. The d-c potential difference between the plates and wires
ionizes the air around the  wires by corona effect. During their
passage between the electrodes, dust particles  are electrically
charged by  the  ions or by molecular diffusion according to
their size. The charged particles are attracted by the oppositely
charged collecting surfaces on  which they come to  rest. The
electrodes are hammered or vibrated to free them of deposited
dust, which falls by gravity into receiving hoppers.  The effi-
ciency of the filter,  defined as  the ratio of the weight of cap-
tured dust to the weight of dust entering the device, depends
on  the  electrode  hammering  and  on  the erosion  of the
deposited dust layer. To determine  efficiency, soot deposits
are weighed and, to  find the mass of unretained soot, the con-
centration is measured at a point upstream of the electro-filter.
Preliminary  tests of  the filters are in progress at a special ex-
perimental center.

The needles of pine trees and  the leaves of birch and aspen
trees were studied to determine their effectiveness as dust fil-
ters. Leaves of identical appearance retain dust differently de-
pending  on  their  specific  location.  Leaves  from inside  the
crown were covered with more dust than the leaves from the
periphery of the crown. The ability of pine needles  to act as
dust filters is also  a function of their age. Three-year old nee-
dles located inside the crown detain  more dust than needles
from the outside after one year.  The morphological structure
of the leaves  also influences their dust-retaining ability. The
pores of pine needles form depressions resulting in an uneven
surface  which retains dust. Birch and aspen  leaves,  however,
are sufficiently mobile  so  that  the wind  can  remove  the
deposited dust. Plantings growing in the vicinity of the city of
Leningrad retain 80.1% of the precipitation/surface of ground
dust. From this quantity, up to 40.2% can be attributed to pine
needles. The investigations thus showed that the pine is a good
retainer of dust, and should be  included in the  plantings  of
parks and wooded areas near an industrial center.

The Porcheville Power Station consists of four  125 MW units,
each equipped with a combined  mechanical  and  electrostatic
dust-removing device. These units were placed  in  operation
between March 1956 and April  1957. The original dust-remov-
ing devices proved to be  insufficient, the efficiencies falling to
less than 70% under maximum load conditions.  A  series  of
modifications  were  undertaken to improve the efficiency  of
the devices. These included increasing the time during which
the gases remain in the electrostatic precipitator, changing the
location of the mechanical collector, cleaning  and adjusting the
electrodes, improving the soot flow  and air-tightness of the
chambers, and modifying the electric supply. These changes
resulted in a 20 point increase  in efficiency; this corresponds
to an approximate 5 to 1 reduction in the amount of dust
discharged into the  atmosphere.  The present objective is  to
maintain the dust-removing devices in good operating condi-
tion by keeping the electrodes clean, accomplishing an op-
timum adjustment  of the rectifier voltage, limiting the number
of emitting  electrode breakages,  and obtaining a perfect ad-
justment  of all mechanical parts of the  devices.  After the
completion of the work  in  progress,  efficiencies of  96% for
maximum boiler load and 98% for normal production condi-
tions will be possible. Of particular interest was  the benefit ob-
tained by relocating the  multicyclones downstream  from the
electrostatic precipitators. Prior to the relocation the  precipita-
tors received only  small particles  which formed a tightly cling-
ing coating on the  electrodes which resisted cleaning agitation.
When  the  relocation  of  the  multicyclones  permitted  the
precipitator  to receive larger particles, these interrupted the
surface of the coating on the electrodes sufficiently to greatly
improve cleaning efficiencies.

Fluid-bed  combustion generally describes the oxidation reac-
tion that takes place in the fluid layer. The fuels used can be
solid, liquid, gaseous, or any combination of these. Some basic
observations concerning  fluid-bed technology are made. The
basic types of fluid-beds are described. The theory of opera-
tion  of the fluid-bed involves turbulent fluid flow and mass
exchange. Mathematical  relationships of fluid-bed phenomenon
are determined. Fluid-bed combustion has the potential ability
to effectively bind oxides of sulfur to alkaline additives by a
drying method. It can also utilize a greater size range of coal
fuel, and it reduces the ash content in the effluent. Designs of
various fluid-bed reactors are given. Research into the com-
bustion properties of various fuels is discussed.

odor  problem at the the same time. Raw animal fat of high
quality and with 75% oil content is attractive from the stand-
point of oil and fat processing. Other animal rubbish and fibers
consist of as much as 50% water and gelatine and are rather
hard  to be  utilized  for  oil and fat processing and also for
livestock feed. The main efforts were directed to eliminate the
drawbacks of the  conventiona type of open  kilns. The local
overheating of the  kiln  due to the oilburner it uses scorches
the materials and results in poor-qualit oil and fat  byproducts.
The merit of the currently devised plant can be characterized
as its closed system. The kiln designed to collect odor bearing
vapor and to send it to a pressure reducer where the emission
gas is mixed with water for dilution effect. Th material can be
treated to a better quality under reduced pressure along with
less temperature variation according to the kind of raw materi-
als being processed. Odor contained in  the vapor can  be
reduced. The flowchart of this closed system plant and related
data are presented.

                        At a coke dry-cooling plant  in  the Soviet Union, dust is
                        removed from circulating gas to a dust-settling hopper before
                        the  gas  stream  enters  the  waste heat boiler and again in
                        cyclones before  it enters the exhaust fan. By fitting the hopper
                        with high-strength chamotte baffles, the average  dust content
                        of the gas entering the cyclones  was reduced to 3-4 g/cu m
                        compared to 4-6 g/cu m when the baffles  were supported by
                        welded steel girders faced with guniting material. Erosion of
                        the  cyclones was  checked by lining internal surfaces  of all
                        conical sections with cast stone  slabs.  Coke breeze and dust
                        from the hoppers and cyclones is discharged through a sludge
                        pipeline to a settling tank on a quenching  tower. Blockage of
                        the pipe was reduced by increasing its angle of inclination and
                        the addition of more wash down nozzles along its  length.

                        There is  wide interest in utilizing ammonium sulfite-bisulfite
                        solutions  to produce ammonium sulfate  fertilizer since the
                        solution  can be converted to sulfate without expenditure of
                        sulfuric acid. Furthermore, sulfur-containing waste' gases  pro-
                        vide an unlimited source of ammonium  sulfite-bisulfite. In the
                        'catasulf  process,' hydrogen sulfide from coke  oven gas is
                        catalytically oxidized to sulfur dioxide, which is then absorbed
                        •together with ammonia to form the sulfite-bisulfite  mixture.
                        The latter is processed in an autoclave  at high temperature to
                        ammonium sulfate and elementary sulfur. Disadvantages of the
                        process are that the decomposition of the sulfite-bisulfite mix-
                        ture in the autoclave has to be performed at high  pressure and
                        that the autoclave must be made of heat resistant  materials. As

determined by a kinetic study of the process, decomposition
of  the  ammonium sulfite-bisulfite  solutions  to ammonium
sulfate and elemental sulfur can be performed within a techni-
cally acceptable time (1.5 hr) in an open apparatus under nor-
mal  pressure.  For  this  purpose,  the  solution  must  be
vigorously mixed in the first stage of the process with a large
excess of sulfur, and at the same time heated to 100-105 deg to
accelerate   the   formation   of  intermediate   ammonium
thiosulfate.  After  the  required  thiosulfate  concentration  is
reached, the solution must be acidified (with H2S04 or SO2) to
convert  the residual sulfite to  bisulfite and  to accomplish
complete decomposition of the solution. Pilot-plant tests of the
technique  could result  in  the  early application of more effi-
cient methods of purifying sulfur-containing gases,  including
techniques  for the simultaneous utilization of  NH3  and H2S
from coke oven gas.

36, April 1970. CFSTI: PB 190788
A discussion of air pollution in the Soviet Union is presented.
Automobile  emissions are not  as serious a problem  in  Russia
as they  are in the United States, particularly California. Stack
gases are being filtered  to remove the particulates. Sulfur diox-
ide can be removed by desulfurization of fuel, by utilizing high
chimneys, by replacing sulfur-containing fuel with natural gas,
and by reacting the sulfur with other chemicals  to capture it.
Two methods of capturing the sulfur are the cyclical  magnesite
and the  ammonium autoclave methods. A description of these
methods is given, including  their  shortcomings.  Filtering
petroleum at the refinery  and treating the resulting hydrogen
sulfide by the Klaus method  would be an expedient  way to
handle the problem. Catalytic oxidation  methods for treating
hydrogen  sulfide  are described.  Hydrocarbons  are  generally
controlled  by  either absorption  or adsorption. Filtering of
waste gases and ventilation  of large quantities of air  are  ex-
pensive  processes. If they can be avoided by improving other
operations, considerable economic savings will be realized.

PACKED COAL BED AS A DUST COLLECTOR (II).  Taiki
Osen Kenkyu  (J. Japan Soc. Air Pollution), 2(1):98-1001 1967.
Translated from Japanese. 8p.
Dust collection using packed coal was studied for treatment of
the exhaust of coal-fired  furnaces and incinerators. The coal
from which smoke was collected was fed into a combustion
chamber,  so that  no  dust trapping  device  was needed and
operation  could be  achieved  with  only a single  collector.
Generally, in the case of filtration, collection efficiency is un-
proved due to the deposition of smoke on the filter.  However,
the flow rate  of  gases is reduced due to thickening  of the
smoke layer, provided that the power of the suction  or blower
is maintained constant.  Consequently, it is uncertain whether
the rise of collection efficiency  was due to formation  of the
dust layer or to the reduction of flow rate. In this experiment,
the equipment was improved  so that both  effects  could be
separately evaluated. An  experimental  equation  of pressure
loss and collection  efficiency was derived for a nearly uniform
size of coal layer which was produced by sieving. An experi-
ment was also conducted  on packed beds of spherical active
carbon and glass spheres  in order to elucidate the feature of
the coal bed in comparison with the above two standard beds.
In this type of collector, the amount of coal employed for dust
collection  and  that  consumed  for  the  combustion  was
balanced;  this  requirement  imposed  restrictions  on  the
thickness of  packed bed, flow rate of  exhaust gas, area of
beds, and interval for replacement  of coal. For a  given coal
consumption, the gas flow rate was roughly determined, and
the area  of  the bed was derived from  the  optimum  face
velocity. Beds of 7 and 14 cm thickness were tested. On deter-
mining the optimum thickness of the beds, the interval of time
for the replacement of coal was derived. This procedure pro-
vided the  standard for practical  design of a  coal bed. The
smoke-laden gas of fixed volume  was drawn through circular
filters  up- and downstream of the  smoke  collector,  and the
amount of smoke was  determined  by measurement of light
reflectivity of  the  filter  surface  on which the smoke was
deposited.

REMOVAL OF SO2 BY FILTER IMPREGNATED WITH AL-
KALI.   Taiki  Osen Kenkyu  (J.  Japan Soc. Air  Pollution),
2(1):98-100, 1967. Translated from Japanese. 8p.
The superiority of filters impregnated with  chemicals for col-
lecting and analyzing atmospheric trace gases  has  led to ex-
perimentation of the above principle in  the removal of gases.
The removal  of sulfur  dioxide from air  was tested using
Philedon and Bonden filters impregnated with alkali. PI5/500
Philedon and No. 291 Bonden filters were soaked in 20% aque-
ous solutions of alkalis such as NaOH, KOH, and Na2CO3,
with 10% of glycerine added, and dried at 80 C. The filter was
fitted to a wind tunnel and its collection efficiency was mea-
sured for an  SO2 concentration on  the order of 10 ppm. The
face velocity through the filter ranged  from 46 to  96 cm/sec;
pressure drop across the filter was  1 mm of H2O. Collection
efficiency by the Bonden filter was 60 - 70%. Efficiency  by
the Philedon filter was initially almost 100% but the efficiency
gradually dropped with prolonged operation of the  filter. The
rate of reduction of efficiency was largest  with the filter im-
pregnated  with Na2CO3. With the filters  impregnated  with
NaOH and KOH,  nearly equal reductions of efficiency were
observed. Although the experimental values were scattered for
individual filters, the collection efficiency was still 80% even
after 10  ml of SO2 was  collected  on  1 sq cm of the filter,
which corresponded to the collection of 0.1 ppm of  SO2 for
about 500 hours with a face velocity of 50 cm/sec. No varia-
tion of efficiency with humidity was observed  for  the experi-
mental range  of 60 to 82%.

ELECTRIC FILTRATION OF SO2. Taiki Osen Kenkyu  (J.
Japan Soc. Air Pollution), 2(1):98-100,  1967. Translated from
Japanese. 8p.
To develop equipment for the removal of sulfur dioxide in flue
gas, a wet-type electric precipitator was  constructed and a
basic study of electric filtration of SO2 was performed. Liquid
was dropped along the inside wall of a glass cylinder of 35 mm
inner diameter. The corona electrode was placed at the center
of the cylinder and voltage was applied between the corona
electrode and the  liquid surface.  A known concentration of
SO2 gas  was  introduced from the bottom of the cylinder,
passed through the corona discharge, and was taken out from
the top of the  cylinder.  Sampling of SO2 was in accordance
with Japan Industrial Standard JIS-KO103-1963; titration was
employed for the analysis of SO2. As SO2 is an electronega-

live gas on which electrons are easily attached, its collection
efficiency was increased at a corona starting voltage of 5 kV
and the efficiency was constant with  voltages larger than a
certain value. The collection efficiency was always higher with
a negative corona electrode voltage than with a positive one.
With positive voltage above a certain level, collection was not
achieved steadily. A flow rate of about  100 ml/min. was most
adequate. Gas collection efficiency was greater than 95% with
an applied voltage  of  9  kV  and SO2  concentration  below
0.45%. In the preceding results, water  was employed  as the
collection medium. Further experiments were conducted using
a 5% aqueous solution of Na2CO3 and a 10% aqueous solution
of sulfuric acid. The collection efficiency was reduced with
the increase of SO2 concentration; this tendency was more
pronounced with the sulfuric acid solution. With a voltage of 7
kV,  the  efficiency with  the Na2CO3  solution was  almost
100%, whereas with the sulfuric acid solution it was only 35%.

In a desulfurization  system designed to recover  ammonium
sulfate, the possibility of  dust  passing through the collector
system and poisoning the catalyst was investigated.  An amount
of dust equal to 3,  6, and 12%  of  the  total weight of the
catalyst (roughly the amount thought to  have collected in a
period of 3 to 12 months)  was sprinkled on the catalyst and
flue  gas was passed over the catalyst at a stack  velocity of

                        Measurements of the state of adsorption of  sulfur dioxide on
                        activated charcoal demonstrated the partial existence of physi-
                        cal adsorption when SO2 was adsorbed at 100 C  with water
                        and oxygen. Most of the adsorbed SO2 was extracted (above
                        180 C) as SO4(-2) with water, the remainder with H202. Since
                        the same results were obtained with charcoal samples that ad-
                        sorbed H2S04 directly, SO2 appears to exist as SO3 or H2S04
                        on the surface of charcoal. Sulfur dioxide with 02 and H20 had
                        a greater tendency to be  adsorbed as H2S04 than did SO2 with
                        02 alone or H20 alone, and  the  speed  of  the reaction  was
                        faster. The implication of this  finding for adsorption of SO2 in
                        exhaust gas is noted.

                        Economic and engineering problems to be resolved before ap-
                        plication of wet methods of removing SO2  from  waste gases
                        are reviewed. Selection  of a  removal process is shown to be
                        influenced by the limit of absorption, the velocity of the reac-
                        tion, and the price of the absorbent. For instance, it is difficult
                        to use  organic solvents or basic  aluminate sulfate on gases
                        containing  less than one percent SO2. The price of,the absor-
                        bent comes into question because of the large losses when the
                        SO2 content of a gas is low. Organic  solvents and ammonia,
                        for example, are easily lost because of their high vapor pres-
                        sures. Another factor to be considered is the demand for and
                        prices of compounds recovered from SO2 gases. Consumption
                        in 1963 of recovered ammonium sulfate, sulfur, sulfuric acid,
                        gypsum, sodium sulfate, and sodium sulfite are summarized in
                        tabular form, as are the amounts of SO2 emitted by  power
                        plants,  sulfuric  acid plants, and nonferrous metal refineries.

methods are an ammonium process applicable to high-tempera-
ture gases from  sulfuric  acid manufacture, a manganese ox-
yhydroxide  process  with  recovery  of  ammonium  sulfate,
limestone processes with or without recovery of gypsum, and
a red mud method. In the latter the mud discharged when alu-
mina is extracted from bauxite is the absorbent. It is feared
that the methods are not applicable to power plants because of
the following obstacles: generation of white  smoke, decrease
in the  diffusability of the smoke, and corrosion  inside chim-
neys. It is hoped these disadvantages can be overcome by a
dry method  now under testing.  In this method, a solid absor-
bent is contacted with a gas at 100-140 C and the absorbent
regenerated.

Present methods of dry desulfurization using activated carbon
are expensive because of the loss caused by the oxidation of
the absorbing agent, and they  are dangerous because of the
possibility of an explosion. Experiments  involving a variation
of the  dry  method are described. Using  high grade activated
carbon instead of semi-coke not only increases the  absorption
potential, but also requires much less equipment. The use of
super-heated steam as a desorbing agent lengthens  the life of
the carbon and also  prevents the possibility of an explosion.
The method economically removes sulfur dioxide gas at high
concentrations. Bench-scale plants  using this method  have
been successfully operated, but further research is necessary
before full-scale  operations can  begin. A flow chart of the test
plant adopting all of the described characteristics is given.

MEASURES TAKEN BY IRON AND STEEL INDUSTRY TO
PREVENT   AIR POLLUTION  AND  SO FORTH.  (Tekko
gyokai no sangyo kogai boshi taisaku). Tex in Japanese. San-
gyo Kogai (Ind. Public Nuisance), 6(10):578-586, Oct. 25, 1970.

The Iron and Steel Industry Association has established the
Industrial  Hazards  Countermeasure  Committee, which has
four special subcommittees: Air Pollution Prevention, Factory
Effluent, Industrial Wastes, and Factory Safety (which han-
dles high pressure gas, and so  forth.) A joint study  is  being
made by more than 10 manufacturers of desulfurization equip-
ment on the desulfurization of smoke issuing from  pulverized
iron  ore process stacks.  Joint research by  iron  and steel
makers is being conducted using desulfurizing equipment with
a capacity of 150,000 cu ft/hr, with a 3 million dollar research
fund. Measures taken by another steel mill include establish-
ment of a pollution prevention committee, watching of smoke,
dust collection review circle, liaison council with related or-
ganizations, and smoke control staffs. Various equipment used
by the iron and steel industry for blast furnace, sintering fur-
nace, LD converter, open hearth, and electric furnace control,
such  as  bag filters, coolers, cyclones,  centering chambers,
dust chambers, electric dust collectors, multi-cyclones venturi
scrubbers, stabilizers, washers,  wet filters, and scrubbers are
described. Chemical compositions of dust collected from these
furnaces are tabulated.  Measures for the prevention of sul-
furous acid  gas taken by the newly operating KM Steel Mill
are described, followed by those taken  by the newest KKK
Steel Mill (first firing in August, 1970). They include not only
prevention  of air pollution, but also prevention of noise,
prevention  of pollution  of sea  water, and  construction of a
green belt. Investment on anti- air-pollution spent by SY Steel
Mill up to 1968 was $33  million, with a monthly operating cost
of $133,000. The rate of investment on prevention of industrial
hazards, invested by 137 mills in iron and steel industry (as 01
Oct. 1969,  MITI), increased from 3.22% in 1965 to 4.44% in
1969.

METHOD  FOR  THE  SEPARATION  OF PYRITE  FROM
COAL.   (Verfahren zur abscheidung von Pyrit  aus Kohle).
Rept. 41/69, 19p., 1969. 7 refs Translated from German. Belov
and Associates, Denver, Colo., 23p., Feb. 23, 1970.
Investigations of untreated coal which were conducted in dif-
ferent countries indicate that the pyrite percentage of the total
sulfur content of coal is  so high that mechanical separation
could result in a significant reduction of the sulfur content
Separation is technically possible and economically feasible as
pyrite occurs at an average of 80-90% hi a particle size larger
than 20 micron. Wet methods (gravity and centrifugal separa-
tion,  gravity turbidity methods, and flotation) should have
preference  because  of their operational and throughput effi-
ciency.  In  connection  with  the  trend  towards  the  hydro-
mechanical production of coal, direct burning of mud in power
stations is discussed. The use of atomic  heat is being contem-
plated to reduce the cost of drying. The selection of installa-
tions for sulfur removal is discussed according to the particle
size region of interest. If the sulfur content of the initial coal
can be reduced by at least 30-40%, and if the operational costs
of the sulfur removal amounts to approximately 5 to 35 cents
per ton product,  then it is  profitable to provide mechanical
pyrite separation methods. (Author conslusions modified)

species reduce atmospheric concentrations of dust and of solid
and gaseous radioactive substances. In addition, they reduce
noise, prevent binding of  SO2, and increase the relative hu-
midity of air. Solid particles can be filtered  from the at-
mosphere by planting open stands of trees or shrubs. Dense
stands are  needed  for  gaseous  pollutants.  In  protective
plantings, the longitudinal axes have to run across the prevail-
ing wind direction. In areas without wind, e.g., towns, hot air
ascends and relatively cold air pours in from all sides, leading
to the accumulation of polluted air in the center that has to be
filtered by concentric plantings. The closer the forest strips to
the source of smoke, the  greater their effectiveness.  (Author

For the purpose of  recovering dilute sulfur dioxide gas, the
solubility of SO2 to various organic or mixed solvents was stu-
died. Sulfur dioxide gas was led through 50 ml of solvent  at 1
atm and  30  C. When the  solvent was saturated with the ab-
sorbed gas,  it was diluted by 10 liters of alkaline water. Dis-
solved SO2  from a certain quantity of solution was measured
by iodine titration. Among pure solvents, the SO2 solubility in-
creased in the following order: saturated hydrocarbon, water,
aromatic hydrocarbon, alcohol ester, ether, ring ether, fonna-
mide, DMF, and DMSO. In the case of mixed solvents, on the
other hand,  the solubility can be classified into a convex solu-
bility curve, linear  solubility curve, and  concav solubility
curve. When two polar solvents of  non-hydrogen bond are
mixed with each other, the  solubility shifts toward that of
higher solubility. As a result,  the  solubility curve becomes
convex, and sometimes  a maximum value shows up. The solu-
bility becomes linear when two solvents with little  interaction
are mixed together. When a good solvent is mixed with a poor
solvent with a hydrogen bond, such as water, the dissolving
power is  drastically  reduced and the  solubility shifts towards
that of the poor solvent.

EMISSION AND PERFORMANCE OF GASOLINE ENGINE.
(Gasorin  kikan  no  seino to  haiki  joka  gijutsu).  Text in

49(521):646-655,  Sept. 20, 1970. 14 refs.
Most automobile emissions are products of a high temperature
and high pressure combustion chamber. The formation of car-
bon monoxide and nitric oxide are explained by equilibrium in
the combustion  reaction;  the quench zone  in the combustion
chamber  yiel  unburned hydrocarbons. Carbon monoxide and
hydrocarbons can be oxidized in the expansion stroke or ex-
haust systems. Reduction  of nitric oxide and particulate emis-
sion  is  a serious problem  for exhaust control  techniques.
Although an exhaust thermal reactor and catalytic converter
have been developed, non-leaded fuel is necessary for their ef-
fective operation. A low  emission  vehicle should appear by
1975, but the power plant of the family car still may be the
gasoline engine.  In  the near future, fuel will  be  subject to
more severe restrictions to reduce the  pollutants  in exhaust
gas; as an immediate target, at  the risk of reducing  some of
gasoline's performance, it would be  made in such  a way that
emission of pollutants would be about 10% of the former level.
                         In 5 or 10 years, automobiles should hardly be a problem as^
                         sources of environmental pollution.

                         pass through a screen of water produces exhaust air of higher
                         purity and minimizes the  danger  of fires.  Enclosed  spray

                         constructed that the operator is supplied fresh air. Paint and
                         solvent separation is the same as in open booths. The recovery
                         of solvents is accomplished by absorption with activated car-
                         bon whence the solvent is expelled by steam. When the  emis-
                         sion of solvents into the atmosphere exceeds 10 kg/hr, then
                         the German law stipulates  the mandatory use of a thermal or
                         catalytic  combustion installation. The  presence in the  at-

                         esters makes catalytic  combustion inapplicable.  Combustion
                         takes  place at  650-800 C.  The advantage  of catalytic  com-
                         bustion is that it operates with higher concentrations and lower
                         temperatures.

TREATMENT OF DUST GENERATED AT IRON MILL.

(Japan Magnetic  Ore Screening Co.) Japan. Pat. Sho 43-29863.
3p., Dec. 21, 1968. (Appl. Feb. 1965, claims not given).
A  method is described  for recovering oxidized iron by adding
cement or plated lime  to the fine wet iron  dust participates
from the sedimentation tank, thus making it easier to  handle.
Even afte the dust from the sedimentation tank is dehydrated
with a filter, it  still contains 30% water  which  prohibits its
reuse. However, the dust mixed with cement or lime dries and
solidifies naturally, permitting reuse for sintering. Because of
the capillary action of  the small air spaces between the dust
particles  as well  as the water adhering to their surface,
mechanical methods are ineffective Evaporation by heat is too
expensive. Dust  from sticky ores and from the stacks of the
sintering mill can also be treated by this method, thus conserv-
ing useful resources.

A  review of the literature and preliminary experimental results
are presented for the kinetics of chemical reactions and physi-
cal process under  conditions of  chronological  and  spatial
changes  in  temperature.  Based  on  fundamental equations
which describe the course of such reactions, the methods used
to  determine the order of reaction, the activation energy, and
the frequency factor are discussed, and experimental methods
in  current use for determination of kinetic parameters are eval-
uated. Various  investigations and  results on  the  release of
water from salts  and hydroxides, the calcination of carbonates
and oxalates, reactions of metallic oxides and carbonates with
sulfur dioxide, and reactions on carbon surfaces are surveyed,
and the  application of the non-isothermal method to the ther-
mal decomposition of carboxylic acids  and polymeric  plastics
as  well as to the pyrolysis of natural substances (particularly
bituminous coal) is  explained. Chemical reactions  in a liquid
phase,  the  desorption  of  gases   from solids,  annealing
processes disturbed crystal lattices, and the emission  of exo-
electrons from metallic surfaces are also discussed. (Author

In connection with a new method for neutralizing sulfur diox-
ide in combustion gases by means of ammonia, the changes in-
duced  by SO2  in guinea pigs were examined and compared
with the effect of the  products  of the reaction of SO2 with
ammonia. The first group of twenty guinea pigs were exposed
to SO2 at a concentration of 2 g/cu Nm in a special toxicologi-
cal chamber; the second group of twenty were similarly ex-
posed to the  products resulting from the reaction of SO2 with
ammonia. The third group of twenty animals were exposed to
SO2 at a concentration of SO mg/ cu Nm for eight hours a day
for four months, and the fourth group of twenty to the reac-
tion  products of SO2 plus NH3  for a period of four months.
The  blood  of all the animals was examined for the level of
hemoglobin   number of  erythrocytes and  leukocytes,  the
colored indicator, and a percentage composition of leukocytes.
Disturbances of acid-base  equilibrium were investigated,  as
well as the  pH of blood taken fro left ventricle, the partial
pressure of carbon dioxide and the tola pressure of CO2 in the
plasma. Also determined was the total protein level as  the ac-
tivity of aldolase, lactic acid dehydrogenas and asparagine and
alanine aminotransferase. Urine contents of sugar,  protein and
morphotic components were  determined for pH.  Samples  of
liver and brain were taken after the animals had  been sacri-
ficed, and the activity of their enzymes was determined as wel
as those of the blood. The toxic activity of SO2 is multiple and
leads to the impairment of  the function of  several  organs.
Toxic action of SO2 is due to the disturbances of the acid-base
equilibrium brought about by the inhalation of acid products
and by the disturbances of ventilation resulting from changes
in the  respiratory system. The decreased activity  of aldolase
and  lactic- acid dehydrogenase  in the blood and tissues  in
cases of SO2 intoxication may interfere with the carbohydrate
metabolism,   thus   accounting   for   hyperglycemia  and
disturbances  of glycogen  synthesis in the tissues. Animals ex-
posed  to the reaction  products of SO2 with ammonia had a
statistically lower mortality rate. The chemica reaction  of SO2
with ammonia  reduces the  disturbances of  the  acid-  base
equilibrium observed in SO2 intoxication and eliminates the
enzymatic disturbances in the blood and tissues noted  in SO2
intoxication. (Author abstract modified)

An experiment was conducted to observe the influence of the
ionic  wind on the collecting force in the  corona  discharging
field  of an electric  precipitator. The  first  step  was  to  in-
vestigate the nature of the ionic wind in the corona discharging
field in the atmosphere. Only negative corona was used, since
electric precipitators only involve negative corona. One-pin, 7-
pin, or a cylinder electrode was used as the discharging elec-
trode, and a wire net  or a  plate was  used  as the collecting
electrode.  The distribution of ionic wind velocity  and that of
corona current density were compared and the  relationship
between ionic wind velocity and the applied voltage  was ob-
served. Within the discharging field (3-6 kV/cm) of an ordina-
ry electric precipitator there is  no saturation of ionic wind
velocity, althoug there were some fluctuations. Although ionic
winds could possibly lower the efficiency of a precipitator, de-
pending on the type of precipitators or dust to  be collected, it
might be very effective.

Used-up acid from  steel pickling baths is regenerated  by
dispersing  it in high turbulence reactors where the free acid
and water  are vaporized  and the iron chloride  is converted to
Fe203 and gaseous hydrochloric acid at 440 C  in the presence
of  oxygen  and  steam.  The extremely fine  iron oxide  is
separated  by a specially designed electrofilter which  in con-
tinuous operation separates 99 to 99.8% Fe203.  All parts of  the
dry filter  are, in spite of the high HC1 content  of  the gas,
made of steel which is accomplished by insulation of the filter
and by heating and rinsing of all insulators with preheated air.
Gas temperature  must never reach or fall short  of  the dew
point of the acid which,  depending on  the plant, lies  between
110 and  ISO C. The discharge  electrodes constructed in  the
form  of so-called Bicorona flat steel electrodes  account for  the
high  degree  of  iron  oxide  separation.  The  electrofilter
processes crude gas with a 20 to 30 g/N cu m dust content to a
residual dust content of 100 mg/cu m.

MODIFIED I-C ENGINE REACHES PROPOSED  1980 EMIS-
SION GOALS.  Automotive Eng., 79(2):20-23, Feb. 1971.
The stratified charge Ford Combustion Process engine almost
meets 1975 federal emission standards in an M-151  vehicle
and, by adding a commercially available catalytic converter, it
reaches 1980 goals. Stratified charge basically utilizes fuel effi-
ciently and thus produces .considerably less  exhaust pollution
than  a carbureted  engine  without controls. Very little fuel
reaches the walls of the cylinder, leading to reduced quenching
                        and less production of unbumed hydrocarbons. Lean overall
                        mixtures minimize formation of carbon monoxide and nitrogen
                        oxides. The correct amount of air for minimum emissions from
                        this engine is an almost constant air/fuel ratio of 17-18/1. Mid-
                        air quenching and temperature control are discussed. Basics of
                        the Ford Combustion Process are described,  including timing
                        for both spark and ignition. The Texaco Combustion process is
                        also described, as well as turbocharging.

                        For many technological operations  in ferrous metallurgy, no
                        technical solutions have yet been  found  for preventing the
                        release of dust. An immediate task is the development of a
                        mathematical description of  the  aerodynamical processes of
                        propagation of dust from point and linear sources for different
                        air currents. The adopted systems of dust elimination, aspira-
                        tion, and ventilation and the  apparatus used require thorough
                        mathematical investigations. The  time has also come for the
                        development of a  single organization framework for the dust
                        ventilation services for metallurgical enterprises,  and the or-
                        ganization of planned training of cadres for them by a system
                        of technical training at the works.

                        An effective disposal method for the ash produced from in-
                        cineration of sewage or industrial waste sludge is described. In
                        the dewatering or  dehydration of sludge or the like by means
                        of a vacuum  filter, coagulants such as iron  chloride  or iron
                        sulfide and slaked lime are generally added to the sludge to
                        cause flocculent masses to form. Thereafter the sludge is fil-
                        tered to remove the solids  and incinerate them. However, ash
                        is  produced in large quantities as a result  of  the incineration,
                        while bad odors and poisonous gases are also generated when
                        heavy  oils  or  the  like  are utilized as auxiliary fuel. In the
                        present method, sludge treated with coagulants and filtered for
                        dehydration is  incinerated at  800 C or higher. By means of a
                        cyclone,  the ash is separated into  that chiefly composed of
                        calcium oxide and that composed of ferric oxide. The CaO is
                        recovered and used as coagulant to induce flocculant masses
                        to form in the sludge to be  filtered;  the Fe203 ash is mixed
                        with water and used as a reaction agent for hydrochloric acid
                        and sulfurous acid gas generated from the incinerator, thus
                        forming iron chloride. The  solution is then separated into solid
                         and supernatant. Only the  acid supernatant containing iron is
                         recovered and utilized as a  coagulant for the raw sludge.

Experiments were carried out on a coal bagger with wet dust
suppression. The efficiency  of dust  suppression with  and
without a wetting agent in the water was tested. The wetting
agent Lessageene Z 100 was added in quantities of about
0.08%. Dust supression was clearly  improved by use of the
wetting agent and a spraying speed of 100 1/min. Far more dust
was  suppressed under these conditions than by double spray-
ing the amount of water, i.e., 200 1/min without the wetting
agent.  This applied to  the entire range of grain sizes of dust
particles, fine as well as coarse.

THE  BEHAVIOR  OF SULPHUR   DURING  THE  FIRING
PROCESS  OF  CEMENT CLINKER.   (Das  Verhalten  des

89(5-6):124-130, 1965. 19 refs. Translated from  German. Belov
and Associates, Denver, Colo., 24p., Dec. 18, 1970.
The  sulfur dioxide concentration in flue gas from cement fur-
naces is considerably lower than could be expected according
to the  sulfur concentration of the raw materials  and the  fuel
used in the firing process. In laboratory experiments, the reac-
tion  of calcite  and SO2 was tested; in  industrial  experiments,
the alkali- sulfur balance for various furnaces was established.
In a temperature range of 400-500 C, calcite reacts with SO2
and leads to the formation of calcium sulfate. The conversion
rate  can  be increased by an increase in temperature, enlarge-
ment of  the specific surface  area of the introduced powder,
and by the presence of water vapors during the gas phase. At
first, a phase contact surface reaction occurs;  after enclosure
of the  calcite-  kernal by CaS04, diffusion reactions become a
deciding  factor of speed. The SO2-emission and the alkali and
sulfur utilization of two Lepol furnaces, three gas suspension-
heat exchanger furnaces and  one shaft furnace using coal or
oil as fuel were  determined. It was shown that 79-98% of the
sulfur output in the clinker occurred as sulfate. A nearly linear
relationship between the alkali-sulfur trioxide ratio in the fur-
nace gas phase and the  SO2-emission  was found. This  SO2-
emission can be reduced in the furnace gas phase by an in-
creased amount  of  alkali. By gas suspension-heat exchanger
furnaces, the SO2-emission can be reduced to below 160 mg/N
cu m by the addition of  a mill drying plant which is  powered
by the  flue gases. (Author summary modified)

Aspects of natural and technological control methods for air,
water,  and noise pollution are discussed, with suggested topics
of research given for each. Plants have an ability to  function
as air purifiers, within  the limits of their toleration to various
individual  pollutants.  The  effects  of  such pollutants  as
ethylene,  carbon monoxide, sulfur dioxide, and  fluorides on
plants are described. The purifying action of water plants and
bacterial beds  has  application to water purification  in treat-
ment facilities as well as in natural fresh water bodies. Purifi-
cation processes within the bed of a lake are also considered.
Control methods for suspended  particulates  from  industrial
and domestic sources including separators, filters, and electro-
static precipitators, are briefly noted, while the various design,
operational, and control  device techniques now under study
for control  of  motor vehicle  emissions, particularly  storage
batteries for electric propulsion, design modifications and cata-
lytic afterburners, are considered at length. Also discussed are
pretreatment of industrially polluted waters, potential uses of
water treatment sludge,  and means for preventing and/or ab-
sorbing noise in residential, business, and industrial areas.

The possibility  of improving the design of the nozzles used in
benzole scrubbers was  investigated  in  order  to  give  better
atomization and increase the volume of liquid absorbent with
installing more  nozzles.  By adjusting the live sections of the
spray nozzles,  it has been possible to increase the wash  oil
throughput  by  11%. The modernized  nozzles  distribute the
spray more uniformly over the top of the grid packing in the
scrubber, and their useful life is much longer. The extra power
consumed by the new nozzles is  within the capacity of the
pumping equipment already  provided.  (Author  conclusions

bers Convention, Essen, West Germany, Dec. 17, 1968.)
Three  scientific innovations in coal processing  are  described
and  evaluated: the  whirling layer  heating  system;  mag-
netohydrodynamic (MHD) energy  conversion; and coal  com-
bustion with process heat from a nuclear reactor. The efficien-
cy of the whirling layer heating system is brought about by the
complete combustion of fine coal (granulation 0-3 mm) kept in
suspension in warmed air. Desulfurization of the smoke gas
can be achieved by the addition of fine grain limestone to the
coal. This system can be expected to lower electricity produc-
tion costs  by approximately 10-15%. A pilot plant  will start
production in 1970. The MHD energy conversion system is ad-
vanced far beyond  traditional techniques. It depends  on the
ionization of hot smoke gas (above 2500  C)  which is then
driven  through  an electromagnet. The loss of temperature and
pressure is converted into electric current. The  MHD genera-
tor used as an aggregate to a conventional power plant will in-
crease  total efficiency as  much as 60%, thus reducing electrici-
ty production expenses by 12-25%. Coupled with a continuous
coking plant, the MHD generator would lead to coke produc-
tion with no by-products  except the production of electric cur-
rent. A prototype MHD generator is in use in the U.S.S.R. The
functional realization of the whirling layer heating system and
the MHD  generator can be expected in the mid-1970's, at the
earliest. The method of carburetion of coal with process heat
from nuclear reactors will be used for the economical produc-
tion of raw material for the chemical  industry  from  coal,

synthesis gas, or hydrogen. The advantage of this method is
that 30,40% of the coal which would otherwise be necessary
for the production of fine synthesis gas is replaced by less ex-
pensive reactor heat. Also there is no necessit  for using ox-
ygen, as is required  for traditional methods of  coal carbure-
tion. Technical realization of this method is far off, but the
goal is reachable. Carburetion through nuclear heat can be ex-
pected by the 1980's.

The mechanism of  oxidation of C2-C3  olefins, butane,  and
carbon  monoxide  on  an aluminum-copper-chromium  oxide
catalyst was  studied by  a  two-stage calorimetric method at
200-900 C. These temperatures correspond to those involved in
the detoxification of exhaust gases of gasoline engines. Carbon
monoxide and butane were oxidized on the catalyst surface at
both low and intermediate temperatures. Only at 600 C did a
gas-phase oxidation appear, and it proceeded independently of
the presence of the catalyst. Degradative oxidation  of the
olefins took place on the  catalyst surface at low  temperatures,
but a  heterogeneous-homogeneous reaction involving a  sur-
face-volume  mechanism  occurred at intermediate  tempera-
tures. At high temperatures, oxidation of the olefins proceeded
mainly in the gas phase.

An improved method for the removal of sulfur dioxide, and
more  detailed information  about the reaction  of SO2 with
synthetic  activ  manganese  are  presented.  Five kinds  of
synthetic MnO2  and one kind of natural MnO  were used as
samples. The  velocity  of their reaction with SO2 was  mea-
sured with a thermobalance,  and the change in reaction time
measured from the increase in weight. The curves of the log of
the pressure  of SO2 versus reaction time  show that for the
chemically  synthesized samples  which  have a larger surface
area, the reaction velocities with SO2 are fairly  rapid. In fully
crystallized samples or natural samples, the reaction velocities
are comparatively slow.

                        method of treating industrial waste water and at the same time
                        preventing air pollution were investigated. The  exhaust gas
                        used was a mixture of sulfur dioxide,  air, and nitrogen gas,
                        which  was  passed  through a layer of vanadium  catalyst to
                        produce sulfuric acid by a contact method. The SO2 was con-
                        verted to  sulfur trioxide. A mixture of red sludge, open-hearth
                        furnace slag, and  5%  kaolinite was made into a  paste, ex-
                        truded from & large injection tube, and then dried. The same
                        process was used for a mixture of aluminum oxide, obtained

                        minium, and 20% kaolinite. The  products were reacted with
                        the exhaust gas, and the soluble component thus obtained was
                        fade-tested using a direct orange dye. The results of the SO2
                        removal and of the fade tests are tabulated.

                        The process described separates  hydrogen sulfide  and sulfur
                        dioxide from  gas  emanating  from the Claus process, and

                        of coal, oil, or other carbonaceous material for the synthesis
                        of ammonia. The gas  is at temperatures from ISO to 400 C
                        brought in contact with ferric oxide fixated on a base material
                        which  contains from 10-40% iron trioxide. Ferric sulfide forms
                        which  is  subsequently oxidized by hot air to  sulfur,  ferric
                        oxide  is  recovered.  The reactive mass forms a mobile bed
                        which  is continuously being recycled between the contact and
                        the regeneration zone.  In the  contact zone at least part of the
                        SO2 reacts with the ferric sulfide, also yielding ferric oxide
                        and elementary sulfur. The desulfurized gas escapes into the
                        atmosphere. The vaporized sulfur  contained in the gas  issuing
                        from the  regeneration  zone is condensed and deposited in a
                        cooling chamber. The process can be so modified that it takes

                        To determine  optimum conditions for black liquor oxidation,
                        aqueous solutions of hydrogen sulfide, methyl mercaptan, and
                        their salts were oxidized by aeration at various flow rates and
                        temperatures and within a wide range of pH. For all solutions,
                        the  rate of oxidation was determined mainly by temperature
                        and area  of contact between  the solution and oxidizing agent.
                         Both hydroxone and hydroxyl ions had a catalytic action  on

                        apparatus. Temperature should be 80 to 100 C and  pressure 4
                        to 5 kg/sq cm. Under these conditions, the rate of oxidation is
                        determined by the value of the pH and of the ionic salt of the
                        bkck liquor. The final  pH must not be lower than 12.5, as at a

DIRECT DESULFURIZATION  OF HEAVY OBL BY CIRCU-
LATION TYPE  UPWARD  FLOW  REACTOR.   (Junkan  gata
uwamukiryu  hannoki ni  yoru  juyu no chokusetsu datsuryu).
Text in Japanese. Preprint, Japan  Society of  Chemical En-
gineering, 5p.,  1970.  2  refs. (Presented at Japan  Society of
Chemical  Engineering,   General Symposium  9th,  Nagoya,
Japan,  Nov. 25-26, 1970, Paper B-3-4.)
Heavy  oil direct desulfurization methods used  industrially in
Japan  include the RCD Isomax process,  the  Gulf-Residual
hydrodesulfurization  process, and other fixed-bed types. While
the heavy oil fluidized-bed technique solves the problems in-
volving reaction  heat control  and catalyst  life inherent  in
fixed-bed methods, it increases  the quantity of heavy oil recir-
culation in order to liquefy  the catalyst. This results in a near-
perfect mixture flow, because the reaction efficiency is lower
compared with piston flow. If the old catalyst can be removed
from the bottom of a catalyst layer standing still in the upward
flow without stopping the operation, it will not be necessary to
liquefy the catalyst.  And therefore the quantity of heavy oil
recirculation  can be  kept  to  a minimum, making the  flow
similar to a  piston flow and advantageous for higher reaction
efficiency.  A moving-bed  desulfurization (MDS)  process is
described  in which   a  stationary  layer of  spherical pellet
catalysts are partially replaced  with fresh catalysts fed inter-
mittently while the old catalyst  is removed at the bottom. The
process permits  a higher reaction  efficiency due to a lower
heavy oil recycle ratio and  a small high temperature separator
and  oil circulation pump due  to  reduced oil  circulation. A
larger quantity of catalyst can  be put in the  reactor, and the
fresh catalyst installed from above moves downward as the
old catalyst  is removed from  the bottom  so  that  the  new
catalyst may be kept in at all times. Since the  raw heavy oil
flows upward to contact the older catalyst in the bottom of the
catalyst, the deleterious substances to the catalyst are first fil-
tered by the older catalyst. A cooling device required for con-
trol of  the reaction heat, as with the fixed bed type is the main
disadvantage.

At rendering factories, the  raw  material should be placed in a
concrete  pit, 2-3 m underground, with a V-shaped bottom. At
the bottom,  a screw conveyor  is installed through which the
raw materia is sent to the crusher. The pit can be equipped
with a  lid. Although  a stone separator and metal detector can
eliminate stone, gravel, and  metal,  such things as vinyl, cloth,
and rope have to be eliminated by hand. Dead animals, animal
bones,  and large fish, ar put into the hasher before  they are
put in a cooker.  These machine  save labor, and the processes
can be  air tight. The  continuous cooker is operated at 80-90 C
for 10-20 minutes for fish offal.  Animal bones and feathers are
placed  in a dry rendering plant. After cooking,  a screw press
removes 30-35% of the water from the fish offal and the fish
cake is dried. The water is  desludged. The animal bones and
feathers are  dried to  decrease their water content to 6-10%. If
an expeller is used for the fish offal to decrease the water  con-
tent  to  45-55%, the odor is decreased. The water removed
from the offal should be utilized as fish soluble, as it contains
3-6% protein. The  odor  can be treated  by combustion, ac-
tivated coal,  ozone, or oxidation catalyst methods, a neutral-
izer or masking method, or dilution. The cost of these methods
is calculated.

DESIGN OF  AN ELECTROSTATIC  PRECIPITATOR  USING
MODELLING  AND SIMULATION  TECHNIQUES.   Proc.
North Eastern Regional Antipollutio Conf., Kingston, R. I.,
1969. 7 refs. (July 22-25.)
Six  mathematical models are developed for three different
flow  regimes encountered in  plate and  tubular electrostatic
precipitators.  The flows considered are plug, laminar, and tur-
bulent. In each case, the model is solved for the height of the
precipitator necessary  to  ensure 100% collection  efficiency.
The  calculated results from  a digital  simulation are compared
with  those obtained using  standard design techniques.  The
results of the simulation can be used to evaluate the effects of
new  and/or different precipitator geometries, aerosol  proper-
ties,  and electrostatic  conditions. This  work may serve as
guide to the proper  design  and selection  of  electrostatic
precipitators.

43(ll):2556-2557, Nov.  1970. 5 refs.
The  catalytic conversion of  gaseous chlorine to  hydrogen
chloride  was  studied using methane or propane as the reducing
gas and the following catalysts: powdered brick,  alumina gel,
Fe2O3 on alumina gel, and Cr2O3 on alumina gel. The chlorine
concentration of the gas was maintained at about  1%.  Almost
complete conversion of chlorine to hydrogen chloride was ob-
tained at about  250 deg when propane  was used  in the
presence of chromium  oxide on alumina gel. The temperature
of the gas entering  the reactor need not be above 150 deg. It
can be lowered substantially below this if the process  is con-
ducted in a fluidized catalyst bed. The catalytic process thus
provides a radical solution to the problem of decontaminating
waste gases from chemical and metallurgical industries, espe-
cially gases from magnesium production.

The  capacity  of heavy fuel oil burners has been increased to 9
t/hr,  which allows large plants to be equipped with fewer bur-
ners. Continuous regulation can maintain soot-free  combustion
with  the smallest air surplus. Because of increased air pollu-
tion  concern, oil gasifiers,  blue flame burners,  combusters,
and semi-combusters are gaining importance. Also, the familiar
principle of  water-in-oil  emulsions for  soot prevention  has
gained great interest; this  functions when the water droplets in
the fuel oil are smaller  than the smallest atomized oil droplets.
With the aid  of thermally decomposed water in the flame, the
air surplus can be reduced without soot formation, less sulfur
trioxide  develops, and  the danger of low-temperature corro-

sion is reduced. Water-containing waste oils can be burned as
emulsions if they contain more than 50% combustibles. If this
is not the case, fuel oil or gas must be added. Burners which
take two or three different types of fuels have come increas-
ingly into use. Since natural gas is now preferred over the fuel
oils, the natural gas prices will rise.

ELIMINATION OF  OXIDES  CONTAINED  IN  CERTAIN
RESIDUAL INDUSTRIAL GASES.  Preprint, National Indus-
trial Nitrogen Office (France),  1968  (?).  Translated   from
French. 7p.
The determination of nitrogen oxides is difficult in  the course
of nitric  acid synthesis  by ammoniac  oxidation.  Recently  a
process has been developed which destroys nitrogen oxides by
reducing  them  catalytically at  about 400 C.  However, this
requires large investments and a lot of equipment, and it is dif-
ficult to  resolve this problem  economically because of the
large quantities of water vapor in the residual gases. A new in-
vention washes the gases at  ordinary temperature and  pres-
sure, is more economical, and emits a nitrogen dioxide content
of less than  the toxicity threshold (10 ppm). Ammonia  solu-
tions can be used to purify gases with sulfurous and anhydride
by   reacting   to   form   ammonia   sulfate.   The  molor
bisulfite/sulfite ratio  of  the washing solutions  should not ex-
ceed 0.1  to 0.4. The gas flow  can be 1300 to 1500 volumes of
gas  per useful volume of washing. Treated  gases  are practi-
cally odorless and colorless; a mist of white vapor can  be
eliminated by electrostatic precipitation. Then ammonia sulfate
can be crystalized and extracted.

Because  of the high affinity that potassium or cesium seeding
materials have for sulfur and their easy regeneration, sulfur
can be   profitably  recovered  from  an   open-cycle   mag-
netohydrodynamic power plant. The sulfur with hydrogen (as
hydrogen sulfide) can be removed from the seed-slag mixture,
thus leaving a sulfur-free effluent gas. A slag-seed mixture was
simulated and reacted with hydrogen. Then the sulfur removal
rate was calculated from a formula. A  kinetic model was for-
mulated from the experimental observations.  The reaction rate
and maximum conversion level  depended on  temperature. The
model was applied to the  regeneration of alkalized alumina;
similar techniques for regenerating alkalized alumina can be
used to remove sulfur from seed-slag mixtures. The economic
feasibility of sulfur removal from recycling seed-slag mixtures
was also discussed.

                        An experimental bag filter for collecting fine carbon black par-
                        ticles  from a  carbon black/gas mixture was  developed with
                        two filter  sections consisting of cells for purified  and unpu-
                        rified gas. The cells were formed by sewing together panels of
                        fabric and stretching them on a special frame. In the upper
                        part of the filter, a purified gas collector contains air-distribut-
                        ing tubes with nozzles on the same axis as the cells for the pu-
                        rified gas. The air-distributing tubes are connected, through an
                        electromagnetic valve, to a receiver of compressed air. When
                        a certain  hydraulic pressure  is reached, the  electromagnetic
                        valve  is activated and bursts of compressed  air pass into the
                        distribution tubes. The jet of air ejects the purified gas in the
                        collector  into the cavity  of the  shell.  When  the fabric is
                        shaken, simultaneous back-flow occurs. During nine months of
                        operation, no  clogging of the cells with carbon black was ob-
                        served. The average  degree of contamination at the exit from
                        the filter was  0.01 g/cu m, and the optimum rate of filtration
                        was 1.0 m/min. The filter can be used to  purify air'at tempera-
                        tures not exceeding 70 C.

                        found that absorption was not efficient. The use  of packed
                        towers requires that the flow rate not exceed one m/sec. Each
                        packed tower must  be operated with an alkaline solution; a

                        may form insoluble  products with the scrubbing fluid. Dust
                        collectors should precede the packed tower in such cases. It is
                        also advantageous to force the  gases through the tower, to
                        avoid  some of the problems which its moveable  parts may

The concentration of a dust is represented by weight (g/cu m)
in unit volume. If the dust is  extremely dilute, particle count
(particle/cc) per unit volume is employed. The Air Pollution
Control Act sets standards for dust concentrations according
to source classification. Grain size  distribution is represented
either by frequency or by integration. Microscopic, screening,
pipet, sedimentation,  or light  transparency  methods are  em-
ployed for the determination of particle size distribution. True
and volumetric specific gravity is defined. Adhesivity,  electri-
cal resistance, angle of friction, particle configuration, surface
roughness, hygroscopic properties,  corrosion resistance,  tox-
icity and explosivity,  and dynamic  characteristics of particu-
lates are described. Free fall velocity in atmosphere  is  dia-
grammatically shown,  together with  the  Cunningham  cor-
rection. Normally the gas temperature is extremely high, being
200-600 C at the dust collector. With dust collectors utilizing
gravity,  inertia,  or   centrifugal  force,   particle velocity
decreases at high temperatures because  of the  increase in
viscosity. Also, the pressure loss increases,  resulting in lower
collector efficiency. The recently developed high-temperature
bag filter is usable up to 300 C. Estimation of the gas quantity
to be processed, water content, and the effects of sulfuric an-
hydride are also explained.

Third generation dust filters (1965-1975) for compact continu-
ous filtration, filter housings with removable filter panels for
500 to  20,000 cu m air/hr, classification of filters by their  per-
formance,  the systems concept  of air filtration,  the  trends
discernible in filter development, electrofilters, and the filter
supply situation and their importation into East Germany are
reviewed. Third generation  dust filters have a frame  size of
710 by 460 mm, process 3000 cu m air/hr which corresponds to
a flow  velocity of  2.55 m/sec. Filter  assemblies come in 24
sizes with the largest having a capacity of 420 000 cu m air/hr.
The filtering material  consists of  a  fleece of polyester  and
polyamide fibers lined by malimo gauze tighly stretched over
rollers in several folds within the filter frame. Dust-laden filter
material,  replaced by fresh  fleece by winding a roller, is
descarded. Aerosol filters are  currently being  officially) tested
by means of radioactively marked  aerosols. The AFI code is
not used in the G.D.R. A new system is proposed which classi-
fies filters by their separation power of silica dust, oil fog, and
radioactively marked aerosols and stipulates the test procedure
to be  used  in each case. The trend  is  away from reusable
towards  disposable filters,  even though  the  cost is  higher.
Electrofilter production and use has declined because of their
frequent malfunctions,  even though  their  usefulness  in  fine
dust removal is generally  recognized.  The  importation of
foreign, even of superior filters is being discouraged.

WHAT DO W'  MEAN BY TECHNOLOGY FOR THE  MAIN-
TENANCE OF CLEAN AIR?  (Was versteht man  unter Luf-
treinhaltetechnik). Text in German.  Wasser Luft Betrieb, Son-
derheft PRO AQUA - PRO VITA, June 1971, p. 46-47, 14 refs.
The technology for  maintenance of  clean  air  comprises all
methods for removal of solid, liquid, or gaseous  emissions.
Measures reducing emissions  start with  the  selection  of  the
raw  material  and  include modifications of the  production
process,  construction and dimensioning of waste-gas exhaust
systems, equipment for cleaning the waste gases, and all facili-
ties for discharging the clean waste gas. Monitoring and equip-
ment maintenance  are also control measures.  The operating
range of dust collectors covers dusts  with grain sizes of 0.01
micron to dusts with sizes of more than 1000  micron. Dust
concentrations in  waste gases can be easily reduced  to  150
mg/cu m for nontoxic dusts and to less than  100 mg/cu m for
toxic dusts. Settling chambers are primarily used for prelimina-
ry collection of  large-grained  dust. The collection  mechanism
of filters is to a large extent still unknown. It is assumed that
impaction of large particles  occurs  and that fine dust is
retained through diffusion and electrostatic forces. The  collec-
tion  efficiency of mechanical dust collectors can be improved
by  enlarging  the  mass of the  dust  particles.  This  can be
achieved  by  binding the  particles to a fluid. Electrostatic
precipitators  are preferrably used for cleaning large waste gas
flows. Gas-cleaning methods are based on physical processes
or  are  connected with  chemical reactions.  The physical
methods include dilution,  condensation,  absorption, and  ad-
sorption; the chemical methods, oxidation processes.

REPORT OF THE STUDIES OF THE PREVENTION OF OF-
FENSIVE ODORS  (NO. 3). (Akushuboshi ni kansuru kenkyu
hokokusho. (Dai HI ho)). Text in Japanese. JESC-42-076. 82p.,
March 1968.
Environmental pollution problems in  every Japanese prefec-
ture  include  offensive odors from  fish  meal plants,  fish
manure mills, and factories for drying chicken droppings. The
condition of deodorizing equipment installed in such factories,
methods for measuring offensive  odors, and future counter-
measures were surveyed.  Eight  models of deodorizing equip-
ment were  tested. Construction  and maintenance costs of
these models  are  tabulated along  with data for currently in-
stalled equipment. Since  deodorizing equipment  associated
with  a single method does not  effectively  eliminate  odors,
deodorization by a combination of methods was  postulated.
Gas  chromatography was  adopted as the main method  for
measuring an offensive odor and as the method for collecting
samples. Sampling  amines, mercaptans, and organic acids by
glass-bead tubes is also described, and results are reported for
actual measurements. Based on  investigations of the sources
of offensive  odors at 25 mills, the chief  constituents of basic
offensive odors are ammonium and trimethylamine. Other low-
grade amines were scarcely observed. The usual rate  of am-
monium  and  trimethylamine in emission  sources is between  1
to 10 and 10 to 1 in fish meal plants and one to one in the fac-
tories for drying chicken  droppings. In  some cases, exhaust
concentrations exceeded 100  ppm. Six  types of deodorizing
equipment were  observed,  but  almost  no factory  had  a
satisfactory blueprint for eliminating pollution. The economics
of proposed measures are discussed.

dispersed light. Sample gas was passed into the tube from the
lower opening and through the burner at the speed of 7 m/sec;
the light continuously scattered at the narrow point of the tube
and  reached  the  upper part  of the  water jacket which en-
veloped the tube. The intensity of the light was photoamplified
and was sent to a penrecorder. At the test site, methylmercap-
tan was discharged for five minutes at a height of two meters
from  the ground,  100  meters wind way from the measuring
point. The record showed a wave  pattern with six  or seven
large  peaks,  probably  due to the  breeze.  But  the  test was
deemed successful. In the United States, the Kraft Pulp Mill s
deodorization process by ozone is an example  of successful
treatment of industrial odor problems. In the process  of chemi-
cal digestion  of pulp, hydrogen sulfide and  methylmercaptan
are emitted and create odor. According to a study, 1000 kg of
pulp creates 114.2 g H2S and 824.1 g of mercaptan at the Kraft
Pulp Mill. The main sources of emissions are the stacks of the
black liquor combustion furnace; discharge from the digester;
waste  gas  from  the  blowdown;  and  the  non-condensable
materials from the evaporator and vacuum pumps.  Oxidation
of the gas from the black liquor stack solved that  particular
problem, but  the  main source of odor was the blowdown
which oxidation did not help. More  recently, waste gases at
this mill are treated through condensers where ozone is added
to the gas at the entrance and exit, and has proved successful.
The duration of gas-ozone contact is also important, and a 2.2
sec exposure gave the best result.

DESULFURIZATION OF STACK GAS BY MKK PROCESS.
(MKK ho ni yoru haien datsuryu). Text  in Japanese. Netsu

23(8):42-45, Aug. 1971.
In the MKK sulfur control process, an absorption liquid at a
pH of 12 is run countercurrent to the direction of flow of the
stack gases. The absorption device is a multi-stage jet scrubber
which utilizes  sodium  hydroxide  or sodium sulfite  as the
scrubbing solution. The absorption liquid is  removed at a pH
of five and sent to a reaction  tank where lime is added. NaOH
is produced and calcium sulfite settles out. After filtering, a
good gypsum product can be produced. This method is suita-
ble for 20-100 t/hr boilers.

(Akushu boshi no kihonteki hobo). Text in Japanese. Yosui to
Haisui (J. Water Waste), 13(9):1079-1090, Sept. 1971.
Of  various  basic methods  of deodorization,  those  by  (1)
decomposition or solution and concentration or absorption; (2)
chemical deodorants; (3) adsorption;  (4) ion  exchange; and (S)
oxidation are discussed  in detail.  The first method includes
water scrubbing apparatus of simple water  washing; columns
packed with  coke, Raschig rings, pipes, or ceramic balls; step
towers  such as  multi-perforation  steps,  mesh-steps,  lattice-
steps, air-jet steps, umbrella-steps, and floating balls; and spe-
cial absorption towers such  as waterfilm types and  cyclone
scrubbers. Temperatures  for concentration  of various odor
producing  elements  are  given.  Chemical  deodorants are
discussed according to various classifications such as powders,
liquids, and  gases; organic and inorganic methods; methods
such as direct application, surface covering, aerosol contact,
flow-through; and mechanisms such as psychological (mask-
ing, neutralization), physical (solution, adsorption), and chemi-
cal (concentration, superimposition, oxidation, reduction, and
                         disinfection). Tables of deodorization effects by direct and in-
                         direct applications of inorganic deodorants and deodorization
                         mechanisms of organic deodorants are given. Tables for the
                         adsorption capacity of  activated carbon  for various  odor
                         producing elements, room  sizes that one  pound of activated
                         carbon will deodorize for one year, and necessary amounts of
                         activated carbon per person per year for various classes of
                         facilities are included. A table is presented showing the effec-
                         tiveness of various ion exchange resins. Various methods of
                         oxidation, such as ozone, chlorine, combustion, and bacteria
                         are discussed.

                         A  method is  described  of scrubbing  power plant flue gases
                         with ammonia, thus separating out 93-97% of the sulfur diox-
                         ide and sulfur trioxide  as  ammonium sulfite, bisulfite, and
                         sulfate. These  waste products  are  treated  with lime for
                         recovery of the ammonia which can then be recirculated. The
                         sulfur-containing acid residues  are converted  into insoluble
                         calcium sulfate which can be disposed of without danger. If no
                         utilization of the chemical  end  products is foreseen, this is a
                         very economical method for the control of sulfur oxides. The
                         power plant St. Ouen has a pilot plant operating on this princi-
                         ple,  which has been modified for recovery of the SO2 as a

                         A  method of flue gas desulfurization from coal power plants
                         by ammonia is described, in which 90% of the sulfur dioxide is
                         absorbed. Ammonia is recovered by lime during the formation
                         of a dehydrate of calcium sulfate of high purity. The purity in-
                         creases if lime milk is used instead of lime. About 80% of the
                         ammonia is recovered. The process of ammonia regeneration
                         is cheap and simple.

                         The poisoning of  desulfurization catalysts  was investigated.
                         Samples were taken from the middle of a two m long cobalt-
                         molybdenum-alumina catalyst employed for the hydrodesul-
                         furization of Kafuji oil in a fixed-layer reactor. X-ray analysis
                         revealed nickel deposits  to  be distributed uniformly throughout

                         ty of the surface of the catalyst. No difference was  observed

1000 hours. The rate of deposition was considered linearly pro-
portional to the concentration of the compounds, and the reac-
tion to be reversible. Once deposited, the compounds did not
escape from the surface, nor move around on the surface or
inside the catalyst. The deposition process is independent of
the hydrodesulfurization process. Based on these assumptions,
a theoretical model was derived of the deposition process. The
reactivity of vanadium  with the catalyst was greater than that
of nickel, while the diffusion coefficient was lower for vanadi-
um than for nickel.

DESULFURIZATION OF  SMOKE GASES.   (Obesserivaniye

Problems (USSR), 1970. 17 refs. (Presented at the Seminar on
Desulfurization of Fuel and Flue Gas.) Translated from Rus-

1971.
When heat and electric power stations, designed to burn coal
containing about  2.5%  combustible sulfur, began to be con-
structed in  Moscow and other industrial centers in the  1930s,
research work was started on a broad  scale toward the control
of sulfur dioxide  emissions.  Methods  were tested in large ex-
perimental and industrial  installations. Catalytic  oxidation of
sulfur dioxide  produces sulfur trioxide in an aqueous medium
in the  presence of a manganese ore. An  ammonia-autoclave
method is used to absorb  SO2 by an aqueous solution of am-
monium sulfite-bisulfite with the subsequent decomposition of
spent solutions in an autoclave to ammonium sulfate and ele-
mentary sulfur. The limestone method is based on the sorption
of SO2 by suspensions of lime or active limestone, producing
a mixture of crystals of calcium sulfite and sulfate. The mag-
nesite method uses  the absorption of SO2 by suspensions of
magnesium oxide, producing crystals of magnesium sulfite Mg-
S03.6H20, which are roasted by the hot smoke gases at 800-
900 C. Modifications of these methods were  also tested, and
additional procedures and costs are indicated.

WET-TYPE DUST  COLLECTOR  UTILIZING CONDENSA-
TION.  (Gyoshuku  o  riyo shita shisshiki shujinki soriboru).
Text  in  Japanese.  Sangyo  Kogai  (Ind.  Public  Nuisance),
7(10):573-574, Oct. 1971.
A new, wet-type dust collector consists of a casing, and  many
venturi pipes arranged  in parallel in the casing, and water jet
nozzles at the both ends of the pipe bundle. Dust-containing
gas flows into the casing and into the narrow part of the ven-
turi pipes where the  speed and pressure drop. Vapor conden-
sation occurs and dust particles are covered  by a thin liquid
film. The turbulent air current created  at the narrow throat and
the difference  in sizes  and weight of the particles cause colli-
sion of dust particles and water drops, enlargine each particle.
As they leave the venturi pipes, they are sprayed by the water
jet and large dust particles  drop down as sludge. Clean gas
goes through  a vapor separation apparatus and is discharged.
This apparatus  is particularly effective for collection of large
quantities of small particles (down to 0.04 micron). The con-
tact of the  gas and jet liquid is great and uniform, and toxic
gases such as sulfur dioxide and fluoride can be absorbed easi-
ly. The decrease in flow speed or quantity has no effect on the
collection efficiency. The circulation of the jet water is  easy,
and the maintenance of the spray  nozzle  is easy because of
the large opening. Wearing from friction is limited because of
the slow speed of the gas.

COLLECTION AND ELIMINATION OF DUSTS. (Shujin and

Definitions of stack gas, dusts, particulates, emission sources,
air  quality standards, measuring methods of suspended par-
ticulates,  effects  of dusts  on human health, emission  stan-
dards,  and various methods of dust collection  are reviewed
with references to laws and statistics. Dust collection devices
include settling, momentum, centrifugal  separation, scrubbing
(pool, pressure, and wet cyclones), sound wave  (condensation
and particle growth), filter (surface and internal  filtering), and
electrostatic precipitator methods.  Various filtering materials
are reviewed with regards to temperature, acid  resistance,  al-
kali resistance, durability, hygroscopicity, and costs. Compara-
tive efficiency and costs of various types of collectors are as
follows: settling chambers are suitable for large particles of 50
to 1000 microns; the collection rates are  40 to 60% and the  in-
stallation  and operation costs  are minimal. For medium size
particles  of  5  to 100 microns,  cyclones  show 85 to 95% effi-
ciency and the cost is medium. For particles of sizes 0.1 to 100
micron, sound wave collectors  yield a slightly better collection
rate (80-95%) than venturi scrubbers and the cost of operation
is also more advantageous. Bag filters  collect  90 to 99%  of
0.05 to 20 micron particles and both installation  and operation
costs are medium; 0.05 to 20 micron particles may be collected
80 to 99% by an  electrostatic  precipitator, which is costly to
install, but the operational  cost runs from minimum to medi-
um.

THEIR REACTIONS.  (Juyu suisoka  datsuryu-ho no shokubai

the Dicussion on  Desulfurization Techniques, 4th, Yokkaichi,
Japan, Oct. 20, 1971.)
Difficulties in desulfurization are mainly found in the  direct
method, due to the difficulty of precipitation of  vanadium and
nickel  between and within the catalyst  particles,  and the
lowering  of catalyst activity caused by asphaltene. Thy princi-
ples of desulfurization systems are explained with illustrations
and operating variables of various types of systems; catalysts
are reviewed. In the direct  method of desulfurization, using a
stabilized  bed of  cobalt molybdenum alumina (CoMo/A1203),
the desulfurization rate drops  drastically in the beginning; it
continues to drop  up to 50 hours, then stabilizes. Higher desul-
furization rates are obtained with higher reaction pressures, or
using one mm diameter spherical catalyst particles rather than
two mm  diameter particles, or thicker catalyst layers under a
given condition.  The ratio  of  desulfurization in one  kind  of
heavy oil  from the Middle East by the direct method showed
elimination of 64% of vanadium, 68% of  sulfur, 46% of nickel,
and 49% asphaltene. The life and catalytic reaction of catalysts
depends  on types of  oil for  which  they are  used; but  in
general, efficiency can  be improved by enlarging average pore
sizes, improving the pore diameter distribution  in relation to
the macropore volumes, and increasing the surface area in
relation to the volume of a catalyst.

The  process  removes acid  components like  carbon dioxide,
hydrogen sulfide, hydrocyanic acid, sulfur dioxide from waste
gases.  The gases are absorbed with aqueous solutions of or-
ganic  compounds  and  removed  from  the  washing liquid
through  distillation.  The organic compounds in the washing
liquid  are derivatives of gamma-piperidon  which contain  an
unchanged amino-and-keto-group  like  2,2,6,6-tetramethyl-4-
oxo-piperidine.  In these  compounds,  the  keto-group  is in a
para position to the amino-group. These compounds absorb in-
organic acid  compounds by forming loose bonds with  them
which  are easily broken by reduced pressure, by an increase in
temperature,  or preferably  by both simultaneously.  Thus a
separation of the absorbed  acids is achieved without decom-
position or condensation reactions of the gamma-piperidon in a
solution which  is returned to the  process. Distillation is per-
formed in a column at 60-80 C while scrubbing takes place at
20-30 C.

ACTION OF THE FRENCH MINING INDUSTRY.   (Action
des Charbonnages de France). Text in French. Pollut. AUnos.
(Paris), 23:22-26, Oct. 1971.
The French  mining  industry has participated  in  the  fight
against pollution in the mines themselves, in the processing of
coal, and in its combustion. The necessary sampling and mea-
suring  devices  were developed  by the Centre  d Etudes et
Recherches  des Charbonnages de France. In the mines, dust
formation is controlled by the infusion of water under pressure
into coal seams. During mining itself, water is sprinkled under
pressure on coal banks that are being mined.  Modern continu-
ous  methane monitoring equipment with alarm devices is also
used. A difficult problem was coke oven pollution control in-
volving  dust and  a tar aerosol.  But  the  new oven charging
techniques used in  the  Lorraine basin  almost  completely
eliminated emissions. The  French mining industry is charac-
terized by a  shortage of anthracite which alone burns without
emitting coal tar. Therefore, smokeless coal is being produced
by distillation or by oxidation on a large scale. The anthracite
method alone yields 1,200,000 tons of smokeless coal a year.
                         Smokeless  coal  has   thus  replaced  the   traditional  coal
                         briquettes which generated coal tar. Basic research currently
                         being  pursued bears on the  formation of nitrogen oxides  in
                         furnaces, on the optimal physical and chemical conditions  in
                         waste incineration, on solids-gas interaction in  combustion
                         gases, and  on the harmfulness of particulates and gases  to
                         human lungs.

                         bons,  and other elements in  the material oil which impair the
                         efficiency   of  desulfurization,  various  other  operational
                         problems,  types  of  reaction  towers,  wear and  corrosion
                         problems, and economics are discussed. The elements which
                         cause problems of desulfurization are vanadium, nickel, and
                         close to 30 other metals of smaller amount. Ninety per cent  of
                         these  metal compounds are concentrated in  the oil residue  to
                         be desulfurized. These metals are extracted by catalysts which
                         cannot be  recovered  once  used. Asphaltene,  an aromatic
                         hydrocarbon and insoluble to propane and  pentane, contains
                         much more sulfur, nitrogen,  and metal compared to solubles
                         and presents a great problem. The amount of sulfur contained
                         in asphaltene is approximately twice as much as the amount in
                         raw oil. Asphaltene is not only difficult to desulfurize, but also
                         impairs the catalytic action  of other elements once it is ad-
                         sorbed by the catalyst. According to the 1970 report  of the
                         General Energy Investigation Committee, the average sulfur
                         content in the total fuel consumption in 1974 will be  0.95%,
                         and in 1978, 0.55%. The sulfur content in the oil  desulfurized
                         by the indirect method presently under operation is 0.3 - 0.5%,
                         and that of the oil desulfurized by the direct method is approx-
                         imately 1.0%.

                         By the end of 1970, 11  indirect desulfurization systems with a
                         total capacity  of 256,000 bbl/d were operating, and they are
                         expected to increase to 15  systems, producing 39,500 bbl/d.
                         Japanese oil import consists  of 41% Iranian oil containing 2.5
                         to 2.6% sulfur in the heavy oil form, which can be reduced  to
                         1.5 to 1.6% by an indirect desulfurization process. This com-
                         pares with the Khafji oil,   eight  percent of the  oil  import,
                         which contains 4.1% sulfur in heavy oil which can be reduced
                         to 2.6% content. Three direct desulfurization systems presently
                         operate  in  Japan,  treating 112,760 bbl/d oil,: and two more
                         systems will be added in the next two years, increasing the
                         capacity to 156,000 bbl/d. Of the stabilized bed operation and
                         fluidized catalyst bed processing, the latter is more complex in
                         mechanism, but the exchange of  catalyst is possible  without
                         stopping the operation of the entire system. Also,  maintenance
                         of catalytic activity is  easier, making a  continuous operation
                         for an extended time possible. It also desulfurizes residual oil
                         with many metallic components which  decreases the activity
                         of catalysts and of decompressed distillation residual oil. Since
                         this process is regarded most suitable for Japan which has  to
                         depend on  various types of  raw oil, The Ministry of Interna-

The  effects of automotive exhaust emissions  on air pollution
are reviewed with respect to maximum allowable  concentra-
tions, environmental emission standards,  regulation of  engine
exhausts, and various control methods. Automobiles emit car-
bon  dioxide, carbon monoxide, hydrocarbons, soot and lead
participates, aldehydes,  and odors as combustion gas from ex-
haust pipes, crankcase blowby gas, and fuel tank or carburetor
vapors. Control methods included engine design modifications,
improvements of the air inlet and ignition systems,  air-fuel
ratio, exhaust,  air injection and fuel injection  systems, and
prevention  of evaporation loss.

In a  fluidized bed combustion incinerator,  a  layer of  heated
and constantly moving particles such as sand acts as a com-
bustion medium,  and makes complete burning possible at the
low temperature of 700 C.  The solid waste comes in contact
with  the  heated sand  and  organic  material is completely
decomposed and oxidized. The combustion gas goes through a
heat  exchanger before emission from the stack. Soot is further
collected by either a multi-cyclone, a filter,  or a wet-type dust
collector.  The  smoke  is made  completely odorless  by the
complete combustion. Flow  sheets and the  design and  opera-
tional specifications are  presented.

CAUSE AND CONTROL OF ODOR IN AIR  CONDITIONED
SPACES.  Air Cond., Heat., Ventil., vol. 56:77-81, Sept. 1959.
Obnoxious odors in enclosed spaces  include tobacco  smoke
odors, chemical and product odors, odors introduced from the
outside atmosphere, and odors from air conditioning coils. To
keep odor  perception and irritation at a minimum, air  condi-
tioning spaces should be designed for about  50-55% relative
humidity. Temperature  can generally be  ignored since it has
slight effect on odor level at constant specific humidity. Ven-
tilation and charcoal adsorption are effectively and extensively
used in air  conditioning for odor removal by engineers. In ven-
tilation, air containing  objectionable gaseous  odors, irritants,
particulates that obscure vision, and toxic matter are replaced
by clean  fresh outside air. Ventilation requirements for human
occupancy  are a function of space person and the activity. An
Activity Curve is given for  determining the requirements for
various conditions. At air temperatures below 125 deg,  odors,
vapors, and gases (except carbon monoxide  or carbon dioxide)
are  effectively  removed  by charcoal  adsportion. Carbon
requirements can also be determined from the Activity Curve.
Exhaust gases between 125-500 deg can be destroyed by cata-
lytic combustion at  500 deg.  For higher temperature gases,
direct combustion at 1200  deg is employed. Tests were made
on odor adsorption and release in  an enclosed space. Methods
for measuring odor intensities were discussed.

lubricant distillates, to absorb sulfur dioxide  was experimen-
tally confirmed.  Determinations of combined sulfur and free
SO2 contents  of the absorbents  showed that the petroleum
products absorb SO2 as a  result of chemical reaction between
SO2 and hydrocarbon compounds. The liquid  distillates had a
greater absorbing capacity (96.1%) than the other petroleum
products.  The new absorbents are included in a. classification
of methods of absorbing SO2 from waste gas.

Measures  for reducing exhaust emissions from internal com-
bustion engines are discussed  with special reference to nitric
oxide.  A substantial reduction in NO appears possible by com-
bining  exhaust gas recycling with a high-temperature exhaust
reactor for the oxidation of hydrocarbons and carbon monox-
ide. A two-stage catalytic  muffler also promises to purify ex-
haust gas  without adversely affecting engine performance. The
NO is  reduced by a catalyst in the first stage, after  which air
is admitted and the hydrocarbons  and CO are  oxidized. It will
be difficult to lower NO levels below one gram/mile in engines
other than gasoline engines. In Sterling engines, far-reaching
recycling  is required, and  even in steam engines  combustion
gas temperature must be 1000 C or below. Electric engines are
exhaust-free but the lead used  in present batteries may  exceed
the amount in gasoline additives. If it is necessary to limit NO
to less than five grams of nitrogen  dioxide/one kilogram  of
fuel, the same standards should be applied to boilers  and other
combustion devices.

New formulas are given for the calculation of the radioactive
degree of removal; with these, the measurement of crude and
pure air in the experimental procedure  can be avoided.  Au-
toradiographs of different filter materials give information con-
cerning the structure and composition of  the filters. Autoradio-
graphs of thermal-precipitator samples were taken from a mix-
ture of the thorium emanation. They show that the thermal
precipitator removes 100% of the radioactively tagged particles
of suspended matter, that the precipitation begins in  front of
the heated filament, and by comparison with microscopic ex-
aminations  in  the  bright and dark  field,  that the maximum

The current status of accumulators and  fuel cells for electric
vehicles is  reviewed. Most accumulators  under development
are unsuitable because they contain expensive materials whose
quantities are limited. Except for the heavy lead accumulator,
there remain only the air-zinc accumulator  and the sodium sul-
fide accumulator. Several years of testing  have resulted in no
practical application of the latter.  Although their primary cells
have been manufactured for decades, two essential problems
exist with  air-zinc accumulators: development of a suitable
electrode for air intake and the dissolution of the zinc elec-
trode during discharging. It is doubtful that the air-zinc accu-
mulator will replace the lead accumulator on electric trucks.
Work on mechanically rechargeable fuel cells is still in the ini-
tial stage.

The surfacing of asphalt roads requires a mixture produced
from a mineral aggregate and a bituminous  binder. The mineral
aggregate may be  natural rock  material (sand  or gravel),
crushed rock (rock fines, grit, road metal), crushed blast fur-
nace slags,  or rock dust (as  filler).  In order  to obtain the
desired  grain-size composition,  the  mineral  aggregates are
mixed in a certain proportion, for which standards and codes
of practice exist. Plant operation includes batching of the input
aggregates, drying and heating, mixing, haulage and loading,
storage, preheating of  rock  dust, and treatment  of binder.
Sources of dust formation are indicated, as well as the type of
dust  formed  and means  of  reducing dust  concentrations.
Mechanical collectors, wet collectors, filters, and electrostatic
precipitators are evaluated for this application. The release and
prevention of gases, vapors, and odors are  also discussed.

                        Fine-dispersion atomization  of  the liquid is one of the most

                        between a  liquid and gas.  The  intensity  of the  absorption
                        process with fine atomization can be increased by using rotat-
                        ing perforated cans, particularly with outflow openings of rela-

                        Advancing the intake valve opening or the exhaust valve clos-
                        ing time significantly reduced hydrocarbon and nitrogen oxide

                        45 deg btdc reduced hydrocarbon emissions by 25%  and nitric
                        oxide  emissions  by  38%. Hydrocarbon emission decreased
                        25% when the exhaust valve closing was advanced  to 22 deg
                        btdc. Delaying the closing to 65 deg btdc resulted in an 18%
                        decrease in  hydrocarbons. Nitric  oxide emissions decreased
                        45% at the maximum exhaust valve closing advance and 50%
                        at the  full exhaust valve closing retard.  The valve  timing
                        changes appeared to reduce  nitrogen oxide emissions  by  in-
                        creasing internal  recirculation. Increases in internal recircula-

                        tional  power plants as far as desulfurization of wast gases is
                         concerned. In conventional power plants, desulfurization of
                        flue gases prior to discharge into the atmosphere is feasible

only at great expense. Simpler solutions are available for the
two new methods. In the fluid-bed method, ground limestone
is added  to the fluid bed. The sulfur  is bound in the fluid bed
and the loaded additive is  discharged with the ash.  It is ex-
pected that a  degree  of desulfurization of  up  to 90% can be
achieved with this method. In coal-pressu e- gasification, the
hydrogen sulfide can  be removed from the gas prior to com-
bustion.  Laboratory experiments have  shown that  the  hot-
potash-method  is very suitable  for  this purpose. The pres-
surized gas  is  passed through a  cooler-saturizer  system.
Preliminary scrubbing of the  gas is carried out in the cooler,
the actual desulfurization then takes place in the absorber con-
taining a potash solution.  In  the saturizer, the gas is  heated
again  countercurrently to ISO C. Elemental sulfur is produced
from the absorbed gas in a Claus furnace. A degree of desul-
furization of 90% is feasible.  An experimental  plant for desul-
furization of 3500 cu  m/hr  will  be erected in the power plant
Kellermann. The waste gases from the combined desulfuriza-
tion/pressure gasification process are  entirely dust free.

HOLLOW HIGH-SPEED SCRUBBER.  Soviet  J. Non-Ferrous

10(9):61-63, Sept. 1969. 3 refs.
A pilot gas purifier consisting of an electric  separator and a
hollow scrubber with spray nozzles was tested  for its ability to
remove gaseous and  solid  fluoride compounds from  exhaust
gases at an aluminum plant. The efficiency of  gas purification
in the scrubber was determined  at gas linear velocities of 3-7
m/sec, gas  inlet temperatures of 40-50 C,  and  spraying densi-
ties of 20 and  30 cu m/sq m/hr. Spray density had a greater in-
fluence on the  degree of hydrogen fluoride entrainment than a
change in gas  velocity. The  degree  of purification remained
constant  within the gas-velocity range  tested, but increased
with an increase in spraying density.  An equation is given that
predicts the performance of  the hollow, high-speed scrubber
under various operating conditions.

POWER  STATION CHIMNEYS. Thermal Eng. (English trans-

1971.  4 refs.
Corrosion problems associated  with  four  types  of single-flue
chimneys installed at large Soviet thermal  power stations are
discussed. The chimney types are reinforced concrete  with
ceramic linings (I); metal chimneys  made  of  individual ther-
mally  insulated sheet-steel  cylinders  (II);  reinforced concrete
with metal flues  for  thermal insulation (III);  and reinforced
concrete with ventilated  clearance between the flue and the
lining (IV). The best  results were obtained with type IV pro-
vided the ventilation was forced and a static pressure existed
in the clearance. Under these conditions, there is no gas flow
toward the supporting  reinforced concrete shaft and thus no
corrosion  of  the  later.  However,  the  requirement of  a
minimum of  two fans  with  electrical drives  and a  reserve
power supply make type IV chimneys with forced ventilation
more expensive.  As a solution, a new type  of  reinforced
concrete chimney is proposed,  one  that is  pressurized in a
naturally ventilated  clearance of variable width between the
reinforced concrete  shaft and an acid-resistant lining. The new
design should increase  the reliability of chimneys for high-
capacity thermal power plants.

Each stage of a multi-stage turbulent spray tower consists of a
perforated plate above  which is the turbulent layer. The holes
in the perforated plate  are so  small that the fluid may pass
through but the solid particles may not. Fluid and particles
pass countercurrently through the tower.  On each stage solids
and fluid are mixed  intensely and separated again. For calcula-
tion of the multi-stage spray tower the pressure loss, the parti-
cle concentration on each stage, the average residence time,
the  residence  time  distribution, and  the particle throughput
must be known. The  mathematical  determination of  each
parameter is discussed. Of all contributions to the total pres-
sure, only the pressure  loss of the fluid at the transit through
the turbulent particle mass and the  pressure loss  across the
perforated plates  is  of  significance. Analytical expressions for
the two quantities are  given, as well as the other parameters
mentioned above. A Fortran program has been written for the
calculation of the fluid dynamic properties of multi-stage spray
towers together with detailed instructions for feeding the pro-
gram into a computer.

The installation of  electric separators at high-output  cement
mills is recommended as an economical  approach  to keeping
dust  emissions  within  the   limits   permitted  by  law.  A
prerequisite for stable and effective operation of filters is the
installation of a water spray nozzle in the third chamber of the
mill. The construction and operation of the nozzle and results
obtained with such a nozzle are illustrated by an example. The
results justify the recommendation.

Results  of  experiments  concerned with  washout of fission
fragments by atmospheric precipitation  in the subcloud layer
of the troposphere are presented. Rain water was collected in
sampling tanks at three  different elevations on a mountain
slope. The rainwater was evaporated and the beta-radioactivity
of the residue  was measured. Fallout  density increased as the
sampling point was lowered, indicating  that fission fragments
are washed out by the precipitation. The amount of increased
radiation showed considerable variation.

METHODS OF MEASURING AIR POLLUTION (PART 6).
Metodi  di Misura dell' inquinamento Atmosferico (Sesta Parte.
Fumi Polveri (Milan) l(7):18-24, Jan. 1967. It.
Two methods  for measuring minute  quantities of fluorine in
the atmosphere are described.  1) Two methods are given for
measuring a  sample with  an  impinger.  In  the  photometric
method air is introduced  in the appratus containing a normal-
ized solution of 0.1 N NaOH which absorbs the  fluorine ions.
The ions are then separated in the vapor state and the amount
of fluorine determined photometrically.  The sensitivity of this
method is 3 micrograms F/cu m of air when measured directly,
and 0.6 microgram F/cu m when preliminary concentration
measurements are made. The metric titration method, less sen-
sitive than the photometric (10 micrograms F/cu m, is used for
high fluorine  concentrations. Equations  are given  for both
photometric and titration methods from which the concentra-
tion of fluorine can be calculated. 2) In  micro-diffusion
methods, air is  passed  across a bottle  containing gas and
pieces of plexiglass on which compounds containing fluorine
are  absorbed  in 0.1  N  NaOH.  Extraneous  substances are
eliminated by  micro-diffusion and the  amount of fluorine  is
determined photometrically.

Important papers published in Japan Analyst in 1964 and 1965
are  summarized.  The  subject is limited  to  measurement
methods of  air pollutants known to be  toxic to  health. Pollu-
tants from  stacks and automobile exhausts  are  covered, in-
cluding many cyclic hydrocarbons, aldehydes, sulfur oxides,
nitrogen  oxides, ozone, carbon  monoxide,  carbon dioxide,
fluorine compounds, hydrogen sulfide, lead  compounds, and
offensive odors. Various  sampling  methods are  described,
especially using filtering with  glass wool filters,  electric dust
collectors, gas absorbers, and portable samplers containing sil-
ica gel. The pollutants can be measured by electroconductivity
methods, colorimetric  measurement  recorder, gas  chromato-
graphic analysis, electron capturing detector, and hydrogen ion
detector. The papers summarized  do not include those dealing
with industrial or occupational environment or mining.

A survey of  air pollution measurements is presented. In the
group of emission measurements,  a block diagram for continu-
ous CO2 and SO2 measurements  is given and some details of
sampling and filtering are discussed. A nomograph  relates the
SO2 emission with  the sulfur concentration of the fuel. These
measurements operate on the principle of infrared absorption.
Another block diagram shows examples of dust measurements.
Both the electrostatically  operating 'Konitest'  and a meter
based on light  extinction are employed. An electrochemical
device determining  chlorine is explained. Here the chlorine ox-
idizes iodide  which in turn causes a depolarization  current to
flow. As an example of concentration measurements, an elec-
trochemical device  determining H2S in concentrations  as low
as 1 ppb is given. The electric current arising as  the result of
the formation of silver sulfide is of the order of 0.1 micron
amp which can  be  amplified and recorded. A short  discussion
of practical aspects of sampling and statistical evaluations of
results,  in particular, relations to wind directions,  concludes
this paper.

Japan Petrol.  Inst. (Tokyo), 9(3):214-216, Mar. 1966.10 refs.
The methods  investigated are  the  electrical  conductivity
method,  rosaniline  method, and Saltzman method. Drawbacks
to the electrical conductivity  method are that SO2 and SOS
cannot be measured separately and that H2S, mercaptans, and
other elements  interfere with measurement. In addition, the
electrical conductivity of the absorbing liquid depends on the
temperature. The rosaniline method is used only for SO2. Con-
siderations  in using this method  consist of  the speed of ab-
sorption  of the  air tested,  the shape of the absorber, absorp-
tion efficiency, and  maintenance of the absorption  liquid.
Impingers and air  washing bottles are also required. The ab-
sorption  of test air depends on the celocity and on the shape
of the bottle; absorption efficiency of the  absorption  liquid

was  good,  indicating the need for only  one absorption tube.
Data  obtained  by sue  of both  electrical  conductivity and
rosaniline methods were  in good  agreement with each other.
As for the  Saltzman method for N-oxides, the absorption effi-
ciency was found to depend on the speed of absorption and on
the type of absorption tube used. It is difficult to make a per-
fect  collection of NO2 by the Saltzman method. The hourly
variation of NO2 concentration in Yokohama is graphed; it
reached a peak of 0.05 ppm between 9 and 10 A.M. which is
much less than the corresponding SO2 concentration.

The  detector described consists of two parts: the  measuring
section and the recording part. The efficiency of the measuring
part  was determined by a potentiometer which measured the
relation between the iodine concentration and electric potential
which are proportional. There was difficulty in obtaining good
repeatability values; the problem  is discussed in  some detail.
The efficiency of the automatic recording equipment was then
tested. A wiring diagram of  the  apparatus  is included. The
relation between resistance change in the wire and deflection
of the recorder is graphed. As for  operating procedure, the ef-
fects  of potential stability, bubbling, and ultraviolet rays were
investigated. Graphs  illustrate that initial potential stability in
potassium iodide is difficult to reach but once obtained, the
stability  will remai^  constant during changes in  potassium
iodide. Other effects noted were that bubbling affects the volt-
age and the effect of ultraviolet rays is great. The detector was
used for NO2, ozone, radioactive  iodine, and other  gases. The
process and methods of examination are described in detail.

The  determination of sulfur  oxides  and nitrogen  oxides in
smoke and in  air  are covered. SO2 in smoke  is measured
colorimetrically  or  by  detection tube. Two methods  are
described: one  for measuring pollutants after the combustion
of coal or heavy oil or  for gases mixed with NO2  and the
other for mixtures of SO2 and SOS. Procedures are given for
making the test liquid (absorption liquid) and for exact mea-
surement for each method. The detection tube is  illustrated
briefly. The absorption tube method is not sufficient for NO2
detection. A method  of  almost perfect collecting  efficiency
which is  used  in  the Kanagawa Prefecture  Public  Health
Laboratories is described. The absorber is composed of a mix-
ture  of NaOH and butanol. For SO2 and SOS measurement,
the  electric  conductivity  method   and barium   molybdate
method are illustrated. The rosanaline method is used as well
as an alkali filter paper method. The latter is superior to the
widely used PbO2 method in that  reagent quality  does not af-
fect the measured value and the collecting efficiency does not
depend on temperature and humidity.

The  East-North Power Station together with the Central Elec-
tric Power Institution  studies a simpler method to standardize
dust and soot-measuring methods. They tried to find the point
which gives  the average amount of soot and dust without mea-
suring the distribution of concentration. They also investigated
the possibility of measuring the  amount of soot  and dust in
grams/cubic meter using  a soot and smoke  meter of  the
photoelectric type.  In this experiment, the temperature dis-
tribution, velocity  distribution, and soot and dust concentra-
tion  at the  cross-section of the  smoke duct were measured.
Measurements were also made at the inlet and outlet of  the
dust collection device. For measuring concentration, at the in-
let, the constant-velocity suction tube  method was used, a dust
tube alone was used when heavy oil  was  the fuel, and at  the
outlet, both  tubes were used. When coal was used as fuel,  the
size  of the dust particles was 30 to 40 microns at the  inlet and
5 to  7 microns at the outlet. It was found that the curves of
the velocity of the gas and of the soot and dust concentration
were almost the same indicating that the average amount of
soot and  dust could be measured at the point where  the
velocity of the gas was average. Measurement of  the distribu-
tion  of soot  and dust is only required  for determining  dust col-
lecting efficiency.

A method  for the determination of dust content in air  by
weight is described. The  method utilizes fabric filters  and ena-
bles  one to  determine the dynamics of dust formation during
various  industrial processes in short  periods of time, and to
evaluate  the effectiveness of  dust-prevention measures.  Long
experience  in  the  use of AAF-W filters in the laborator,  as
well  as in mines and various industrial enterprises brought  out
the following advantages over other filtering materials: 1) high
efficiency of dust retention in the linear filtration rates  of up
to 100-150 cm/sec; 2) the flow of air passing through the filter
can be brought up to 100 liters/rain.; 3) the low aerodynamic
resistance makes it possible to increase the rate of sample tak-
ing,  and in this way decrease the sampling time; 4) as a rule,
the filters are  weighed without preliminary drying; 5)  the low
weight of the filter (25-30 mg) makes it possible to determine
the minimum weight of dust of 1  mg; 6) reduction of the time
required  for the entire analysis  makes it possible to obtain
results of the determination of the  dust content of air practi-
cally on the  same day on which the samples were taken. In-ac-
tual  practice AAF-W-10 and  AAF-W-18 filters are used  for
determining  the dust content by  weight. Here the code letter
W signifies weight  and 10 the diameter of  the working surface
of the filter in sq  cm. The principle  of determination of  the

amount of dust expressed in mg/cu meter, using FPP-1S cloth
filters consists of drawing a specific volume of dust-laden air
through the filters with subsequent determination of the gain
in weight and calculation of the dust concentration in units of
weight per unit of volume of air.

The  ultramicroscopic method  for the determination of  the
number of dust particles contained in one unit of volume  of air
is described.  In ultramicroscopy the  dust particles  are  seen
against a dark background in the form of luminous points. The
method makes it possible to determine  dust particles of micro-
scopic and submicroscopic (to 0.04 micron) - ultramicroscopic
size. The  investigation of  the  dust  content of air by this
method can be performed either under industrial or laboratory
conditions. This method enables one to determine rapidly (in
5-10 minutes) the concentration of particles in a moving stream
of the investigated air, and  in the investigation, the dispersed
phase is not separated from  the dispersion medium, there is no
phase is not separated from  the dispersion medium, there is no
conglomeration  and,  conversely, no breaking up of the dust
particles or changing  of their number. The instruments used in
ultramicroscopy  of aerosols are divided into two types:  I) in-
struments  with  which the particle count is performed in iso-
lated volumes of an arrested air flow, and 2) instruments with
which the particle count is  performed  in a continuously mov-
ing air flow. The disadvantage of  all these instruments lies in
the possibility  of  settling  of particles on  the  walls of  the
rubber tubes, and in the instruments  of the first type also in
the chamber (cell), in which the particles are  counted. The
main parts of the instruments are the cell, the light source, and
the microscope. The individual  design features  of the instru-
ments pertain to the arrangement of the lighting and optical
systems. The use of this apparatus for  dust content determina-
tion by the counting  method either under laboratory  or indus-
trial conditions  (in  plants,   shafts, or mines) proved that it
yields good results. A wider use of this method in the practice
of hygienic investigations is  recommended.

Comparative tests of gravimetric and counting apparatuses for
the determination of  the dust content of air are discussed. The
procedure with the use of  AAF-W-10 filters is  recommended
instead of GOST-50, as the  most progressive and reliable one;
                        the equipment for the gravimetric determination of the dust
                        content of air is recommended for adoption in research work.
                        The gravimetric method must be retained in the future as the
                        basic one, and at the same time work must be continued on its
                        further improvement, in particular, its automation. 3) Along
                        with the gravimetric method, in the practice of the work of in-
                        stitutes it is expedient to use in a parallel a counting method.
                        Among the  counting apparatuses, the most reliable data are
                        given by VDK-4 apparatus,  which however, must be further
                        improved. The field aerosol  counter for the determination of
                        the concentration by count in the flow is recommended for use
                        in the practice of hygiene research. The use of instruments for
                        the determination of the concentration by count in arrested
                        flow is not recommended. It  is necessary to continue the work
                        on the improvement of the counting methods for determining
                        the dust content in air, along the line of automation of the par-
                        ticle count of dust and determination of its size distribution.

                        A fabric filter method was compared with the Czechoslovaki-
                        an membrane filter method.  Comparison was made under the
                        conditions of the mining industry during the hygienic evalua-
                        tion of drilling of rising blast holes in soft rock. All the opera-
                        tions  were performed under  the same  conditions, at the same
                        work locations,  and with practically  unchanged ventilation.
                        The statistical processing of the  results established that the
                        difference in the mean  dust concentrations is not authentic,
                        i.e. both filters produced the same results. Both methods  can
                        be assumed to be of equal value, which fact enables  one to
                        compare the results of investigations performed in the USSR,
                        Czechoslovakia, and other countries which use these methods.
                        It must be noted that FPP fabric filters  have certain  ad-
                        vantages, because they have  less resistance  and,  moreover
                        they  do not require drying to  constant weight owing to their
                        hydrophobic nature. At the same time one  must note  the
                        distinctive feature of the Czechoslovakian apparatus, which
                        has special deivies for assuring the constant rate of air-sample
                        taking.  This apparatus  can  be successfully used with  FPP
                        fabric filters.

particle size distribution of dust is composed of the following
operations: preparing the  mount, calibrating the  micrometer,
measuring and counting the dust particles of specific fractions,
and  calculation  of the particle  size distribution.  The  dust
specimen mounts are usually prepared directly  at the produc-
tion  site, at the  sample-taking location, i. e. in the breathing
zone of the workers, as well as next to the dust  producing
spot, near the ventilation devices, in the air ducts, at the ven-
tilation air  exhausts, depending on the aims and  tasks of the
investigation. The basic disadvantages of the method of study-
ing the particle size distribution by means of a micrsocope are
connected  primarily  with the possibility of  not  obtaining
satisfactory dust mounts,  with not accurate  calibration of the
sizes of eye-piece micrometers, and finally, with the sensitivi-
ty and the  susceptibility to fatigue of the eye in microscopic
work, along with the exceptionally large amount of work in-
volved. The main, most important disadvantage  of the method
in principle, is the feasibility to determine with its  aid of the
particle size distribution only according to the number of parti-
cles, whereas for the hygienic estimate it is important to know
the mass of the dust of various particle size.

An apparatus  was developed in order to  be  able to  use dilute
suspensions and take small specimens of dust. As a balance a
sensitive quartz spiral stretching 3  to  6 mm/mg was used.
Components  of  the apparatus  are: thermostat, consisting of
stirrer, contact and control thermometer and electronic relay.
The thermostat container is made of plexiglass.  The apparatus
was  tested  in the laboratory  with  a number of  powdered
materials (quartz, coal dust, granite dust, etc.) In the analysis
of the  sedimentation curves obtained the  analytical calculation

The  method  of  determination of free silicon dioxide in the
presence of silicates is based on the fact that pyrophosphoric
acid  dissolves the silicates  and has practically no  effect on
quartz. The quartz content  in the undissolved  dust is deter-
mined  by  the  gravimetric  method  after  treating  it  with
hydrofluoric acid in the presence of sulfuric acid,  or by the
colorimetric method with the reduced silicomolybdate com-
plex. The senditivity of the method  is 2 micrograms  SiO2 in
the analyzed volume of the solution. Under the above condi-
tions phosphorus, arsenic, and iron do not inter- fere. Another
method is  based on  the  selective  destruction of free  SiO2
through fusing it with a special 'composite' flux, extraction
from  the  cake of the  alkaline  metal  silicate obtained, and
colorimetric determination  of  it according  to its yellow sili-
comolybdate complex. Reagents, equipment  and calculations
are included.

Etching minerals of various composition with acid forms on
their  surface an amorphous corrosion  film, which is stained
with  methylene  blue  into different colors, depending on its
chemical composition. The method  can be  used not  only for
determining various minerals,  but also  for the  study of  the
quantitative composition of rocks  after they are ground to
powder. For this purpose the rock is  crushed in a cast-iron
mortar and  its powder is screened through  250 and 325  mesh
sieves. The  analysis is performed on the plus 325 mesh frac-
tion,  which was established experimentally as approximately
corresponding to  the  mean  composition  of  the  rock  in-
vestigated. For the analysis 0.5-1.0  g of powder is taken and
placed in  a  porcelain  dish  and  covered  with  5  percent
hydrofluoric acid. During the five-minute etching the material
is stirred several times. After etching, the acid is decanted off
and the powder, without being rinsed with water, is covered
with a 0.025 percent  solution  of methylene blue basic). The
staining continues 5-7 minutes with constant stirring of  the
suspension.  Upon the elapsing of the above period the dye is
poured off, the  powder is rinsed with water (1-2 times) and
dried  in the same dish. The  stained powder mount is then
prepared and viewed under the microscope  with regular or
polarized light.

Chem. (Berlin), 230(5):344-347, Aug.  1967. 4 refs.
A procedure is proposed for the determination of low concen-
trations of ammonia in air by the  indophenol reaction with
sodium phenolate and sodium hypochlorite. The limit of detec-
tion (1 micro g NH3 at 99% confidence limit) and the precision
(standard deviation plus or minus 2 to  4%) are  equal to  the
Nessler reaction. However, with the  present procedure there is
no interference  by moderate  amounts  of  hydrogen sulfide;
therefore prior isolation of the ammonia by steam distillation
usually can be omitted. Hydrogen  sulfide under 60  micro g
does not interfere with the determination of 5- 50 micro g of
ammonia.  If larger amounts of hydrogen sulfide are present,
the acidic  solution is boiled for five minutes until the odor of
hydrogen sulfide disappears. Nitrite  and sulfite up to  1 mg do
not interfere. The presence of formaldehyde does interfere and
requires distillative purification of the ammonia solution.

The analysis of aerosol particles of individual compounds is of
considerable interest for  air pollution  studies. Aqueous solu-
tions of ammonium nitrate were atomized in a chamber and
the aerosol  was  passed  through  a  membrane ultrafilter at a
rate of 7  1 ./min. The filter was then placed in a solution of 4%
nitron in  10% acetic acid for 20 minutes. The spots which con-
stitute  a  reaction product of NO3  with  nitron were counted
under a microscope. The NH4  particles were determined in a
similar manner but with Nessler reagent.  The spots  did  not
fade after 6  months and the method  was found  to give
reproducible  results. Particle size  distribution may  also be
determined.

German.  Z. Instrumentenk. (Brunswick), 85(6):188-190, 1968.
The three principles used for measuring  both the emission of
gaseous pollutants from a source and their 'immission' are: (1)
physical methods; (2) physical methods with the aid of chemi-
cal reactions; and (3) electrochemical methods. As a purely
physical  measuring method  the photometric principle is em-
ployed in the  ultraviolet, visible or infrared wavelengths. The
disadvantage of  this method is lack  of sensitivity and it is
therefore  employed mainly for emission measurements,  which
are a thousand to ten thousand times larger than  immission
measurements. The second method, which depends first on a
chemical color reaction with sub- sequent measurements with
a  photometer, is more  sensitive. It will measure  pollutants
from  1 ppm down to 0.02 ppm. lonization detectors with or
without the  aid of chemical reactions  are also employed to a
limited extent. Several photometers and ionization detectors
are described  and illustrated. The electrochemical methods are
the  most sensitive  and  selective. Numerous  methods  are
available, but so far  only  the  conductivity and galvanic
methods have been employed for immission measurements.
Several analyzers are described and illustrated. The preferred
automatic method of analysis with a range  of  the  smallest
measurable  con-  centrations for the most important  air con-
tamination gases is tabulated.

(Bestamning av  luktande luftfororeningar.) Text in Swedish.
Nord Hyg. Tidskr. (Copenhagen), 47(2):41-71, 1966. 91  refs.
Psychometric  methods  for the sujective  determination of
odorous  air pollutants are surveyed, with a discussion  of the
physiological and psychological bases of smell. Since odors are
a  a  problem of emvironmental hygiene, they are  studied at
present by the determination of an odor threshold in a  series
of diluted air samples. Some of the problems involved in such
determination of an odor threshold in a series of diluted air
samples. Some of the problems involved  in such determina-
tions  are   mentioned:   individual   variation,   adaptation,
background  variables,  climate  etc.  Psychometric methods
used, such as  stimulus presintation and indicator response, and
                        the pricciples of extrapolationg supralim- inal intensities, are
                        discussed,  as  well  as the different  types  of  olfactometers.
                        Odor thresholds found in the literature are rarely similar, due
                        to  the  inaccuracy  of the  physical and chemical analytic
                        methods used  and to the  varying  statistical  and  sampling
                        techniques employed. Different odors may also interact so that
                        the threshold to the combined smells  may not be merely addi-
                        tive. Annoyance from odors is best studied by epidemiological
                        methods where the exposure dose is known.

                        When NO2 is introduced into an acetate solution of  sulfanilic
                        acid and N-(l-naphthyl)ethylenediamine dihydrochloride, a red

                        determination of small quantities of NO2. The process can be
                        calibrated either by means of defined NO2-air mixtures, or by
                        the use of sodium nitrite solutions, which are easier to handle

 METHODICAL STUDIES  ON THE  DETERMINATION OF
 LOW CONCENTRATIONS OF NITROGEN  OXIDES IN THE

 Text in Polish. Med. Pracy (Lodz), 17(3):218- 222, 1966. 3 refs.

 The Griess-Illosway method is most often used to determine
 low concentrations  of nitrogen oxides in the air and is known
 to detect microgram NO2 in 16 ml. of solution. To determine
 values within th range of the maximum permissible concentra-
 tion (NDS) in working places set legally  at 5 mg/cu m, a 0.2 1.
 air sample must be  taken. In case of low nitrogen oxide levels
 in the atmospheric  air, taking 1. air sample will permit detec-
 tion of 0.1 mg/cu m, which is 50 times lower than NDS. There-
 fore, this latter volume is more satisfactory for use  in deter-
 mining the  presence of  atmospheric nitrogen oxides.  The
 precondition  for observations  within the 0.1 cu  m range is a
 series of  absorption tests  of  nitrogen oxides by  a  aqueous
 solution of sodium  hydroxide and  another series involving t
 reaction of  nitrites  with the Griess-  Illosway reagent. Color
 reaction is most efficient at pH 3. The error of the described
 method is plus or minus 95 for a sample containing 1-10 micro-
 grams nitrites.

. The use of helicopters for  collecting air pollution samples in-
 volves the difficulty that turbulence caused by the blades can
 distort the results. A study of  the flow configuration  around a
 helicopter showed that withdrawal of samples for air  pollution
 studies is optimum at a flight velocity of 50-80 km/hr.  and with
 the  sampler placed  1 m in front of the fuselage. In this case,
 sampling is not affected by the turbulence  generated by the
 blade rotation. An  aspirator  for  air inlet velocities  of  15-20
 m/sec was designed for  determining aerosol or gaseous con-
 taminants. The aspirator is equipped with a rotary pump and
 four sample inlets each equipped with a flow meter. The air
 flow rates in the aspirator can be adjusted from 0 to 3 i/min.
 The instrument was tested  for measuring the parameters of a

 special apparatus for use with this reaction is described, con-
 sisting primarily of a  spherical cell, described previously,
 which is used for  bubbling.  Comparative analyses  with the
 Guereau apparatus  (iodometric analysis) indicate  that  this
photometric method is sensitive to levels which are below the
olfactory threshold (0.026 ml  O3). At this low  concentration,
the air with ozone must be bubbled through the reagents for 30

The second part of a detailed review of techniques for measur-
ing the concentration  of air pollutants  deals with  various
parameters of the sampling procedure which affect the results
of all analytical methods. These parameters include: the dura-
tion  of the sampling period (or frequency of measurements),
duration of the study, season and time of day when the sam-
ples are taken, frequency of discontinuous sampling, air densi-
ty at the measuring sites, height of the sampling sites above
the earth,  and distribution of the sampling sites. The effects of
some of these parameters on determinations of atmospheric
SO2 and CO  are  shown by way of illustration. Sampling pro-
grams used in the German Federal Republic,  Great Britain,
and the USA (National Air Sampling Network and Continuous
Air Monitoring Program) are  described briefly. Finally,  some
of the problems arising  in the evaluation of  experimental air
pollution data are pointed out (such as  the skewed  rather than

analytical methods. A distinction is made between empirical or
discontinuous and continuous methods of sampling and it is
pointed out that only the latter can yield readily interpretable
results. In connection with gas sampling techniques, the value
of an impinger for increasing the rate of dissolution of gaseous
pollutants  is  discussed.  Methods are then described for the
quantitative determination of SO2, SOS, NO2, NO, CO, H2S,
HF,  and NH3, and brief mention is made of the techniques of
gas chromatography and flame ionization detection for traces
of organic compounds.  The two principal techniques for esti-
mating the total paniculate content of the air  are dust-fall and
dust-concentration determinations. The latter which depends

Because the use of plastic bags for the sampling and storage
of polluted air often  results  in  the loss of pollutants, various
plastic materials were compared with respect to their permea-
bility  to sulfur dioxide. The results are presented in a table of
permeability,  diffusion, and solubility constants. The physical
phenomenon of loss due to the diffusion and dissolution of the
gas is discussed. A  Mylar spherical 100-liter  bag  SO  micron
thick  containing air with approximately 1 ppm SO2 loses 1.6%
of the SO2 over 24 hrs in  an environment of 0  ppm SO2.
Materials  with a lower  permeability  for SO2 are  methyl
polymethacrylate, Lumiphane,  Vinyril, and  Nomex. In addi-
tion,  permeability is diminished  by the incorporation of a
metal into the film.

Electrochemical trace gas measuring units for determining the
concentration of pollutants in the open air are described. The
units  operate on  the principle of a  galvanic chain,  indicating
concentration changes of ions in a solution caused by reaction
with a sampled trace gas. The  sampling gas and the solution
are held by a solid electrolyte cast into a cylindrical silver tube
which serves an  an  anode.  The cathode is  embedded  in the
inner surface of the  electrolyte in the form  of a silver helix.
Electrical connections  for  both electrodes run  through  a
polyethylene  stopper at the  bottom  of the tube. The flow of
sample gas reaches the  actual measuring  zone, the inner sur-
face of the electrolyte, through  a glass line and a polyethylene
stopper at the top of the tube.  The  measuring  ranges of stan-
dard units extend from several ppb (dilution of  10 to the minus
9th power) to several ppm (dilution  of 0.000001, depending on
the gas component. Concentration cells are now available for
analysis of hydrogen sulfide, nitrogen dioxide,  nitrogen diox-
ide and nitric oxide, phosgene, hydrogen cyanide, chlorine,
oxygen, and ozone.

                         A rapid volumetric method is described for the determination
                         of sulfate ions in phosphoric acid obtained by extraction. The
                         method is based on direct titration of sulfate ion by barium
                         salt at pH 1.7-2 in a 40-50% alcoholic solution, in the presence
                         of Nitchromazo indicator and phosphate  ions. The determina-
                         tion time is 15 min. Because of its rapidity, dependability, and
                         accuracy, the method is recommended for serial analyses  in
                         the  control of phosphoric acid  production  by  the  extraction
                         process. It may also  be used with some modifications in the
                         analysis  of  phosphoric  fertilizers.  Automatization  of the
                         method is possible in the future.  (Author summary modified)

                         A new indicator, Nitchromazo, is used for determining sulfate
                         ions  by barium salt  titration in  the presence of two-fold
                         amounts  of  arsenate  and  thirty-fold  amounts  of  phosphate.
                         During titration in a 50% alcohol-water solution, Nitchromazo
                         interacts with barium in an acid range (pH 2.0) producing a
                         contrasting reaction and a sharp color change from a violet  to
                         blue. Nitchromazo is  synthesized by conjugation of  diazotized
                         4-nitroaniline- 2-sulfonic acid with chroraotropic acid in the
                         presence of Ca(OH)2.  For determining sulfates in the range  of
                         0.04 to 0.4 mg in the presence of arsenates (range 0.16 to 1.6
                         mg) or phosphates (range 0.2 to 2.0 mg),  one drop of 0.2%
                         aqueous solution of Nitchromazo is added,  together  with 10  to
                         15 ml of alcohol or acetone to a 10 to 15 ml solution with an
                         acid  strength of 0.01  M HC1 (pH 2.0). The solution  is then
                         titrated with 0.005 -0.01 M BaC12 until the violet color of the
                         solution changes to blue. With small amounts of sulfate, the
                         titration should be stopped at an intermediate color of the in-
                         dicator. The  molarity of barium  is  determined by a prior titra-
                         tion with sodium sulfate of sulfuric acid in  the presence of an
                         appropriate indicator.

                         An industrial chromatograph was developed for the analysis of
                         blast furnace top gas the components of  which are  hydrogen,
                         nitrogen, carbon monoxide,  and carbon  dioxide. The instru-
                         ment is constructed in two parts. The first part consists of the
                         measuring head, placed in an anti-deflagrating container and
                         controlled thermostatically to 1/10 C. This  unit is located as
                         near as possible  to  the  sample point. It includes the cell,
                         cocks, and columns  in the  upper section, and the electro-
                         valves for controlling the cocks and the  carrier gas supply
                         regulator for  the lower part. The  second section is the elec-
                         tronic unit (supply and programming). It includes the stabilized
                         supply for the measuring bridge, controls for temperature
                         regulation and auxiliary components, and the programmer and
                         sensitivity indicators. In the first unit, a column of silica gel is
                         connected in series with a column of 13x molecular sieves
                         The sample volume is introduced at the top of the column of
                         silica gel. Hydrogen,  nitrogen, and carbon monoxide are
                         separated  in  the  sieve column. After eluting  the  CO2  the

A  rapid  titrometric  method  for determining sulfur  in the
presence of phosphate  and arsenic ions utilizing the new bari-
um  indicator   Nitchromazo  (2,7-bis-(4-nitrc-2-sulfobenzol-l-

described. The test  compound is first decomposed  by the
Schoeniger method and then  titrated with barium salt in the
presence of the indicator. A sharp and  sensitive reaction with
barium  occurs at pH   1.7-2.0, eliminating phosphate inter-
ference completely and arsenate  and chromate interference,
partially. Such determinations exhibit a standard deviation of
plus  or minus  0.3. Analytical characteristics and  synthesis of
Nitchromazo are also described. (Author summary modified)

The  concentrations of  nitrogen  oxides in exhaust gas  emitted
from  oil-fired  boilers were  measured by using three kinds of
gas sampling apparatus, and the sampling method  for their
determination  in   flue   gas  was  examined.  The values  of
nitrogen oxides by the gas sampling apparatus prescribed in
JIS K 0104 agreed well with  those by direct gas  sampling
through capillary tube and by a bottle containing 22%  sodium
chloride solution as the trapping liquid. The concentration of
nitrogen oxides was invariable at any  sampling  point in the
same section of flue.  The  bubbler containing 0.1 N  sodium
hydroxide solution used for the  determination of nitrogen
dioxide in flue gas had high  absorbing efficiency for carbon
dioxide, and the volume of gas must be corrected for  this in-
fluence by titration of carbonate ion in the absorbing solution
after sampling. (Author abstract modified.)

NEW METHODS  OF CONTINUOUS TRACE  ANALYSIS.
(Neue Verfahren zur kontinuierlichen Spurenanalyse). Text in
German. Arch. Tech. Messen, no. 396,  p. 7-12, Jan. 1969. 2
refs.
A detailed description is  given of two electrolytic continuous
recording devices for measurement of small traces of gases
present,  for example, in atmospheric air. An earlier version
with a liquid electrolyte was based on Nernst's concept of a
concentration  chain. The new version uses an organic sub-
stance as an electrolyte which has a high dielectric constant, a
low electric resistivity, a low  vapor pressure,  is but slightly
hygroscopic,  and possesses  a  high  melting point. This elec-
trolyte is solid and is part of a monolithic, small  and  rugged
unit. The accuracies of measurements made by  these devices
vary between dilutions of  10 to the minus 9th  power and
0.000001, depending on the kind of gas. At present, the follow-
ing gases can be determined with these  accuracies: O2, O3,
C12, NO2, NO2 plus NO, H2S, HCN, and COC12.

CONTINUOUS DETERMINATION OF NITROGEN DIOXIDE
IN THE AIR WITH AN AUTOANALYZER.  (Kontinuierliche

For continuous  nitrogen dioxide  measurement  in  air, a
Technicon autoanalyzer  was  used.  A sample  gas flow was
drawn in through a reaction zone where it was brought in con-
tact with a Saltzman solution. After reaction with the nitrogen
dioxide,  the major part of the  solution went to a colorimeter.
The transparency of this  solution was measured  and recorded.
The following reaction zones were used: a siphon, a vertical
reaction  tube of about 60 cm length and 3.2 mm inner  diame-
ter, the gas sample and reagent passed in parallel flow, as well
as  in counter flow,  through the tube, a helical tube, and a
micro frit for continuous flow of the Saltzman solution. For
calibration, a continuously produced  mixture of NO2 and air
was used.  In all types of reaction zones, reliable NO2 mea-
surements  were obtained. The measured  concentrations were
found to  lie  in the maximum allowable  concentration range
(present  long-term maximum allowable concentration equal 1
mg/cu m).  With the 60 cm tube, it was found that neither the
flow velocity .nor the direction of -the gas sample had any in-
fluence on the  measured value. An adjustment time of-2 min
was required- for NO2 concentrations between 0.32 and 3.2
mg/cu m. In the 20 m tube,  adjustment took about 60  min at
concentrations between O.H  and U10 mg NO2/CU  m. For the
micro frit, a  low-volume container must  be used for the ad- •
justment period to remain short. The detection thresholds were
found to be 5 micrograms/cu m for the 20 m helical tube and
0.15 mg/cu m for the 60 cm tube. The only disadvantage of the
method is the complicated calibration process.

A RADIOMETRIC DEVICE FOR CONTINUOUS CONTROL
OF  FLUE DUST  CONCENTRATION.  (Ein  radlometrisches
Geraet znr kontinuierlichen Kontrolle des Gtehtstaubanfalls).
Text in German. Nene Huette, 14(4): 198-201, April 1969. 2 rets.
A radiometric method based on radiation absorption which can
be used for determining the flue dust  concentrations in fur-
naces is described. Gamma or X-rays are used for the mea-
surements. The equipment consists of a radiation transmitter
on one  side of the flue  duct  and radiation detector on the
other side. Since the ducts are rather thick-walled, drillings  of
8 and 25  mm  in diameter are  necessary; they are sealed by
windows.  The  measurements were conducted with a radiation
energy of 10 keV, and with an anode current  of 1mA. The
results are graphically illustrated by a plot of the radiation ex-
tinction as a function of the dust concentration. Since  the dust
composition was unfavorable with respect to the mass extinc-
tion coefficient,  absorption of the X-rays was  minor. Disre-
garding the fact that insufficient individual measurements were
taken, a dust measurement error of roughly plus or  minus 5
g/cu m was obtained. These measurements were taken on  an
experimental set-up, where air  was drawn through a pipe  to
which certain quantities of dust were added. To illustrate the
method in practical use, measurements were also taken in the
downward flue a furnace. Aside from dust deposition at the
radiation  inlet window,  no  problems  were  encountered,
although a final  conclusion must be  witheld,  since test mea-
surements are still being made.

THE DETERMINATION  OF ACIDIC GASES IN WORKING
ENVIRONMENTS BY ALKALI FILTER PAPER. (Alkali roshi
ho ni yoru sagyo kankyo chu sansei gas no  sokutei). Text in
Japanese.  Nippon Eiseigaku Zasshi (Japan J.  Hyg.), 24(1):49,
April 1969.
The alkali filter  paper method  for determining acid  gases  in
working environments entails  soaking  filter paper in a  30%
potassium  carbonate  solution,  drying the paper in  air, and
putting it  in a vinyl bolder having an exposure  area of 64  sq
cm. Absorbed gases  are  extracted with distilled water and
determined qualitatively and quantitatively. The required expo-
sure time is determined by the type  of acid being measured,
the production process, and the sensitivity of the determina-
tion method. Generally, 1 to 8  hrs are appropriate for acidic
gases like SO2, HC1, and NO2, and 8 to 24 hrs  for acid mists
of sulfuric, phosphoric, and chromic acids. One hour is usually
required  for SO2  measurements  by the para-rosaniline for-
maline method; the CL-Ba method requires 8 to 24 hrs. When
the relationship between the amount of SO2 adsorbed on the
filter paper and the average gas concentration in the  working
environment is plotted, a curve is obtained. Thus, on a per day
basis, the coefficient of conversion depends on the amount ad-
sorbed.  However, the graph for an hour of exposure time is
linear, suggesting that shorter  exposure times would be  con-
venient for the calculation.

                         Because of its increased  surface area in comparison to the
                         portion of the earth's surface it occupies, vegetation creates
                         conditions for catching a great amount of emmisions. The ratio
                         between the amount of emissions trapped and earth surface is
                         a significant indicator of tree damage and secondary air pollu-
                         tion.  Herbst found that entrapment of emission particles is
                         governed by space orientation of leaves on a plant,  by shaggi-
                         ness, by the number of individual plants, and by the size of in-
                         dividual emission particles. Chvapil  concluded that  the ability
                         of lindens, birches, and acacias to entrap particles is related to
                         leaf smoothness  and the  space orientation  of  leaves. The
                         present investigation shows that the ability  of Lazula albida
                         (Hoffm.) DC to catch emissions from rainfall is the result of
                         the shape of leaves and their orientation on the plant. Emis-
                         sions settle on the  leaves  of this plant, providing a mask for
                         necrotic markings caused  by toxic soluble substances. As in-
                         dicated by microscopic analysis, these substances originate in
                         products of industrial emissions. The amount of sediment and
                         the size of necrotic spots  is influenced by peculiarities of in-
                         dividual plants and plant ecology, as well as by emission con-
                         centration. A rough picture of pollution  of  the  lower at-
                         mosphere can be gained  from a study of this plant, which
                         predominates in European  woods.

                         In  order to prevent air pollution, measurement of pollutant
                         concentrations must be continuously performed. In this report,
                         both continuous monitoring and manual analyses of typical air

                         tinuous   methods  and  apparatus.   Sulfides  are  measured
                         manually by colorimetric  analysis with rosaniline  or barium
                         molybdate, by the lead per  oxide method, or by  test paper
                         methods. Sulfides are also measured continuously by means of
                         solution conductance (Thomas autometer) or  by optical ab-
                         sorption with rosaniline or with iodine-starch. Carbon monox-
                         ide is measured manually  with palladium sulfate and ammoni-
                         um molybdate, by gas  chromatography,  or  by the hopcalite
                         method. It is measured continuously by infrared or ultraviolet
                         absorption of reduced mercuric  oxide. Nitrides are measured
                         manually by the Saltzman or the Jacobs method,  or with
                         ortho-tolidine sulfate. Hydrogen  sulfide is measured manually
                         by methylene blue and continuously  by  a colorimetric  filtei
                         paper method. Hydrocarbons are measured  manually by gas
                         chromatography  and continuously by flame ionization detec-
                         tors. Formaldehyde is measured manually by colorimetric anal-

Deterioration of pine forests near industrial complexes on the
Tyrrhenian and Adriatic seacoasts of Italy led to systematic in-
vestigation of air pollution.  Chief offenders were  found to be
the sulfur and nitrogen oxides. To build a sampling network
meant developing a practical method, easily reproducible and
low hi cost. The method of  Syozo-Fukui, using a filter soaked
in a concentrated K2CO3 solution, seemed  best.  Analysis of
the filter permits determination of SO3, the oxides of nitrogen,
and chlorides. Results were good when the relative humidity
was below 70%. The filter  salt was highly deliquescent, and
above 70% humidity significant quantities of test substance
escaped. Therefore, a  framework  equipped with an  in-
terchangeable  condenser and sheltered by an acrylic plastic
casing, the whole being enclosed  in a meteorological shelter
was provided  to  hold  the  filter. For  transportation  to the
laboratory, the filter was sealed hermetically in polyethylene.
The method of Fukui was  used for nitrogen  oxides, but for
SO3 that of Johnson-Nishita was preferred: reduction  of all
sulfur compounds to hydrogen sulfide,  measured colorimetri-
cally with methylene blue  to a  sensitivity of 0.2 ppm.  A
Schleicher 589 filter was used immersed in  K2CO3  solution
and dessicated hi a vacuum. At  the laboratory, nitrogen ox-
ides,  sulfur,  H2S,  and   sulfides  were  determined  spec-
trophotometrically. Agents  used for determining nitrogen ox-
ides were sulfanilamide, naphthylethylenediamine, hydrochlo-
ric acid, and a standard solution of N02.

The weight of small particles can be measured by  the use of a
cascade impactor within the smoke duct. The cascade impac-
tor used in this case had a series of six nozzles, the diameters
of which ranged successively from 0.526 to 0.112  cm, and the
distance between each nozzle and its collection plate was fixed
at three times the length of the nozzle diameter. A milliporc
filter was used after the smallest nozzle to collect the smallest
residual particles. The experimental particles were fly ash and
mica powder. Particles of all sizes were sent from the largest
to the smallest nozzle. At each stage, all particles larger than
the nozzle diameter and 50% of those having the exact size of
the nozzle could not pass through and were collected on the
plate;  the smaller particles all passed through, and the process
was repeated  at each  nozzle  until the millipore filter was
reached. It was found that a partial separation efficiency curve
obtained with an aerosol of a single kind of particles can be
adapted  to  aerosols  containing  many  types of particles.
Separation  efficiency was  reduced  by backscatiering; the
minimum weight of collected particles which causes backscat-
tering increased with particle size. The diameter of the aerosol
particles can be measured by using a cumulative separation ef-
ficiency curve.

The Sundsvall aluminum plant, the only  alumina-electrolysis
plant in Sweden, operates 300 cells currently producing 65,000
tons of Al per year, representing a fivefold increase of produc-
tion since 1962. To date the company has spent  20  million
kroner (about $4,000,000 in  1969)  on air  pollution  control
equipment, but  there is still some damage to vegetation  from
hydrogen fluoride gas. Comfort of workers requires 20 to 30
changes of air per hour (12 million cu m/hr) in pot-line  area,
which complicates air pollution control. Most recent of several
air-washing devices used in  a 'spin bath' in which plastic balls
are sprayed with water from jets. Exhaust  gases  escape
through four 70-m concrete chimneys, 10-11 m in diameter and
lined internally  with plastic. The equipment removes  90% of
water- soluble  fluorides  from  exhaust. The  company also
maintains  160 inspection stations in the area, which by means
of pollutant- sensitive plants  record the  immission of  toxic
material, which is the basis  of a map of Sundsvall region with
'isofluoride' lines to indicate pollution zones.

DILUTION SYSTEM  FOR LOW  CONCENTRATIONS OF
NITROGEN DIOXIDE  AND  DETERMINATION  OF  THE
SALTZMAN FACTOR.  (Dosierung kleiner Stickstoffdioxid-

German. Z. Anal. Chem., vol. 244:294-302, 1969. 40 refs.
A dynamic flow system is described by  which  dinitrogen
tetroxide (N2O4) is diluted with air in two steps to obtain NO2
concentrations in the ppm range. Through thermostatization of
the first  stage,  the dissociation of the dinitrogen tetroxide
could be taken into account during calculation of the NO2 end
concentration.  With  the  NO2/air mixture obtained by  this
method, the Saltzman photometric analysis of N02, which is
based on the formation of  an intensely colored azo dye was
tested. The results obtained with  gaseous  NO2 and  with
equivalent amounts of aqueous nitrite solution are compared.
At a concentration of 1.5 micrograms NO2 per 25 ml absorbing
solution, the dye formation by 1 mole NO2 equals that of 1
mole of nitrite ('Saltzman-factor' 1.0). If the concentration is
10 micrograms/25 ml, the intensity of the color effect due to 1
mole of NO2 equals 0.86 moles of nitrite ('Saltzman-factor'
0.86). Only half  the expected color intensity was found  when a
NO2/air mixture was used that had been prepared by a dynam-
ic two-step dilution and oxidation  of NO ('Saltzman-factor'
0.5).

platinum electrodes.  Model 68-5 records the density  of  sul-
furous gas through the amplifier. Its attributes include the fol-
lowing: relatively small size; light weight compared to the con-
ventional types; and  prompt measurement in a short time (10
minutes average time required). The sample cell is made of
glass. The reagents used for the test were 1 1 water with 30%
hydrogen peroxide and 1 ml of 0.01 N  sulfuric acid. A stan-
dard solution of sulfurous gas  was used for calibration. The
test covered the determination  of a standard graduation; ex-
amination of the fixed zero point;  constant air flow test; ex-
amination of sensitivity calibration; rosaniline test; and a com-
parison of Model 68-5 with instruments made by other compa-
nies. Model 68-5 was observed to have stable electric systems
and a slight sample air fluctuation.  Based on the trial test car-
ried out for five consecutive days. Model 68-5 was considered
to constitute  a  continuous measurement  for a  considerable

A general classification of dusts in dust  fall and  suspended
particulate matter was presented with an emphasis on sampling
and  measurement devices.  Various  types  of instruments
described are practical and recently developed for dust mea-
surement. The widely used devices  for dust fall measurement
are the deposit gauge and dust  jar.  For suspended  particulate
matter measurement, the tape sampler,  high-volume sampler,
and  digital dust meter  (automatic recording system) were
discussed. The Andersen Dust Sampler was described. The
results of a comparative study on the  numerical  values ob-
tained by several types  of  samplers, conducted in  July, Sep-
tember to October of 1968, and January of 1969 indicated a
proportional relationship among the numerical  values. Five
kinds  of samplers  were  examined:  high-volume sampler,
cyclone high-volume  sampler, tape  sampler, digital dust meter,
and  digital dust meter proofer. Daily averages measured by
tape sampler had a  close correlation with those of the high-
volume sampler. The proportional relationship of total average
was found to be 1 C(ohs)/1000  ft equals 100 microgram/cu m.
Results of the digital dust meter for respirable dust movement
were included.

Gas separation  was  carried out in two stages,  condensation
and sublimation, in a small metal tube exposed to  a tempera-
ture gradient from 77 to 300 K.  A non-condensable gas such as
helium, hydrogen or  nitrogen was used as a carrier.  In the first
stage,  the  components of the  mixture  were  selectively
solidified in  the cooled  tube  under partial pressures below
those of the triple points. In the second stage, heating of the
tube with an inverted temperature gradient caused sublimation
and completes the  separation.  Catharometers or mass spec-
trometers were employed for the detection and determination
of the gases.  Gases could be determined in  the range of
0.000001 to 0.0001 mole/ml of gas. (Author abstract modified)

                         METHODS RECOMMENDED  FOR THE MEASUREMENT

                         A standard method, suited  to  South African conditions, for
                         measuring  atmospheric   sulfur  dioxide   concentrations  is
                         described. The method is based on the reaction between sulfur
                         dioxide and hydrogen peroxide. The principle of the hydrogen
                         peroxide method consists of drawing a measured volume of air
                         through a gas-washing bottle containing a dilute solution of
                         hydrogen peroxide.  The resultant increase in acidity of the
                         solution is determined by titration using a pH meter, and the
                         sulfur dioxide concentration in the air is calculated from the
                         amount of titrant used. The method is  not specific because it
                         also measures gaseous acidity; it is affected negatively by am-
                         monia  and positively by  acid or acid-forming compounds
                         present in the air. Normally the concentrations of these inter-
                         fering substances are much  smaller than those of sulfur  diox-
                         ide  and can be ignored. The measurement of sulfur dioxide
                         can  be  combined  with  the  measurement  of smoke  and
                         suspended matter primarily by drawing the air stream through
                         a filter paper. The apparatus used for sampling is inexpensive
                         and simple to use.  Despite its nonspecificity, the hydrogen
                         peroxide method is the simplest and most suitable for measur-
                         ing  sulfur dioxide and is recommended  for the  continuous
                         measurements.

                         Effective measures  against  air pollution require  an extensive
                         knowledge  of the type, origin, distribution, and effect of air
                         pollution. Many  complex interactions are uncovered by emis-
                         sion measurements  and  their evaluation. The  potential of
                         modern measuring techniques are discussed and illustrated by
                         examples  from  the  air  monitoring  program  of  the  Far-
                         benfabriken Bayer AG, where more than 20 automatic emis-
                         sion measuring units for  various gas components  have  been
                         erected. Characteristic parameters of emission concentrations
                         are obtained  by plotting cumulative frequency curve over a
                         logarithmic abscissa. A 50% value of the cumulative frequency
                         curve indicates the most probable emission to be expected for
                         recovery periods after the occurrence of peak concentrations.
                         The peak concentrations are characterized by the 95% value of
                         the cumulative frequency. The numerous data supplied by au-
                         tomatic monitoring units is  rapidly digested by this statistical
                         method.  The data obtained permits a classification according
                         to certain criteria, such as  the influence of wind velocity or
                         direction, weather conditions, the time of day or season  etc.
                         Half-hour emission  values are correlated  with wind direction
                         data to provide information  on the origin of emissions. Further
                         valuable information  on  emission sources is  derived  from
                         direct  evaluations of  simultaneous measurements  of  several
                         gas components. These parallel measurements help to distin-
                         guish emissions  from combustion processes in  the open air
                         from other emissions and provide information on the fuel used
                         in the particular instance.

The  intensity  of odors caused  by automobile exhaust  gases
was  evaluated by measuring the odor intensity of dilutions of
the  exhaust  gas with  fresh  air  that  exceeded  the  odor
threshold. The tests were performed with a water-cooled four-
cylinder, four- stroke Otto  engine. The measurements  were
based on the following considerations. At low traffic density
i.e.,  on well-ventilated streets,  the exhaust gas odor is not
noticeable;  the odor threshold is not reached.  With increasing
traffic density, i.e.,  less ventilation,  odor threshold is ex-
ceeded. The  mass flows emitted under the  latter condition
were indicative of the dilution which was the measure for the
odor intensity. The results showed the familiar independence
of carbon monoxide and hydrocarbon concentrations from en-
gine  operating state.  Test personnel could smell the exhaust
gas independently of the operating state at 800- to  1000-fold
dilution.  The carbon monoxide and  hydrocarbon  concentra-
tions  at the moment the odor threshold was  exceeded  were
between  I and 100 ppm and 0.6 to 8 ppm, respectively.  Addi-
tion  of air  in the exhaust system reduced the  concentrations,
but increased the odor intensity.

After reviewing the  theoretical principle  of amperometry, the
determination of substances such  as oxygen, chrotnate,  nitric
oxide, and sulfur dioxide  by this  method is  discussed. Two
metallic electrodes submerged  in the solution  to be analyzed
are used. It is important that the reaction at the electrode is so
rapid that only the substance transported from the solution to
the phase boundary determines the reaction speed. The elec-
tric current at the electrode is then directly proportional to the
concentration of the substance to be measured. For measuring
nitric oxide, amperometry has the disadvantage that at concen-
trations of  more than 2%, the substance transport is so  rapid
that  the current  density no longer depends on the concentra-
tion. In this case, it is better to use chronocoulometry. Poten-
tial is applied in jumps to the electrode instead of the stationa-
ry current and the current flowing within a certain time  inter-
val after the jump is integrated. For measuring SO2 in waste
gases, waste gas enters a solution of 0.5 m sulfuric acid and
0.05  m potassium bromide  at constant speed. Current enters
the solution via two platinum electrodes. Bromine develops at
the anode and is reduced by the SO2. The redox potential of
the solution is measured with a third platinum  electrode and a
reference electrode.  Minimum concentrations of 0.1 to 1 ppm
and maximum concentrations of 1 to 10 ppm can be measured.

Measurements of  air  pollutants  are  roughly classified  as
chemical, physical, and biological. Chemical measurements are
subdivided  into test-paper, colorimetric, test  tube, titration,
gas volume, weight methods, etc. Physical methods are subdi-
vided into mechanical, electrical, and optical method. Biologi-
cal measurements make use of the human nose, small animals,
and plants. The measuring methods are also classified accord-
ing to time interval into integral, instantaneous,  and continu-
ous measurements. The collection method for  test samples is
divided into absorption tube, vacuum substitution, air substitu-
tion, liquid substitution, and automatic continuous gas sampler
method. The absorption tube method and gas sampler used by
National Air Sampling Network of the U. S. are discussed in
detail. Sulfur oxides are measured by  the West and  Gaeke
method, the lead dioxide method and recorded by the  electric
conductivity method. Nitrogen  oxides are measured  by the
Saltzman method, the Yacobs method, and test tube methods,
and recorded by an automatic recorder. Hydrogen sulfide is
measured by the methylene blue method and recorded by an
automatic recorder. Carbon monoxide is measured by hop-
calite according to a test tube method, detected  by Kitagawa
detector, and recorded by an automatic  recorder. Ozone is
measured by iodimetry, phenolphthalein, ferrous thiocianate,
the gum crack method, and an ozone meter. The operation of
each instrument is reviewed.

The presence of  phosphorous-  and sulfur-containing  com-
pounds  in air is determined by spectrophotometric measure-
ments of the coloration of hydrogen flames produced by the
injection of gas, which contains oxygen or is  mixed with ox-
ygen, in a hydrogen stream. More hydrogen is provided than is
necessary for complete  conversion of oxygen. The  flame
coloration is measured in a dark zone at some distance from a
first flame where the intensity of the background glow of the
flame is negligible  over  the intensity  of flame  coloration.
Phosphorous compounds are determined in a  zone of one to
two flame  lengths distant from the first  flame;  sulfur com-
pounds, in a zone five to fifteen flame lengths distant. Equip-
ment required for measurements include quartz or glass capil-
lary tubes;  a cylinder for enclosing the hydrogen  flame, which
is preferably cooled by water; and the spectrophotometer for
measuring flame coloration in the  spectral range around 520
micron for phosphorous-containing compounds  and 380 micron
for sulfur-containing compounds.

The phenomenon that  a  liquid gas (sulfur dioxide, nitrogen
dioxide, propane, butane) permeates  through  the tube wall
within a teflon tube at  a  constant rate was  studied. The tube
had an internal diameter of 0.062 in., a wall  thickness of 0.012
in., and an internal  temperature of 20.1  plus or minus 0.1 C.
The permeation rate of 25 C was 0.58 micrograms/min/cm. By
the use of these permeation tubes, a dynamic calibration of
automatic  SO2 or NO2 measuring instrument, an evaluation of
the characteristics of SO2 monitoring instrument,  and an  ad-
justment of automatic NOX measuring instruments  can be per-
formed.

Of the harmful elements released into air,  dust particles  are
removed  fairly easily by common apparatus. The  removal of
gases except sulfur  dioxide or carbon monoxide, however, is
difficult,  and  little  progress has  been made.  Gas analyzers
used in Japan for measuring gaseous pollutants in air include a
continuous  measurement recorder  for  sulfur  oxides  and
nitrogen oxides, a continuous automatic recording analyzer for
carbon monoxide, and a filter tape harmful gas analyzer. After
collection  and  condensation, the  pollutants are analyzed  by
polarography,  gas chromatography,  infrared  absorption,  ul-
traviolet  spectrometry,  and mass  spectrometry.  The recent
trend is the  use of continuous  automatic analyzers because of
the high cost of labor. Operating principles and manufacturing
companies of the instruments were described in detail.

QUANTITATIVE AND ISOTOPIC  DETERMINATION  BY
MASS  SPECTROMETRY  OF  GASEOUS   COMPOUNDS
PRODUCED DURING DENITRIFICATION.   (Determinatio
quantitative et isotopique, par spectrometrie de  masse,  des
compose  gazeux  produits  dans la denitirification).  Text in
French. Chim. Anal. (Paris), 52(l):53-56, Jan. 1970.  8 refs.
Theoretically  'denitrification' is defined as the reduction of
nitrates present in the soil to the state of molecular nitrogen.
However, in practice,  its definition  is broader in that it in-
cludes the reduction of the nitrates to the gaseous state,  ex-
cept ammonia, by biological or chemical processes. Existing
methods  of determining  the products of denitrification  are
discussed  with respect to their shortcomings.  A  mass, spec-
trometric  method of determining  nitrogen and nitrous, oxide
emitted by the soil in the course of its denitrification is simpler
and more  rapid than the previous ones. The incubator used in
                        the tests is hermetically sealed and contains a known amount
                        of soil in a pyrex jar which is in contact with an attachment
                        containing a concentrated solution of soda to absorb the CO2
                        released by the soil. The pyrex jar can be connected by turn-
                        ing a ground  cock  with a semi-capillary U-shaped  tube im-
                        mersed in liquid  nitrogen, in order to trap condensable gase
                        (residual CO2  and particularly N2O). This trap can be shut off
                        by cocks on both sides. In most cases, 20 g  of soil saturated
                        with water was used to which 1% of glucose and 15 mg of
                        nitrogen in the form  of  KN03 enriched 30%  by  the  15N
                        isotope was added. The incubators were kept at 25 C in an
                        oven and their atmosphere was periodically analyzed by a
                        Varian Mat model GD  150 mass-spectromete The isotope con-
                        tent of the gaseous  compounds with two N atoms can b mea-
                        sured in three different ways. The quantitative determination
                        of the amounts of N2O and N2 are described and discussed in
                        great detail and a typical example is given.

                        A method for determining the nitrous oxide concentrations in
                        small blood samples (0.1 to 0.5 ml) by gas chromatography is
                        described. The method combines the vacuum extraction by
                        van  Slyke with the sample dispatcher,  a four-way cock, by
                        Farhi et al. The reproduceability of the method is better than
                        0.5%. The method was used for estimating cerebral blood flow
                        and  for  determining  the  uptake  of nitrous oxide  by the
                        cerebro-spinal fluid. Five dogs were anesthetized and the N2O
                        concentration  in the arterial blood  as well as in the  blood of
                        the sinus sagittalis  was determined.  For an average arterial
                        CO2 tension of 56  ton, the average  cerebral blood flow was
                        46.8  ml/min/100  g  and  the  oxygen  consumption  of the
                        cerebrum was 3.2 ml/min/100 g. The uptake of N2O by the
                        cerebro-spinal fluid was much  slower  than in  the venous
                        blood.

                        A centrifugal  wind  sifter wind rotating  zig-zag channels was
                        developed for grain size analyses. It can be used for grain
                        sizes from 1.5 to 8.0 micron and for materials with a density of
                        2.7.  The  unit  has throughput of 0.5 to 3 kg/hr. The sifting
                        process  comprises of  dosing  - dispersing and separating the
                        fine and  coarse  material from the carrier gas. The material
                        which is to be sifted is filled  into a wide-necked bottle which
                        is tightly attached to the charging device. The  latter consists of
                        a screw conveyer and an agitator. A blower injects about 55 to
                        60 standard cu m air/hr. The desired sifting range can be ad-
                        justed by varying the rpm of the sifting wheel  and the air
                        quantity according  to  a calibration curve. The discriminating
                        effect of the wind sifter and the reproducibility are good. Even
                        material  with a strong tendency  to  agglomerate  can be
                        separated.            '      '

CURRENT VOLTAGE CHARACTERISTICS OF SOME TYPI-
CAL   THERMO-IONIZATION  DETECTOR   SYSTEMS.
Preprint, Czechoslovak Acad. of Sciences, Brno, Inst. for In-
strumental and  Analytical Chemistry, 30p., 1968 (?). 14 refs.
Translated from German. 32p.
Current  voltage characteristics  of  metal types of  thermo-
ionization detectors were measured  and compared with the
characteristics of the solid glass detector. The influence of the
complete  shielding on  these  characteristics  was determined.
The mutual influence of the systems for a combined detector
was manifested in all cases by the changes in the size and the
character of the signal of the flame ionization detector. These
changes were caused by the polarity of the electrodes and the
construction, in some cases the material, of the detector. The
response signal of the  thermo-ionization system of the  com-
bined detectors was  a  function  of the  distance between the
two systems, and  the  latter  was always  lower at the  same
degree of ionization  effect than was the case for a simple
ionization detector. The fusion temperature of  the salt of the
alkaline metal was the main factor influencing the current volt-
age characteristics  off the simple ionization detector. A  com-
parision of electrical heating of the fused-salt carrier of the al-
kaline  metal  with  the  heating  by means  of flames demon-
strated that the advantage of  electrical heating  does not lie in
the elevation of the response signal, but rather in the possibili-
ty of control of the basic ionization current, independently of
the flow of hydrogen. (Author abstract modified)

INVESTIGATION AND APPRAISAL  OF FLU-GAS DAMAGE.
 (Untersuchung und Begutachtung von Rauchschaden. Part I.),
Translated from German. Hamburg  Staatsinstitut  fur Ange-
wandte Botanik Jahresbericht, 5(119-120), 1938.  3 refs.
Plants  exposed to flue  gas  showed definite  damage  from
fluorine (F) and acids of sulfur and nitrogen. A crystalization
method utilizing the microscopic  identification of silico-sodium
fluoride proved best for qualitative fluorine analysis of the 102
samples examined  through 1936. As in  previous studies, the
samples tested showed that F was taken  in through the branch
bark and leaves of cherries and pears. For  the first time,  how-
ever, the fruit itself was damaged and F  detected there. Black,
hard disks had  formed  around the flower and in the  fruit ad-
jacent  to  the flower. Samples examined  long after damage
took place showed no F present. Twenty-one samples were ex-
amined for acid damage. Large concentrations of nitrates were
detected in the  specimens by  means of the diphenylamine-sul-
furic acid reaction. Different plant species showed  markedly
different sensitivities to flue gases.

THE RESULT  OF OBSERVATION  ON  PLUME RISE.  (Hai
Gasu  Joshoko  No Jisoku  Kekka.)  Meteorological  Research
Inst.,  Tokyo (Japan). Applied Meteorology Laboratory,  14p.,
1968. 5 refs. Translated  from Japanese.
The plume rises from industrial chimneys 55, 90, 120, and 170
meters in  height were examined  and  attempts made to fit the
empirical data to existing correlations for dispersion and effec-
tive stack height.  These were used to describe the spreading
pattern of the high-temperature plume as it left the stack, an
important factor in determining the pollutant concentration on
the ground. Photographs of  the tracer-colored plume  were
taken at 40-second intervals. The axis of smoke flow was ob-
served from a helicopter. Additional observation points on the
ground gave  sufficient data to calculate trigonometrically the
position of the trail. The plume temperature and rise velocity
at the stack exit, and the wind velocity, were also determined.
The Priestley equation for plume rise was used for the deter-
mination of  the  maximum  rise height for heat-dependent,
neutral-layered conditions, and for a stable condition.  It was
found that stacks taller than 100 meters contacted atmospheric
layer  movements  and  had practically no unstable condition.
Empirical findings were compared with results calculated from
the Holland (Oak Ridge), Bosanquet, and Priestley equations.
The Holland  correlation was satisfactory for large heat emis-
sions,  and  the  Bosanquet equation gave inconsistently  high
values. The Priestley equation was good for small heat emis-
sions.  When  empirically corrected for wind velocity, stack
height, and heat emission, the correlation gave  the plume rise
in terms of experimentally determined factors for netrual layer
conditions.

Experiments  were conducted on sampling polydisperse  dust
particles  up  to four millimicrons in diameter. The particles
were blown down a vertical wind tunnel and sampled at three
different kinds of head at velocities that were equal to 0.5, 1.0,
and 2.0 times the  wind velocity. The relationship between the
ratio of the  apparent to true concentration and the ratio  of
sampling to wind  velocities was found  to agree with a previ-
ously reported expression. Isokinetic sampling  is essential to
obtain correct concentration values; the error is smaller when
the sampling  velocity is too high than when it is too low. The
shape of the head was not important and changes  in particle
size  distribution due  to anisokinetic sampling were not  de-
tected.

The operating principles and applications of the  infra-red rapid
scan monochromator are described, particularly in its applica-
tion to the gas phase reaction of nitrogen oxide. A monochro-
mator of the  type described can repeatedly record  3-150 spec-
tra per second. It performs most satisfactorily measuring reac-
tions of short half-life time, in the range from 1-60 seconds.
Two slightly different units are described; one is commercially
available, the other is an experimental device. A reaction cell
for mixing  the  reactants to be  studied is  described.  Several
sample reactions  are  analyzed to serve as examples of  the
abilities of the method.

The results of a parallel study of the size distribution of drops
of a modeled nebula are presented. The information is ob-
tained  by a  sedimentation analysis and by the microphoto-
graphic method in  order  to illustrate the advantages of the
former. The sedimentation method of analyzing the degree of
dispersion of a modeled nebula gives a completely clear and
precise  representation of the size distribution of the drops in
it. It can be used to study natural and modeled clouds and
nebulae, and is less cumbersome than the microphotographic
method. (Author abstract modified)

The isopropanol or absorption method of Corbett and Flint,

method determines the SO3 content in flue gas accurately. The
NaCl method yields approximate  values.  The complex sam-
pling  and analyzing apparatus for the  Corbett-Flint method
have no relationship to the low accuracy achieved with this
method. Sulfate containing fly dust commonly found in soft
coal smoke  interferes with the determinations. Sulfur dioxide
can be  determined at either  the  condensation or the  Nad
method simultaneously with the SO3 by absorption in H2O2
and subsequent acidimetric titration.

problems or to cause plant damage and corrosion to buildings-.
Some of the methods have been checked and tested extensive-
ly in the laboratory and in the field. Others have not yet been
widely tested but are included for their potential usefulness in
laboratory studies.  The methods  include the measurement  of
dust collected by the deposition method with respect to tars,

                         A  method is proposed for measuring the  amount of carbon

                         cycle consists of 15 operating stages (idle, acceleration,  cruis-

                         fusion and behavior, and influence on public health and econo-
                         my were compiled. The most important sampling equipment or
                         materials were described. Air  pollutants were classified as
                         aerosols, smoke,  fumes,  dust, fog,  smog, gases,  and odors.
                         Tests for airborne  pollution included a Guecker's counter,
                         Mununa's  aerosol   analyzer,   Ringelman   charts,  and  a
                         smokescope.  Aerosol collection methods discussed were sedi-
                         mentation containers, deposit gauges, filtration, centrifuging,
                         thermal precipitation, electrostatic precipitation, and impact
                         sampling. Sampling of gaseous or vapor phase pollution was
                         separated into quick and precision methods. Quick methods in-
                         cluded the peroxide weighing method and the hydrogen perox-
                         ide volumetric method. Precision methods included absorption,
                         adsorption, freezing, and  withdrawal  of gaseous  samples  in
                         vacuum, containers. Infrared and ionization chamber analyzers
                         were also  discussed. Microbic air  pollution was described.

AIR ANALYSES FOR DETERMINATION OF THE FTLTRA-

The  theory of filtration capacity, based on the capability  of
forests to filter air and smoke damage by means of air analy-
sis,  was  investigated.  The  investigation was  based  on the
'pararosaniline'  method using the measuring box (Messkoffer)
which is sensitive to the presence of sulfur dioxide  in the air.
It permits evidence of short-term, very slight variations in sul-
fur dioxide concentrations by means of short-term sampling  of
the duration of eight to 10 minutes. The methodology aims  at
comparing the measurements for an unforested area in front  of
the forest with results in the interior of the forest obtained  at
various  distances from the smoke emission  source  in the
direction  of  the wind. The meteorological factors such  as
direction and  velocity of winds, temperature, relative humidity
of air, visibility, and cloudiness were taken into consideration.
The  results obtained show that the sulfur dioxide content in-
side  the forest, and  comparatively  far from the smoke emis-
sion  sources,  fluctuate greatly. The distribution of these fluc-
tuations over  a period of  time arise both convectively and ad-
vectively;  they  are  often  periodic.  Assuming a  retarded
exchange in the above-ground layer of air, the air samples in-
side  the forest showed from time  to time higher  concentrations
of sulfur dioxide in comparison to  the free terrain. It is con-
cluded that the filtration capability, so far attributed to forests,
does not correspond to the actual state of affairs to  the extent
so far assumed.

An empirical  characteristic calculated only from the individual
concentrations above the arithmetic mean is used to describe
the frequency distribution  of sulfur dioxide concentrations.
This empirical characteristic, 'so', is identical to the standard
deviation,  V, of individual values in the case of normal dis-
tribution; however,  it deviates more markedly from V the
more asymmetric the distribution. A comparison between dis-
tributions found at 20 measuring places and  those  calculated
from V show a statistically valid agreement.  The empirical
characteristic  can therefore be employed to assess a breach  of
emission limits. (Author summary modified)

A filter cartridge based on the suction principle and consisting
of a layer of quartz wool prepared with a solution of Ag2SO4
and  KHSO4  was  developed  to absorb  hydrogen  sulfide,
hydrogen chloride, and ammonia, the substances  which inter-
fere most with air quality measurements of sulfur dioxide. The
cartridge absorbs the interfering compounds during sample  in-
take almost completely at air throughputs of up to 180 liters an
hour without also absorbing the SO2, and is therefore suitable
for automatic SO2-measuring  devices operating on  low  air
throughput as well as for manual methods. Experiments are  re-
ported investigating in further detail the suction of H2S in the
filter cartridge and SO2 uptake by the cartridge. When conven-
tional sampling techniques are used for the Silikagel and TCM
methods of manual SO2 measurements, SO2 values are not
distorted by the filter. Instructions are given for its preparation
and installation in the sampling device.

The apparatus and  experimental procedure are described for
the simultaneous  but separate  determination  of the chemilu-
minescence and fluorescence of reactions. With this  method,
the samples under study are radiated with ultraviolet light im-
pulses from  which only  monochromatic radiation of wave
length 3650 A is filtered. The emissions produced by chemilu-
minescence, in the form  of continual components, and  by
fluorescence,  in the form of superimposed alternating current
components,  are  registered separately and  measured by a
photostream amplifier which does not  receive any ultraviolet
light at all, since the excitation line of 3650 A is totally ab-
sorbed by additional filtering. The method was applied to ex-
periments  on  the  chemiluminescence  of  thiocyanate  B
produced by ozone. In contrast to results in the literature ob-
tained with conventional  neutralizing  agents,  the effect  of
ozone on thiocyante B in an amylacetate solution produces a
blue-green chemiluminescence by a blue-green fluorescence.

for the presence of the suspected ions and their effect on the
conductivity of the solution determined. Ions considered were
SO4(-), Cl(-), K(+), Na(+), Ca(++), NH4(+),  Mg(++), and
NO3(-). Densities  of  each ion were  obtained using  ion
exchange analysis techniques. A 5% density fluctuation coeffi-
cient was observed as a result of the adsorption of these minor
constituents. The conductivity  ratio of the  original absorbing
solution was  determined to be  24.4 micro-ohms/cm.  A dif-
ference of 0.4 micro-ohms/cm was observed for the test solu-

in an attempt to evaluate different methods of observation of
aerosol extinction and in order to improve upon the techniques
wherever possible. Simultaneous observations at different al-
titudes are necessary for a further investigation of the aerosol
correction.  A  comparison  of the data should be carried out
with narrow  light filters and instruments of  the same type,
since in the opposite case  the Forbes effect greatly decreases

Systematic measurements of dust pollution were conducted
simultaneously by the aspiration and sedimentation methods in
10 Polish cities during 1966 and 1967. The aspiration method is
based on the day-long aspiration of air  through a glass fiber
filter;  the  concentration of dust is  determined by the  dif-
ference in weight of the filter before and after collection. In
the sedimentation method, glass jars are exposed for a month
and the dustfall  is weighed after washing and  drying. The dis-
tributions  of  the measurements indicated a rather close rela-
tionship between the two sets of measurements obtained by
each of the two methods. Equations are presented by means
of which measurements obtained by either method can be con-
verted to results which the other method would have yielded.
They can also be used  to approximate the concentrations of
atmospheric dust in  a city from available  dustfall data. The
dust concentrations in the cities studied were highly correlated
(the correlation  coefficient equalled 0.78), indicating that the
ratio  of the  amounts  of  relatively  precipitable  dusts  to
suspended dusts in large cities is  comparatively stable. Distinct
differences in the chemical composition  of dusts, depending
on the degree of dispersion, were found. The  steadily  sedi-
menting  dusts  contain  significantly  smaller  quantities  of
benzene-extractable  substances  and  lead compounds as do
suspended dusts.

                        determining very low concentrations of compounds in gas mix-
                        tures, a combination of photometric analysis and the reaction
                        of the gas and liquid  is used.  Instruments based on the elec-
                        trolytic conductivity change of liquids after reaction with glass
                        are also suitable for measuring low concentrations in gas mix-
                        tures. Depolarization  and polarographic instruments use the
                        electrochemical reaction on  the polarized electrode immersed
                        hi the liquid. In coulometric instruments, the compounds are
                        electrolytically oxidized with bromine or iodine. This method
                        is  used  to  measure  SO2,  hydrogen sulfide,  mercaptans,
                        thiophenes, thioethers, organic sulfides, and olefins. For mea-
                        suring  high concentrations, the election of instruments for
                        each compound is broad and the selection of the most suitable
                        instrument depends on other conditions, especiall on the type
                        of other impurities.

sulfur. The organic  substances present were tannides, car-
bohydrates, nitrates,  pektins, polysaccharides, and substances
soluble in ether. During the extraction of  needles injured by
smoke,  the extract  received all these substances in higher
amounts  than when processing healthy needles. A correlation
was  established between the amount of extracted sulfur and
ashes and light absorption by the extract. Increased extraction
of tannides from  the smoke-damaged  needles can be utilized
as a  new qualitative  test to determine  the effect of smoke on
spruces. The turbidity itself is formed by  a mixture of  com-
pounds   comprising  ashes,  ether  extractable  substances,
polysaccharides, proteins, traces of pektins, poly phenols, and
dyes. The Hartel  turbidity test is  a  simple method for deter-
mining the effect of smoke on spruce and delineating the area
under attack. The test was analyzed in detail, its nature par-
tially elucidated, and another simple method worked out for
orientational determination of the effect of smoke on the as-
similation organs of spruce. This test is based on the different
degrees of extractability of tannides  from healthy needles and
from needles exposed to sulfur dioxide. The  test requires no
special laboratory equipment. (Author conclusions)

The  loss  due to unburnt gases is determined by analyzing flue
gases with a GKhP-3 or VTI-2 apparatus, or with chromato-
graphic or tit rime trie gas analyzers.  The choice of method is
governed by the required accuracy of determination as well as
by the minimum loss reliably recorded. Errors in determination
result from errors  in  gas  analysis, in calculating flue gas
volume, and in calculating the calorific value of the fuel. Ex-
pressions  are derived for calculating the errors of determina-
tion  for the different gas analyzers  and for establishing with
adequate reliability the recorded minimum value of the con-
centration of components under determination. Allowable er-
rors  of determination are also calculated for different types of
fuel. Based on a comparison of these values with the errors of
determination by the different methods, the preferred analyzer
for each type of fuel is determined. Use of a chromatograph is
recommended for anthracites and coals.

In the future, stack  gas  monitors for sulfur  dioxide  may be
require to  demonstrate  compliance  with  federal regulations,
and such monitors may become integrally associated with con-
trol systems such as scrubbers. For application in power plants
and  heat-generation  facilities,  a potential stack-gas  monitor
must be reliable and easily maintainable, reasonably accurate
and free  from errors due to contaminants,  and of simple con-
struction. The Gas sampling procedure  must be such that sul-
fur dioxide in the gas  under test is not altered  by sampling
conditions. A sulfur dioxide measuring instrument based  on  a
mercury   substitution  and   nucleonic detection   (MSND)
technique provides these four  desirable features. The instru-
ment is characterized by a stoichiometric substitution of  mer-
curv for sulfur dioxide in a reaction cell, transfer of the  mer-
cury to a measurement cell, and measurement of the mercury
by low-energy X-radiation absorption. Construction of the in-
strument is simple and the disposable reaction cell is charged
with reagents for 10-day  operation. Measurement accuracy is
excellent due to the stoichiometric substitution which is unaf-
fected by interfering substances. Since the mercury substitu-
tion occurs in an aqueous medium, the gas sample need not be
freed of water vapor and particulates. Total response time, as
determined by the sizes of reaction and measurement cells and
fluid flow rate, is approximatel 15 min.

An evaluation  of the colorimetric  methods of determining
chromium in  air and  urine based on the reaction of Cr(6+)
with  diphenylcarbazide was  carried  out, using radioisotope
techniques as the comparative method. Recovery of chromium
from  solid absorbers is not complete because of the reduction
of Cr(6+) to Cr(3+) and may be a source of errors in analysis.
It is recommended to do the washing-out with cold water and,
simultaneously, to carry  out the calibration of the  method
from  the moment of introduction to the absorbers the known
quantities of chromium. Oxidation of chromium  in urine sam-
ples occurs with the same yield, irrespective of the quantity of
chromium. The colorimetric method of chromium determina-
tion in urine  is of the same order as aqueous  solutions, and
therefore  is  suitable  to  the  hygienic investigations for  the

The  possibilities  of  using  bacteria-collecting equipment  for
estimating the bacterial seeding of atmospheric air at  various
air movement speed were examined and a device for precision
isokinetic aerosol sampling was developed. Results of studying
the effectiveness  of the bacteria-intercept devices at  various
air velocities in a wind tunnel are summarized in tabular form.
The  majority of  the  devices  were unsuited  to  isokinetic
sampling, since aerosol particles precipitated on the end-face
of the tunnels of the intake sections of the devices. This short-
coming is eliminated  in a sampler having tubes with cham-
bered edges, a clamping device for filters, and whose  capture
of aerosol particles is a function of the position of the inlet ap-
paratus in relation to  the direction of wind movement in  the
tunnel. Collection efficiencies  of the sampler  at various intake
positions for particles of different dispersities  are tabulated.

Results are presented of the number of microorganisms in 1 cu
m of air as determined, respectively, with the Krotov device
and by the the jar-cap method on different agar media. The
amount  of growing  colonies was  several  times  greater in
seedings  taken by the jar- cap method than with the Krotov
device.  Colonies  from the  air seedings obtained by  both
methods  grew least of all on simple  agar. When the jar cap
method and sugar agar were employed, the number of colonies
increased 1.5 to 6  times. The best results were obtained  on
agar with rabbit blood.

REACTION OF NITROGEN OXIDES WITH  AMMONIA AND
AMMONIUM HYDROXIDE.  Taiki Osen Kenkyu  (J. Japan
Soc.  Air  Pollution),  2(1):98-100,  1967.  Translated  from
Japanese. 8p.
The reaction  between nitrogen oxides and ammonia and am-
monium hydroxide was studied. The  validity of the equation
2NO2 plus 2NaOH yields NaNO2 plus NaNOS plus H2O was
confirmed by determining the NO2 and NO3 ions in solution.
It was also confirmed that NH4OH reacted  with NO2 as ex-
pressed   by  2NO2  plus  2NH4OH  yields  NH4NO2  plus
NH4NO3 plus  H2O.  However, gaseous NH3  reacted  with
NO2 as  shown by 2NO2 plus 2NH3 yields NH4NO3 plus N2
plus H2O. This reaction  was rapid and  exothermic and was
useful for the removal of NO2. Although NO did not directly
react with NaOH or NH3, its air oxidation in the presence of
NaOH or  NH3 proceeded  as follows: 2NO plus O  plus
2NaOH   yields  2NaNO2 plus H2O or 2NO plus O  plus
2NH4OH yields NH4NO2 plus N2 plus  3H2O.  In  this case,
reactions with NaOH and NH4OH produced different mols of
NO2 ion. On oxidizing the mixture of NO2 and NO in the air
and collecting it in alkali, if a NaOH solution was employed, 1
mol of NO2 produced 1/2 mol of NO2 ion and 1 mol of NO
produced 1 mol of NO2 ion. Thus it was impossible to deter-
mine the total quantity of NO2 plus NO unless one of the two
gases  was determined by using some other method.  However,
on collecting in an NH4OH solution, 1 mol  of either NO2 or
NO produced 1/2 mol of NO2 ion, so that twice the quantity
of NO2  ion was equal to the quantity of NO plus NO2. Based
on this experimental result, the NH4OH  solution was adopted
as the collecting solution for NO2 plus  NO in the standard
method  of determining NO and NO2 in flue gas described in
Japan Industrial Standards.

DEVELOPMENT OF A SIMPLE METHOD FOR MEASUR-

HOUSE FURNACE USING SOLD3 FUEL. (Entwicklung einer
einfachen  Methode  zur  Messung  der  Staub-,  RuB-  und

In order to measure emissions from coal furnaces outside the
laboratory, a simple, easy to operate measurement  method is
necessary. To  fill this  need, the  National  Institute  has
developed a procedure derived from  the filter paper method.
The sampling is done by an automatic measurement appartus.
In short time intervals, colored spots are put on filter paper
quasi-continuously Alterations in  the spots  characterize the
course of the burning and the amount of discharge. This in-
                        strument is an instrument customarily used to determine the
                        soot output of oil burners; it has been altered to suit the
                        present requirements. One provision for its use with coal fur-
                        naces was a shortening of the sampling period for each filter
                        spot by more  than 90%. The  filter spots obtained  in experi-
                        ments  with coal furnaces were,  however,  not only grey to
                        black colored,  but also had tones  of yellow to brown, as well
                        as mixtures. An evaluation of the filter spots by the com-
                        parison scale  for  oil burners was  not  possible.  On  these
                        grounds a two dimensional  comparison  scale was  developed
                        which  was built up from a soot  comparison scale  and a tar
                        comparison scale. It contains  not only  the pure colors, but
                        mixed  colors obtained in measurements. The whole  scale con-
                        sists of 120 by 20 mm comparison  fields.  Each comparison
                        field is ordered vertically and horizontally (letter and number).
                        Each comparison field corresponds with a count. All of the
                        filter spots are evaluated during  a burning period using the
                        comparison scales  by averaging  the corresponding  measure-
                        ment counts. The average emission values F (average concen-
                        tration in the exhaust gas during the smoke development
                        period) and E' (discharge related to the calories given off) can
                        be contained. Measurements on coal furnaces show that for
                        most practical cases the results  correspond to the emission
                        count  of house furnaces. This is shown through comparison
                        with other measurement methods. The experimental material
                        under consideration makes possible the determination of emis-
                        sion limits for house furnaces at this type. (Author summar

                        The deviation in measurement  of aprticle concentration due to
                        anisokinetic sampling is experimentally evaluated  for  solid-
                        liquid flow (water-glass beads two phases), where the necessa-
                        ry uniformly sized particles are easily available. The experi-
                        mental results are  numerically presented  and an  empirical
                        equition is proposed in whic the ratio of sampling to main flow
                        concentrations depends on the ratio of sampling to  main flow
                        velocities and an experimentally obtained gradient coefficient.
                        The results are also compared to previous experimental results
                        and  other semi-theoretical  formulae  for the  solid-gas  two-
                        phase  flow. It is evident that the  anisokinetic sampling errors
                        for solid-liquid flow are nearly half those for solid-gas flow,
                        and  that  Watson's equation  agrees fairly well with the results
                        of the  present  experiment. On  the other hand, the anisokinetic
                        sampling errors depend on which definition of mean particle
                        diameter is used for the inertial parameter.

CASCADE IMPACTOR.  (Nijigen kasukedo, inbakuta no bunri

33(12):1265-1271, Dec. 1970. 9 refs.
The separation mechanism of the two-dimensional cascade im-
pactor wa studied with a combination model of potential free
stream and stagnation flow. Like  the circular impactor, the
two-dimensional cascade  impactor has a slit nozzle; the latter
collects more particles, however, although separating them at
a slower rate.  In fluid flow, gas velocity  distribution depends
on the free stream line at a point distant from the center of the
collection plate; in stagnation flow, it depends on a point near
the center. With the model used, the trajectory of boundary
particles gives  the target collection efficiency and the effective
area of the collection plate. The same calculation for various
points of the nozzle leads to each point on the surface  of the
collection plate. From differential calculation of the measured
points the distribution of collected particles is obtained. Calcu-
lated target collection efficiency, collection area, and distribu-
tion  of collected particle  are  compared with experimental
results. In the  experiments, two  impactors were connected, the
first stage having the larger two- dimensional nozzle. Particles
collected  at each stage  were determined from microphoto-
graphs.

DETERMINATION.  J. Anal. Chem. USSR (English Transla-

The sensitivity threshold of  fluorimetric determinations is set
by two  independent values—the 'instrumental' and 'analytical'
sensitivity  thresholds. A method  is suggested  for computing
these values and assessing them experimentally. Based on the
application of the  method  to  fluorimetric determination of
basic  dyes, the sensitivity of a determination can be improved
by reducing the analytical threshold  through improvement of
the stages involved  in chemical  preparation of reagents. Equa-
tions  are given for  choosing optimum conditions for any re-
agent or for making a  comparison between reagents of the
same  type. In  general, the value of the analytical threshold is
approximately   proportional  to the  ratio of  the analytical
background and calibration factor. (Author abstract modified)

The electroconductivity analyzer for analysis of sulfur dioxide
was calibrated dynamically by standard low concentration of
sulfur dioxide to be generated from Teflon  permeation tubes.
The wWest-  Gaeke method too  was calibrated by the same
method. The  permeation tubes were placed in the calibration
apparatus, in which the temperature was controlled at 25 plus
or minus 0.1 C. Periodically the permeation tubes were rapidly
weighed  with a semimicro balance. The weight loss  of the
tubes  per minute was almost constant. The  average values of
the SO2 concentrations  measured by the electroconductivity
analyzer were reduced by  1.9-3.4% from the average  values
for the tube computed from the gravimetric data. Th average
values of the  SO2 concentrations measured by the West-Gaeke
method  were  reduced  by  1.3-4.0%  from the gravimetric
calibration for the tube. When the humidity was less than 20%,
the adsorptions of the new glassfiber filters for  SO2 (Gelman
A type)  were larger than any other fiber  papers. The  new
glassfiber filters adsorbed 22.4%  in 0.2 ppm of  the SO2  con-
centrations, but by using continuously, the adsorption of glass-
fiber filters was reduced gradually. The filter papers (Toyou-
roshi  No. 1)  adsorbed about 10% and Whatman No. 4 about
2% in 0.2 ppm of the SO2  concentration. The  adsorption of
new filter papers was almost the same as older filter papers.
Their adsorption rates were lower in the high  concentration
than in the low concentration in the case of three kinds of fil-
ters. When the  humidity was 60%, the adsorptions of the new
glassfiber filters, (Gelman  A  type) for SO2  were markedly
large. They adsorbed 60.4%  in 0.1 ppm of the SO2 concentra-
tion, 44.6% in 0.2 ppm and 27.2% in 0.5 ppm. The new Toyou-
roshi  No. 1 and Whatman  No. 4 adsorbed  about  10%. Their
adsorption rates were higher in high humidity than in low hu-
midity. The adsorption of Teflon pipes was lower than any
other kind of pipes. In low humidity, glass pipes adsorbed al-
most  the same  degree as Teflon pipes, but hi high humidity,
glass  adsorbed  15-24% of the  SO2 concentration. Teflon was
no influenced by humidity.  The  vinyl chloride  pipes did not
adsorb, but increased the measurement values The interfering
substances  with the measurement by the electroconductivity
analyzer were generated from the new vinyl chloride pipes.
The measurement values were higher than the real values, ac-
cording to a loss in quantity  of absorbing solution by babbling.
In the case of low humidity, low adsorbing solution, and abun-
dant air flow, this error was increased.

The process  of smoke-particle deposition on filter paper was
theoretically  analyzed. The theory  of probability was applied
to calculate the white area when a certain  amount of  carbon
particles had been  deposited on  the filter.  The  relation
between the meter reading and the white area percentage was
obtained and was employed to  derive a foimula giving the
amount of carbon from the meter reading. To check the validi-
ty of the theory, an experiment was conducted using a steady-
smoke generator  and photoelectric  color meter. Smoke was
produced by  the incomplete  burning of propane. A diagram of
the sampling  apparatus is shown, as is a sample  holder  design.
Six kinds of  filters were employed to catch the carbon parti-
cles. The thicker the filter, the more stable the light reflection.
The derived  formula  was valid. The carbon content  of the

combustion gas was quantitatively determined by the meter
reading if the carbon concentration on the filter was within a
certain range. Beyond this, the error increased rapidly. The ef-
fect of filter characteristics on the meter reading was incon-
siderable. The Bosch smoke meter was  chosen as a typical,
commercially available meter of the filter paper type. It was
checked  by the photoelectric  color  meter; correlation  was
satisfactory.

The disagreement between sulfur dioxide values obtained  with
an air pollution (AP) meter and the rosalinine method was stu-
died. A high-recision, large-scale standard gas generator and a
condenser-collector of polluted air were designed and built for
a microanalysis of pollutant components. The gas  generator
prepared SO2 concentrations of 0.05-0.20 ppm with an accura-
cy of 95%, or within the plus or minus  0.02 ppm confidence
range.  The sulfite  standard rosalinine method gave an  SO2
value 10% lower than the AP meter. Nitrogen oxides up to 0.2
ppm, carbon monoxide up to 40 ppm, and hydrochloric  acid
up to 0.2 ppm did not affect the AP reading. No differences in
AP values due to location were observed in field tests, nor did
the effect of atmospheric salt depend on locality. The effect of
salt on AP meter readings was about 0.01 ppm. No other com-
ponents of air affected meter values  except ammonia, which
lowered the value. It is  concluded that the higher SO2 value
measured with the AP meter is due to the loss of the absor-
bent in the meter.

NON-DISPERSIVE  INFRARED ANALYZER.   (Hibunsankei

(Electronic Sci.), 21(2):23-27, Feb. 1971. 5 refs.
The non-dispersive infrared analyzer was developed for indus-
trial applications but has  recently been widely used in the
quantitative analysis of automobile exhaust fumes  and indus-
trial waste gases.  It utilizes measurement of  the molecular
                        dipole moment to determine the amount of infrared energy ab-
                        sorbed by a gas sample. The use of such physical phenomena
                        provides rapid response, high selectivity,  and simple main-
                        tenance. Applications of the NDER analyzer include the deter-
                        mination of carbon monoxide and carbon dioxide in air; car-
                        bon monoxide, nigrogen oxides, and hydrocarbons in automo-
                        bile exhaust gases; and sulfur dioxide in stack gases. By com-
                        parison to the NDER, a dispersive-type infrared analyzer has a
                        complicated optical system and is  not effective for long-term
                        analysis. Two basic forms of the NDIR are the negative filter
                        type and positive filter type. The former has a nonselectiv de-
                        tector while the latter is selective with respect to specific wave
                        lengths  for specific sample gases. Brief discussion is provided
                        concerning the condenser microphone used as a detector for in
                        the positive filter NDIR. The noise elimination characteristics
                        of the two common amplifiers used are compared. Response
                        time of detectors are insignificant in contrast to the response
                        time of indicator devices. The linearity of output and the auto-
                        matic calibration circuitry are also discussed.

                        Design and performance data are reported for a nondispersive
                        photometer which permits the continuous  quantitative  deter-
                        mination of a sample gas. The instrument measures the ab-
                        sorption intensit of the sample gas in the vacuum ultraviolet
                        range and compares it to that of the reference gas (nitrogen).
                        The photometer has  an  evacuated optical system. The  ul-
                        traviolet light  from the light source (a deuterium discharge
                        lamp) is cut off by the combination of a concave grating and
                        exit slit, so only vacuum ultraviolet  light (165-20  nm) passes
                        through the gas cell. The transmitted light is made  visible by a
                        thin fluorescent  film and then detected by a photomultplier.
                        Performanc tests show that the photometer performs satisfac-
                        torily as a continuous analyzer and accurately determines  in-
                        flammable components in volatile gases. Allowable concentra-
                        tions or explosion limits of many gases can be detected by this
                        device, which has applications for safety control or process
                        control in  manufacturing.

                        A dispersive type infrared analyzer is discussed with reference
                        to  its photometric system, electronics for signal  processing,
                        and the introduction  of  infrared  absorption  spectrum. The
                        signal processing system differs according to the time-scale of
                        observed  or analyzed phenomena: the analysis stationary or
                        slowly  proceeding phenomena is  the subject  of  this  paper.
                        There are two essential types of monochromatic devices, and
                        others are variations of them: monochrometer is an indepen-
                        dent  device  dividing  an  infrared ray  into  its energy  or
                        wavelength, another is a detector with the ability  to  select
                        rays. The  analyzer operates to divide the infrared ray from the
                        light  source, by mirrors, into sample and reference ray bun-
                        dles.  After their absorption in corresponding cells, these are

sent alternatively to the monochrometer and are detected. The
differenc in light intensity at a certain wavelength causes  an
alternating  current  in the detector, the frequency of which is
determined by the revolutional speed of 2 perforated mirror
disk gating the absorbed rays. The alternating signals are em-
plified and rectified to be modulated  for a servo-motor. The
motor is connected to an optical attenuator controlled to give
the same intensity as each ray. The change of optical attenua-
tion is recorded to  give the absorption. A gas analyzer usually
has two light source and  not mirrors. The gas generally ex-
pands with the absorption of an infrared ray, and the change
of the gas  volume is measured as the change of capacitance.
The design of the pre-amplifier depends on the type of detec-
tor used. The pre-amplifier is essentially a noiseless amplifier
giving low impedance. The amplification of the main amplifier
is  40-80 dB, and the frequency band selected is  that of the
chopper  of absorbed  ray  for  cutting  off noise. Several
problems in the design of amplifiers and rectifiers are cited.
Two analyzers with different monochromatic devices are  com-
pared in terms of signal processing.

Sept. 1969. 3 refs.
A  chromatographic system is described that permits the  auto-
matic analysis of the complete composition of flue gases. The
system  uses one instrument  for  the analysis of combustible
components (hydrogen, carbon monoxide, and  methane) and
another for determining  incombustible  components (oxygen
and  carbon dioxide). Complete  separation of combustibles
takes place in one column filled with activated carbon. The
other instrument has one  detector but several  columns con-
nected in series, including  two filled with molecular sieves.  By
removing  nitrogen  from  the  system  the  molecular  sieve
columns reduce the analysis of incombustible components to
4-4.5 min. Under optimum  conditions,  the sensitivity threshold
of this instrument with respect to oxygen is 0.75%. The  other
instrument has a sensitivity of 0.008% for methane, 0.015% for
carbon monoxide, and 0.001% for hydrogen. Analysis requires
4.5 min. Both instruments performed satisfactorily when tested
under industrial conditions  at a power station.

REVIEW OF DIRECT  MEASUREMENT METHOD OF SUL-
FURIC ACID MIST IN ATMOSPHERE. (Taiki chu no ryusan
misuto no chokusetsu sokuteiho no kento). Text in Japanese.
Preprint, Japan Chemical  Society,  Tokyo, lp.,  1971. 1  ref.
(Presented  at  the Japan  Chemical  Society Annual  Meeting,
24th, Tokyo, March 1971, Paper 3406.)
The  establishment of a measurement method for sulfuric acid
mist, has been desired. So far, such methods as trapping  sul-
furic acid mist with filtering paper, measurement of the electri-
cal conductivity of  the liquid, or  diffusing, have  been re-
ported, but none a selective, accurate quantitative analysis, or
simple to handle. An attempt was made to trap the dust con-
taining sulfuric acid mist by dry impinger method. The method
adopted by Scaringelli  et al. was reviewed, and the  modified
method has been proposed.  After  dried nitrogen gas  is let
through fuming sulfuric acid, and is contacted with the  air,
with a certain  steam pressure,  the  sulfuric acid  mist is
generated. It is then let in the device connecting the dry imp-
inger and filter. The slide set under the  nozzle of the impinger
impacts and traps  sulfuric  acid mist The untrapped mist is
trapped by the filtering paper later. The trapping effectiveness
of the impinger was checked, by changing the nozzle diameter,
di, of  the impinger, distance between  nozzle and slide,  dis;
concentration of SO3, C; steam pressure, P; and  velocity, V.
As a result,  under the condition of di equals 0.25  cm, dis
equals  0.1 cm, C equals 3 ppm, P equals 1 Omm Hg,  V equals
10 1/min,  the  effectiveness was about 90%. Therefore,  this
method will do, as a simple trapping  method. A glass fiber
slide was  used but  a check is being made on copper plates.
The dust trapped contains metal sulfates, etc. Scaringelli et eL
heated it in nitrogen gas, and evaporated only sulfuric acid
mist separating it from  other dusts. Evaporated sulfur trioxide
was reduced by copper and measured as sulfur dioxide. How-
ever, no detailed report has been made as to the conditions of
manipulation,  so that in this  study, separation and reduction
temperatures  of sulfuric acid mist were checked. The device
consists of a quarz tube, with 3 cm inner diameter, 1 m long,
and 35 cm long separation  furnace  and 30 cm reduction fur-
nace which can be  heated  independently of each other. The
sample  enters the  separation furnace,  and sulfuric acid is
evaporated. Sulfur trioxide is generated and sent to the reduc-
tion furnace by nitrogen gas. Twenty mesh copper net, which
was hydroge reduced overnight  at 900 C was used. A certain
quantity of 103N sulfuric acid was taken by micro-syringe and
was  made  the standard sample.  Scaringelli et al. used  the
separation furnace at 400 C, but in this  study,  quantitative
analysis could be made at 200 C. Although Scaringelli repored
that the separation furnace was at 500 C. in this study, at 700
C, no reduction occurred, and at 800 C nearly complete reduc-
tion occurred.

TRIAL CONSTRUCTION OF NON-DISPERSION TYPE VISI-

NITROGEN  DIOXIDE,  CHLORINE,  AND  BROMINE.

(Analysis Instr.), 9(6):362-366, June 1971. 8 refs.
A trial  non-dispersive type  visible light  gas  analyzer for
process, quality, or safety control was built,  and it was applied
to the continuous measurement  of a two-component inorganic
gas mixture. The measurement principle was  that  the  dif-
ference  in relative absorption intensities  between  the sample
gas and the reference gas was  continuously recorded in the
visible  spectrum. Unlike conventional devices, the  analyzer
had no filter equipped with relatively long light path gas cells
(SO cm) for  high sensitivity. It was  composed  of a power
supply for the light source (tungstenO lamp), an optical system
(single  light  source, double  beam, and  single detector),  a
power supply for the detector  (photomultiplier) an amplifier
and  a  recorder; it  used  the  deflection method. The per-
formance test showed that the span drift (plus or minus 2%/12
hr), the influences  of ambient  temperature (1%  C), and the
source  voltage (plus or minus 2.5%/90-l 10V)  were somewhat
high. These were caused by the voltage drift of  the power
supply for the light  source which changes light source intensi-
ty. Several densities of two-component gas mixture samples
(determined by  the condensation-gasification  method)  were
prepared using  nitrogen as  a  balance  gas  (reference gas:
nitrogen).  The impurities in nitrogen  dioxide (nitrous oxide,
nitric oxide, and nitrogen tetroxide) hardly influenced the mea-
sured values. It took two or three minutes from the 0, 100 ad-
justment to the measurement. Beer s law held in low densities
(absorbance: 0-0.25), and for  higher  densities a  regression
quadratic  curve was estimated. The  limit  of detection was
0.005  vol%, and the  measuring range  was  0-1  vol% for
nitrogen dioxide. The influence of  the interference  gas was
hardly considered because few gases absorb visible light. This
method  may be  used to determine the analytical components
in a many-component gas mixture.

PARALLEL DETERMINATION OF NICKEL AND COBALT
IN URINE AND ATMOSPHERE. (Stanovenie nlklu a kobaltu
vedla seba v moci a v ovzdusi). Text in  Czech. Pracovni Lekar.

Ceskoslovenskom kongrese pracovneho  lekarstva s medzinarod-
nou ucastou v Usti nad Labem, June 4,  1969.)
A spectrophotometric  method  was used  to  determine the
amount of  nickel and cobalt  with 4-(2-pyridylazo) resorcin
(PAR) in urine and in the atmosphere. This method is based on
the formation of chelates and cobalt with PAR, with the ab-
                         sorption maximum at 487 and 500 nm respectively. The nickel
                         chelate is somewhat weaker than the cobalt chelate, and in the
                         presence of fluorides and Na2EDTA, it decomposes within 10
                         min at 100 C, while the cobalt chelate does not change. Ten
                         unexposed persons were  tested;  a mean  of 0.027  micron  g
                         Ni/ml and 0.023 micron g Co/ml was found  in urine. The ex-
                         posed workers (who were  employed at a nickel smelting plant)
                         had maximum nickel values in urine of 0.240 micron g/ml and
                         maximum cobalt values of 0.383 micron g/ml. The maximum
                         mean values in the atmosphere were 0.349  micron g Ni/1 air in
                         nickel  electrolysis  and 0.477 micron  g  Co/1  air in cobalt
                         production.

                         A method for the determination of mercury in air with the aid
                         of a light, portable device is described. The method is based
                         on the absorption of mercury in an ampoule containing a carri-
                         er impregnated with potassium permanganate solution acidified
                         with sulfuric acid. The absorption  of the mercury is quantita-
                         tive. In a subsequent step the mercury  is  extracted from the
                         ampoule and can then be determined by a  suitable wet chemi-
                         cal method. This method has been used for measurements in a
                         chloralkali mill. (Author summary modified)

                         The basic mechanism of a non-dispersion  infrared-type (N-
                         DIR)  gas analyzer and  the gas  sampling  system  for the
                         analyzer are introduced. Any gas  composed of different ele-
                         ments  such as  carbon monoxide, sulfur  dioxide, ammonia,
                         water,  methane, ethane,  ethylene,  acetylene,  or  benzene,
                         shows  its own specific pattern of infrared ray absorption in
                         the range of 2-15 micron. When a particular gas flows into the
                         beams  of infrared  rays,  the intensity of  infrared  rays  of
                         specific wavelength, having passed through the gas, changes
                         according to the density of the gas. The intensity of a specific
                         infrared ray is then detected by an infrared ray detector for
                         the measurement of the gas density. A positive-type NDIR
                         analyzer was used as an example to further describe the basic
                         construction  and mechanism of the  NDIR analyzer. The in-
                         frared ray beams from the light sources are interrupted inter-
                         mittently at an interval of 2-15 Hz by a rotary shutter, and go
                         through the measuring tank and comparison  tank to  reach the
                         detector. Nitrogen, or a similar gas, that does not absorb the
                         infrared ray is sealed in the comparison tank,  while the gas
                         constitutent to  be measured is sealed in the detector equipped
                         with a membrane condenser inside. The membrane  partitions
                         the interior of the detector into two and  intermits  the lights
                         from the measuring tank and comparison tank simultaneously.
                         The energy difference between the two lights is thus detected,
                         since the light coming through the  measuring tank has become
                         weak according to  density of the gas. When sampling gas for
                         the analyzer,  the gas  should be pretreated  before being fed
                         into the analyzer.  The sampling  process  usually consists of
                         sampling, removal of dust, separation of condensate, removal
                         of interference  substances, and pumping.  Although  some of
                         the SO2 is dissolved in the condensate water during the gas
                         sampling, the amount lost is theoretically negligible.

ANALYSIS  OF  NITROGEN  OXIDES  IN AUTO EXHAUST
GAS. (Jidosha haiki gasuchu no chisso sankabutsu bunsekiho
to sono mondaiten). Text in Japanese. Preprint, Japan Society
of Analytical Chemistry, Tokyo, 5p., 1971. (Presented at the
Nitrogen oxides  Conference, 3rd, Tokyo,  Japan,  Jan. 22,
1971.)
The  nitrogen oxides concentration in automobile-exhaust gas
changes  with  engine driving conditons.  The concentration
ranges from 10 to a few thousand ppm, and more than 95% of
it is nitric oxide; nitrogen dioxide is very rare. Infrared absorp-
tion analysis, ultraviolet absorption, mass spectrometric analy-
sis, and wet chemical analysis are  used to determine nitrogen
oxides in automobile exhaust. The first three are used for con-
tinuous  NO analysis. Its use with a nondispersion-type  ul-
traviolet analyzer allows the  continuous analysis of a system
containing  both  NO  and  NO2. The nondispersion-type  ul-
traviolet analyzer can be applied to the system to convert NO
into  NO2 both for continuous and  sampling  analysis.  Mass
spectrochemical  analysis is also  utilized for continuous nitric
oxide analysis. Phenol-disulfonic acid and Saltzman methods
are employed  in continuous wet chemical analyses.  Also, an
interference filter eliminates  the effects of interfering com-
ponents  of  coexistent substances in nondispersion infrared
analyses excluding that of water: the water must be eliminated
carefully with a desiccating agent. Drierite is  widely used as
the drying agent; however, the reaction converting  NO2 into
NO proceeds on  the bed of  the dryer. The regulation of ex-
haust has been changed from  the concentration standard to the
mass  standard, so the sampling  method does  not require the
swift  response needed in the continuous process.  However,
constant volume sampling requires  accurate analysis  since it is
applied  to a diluted sample. The conversion of NO to NO2 in
the sampling bag interrupts the NO2 analysis. The develop-
ment of Chemiluminescence method is expected.

soc., Inc., Philadelphia, Pa., 21p.
Measurement of the falling velocity of dust particles in gases
is an important method of determining the size of the particles.
Since Stokes law  corrected by  Cunningham  and Millikan  is
utilized  for  this purpose,  the validity of the  law  has been
checked  out experimentally for the  case  of  single  particles,
determining  mass, density, and falling  time independently of
each other and any law of resistance. A method of radioactive
counting has been employed.

An optical method of measuring concentrations of aerosols is
described, in which the amount of background light is reduced
considerably compared to a previous apparatus. Modifications
which have been made to the lenses and dark field shutters are
indicated. A battery  has been replaced by alternating current
to achieve as high a sensitivity as possible. Aerosol concentra-
tions  to concentrations  of three times 10 to  the  minus 12th
power g/liter can be measured accurately.

Aside from microphotographic determination, the particle size
distribution of dust for sizes less than 50 micron can be calcu-
lated  from the falling velocity of individual particle fractions.
The particle mixture which is to be  examined is suspended in a
suitable fluid and the progress of sedimentation with respect to
time is observed. Methods to minimize disruptions of sedimen-
tation and the  resulting errors are discussed.

When analyzing the  particle  size of mine dust, one  is faced
with the task of determining a broad rang of particle sizes and
a mixture of  materials, which  differ greatly  with respect to
their  weights and optical properties. Problems connected with
photographic methods of analyzing  particle size are discussed.
The  minimum exposure  time for  small particles  may cause
overexposure  in the  case of large particles. An apparatus is
described which consists of an ultramicroscope below which
there  is a sedimentation chamber, a light source, and a photo-
graphic assembly.

In obtaining  air samples,  constant and pre-calculated flow
velocities  can  be attained with  orifices of appropriate dimen-
sions  under certain conditions, in which cases the volume me-
ters or  flowmeters can  be dispensed with. After  a thorough
mathematical description of the principles of the dynamics of
gases, the test results were applied to commercially available
injection needles,  self-produced orifice  plates  made up  of
metal foil, as well as glass orifices. Injection needles can also
be used without calibration, if a measurement  error  of five
percent is considered. From determinations of the cross-sec-
tion, the flow  velocities  in metal foil orifice plates can be pre-
dicted with a  great deal of certainty, while glass orifices are
distinguished  by the fact  that, next  to their chemical and
mechanical resistance capabilities,  they come closest in flow
behavior to theory. How velocities from 0.15 to 1400/hr were
realized with the types  of orifices  studied. The scope of the
various  possibilities for use permits a resolution of practically
every type of air sampling problem.

A sulfur dioxide gas concentration measuring device was con-
structed using the SO2 characteristic of forming sulfuric acid
particles in reaction to  vapor. The device constituted a larger
tube with an inner tube lined with platinum wires and wound
by a coil heater. The SO2 gas/air mixture was emitted from
one end of the larger tube and sent through the inner tube,
heated to 400 C. The SO2 changed into SO3 and came into
contact with a near-saturated vaporized air at the end of the
inner  tube and formed sulfuric  acid particles The  particles
crossed a belt of light and were  amplified by a photoelectric
particle amplifier placed at a 90 deg angle; the strength of the
scattered light was  measured. The results depended on the
quantity of gas flow, air flow, the condition of platinum con-
tact, and the  size of the  device.  Under the same conditions,
the  accuracy of results was assured. The SO2 gas concentra-
tion and the strength of light scattering formed a linear rela-
tionship.

A SIMPLE INSTRUMENT FOR MEASURING DUST AND ITS
CALIBRATION.  Staub (Duesseldorf), vol. 52:715-728, 1957. 5
refs. Translated from German. Sanzare Assoc., Inc.,  Philadel-
phia, Pa., 20p.
A fully  automatic dust  measuring  instrument  is described
which operates by impaction and has photoelectric recording.
The air to be tested flows through the inlet pipe, into a rubber
tube,  through  the  nozzle at increase speed,  and  strikes a
recording drum  which has been covered with prepared paper.
The minute particles which  are contained in the air become
strongly accelerated and penetrate the prepared surface where
they remain adhered. Due to the rotation of the drum and a
lateral motion  of the nozzle, a strip  of  dust appears on the
paper and encircles the drum in  a spiral shape. The  intensity
of this strip of dust is a measure  of the amount of solid impu-
rities  in the air. Procedures  for using this technique both in-
and out-of-doors are described. Calibration of  the measuring
instrument is also discussed.

Dust measuring processes are reviewed, with special reference
to the coal mining industry. Filters, centrifugal separation, im-
pact sampling, thermal separation, and electrical separation are
discussed. Optical  (Tyndalloscop) mechanical,  electrical, and
acoustical measurement procedures are described. The charac-
terization of the specific surface of dust may be accomplished
by determining the flow-through  time of a certain quantity of
air through a layer of particles of defined thickness. Methods
also exist for the determination of the form factor, the devia-
tion from the spherical form.  Light and electron microscopy
measurements are  indicated, as  well as techniques  for sedi-

                        Methods of measuring particle concentrations in stack gases
                        are  discussed. The  selection of sampling locations is men-

                        Odors can  be measured by a human panel procedure or with
                        analytical apparatus; the former method is used primarily to
                        determine the intensity of an odor and/or kinds of odors, while
                        the  latter method is more often used for the analysis of sub-
                        stances giving a particular smell. Odorants which exist  in ex-
                        tremely small quantities can now be detected by gas chromato-
                        graphic analysis.  However, it is still difficult to correlate the
                        detected odorants and the unpleasant odor they are believed to
                        cause.  Various   olfactory   tests   are  cited.   Deodorizing

                        point, analyses  were made  of pollutants in the atmosphere,
                        pollutants  in the  absorbent solution of  the AP Meter,  and
                        problems involving proper use of the  measuring instrument.
                        The mass  spectrometric method,  having  no relationship with
                         the  AP Meter and Rosaniline methods, was used to detect pol-
                        lutant gases in the atmosphere, to  examine the reliability of
                         the  other  two methods, and to detect pollutants other than
                         SO2.  The low   temperature  concentration  method  using

analysis of the AP Meter  s  absorbent  solution  clarified its
component substances to determine if the atmospheric pollu-
tants could be transformed into electroconductive substances
when absorbed  by  the solution.  An  experimental  device
prepared a large quantity of accurate standard gas and deter-
mined the bias and variation errors  of the AP  Meter and
Rosaniline methods.  Following laboratory  experiments, field
tests were conducted. Generally, the values indicated by the
AP Meter were higher than those  indicated by the Rosaniline
method. This was not due to other pollutant gases,  but to
evaporation loss of the absorbent  solution.  This trend was
greater when temperature,  humidity,  and  SO2 density were
lower. Thus, the AP Meter tends to indicate values higher than
the actual value in winter, when temperature and humidity are
low. With corrections for these factors,  the AP Meter values
differ by  10% or  less from those  obtained by the Rosaniline
method. No gaseous pollutant  notably affected the AP Meter s
values. Nitrogen oxides  of a few  hundred ppb or less hardly
affected the AP Meter. When ammonia was present in  the at-
mosphere, AP Meter  values were on the negative side. Salt
caused an 0.01 ppm difference in the meter.

Several  lasers are now available which  can be tuned to any
wavelength in the infrared region.  Diode lasers are made of  a
lead-tin-tellerium  semiconductor  and,  depending upon the
amount of tin and lead present, the wavelength emitted can be
adjusted  between 6.5  and 32 micron. With the  exception of
nitric oxide and carbon monoxide  whose absorption bands do
not fall  within the appropriate wavelengths, such  diode lasers
can be used for the determination of air pollutants. The elec-
trons in a spin-flip Raman laser, which is tunable  between 2.5
and 16 micron, act as  scattering centers.  The nitric oxide con-
tent of an air sample in the range  of 0.1  to  10 ppm was deter-
mined with a spin-flip Raman laser. Measuring time was four
seconds.

Methods  for the  measurement of dust hi  the air  were com-
pared. The Hibernia  and Wabolu funnels were changed regu-
larly every 14  days.  The adhesive foils were changed every
seven days. The  Landesanstalt vessels were changed  in the
first three measuring periods every 14 days, and every seven
days in the fourth measuring period. The two concentration
measuring  apparatus were  used at  the  beginning  of  the
eleventh  measurement period. The filter of one was changed
every 14 days  and the filter of the other every seven days.
Rainwater apparatus  collected  the insoluble and soluble dust
particles  in the atmosphere. The quantity depends  on the
material of the funnel or collecting vessel. The adhesive foil
picked up the insoluble components of the dust. The foil dis-
plays greater  susceptibility to extreme weather phenomena
such as heavy  rain,  sleet,  and hail. They are advantageously
used where they  are set up in a confined area with a large
number of  measuring points. Dust  concentration counting
devices on a filter basis are dependent on  the position of the
collection filter. The horizontal  open position  must be pro-
tected against rain. It also stores sediments from the wind in
addition to the dust samples.

Lidar can  be  utilized  to  detect inversion  layers, mingled
layers, and the interface of sea and land breezes, volume dis-
tributions of suspended particulates, and dispersion  patterns of
high stack smokes. At present, ruby crystals  are used as ele-
ments causing oscillation. Ruby crystals are stable and durable
but have the disadvantage of yielding slow pulse repeats (once
in 5 sec). Faster pulse repeats and an energy output of a  cer-
tain degree are desirable.  One of more  recently developed
laser oscillation elements is YAG, a crystal  of  yttrium,  alu-
minum and garnet, which  creates a 1.06 micron wave  length
and a pulse repeat of approximately 1000 Hz. The wave length
1.06 micron presents a  problem  in photoelectric conversion,
which can be solved  if the  wave length can be changed to 0.53
micron by using certain crystals with nonlinear transmission of
light. This laser refraction is called SHG  (Second  Harmonics
Generation),  and some  of practical  crystals with excellent
SHG are KDP and BNN. For the time being, the combination
of SHG and YAG seems to be the best solution for air pollu-
tion lidar.

the characteristics of the microflora of the air can take three
directions: determination of the sanitary-indicative microorgan-
isms,  of the  presence  of pathogenic microorganisms,  (by
mycological analysis  of the aerosols) and of the  presence of

those  which specify the organic mercury compounds. A classi-
cal method of determining total mercury  content is the spec-

ples. The other methods are atomic  absorption and neutron ac-

acid is converted to selenious acid  by  heating with hydrochlo-

The effect of sulfur  dioxide on the determination of nitrogen
dioxide was  examined.  First, sulfur dioxide  solutions  of
 ••everal different concentrations  were added to  the nitrogen
                        dioxide solution, the rate of light absorption of which is 0.31S;
                        the light absorption rates were measured. The more concen-
                        trated the sulfur dioxide and the more time elapsed after the
                        mixing, the less was  the rate of absorption. When nitrogen
                        dioxide gas and sulfur dioxide gas are mixed at the ratio of

                        Acetone, benzene, or octane extracts of polynuclear aromatic
                        hydrocarbons  (PAH) in dusts at three  aluminum works were
                        separated by paper chromatography and analyzed by thin-layer
                        chromatography or fluorometric spectroscopy. The  following
                        PAH were determined in dusts deposited in ventilation pipes
                        during   the  manufacture  of electrolytic  aluminum:   20-

                        tively determined by cutting out chromatogram spots and elut-
                        ing them into a solution followed by fluorometric analysis. The

                        the three plants were  0.051, 0.039, and  0.042 mg,  respectively.
                        The  method is also  applicable to investigations of PAH in
                        gaseous discharges and effluents.

                        Sulfuric acid in air was determined by passing air (0.5-1 1/min)
                        through distilled water to which an 0.5% ammonium vanadate
                        solution was added. The vanadate solution reacted with H2S04
                        to form a yellow color whose intensity was a linear function of
                        H2S04 concentration  and was stable for longer than 10 days.
                        The sensitivity was 0.005 mg H2S04 in  5.5 ml  solution and the
                        average error was 9.3%.

                        The  determination  of aerosols by a Lundgren impactor has
                        been used to  obtain data on particle concentration as a func-
                        tion of particle size and components. This impactor, which has
                        been developed for the U. S. Public Health Service, is cylin-
                        drical with 4 steps  of collecting drums. Teflon film of 0.3 mm
                        thick coated with silicon grease DC 200 is used for collection.
                        According to  Lundgren, particle sizes  of 50% cut point at 4
                        cfm  flow velocity and 2 g/cu cm particle density, are 10,  3, 1
                        and 0.3 micron for 4  steps. The flow velocity can be changed
                        from 0.5 to 7  cfm; 24 hrs sampling at 5 cfm for 150 micro-
                        grams/cu m of air collects approximately 30 mg of particles.

DETECTION OF AIR POLLUTION BY LASER RADAR.

A method  to determine the distribution of sulfur dioxide, nitric
oxide, and carbon monoxide in the air by means of laser radar
utilizing resonance  dispersion  was developed  in order  to
replace the existing chemical method which requires a long
time for determination and does not allow remote measure-
ment. This laser  radar  utilizes pigment  laser which  allows
oscillation over whole wavelengths from violet to infrared by
using different kinds of pigments and selection of appropriate
wavelength through the use of prism and diffraction grating.
For sulfur dioxide, ethanol solution of rhodamine 6 G is used
to obtain laser beam with 100 kw of peak output and 100 n sec
of plus width. The signal receiver uses a multiplier correcting
signal strength,  analysis of pulse amplitude by comparison  of
electric potential, and time  measurement by clock pulse  to
determine  the concentration and the location of the gas in-
stantly.

LASER-LIDAR, WHAT CAN  IT REALLY  ACCOMPLISH?
(Laser-Lidar, was  kann es wirklich)? Text in German. Umwelt
(Duesseldorl), 2(l):40-43, Feb./March 1972. 5 refs.
The most important  task of  the light detection and ranging
system (lidar) apart from meteorological measurements is the
analysis of air pollutants. It is used for spotting polluters.  In
order to determine whether the  returning  signal  has been
produced by soot, aerosols, or inversion layers and in order to
determine  how  much of a smoke plume is  harmless  water
vapor and how much is pollutant, two laser beams are emitted
shortly after  each other. The frequency of one laser beam is
shifted by temperature regulation of the ruby to the absorption
band of hydrogen. Water vapor absorbs this laser beam more
than the other. The difference of the two signals is a measure
of the water vapor fraction. For qualitative  and quantitative
analysis of the gaseous components,  the Raman effect is used.
Since the  quantum yield of the Raman laser is so low, the
measurement of concentrations which represent the tolerance
limit for man is not feasible. The simplest version of the laser-
lidar comprises a laser as transmitter and a receiver with a
photodiode or  multiplier and  a recording unit.  For simple
distance measurements up to about 10 km a pulse power of 5
to 10 MW suffices. Maximum pulse powers of 100 MW at a
beam diameter of 10 mm are now achievable.

A short time collection method by a high volume air sampler
was  compared  with a long  term collection  method by low
volume sampler in order to find a better method to determine
metal content in air- borne dust and to establish pollution pat-
terns in an area. Samples were collected for 30 days; 24 hour
collection by low  volume sampler and 10  day collection  by
high volume sampler were performed.  Filter papers on which
samples were taken, were ashed in low temperature and un-
derwent  several acid treatments  to produce sample solution,
which were analyzed by means of  atomic absorption spec-
trophotometry for cadmium,  lead, manganese,  and copper.
Using the average values of  10 days for samples obtained  by
the high volume samplers, the amount of dust collected was
higher in the samples  by  the high volume sampler. However,
the concentration percentage of metals to the amount of dust
was  higher with the low volume sampler.

Size distribution of dust and heavy metals in the air was deter-
mined by means of an Andersen sampler. The sample was col-
lected at a velocity of 1 cfm for 3 to 7 days from March to
July, 1971, into separators with  8 steps. Size distribution  of
dust was determined by weighing. Metals, expecially lead, cad-
mium, and copper were determined by atomic absorption spec-
troscopy after treating the sample with acid. Size distribution
of both dust and heavy metals  showed a logarithmic  normal
distribution. Respirable dust (less than 3.3 micron) ranged from
50 to 70%, and the heavy metals occupied approximately 70 to
80% of the respirable dust.

The FKS type low-volume air sampler as a collection device
for air-borne particulates was examined. The amount collected
by-this sampler was compared with that collected by a filter-
holder  type-C  to find a relationship  between them.  When
several of these samplers were used at the same time, varia-

value of dust varied from 2.6 to 5.4%. Using this sampler, total
dust and metals, such as iron, copper, manganese, and lead in
the dust were determined at several points in Amagasaki-city.

                        (selected as the standard  estimation method  for particulate

                        methods were compared. The estimation was made continu-
                        ously in Tokyo, Osaka, Ichihara, and Kobe. From the data ob-
                        tained, the correlation between the particulate  weight concen-
                        tration and the  number of  counts in light scattering methods,
                        and  between particulate weight  concentration, transmittance,
                        and  reflectance of the filter tape air sampler was calculated.
                        Transmittance was expressed by Log I/Io, where  lo stands for
                        incident light and I for transmittant light. Reflectance was cal-
                        culated from the (Xo - X)/(Xo -  D) formula, where Xo stands
                        for the reflectance of the filter  that does not  collect particu-
                        lates and D stands for the reflectance of standard black filter.
                        From the above comparison, it was clear that the best was the
                        correlation between the number of counts by the light scatter-
                        ing method and particulate weight concentration, followed by
                        correlation between transmittance through a filter of a tape air
                        sampler and the  particulate  weight concentration, and the
                        worst was the correlation between the reflectance of the filter
                        of a tape air sampler and the particulate weight concentration.

CURY AS  A CATALYZER.  Gigiena i  Sanit.  28, (12)  73-6,

Mercury  vapor was found in the air  of production rooms of
the chemopharmaceutical industry producing synthetic drugs,
and  of the chemical industry producing  technical  organic
synthetic substances. The presence of mercury vapor was not
limited to the air of work rooms in which metallic mercury or
its compounds  have been used as catalyzers, but also in the air
of rooms assigned to the processing successive production
phases, as a carry-over by the reaction mass, or by the inter-
mediary half-products. In making sanitary evaluations of such
plants  this  fact should be taken into  consideration; it should
also  play an important part in making sanitary insepctions of
industrial production plants  in which mercury and its  com-
pounds are used as catalyzers. Mercury desorption from walls,
ceiling, surfaces  of equipment,  etc. should  be regarded as a
significant factor in air contamination with  mercury vapor in
processing  rooms of such production industries. Coating all
surfaces, including those of equipment, with a mercury vapor
nonpermcable  varnish  or paint will markedly  reduce  the
amount of  adsorbed  and permeated mercury vapor, the con-
centrations of  which will be  still further reduced by  the  in-
troduction  of  demercurization of the working premises. In
plan-  ning new,  or reconstructing and renovating previously
existing industrial premises of the type under consideration,
the location of technological  processes should be  arranged so
as to  reduce to a minimum air pollution with mercury vapor.
Manual operations   should  be  automated.  All  production
processes which used mercuric compounds as catalyzers, and
all associated production states, must be evaluated from the
sanitary hygienic viewpoint as industries which employ mercu-
ry and which must comply with corresponding sanitary specifi-
cations. (Author conclusions)

Ind. Health, (Tokyo) 8, (6) 19-28, June 1966. Jap.
A survey of the working environment in plants handling man-
ganese compounds was carried out in Osaka from December,
1963 to January,  1964. An  analysis  of the  air in  the plants
showed manganese concentrations of 2.3  to  17.1  mg/cu m
(median 8.4 mg/cu m) in the areas where maganese ore was
ground, 3.8 to 8.1  mg/ cu m  (median 4.9 mg/cu m) where elec-
trodes were manufactured,  1.9 to 21.1 mg/cu m (median 4.3
mg/cu m) where dry cell batteries were manufactured. An ex-
amination  of 134  workers revealed 4 showing clear signs of
disorders of the central nervous system indicating manganese
poisoning. Slight neurological symptoms were found in 11 of
47 workers grinding manganese ore, 4 of 32 workers manufac-
turing electrodes,  and 7 of 55 workers manufacturing dry  cell
batteries. No significant findings were seen in blood and urine
examinations. It was recommended that processes and equip-
ment in the plants be improved, periodic medical and environ-
mental examinations be strictly enforced, early detection of ill-
ness and adequate treatment be given, and a health education
program be initiated. (Athors' summary, modified)

Various aspects of the problem of dust in the air, its origin, ef-
fects  and  measurement are reviewed. Among the natural
sources, forest fires and volcanic eruptions are  mentioned.
More important are manmade dusts  deriving mostly from all
kinds of combustion. The effects of  dust on all forms of  life
are not completely known. Some occupational diseases like sil-
icosis and  other harmful effects of dust are  described. The re-
tention of particles of various sizes in the lungs is discussed.
Results  of  large-scale  health  examinations in Prague  are
quoted.  A section is devoted to particle size distributions and a
typical example is quoted. Problems and methods of dust con-
centration measurements are discussed in detail. A large list of
measuring equipment is given, both from  Europe and  the
USA. In each case the principle of operation is noted and re-
marks pertaining to their practical use are added. Another sec-
tion deals  with the problem of how  dust concentrations  are
correlated  with dust  fall measurements. Functional relation-
ships between the two quantities, obtained experimentally, are
plotted in several graphs and discussed in detail. Both concen-
tration measurements and dust  fall measurements bear a cer-
tain amount of statistical uncertainty. This, however, is  not
too objectionable since the effects of dust on humans can be
classified only in three to five  degrees at best. The article is
concluded by 82 bibliographic references.

A review of well-known air pollution episodes is given citing
environmental conditions, damages, and causes for episodes in
Meuse (Belgium)  in  1930, Donora, Pa.  in  1948, London in
1952, Mexico in 1950, Yokohama (Japan) in 1946, and Los An-
geles at present.  The  present problems  of air  pollution in
Tokyo are dealt with including  dust fall, SO2 concentration,
floating soot, dust, and hydrocarbons. The average  value of
dust fall was 23.46 tons/sq km/30 days for  1959 to 1963; the
soluble elements of soot fall were measured at 6.47 tons/sq
km/30  days. The  maximum  was recorded in 1961;  seasonal
measurements   indicate  a  maximum in  February  and  a
minimum in  December. Yearly variations of  the quantities of
coal and petroleum used between 1955  and  1964 indicate a
relation between dust fall and the amount of coal used, but no
relation between the  latter and petroleum consumption. The
distribution of SO2 gas  concentrations in  1964 as measured by
the  lead  peroxide method is  shown  on a  map  of Tokyo.
Hydrocarbon concentration of C2 to  C8 compounds ranges
from 15 ppb to 1.5 ppm. In heavily trafficked areas the con-
centration  of 3,4-benzopyrene is between 1.3 and 6.6 micro-
gram/ 100  cu m. The effects of automobile exhaust from the
gasoline engine are detected as high as 500 m. Also, water pol-
lution from the Samida river causes ammonia and hydrogen
sulfide to be discharged into the air.

AIR POLLUTION BY CARBON MONOXIDE. ((La polucion
del  aire por oxido de  carbono.)) Text in Spanish. Anales Med.
Cir. (Barcelona), 52(l):58-77, Jan. 1966.
In addition to a comprehensive review on the physiological ef-
fects and significance of CO pollution, the entire field of air
pollution is reviewed. Data are given on  the  amounts of vari-
ous pollutants and their effects on health and the economy.
The  amounts of pollutants discharged annually into the air in
the   City of  Barcelona are:  600,000  tons  of water  vapor,
850,000 tons of CO2, 80,000 tons of CO and 35,000 tons of
SO2. Snow which  fell in 1962 and in 1965 indicated that the air
over Barcelona in 24 hours  contained between 390 and 580
tons of dust, 6  tons of nitrogen oxides, and  19.5 tons of SO2
and SO3. The average and maximum values of carbon monox-
ide  in various cities are presented and in London range from
an average of 1.8 ppm to a  maximum during a smog of 200
ppm. In garages the  concentration may  be  as high as 1.250
ppm and concentrations of 200  ppm are not uncommon. The
various methods for measuring CO are outlined and control is
discussed.

                        As an example of the relationship between the number of
                        cases of pneumoconiosis and the level of contamination of the
                        air with dust, a'study was conducted on the health of  sand
                        blasters in the USSR during the years 1947-1950. Working con-
                        ditions  at different plants varied sharply, depending on the
                        volume of work, the dimensions of the casting the arrange-
                        ment and  state of the sandblasting chambers, and on the mea-
                        sures taken for individual protection. Only the composition of
                        the dust inhaled by the workers, which contained 85- 90 per-
                        cent quartz particles remained the same. Parallel investigations
                        enable us  to affirm that the mass of the active dust establishes
                        the level of the index of  the number of cases of morbidity.
                        The significance of the mass of the affecting dust was demon-
                        strated in  a specially conducted experimental work. Two series
                        of experiments were set up with white rats  into which quartz
                        dust of various dispersity was introduced intratracheally. Con-
                        sequently  it was affirmed  that the especially active  and  dan-
                        gerous quartz dust, with a particle size of less than .5 microns,
                        did not cause the development of silicosis because the mass of
                        the acting dust was insignificant. The experiements performed
                        indicate the predominant significance of the mass of the acting
                        dust, and  especially the mass of the most finely divided dust.
                        Here it is interesting to note that quartz dust consisting of
                        several size fractions caused the development of a silicosis
                        similar to the silicoses caused by  the action of dust of higher
                        fractions.  Consequently it  can be  stated that in the multifrac-
                        tion dust the mass of fine particles was insignificant, since this
                        dust fraction did not affect the character of the development
                        of silicosis. Thus it is evident that the origination of silicosis is
                        caused by the mass of the acting dust as well as by its fine-
                        ness. At the present time,  microscopic methods are still being
                        used for the evaluation of the degree of dispersion of dust, but
                        it must be borne in mind that the data obtained express the
                        degree of dispersion with respect to the number of particles of
                        various sizes, and not with respect to their mass.

                        levels are noted in areas overlooking the port, a fact attributed
                        to the presence of wastes from ships and sewers.

Dustfall was determined using the English deposit gauge, SO2
levels  determined  using the  lead  peroxide methods,  and
meteorological conditions noted  during  1962-1964. Data are
tabulated. Results confirm conclusions made previously, that
air pollution is not heavy, with the exception of limited areas
with rather heavy Participate levels.  Vertical atmospheric dif-
fusion in the Palermo area is good, while horizontal diffusion
is less efficient. The Palermo weather basin, being surrounded
by a semicircular mountainous ring, is equally polluted hi all
areas. Thus, industry should be  prohibited within the basin,
and the number of central heating units should be increased.

ON THE ATMOSPHERIC DUST AND SMOKE IN INDUSTRI-
AL CITY.  Text in Japanese. Kuki Seijo (Japan. Air Cleaning
Assoc.) (Tokyo), 5(6):13-19,1968. 5 refs.
The author obtained and studied  data on the particle size dis-
tribution, specific gravity, and chemical composition of the at-
mospheric dust in the Uokohama/Kawasaki industry area. Two
types of dust were encountered: one is 'fall' dust consisting of
larger particles (expressed in t/sq km/month) and another type
is 'suspended* dust consisting of  small particles (expressed  in
mg/cu m. The average quantity per month of fall dust in major
Japanese cities is tabulated. The  specific gravity of insoluble
components, based on the author's collection (by deposit gage)
in  the  Kawasaki/Yokohama area, averages 2.2S to 2.64. The
specific gravity in an  industrial area  tends to  be  higher.
Seasonal changes  are insignificant.  The  measurement of in-
soluble elements in the  fall dust  in Kawasaki showed  a wide
range of particle size distribution  with a median of 8.4 micron.
Other areas showed median diameters of 4.4-9.0 micron. Fall
dust in a non-industrial zone seemed to contain larger particles
than dust from  an industrial zone. Fall dust from both re-
sidential  and  industrial sources contains  larger particles;
removal or reduction thus seems  possible. The chief chemical
components in the fall dust were  SiO2, Fe2O3,  aad SO4.
When rainfall is high, SO4 level  is also high.  Suspended dust
particles  have an  average radius of 0.07S micron, and are
mainly soot from incomplete combustion or metallic  acid
fumes. Microscopic study revealed fine particles (mostly less
than 1 micron) of complex shape. This dust contains numerous
components, with SO4 prevailing. The degree of SO4 concen-
tration in the suspended dust is in direct proportion to the SO2
concentration in the  atmosphere. This point deserves  further
investigation.

CONTINUOUS  OZONE MEASUREMENTS IN A  HEAVILY
TRAVELLED STREET. (Kontinuierliche Ozon-Messungen in
einer verkehrsreichen  Strasse). Text  in  German.  Gesundh.
Ingr., 89(5): 144-147, 1968. 12 refs.
At two  measuring stations in Berlin, continuous ozone  mea-
surements were taken from the summer of 1966 to the summer
of 1967. The first measuring station was  located  in  a  busy
street in Berlin Steglitz. The air samples were taken at  20 m
and sometimes also at 2 m. The second station was in a  quiet
area without traffic; the samples were taken at 10 m. The
results show that in the busy Schlosstrasse, maximum ozone
concentration was about 5 pphm.  Of the total number of in-
dividual measurements, 8.6%  exceeded 1 pphm and only  2%
exceeded 2 pphm. The  maximum daily average was  3.2 pphm.
Higher ozone concentrations were measured in summer than
in winter. The average ozone concentrations in the traffic-free
area were much higher than  those in the  busy  street.  Com-
parison  of the diurnal variations of ozone concentration at the
two stations clearly shows the influence of traffic. In the traf-
fic-free  area, the ozone concentration  rises from a  maximum
between 5 and 6 a.m. to a maximum between 2 and 3 p.m. and
gradually subsides again. In the busy Schlosstrasse,  the ozone
concentration drops to a minimum between 7 and 8 a.m. At
this  time, which coincides with the morning  rush  hour,  the
ozone concentration was just half as high as that in  the traffic-
free area.

Air pollution in Madrid was  studied in 1967. Samples  were
taken from three different zones in the city; zones of heavy
urban traffic, zones of high  industrial concentration, and re-
sidential and garden zones. The results showed a marked in-
crease in air pollution over previous years. The amount of sul-
fur dioxide found was  100% higher than in 1966; the number
of days with concentrations of SO2 over 200 microgram/1 also
increased. On  certain days, SO2 concentrations of 0.6 micro-
gram/1 were exceeded. Smoke load was assessed  during  the
last  months of  1967.  Values  were higher than 300 micro-
grams/I.  Carbon  monoxide average concentrations were 11
ppm, but exceeded 100 ppm at peak hours. The concentration
of nitrogen oxides remained  unchanged, however,  they  were
higher in winter. The sedimentary dust average per year was
278 mg/sq m/day. This was described  as remarkable and was
greater  than the dust contamination  in  Paris during  1966.

First-year operation of a sulfur dioxide concentration monitor-
ing network covering a  5000  sq km area is  described and
findings are reported. Some 5000 measuring stations were in-
volved and were distributed at 1-km intervals in a rectangular
coordinate array with certain variations for practical reasons.
Twenty-six measurements were made at  each station during
the year. Sampling sequences  and data processing procedures
are explained.  Results of this  study  are  tabulated and maps
showing SO2 emission parameters are presented.

In 1958-59,  the Public  Health Service  and  the  School  of
Medicine of Vanderbilt University conducted a study in Nash-
ville, Tennessee, to investigate possible relationships between
air pollution and health and to obtain information on a number
of the engineering and meteorologic phases of air pollution.
Sulfur dioxide  was studied intensively, from a detailed emis-
sion inventory to ambient air measurements using several sam-
pling techniques. Seasonal Source strength and ambient levels
of SO2 reported in terms  of sulfation, using lead peroxide can-
dles, are discussed as a  function  of  radial distance from the
center of Nashville. A simple mathematical model is presented
to relate the emission pattern to the resulting sulfation pattern.

HYDROGEN SULFIDE DETERMINATION IN  AIR  WITH
AUTOMATIC SAMPLING.  (Schwefelwasserstoff-Bestimmung
in Luft  mit automatischer  Probenahme.)  Text  in  German.
Wasser Luft Betrieb, 12(9):529- 531, Sept. 1968. 9 refs.
A simple procedure is described for H2S determination based
on photometric measurement of methylene blue formed in the
reaction  of H2S  with dimethyl-p-phenylenediamine  in  the
presence of Fe(III) chloride. Samples of atmospheric  air are
passed through  an alkaline cadmium  hydroxide  suspension
which blinds the H2S present as cadmium sulfide. Its  useful-
ness for determination of the H2S content of contaminated air
can be enhanced by automatic sampling with the aid of a com-
mercially available control device  with  12 standard impingers.
However, the following conditions must be met: (1) the cadmi-
um hydroxide suspension in the  impingers must be  freshly
prepared in order  to maintain its absorption capacity  for at
least 24 hrs; (2) the cadmium sulfide suspension formed upon
sampling must remain  stable for at least 24 hrs; and  (3) the
volume of the air sample must be measured with sufficient ac-
curacy. Tests designed  to find out whether these requirements
can be met gave positive results. In addition, tests  to deter-
mine  the cross-sensitivity of the  H2S  determination to SO2
and  NO2 showed  that  it is not perceptibly affected  by the
presence of 1 ing/cum of SO2 or NO2 in the air sample. How-
ever, in the presence of these quantities of SO2 and NO2, the
cadmium sulfide content of the absorption suspensions was
lowered by about 20%. This effect could be leiminated by ad-
ding 5 ml of a 1.2% solution of ammonium amidosulfonate to
400 ml of the alkaline cadmium hydroxide suspension.

                         last three pollutants, samples were obtained by hanging white
                         cotton  cloths under the  eaves  for  30  days. After  exposure,
                         dust fall  was determined by reflectance, and ammonia and
                         chloride ion were determined by analysis  of the distilled water
                         used to wash the cloth. Average temperature  tended to be
                         higher at the 15th floor in any season. Sulfur oxides were most
                         concentrated at the 2nd floor (0.64-0.73 mg/100 sq cm/day) and
                         were highest in winter and fall. Dust fall was greatest in winter
                         on the  9th floor level. Ammonia was highest in the summer,
                         1.57 mg/30 days/400 sq cm. Chloride ion was also most con-
                         centrated in summer (2.27 mg/30 days/400 sq m). Air pollutants
                         were generally more concentrated at the  middle floors of the
                         apartment building.

                         underground tanks and pipes. The average chlorine content at
                         low tides  at the measuring station  of the Horingerdijk reser-
                         voir was 139 mg/1, 7 mg/1 lower than in 1967. The level of air
                         pollution during 1968 was more  or less constant in comparison
                         with 1967. A  study of the  1218 bronchitis complaints of male
                         civil servants indicated that bronchitis  occurs with increasing
                         frequency in the age group above 40 and especially above 60.
                         A study of chronic bronchitis and asthma  in elementary school
                         children in two sections of Rotterdam indicated  that in Cross-
                         wijk, 5.5% of 455  children had chronic  bronchitis  and 2.2%
                         had asthma. In Hillegersberg, 1.0% of 480 children had chronic
                         bronchitis and 1.7% had asthma. Measurements of precipita-
                         tion, smoke, polycyclic hydrocarbons,  CO, ozone, NO2, and
                         sulfur oxides  are presented. The smoke meter results show a
                         usual smoke content of 100 micrograms/cu m or more during
                         long periods of mist which  occur during the winter months. In
                         the  first  and fourth  quarters, the polycyclic  hydrocarbon
                         values  were much smaller than  those of 1964. Of 174 samples

one sample was higher than 30 ppm. The highest lead content
was  1.5 micrograms/ cu m. Ozone content of the air was less
than 20 micrograms/cu m on cloudy days. Nitrogen oxide con-
centration ranged from 100- 150 microgranis/cu m. Ninety-one
days were recorded with SO2 content equal to or greater than
350 micrograms/cu m, and 89 days were recorded  with smoke
content equal to  or greater than  250  micrograms/cu m. The
declining tendency for smoke pollution was attributed to the
increasing use of natural gas.

DETERMINING   AIR POLLUTANT  EMISSIONS   FROM
TRANSPORTATION SYSTEMS.   Preprint, Association for
Computing  Machinery, New York, N. Y., 22p., 1969. 18 refs.,
(Presented at the Association for Computing Machinery, Sym-
posium  on The Applications of Computers to the Problems of
an Urban Society, New York, Oct. 24,  1969.)
Internal combustion vehicles  are  a  source of  five major air
pollutants:  carbon monoxide, hydrocarbons, nitrogen oxides,
particulates, and sulfur oxides. Because vehicular pollution is
essentially  a  problem of  urbanization,  analysis of its source
must  be carried out  on  a metropolitan or smaller scale. A
method is presented for estimating the quantity and spatial dis-
tribution of motor  vehicle emissions  in a metropolitan area
from  established speed-emission relationships and transporta-
tion  study  data. On-the-road sampling of exhaust emissions
from  a representative sample of automobiles indicates there is
a consistent relationship between average route speed and the
quantity of  carbon  monoxide  and  hydrocarbons  emitted.
Metropolitan  transportation study agencies developed detailed
descriptions of future street and highway networks. The  Seat-
tle, Washington, metropolitan area was selected for the initial
application  of the vehicle emission estimation method because
of the transportation characteristics of the  area and the nature
of the transportation study data available. Emissions are calcu-
lated  for two 1985 street and highway networks, one based on
the land use pattern predicted if existing trends within the re-
gion continue, and one  based on a pattern which will  exist
only if certain development policies are implemented. The cal-
culated  vehicular emissions and estimated emissions from non-
vehicular sources can be  used with a meteorological diffusion
model to predict future air quality. (Author abstract modified)

DETERMINATION AND OCCURRENCE  OF  SMALL CON-

Prakt. Chem. (Vienna), 19(3):78-79, March 1968. 7 refs.
A new method for the analysis  of low N2O concentrations is
briefly outlined. The method is a form of gas-liquids-chro-
matography  (GLC)  with  separating  columns  made  of
propylenecarbonate- glutaronitrile on Sterchamol. With the aid
of a hot wire detector, 50 ppm N2O in 10  ml gas samples can
still be determined with accuracy. Using this method, the for-
mation of N2O was studied at the combustion of NH3-air mix-
tures  over  platinum- rhodium and the  N2O concentration in
the waste gases from nitric acid scrubbers was  determined.
Concentrations of 400 to 900 ppm N2O  were found in the
combustion gases, and of about 200 ppm  in the waste gases
before it was blown into the air. To adjust the GLC method to
the determination of low N2O concentrations (e.g. 0.2 ppm), a
concentration method was devised in which a concentration
column filled with silica gel was activated at 160 C, making it
possible to determine the concentrations usually found in the
atmosphere. Analysis performed with this method in the vicini-
ty of Linz  (Austria)  showed concentrations of 0.23  plus or
minus 0.04 ppm. The N2O concentrations in various rivers and
in drinking water were also determined. The apparatus is illus-
trated and a step-by-step account of the procedure is given.

Factors affecting  emissions  are  considered,  together  with
trends in  emissions  in the  Netherlands and Rotterdam. The
qualitative and quantitative  significance of air pollutants as
potential disease agents in Rotterdam is evaluated. The max-
imum sulfur dioxide concentration  so far recorded in Rotter-
dam is 1600 micron cu m; the maximum smoke concentration,
500 micron/cu m. No epidemiological  significance is attributed
to measured concentrations of fluorides, nitrogen, dioxide, car-
bon monoxide,  or lead. Concern is shown for the role of benz-
pyrene and other carcinogens in the  etiology of lung cancer.
Distinctions are made between acute, sub-acute,  and chronic
air pollution. During acute air pollution, SO2 and smoke con-
centrations in Rotterdam show five- fold increases. Sub-acute
pollution  occurs  when wind speeds  drop below 2  m/sec.
Chronic air pollution is present on all other days, especially in
winter. Though the effects of pollution can also be  categorized
as chronic,  acute, and sub-acute, the  level of air  pollution is
still  too  weak  to  cause illness. Methodologies employed  in
determining the relationship  between  air pollution  and human
mortality   and  morbidity  are  reviewed, and   hypotheses
developed to describe the effects of pollution  on illness and
death in  Rotterdam.  Refinements  in  analytical methods  are
urged so  that the  factors influencing increased chronic  non-
specific lung disease mortality and lung cancer mortality can
be identified. It is also  suggested that emission standards be
supplemented by regulations malting  it  possible  to restrict
emissions when meteorological data  and monitoring  station
readings point to certain dangers.

After extensive preliminary studies of the emissions and of the
atmospheric pollutant concentrations in the vicinity of an iron-
ore roasting plant, six sites  with comparable climatic growth
conditions and staggered  air pollution concentrations were
selected to  test the  injurious effects of SO2  on rye, wheat,
barley, rap, potatoes, alfalfa, clover, or tomatoes, etc. as well
as on oaks, beeches, spruces, pines, firs, and on cherry, apple
and plum  trees. Five stations were within the range of the SO2

emission source, while the sixth (control) station was outside
the area.  All plants and trees were grown in wooden con-
tainers to assure  the  same soil conditions. The SO2 content
was  measured continuously  during 1959-61. Criteria for inju-
ries to forest trees were the number of shoots and the amount
of circumferential growth; criteria for fruit trees and field and
garden crops were fruit quality and the yield. The reactions
observed on all plants are presented in the form of tables and
graphs. A differentiation is made between actual injuries, inju-
ries probably caused  by air pollution,  and possible injuries.
The highest value at which no symptoms were observed and
the threshold value to visibly harmful SO2 were determined. It
was found that barley, summer wheat, summer rap, tomatoes
and beets could by grown at  average  SO2 concentration of
0.59 ppm (0.141 ppm during the measured period), but not fruit
trees, forest trees, alfalfa, clover, spinach or  winter rye, etc.
Fruit  trees began to grow at  SO2 average concentrations of
0.26 ppm. Spinach was most sensitive to SO2.

SARAJEVO.  (Aerozagadenje i hronicni bronhitis u sarajevu).
Text in Croatian. Med. Arhiv.,  22(l-2):31-43, 1968.14 refs.
The  degree of air  pollution and the  prevalence of chronic
bronchitis in Sarajevo was determined. Measurements of sul-
fur dioxide and fumes at three locations showed that there was
a high degree of pollution in the center of the town. The peak
concentration was in January and the lowest was in July. The
prevalence of bronchitis  was determined  with questionnaires.
Two groups of  the population were included, the first being in
the polluted part of town, and  the second in the relatively
clean part of town. Each person lived for 5 years in the area.
The  results for 663 males were tabulated according to the
place of  residence,  age, and smoking habits. The rate of
chronic bronchitis was 11-15%  in the 25-34 age group, and 32%
in the 45-54 age group. Smokers suffered chronic bronchitis
more than non-smokers.  There was no significant differences
between prevalence rates in polluted and non-polluted areas. It
was  concluded  that the prevalence rate is not an exact mea-
sure in determining the role of air pollution in causing chronic
bronchitis. A   long  term  investigation  was recommended.

The  existence of fundamental  differences and discrepancies in
the data on toxic concentrations  of sulfur dioxide  has led to a
program to investigate the relationships between concentration
and injury in a  series of experiments with the  effects of fumes
on older spruce seedlings and seedlings of other woody plants;
and of utilizing the data obtained from the established network
of stations for the automatic recording of sulfur dioxide in the
atmosphere of the forests in Krusne hory. The network is par-
tially linked to  the extensive control system in the area below
                         Krusne  hory, the  Podkrusnohori,  and  in  communities  in
                         Krusne hory. The purpose of the measurements were as fol-
                         lows:  establish the range of SO2 concentrations in this area;
                         compare the measurements with the degree of damage, espe-
                         cially  in the old spruce stands; and measure the trends in SO2
                         concentrations in the area under influence of emissions. A net-
                         work  of  four analyzers furnished  continuous measurement
                         data obtained at one-minute intervals, showing values of SO2
                         concentrations in  the  atmosphere expressed  in mg/cu m air.

                         tion. Results are summarized in tables and suggest the follow-
                         ing  conclusions: (1) concentrations of sulfur  dioxide causing
                         injury to forest plants in both  localities are lower than the
                         limits  of  toxicity  presumed so  far; and (2)  maintenance  of
                         levels not exceeding the acceptable level did not  protect the
                         spruce stands from injury.

                         covered 85%  of the area surveyed. Analysis of tree rings  by
                         borings  showed a  significant decrease  in growth  rates  of
                         spruce stands in the last  10 years.  Spruce  fascicles were
                         shown to have the ability to store sulfur, but no relationship to
                         the degree of tree damage was  established. Analysis of the
                         fluorine content in  bark and of variations in acidity of the
                         humus layer were also carried out, the degree of acidity does
                         not appear to be  correlated with the degree of injury. Trace
                         elements found in the  humus were in concentrations too small
                         to be phytotoxic. A survey of existing and planned emission
                         sources was made, including nearby areas of Germany, and a
                         permanent network of 12 measurement stations for continuous
                         atmospheric  samplings   of  sulfur  dioxide   and  dust  was

                         stations will also make relevant meteorological observations.

A study was conducted to determine the degree of contamina-
tion expected in the air over Mexico City during the period of
the  19th  Olympic Games.  Measurements were conducted
through November 1968 in order to establish immediate com-
parison with  the Olympic  period. Recognizing  that vehicular
activity would be greatest in the  areas adjacent to the games
and other tourist attractions, the  study  attempted to obtain a
correlation between the number of vehicles in circulation and
the  degree of contaminant  concentration. At the same time,
meteorological parameters  that influence concentrations were
measured. A set of analyses made on air filter samples during
October  and  November 1968 is  presented. Concentration of
carbon monoxide and methane in the air samples and the total
of suspended paniculate matter and lead in the filters was also
obtained. The concentrations of  detected contaminants were
correlated with  transit parameters (velocity, flow, and vehicle
concentration),  taking into  account the residual variables rela-
tive to  meteorological phenomena. A regression  equation to
compute ppm carbon monoxide as a function of temperature,
vehicle  flow, and the  amount of methane was derived. Con-
taminant concentrations indicated that a critical condition ex-
ists in Mexico City.

In large areas of North Rhine Westphalia, especially along the
heavily industrialized  areas  of the Rhine and Ruhr Rivers,
measurements were performed to determine the distribution of
sulfur dioxide emissions. Measurements were made at 5280 lo-
cations in accordance with  a statistical plan. Emission distribu-
tions for the  entire supervised region are presented on maps.
Comparisons of current values and values obtained in; previous
years are presented for the Ruhr Valley and selected towns
and counties. The  trend indicating a continuous decrease in
sulfur dioxide emissions for most cities and counties of the re-
gion  which  was  observed  during previous  measurement
periods was not continued  during the 1967-1968 period. While
23 cities and counties continued to decrease, 23  others showed
increases. All cities and counties in the western and southern
sections  showed an increase of  about  10%.  The counties of
Kempen-Krefeld, Rees, and Dinslaken showed increases of
about 20%. The program of air  quality monitoring will con-
tinue during 1969.

As part of a project to determine levels of sulfur dioxide safe
for plants, six stations were established in the vicinity of an
iron mine and stocked with agricultural and silvicultural plants.
Sulfur dioxide concentrations were  measured continuously
with an electroconductivity analyzer. The calculations required
to identify  constantly varying ground  level  concentrations in
terms of parameters  defining mean concentration, concentra-
tion-time- intergral, variations in concentration, frequency of
recovery periods, and frequency of concentration peaks are
described. Because of their importance in relation to the  onset
of pollution effects, five weighting factors were formed from
the individual parameters which characterized the pollution
conditions.  These in  turn were reduced to a single degree of
hazard comprising those  parameters most important to charac-
terize pollution with  respect to its effects on plant response.
The mathamatical/statistical analysis of the degrees of hazard
indicated that with this  characterization, the pollution  condi-
tions at the  individual  experimental  stations  could be dif-
ferentiated. Although the components  of the hazard from SO2
can be characterized by means of the degree of hazard, it is
not yet possible to draw definite conclusions about the  onset
of damage  to  the plant  from the degree of  hazard. The data
from the extensive statistical analyses of SO2 measurements at
the six stations are presented. (Author conclusions  modified)

A method used in the evaluation of assessment for industrial
plants causing smoke damage to exhausts  is reviewed and
described. When exhausts differ chemically, it is better to limit
the proportions by air analysis than from damage symptoms. A
local-terrain diagnosis is necessary. Conversely, the enumera-
tion of emissions is a procedure which offers favorable results
at comparatively little cost, particularly in  the case of large
damaged areas and numerous emission sources. A large-scale
diagnosis was carried out in the  Dubner Heide area affected
by  factories in the vicinity of Bitterfield. The procedure is
described. Calculations  using this method show an  error of
plus five percent for a straight-line   polygonal test pattern.
Emission maps of eight most important large-scale  emission
sources in the Bitterfield area were used in  order to calculate
their share  of the damage in the  zones of the forests at Ros-
sau, Dubner Heide, and  Torgau. The results are tabulated. The
percentage  shares are  shown separately for each  zone  of
damage. The mean heights of stacks and sulfur dioxide values
show that factories with the highest rate of  emissions usually
contribute the  greatest  share. Low stacks  and presence of
forests always cause increased values, particularly in heavily
damaged zones.

The Cyclone-Hi-Volume Sampler, the High Volume Sampler,
the Tape Sampler, and Digital Indicator were used to measure
the suspended  paniculate  matter  in  the surface  air  over
Hawasaki City, Japan,  between  July 1968 and  January  1969.
Factors  measured were as follows:  total dust, respirable dust
(less than 3.3 micron diameter),  soiling index, and counts per
hour (cph) as measured  on a digital  analyzer. Correlations
were made among the results obtained. A high degree of rela-
tionship was observed among the results from the first three
systems, but the digital analyzer showed poor correlation. This
was attributed to the deposition of particles on the wall of the
sampling duct. The  increase in dust density observed in the
winter readings is attributed to heating requirements superim-
posed upon the continuing  industrial fuel  burning require-
ments.

The results of an analysis of three sets of samples taken from
the vicinity of an obsolete pitch-coke oven, at  various times,
at various  distances from the works, and at points lying at
various directions away from it are given. The first series were
of deposits of dusts; the  second series were of sedimentation
samples; and the third series were of aspiration samples. The
analysis of all three samples  showed  that exceptionally large
amounts of carcinogenic hydrocarbons, in particular 3,4-benz-
pyrene,  escaped into the surrounding area. Subsequently,  on
special government instructions aimed at ensuring a healthy at-
mosphere, the coke ovens were equipped with special devices
to provide additional combustion of exhaust gases.  Analysis
showed   that after  reconstruction  of the  coke ovens,  at-
mospheric  pollution in the vicinity of the pitch-coke  works
sharply diminished.

AIR POLLUTION AND RELATED  DISEASE OF INDUSTRI-
AL DISTRICTS IN NORTHERN KYUSHU. (Kita Kyushu ko-

Text in Japanese. Nippon Koshu Eisei Zasshi (Japan J.  Public
Health), 16(14):913-920, Nov. 15, 1969.
The results of long-term  measurements of atmospheric pollu-
tants derived largely from adjacent industrial sites in Northern
Kyushu are reported in the form of  tables,and brief comments
on related diseases, which are typically prevalent in industrial
areas, although definite relationsip between those diseases and
the air pollution are not conclusively demonstrated because of
the lack of data on cigarette smoking. The  northern parts of
Kyushu are grouped to five districts and the five districts are
also classifie by the regional differences; industrial, business,
and residential. Each of the average values obtained from the
                        measurements covering nine years shows the dust fall of 23.04
                        g/sq m /month at Yahata-ku, 21.19 g/sq in/month at Tobata-ku,
                        21.39 g/sq m/month at Wakamatsu-ku, 14.53 g/sq m/month at
                        Kokura-ku, and 14.43 g/sq m/month  at Moji-ku; with sulfur
                        oxides by use of PbO2 method 0.619 mg/100 sq m/month at
                        Yahata-ku, 1.045 mg/100  sq m/month at Tobata-ku, 1.011
                        mg/100 sq  m/month at  Wakamatsu-ku,  0.714 mg/100  sq
                        m/month at Kokura-ku, and 0.637 mg/100 sq  m  /month at
                        Moji-ku. Analysis of dust fall with respect to the type of area
                        indicates a dust fall of 27.4 t/sq km/month in the industrial
                        area, 18.35 t/sq km/month in the business area and  13.56 t/sq
                        km/month in the residential area and with sulfur  oxides of
                        1.060 mg/100 sq m/month, 0.745 mg/100 sq m/month, and 0.603
                        mg/100 sq m/month respectively. Analysis  of the related  dis-
                        eases indicates that prevalences of chronic bronchitis, respira-
                        tory system disease, and eye diseases are found highest in the
                        industrial area in  accord with the level of  atmospheric pollu-
                        tants with some exceptions of bronchial asthma,  nasal catarrh
                        and lung cancer. In  connection with lung cancer occurrences,
                        3.4-benzpyrene concentrations were also measured  and tabu-
                        lated.

                        The natural sources of beryllium are  described,  and some of
                        the use to which it is  being put are  mentioned. Occuptional
                        hazards related to beryllium include berylliosis and respiratory
                        cancer. Maximum allowable concentration for beryllium is 1-2
                        micrograms/cu m/8 hrs. The  ambient  concentration of berylli-
                        um in 5 Polish cities is measured. Although the reported values
                        are higher than comparable cities of other countries, the levels
                        are still lower than  the recommended maximums. Because of
                        the lack of data regarding atmospheric concentrations in the

In accordance  with the Emission Protection Law of Northr-
hine-  Westphalia, sulfur dioxide concentrations were  deter-
mined at 5280 sites from November 1, 1966 to October 1967.
The measurements were evaluated with reference to variable
space with the  aid of an  electronic  data processing system.
The  calculated  emission  magnitudes for S026 unit surface
areas, each 1 sq Km in size, were tabulated and illustrated in a
topographic map. In addition, the freequency of occurrence of
certain loading levels was  determined for individual city and
rural areas of the survey district. A comparison of the results
with those of  two other measuring  years indicates that  the
loading  has decreased in  almost  all districts. This  report
describes special investigations conducted for the first time for
the purpose  of determining changes of loading with respect to
time; they were conducted for the heavily industrialized Ruhr
area. This evaluation variable  with  respect to time indicates
which changes  in  sulfur dioxide loading  in urban  and rural
areas of the Ruhr occurred during the course of the third sur-
vey, and that the loading in all these districts has decreased.
The supervision of sulfur dioxide emissions will continue until
1968.

The  concentrations of elements such as iron,  manganese,
nickel, lead, zinc, copper, chromium, and cadmium were mea-
sured in Tokyo. The apparatus used  included  a Perkin Elmer
atomic absorption spectroscope and  a Staplex  hi-volume sam-
pler. The data obtained from the measurements are tabulated
and compared to the values obtained by the Ministry of Health
and Welfare at Japan Environmental Sanitation Center using
photo-emission  spectroscopy.  Considering the maximum al-
lowable concentration of heavy metal elements in the environ-
ment as one-hundredth that of the working environment, cal-
culations showed that lead was  closest to the maximum al-
lowable concentration. This is probably due to automobile ex-
haust emissions.

Results  concerning the heavy  metal  components of settling
dusts in  the  industrial  districts of  Iwate Prefecture  are
described  (Kamaishi, Kuni, and Higashiyama), especially tak-
ing into account Ofunato, cement-producing town. The results
obtained from the earlier investigations were  re-examined, and
toxic heavy metals in settling dusts were determined more ex-
pediently by means of the recently acquired atomic absorption
spectroscope. Metallic components characterized  the various
areas(industries); of all toxic metals  under  scrutiny,  copper
and zinc were found in all areas. In Higashiyama, the amount
of calcium contained in the urine of the residents (average of
660 mg/1)  was much larger than that of  the factory workers
(530 mg/1). Further investigation of the toxic metals in settling
dust is considered to be necessary in order to reveal their rela-
tionship with the biochemical effects on human health.

Carbon monoxide was sampled by means of a Mylar bag at a
busy traffic intersection (12,000 cars/day) in  Yokohama. Sam-
pling was  conducted at 36 locations within 100-m radius of the
intersection. Carbon monoxide was then analyzed by  a non-
dispersive infrared analyzer. The maximum concentration was
found not at the corner of the intersection,  but at a location
about 30 m away where traffic was most congested.  The infil-
tration of  pollution to the general area is such that in the up-
wind direction, the concentration is reduced to  half  within 30
m, whereas  in the downwind direction, the  distance is about
twice as much. Another set of samples taken at the central lo-
cation of  Yokohama showed that when the  carbon monoxide
at ground level is only a few ppm in concentration, there is
not much change in concentration up to about 14  m above
ground. However, when  the  concentration  is over 10 ppm,
concentration is halved at the distance of about 10 m from the
ground.

ON POLLUTION FROM CADMIUM OF MIKKAICHI SMEL-
TERS, NIPPON MINING CO.  (Nikko Mimmaichi  seirensho

(Japan), Public Nuisance Section, May 29,  1970.
In May, 1968, itai itai disease  came to be recognized  by the
Ministry of Health and Welfare as originating in cadmium pol-
lution. OCadmium pollution  of the Mikkaichi Smelter was ob-
served for the  first  time in September,  1969. After the in-
vestigation by the Ministry, the area around the Mikkaichi
Smelter was designated as requiring observation. The data of
the investigation, which lasted  a month, showed that floating
dust was  160 microgram  per 1 cu m, which is less than in
Osaka or Tokyo. Tokyo s  was 200 microgram and Osaka s and
Kawasaki s  was 250-280 microgram, sometimes reaching 400-
500 or even 1000. The average cadmium content in Kurobe
around the smelter, for a month, was 0.31 microgram, per 1 cu
m. The average for eight hours a day, or shorter periods, was
three to five times  as much. The Ministry  based its interim
standards  on eight to  12 hours (0.9-2.9 microgram were stan-
dards), although guidance was given to comply with a lower
figure than the standard. A recheck will be made by the Minis-
try, using  the equipment of the Ministry. Very high cadmium

concentration was found in the soil. In 1968, a few traces up
to seven ppm, averaging three ppm was found in the soil. In
1969, an average of 14.9 ppm, from 4.4 ppm to 53 ppm was
found; S3 ppm was higher than that of Annaka. There is no
standard for cadmium in soil. It does not necessarily follow
that the highe the cadmium content in soil, the higher the cad-
mium content in rice. Cadmium in the soil does serve as an in-
dicator of the cadmium pollution of air. Before the smelter in-
troduced a Cottrell electric dust collector, in I960, pollution
must have been greater. If a man ate 380 g of rice, containing
1.31 ppm cadmium ever day,  he would be taking 0.5  mg per
day from rice. In the area here, the people eat more than 0.3
mg. However, opinions vary as  to  how much is a dangerous
concentration.  X-rays showed that  one had a positive result
Sugar and protein in the urine were lower in the people in non-
polluted area.  Of 24  people who had  positive protein in the
urine, 15 people s  urine was  analyzed for cadmium content
Per litre, there were 3.7-13 microgram, averaging 8.4  micro-
gram, which is less than 30 microgram, thought to be the criti-
cal line by specialists. The residents in  the Mikkaichi area can
rest assured that there will never be itai  itai disease  case
among them.

SULFUR DIOXIDE IMMISSION MEASUREMENTS IN THE
STATE OF NORDRHEIN WESTFALEN. Preprint, State Inst.
for Emission in Nordrhein- Westfalen  (West Germany), 15p.,
1970. 8 refs. Translated from German.
Since 1964, sulfur dioxide emission measurements have been
carried out in large sections of North Rhine-Westphalia, espe-
cially industrial centers in the Ruhr  and along the Rhine, in ac-
cordance  with the  state  s  Emission  Protection Statutes.
Because of the size of the area  and the number of measuring
locations, the  descriptive parameters of sulfur dioxide emis-
sions  are ascertained  by random measurements in conjunction
with spatial spot checking  of unit surfaces one sq km in size.
The results are reproduced in cartographic overviews  (not in-
cluded) and in tables (three of which are included). A clear in-
crease in SO2 emissions  was  observed during  the  current
(fifth)  measuring year.  This is in contrast to  a constant
decrease observed  in earlier years. The trend toward higher
emissions was confirmed by specialized comparative investiga-
tions  of emission leve'« and their  periodic  fluctuations in the
Ruhr district.

The detree of dust pollution and the atmospheric level of poly-
cyclic aromatic hydrocarbons considered to be carcinogenic
(pyrene,      benzo(a)pyrene,      benzo(e)pyrene,      and
benzo(ghi)perylene) were investigated in ten large Polish towns
situated in different  climate regions.  Air samples  were col-
lected at the town center at a height of 8-10 m three  times  a
                        week, using a high-volume air sampler and filters of sintered
                        glass. The filters were weighed and dust concentrations in the
                        assayed air estimated. Extraction of the filters with benzene
                        followed. The extracts were separated by column chromatog-
                        raphy into  appropriate  fractions and spectrophotometrically
                        determined. The 24-hr mean concentrations of dust were high,
                        often exceeding the maximum allowable level of 200 micro-
                        gram/cu m. The content of tar substances in the dust varied up
                        to 20%, but was not correlated with dust levels.  The content
                        of aromatic polycyclic hydrocarbons in the air varied during
                        1966  in  the following  ranges:  benzo(a)pyrene from 29-133
                        micrograms/1000  cu  m,  pyrene from 34-167  micrograms,
                        benzo(e)pyrene     from     14-80      micrograms,      and
                        benzo(ghi)perylene  from 34-125  micrograms/1000  cu m. The
                        lowest dust concentrations occurred  during July  and August;
                        the highest concentrations, in winter.

                        The relation between visibility and suspended particulates was
                        investigated at the Tokyo International Airport for variation in
                        diurnal, annual, and year-to-year trends. The occurrence of
                        poor visibility (less  than 800 m) has gradually been decreasing
                        from  year to year.  Dynamical statistics on poor visibility for a
                        five-year period are presented, including meso-scale weather
                        map  analyses  for  several  poor  visibility  occasions. On  the
                        basis  of  aircraft observations  of the slant visibility, a  sche-
                        matic model for the mechanism of concentration and diffusion
                        of smoke emitted from  factories  is derived. (Author abstract

                        During 1955, a quantitative and  qualitative analysis  was con-
                        ducted on the mold fungi in the air of Moscow. Samples were
                        taken twice weekly, between two and three p.m. A total of 96
                        samples were taken. The two methods used, for bacteriological
                        analyses were Krotov s  slit sampler and Koch s dish method.
                        Each investigation  consisted of seeding the air onto two dishes
                        containing  beer wort agar, both by  the slit sampler and  the
                        sedimentation method. The air samples were taken at a height
                        of  one meter 20 centimeters above ground level. The deter-
                        mination of the number of colonies  of mold fungi and their
                        identifications was  made after incubation of the Petri dishes
                        for five days at 22-24 C. Of the mold fungi found in the  air,
                        those most frequently detected were Cladosporium, Penicilti-
                        um, Alternaria, and Aspergillus. The mold-fungi spore 'content
                        in the air is affected strongly by meteorological  factors. The
                        study showed that  in the various  seasons of the year, there are
                        significant  quantitative and qualitative flucuations in the con-
                        tent of mold-fungi spores in the air.

Carbon  monoxide, carbon dioxide,  sulfur dioxide, and dust
measurements  were taken in Lyon, France, on three days of
exceptional pollution in Nov. 1970. Simultaneous meteorologi-
cal observations revealed an important temperature inversion
whose effects  on the  concentration and dispersion of pollu-
tants  are  discussed. Although pollution level  measurements
may succeed in giving  the first warning of a pollution episode,
meteorological  observations  are necessary to  describe the
evolution of the episode and to give a forecast of its occurring
at a certain time.

A SMOG SITUATION IN BUDAPEST  ON JANUARY 22 AND
23 1970.  (Eine smog-Situation in Budapest am 22 und  23.
January 1970).  Text in German. Z. Ges.  Hyg. Ihre. Grenz-
gebiete (Berlin), 17(12):887-888, Dec. 1971.
Each  year the air pollution in Budapest rises  to particularly
high concentrations three or four times during the  months
from November to February. One such condition prevailed on
Jan. 22 to 23, 1970. The individual stages of the smog develop-
ment were studied by means of the measurement of the sulfur
dioxide concentration. Early in the morning of January 22, the
SO2 concentration rose to 3.30 mg/cu m which is 16 times as
high as the maximum allowable long-term concentration of
0.20 mg/cu m and five times as high as the maximum allowable
short-term concentration of 0.60 mg/cu m.  This extremely high
concentration began to subside at 1 pm. The smog began to lift
on January 23 at 9 pm. The average SO2  concentrations were
measured again on January 25.  Measurement of the nitrogen
dioxide  concentration by the Saltzmann  method yielded the
following data: on Jan. 22 at 10 am, 0.10 mgN02/cu m and at 8
pm 0.06 mg/cu m; Jan. 23 at 8.30 am, O.OS mg/cu m, at 10 am
0.06 mg/cu m, and at  12.30 pm, 0.03 mg/cu m. The maximum
concentration was measured on Jan. 22 at 5.30 am with 0.25
mgN02/cu m. The dust concentration rose likewise from 0.30
to 0.40 mg/cu m to 0.74 mg/cu m on Jan. 22 and to 0.84 mg/cu
m on Jan. 23. The sick calls rose parallel with the SO2 concen-
tration.

The  results  of detailed  investigations in the laboratory on
washout and rainout  of SO2 by droplets of known size dis-
tribution and concentration are summarized. The results show
clearly the effect of drop size, intensity and of the chemical
composition (pH-value) of rain and fog on the  scavenging effi-
ciency. The results of the experiments were used as basis of a
model  calculation of the  effect of washout  and  rainout by
natural precipitation at  a given vertical distribution of SO2.
The  circumstances under which  the rainout and washout
mechanisms  respectively become predominant for the  chemi-
cal composition of rainwater at the ground are demonstrated.

OBSERVATIONS ON PLUME RISE FROM A LARGE INDUS-
TRIAL STACK. Waterloo Univ., (Ontario), (Kept. No. NYO-
3685-7.) (May 1966). 86 pp.
Careful photographic observations were made on  the  rise of
smoke plumes  from Lakeview Generating Station, Ontario and
the results were compared with several theoretical formulae.
Data relating to the  stack variables were collected in some
detail.  In a neutral atmosphere a linear rising portion of the
plume  was found to occur beyond a specific  transition point.
Within the limited accuracy of the photographic technique, the
observations confirmed the theoretical result that the height of
the plume  axis above  the source varies as  the  two-thirds
power of the distance downwind.  Increased dilution tends to
oppose plume  rise but the direct effect of instability in the at-
mosphere is to promote rise; under these opposing influences
it  was found that in a dynamically unstable  atmosphere the
plume  is  sometimes above or below a corresponding plume in
neutral conditions.

AREA. Rechnerische Kartierung von Schwefeldioxyd-Relativ-
werten im Industriegebiet Niederlausitz. Angew. Meteorol. (Ber-
lin) S(S):137-140 (1965). Ger.
A survey chart of the mean SO2 distribution over the Nieder-
lausitz industrial area was established. The investigation was
based upon the formula by Sutton as modified by Holland and
Maede-Pasquill. Not  only existing sources but also industrial
emitters planned for this area were taken into account. Dif-
ferences  of  height of terrain  were  taken into account. The
computed chart is reproduced and some of  its  features are
discussed. The effect of deposition is much more favorable in
the Niederlausitz area  with the smoke damages  being  less
pronounced than on the Dubener Heide which was previously
studied. Finally, smoke damage problems are discussed in
general. Attention is drawn to the fact that strips of woodland
can be quite effective in reducing damages to forests due to
sulfur dioxide. This is due to a maxing action.

After discussion of several variable in the distribution of emis-
sions, an aqueous model is described where a vat of NaCl is
permitted to emit a known quality of NaCl with known densi-
ty into a stream of pure water of known  velocity. This model
is considered to be analogous to the situation where smoke is
emitted in urban or industrial situations, and the density of the
salt  solution  is analogous to the  thermal effect on plume
behavior. In the first series of experiments, the salt solutions
were emitted  into water flowing at 0.95, 1.85,  4.25, or 5.95
cm./sec. and the results photographed. In a second series, a
narrower surface area for the distribution of the salt solution
was used.  In a third series, the effect of a large source of ther-
mal emission upon a smaller,  upstream source of pollution was
investigated. If the smaller source did not emit dense enough
solution, the diffusion trail of that source fell into the trail of
the larger, downstream  source. The results are discussed  and
compared  with those seen in nature with reference to the ther-
mal effect of  a large city and with reference to  work done in
Hyde Park on SO2 diffusion by the wind.  Results are graphed,
photographed, and drawn schematically.

Relationships for atmospheric  diffusion  in  various  weather
situations  are important for studying the possibilities of reduc-
ing air pollution from industrial emission  sources.  It had been
observed that the effect of air pollutants is more  pronounced
in the presence of fog. The  interaction between the  fog  and
the pollutants is complex and involves absorption of pollutants
in the water droplets, aerosol formation, chemical reactions,
etc. In the present study a mathematical analysis was made of
the propagation of gaseous air pollutants hi the presence of
fog over  a river. The  equation  for turbulent diffusion was
solved and an expression was derived for the absorption of a
pollutant by the water droplets as a function of droplet diame-
ter,  water concentration, and molecular diffusivity.  The air
pollutant concentration  profiles and transfer coefficients were
calculated in altitudes of 2-80 m. over a 700 m. wide river and

of 0.5 m./sec. The calculations were made under the  assump-
tions that the turbulence over the river is equal or higher than
over the shore, and the river surface does  or does not absorb
pollutants. Concentration profiles in presence of a temperature
inversion were  also calculated for an emission source 100 m.
high and a wind velocity of 2 m./sec. It was shown  that the
pollutant concentration decreased in all layers due to absorp-
tion by droplets in the fog. The fog was shown to accumulate
pollutants  from higher levels. The  results are applicable  to
SO2. Oxidation of SO2 to sulfuric acid and the formation of
smog are discussed.

 Usually only  the productivity of the source is considered in
the theory of diffusion of aerosols from a point source. In the
presen study the precipitation of aerosol from a vertical  jet is
analyzed  means of semi- empirical theories of convective dif-
fusion  and turbulent jets.  The experimental data used in the
theory were obtained with different types of aerosol genera-
tors used in  agriculture. The experiments were conducted for 6
to 20 hours by spraying transformer oil, solar oil and shale oil.
The generator wa truck-mounted and moved at a speed of 4-6
km./hr. perpendicularly t the wind direction. The Aerosol was
collected in cuvettes and on glass plates coated  with zinc
stearate. The precipitation of individual droplet size fractions
was studied  individually and as a poly- disperse mixture. The
proposed  method  for calculating  the precipitation  charac-
teristics of  aerosol sprays was found  to  give results which
were in good agreement with experiments.

A previously proposed method for calculating the  dispersion
of fly  ash  and sulfur dioxide from smoke stacks of power
plants was verifi by measurements made in the vicinity of the
Moldava thermal power plant equipped with 180  m high, 6 m
diameter  stacks. The SO2 concentrations were measured at
wind velocities  from 2 to 6 ml sec a distances up to 9 km  from
the emission sources. Also,  meteorologic parameters at the
tune of the measurements were determined. The  maximum
SO2 concentration calculated  by a previously proposed formu
amounted to 0.26 mg/cu m and the dangerous wind velocity to
2.5 m  sec. The calculated and experimental values  were in
good agreement The height of the smoke plume above the
stack was measured and correlated with the wind velocity. A
previously proposed formula  f calculating the smoke plume
height was modified to give more accurate results.

Experimental data  on  SO2 concentrations  obrained  in the
vicinity of a large thermal electric power plant with 100 m high
stacks in t Shchekinsk region were processed to study relation-
ships between  meteorological conditions  and air pollution.
Graphs of SO2 ground concentrations up to 14 km from the
sources were plotted under cyclone,  anti-cyclone and inter-
mediate  conditions.  SO2 ground concentrations  at  different
distances from the sources were  plotted as a function of tem-
perature. Vertical SO2 concentration profiles versus  tempera-
ture were also plotted at distances of 1, 2, 4 and 10 km from
the source. Horizontal SO2 concentrations profiles as a func-
tion of wind velocity were obtained. The SO2 concentration on
the ground was found to be at most only about 0.4 mg/cu m at
a wind velocity of 0-2 m/sec, while at velocities of 3-6 ml sec it
reached maximum of 1.8 mg/cu m at a distance of 4-8 km from
the source. Th situation is explained by the effect of the wind
on the direction o the smoke plume. Relationships between the
turbulent transfer coefficient on the ground and the  ground
concentration were also studied. The ground concentration in-
creased with increasing transf coefficient. Low transfer coeffi-
cients in winter were always accompanied by low  SO2 concen-
trations.  It appears that variations the  transfer coefficient can
be used for predicting air pollution.

Sulfur in atmospheric precipitations occurs in  form of SO3,
SO4 and Sions. However, in most analyses only the sulfates
are determined. I the present study SOS  and SO4 ions were
determined  i  rain  and snow collected  during  winter and
summer  months.  The SO3  content decreased  within  several
days of storage in zero which is explained by oxidation  of SO3
to SO4 and the decomposition of  SOS t SO2. The  SO3 concen-
trations of fresh precipitations  were generally much higher in
winter than  in summe. This is  explained by higher concentra-
tions of SO2 due to coal combustion and the higher solubility
of SO2 in water at lower temperatures.

Air pollution data collected by the Main Geophysical Observa-
tory were  analyzed to establish relationships between air pollu-
tion and the  synoptic climatological situations in cities. Con-
centrations of dust and sulfur dioxide were plotted as a func-
tion of geographic location, season, month, synoptic situation
and pressure anomalies. The  analysis  showed that there is a
specific dependence  between  the synoptic  situation (an-
ticyclone,  cyclone) and air pollution. Stationary anticyclones,
which are  usually accompanied by intensive air pollution, are
characterized by weak winds, the absence of transfer in the
lower layer (3-5 km.), and pressure inversions at 1-2 km. The
main  cause  of air pollution  under these  conditions  is the
absence of removal of pollutants by horizontal transfer.

power plants. The basic characteristics of the air flow were
also tabulated. The components of the turbulent energy were
then calculated.  Convection contributed most in summer and

A state-of-the-art study is presented on atmospheric diffusion
and air pollution. A  total of  60 theoretical  and experimental
studies carried out by the Main  Geophysical Laboratory are
reviewed.  The studies deal mostly with mathematical relation-
ships describing the dispersion of air pollutants under different
meteorological conditions. Some  of the topics discussed  in-
clude relationships for the turbulent transfer coefficient; equa-
tions describing turbulent diffusion of heavy pollutants; the ef-
fect of thermal stratification on turbulent  transfer; dispersion
studies based on experiments with smoke  screens  for crop
protection; calculations of fog dispersion;  and theoretical stu-
dies on the diffusion  of  carbon dioxide of pollutants emitted
from  high sources.  The Main  Geophysical  Laboratory, in
cooperation with the Leningrad  Ship Building Institute, is stu-
dying the formulation of equations which describe  the flow
structure;  experiments are carried out with a model of a hill in
                         a wind tunnel.  Comprehensive  studies of air pollution from
                         high smoke  stacks have  been carried out in the vicinity of
                         power  plants  in  Cherepetsk,  Moldavia,  and  Shchekinsk.
                         Methods  for calculating air pollution from power plants have
                         been developed and are used in the design  of power plants.
                         Recently, comprehensive studies of air pollution in cities have
                         been conducted by a special department of the Laboratory.

                         well as research in air pollution. Cement dust emitted in  1964
                         alone amounted to 1.5 million  tons. Large heat and electric
                         power plants are presently installing ash collectors which are
                         95% effective, but even the small percentage emitted causes
                         significant pollution because of the sheer volume  of burned
                         fuel. Desulfurization equipment is lacking. The effect of pollu-

                         distribution of the pollutant and  meteorology.  Ground level
                         temperature  and wind  velocity  measurements are  no longer
                         sufficient since so many emission  sources  are high above
                         ground (200-300  m.).  Meteorological  studies at  the  Main
                         Geophysical  Observatory are dealing with  the first several
                         hundred meters of air and include the development of mathe-
                         matical equations for atmospheric  diffusion from tall emission
                         sources as well as formulas for initial escape  velocity of pollu-
                         tants and for pollution concentration. When an air layer with a
                         weakened turbulence is directly superimposed over the emis-
                         sion source,  the concentration of the pollutant more than dou-
                         bles, while if such a layer is 100-200 m. above the source, the
                         concentration is much less. Results of practical research con-
                         ducted near  the three heat and electric power plants with the
                         tallest stacks in Russia during the period 1961 through 1965,
                         using  ground-level and  air-borne  equipment,  agreed with
                         theoretical data  and  led to the compilation of 'Provisional

                         planning  new power plants. Regular pollution determinations
                         were started in 50 larger cities beginning in 1966, mostly using
                         automatic recording equipment.  Results of research in several
                         large industrial cities of the Ukraine, Urals  and Siberia have
                         shown  that air pollution is greater in cities  with unfavorable
                         meteorological conditions; in most  cases, pollution is more
                         severe in summer than in winter.

al agglomeration area, as a function of the frequency distribu-
tions of the meteorological parameters, is carried out mathe-
matically as follows: After drawing up a complete list of the
emitters, a list which takes into consideration, separately, all
individual emitters with an SO2 emission of more than 1 kg/hr,
and also includes the emission of  domestic fuels  in a suitable
manner, the super-imposed concentration field is calculated, as
a  function  of   the  established   frequency  distributions  of
meteorological parameters, for each point of a grid, with the
aid of a model which is based, for the individual sources, on
GAUSS distributions of the concentrations.  It was found that
in the case of Bremen the influence of the individual (industri-
al) emitters  on the parameters of  the ground-level concentra-
tion is secondary to the influence  of domestic fuels. In every
case it became very clear that the ground-level SO2 concentra-
tion for  a given period of time  varies from  point to point
within the area  under consideration, and that a mean concen-
tration value, determined perhaps  by measurement at a given
point, is  not suitable for the  characterization  of the SO2
ground-level concentration either  for this point or for other
points of the industrial agglomeration area.

AN ANALYSIS OF THE SURFACE BOUNDARY LAYER IN A
REGION OF LAND AND SEA BREEZE. Taiki Osen Kenkyu
(J. Japan. Soc. Air Pollution),  l(l):46-54, 1966. Translated from
Japanese. 31 p.
A study of the dispersion conditions for  waste gas in  the
coastal  region consisted of an  analysis of  the land  and  sea
breeze,  and meteorological  observations of  the  lower  at-
mosphere (by  means of a captive balloon) to determine the
characteristics of the boundary layer which forms in the region
of the land  and  sea breeze. The height of the boundary layer
that formed in  the  region of land and  sea breeze showed a
distinct  diurnal  variation. At sunrise, the boundary layer  was
300 m  high. It  had developed overnight by the  land  breeze.
Between 9 and  10 am during the  switch from  land breeze to
sea breeze, no boundary layer could be observed. The bounda-
ry layer began to build up again from a height  of SO m to ISO
m when the sea breeze began  to blow. The height of the boun-
dary layer was  in close connection with  the atmospheric  sta-
bility near the ground surface. The maximum height of 300 m
was at  neutral  conditions; at stable or unstable atmospheric
conditions, the  height was always less. The  roughness of the
ground was large when the wind  velocity was weak, while it
suddenly decreased when the wind velocity became strong. It
was about 20 cm at a wind speed of less  than  1  ml sec  and
below 5  cm at  a speed of more than  2 m/sec. The frictional
velocity was one- tenth as large as the wind velocity at about 1
m above the ground.

TURBULENT DIFFUSION  IN THE ATMOSPHERIC  BOUN-

An attempt is made  to develop  a theory for predicting  the
growth  in  the thickness of a cloud  which is  diffusing in a
leeward  direction from a continuous  point source.  Neutral
stratification is  contrasted  with nocturnal thermal stratifica-
tion. With respect  to leeward axial  concentration and  the
thickness of a cloud adjacent to the earth's surface, the theory
is compared with diffusion data obtained in experiments con-
ducted on a flat topography. (Author abstract modified)

The humidity of air exerts a considerable influence on the tur-
bulent state of the lower layer of air above the ocean (as well
as above very wet land areas). It affects the magnitude of the
gravitational force in the first place; in the second place, at
high moisture contents,  air strongly absorbs radiation of long
wave-lengths, so that the heat influx due to this  process must
be taken into account. The turbulent entropy flux in humid air
is not proportional to the turbulent heat flux, as it is in dry air,
but includes a  turbulent flux of moisture as well.  The latter
has apparently  been over looked up to now. Using analytical
expressions  incorporating terms  representing the  effect  of
moisture, as well as heat flux,  energy, and momentum equa-
tions, expressions are derived characterizing the velocity, tem-
perature and humidity profiles of the lower layer of air above
the ocean; taking the statistical homogeneity of the undulating
ocean surface into account and restricting them to steady-state
conditions. Particular cases are considered  in which the  ex-
pressions for the dimensionless  functions used to characterize
the above profiles assumes forms which agree with experimen-
tally determined profiles in these particular cases.

Turner's classification  system  for dispersion categories was
developed to deal with  questions  of air pollution. It is based
on hourly cloud observations conducted by weather bureaus
on the radiation intensity figured out indirectly  from the an-
nual and diurnal  variation of the sun elevation  and on mea-
surements of the wind speed. The system is built around the
idea by Pasquill, according to which the atmospheric stability
near the earth's surface is primarily a function of solar or ter-
restrial radiation proportional to the degree of cloudiness and
the depth of  the  cloud layer.  By including  the amount  of
clouds and the  height of the cloud layer, radiation changes are
to some extent reflected by the system. The method can  be
programmed and fed into a computer. This method is applied
to central European climates, and the results of the application
are discussed.

At the  smoke stack of the Schilling power plant near Stade,
Germany, air  temperatures  were recorded at ten altitudes
between 2 and 200 meters. These records provide a means for
studying temperature variation with  altitude. On the basis of
records made during the summer, the build-up of the nocturnal
ground inversion can be studied. After sunrise,  it disperses
from the ground upwards. The course of this dispersion and its
effect on the  spreading of flue gases  are followed. A few
hours before sunset, a stabilization sets in at the high altitude
and can  first be observed  when the  good-weather cumulus
clouds begin to  dissolve. The course of this stabilization at the
altitudes below 200 meters is estimated on the basis of changes
of the temperature gradient at the various altitudes. After sun-
down and at the start of the negative radiation balance, there
is again a build-up of the inversion from the ground upwards,
while at the high altitudes,  a temperature decrease continues
for some time.

The  method of determination of the coefficient of horizontal
diffusion according to a visible outline of smoke from industri-
al smoke stacks is discussed.  Studies  of atmospheric  con-
tamination  in  1962-1963 in  area of  the  Shchekino State Re-
gional  Electric  Power Station determined  the parameters of
horizontal diffusion according to data of aircraft observations
of the  smoke plume. A total  of 20 flights was  made  to  a
distance where  the plume ended, a point where the concentra-
tion was considered equal to zero. It was found that the mean
dispersion as a function of time varied from 0.1 to  0.2 depend-
ing on  weather conditions,  but its absolute  value remained
constant to a distance of 30-40 km from the source. The ob-
tained  data was compared  with characteristics of horizontal
diffusion by Sutton. The mean dispersion as a function of time
was  recalculated to the  parameters used in other  studies and
foupd  to be  0.1 to  a  distance of  25  km. (Aujjior abstract

                        it is the Lambda criterion which is decisive for this case. The

                        A  mathematical model  is developed to  incorporate  the
                        meteorological factors influencing the dilution  of atmospheric
                        pollutants from a point source, with a view towards optimizing
                        the location of such installations as electric power plants. The
                        model takes into account wind direction, wind  speed, vertical
                        wind profile, and thermal  stratification by use of  the equation

                        meteorological data can therefore be  obtained rapidly. The
                        method is applicable to sites at which ground level and upper-
                        air wind observations have been made for at least a year or

Meteorological and aerological data were collected on the dif-
fusion of sulfurous gas and ashes from stacks of thermal elec-
tric power stations from 1961 to 1963.  A method for analyzing
the experimental data on surface concentrations  at various
distances from the plants was described in  detail and con-
trasted with  conventional methods of finding average sulfur
dioxide concentrations. The method permits the determination
of maximum SO2 concentrations and calculations of dangerous
wind speeds. The results obtained by the method were in good
agreement with theoretical calculations. Maximum  SO2 con-
centrations at all sampling points were related to the  wind
speed, which depended on the initial flue gas exit speed from
stacks and the degree  of their overheating. At low  speeds, flue
gases rise to a great  height. At higher speeds, the effective
height is small, but the gases are dispersed  over a greater
distance. Rapid increases in  surface concentrations follow ini-
tial increases in wind speed, but only very  small changes in
surface concentrations occur thereafter.

tained empirical research findings by a simulation method. The
data will be stored in a data-bank to be available for computer
analysis whenever  new factories or land reformation projects
are planned  in a concerned area. The  air pollution simulation
system will correlate all possible data  on air pollution existing
in  the areas  of coastal plants  with  geographical features,
weather  conditions,   existing  atmospheric inversion  layers,
smoke dispersion factors, regional capability  for  plant con-
struction, layout of equipment, qualitative and  quantitative in-
vestigations of fuel consumed, numbers of chimneys and their
height, amount of smoke discharged, variation  of temperature
and wind speed, sulfur dioxide density, and so forth. All these
variable will be used as  computer input. The experimental
findings obtained from the wind tunnel test are to be applied
to the simulation system, which is expected to cover the fac-
tors associated with complicated geographical influences or at-
mospheric inversions relatively  indigeneous to coastal regions
in Japan. Two methods of simulation are considered applica-
ble; simulation of the spot data  on weather analysis,  statistical
treatment of collected records on air pollution, characteristics
of smoke dispersion, and correlation air pollution patterns; and
simulation by «  wind tunnel  test, the latter  considered more
practical under present circumstantial provisions. The  mathe-
matical  model  for the air  pollution  simulation system is
discussed.

forecast purposes, the territory of the USSR is divided into
four regions:  1) a major portion of Eastern Siberia, where at-
mospheric stagnation is observed up to 25 days of the winter
months; 2) the western European sector and northern foothills
of  the  Urals, where  moderate repeatability  of atmospheric
stagnation is  observed;  3) the  northeastern  European  sector
and forest region of Western  Siberia, where atmospheric stag-
nation is observed only in spring and winter; and 4) an area
comprising Kazakhstan, Povolzh'ya, the northern section of
Middle Asia, a large part of Western Siberia, and the  shores of
marginal seas where stagnation  almost never occurs  (1-2 times
in 5 years).

(II).  Taiki Osen Kenkyu (J. Japan Soc. Air Pollution), 2(1):70-
77, 1967. Translated from Japanese. 2p.
In the turbulent boundary layer, the vertical distribution of the
•wind speed is represented by the logarithmic and linear type
law. The thickness of the boundary  layer is 30 m to approxi-
mately 300 m, and is  connected with the atmospheric stability.
It is thickest  in the neutral atmosphere and thin in the stable
and unstable  atmosphere. The turbulance intensity of the at-
mosphere in the  boundary layer becomes larger  as the layer
approaches the ground. The vertical  distribution roughly corn-
forms to the logarithmic law. The value of the turbulence in-
tensity is affected  by the atmospheric stability. The  ratio of
the  turbulence intensity  for  1 minute to the average wind
speed exceeded  0.10 in  the  unstable atmosphere.  The at-
mospheric  diffusion  coefficient,  obtained  from this  ratio,
showed  a tendency to be proportional to the square of the sur-
face wind speed.

respect  to mode of decay of the turbulence intensity, self- cor-
relation  coefficient, and spectrum distribution. The mechanism
of the  down-draft in a simple building  model was  also in-
vestigated on the  basis of these data. The chief items that
were  analyzed included the distribution of  the average wind
speed on the  lee of a building and photographic analysis of the

The basic boundary value problem for finding the mean inten-
sity  of  multiply  scattered light  in  a spherical  aerosol at-
mosphere is formulated. The numerical data  obtained on the
brightness of the crepuscular aerosol atmosphere  are analyzed
for a case when the orbit of a space vehicle is high  enough,
and the observer is  in the shadow  zone at a great  distance
from  the terminator  line. Results showed that for aerosol at-
mosphere models,  the  scattering  indicatrices,  theoretically
computed and determined on  the basis of experimental data,
lead to  almost identical results at heights exceeding  10 to 12
km. A pronounced difference in brightness was observed only
in the lower 6 km layer of the atmosphere. Calculations of the
results for absorption of solar radiation by atmospheric ozone
showed a decrease in  the brightness  of  the crepuscular au-

The  results  of experimental  investigations of the  degree  of
polarization  of scattered  forward  and reflected  light  are
discussed, including laser-emission in artifical fog and smoke.
Measurements  were conducted in  a 35  cu m artifical  fog
chamber; a flow of linearly polarized emission from a gas teser
on He-Ne mixtures,  wavelength 0.63 mkm, was directed into
the chamber with a given scattering medium. A  method  of
measurement was used that significantly decreased errors from
the temporary instability of the substances under investigation.
During dispersion of narrow laser beams,  the theory of mo-
mentary scattering describes not only the dependence of scat-
tered light intensity on optical thickness, but also the polariz-
ing ability of scattered forward light.

Systematic wind measurements made in  1964 on a 300-m tower
at Obninsk were used  in  compiling  wind  profiles  during
periods when  the area was covered by low clouds. Observa-
tions lasting two days were made once every two weeks of air
temperatures and wind speeds and  directions. There were 90
instances during which the ceiling was below 300  m. Wind
profiles drawn for these instances  fell  into three categories:
type 1 is characterized by a smooth increase in wind speed
with height; type 2 by the existence of a maximum speed at
some  elevation;  and  the  third  type, by  a  complicated,
frequently S-shaped profile. These main types of profiles are
further subdivided. Type la has stable stratification  with small
lapse rates both under and within the cloud deck an'd has large
wind speed gradients. Types Ib and  Ic have larger lapse rates
and lower wind speed gradients than in type 1 a. On profiles of
the 2a and c types, the lapse rate is of the order of 0.5 deg per
100 m under the cloud deck, 0.6-0.7 deg per 100 m at the cloud
base and 0.4-0.5  deg per  100  m in the clouds. On type  2b
profiles in the lapse rate  is 0.96 deg  per 100 m under the ceil-
ing,  decreasing to 0.5 deg per 100 m at  the cloud base and in
the clouds. The vertical  gradient of the wind speed changes
sign  at the  edge of the cloud base (2a), is somewhat below it
(2b)  and  above it  (2c). Type 3 profiles are characterized  by
sub-cloud lapse rates. (Author abstract)

The dispersion  in  the free atmosphere of irregular-shaped par-
ticles 100-1000  micron in diameter from altitudes of 500-8000
meters and  of  spherical particles 30-100 micron  in diameter
from  altitudes  of  500-1000 meters  was  investigated.  Lu-
minescent sand and plastic particles were employed as indica-
tors. The determining factor in the dispersion of large particles
was gravitational settling. As particle size diminished during
dispersion, gravitational settling assumed less significance and
the influence of atmospheric turbulence increased. In the case
of the smallest  particles, the effect of atmospheric turbulence
completely dominated  gravitational  settling. The  intensity of
the turbulence is determined by the wind field and the degree
of thermal stability of  the atmosphere. Strong winds and un-
stable stratification  contribute to  an increase in turbulent
dispersion. Empirical formulas are given which permit compu-
tation of the surface concentration of particles which have fal-
len from an instantaneous  point source  in a specific distribu-
tion according to descent velocity. An analysis of the disper-
sion factors in impurities of the coefficients of transverse and
vertical diffusion is given. (Author abstract modified)

Control  is  quite difficult of the  automotive emissions of
nitrogen oxides and hydrocarbons  which  contribute  to the
production of photochemical smog, resulting in eye irritation
and plant damage.  In  connection with  this problem,  a brief
description of the effect of solar radiation in terms of wave
length,  energy,  and  irradiation angle  on  the  absorption
mechanisms of various substances is  presented tabularly and
graphically.  Possible chemical reactions due  to the radiation
energy  of fluorescent  light as  well  as solor radiation are
described in terms of reaction formulae.  A smog chamber was
used  to investigate the photochemical effect, while radiation
source was  a set of three hundred 100 W fluorescent lamps
with  the intensity of 1000  micro-W per  sq cm (3450-3550 A).
The chamber which was about 11  cu  m, contained various
measurement devices,  radiation and dilution  sources, as well
as  a  chassis dynamometer to simulate  different  driving and
idling conditions in order to  produce exhaust  gases.  The
general schematic diagram is given. Data are plotted for the ir-
radiation  of nitric  oxide  plus  ethylene,  showing that the
smaller the  initial concentration of NO,  the larger the rate of
increase of NO2 and the faster the formation  of oxidants. The
faster the reaction, the higher the HC/NO  ratio will be. Data
are presented for actual exhaust gases under simulation condi-
tions, and also  for the effects of different types of hydrocar-
bons. Definite relations were observed between the initial con-
centrations of NO and HC and the  resulting  concentration of
oxidants.  Reported connections with many types of HC, such
as paraffin, olefins,  and alkyl benzene,  and the degree of ir-
ritation  of the eyes are quantified in terms of a mathematical
formula. A list of reactivit of organic materials is included, ac-
cording  to  ozone  or  oxidants, peroxides,  formaldehydes,
aerosols,  eye irritation, plant damage, and average reactivity

Meeting of the Japan Society of Air Pollution, 1969.)
By electronic computer analysis of data on  pollutant concen-
trations and meteorological conditions obtained by telemetry, a
differential equation and  its various solutions was developed in
order to calculate and predict the pollution  concentration by
time and location. The first-order differential equation is es-
sentially an adjustment type equation where the time rate of
change of concentration is specified within an  atmospheric
volume (zone) V. The equation  depends on  the parameter of
vertical mixing, the  concentration  in question, the concentra-
tion  of pollutants from the  region outside V, the strength of
emission in the zone, the station  number, and the rate of diffu-
sion  of pollutants.  Some of  the parameters  are determined
from meteorological data, and  the  others implicitly  from a
combination of data. Based on the actual density of pollution
(sulfur component)  at 20 and 110 meter altitudes  on Osaka
Tower, it  was suspected that in the immediate neighborhood
of the tower, the ground level pollution is always concentrated
in winter and that the  effect of the localized surface emission
sources is large. The result of the calculation tended to con-
firm the suspicion.

By using a mathematical model that describes the atmospheric
pollution concentration in a metropolitan area, the concentra-
tion  a few hours away can  be predicted when there is a con-
tinuous  influx of data from the monitoring stations; control
methods for  pollution phenomena that  contain too  many un-
certain  elements can be  probabilistically  determined.  The
mathematical model is  essentially  a first-order differential
equation that is described  by  vector and  matrix  notations,
since the metropolitan area can be divided into N zones over a
discrete time period k. By employing stochastic methods and
optimality calculations, the desired results, the expected value
of the concentration S  hours away and  the  optimal control
variable at zone i and time k, can be determined.

                        tion flights between 1933 and 1944 before the construction of a
                        large power plant near Stade. To determine how stack height
                        would affect mixing in the immediate vicinity  of the  plant,
                        temperature lapse rates were monitored up to  200 m.  On a
                        yearly  average,  167  days with  surface inversions  were
                        counted, one fourth of which reached a height of 200 m and
                        one fourth,  a height of more  than  350  m. Seven eighths  of
                        these temperature inversions  disappeared  by  afternoon. The
                        days on which no mixing occurred averaged about 44 a year.
                        Only one  fourth of the stable weather conditions lasted longer
                        than four days.  The longest  stable conditions prevailed  in
                        December. Analysis  of the temperature lapse rates  showed
                        that  half  of the hours between midnight and sunrise  are
                        marked by temperature inversions which extend to 175 m. No
                        inversions were recorded between noon and 2 P.M. It is con-
                        cluded that high stacks reaching higher than surface haze emit
                        smoke in  a coning plume until midnight, after which stabilizing
                        upper layers change the smoke plume to a fanning one. A spe-
                        cial weather  service  is suggested to guard against emissions
                        during stable conditions.

                        Data are  presented on the variations of air temperature  for
                        zones from  17 to 19  deg north lat and of solar  radiation
                        reaching the earth, over approximately the last 100 years, from
                        1880-1885. A rise in  temperatures which began at the end of
                        the 19th century halted about 1940 and changed to a decrease,
                        with larger  changes in the middle  and especially  the high
                        latitudes.  The radiation curve shows two maxima, one at the
                        end of the last century and a second, more  prolonged peak
                        during the 30's; a decrease began in the 1940's. These  varia-
                        tions are  related  to changes in atmospheric transparency, as
                        when sharp decreases in solar radiation  occur after explosive
                        volcanic eruptions fill the lower layers of the atmosphere with
                        volcanic  dust; average  earth temperatures  may  decrease
                        several tenths of  a degree. With settling  of the dust,  radiation
                        and temperatures increase. The radiation  decrease beginning in
                        the 1940's may be due in part to similar effects on atmospheric
                        transparency from industrial  pollution and nuclear  weapons
                        testing. If the present large quantities of atmospheric dust are
                        of volcanic origin, temperatures may be expected to rise; if no
                        new major eruptions occur; if a significant portion is from
                        human economic activity, the decrease in temperatures may be
                        of long duration. The need for  worldwide data on volcanic
                        eruptions, dust,  atmospheric regimes and solar radiation is
                        stressed.

The results of over 300 meteorological soundings of nocturnal
ground  inversion layers  ia urban  areas  are  analyzed.  The
soundings were conducted by the use of kite-balloons and ad-
balloons in cold weather. In the outer urban area, most of the
temperature inversion  appeared  directly  upwards  from the
ground  surface. Isothermal layers were observed up to 150 ft
from the ground with the inversion elevated about this layer
only on windy nights. This is due to the turbulent mixing flow,
mechanically produced by windward hills or roughness in the
surface  layer. In the central area of the city is a heat-island,
due to the artificial heat  supply. The temperature profile here
is characterized regardless of wind by the elevated inversion
layer, with  a  base  height which  reaches  higher than 200 ft.

An investigation was conducted to establish numerical values
of condensation nuclei in the air of artificially heated environ-
ments. The number of condensation nuclei was determined
with an Aitken counter,  and  an Owens jet dust counter was
used to  determine the particle content of the air. Easic climatic
factors including temperature, humidity, air movement, and at-
mospheric  pressure  were measured. The  outdoor air  in the
center  of  Milan between 11  am  and  1  pm  from January  to
March  1952  contained an average of  100,000  condensation
nuclei/cc.  Inside the rooms investigated, the number of nuclei
was  approximately  50% lower and fluctuated between 32,000
and 74,000/cc. The  lowest levels of condensation nuclei were
found in  air-conditioned  and  electrically  heated rooms and
highest  levels prevailed in environments  heated by coal stoves
associated  with dryness  and irritation of the mucous  mem-
brane of the upper airways. It is believed that data on nuclea-
tion represent useful parameters of air hygiene in different en-
vironments. Further studies on ionization and nucleation are
required to define  the climatic  factor which influence well-
being in confined rooms.

A STATISTICAL STUDY ON THE VISIBILITY FORECAST-

THE MULTIPLE REGRESSION EQUATION FOR VISIBILI-
TY  FORECASTING.  Kishacho  Kenkyu Jiho (J.  Meteorol.

Science Info. Services, 22p., Dec. 3, 1969.
Multiple regression equations  for visibility forecasting were
constructed by using the  HITAC  5020 computer. In  these
equations, predictands are the averaged visibilities in the after-
noon and the minimum visibilities after sunset, and predictors
are  35  meteorological elements  observed in  the morning.
Verification confirms that the  forecasted visibilities  by the
multiple regression  equations  are  close to  the observed  ones;
for instance, a correlation coefficient is 0.637. The relation of
multiple correlation coefficients to the number of predictors
through six multiple regression equations indicates that accura-
cy of the method increases up to 3 or 5, then increases slowly
with the number of predictors employed.  A regression equa-
tion was prepared for each N (N equals  1,2,	20) of selected
predictors out of 35 predictors,  then each accuracy of the the
methods by 5, 10 and 20 predictors was verified; the most ac-
curate method is the one by 10 predictors, then the 5 and 20
predictors follow. (Author abstract modified)

A method for objective forecasting of visibility  by  means of
statistics and correlative analysis  is described.  Visibility pre-
dictors and correlative coefficients are calculated for minimum
visibility in the evening and averaged for days with or without
rainfall. Useful predictors with high correlation coefficients,
such as meso-scale pressure pattern, atmospheric stability, and
wind velocity in the lower atmosphere are selected. By com-
bining these,  some forecasting diagrams are  constructed. The
forecasting method by  these diagrams is  verified as  useful;
minimum visibility in the morning and evening can, in general,
be predicted  within an  error of 1.5  miles. The  method con-
siders industrial pollution in the form of volume and variation
of aerosols. Other parameters considered include cloud cover,
dust-fall,  precipitation,   temperature,  pressure,  humidity,
winds, and inversions. (Author abstract modified)

Meteorological  quantities  of air  pollution implicate altitude
wind, stability parameter,  thickness of the mixing layer,  and
the number of 'Degree-days of heating' (C room-temperature
multiplied by days/year  of  heating).  These  quantities  are
available for the City of Budapest and used in the paper as ex-
amples. The above four quantities, the 'background load' of
pollutants and the emission charateristics of  significant point-
sources of pollutants will define the actual pollution load at a
particular location, as a function  of time. There are  a few
physical  characteristics  of the  load calculation that had not
been adequately defined,  especially the roughness parameter
of the terrain. This latter depends on the vertical profile of the
area and the degree of coverage  by buildings.  Investigations
are underway (both in Hungary and abroad)  to  obtain mathe-
matical expressions for the roughness parameter. When the in-
vestigations are completed, air pollution forecasting for cities
will  be possible, and even smog formation will be predictable
from meteorological data.

Radiational processes in clouds and fogs are considered in the
study of the volumetric factors of absorption and dispersion
and their spectral relationships. Everything discussed relates to
that region of the  spectrum where self-radiation of the disper-
sive substance or gaseous phase does not play a part. Reliable
methods of experimentally determining the true spectra of ab-
sorption and dispersion in clouds and fogs are possible; they
are by no means trivial, and their development requires special
attention.

A theoretical  analysis  of smoke  propagation from  factory
stacks is performed to establish the relationships among the
strength of the source (amount of smoke per unit time), rate of
fall of particles, concentration of admixture, and wind speed.
Both the wind speed and the horizontal exchange coefficient
are considered to  increase with height in an approximation of
true atmospheric conditions. The effect of superheating of the
effluent particles is insignificant within  the framework of the
analysis and is disregarded. Maximum concentration was inde-
pendent of either wind  speed or the horizontal diffusion coef-
ficient; rather, it is wholely a function of time. In the discus-
sion of the effects of the particle, the aerosol is assumed to be
polydisperse, but  the size of each particle  is assumed to be
constant. An increase in the source strength increases the con-
centration only to a limit, following which additional increases
result in a decrease in concentration.

                        means of  a computer, based on the classification of pressure
                        patterns in and around Japan and the pollution conditions cor-
                        responding to each pattern. Detailed data  are listed for the
                        frequency of occurrence of high concentrations of sulfur diox-
                        ide pollution (over 0.1  ppm/ day) for different atmospheric
                        pressure patterns in each  of the fou seasons. The data range
                        from 1964 to 1967. The  pressure patterns that bring high  con-
                        centrations of sulfur  dioxide to Tokyo are South High  type
                        and mobile anticyclones, and the former especially cause high
                        concentrations during winter with high probability.  The effec

                        high sulfur dioxide concentrations  seem to be  still quite dif-

                        It is important to accomplish active early control of pollution
                        sources dependant on the meteorological condition rather than
                        to control the pollution source after a smog alert has been is-
                        sued and the concentration is already high. From such a view-
                        point, the possibility of  early air pollution forecasting was in-
                        vestigated by creating a forecasting check sheet based on the
                        basic  framework of  atmospheric  pressure distribution  over

lion, pH value,  and water temperature. The washout condi-
tions for NO2 are  more  complicated, but the decreases of
NO2 concentration by washout can be approximated by a for-
mula. Washout speeds at  constant precipitation intensity for
both gases  increase as drop size  decreases. The washout
speeds also increase with rising pH of the rain water. Experi-
ments  with  Aitken  cores  result  in considerably smaller
washout speeds than for SO2 or NO2. This results because the
particles are not of uniform size. An  SO2 landing coefficient
for raindrops can be determined which forms the foundation
for the calculation of a sulfate quantity which a rain of given
intensity and drop size distribution contains. The sulfate con-
centration in rain water decreases with rising rain intensity as
a square function.  The  contribution of  aerosols and ground
concentrations of SO2 to concentrations of  sulfate in  rain
water are discussed. (Author conclusions modified)

An analysis is presented  of published data collected in En-
gland fro 1957-1964 at relatively clean air sites on the concen-
tration of nine individual radioactive isotopes of global origin
and chemical compounds in  precipitation  water and in the air.
Isotope washout is  characterized by the ratio of their concen-
trations in precipitation and in air at the cloud-layer altitude.
Relationship are found between the concentration of global-
origin isotopes and chemical compounds in precipitation on the
one hand and the precipitation total on the other. The slope of
these curves yields  the washout rate of the corresponding sub-
stances. Differences are  noted  in the washout rates  of in-
dividual isotopes: zirconium  (95) is the most rapidly scavenged
from the atmosphere,  strontium (90) is washed out better than
cesium (137) and strontium (89), while the washout rate of an-
timony (125) and other isotopes is much less.  Sulfates are
washed out from the atmosphere somewhat less than chlorides
and carbonates.  The washout times of isotopes and sulfates
from the atmosphere are approximately 24 hrs. Washout of in-
dustrial pollutants is better at their origin than far from it An
attempt is made to ascribe  these relationships to features of
aerosol particle  transport and  their future aging  in the at-
mosphere These factors affect the particle sizes, which deter-
mine their rate of removal by precipitation. (Author abstract

To study the combined  influence of natural  and urban land-
scape on the meteorological regime of the  industrial city of
Donetsk, USSR, surface  humidity and air temperature  mea-
surements were taken at points representative of asphalt in the
city proper and bare soil and grass in suburban areas. The
peculiarity of this city is the fact that  is is located on a dis-
sected terrain where the heights are exceeded to a maximum
of 100 m. The investigation  showed  that a heat  island is
formed in the  afternoon hours  and, as  in  other  cities,
manifests  itself best during night  hours in summer  months.
The increased influence of the city on the thermal region is the
result of two factors promoting an increase in  the air tempera-
ture of the city at night: an enhanced heat transfer in  the cen-
tral part of the city and a relative increase in  the air tempera-
ture in this most elevated part of the city.

A series of numerical experiments were performed to deter-
mine nocturnal and  diurnal vertical ozone profiles in the meso-
sphere. The results  suggest that classical photochemical theory
cannot explain the  nocturnal increase  in total  ozone layer
thickness observed  from  the earth. According to the  classical
theory, recombination of  'unimpaired* atmospheric  oxygen
atoms  at night may lead to the formation of additional ozone
at certain altitudes.  Errors are assumed to have been  made in
the numerical experiment.

Multivariate statistical analysis was performed on the  relation-
ship  between meteorological data, such as atmospheric pres-
sure patterns,  wind speed, and atmospheric stability,  and sul-
fur dioxide levels up to 10 hrs after the meteorological mea-
surements. By feeding a forecasting equation  to an electronic
computer and giving it the meteorological data inputs,  the con-
centration of SO2 several hours hence can be predicted. The
forecasting equation was  constructed by means  of screening
procedures, which assume that the factor to be predicted can
be  expressed  as   a  linear  polynominal  equation   of  the
meteorological factors, and that the coefficients for those fac-
tors can be calculated in order to maximize the multiple cor-
relation coefficient. For the multiple regression equations, ten
to 20 factors were optimal. Some of the factors taken into con-

When sulfur dioxide concentration continuity is made to cor-
respond to air pollution potential,  the positions  of migratory
anticyclones and extra-tropical cyclones that appear in western
Japan between late autumn  and winter are  of interest. A
method  is  described whereby air pollution  potential  can  be
determined, with the  aid of  computer,  from the forecasting
weather map published by the Meteorological Agency. Criteria
for a day of high potential pollution are as follows: Osaka is
within 6 mb from the center of the anticyclone; atmospheric
air pressure differential  is within 6 mb in the region 30-40  N,
130-140  E;  a cold front is closing in fro the Sanin area; a sta-
tionary front exists  north of 30 N; and  Osaka is between two
cyclones.  Similar qualifications are given  for days  of low
potential and intermediate potential. A test  run based  on sets
of data obtained at 9 am  of the day prior to the forecast
showed that for most cases, the accuracy was over 80%.

Multiple regression  analysis  was  performed on a matrix of
meteorological data and air pollution data for Tokyo.  The  air
pollution data  covered concentrations  of  nitrogen  dioxide,
nitric oxide, carbon monoxide sulfur dioxide,  and suspended
particulates. Meteorological data were atmospheric pressure at
sea surface, temperature, vapor pressure,  relative  humidity,
wind speed and  velocity, cloud amount, present temperature,
rainfall, and visibility. With respect to the relationship between
the winter pressure patterns  and  air pollutant concentration,
pollution becomes stationary and concentration increases when
the migratory  anticyclone is in transit or when the  trough of
atmospheric pressure  is in  transit. The  pollution will be dis-
sipated  when  the pressure pattern  is the  typical winter-type
west-high and east-low and the pressure variation is the largest
between lat 30-40 n and long 135-145 E, or when the cyclone
passes  by  as it  develops along  the southern  coast, or im-
mediately after the transit of a front.

                         Laboratory tests were carried out to investigate the possibility
                         of mist formation on hygroscopic nuclei of humidity condensa-
                         tion. The stability of mist formed and the effect of humidity
                         on it were studied. The laboratory results were applied in the
                         open air. It was possible to form a mist on hygroscopic nuclei
                         of condensation at a relative humidity much lower than satu-
                         rated. The following gases  proved to be  active in humidity
                         condensation: sulfur trioxide, phosphorous pentoxide, nitrogen
                         dioxide, nitrous oxide, and hydrochloric acid. The stability of
                         mist formed is  connected with the chemical nature of active
                         condensation nuclei. Gases with considerable affinity to water
                         form mist  with large droplets. Stability of the mist depends on
                         the  size of droplets and is  highest for medium-size droplets.
                         The results showed that under certain conditions it is possible
                         to form a mist on hygroscopic nuclei of condensation.

                         Two synoptic criteria are defined for the prediction  of  high
                         sulfur dioxide concentrations in the Rouen region of France: a
                         period of 24 hours during which the mean wind velocity is less
                         than 3.0 m/sec, and  a forecast of  a similar situation for the
                         next day.  At the present time, the proposed method, which
                         uses only information contained in the daily forecast of the
                         Meteorological  Office,  is  the  only  practical method.   The
                         mathematical diffusion models and the empirical diffusion for-
                         mulas  need numerical weather data, which are not available
                         for the next day. Thus, they cannot be effectively used in a
                         particular  forecast; they can only be verified in retrospect. The
                         proposed  empirical  method allows pollution  forecasting in
                         calm periods. The mathematical diffusion models and empiri-
                         cal  correlation  formulas have  singularities when the   wina
                         velocity approaches zero, and, therefore, cannot be used for
                         calms. The r.m.s.  error of the present method is less than that
                         of mathematical models, even when calculated for days of the
                         highest pollution in the winter. The principle of the proposed
                         forecasting method is valid for other towns and regions, but
                         the numerical  data given only apply to  the  Rouen region,.

FORECASTING  OF  HEAVY SMOG IN  OSAKA.   (Konodo
taiki osen no yoho). Text in Japanese. Taiki Osen Kenkyu (J.
Japan Soc. Air Pollution), S(l):106, 1970. (Proceedings of The
Japan Society of Air Pollution, Annual Meeting, llth, Tokyo,
Japan, 1970.)
Smog warnings are issued in Osaka at present after heavy pol-
lution becomes apparent and nothing effective can be done
toward its solution. Studies were conducted as to the accuracy
of early forecasting as well  as the characteristics of smog in
Osaka in order to permit anti-smog measures. According to the
past two-year records of forecasts made on the day before, ac-
curate results were obtained generally in fair weather when:
migratory high  pressure covered  the air and high pressure
stayed behind and the low  pressure approached from  the
Kyushu area. Predictions  were often  inaccurate  when:  the
protrusion  of high pressure was  weak; Osaka was  in  the
trough of pressures;  or when the cold front was approaching.
Accurate results can be obtained by the forecast made on the
same day on all items except the last. The prevailing two types
of smog are: a heavy smog in the morning and evening, caused
by weak pressure inclination and by the land and sea breeze in
the Osaka  Plane; and  day-time or morning smog caused by
rain or gradient winds growing strong during the previous
night.

Japan Society of Air Pollution, Annual Meeting, llth, Tokyo,

Broad-scale,  long-term weather and pollution forecasting is
necessary to  effectively prevent pollution. An  extremely early
prediction may not be possible, but a forewarning by at least
several days  of weather susceptible to heavy  smog  is desira-
ble. The weather and smog patterns of each industrial area are
different;  for instance, long waves of air circulation passing
near Japan seem to be closely connected with the pollution
and atmospheric stability of Kyoto during winter. A long-term
prediction is different from  a short-term one in which a pollu-
tant is assumed to diffuse endlessly into the atmosphere. The
purpose of broad-scale forecasting must take  in the possibili-
ties of the appearance of pollutants at the least expected geo-
graphic areas. A prediction covering about a month requires a
definition of types  of dispersion according to the weather and
types and  volumes  of daily pollutants. In a  study of at-
mospheric circulation, pollutants serve as tracers; further stu-
dies must be made concerning their roles in energy-balance
and absorption, reflection, and diffusion  of various radiation
by pollutants.

Data on smog conditions in London and Rotterdam are com-
pared,  and  the characteristics of  this phenomenon   are
discussed. During the London pollution disaster  of December
5-9, 1952, when  mortalities were about 4000 above  the normal
death rate, the blanket of smog was only 75 m  on the south
side of London and 120 m on the north side, with an altitude
of 45 m at Blackheath. The smokestacks of the power plant at
Battersea  were  above the  smog layer, and the plume  was
blown by an appreciable wind. The maximum diurnal smoke
concentration was 4500 micrograms, and  the sulfur dioxide
concentration was 3600 micrograms per cubic meter. During
the same period in Rotterdam, the fog  was also heavy,  but
SO2 measurements were not made, although there were com-
plaints of unpleasant odors to the Soil, Water and Air Com-
mission. Studies of mortality rates, in which cardiovascular
symptoms were treated separately, gave negative results when
compared with the previous month. Studies were also made of
the three-day smog incident that began January 29,  1959. Stu-
dies revealed an extremly stable atmospheric  condition,  SO2
readings of  650  micrograms  per cubic meter and  140 micro-
grams  of sulfuric acid. The maximum  smoke concentrations
for readings taken  every  hour were 500-550 micrograms.
Another weather condition  of  the  same  type  occurred on
December 5, 1962  over  Rotterdam. Sulfur dioxide measur-
ments in five cities varied between 1000 and 1500 micrograms,
while dust readings were between 400 and 450.  Simultaneous
SO2 readings in London,  Paris,  and even Milan were about
5000 micrograms per cubic  meter. In this case, a  study of
medical statistics indicated some increased mortality during
the smog epidemic; this was a little more evident when  only
the cardiovascular symptoms were considered. During the last
week of February 1970, unusual weather conditions occurred,
but no fog.  High SO2 readings were obtained at Rotterdam,
Vlaardingen, and Maassluis, but not  at  Amsterdam or The
Hauge. This problem is discussed from the standpoint of fuels
used in domestic heating and to power automotive vehicles,
with a recommendation for greater use of natural gas and bot-
tled gas, the latter both for heating and  for vehicles.

MOVEMENT  OF MINUTE PARTICLES OF  SMALL IN-

Meteorologicke Zpravy,  vol. 4:14-16,  1950. Translated from
Czech. Mundus Systems, Me Gregor and Werner, Washington,
D. C., 7p.
Certain types of mechanical turbulence are better suited to the
dissemination of passive  or semi-passive  particles into the at-
mosphere. A thermal turbulence is characterized by only mild
winds and clear weather, whereas a  mechanical turbulence is
characterized by strong wind over a broad vertical layer close
to the surface. The vertical and horizontal shpae and extent  of
a mechanical turbulence are dictated by the location and shape
of the obstacles encountered in the path of the air flow. With
their southeasterly slopes,  the  Krusne mountains are ideally
situated for  the formation of wave-type air flow activity, par-
ticularly with a good brisk  northwest wind. The possibility  of
greater deposits of particles and insects carried over from the
windward side is limited to areas of calm  because the areas  of
strong  surface  winds are more suitable  as departure  points
rather than landing points. The most  endangered region where
particles  would be  likely to land is the valley of the river
Ohre, which is  where a permanent and virulent concentration
of the potato blight has been observed.

A simple method is described with which the local distribution
of a dust suspension in a  laminar air stream can be deter-
mined. After passing an obstacle  or through a temperature  or
diffusion field,  the  dust is  collected  on a membrane filter on
which an image of  the obstacle around which flow occurs is
produced. An example of a thermal field is provided to show
that the new method is suitable for quantitative investigations.

The direct and indirect influence of various climatic factors on
emissions are discussed on the basis of  air quality measure-
ments made in  biege, Belgium, and  its suburbs in  1958-1959.
The average differences between the hot and cold  seasons pro-
vide an  objective assessment of the amount of pollution from
industrial and  urban causes. For certain pollutants, such  as
carcinogenic poly cyclic  hydrocarbons,  the  differences are
highly pronounced.  The daily concentrations of the pollutants
and their correlation with climatic conditions indicate the basic
importance of meteorologic and topographic factors in disper-
sion. These  facts indicate important  approaches to  abatement
planning, and particularly  to the  development of forecasting
and emergency  systems. Certain forms of pollution are directly
associated with population density. The wide  dispersion area
of industrial effluents is  defined and the  role of green spaces
in the Liege area is assessed on a  quantative basis.

                         ide  concentrations  in urban areas is  described. The computer
                         input consists of  data  from an emission  source  inventory
                         together  with statistics on  relevant  diffusion  parameters.
                         Because of the capacity of available computers, only a limited
                         number of the largest  emission  sources  can be treated in-
                         dividually. Smaller industrial emission sources are treated as
                         residential sources.  These are represented by a large number
                         of stacks  of  the same  dimensions for which the mean  area
                         emissions  have been estimated.  The meteorological input  con-
                         sists of data on wind direction,  wind speed, and stability. The
                         program also  uses corresponding statistics for urban boundary
                         layer depths and values  for parameters affecting absorption at
                         the  earth  s  surface. The diffusion  model used  is  basically
                         Gaussian.  It is modified, however, such that turbulent diffu-
                         sion is restricted exclusively to the depth of the urban bounda-
                         ry layer. The  rate of decay  of sulfur  dioxide  is also taken into
                         account. The model calculates  fields of steady-state ground-
                         level concentrations that correspond to a given spatial distribu-
                         tion of emission sources and to any possible combination of
                         relevant meteorological diffusion parameters. Knowledge of
                         frequency  distributions  of these   meteorological   diffusion
                         parameters permits the derivation of frequency distributions of
                         ground-level concentrations for  any location  within or outside
                         of the  metropolitan  area. The computerized experiments simu-
                         late frequency distributions of ground-level concentrations for
                         a great number of regularly arranged grid points  (up to  2500
                         with a mesh  size of 500 by 500 meters) and for a variety of
                         time periods (months, heating period, seasons of year). Experi-
                         ments to validate the model were conducted during the heating
                         period in  1967-68 at four continuous monitoring stations that
                         had been installed at special locations within the limits of the
                         metropolitan area of Bremen. (Author abstract)

                         The relationship  between meteorological factors and air pollu-
                         tion is investigated. With periods of atmospheric  stability, an
                         inversion stratum acts as a  cover and retains the pollution un-
                         derneath, causing heavy smogs.  Inversions in Japan occur dur-
                         ing  the winter, in periods of rain fronts or migratory pressure,
                         and with wind velocity of less than 3  m.  Stacks high enough to
                         break  through the inversion strata would enable  the emitted
                         pollutant  to  dilute before  reaching the environmental at-
                         mosphere. The height of the inversion strata, however, cannot
                         be accurately measured  and the pattern of diffusion in the un-
                         stable  air above  the strata is unknown. Weather and  pollution
                         forecasting demand accurate data. Present smog warnings are
                         issued too late, do not  enforce the elimination of pollutants,
                         and affect only the use of low-sulfur content  fuels.

The dusty haze above  the  river network of  the western Tien
Shan  at altitudes ranging between 100 and  1500 m and 1500
and 3000 m  was explored by means of 17 helicopter expendi-
tions  performed  during the July and August months of 1964.
The haze distribution over  the investigated region was graphi-
cally illustrated. The most intense turbidity was observed over
the city of  Tashkent.  This turbidity  was referred  to  as the
aerosol lens  because of its specific shape. The natural origin of
this haze appeared to be combined with the industrial aerosols
produced  in  the urban area of Tashkent. Local transfer of
haze due to mountain  and  valley air currents were  seen. The
Northern and North-Western regions  of  the valley  were less
dusty than those of the South or South-Western regions. Both
local and incoming haze stagnated within the lower 2-3 km al-
titude  above  the  Fergana  Valley due  to the  weakness of
summer winds.

THE  ROLL OF  METEOROLOGY IN THE  PRESERVATION
OF  THE  CLEANLINESS OF  THE   ATMOSPHERE.  (A
meteorologia  szerepe a levegotisztasag vedclmeben). Text in
Hungarian. Idojaras (Budapest), vol. 74:513-530, 1970. 20 rets.
The most important role of meteorology in air pollution con-
trol work is  the prediction of  the frequency  and amount of
ground level emissions. Inventories of emission sources and a
turbulent diffusion model are used on digital computers to pro-
vide three dimensional  flow and temperature distributions and
their variations as a function of time. The model  uses a year s
observed data. Input data includes the wind profile  (based on
five  years),  the  stability  (based on eight years),  and the
thickness of the  mixing layer. A first approximation of the air
pollution  model for Budapest  was  calculated  in  1969-1970
using the  theoretical and experimental values. Peak values of
two to twelve times the allowable norm were  found in the
inner  city of Budapest for sulfur oxides, chlorides, nitrogen
oxides, settling  dust,  and  smoke. Predictions regarding the
planned expansion of the Danube Thermal Power Station were
presented; the influence of  different stack geometries were ex-
plored. During the next few years, smog predictions will be
made  for Budapest.

EXTRAORDINARY  CARBON   MONOXIDE  CONCENTRA-
TIONS IN THE  AIR OF MAJOR CITIES.  (Aussergewoehn-
liche  Kohlenmonoxid-Konzentrationen in Grosstadtluft). Text
in German. Bundesgesundheitsblatt, 13(5):59-62, 1970. 10 refs.
During a  10-month period of  continuous air pollution in a
lightly-traveled street 3 km from  the center of Berlin, the
median half-hour carbon  monoxide level of  8 ppm  rose sud-
denly on Dec. 9, 1969 to very high levels,  characterized by
two peaks of 23  ppm. This high lasted  for nine hours.  The
simultaneous half-hour  SO2 concentration was 1.03 mg/cu m
and the median three-hour  dust fall was 0.47  mg/cu m. This
episode coincided with the advent of a  cold arctic air mass
over Germany which spread over Berlin  on December 9 and
brought  all  air  movement to  a  standstill.  This  extreme
phenomenon  indicates that under conditions of weather inver-
sion emission clouds can form, possibly with their own circu-
lation in which  condensation  processes  and  irradiation may
play a  stabilizing role.  Under such  circumstances, the at-
mosphere itself can erect barriers leading  to a local accumula-
tion of  pollutants which otherwise are formed only by topo-
graphic  interactions.

1967. 23 refs.
A tentative analysis of the climatic conditions of the city of
Tbilisi and its surrounding areas  is presented. Temperature,
humidity, wind,  sunshine and fog are being considered among
the main meteorological factors affecting the air pollution of
the city. The inversion phenomena developing in  the lower
section  of the city, which is part of the Kura valley, lead to a
weakening  of the exchange processes and preclude the effects
of turbulence on the ventilation of the city. Humidity affects
the microclimatic condition of the  city in that the existence of
suspended  dust  particles (due  to poor road conditions) in its
air constitute the condensation nuclei for the formation of fog.
Fogs are formed under conditons of 90% humidity,  whereby a
considerable  increase in industrial  waste gas concentrations in
observed. Haze  is considered to be the most  specific fog for
Tbilisi and is therefore being used as an indirect parameter in
the assessment of the  air pollution of the city. Rainfall and
ventilation  are considered  to  be  the meteorological  factors
determining the removal of aerosols. Both, however, are com-
promised by long periods  of lack of precipitation, ranging
between 30-60 days during the summer or winter season and
by the orographic features  of the city. A program  of intense
research in the fight of air  pollution due to local factors such
as coal  heating,  industrial pollution, poor road conditions and
waste accumulations from building activities, is recommended.
It includes problems  such as the sources of pollution, the
chemical composition of aerosols, the admissible standards of
pollution, the effect of  aerosols on the biological and corrosive
processes and  the role of pollution for further  urbanistic
developments of the city.

DISPERSION OF  POLLUTANTS  AND  THE  MICROCLI-
MATE AT  LACQ.  (Dispersion des polluants et microclimat a
Lacq). Text in French.  Ann. Mines (Paris), no. 11:21-30, Nov.
1970.
The natural gas discovered at Lacq in 1951 and exploited since
1956 is a mixture of hydrocarbons, CO2, and water vapor con-
taining 15% hydrogen sulfide. Waste gas  emitted into the at-
mosphere from the desulfurization of this gas and by-product
recovery of sulfur  contains 0.6% SO2, which under  certain
meteorological conditions causes widespread damage to feed
crops,  viticulture, and orchards  surrounding Lacq. It was
found that not the prevailing SO2 pollution level but rather the
coincidence of several meteorological conditions characterized
the days on  which damage occurred.  By  analyzing tempera-
ture, humidity, wind direction and velocity, precipitation, and
insolation and by correlating their levels  with  the  damage to
vegetation  on certain days, criteria were defined  which are
helpful  in  forecasting  weather  conditions  likely  to  cause

damage to crops. When such conditions occur (fog, haze, in-
version), an  advisory is issued by the Regional Meteorological
Center at Bordeaux to the station at  Lagor which in turn ad-
vises  the plant at Lacq. The plant then reduces operations
temporarily to minimize damage to crops.

By  a  method of principal component analysis based  on cor-
relations  between five air pollutants (dust, sulfur dioxide, car-
bon monoxide, nitric oxide, and nitrogen dioxide), an air pollu-
tion index was calculated and a relation was obtained between
air pollutant concentration and air pressure distributions.  In
winter, air pollutant concentrations gradually increase when an
anticyclonic  movement is followed by a cyclone passing over
Japan.

Concentrations of beryllium(7), phosphorus(32), and sulfur(35)
in surface air and in fallout were sampled by filter at a Lenin-
grad station for four  years  from 1963  to  1966. Radioisotope
concentrations varied with the season, reaching a maximum at
the end  of  May and a minimum  in  October of each year.
These patterns changed, however, with increasing precipitation
or intensified deposits of cosmogenic radioisotopes from the
stratosphere. S(35) fallout in 1963 included a sizable contribu-
tion  from  experimental explosions. Both S(35) and  Be(7)
showed a high correlation with theoretical estimates of mean
annual fallout based on the  rate of formation of cosmogenic
radioisotopes during periods  of minimal solar activity. A sharp
deviation from the theoretical was  observed for P(32). An
analytical formula was derived for the annual course of the
three  cosmogenic radioisotopes in surface air and a curve was
obtained  showing  the  boundary  between  the  interval  of
decrease and  the  interval  of  increase  of concentration.
Matching of stratospheric replenishments of concentrations
against synoptic  special features showed that altitude cyclones
are one of the fundamental causes for the penetration of sig-
nificant masses of stratospheric air.

ON THE GROWTH OF DROPLETS BY CONDENSATION ON
HYGROSCOPIC NUCLEI. Tr. Inst. Eksp. Meteorol., no. 6:16-
96, 1969. 9 refs. Translated from Russian by C. Long, National
Lending Library for Science  and Technology (England), 7p.
Numerical calculations made so far do not give a detailed pic-
ture of the  growth of small particles since they take no ac-
count of factors  such as the structure of a nucleus  and the
amount of soluble matter in it. Because these factors are im-
portant in the study of the condensation stage in the develop-
                        ment of cloud spectra, detailed calculations were made on the
                        basis of an equation describing the growth of droplets by con-
                        densation on hygroscopic nuclei. The results  show that the
                        growth of droplets on hygroscopic nuclei  is appreciable even
                        at humidities of 80-90% and that very small changes in relative
                        humidity can play a significant role in the subsequent growth
                        by condensation of nuclei from 0.5-one micron.  Even when the
                        necessary conditions for cloud or fog formation are absent,
                        nuclei can increase their  radii by a factor of two or three and
                        produce great changes in atmospheric optical properties. If hu-
                        midity departs by 0.01% from 100%, growth of 0.5-one micron
                        particles may either cease because the equilibrium radius is
                        reached or may continue indefinitely.

                        Atmospheric stability is essentially a function of temperature,
                        relative humidity,  and air movements.  Static  thermal inver-
                        sions arise from a compression of the air masses at 600-1500
                        meters, while radiation inversions which  can  form at lower
                        levels are more important with regard  to pollution. In order to
                        evaluate atmospheric stability, the entire  day  may be  subdi-
                        vided into four quadrants: night hours, sunset or sunrise, four
                        hours after  sunrise or sunset, and noon. The quadrants are as-
                        signed coefficients of zero,  one, two, and three respectively.
                        Next, the factors deriving mainly from the hygrometic state of
                        the  air are characterized by visibility and cloudiness, also with
                        coefficients ranging from zero to three. The hygrometric state
                        of the ground is defined as frozen (zero),  wet  (one), moist (t-
                        wo), and dry (three). The wind can be defined with velocities
                        less than or equal to two m/sec, one  m/sec, eight ml sec, and
                         16 m/sec, with coefficients  from zero to  three, respectively.
                        By  adding up the final coefficients, the atmospheric stability
                        conditions may be deduced:  between zero  and  four, inversion;

During the winter of 1970, high pollutant concentrations lasting

during these periods were examined  with respect to the pres-

hemisphere were analyzed in  comparison with  the weather
map on the ground surface. The variation in sulfur oxides con-
centration,  wind direction  and speed,  and the amount of in-
solation during these three days are also shown by a diagram.

The high atmospheric pollutant concentration  is often  as-
sociated with the atmospheric stagnation causing the pollutant
accumulation. Based on meteorological data and sulfur oxides
concentration  recorded  in  Osaka  City,  the  relationship
between the atmospheric purification effect and meteorological
conditions was quantified by classifying  atmospheric pressure
distribution patterns into eight types. The derivation of mathe-
matical equations for the purification effect as functions of
wind and time is discussed.

The prediction of pollutant concentration is made based on the
amount of pollutant released into the  atmosphere, meteorologi-
cal  factors, and  topographical factors. The prediction  model
based on the meteorological factors is discussed. The necessa-
ry conditions for this model are that the change  in pollutant
concentration is  dependent  on the  concentration at a certain
prior  time, and  that corrections are made with  changes in
meteorological  factors.  The  statistical   prediction  formula
which satisfies these condition is used for the prediction. The
meteorological factors are relative  humidity, wind  direction,
wind speed, visibility, atmospheric pressure, and temperature.

According to the wind diagram of Kyoto basin indicating the
wind  speed and  direction at different times of the day, rela-
tively strong north-western wind is  dominant in the afternoon
while milder morning wind is mostly southemly. To investigate
the effect of Osaka City on the air  pollution in  Kyoto, the
change in sulfur dioxide concentration with time  at six loca-
tions between Osaka and Kyoto city was  measured during the
period of Jan. 11 to 13, 1971. The SO2 concentration peak was
shifted  from Osaka toward Kyoto as the  time  of the  day
progressed. The geographical distribution  map of SO2 concen-
tration measured at two hour intervals indicates that the SO2
concentration  is the  highest in Osaka  in  the  morning,  in
Yahata area in the afternoon, and in Kyoto city in the evening.
However, the mode of pollutant migration is not clarified.

The effect of particulate matter on the catalytic oxidation of
sulfur dioxide in the atmosphere was studied by oxidation ex-
periments. A glass fiber filter with particulate matter collected
using a high-volume air sampler at various stations in Japan
was immersed in distilled  water, and a gas containing 10 ppm
of SO2 was passed through at the  flow  rate of 3.5 1/min for
one  hour.  A  definite correlation  was  found between  the
amount oxidized and the  concentration  of some particulate
matter;  the  correlation coefficient for sulfate equals  0.778;
vanadium, 0.747; manganese,  0.667.  The correlation coeffi-
cients of cadmium, lead, zinc, iron, and copper were extreme-
ly small.

The physics of gaseous  ions and submicroscopic suspensions
are reviewed from the standpoint of laboratory and field ex-
perience. Normal and other ionization processes and the mo-
bility, adsorption,  diffusion, and recombination  of ions are
discussed. Processes occurring  in an ionized gas under the in-
fluence  of  an externally applied electric field are indicated.
Current-voltage characteristics and  the electrode effect are
considered. The motion  of ions is noted and the phenomenon
of  nonselfsustaining  discharge  at  reduced  pressure  is
discussed. Luminescent phenomena are described. Charge car-
riers,  types of  discharge, and ignition are discussed for self-

                         The dilution of emissions depends on the wind and on the tem-
                         perature layering. The pollution in the immediate vicinity of a
                         pollution source is higher during weaker winds. With stronger
                         winds the pollutants are carried to more distant areas, so that
                         lower concentrations are found in the immediate vicinity. With
                         high temperature lapse rates,  e.g., 1 C per 100 m height, the
                         turbulence is high and the pollutants are carried to  higher al-
                         titudes by intense vertical exchange. The lowest vertical pollu-
                         tant transport occurs during temperature inversions. An illus-
                         tration  of  plume behavior during various temperature  lapse
                         rates and at inversion is given. The knowledge  of meteorologi-
                         cal conditions for air exchange is important in two fields, for
                         the  smog alert service and for the creation of master plans for
                         industrial  centers  and  residential  areas.  In  the  Federal
                         Republic of Germany all meteorological parameters  which are
                         important for evaluation  of  the  degree  of pollution  on the
                         ground level are monitored by the Deutschen Wetterdienst.
                         Various  states  of the Federal Republic  of Germany  have a
                         smog alert service. North Rhine Westphalia has provided such
                         service ever since April 1964. It is important to know the ven-
                         tilation conditions prior to the creation of master plans. This
                         knowledge helps to prevent the erection of a  new residential
                         section on the leeward side of  an emission source.

AN INVESTIGATION OF THE COMBUSTION PRODUCTS
OF ALKYL-LEAD COMPOUNDS.  NNZur Kenntnis der Ver-
brennungsprodukte von  Alkylbleiverbindungen.))  Brennstoff-
Chem. Essen 47(9) 280-5, Sept. 1966. Ger.
Tetramethyl-, tetraethyl-, and tetra-n-propyl lead were burned
in air in the presence of n-n-heptane, isooctane, or benzene.
The combustion products were collected on the surface of a
cooled glass tube, in a glass wool filter, and in an electrofilter.
In order to eliminate the formation of nitrites, the nitrogen in
the air could be  replaced  by argon. The combustion of the
alkyl lead  compounds takes place  as follows: the  compounds
thermolyze when  the combustible mixture approaches the hot
regions of the flame. The result is  a smoke of fine PbO parti-
cles. The  combustion residues are then  almost identical to
those from the alkyl lead  mixture. In the third zone, behind
the flame, PbCO3(52-86%), PbO(13-45%), Pb02 (as Pb304, etc.
0.1-3%), and Pb(N02)2 is formed.  In internal combustion en-
gines  the  effectiveness of PbO as an antiknock  agent lasts
about 1  millisecond. These experiments suggest that the  sur-
faces of the PbO  particles  may convert  to Pb(NO2)2, thereby
rendering the antiknock additive ineffective.

A METHOD FOR SAMPLING AND DETERMINING HEAVY
HYDROCARBONS IN COMBUSTION  FUMES.   (Mise  au
point d'une  methode de  prelevement  et de dosage  des
hydrocarbures lourds dans  les fumees de combustion.) Text in
French. Ann. Mines Belg. n(3):309-331, March, 1968. 16 refs.
A method  has been devised for sampling and measuring heavy
hydrocarbons in combustion smokes. The sampling technique
is based on the adsorption  of the hydrocarbons on a short ad-
sorbent column placed within the chimney itself. The smokes
can be drawn up  through  the sampling tube in  less than one
minute with the help  of a rubber syringe. In order to measure
the hydrocarbons  collected, the sampling tube is inserted in a
carrier gas circuit  which also includes a flame ionization detec-
tor. The tube is brought up to a high temperature  in a mobile
oven. The  hydrocarbons are desorbed and carried by the carri-
er gas towards  the  dector; there is  no  separation  of the
hydrocarbons and the response appears in the form of a single
peak on the recording paper. It is possible to desorb hydrocar-
bons having a boiling point above 500 degrees  C  without in-
ducing cracking phenomena. The  output, which depends on
the boiling temperatures  of the sampled hydrocarbons, is ex-
cellent and  can  be  still  further improved if,  prior to  the
sampling,  the tube  is  refrigerated.  A  quantity of  10-6g
anthracene produces  a peak allowing  accurate quantitative
determination of the compound. The method also makes possi-
ble to perform a detailed analysis of the sample and determine
the individual concentrations of the various components. For
this purpose, a chromatographic column  must  be inserted into
the carrier gas, between the sampling tube and the detector.
Several examples  of the determination of total and individual
concentrations in  various synthetic gas  mixtures,  combusion
smokes, cigarette smoke, automobile exhaust, are presented.
The possibility of applying the method to the measurement of
benzo(a)pyrene  is being considered. Another method for as-
sessing the sample by methanol elution followed by a spec-
trophotometric examination is also described.

Self-ventilation of rooms as a function of outside wind condi-
tions was  investigated with an  attempt to distinguish ventila-
tion through pores from air exchange through cracks around
doors, windows, and in the floor. The affect of wind  direction
and inside-outside temperature difference on the volumetric air
exchange were estimated. Decreases, with time, of experimen-
tally established levels  of  water vapor, carbon dioxide, and
aerosols in the rooms were measured. Complete exchange of
the entire  air volume of a standard room in one hour (ventila-
tion coefficient equal to 1.0) required a wind velocity of  6-7
m/sec, a value which rarely occurs in cities. An average ven-
tilation coefficient of 0.46 was obtained in carbon dioxide stu-
dies. Dependence of self-ventilation on wind direction could
not be established. It is concluded that wind velocity is deci-
sive in air for rooms on higher floors, but is negligible  for
basement  and  ground-floor rooms where inside-outside tem-
perature is the determining factor. Naturally, these two factors
overlap at intermediate heights.

An investigation is described  of  the  variables which may
produce changes in brain-wave  patterns on  electroencephalo-
grams (EEC) during mental activity and  periods of  selective
attention in humans. The EEG's of the precentro-central (PC)
and  occipito-  temporal  (OT)  areas  were  recorded with
telemetry, and their changes during six standardised visuomo-
tor and two cognitive tasks were compared with the EEC dur-
ing rest with open eyes. Automatic EEC analysis on  the prin-
ciple of zero-crossing and  interval analysis was  used.  The
EEG changes during tasks differed significantly in the PC and
OT areas,  and showed a dependence both on individual factors
(type of resting EEG with the eyes open) and on the charac-
teristics of the tasks. On the other hand, they were not corre-

the performance of each task. Detailed data analysis produced
evidence of a differentiation between EEC reactions to dif-
ferent tasks. The PC alpha-rate showed the least decrease dur-
ing cognitive  tasks, while the  OT  alpha-rate  showed the
highest tendency towards activation during maze drawing with
direct or mirror image control.  The  occipital beta-activation
was lowest during writing without visual control. (Author ab-

SULFUR  PRODUCTION   FROM HYDROGEN   SULFIDE
WITH THE CLAUS PROCESS.   (Gewinnung von Schwefel
aus Schwefelwasserstoff nach dem Claus-Verfahren). Text in
German. Chem. Ing. Tech., 41(1-2): 1-7, Jan. 17, 1969. 9 refs.
About 92 to 94% of sulfur is obtained  from the H2S of natural
gas by the Claus process.  The  remaining 6  to 8% sulfur is
presently emitted with the waste gas  as SO2. With the  strin-
gent air  pollution control laws which are now being introduced
in all industrial countries, it becomes necessary to increase the
sulfur  output  to  97%.  Computation  of  the  dissociation
equilibria in the sulfur vapor of the Claus process showed that
higher outputs can be achieved  if the gas is  cooled to about
220 C prior to entering the  first  Claus reactor. If the reaction
gas contains  COS  and  CS2,  these compounds must  be
hydrolyzed in the first contact process. As a consequence, the
temperature in the feactor increases. With a hydrogen sulfide
content  of 70% by volume,  the theoretical sulfur output at the
first contact process would be  91%. To obtain an optimum
output, the second contact process must then take place at the
lowest possible temperature. The proper input temperature at
the second Claus reactor was found to  be 187 C.  Waste gas
from the second reactor is freed from the remaining elementa-
ry sulfur in a scrubber operated with liquid sulfur at 120 C and
goes to  an  afterburner,  where the remaining H2S is converted
to SO2.  It  is theoretically and practically possible  to increase
the sulfur output of the Claus contact process to 97% by the
use of a highly active alumina catalyst so that  the SO2 concen-
tration in  the waste gas is less  than 0.5%  by volume. By
further decreasing the operating temperature in the Claus reac-
tors, better results could be achieved, although this is not ad-
visable in the presence of CO2. Prerequisite to such a success-
ful operation is the exact  adjustment  of  the stoichiometric
amount  of primary air in the combustion chamber.

A STUDY  OF THE ABSORPTION OF SO2  IN  WATER BY
LIQUID JET.  Translated from Japanese. (Source  Unknown),
p. 41-45, July 4, 1968
The diffusion coefficient of SO2 has been  measured  at 30
degrees  C by using a liquid  jet out of a bell-shaped  nozzle. Six
glass nozzles were used with pore sizes between 0.11 and 0.06
cm in diameter. The liquid jet was about 2 cm long- and was hi
contact  with SO2 gas from  2.9 times  10 to  the minui 3 to 1.7
times 10 to the minus 2 sec. The amount of absorbed SO2 was
determined  by potentiometric  titration with  KMnO2 under
slightly  alkaline conditions.  The  actual value  agrees well with
those values calculated using Scheible's formula.

                        The use of fluidized bed incineration is limited, among other

An attempt was made to explain the catalytic oxidation of sul-
fur dioxide on the basis of a theory proposed by O. K. Dav-
tyan.  The following catalysts were studied:  spongy  platinum
applied to porous phosphorus through reduction from a solu-
tion of chloroplatinic acid, activated charcoal, vanadium pen-
toxide obtained by coagulation of  a  colloidal solution in the
form  of a powder (without carrier), powdered graphite, pow-
dered chromium trioxide, and powdered ferric oxide  (listed in
order of  decreasing activity). In all cases, chemisorption was
found to  proceed with sufficiently high rate at room  tempera-
ture, the  oxidation products being readily removed as sulfuric
acid by washing  with water.  Curves of total adsorption and
chemisorption rates as a function of time were plotted. It is
noted that the presence of water vapor on the catalyst surface
usually increases the maximum  quantity of oxidized sulfur
dioxide.

Considerations necessary for a better theoretical and practical
understanding of chromatographic separation of hydrocarbons
are presented.  Topics  examined  are: absorption energy  of
hydrocarbons on graphitized carbon black and magnesium ox-
ide; absorption energy of hydrocarbons on hydroxides; adsorp-
tion isotherms for individual hydrocarbons on a uniform sur-
face;  effect of chemical modification of  absorbent surface on
the absorption of hydrocarbons; effect of geometrical modifi-
cation of absorbents-creation and alteration of surface—on the
absorption of hydrocarbons. It is recommended that further
work  center  on  the following  items:  theory  of adsorption
forces, calculation of adsorption energy,  measurement of heat
of adsorption at  different temperatures; statistical theory  of
adsorption equilibria, measurement of heat capacity of adsorp-
tion systems; investigation of the  state of surface  chemical
compounds and adsorption complexes using infrared spectra
and other new methods; investigation of the geometric struc-
ture of adsorbents and structure modification; investigation  of
the chemical structure of surfaces and their chemical modifica-
tion;  investigation of adsorption equilibria for gas fixtures,
especially by  the vacuum circulation method  using new adsor-
bents.

OBSERVATIONS ON THE THEORY OF JET IMP ACTORS.
(Bemerkungen zur Theorie der  Duesen-impaktoren). Text  in
German.  Atmos. Environ., 3(l):69-83,  1969. 15 refs.
The familiar theory of jet impactors is valid only for  spherical
particles  at low Reynolds  numbers. Exact application of this
theory to non-spherical particles in jet impactors is not possi-
ble. Therefore, the impactor theory was  modified and is now
based on the  equation of motion of non-spherical particles  at
conditions occurring in jet impactors.  Aerodynamic drag coef-
ficients and form factors of a number of particle  shapes are
discussed. These  factors,  together with their variation with
Reynold's and Mach's numbers, are contained in a special in-
ertia coefficient. It is shown how the collection efficiencies of
impactors are calculated from the solution of the equation of
motion of particles.  It is possible now to  explain  the  dif-
ferences between the impactor calibrations of Ranz and Wong
and of Stem et al. Calculations  on the  influence of particle
shape and density on the impaction process show that jet im-
pactors and other sampling instruments based upon the inertia
principle are not capable of measuring the size and the number
of atmospheric aerosol particles in absolute terms.

Fifteen male rabbits aged 6  to 12  months received daily in-
travenous doses  of 3.5 mg manganese as  1% MnC12 in 0.15 M
NaCl solution for up to 32 days. Symptoms began  to appear
after the first week. The animals became excited and aggres-
sive. This stage was followed by apathy and refusal  to eat. At
the end of the  intoxication period, tremors of the  head and
legs were observed in  two rabbits, two  had equilibrium dif-
ficulties, one salivated, and three had died. All animals  were
decapitated, including the five control animals. One hour after
death, tissue samples were taken  from the liver, spleen,  lung,
kidneys,  large intestines, pancreas, adrenal  glands, and the
scrotum. Pathomorphological changes were found in  all or-
gans. They were filled with blood and hyaline thrombosis was
diagnosed. The  largest  changes  were  found   in  the  liver
parenchyma. Various degrees of decay to  necrosis were found,
accompanied by  inflammation.  The microscopic pictures
looked similar to acute liver cirrhosis. The kidney and the
large intestines  were the  least damaged organs. Degeneration
of the nephrons and inflammation of the mucous membrane
were seen. The toxicity of manganese to several organs can be
explained by its toxic effect on the central nervous system and
on the blood vessels.

In the production of chloride  (C12) by oxidizing KC1 and S, the
addition of pyrite  (FeS2) increased the  reaction velocity by
maintaining a high temperature;  it also  increased the sulfur
source as  FeS2  and produced Fe3(SO4)3  as a catalyzer to ox-
idize SO2. The pyrite included 42.4% Fe and 42.9% S. The
KCL  and S were placed in a quartz cylinder, the internal
volume of which was 212 cu cm, and oxygen gas was sent into
this cylinder to  oxidize materials,  after  which the materials
were heated by  an electric hearth at 500 to 800 C. The higher
temperature showed larger  reaction velocity  (the reaction
velocity at 700 C was twice as much as that at  500 C). There
was little influence of the particle sizes of KC1 and FeS2 on
the production of C12. The reaction increased rapidly between
70 to 100 minutes after  it began.  The amount of sulfur to
produce C12 was maximum  when  the weight ratio between
pyrite and S was one to one, and it increased with the  small
amount  of material compound when the  compound had  a
definite  weight  ratio of KC1, S, and pyrite. Eventually the
production ratio of C12 from KC1 was  55  to 80% when the
weight ratio of pyrite to KC1  was  10 to 30%, the reaction tem-
perature was 600 to 700 C, and the reaction time was 2 to 3

ABSORPTION OF SULFUR DIOXIDE,  p. 241-250, 1964 (?) 16
refs. Translated from Japanese. Franklin Inst. Research Labs.,
Philadelphia, Pa., Science Info. Services, 15p., July 1969.
The measurement of the rate of sulfur dioxide absorption into
a laminar jet was performed to investigate the effect of chemi-
cal reaction between SO2 and OH(-) in liquid phase on the rate
of SO2 absorption from gas phase, and also the mechanism of
chemical reaction between SO2 and  OH(-) in  liquid phase.
Flow in the jet was shown to be uniform and parallel with the
axis, with absorption  taking place according to the basic equa-
tion of diffusion. The effect of chemical reaction on  the rate
of gas  absorption was expressed by the following equation:
beta yields 1 plus 0.88q(1.2), where beta is the ratio  of mass
transfer coefficient accompanied by chemical reaction to the
coefficient without it,  and q, the ratio of the initial concentra-
tion of OH(-)  to the  saturated concentration of SO2  in solu-
tion. This formula greatly resembles  the theoretical equation,
derived under the assumption of instantaneous irreversible
second-order reaction, except for a slight difference in the
power  of  q. It is therefore concluded that within the present
time range of contact  time, SO2 is absorbed into NaOH aque-
ous solution with instantaneous irreversible second-order reac-
tion, and  that the effect of the chemical reaction on the ab-
sorption velocity is expressed by the equation given above.

TESTS ON FORMATION OF FECL2 AND FECL3 BY REAC-

The reaction of  hydrogen chloride containing gases with pul-
verized Fe, Fe304, and Fe203 was studied with respect to tem-
perature. Moreover, the influence of water  vapor and oxygen
in the  HC1- containing  gases on  the  faction with the above
mentioned substances was studied with respect to temperature.
For each experiment,  0.3 g of  the pulverized substances were
heated in the presence  of pure  nitrogen. Each experiment
lasted 4 hours. The HC1- containing gas (100 cu cm/min) was
passed with a speed of 0.44  cm/sec through  the  reaction
chamber at a temperature of 22 C. The reaction products were
cooled to room  temperature  and the weight changes of the
substances were determined. The reaction of Fe203  with N2
containing 5% by volume HC1 forms FeC13. The fraction of
solid FeC13  decreases with increasing temperatures while the
volatile FeC13 increases  with the temperature. Below 320 C,
volatile and  solid FeC13 are formed. The reaction of Fe with
the gas forms FeC12.  Above 670 C, no solid FeC12 is found.
Above 580 C, FeC12  is  increasingly sublimated. The  reaction
with Fe304  forms FeC12 and  FeC13. The  former  develops
primarily at  low  temperatures. The maximum FeC12 formation
takes place between 200  and 250 C. The FeC13 is sublimated at
300 C. The  reaction  of  Fe304 with N2 containing 10% H2O
and 5% HC1 forms solid FeC12 up to 550 C. No reaction takes
place between 550 and 700 C. Above 300  C, FeC13 and FeC12
form which are  immediately converted to Fe203 through the
influence  of water vapor. The  reaction with Fe forms  no
Fe203 only Fe304. Oxygen in  the gas like the water vapor im-
                         pairs the  HC1  reaction  with  Fe, Fe203,  and  Fe304.  The
                         presence of water vapor in addition to HC1 form volatile and
                         non-volatile chlorides but to a much lesser extend than in the
                         presence  of  HC1  alone  in  the gas. Oxygen further reduces
                         chloride formation.

                         A method permitting deliberate chemiluminescence from the
                         application of singular oxygen was studied and the intensity
                         was used for spectral analysis. The decomposition of hydrogen
                         peroxide by  hypochlorite liberates  molecules of singular ox-
                         ygen which  are characterized by  remarkable  spectroscopic
                         properties  and by  chemiluminescent  emission. The  chemilu-
                         minescence indicates the involvement of oxygen during reac-
                         tions in which it appears accidentally. The technical aspect of
                         chemiluminescence was  discussed. To influence the kinetics
                         and intensity of luminescence, the transition complex  X-O2
                         was stabilized by  cold. Hydrogen peroxide  decomposition on
                         FMN (flavine mononucleotide) was carried out  at 20 C. The
                         graph contained two curves which were obtained by tempera-
                         ture  variations between  0-35 C. The emissions were induced
                         after some waiting time at 0 C amounting up to 25-30 minutes.
                         During  this  period,   a  progressive  inhibition  of   FMN
                         fluorescence was recorded. After a  second experiment  in
                         which H2O2 and luminol were mixed, a lightning of chemilu-
                         minescence at 0 C and  an emission which produced heating
                         and decomposition of the transition oxide was observed. Using
                         interference  filters,  two  consecutive  emissions containing
                         radiations  centered at 6335 A and at 4350 A were observed.
                         An improvement of the sensitivity and specificity of the spec-
                         tral analysis is necessary for possible evaluation of the percent
                         of both radiations emitted in the two cases.

                         Various solid fuel combustion experiments were  conducted on
                         commercial scale experimental combustion equipment for the
                         purpose of application of low grade fuels.  Hokusyo coal and
                         other fuels were chosen  for sample fuels. The development of
                         new combustion  mechanisms by  aerodynamical and  ther-
                         modynamical principles  of fluidized reactions were explored.
                         The. method  is very useful as a combustion process for burn-
                         ing the high ash contents and the low generation of heat (about
                         2500 kcal/kg) of low grade coal.  Even the hard coal and the
                         stone abandoned in coal selection can be  used as  the  fuel.
                         Fairly crude  coal can be used; thus, it is possible to adjust the
                         micro-coal machine to a small size and to decrease the installa-
                         tion, operation, arid maintenance costs.  The micro particle
                         combustion  section in  the upper part of the combustion
                         chamber  and  the  fluidized combustion  in the lower  part
                         proceeds  concomitantly, makes  the combustion stable, and
                         enables  the  control  of change  of loss of heat.  With this
                         method, large amounts of micro particles produced at the coal
                         selection may be used without passing the micro  coal machine.
                         Good results were obtained for several experiments. (Author

The combustion of a single drop of liquid fuel in a sound field
is analyzed theoretically. Because of the influence of chemical
reactions  of  combustion  and  of  the  transverse flow  of
evaporating  fuel  vapors,  the  process  is much more  com-
plicated than that of 'pure'  mass transfer between a medium
and a  sphere. An approximate method for calculating com-
bustion rates is proposed. The method is valid, provided that
certain restrictions are imposed on  the values of the dimen-
sionless complexes characterizing the process. The dimension-
less evaporation rate is  shown  to depend linearly on the am-
plitude of particle velocity of the medium and to be inversely
proportional to the square root  from the frequency of oscilla-
tions. A formula is derived which relates combustion rates to
the sound oscillation  parameters and to the  intensity  of the
transverse flow of evaporating vapors.

COMPOUNDS.  (Verfahren zur Herstellung von organischen

For producing organic  sulfur  compounds  by conversion of
hydrocarbons or halogen  containing  hydrocarbons  with  a
halogen and  sulfur dioxide in the presence of catalysts, it  is
advantageous to use those halides as catalysts which favor the
halogenation  to carbon. The following halides can be used: the
chlorides  of  iron, copper,  nickel,  tin,  titanium,  zirconium,
bismuth, boron, antimony; phosphorus iodide; and the halogen
compounds as sulfur. Saturated  paraffins such as cetan  can be
used  for hydrocarbons,   those  obtained  at  the catalytic
hydrogenation of  the oxides of  carbon at normal or increased
pressure, those which arise at the separation of water from ox-
ygen containing products of the catalytic hydrogenation of the
oxides of carbon and hydrogenated,  or polymerized  olefins.
The temperature of the process  should not exceed 50 C.

The evolution of  neoformed buds in Nicotiana sylvestris was
studied in the inductive  photoperiod, under conditions most
favorable for the initiation of floral buds of Nicotiana tabacum
'Wisconsin 38'. Grown in vitro in a nutritive Knop composi-
tion containing agar and glucose and illuminated  from  9 to 16
hours per day, plant fragments were analyzed at regular inter-
vals using standard histological techniques. Fragments taken
from  the plants  formed buds from the resulting callus. The
morphological appearance of the buds was independent of glu-
cose concentration in the growth medium, length  of lighting
periods, and  place of sampling in inflorescence. Eight plates
show  views  of sectioned specimens. Although formed  in eu-
period in composition rich in sugar, the buds  were vegetative
and comparable to those formed in dysperiod in a composition
poor in sugar. Observations indicated that glucose  does not
cause  flowering in vitro  but  favors  it when induced. The
evolution of neoformed buds is similar to the growth of apical
meristems of entire plants until the reproductive phase, when
the meristem stops functioning and becomes parenchymatous,
and leaves yellow and wither.

A ceratodon purpureue protonema grown in  darkness  in  a
composition containing glucose and 8-azaguanine (0.000032M.)
in vitro loses  some  of its power of  branching,  while its
lengthwise growth remains unchanged. Guanine added to the
inhibiting  composition  in  a  concentration of  0.0000066M.
restores  normal  branching. Since this  phenomenon  is  not
found in the presence of 5-FUDR, the 8-azaguinine appears to
be an inhibitor of the synthesis of RNA. The 8-azaguinine has
the same effect on  the  oblique  mitosis of  the  ceratodon
protonema as on the biodimensional growth of the prothallus
fem. This favors the hypothesis of an  analogy between the
two phenomena.

Solid  particles   in a  fluidized bed receive an  electrostatic
charge as a result of friction with other particles and the walls
of the  bed. Both electric and hydrodynamic processes  are in-
volved in charging the particles, and many factors, such as the
dielectric constant of the fluidized mass, have pronounced ef-
fects on the results. The  polarity  of the  charged species in
mono-and multi- dielectric  systems and  the characteristics of
deposits of these species were studied. Moisture-free air was
used to fluidize  dried particles in a bed fitted with D. C. elec-
trodes. The  charge on the  fluidized particles was  determined
by observing the polarity of the electrode on which  the parti-
cles collected (e.g. positive particles are attracted to  the nega-
tive electrode).  During the  fluidization  of  one-component
systems, both positively and negatively charged particles were
found.  In two-component systems, the species with the higher
dielectric constant was generally positively charged. This is in
agreement with Koehn's Law. Sand, a constituent of all three-
component systems examined,  was always negatively charged,
the other two holding a positive charge. On rod-shaped elec-
trodes, particles  would form a cluster at the lower, free end of
the rod when the electrode was grounded to the metallic bed-
supporting  screen. When  the electrode was insulated, two
clusters were formed. One, the component usually attracted to
that electrode, formed a  band part way up the shaft. The other
component formed the usual cluster on the end of the rod.
Materials tested include KNO3, SiO3,  NaCl, Mg  CO3, Ca
CO3, BaSO4, Pb(NO3)2, and coal.

Manganese  in drinking water, it origin, the problems it causes,
and its removal are discussed. Though manganese represents
only 0.1% of the earth's crust, standing water (but not running
water) has a tendency to concentrate it; concentrations in ex-
cess of 20 ppm  have been  obtained in some reservoirs. While
manganese  is essential  to plants,  it can do expensive damage
in  paper  mills, wood pulping,  and the manufacture of rayon
and plastics. In the  home, it can leave bard-to-remove stains
on laundry and reduce or stop the flow of water by precipitat-
ing on  the walls  of  pipes.  The  development  of removal
techniques is traced  through the years and several of the more
successful  techniques  that have  evolved are  presented.
General categories of techniques discussed are mechanical, ion
exchange, chemical, and catalytic, with combinations thereof
representing the most common applications.

Proceeding  from  a one-dimensional kinetic  model of  an
isothermal  gas-liquid phase, counterflow  reactor, the  mass
balances  of the reaction components for the gas phase and the
liquid phase,  as well as continuity equations of both phases
and the reaction space, are formulated.  In addition, impulse
balances  of both phases and the reaction  space are derived.
The impulse-balance equation for reactor space and the con-
tinuity equations for gas and liquid phases are used to obtain
differential  equations for static pressure in a cross section of
the reactor  and the relative volume share of the gas phase. By
deriving impulse-balances to the gravitational and compression
force, the equations for the static pressure are simplified to an
inhomogeneous, linear  differential equation  of the first order.
By integration,  static pressure as depending on the lenght of
the reactor can be obtained. Moreover, the differential equa-
tions can be  transformed  into equations for determining the
mean relative volume shares of the gas and the fluid phases in
any given segment of the reactor. The relations set up for gas-
liquid phase reactors can be modified, in the case  of constant
volume shares by introducing the  mass density and the relative
volume share of the mixture  of  liquid and solid to apply to
gas-liquid phase reactors  with  a  suspended  solid content.

                        A device to automatically water plants in pot-type containers
                        is described. Previous methods provided water on the basis of
                        weight, but they are not practical for widespread experimental
                        stations at external locations. The  method described involves
                        the use  of ceramic cylinders to be  used as  suction fixtures
                        operating in  a negative  pressure  metering device. Pressure
                        develops because of evaporation  between the soil and the
                        cylinder. At  a proper  hydrostatic connection between the
                        supply container  and the ceramic cylinder, water replenish-
                        ment is automatic. Water has been supplied for as long as 14
                        trouble-free days by this method. (Author abstract modified)

                        Experiments are reported on the decompositions of hydrogen
                        sulfite with ultraviolet radiation, to investigate photochemical
                        methods of aerosol formation. Such methods  have the ad-
                        vantage of permitting a constant reaction and nucleus forma-
                        tion in the entire reaction vessel, and sensitive control of the
                        reaction through radiation dosage. The diluted  and purified gas
                        is passed into a ring-shaped radiation  pipe. After radiation, the
                        reaction mixture  is thinned and transferred  into an aerosol
                        centrifuge for measuring the size distribution of the aerosol.
                        This  distribution  depends upon the duration of radiation and
                        the concentration of the gas.  Magnification  of the  product
                        from duration time and concentration results in a  shift of the
                        distribution function toward larger particles. A changing, inter-
                        mittent  radiation of  the  reaction   mixture  results  in  a
                        monodispersed size distribution.

The chemical mechanism of inhibition of the ferment enolase
by fluoride was investigated. Fluoride inhibition of three com-
pounds was being determined: fluoride, magnesium salt, and
phosphate. When the magnesium concentration was constant
and the fluoride and phosphate varied, the equation phosphate
times fluoride times remainder of  effect/inhibition of effect
equal constant was found.  When the phosphate concentration
was constant and the fluoride and magnesium salt varied, the
equation magnesium salt times fluoride times remainder of ef-
fect/inhibition of effect equal  constant was found. Since it  is
difficult to determine such a  small phosphate concentration,
the equation was not tested for large fluoride concentrations.
However,  both equations were  tested  and found to be valid
for fluoride concentrations of 1/20,000 to 1/100.  It was con-
cluded that the effective compound for fluoride inhibition is a
complex magnesium-fluoro-phosphate.  This  compound  com-
bines  in  proportion  to  its concentration  with the  ferment
protein in  a dissociating manner. The specific reversible inhibi-
tion is believed to be based on the  displacement of the effec-
tive magnesium salt from the protein by the complex.

An analog computer program  was developed to determine
first-order reaction kinetics involved in the isotherm pyrolysis
of coal. The calculated constants of reaction  speed can be as-
signed to  reaction  phases  independent of the degree of car-
bonization. Activation energies  of  48-66 kcal/mol and thrust
factors of 10 to the  13th power  to  10  to the  17th  power
reciprocal  min  were   determined  for  methane,  propane,
ethylene, and carbon monoxide generated by the  pyrolysis of
bituminous coal. For ethane,  these  values lie between 50-90
kcal/mol and 10 to  the  14th  power to 10 to the 25th power
reciprocal min. In a second analog computer program, kinetic
reaction data  obtained  in the  first program  were  used  to
establish degasing curves to be expected for  a given speed of
heating up under nonisothermal conditions.  (Author introduc-

The dew points of flue gases  with small sulfuric acid concen-
trations are determined  with  the aid of thermodynamic rela-
tionships.  The theoretical values obtained are compared with
previous measured results. The dew point characteristics of a
mixture of H2SO4 and water  vapor at  lowest partial pressure
ratios are  discussed. The presence of other gases in a flue gas
will have no effect on dewing  as long as they do not react with
H2SO4. The dew point characteristics given  are valid only in
those conditions were equilibrium conditions are reached. How
this agrees with reality is a question of condensation kinetics.
The dew point problem in the cylinders of internal combustion
engines has become more critical due  to  changes in fuel
characteristics  and a demand for higher  longevity of the en-
gines. Rapidly  changing thermodynamic parameters within the
cylinder make the problem more complex.

Formation of  methane,  ethane  and hydrogen were  observed
volumetrically  and by means of gas  chromatography during
isothermal pyrolyses of bituminuous coal, vitrinite and exinite
in a vacuum between 400 and 500 C.  The constants of speed
of reaction, activation energies  (40 to 65 kcal/mol) and pertur-
bation  factors of the individual reaction stages were calculated
from the values measured according to the method of the least
square deviations. The gas formation curves which were mea-
sured non-isothermally were  analyzed with the kinetic values
found.  A comparison with kinetic data found by various ex-
perimental methods showed essentially good agreement. While
the formation curves for the total amount of gas,  methane and
hydrogen were quite similar  to  each other, the curve for the
formation of ethane deviated noticeably. Values  for methane
and hydrogen which are approximately equal indicate that the
formation of these gases takes place according  .to  the same
reaction mechanism, but the  mechanism for ethane formation
is yet to be investigated. The appendix describes  the fitting of
a curve on data  points by linear or non-linear regression and
iterative calculation by the method of steepest descent.

A spectrographic analysis of the luminescence observed during

about 400 C in a special furnace, a strong luminescence is in-
duced. The emission spectrum is in the visible and ultraviolet
regions,  which coincides with  known ozone data.  Measure-
ments of an ozonized mixture of oxygen and nitrogen are also
studied. The mechanism of the  observed luminescence is ex-
plained, and the concepts of processes occurring during ozone
formation in glow discharge are verified.  The nature of ozone
luminescence is independent of the substances which are ox-
idized.  Special spectrographic techniques and  equipment are
developed for the purposes of this investigation.

Chemisorption as  the  initial step in the activation  of  gas
molecule on solid interaction surfaces is the first step in the
catalytic  process. The  strength of the bonding between the
substratemolecule and the surface in chemisorption determines
whether a catalytic process or binding between the substrate
and  solid body  results.  I  oxidation  reactions,  it has been
known since 1955 that optimal binding strength of the  oxygen
in oxides is the  criteria for good catalytic activity. This op-
timum for the binding conditions of oxygen can be more close-
ly characterized through conductivity measurements. Measure-
ments are made for a series of reactions involving catalysts of
alkali earth chromates.  The  results  of  the  experiments are
discussed in terms of activation energy, kinetics, and reaction

When nitrogen oxides were brought into contact with  tributyl
phosphate and Di-2-ethylhexylphosphoric acid in the presence

A method of obtaining sulfur and  iron by the desulfurization
reaction of pyrolotite FeS was studied. The sulfur was  esti-
mated by the iodine method and iron by the standard potassi-
um permanganate method.  The sample consisted of 83.2%
                         FeS. An electric furnace was used to heat a quartz reaction
                         tube to a preassigned temperature and air was exhausted from
                         the  system by nitrogen.  The sample was broken into small
                         pieces and inserted in the quartz reaction  tube. The nitrogen
                         was  switched to sulfur dioxide at a constant speed.  After a
                         given amount of reaction time the SO2 is again switched to
                         nitrogen, the temperature of the electric furnace was lowered,
                         the  sample removed, and the reaction rate was calculated by
                         estimating  the leftover sulfur. Equations are given for the cal-
                         culation of the thermodynamic analysis of the reaction. To
                         find the best conditions for the reaction, a constant-size sam-
                         ple, 0.5 g,  was used and  the reaction time set for 1 hour. By
                         changing the temperature and the flow velocity of SO2,  the
                         reaction time could be studied. When a temperature higher
                         than 900 C is used with the appropriate flow velocity of SO2
                         (40-60 cc) the reaction takes place almost perfectly in 90 to 120
                         minutes.

                         Research  being conducted on the chemistry of pollen was
                         reviewed.  The principal results obtained from  the pine tree
                         pollen which causes  sarcoidosis were reported.  Various sam-
                         ples  of pollen, collected by bees, such as mixed pollen, apple
                         pollen,  and rockrose pollen were examined. The substances at-
                         tractive to the bees as well as substances that can be obtained
                         in the pure state  were identified. The substance 24-methylene-
                         cholesterol was isolated from  two pure pollens and one mixed
                         pollen.  It was previously shown that insects cannot synthesize
                         sterols.  Hence,  the  24-methylene-cholesterol  isolated from
                         bees could come either from  the food or a transformation of a
                         phytosterol. Having isolated 24-methylene-cholesterol in a con-
                         siderable  quantity from  different pollens shows  the purely
                         food origin of this sterol.

                         hydrogen sulfide under ultraviolet radiation into hydrogen and
                         sulfur. The production involved passing a mixture of H2S and
                         nitrogen through a microsorban filter to an illumination pipe
                         where the  gas mixture was exposed to the unfiltered light of a
                         200 mercury steam lamp located in the center of the pipe. The

reaction mixture was then thinned with filtered nitrogen and
conducted to an aerosol centrifuge with which the power dis-
tribution of the  aerosol was measured.  Particle size  distribu-
tion was found to be influenced by the H2S concentration and
length of stay of the gas mixture in the illumination pipe and
even more  so by intermittent illumination of the reaction mix-
ture. The latter produced monodisperse aerosols with a narrow
size distribution as the result of homogeneous condensation.

Finely distributed admixtures to  a flow  of gas, which bounce
against, glide along, or are torn away from  the delimitation of
a flow, are electrically charged. Besides  the static electric pro-
perties of the two bodies  in contact, the contents of dust of
the gas principally determine the intensity of the charge of all
particles. The influence of the size of grain  on the electric
capacity of dust is examined, and results are obtained from an
electrostatic measurement of  the dust  contents. Exhaustive
measurements were taken on various types of dust; results ob-
tained from quick ash are  used as a sample for the method of
calculation   and  the  accuracy   of  the measurement.  The
chargeability of  single particles, boundary charge and particle
number of  a dust cloud, and measurement of charging are ex-
amined.  Variations  of the  granulation unquestionably  in-
fluenced the total charge. As  long as they  stayed within the
customary  practical  limits, the indications  of the measuring
device  also  remained  within   the  permissible  limits  of
tolerances for measuring dust.

The  kinetics  of the reaction between sulfur  dioxide and
hydrogen sulfide within the range 250-350 C, occurring in the
contact apparatus of sulfuric acid plants  and the  effect of
reaction vessel surface and type  of wall surface on the reac-
tion  rate were studied. The  reaction proceeds exclusively on
the walls of the reaction vessel.  Within  the pressure and tem-
perature range studied, the reaction rate in a glass  vessel is
directly proportional to the sum of the partial pressures of an
equivalent mixture of the reagent gases. The ratio of the quan-
tities of H2S and SO2, reacted in a unit of time and was equal
to the ratio of the surfaces of the vessels  in vessels  of  dif-
ferent dimensions. The reaction was sensitive to the state of
the reaction vessel surface and the reaction rate  varied widely
in response to changes in the state of the surface. The cover-
ing of the surface of the glass reaction vessel with metal films
of iron, copper, and aluminum and the exposure of films of
these materials to  H2S and SO2 mixtures, showed that in all
cases the reaction is retarded by comparison with glass sur-
faces.  However, with a film containing aluminum, the reaction
proceeds more rapidly than with all the other films and  ap-
proximates the rate on a pure glass surface.

A flow method was used to determine the coagulation constant

radius of 100  A (Knudsen aerosol number approximately  2).
The average value of the constant was 13.4-10 to the minus

with the Fuks equation for the coagulation constant in the in-
termediate range. The role of molecular forces in coagulation
of dioctyl  sebacate aerosol with an average particle radius of

The fractionation of oxygen isotopes in the dissociation of  sul-
fur dioxide by electron impact was studied with a mass spec-
trometer modified for precision isotope analysis. An isotope
separation factor of 1.046  was calculated from the ratios of
ionic current with M/e equal to 48, 50, 64, and 66 for SO2 with
natural isotope content SO2 enriched with 02(18). The experi-
mental separation value was in satisfactory  agreement with
theoretical separation factors calculated by the Franck-Condon
and Bigeleisen methods. The separation data imply that,  on
dissociation of SO2 by electron impact, the S-O  bonds are not
distorted in the resulting transition complex. This is consistent
with the hypothesis that the energy of the bombarding electron
is not distributed among all the bonds and leads  solely to  the
dissociation of an individual bond.

This information  on inhaled noxious  pollutants, which  is
presented  in brief semi-outline form, deals with: chronic and
acute effects, influence of dusts on the lungs, influence of
non-carcinogenic pollutants, influence of bacteria and viruses,
and principal areas of concern in research. Pollutants must be
considered both for their independent effect  and for that
which is conditioned by the state of health of the person such
as that of persons with cardiovascular impairment or chronic
bronchitis. Reactions from  a number of pollutants,  including
ozone, nitrous vapors, and carbon monoxide, are of great con-
cern. Research  studies are being pursued with synthetic at-
mospheres in relation to synergistic actions; with studies of
the atmosphere  in certain areas of Paris  during a normal
period and during a period of smog; with lexicological studies
of certain chemical agents, particularly sulfur dioxide, carbon
monoxide, and  various  fluorine  compounds, with a view of
fixing their limits of tolerance; with the carcinogenic potential
of chemical agents as pollutants; and with consideration of the

THE PROBLEMS OF BASIC URBAN AIR POLLUTION.  H
problems  dell'inquinamento  di  fondo  urbano  dell'aria  at-
mosferica. Fumi Polveri (Milan) 6, (6) 177-8, June 1966.
Basic urban air  pollution refers to the discharge into the air of
exhaust gases from motor vehicles and from heating  units,
which  are prevalently  inefficient.  Both  sources discharge
respirable dusts and gases, the latter including some aliphatic
and aromatic hydrocarbons which have proven carcinogenic in
experimental  animals. The  problem  arising  from  the  in-
complete  combustion of motor fuels  is aggravated by the
presence, in Italian cities, of narrow streets and relatively high
buildings which  become repositories of emitted fumes and dust
from slow-moving vehicles. As much as 12 to 13% CO may be
present in gasoline-driven motor car exhaust. While gross mea-
surement of pollutants present in the urban  air is of high in-
dicative value,  public health  aspects of the  problem demand
that  granulometric studies of the dust particles also be con-
ducted, since size is a  factor in  respirability.  In  addition,
photochemical  studies involving the interaction between the
pollutants in the  air and the sun's rays  indicate that solar
radiation transforms the originally present contaminants into
biologically more receptive compounds, quite  different from
their precursors. Thus  peroxacetylnitrate(PAN)  is produced
from NOx, and  the new substance is a powerful irritant of the
mucus  membranes.  The dramatic  episodes of mass  illness
resulting from smog in various  places in recent  years were
caused  by the  phenomenon  of thermal  inversion  which
prevented the dispersion of the irritants present in the air.

Manganese cyclopentadienyltricarbonyl (MTC) is toxigenic in
small concentrations  and  has pronounced cumulative proper-
ties. A single exposure to MCT vapors in 0.1  mg/1 concentra-
tions in  the air is dangerous for life. In concentrations  of 0.01
mg/1 in the air this  substance  may  cause serious and lethal
poisoning in cases of multiple exposures. Concentrations at a
level of 0.001  mg/1 produce  functional  shifts in the nervous
system  and initial morphological lesions in the respiratory
tract. The new antidetonator is endowed with a weak irrigating
effect at rhe site of contact; when dissolved in oil and benzene
it  does  not penetrate the skin. The  solvent tetrahydrofuran,
which is used in the  production of  MCT in tetrahydrofuran
penetrates intact skin and  causes intoxication.

Opinions are  divergent concerning the effect of long-term in-
halation of low concentrations of gases and aerosols which can
cause pulmonary edema. This paper investigates the time rela-
tionships in the  formation  of increased  tolerance to  such
gases, its duration,  the  influence of time  and concentration,
and the pathological-anatomical reaction of lung tissue to the
preliminary treatment. After the protective mechanism was
proved to be independent of the chemical structure of the irri-
tant, NO2 was  chosed as representative of the gases causing
pulmonary edema. Most of the laboratory  animals used  were
inbred mice of  the CFW and  NMRI families (Zentral-institut
fur Versuchstierzucht, Hannover), which  were brought into
the test weighing 18-22 gin. Increased  tolerance to high con-
centrations of NO2 was obtained by exposing the specimens to
40 ppm NO2 for one 6-hr period. The protection reaction first
appears within 24 hr.  Maximum protection occurs in 2-5 days
and is largely gone after 10 days. Repeated preliminary expo-
sure with the same concentrations at 4-day intervals does not
increase the amount or duration of protection.

To be injurious to men, suspended particles in the atmosphere
must  be inhaled  and deposited  in  the lungs.  Only particles
smaller than 5 microns and especially  smaller than 1 micron
can penetrate into deep sections of the  lungs. Other important
factors are the  type  and dissolvability  of the dust as well as
the volume and frequency of respiration. To determine the
deposition of dust in lungs, it is necessary to determine the
difference between  the dust content of inhaled and  exhaled
air. A test conducted to determine the effect of gases found in
large cities on the amount of dust deposited in lungs utilized a
mixture of 2 types  of soot with  air which was sprayed and
measured with  a special apparatus. Spectrophotometric and
quantitative methods were used  to determine the amount  of
dust deposited in the  lungs of test persons who respired at a
rate of 1% breaths per minute,  temperature  of 23 dog. C, and a
humidity of about 68%. Typical gases mixed with the test
suspension in the dust chamber were SO2 and CO2 or NO2 in
concentrations which correspond to the MAK values. An in-
crease in dust deposition in  the lungs was observed only when
nitrogen  gases  were  inhaled  simultaneously.  Further  tests
showed that the elimination of deposited dust from the lungs is
hindered by SO2 and SO3.

The cellular  activity is  followed by  the  phagocytic  and
metabolic activity. The cytotoxic effect of influenza virus on
the macrophages was followed by the  oxygen  consumption
and carbon dioxide evolved. With carbon dust there was no
change in cell vitality or metabolic activity. With  silica dust
there was a  cytotoxic  effect,  but  with  the  addition  of
polyvinylpyridine-N-oxide there was a  protective action  and
the microcinematographic pictures were normal.

OZONE.  Text in Japanese. Kuki Seijo (Clean Air-J. Japan Air

The methods  of production, toxic nature, and methods of de-
tection of ozone are described. The Denshi Ozonizer No. 1  is
illustrated in whkh oxygen or air is passed between the dielec-
tric plates and a silent discharge by high voltage a.c. produces
ozone. The ozone concentration varies according to humidity
and temperature of  the air,  low temperature and humidity
being favorable for effective utilization of the ozone. Part of
the toxic  character of ozone  comes  from  the  presence of
nitrogen oxide as an impurity. The maximum allowable con-
centration of each in its pure state is 20 ppm but when mixed,
1 ppm is the maximum. Uses of ozone for air cleaning, oxida-
tion of  organic  compounds,  sterilization,  water  cleaning,
deodorization, etc. are covered. Ozone detection methods are
divided into  chemical  and  physical  methods. The  physical
method is more convenient and fast.  Usually  the  odor of
ozone permits its detection  before much harm to the human
body can occur.

vomiting,  lack of coordination of movements, amnesia, and
headache. In the same table in parallel columns are listed the
symptoms of exposure to vanadium, sulfur dioxide, and oxides
of nitrogen. Based on an examination of the soot involved it
was  concluded that  the vanadium was  not involved in the
symptoms of the chimney  sweeps and that the sulfur content
of the  fuel was an important factor. It is recommended that
fuels low in sulfur be used, that the optimum combustion con-
ditions be maintained by keeping the temperature of the flame
down by a high excess of outside air. Electrostatic precipita-
tors  can cut the emission of SO3 by 50%. The  injection of

Lung tissue has been examined from victims of fatal  accidents
in Osaka, Japan to determine the location, amount, and chemi-
cal composition of black-dust deposits  due to air pollution.
The nature of pulmonary lesions was also studied. Information
is given on the preparation of the specimens for microscopic
and chemical analysis. Tabulated data give comparative infor-
mation on (1) the amount of black dust deposits in people over
the age of 40, (2) the relationship between  connective tissue
development and the amount of  black dust deposits, (3) the
number of dust foci over 1 mm in size and the occurrence of
bullous emphysema, (4) the weight of dust and  the percentage
of silica in the lungs  of persons 46, 58, and  63  years old, and
(5) the  weight of the various chemical  elements in persons
over 58 yr. Large deposits of black  dust were  frequently ob-
served in  persons over 60. Perivascular  proliferation of con-
nective  tissue increased  with  an  increase  of   black  dust
deposits. In macro-specimens, nodular foci per unit area in-
creased with increasing age. This  suggests that intrapulmonary
black dust depsotion due  to air pollution increases  with age.
Further studies are recommended.

THE  USEFULNESS  OF THE METHOD OF SINE  WAVE
OSCILLATING  PRESSURE   FOR   MEASURING   TOTAL
RESPIRATORY FLOW RESISTANCE IN HUMAN SUBJECTS
AND  GUINEA PIGS.  Text  in  Japanese. Japan.  J.  Hyg.
(Tokyo), 21(6):424 436, Feb. 1967. 18 refs.
The  validity and  applicability of  a  sine  wave oscillation
method for measuring total respiratory flow resistance in man
and guinea pigs were investigated. Diagrams giving exact mea-
surements of the body plethysmographs  and the pressure im-
posing  device used  in  the experiments are   provided. The
frequency of the sine wave oscillation with which the activity
of the chest-lung system becomes  zero, was found to be 7 ap-
proximately 9 c.p.s. in both man and guinea pig. Over 12 c.p.s.
the impedance of the system showed a steep rise. By analyz-
ing the flow and its imposed pressure curves, it was found that
the total respiratory flow resistance showed continuous change
according to the different stages of the flow curve. By the use
of an  artificial mouthpiece resistor having three  kinds of
known resistance  in  man, the frequencies 7 approximately 9
c.p.s. also showed  the most pertinent reproducibility, and the
impendence was overestimated by frequencies below or above
this range. When this technique was applied to  the short term
                        inhalation study of low concentration of SO2 (1.5-2.0 ppm) in
                        man, it revealed rapid  response and individual difference of
                        the sensitivity of the total respiratory flow resistance after a
                        few seconds of the exposure. In long term exposure of guinea
                        pigs to 0.1 ppm of toluene diisocyanate vapor without any sur-
                        gical treatment, the animals showed a  repeated  day to day
                        response with different individual sensitivity, and when sodi-
                        um chloride aerosols were added the response of the total
                        respiratory flow resistance was affected in a meaningful pat-
                        tern.  The results, which are illustrated in graphs and tables,

                        Plasma spray coating  of  metals is accompanied by  health
                        hazards,  such  as  high-frequency   noise,  the  presence of

                        air and ultraviolet radiation. The aerodynamic noise levels may
                        attain 128-130 db. A special polyclinical and physiological ex-
                        amination of workers showed disturbed vascular  tone with a
                        tendency towards hypotension, slowed-down pulse and abnor-
                        mal cardiac rhythm,  as  well as an increased threshold of audi-
                        tory sensitivity by the end  of the work day. Workers with a
                        service record of 2-5  years exhibited impaired hearing with
                        distorted perception  of high-pitched  tones.  Recommendations
                        are  made for  reducing  the health hazards of operators.

The various toxic components in automobile exhaust gases are
reviewed.  To determine the  amount of carbon monoxide in-
haled by  the population,  the carbon monoxide  hemoglobin
content  of 331  policemen and 597 automobile drivers  was
determined during  a test  for alcohol.  The nonsmoking po-
licemen  did not exceed the 5% limit, but 25% of smoking po-
licemen  and 40% of the drivers did. The amount of lead in the
street, in windowsill dust,  and in the street air was well as in
the blood  of office workers,  metal work- ers and garage wor-
kers  was determined in Zurich between 1948-1963. While the
amount of lead in the dust  of the street, air, and win- dow sills
increased significantly by 1955, the amount found in the blood
increased only slightly. Soot is considered deleterious as a car-
rier of other water soluble  toxic substances into the lungs. The
hygienic limit of 0.5 cc./cu  m for oxides of nitrogen is only sel-
dom   exceeded. Sulfur  dioxide  emissions   are  negligible.
Hydrocarbons and  polycyclic hydrocarbon  emissions  from
motor vehicles  contribute  only a few percent to  the rise in
lung  cancer. The paraffin and olefin hydrocarbons are nontox-
ic  to humans,  animals and  plants,  while  ethylene is  highly
toxic to plants. While in Europe oxidants do  not contribute
significantly to  air pollution, compounds  such as  ozone and
peroxyacylnitrite contribute to air pollution in  tropic and sub-
tropic climates with a high  concentration of motor vehicle traf-
fic, particularly under adverse meteorological conditions. The
psychological problems caused by air pollution are discussed
and  it is concluded that the  psychological effects cannot be
dismissed  lightly.

Workers in various professions exposed to lead vapors or dust
in concentrations exceeding  0.01 mg/cubic meter were ex-
amined and working capability was evaluated  on the basis of
clinical  symptoms and general condition.  In earlier stages of
poisoning, temporary transfer to working places without expo-
sure  to lead is recommended.  Where the symptoms do not dis-
appear, then permanent retirement must be recommended. The
average  exposure time before retirenent due to chronic poison-
ing was  11.6  years for men and  12 years for  women. Retire-
ment of women is less frequent than for men, which is at-
tributed  to the less hazardous  conditions for women.

RELATIONSHIP BETWEEN LEAD LEVEL IN BLOOD  AND

Lead levels are tabulated for 789 urine and  blood samples ob-
tained from persons in 16 countries and major cities who had
not been occupationally or otherwise exposed to lead.  Lead
levels in blood  and urine  ranged  from 7-26microgram% in
blood and 22-46 microgram/1 in urine. Analysis of the data
showed that the lead concentration in the blood is directly pro-
portional to that  in urine. An in- crease in the blood level of 1
microgram % is accompanied by an increase in the  urine level
of 1.4 microgram/1. A plot of lead concentration in the blood
vs.  that in the urine gives a straight line which intersects the
urine concentration ordinate at a value of about  12 micro-
gram/1. Since this is impossible it appears that the  correlation
line must be curved in the lower concentra- tion range. The
proportionality between the lead concentration in the urine and
in the blood is considered as indirect evidence that lead at nor-
mal blood levels  is excreted by glomerular filtra- tion only.

to establish a relationship between the death rate and the high
dust  concentrations hi the  air  (2.4-5.0 mg./m.3).  While the
death rate increased by 29% over the period  3-17  December
1962, the  absence  of regular  concentration  measurements
made any correlation imposs- ble.

EFFECT OF AIR POLLUTION IN  THE GOP (UPPER SBLE-

Air pollution in Poland causes economic losses estimated at 8
million zloty annually and, in addition, it exerts a noxious in-
fluence on human health. This condition is  acute in Katowice
province, where  23 percent of the  Polish labor force is em-
ployed on 3 percent of the land, and particularly affects the
GOP, an area of 2,000 sq. km with 2,800 people per sq. km.
Some 733 school children from the area of Chorzow, in the
center of the GOP, were studied over a 7-year period (1959-
1966). The  most common respiratory illness was rhinitis (31
percent of Group A, from  Corzow Stary,  and 26  percent in
Group B, from Katowice-Ochojec). Tonsillitis was reported in
9.2  percent of Group A and 19 percent in Group B, and  aller-
gic  rhinitis in 58 percent  and 8 percent respectively.  It is
evident that air pollution has an effect on the incidence of or-
dinary and allergic rhinitis. The inverse relationship of tonsil-

litis to air pollution leads to the supposition that some frac-
tions in the polluting emissions may stimulate the lymphatic
system. The highest pollution was reported from the area of a
nitrogen plant,  with  an  average dust fall of 602.28 g/ sq ml
month  and  a daily  average  of SO2 concentration of 2.24
mg/100 sq cm PbO2. Chemical analysis of the dust revealed 74
percent inorganic, 25 percent  organic and 0.5  percent tarry
substances. Data  from low pollution points in  the Katowice-
Ochojec suburban area showed an average dust fall of 23.03
g/sq m/month and a  daily average  SO2 concentration of 0.91
mg/100 sq cm PbO2.

THE INFLUENCE OF  AIR POLLUTION IN  YOKKAICHI
CITY  OF THE VENTILATORY FUNCTION  OF SCHOOL
CHILDREN.   Text  in  Japanese.  Nippon  Shonika Gakukai

41 refs.
Ventilation function  studies with school children  were con-
ducted over a 15-month  period in order  to investigate the ef-
fect of air pollution due to petroleum  industry installations
built since 1955 in Yokkaichi, Japan. Wright peak flow  meter
measurements for children aged 6-12, and Vitalor MMF (peak
flow rate) measurements for children aged  10-12, were carried
out, using about 1,080 children  from a polluted area and about
290 from  a non-polluted area.  In  addition,  FRC,  FVC,
FEV0.5, and FEB1.0 were investigated.  Chronic reduction of
ventilation  function is noticed in  school  children aged 6-12
from the polluted area. The difference between polluted area
residents decreases with age. This is especially noticeable for
girls. Disturbance of ventilation function generally appears as
obstructive  difficulties   rather  than restrictive  difficulties
because of  the apparent reduction in  FRC,  MMF50-75%,
FEV1.0 and FEV0.5, and also  a slight reduction in FVC. The
differences  between polluted  and  non-polluted  areas were
found to be more noticeable in winter than in summer. Ven-
tilatory disturbances  in polluted area school children may be
enhanced by low rainfalls, dry air, and low  temperatures in the
winter. Judging  from  the wide range of scatter in the reduction
of ventilatory function,  individual  changes attributable  to air
pollution appear to vary considerably. Inhalation of soot or
SO2 stimulates tracheal mucus, causing non -infectious inflam-
mation. Then viral or bacterial  infection leads to spreading in-
flammation (asthmatic patients  tend to suffer from this,  in ad-
dition to the allergic inflammation). The patient will tend to
have swollen  tracheal mucus, chronic  edema or  bronchial
spasms. A long-range follow-up study  of these children  is
recommended  to  cover  the period from  childhood through
adolescence to adulthood, in order to determine the extent to
which air pollution influences ventilatory  capacity.

Little is known about the effect of  transitory CO poisoning of
an expectant mother on  the development of the unborn child.
A few  reported German  and Polish cases are discussed where
expectant mothers suffered CO poisoning with periods of un-
                         consciousness ranging from 30 min. to 5 hr. In the Polish case,
                         the mother was poisoned in the seventh month of pregnancy.
                         While the mothers did not  show any  neurological symptoms
                         after regaining consciousness,  the carbon monoxide in each
                         case  exerted a damaging and lasting effect upon  the fetus or
                         neonate. Fetal effects included brain damage,  retardation, idio-
                         cy,  and  severe  and  vast  necrosis in the  central nervous
                         system,  leading to death within a few hours or days. The
                         severity  of the damage appears to be related to the month of
                         pregnancy, with the fetus being particularly vulnerable shortly
                         before parturition. It is not resolved whether carbon monoxide
                         acts directly through the circulatory system on the fetal ner-
                         vous system or  whether the  mother's  oxygen deficiency
                         brought about by carbon monoxide poisoning causes seconda-
                         ry damages to the fetal brain. A Caesarean delivery should be
                         effected in order to permit the child to exhale CO through the
                         lungs.

                         Six groups of albino rats were  exposed to ore dust containing
                         69.5% Si02, 14.7% Z1203. 5.46% iron oxides, etc. The groups
                         were exposed to different concentrations, ranging from  50 to
                         500 mg./cu m, and for different periods of time. The product
                         of  exposure time  and concentration  was the same for all
                         groups  so that groups exposed at a high concentration were
                         exposed for a shorter time  and conversely. Determination of
                         pulmonary collagen lipids, and dust contents as well as micro-
                         scopic examination, showed that 6-12 months after the inhala-
                         tions the histochemical changes were similar in all groups. In
                         particular, the group exposed to a lower concentration  for a
                         longer  period of  time exhibited more  pronounced  pneu-
                         moconiotic symptoms.  The group exposed to higher concentra-

                         pneumoconiotic symptoms. The group  exposed to higher con-

                         changes in the upper respiratory tract.

LARGE LYMPHOCYTES IN  THE BLOOD  OF  PATIENTS
WITH CHRONIC LEAD POISONING.  ((Sui grand! linfociti

High percentages (19-59%) of large lymphocytes were found in
the peripheral blood of 20 patients with saturnism employed in
the manufacturing of storage batteries. These cells, stained by
the method of Unna-Pappenheim, showed intense cytoplasmic
basophilia. In the peripheral  blood of 20 subjects not exposed
to lead, the  percentage of large lymphocytes was within nor-

bibliographic data on the significance of the large lymphocytes
and of changes of Coombs'  test  in saturnism. The usefulness
of the determination of large lymphocytes in saturnism is
emphasized.

AN UP-TO-DATE REVIEW OF THE EFFECTS OF AIR POL-
LUTION ON THE POPULATION.  ((Uber die Auswirkung der
Luftverunreinigung auf die Bevolkerung   Eine neure  Uber-
sicht-)) Text in  German. Z. Ges.  Hyg., 14(6):410-413, June,
1968. 24 refs.
The  effects  of the increasing incidence of air pollution on
human health are discussed. Distinction is made among the im-
mediate (24-48  hr.), delayed (weeks to months), and chronic
effects (years)  of exposure  to air  pollution. Four  areas con-
sidered  are: non-specific respiratory  diseases; experimental
and epidemiological studies on chronic effects of air pollution;
studies on premorbid conditions  resulting  from air pollution;
and incidence of lung cancer. Air pollution is viewed as one of
many etiological factors influencing incidence  of colds, in-
fluenza  and other respiratory conditions,  but  it  may be  a
precipitating factor in the development of  chronic  conditions.
Statistical  correlations  between  air  pollution  (oxides  of
nitrogen, sulfur, and silicon) and urban incidence  of chronic
bronchitis,  keratoconjunctivitis,  atonia  and penumonia have
been reported. Rheumatic heart disease seems more related to
socioeconomic factors than to air pollution. Urban children ex-
posed to air pollution show microcytic anemia and  retardation
of bone development. Correlation between urban air pollution
and lung cancer has been noted. A decrease in lung cancer
mortality was  reported among British  immigrants to  USA,
Australia or  South Africa even though their cigarette consump-
tion remained the same or increased.

A FOLLOW UP STUDY  OF  THE DAILY INCIDENCE  OF
RESPIRATORY SYMPTOMS  AMONG  A  GROUP HAVING
CHRONIC BRONCHITIS IN CONNECTION WITH AIR POL-
LUTION OF TOKYO-YOKOHAMA AREA.  Text in English.
Asian Med. J., 11(9):1-12, Sept. 1968. 12 refs.
Sixty-three persons (21-55 yrs.) with symptoms of sneezing,
running nose,  coughing, phlegm, throat irritation,  headache
and fever, and diagnosed to have chronic bronchitis as a result
of examination, spirometry and  questioning,  were selected
from 1000 male workers  in a casting company in  the Tokyo-
Yokohama  area (a highly polluted, industrial area). The  pa-
tients were observed from August 1963 through July 1964, dur-
ing which time their symptoms were correlated with dust fall,
sulfation rate,  daily  visability, wind speed, suspended parti-
cles, and sulfur dioxide. The significant  positive relationships
found between sneezing and dust fall during the whole obser-
vation period, between sneezing and sulfur dioxide and phlegm
and  sulfur dioxide  during the first 8 months,  and between
phlegm and suspended particulates suggest that patients with
chronic  bronchitis are sensitive to irritants  in the air. It ap-
pears from  the negative relationship between  headache and
mean velocity that an environmental factor might be involved.

Meteoropathology is examined in an attempt to gain insight
into  human pre-sensing of weather changes,  even inside of
buildings. Atmospheric pressure, environmental elements, and
fluctuations and  their  attenuation inside  of  buildings  are
treated in theoretical detail. Special attention is given to fluc-
tuation of ozone concentration inside of structures. The com-
plicating effect  of time lag between inside and outside  condi-
tions is stressed.

Brain acid phosphatase was studied in four rabbits acutely or
subacutely intoxicated with tetraethyl lead. The acutely intox-
icated rabbits received  the toxic  substance intravenously in
gum arabic emulsion in  doses of 60 or 90 mg Pbt/kg of body
weight. The subacutely  intoxicated rabbits received  10 or 50
Pbt/kg of body weight in 95% alcohol subcutaneously on 10
successive days. No significant change in the distribution of
the enzyme in  the various  areas of the encephalon was ob-
served between control  animals and rabbits acutely and  sub-
acutely treated. Tetraethyl lead was found in the brain tissue
of all animals: 4.26 mg in animals treated with 60 mg/kg; 43.57
mg in animals treated with 90 mg/kg; and 0.43 and 0.15 mg in
animals treated with 10  and 50 mg/kg. The  findings  are con-
sidered significant, since many drugs  exert an effect on brain
phosphatase activity.

In the fall of 1965,  three groups of Slovak children were ex-
amined for the  effects of environmental conditions  on body
height, structure,  and hemoglobin  levels. The first group had
spent the summer in a recreational area; the second lived in an
area  highly polluted  by arsenic emissions from a. power plant;
and the third group lived in a less polluted area and had spent
the summer at scout camps. Measurements in the spring of the

year had indicated the maximum mean height of children from
the unpolluted area agreed with the overall Slovak average.
Though lower growth levels for the children from the polluted
area were not statistically significant, no child in the second
group was classified as very tall. Marked differences  were
established in  hemoglobin values  and warning differences in
red blood cell  values. In the fall, there was substantially nar-
rower scatter of the relative heights of children who  had spent
the summer in the scout camps  and recreational  area. Ex-
tremes of body structure within each group had disappeared
and differences in hemoglobin levels were less marked, in-
dicating the leveling effect of proper diets  and purer air. The
children from the polluted area continued to exhibit not only
decreased hemoglobin values but decreased  red blood cell
counts.

SYNTHETIC  ALCOHOL PLANT  AND  THEIR EFFECT ON
MORBIDITY,  SANITARY AND LIVING  CONDITIONS OF
THE POPULATION. Gigiena i Sanit., no.  9:3-7, 1961. 5 refs.
Translated from Russian. 7p.
Investigations were undertaken to  determine the extent of the
area affected by the discharges from a synthetic alcohol plant
and the effect of these discharges on the  morbidity rate and
sanitary and living conditions of the population. The area was
found to be polluted by hydrocarbons, hydrogen sulfide, and
sulfuric gas in  a  radius  up to  3 km  and by unsaturated
hydrocarbons up to 500 meters. In a survey of the local popu-
lation,  many  complaints  were  associated with the wastes
emitted by the plant (headaches,  dizziness, loss of appetite,
etc.). The complaints were most numerous close to  the plant.
During  a  three-year period,  the incidence  of respiratory dis-
eases in children in the plant area  exceeded the morbidity rate
of children in a control area. It is concluded that children's in-
stitutions and residential settlements should be located at least
3 km from the plant. (Author conclusions modified)

Excessive air pollution by arsenic  was observed in the area of
a thermal power plant. The hair of ten-year old boys living in
the vicinity of the plant  was tested for arsenic content in a
study of the feasibility of using  arsenic hair determinations as
indicators of nonprofessional exposure. As normal  values of
arsenic  content in children's hair  were not available, the ob-
tained values  were compared with  the  values  of  a control
group of ten-year old boys from a village where arsenic levels
fell within a normal  range. In  both areas, a comparatively
broad scatter span of arsenic values was observed.  However,
the average value for the boys from the polluted zone was 3
1/2 times  higher than that for the boys from the unpolluted
area. The increased content of arsenic in hair is attributed to
increased amounts of arsenic in vegetables and fruit  as a result
of soil contamination and to direct hair contamination by flue
dust.

                        A survey on respiratory diseases (asthma, bronchitis, common
                        cold, cough) was conducted in Kashima, a rural area in Japan.
                        A revised questionnaire of the British Medical Research Coun-
                        cil was used for the survey which was conducted along with
                        simple pulmonary ventilatory function tests on 678 randomly
                        selected  adults of both sexes 40 to 65 years of age. The at-
                        mospheric sulfur dioxide concentration, the aerosol concentra-
                        tion, wind direction, and wind velocity  were simultaneously
                        measured. The SO2 concentration was below 0.01 ppm, the
                        weight density of the  suspended particulates ranged from 500
                        micrograms/cu  m  (maximum)   to   13  micrograms/cu  m
                        (minimum); the  average was 90   micrograms/cu  m.  The
                        response  rate  to  the  interview survey was high: 91.6% for
                        males; 95.5% for females; and 93.8% for the total. Prevalences
                        of respiratory symptoms were  computed for each question;
                        relationships to sex, age, and the amount  of  smoking were
                        determined. The survey results were also compared to those
                        obtained in England, the U. S., and Canada. The prevalences
                        in males were higher than in females; those of older persons
                        were higher than  of  younger ones; and those of smokers,
                        higher than those of nonsmokers.  International comparison
                        revealed that the prevalences in the  Kashima area  were con-
                        siderably lower than those in the agricultural areas of England,
                        the U. S., and Canada. The pulmonary function tests revealed
                        a slightly higher forced expiratory volume than that of mail-
                        truck drivers in London.

                        Between  1961  and 1962 and 1963  and 1964,  the dust fall and
                        the atmospheric sulfur dioxide concentrations were measured
                        at 13 stations in the Yokkaichi  area.  The dust fall was deter-
                        mined by means of sedimentation; the SO2 concentration, by
                        the PbO2 method.  Equivalence lines were  drawn  each year
                        from the annual averages.  The monthly National Health In-
                        surance records were  used  to study the effect of these pollu-
                        tants on humans of all age groups. Calculation of the correla-
                        tion coefficients revealed a  definite correlation between such
                        diseases  as bronchitis, eye diseases, and laryngopharyngitis in
                        the infant age group  as well as bronchial asthma in the age
                        group above 50. The correlation was particularly high between
                        laryngopharyngitis among infants from  age 0-4 as  well as
                        bronchial asthma among adults  or more than 50 yearn of age.
                        The diseases were  correlated with SO2  rather than with the
                        dust fall. Bronchial asthma  increased from the middle of 1961
                        to the present in the polluted area, which coincides with an in-
                        crease of the SO2 concentration; no such pronounced increase
                        was observed in the non-polluted area.

Various studies were undertaken to determine the transient ef-
fect of industrial dust on lung function. In one test, healthy
male subjects averaging 25 years of age were exposed for six
hours in a working area of a steel and iron foundry  to 18 ppm
carbon monoxide and 0.08  ppm  sulfur  dioxide. No worker
demonstrated the onset of any acute  loss of respiratory func-
tion. Only one difference was noted in MTV values as  deter-
mined by the Fowler Test before the start and after the end of
the working day. The difference was not statistically signifi-
cant. Tests were also conducted with  workers exposed to 0.24
ppm in the foundry pit. No detectable changes were recorded
with respect to  vital capacity, maximum expiration value, and
respiratory minute  volume.  However,  respiration rate  in-
creased by 11.9% and depth of respiration declined by 9%,
suggesting that dust potentiates  SO2 action.  The  effects  of
chronic exposure to dust in a study concerned with measure-
ment of pulmonary function in a group of older persons need
to be taken into account. Subjective reactions  to SO2 concen-
trations less than 1 ppm were noted  in older emphysema pa-
tients when the  weather  was foggy and  small amounts  of
hydrogen sulf ide were present in the atmosphere.

Osseous  age  is  defined as  the period  in human  life during
which bones  increase in size and become mature.  A total of
2424 x-ray pictures of the left wrist  and  hand of Czech chil-
dren, ages 6-16, were evaluated by the method of Greulich and
Pyle. Whereas the growth of girls was comparable to those of
American girls, there was a delay of  about one year in Czech
boys during early school years. A  definite relationship was
demonstrated between level of growth and osseous age. Chil-
dren living in polluted areas experienced  a retarded osseous
maturation as compared with those living in clean-air areas. A
new method was developed for evaluating osseous age,  which
was used to compile statistics.

Twenty-one air pollution studies are summarized. Of the  21, 18
concern the effects of pollutants on human health, and in par-
ticular, their relationship to respiratory diseases and respirato-
ry functions; the remaining studies deal with economic losses
caused by pollution, corrosion of metals,  and  the adsorptive
capacity of indoor surfaces  for gaseous  substances. Subjects
covered include a method for estimating  the  absorptivity  of
the airway mucuous membrane for gaseous sulfur dioxide and
nitrogen dioxide; in the incidence of chronic bronchitis in pol-
luted and unpolluted areas; effects of  pollution on the pharynx
and larynx of school children; effects of automotive exhausts
on human health; the deposition of granular and gaseous sub-
stances in the respiratory tract; the effect of NO2 on pulmona-
ry CO diffusing capacity and airway resistance; effects of O3
on pulmonary volume; effects of NO2 on ventilatory functions
in  healthy  individuals;  the   relationship between  chronic
respiratory diseases and air pollution;  effects  of SO2 on air-
way sensitization; an epidemiological investigation of a pollu-
tion episode involving a sulfuric acid plant; and the effect of
control measures on mortality figures for heart and respiratory

Dust hi the lungs of ten diseased persons from non-industrial
areas and IS persons from industrial areas were analyzed. In
six cases dusts found in the lymph nodes were also available.
None of the persons had  died of any  lung disease or of any
disease  due to dust inhalation. All dusts were  separated from
the lungs  and lymph nodes by  the formamide method. Diame-
ters of  the dust particles  were determined with electron and
light  microscopes.  The frequency  maxima  of the  particle
diameters, as well as the  medians of  the  particle  size plots,
were found  to  lie  below  1  micron.  An   approximately
logarithmic normal  distribution was found. The dust  particle
size spectra of three samples (lung dust from industrial areas,
lung dust from residential areas, and lymph node dust from in-
dustrial areas) differed little from each other and agreed with
the corresponding spectrum of  airborne dust in large industrial
cities. Electron microscopy further showed that only fine dust
particles accumulate in the lungs; large particles either do not
penetrate into the interstitial tissue, or if they do, they are
eliminated again. Direct particle  size  analysis showed  that
quartz particles of more than 3.5 microns predominated.

The distribution of carbon monoxide is discussed, particularly
that arising from automobile exhaust gases, and an empirical
formula is given for calculating the carbon monoxide  content
at any height, given a background concentration, the  number
of vehicles per hour, and  a constant which in turn is a func-
tion of  the width of the road  and the height of the exhaust.
The hemoglobin-CO reaction in the blood is reviewed, and stu-
dies made on police officers hi Paris are cited  in which levels
of blood carbon  monoxide were determined. In non-smokers,
there was a  definite  rise hi concentration. Levels fixed in
California for carbon monoxide hi ambient air are cited as 30
ppm for 8 hours or 120 ppm for 1 hour for serious  exposure;
exposure of 240 ppm for 1 hour can cause acute illness, since
10% of the hemoglobin is bound  as carboxyhemoglobin. Ef-
fects of carbon monoxide hi man other than combination with
hemoglobin are cited, i.e., effects on the blood-forming ap-
paratus, circulatory system, and the eye. Other pollutants aris-

ing from automobile exhaust  are mentioned, including lead,
oxides of nitrogen, compounds produced by photochemical
reactions with ozone, and aldehydes. In conclusion, the many
differences in allowable levels of carbon monoxide in Russia
and western countries are pointed out, and the differences in
carbon monoxide ingestion between smokers and non-smokers.
A common sense approach to  setting standards for air quality
is advocated.

Tetrodotoxin at a dose level of 0.00001 g/ml, decreased the ac-
tion potential in isolated embryonic rat hearts at 13, 16, and 21
days post-coitus, presumably by specifically inhibiting  sodium
flow. Manganese,  in doses of 4 mM/L, shortened the  plateau
of the action potential, its  effect being more noticeable at 13
days than at 16  or 21 days. Tetraethylammonium chknide, 20
mM/L also inhibited the action potential; in this case the age
of the embryos made no difference.

Six healthy adults aged 20  to 36 were experimentally exposed
to SO2  gas, and five healthy  adults aged 18 to 37 were ex-
posed to  N02  gas.  Pulmonary flow  resistance, pulmonary
compliance, FRC,  and respiratory  rate were  measured. Con-
centrations of SO2 during the  experiment were 36 to 40 ppm;
those  of NO2 were 6 to  17 ppm. Experimental exposure to
these   two  gases  and   similar analyses  were  made  in
anesthetized dogs and guinea pigs. Flow resistances of the
lungs  and thorax  because  of  bronchoconstriction were com-
monly increased by both SO2  and NO2 in three experiments.
                        The following response to these gases, however, differed. In-
                        crease of pulmonary flow resistance to SO2 was inhibited by
                        the subcutaneous administration of 0.7 rng of atropine sulfate,
                        but no inhibition by atropine was observed with NO2. Respira-
                        tory rate was increased by NO2 and decreased by SO2 in an
                        experiment with guinea  pigs.  Variation  in  pulmonary com-
                        pliance was more marked with NO2 than with SO2. The SO2
                        was  found to stimulate  mainly the  upper  respiratory tract
                        (nose, throat, and upper  trachea) because it is water-soluble
                        and because more than 95% of it is absorbed within the upper
                        respiratory tract. The NO2 was found to stimulate mainly the
                        peripheral portion  of  the lung  because it does not dissolve
                        easily in water and thus is easily brought to the peripheral por-
                        tion  of the respiratory tracts. Nitrogen dioxide was found to
                        have  an oxidizing  action  and to damage the pulmonary mu-
                        cosae more markedly than the reductive action of SO2.

                        A survey was conducted  of  the absentee rate at six primary
                        schools (three in  polluted areas and three in  non-polluted
                        areas) from Sept.  1966 to  March 1967. Both percentage of ab-
                        sentee days and number of children absent were higher at the
                        control schools, but the rate of  respiratory tract disease among
                        absentee children  was higher at the schools  in polluted areas.
                        From April 1967 to March 1968, both percentages of absentee
                        days and uumber of children absent were higher at the schools
                        in polluted areas. The  polluted area schools Sad & higher level
                        (1.19%) than the control schools (0.52%) of the children suffer-
                        ing from asthma. Furthermore, average frequency of absence
                        per child was higher  at the  former (3.13 times)  than at the
                        latter (1.54' times). On close  medical examination of children
                        with suspected asthma, the percentage of children diagnosed
                        as having bronchial asthma was 0.65% for control schools and
                        1.21% for the others.  Furthermore, 50-80%  of  the suspected
                        cases of asthma determined by questionnaires can be diag-
                        nosed clinically as asthma.

                        To study the effect of exposure to nitrogen dioxide gas on
                        lungs and trachea, mice four weeks of  age  were placed in  a
                        exposure chamber and continuously exposed  for 30 days to 0.7
                        to 0.8 ppm concentrations of  nitrogen dioxide gas, supplied by
                        heating liquid NO2. Air  for dilution was passed through  a
                        dehumidifier, filter, and activated carbon. Air velocity in the
                        chamber was 5 cm/sec, temperature 24 to 26 deg, relative hu-
                        midity 40 to 70%,  and *he light transmission rate of dust was
                        less  than 1%. The mice were given ample food and water. A
                        control group of mice was raised under similar conditions but
                        in the absence of NO2. No statistically significant difference
                        in growth rate was observed between groups. On the 15th day
                        of exposure  to the  gas, accelerated  secretion of mucus,

degeneration, and desquamation were observed at the mucus
epithelium  of the trachea.  Lung  congestion  and  increased
secretion of mucus in bronchial tubes was also noted. By the
30th day, advanced negative and degeneration of the mucus
epithelium was evident in both lungs and trachea. The results
show that catarrhal changes  in lung and trachea occur follow-
ing exposure to less than  1% (sic; 1 ppm/) NO2 gas.

ETIOLOGICAL CONSIDERATIONS  WITH   RESPECT TO
CHRONIC BRONCHITIS IN JAPAN. (Honpo ni okem mansei
kikanshien  no byoin-teki kosatsu). Text in Japanese. Nippon
Rinsho (Japan Clin.), 25(9):2054-2063, Sept. 1967. 34 refs.
The  etiological influence of air pollution on the incidence of
chronic bronchitis is  discussed.  Six areas in Osaka  and its
vicinity were classified into  three severely, one moderately,
and  two mildly polluted  areas. Concentrations of SO2,  NO2,
and  ozone  and amount  of  settling dust were measured. In-
cidence of chronic bronchitis in the severly polluted  areas was
higher (twice as great in males  and three times as great  in
females) than that in the mildly  polluted areas. Males were
more frequently and severly involved than females. Smoking
and  SO2 concentration were the most important causes of this
disease in any  district, and  the correlation between the con-
centration of SO2 and occurrence of chronic bronchitis was
demonstrated mathematically. In younger age  groups, certain
constitutional factors influence the occurrence of the disease,
while in older age groups, environmental factors are more in-
fluential. It was difficult to determine the minimal predisposing
conditions  necessary  to provoke  chronic bronchitis,  since
there were so many variations in  physical conditions among
the subjects.

ON THE EFFECTS OF AIR POLLUTION ON THE  POPULA-
TION. A NEW REVIEW.  (Ueber die Auswirkung  der  Luft-
verunreinigung auf die Bevoelkerung. Eine neuere Uebersicht).
Text in German. Z. Ges. Hyg.  (Berlin),  14(6):410-413, June
1968. 24 refs.
A review of the known effects  of air pollution  on human
health is presented. In polluted areas, the mortality  rate from
diseases of  the respiratory tract is nine times higher  than  in
rural areas.  A linear relationship was found to exist between
the  smoke  content of the  atmosphere and  diseases of the
respiratory  tract and the circulatory system. The disease rate
of female employees of radio stations in five  U. S. cities also
showed a relationship between diseases of the respiratory tract
and  air pollution. A connection between the physical condition
of school children and the content of free silicon dioxide in at-
mospheric dust was found in the USSR. Japanese studies also
confirm an increased occurrence of diseases of the respiratory
tract and the eyes in polluted areas. In an industrial area with
heavy smoke and dust pollution but low SO2 pollution, Czech
scientists found lower  hemoglobin concentrations  but con-
siderably higher alkaline phosphatase concentrations and  a
high incidence of rickets in children. In a heavily SO2-polluted
area of northern  Bohemia,  children had considerably higher
numbers of erythrocytes but less hemocrit. According to  other
Czech studies, the bone development  of children living in
heavily polluted areas was retarded.

AIR POLLUTION AND PUBLIC HEALTH IN ROTTERDAM.
RESULTS OF AN INVESTIGATION  ON THE ACUTE EF-

An investigation was made of  possible direct effects of three
air pollution peaks on human health  in Rotterdam. For this
purpose, daily mortality and morbidity data were collected for
December 1952,  January and February 1959, March 1961, and
December  1962. High air pollution  concentrations  compared
with average winter levels existed on January 29, 1959, March
8, 1962. Results  show small increases in general mortality and
hospital admissions of persons over 50 years of age for car-
diovascular and  respiratory diseases each time. The increases
in mortality were greatest among persons over 60 years of age
and in the diagnostic groups of tumors and cardiovascular dis-
eases. For 1962,  a more detailed search was made for data that
might support the assumption of a casual  relationship with air
pollution. It was found that a  control population, exposed to
the same weather but less air  pollution, showed a  much less
marked  effect on  mortality and sick leave absenteeism. In
1952, Rotterdam was covered by dense fog from December 5-
9. Though London  experienced a severe effect that time, there
was no  clear effect in Rotterdam. No air pollution measure-
ments were made  in 1952, but it is common  knowledge that
the emission of pollutants, especially of SO2, was much lower
10 years ago. The findings seem to indicate that Rotterdam has
reached a level of industrialization and urbanization at which
air pollution effects on human health begin to manifest them-
selves during abnormal weather once  or more  every 3 years.

This paper reviews what is known about lead metabolism, and
discusses   biochemical   toxicology,  the  biosynthesis  of
porphyrins,  iron metabolism,  the effect  of lead on mature
erythrocytes, and other metabolic disturbances. The complexi-
ty of lead metabolism precludes any diagnostic value of iso-
lated lead level determinations  in blood or urine. To demon-
strate the state of impregnation of the organism with this tox-
in, the test of provoked urinary lead excretion  should be per-
formed in the chronic stage. Furthermore, a battery of assays
including the levels of delta-ALA, PEG,  CP  and free PP in
erythrocytes   are   required   to  reveal   the  biochemical
disturbances at  the target level where individual  variations
may play a role.

Four groups of five rats each were subjected to a diet of bread
and milk for 6 months. The rats in the first group were fed 50
rag/kg sodium fluoride per day; the second group, 2 mg sodi-
um iodide per animal; the third group, fluoride and iodide at
the same time; and the fourth group received neither of these
substances. The  growth of rats receiving fluorine was better
than that of the  control group for 3 months, then slackened,
and on the sixth month was less. The hair was less silky and
blood marks appeared at the nostrils and on the vagina. The
rats that were iodized  and fluoridized had the same symptoms,
but more accentuated. Iodide given alone favored growth. The
teeth  of fluoridized rats had uniform whiteness  and  marked
elongation of superior incisors. The enamel presented undu-
lated prisms and numerous Retzius brown streaks; superficial
pigmentation  was completely lacking.  In the group receiving
fluoride and iodide, the alterations were less marked; the teeth
were more compact. Bones and organs were also studied, but
noted modifications were not substantial.

The enzyme activity of fish egg adenosine triphosphatase (AT-
Pase) and the relationship of the ATPase  to  the Ca(2+) ion
was  studied. An EDTA concentration of  0.005 and higher
completely removes ATPase activity of extracts from  infertile
sturgeon eggs.  The  effect of  Mg(2+),  Mn(2+),  Ca(2+),
Ba(2+), and Sr(2+) was  studied in  the presence of 0.001 M
EDTA.  All the cations demonstrated  an activating effect. In
protein fractions obtained by the precipitation of  extracts and
homogenates with  (NH4)2SO4 and  subsequent dialysis, AT-
Pase activity was found only in the presence of bivalent ca-
tions. The  cations, from greatest to  least, according to the
degree  of  activating  effects, were  arranged in  the  order
Mn(2+), Mg(2+), Ca(2+); Sr(2+), and Ba(2+) were inactive.
In spite of the presence of a quite active S'-nucleotidase in the
protein precipitates, ATPase activity  could be singled out by
carrying experiments at acid pH values. In the pH zone equal
to 5.5 S'-nucleotidase was inactive. Subcellular fractions of 450
g, 20,000  g, and a supernatant were  isolated by differential
centrifugation  in sucrose. Addition of bivalent cations caused
the activation of ATPase; Mg(2+) ions activated more  strongly
than Ca(2+) ions. Data indicated that  the presence  of Ca(2+)
ions which are required for fertilization cannot be related to
their activating effect on ATPase, since neither  Mn(2+) nor
Mg (2+) can replace Ca(2+) in the process of fertilization. It
was established that pyrophosphatase  of sturgeon eggs is ac-
tivated, by Mg(2+) but not Mn(2+). Thus, it was assumed that
orthophosphate is split off from ATP by the action of ATPase
and not pyrophosphate. The slight splitting of phosphate from
ADP, established  earlier,  demonstrated that  the ATPase of
sturgeon eggs  splits from  ATP  only one terminal phosphate.

SYMPOSIUM  ON  ASTHMA. EFFECT OF AIR POLLUTION
UPON BRONCHIAL  ASTHMA.   (Shinpojyumu—Zensoku).
Text  in  Japanese. Nippon Naika  Gakkai Zasshi  (Tokyo),
58(12):1287-1292, Dec. 10, 1969. 23 refs.
Presumable causes of asthmatic attacks are allergy response,
disease  of the trachea, and a  combination of  physical and
                         mental factors. In actual fact, these factors are not insepara-
                         ble: each  contributes  to  the resistance against  inhaled an-
                         tibodies and each is highly sensitive to chemical mediators iso-
                         lated from cells under the influence of antibpdvcompounds.
                         For this reasons, bronchial asthma is characterizSTby a con"
                         stitutional  predisposition to allergy  response, i.e., an inclina-
                         tion to produce a resistance 'factor' against an antibody. The
                         present study  centers on  the relationship  between the re-
                         sistance factor and the sensitivity to chemical mediators and
                         air pollution. Asthmatic attacks were found to be closely re-
                         lated to weather conditions: more were observed on rainy days
                         and during unseasonable weather than  on fine days. The risk
                         of attacks increased when the temperature declined 3 C below
                         that of the previous day. Another finding was that SO2 inhala-
                         tion increased stimulation through the vagii. Asthmatic patients
                         were more sensitive to SO2 inhalation than healthy persons. In
                         some patients, bronchoconstriction was eased by  atropine in-
                         jections. Today chronic bronchitis is generally used as a deter-
                         minant index  to the effect of air pollution  on asthmatic pa-
                         tients: air  pollution  is  considered to influence  asthma with
                         respect to an infection factor. It is not definitely known, how-
                         ever, whether air pollution results in bronchial asthma.

                         The correlation between respiratory and cardiovascular dis-
                         eases and  atmospheric conditions (temperature and humidity)
                         and smoking  was investigated by examining the death rate
                         (1962-1964) from  the  diseases  in  longtime residents  of
                         Kawasaki city, 60 years and older. The  collection ratio  of the
                         data was 74%. The mortality figures for persons who had lived
                         in polluted areas of  the city  longer than five years  were 345
                         males (81.59%) and 281 females (77.55%); the figures for re-
                         sidents of  the nonpolluted  area were 210 males (70.48%) and
                         208 females (68.15%). The  death rate  was high in winter and
                         increased even more  in summer when SO2 concentrations
                         were highest (in 1963, the maximum SO2 concentration in the
                         industrial district between July and September was  6.405 mg
                         SO2/day/100 sq cm PbO2). In the polluted area, there was an
                         increase in deaths from  cardiovascular diseases, expecially
                         vascular damage to the central nervous system, and pulmonary
                         tuberculosis. Deaths  attributed  to  respiratory diseases  had
                         decreased. In the nonpolluted area, there was an increase in
                         deaths from neoplasm in  the respiratory organs and  from
                         bronchial asthma. Among smokers the incidence of death from
                         neoplasm in the respiratory organs, arteriosclerotic heart dis-
                         ease, and bronchial asthma was highest in the polluted areas.
                         The deaths are correlated  with high humidity, low tempera-

Studies of  the  influence  of sodium bicarbonate  and the
bivalent metal ions Mg(2+), Mn(2+), and Zn(2+)  substances
favorable  to CO2 fixation processes in animal tissue, on the
intensity of the renewal of proteins, glycogen, and lipids of the
liver and  muscles of rabbits are reported. Male  rabbits were
fed a diet of sodium bicarbonate and sulfuric acid salts of the
indicated  metals for ten days. The diet caused no noticeable
changes in the interrelation of dry substance, lipids, glycogen,
and proteins in the liver and muscle tissues. Among changes in
the intensity of metabolic processes in  substances was the
considerable removal  of  carbohydrates in liver and muscles;
this was manifested by the rapid inclusion of acetate-2-C 14 in
glycogen and its exclusion. There was a considerable activa-
tion of the inclusion of radioactive carbon the tissue proteins,
especially in muscle protein. It is concluded that the stimula-
tion of carboxylation processes visibly activates the renovation
of carbohydrates and  the intensity  of the  incorporation  of
radioactivity of protein. Lipid metabolism is influenced to a
lesser degree.

Among the methods of nitrogen-dioxide removal, washing by
water or alkaline solutions are only 50% effective.  The author
investigated  a  method based on ammonia gas. For the sake of
comparison, an experiment using water alone was conducted.
Nitrogen dioxide concentration was about 200 to  300 ppm; gas
velocity, 0.6 1/min; and water volume,  20 ml. Removal effi-
ciency was only 30 to 40%. Next, washing by a caustic soda
solution was examined. The caustic  soda concentration was
10% under  identical  experimental  conditions.  The  rate  of
removal was 40 to 50%. The rate of nitrogen dioxide removal
by ammonia was 85 to 95%. The drawback of  this method,
however,  is that it generates white smoke of  ammonium nitrite
or nitrate. In the experiments conducted at a plant site, wash-
ing by water removed only  12 to 55% nitrogen dioxide while
ammonia removed 70 to 93%. Hydrofluoric acid  is harmful to
silkworms. Mulberry leaves containing 1  mg of fluorine per
100 g  of  leaves completely killed silkworms. Elimination  of
hydrofluoric acid was comparatively  easy. Satisfactory results
were achieved by  alkaline washing. The  removal rate of this
method was higher than 99% and the acid concentration of tail
gas was lower than  1 ppm. The mortality rate of silkworms fed
untreated  mulberry leaves was  3.0 percent; that of controls
was 2.0.

Anesthetization with nitrous oxide  in cases of  sthenocardia
and of myocardial infarction has found a wide application  in
the practice of emergency medical treatments and in a series
of clinics. Observations  made  at the Leningrad  station of
emergency medical treatment have shown that  in  many pa-
tients suffering from sthenocardia and from  myocardial infar-
cion, after anesthetization with nitrous oxide, there appeared
on the electrocardiogram symptoms of an improvement of the
coronary blood circulation, along with the disappearance of
the pain. These observations suggest that nitrous oxide, in pos-
sessing analgesic properties,  has the ability to expand  the
spastic coronary arteries. The effect of nitrous oxide was stu-
died in a mixture with oxygen on the 'peripheral' and the 'cen-
tral' spasm of the coronary arteries. Tests were made on cats
anesthetized with urethane. Before the spasm of coronary ar-
teries induced by intravenous injection of pituitrine as  well as
during its initiation, electrocardiograms were made as a control
experiment. After 5 to 6 hours,  5 minutes after inhalation of
nitrous oxide in a mixture with oxygen, pituitrine was again in-
troduced into the same cat in the same dosage. The new elec-
trocardiogram was compared with  the  control  one. After
removal of the cerebellum, stimulations of various morphologi-
cal structures of the medulla oblongata were produced with a
unipolar electrode by square pulses lasting 5 to 10 sec with an
interval of 8 to 10 min. Electrocardiograms were made before,
during, and  after cessation  of the  stimulation.  After  ap-
pearance on the electrocardiogram of symptoms of a spasm of
coronary arteries, which served  as a control, the  experiment
was repeated  during  inhalation  of nitrous  oxide  (5 minutes
after beginning the inhalation). At the end of the experiments,
the position of the electrode was checked by means of elec-
trolytic destruction of  the region of irritation with  a  sub-
sequent histological treatment of the sample. Nitrous oxide in
mixtures with oxygen, 1:1, 1.5:1, 2:1, and 2.5:1, prevented the
origination of the central spasm  of coronary arteries, induced
by  stimulation of various morphological structures  of  the
reticular formation of the  brain. The effectiveness of  nitrous
oxide  depended  on its  concentration  in the mixture,  on  the
type of disturbance of the rhythm  of the cardiac activity, on
the concomitant coronary  deficiency, and on the morphologi-
cal structure, subjected to stimulation. Nitrous oxide did  not
prevent the origination of  the  'peripheral' spasm of coronary
arteries, induced by the introduction of piluitrine.

The effects were studied of solutions of strophanthin (0.05%),
convallatoxin (0.03%), erysimine (0.03%), periplocin (0.025%)
and cymarine (0.05%), (introduced intravenously during 4 to 6
min in doses of 0.04 ml/kg) on the oxygen intake by the tissues
and its tension in the brain and the striated muscles of dogs
with hypoxia, induced by intraperitoneal introduction of 40 to
60 mg/kg of nembutal or by intoxication  with nitrogen  oxides.
Nembutal produces a deep narcosis with severe impairment of
breathing  and cardiac  activity;  the nitrogen oxides produce
toxic emphysema. In  the tests,  the intake of oxygen  by  the
head tissues was calculated from the arterio-venous difference
of oxyhemoglobin and the volume rate of flow of the blood
stream in  the outer jugular vein. The oxyhemoglobin concen-
trations in the carotid and the outer jugular vein were recorded
by  oxyhemographs 036-M  by the method of Kisin, while the
volume rate of flow of  the blood stream in the outer  jugular
vein was recorded by the pump-flowmeter of Kisin and Tsatu-
rov. The oxygen tensions in the cortex and the subcortex of
the temporal section of the brain,  and in the muscles of the
tongue were determined polarographically using Epstein elec-
trodes. The depolarization current was recorded  by the  ox-
yhemograph. The external  breathing was recorded by a pneu-

mograph; the pressure in the carotid, by a mercury manome-
ter. Strophanthene,  convallatoxin, erysimine,  periplocin  and
cymarine introduced, in the pressure of hypoxia, increase the
oxygen absorption by the tissues of the head and the oxygen
tension in the skeletal muscles. The oxygen  tension in the
brain is increased to a lesser degree than in the muscles and
actually decreased by them. The most pronounced changes
were found to be caused by strophamthene and convallatoxin;
somewhat less obvious ones were observed by erysimine, and
quite insignificant ones, by periplocin. The effect of cymarine
was erratic.

UPTAKE OF SO2 AND NO2  BY THE ISOLATED UPPER
AIRWAYS.  Koshu  Eiseiin Kenkyu  Hokoku (Bulletin of the
Institute of Public Health),  17(4):302-306, 1968. 9 refs.
The penetration rates of sulfur dioxide and nitrogen dioxide in
the respiratory system were studied by isolating the upper air-
ways  of  two dogs  and three  rabbits anesthetized  with in-
travenous pentobarbital sodium. The airway of nose, pharynx,
larynx, and  the  uppermost trachea  were isolated  from the
remainder of the  respiratory system by fitting a glass mask to
an animal's head. The mask was connected to a glass cannula
through which the gases were  sucked in for 10-15 min.  The
rate of uptake was  found to be nearly constant during the
period of gas passing and 99.7% for 7-87 ppm SO2 and 4-41%
ppm, NO2. The differences in  the rate of uptake may partly
explain the different responses  in the ventflatory functions of
experimental animals exposed to SO2 and NO2. (Author ab-

EFFECT  OF EXPOSURE TO THE MIXTURE OF SO2  AND
NO2 ON  VENTILATORY  FUNCTIONS OF  GUINEA PIGS.
Koshu Eiseiin Kenkyu Hokoku (Bulletin of the  Institute of
Public Health), 17(4):315-321, 1968. 13 refs.
Six quinea pigs, 280 g-440  g in  body weight, were exposed to
mixtures  containing  18 ppm sulfur  dioxide-17 ppm nitrogen
dioxide and  37 ppm  SO2-32 ppm NO2 and studied for the ef-
fects of exposure on their ventilatory function (flow resistance
of the lung plus thorax, tidal volume, and respiratory rate). No
significant changes were observed in either respiratory rate or
tidal volume. In  general, the time course of respiratory  rate
and tidal volume  changes was midway between that caused by
exposure to  the individual gases, which brought about statisti-
cally significant percent changes. The results are discussed in
terms of complicated interactions between flow  resistance,
compliance,  and lung air volume. It is hypothesized that SO2
and NO2 in combination exert their action  independently at
different  lung sites, with  changes  in flow  resistance deter-
mined chiefly by the component SO2. Below a certain level, a
mixture may cause fewer overall  changes than  individual
gases. Beyond a certain level, a mixture may become lethal in
short intervals of exposure. As  a result of exposure to 50 ppm
SO2-50  ppm  NO2,  all   animals   died  from   pulmonary
hemorrhage. None had died during exposure to 50 ppm SO2 or
NO2 alone. (Author  abstract modified)

COMPARISON  OF  THE  VENTILATORY EFFECTS  ON

                        Quantitative measurements  of ventilatory function of guinea
                        pigs were made before, during, and after two-hr exposure to 6
                        to 90 ppm of sulfur dioxide and 6 to 57 ppm of nitrogen diox-
                        ide. A significant increase in the respiratory (lungs plus thorax)
                        flow resistance was caused by exposure to both gases; the rate
                        of increase was generally higher for SO2 than for NO2. How-
                        ever, the  direction of respiratory rate response was quite dif-
                        ferent at concentrations above 6 ppm; it decreased following
                        SO2 exposure and  increased following NO2  exposure. A
                        similar pattern was observed for tidal volume response. Five
                        of the  15 guinea pigs exposed to 57  ppm of NO2 died from
                        lung hemorrhage within 48 hrs after exposure. It is suggested
                        that the differences in the ventilatory effects of SO2 and NO2
                        are due to the gases reaching different areas of the lungs.
                        Within the range of concentrations studied, it appears that
                        NO2 penetrates  deep into  the lungs, causing  a decrease in
                        compliance and a  smaller increase  in flow resistance.  Sulfur
                        dioxide, being taken up by the mucosa  of the airway before
                        reaching the peripheral portion of the lungs, could cause in-
                        creased flow resistance without a significant change in com-
                        pliance. (Author abstract modified)

                        ppm concentrations of nitrogen dioxide  on the mechanics of
                        breathing was studied in eight healthy males from  18  to 37
                        years of age. The subjects  were seated in a volume-displace-
                        ment body plethysmograph and exposed to each concentration
                        for 10 min. Pulmonary flow  resistance, pulmonary compliance,
                        and functional residual capacity was measured before, during,
                        and after  each exposure period. No subject showed  a signifi-
                        cant change in flow resistance after exposure to 2.7 ppm; the
                        average increase in flow resistance  became significant only at
                        16.9 ppm. Recovery of the average flow resistance observed at
                        16.9 ppm was essentially  complete  10 min  after exposure
                        ended. Combined data on 16.9 and 12.6 ppm exposures showed
                        that the significant increase in flow  resistance occurred within
                        5 min of the onset of exposure. No subject showed  a signifi-
                        cant reduction in pulmonary compliance. Similarly, functional
                        residual capacity, respiratory rate, tidal volume, and pulse rate
                        were found to be unaffected  by all concentrations. Atropine,
                        0.7 mg in dose, administered subcutaneously prior to exposure
                        did not inhibit the increase of flow resistance. No difference
                        was found between response to NO2 alone or in combination
                        with a submicronic NaCl aerosol. (Author abstract modified)

tory enzymes  along  with a  simultaneous  change  in  the
mitochondria. It was concluded that there are disorders of the
respiratory enzyme chain ^hophorylation. The observed reduc-
tion of. activity  of the alkaline phosphatase along with an en-
zyme  diffusion  into the interior of the cytoplasm indicates
malfunctioning resorptions and degeneration processes in the
kidneys.  Chronic manganese intoxication  causes  a  general
reduction of the activity of the adenosinetriphosphatase in the
nephrons, which leads to  a back resorption of sodium  and
potassium into the kidneys. The acid phosphatase and the acid
desoxyribonuclease show a reaction increase with a simultane-
ous enlargement of the lysosomes leaving  a diffuse reaction
product. This indicated a degeneration or a higher pinocytosis
caused by the  toxic amounts of manganese. The unspecific
esterases show  a reaction increase which pointed to disorders
of the fat metabolism.  An unchanged activity of the leucine-
aminopeptidase  indicated that the albumin metabolism is little
affected  by the toxic manganese  concentrations.  Different
changes in the enxyme activity found in the individual rabbits
indicated that each animal reacts differently. (Author summary

Histochemical  studies of the properties of the leucine-amino-
peptidase in striated muscle fibers and in the liver of 7 rabbits
poisoned  with manganese  were  performed.  The rabbits
received 3.5 mg manganese per kg of body weight daily in a
1% solution as MnC12.4H20 in a 0.15 M solution of NaCI for
32 days. The solution was injected into the marginal vein of
the ear. The control group consisted of 6 rabbits. In rabbits in-
toxicated with  manganese,  an obvious increase of the leucine-
amino-peptidase activity was noted in the muscle fibers. In the
gland cells of  the liver, a  decrease in the activity of this en-
zyme was observed. In the periphery of the liver lobulae  and
in the connective tissue, the enzyme reaction was higher than
in the control animals. It was difficult to interpret the results.
The increase in the intensity of  the leucine-amino-peptidase
activity in the  muscle tissue could be due to a direct effect of
the manganese ions on this enzyme  since they are activators
of enzymes. It was hypothesized that manganese poisoning
causes the excretion of the leucine-amino-peptidase into the
plasma.

Respiratory mechanisms were studied in  eight healthy male
volunteers during and following exposure  to 36 ppm sulfur
dioxide or 15 ppm nitrogen dioxide. An esophagus balloon was
inserted through the nose of each subject who was seated in a
body plethysmograph. A Dubois pressure type plethysmograph
was employed  for SO2 exposure, and a Mead variable volume
type 71- Krogh spirometer for N02 exposure. In both cases,
the mean value of the pulmonary flow resistance increased sig-
nificantly  at the end of the exposure. No significant difference
was observed in other measures of respiratory mechanisms ex-
cept for one subject, no difference was seen between respon-
ses to SO2 and NO2. Additional groups of subjects were ex-
posed to  SO2 and  NO2 with or without  pre-treatment with
atropine sulfate. The atropine markedly inhibited the increase
in the pulmonary flow resistance during exposure to SO2, but
not during exposure to NO2. The result suggests, as regards
the cause  of airway narrowing, that reflex bronchoconstriction
plays a  role in the exposure to S02, while other mechanisms
are also involved in the case of NO2.

The pathological effects produced by 4 samples of mine dust
of mixed composition and 1  sample of crystalling quartz (the
control) were  experimentally determined.  The  dust was in-
troduced  intratracheally to 120 albino rats. The test  results
showed that the  development of silicosis depends  not only
upon the silico content, but  also on the other chemical com-
pounds which also compose the dust. A nodular form of silico-
sis,  distinguished  by  the  appearance of  typical silicotic
nodules, developed with mine dust containing 24% free SiO2
and other chemical compounds. Pneumoconiosis of the sflico-
siderosis type  developed with mine dust containing 12% free
SiO2, 17.7% Fe2O3,  and other chemical compounds. Mine
dust  comprising 1.6%  free  SiO2,  12.8%  Fe2O3, and other
chemical compounds  caused the development of diffuse pneu-
mosclerosis without typical silicotic nodules, but with the for-
mation of minute cellular-dust foci, of the siderotic type.  In
mine dust containing large amounts of tungsten trioxide, but
no free SiO2,  a weakly pronounced diffuse pneumosclerrosis
developed as  well  as  the  formation of  cellular-dust foci
without any  pronounced histiocytic reaction around them. All
of this was accompanied by a diffuse interstitial inflammatory
process  and  by  purulent  bronchitis.   (Author  summary

Services, 535p., May  20, 1969. The  services in the foreign em-
bassies in Paris,  intergovernment organizations, and  interna-
tional associations that deal with these problems. The dangers
created by pollution and 'nuisance* problems which are urban
or industrial in origin are a direct function  of the rapid  growth
of the world population, and scientific and technical progress.
On the international level  the technical and regulatory  actions
which are to be introduced in common in a number of countries
must be defined. The work  is in four chapters: (1) a contribution
to the study of pathologic  effects produced in man and in bis
foodstuffs by inhaled and  ingested  pollutants  and  by acoustic
'nuisances';  (2) international  standardization  oi analysis and
measurement methods directed to characterizing inhaled  and in-
gested polluted media and injurious acoustic media; (3) technical
prevention of pollution of inhaled and ingested mediums and of
acoustic nuisances; and (4) essential ordinances and trends as
drawn from  the laws  and  statutes of the major countries and
prospects of an intergovernmental organization of the  regula-
tions. A summary table  of the principal intergovernmental or-
gans and  international  associations that  are  concerned with
prevention of pollution and 'nuisances' is appended. It is con-
cluded that epidemological research, international standardiza-
tion, improvement of prevention techniques, and establishment
of international conventions or charters are the main directions
of the effort  which  must be followed jointly  by  the  most
                         developed countries within the framework of intergovernmental
                         organizations, with the help of specialized international associa-
                         tions. But, to be effective, the application of the recommenda-
                         tions and international standards rests with the decisions of the
                         governments which are sincerely aware of the increasing danger
                         that threatens them if appropriate measures are not taken.

                         The results of a 2-yr medical survey which was conducted  to
                         study  the  relationship between  air pollution and respiratory
                         disease in three  polluted areas of Yokkaichi City are presented
                         in the  form of tables and graphs. The data demonstrate the ef-
                         fect of  air pollution on humans, especially  with respect  to
                         respiratory diseases. The contents are divided into two catego-
                         ries: one concerned with epidemiological aspects of the Yok-
                         kaichi type of air pollution, of which the major constituent is
                         sulfur dioxide, and one concerned with clinical hematological
                         studies. Significant  findings  are  that the highest  death rate
                         from respiratory disease occurred in the most heavily polluted
                         area of Yokkaichi and that the death rate has tended to in-
                         crease  since the advent of a petrochemical plant. It is con-
                         cluded that most cases of chronic nonspecific bronchitis are
                         related to bronchus asthma, and that cases of lung emphysema
                         have developed from bronchus  asthma rather  than chronic
                         bronchitis.

                         From  the data concerning 243 miners of the Rosice-Oslavany
                         coal mines who had  various forms of  pneumoconiosis, the
                         average time  for the development of rtg-reticulation was 17.1
                         years for the mining work. The average time for the  total un-
                         derground work was 21.5 years. For  all forms  of pneu-
                         moconiosis, the average time in mining was 17.2 years, and the
                         average time  of underground exposure was 22.6 years.  After
                         5.5  years of mining, 5% of  the rtg-reticulation developed. It
                         was estimated that 34 miners were endangered yearly by pneu-
                         moconiosis. It is recommended that miners be transferred  to
                         less dusty work sites after  17  years  of mining, although it
                         would  be  more proper to transfer the miners after  only 5.5
                         years  of the mining work. This requirement would meet great
                         resistance because of the shortage of qualified miners and also
                         in view of the fact that as a result of successful measures  of
                         the dust control commission, the dust level in RUD has been
                         reduced more than  10 times since 1963. As long as  the dust
                         level in mining exceeds the permissible concentration,  how-
                         ever, it is the responsibility of all health authorities to enforce
                         a timely transfer of  miners. The period  of 5.5 years has
                         another significant  practical  importance  since it can be used
                         for factual evaluation of the dust control  measures. Several
                         secondary factors were statistically significant in the  develop-
                         ment of pneumoconiosis among young miners, including over-
                         time work, unqualified management of  the homes of young

PLEURAMESOTHELIOMA. PRELIMINARY REPORT ON
119 CASES FROM THE HAMBURG AREA. Praxis Pneumol.,

Belov and Associates, Denver,  Colorado.
The epidemiology of 119  cases of pleuramesothelioma, a rare
malignant tumor, was studied  in Hamburg with its asbestos
and wharf industry. An analysis of the case material revealed
an increased incidence of pleural mesothelioma in Bergedorf, a
district of Hamburg where an asbestos works was located. The
role of occupational, residential, and domiciliary exposure to
asbestos in the development of the tumor is discussed. The im-
portance of  obtaining detailed records is stressed,  since
asbestos exposure may occur in a great variety of occupations.
The average interval between the first exposure and develop-
ment of the tumor was 35.2 years. Exposure to asbestos was
definitely established in 17  cases and was likely 34 cases, but
in 64 cases evidence of exposure was lacking or tenuous.

The health conditions of children living near an aluminum fac-
tory were studied. The ambient pollution from fluorine emitted
by the factory was very high. High fluorine values were found
in the  agricultural products of the areas near the factory. In
the children examined,  the  absorption of fluorine by  the
digestive and  respiratory  systems was  approximately  2.15
mg/day. The children showed a marked increase in the fluorine
content in  their teeth,  hair, nails,  and urine when compared
with children living in a non-polluted area. Clinical and labora-
tory studies  revealed  a moderate decrease in hemoglobin
values and an  increase in the red blood cell count in children
exposed  to a high absorption of fluorine. When some of the
children were  transferred to a non-polluted zone, the urinary
excretion of fluorine decreased by 40% after  one month. It
may, therefore, be assumed that the  accumulation of fluorine
is reversible. (Author summary modified)

AIR POLLUTION AND BLOOD GAS. (Taiki osen to ketsueki

Chemical substances as air pollutants are carbon fly ash, sul-
fur dioxide, sulfur trioxide,  hydrogen sulfide, nitric oxide,
nitrogen  dioxide, ammonia, ozone, carbon monoxide, carbon
dioxide, hydrogen fluoride,  hydrogen chloride, aldehydes, car-
bon hydrates, tar, radioactive gases, aerosols, etc. Gas poison-
ing cases reported in Japan during a 2-year period between
1956 and 1957 were as follows: CO, 126; NO2, 45; SO2, 45;
H2S,  12; CN,  11; and CS2, 7. SO2 and CO are the most im-
portant air pollutants observed  within the exhaust gas of facto-
ries and automobiles, respectively. CO enters the human body
only  through  respiratory organs, and  SO2  through  both
respiratory and digestive organs. Discomfort occurs when the
CO concentration is 1000 to 1200 ppm (after 1 hour's inspira-
tion) or when CO toxicity ratio (ppm x hour) is more than 600.
Mortality may occur when CO concentration is 1500 to 2000
ppm (after 1 hour's inspiration) or when CO toxicity ratio is
more than  1500, or when carboxyhemoglobin concentration is
60 to 80%. CO concentration in the ambient air is not always
parallel to COHb concentration in the blood, and the latter is
influenced  by  age, sex, condition of health, smoking,  or re-
sidence. Symptoms of  CO toxicity were shown. Harmful ef-
fects of SO2 on human bodies are irritation, especially to mu-
cosal  membranes,  (eyes,  respiratory  tract,  esophagus,
stomach, etc.), and acidosis due to the  decrease of alkaline
reserve within the blood due to H2SO3,  causing disturbances
of bone  growth  in children  or  myocardial  degeneration in
adults.

Two  groups of miners from the Ostrava-Karwin bituminous
coal area  in Czechoslovakia were observed to  determine the
danger of developing pneumoconiosis. Variations in dust expo-
sure, according to different mines  and types of underground
work, were noted. To avoid this source of error in estimating
the danger from dust exposure in the two groups, a dust expo-
sure  coefficient was introduced, based on the health  condi-
tions of  each mine  and each work  area. Tuberculosis was
found in 2.7% of those  inoculated with B. Calmette-Guerin
(BCG) in  comparison with 4.6% in the non-inoculated  group.
This  confirms the fact  that BCG inoculation provides protec-
tion from  tuberculosis in bituminous coal  miners. In com-
parison with 15.5% of inoculated persons, 35.9% of non-inocu-
lated persons  developed  bituminous coal pneumoconiosis. A
similar result  was found when comparing the frequency of
pneumoconiosis in relation to the duration and degree of dust
exposure. Among coal diggers, in those inoculated with BCG,
pneumoconiosis was found in 31.3% of the cases;  among the
non-inoculated, the figure was 58.5%. When the BCG-inocu-
lated group was subdivided according to time of inoculation,
the pneumoconiosis frequency among those inoculated  during
dust exposure was 20.5%; in those inoculated before starting
underground work, the figure was 12.1%. (Author summary

and during summer vacation. Manganese in food rations  and
excreta was titrated by  the persulfate  method. The manganese

balance was found to be extremely variable, being influenced
by individual peculiarities of manganese exchange and sexual
differences. But the  main  factor  determining  manganese
balance was the type of activities pursued by the adolescents.
Under regular conditions of learning, the manganese balance
in both sexes was positive. During the period of examinations,
the level of manganese discharged from the body increased
sharply.  However,  it  remained positive  in girls  who had
received high amounts of manganese in their food ration. With
boys who had received less manganese in their food, a nega-
tive balance was observed. The period of  summer  rest was
characterized by a high level of manganese discharge and a
relatively low retention level compared to the regular learning
process. It is concluded that adolescents should receive not
less than 0.17 to 0.20 mg per day. Based on the average weight
of adolescents, the  diet of boarding schools in the Ukraine
should contain no less than 8.5 to 10.0 mg of manganese.

The effect  of manganous chloride on nitrogen metabolism in
rats weighing 200-220 grams was studied. A 10% solution  of
manganous chloride was administered endotracheally in doses
of 20 mg manganese per rat. The animals were  decapitated on
the  1st, 6th, and 30th day after poisoning.  Members of  the
control group were also killed at the same time. The tissue stu-
died was rapidly removed, frozen in liquid air, and  carefully
pulverized. The frozen pulverized tissue was suspended and
stirred in 5% trichloroacetic  acid. Proteins were separated by
centrifugation.  Intoxication,  brought  about by  single  en-
dotracheal  administration to  rats of 10% manganous chloride
solution in  doses corresponding to IS mg of manganese per rat
was accompanied by an increase in ammonia  content in  the
blood, brain, liver, and skeletal muscles on the 1st and espe-
cially on the 6th day after administration. On the 30th day, the
ammonia content in the blood was close to its content in nor-
mal  animals; in  the  brain,  liver, and skeletal  muscles, it
remained at a high  level. Together with the increase  in am-
monia  content  in tissues,  there was  an  intensification  of
processes directed toward the elimination of its toxic  action:
an increase in content of free glutamine and of protein amide
nitrogen. The most pronounced changes in ammonia metabol-
ism occurred in liver tissue and were somewhat less in brain
tissue.

THE ROLE OF MAGNESIUM IN THE BODY.  (Rola magnezu
w ustroju). Polski Tygod. Lekar. (Warsaw),  16(37):1421-1424,
1961. 31 refs. Translated from Polish. ISp.
Magnesium is one of the most important  electrolytes in  the
body, averaging in adults about 25 g (about 43 mg per kg body
weight). The tissues contain 98% of the entire amount, with
the remaining 2% in extracellular fluids. The daily Mg require-
ment of the human body is about 220 mg; a normal diet fully
covers this requirement. A  relatively low amount of the  Mg
taken in  is absorbed,  and  this  only in the small  intestine.
About  65% of the Mg in blood plasma  is totally ionized; this
portion penetrates the tissues rather easily compared with the
remaining protein-bound 35%. Urinary excretion is the major
route of Mg elimination. Mg appears to play a major role in in-
                         tracellular metabolism; the presence of Mg ions is indispensa-
                         ble for many enzymatic reactions. Some hormonal glands seem
                         to affect its metabolism,  although the mechanisms and con-
                         trolling factors are not known. It does show a high affinity for
                         accumulation in heart muscle. In  animals, injection of Mg af-
                         fects the nervous and neuro-muscular systems, resulting in
                         depression  and reduced  nervous response,  and with large
                         doses, in coma. The change of Mg level in blood serum is a
                         significant finding in certain illnesses, for example chronic al-
                         coholism,  liver  cirrhosis,  uremia,   and diabetic  acidosis.
                         Descriptions are given of  two clinical syndromes of magnesi-
                         um metabolism: hypomagnesemia and hypennagnesemia. The
                         most convincing symptom of the former is increased irritabili-
                         ty of the neuro-muscular system, manifested by tetany attacks
                         in severe cases.

                         VDI are defined as those concentrations of pollutants in layers
                         of the open air close to the ground which may be considered
                         harmless, according to current knowledge, to  man, animal, or
                         plant during exposure  of a given frequency  and duration.
                         These values are valid only within certain ranges, only when
                         the pollutant occurs by itself rather than in mixture with other
                         pollutants, and only for the open air outside of an emitting lo-
                         cation. Nitrous gases occur in nature from electric discharges
                         in the atmosphere; technologically, they are produced from
                         such principal  sources as  the manufacture and processing of
                         nitric acid and from internal combustion engines, explosives,
                         and celluloid. Nitrous  gases, which are recognizable  by their
                         brown color and characteristic odor, comprise the following
                         nitrogen oxides  and  their  compounds: nitrogen  monoxide
                         (NO); dinitrogen trioxide (N2O3); nitrogen dioxide (NO2); and
                         dinitrogen tetroxide  (N2O4). The latter two are the  primary
                         carriers  of the toxic action of nitrous gases. The  PEC half-
                         hour mean  value set for  continuous exposure to  NO2 is 0.5
                         cm3/m3. The  PEC for intermittent exposure  (permissible ex-
                         cess above the PEC for continuous exposure) is 1.0 cu cm/cu
                         m half-hour mean value,  three times daily.  In the transition
                         from normal air into an atmosphere containing NO2, the olfac-
                         tory threshold lies at 0.1 cu  cm/cu m (calculated as NO2) and
                         the odor becomes characteristic at 0.5 cu cm/cu m, although
                         within 5-6 min olfactory perception disappears even at 20  cu
                         cm/cu m. Minor symptoms of irritation such as dry and rough
                         throat may  occur under prolonged inhalation of 1-2 cu cm/cu
                         m; with  repeated exposure, these become less and finally dis-
                         appear even after inhaling 20 cu cm/cu m for 2 hrs. Toxic ef-
                         fects of  nitrous gases on man and animals have not been dif-
                         ferentiated;  in plants, it  appears that  even  sensitive  plants
                         sustain no damage from exposure to a mean concentration of 1
                         to 2 cu cm/cu m.

The concentration of pollutants in the atmosphere is generally
low (1 ppm and less). The pollutants are either solid, gaseous,
or liquid. They vary  qualitatively and quantitatively with time
and space, so that long-term measurements are required to ob-
tain an ide of the extent of pollution. Because of this variabili-
ty, it is difficult to assess the actual danger to humans. The in-
creased mortality during the  smog episode in London of 1952
became apparent only weeks after the catastrophe at a routine
evaluation.  The  normal  death rate was  exceeded  by  4000.
Study of the life-  expectancy of humans revealed that it is
sometimes 4 to 5 years les in heavily polluted industrial cen-
ters. For instance, in the  industrial center of Most (Bohemia),
the life-expectancy for  men is lower by 4 years than in other
Bohemian areas. Study of the mortality  rate showed that  a
close relationship exists  between diseases of the respiratory
tract and air pollution in general, and smoke  and sulfur dioxide
specifically.  Significant  correlations  were found  between
bronchitis and pneumonia and the concentration of smoke and
SO2. The German Democratic Republic plans  to erect a mea-
surement grid for  air  quality measurements over the  entire
Republic. In connection with  the study of the health records of
various  groups of the population, it will be feasible to  deter-
mine the correlation between air pollution  and  the health of
the population.

AIR POLLUTION AND RESPIRATORY DISEASE OF  YAK-

Ind. Med.), no. 3:69-80, June  1, 1969. 25 refs.
The  relationship between the Yokkaichi type of asthma and
Yokkaichi air pollution, of which the major  constituent is sul-
fur dioxide from petrochemical plants, are discussed, together
with characteristics  of the pollution and its effects on respira-
tory organs. It has been widely accepted that lung emphysema
develops primarily from simple chronic bronchitis. This theory
is contradicted by a Yokkaichi study which grouped patients
with respiratory disease into  those (group  A) who had the dis-
ease before the construction of the petrochemical plants and
those (group B) who did not develop it until  after the  plants
were in operation.  Group A had a higher  incidence of lung
emphysema  than  group  B,  which tended more toward non
specific bronchial asthma. The findings are accounted to the
difference in  the length of exposure to polluted environment
by sulfurous  acid gas  from  the  plants, namely, non specific
bronchial asthma in group A developed into lung emphysema
after more  than eight years  of exposure.  The fact that more
bronchial asthma was  found in  group B  underlines the high
probability of the group passing  through the same process as
group A. This type of process is construed  to be distinctively
representative  of  the effect  of Yokkaichi air pollution. It is
concluded that chronic  bronchitis is not predominantly respon-
sible for lung  emphysema where Yokkachi  type air pollution
exists.

POLLUTION OF THE  OUT- SIDE AIR WITH  SO2 IN THE
AREA  OF  RIJNMOND.   1969 (?). Translated  from Dutch.
Belov and Associates, Denver, Colo., 7p., April 15, 1970.
Recommendations are made for maximum  emission concentra-
tions (MIC  values) for  sulfur dioxide in the  area of Rijnmond
in The  Netherlands. The  proposed MIC value for a  24-hr
average is 500 micrograms/cu m; the annual average concen-
tration should be below 150 micrograms/cu m. These values
are based on epidemiological data from the international litera-
ture, and take into account acute, subacute, and chronic expo-
sure situations. The known effects of various concentrations
of SO2 on humans, animals, plants, and materials are briefly
noted; the subacute effect on humans  during 1-3 day expo-
sures consists of  exacerbation in the condition of persons al-
ready having some health  impairment. SO2 may be primarily
an  indicator pollutant, with harmful effects arising from the
presence of other substances, e.g., sulfuric acid. The proposed
MIC values will be revised as new data become available.

THE COMBINED EFFECTS OF SMALL CONCENTRATIONS
OF NITROGEN OXIDE AND SULFUR DIOXIDE  UPON AN
ORGANISM.  Gigiena i Sanit., vol. 27:3-8, Oct. 1962. Trans-
lated  from Russian by Irene B. Sharenbroch, California  State
Dept. of Public Health, Berkeley, Air and Industrial Hygiene
Lab., 10p., Feb. 11, 1963.
A study of  the combined effect of small concentrations of
nitrogen dioxide and sulfur dioxide on  an organism, and the
character of their combined action  at these concentrations, is
discussed. The combined effects of NO2 and S02 were stu-
died by the  chronic exposure of rabbits. Also, the effects of
the isolated  actions of these gases at the same concentrations
were  studied. During the exposure and recovery period, the
changes in the blood periphery and the state of phagocytic ac-
tivity were studied, and deformations of the proteinatious frac-
tions  of  blood serum were determined. At the completion of
an  experiment,  pathomorphological  examinations  of  the
respiratory organs were made. A mixture of NO2 and SO2 did
not cause any weight reduction. Each  isolated gas caused a
decrease in the hemoglobin content at the end of chronic ex-
posure, but  this effect was not observed with exposure to a
mixture of the two. The action of NO2 lead to a decrease in
the number of erythrocytes, while a mixture of the gases and
the action of SO2 alone did not. The combined action of the
gases caused some decrease in the phagocytic activity of the
blood; the isolated action  of NO2  and  S02 produced a con-
siderable reduction of it. Modifications of the protein fractions
of blood were not observed upon inhalation of an NO2-SO2
mixture.  A mixture of NO2 and SO2 at the Maximum Allowa-
ble Concentration levels for industrial installations adversely
affected the  animal.

Chronic influences of air pollution  on people were studied in
the Tokyo metropolitan area from 1966 to 1968, mainly in Oc-
tober. Examinees totaled 6718 and included 5096  males and
1628  females. Little difference  was  shown  between  then-
places of birth, living and employment The survey comprised
an interview using question-and-answer cards, pulmonary ven-
tilation tests,  and a sputum  examination. The  metropolitan
area was divided into 3 areas  according to the severity of air
pollution due to sulfur dioxide: the severely polluted area had
a 0.05 ppm SO2 concentration; moderately polluted area had a

SO2 concentration of 0.03 to 0.04 ppm; and the slightly pol-
luted area had less than 0.02 ppm SO2. Morbidity with chronic
bronchitis was observed in 5.9% and 3.1% of male and female
examinees, respectively. Higher morbidity was noted in elderly
males or people from more significantly polluted areas. Severe
respiratory symptoms, persistent cough and phlegm with re-
peated exacerbations, or persistent cough  and phlegm with
reduced  pulmonary function  were more frequently  seen in
these groups.

DETECTION  AND EPIDEMIOLOGY  OF  ATMOSPHERIC
POLLUTION DUE  TO  DOMESTIC  HEATING  PLANTS IN
PARIS.    (Detection  et  epidemiologie  de  la  pollution at-
mospherique  due au chauffage des  locaux a Paris).  Text in
French. Pollut. Atmos. (Paris), vol. 12:33-42, May 1970.
A review of the activities of the Laboratory  for hygiene of the
City of  Paris in the fields  of air  pollution and mortality
statistics since the year 1874 to the present time, is presented.
Early work related to pollution of city air by germs of various
diseases and  its  correlation with increased incidence of these
diseases. In 1900, the effect of travel in congested metro trains
on the propagation of tuberculosis was scrutinized. Systematic
air-pollution measurements  in  a network of air-sampling  sta-
tions were begun in 1957 as a result of the notorious smog dis-
aster in London in 1952. On the basis of data collected in 1957
and  1958, it was estimated that about 52% of the air pollution
by sulfur dioxide in Paris was due to domestic heating plants
numbering  about 20,000. Information is presented on graphic
representation of air pollution data by spots  of different colors
and diameters located at the sampling-station sites, by iso-pol-
lution  curves,  by echinograms and by iso-exposure time,
required  for certain toxic effects to become manifest. A time
sequence of an iso-exposure time graph is shown. The idea of
using the absenteeism of kindergarten-age children as  an in-
dicator of the effect of air pollution on the health of a segment
of the population is mentioned. A very sensitive indicator of
the biological effects of air pollution is deformation of the cell
structure in a cytotoxic atmosphere, a technique originated (in
1964) and developed by the Laboratory of Hygiene of the City
of Paris.

Direct determinations were made in four zones in Genoa, Italy
different in air pollution by means of a questionnaire, to deter-
mine the frequency of respiratory diseases in subjects over 64
years of  age. After considering the possible influence of age,
length of residence, heart conditions, living habits, and previ-
ous  work  activities,  the  percentage  frequency indices  of
coughing, expectoration, rhinitis, dyspnea, and  recent  and
remote respiratory diseases  were calculated. The more impor-
tant comparisons were those  relating to female subjects. A
correlation  was  found between the incidence of respiratory
symptoms and diseases and the extent of air pollution. Lower
indices were found for the data determined in the less polluted
residential area,  especially the frequency of coughing, expec-
toration,  dyspnea, rhinitis, and previous history of bronchitis.
                         A greater mean duration of symptoms and a more frequent
                         summer persistance were found in the more polluted zones.
                         Differences in the  frequency of coughing and expectoration,
                         and rhinitis persisting in the  summer were found between the
                         industrial and non-industrial zones. The quantity of suspended
                         dust and the  sulfur dioxide concentration among the various
                         air pollution indices were well correlated with the data on the
                         frequency of respiratory diseases. Investigations conducted on
                         male groups  confirmed the  results  relating to  women, and
                         showed  a greater frequency  of the cough-expectoration com-
                         bination  and  recent  respiratory  disease  among   smokers.

                         resulting from dramatic incidents of pollution where  permissi-

                         eases as chronic bronchitis emphysema, and primary cancer of
                         lungs and a long-term exposure to pollution at lower concen-
                         trations. The most  serious pollution problem areas in Mexico,
                         outside the metropolitan area of Mexico City, are Guadalajara,
                         Monterrey, and Tepic. Since 1967 the Mexican Department of
                         Health has been setting up stations for continuous sampling in
                         the  area around the capital (Valle de Mexico), where particu-
                         late matter, sulfur  dioxide, and total sulfur content of the at-
                         mosphere can be determined. A study conducted by the Pan
                         American Bureau  of  Health (OSP) July  1967    June  1968
                         makes possible a comparison of pollution measurements in the
                         Mexico  City area  with those of other Latin American cities.
                         Dust measurements indicate that Mexico  has the most serious
                         problems of any of the countries in the group studied (Argen-
                         tina, Brazil, Colombia, Chile, Peru). In the case of Chile (San-
                         tiago) and Argentina (Buenous Aires), the factors created by a
                         temperate climate  (which introduces the problem of  domestic
                         heating) makes comparison difficult. Average values  for Mex-
                         ico  City from October 1967 to June  1968  were 158.2 micro-
                         grams/cu m while  from November 1968  to October 1969 the
                         amount  had been  reduced to 131.8 microgram Both of these
                         figures were higher than those obtained in London and in the
                         United States. Mexico City also has the highest sulfur dioxide
                         rate for Latin America. Measurements from October 1967 to
                         June 1968 showed  an annual average of  95  micrograms/cu m
                         for Mexico City, and 133 micrograms from November 1968 to
                         October 1969, while during the same period the figure for New
                         York City was from 560 to 840 micrograms. Acute respiratory
                         illnesses decreased by 29.4% in urban areas outside the Dis- <
                         trito Federal  between 1964  and 1968,  and by 23.5% in rural
                         areas, while in the Distrito  Federal there was an  18.7% in-
                         crease. Chronic bronchitis,  emphysema,  and asthma showed
                         increased in all areas: 12.7% in urban Mexico 18.9% in rural
                         areas 34.8% in the Distrito Federal.

Experiences in the organized replacement of miners to control
pneumoconiosis in the Ostrava-Karvina region are presented.
The  mine workplaces are classified by law into four hazard
categories according to the hygienic conditions and results of
dust concentration measurements. The dust rate is estimated
gravimetrically by  sampling on Soxhlet filters. To prevent ag-
gravation  of pneumoconiosis, the organized replacement to
less  hazardous areas  is  carried out when the  disease is
revealed.  This replacement  is also effected in  the  case of
healthy  miners, to prevent the development of the  disease.
These cases concern workers younger  than 21 years who have
exceeded the maximum exposur time and workers with X-rays
corresponding to group Z of the international classification of
pneumoconiosis. The maximum exposure time, after which the
miner should be transferred, is determined in each plant ac-
cording  to the hazards of the mine and the pneumoconiosis
rate. It is expected that the preventive replacement of miners
will reduce the rate of new  diseases and reduce aggravations
of existing pneumoconiosis cases. (Author summary modified)

RELATIONSHIP BETWEEN THE TYPE OF WORKPLACE
AND OCCUPATION AND THE DEVELOPMENT OF PNEU-

The  rate of  pneumoconiosis  development, in relation  to the
type of  work-place and occupation, was observed in 1132 coal
miners up to 6 to 10 years after the initial form of the disease
appeared. The rate of development was quickest in the miners
engaged in the  actual mining of coal, slower among the cut-
ters, and slowest among those whose work alternated between
mining  and  cutting.  To  retard the  development of pneu-
moconiosis, work in the mines must be stopped after a finding
of reticulation. If the miner stops working in the mines  only
after a diagnosis of general  nodulation, further developement
of the disease will not be prevented.  The more advanced the
stage of pneumoconiosis  at the time of transfer, the higher is
the frequency of the complicated form of the disease.  No  rela-
tionship was found between  age and pneumoconiosis develop-
ment.  The   prevention  of   pneumoconiosis among  miners
requires a transfer from  the  most hazardous occupations be-
fore the reticulation diagnosis is made. (Author conclusions

CHRONIC DISEASES OF RESPIRATORY SYSTEM  IN THE
AIR  POLLUTED AREA OF KAWASAKI CITY. (Kawasaki shi

10th, Annual Meeting, 1969.)
Kawasaki has about 38 industrial establishments  that produce
much sulfur dioxide emission, and most of them are situated
along the  southeastern sea coast.  This area was  defined  as a
high-pollution area, and the  rest of  the city was divided into
intermediate, light and non-polluted sectors. Out of the popula-
tion  of  about nine million, 300,000  live in the high-pollution
area. In a series of preliminary investigations a sample of  1000
citizens  was questionnaired  concerning respiratory duct and
lung afflictions as well as eye and .nose irritations. They were
also  investigated for past histories of chronic bronchitis. Of
the high-pollution area residents 95%  showed an affliction of
one sort or another. Similar investigations were conducted on
daily laborers, and the results were similar. In addition chest
X-rays were given to the elderly, and 10% of them from the
high-pollution area had an active case of TB which is five time
more than in the non-polluted area. Other preliminary tests led
to the conclusion that chronic respiratory diseases among the
high-pollution area residents are  not negligible, and for these
patients, pulmonary  function test, chest X-ray, EKG,  blood
test, and British Medical Research Council questionnaire were
administered and the results are presently being analyzed.

had  been accompanied by an increase  in death rate due  to
bronchitis and asthma. A random sampling of 3000 patients of
the Internal Medicine Division of the Yamaguchi University
Medical School revealed that since 1962 the number of non-tu-

AIR  POLLUTION EFFECTS  ON THE HUMAN BODY IN
YOKKAICHI.   (Yokkaichi shi ni okeru taiki osen no kenko ni

From 1961  to  1967,  affliction and death rates for Yokkaichi
were studied in order to investigate pathologically  their cor-
relation with air pollution. The annual affliction rate in the
area  was calculated  as the ratio  of the number of medical
cases obtained   from the  detailed  records  of the National
Health Insurance Plan (NHIP) billings to the total number of
people enrolled in  NHIP.  At 10% significance level, correla-
tion was observed between cold - bronchitis and sulfur dioxide
gas, bronchial asthma and settling dusts as well as sulfur diox-
ide,  and frontal eye  disease a settling dusts. Affliction rates
were also compared for Yokkaichi and other control  areas
over the seven year period, and major differences were  found
for laryngitis, cold-bronchitis, and bronchial asthma as well as
frontal eye diseases. In the  polluted area, the frequency  of
bronchial asthma has markedly increased  since  1961. Death

rates  were calculated as three-year  averages ove the seven
years, and polluted areas in Yokkaichi and control areas in the
agricultural regions were compared. In general,  death  rates
were higher in the agricultural areas.  Most of the causes were
the bloodvessel damage in  the  central nervous system, total
TB and  pneumonia.  In the polluted area, deaths  due to
malignant neoplasms were  significant.  Obstructive repiratory
diseases are decreasing in the control area, but are rapidly in-
creasing in the polluted area.

Mining-industrial cities Ube and Onoda are known as  the cites
of  dust   pollution,  and   Tokuyama  and  Nanyo   of  the
petrochemical  industry  are polluted  by gaseous  pollutants.
However, the recent trend in the soluble and non-soluble com-
ponents of the pollutants,  the  seasonal  wind direction, the
decline in the use of coal in Ube and Onoda, and the general
tendency in the industry to  use more and  more petroleum,
have all contributed toward the  increasing similarity in the na-
ture of pollution in the  two groups of cities. In  addition, the
similarity  of the rates  of chronic bronchitis affliction in the
two general areas indicate that it is related to the similarity of
the proportions of soluble  components in the settling dusts,
especially the pH values, in Ube and Nanyo, and Tokuyama
and Onoda. This can be seen  in the  regression line of the
bronchitis affliction rate versus the pH of soluble components,
the data points being taken from all four cities and other major
bronchitis-prone cities as Yokkaichi and London.

The relationship between air pollution and respiratory diseases
in  the industrial  cities of  Yamaguchi  Prefecture  was in-
vestigated. Th general nature of air pollution has been chang-
ing from  settling dusts  to gases  from the  combustion of fossil
fuels, and correspondingly, the relative predominance of as-
sociated  diseases  have  changed  from bronchitis to asthma. In
three  cities,  Ube, Onoda,  and Mine (settling  dusts), the
frequency of bronchitis was higher than in Tokuyama and
Nanyo (gaseous pollutants).  The  frequency of asthma  was
more  or  less the same  for both groups of  cities, but in the
gaseous  pollution  cities, in the areas  where both dusts and
gases are  becoming  more concentrated,  the  frequency of
asthma is increasing. The higher concentration of sulfur diox-
ide seems to be associated  with the increase in the asthma af-
fliction rate. Also, there was  a  significant negative correlation
between  the  frequency of bronchitis  and the soluble  com-
ponents such as SOS and Cl in settling dusts as well as  their
pH. Various data on air pollution such as are caused by set-
tling dusts and gases, and bronchitis  and asthma are tabulated
and statistical analyses of data are presented.

                         The effect of lead poisoning on amino-levulinic-dehydrase ac-
                         tivity was studied by colorimetrically determining the porpho-
                         bilinogen,  which  is  formed by ALA-dehydrase  activity,
                         present  in the erythrocyctes  of  50 subjects with chronic or
                         acute lead poisoning. In 19 patients, no enzyme activity could
                         be identified;  in  the  others,  it  was distinctly  lowered. The
                         results demonstrate that diagnosis of ALA-dehydrase acitivity
                         is a valid test of lead poisoning.

                         The synergism of gas and aerosol was investigated  by means
                         of a simple model of a respiratory tract consisting of a vinyl
                         tube with the inside moistened and a wet tube with  the inside
                         moistened  under a constant condition. The gases used were
                         sulfur dioxide and nitrogen dioxide. For particulates, dusts in
                         ordinary  outdoor air as well as black smoke resulting from the
                         combustion of benzene were used.  The penetration  rate of
                         SO2 increased with an increase in the flow rate  of air through
                         the wet tube or a decrease in  concentration. In both cases, the
                         addition  of particulates further  increased the sulfur  dioxide
                         penetration rate. For nitrogen dioxide, the change in the con-
                         centration or the flow rate of air did not have any appreciable
                         effect on the penetration rate;  the presence  of paniculate
                         matter also did not have any influence on the penetration rate.
                         The aspiration of air through  a glass  fiber filter for a dustme-
                         ter showed that within an hour after aspiration,  the sulfur
                         dioxide in air had the penetration rate of about 100%, but after
                         20 hours,  the rate declined  appreciably. Together with the
                         change in value observed  due to change  in humidity,  the ob-
                         served phenomena indicate  that sulfur dioxide gas was ab-
                         sorbed by the sulfuric acid mist to form small particles, which
                         were subsequently trapped by the glass fiber filter.

and vitamin Bl (200 mg). This small dosage immediately cured
71% of the patients, distinctly improved 19%, and was unsuc-
cessful with only 10%.  In order to prove that this treatment
actually causes an increased secretion of lead, a lead analysis
of the urine was  made for five patients. All cases showed an
increase of lead secretion with the exception of one female pa-
tient.  The people living close to traffic inhale  at least  four
more  kinds of exhaust gases  (carbon monoxide,  hydrocarbon,
nitric  oxides,  tetraethyl lead), which cause headaches as an
early  symptom themselves and which simultaneously reinforce
the toxicity of lead.

Exhaustibility  of the rat  during  a  swimming  experiment,
fatigue of mice during spontaneous physical labor, and muscu-
lar fatigue during electrical irritation of the chewing muscle of
the rat were examined  during and after exposure to carbon
monoxide. Efficiency of the  chewing  muscles was distinctly
decreased by the effects of CO within a concentration region
of 0.025  to 0.125%  vol. After the introduction of  CO  was
stopped,  the decrease in efficiency was reversible for only low
concentrations,  and  then  only  partially, while  permanent
damage  remained  at high  concentrations.   Higher carbon
monoxide concentrations were required to achieve a decrease
in efficiency of the motor system in the peripheral area  than
for deteriorations of the central system. A 1-hr exposure of a
mixture of air  and of 0.05% vol CO significantly decreased the
swimming   efficiency  of  rats.   Running   distances  were
decreased by 1/2 with 48 ppm CO and by 1/3 for 55 ppm.

Although  the  cause-effect  relationship  between ferroman-
ganese production and epidemics of pneumonia in Aosta is not
at all  clear and convincing, no other cause can tbbbe cited to
exp n tttthese  events, unless one would ascribe them to a par-
ticularly  malignant  form of  epidemic. To some extent,  this
malignancy could be  due to the effect of manganese dioxide
fumes and dust inhaled by the population in connection  with
an increased virulence of the  pathogenic germs or, also likely,
a chemical form  of respiratory tract inflammation and a  sub-
sequently increasing development and virulence of  the  bac-
teria.  Morbidity was  similar  during this  period  in the entire
population and there was no  difference in distribution related
to age, sex or profession. It  seemed that even the vegetation
suffered  greatly  in  the area in which the  concentration of
smoke was  particularly  dense.  However,  ferromanganese
production was distinctly most intensive  during the summer
and autumn months while  the highest mortality was always
noted during ae winter months when there was no production.
The gradual disappearance of the epidemic after 1940 may be
related either  to  a  spontaneous decline  in epidemic charac-
teristics or more  likely to the effects of  sulfonamide therapy
combined with a  gradua habituation of the citizens to inhala-
tion of manganese dioxide-lade fumes.

Pathological changes were observed in the respiratory organs
of rats exposed to 50-100 ppm or 700-1000 ppm of sulfur diox-
ide for periods of one day to 25 weeks. Extensive pathological
observation  were made in airways and alveoli by horizontal
longitudinal section of the total lungs with the trachae. In addi-
tion, histological typ of airway epithelium were classified. Air-
way epithelim of exposed rats exhibited disappearance of cilia,
erosion, increase of mucous cells, squamous cell metaplasia,
and hyperplasia.  Also  observed was elongation of epithelial
cells from terminal bronchiole to alveolar walls. Infiltration of
small round cells and proliferatio of collagen fiber were found
in peritracheae,  peribronchi, and peribronchioles. There was
also perivascular infiltration and congestion in  alveoli capilla-
ries, and infiltration of small round cells in alveolar walls and
alveoli. Abscesses progressed from bronchus were noted in the
lungs of rats exposed to 700-1000 ppm  SO2. In general, there
were no marked differences between pathological changes fol-
lowing exposure to 50-100 ppm SO2 and those following expo-
sure to 700-1000 ppm.

The difference  in  incidences of common cold, bronchitis,
bronchial  asthma, pulmonary  emphysema,  lung cancer, and
pneumonia  between   polluted  and  nonpolluted  areas   in
Higashinada and Nada wards of Kobe  were studied. Medical
practitioners in the district selected the patients to  be studied
from their medical charts, and completed the  questionnaires
on  the epidemiological survey of air pollution in Higashinada
and Nada Wards. These two districts were divided into three
areas according to the  degree of air pollution.  Area-AI had a
sulfur  dioxide concentration of more  than 1.0 mg and  an
average amount  of  settling dusts of more than  20 t/month.  In
Area-All, the SO2 concentration was the  same  as in Area-AI;
the amount of settling dusts was 10-20 t. In area -B, SO2 was
less than  1.0 mg and  the  amount of sedimented  dusts was
under 10 t/month. This  district was assumed to be nonpolluted.
The returned questionnaires were 67,483  for the first survey
and 18,274 for the second survey. The sulfur dioxide concen-
tration of  less  than 1.0 mg is not likely to influence the mor-
bidity of respiratory diseases, but for women over 40 who live
in the same area for a long time, there might have a slight ef-
fect. The data show that even at this low level  of sulfur diox-
ide  gas, the combination with dusts does have an effect  on
human health. Comparing the polluted and non-polluted areas,
the  only  symptoms that manifest any significant  difference
were cold-related,  and  there was no  significant difference in
the  frequency of asthma in the two areas.

Analyses made on blood samples from hares shot during the
fall hunting season confirmed the possibility of using hares as
indicators of industrial air pollution and of the presence of cer-
tain pesticides. The distribution of harmful emissions can be
estimated  by  analyzing some  elements of the erythrocytes
(hemoglobin,  hematocrit, and eventually globular saturation).
In general,  the blood values decrease with increased pollution,
except in a few cases of very high SO2 emissions. The pH of
the  urine varies: in  cement-producing areas, it is over 7.0; in
SO2 areas, it is  below 7.0.  A good practical criterion is the
multiplication coefficient calculated from the number of young
and full-grown hares killed. For hares in an area of mixed ash
and sulfur dioxide pollution,  the multiplication coefficient was
30% lower than  for controls. In contrast, the coefficient was
higher by 35% in an  area rich in cement dust. The present in-
vestigations,  which  covered  mainly the influence of  gaseous
SO2 and hydrogen fluoride, point to a decrease in the number
of insects (without an actual decrease in the number of spe-
cies)  with  increasing pollution. The differences in the tax-
onomic  groups are not pronounced: the decrease in number is
almost uniform in all categories.  However,  a  slight increase
was noted in  the Phytophaga in the most polluted zone and in
the  Zoophaga in a less polluted zone.

the teeth were frozen in crystals and mounted on glass covers.
Physical development was carried out with a mixture of gum
arabic solution and silver nitrate. With this method deposits of
lead were demonstrated and their location determined. In tis-
sue sections,  deposited lead sulfides appear as find brown to
black granules afte  physical development. Lead  appears to
have a preference for the small canals in the dentine, layers of
secondary dentine, and interglobular spaces as well as for ce-
ment. The  distribution of th lead  sulfide particles in the in-
dividual dentine  regions also shows a  direct dependence on
metabolism. Similarly, it is possible to  recognize a change in
the distribution of lead sulfide granules  in the region of decal-
cification due to  caries.

PNEUMONIA IN THE AREA OF THE SAUDA FACTORIES
OF RYFLYKE.  Tidsskr. Norske Laegeforen., vol. 49:553-568,
602-612, 1929. Translated from Norwegian. 25p.
                         A description is provided of an investigation in a Norwegian
                         town wherein the residents were blaming a high incidence of
                         pneumonia accompanied by an abnormally high mortality rate
                         on the smoke from a local ferromanganese plant. It is  con-
                         cluded that the function of the plant in the spread of the dis-
                         ease is to provide the point of contact for the  contageous
                         transfer of a highly virulent strain of pneumococcus; no  case
                         could be  presented for causation by the smoke or any of  its
                         constituents. The remedy suggested is innoculation of the in-
                         habitants  and isolation of pneumonia patients.

                         In the past, quantitative  evaluation of an obstruction in the
                         respiratory  passages  depended  on measuring parameters  of
                         pulmonary function, the values of which reflect flow during
                         forced ventilation and are contingent to a great extent on the
                         assistance of the subject. Direct analysis of bronchial flow re-
                         sistance  is no possible  by  means  of a procedure, body
                         plethysmography, which measures  synchronous  respiratory
                         changes in volume of  the lungs  as a change in volume of the
                         whole  body.  Simultaneously,  the  process  measures  in-
                         trathoracic gas volume (IGV), which is significant in the diag-
                         nosis of  emphysema.  Measurements are made while the pa-
                         tient sits  in a narrow,  sealed chamber into which warm, moist
                         air is directed. Chamber pressure and intensity of respiratory
                         flow are  recorded during a complete respiratory cycle, the
                         measurements yielding a closed pressure or 'hackle' curve that
                         describes  the relationship between  alveolar pressure  and
                         chamber  pressure.  Resistance and IGV are read on a nomo-
                         gram. The method  makes it possible to determine  whether an
                         obstruction in respiratory passages is functional (and thereby
                         reversible) or morphologically fixed.

                         and mortality from respiratory tract cancer in ten Polish towns
                         was  investigated. The  statistical analysis did not reveal any
                         correlation between the total amount of atmospheric dust and
                         the death rate  from cancer of the lungs and the bronchi.' Some
                         correlation existed between the  degree of pollution of the air
                         in the investigated cities by aromatic polycyclic hydrocarbons
                         and the death rate from cancer of the lungs and the bronchi.
                         Among the tested towns, the  highest level of these hydrocar-
                         bons was in the atmosphere in Zabrze, Katowice, and Gdansk;
                         in all these cities, the  death rate from cancer ot the lungs and
                         the bronchi was the highest. Warsaw had  the lowest level of
                         aromatic  polycyclic hydrocarbons in the atmosphere among all
                         investigated towns. Simultaneously, Warsaw had also one of
                         the lowest death  rates from cancer  of  the lungs and the
                         bronchi.

Colo., 95p., Oct. 20, 1970.
Ten cases of manganese poisoning were observed from 1949 to
1953 among workers exposed to dust and smoke at a man-
ganese alloy  plant. The length  of  exposure ranged  from  18
months  to 12 years. Clinical findings corresponded to symp-
toms of light  parkinsonism. In the case of two workers, the in-
toxication was manifested by hemoparkinsonism. All victims
were subject  to muscular cramps and uncontrollable  laughter.
Blood  analyses  showed  slight  leukopenia  in five  patients.
Treatment with  2,3-dimercaptopenol ('BAL') or pyrodoxine
was  ineffective. The  difficulties  of  diagnosing  manganese
poisoning are stressed, the  distribution of  manganese  ores
noted,  and studies of  the toxicology and  pharmacology  of
manganese reviewed.  In addition,  symptoms of  manganese
poisoning are detailed and the effects  of manganese  on liver,
blood, and lungs reviewed. To prevent manganese poisoning,
attention should be given to characteristics of manganese ores,
i.e., the percentage of various manganese oxides, the  extent to
which the ores disintegrate, and their content of hepatotoxic
materials. Good  ventilation is essential, as  are periodic ex-
aminations of workers.

As a pan of the  second Omuta City epidemiological investiga-
tion of the influence  of air pollution in August 1966, thoracic
x-ray examination was  done on  the 2626 residents who live in
the contaminated area and in  the  control  non-contaminated
area. Examination of pulmonary function was done  by Peak-
Flow-Meter and Vitalor on the 520 school boys and 527 school
girls (aged 8-12), and  the 1104 mothers (aged 24-55)  of the
school children,  who lived in the present addresses  for more
than five years. The monthly  average of falling soot and dust
and sulfur trioxide concentration in all of the area were 26.5
t/sq km/month, and 0.76 mg/D/100 cu cm PbO2. thoracic x-
ray examination revealed tuberculous changes at a higher rate
of 7.5%  in the  contaminated  area  and 4.2% in the  non-con-
taminated area. The average of the mothers' vital capacity was
higher in the control area; the ratio which did not reach 80% in
the percentage of the estimation was more or less higher in a
part of contaminated area. The  average of PFR showed obvi-
ously a low figure in a part of  the contaminated area. In the
comparison of PFR by  height, it was at the lowest in  a part of
the contaminated area and  higher in  the  non-contaminated
area. The average  figure of  vital capcity in school  children,
both of boys  and girls,  showed a tendency to be smaller in the
contaminated area. It did not always show the parallel relation
with air pollution. PFR in boys  showed a higher figure in the
contaminated area, and the regression line of PFR against the
vital capcity showed a slight difference in the low vital capaci-
ty group; the higher the vital capacity, the lower was the PFR
in the contaminated area. The average of 0.5 second amount
figures by height and figures by height with  MEFR in boys
were higher in the  non-contaminated area. From the  result of
this investigation, the mothers' PFR, school children's PFR,
0.5 second amount, and the expired air flow shown in MERF
were reduced in the contaminated area.

An investigation area of (1) heavy pollution with an average
sulfur trioxide concentration of 0.60  - 0.9 mg/day/100 sq cm
PbO2,  and an average falling soot and dust concentration of
5.81-39.48 t/sq/ km/month and a (2) control area of mild pollu-
tion  with  an average  SO3  concentration  of  0.38    0.59
mg/day/100 sq cm PbO2 and average falling soot and dust con-
centration of 7.79 t/sq km/month were  selected for study in
November 1969.  Interviews  and questions  using a  BMRC
questionnaire  and  simple  pulmonary  function tests  using
vitalor were made for the 290 inhabitants who were chosen at
random from the men or women more than forty years of age
and lived in the areas. There were 93.3% inhabitants who lived
at the present address for more than five years; 98.6% of them
answered the questionnaire. Cough, sputum,  short breath, rest
because   of  respiratory   disease,   and  bronchitis  showed
generally a high rate; compound symptoms showed a low rate.
Men showed a higher rate in almost all items  except short
breath than  women,  but no significant difference was found.
Although there  was  no  significant  difference  between  the
areas, both men and women in the investigation area showed a
higher rate  than the control  area in cough at day or night,
acute increase of cough and sputum, rest because of respirato-
ry disease,  bronchitis, and respiratory  asthma.  The relation
between respiratory symptoms and smoking  was studied only
in men. The smokers showed a higher rate than non-smokers
or former smokers in continued  sputum and short breath of
more than grade three,  and  in compound symptoms  except
cough; but there was no significant statistical difference and
no obvious difference between areas.  In the simple pulmonary
function test, only  2.2%  of subjects showed an abnormal
figure where less than 60% of the rate for one second was ab-
normal;  no  significant difference  could be found between
areas.  Although  the  influence of air pollution is obscure at
present,  the result suggest that a slight influence begins to ap-
pear.

In order to study the relationship between sulfur dioxide con-
centrations in the air and attacks of asthma, 107 cases of the
out-patients with asthma at the clinic  of allergy in the depart-
ment  of pediatrics  of  Juntendo  Hospital were  studied
throughout  1968. Sulfur  dioxide  concentrations  were   in-
vestigated according to the results of the measurements of air
pollution made by an auto recorder reported  by the Bureau of
Capital  City  Development  (published in March 1969). The
frequency of the attacks of asthma was studied on the basis of

hospital cards and diaries recorded by the patient's  family.
The relationship of SO2 concentrations and attacks of  asthma
in the following four  divided  areas  was  summarized on  a
monthly basis: (1) Koto-ward, (2) Edogawa-ward, (3) Chiyoda,
Chuo, Bunkyo, Daito, Shinjuku, Koto, Minato and Shinagawa
wards, and (4) Setagaya, Itabashi, and Edogawa wards. No
correlation was found.  The results did not indicate  that SO2
concentrations in the air were high when attacks were frequent
or that more attacks occurred on the days when SO2 concen-
trations  were  high. Thirty three cases of  infants  living in
Chiyoda, Chuo,  Bunkyo, Daito, Shinjuku,  Koto,  Shinagawa,
and Minato wards where SO2 concentrations were thought to
be  comparatively high were  investigated  on a day when  a
warning against smog was announced or on the following day.
No tendency for attacks of asthma to occur more frequently
on those days were noticed.

Conditions of air pollution, epidemiological investigations, the
findings of medical examinations of the inhabitants and school
children and the state of the patients connected with air pollu-
tion  in   Yokkaichi city were reported.  Falling  dust  has
decreased with every year or remains on the same level; how-
ever,  a proportion of soluble components  is much more than
that of   other  cities,  and soluble  components  have been
acidified  constantly with every year since 1961. Sulfur  dioxide
increased  rapidly from  the end of  1961 to early 1962,  and
remained on the same level afterwards; however, the trend of
increase  has been observed since 1965.  Nitrogen dioxide is
below about one tenth compared with SO2. Sulfuric acid is de-
tected from the  air almost constantly. The incidence rates of
various diseases were observed by means  of receipts of the
National  Health  Insurance for 4 years from 1961. The diseases
which were recognized  to be very related to air pollution were
common   cold,  bronchitis,  front  ophthalmopathy,  bronchial
asthma,  and pharyngitis There  was  high correlation between
the diseases and SO2 rather than falling dust. Furthermore, a
high correlation  was observed among  infants and children in
pharyngitis, and among aged people in bronchial asthma. The
investigation by  means of questionnaires was carried  out on
the inhabitants of over 40  years of age in contaminated aisas
chosen with different pollution levels. The number  of people
suffering from chronic bronchitis and asthma-like attacks in-
creased with the height of the degree of pollution with SO2 in
the area. Medical examinations in junior high schools  in con-
taminated areas also  showed  the  tendency to  obstructive
disturbances. Half of the recognized patients by the Environ-
mental Pollution Relief Law were seen in Shiohama  district, a
high contaminated area. The people wbo had moved to  outside
the city  or non-contaminated  area showed clinical improve-
ment or healing at a high rate after moving out.

                         For investigating the influence of air pollution on the bodily
                         functions of elementary and middle school boys and girls in
                         Kanagaw Prefecture, medical examinations of oto-rhino-Iaryn-
                         gology and ophthalmology  were made by  specialists during
                         May and July, 1968. Selection criteria of contaminated degrees
                         were as follows:  contaminated  area (area I) was where  the
                         yearly average of sulfur dioxide concentration was more than
                         2.0  mg SO2/day/100 sq cm PbO2  and falling  soot and dust
                         amounts  were more than  lOOt/sq  km/month;  and non-con-
                         taminated area (area H) was where SO2 concentration was less
                         than 1.0 mg Sol/day/loo sq cm PbO2 and falling soot and dust
                         amounts were less than 6.0 t/sq km/month. Subjects were 3225
                         boys and girls in area I and 3102 in area II. Examinations of
                         oto- rhino-laryngology  were made  concerning  earwax, otitis
                         media, auris externa, deafness, hypertrophic rhinitis, atrophic
                         rhinitis, other kinds of rhinitis, sinusitis, nasal polyp, deformi-
                         ty of the septum, nasal vestibule disease, nasal vestibule pollu-
                         tion, tonsillar  hypertrophy, tonsillitis, adenoids, pharyngitis,
                         and tracheophony. The items which showed a higher rate in
                         area I and which were significantly different from area II were
                         earwax, sinusitis, nasal vestibule diseases, and nasal vestibule
                         pollution; each prevalence  rate was 13.8%, 8.2%, 3.7% and
                         1.8% in area I, and 4.9%, 1.1% and  0.1% in area II. There was
                         a significant  difference between area I and area II in  the
                         prevalence  rate of  4 items of  oto-rhino- laryngology. From
                         previous reports or conditions of air pollution,  it seemed that
                         school boys and girls in area I had  a larger intake of contami-
                         nant in the upper respiratory tract compared  with  those  of
                         area H; upper respiratory tract or whole respiratory apparatus
                         seemed to be affected in some degree by the air pollution. Ex-
                         aminations  of ophthalmology were  made concerning follicular
                         conjunctivitis, chronic  conjunctivitis, eczematous blepharitis,
                         pseudotrachoma, tarsal cyst, acute conjunctivitis, hordeolum
                         and   trachoma.    Follicular   conjunctivitis,    eczomatous
                         blepharitis,  and acute disease were more  in area I;  chronic
                         conjunctivitis, pseudotrachoma,  and tarsal  cyst were  more in
                         area n, but there was no significant difference between area I
                         and II. The prevalence  of diseases  was the most in Kawasaki
                         area which belonged to  area I, bu it seemed that the difference
                         of  home environment generally caused ophthalmological dis-
                         eases.

                         By  means of a correlation  coefficient, a study was  made of
                         the  relationship between cancer mortality and what are  re-
                         garded as pollution indicators:  the  consumption  of solid and
                         liquid fuels. It was concluded that, generally  speaking, one
                         must consider 'urbanism' in its collective entirety, .rather than
                         singling out the consumption of fuels as a factor representing
                         air  pollution. The  localization  problem for cancer -seems to
                         correlate better with an  'industrial and technological factor'
                         represented by the consumption of petroleum  products. The
                         localizations involved are the lungs in men,  leukemia in men
                         and women, the upper respiratory and  digestive tracts in men,
                         and the  uterus  and uteral cervix in women.  Attempts  to
                         separate the 'pollution'  factor from  the industrial-technological
                         factor were unsuccessful. Results  indicated that the starting
                         point in further study would be the distinction between urban
                         and rural environments and the exogenous factors  that in-
                         fluence these.

In 1969, 30,000 school-children in five cities in Yamaguchi Pre-
fecture  were   given   questionnaires   in  order  to  clarify
epidemiologically the relationship between air pollution and in-
fantile    respiratory   disease.   Common   epidemiological
phenomena  were  observed  between  asthma,  asthmatic
bronchitis,  and bronchitis; it was not clear from the question-
naires alone whether the similarities were due to the  defini-
tion, diagnosis, or classification  of illnesses, or because the
three diseases are actually related. Various statistical analyses
are presented for such items as the correlation between sulfur
dioxide  concentration  and asthma, bronchitis, and  asthmatic
bronchitis,  past history of school children regarding the three
types of ailments, and the frequency distribution of past histo-
ry of the illnesses with age. In order to  clarify the relationship
between the diseases  and air pollution, more multi-factorial
studies have to be  made with the emphasis on  the environ-
ment, cause of illness, and the carrier, based on the correct
understanding and diagnosis of the respiratory symptoms.

AIR POLLUTION AND ASTHMA.  (Taiki osen  to  zensoku).

eases), 28(10): 703-709,  Oct. 1969. 25 refs.
Asthma is  an illness very hereditary in nature, and there are
many inducements  to  asthma. In  the  case  of  air  pollution,
many studies have  shown that it can  be  an inducement for
asthma, but the question of whether air  pollution can be an ac-
tual cause  is yet to be answered. Various characteristics  of
bronchial asthma symptoms  are described and past statistical
studies  on the  group  examination  of factory workers  in
Kawasaki,  for example, are explained.  The study of medical
records  over a period of three years shows that asthma tends
to be related to weather. For example, on days when the tem-
perature  is lowered by more than 3 degrees,  especially on
rainy days, asthma tends to occur more frequently. Also when
there are many  suspended particles in the atmosphere, asthma
attacks are frequent. This is probably because sulfur dioxide is
easily  absorbed  by  suspended  particulates.  Other items
described are the effects of  SO2 gas on respiratory function,
the susceptibility of the respiratory tract,  and the relationship
between asthma and chronic bronchitis.

In order to study pathologically the effect of sulfur dioxide gas
o the human respiratory system and to shed some light  on the
development mechanism  of  respiratory disorders, dogs were
studied and clinical experiments were conducted. At high con-
centrations (30-300 ppm) of SO2, the dogs all died within 3-30
days and bronchitis, blood congestion in  the lungs, and lung
edema  were observed.  At  low  concentration  (2-3  ppm),
thickening of alveoli walls with pneumatosis and interstitial
pneumonia were diagnosed, and there was no bronchitis. With
respect to smoke concentration at a Ringelmann chart level of
2-3, the dogs had a high degree of blood congestion of the
lungs and died within 2-5 days. Sulfur dioxide gas increased
the resistance of the human respiratory tract over time, but
the phenomenon was reversible. The degree of resistance in-
crease was larger for non-smokers. There was no definite cor-
relation between the infant  bronchial asthma and infant tu-
berculosis and suspended particulates. The  examination of the
Yokkaichi asthma  patients showed that there was a marked
decrease in one-second rates and the appearance of pulmonary

Investigations of the living environment and respiratory dis-
ease were carried out on 5284 patients who visited medical or-
ganizations in Amagasaki for a main complaint with respirato-
ry symptoms on August 27,  1969. Results showed an affirma-
tive opinion  to  the present states as 57.6% and  a  negative
opinion as 41.7%. According to a residential analysis between
highly  polluted and lowly  pollute districts, the negative opinion
was 73.0% in a highly polluted district and 19.2% in a lowly
polluted  district among the over 40 age group. The rate of the
patients per 100,000 inhabitants over 40  years old was 1442.7
in a highly polluted district and 693.1 in a  lowly polluted dis-
trict, and there was a marked difference betwee the two dis-
tricts.  The inquiry by a round-postcard with questionnaires
was performed with respect to  1285 persons over 40 years old
who were the  inhabitants of Kuise-Kajigashima  and Tsukiji
districts where  the concentrations of  sulfur dioxide were high
(the former  was  3.89 mg/day/100  sq cm;  the  latter, 4.80
mg/day/sq cm),  in order to  find a crude prevalence rate of
chronic bronchitis. The return rate  of the questionnaire post-
cards was almost 100%, an the crude prevalence rate of symp-
toms was 9.0% at Kuise-Kajigashima district and 11.1%  at
Tsukiji district.  The prevalence  of  symptoms in males was
considerably higher than in female. However, no clear causal
relation could be found as to the frequencies by age and the
smoking habit.  Oral test based  on the BMRC  standard
questionnaire was carried out on the patients who complained
of  coughing and sputum  in the questionnaires; the rate  of
agreement between the results of the oral  test and question-
naire was 95%. The corrected  prevalence rates of symptoms
were obtained from crude prevalence by correcting the gap
between distributions of the patients by sex, age, and smoking
habit. These corrected  prevalence rates were 9.1% at Kuise-
Kajigashima district and 11.0%  at Tsukiji district. Physical ex-
amination,  respiratory  function test,  roentgenographic ex-
amination, examination of sputum, and electrocardiography
were carried out in order to justify the above investigations.

AIR POLLUTION TRANSLATIONS
A study was undertaken to analyze clinical characteristics of
so- called 'Yokkaichi asthma' and clarify the disease state of
chronic non-specific lung disease frequently  observed  in the
Yokkaichi area This area is a center of petroleum industry and
known to be highly air-polluted with sulfur dioxide and other
unknown irritating gases The study was based on  120 patients
who were referred for respiratory symptoms during the  period
June  1967  to December 1968.  These patients  had been  re-
sidents at the highly air-polluted  area for more than 3 years
and had  symptoms of  chronic obstructive lung disease. One
hundred twenty patients consisted of 59 males and 61 females.
The age ranged from 16 to 83 years, but the majority  of the
patients (95 out of 120) were older  than 40 years old.  Symp-
toms of chronic bronchitis were noted in 55.8% of the  cases,
these of asthma attack  in 70.8%. And symptoms of these two
disorders coexisted in  35.0%  of the cases. The increased in-
cidence of these patients seemed  to be closely  related  to the
elevation of air pollutants at the area. Seasonal exacerbations
of symptoms are also  noted  when  the area  is more air-pol-
luted. Thirty nine  out of 120 patients had a previous history of
allergic disorders  and 26 had allergic family  history. Allergic
skin reaction (using house dust) were positive  in 18 among 119
cases tested. These figures are lower than seen in patients with
bronchial asthma in other areas. Increased eosinophils in blood
and sputum were noted  in 33 out  of 104 and  25 out  of 87,
respectively. Fifty eight out of 107 patients had sputum  expec-
toration of more than 10 ml for 24 hours. Acetylcholine  inhala-
tion test (using 1000 micrograms or less) was positive in  10 out
of 51  patients when judged by EFV1 only and in 31 out of 55
patients when judged by EFV1 and/or respiratory resistance.
In chest roentgenogram, inflammatory  and  emphysematous
changes were frequently noted. In  pulmonary function tests,
many  cases  showed  an obstructive  pattern,  an  elevated
respiratory resistance and a poor response to bronchodilator.
Based on  the above  clinical observations and diagnostic stan-
dards of chronic nonspecific lung  disease stated by the  Amer-
ican Thoracic Society of 1962, 'Yokkaichi asthma'  can be clas-
sified into 4 groups of known disease categories 1) 55 cases of
bronchial asthma; 2) 36 cases of chronic bronchitis, 3) 21 cases
of bronchial asthma  with chronic  bronchitis; 4)  8 other cases.
In  younger  age  groups, bronchial asthma  (group 1) was
predominant. In groups older than 40 years of  age, bronchial
asthma (group 1), chronic bronchitis (group 2) and coexistence
of these (group 3) were observed  in  38,  31 and 20  cases,
respectively.

by  Air  Pollution.  1967.  25  refs. Translated  from Japanese.

The  defensive structures of the  lungs,  including the  airway
mucosa (ciliated epithelia and germinal cells),  the tracheal and
bronchial lymphogonia, non-striated  muscles and elastic  fibers,
and lymph follicles, are reviewed in  relation to the morphology
of various chronic  lung  diseases  and possible  associated ef-
fects with air pollution. The occurrence of dust  inhalation dis-
eases depends on the  composition, size,  concentration, and
properties of the  particles; the victim is affected according to
his sensitivity, the intensity and duration of inhalation, and ex-
istence of other respiratory problems. Particle  size  is an  impor-
tant  factor; large particles are likely to be held in the nasal
cavity and larynx, but  smaller ones of up to 100 micron can
pass through the respiratory tract to the air vesicles. Particles
                         accompanied by sulfur dioxide or other toxic gases tend to set-
                         tle far more than when inhaled alone. Aspects of anthracosis,
                         or pulmonary  deposition of carbon dust,  as a morphological
                         disease  caused  by  air  pollution,  are  discussed,  including
                         fibrotic changes, age factors, emphysematous changes, charac-
                         teristic distribution of deposits in the lung, and the  course of
                         carbon dust through the air vesicles into tissue.

                         In the period  1962-1967, the daily variation of death rate in
                         Osaka Prefecture  was  investigated. 'Excess  deaths'  was
                         defined  as the number of deaths  when the three-day  average
                         death rate was higher than the 15-day average plus one stan-
                         dard deviation. Data were studied to see if there were any ex-
                         cess deaths in the outlying agricultural area within  the three-
                         day period in which there were excess deaths  in Osaka (city).
                         When there were no such excess deaths,  then the deaths in the
                         city  were  termed the metropolitan  type. Other terminologies
                         were similarly developed for different types of deaths, in all
                         cases comparing  the agricultural and  metropolitan  sectors.
                         Statistical analyses were performed to find the  various correla-
                         tions between  continuous three-day long pollutio due to sulfur
                         dioxide over 0.15 ppm or suspended dusts over 0.75 mg/cu m
                         and  excess deaths in that period. Looking at the deaths by
                         various  types  of illnesses, deaths due to circulatory ailments
                         fluctuate similarly to the deaths due to illness in general. But
                         deaths due to respiratory diseases do not always follow the
                         pattern.  Respiratory illness  deaths other  than  TB  and
                         neoplasms are not always covariant with total deaths, but they
                         frequently increase  in periods when excess  deaths  are ob-
                         served in one or more  of the three sectors of the Osaka
                         metropolitan area.

                         Although  the degree of air pollution in Nagoya as a whole is
                         still  low,  the  situation  in  the  industrial area of the city is
                         deteriorating. This was demonstrated by the results of a  sur-
                         vey  of the health effects of waste gases from petroleum com-
                         bines and other sources. In the polluted area, there were in-
                         creased deaths due  to respiratory  diseases among men  and
                         women over 70. The correlation between the male death  rate
                         and  sulfur dioxide concentrations was 0.60-0.70 for men over
                         50.  Symptoms of respiratory infections were one and one-half
                         to two  times  more  frequent than in nonpoliuted areas,  and
                         there were more individuals who  caught five or more colds a
                         year. Women  40-60  years old who  had  lived  in the area for
                         more than five years showed reduced lung function. In addi-
                         tion, the polluted area had increasing infant mortality rates in
                         contrast to the reduction noted for other areas. Residents of
                         the industrial area complained mainly of odors and  were  able
                         to identify their exact sources. The  residents appeared to rely
                         on  the  national and local governments for  a solution, not
                         realizing that they themselves could initiate action.

Qualitative  hemoglobinopathia  and  thalassemic  syndromes
have become very frequent in the Paris region due to immigra-
tion of workers  of Mediterranean or African origin, working
under conditions such as exposure to benzene, lead, or ioniz-
ing radiation The irregularities most frequently discovered are
hemoglobins S  and C  on the one hand, thalassemia on the
other hand. These red blood corpuscle irregularities sometimes
pose diagnostic problems because of the presence of  red blood
corpuscles of basophilous granulations in lead poisoning and in
thalassemic  syndromes. The existence of a  hemolytic process
and  aplasic attacks,  in  the  course  of  different  toxic
hemopathia  and in  hemoglobinopathia,  has  lead  numerous
authors  to  eliminate  the subjects  carrying hemoglobin irregu-
larities from any work which could possibly involve the danger
of exposure to a hemotoxic substance. Comparative studies of
toxic environment and hemotological functions of subjects car-
rying  red blood  corpuscle irregularities would be desirable in
order to justify  the professional classification of populations
where red blood corpuscles variations are numerous. (Author

Sept. 1969.
The prevalence of chronic bronchitis 13,100 persons 40 years
of age or more who lived in six districts in Osaka was theoreti-
cally examined.  The equation of  the prevalence was derived
from age, amount of cigarettes smoking, and degree of air pol-
lution. Values calculated from the equation  were compared
with actual ones.  The diagnosis of chronic bronchitis  was
based on Fletcher's  definition. The  equation  derived  from
amount  of  smoking and age was y equals 0.0001 .3N(x  minus
20) squared (I) where N is the amount of smoking per day; x,
the age; and y,  the prevalence of chronic bronchitis(%).  The
equation derived from  sulfur trioxide content, as measured by
the PbO2 method,  was  y, equals  1.94 alpha plus 0.71  (II)
where alpha is SOS  content;  y the corrected prevalence. To
exclude  the  influence of smoking and age on the prevalence of
chronic  bronchitis,  these values were  corrected to standard
values,  and the  prevalence  calculated  from  them   was
designated   corrected  prevalence.  The  equation  of  the
prevalence of chronic  bronchitis, y equals  0.0001 .3.N(X-20)
squared plus 1.94 alpha minus 3.18, was calculated from equa-
tions I and  II where for female nonsmokers N equals 4; for
male nonsmokers equals N equals 8; for 1-10 cigarettes ;day; N
equals 10; for 11-20 cigarettes/day, N equals 20; more than 21
cigarettes per day N  equals 30. The difference between calcu-
lated and actual values was 0.2%. The minimum value of alpha
is discussed.

The  relationship between  weather (fine, cloudy, rainy) and
death rates was examined by classifying 42,293 deaths accord-
ing to date of death, sex, age, and cause of death. The death
figures were for Tokyo residents who died between January 1,
1962  and  December 31, 1962. In the examination, the death
rate  of 100,000  population/day was  sought  and an  average
daily death rate (i.e., a death rate index) according to weather
category was obtained. Death rates in terms of weather were
highest  on fine days and loest on rainy days. Death  rates  in
terms of age were higher on fine days than on rainy days ex-
cept for the 35-45 yr group. Death rates were higher on cloudy
than on rainy days, excepting 5-20 yr and 35-45 yr groups, but
lower than on fine days. Death rates in  terms of sex, judged
from weather were always  higher among males especially
among  young and  old men.  As to death rates  in terms  of
causes, 81.37% had higher rates on fine and cloudy days. The
death rate increased when fine weather continued to  prevail
but  decreased during extended  periods of cloudy or rainy
weather. Deaths from bronchitis and bronchial asthma  over
fine  days  of clear weather were more than twice as high as on
rainy days while  deaths from influenza  were seven  times  as
high. The  analysis of the variations of temperature in terms  of
weather indicated that the temperature range/day and  the am-
plitude  of temperature are greatest on fine days and that on
fine  days, the temperature is lowest in the  hours (1-6 am)
when the  physiological faculty of man is  lowest. These factors
explain  the high rates on death fine days.

Immuno-biological reactivity of the organism is controlled by
general  physiological principles, and the state of the  nervous
system is  a factor of considerable importance in general immu-
nogenesis  and in specific immunity manifestation. It is possible
for the lowered immulogic reactivity of the organism  resulting
from some industrial poisonings. It is known that an anti-infec-
tion  immunity can  be hereditary,  and individually  acquired
means of  adaptation which resists the entrance into the organ
of microbes and viruses,  their proliferation, and the deleteri-
ous  effects  of their products of elimination.  Such means  of
adaptation or barriers are presented by  the skin and mucosa,
inflammation,  phagocytosis, the reticulo-endothelial  system.

the lymphatic tissue barrier functions, humoral  factors,  and
the organism's  cell reactivity. It is believed that each of the
barriers can  be disturbed  by  the effects  of  given  poisons.
Results of experiments  and clinical  observations found in
literature present evidence of the relation existing between the
effects of some industrial poisons and the  fall in the bacter-
icidal potency of blood serum. It is emphasized that in the sum
total of the barriers' action as a phase of antibacterial immuni-
ty, they manifest a variety of mechanisms,  one of which may
be synergistic.  Of particular interest  are  antibodies which
change the microbes in the direction of involution,  lowered
virulence, and  susceptibility to phagocytosis.  Under present
day conditions  intoxication with low doses  or  low concentra-
tions of the toxic agent are encountered most frequently.

The effect of carbon monoxide in ambient air was studied on
two groups of auto mechanics: smokers and nonsmokers. The
experimental  conditions  and  methods were the  same  as
described in an  earlier paper. The average age of the examined
workers was  28 years, 68.9% of whom were between 17  and
30 years. Blood pressure in the  examined  workers  was 29%
higher  than in  a control  group. The carboxyhemoglobin con-
tent in the blood of smokers was on the average 2.38% higher
after exposure to CO-containing air. Among  nonsmokers, there
was a 1.26% increase.  In 4.4% of the smokers and 6.4% of the
nonsmokers,  the number of red  blood corpuscles was below
3.5  million.  Polycythemia  was  observed  in  16.2%  of  the
smokers  and 10.7% of  the nonsmokers. Hyperchromia was
also very frequent.

STUDIES  ON  CHRONIC  BRONCHITIS--EPIDEMIOLOGI-
CAL SURVEY (2ND REPORT). (Manseikikanshien no  kenkyu-

In 1967, an epidemiological survey on chronic bronchitis was
carried out among 7817  male post-office workers in Tokyo,
Tsurumu,  and  Kawasaki. The  results were compared  with
those of the previous study in 1962. A questionnaire was filled
by each employee; the responses were verified or amended by
a personal  interview with a doctor or trained nurse. Where
necessary, an auscultation and percussion were performed. In
diagnosing chronic bronchitis, the standards of Fletcher  and
Fujita  (persistent  cough  and phlegm  lasting more than  one
month  and occurring  every year for mory than two years)
were applied. Of  those  surveyed, 20.6% and 5.8%  had the
symptoms  of phlegm  and  coughing,  respectively.  Chronic
bronchitis in  accordance  with Fujita's standard was recorded
for 8.2%  of the subjects twice as high as  the percentage in
1962. However, with respect to gasping,  there was  little  dif-
ference between the two tests, symptoms of chronic bronchitis
in accordance  with  Fletcher's  standard were exhibited  by
                         about 60%  of the subjects, which is in accord with Fujita's
                         standard. The rate of agreement between the two standards in-
                         creased   with  increasing  age. The  incidence  of  chronic
                         bronchitis was greater among  employees working outside  or
                         living in center-city  and  industrial areas. In each of  the three
                         cities, levels of gases such as sulfur dioxide,  nitric oxide, and
                         nitrogen dioxide  had increased since 1962. The observed in-
                         crease in the incidence of chronic bronchitis is considered  to
                         be closely connected with the increased levels of pollution.

                         children in Chiba Prefecture. Children in  polluted areas tended
                         to have  more frequent colds than those in  control area, espe-
                         cially one-yr olds and three-yr olds. The difference was signifi-
                         cant. In the control  area, children caught fewer colds as they
                         grew older. This was not true  of pollution areas. Among pri-
                         mary school children in Ichihara City, 3.3%  of the boys and
                         2.6%  of the girls (total, 2.95%) had asthma. In Chiba City,
                         0.75% of the boys and 0.36%  of the girls (total, 0.56%) had
                         asthma in 1964. In 1968  the figures were 1.56% for boys and
                         0.76% for girls, (total 1.17%).

                         Daily death figures  from April 1966 to March 1969  were ob-
                         tained from 23 wards of Tokyo. Delta death-15dma (the dif-

                         the data revealed that the correlation between daily deaths and
                         the degree of air pollution was not high in  general; no marked
                         monthly tendency was present in the correlation between  15
                         dma and the degree  of air pollution. On the other hand, a sig-
                         nificant  correlation  was observed between daily deaths and
                         temperature; the highest correlation was observed in August
                         between ISdma and  temperature. There was no significant dif-
                         fernce between the correlation of delta death -ISdma vs tem-
                         perature and the degree  of air  pollution for the same day, for
                         one day, two day, and three day lag.

EPIDEMIOLOGICAL STUDY OF  CHRONIC  BRONCHITIS

Levels of air pollution in Osaka were investigated according to
the British Medical Research Council questionnaire. A total of
34,209 male and female  inhabitants over forty  years old and
living in nine areas of varying air pollution received question-
naires. Respiratory function tests by oral  diagnosis, chext X-
ray tests,  and vitalor  were performed. Return rates of  the
questionnaires  were 80.8  92.5%.  The incidence of  chronic
bronchitis in both  men and women increased with increasing
age and the amount of smoking (the incidence in  those who
smoked more tha& 21 cigarettes daily was three or four times
as high as for nonsmokers of the same age). A higher rate was
shown in an area  of high sulfur dioxide concentration. How-
ever, there was no correlation between rate of incidence and
amount of falling soot. Model expressions to estimate the in-
cidence of chronic bronchitis from age, the amount of smoking
and levels of air pollution, and also the incidence of obstruc-
tive disorders in those suffering from chronic bronchitis from
their age and the amount of smoking were  obtained. Estimated
values and actually measured values for both incidences were
compared. The correlation  coefficients were  0.98  and 0.97,
respectively. The incidence of obstructive disorders was stu-
died by dividing 2350 subjects who answered the questionnaire
into  3 groups:  those with chronic bronchitis (group I), those
with  injuries  other  than chronic  bronchitis (group II),  and
those who showed no  subjective  symptoms such as coughing
and sputum (group III). Rates decreased in the order of group
I, II,  and III. In each group, the incidence became higher with
an increase in age and the amount of smoking.  The results of
this  investigation  were compared with those  for  Yokkaichi.
Qualitative differences in air pollution ip both areas have a dif-
ferent influence on the incidence of chronic bronchitis.

Tokyo is unique in that its population density is  the greatest in
the world; that 25 years  ago, when home-heating was not  de-
pendent upon coal, there was no air pollution, and that air-pol-
lution  is now on  an unprecedent scale. Information was col-
lected from daily  death records and a correlation with air pol-
lution indicators (sulfur dioxide and dust) was sought. The  Air
pollution index in Tokyo equals 9.056 times SO2 concentration
(pphm) power 0.631 + 5 times dust concentration (mg/cu  m).
Among people over 50 there are more deaths in  winter than in
summer. This seasonal change in mortality rate suggests  that
temperature is  the biggest factor among environmental condi-
tions. Daily mortality rate had only low correlation with  fac-
tors  of air pollution (SO2, dust,  air pollution index) and no
result suggesting a causal relationship was  obtained. There is a
positive correlation between mortality rate and  high tempera-
ture,  but it could  not be established how much air pollution
contributed to winter mortality  rates. Further research is
necessary  on direct cause  of death,  contributing  cause of
death, the area where death occurred, and residence. In addi-
tion,  representative  measuring cites  should be  established
throughout Tokyo to determine the relation between SO2 and
dust and other pollutants and other meteorological factors.

Based on data obtained from November 1962 to October 1967,
the relationship between air pollution and the variation in the
number of deaths in Osaka Prefecture was investigated. The
city of Osaka was designated as the polluted area and subur-
ban Sonoda as the control area. Deaths (not due to external
causes) increased when temperature decreased  and degree of
pollution was high. The deaths also depended on the absolute
level as well as the change in the level of pollution. Deaths in-
creased not only when sulfur dioxide concentration was  over
0.1 ppm, but also at lower concentrations when the change in
concentration  was drastic.  Similarly, deaths increased  when
suspended dusts exceeded 0.5 mg/sq m or at lower concentra-
tion if change in concentration was rapid.

Residents  over 40 years of age in the five cities of  Ube,
Onoda, Mine, Tokuyama, and Nanyo of Yamaguchi Prefecture
were surveyed according to the BMRC method. In the primary
survey, for all cities except Mine, a  positive correlation was
observed between sulfur dioxide concentration  (mg/lOOsq cm
PbO2) and the frequency of one type or another of respiratory
illness,  pulmonary function, and SO2 concentration. Similar
results were obtained for settling dusts and chronic bronchitis.
In addition a study of smokers and  nonsmokers showed that
smoking is not unrelated to respiratory diseases. However, in
the secondary survey, there was a significant  difference for
respiratory illness of  one  kind or another between smokers
and nonsraokers, but no significant difference for those having
^missionary damage. For polluted and nonpolluted areas, there
was  a significant difference between  the  three types of in-
dividuals:  those having one type or another of respiratory dif-
ficulty,  those  having pulmonary function damage, and  those
having chronic bronchitis.  It is concluded  that  the effects of
ah- pollution cannot be satisfactorily described by  comparison
of polluted and nonpolluted districts  alone; at individual dif-
ferences in smoking habits must be taken into account.

Based on National Health Insurance records for the  residents,
statistics were  compiled on  the  common cold, bronchitis,
bronchial asthma, pneumonia, laryngitis and pharyngitis, ton-
silitis, and  emphysema. Tsurusaki industrial  area  (0.03 ppm

The effects on guinea pigs of a long-term repetitive exposure
(46 times  over 23  weeks)  to  sulfuric  acid mist  were in-
vestigated.  Sulfur trioxide  evolving from heated  acid was
diluted by moist air and aerosols over 1 micron in  size were
removed by an impactor  with an impinger. The average con-
centration measured by an electroconductivity method was 8.5
mg SO3/cu m. Albumin was given to some  of the animals.
Pneumatograms were recorded by means of a kymograph, and
changes in  the number of acidocytes in 500  leukocytes  of
blood samples was noted. The pneumatograms showed that for
some animals, dyspnea became more severe as the number of
exposures  increased. For those given  albumin, anaphylactic
dyspnea was observed. An increase in acidocytes was also ob-
served, although there were individual differences. Blood con-
gestion in lungs as a result of SO3 exposure was  also noted.

The  correlation between respiratory diseaes,  especially the
frequency  of asthmatic attacks in infants (3-year-olds), chil-
dren (6-12 yrs), and adults (over 40) and air pollution in the ci-
ties of southern Yamaguchi  was studied. In the past six years,
infant morbidity  has increased in Nanyo. There was positive
correlation between  the frequency  of respiratory illnesses and
eczema  and sulfur trioxide concentration. For Onoda, Ube,
Tokuyama,  and Nanyo, the frequency of asthma and other
respiratory  illnesses was high for children in first and second
grades and  decreased  with increase in  grades. Bronchitis and
asthma were especially high in the urban areas. The frequency
of respiratory diseases of children in  the 31 districts of the
four  cities  had a statistically significant correlation with  air
pollution. For the adults, the frequency increased with increas-
ing age.

                        pupils in Yokohama. The samples were divided into five areas
                        delimited according to the isoquants of sulfur trioxide concen-
                        tration.  The actual response rate  was  66.1%,  although  the
                        general  response rate was 81.5%. There was no  correlation
                        between SO3  concentration and susceptibility  to  cold, but
                        clear relationships  were seen between SO3 concentration and
                        sore throat, eye irritation, asthma attacks in the past year, and
                        susceptibility to rashes and allergic reactions. Similar  results
                        were obtained for SO3 and respiratory illnesses such as infan-
                        tile asthma. Data according to the degree of pollution, age, and
                        sex are tabulated for various items.

                        Residents of the commercial-residential  area of Saganoseki,
                        adjacent to a copper refinery with a 295-m stack, were inter-
                        viewed according to the BMRC method. The  sample was 1257
                        residents, excluding highschool students and younger children;
                        the response rate was 82.9%. Items on the  questionnaires per-
                        tained to  protracted  (about  three months) annual coughs;
                        coughing and phlegm  occurring since  two or more years ago;
                        bronchial  afflictions in the last three  years  and past and
                        present asthmatic attacks. The response rate for each item was
                        classified according to sex. The results show that many people
                        are suffering from the respiratory symptoms  due to sulfur
                        dioxide  gas, and that morbidity in the area in almost as high as

                        All ten  year old children  who lived in the areas of Kladno,
                        Bustehrad, and  Zlonice  in Bohemia since  their  birth were
                        medically  examined  and  their  past  history  of  illnesses
                        recorded. The results were grouped according to the environ-
                        mental  conditions  under which  these children lived. Three
                        categories were established; group I, areas with a dust fall of
                        over 500 tons per sq km per year and an average sulfur diox-
                        ide concentration around 0.5 mg/cu m, group  II with a dustfall
                        of  150-500 t/sq km/ year and an SO2 concentration of up to
                        0.15 mg/cu m,  and group III with a dustfall up to 150 t/sq

km/year and an SO2 concentration of up to 0.05 mg/cu m. It
was shown that children living in very polluted areas have re-
tarded growth and a greater morbidity rate for respiratory dis-
eases exist. The reduction in ultraviolet radiance from dusti-
ness and smoke in the air can cause a change in the form of
symmetry of  the thorax and faulty comportment of the body.
Appreciable differences were found with children from groups
I and II,  compared with group III, with regard to erythrocytes
count, hemoglobin values, color index, number of leucocytes,
lymphocytes,  and eosinophiles. There was no difference in
serum protein level in all groups,  and the rate of infectious
diseases was practically the same in all three groups. Suppres-
sion of dustiness by using water curtains when dumping slag,
the need for greening of older slag dumps, the general projects
of dedusting and desulfurization of air, and increased electrifi-
cation of interplant transportation are needed.

THE  CLINICAL  ASPECTS OF GRANOSAN  POISONING.
Inst. of Hygiene of Labor and Industrial Diseases,  Leningrad
(USSR), 9p. Translated from Russian.
Several cases of poisoning due to the accidental use in food of
grain  treated with ethylmercurychloride were diagnosed among
families  of collective  farm  workers.  The  clinical  picture
presented by  the disease was similar to that found  in diethyl-
mercurophosphate  poisoning:  patients  exhibited  gastroin-
testinal disorders, marked adynamia, general exhaustion, and
functional disturbances of the central  nervous  system. The
presence of  the  disease was confirmed  by  the continuous
excretion of mercury  in urine. A  gradual improvement in the
condition of the patients was noted following intravenous in-
jection of glucose with vitamins Bl and C and  subucaneous in-
troduction  of unithiol,  a new synthetic  preparation  recom-
mended as an antidote in cases of  arsenic and mercury poison-
ing.

THE BEHAVIOR OF  DELTA-AMINOLEVULINIC ACID AND
OF  PROPHOBILINOGEN  AFTER  GLYCINE  LOAD  IN
SATURNISM. Med.  Lavoro (Milan),  S8(331):364-369,  1967.
Translated from Italian.
Because  other  tests  are  not always conclusive  indicators of
minor lead intoxication, a study was made of the behavior of
delta-aminolevulinic acid (ALA) and prophobinogen (PBG) in
saturnism, before and after glycine load. Prior to glycine load,
two of the  10 cases studied had ALA serum values above the
maximum normal limit and nine had ALA urine values above
maximal  normal limits. After  glycine load, a noteworthy  in-
crease of the serum  and ALA values was  observed in  all
cases. No changes in PBG were found. In 10 normal subjects,
no pathological ALA and PBG increases occurred in either
urine  or  serum. It  is concluded  that  glycine load not only
makes an  already  existing metabolic  change increasingly
evident, but also permits the documentation of the changes in
those cases of saturnism for which preliminary analyses failed
to demonstrate any ALA changes.

EXPERIMENTAL BRONCHITIS PRODUCED  BY  VARIOUS
AIR  POLLUTANTS.  (Bronchites experimentales par drivers

Pathol. Respir. (Nancy), vol. 5:485-504, 1969. 70 refs.
A study conducted in England with workers over 45 years of
age showed that absenteeism and mortality due to  bronchitis
occurred at a higher rate with increased sulfur dioxide pollu-
tion. These studies also indicated a relationship between mor-
tality from bronchitis and the dust content in the air. Another
study conducted with English postal employees working out-
doors,  revealed  an increased incidence of bronchitis during
periods of fog  and cold  weather. Other  aggravating circum-
stances in connection with bronchitis include tobacco smoking,
and exposure in industrial plants to toxic gases and chemical
irritations, such as  chlorine, ammonia, and  sulfurous an-
hydride.  T determine the ill effects  of air pollution on the
respiratory system, tests were made with animals in  whom ex-
perimental bronchopneumopathies were induced under con-
trolled conditons.  Two  identical chambers  were  used  into
which  an equal number  of  a species  of animals of the  same
age sex and weight were placed for a period of time. The in-
side temperature and humidity in the chambers were kept at
equal values. In one chamber a normal atmosphere is main-
tained  whereas  pollutants are introduced into the other cham-
bers. Both groups  of animals are periodically examined. The
dusts and chronic effects of the exposure of various animals
to seven groups of pollutants were reported. The animals used
were rats, mice, dogs, rabbits, hamsters, and  guinea pigs. The
seven  pollutant groups were  sulfur dioxide,  various nitrogen
oxides, ozone,  dust, tobacco smoke, automobile exhaust
gases,  and aerosols. A great variation of effects of the  same
air pollutant on  different species of animals studied was found.

When  sulfuric acid gas  emissions increased due to increased
consumption of petroleum fuels, the problem of suspended
dust was overlooked although it is emitted in great quantities
from the burning of such fuels. The dust is 0.1-10 microns in
diameter, and stays aloft in the atmosphere from a few hours
to a few years. When heavy oil is burned 48-95% of the dust is
less than 10 microns in  size. About 62-80% of the dust from
automobile exhaust gas  is less  than 2.0 microns. The 0.1-1.0
micron particles are likely to  be inhaled into  the lungs and
retained there. The rate  of deposition is reported to be about
53%. It is also reported that when dust is 200 micrograms/cu m
for the 24 hour average, there is a high incidence of respirato-
ry disease complaints the following two days. Even when sul-
furic acid gas is about 0.01 ppm, if the  dust concentration is
also high, ther are many complaints from respiratory disease
patients. When smog continued for  four  days in December
1962 in Osaka,  the dust  concentration  averaged  more than
1000 microgram/cu m a day, and there was and an increase in
the mortality rate. The sulfuric acid gas during this period was
lower  than the period before of after.  When  there is a high
concentration of unsoluble substances in the dust, the  mortali-
ty rate from bronchitis increases. When  measures are taken to
decrease the concentration, the mortality rate decreases mar-
kedly.

AIR POLLUTION TRANSLATIONS
With the random selection of high and low air pollution areas,
a higher rate of chronic bronchitis is  always  found in highly
polluted  areas. In non-polluted  areas,  the  rate  of  chronic
bronchitis among male nonsmokers is  1% and among smoker
15%; in heavily polluted areas, it is 7%  for non-smokers and
20% for smokers. As a study  in Philadelphia shows, the mor-
bidity rate is correlated with the wind direction, wind speed,
smoke  content, participate concentration, and components  of
sulfur oxides.  A negative correlation exists between air tem-
perature and morbidity. However, none of these factors alone
correlates with  the  morbidity.  Sulfur  dioxide affects the
bronchi only  in extremely high concentrations.  Workers can
inhale 5 ppm SO2 for eight hours  per day without effect, while
1 ppm  SO2 in the atmospheric air causes an increase of the
bronchitis rate. A  clear relationship also exists between the
rate of lung cancer and the degree of air pollution. Carbon
monoxide which is known as  a dangerous toxic is present in
the atmosphere in only small concentrations,  even  with heavy
air  pollution   caused  by  smoke and automobile exhausts.
Another disease which is strongly correlated with air pollution
is asthmatic bronchitis. Some cities are known because of their
high bronchial asthma morbidity,  such as New Orleans asthma
and Yokohama disease. The  frequency  of asthmatic attacks
depends on the concentration of pollen and also on  the content
of sulfur oxides in the air. It is not influenced by pressure,
temperature, or humidity of the air.

Experiments were made to study  the effect of dust and irritat-
ing gases on infections of the  respiratory tract induced by ex-
perimentally introduced pneumococci and influenza viruses in
white  male mice. Silica dust, carbon  dust, and calcium car-
bonate dust  respectively  were  introduced into the  nostrils
together with the infectious agent. Only  the infectious agents
were applied to a control group. The dust caused extended du-
ration of disease and an increased mortality rate. Of the three
types of dust applied, silica had  the most damaging effect.  In
another set of tests, mice were exposed for 7 hrs  a day to  16
mg/cu m sulfur dioxide and 4  mg/cu m chlorine.  After 21 days
the same infectious agents were applied. Control animals were
not exposed to the irritating gases. This influence of the gases
was less pronounced in pneumococcal infections than in viral
infections, where they  produced  an intensified occurrence  of
protracted pneumonia, and increased mortality.  The effect  of
chlorine in this respect was stronger than that of  SO2.

Statistical data were compiled  in three  large cities in Poland to
study any relationship between the concentration of air pollu-
tants and the incidence of illness  or death; meteorological fac-
tors were also compared. As a  rule, highest concentrations
                         were observed to occur on calm days, whereas winds tend to
                         dissipate pollutants. The number of recorded patients during
                         favorable conditions of weather and purity of air were com-
                         pared with those who fell ill during more polluted conditions.
                         During the latter period the number of persons in Katowice
                         and Chozov  who developed diseases of the  respiratory tract
                         went up by 40%, and for cardiovascular diseases, by  13%. In
                         Krakow the  increase was 90% for patients  with  respiratory
                         complaints, and 17% for patients with cardiac. A distinct rise
                         in number of deaths in Krakow was observed on days of in-
                         creased sulfur dioxide. When SO2 exceede a  daily average of
                         0.2 mg/cu m, and the dust content at the same time was above
                         0.3 mg/cu m, the number of deaths rose by  32%  during one
                         test period. When the SO2 concentration rose  above 0.3 mg/cu
                         m, the mortality rate levelled off and no further increase was
                         observed.

                         Systematic and repeated examinations of groups of  children
                         from northern Bohemia who live in approximately equal  cli-
                         matic conditions  and  have comparable nutrition patterns,
                         revealed that  polluted air has an unfavorable  influence on  the
                         growth and the development of children. Hemoglobin values
                         drop while the globulin values in the blood  plasma rise;  en-
                         larged tonsils  were  also observed. The findings are typical for
                         air pollution of a  general type,  characterized  by significant
                         dust content  and lack of ultraviolet  radiation, but relatively
                         low concentration of sulfur dioxide. In one area, polluted with
                         arsenic,  a greatly increased arsenic content was found in  the
                         hair and nails of the children. Lack of ultraviolet radiation  ap-
                         pears to be specifically responsible for retardation in growth
                         and development, for instance, in the maturing of the bone
                         structure. An  examination of young non-smoking women living
                         in polluted areas revealed reduced vitality, faster  rate of  ex-
                         halation, pre-emphysematous condition, and in  some  cases
                         coughing with expectoration of mucus. Toxic substances  ap-
                         parently either retard or stimulate normal metabolic processes;
                         a substance in low concentration can stimulate an enzymatic
                         system, but will inhibit it in higher concentrations.

                         The subjects  sat in a closed chamber continuously circulated
                         with a mixture of air and CO.  After 8 hours  of breathing  100
                         ppm CO, a concentration of 93  ppm was measured in expirato-
                         ry alveolar air, showing that diffusion equilibrium had not yet
                         been  reached.  The  highest  concentration  of   carbox-
                         yhemoglobin  measured under these  conditions was 11.6 per-
                         cent. It  was calculated, by applying the law of mass action,

between the two over a great range of concentrations, will be
in error, since the relationship is really an exponential one. It
was shown that  exposure to  100 ppm CO  for  2 1/2  hours
caused a  significant decrease in visual perception, manual
dexterity,  and ability to leam and perform certain intellectual
tasks. The measured CO concentration is alveolar air was 55
ppm and  the COHb level was 7.2 percent.  (Author abstract

The effects of air pollution on school children in Kitakyushu
were  investigated in  November and  December, 1967  using
questionnaires about childrens  respiratory symptoms based on
the B.M.R.C. questionnaire. The  rate of  complaints  about
asthma-like  symptoms, the prevalent rate of asthma-like  dis-
eases, and the clinical findings were obtained. Also, the prac-
ticability  and reliability of the questionnaire were estimated.
The questionnaires included  asthma-like symptoms, the  length
of time lived in the  district, and also economic and social ele-
ments. The  588 children of the Shiroyama elementary school
at Yahata-ku (a highly-polluted distric with  a yearly average
dust fall for nine  years of 65.6 t/sq km/day and a sulfur triox-
ide concentration  of 1.043 mg/day/100 sq cm) and the 980 chil-
dren of the Kirigaoka elementary school at Kokura-ku (a non-
polluted district with a  dust fall of 11.47 t/sq km/day,  and  a
SO3 concentration of 0.534 mg/day/100 sq cm) were chosen as
subjects for the investigation. The pulmonary function test and
the allergen intracutaneous reaction test were carried out on
the children who  complained of asthma-like  symptoms  in the
questionnaires.  The  rates  of complaints about asthma-like
symptoms were 12.93% among children at the polluted district
and 6.46%  at  the  non-polluted district, and the  corrected
prevalence was 10.20% among  children  of the pollution district
and 5.53% among children  of the non-polluted  district. The
children of the polluted district showed a rate about twice as
high as that of  the non-polluted district in both investigations.
Thus, the questionnaire was  effective for  finding  childrens
asthma-like  diseases.  The  results  of clinical  examination
revealed that typica  and slight symptoms or atypical ones were
frequent in  asthma-like diseases of the polluted district  and
that the   tendency of  eosino-penia to  increase  was hot as
frequent. Also, the positive rate of the  allergen intracutaneous
reaction test was low in atypical asthma. These results showed
that air pollution  was closely related to the rate  of complaint
about asthma-like symptoms  and the prevealence rate of
asthma-like disease in children.

Two groups of children were  examined from Gelsenkirchen,
an area with industrial pollution, and from Westerland/Sylt,  a
control region with a clean atmosphere. In both  sexes of the
exposed children, enlargement of cervical and submandibular
lymph glands and tonsils, lower body  height, lower  values of
hemoglobin, and  depression  of  erythrocyte  resistence  was
found. The girls especially showed lower erythrocyte count
and belated bone maturation; and the boys showed lower HbE
values. The results proved  that the group diagnostic  method
can be used in other populations as well as in those for which
it was originally intended. The results are internationally com-

The  relationship between air pollution, especially sulfur diox-
ide and  bronchial asthma was investigated on  the basis of
health examinations of school children conducted since 1968 at
Fuji City, Shizuoka Prefecture. The city was divided into sec-
tions of high, medium, and low pollution according to graphs
of SO2 levels. The morbidity rate for bronchial  asthma was
2.42% in sections  of high pollution, 1.5% in sections of medi-
um pollution, and 0.88% in sections of low pollution. A similar
correlation was shown in detection rates of 5  diseases of the
upper respiratory tract. In the sections of high pollution graphs
of the monthly average of the frequencies of asthmatic attack
and levels of SO2 were  almost parallel. The rates of recovery
of asthmatic children were low in the sections where there was
high pollution, and were in general in inverse proportion to the
levels of SO2.

During the inversion  weather conditions  of December  1962,
which were accompanied by an increase in participate and sul-
fur dioxide concentrations, an increase of  the mortality in the
Ruhr Valley occurred. It was assumed that the higher mortali-
ty rate was connected with the higher air pollution. For confir-
mation of this assumption, the mortality rate outside the Ruhr
Valley was studied for  the same period of time, namely for
December 3 to 15, 1962. A significant, but a relatively lower
increase, was only found in the Duesseldorf and Cologne re-
gions. Further division according to districts did not give any
clear results. A division according to areas  of different popula-
tion  densities has shown an increase in the mortality rate in
the densely populated areas. The results indicate that the
higher death rate  was due to the  higher concentration of air
pollutants.

AIR POLLUTION TRANSLATIONS
This report is concerned with the effects of sulfur dioxide on
plants, animals, and  humans.  Sulfur  dioxide enters plants
through the stomata of leaves, damages  cellular tissue,  and
turns leaves brown and ivory. Sulfur dioxide causes tissues to
die and ciliary movement in bronchial tubes to stop in humans
and  animals. The long-term exposure of animals to  10 ppm
SO2 slows down ciliary movement. High concentrations are
very toxic, and SO2 effects the bronchi and lung more 24 hrs
after exposure than right after the exposure. There is insuffi-
cient data on the effect of long-term exposure to SO2. How-
ever, it is known that the vitamin C content in digestive or-
gans, the kidney, and the  liver decreases  and life expectancy
decreases as the concentration increases. One ppm of SO2 in-
creases the frequency of respiration and pulse; 10-20 ppm of
SO2 irritates the throat (pharynx); and 300-500 ppm of SO2
causes  toxic symptoms  even for a short-term exposure.  Re-
gional  epidemiologic studies have attempted to show quanta-.
lively that deterioration of  lung function is due to air pollution.
However, no significant difference  in lung function for re-
sidents of polluted and nonpolluted areas was found.

In K city, Fukushima Prefecture, the skeletal development of
506 boys and girls in the 5th, 6th, 8th, and 9th grades was ex-
amined by x-rays of their  right arms. A region within two km
from the aluminum refinery, polluted with fluoride (three to
five ppb fluoride and 100  to 230 kg/sq km/month fluorine per
atmospheric dust fall), and  a town  only  slightly polluted by
fluoride located six km away from the refinery were  studied.
The x-rays were classified according  to the standard of the
skeletal development determined by Greulich and Pyle. Com-
parative studies on region,  sex, and  school year were also
done. Children  in the polluted area were found a little behind
in the  development of carpal bones in the 5th and 6th grade
and  metacarpal and  digital phalanx bones in  the 6th grade.
Low levels of fluorine in the air promote the skeletal develop-
ment of 8 - 12  year old school children; however, in this stu-
dy,  such a  tendency  was not found.  Such a tendency  was
found however, in the girls in the 8th and 9th grade in the ju-
nior high school in the polluted area. Thus, if fluorine had an
influence  upon the  skeletal development,  the influence is
greater upon the smaller children, and varies according to the
individual child. There was  only a slight  difference between
the polluted area and non-polluted area. Therefore, pollution in
this  area does not have a  serious influence upon the skeletal
development of children.

Since 1950, five cities in Yamaguchi prefecture (Ube, Onoda,
Mine,  Tokuyama, and Shinnanyo)  have  applied the  Ube
                         Method to  control pollution sources based on mutual agree-
                         ment of the regional society in accordance with the scientific
                         data. In 1969, pollution was below 0.05 ppm/hr for 73.8% of
                         the total hours throughout the year at Ube, 82.5% at Onoda,
                         and 84.5%  at Tokuyama.  Although  prefecture! government
                         authorities take a serious view of the ambient air quality stan-
                         dard for sulfur dioxide, they treat the effect of pollution due
                         to fine particles lightly. According to epidemiologic investiga-
                         tions in some cities of the prefecture,  the effects of pollution
                         on the human body are apparent even when the sulfur oxide
                         levels are below  the standard. This indicates that not only the
                         single effect of SO2 gas, but also the arithmetic or geometrical
                         effects of SO2 gas and fine particles should be considered,
                         and that the establishment of an air quality standard for fine
                         particles is an urgent problem.

                         Histologjcal studies were  made of the effects of air pollution
                         on the trachea, the lung,  and the  upper respiratory tract. An
                         epidemiologic study of the effect of air pollution on the upper
                         respiratory  tract was also conducted. Either phagocytal inflam-
                         mation of the alveoli of the lung occurs, or the phagocytes ac-
                         cumulate in the pulmonary intestice, if particles remain in the
                         alveoli when dust is inhaled. Whenever dust remains in the al-
                         veoli and the bronchioli,  it brings about  proliferation  of the
                         fiber. The extent to which contaminant particles remain in the
                         lung is affected  by various factors. In the case of an aerial
                         contaminant, it varies according to the amount inhaled. Aller-
                         gic  contamination causes  typical  asthma-like   changes.
                         Pathological changes in the upper respiratory  tract due to  air
                         pollution were observed; the effect of dust increased accord-
                         ing to the order  of the pharynx, the larynx, the trachea, and
                         the lung. The effect of sulfur dioxide increased in the order of
                         the pharynx, the  trachea,  the  larynx, and  the lung. With
                         respect to objective findings observed macroscopically in the
                         epidemiological   investigation,  the  incidence  of  paranasal
                         sinusitis, laryngitis, and pharyngitis were significantly higher in
                         a polluted district than in a nonpolluted district. Also observed
                         were the parts of  the larynx and the pharynx where  lesions
                         were apt to occur  more often. Finally, the movement  of gar-
                         gling  water was observed by  roentgeno-cinematography  to
                         determine whether gargling water could make the surface of
                         the mucosa clean and which part of  the pharyngeal cavity it
                         reached.

                         representative contaminant in Japan today. As  a result of long-
                         term exposure to SO2 at the present  atmospheric concentra-
                         tion; an increase of inflammation,  mainly bronchitis, has  been
                         reported by epidemiological and experimental research. Inhibi-
                         tion of ciliar movement of the epithelium cells in the bronchial
                         wall is indicated as a reason for this increase. Also, the SO2
                         has a  high degree of deposition  and retention in  the lungs.

There  are not many  areas  where  nitrogen dioxide is the
overwhelming contamination factor, its epidemiological effects
are not  clear.  From  long-term  exposure experiments using
minute amounts of NO2, it was  concluded that this pollutant
may cause obstructive lung disease in the same way SO2 does.
The influence  of  carbon monoxide is completely different
from that of SO2 and NO2. Carbon monoxide has a strong af-
finity for the hemoglobin in the blood. Once CO has combined
with hemoglobin,  it is  very difficult to release;  it inhibits the
action  of Hb,  thereby causing  cerebral disorders.  Carbox-
yhemoglobin  is  also harmful to the patient with ischemic heart
disease. The  environmental  standard of CO should be made
taking these factors into consideration.

(Taikiosen to kokyukishikkan). Text in Japanese. Sanfujinka

Historical examples of air pollution damage, various respirato-
ry diseases influenced by air pollution, and the relationships
between  constitution and air pollution are described. Bronchial
asthma,  chronic   bronchitis, vesicular  emphysema,  pneu-
moconiosis,  and  lung  cancer are increasing in  Japan  and
abroad. Among these  diseases, bronchial asthma and  chronic
bronchitis are easily influenced by air  pollution; the rise and
fall of these symptoms are related to sulfur dioxide concentra-
tion and  to dust fall. Chronic bronchitis has a connection with
smoking,  like vesicular emphysema and pulmonary  fibrosis.
The incidence of pneumoconiosis and lung cancer is higher in
those who have many ooportunities for inspiring dust than it is
in others. Allergies are also  easily  influenced by air pollution.
In animal experiments if  an antigen is  inspired after the in-
spiration of air  pollutants, sensitization via the airways is easi-
ly established. Though it is noted that alpha 1 - antitrypsin in
the blood may take part in the crisis of vesicular emphyseam,
the relationship between its quantity and the basic factor easi-
ly influenced by air pollution  has not been clarified.

The organs  of  rats injected with  a radioactive lead  isotope
were studied by  hystoautoradiographic techniques to deter-
mine cellular localization of  the lead. Organ sections prepared
on  demonstration slides were spread with photographic fluid
using the stripping method. After 30-45 days in which the fluid
was exposed  to the radiation emitted from the hystologic cross
sections,  the slides were developed and colored, and later
washed. Results confirmed the findings of other investigators
that lead diffuses rapidly in several organs, principally, in
order of preference, in the liver, lungs, kidneys, and spleen. In
the first  few  hours  after  injection  the  deposits  of  the
radioisotope are massive. Several of the hystoautoradiographs
of the liver suggest a  deposition  of the metal both inside and
outside the cell.

INVESTIGATION ON THE INFLUENCE OF  SMOKE  AND

The influence of atmospheric pollution on school children was
investigated. An elementary school in Osaka City was selected
to represent a polluted area and an elementary school in Ikeda
City was selected as the control school. A total of 528 children
of the fourth and sixth grades from both schools were the sub-
jects of the investigation. To have medical and otorhinolaryn-
gological examinations three times a year, and to examine the
relationship between the daily change of pollution and that of
respiratory functions, investigations were made for five suc-
cessive days. The amount of floating dust and sulfur dioxide in
the air  was measured since the day before the examination
began. Three days  prior to the examination,  questionnaires
were distributed and absences were  noted. The parents of the
children in the polluted area were mostly blue-collar workers,
and those of the children in the contrasting school were mostly
white-collar workers.  A  high  rate  of  conjunctivitis and
trachoma  was observed among the children in the  polluted
area. No difference was found in absences. A high rate of sore
throats, headache, and coughs was  observed among the chil-
dren in the polluted area. Concerning height and weight, the
children in the  polluted area were inferior, but  no  difference
was found  in growth rate. The examination  of respiratory
function,  by means of a  Vitalor, indicated no significant dif-
ference between groups of the  same height. The examination
of  vital capacity  showed no difference  for one second; but
children in the  polluted area had lower capacity for 0.75 and
0.5 sec. The children of the polluted  area showed an obviously
lower rate of breathing capacity. The value of respiratory re-
sistance  showed  a  noticeable   difference between  the  same
grade children. The  over-all five-day examination, however,
showed no distinctive difference between the two groups.

Ako residents over 40 years of age were surveyed concerning
coughing, phlegm,  dyspnea,  and smoking, according to the
BMRC method. Based on the results, those residents with sub-
jective symptoms were more closely examined. The morbidity
for chronic  bronchitis (Fletcher s definition) increased with in-
creasing rate of  smoking and increasing age. Comparison of
bronchitis morbidity for different areas,  having sulfur dioxide
values of above  or below 0.2 mg/day/100 sq cm by the lead
peroxide  method, did not show  any significant differences,
although  morbidity was high in the area having  the value
above the boundary  value. Obstructive ailments were  most
frequent  among  the  chronic bronchitis  groups,  followed by
those  suffering from other illnesses. For  all cases, the frequen-
cy of  obstructive ailments was related to smoking rate and in-
creased age. With an increase of over one mg/day/100 sq cm
of SO2 values, the morbidity for chronic bronchitis increases
in Ako.

VITAMIN  E.    (Luftfororeningar — skyddande verkan  av
vitamine  E).  Text  in  Swedish.   Svensk  Farm.  Tidskr.,

Human activities account for only 0.05% of the total pollution
in the atmosphere, but the concentration of these substances
around large population centers poses a serious problem. The
problems of photochemical smog, ozone, the  nitrogen oxides,
and certain hydrocarbons are reviewed.  Experiments with rats
deprived  of Vitamin  E in their diets  indicates that these are
considerably more susceptible to lung  damage  from a high
concentration of  ozone in the atmosphere than are control rats
fed with a diet  rich in Vitamin  E. The apparent protective
mechanism  involved is the  fact that  nitrogen  dioxide  and
ozone tend to destroy the Vitamin A in  the body, which is
vital to the normal functioning of lung tissues. The Vitamin E
                        protects  Vitamin  A  from destruction by  NO2 or O3. The
                        mechanism by which Vitamin E exerts  its protective  action
                        against the influences of NO2 and ozone  was studied. Prelimi-
                        nary results indicate that the main product of the oxidation of
                        alpha-tocopherol (Vitamin E) is an open-ringed monomer with
                        benzoquinone structure. This tocopherylquinone is one  of the
                        normal decomposition products of Vitamin E to be found in
                        the human body.  Thus Vitamin E would seem to protect the
                        body from these strong oxidizing gases by reacting with them
                        to form harmless metabolites.

                        The case of beryllium granuloma on the right ring finger of a
                        young man was reported. The granuloma results from a cut by
                        a  glass fragment  from a fluorescent lamp. Patch tests with
                        beryllium sulfate  (2%) and with beryllium nitrate (0.38, 0.19,
                        0.019, and 0.0019%) were positive. Regression of the swelling
                        was at first observed with almost 2000 mg of prednisone. The
                        condition  became worse immediately after  medication was
                        stopped.  The granuloma was removed surgically. Five years
                        later the patch test was still positive. The clinical and func-
                        tional results of the operation were very  good. Repeated tests
                        on a patient with beryllium salt solutions in order to follow the
                        course of the disease may cause sensitzation. Excitation of the
                        granuloma over  corticosteroid  therapy  was recommended.

                        The toxicity of sodium salts of o-(methylseleno) benzoic acid
                        and o-(methyltelluro) benzoic acid was studied by  determining
                        death percentages amomg mice over 24 hr as  a  function of
                        various dosages of the sodium salts. Each dosage  was studied
                        for 20 male and 20 female mice. O-(methylseleno) benzoic acid
                        was less  toxic  than o-(methyltelluro) benzoic acid, but quicker
                        to act At the 40% lethal (DL 40) dosage, death occurred  one
                        hour after injection; at DL 70 and DL 100, it occurred in  less
                        than 30 min. With the sodium salt of o-(methyltelluro) benzoic
                        acid, death occurred only 12-24 hr after injection. Males  and
                        females showed no significant difference in susceptibility to
                        the two substances. The mice did not exhibit a toxic reaction
                        to the salts, and no specific cellular lesions 'due  to toxicity
                        were observed.

A study was  undertaken to determine whether and what kind
of  influence  cadmium  compounds have  on dentition, the
periodontium, oral mucosa,  and bone structure of the man-
dibular shaft  among workers involved in the production of al-
kaline storage batteries. The majority of those studied suffered
from oral dry ness, while a significant number experienced a
metallic taste. The dentition of the subjects was generally bad,
and a comparatively large number of teeth had been removed.
A yellow hyperchromatism of the teeth was observed in 41 of
the 80 subjects, with a distinct relationship between the inten-
sity of the hyperchromatism  and exposure time. The condition
of the periodontium was also unsatisfactory, but the condition
of the oral mucosa did not deviate from the norm.

With the aid  of a case report,  the fatal course  of boric  acid
poisoning is described in terms  of its clinical and biochemical
picture.  The  extremely widespread  pediatric application of
boric acid in  solutions, salves, and powders, and the oral ad-
ministration of boric acid for the treatment of thrush, lead one
to expect significantly higher frequencies of boric acid poison-
ing than appear in the published literature. Bloody vomiting,
diarrhea, convulsions, coma, oliguria, and  anuria characterize
boric acid poisoning,  along with  exanthema which is always in-
tensely  red.  Diagnostic  methods  to  be  used  in cases of
suspected poisoning are mentioned.

The retention and distribution of mercury were studied in ex-
periments with mice  during  a four week period  following the
intravenous administration of mercuric  chloride (Hg~230) and
the subcutaneous  application of sodium selenite, sodium tellu-
rite, and sodium sulfite. Both sodium selenite and sodium tel-
lurite caused  a long term retention of mecury in the organism
and altered the distribution of mercury in the organs. Sodium
sulfite did not influence  mercury retention, and caused only
insignificant changes  in the distribution of mercury. The effect
of these compounds depended upon the redox potentials. Sodi-
um selenite and sodium tellurite are reduced in the organism,
and form compounds of a colloidal nature with mercury which
are retained in the organism.  (Author summary)

PRODUCTS OF SMOLDERING PLASTICS. Arch. Hyg. Bak-

The increasing use of plastics raises the question of whether
their thermal  disintegration products,  in case of  a fire, would
produce poisonous or irritant effects. A test installation for the
smoldering  of various plastics  is  described,  which allowed
animal experiments of the toxicity of the smoldering products.
In wood smoldering, the predominate toxicological risk is from
carbon monoxide, as was shown by carboxyhemoglobin deter-
minations in rats. The toxic smoldering products of a polyester
material, which have a strong irritant effect on the lungs, must
still be chemically identified. (Author summary modified)

Death  records for 70,000 residents  of Tokuyama  City were
analyzed to determine death rates for two categories of dis-
eases:   endogeneous,   constitutional   diseases   (cerebral
hemorrhage, cancer, and heart disease) and ectogeneous,  in-
fectious diseases (pneumonia  and bronchitis). Further,  the
death rate for each category was compared with national death
rates for the periods 1958-1969 and 1962-1965.  The relationship
between death rates and quality of soil, water, and air was
considered. In Tokuyama City  and throughout Japan, deaths
attributable to ectogeneous, infectious diseases are declining
while those due to endogenous, constitutional diseases are  in-
creasing. The  tendency is especially noticeable in Tokuyama
City. In all years, decrease in air pollution was associated with
decreased mortality from pneumonia and bronchitis  in two
sensitive groups: infants and children up to four years of age
and adults  over 40 years. With respect to their influence  on
death rates, dust fall and sulfur dioxide are in direct propor-
tion to each other.

The relationship between air pollution and chronic obstructive
respiratory disturbances was examined according to  sex and
age in three-year olds (15,000),  six to 11 year  olds (27,000),
and adults over 40 (15,000) in five cities of Yamaguchi Prefec-
ture: Ube, Onoda, Mine, Tokuyama, and Nanyo. The mortali-
ty rate for bronchitis decreased sharply as dust pollution was
replaced by gas pollution. Less of a decrease was observed for
mortality from asthma. The mortality rate of asthma relative to
that of bronchitis is increasing yearly. A positive correlation
was observed between the air-pollution level (volume of dust
fall and sulfur  dioxide concentration), medical  histories and in-
cidence of  obstructive respiratory diseases according to city,
district, age and sex, in subjects over 40.

Studies show a correlation between the occurrence of diseases
of the respiratory tract and the degree of air pollution. Pollu-
tants  exert  their effect  on the respiratory  passages either
directly on the mucous membrane or indirectly by way of vari-
ous nervous centers or various physiological functions such as
breathing frequency or breathing resistance. Damaging gaseous
pollutants are sulfur oxides, nitrogen oxides, oxidizing agents,
and aldehydes. The data on the effects of sulfur dioxide that
can serve as a basis for recommending a medical norm derive
from  both experimental and epidemiological  studies. Experi-
mental studies relate to  such fundamental questions as  the
mechanisms  and  relative  toxicity  of  various  substances.
Epidemiological studies show that in the London disaster of
19S2, a marked  increase  in  mortality  was  observed after
several days of a daily average sulfur dioxide  level content of
75 ppm with local 48-hour values as high as 134 ppm. A two-
hour SO2 value not to exceed 25 ppm and a 30-day value not
to exceed 5 ppm is recommended.

Autopsy findings are reported for carbon monoxide poisoning
due  to imperfect combustion of household gas  or charcoal.
The  cases examined included nine of nonintermittent poison-
ing,  four of incompletely intermittent poisoning, and five of
completely intermittent poisoning. Pathological changes involv-
ing demyelination of the  cerebral  white substance (substantia
alba) were common to all cases. In four of the nonintermittent
cases and three of the completely  intermittent  cases, there
were  also  obvious changes  in the globus pallidus, one of the
important centers of the extrapyramidal motor system. Among
the completely intermittent cases, only one showed changes in
the globus pallidus. Changes in the cerebral cortex were entire-
ly absent in the incompletely intermittent cases, although they
were present in two nonintermittent cases and  one incomplete-
ly intermittent case. While not as  pronounced as those of the
substantia alba, changes in the globus pallidus are  more close-
ly related  to  the essential processes  of  carbon monoxide
poisoning than changes in the cerebral cortex. This is because
the frequency of the incidence of changes  in the globus pal-
lidus  occupies a position midway between that of the changes
in the cerebral white substance and  those in the cerebral cor-
tex.

REPORT ON THE INVESTIGATION INTO THE EFFECT BY
SMOKE AND SO ON.  (Bien  to eikyochosa hokokusho). Text
in Japanese. 107p., 1968 (?)•
Air pollution was investigated with respect to  its effect on the
health of school children. Pollutants were tested for traces of
sulfur dioxide, sulfuric  acid ion and  mist, nitric acid ion, vari-
ous  metals  (titanium,  vanadium,  manganese,  iron,  nickel,
chromium,  and lead), nitrogen oxides, hydrogen sulfide,  al-
                         dehydes,  aerosols, and particulates. Elementary  school chil-
                         dren in two polluted areas and two non-polluted areas were
                         examined for respiratory  function. Health investigation cards
                         were distributed prior to  the  examinations. Chest X-ray and
                         otorhinologjcal examinations were given annually.  Based on
                         the  medical histories,  the  rates of asthma and pneumonia in
                         the  children in polluted school districts were 7.5 and 2.4 times
                         higher than those in nonpolluted districts. The rates for con-
                         junctivitis and trachoma were  also high and differed  signifi-
                         cantly for the polluted and nonpolluted districts. Complaints
                         about sickness, sputum, eye, ache, and pharyngeal ache were
                         3.7-6.7 times more frequent for the polluted districts; the rate
                         of absenteeism due to respiratory diseases was  also  higher.
                         The respiratory function of children in the polluted school dis-
                         tricts decreased 87% (56.3% was significant); respiratory tract
                         resistance increased  47% on the  average  and  there  was
                         blocking damage. The tendency increased annually. The rate
                         of specific inflammatory findings in  the pharyngeal parts was
                         high for the polluted districts  and also increased yearly. Data
                         on  meteorology,  environment,  and other medical inquiries

                         the  respective districts according to the following  sulfur triox-
                         ide  levels (in mg/day/100 cm PbO2): below 0.3, 0.3-0.5, 0.5-1.0,
                         1.0-1.5, and above 1.5.  There was no correlation between  the
                         SO3 level distribution  and sensitivity to colds.  Complaints of
                         eye trouble and sore throats increased with an increase  in SO3
                         level. Males in thy 0.3-05 district and  females in the 0.5-1.0 dis-
                         trict had  greater frequencies of  sore throats. Significant dif-

                         in the 1.0-1.5  district. Asthma, eczema, and urticaria were also
                         discussed.

                         slight or middle interstitial inflammation.  The  guinea  pigs
                         developed symptoms  of  hemorrhagic bronchopneumonia. A
                         group of  guinea pigs inhaled silica particles prior  to treatment
                         with bacteria and exposure to  SO2. The number of silica parti-
                         cles and  their residue due to SO2 exposure increased in  the
                         wall of the alveorus pulmonis.  Germ free animals were ef-
                         fected more than conventional animals, indicating an adaptive
                         response.

A STUDY OF THE  DISTRIBUTION  IN THE  ORGANISM
AND  THE RATE OF ELIMINATION OF THREE  BORON

Distribution in the  organism and  the rate of elimination of
boric  acid, potassium  borotartrate, and 5-methyl 5-n-propyl 2-
p-tolyl 1,3,2,  dioxaborinane (MPTDB) were  investigated. In
acute  or subacute poisoning in the rat, boron is very diffusible
for all three compounds. While this diffusibility is  also ob-
served in short and long-term poisoning, localization in certain
organs also occurs.  Among the organs which retain the most
boron  are  the liver,  the  kidney, the brain, and the adrenals.
The localization in the kidney is  of interest because of the im-
pairment of renal function that  occurs in acute or subacute
poisoning by these compounds. Adrenal localization also is of
interest  since  boric  acid  tends  to form  complexes  with
polyhydroxyl compounds which  gives it the ability to  inhibit
the oxidation of adrenalin. Boron  was  found to  cross the
placental barrier, which  explains the considerably diminished
vitality of the offspring from mothers subjected to repeated in-
gested doses of boric acid. While the elimination of MPTDB is
clearly much slower when administered in repeated doses, a
considerable portion of the boron for the  three compounds is
rapidly eliminated in the urine.

AIR POLLUTION AND CHRONIC BRONCHITIS. (Taiki osen

A questionnaire survey based on the BMRC method was  con-
ducted among residents of Osaka to determine the relationship
between  air pollution and chronic bronchitis as defined by
Fletcher. For the survey, 829  persons over 40 years old were
chosen at  random.  The  morbidity for chronic bronchitis for
each area, computed from the survey data, was corrected for
age-group  differences and cigarette smoking. The  corrected
morbidity for each area  correlated with the concentration of
sulfur dioxide measured  in the area. For  those patients  with
chronic bronchitis including asthma, the frequency of the daily
increase in severity of the illness was correlated with the  con-
centration of sulfur dioxide for each day. The rate of increase
of severity increased rapidly over the maximum daily concen-
tration of 0.3 ppm.  The  chronic  bronchitis patients  were
further examined by the Vitalor method, and the frequency of
obstructive difficulties based on the one-second rate tended to
become higher with age and smoking.

The effect of  air pollution in Osaka  on human health was in-
vestigated with respect to rates of absence  for school children,
mortality  rate, and  examinations of peak  flow value  and
forced vital capacity.  Sulfur dioxide and dust concentrations
were determined. No correlation was determined between data
on absenteeism at schools in industrial, commercial, and re-
sidential districts and the degree of pollution  in the districts.
The fluctuation of the number of absentees due to respiratory
diseases (cough, bronchitis, pneumonia, asthma)  corresponded
with that of total absentees, but was not correlated with sulfur
dioxide concentrations.  The mortality  rate,  modified  with
respect to age, was calculated and compared for each district.
Mortality decreased annually. A higher than average rV4te was
determined at a seaside industrial district and  infant mortality
and deaths due to pneumonia and bronchitis were frequent.

Certain areas in Yokkaichi City  were designated as polluted
areas with high concentrations of sulfur  dioxide which in-
creased annually.  Obstetric  and gynecological  studies  were
made  with  respect  to  respiratory  diseases  (colds  and
bronchitis) during pregnancy, nausea, late  gestational toxico-
sis, determination of erythrocytes and hemoglobin, amount  of
hemmorrhage at delivery, frequency of obstetrical operations,
rate of premature deliveries, placenta weight,  and rate of still
births.  The new born children were examined  to determine
body weight, asphyxia, jaundice, abnormal body temperature,
mortality, and malformation. The results differentiated signifi-
cantly  between cases from the polluted area and the non-pol-
luted area. Respiratory infections  during pregnancy, serious
jaundice  of the new born child,  premature  births,  and still
births  had a high and significant incidence hi  the cases from
polluted areas.  Of high incidence but not statistically signifi-
cant in the polluted area cases were anemia during pregnancy,
premature  deliveries, pyrexia and asphyxia of the new born
child, malformations, and an  increase in placenta weight.

(Taikiosen ni yoru kokyuseishikkan no kanrihoshiki ni kansuru

The effects of air pollution on human health were determined
epidemiologically in Yokkaichi City. Common cold, bronchial
asthma, pharyngitis, preocular diseases, and death due to ob-
structive respiratory diseases increased. The increase in occur-
rences  of pharyngitis,  characterized  by paleness  of the
pharynx posterior wall, lymphatic nodules, redness, swelling,
and  fragmentary  cut of  the  epidermal blood vessel,  and
respiratory diseases with asthmatic attack was  correlated  to
sulfur dioxide concentration.  Based on lexicological animal ex-
periments  on exposure to SO2,  congestion of  the lung and
hypertrophy of the muscular layer supporting the bronchial
wall were  determined along with abcess formation in the lungs
of dead animals. Clinical findings for patients with obstructive
respiratory diseases confirmed the overwhelming  prevalence
of bronchial asthma symptoms greatly correlated with air pol-
lution.  Based  on statistical  data  of residence  classified  by
months, the incidence  of obstructive respiratory diseases  in
the Shiohama region was  5.89%, increasing to  10.38% in May.
The incidence was greater for women than men  and for those
over 50 and under ten years old.

The  effect  of  cigarette smoking  on  the  electroretinogram
(ERG)  and the electro-oculogram  (EOG)  is  discussed.  A
cigarette  with 1 g of tobacco usually contains 10 to 20 mg  of
nicotine and 0.3 to 3%  volume of carbon monoxide, among
other substances.  In a cigarette with 1.5% nicotine, approxi-
mately  5 to 7.5 mg end up in the mouth. Approximately 60% is
resorbed by the organism in the case of leisurely smokers, and
up to  90%  by  persons  who inhale deeply. The effects  of
nicotine on the nervous system, the peripheric circulation, the
hormones which influence  the blood  pressure, intra-occular
circulation, metabolism in the  retina, and CO  saturation are
examined. Control experiments were performed  on 18 non-
smokers and seven occasional smokers, all with perfect vision.
Two unfiltered cigarettes were  smoked  as quickly as possible
and inhaled. Tests  were  then made and pulse and respiration
rate were measured. The  average EOG  curves showed that
resting  potential was 958 microvolts before  smoking and 817
microvolts after two cigarettes. A rise in blood pressure was
noted in  86% of the occasional smokers;  72% showed no
change in pulse  rate. Results of additional tests are included.

A study of ten patients (five in the seriously ill  group and five
in  the  medium group),  who were  among the acute carbon
monoxide poisoning casualties  that resulted  from a coal dust
explosion, was  made approximately 11  months after the dis-
aster. Polygraphic records were made of their brain waves dur-
ing  natural sleep throughout an entire night. A total of four
subjects,  three  in the serious group and one in the medium
group,  experienced sleep disturbances. The ratio of light sleep
phase and the paradoxical sleep phase  to the total  sleep was
high compared to normal individuals; the ratio of medium and
deep sleep was low. The ratio of the deep sleep phase was
lower in the serious group than in the medium group, while the
paradoxical sleep phase ratio was higher. The sustained length
of the paradoxical sleep  phase was longer than that in normal
adults;  this tendency was more marked in the  serious group.
The cycling of the paradoxical sleep  phase overall was not
particularly anomalous. The amplitude of the rounded waves
and spindle waves was generally low, as was the frequency  of
their appearance,  which was  more marked  in  the serious
group.  The  trend  in pulse rate  and  body  movements was
similar to that of normal  adults. (Author summary modified)

                         One gram of beryllium oxide (a carcinogen) in the form of a
                         suspension in a physiological solution was given intravenously
                         to  20 rabbits.  The  animals were observed together for 18
                         months from the beginning of the infection. In rabbits that sur-
                         vived for more than 15 months, bone tumors were observed in
                         three cases. Histologically, all tumors were  classified  as sar-
                         coma osteogenes.  The tumors  were highly  malignant of the
                         osteogenic sarcoma  type, bringing metastases  to  the lungs.
                         Histologically, they  are  distinguished  by their  considerable
                         heterogeneity. A constant feature of all tumors obtained in a
                         pronounced tendency of their cells to become differentiated in
                         the  direction  of  atypical osteoblasts.  It appeared that the
                         degree  of osteogenesis occurs in tandem with the degree of
                         malignancy. Independently of the marked inhibition of the ac-
                         tivity of basic phosphatase in  parenchymatous organs, the
                         bone tumors  observed  indicated a high  activity  of basic
                         phosphatase. Tumors developed histogenetically are connected
                         with  new connective tissue elements of the marrow which
                         have the capability of becoming differentiated into osteoblasts.

                         The reactions of the  respiratory tract to exogenous stimuli
                         were examined. The response of the respiratory tract and
                         lungs to inhaled particles was mainly  dependent on the area of
                         deposition and retention. The effect  of the stimuli was deter-
                         mined greatly by particle size and number.  Inhaled  particles
                         and gases may interact; the effect of sulfur dioxide would be
                         largely  determined  by the  presence of other aerosols. The
                         evoked response could be as nondirect as a sequela of resorp-
                         tion in the nasopharynx. Sequential exposure and smoking had
                         a deteriorating influence on adequate  physiological reactions.

                         presented; a graphic analysis of lead  content in urine  and lead
                         absorption through the digestive tract, all classified according
                         to various age groups is given. The amount of lead obtained by
                         subtracting lead content via digestive system from the total
                         lead content in urine may be assumed to be the amount which
                         has been  inhaled from the  air without causing deposition of
                         lead (lead surplus). Assuming that 50% of the lead  quantity
                         from the inhaled air was absorbed, a reverse calculation can
                         be made in order to estimate the lead concentration in the  air
                         that does not cause deposition in the human  body. Assuming
                         the average air intake of the adult Japanese per day is 10 m3
                         and that of a child is 5 m3, cumulative air intake of each age
                         group  was used to divide the lead surplus and multiplied  by
                         two. According to this calculation, 1.5 to 4.4 micrograms/m3 is
                         the amount of lead concentration in the air that does not cause;
                         lead deposition in the human body of adult Japanese  between
                         the ages of 40 and 50.

The minimum sulfur dioxide and phenol concentrations sensed
by olfactory organs  when only one of them was present in the
atmosphere were .87 mg/cu m and .022 mg/cu m, respectfully
and .33 mg/cu m SO2 and .011  mg/cu m phenol when both
were present simultaneously. The minimum concentration ef-
fecting light sensitivity of an eye and electric activity of brain
was .44 and  .011  mg/cu m SO2 and phenol, respectively. Com-
bined effects of SO2 and phenol are close to sum of their in-
dividual effects. Thus when both SO2 and phenol are present
in the  atmosphere,  their maximum instant concentration ex-
pressed as sum of fractions of maximum  permissible concen-
trations of isolated  substances,  should be less than one. The
resorplive effect of low concentrations  of SO2 in the presence
of phenol on white  rats was studied by three months of con-
tinuous  intoxication by inhalation. The atmosphere containing
l.Smg/cu m SO2  and .5 mg/cu phenol and .5 mg/cu m SO2 and
.05 mg/cu m phenol caused considerable  pathomorphological
changes in white rats organism. Hence, when SO2 and phenol
are present simultaneously  in the air, the  maximum permissi-
ble average  daily concentration of SO2 and phenol expressed
in fractions of the average daily maximum permissible concen-
trations of isolated substances is recommended to be less than
one.

Systems, McGregor and Werner, Washington, D. C., lip.
The effect of chronic lead poisoning on reproductive capacity
was  reviewed. Cases of infant  mortalities and miscarriages
were presented. In one example, two cases of miscarriages in
the wives of house painters were reported. The women first
gave birth to healthy children  before  the  husband became a
painter, and a second gave  birth to healthy children when the
husband ceased being a painter. Both had signs of lead poison-
ing. A case was reported in 1896 where a woman married to a
painter gave birth to two healthy children in the first two years
of his being a painter; simultaneously  with his  showing  signs
of lead  poisoning, she started a  series of 15 miscarriages. In
1901,  a woman married to  a painter had  22 pregnancies, six
ending with miscarriages, six with premature birth,  and five
children died in infancy. She had no history of lead poisoning.
In 1906, the  normal infant mortality rate in Lille  was 8.2%, but
among children of painters, 22.9%. It  was apparent that the
fathers  working  with lead  may  have  a limited influence as
compared with the mothers doing so. Individual animals tests
performed in 1914 on rabbits and  chickens showed  that the
progeny of a lead-poisoned male and a normal female were in-
ferior to normal  progeny. Of 13 married female lead workers
in a printing shop in 1896, having 56 pregnancies, there  were
26 miscarriages, nine premature births,  one stillbirth, 21 living
births at term, and 17 dead shortly after. Other studies show-
ing similar results are reported.

The effects of metallic quicksilver, an inorganic mercury salt,
and the alkyl mercury  compounds are compared. In 1953,
cases of a mysterious nervous disease began to appear among
the population of the city of Minamata, Japan. The suspicion
that it could be alkyl mercury poisoning was confirmed when
the patients were found to be excreting mercury in  their urine
for the first five months after becoming ill. Further investiga-
tion revealed that a chemical plant which used mercury com-
pounds as catalysts had released waste products into the Mina-
mata Bay, and several types of fish subsequently were found
to have a high mercury content. Feeding  experiments were
conducted with six month old white leghorn hens which were
given 12.5, 25, and 50%  Panogen treated grain. In the groups
whose  feed contained 25 and 50% Panogen, both  food  con-
sumption  and  egg production decreased. Alkyl mercury
poisoning in wild pheasants is also discussed.

lead content in the  blood of the two population groups was 29
gamma %  and 37 gamma %, respectively. In ten especially ex-
posed policemen, 38 gamma % lead was in the blood, however
this group was  not tested 10 years ago. The levels in office

the atmosphere  can therefore lead to acute impairment of
health, as proven by increased mortality during smog episodes
(1952, 1962). Measurements have shown that fine particulates
increased in concentration in the Ruhr region the 1965-1969
period. A comparison of two groups of children, one living in
the polluted atmosphere of Gelsenkirchen and the other in the
unpolluted  atmosphere  of Westerland/Sylt, showed retarded
bone  maturation,   especially  in  the  Gelsenkirchen  girls.
Whether this is  attributable to  the tenfold concentration of
SO2  and H2SO4 in Gelsenkirchen or to the climate has not
been determined. In another  study, persons exposed to low
concentrations of dichloromethane manifested a considerably
reduced ability to concentrate compared with a control group.
Some noxious substances like derivatives of ethyleneimines
cause genetic damage by increasing the  spontaneous rate of
mutation, considerably exceeding such  damage  caused by
radiation. Such  substances causes chromosomal  damage at
concentrations far below their toxic threshold concentrations.

The correlation between  a  sudden increase in sulfur dioxide
concentration due to an accident in a chemical factory in Ube
City  and the increase in symptoms of discomfort, respiratory
diseases, and deaths was  investigated. Concentrations of SO2
and dust particles, temperature, humidity, and wind direction
and velocity were  determined and plotted for monthly varia-
tions. Epidemiologic studies  determined  a  definite  parallel
between the rise in SO2  concentration and  dust and the in-
crease  in number  of  patients.  Most patients suffered  from
quasi-influenza  of the upper respiratory  tract,  which  con-
stituted  95% of  the cases of respiratory illnesses among ba-
bies. Cases of bronchitis  decreased and bronchial asthma and
pneumonia  increased among the  aged. Death rates rose from
3% in June to 14.1% in July-August, with a marked increase
on the days following the rise in SO2 concentration. Daily ex-
aminations determined a definite reaction (higher temperatures
and pulse rates) of chronic respiratory and lung tuberculosis
patients to air pollution.

THE EFFECTS OF SOLID, LIQUID, AND GASEOUS POLLU-
TANTS  ON THE LUNGS.  (Die Lunge  als Aufnahmeorgan

German. Praxis Pneumol., 25(9):505-518, Sept. 1971. 19 refs.
Regulations stipulating maximal  permissible concentrations of
solid, liquid, and gaseous pollutants must take into considera-
tion whether the pollutants are deposited in the lung, absorbed
into the blood stream or cause direct damage to the pulmonary
system.   Animal  experiments and electron  microscopic  ex-
amination of the submicroscopic  structure of pulmonary tis-
sues  are described designed to  determine the parameters in-
fluencing pulmonary resorption. Epithelial-alveolar cells are of
crucial importance in these studies. In one experiment,  the
pulmonary resorption of a fine oil aerosol, designed to  simu-
late the behavior of particles soluble in  benzene, was deter-
mined  by determining silicon dioxide in  the lung and  the
mediastinal lymphatic nodes  16  hours, five days, and  four
weeks following inhalation. Pulmonary resorption was a very
complex phenomenon which depends on the penetration power
of the particles, their deposition in alveoli their bronchial and
                        lymphatic elimination, particle solubility, and their cytotoxici-
                        ty. About 95-98% of the sulfur dioxide is retained by the al-
                        kaline mucus of the upper respiratory tract; it penetrates  into
                        the lung only when adsorbed on the surface of dust particles
                        or when it is catalytically converted to a  sulfate-ion aerosol.
                        Non-reactive gases and vapors penetrate the lung by diffusion
                        with the resorption degree proportional to the gas concentra-
                        tion and duration of exposure. Carbon monoxide is also men-
                        tioned.

                        and degree of sulfur dioxide pollution was  studied in a sample
                        comprising 3547 men and women. The acute respiratory mor-
                        bidity  rate was significantly  higher not only on  the days with
                        increased levels of SO2 concentration, but also during the  two
                        days  following the exposure. A relationship  was  not found
                        between morbidity rate and  outdoor temperatures. High con-
                        centrations  of  SO2 were recorded  during November  and
                        December, which were in agreement with high morbidity rates.

                        Fifteen rats were  reared since September, 1969 at the Isozu
                        district in Yokkaichi City where air pollution was most severe.
                        Ten rats reared at the University in Tsu were used as controls.
                        The rats were raised outside and were killed after six months,
                        one year, and a year and half. Average concentrations of  pol-
                        lutants in Isozu were: 0.140 mg/day/100  sq cm nitrogen  and
                        1.269 mg/day/100 sq cm. sulfur dioxide. According to histologi-
                        cal  findings,   lung  congestion,  neutrocytes   around  the
                        bronchus,  infiltration  of lymphocyte,  and  emphysemtous
                        changes were  observed among the  rats  raised six months in
                        Isozu. Among  the rats reared one year in Isozu, emphyse-
                        matous change  on the lungs was obvious, and infiltration of in-
                        flammatory cells in the interstice was observed.  Among the
                        rats reared a year and a half in Isozu, pulmonary emphysema
                        and cell infiltration of interstice were observed.  Among the
                        rats reared one year and a half in Tsu, no significant: changes
                        were observed  except for lung congestion, slight cell  infiltra-

                        month  exposure  between September and February  caused
                        bronchitis and  a  year and a half exposure causes pulmonary

Sensitization  of guinea pigs with nucleoproteins derived  from
the lungs of rats  with experimental  berylliosis  specifically in-
creases the intensity of the intradermal  Curtis test with  2.5-3
micrograms of beryllium chloride, induced through allergy to
the complex  of beryllium plus auto-protein. The greatest ac-
tivating effect is produced by a combination of delayed hyper-
sensitivity to  both antigens. This suggests that the Curtis test
in berylliosis patients is related not only to the sensitization by
the beryllium plus protein complex, but also to the influence
of auto-allergic processes. (Author summary modified)

TORY SYSTEM.   (Poluicao  atmosferica:  acao  sobre o

28(6):247-251. June 1971.
The impact of air pollution  upon the population and measures
to be taken in  fighting  air  pollution are discussed. Industrial
emission  sources, automotive vehicles, and open air burning of
refuse are  the  main  contributing factors  to  air pollution in
Brasil. No scientific proof  defining specific diseases induced
by air pollution had been found so far. However, air pollution
may worsen pre-existing conditions in patients with bronchitis,
asthma, emphysema or cardiopulmonary  conditions which con-
stitute the  major part  of  victims  due  to  pollution.  Graphs
representing the parallelism between smoke and sulfur dioxide
concentrations in the air and the exacerbation of pulmonary
disease  in  groups  of  patients  held  under  control  are
reproduced. A program of preventive measures including  early
diagnosis  and  treatment of pulmonary disease should be
developed.  Complex teams including clinical physicians, lung
specialists, allergists,  and  specialists  in  nuclear  medicine
should  be   established  to  prevent  air  pollution-induced
episodes. Technical measures should be taken to prevent in-
dustrial, automotive, and other burning emissions.

Germ free guinea pigs were used for an experiment to study
the effect of sulfur dioxide on the upper respiratory tract,
especially paranasal  sinuses. Ten  germ-free guinea pigs  were
continuously  exposed to 40 ppm  of SO2 for two to  18  days
from  10 days after birth. Their pathology of paransal  sinuses
was compared with that of 11 germ-free pigs reared under con-
ventional conditions. Mucous membranes of paranasal  sinuses
of the guinea  pigs not exposed to SO2 were in a static or silent
state, which proved that no  reaction  occurred against stimulus.
Since pus was seen in all the nasal sinuses of guinea pigs ex-
posed to  SO2, and desquamation  of epithelium was observed
in the mucous membrane of the respiratory tract, the mucous
membrane probably undergoes necrosis from higher concentra-
tions of SO2. Hyperemia and congestion of blood vessels and
neutrophils were observed which proved acute inflammation,
Hyperplasia of mucous membrane,  increase of inmature cells,
and infiltration under mucous membrane were not seen.  A
long-term experiment under low concentrations is  necessary
for a more accurate air pollution study. Changes were found in
the respiratory tract; no difference was seen in the paranasal
sinuses of the two groups of guinea pigs. Although the mucous
membrane  of  human sinuses is anatomically different form
that of guinea pigs,  SO2 would  probably be  toxic  to human
bodies,  judging  from  the  fact  that  acute  inflammation  is
caused by  SO2 and  that patients with paranasal sinuses dis-
eases frequently come from contaminated districts.

Health   examinations  were  undertaken  on  infants  and
schoolchildren in Fuji City, a highly polluted area in Shizuoka
prefecture. The correlation between die prevalence of infantile
asthma  and air  pollution is  discussed.  According  to sulfur
dioxide  levels, Fuji  City was divided into a highly polluted
area (SO2 mean concentration in a year was 0.05-0.07 ppm), an
intermediate area (0.03 -  0.05 ppm), and » low pollution area
(below 0.03 ppm). Schoolchildren  were selected elementary
schools in the  three areas by a questionnaire or nurse-teacher,
and diagnosis of asthma was ascertained by detailed examina-
tions. Fujinomiya City, adjacent to  Fuji City,  was selected as
the control area. The  prevalence value of asthma in schoolchil-
dren in 1968 was high in  the highly polluted area; however, a
statistically significant difference was not recognized between
this area and the other two areas. The prevalence of asthma in
children  in the highly polluted area in 1970 was about three
times that in the lowest polluted area, and its difference was
significant. The prevalence of asthma in the intennediarily pol-
luted  area  showed a medium value between  the highes and
lower polluted areas. A significant difference was statistically
reocognized between the highly and  intennediarily polluted
areas. The prevalence of asthma curve in the lowly polluted
area intended to become lower as the grade  increased,  while
the curve in the highly polluted area showed two peaks in the
third and fourth grades. The difference between low and high
values was  remarkable. The  prevalence  of  infantile asthma
was investigated  on 325 infants in two highly polluted districts
in Fuji City. Its  prevalence was  five or ten times that in the
Ichihara  district in Chiba prefecture. Thus, the prevalence of
asthma in each grade of children in Fuji City is highest in the
polluted area,  and  it has a tendency to keep pace  with SO2
concentrations.

Vital  capacity of the lungs was determined by a  Barnes
spirometer in a group of 88 healthy persons, 58 men  and 22
women, between 18  and 30 years of age. Three methods were
employed: the vital capacity of the lungs was measured in the
classical way, with  the open nose; with a closed nose; and
while  the  person investigated  made the  deepest inhalation
through his  nose while  having his mouth  closed, and  the
deepest exhalation through  his mouth, having his nose  closed.
The vital capacity of the lungs determined by Method n was,
on the average, smaller by  360 cu cm than the  capacity deter-
mined by the classical procedure.  In another part of the ex-
periment, fifty healthy men were exposed to an  environment
which  contained  hydrogen sulfide  before  calculating  vital
capacity. The observed reduction of the lung vital capacity in
an environment of air irritating the respiratory tract is real and
statistically significant.

The effect of air pollution on human health was evaluted from
the viewpoint of immunogenetics. Data obtained at several ci-
ties in Yamaguchi Prefecture during 1945-1969 were analyzed
in terms of the pollutant concentration and mortality rate. The
components of the deposited paniculate matter were classified
into  two  groups,   soluble and insoluble substances,  and
analyzed in  relation  to the mortality rate  by bronchitis,
asthma, and  heart diseases. The  plotting? of the  corrected
mortality rate versus the year and the amount of soluble or in-
soluble substances showed  remarkable correlation. The mor-
tality  rate  was also  analyzed in relation to the degree of at-
mospheric   pollution   (SO3   in   deposited   paniculate
matter/square root of the amount of precipitation). Using the
data obtained during 1960-1969.

Environmental contamination by paniculate substances was
studied including the condition of air pollution by particulates,
their effects,  and their measurement methods. The paniculate
substances studied were less than 10 micron in diameter. Prin-
cipal reports of studies on  paniculate substances, the concen-
tration of paniculate substances,  the effects of co-existing
substances, and environmental standards in foreign countries,
were studied based on the literature. The concentration of par-
ticulate substances  should  always  be determined under the
conditions: the average value for 1 hr in 24 hr is below 100
micrograms/cu m; and the  value for any 1 hr is below 200
                        micrograms/cu  m.  These  conditions  should  be  regularly
                        checked and amended according to the  result. The effects of
                        sulfur dioxide are also discussed.

                        Threshold levels of acrolein perception were determined to
                        help in setting maximum allowable limits of concentration. The
                        threshold level of  its odor perception was 0.8 mg/cu m for
                        most sensitive persons. The thresholds of acrolein reflex effect
                        on optical chronaxy was at 1.75 mg/cu m, on  rhythm and am-
                        plitude of respiratory movement at 1.5 mg/cu m, and on  eye
                        sensitivity to  light  at 0.6 mg/cu  m. Based on these data, the
                        proposal for maximum allowable concentration in the ambient
                        air was set at 0.3 mg/cu m. The present level established for
                        working areas (two mg/cu m) caused irritation of the conjunc-
                        tive and nasal mucosa, lowered eye  sensitivity to light,  and
                        elicited changes in the rhythm and  amplitude of respiratory
                        movements. Air quality measurements in the  area  around  oil
                        drying  plants  determined concentrations of acrolein in excess
                        of the allowable limits even at 1000 m from the plant. (Author

                        tions of chlorine to help in determining maximum allowable
                        concentrations for inhabited areas. The  air of the plant was
                        continuously polluted with chlorine and the air of the city con-
                        tained  a continuous supply  of free chlorine even at compara-
                        tively great distances from the source of discharge. Chlorine
                        was  correlated with meteorological  variables. The effect of
                        chlorine on human health was investigated. The threshold of
                        chlorine odor perception for sensitive persons was 0.5 mg/cu
                        m. The threshold of chlorine effect on reflex activity as deter-
                        mined  by changes in eye  sensitivity to light was identical.
                        Thresholds as determined by respiration and optical chronaxy
                        were  1.5  mg/cu m.  The  maximum  allowable concentration
                        adopted by the USSR was 0.1 mg/cu m, a value considerably
                        below   the  established   thresholds.   (Author  conclusions

The threshold reflex effect of simultaneous sulfur dioxide and
sulfuric acid aerosol exposure was investigated to recheck the
standard limits for the simultaneous presence  of two or more
pollutants.  The simultaneous inhalation of  SO2  and H2SO4
aerosol  in  above-threshold  concentrations  elicited  reflex
changes  in eye sensitivity  to light and in optical chronaxy
which  approximately equaled the  sum  of  changes resulting
from individual exposure to the pollutants.  The simultaneous
effect in concentrations  equal to the allowable concentrations
(0.05 and 0.03  mg/cu m) on the curves of adaptation to dark-
ness or in  the optical chronaxy curve on man was nil. The
synergistic effect of simultaneous exposure was active only in
concentrations  exceeding  the  maximum  allowable  limits.

The effect of dichloroethane on human health was investigated
with respect to threshold concentrations to determine values
for  maximum  allowable  concentration limits. Dichloroethane
vapor threshold odor perception was 23.2 mg/cu m for most
persons and 17.5  mg/cu  m for highly sensitive persons. The
threshold effect of the vapor concentration on the functional
state of the optic analyzer was 60 mg/cu m; concentrations of
6.0, 9.0, 12, 17.5, 23.2,  25, 30, and 50 mg/cu m lowered the
sensitivity of the optical analyzer to stimulation by light. Tests
of the threshold effect of dichloroethane on vascular reactions
and respiration (6.0 mg/cu m)  determined  the maximum  al-
lowable  concentration at 4.0 mg/cu m. (Author  conclusions

Exposure of the human organism to lead concentrations of 1
microgram/cu  m air causes, in the long run,  an increased
discharge of coproporphyrin, i.e.,  in effect a disturbance of
the  metabolism. A similar  effect is  achieved by a carbon
monoxide concentration of 2 mg/cu m. Concentrations of  Pb
and CO of the above magnitude are found in the atmosphere
more than 50% of the time. The present methods of ventilation
of homes and  offices are ineffective,  so such concentrations
are  also found indoors. The Institute of  Climatology  is
presently conducting measurements, which are at the moment
limited to sulfur dioxide, CO, Pb, aerosols, and aldehydes, for
determination of the pollutant concentrations in the air which
begin to affect the well being of man.

Patients which colds,  acute  bronchitis,  asthma broncbiale,
bronchitis with asthmatic attacks, chronic bronchitis, pharyn-
gitis, and  allergic rhinitis in Fujinomiya City and Shibakawa-
cho were examined during March 1969 and February 1970.
These two districts are contiguous to Fuji City where serious
air pollution is caused by many paper manufacturing factories.
During the  investigation,  monthly average concentration of
sulfur dioxide was 0.023 - 0.037. Morbidity of acute bronchitis
in these  districts  was  lower than that of Fuji City, but
bronchitis with asthmatic attacks was the same as in  a non-
polluted district of Fuji City. Though the effect of air pollution
of Fuji City was clearly observed in Fujinomiya City  a cor-
relation between  meteorological conditions, observed  at the
same  time,  and occurrence of  respiratory diseases  was not
found.

Deaths in Yokkaichi District from 1961 to 1969 were classified
according to death certificates by year, area, cause, age, and
sex; comparison between polluted and non-polluted areas and
the correlation with air pollution were investigated. In the pol-
luted  area compared to the non-polluted areas, the mortality
due to malignant neoplasm tended to be high; the mortality
due to damage on blood vessels  of the central nervous system
tended to be low. In mortalities due to total heart diseases,
total  tubercular  diseases,  and  pneumonia, the  difference
between both areas was not clear. While the mortality  due to
bronchial asthma decreased year after year since about 1966 in
the non-polluted area, it tended  to increase year after year in
the polluted area; on the average in 1967 and 1968, a signifi-
cant difference  at 5%  risk  was  evident. The correlation
between mortality due to obstructive respiratory diseases and
sulfur dioxide from 1967 to 1969 was significant at a risk of
5%.

The effects of smoke and dust were investigated for five years
since  1965 with respect to school children in Chiba, Mie, and
Osaka (nine schools with a total number of children of 23,048)
and the data were examined.  Respiratory function tests with
children of non-polluted schools  (average value  of sulfur diox-
ide) measured by the lead dioxide method from January 1964
through April 1968 was below 0.3 mg/day/100 sq cm) in each

sured by Vitalor as indicated by the following formula where
body height is expressed as X and age as Z: Y  equals (0.44 +

3.01Z)X - 345.33Z +  1244.12 in  girls. The difference between
the values obtained  from the above calculation and  actual
measurements was within the range of observational  errors
both in boys and girls. It was found that 1,  0.75, and 03

between  actual and expected values of forced vital capacity
became larger and the frequency of values below the expected
one increased with an increase of pollution level. The  dif-
ference of mean values of timed  vital  capacity corrected for

Human subjects were tested for the effects of  brief exposure
to formaldehyde, and albino rats were tested for the effects of
                         long-term exposure. Reflex changes  in the human organism
                         were evaluated by determining olfactory thresholds and the ef-
                         fects on cerebral biopotentials (with electroencephalograms).
                         In 7 of 15  subjects, the minimum detectable and subliminal
                         formaldehyde concentrations were 0.0073 and 0.054 mg/cu m,
                         respectively. The remaining subjects had higher thresholds. In
                         five of the  subjects with the lower thresholds, 0.04 mg/cu m
                         formaldehyde had  no effect on  cerebral bioelectric activity.
                         However, 0.053 mg/cu m formaldehyde produced statistically
                         reliable changes in all five subjects. Inhalation of  1 mg/cu m
                         (the maximum permissible concentration in industrial air) and
                         3 mg/cu  m formaldehyde  by abino rats for three  months
                         produced mild cytological and cytochemical alterations in the
                         liver and brain against a background of moderate  hyperemia.
                         There was also a syndrome of intensified functional activity of
                         the thyroid gland  and adrenals,  which is the morphological

                         ganism exposed to  adverse environmental factors. Exposure to
                         0.012 mg/cu m formaldehyde (the mean diurnal MFC  for at-
                         mospheric air) produced  no detectable changes in the animals.

Sulphur dioxide and fluorine compounds are  well-known pol-
luting agents. In many industrial areas in France they  are the
cause of  appreciable  damage to the  surrounding vegetation.
The appearance and the morphology of the burns vary accord-
ing to the  polluting agent involved; moreover,  the climatic con-
ditions have a preponderating influence on the extent of the
damage  observed.  The absorption rates of the two polluting
agents have been  studied and there is an important difference
between the  two  gaseous pollutants. After having been  ab-
sorbed,  sulphur dioxide and the fluorine  compounds  behave
differently in  the plant. This may  be explained by the fact that
sulphur  is a normal  metabolite  of the  plant, whereas  the
fluorine  ion is irrelevant to it and does not therefore take part
in any normal  metabolic process. It accumulates in  certain
definite  parts where it could cause necroses when a  certain
level has been overstepped. (Author abstract)

Very close study of vegetation makes it possible to reduce a
pollution by examining only the canker or burning which this
examination shows occurs on the vegetation around the sta-
tion- herbaceous flowers, shrubs and trees. The time at which
such a programme should  start must be  judiciously decided.
The possibility of proceeding with  sampling and analysis of
leaves or (pine) needles remains. It appears that in the USA
the tendency is to establish a single pollution by chemical anal-
ysis of the air which, incidentally, does not provide informa-
tion  on the damage caused to plants and  animals.  In the
USSR, on the contrary,  Dr.  Izmerov  takes examination of
vegetations as the basis for determining  air quality. The author
thinks that this latest type of study requires sustained atten-
tion, and sense of observation, extensive knowledge of vegeta-
ble biology, and  of the  kinds of  attack to which various
vegetable forms are liable. It makes it possible to  place diagno-
sis of pollution-by  fluorine (compounds) on firm basis. (Author

The functioning of chlorophyll in the course of photosynthesis
in leaves of plants serves as a method of air purification of
sufficient  importance to  consider its use in  control. Vegeta-
tion, like men and animals, can sustain  a considerable amount
of damage to the point where the threshold limit  of absorption
of toxic substances  is exceeded. The three gases causing the
most damage to vegetation are carbon monoxide, the  sulfur
oxides, and  those containing fluorine. Also to be considered
are acid 'smog', toxic  'smog', ozone, and  nitrogen oxides.
Other industrial pollutants  which have  a  toxic influence, but
less  sever  and  localized,  are  dusts,  hydrogen  sulfides,
hydrochloric acid, etc. Ethylene and carbon monoxide cause
great damage to the  growth hormones, particularly auxin. The
effects of SO2, SO3, and H2S04 are related to the quanity of
gas emitted, the degree of resistance of  the species, their state
of development,  and the  various environmental conditions.
The sensitivity of  vegetation to the action of sulfur gases va-
ries essentially as a function of the speed  of absorption of the
gas by the leaves.  Through experimentation it has been found
that the plant  species which are  most sensitive to SO2 are
chickweed, alfalfa, barley, oats, wheat, rhubarb, lettuce, en-
dive,  spinich,  cabbage,   and tobacco.  Apples,  apricots,
peaches, grapes, com, and beans are less sensitive, whereas
the floral species such as gladiolus,  rose, and lilac offer con-
siderable resistance.  Aquatic vegetation is often  used as puri-
fying means for polluted streams. Subsoils purify themselves
of pollutant materials in various  ways, including uptake by
vegetation and dispersion in the soil with  rain water, etc. In &

This paper reports on the state of the arts concerning control
and scrubbing  equipment for fluoride inside  working premises
as well as  directly  from electrolytic furnaces. Far reaching
research has improved the already very effective methods and
installations. An optimal aerodynamic air ventilation is used
very effectively.  Control of dust  and gaseous components,
measurements  of fluorine from the  air inside  of working
premises and from the exhaust are done separately. Measure-
ment and control is accomplished according to  VDI-Richtlinien
(guides) No.  2093 and  2452.  The  success of reduction  in
fluorine content with the installation of control equipment can
be measured by the reduction of the fluoride content in grass,
in the vicinity of the plant, which is used as cattle  feed.

In the Ruhr valley, a study of the distribution of lichens was
performed with  the aim of  answering the  question whether
lichens are useful indicator plants for air pollution. In  urban
areas,  25,000  trees  were  surveyed  and their coverage  by
epiphytic lichens  evaluated. Three zones were distinquished:
lichen  deserts, coinciding with  industrial areas,  a zone of
struggle, and zones populated by lichens. It could not be safe-
ly established  whether air pollution  alone is  influencing  the
distribution of lichens-. Rather, a combination  of  air pollution
and  city climate with its lower humidity and  higher tempera-
tures is more likely responsible. Experiments are  suggested to
determine  detailed   environmental  factors   influencing  the
growth of lichens. Four  maps and six tables illustrate climate,
air pollution, and lichen distribution in the Ruhr valley.

The  resistance of different plants to exposure with sulfur diox-
ide in  concentrations varying  from 0.15 to 0.8 was studied.
Long range tolerance limits were determined  in a range from
0.15  to 0.4 ppm for different plants. Also the  effects of short
duration exposures, the  importance of time  intervals between
exposures, the effects of duration of  exposure and concentra-
tion, and the combination of toxic and subtoxic concentrations
 vere determined. For a given amount of gas an increase of
                         non-exposure period and an increase in impulse frequency of
                         gas exposure were found to prolong the threshold period after
                         which irritation occurs.  Concentrations below the  threshold
                         value  were  found to enhance  the  effect  of concentration
                         peaks. In all cases a strict distinction had to be made between
                         continuous and intermittent exposure, the latter allowing recu-
                         perative pauses within  certain ranges  of concentration. The
                         plants were  divided into the following groups according to
                         their resistance as well as their tolerance: 4) clover type cattle
                         feed, 2) cereals, and 3) rape, cabbage etc. Individual SO2 im- ,
                         missions cannot be treated by a simple additive process in the
                         determination of gas effects  on plants. The manner of their
                         distribution over the dirunal  period must be  taken into ac-
                         count, along with biological and meteorological  factors.

                         trees are  summarized. The sulfur content of  tree leaves, as
                         determined by the barium sulfate gravimetric method, was
                         positively correlated with atmospheric sulfur oxide concentra-
                         tions measured by the lead dioxide method. The effects of sul-
                         fur dioxide on the germination of pollen grains  were relatively
                         minor. Correlations were observed between  the degree of  air
                         pollution  and the growth,  sturdiness,  and autumnal tints of
                         trees. In the case of ginko and platanus trees, there was an in-
                         timate correlation between sturdiness and leaf color and the
                         amounts of dust and S03 on the leaves. However, the damage
                         appeared  to occur by a different mechanism in each species.

                         Open-housing raising of cattle was investigated at 7 farms. Ef-
                         fects of environmental conditions (temperature, moisture con-
                         tent and purity of air) on the physiological state and produc-
                         tivity of  cattle raised under  various conditions (tents, camp
                         sheds, winter barnyards) were studied. Evaluations were made
                         in terms  of physiological indices: pulse frequency, breathing,
                         heat release and day and night milk yield. An investigation was
                         made of  pulmonary  gas  exchange with  the aid of respiratory
                         masks. The corresponding data,  relating temperature, number
                         of respiration and heat release, are tabulated and an optimum
                         24-'our time schedule is proposed, based on  8-hour periods
                         between milking and presumed night pasturing. The average
                         annual  milk yield of cattle under examination amounted to
                         4,000 to 5,000 liters under 40  to 50 per cent open-housing con-
                         ditions. Summer camps  necessitate the erection of adequate
                         enclosures, because on cold or rainy  days, or at night, the
                         keeping of cattle in the open air decreases their milk yield.
                         Winter barnyards may be also used, if necessary, on hot or
                         cold days to provide cattle with rest. The barnyards  then have
                         to be constantly ventilated to prevent a detrimental rise in
                         temperature, and moisture and ammonia content of air.

AN  INCIDENT OF  DERMOPLAKIA  PARALYTICA  AL-
BICANS AFTER TREATMENT  OF  MANGE  WITH GAS.
((Bin Fall von Dermoplkia paralytica albicans im Anschluss an
Raudebegasung.)) Text in German. Berlin Muenchn. Tieraerztl
Wochschr., 8:156-157, 1951.
Through the  treatment of mange with gas the skin  is some-
times injured. This is caused by a reaction of sulphur dioxide
with the moist skin (SO2 + H2O = H2SO3). In the spring of
1946 a  fifteen year old mare  was treated with SO2 against
mange.  About eight weeks  later  an eczema developed which
was  treated  with  some sort of  cream. The eczema healed
within six weeks. Four months after the treatment with gas,
spots of white hair of the size  of a coin were observed which
enlarged rapidly and after 30 months the entire area  from the
knee upward was affected. About 32 months later the fanner
observed some  difference in the  movement of the right leg as
compared to the left, 36  months later  frequent stumbling.
After another six months the horse fell when it wanted to turn
and it could not lie down any more but rested using the wall of
its stable as  support. In the 46th month the farmer had to
slaughter his horse. Two X-rays  and  an illustration of the
spread of the disease are given.

In horses,  cattle and pigs the  content of copper, manganese,
zinc and magnesium was determined  in the pituitary, adrenal,
thyroid, pancreas, ovary and thymus, and the mean values and
standard deviations were determined. Within the same animal
there were  considerable variations of  each element as between
the different endocrine  glands  and similar significant dif-
ferences from one  animal to another.  These results are not ex-
tensive  enough  to permit any conclusion on the relationship of
the examined elements to the  endocrine function or their in-
fluence  on the enzyme activity.

AIR POLLUTION BY  FLUORIDE COMPOUNDS NEAR AN
ALUMINUM  FACTORY.  Fluoride Quarterly, J.  Intern. Soc.
Fluoride Res., 2(l):28-32, Jan. 1969.
From 1958 to 1965, contamination near an aluminum factory in
the vicinity of  Bratislava, Czechoslovakia, averaged 0.14 mg
F/cu cm. This average represents a fivefold increase above the
maximum allowable concentration of 0.03 mg  F/cu  cm. The
gaseous fluorides HF and  SiF4  constitute  39% of  the  fluid
values- in the air near the plant  as compared to 61% solids,
namely  CaF2, NaF, and Alf3.  The proportion varies with the
distance from the factory: at an area 8 to 9 km from the facto-
ry, 15% solid and 85% gaseous F compounds were present in
the atmosphere. The relative increase  in gaseous compounds is
apparently  due to sedimentation of  the  solid  F compounds
near the factory. Values of the  yearly F fallout in  the  con-
taminated area  were 44  to 7337 kg sq km. F values  obtained
for soil  in the area of the factory were  135  mg/100  g (1350).
This is  4 to 7 times higher than the  usual F content of soil.
Grass near the  factory contained F values as high as 133
mg/100  g  dry   substances.  While running surface waters
showed  only slightly increased  F levels,  standing  surface
waters contained as much as 10.9 mg/1. Determination of F
fallout and of F content in plants and biological materials is
the best means of assessing long term effects of fluoride emis-
sions. Meteorological influences appear to be less significant in
evaluating F damage. The composition of soil, the presence of
F  dust on  plants,  and the F content of flowing and ground
waters are of little use in determining  F damage to  human,
plant, and animal life.

To separate the effects of prior exposure to sulfur dioxide and
of higher sensitivity to  SO2 in evaluating results of SO2 expo-
sure tests, measurements of intensity of assimilation and trans-
piration and of smoke  resistance of plants should be carried
out independently on specimens grown in smoke-free environ-
ments. Accordingly, twigs cut from 16 clones of 12-year old
pine tree grafts were  subjected to shock-gassing by a previ-
ously described method and  ranked according to their smoke
resistance.  The  most  and the least resistant  clones  were
selected  for subsequent tests in (1) SO2-free air and  (2)  air
containing 0.4, 1.5, or 3.0 ppm of SO2. In (1), May shoots cut
from either kind of clone were trimmed under water and kept
standing in water for two or three days, after which their gas
exchange was measured in  the laboratory  with  coupled  in-
frared absorption spectrographs. In (2), individual intact twigs
of either kind of clone  were gassed with SO2-containing air in
situ, and their CO2 assimilation was measured by a previously
described method. In  (1), the net assimilation intensity  of
either kind of clone showed no significant differences, that of
less resistant  clones tending to be  higher while exhibiting
wider individual variations. In (2), the depression of net as-
similation due to shock-gassing sets in sooner in the less  re-
sistant clones; also, at higher SO2 content,  the depression is
more intense and the recovery is slower than in the more  re-
sistant clones.

A  history of smoke injuries in the past 80 years in the Burk-
hardtswald forest near Aue,  East Germany, is given,  along
with an evaluation of the protective measures which have been
taken. The prevailing  species in  the Burkhardtswald  is the
spruce, although the climatic  conditions are not the best for its
growth. It is an area of moderate precipitation, almost not suf-
ficient for  coniferous trees. The entire forest is subjected  to
average  SO2 emissions of 0.20 mg/cu  m,  mainly stemming
from combustion of coal. For the past 30 years, extensive ar-
senic emissions have also affected the area. Their contribution
to  smoke injuries of trees has not yet been studied. Smoke in-
juries from SO2 on spruces and firs were observed in  the
forest as early as 1860; older trees were particularly affected.
For the past several decades, dead or severly  injured spruces

and firs have been replaced by fast- growing Weymouth firs,
red oaks, and birches. Unfortunately, no plan was established,
so that in some areas,  less valuable birch groves developed.
Cultivation of Pinus nigra in this area is still in the experimen-
tal stage. In  the future, Japanese firs will also be planted. On
the average, it was found  that beech trees are growing very
well in the area, and no smoke injuries have been observed on
them.

Pollution of  plants growing on a hill by cadmium, zinc,  and
lead present in waste gases from a mine refinery was deter-
mined by atomic absorption spectrophotometric analysis of the
elements following their extraction from  dried and ashed plant
samples.  Plant distance from the refinery ranged from 400 to
2500 m,  and plant content of metals varied with distance. Cad-
mium  levels ranged from 17 to 3.3  ppm and zinc from 2590 to
360 ppm in mulberry leaves. The  cadmium content of moss,
greens,  and  eggplant  leaves  collected  at  700 m from  the
refinery  varied from 41 to  61 ppm and the zinc content from
2620 to 7010 ppm. Values were lower in corn, tomatoes,
pumpkins, and persimmons. Taro, carrots, Welsh onions  and
burdochs showed medium values.

Two kinds of symptoms typical of injuries  caused by sulfur
dioxide  as H2SO3 were observed on  the  leaf  blades  and
sheaths  of paddy rice; one was multiple brown spots and the
other was white lesions. These symptoms were observed at the
leaf tip, between the veins, and sometimes at the edges of the
blades and sheath. To  prove  that these symptoms were ac-
tually due to SO2, rice plants were sprayed with H2SO3 solu-
tion both during the day and at night. Only brown spots were
observed; decrease in chlorophyll was directly proportional to
the amount of acid sprayed, and the most severe damage was
inflicted on the leaves in the third and fourth position from the
top. Sulfur content was higher  in leaves sprayed during the
day than in those sprayed at night.

RESULTS OF THE MEASUREMENT OF SULPHUR  DIOX-

                        The concentration of sulfur dioxide was measured on different
                        days to compare the level of emissions with the state of the
                        woods and to observe the changes in concentration levels as a
                        result of new emission sources. Emissions considered were
                        SO2 levels above  0.01 mg/cu m. Measurements  were taken
                        with polarographic - coulometric analyzers beginning in 1966 in
                        five  regions  which ranged  from  undamaged  to  heavily
                        damaged fir copses. Measurements were taken at 30 minute in-
                        tervals for one year. During  measurement, the  influence of
                        emissions from a new thermal plant was seen on undamaged
                        copses as the conditions grew worse. The results proved that
                        there is a relationship between the damage of the copse  and
                        the emission level.  It was verified that fir copses  are damaged
                        by lower sulfur dioxide concentrations than expected. To ex-
                        press all the factors that are influential in damaging plants,
                        measurements based on an analysis of air samples abstracted
                        during a longer time period are necessary.

                        Sulfur dioxide exposure experiments were performed in small
                        plastic greenhouses  where various  types of fodder plants
                        (clover, grass, rye, etc.) were grown either in pots or in the
                        soil.  Various SO2  concentrations and exposure  times were
                        selected. In  the  first experiment, clover (Trifolium pratense)
                        and grass (Lolium  multiflorum) were exposed for 9 hours to
                        SO2 concentrations of 1 mg, 2 mg, and 5  mg/cu m air. While 1
                        mg SO2 had no effect on the plants, 2 mg clearly  retarded
                        growth of the clover. The grass showed a reduced growth rate
                        only at 5 mg, whereas the  clover growth rate  was already
                        down to 37% that of the control. This selective effect of SO2
                        could be confirmed by other experiments with  Vicia villosa
                        Roth, Trifolium incarnatum L., and  Lolium multiflorum. The
                        first two plants experienced extremely retarded growth, while
                        the last grew  satisfactorily. The shift in the composition of
                        plant communities  becomes more pronounced at higher SO2
                        concentrations. Resistance of the plants to air pollutants varies
                        with their developmental stage. Exposure to SO2 of Vicia vil-
                        losa  Roth, and Avena saliva L., which were both in  an early
                        developmental stage,  showed that  the  latter was  damaged
                        much more in the eight-leaf stage than in the 3-leaf stage. The
                        Vicia villosa growth rate was greatly  reduced, while oats
                        produced more chlorophyll. A study of the yield of clover and
                        Lolium multiflorum grown together  and separately showed
                        that  the former had a lower yield in both cases, and the latter
                        had  a higher growth rate in the mixed bed than when grown
                        alone.

Manganese acts on the reproductive capacity of animals and is
required  for growth. The physiological action of  copper,
cobalt, and  manganese on the content of trace elements and
more abundant elements in the secretion of  the parotid glands
in sheep was investigated. The experiments were performed in
series.  In the first series, the separate effect of each element
was  studied. In  the  second  series, complex supplementation
with Cu +  Mn + Co was carried out. The  elements found in
saliva were  Na,  K, Ca, Si, Mg, Al, P, Cu, Mn, and Ti. The
content of  Na, K, and  Si in the saliva in  all series did  not
change. Introduction  of Co increased Ca and  Cu content and
decreased P, and had no effect on Mn. After Co supplementa-
tion  was stopped, the content of Ca, P, and Cu  in the saliva
increased slightly.  The addition of Cu increased Mg and Cu
content. After Cu  feeding was  stopped, Cu and P decreased
and dropped to the original level. The addition of manganese
to the  diet  has no effect. Combined feeding has  no effect on
P, Ca,  and Mn content of the saliva, but the amount of Cu in-
creased, even  after supplementation stopped.  Cobalt  was  not
found in the saliva in any of the cases.

A  STUDY  OF THE  INTAKE  OF TOXICANTS THROUGH
THE BARK OF TREES. (Ueber die Aufnahme von Schadstof-

Tech. Univ. Dresden. ll(3):549-552,1962. 12 refs.
The  retention  of fluorine  and its compounds in the bark of
trees is discussed. Analysis  of  the barks of willows, poplars
and  alders  stemming from the vicinity of  a  superphosphate
plant showed  considerable amounts  of fluorine; hardly any
traces  were found in the  wood. The  quantitative analysis of
fluorine by perchloric acid distillation showed that a  relation-
ship exists  between  the fluorine content in the bark and the
distance  of the  emission  source.  Gassing  experiments with
hydrofluoric acid  on three-year old barren  trees  and  cut
branches in the winter showed that the fluorine content rose to
between 33  and  65 mg in  100 g dry substance, depending on
the exposure time; 1.71  to 4.28 mg fluorine was  found in the
wood.  In non-exposed trees, fluorine concentrations of 0.9 to
1.6 mg in the bark and 0.2 to 0.3 mg in the  wood were found.
A  further series of gassing experiments with trees during the
winter period  showed that the fluorine content of the leaves
was  twice or three times as high as that of non-exposed trees.
Maple  leaves from trees whose bark was treated with a  2%
sodium fluoride  solution also showed an  increased  fluorine
concentration.  Trees  in the vicinity of a tar and asphalt plant
stored  higher  concentrations  of tar containing substances in
the bark and, to  a less extent, in the wood. Barren trees in the
winter  were exposed to  ammonia. NH3 could  be found in the
bark; it was not found in the wood.

EXPERIMENTAL  STUDIES OF PHVTOTOXIC HYDROGEN
FLUORIDE  CONCENTRATIONS.   (Experimentelle  Unter-
suchnungen  ueber  pflanzenschaedigende  Fluorwasserstoff-
Konzentrationen).  Text in German.  Forschungsber.  Landes
Nordrhein-Westfalen, no. 2017:54p., 1969. 48 refs.
The resistance  of important plant cultures to hydrogen fluoride
and the HF concentrations which cause plant injuries at long-
term exposure  were determined. The test plants were  exposed
to certain HF concentrations in small plastic greenhouses. Stu-
dies  of the  resistance of certain agricultural and forest plants
lead  to the formation of various resistance  groups which  are
important for diagnosis as well as for the selection of plants
for cultivation in HF polluted areas. For diagnosing purposes,
the resistance groups were established with respect to leaf re-
sistance; the yield was used as a criteria for establishing re-
sistance groups in the planning of  plant cultures. Tuberous
plants e.g., tulips,  crocusses,  narcissas, etc., are not  suitable
for cultivation in HF polluted areas. Peas, beans and lupines
showed a higher yield reduction than oats, corn, and summer
rap. HF pollution might lead to drastic changes, such as reduc-
tion of less resistant plants which in  turn enhances the growth
of resistant species. Concentrations of 1 to 2 microgram HF/cu
m caused severe injuries in tuberous plants after several days
of exposure.  In  grasses  and various types  of  clovers, a
fluorine accumulation of 9 mg/100 g dry  substance was found
at a 16 day exposure to an average concentration of as little as
0.85 microgram HF/cu m. Winter barley showed a yield reduc-
tion after 12 days of exposure to 3.3 microgram HF/cu m.
Oats,  lupines,  and peas showed a growth retardation at con-
centrations above 4 microgram HF/cu m. Spruces, Weymouth
pines, Japanese lark, and Nordmann hemlocks began to show
needle injuries after  several days of exposure to concentra-
tions between 1.5  and 4 microgram HF/cu  m. Older leaves
generally showed  higher fluorine accumulations  than young
ones.

DETERMINATION AND PREVENTION OF AIR POLLUTION
DAMAGE TO FORESTS  IN  THE  CZECH  PART OF THE
ERZGEBIRGE.  (Forstliche Massnahmen zur Erfassung  und
Verhuetung von Waldrauchschaeden  im tschechischen Teil des

Spruce trees in the forest areas of the Erzgebirge were found
to be extensively damaged by sulfur dioxide present in smoke
from open coal pits and coal processing plants. Trees located
in exposed areas  such as ridges and plateau  swamps were
especially sensitive. Atmospheric sulfur dioxide  concentrations
of 14.90 mg/cu m  were recorded. Soil investigations  showed
acidification of the humus layer and of  the  top layer of the
mineral soil. Sulfur concentrations  in the soil  reached up to
384 mg SO3 per kg soil. Zinc, lead, and chromium were also
present in concentrations exceeding critical  values. Counter-
measures  indicate the efficiency of  stone  meal, primarily
basalt meal, in promoting tree resistance to sulfur dioxide and
of calcium and nitrogen fertilizers in improving the quality of
the humus soil layer. Since the silicic acid concentrations are
always high in the needles of injured spruces, it is thought that
this compound might be a useful indicator of plant damage.

longs to the sandstone region of Bohemian Switzerland. In the
localities containing the individual types, basic rating data,
health conditions and quality of trees, their height pattern, and
size  of  crowns were  studied.  From  each typologic unit,  40
borings were taken by means of a Pressler borer from 20 cen-
trally located trees. The  tree ring analyses of these borings
were performed with the Eklund apparatus  with  a plotting
adapter. The  soil condition of the individual types were in-
vestigated by six soil probes. The age of spruce stands in the
long-term research area, ascertained by borings, was 75 years.
Injuries  to  trees due to industrial exhalations, smoke injury,
tree mortality, distribution of thickness growth increments in
trees with various degrees of smoke injury, and comparison of
relative  thickness growth increments  in individual units were
graphed. It was established that smoke injury, mortality of the
trees and decrease in growth are much greater on exclusively
podzol and gley soils than on ochre soils and moderately pod-
zol soils. It is indicated that the smoke damage does not ap-
pear to  be uniform in various  localities. The investigation
raised the  need for adapting  forest management  in  smoke
damage  areas to the particular features of the locality.

The possibility of whether the decrease in the formation of dry
matter could  also be caused by deterioration of the balance
between 'formation of dry matter and destruction' is reported.
A known  photosynthesis has its optimum   at temperatures
lower than those of dissimilation and thus, at super-optimum
temperatures, a  decrease in the  efficiency of photosynthesis
can arise. The  gross dry matter formation for  three various
temperatures  was determined. Dry matter formation in dark-
ness was checked and the intensity of dissimilation  was tested
by a manometric method. The gross dry matter growth incre-
ment in pure leaves rose with increasing temperatures much
more rapidly than that in contaminated leaves, which exhibited
decreased dry matter formation.  The curve of the relative in-
crease of respiration at equal temperatures indicates that the
difference should be ascribed to dissimiiatien. Investigation of
the water  supply showed that improvement of situation in
dusted leaves (increased release of water, reduced water con-
tent)  can  be  expected only under  intensive  irradiation in
laboratory conditions. (Author abstract modified)

It is  useful to adapt the existing and presently used -terminolo-
gy with  respect to plant damage to the advanced knowledge of
the art while  preserving proven concepts. Designations which
                         can be misunderstood or are unnecessary should be dropped.
                         This is true especially for the terms invisible injury and invisi-
                         ble  damage. It was suggested  that the concept of injury be
                         replaced  with respect  to  physiologic effects,  by  disease,
                         because this designation can be understood only in the biologi-
                         cal, and  not  economic, sense. It  was further  suggested to
                         distinquish  between  acute  and  chronic  diseases,  and  also
                         recognize a class  of secondary disease, together  with  two
                         kinds of damage, direct and indirect. In order to differentiate
                         clearly among the concepts involved in  the casual chain, fume-
                         damage terminology  would thus, in respect to  the proposed
                         classification, include 2 forms of effects, 3 grades of disease,
                         and 2  kinds of damage (7 terms  in  3  successive influence
                         stages). (Author abstract modified)

                         A planting experiment on 10 ha of 40  tree and  shrub species
                         which was started i!93S in an area  of  emission attack from a
                         metallurgical plant at Freidberg in Saxony was evaluated. The
                         experiment  was northwest of the plant  at 400  m above  sea
                         level on a flat plain which slopes eastward to the Mulda val-
                         ley. The basic stratum  is gray gneiss;  the soil is medium-to-
                         deep, quite loamy, and  exhibits medium sorption and nutrient
                         values. The trees and shrubs were planted in small stands, also
                         in  rows and mixed groups, or  former agricultural land.  The
                         prevailing winds  were from southwest to northwest and  the
                         growing stands were injured only slightly by the stack gases
                         from the metallurgical plant. After the beginning of the opera-
                         tion of a new zinc refinery which was located a few hundred
                         meters northwest, an increased attack  was evidence by SO2,
                         SO3, and iron oxide dust containing waste material. The iron
                         oxide  dust  did not prove  harmful.  Short-term measurements
                         gave peak values of more than 1.2  mg SO2/cu m of air. Inju-
                         ries affecting the size of leaves and fascicles, their color, with
                         necrosis and inhibition of growth of foliage  and fascicles was
                         observed. The extent of current damage was determined. Mea-
                         surements of height and circumference, together with borings,
                         confirmed the more or less large decrease in yields from vari-
                         ous representative varieties of woody plant found in the area.
                         Smoke damage on trees and shrubs, based on damage manifes-
                         tations and yield decrease, were graded and were listed.

surface of the individual tested leaved trees. Increased concen-
trations of SO2, as evidenced in autoradigrams, was observed
primarily on the tips  of the leaves and along serrated borders,
or along the edge of the leaf, mostly in narrow, but sometimes
also broad, diffuse zones. The concentration of SO2 in the tips
and borders of the leaves increased within a range of 10-100%.
The autoradiograms  indicated  that penetration of radioactive
sulfur  compounds into the leaf  tissue occurred  only  with
Ulmus effusa and Fagus silvatica. It was also established that
sulfur  dioxide  sorption was  highest with Betula  verrucosa,
Fagus silvatica, and Carpinus betulus. Sulfur dioxide sorption
decreased somewhat  with  Ulmus  effusa, Salix  caprea, and
Robinia pseudacacia.  Substantially reduced sorption was ob-
served in acer platancides, Sorbus aucuparia, Acer campestre,
and Populus nigra italica. No  definite conclusions were drawn
about the sorption of sulfur dioxide by the leaves of trees and
the migration of sulfur compounds  which arose  from  SO2
within  the  plant organism. However, it was  directly proved
that the leaves of many woody plants are really capable of ac-
cumulating sulfur dioxide in their marginal portions, even dur-
ing a very short period, from an environment which contains
non-toxic concentrations of the gas.

known resistance to sulfur dioxide was tested  by experimental
plantings in natural emission areas. In previous experiments,
the greater or lesser  resistance of larches  to smoke was deter-
mined  genetically. It seemed possible that the production of
larches  of high smoke resistance, by  means  of controlled
cross-breeding, would be promising. The planting of 468 three-
year larches was carried out in an area of extreme smoke inju-
ry. The site of the planting was almost flat and the soil was
formed from podzoled loose brown soil. Considerable damage
was caused by winter frosts and also by severe late frosts. All
plants were exposed at the same time and for the same dura-
tion to a constant concentration of 0.73  ppm sulfur dioxide.
Resistance to smoke  is conditioned genetically and is heredita-
ry. Results  also  showed  that the highest rate of injury to
seedlings was evidenced in the class of  plants with greatest
sensitivity to smoke, while frost  injuries were definitely dis-
tributed over all of  them. The hybrids originated by cross-
breeding in the presence of L. leptolepis grew more than pure
crossings  of L. decidus. They were  also less  sensitive  to
smoke. It was  concluded that growth  losses  in the areas of
heavy emissions can  be substantially reduced,  both by improv-
ing the experimental  varieties resistant to  smoke and by large-
scale selection of the most resistant units.

Prompted by serious damage to plant bulbs caused by air pol-
lution in an  area northwest of Amsterdam, the Institute  of
Phytopathological Research conducted a study in that area and
two other relatively large areas: west of Rotterdam and east of
Sluiskil  (Zeeland, near the Belgian border).  A field investiga-
tion was first made, using specially controlled flower beds  of
gladiolus and alfalfa, which  are particularly sensitive  to
hydrogen fluoride and sulfur dioxide, respectively,  these two
industrial gases being  considered the  most dangerous to plant
growth.  Distribution of the intensity of damage on the experi-
mental  plots indicated the  direction taken  by the noxious
gases, their manner  of propagation, and the extent of damage
caused.  Damaged leaves  were then  analyzed chemically  for
fluorine or sulfur content. Commercial  crops were  compared
with those experimentally grown, and crops from areas known
to be free of pollution were compared with those from the af-
fected areas. Plants  were also  'fumigated' at the Wageningen
laboratory, under simulated practical  conditions. Comparisons
were made of varieties of the two kinds of  plants  that were
known to be either sensitive or insensitive  to the industrial
gases. The freesia plant, which suffered extensive damage in
Dutch greenhouses during autum 1956, was also tested in the
gas chambers. Two varieties of tulips were tested: Blue Parrot,
which is sensitive to gases, and Preludium, which is not. Other
plants tested were barley, broad beans, kidney beans,  corn,
lettuce,  buckwheat, sugar beets, tomatoes,  loosestrife, and
knotgrass.

Detailed observations were made from 1959 to 1964 of the in-
juries to conifers caused by emissions  of sulfur dioxide and
magnesite dust from a magnesite plant that began operations in
1959. The trees were examined for coloring of fascicles, reduc-
tion in the age of fascicles, and decay. Borings were obtained
of specimen  trees; in  characteristic areas, trees were cut  for
analysis. The results of the  investigations showed  a chronic
development of injuries due to sulfur  dioxide, accompanied by
annual  declines  in  the   growth  increments  of  individual
conifers. In the area of intensive emission attacks, the reduced
growth had caused the decay of individual trees and groups of
trees. Magnesite dust appeared  to have little  effect on  the
growth pattern of the trees,  though it created shells on many
fascicles resembling  concrete. The investigations are compared
to those of beech trees similarly  exposed but which exhibited
increases in  growth increments.  It is hypothesized that  the
growth was the result of the ability  of magnesium sulfate to
act as a leaf fertilizer in trees  relatively resistant to  sulfur
dioxide.

THE INFLUENCE OF FLUORINE CONTAINING EMISSIONS
ON PLANTS.   (Die  Beeinflussung der  Pflanzenwelt  durch
fluorhaltige Immissionen). Text in German. Angew. Botan.,
vol. 40:12-21, 1966. 18 refs. (Presented at the Botanikertagung,
Bonn, Sept. 10, 1965.)
Typical symptoms of plant damage by fluorides are mottling of
the leaves, bleaching of the leaf margin and tips, and necrosis
and rolling of the leaves. The symptoms alone are sometimes
not enough to  make  a correct diagnosis. It  is  necessary to
determine the F-content  of the plant. Several  methods are
available,  such as distillation  of  the ashed substances with
perchloric acid  or sulfuric acid and subsequent  determination
of the F-content of the distillate by colorimetry or titrimetry.
The natural F-content of plants must be known.  It usually lies
between O.OS  and 2.5 mg per 100 g dry substance. A table list-
ing the  natural  F-concentrations of various types of plants is
given. Tree barks can be used for the analyses if leaf samples
are not  available. A clear difference exists of  F-concentration
between the bark facing the F-source and the bark facing the
opposite direction. To diagnose injuries, plants can be exposed
in the pots in the polluted area under equal conditions. In one
instance, the injuries were traced to sulfur dioxide rather than
F-containing emissions. This shows that a higher F-content in
the plant than is natural does not always mean that the visible
injuries  are a consequence  of the higher F-content. Soluble
NaF or KF dust on plants may reduce the chlorophyll content
of plants.  The sensitivity  of  the plants to fluorides varies and
is influenced by the site, nutrition, and the climate.

The  effects upon  vegetation of tar and petroleum products
used to harden dirt road  surfaces  were  studied. Previous
laboratory  work had  showed various tree  leaves,  grains,
vegetable  crops, and flowers to be adversely affected by coal
tar and its components, ammonia and organic chemicals such
as pyridene. Either direct exposure to vapors in a bell jar or
sprinkling  with  empregnated   dust  gave  brown  or  black
discolorations accompanied  by attacks  on  cells, photoplasm,
or chlorophyll. To determine the effects of tar under  actual
road conditions, several  streets  in the  District of  Seine,
France, were studied. Most  trees  lining tarred streets showed
harmful effects within a  period of two  years. Displaying a
stunted, crippled  appearance  and  producing poorer  young
shoots,  they  had a  significantly  higher  death  rate than did
specimens near non-tarred road surfaces.  Leaves were smaller
and fell off earlier In addition,  trees exposed to tar stored less
starch  than others and showed abnormal or  premature cork
proliferations on branches. Decorative plants  and flowers ad-
jacent to paved streets all died or suffered severe damage. En-
suing laboratory studies on elm, walnut, sycamore, and maple
trees as well as rose and lilac bushes showed harmful action to
be due to the deposition of tar-empregnate dust  on leaves and
shoots.  Sunlight was  found  to  increase  the  damage. The
deleterious effects formed in  the French study were not re-
ported in  England and Germany.  Because of the  long  period
sometimes necessary for  the effects to appear, this did not

                         mended that precautionary measures used in the United States
                         be followed. There, harmful components of tar were removed
                         before application, and tar-macadam and bituminous earth sur-
                         faces were used.

                         BY   FLUORINE-FUMES.    (Zur  Diagnose  von  Fluor-

                         An analytical  method of analysis to verify fluorine (F) damage
                         to plants is  needed because F action shows neither unique nor
                         consistent symptoms. Fluorine  compounds attack  fruits or
                         enter  plants  through  leaf  stomates   and  decompose  into
                         hydrofluoric acid, which then acts on the mesophyll or spongy
                         parenchyma.  Several microchemical methods  are used for F
                         determination, two  of which are particularly  suitable  for
                         qualitative detection in plants. In the  color method of Feigl
                         and Krumholz,  F is indirectly identified by the  analysis of a
                         process distillate for  volatile silicon fluoride. Here,  silicon is
                         identified by an analytical method imparting a blue color to the
                         solution. The  second method crystallizes F as Na2 Si F6. Both
                         techniques are shown to be  sensitive to small amounts of F,
                         0.005 mg and  0.05 mg per lOOg of dry leaves, respectively,  but
                         the latter is simpler and more direct. Experiments with various
                         plants show that in nearly  every case neither method gives
                         deceptive, false positive results from  naturally  present F. It
                         appears possible, however, to get negative results for F
                         presence  from  plants previously damaged by  F  in earlier
                         stages of development and from fruits damaged  by extremely
                         small amounts of F. Experiments  also show  that plants  ex-
                         posed  to soils  with  unusually large  amounts of apatite or
                         phosphate fertilizer containing fluorides do not pick up  de-
                         tectable amounts of A and show no F  damage. Seed germina-
                         tion is  inhibited when the concentration of a soluble fluoride
                         (e.g. NaF) is between 0.1  and 0.5 percent. Conveniently, solu-
                         ble F components from soil can  only  be detected in the few
                         cases when  toxic effects  are  present.  Thus, the simpler
                         Na2SiF6  crystallization test is recommended for standard  ex-
                         aminations, and the color test for cases where damage from a
                         minute quantity of F is suspected  and a negative  crystalliza-

In the method for determining fluorine which like most others
is  based on distillation  according to  Willard and Winter, all
error sources  have  been eliminated which  may exist  during
sampling,  grinding,  ashing,  treatment of the ash, distillation,
and concentration of the distillate. Furthermore, almost F-free
calcium oxide has been prepared which must be added prior to
ashing to a number of samples of animal origin. For the deter-
mination of  fluorine,  distilling equipment  was  used  which
operates automatically to a large extent, is easy to handle, and
was  developed in cooperation with the aluminum plant Rhein-
felden. The apparatus  for concentrating distillates with very
low fluorine contents works almost automatically.  The method
was  tested with various synthetic solutions  as well as with a
number of internationally conducted ring analyses  over several
years. Today  the method together with  the equipment is used
in many laboratories both in this  country and abroad for the
determination  of fluorine  in  organic, inorganic and other
materials.

This paper deals with the fluorine intake from the soil, and in
particular,  answers  to  the following questions  are sought:  1.
How great is the fluorine concentration of various types of
plants grown  in different soils? 2.  What effect has a portioned
fluorine addition  to the soil on  the F-concentration of the
plant? 3. Are  there fluctuations in the fluorine concentration of
the plant during  its  vegetation period?  4. Are there any con-
nections between the F-concentrations of various plant organ-
isms? All investigations were performed in vitro and are based
on the experiments on sulfur dioxide effects described by von
Guderian (1960). The sites of the investigations are Hamburg,
Biersdorf (Sieg) and Kettwig. With the majority of the experi-
ments, the experiments, the computed fluorine  concentrations
were mixed with the soil prior to sowing. To determine the F-
concentration in the experimental soils as well as in the sample
plants the method by Oelschlager (1960) was used. The same
types  of  plants  show different  F-concentrations  which
moreover do  not correlate with the fluorine concentrations of
the soils. The fluorine concentration of plants thus is not sole-
ly a function  of the  absolute fluorine concentration of the  soil.

In the period from 1961 to 1967 fluorosis was experimentally
induced in  test cattle by feeding them primarily with locally
grown, fluorine-containing forage to which sodium fluoride or
cryolite had been added. The total fluorine intake by the NaF-
fed cows  was  1.94 mg F/kg body weight per day, and  by
cryolite-fed cows 2.48  mg F/kg body weight per  day. The
fluorine intake thus exceeded the threshold value of about 1.75
mg F/kg body weight per day given in the pertinent literature.
Fluorine elimination with the feces was found to be about 0.5
g of F per  animal per day with NaF-fed  cows and 0.9 g of F
per animal per day with cryolite-fed cows.  Along with  the
urine, 0.45  mg of F per animal per day were discharged  by
NaF-fed cows and 0.3 mg of F per animal per day by cryolite-
fed cows. The analysis of  tail  vertebrae biopsies yielded a
fluorine retention of 245 to 890 mg F/100 g ash over the period
from 1960 to  1966 for the NaF-fed cows, and of up to 655 mg
F/100 g ash for the cryolite-fed  cows. The clinical symptoms
of fluorosis were slight  to moderate yellowish, brownish spots
as well as hypoplasia of the incisors, furthermore, weak and
temporary  functional disturbances of the motility  were  ob-
served with some cows. The severity of these clinical symp-
toms were  found to be dependent on the degree of fluorine
emission. The general physical condition as well as the produc-
tivity of the test cows were in most cases satisfactory to ex-
cellent. Observations concerning spontaneous fluorosis in the
Rheinfelden (Baden) emission area during the past 15 years
show that the number and the severity  of the disease in six
communities  had  reached a peak in 1958 from whereon a
steady decrease of the number of cases  is  found. This
downward trend was parallelled by a decrease of the average
fluorine  content  in the locally  grown  forage  below  the
tolerance limit.

The resorption and retention of fluorine contained in three dif-
ferent  substances such as NaF,  fly dust from an aluminum
plant and soil intermingled with fly dust which probably  un-
derwent a  secondary fluorine reaction.  All substances con-
tained a fluorine compound with  a relatively high water solu-
bility. The fluorine retention was relatively high with soil, the
fluorine excretion in the urine low. The supplementary feeding
of the three fluorine-containing substances extending over 316
days brought  various high levels of fluorine depositions which
agreed with the quantities resorbed.

Experiments are described in which sheep, pregnant sows, and
weaned piglets were given fluorine orally in the form of an
aqueous  solution  of sodium fluoride. Histological investiga-
tions  were made and  all organs, especially the endocrine
glands, were investigated using usual methods and procedures.
The  fetuses  of  pigs and the  suckling piglets  showed  no
pathological changes in their developing teeth, in their bones
and endocrine glands. Weaned piglets showed varied changes
in teeth and bones according to the dose and duration of the
application of NaF.  Considerable weight reductions were ob-
served in  the thymus and adrenal glands of the test animals.
No changes were observed in the pregnant  sows. Sheep and
lambs showed the same changes in teeth and bone tissue as
were observed in the weaned piglets.

According  to experiments,  no  damages occurred  to bees
through dust and powdery substances containing fluorine. The
following toxicity  of dissolved fluorine compounds was found:
a) Sodium fluoride; lethal dose equals 20 micrograms F per
bee per 24 hours;  50% lethal  dose equals  11 micrograms F per
bee per 24 hours, b) Hydrofluoric  acid lethal dose equals 10
micrograms F per bee per 24 hours; 50% lethal dose equals 5
micrograms F per bee per 24 hours. There are different sen-
sitivities between  the strains of bees and there is a  repellent
effect of hydrofluoric acid depending oA its  concentration. In
57 samples of 100 normal bees each, average values between
0.63 to 4.81 micrograms F per bee were found. The bees came
from various  regions with and without fluorine emissions. In
the Rheinfelden emission area, only normal values of 0.6 to 2.8
micrograms F per bee were found in bees which were said to
have died from fluorine emissions. Test colonies at a distance
of 300 m from the plant showed no disorders after three years.
In the Seelze emission region limiting values from 0.9 to 10.6
micrograms F per bee were found in bees which were said to
be injured by fluorine emissions. Of two test colonies placed
at a  distance of 300 m from the plant, one died,  the other
developed badly during the three years of observation. In the
examination of bees which are suspect of fluorine intoxication,
other important  diseases  and aggravating  factors  must  be
recognized by differential diagnosis.

Spruce needles from a mountainous area were examined after
continual  subjection  to short periods of relatively high levels
of atmospheric sulfur dioxide contamination. The metabolism
of plants damaged to different degrees by flue gases was in-
vestigated to  determine reasons  for resistance based  on inter-
nal  structure. Paper chromatography was  used   for  car-
                        bohydrate analysis and tannifi content determined by titration
                        with potassium permanganate. pH analyses were made using
                        methods previously developed for needle analysis.  The first
                        sign of SO2 damage is a foster aging of the needles of less re-
                        sistant trees. Suprisingly, the level of active photosynthesis did
                        not  decrease significantly in the damaged needles, but the
                        faster aging process and resulting net loss of needles reduced
                        the total tree activity and material storage. In contrast to nee-
                        dles of resistant trees, those of damaged spruces have a lower
                        water  content,  a higher sugar level, a  lower  acidic  buffer
                        capacity, and a higher pH in their cell sap. This last  finding is
                        unexpected in light of the acidic nature of flue gas. The degree
                        of these effects shows a dependence  upon the  time of year.
                        Comparisons with other studies shows an apparent  influence
                        on the type of SO2 damage of the degree and length of expo-
                        sure to the pollutant flue gas.

                        The discovery  of  plasmodasmata in  the  outer   walls  of
                        epidermis cells of leaves raised the problem of the physiologi-
                        cal significance of the formations now known as ectodesmata.
                        Their localization in the outer  walls suggests they  could be
                        connections between the protoplasts and the epidermis cells or
                        the entire living plant and the outside world. They could serve
                        as stimulus transmitters or as a means of exchange of material
                        from the surface of the leaf into the cell or in  the opposite
                        direction. A series of experiments was initiated  to  try  to
                        establish the function  of the ectodesmata. The first results of
                        those experiments are presented and discussed, including the
                        occurrence and distribution  of  ectodesmata in the  leaves  of

                        methods, and relationships to the function of transport paths.
                        Evidence is submitted establishing  a  probability  that  the
                        exchange of material between the surface of the leaf and the
                        interior of the tissue takes place  through the ectodesmata of
                        the upper epidermis outer walls.

                        The effects of  cement furnace dusts on plants and  soil were

the soil reaction and nutrient. Under certain circumstances this
may lead to  impairment  of plant production. The dust sedi-
mented in the vicinity of  cement factories appears to have no
immediate danger for plants as long as its influence can be
counteracted  at the right  time. The best counteraction can be
achieved by  the application of physiologically acid  fertiliza-

In the area surrounding an iron ore roasting  plant, an experi-
ment was conducted  in  the  open countryside to determine
tolerance  limits  for rating sulfur dioxide  emissions and  as-
sessing their effect on vegetation. Investigations were con-
ducted on the relationship between SO2 content of the air and
its  damaging  effects  on  agricultural  and forestry  cultures.
Macroscopic  and  microscopic  observations  were made  to
determine acute  and chronic damage. Growth and yield obser-
vations were  also  made.  Kind and degree  of damage were
determined; characteristic damage pictures, and the time span
between  the  SO2 effect and  the appearance of  the  first
damage are listed. Sulfur dioxide emissions were measured
and  continually  registered by  an  ultragas-3-instrument.  The
final  values will be  given after all the experimental  results
have been obtained.

OCCURRENCE  OF  BARK-BREEDING FOREST PESTS IN

sociates, Denver, Colo.
Investigations were  conducted  to determine  the  extent  to
which forest  plantations, which have already been weakened
by  industrial  waste  gases, were exposed to  the  additional
danger of forest pests. The principal emitters in the areas stu-
died were power stations using  brown coal, generating large
amounts  of sulfur dioxide. Determinations of the insects were
made at the fall cutting of the trees according to the feed zone
characteristics or to the development stages. The frequency of
appearance was  determined by the number of tree trunks af-
flicted and by the breeding density of the afflicted trunks. The
most significant  pest occurring in the  pine was Pissodes  har-
cyniae. This pest frequency appears in such a large breeding
density per tree truck that the trees die during larva-formation.
The  frequent occurrence of Xyloterus  lineatus is  significant,
and it should be considered a technical pest. Hylurgops pal-
liatus,  Pityogenes  chalcographus,  Ips   typographus,  and
Dryocoetes hectographus  are considered  secondary  pests. It
was determined that the density of bark-breeders is higher in
highly-fume-damaged fringes  than in  areas  with less fume
damage.

Investigations were conducted on the special distribution of
S(35)  in spinach leaves after exposure to 50 ppm SO2 (35). For
experimentation with radioactive  gases, a device was con-
structed consisting of a Handschvhkammer and  a gas chro-
matograph. This device  permitted safe handling of the radioac-
tive gases. An electrophoretic method  for separating sulfites,
sulfates, and sulfurous  amino acids, and N-Ethylmaleinimide
compounds with amino acid containing sulfur is given.  The
SO2 was detected by gas  chromatography. The distribution of
S(35)  in the spinach leaf after exposure to SO2(35) was studied
microautoradiographically. After seven hours of exposure, a 2-
to 5-fold enrichment of S(35) in the guard cells  of the pore
openings  was  observed  with  respect  to   the remaining
epidermal cells.  A portion of the S(35) also entered the vascu-
lar paths. The chemical distribution of  S(35) was also studied.
The result was the rapid installation into cysteine, glutathione,
and unknown soluble and  insoluble sulfur compounds. The ox-
idation  of  sulfite to sulfate also occurred. The results are
discussed  with  respect  to the  mechanism of  the toxicity of
SO2. (Author summary modified)

Various crops and vegetables were exposed to sulfur dioxide,
nitrogen dioxide,  and chlorine in the  laboratory and in the
field.  The plants were afterwards exposed to varying degrees
of sunlight. Two series  of field  experiments were conducted:
one with dry plants, and one with plants which were sprinkled
with water. The plants  were exposed to concentrations of 10
ccm,  100  ccm,  and 1000  ccm/cu  m space for one hour ten
times in a row. Winter rape (Brassica napus oleracea) began to
show  injuries at gasification with 100 ccm/gas cu m. Nitrogen
dioxide  was slightly less injurious to this plant than S02 and
C12. Winter rye wheat,  barley and oat were highly sensitive to
the gases and showed injuries already at concentrations of 10
ccm. Sugar beet began to show injuries at concentrations of 30
ccm of  the three  gases. Sulfur dioxide and C12 attacked the
plant  more heavily at day  exposure and NO2 at night-time ex-
posure. For potatoes, the  toxic dose was between 30 and 100
ccm with NO2 and 10 to  30 ccm with C12 and SO2. Alfalfa,
lettuce and beans, too, were less sensitive to NO2 than to the
other  gases. Of the three  species, beans were most resistant.
Exposure to sunlight increased the effect of the gases on the
plants. Sprinkling at the time of exposure was of disadvantage
to the plants.

Several experiments were conducted to determine the effects
of mercury and mercury oxide on plants. When mint and bean
plants were placed next to a bottle of mercury, the leaves and
stems were  covered  with black spots on the third day, and
then turned completely black. A mint plant and mercury were
placed under a bell-glass whose sides were coated with sulfur.
The plant remained intact, indicating  that sulfur prevents  the
harmful effects of mercury.  No damage was observed when
the mercury was  covered with water. The experiments also
showed  that mercury is not harmful  unless  it is mixed with
water or soil, or is in  contact with the roots of the plants. Mer-
cury oxide killed a mint plant when placed in contact with the
roots. Beans planted in soil mixed with mercury oxide became
feeble and disfigured; beans  planted in a mixture of soil and
lead oxide continued to grow and were four times as strong as
those grown in soil and mercury oxide.

The effects of a coal gas pipeline leak on a tree lined  street
are discussed. The  withering originated in the root system, fol-
lowed by  the  death  of the bark along the base of the tree
trunks.  A damage center was  established,  and  the damage
decreased with increasing distance from the  center. Five trees
which were  totally destroyed stood next to or opposite each
other, so that the  center must be between them. This damage
center coincided with the position of a gas pipe which crossed
the five trees. In spite of hibernation, a few  weeks were suffi-
cient to destroy the root system of several trees. A sewer con-
struction project is assumed to be the cause  of the sudden gas
leak. It  is known  that coal gas is a plant poison, but little is
known about the component in question. The damaging  effect
during hibernation  indicates that this is not the result of plant
food intake, but of a penetration of the root system.

OBSERVATION  OF  COAL  GAS  DAMAGE  TO  FRUIT
TREES.   (Beobachtung  uber Gasschaden  an Obstbaumen).
Deut. Baumschule, vol. 3:10-12, 1951. Translated from the Ger-
man. Belov and Associates, Denver, Colo.
The effects of chlorine gases, resulting from coal combustion,
on  vegetables  and  fruit trees  are  discussed.  Damage  to
spinach, lettuce,  endives, rhubarb, onions, peas, and cau-
liflower was observed in all  cases. This damage resulted in a
discoloration of the  leaves  until  they were withered and
brown.  The vegetable plants recuperated  according  to  the
degree  of damage  especially  when  there  was  sufficient
moisture.  String  beans,  red  beans,  cabbage,  and  brussel
sprouts  were also heavily damaged during the fall of 19SO. It
was found that among the fruit trees the apple is the most sen-
sitive. The leaves began  to shrink, showed a dull pale green
discoloration, and  fell off within a short period of time. De-
pending on the degree of damage, loss of leaves was followed
by a loss of young fruits. Well growing pear species were less
damaged  than  the weaker   growing  species. Peaches and
apricots lost their leaves during the spring after a pale green
discoloration, and also lost some fruit. Among the berry-bear-
                         ing fruits, gooseberries lost leaves and fruit, currants showed
                         brown coloration of the leaves, and raspberries and blackber-
                         ries suffered no damage. These observations indicate that con-
                         siderable damage can be inflicted on cultured plants by indus-
                         trial waste gases.

                         Several years of research on the  fluorine content of plants in
                         non-industrial regions  have shown that the  natural fluorine
                         content may vary between 0.2 and 2.0 mg/100 g dry matter.

                         The Exoteleia dodecella L. is one of the most widely spread
                         forest parasites in Poland. These insects occur in large quanti-
                         ties in young pine cultures on poor soils and within regions of
                         industrial atmospheric pollution. The caterpillars of Exoteleia
                         dodecella L. feed sucessively on 2-3 needles during the late
                         summer and fall and after hibernation in spring. Full  grown
                         caterpillars insert themselves by feeding into the buds for their
                         subsequent pupation. Over areas where this  insect occurs in
                         large masses, all  buds  are destroyed  resulting in permanent
                         trunk deformations, growth inhibitions of the trees, and forma-
                         tion of dwarf shapes. Because of the damage  to large areas of
                         pine forests, Exoceleia dodecella L. is being combatted by
                         contact poisons. It is recommended that this  be done  in  the
                         spring when the caterpillars are  leaving the needles and
                         beginning to invade the buds. Best results are obtained with
                         emulsion-type contact poisons, such as 2% Foschlor 30,  2%
                         Tritox 30, and 5% Azotox M 25. Good results  are obtained by
                         using these  compounds,  which can penetrate the inhabited
                         needles and  buds and which have a long period of toxicity,
                         and by using the proper equipment.

                         necrotic spots distributed  across the entire leaf surface, or as

high concentrations. Edge and border damage occurs only at
low  concentrations,  which  are  different  for  the  individual
acidic gases, depending on their toxicity. This  localization of
damage requires transporting the gases toward  the leaf edges
and tip, and an effective suction at these  leaf  pans. The ex-
istence  of  such a suction effect, which  is significant with
respect to the problem of water and  substance distribution in
the  leaf,  was  made  probably  by  experiments  with  cut
branches,  allowing them  to  absorb  dilute HC1 and sodium
hydroxide  solutions  and chromium  fluorides.  The  results
showed that the preconditions for water and substance flow in
the leaf are  created by leaf pressure and evaporation, but that
the finer distribution in the leaf is regulated by the leaf itself.

The  role of immunobiological and contributory factors in the
development of bovine trichophytosis was investigated in a
two-part study. In the first part, black cattle hair from 124 nor-
mal  and diseased black-spotted lowland cattle  was analyzed
for iron, copper, manganese, and cobalt contents to determine
the effect of the trace  elements on the course of trichophyto-
sis. Cattle with high iron levels in their hair tended to be af-
fected  less  frequently  and to develop  milder symptoms at a
later date than animals with low iron values. In vitro  studies
were next conducted on the effects of iron and copper on the
growth  of the fungus  Trichophyton verrucosum,  the  most
frequent causative agent of bovine trichophytosis. Traces of
copper had  no influence on oxygen consumption, but increas-
ing concentrations (16-40 meg/ml) significantly stimulated fun-
gal growth. Concentrations of 240 meg/ml and higher caused a
statistically   significant   inhibition   in  the   growth   of
Trichophyton mentagrophytes. Similar results were obtained in
the studies  of the effects of iron on oxygen consumption of
the Trichophyton  mentagrophytes. Although iron stimulated
oxygen consumption in the first 72-96 hours of the experiment,
oxygen  consumption after 120 hours in media containing 50-
200 meg of iron/ml was equal to or lower than that of iron-free
controls. At levels above 300 meg, oxygen consumption was
distinctly lower than  in iron-free fungal suspensions.  It is con-
cluded that  these elements are activators  of fungal metabol-
ism, with  their fungistatic effects dependent on concentration
and, in the case of iron, on time.

The  concepts of absolutely pollution-resistant and fully indus-
try-proof woody  plants,  which appear especially in forestry
textbooks  and catalogs, are not true. Forestry is in a  worse
situation with respect to combatting pollution  in comparison
with agriculture. Continuous efforts are exerted to achieve the
highest  standards  of  soil fermentation. However,  optimum
nutrition is not always achieved. Examples of Pinus griffithi,
Pinus silvestris,  Abies concolor, Picea emorika, all  leaved
trees and confiers, Plantanus acerifolia, Picea oungens, and
Juniperus  chinensis   pfitzeriana  show  which   combined
agrochemical and soil problems acquire primary importance in
the process of damage assessment. Frequently, conifers  are
more resistant than leaved trees to emission damage, espe-
cially in conditions of intensified fertilizations along with stan-
dard  liming  or  application  of individual  fertilizers  in  ac-
cordance with orographic data and imitation action. With con-
siderations such as type and origin of the plant, together with
the type of emission and  the use of impact fertilization, emis-
sion damage is greatly reduced and sometimes even complete-
ly eliminated. This  phenomenon was discussed, along with the
effects of nitric and phosphoric acid and lime fertilization. It
was shown why no general formulas exist for calculating emis-
sion damage  possibilities  and why rigid chemical and  mathe-
matical  determination  systems must  be  described  as un-
realistic. It was concluded that more trees and more forests in
the  vicinity  of  industrial centers  and  housing  estates  are
needed. A mixed  forest  appears to be the most important
producer of oxygen and  most efficient filter of waste gases,
smoke, and dusts. (Author abstract modified)

A brief historical review  of smoke damage to forestry  caused
by several large factories  in Upper Austria and measures being
currently taken are given. Spruce, fir, and pine are particularly
sensitive to smoke. The area in which the forests are attacked
by smoke amounts  to about 1,850 ha in Upper Austria. A com-
pensation chart was constructed according to  the degree  of
damage. The  losses were assessed empirically in terms of the
growth increment from results of research conducted  by ex-
perts from factories causing the smoke damage on a scientific
basis. As  a result, the heavy attacks  of sulfur dioxide were
reduced in 1965  to about one third  of the value of previous
years. Deciduous trees were planted;  attention was given  to
the cultivation of spruces and  white pines that will be com-
paratively resistant to  exhaust gases  from industrial  plants.
The grafting technique was adopted; various mineral fertilizers
were used. The costs  pertaining to the conversion of stands,
means of protection against  gnawing by wildlife, maintaining
of the cultures,  and measures  against the  bark-boring beetle
were fully covered  by the factories.

AIR POLLUTION  TRANSLATIONS
Experiments were conducted to test the inhibitory effects of
certain constituents of power plant dusts on the metabolism of
plants. Dust samples provided a total spectrum of the sizes of
dust particles. Feeding cabbage was used as the model plant
because of its comparatively intensive photosynthetic activity.
Germination was realized in Petri dishes located in a thermo-
stat at the temperature of 20 C  and exposed to illumination of
700 lux. Illumination lasted for 8 hrs and occurred  every 24
hrs. The water layer in the  individual dishes was high enough
to cover the seeds without blocking sufficient air access. Acid
flue dust (pH 4.3) significantly  inhibited both germination and
growth.  Less acid flue dust (pH 5.3)  had no influence, and
neutral flue dust (pH 6.4)  exerted  a positive effect Results
showed that dusting of the upper side of the leaf exerts more
influence on the inhibition of photosynthesis than dusting on
the lower side of the leaf. This is mostly  due to the fact that
more  flue dust will adhere to the  upper side,  and  both  the
choking of vents and the light screening from  the flue dust
layer  will be evidenced on the surface of  the leaf. Results
showed that the soluble component of flue  dust also inhibits
photosynthesis. Flue dust made wet by water mist is a less ac-
tive inhibitor of photosynthesis. In  a microscopic comparison
of dry and wet flue dust, accumulation of dust particles occurs
which evidently leads to some dechoking of certain vents, and

PRELIMINARY RESULTS OF  ECONOMIC  AND SYLVICUL-

Results of  research  and sylvicultural and economic measures
taken to reduce the harmful effects of emissions in the area of
Ziar N.Hronom were summarized. The source of the emissions
was a metallurgical  plant producing aluminum.  The sylvicul-
tural measures were first directed toward the most severely at-
tacked zone I of the area, and on non-sylvan areas, which
were  not used to grow trees, located within the reach of the
maximum smoke attack between the forest boundary and the
plant. In  zone I, practically all degrees of injury were found,
starting  with depigmentation  and necrosis  formation in  as-
similation  organs, up  to the  loss  of foliage  and decay of
conifers.  From among four-year plants on unforested land,
which were subjected  to various cultivation operations includ-
ing mineral  fertilization, best results were obtained for black
alder, birch, red oak, pedunculate oak, and Austrian pine. Fer-
tilization  with lime and ground Thomas slag proved efficient
only in the case of black  alder. A much better result was pro-
vided by hoeing and mowing. Successful foresting depends not
only on exposure to the emitting source,  but also on a lower
HF concentration. Terrian  relief creates  a  natural barrier to
penetrating emissions. The beech stand, situated 2110 m east-
ward of the emitting source, reduced the detrimental effect of
HF in its above surface layer by approximately 30% in com-
parison to a free area in front of the stand boundary. A ten-
year pine culture,  1950 m  south-southeast  from the source,
reduced the harmful effect of  HF  by approximately 50% by
comparison  to total  clearing, and thus fulfilled the protective
function by being in front of the sheltered trees.

                         A method is developed mathematically  to express dynamic
                         long-term injury to whole groves as  trees, as  opposed to
                         present static methods of describing injuries  to organs of in-
                         dividual trees. Injuries to groves by gaseous emissions can be
                         characterized, according to this  method, by rate of injury,
                         derived  from the relationship between  performed (random)
                         processing of tree reserves  and the processing  prescription
                         (permissible processing). Results can eventually  indicate the
                         percent  of reduced  growth increment, and, to some degree,
                         the future course of injury. The method was verified by appli-
                         cation to the forest farm Janov, located in Krusne  hory. It was
                         found that random processing of spruce trees had greatly ex-
                         ceeded  permissible   processing;   the  structure  of random
                         processing shows a  continuing increase in the proportion of
                         processed dry woods. Injury to the grove has  reached the
                         point where die existence of  the entire forest in the region of
                         the Krusne hory ridge is threatened, and because of increasing
                         industrial emissions, is likely to increase. Results  from this

                         lated with findings  of investigators using other  approaches.

severe damage than trees kept in darkness. However, the dif-
ference was  not  as  pronounced as that recorded for  sulfur
dioxide damage and was confined to a narrowly limited range
of concentrations. Darkness did not protect trees against in-
creased NH3 concentrations as it does against high SO2 con-
centrations.  Among the six tree species tested,  ash  was the
most  susceptible  to NH3  damage and  oak, maple, and sitca
spruce the least susceptible. Intermediate positions were occu-
pied by beech and rose trees. This  classification of trees ac-
cording to their resistance coincides with the results of tests
for the effects of SO2. As confirmed  by the tests  with  to-
matoes and  flowers, NH3 damage is  characterized by the
decomposition of chlorophyll and the precipitation of  tannin
and is thus confined to  green leaves. The crown leaves of
flowers and tomato blossoms were not damaged by exposure.

THE GROWTH OF POTATO SPROUTS.  (Uber den Einfluss

The growth of potato sprouts under the influence of a labora-
tory atmosphere   in  which coal gas  was present  was  in-
vestigated. When  a potato shoot approximately 7 cm high and
several smaller shoots which  were grown in  a greenhouse
under a bell jar, were placed in a laboratory room, the shoots
twisted from a vertical to a horizontal direction. If  potatoes
were brought into the laboratory and covered with a layer of
water, they  continued to  grow in a vertical direction. It was
confirmed that the  twisting of the shoots  was no due to
heliotropism, humidity, or hydrotropism; the  reason for the
twisting was the  effect of the  impure  laboratory atmosphere
which  contained coal gas.  A coal gas concentration of 0.1% in-
duces twisting and thickening in the  potato sprouts. If the con-
centration is reduced to 0.002%, no twisting of the main  sprout
is produced.

THE  ABSORPTION OF  SULPHUR DIOXIDE BY SPRUCE
AND PINE TREES. (Naturwissenschaften (Berlin), 50(11):407,
1963.  1 ref. Translated from German.  Belov and Associates,

During an investigation of the composition of spruce and pine
needles in stands  damaged by smoke, the sulfur content of the
needles increased in  the winter. Part of this accumulation can
be explained by the weight loss that occurs in winter and the
relative accumulation of the content material that this causes;
in heavily damaged trees the increase  is so large that this ex-
plantaion  is  insufficient.  Investigations were  conducted to
determine if sulfur dioxide was  assimilated by the needles dur-
ing winter. Marked sulfur  dioxide, SO2(35), was  used for this
purpose. In  15 to 25 year old, healthy, free-standing spruce
and pine  trees, a well developed branch was wrapped in a
polyethylene  bag. An ampule of SO2 was crushed in the bag
producing a concentration  of 8-10 mg SO2/cu m of air. Needle
samples were taken after 24 hours and at regular intervals. The
results showed that the needles  of the treated branch absorbed
almost the entire  quantity  of SO2. A small amount of the sul-
fur was transported to ungassed needles in other parts of the
crown,  but  it was intensively  stored  in  needles of  newly
formed shoots. Similar experiments showed that SO2 is also
absorbed at night.

Investigations  were conducted  to determine if nitrous gas,
hydrochloric acid, and ammonia cause plant damage similar to
that caused by  sulfur dioxide, and to determine the participa-
tion of the iron contained in  chloroplasts  in  this disease
process. The assimilation apparatus in  the moss fontinalis was
primarily  affected  by  nitrous  gas and these  effects  cor-
responded to the effect of SO2; HC1 had a lesser effect, and
ammonia was not considered  to be an  assimilation poison.
Clover, tobacco, and spinach  plants exposed to nitrous  gas
became withered and bleached with inhibited assimilation after
exposure to light. Plant damage by SO2 and nitrous gas con-
sists of a fixation of iron followed by a photooxidative poison-
ing of the protoplasm by chlorophyll. Tests on com were con-
ducted to determine if the water soluble part of iron increases
after introducing assimilation  poisons.  Pre-  treatment with
fuming nitric acid resulted in a water soluble iron content four
times higher than normal. The effect of smoke gases on plants
consists of a direct cancellation  of the catalytic activity of the
iron in the chloroplasts. The photooxidative poisoning of  the
protoplasm is considered to be a secondary effect.

The effects of mercury vapor  on  plants were  investigated.
When a mercury-filled capsule  was  placed on each side of a
petunia stem, the leaves turned  black, withered, and were
hanging. Another petunia, enclosed under a dish-cover where
there was no mercury, retained all its vigor.  Experiments were
also conducted on mint plants. On  the inner surface of one
dish-cover sulfur was placed on the flower. In the other dish
cover there  was no sulfur. In  less than 52 hours, the mint
leaves in the dish containing only mercury had been complete-
ly destroyed. The leaves of the  plant in the dish also contain-
ing sulfur were not affected.  It was concluded  that mercury
vapor  has  a damaging  effect  on vegetation,  and  that  the
presence of sulfur counteracts this effect.

The question of whether mineral substances other than sulfur,
silicic acid, and iron accumulate in the assimilating organs of
smoke injured  plants, particularly cations  such as calcium,
potassium, and  magnesium is analyzed. Since analyses of in-
jured needles alone cannot provide definite  results, gassing
tests with older spruces were  performed. Two twigs were
packed into  polyethylene bags;  one was  gassed with air  and

sulfur  dioxide,  the other with pure air. Not only did the
gassing increase the sulfur content, but also that of Ca and
Mg; it caused a considerable increase of water soluble mag-
nesium. A second  gassing experiment was performed, which
yielded no difference in the concentrations of Ca and Mg, but
a markedly higher potassium content was found.

Apsheron Peninsula discharge a great amount  of wastes, par-
ticularly  carbon monoxide,  sulfur dioxide,  fluorine  com-
pounds, hydrocarbon vapors, chlorine, and hydrogen sulfide.
In most cases, these compounds adversely affect green plants
which function,  at times, as protection against  gas and smoke.
When the air  is  polluted by irritant gases dark brown burns ap-
pear on the leaves. Partly withered and some yellowed leaves
are  also  found.  The toxic action of these pollutants also  af-
fects the root system. Trees which exhibit gas resistance in-
clude  elm, maple,  pistachio,  oleaster, almond,  honeysuckle,
and others. The establishment and development of green trees
are  important as a  means of combatting air pollution and for
the sanitary well-being of the industrial areas.  Several recom-
mendations for  establishing green plantings in  industrial areas
are included.

Tomato plants placed in a lighted chamber to which  2-5 ml of

the  end of 30 min; 13 microgram/cu m at the end of 45 min;
and traces of H2S  at the end of 60 min.  The release appeared
to be  conditioned  by light, since plants treated in the dark
produced no emission. Though some of the H2S was traced to
the  sulfur content of the plants, the greater portion originated
in the reduction of  atmospheric SO2 by the plants.

                        The effects of atmospheric fluorine compounds, such as are
                        emitted from aluminum industries, on various leafy plants are
                        investigated. Tomato, bean, and  tobacco  plants were grown
                        under controlled conditions and subjected to varying hydrogen
                        fluoride  concentrations  and different  atmospheric  conditons.
                        The rate of absorption of atmospheric fluorine is clearly pro-
                        portional to the concentration, time of exposure, and relative
                        humidity. The fluorine is accumulated near the edges of the
                        leaves and results in necroses in that area. The level of toxici-
                        ty varies from plant to plant. It can be attained from a heavy
                        concentration of short duration, or more probably from  a
                        semi-permanent pollution of low concentration. The difference
                        between fluorine and sulfur dioxide absorption is explained.

                        Observations made over a period of 15  years on the relative
                        sensitivity  of various plants  to fluorine compounds are re-
                        ported. The three methods used in evaluating damage to plants
                        are: observation of typical necroses appearing on the foliage,
                        chemical analyses of the fluorine  content of the plants,  and
                        utilization of certain indicator species to detect fluorine.  Ex-
                        aminations of tree leaves permit the establishment of sensitivi-
                        ty limits. No injury occurs below  25 ppm, variable reactions
                        occur from 25-105 ppm, depending on the climate and health
                        of the plants, and burns are  almost always present from 105
                        ppm  on. Plant  species are separated into  4 classes based on
                        their sensitivity. The most sensitive plants can be used as in-
                        dicators  of the presence of  fluorine, both  in  terms of the
                        degree of  contamination and the limits of the contaminated
                        zone.

                        Turnips, barley, and trees growing on farms bordering a fertil-
                        izer  manufacturing plant and a refinery  exhibited  disturbed
                        growth, partial defoliation, and leaf discoloration. When sulfur
                        dioxide emissions in the area were determined to be of a mag-
                        nitude sufficient to cause plant damage,  the question of emis-
                        sion  effect on the fertility of soil was clarified in correspond-
                        ing   soil  investigations.  Soil analyses   revealed!  a 30-50%
                        decrease in  'root soluble' nutrients,  significantly  lower pH
                        values, and a decreased base activity that correlated with an
                        abnormally high sulfate content in the soil as well as in spring
                        water and rivers. These results show that the acidifying action
                        of sulfur dioxide can have an adverse influence on the alkaline
                        balance of light soil.

The  effects   of  various pollutants  on  farm  animals  are
discussed. The emissions from such sources as power plants,
metal processing, cement works, chemical industries, fertiliz-
ing, and  nuclear installations are described. The effects of the
various pollutants  can vary, depending upon such factors as
concentration, climate, age of animals, health of animals, and
individual sensitivity. Inhalation  of ashes, cinders,  or  other
light  particulates  causes  irritation  and  inhibits  important
digestive  processes.  Sulfur  dioxide  irritates  mucous  mem-
branes and  disrupts metabolic processes. The symptoms of
acute and  chronic  arsenic poisoning  are discussed. A  con-
siderable degree of toxicity for  cattle  is noticed  from power
plant ashes. Bees show a marked effect from exposure to ar-
senic compounds. Typical symptoms of fluorosis  in cattle are
dental  changes. Synergistic  effects  of pollutants  are  men-
tioned. The general air quality of Czechoslovakia is discussed,
and  current  legislation, including  air quality standards, is
described. An estimation of economic damages  due to air pol-
lution is given.

Research involving the development of sulfur dioxide-resistant
coniferous trees is  described.  The larch tree was selected for
breeding, since it  looses its needles in the  winter, similar to
deciduous trees, which are more resistant to SO2. Two year
old larches  developed from  directed  cross-pollination,  partly
from  European larches  and  partly from the Japanese  larch,
were  exposed in  a  controlled  atmosphere greenhouse  for
periods of 10 to 50  hours to SO2 concentrations of 0.34 to 0.73
ppm. Damage evaluation was standardized by a needle-damage
scale  of  1-10. On  the  average,  all hybrid  trees exhibited  a
greater resistance  to  SO2 than  the pure trees. Hybrids from
two different strains  of Japanese larch had significantly  dif-
ferent  responses.  The  degree of resistance  of  the various
breeds is based mostly  on genetics.   This indicates that the
development of a resistant strain from  direct cross- pollination
is a promising possibility.

FLUORINE  ABSORPTION   THROUGH THE  BARK  OF
SHOOTS AND ITS EFFECTS.   Angew. Botan.,  vol. 19:172-
181, 1937. Translated from German. lOp.
The effects of fluorine absorption on the shoots of plants and
trees are investigated. The primary goal of the research is to
determine whether the fluorine  compounds which penetrate
the bark  of  the shoots  in an earlier season  can affect  the
spring  growth of  the  plant  and/or  effectively  disturb  the
identification  of fluorine  fume  damage  on  spring  growth.
Shoots accumulate  fluorine-containing waste gases more or
less in their barks, as much a result of exposure in winter as in
summer. They are also capable of, but seldom do, store up ac-
cumulations in the xylum in water soluble and insoluble forms.
The  blossoming of  branches and the further development of
new  growth are not noticeably injured by the fluorine  com-
pounds which are stored in the  bark. All new outgrowths of
fluorine-containing branches remain free of fluorine in a fume-
free  atmosphere. Proven fluorine content in spring growth is
regularly a proof of a new fluorine fume effect during or after
the blossoming.

A study of damage to spruce trees  due to air pollution is
presented. About 900 trees were studied and grouped into re-
sistance  classes according to their  phenotypical smoke  re-
sistance. Relationships between  age, quality of  growth site,
degree of needle coverage, and weather conditions were deter-
mined. Trees  in  different classes exhibited different  growth
patterns, due to different physiological activities  of the trees.
Trees sensitive to damage had higher concentrations of sulfur
in their needles, due  to a higher degree of sulfur dioxide in-
take. Intensive  studies of the  needles  indicate differences
between  sensitive and non-sensitive spruces in terms of water
circulation, glycides, amino acids, and potassium  levels. These
results can be practically utilized in forestry by providing  valu-
able help in cultivating forest trees which are smoke resistant.

PARTIAL RESULTS  OF RESEARCH IN THE SMOKE RE-
GION OF THE KRUSNE HORY MOUNTAIN RANGE. (Nek
tere  vysledky  vyzkuma  v  krusnohorske  kourove  oblasti).
Translated from Czech. Belov  and Associates, Denver, Colo.,
19p., Jan. 20, 1970.
Following the rapid  advance of damage by smoke emissions to
forest flora in the eastern section of the  Krusne  Hory moun-
tain  range,  sulfur dioxide measurements were  taken in  the
most affected areas.  Where sulfur dioxide  was  present,  the
average concentration was one mg per cu m of air. The in-
fluence of precipitation on this concentration is considerable,
as is that of fog and, to a lesser extent, wind direction. The
measured concentrations are high enough to cause a decrease
in production and damage to  plant life.  They correspond to
calculated and measured values of the sulfur content in the as-
similative organs of injured plants. Further research indicated
that  fertilizers will  increase the  resistance of assimilative or-
gans of the plants  and promote new growth, even  in  trees
highly sensitive to SO2. Related investigations pertained to the
possibility of using  forest flora, especially spruce, to indicate
the  action of  smoke gases  and their  presence in  the  at-
mosphere and to the  significance of  forest flora for cleaning
air in industrial regions. Based on measurements of sulfur in
needles and the turbidity of  water extracts of needles,  it is
concluded that spruce trees are suitable for proving the in-
fluence, and its extent, of smoke emissions. Forest flora are
shown to have only a negligible role in  air purification  near
large enterprises. On the other hand, their ability to absorb
sulfur dioxide is great enough for them to have a prominent

Of the fruit trees in the  neighborhood of a brickyard, the ap-
ples and cherries were undamaged, while in contrast the dam-
son plums, yellow plums, and yellow Victoria plums showed
damage on foliage and fruit Damage symptoms of the dam-
som plums were necrotic spots of tissue that appeared either
as sunken patches about fingernail size or,  in cases of greater
extend, as an apical zone of retarded growth. The diseased tis-
sue was coffee brown in color, and beads of sap frequently
could  be found around the border of the necrotic zone. Micro-
scopic examinations revealed that the epiderma cells  were
filled  with brown  granular  masses  instead  of dark blue
anthozyan. The pericarpal tissue, which in a healthy condition
exhibits vesicular, almost empty appearing cells with trans-
parent walls,  was small-celled, with brown colored cell walls
covered with brown granular concretions. Limitation of the
damage to the end  of the fruit is explained by the fact that
here the rain  drops hold  on  longest and the gases dissolved in
the water have  their  strongest influence.  The cause of the
smoke damage is attributed to hydrofluoric acid.

The  sources  of  sulfur  dioxide and  fluorine pollutants are
described  and the damage  caused to plants by these com-
pounds are related. Sulfur dioxide penetrates to the interior of
plants through the  stoma; therefor every  condition  favoring
the opening of the stoma also increases the  assimilation of
SO2.  The caustic action  of  SO2 is due to its reducing action,
which can affect plant metabolism. Sensitivity to SO2 depends
on  such  factors  as age,  nutritive  state,  and individual
tolerances.  Relationships between pollutant concentration and
time of exposure are a determining factor in threshold limita-
tions.  A distinction between plant injury and damage is made.
Various attempts to observe and control atmospheric pollution
are described. Fluorine compounds are among the most toxic
of pollutants. Fluorine  accumulation in soils and plants  is
discussed. The effects of fluorine on various types of plants
are noted. Synergistic action can occur when certain elements
introduced by fertilizers  react with fluorine compounds found
in the atmosphere.  Most  plants  seem  to have  a fluorine
threshold beyond which photosynthetic processes can be in-
visibly damaged.  Certain plants, due to their highly  sensitive
nature, can act as indicators of atmospheric pollution. Recent
experiments involving the effects of fluorine on fruit trees are
described.

                        Until 1940, 2 ppm of sulfur dioxide in the air was supposed to
                        be the  maximum acceptable  concentration for long  duration
                        pollution. Recent experiments  in the field in various areas
                        have shown that the limit has to be reduced to 0.02 ppm and
                        for HF it must be  considerably lower. It is better to charac-
                        terize air pollution by the frequency and duration of the times
                        a  certain critical concentration is exceeded, rather  than by
                        average concentration. The resistance of plants varies with the
                        type of emission, conditions -.if growth, phase of development,
                        and exposure. A distinction must be made between experimen-
                        tal resistance gauged by leaf  sensitivity and resistance in the
                        field  measured by yield and endurance. A generally  valid
                        sequence of potential damage  areas for plants cannot be made,
                        but a scheme for their classification into three groups  is given.
                        In order of generally  increasing  sensitivity, plants can be
                        grouped in the following manner: agricultural crops, decidous
                        forests, gardens and fruit plants, fodder crops, and coniferous
                        forests. This investigation into the sensitivity of plants to air
                        pollution  and the differences in their resistance to various
                        types of pollutants has revealed  that this can be  counted
                        among the most complicated problems of biology.  Neverthe-
                        less, the illusion is widespread that this matter may be judged
                        casually and simply. Only  by recognizing the severity of the
                        problem can progress be made. (Author summary modified)

                        Waste gases containing fluorine  and sulfurous acid are re-
                        ported to damage plants and  bees. Branches of fruit  trees af-
                        flicted by fluorine had leaves which showed numerous spots,
                        intercostal  discolored  stripes, or  also  withered  tips  and
                        periphrasis. All  which  remained,  in  some  cases, were the
                        blackish brown withered remains  of the leaves.  At a location
                        in central Germany, the bees  of a migrating stand died without

                        the wind had changed in their direction.  An investigation for
                        sulfurous acid in 36 plant samples resulted in various causes,
                        from manufacturing plant flue gases to gas remnants coming

siderable amount of flue gases containing sulfurous acid. This
was  especially  evident  along  the  southwest  slopes  of the
Haeusel Mountains which are relatively heavily exposed to the
flue gases coming from a paper mill in Hinterburg. Absence of
oak  mildew and  similarly the absence of lichen in  forests
which also contain oaks can be taken  as an indicator  for the
assumption that the region concerned  is strongly exposed to
flue gases. If one considers the usual  control  of the genuine
mildew fungus by means of pulverized  sulfa, which tranforms
under the influence of the atmosphere  into sulfurous acid and
thus  becomes fungicidal,  the  above  observed phenomenon
becomes quite understandable.

and Associates, Denver,  Colo., lip., July 2, 1970.
In one of the largest pine regions in the German Democratic
Republic damaged by industrial air pollution, the Duebemar
Heide, changes in the soil nematode population were studied.
By the action of sulfur dioxide, the density of the tree stands
decreased  considerably  and   a  rich  ground   vegetation
developed. Great amounts of dust containing high quantities of
lime  have changed the pH value of the humus cover from 3.7
up to 7. The total population density of the nematodes  showed
a significant reduction and an  alteration of the species  com-
position in the areas influenced by smoke. As a consequence
of a  more intensive microbial activity and a higher pH value,
the percentage of semisaprophage, saprophage, and predatory
nematodes increased considerably. In  the  undamaged areas,
however, on the semiparasitic nematodes which feed on  fungi
and roots showed a high population density. The extreme raw
humus conditions there  seem to be very favorable for them.

Experiments to  determine to what extent the resistance to flue
gas can be determined by environmental factors and heredity
are described. In addition, the limits  of gas concentrations
within  which young trees can survive and thrive are deter-
mined. The environmental factors  studied include  nutrition,
water supply, relative humidity, and others. Varying concen-
trations of  sulfur  dioxide and  hydrogen fluoride are ad-
ministered under controlled conditions to determine resistance.
Damage increases with increasing humidity and light intensity.
An optimum supply of nutrients increases resistance. For  SO2,
the first damage symptoms occurred after a ten day exposure
to 0.5 mg/cu m; at 2.0  mg/cu m  all assimilation organs are
destroyed. For  HF, the first  damage  symptoms occurred at
0.025 mg/cu m; total damage occurred at 0.25 mg/cu m. The
resistance of oak and  poplar is much greater than spruce,
larch, or fir. Also, the grafts of the resistant strains are more
resistant, indicating heredity as a cause  of resistance.

 Fumigation of plants at different hours  of  the day reveals
 distinct diurnal changes in sulfur accumulation which exhibits
 a certain relation to intensity of photosynthesis, but does not
 coincide  with  the   degree   of  leaf  sensitivity.  Apparent
 photosynthesis and sulfur accumulation reach their maxima in
 the late morning hours while leaf injury is most intense in the
 early morning hours.  The decrease  in leaf sensitivity during
 the light period seems to be associated with, among others, the
 formation of assimilates; further possible causes are discussed.
 Sulfur is also  accumulated during the night hours, which may
 amount to about one-third of the highest daily  values. Sulfur
 content of  unfumigated plants  also  shows a distinct diurnal
 variation. These diurnal variations result from changes in dry
 substance. Level of sulfur accumulation  varies considerably
 with  the  stage  of plante  growth. Degree of leaf  injury on
 plants of different age does not show a distinct dependence
 upon the quantity of accumulated sulfur. Sulfur absorption by
 leaves of the  same age decreased with increasing plant age.
 Fully developed leaves having the greatest photosynthetic gas
 exchange also had the greatest sulfur accumulation. The rela-
 tionships  in the degree of  injury of different aged leaves
 change in  respect to  each other with level of  concentration.
 Under exposure conditions of low concentration but of suffi-
 cient length to result in injury, older  leaves are,  in general, in-
 jured before younger  ones. With increasing concentration, ef-
 fects shift over to the younger leaves until finally, at high con-
 centrations, the degree of injury on just fully developed leaves
 correlates with sulfur  accumulation and apparent photosynthe-
 sis. Conifers also show distinct, age dependent  differences in
 sulfur dioxide uptake  and  in the degree of injury. The youn-
 gest needles absorb the most sulfur dioxide. Sulfur dioxide ab-
 sorption and also degree of injury increases with increasing
 growth of the new shoot,  while the  preceding year's needles
 show an inverse tendency. Dissimilar sulfur dioxide exposures
} may  shift the natural relations  in sulfur content. Long  lived
 crops show an increase SO2  content with leaf age while older
 leaves on short lived plants often have a lower  sulfur content
 than  younger  ones. Strictly  comparable samples have to be
 taken when proving sulfur dioxide  effects with the help  of
 chemical leaf analysis. (Author summary modified)

AIR POLLUTION TRANSLATIONS
The sulfur content of necrotic portions of a leaf and those por-
tions that are still green is determined by the past history of
ambient sulfur dioxide concentrations. When an ambient level
which causes acute injury is followed by a longer period of no
sulfur dioxide or of only insignificant concentrations, then, the
sulfur content of those parts still functioning may decrease
below that of the necrotic portions. In practice, however, sul-
fur content of the green leaf portions is generally higher. Great
differences in the sulfur content of injured and uninjured parts
of the leaf probably  result from sulfur dioxide effects and,
therefore, are a reason why a separate chemical analysis for
sulfur may be advantageous. If no separation is made, only
leaves having a  small proportion of  necrosis should be sam-
pled for (chemical) analysis because these reflect the level of
sulfur dioxide pollution better than do severely injured leaves.
In addition to the level of sulfur dioxide exposure, sulfur con-
tent of plants depends substantially on the duration of pollu-
tion-free periods. A single sample taken from vigorously grow-
ing, intermittently exposed plants is capable of reflecting only
a casual  situation. The danger  of misinterpretations  can be
reduced by repeated  sampling in the  course of the vegetation
period. The present results of investigations in both field and
fumigation experiments concerning a quantitative relationship
between sulfur content in plants and sulfur dioxide content of
the air with attention to inner  and  exterior growth factors,
make  possible an evaluation  of the chemical analysis  of the
leaf as proof of sulfur dioxide effects. The analysis, along with
attention  to precisely  described presuppositions, is a valuable
procedure for identifying sulfur dioxide pollution, also in areas
with concentrations causing acute  injury. The  causes  for op-
posing concepts about the diagnostic value of  the analysis of
plants could be clarified. (Author summary)

Studies made of the vineyards and apricot orchards in the cen-
tral part of the Valais district of Switzerland, an area exposed
to atmospheric  pollution from aluminum foundries and fertil-
izer plants show  that the causticity of emitted fluorides and
the fluorine content of the leaves depend closely on the kind
of mineral fertilizer used on the plants. Just how this interac-
tion works is still not  known but three possible hypotheses are
possible to explain the interrelationship: presence of chlorides,
presence  of boron and, finally, an unidentified  substance, par-
ticular to  certai phospho-potassium fertilizers. The effect of
the fluoride pollutio is made significantly worse by the almost
linear diffusion created by the winds of this alpine valley.

                         that while the absorption of  SO2 at high concentrations was
                         relatively small, sulfur accumulation in plants increased with
                         decreasing  SO2 concentration and  with increasing exposure
                         time. The old assumption that sulfur content in plants was an
                         indication of only chronic SO2 emissions but not of acutely
                         damaging SO2 concentrations was disproved. Under  practical
                         conditions, high concentrations do  not occur by themselves
                         but always together with low concentrations. In uniform plant

                         analysis is a reliable indicator of SO2 emission levels  at which

                         ble. In  discontinuous exposure to SO2, sulfur accumulation
                         first increases with the number of exposures and their duration
                         and then levels off. Photosynthetic measurements  disclosed
                         that the recovery during emission-free periods affected SO2

                         The use of indicator plants  for detecting air pollutants and
                         their range of distribution is gaining ground as a supplement to
                         physical and chemical analyses of air. Plant reactions con-
                         sidered to constitute proof of pollution include the amount of
                         pollutant accumulated and visible symptoms such as necrosis
                         or the presence of certain kinds of lichen. It also seems likely
                         that products produced by metabolic responses of a plant to
                         absorbed pollutants  are useful indicators. Combining  these in-
                         dicators with the specific sensitivity of individual plants or
                         species could lead to manifold possibilities. Trials in  progress
                         involve the use of indicator chambers, which  have an ad-
                         vantage over field indicators in that no damaging substances
                         are absorbed through  soil. Using  combinations of  indicator
                         plants should permit identification of pollutants responsible for
                         damage, even  when several pollutants  are  simultaneously
                         present, as in most industrial areas. A list is  included of in-
                         dicator plants suitable for sulfur dioxide, hydrogen  fluoride,
                         gaseous and stable inorganic fluoride compounds, and ozone.

roots. Immediately after treatment, 98% of the absorbed sulfur
was in the form of sulfates. At the end of 15 days, 92.5% was
in the form  of sulfates, 2.5% in the form of sulfurated amino
acids, and 5% in the form of sulfurated proteins. These results
show that SO2 is  metabolized by  plants  and excludes  the
hypothesis of plant poisoning by  cumulative SO2 action. To-
matoes  and  other plants growing in a SO2 atmosphere also
gave off hydrogen sulfide. The discharge came mainly from at-
mospheric SO2 but partly from sulfur in the plant. Unlike the
absorption of SO2, the release of H2S depended on light. The
absence of damages when pollution by S02 occurs in the dark
and the discharge of H2S  only  when plants are illuminated
open new possibilities for studying the metabolism of sulfur in
relation to atmospheric pollution by SO2.

A series of  experiments designed to determine the effect of
reduced oxygen or increased carbon  monoxide on plant growth
is described. The  results of the experiments indicate that gase-
ous impurities in  the atmosphere may have significant effects
on the rate  of plant growth. Another series of experiments is
conducted to determine the specific effects of coal gas, par-
ticularly  acetylene  and ethylene, on the growth  of  certain
vegetables. The results indicate that coal gas has an inhibiting
effect on  the growth in length and that it promotes the growth
in thickness. A  simple gas absorption system utilizing charcoal
decreases the  influence of  coal gas. The shortening and
thickening of affected plants is proportional to the amount of
coal gas  and to  the  duration  of exposure. The  effects  of
reduced oxygen partial pressure and plant respiration on plant
growth include nutations of 130-270 deg. Mercury vapor  can
produce similar differences in growth as coal gas, however, it
kills the plants within  a short time.

Studies were conducted of the  water balance of the Senator
variety of Pisum sativum in the presence of fluor (in the form
of sodium fluoride) in the substrate. The effect of fluor was
seen in a withering of those portions of the plant above the
soil. The  unfavorable hydration condition  observed is  the
result of changes  in the amount  of  water assimilated and the
amount given off. The presence of  fluor first stimulated and
then reduced the  amount of water given off. No preliminary
increase was noted before the amount of water taken in was
reduced, and plants assimilated no  water after 68 hrs in  the
presence of  0.29 and 0.25 g/1 F. A balance between the amount
of water taken in  and given off was reached only after approx-
imately 27 hrs at  a level of approximately 40% of the original
transpiration and approximately 90% of the original water con-
tent of the plant.

parts of  plants increased with  increasing  closeness to well-
travelled  highways  and  streets.  Even  in  the  vicinity of
highways, no increase was  noted in  lead  concentrations  in
below-ground and inner portions of plants. The lead content of
feed plants growing along roads was far  in excess of the sug-
gested tolerable concentration of 10 ppm.  For the protection of
humans and cattle, cultivation of food and forage plants along
roadways should be abandoned or  the use of tetraethyl lead in

Tomato plants grown in an atmosphere containing sulfur diox-
ide absorbed is in  an amount proportional to that present in
the atmosphere. The absorption was rapid and accompanied by
a release of hydrogen sulfide. The  absorbed SO2 'migrated* to
different  parts of the plants;  some  of it apparently  was
eliminated through the roots. This  can be regarded as proof of
the noncumulative toxicity of atmospheric sulfur. Much of the
sulfur absorbed was metabolized by the plants in the form of
sulfates,  amino acids, and sulfur proteins. The SO2 was of at-
mospheric origin, and both its absorption and the discharge of
H2S were related to  the presence of light and thus  to the
photosynthesis  of  the  treated plant.  (Author  conclusions

An estimate is made of the relative importance of the reduc-
tion of nitrate in the chloroplasts in the mitochondria and the
cytoplasm of barley leaves.  Because of  varying results with
different  methods of preparation  of  the cell organites,  two
techniques are used. The first involves immersion in an aque-
ous  medium, from which it is  possible  to  obtain n. fraction
which  is  rich in granules whose outer membranes are intact.
The second method, using lyophilised  leaves with centrifuga-
tion according to density, yields chloroplasts which retain their
enzymes  and  other hydrosoluble factors,  although  various
liposoluble factors can be lost. In chloroplasts obtained by the

first method, the activity of  nitrate reductase is very weak.
The second method permits calculations that indicate these or-
ganites contain about 60% of the activity present in the leaf.
The nuclear and mitochondria! fractions and the roots contain
little nitrate reductase. Cytoplasm is always  abundant in this
enzyme.  The addition of molybdenum to  the aqueous types
does not  increase their activity. (Author summary modified)

Because of the unreliability of chemical methods for determin-
ing whether acid smoke gases have damaged chlorophyll-con-
taining plant tissues,  numerous investigations were conducted
to determine the practicability of the spectroscopic pheophytin
test.  Specific goals   of the  experiments  were  to test if
pheophytin can be created by experimental exposure to gas, if
pheophytin is created by damages in open spaces containing
no source other than acid smoke gas, and  if leaf staining and
color changes can exist  where damages have not been caused
by acid smoke gas. As determined by several hundred  sam-
ples, the effect of acid smoke gases  can, once the  'charac-
teristic' leaf stains occur, be identified as 'smoke damages'  by
the spectroscopic pheophytin  test. However,  the method fails
when chlorophyll-carrying cells have been damaged by  very
weak  concentrations  of sulfurous acid to the extent that full
bleaching of the chlorophyll coloring occurs. It is also impor-
tant to distinguish  acid damage from  symptoms of  water
shortage, sunburn,  so-called frost drying and from typical au-
tumn coloring.

The frequent absence of a correlation between plant damage
and air pollution in the vicinity of a plant emitting 400 tons per
day sulfur dioxide  and 150 kg per day fluorine led  to studied
of the nature of the absorption  of both pollutants in plants.
Both fluorine and sulfur dioxide are absorbed  by leaves of  to-
mato plants in proportion to the amount applied. However, ab-
sorbed sulfur migrates within the plants and is distributed as
the sulfur normally found in  plants. Fluorine is accumulated
by the leaves, resulting  in eventual necrosis beyond a certain
limit;  these limits have to be separately defined for each spe-
cies of vegetation. Because sulfur is metabolized in part by the
plant, it cannot have a cumulative toxic effect when applied in
subtoxic  quantities.

                         All  specialists agree that  sulfur  dioxide and  fluorine  com-
                         pounds are particularly important plant toxins. Picea abies,
                         Abies alba, and  Pinus sylvestris,  by far the most important
                         trees cultivated in  Central Europe, are highly  susceptible to
                         these two pollutants. The damage caused  by  them reaches
                         alarming proportions, endangering the  existence of forests in
                         many areas. The total area of damaged forests probably ap-
                         proaches 400,000 hectares. Damages to land under cultivation
                         are less spectacular because growing conditions can be artifi-
                         cially improved. Pollution effects are often limited to the yield
                         or partial loss of quality for one growing season. The influence
                         of fluorine  on animal teeth and bones is well known: the ef-
                         fects can  be partly averted by adding correct amounts of
                         phosphate and calcium to animal rations or by  supplying feed
                         containing sufficient minerals. In general, research on the ef-
                         fect of pollutants on vegetation is  directed toward the absorp-
                         tion of pollutants, their transport in leaf parenchyms, and their
                         effects on physiological processes. Creation of new species or

                         was 40% damaged  68 days  after the beginning  of  the experi-
                         ment. At that point, the  plant  was shut down, and lichens
                         transplanted after this date were not so affected. Experiments
                         in a controlled environment with simulated outdoor conditions
                         gave similar results with this species of lichen.  This life form
                         would seem to be a good indicator for use in air analysis ex-

 formaldehyde with titration of the OH ion thus formed, distil-
 lation in iodine  solution and titration  with  thiosulfate, and
 distillation  in  iodine  solution and  precipitation  as  barium

 um sulfate after a preceding oxidation with bromine vapors or
 hydrogen peroxide. As determined by an investigation of  nu-
 merous plant samples, the amount of precipitation generally
 parallels the degree  of damage. Among  plants growing near a
 slag  burning dump, those nearest  the dump had strongly
 discolored leaves. The SO2 which these plants had taken up
 resulted in  considerable precipitation with the formation of
 crystals.  With  increasing distance  from   the  dump,  the
 precipitation decreased and became predominantly amorphous.

 Examinations of the forest vegetation and agricultural life in
 the surroundings  of  an aluminum plant over a  period of six
 years revealed intoxication and injuries to the vegetation by
 fluorine compounds.  The degree of injury differed in  correla-
 tion with the distance from the plant and the prevailing wind
, direction.  Further studies revealed that plums  were  a more
 sensitive indicator to fluorine pollution than  apples, pears,
 cherries, and grapes. Among vegetables the most striking dif-
 ferences were  noted  with leaf  vegetables  such  as lettuce and
 cabbage. Wheat showed higher fluorine  contents  than  rye.

Investigations  were conducted  to determine  the  degree of
growth inhibition in various forest trees exposed to hydrogen
fluoride emissions alone or to  simultaneous emissions either of
hydrogen fluoride  and  sulfur dioxide or sulfur dioxide  and
magnesite dust. Trees susceptible to SO2, and Mg are, in in-
creasing order of susceptibility, larch, pine, spruce, fir,  and
beech. Trees susceptible to SO2 and HF are in  increasing
order of susceptibility, aspen,  ash, beech, maple,  spruce, pine,
and larch.  Susceptibility to HF increases in the order pine,
spruce, fir. Unlike spruce trees, pines show no noteworthy in-
dividual  differences  in  resistance  to  air contaminants.  Re-
sistance in  spruce is affected by factors such as location and
water and  nutrient supply.  The  need to develop resistant
strains of spruce is indicated by the importance of the  tree for
the European forest economy.

The  direct and indirect effects of pollution  on humans,
animals, plants, and inanimate objects are  identified and the
two ways of limiting pollution by lowering the emission or am-
bient concentation level are analyzed. Pollution manifests itself
differently  on  various object  groups. The choice of criteria,
the relationship between ambient concentration and its effect,
the difference  between damage and impairment (exemplified
on plants) and statistical procedures which  should govern the
application  of criteria of ambient concentration and of its ef-
fects are discussed. Ambient  concentration limits can be set
only for a single clearly defined component (SO2, NO2 for ex-
ample), effects of combinations of pollutants can be measured
only on biological objects. Only a single ambient concentration
limit can be set for all object groups. The quantification of the
relationship between ambient concentration and action criteria
will of necessity be inexact. In the determination of ambient
concentration limits both human and  freedom of enterprise
must be considered among other factors in order to arrive at
the right balance.

The results of a study of qualitative and quantitative changes
of plant cultures in the area of fluorine emissions from an alu-
minum plant are presented.  Emissions considered included
hydrogen fluoride, carbon tetrafluoride, and solid fluorides as
well as carbon monoxide, sulfur dioxide,  and  similar  toxic
compounds. The circular experimental surface  areas (r equals
2.5m) placed at 100-200 m intervals in 3 directions from the
emission source were regularly investigated.  As criteria of
change sociability  coverage,  coefficient of relationship, and
domination were used. The number of plant species changed in
an irregular fashion with the distance from the emission source
and with length of exposure to emissions with the exception of
a route going through an even flat terrain. The coefficient of
relationship  behaved in a  similar manner. The total coverage
decreased towards the epicentrum and with the  length of expo-
sure to emissions. An exception was trifolium rubens, which is
a species  resistant to fluorine emissions. The  frequency and
coverage of certain species of the Daucaceae and Asteraceae
family also increased. Qualitative changes of plant cultures on
varying terrain thus  occur irregularly, while on even terrain
they bear a certain relation to the distance from the emission
source. The changes so far observed were of a quantitative
nature. Within a few years, extensive qualitative changes are
expected in the area with deposits higher than 500 kgf/square
km per year.

Sunflower, corn,  tobacco, and radish plants were exposed to
0-1.5 mg  sulfur dioxide/cu  m  air for 9-20 days in  special
vegetation chambers. Corn and sunflower reacted with 0.5 or
1.0 mg SO2/cu m  air to give an optimal yield, and a rise in
yield was established for radish and  tobacco up to 1.0 or 1.5
mg SO2/cu m air. Under the experimental conditions, the SO2
assimilated from the air represented the predominant source of
sulfur which, in general, makes possible normal plant growth.
The results demonstrate that  the sulfur supply from the air is
of special importance for plants with insufficient nutrition in
contact with plant roots. (Author summary modified)

\n experimental program designed to determine the effect of
fertilization on the  sulfur  content  of  spruce needles is
described. Needles taken from  trees  damaged  by sulfur diox-
ide were analyzed to  determine the characteristics of the sul-
                         fur  content. The natural  sulfur content of needles and  its
                         variation were determined before the fertilization process was
                         begun. Fertilizers of two types,  nitrogenous and  sulfurous,
                         were applied to controlled groups  of trees. The change in sul-
                         fur content of the needles as a result of the sulfurous fertilizer
                         was determined. The overall  effect of  the fertilization was a
                         decrease in sulfur content of all the treated trees. However,
                         the  results were  diverse and it is likely that they were  in-
                         fluenced by location. The analytical method used to determine
                         the sulfur content of the needless is described.

                         To  answer the question which  compounds of  tar  vapors
                         damage plants, and especially potatoes,  several of the  pure
                         components of tar were tested. Since only vapors evolving
                         between  100 and 300 C cause injuries, the experiments were
                         restricted  to  acenapthene, acridine,  anthracene,  carbazole,
                         chrysene,   fluoranthene,    fluorene,   napthalene   and
                         phenanthrene. Because  evaporation of solvents results in small
                         crystals on the epidermis, these substances  were mixed with
                         glycerine forming very small droplets  on the surface of the
                         leaves. Injuries occurred only with acridine, anthracene and
                         fluoranthene, but solely  when the plants were put in direct
                         sunlight after the fumigation. These three compounds have a
                         very similar chemical  constitution in  showing a  condensed
                         three  ring system in one plane. Other acene and anthracene
                         derivatives such as phenazine, xanthene, 2-methyl-anthracene,
                         9-methylanthracene and 9-10-dihydroanthracene, were also ex-
                         amined. During microscopic observation of the droplets, it was
                         found that droplet changes in regard  to a fluorescent reaction
                         resulted under the influence of  ultraviolet light. (Author sum-

                         in various concentrations of sodium fluoride. High  concentra-
                         tions of fluorine inhibited germination of pea and barley seeds
                         and, to a lesser extent, mustard and kohlrabi seeds. Seeds of
                         poppies and carrots were relatively unaffected. For the most
                         part low concentrations  of fluorine  had a stimulating effect
                         that was apparent in speed of germination and  overall ability
                         to germinate, as well as root growth and the growth of coleop-

                         on the germination  process. The  levels of other mineral  ele-

The injurious effects of sulfur dioxide on crop plants was stu-
died under a light intensity of 20 k lux and in the dark. The
plants were exposed to 20 ppm SO2. The  injury observed on
the leaves of both rape and barley, even under the dark condi-
tion, increased in degree as the exposure time was extended.
Rape, in the flowering stage, showed no significant difference
in susceptibility to the gas whether the plants were in the dark
or light; in the vegetative stage, the plant  was more severely
injured  in  the dark than in the light.  Barley, however, was
more  severely injured in  the light tha in the dark. The leaves
of both plants  absorbed  sulfur whether in the light or dark.
Particularly with rape, the  sulfur content  of  thy  leaves in-
creased linearly  with longer treatment time, showing a higher
sulfur content in the light than in the dark. The degree of inju-
ry appearing on the leaves correlated positively with the sulfur
content of  the leaves, but in rape the considerably high sulfur
content did  not cause   any visible injuries to the leaves.

Studies were  made to determine whether fluorine absorbed by
the leaves of tomato plants can be displaced toward the roots
and whether the fluorine  contained in the soil can be absorbed
by the roots and then displaced toward the leaves. In the first
part of the  study, fluorine was introduced to the aerial parts of
tomato plants, either by  soaking the leaves or the leaf stalks
with a hydrofluoric acid  solution of 4  g/1  of fluorine in two
tests, the first lasting 2 minutes, the second, 4 minutes. The
soaked leaves were rinsed  twice in distilled water and  their
fluorine contents were measured and proved to be, respective-
ly, 319 and 409 ppm, indicating that absorption of the fluorine
ion  is rapid.  In the second part of the experiment, tomato
plants  were grown in various cultivation  environments to
which fluorine solutions were added. Tabulated data for both
parts of the experiment revealed that fluorine moves normally
from the leaf  stalk of absorption to the leaflets, the stems
serve essentially as a passage area, an appreciable quantity of
fluorine is  still found in  the stem at the time of collection,
there is practically no  passage of fluorine to the roots,  and
that if the cultivation environment contains a large quantity of
fluorine, the  latter is  not  noticeably displaced  toward  the
leaves even if it is absorbed  in small parts of the roots.

The injurious effects of sulfur  dioxide on photosynthesis  and
absorption of sulfur into leaves of rice plants were studied. It
is shown that both visible actual photosynthesis are depressed
by fumigation  with sulfur dioxide. Visible photosynthesis was
completely inhibited one hour after the plant was exposed to
the gas, after being treated continuously at high concentrations
such as 20 and 40 ppm.  At concentrations of 6, 10, and 40
ppm, the depression of visible photosynthesis caused by fu-
migating with sulfur dioxide for one hour, was restored to the
original state two hours after the gas was removed, but was
not restored after fumigations at concentrations of 30 and 70
ppm. When rice plants  were fumigated with sulfur dioxide at
concentrations up to 20 ppm, the sulfur content in the leaves
increased significantly with  only a slight  increase as the con-
centrations became higher. The content of sulfur absorbed in
the leaves did increase, however, in proportion to the length
of the fumigation period. (Author summary modified)

Drustva, 17(l/4):5-ll, 1970. 5 refs.
Results are presented  of a preliminary  investigation of  the
mercury content of environmental samples, primarily of vari-
ous water, soil, and plant samples, in the neighborhood of the
mercury mine at  Idrija,   Yugoslavia.   The  measurement
technique was  activation analysis using a volatilization method
for mercury separation. Results show a wide range from ap-
parently normal background  (0.005-0.1 ppm) to very high levels
(10-100 ppm). The highest values are mainly due to aerial con-
tamination from the  mine flue gases.  More importantly,  the
results  show the ability of vegetation to  accumulate mercury
during growth.  (Author abstract)

decrease in assimilation and an increase in transpiration that
was followed by a subsequent decrease as cell destruction in
assimilation organs progressed. Gassing with low SO2 concen-
trations produced two completely different reactions. In one
case,  a clear  decrease in assimilation was observed following
exposure of needles to  1.7 ppm SO2, but further gassing with
a carbon dioxide balance was required  to increase transpira-
tion. In another case, 0.85  ppm SO2 produced a simultaneous
lessening of assimilation and transpiration. In field measure-
ments, a decrease in transpiration was observed only where a
decline in assimilation was  already apparent. These results are
compared with earlier, contradictory studies.

The composite effects on plants of sulfur dioxide and ozone,
S02 and PAN (peroxyacetyl nitrate) SO2, and nitrogen  diox-
ide, and NO2 and ozone were studied. Pinto bean plants were
exposed to SO2 or O3 only, to each gas alternately, and to a
mixture of the two. The degree of injury by the gas or  gases
was indicated in percentage by area of the leaves damaged. In
cases  where no geometric  effect occurred the damage to the
plant by the individual  gas had been great; damage from the
individual gas had been slight in those case where such an ef-
fect was observed. The geometric effect is produced when the
density of SO2 is rather low, generally 0.05-0.25 ppm. A mix-
ture of SO2 and O3 was applied to a tobacco plant; it affected
fully grown leaves as reported by Menser. In  experiments on
the composite effects of SO2 and PAN  on bean, tomato, and
pepper plants, PAN affected  mainly young leaves while SO2
affected  mature  ones.  These  effects were arithmetic rather
than geometric. The SO2  and NO2  were also studied in the
same  manner. When SO2  and NO2  were mixed, a geometric
effect  was conspicuous in damage to vegetables, the symp-
toms of damage by either of the two appeared about the same,
younger leaves being affected less. When treated with the two
gases alternately,  the damage  was greater if the plants were
first treated  with  NO2; possible causes  for  this effect are
discussed. No sign$cant composite effect of NO2 and O3 was
observed.

THE  EFFECTS OF AIR  POLLUTION  ON VEGETATION.
(Auswirkungen der Luftverunreinigungen auf die Vegetation).
Text in German. Staedtehygiene (Uelzen/Hamburg), 22(6):130-
136, 1971.16refs.
Generally two groups of air pollutants are distinguished  when
considering vegetation  effects. Inert dusts can be taken by
plants without injury; toxic gases, however, destroy them. Of
all forms of vegetation the forest has the highest dust filtering
capacity: one hectare of spruce forest binds about 32 tons of
dust;  1 hectare of beech  forest, 68 tons when the  dust  is
washed off by rain, the filtering capacity is restored  and the
dust is mixed with the soil. Of the gases, sulfur dioxide  is the
most  harmful. It is estimated  that about  200,000 hectares of
forest have been damaged  in the German Democratic Republic
by emission of SO2. The long-term maximum  alfewable  emis-
sion concentration for SO2 in Switzerland is 0.2 ppm, which
still seems to be too high.  The SO2 which penetrates into the
cells attacks the chlorophyll and causes chlorosis. It has been
found  that deciduous  trees  are  much  more  resistant  than
                        coniferous ones. Through adequate fertilization the resistance
                        of  plants  may  be increased; through  nitrogen fertilization
                        growth is stimulated and injuries can be healed faster. How-
                        ever, through the higher  assimilation, more pollutants  may
                        penetrate the plant  organs. Further studies are needed  to
                        determine which one of these processes prevails.

                        Investigations on the effects of coal gas on the growth of trees
                        are discussed. The trees were distributed over an area of 28.28
                        sq m;  1.545 and  0.772 cu K» of coal gas were introduced to the
                        soil daily. After four weeks of gas treatment, the buds of trees
                        which  were certain to die had a seemingly healthy appearance.
                        However,  a closer examination of the cross  sections showed
                        the buds of the plane trees, silver poplar, American walnut,
                        tree of heaven, and acacia were completely dead. The buds of
                        the maple trees and the horse chestnuts were still alive but had
                        a brown discoloration on the inside. Only the buds of the lin-
                        den trees still seemed normal. However, they did not sprout in
                        the spring. A closer examination revealed  that all roots,  with
                        the exception of a few strong main roots,  were dead. A large
                        quantity  of coal gas, introduced to the roots while in a state of
                        hibernation was  much  less harmful  than a  much  smaller
                        amount introduced during their growing  period. Some species
                        (tree of  heaven, locust, elm, and  acacia) showed signs  of
                        poisoning sooner, some (maple and linden) later.

                        Paddy rice, barley, tobacco, orchard grass, and alsike clover
                        were treated for two hrs/day for seven days  with sulfur diox-
                        ide concentrations of 1, 5, 10, 15, and 20 ppm. Treatment was
                        carried out in an exposure  chamber at 25,C, 20 klux  light in-
                        tensity, and under 76-90% humidity  variation. The experiment
                        did  not  demonstrate any  correlation between percentage  of
                        leaf injury and  increase SO2 concentration, nor established
                        whether the percentage of leaf injury is related to temperature
                        and light  intensity.  Injury rates  at  the  Vegetative  stage
                        decreased  in the following order: alsike clover, orchard grass,
                        barley, tobacco; in the flowering stage, the order was tobacco,
                        barley, rice. Leaves which had just  completed flowering  were
                        found  to have a high gas  interchangeability. Therefore, the
                        process of SO2 injury centers around center active leaves and
                        upward and downward leaves in accordance with the absorp-
                        tion process of  SO2 in  terms of the gas interchangeability of
                        the leaves. With increases in SO2 concentrations or treatment
                        time, injury progresses from the cell, depending on differences
                        in osmotic pressure.

OF INJURYtSYMPTOM IN  PLANTS  WHICH  ABSORBED
SULFUR DIOXIDE.  Nippon Shokubutsu Byori Gakkaiho, vol.
36:127-131, 1970. Translated from Japanese, lip.
An investigation  was  undertaken  to determine  the relation
between sulfur accumulation in plants and the development of
symptoms of injury after buckwheat was exposed to low con-
centrations of SO2, symptoms of damage began to appear  on
the first day after contact with concentrations in the 0.26 ppm
range, on the third day in the 0.13 ppm range, and on the 16th
day in the 0.065 ppm range. At the same  time, the inorganic
sulfur content of the plants increased. Soluble organic  sulfur
and protein sulfur, on  the other hand, showed almost no dif-
ference from the amount in control plants. Absorption of sul-
fur from the soil and the atmosphere is discussed.

THE  REDUCTION OF FRUIT QUALITY BY INDUSTRIAL
AEROSOLS.  Rostlinna Vyroba,  vol. 11:837-852,  1965. 2 refs.
Translated from Czech. 27p., 1966 (?).
A droplet analysis method for determining the intensity  of  in-
dustrial smoke products (soot, dust, and ash) on the surface of
fruit is described. The  method involves removing the products
from  a one sq cm section of fruit,  placing the products in one
cc clean or distilled water, then transferring the resulting solu-
tion to  glass  slides for microscopic examination. The method
gives  more precise and more reliable results than that in  which
the epidermis of the fruit is placed under the microscope and
the fruit evaluated by weight.  Based on observations in fruit-
growing regions  of Czechoslovakia, smoke products damage
fruit in  both the period of blossoming and the development of
fruit.  Blossoms damaged by  the products produce deformed
fruit with little resistance to  disease. Moreover, the smoke
products combine with the wax on the surface of the fruit to
form  an organo-mineral  layer that is insoluble  in  water and
which, by interfering with the penetration of solor radiation,
affects the coloration of the fruit.

Experiments were undertaken to determine if toxic dystrophy
of the liver in young pigs was caused by a deficiency of seleni-
um in their feed. In the organs and tissues of sick young pigs,
the selenium content was four to six times less than in healthy
young pigs. Toxic dystrophy was  experimentally induced  in
young pigs by giving them a dystrophagenous diet and carbon
tetrachloride. One  group of  animals which was given a dys-
trophagenous diet  and sodium selenite did not  become dis-
eased.

The amount  of  selenium  in  various  tissues  and organs of
chickens was dependent upon  the quantity of selenium in their
feed. When 0.1  mg  of sodium selenite/kg of feed  was ad-
ministered to hens, their egg yield increased 9.3%. The content
of  selenium  in  the  liver, ovaries, heart  muscle,  complex
muscles, and blood  cells, was also increased,  while it  was
decreased in the kidneys.

The injurious effects on sulfur dioxide upon plants are rele-
vant to  the direct rays of  the sun;  no  injuries were observed
during the night or in a dark room.  However, when a mixture
of sulfur dioxide and aldehyde was applied to plants, the same
injurious effects emerged  in  the dark room as under direct
sunlight. These effects are therefore not caused by the sulfur
dioxide  alone. Aldehyde, produced by the dissolution of or-
ganic acid present hi the plants, and a-Oxysulfosaure, a com-
pound of sulfurous acid and  formaldehyde produced by the
union of sulfur dioxide, were also involved. That the injurious
effects of sulfur dioxide  were limited to instances involving
direct sunlight was attributable to the fact that the formation
of aldehyde is facilitated by direct sunlight. The sulfur dioxide
penetrates into the plant foliage through the stoma as well as
the drainage hole on  the leaf margin. The stoma and drainage
hole smeared by vaseline showed no symptoms of injury. The
degree of effects of sulfur dioxide greatly differed due to dry
or damp air.  When the air was damp,  sulfur dioxide inhaling
the moisture was converted not only into a minute fog shape,
but also into relatively heavy sulfurous acid. Compared with
ordinary gas, its movement was slow  and easily stopped by
plants or other blocks, thus providing ample time for penetra-
tion into the foliage. The effect of sulfur dioxide upon the
yield of crops varied according to the kind of crops; the densi-
ty  of  gas and  weather  conditions,  with the  contact by
5/1,000,000 and more capacity of sulfur dioxide, increased the
injuries. Greater injuries occurred before and  after the blos-
som period. The contact of sulfur  dioxide after the blossom
period influenced the new seed quality. Lists of plants tested,
injuries  sustained,  and lengths  of testing  times are  also in-
cluded. Author summary modified)

The  first plant organisms damaged by sulfur dioxide are the
lichens on tree trunks. Herbs, grasses, and woody plants often
show typical damage at  concentrations as  low as 30 ppm.
Coniferous  trees are attacked  at  the tips  of the needles,
damage then spreading toward the needle base. The parts at-
tacked turn  red or whitish  in color. Grasses and  liliaceous
plants show brown spots at the tips of the leaves. Grass blades
become limp and are streaked with brown. When severely at-
tacked, trees, shrubs, and herbs show damage to the leaf sur-
face  between the veins. The site attacked turns yellow, brown,
or red  and the tissues dry rapidly. In animals, the respiratory
tract is usually affected. The reaction of insects such as bees
and butterflies is not known.

Secondary  damage from pollution   most  frequently  occurs
through  sunburn on  peripheral susceptible tree  stands  in
clearings of  wooded  areas. Such trees, damaged by the sun,
attract pests and die. This applies especially to pine stands. In
the pollution- exposed areas of Aichfeld near Judenburg and
Gailitz-Arnoldstein, needles  of  mature pine stands suddenly
turned  brown  in  1963 following the appearance of an addi-
tional pollutant (hydrofluoric  acid) into the already sulfur diox-
ide-polluted atmosphere (first area) and intensification of SO2
emission (second  area).  A  contributing factor was an  ex-
ceedingly cold winter with temperatures 4 to 5 C below the
long-term  average.  Pollution-  exposed  stands   are  more
susceptible to  infestation with  the  fungus  Armillaria  mellea
which  causes  great damage  in  Austria to pine, spruce, and
deciduous tree stands. Other pests which proliferate in pollu-
tion-damaged stands  are  Pissodes piceae,  Cryphalus piceae,
Ips typographus, and Pissodes harcyniae. Generally it is not
easy to prove a causal  relationship between  emission and
secondary damge: detection of damage in a pollution-exposed
area  is not sufficient proof. The task is easier where identical
or similar stands in  unpolluted areas are available for com-
parison.

                         origin were planted experimentally in many localities of Poland

                         using  some  American tree species to replace susceptible

                         was a  case  in point. Insect infestation was lower than in

                         the  Hylobius  beetle demonstrated the  superior regenerative

                         The conditions of plants in parks and gardens relative to the
                         atmosphere and to the soil  are discussed. A tall building can
                         modify  the  life  conditions  of nearby  trees,  since a  new
                         microclimate is established.  In the urban  atmosphere, conifers
                         appear  to be the most sensitive to the presence of atmospheric
                         pollutants. These pollutants most often  come from combustion
                         sources and internal combustion engines. The leaves of plants
                         are well suited to  retain the fine elements of particles, particu-
                         larly tars and oils. By settling on the leaves, these substances
                         form a film  which  reduces the respiration and chlorophyll
                         function of the plant. Among the conifers, spruce and douglas
                         are  the most  sensitive to  sulfur dioxide; 'among the broad
                         leaved  trees,  elm, birch, and catalpa are relatively sensitive.
                         The distribution of pollutants is influenced by topographic fac-
                         tors and meteorological conditions.  The tendency toward stag-
                         nation, accompanied  by the accumulation of  pollutants,  is
                         prevalent in shelter  areas and in areas where the air is  stable.
                         Temperature  inversions  cause an accumulation of noxious
                         products near the soil and  are, therefore, detrimental to plant
                         life. It is  recommended that resistant species  of  plants be
                         selected for the  parks and  gardens of urban areas. The soil
                         conditions which affect plant growth are also discussed in
                         detail.

Translated from Japanese, 14p.
Experiments  were conducted to determine the  effect of con-
stant exposure  to sulfur dioxide on respiration  of rice plants,
respiration being a major factor in their dry matter production.
Rice seedlings  were  also studied for  their ability to  regain
respiration by first subjecting them to gas treatment for one
hour and then removing the gas from the air flow. Sulfur diox-
ide  severely affected the respiration of rice seedlings, causing
a linear drop  in respiration with increases in gas concentration.
A concentration of 60 ppm inhibited respiration  after one hour
even before  gas removal, with  no subsequent recovery  of
respiration. At one ppm, the respiration rate without exposure
remained  almost  normal but  declined after  gas  removal,
without regaining the normal level after three hours. In experi-
ments on rice plants at the highest tillering state, gas concen-
trations of one, five,  10, and 15 ppm accelerated respiration,
while 40  and  60 ppm inhibited the respiration rate. The longer
the  treatment, the narrower the range of gas concentrations in-
ducing respiration acceleration.  When  the  respiration rate  of
plants at the  highest tillering state was  computed cumulatively
for  a four hour test period, it increased linearly with concen-
tration level  to a maximum at five ppm. The  curve dropped
after the maximum to the normal rate  level at  29 ppm. Thus,
concentrations above 28 ppm produce adverse effects. (Author

POISONING  OF DOMESTIC ANIMALS THROUGH COPPER

Several weeks  after reactivation of a  copper smelter on  the
border between the states of Hesse and Westphalia,  cattle,
horses, chickens, and sheep in the area exhibited symptoms of
poisoning.  Subsequently,  many animals died  or  had  to be
slaughtered. The poisoning was  traced to the copper- and ar-
senic-containing fly dust emitted by the smelter and deposited
on  plants and grasses in grazing pastures, particularly  in  the
presence of dew and fog. Early clinical symptoms of poisoning
included  conjunctivitis, stomach and intestinal  catarrh, secre-
tion of saliva, miscarriages, emphysematose foeti, retention of
afterbirths,  and  reduction  or  complete  stoppage  of milk
production.  Autopsies  of  deceased or  slaughtered animals
revealed  considerable enlargement of the liver. Liver copper
concentrations  were 80 mg/kg in cattle and horses and  75-250
rag/kg in sheep. Plant fly dust contained 2.5%  copper and 23
mg  arsenic  trioxide  (As203).  Symptoms  first appeared  in
animals 0.5-1.5 km from the smelter, but animals grazing as far
away as 4.5-5 km were also affected. Of 2100 cattle in the four
communities  closest to the smelter, 520 animals  perished. Milk
production in the four communities  was  reduced by about
75%. Copper levels in animals and animal organs (liver, Kid-
ney, spleen, heart, blood) are tabulated.

Principal advances in research pertaining to the gas resistance
of plants are reviewed. The influence of toxic compounds on
the anatomical-morphological  structure of leaves  and  the
physiological-biochemical  characteristics  of plants  is  con-
sidered. Also, the  species of plants resistant to various com-
pounds in  different physico-geographical  zones  have  been
ascertained. Investigators have undertaken detailed studies of
the chemistry of injuries to plants by acid gases, as well as the
chemical mechanism of transformation of sulfur dioxide in
plants  and  its influence on  the metabolism of carbon com-
pounds, with the  aid of isotopic techniques. Considerable at-
tention has been given to the development of methods for stu-
dying gas resistance of plants. Of major importance for a suc-
cessful  diagnosis and study of the gas  resistance of plants is
the establishment of direct indicators characterizing the degree
of plant resistance. The effects of ammonia, mercury, acids,
fluorine, chlorine, and other pollutants on plants are described.

The feasibility  of  regulating the gas resistance of plants by
means of mineral nutrition was established. Forage grasses ex-
posed to sulfur dioxide were more resistant when treated with
nitrogen and potassium. The positive effect of  nitrogen is ap-
parently due to its important role in protein metabolism, and
that of potassium, to its role in the  regulation of the permea-
bility and ionic behavior of the protoplasm.  Oxidizability,
ascorbic acid, water-holding capacity, and oxidation-reduction
potential can be used to indicate species differences in the gas
resistance of forage grasses. Under the influence of fertilizers,
the change of these indicators does  not always coincide with
the change in gas resistance. This makes it necessary to postu-
late that  the indicators are connected only indirectly with the
mechanism of plant resistance. (Author conclusions modified)

AIR POLLUTION TRANSLATIONS
The development of a biochemiluminescence method opens up
new  opportunities  for the study of the interpretation of the
biochemical aspects of the oxidation processes in plants under
the influence of sulfur dioxide. A set of electronic instruments
with a high  sensitivity  photomultiplier were  used to record
spontaneous and induced oxidation processes. Etiolated plants
of forage grasses were  more resistant to sulfur dioxide than
green plants,  requiring  concentration  10  times higher than
those required for green plants to produce damage. Under the
influence  of sulfur  dioxide, the  luminescence in etiolated
plants increases. The activity of  the luminescence  is more
pronounced  in  the  resistant species,   fescue,  and less
pronounced in timothy  grass.  Concentrated sulfur dioxide
depresses the luminescence of both species. In etiolated plants
there is no relationship between the amount of substances ox-
idized and the vulnerability of plants to sulfur dioxide. (Author

Etiolated and green plants of the meadow fescue and timothy
show statistically significant differences in  their vulnerability
to sulfur dioxide at nearly all ages, thus making it possible to
use the biochemiluminescence method for studying the gas  re-
sistance of plants.  A direct relationship was observed in etio-
lated and green plants of both species between the amount of
oxidizable substances, ascorbic acid, and vulnerability to sul-
fur dioxide. The degree of influence of sulfur dioxide on the
ultrafaint  luminescence  of plants depends on their age, with
the greatest effect observed  at the age  of greatest physiologi-
cal activity. Sulfur dioxide causes a luminescence flash which
is greater in the  meadow fescue than in the timothy. (Author

Following a  10-second  and  S-minute  exposure  to carbon-14
tagged sulfur  dioxide, meadow fescue and timothy showed
practically no differences in  metabolism of the main groups of
organic compounds.  Under the influence of fertilizers,  during
a S-minute exposure with C( 14)02, the polymerization rate of
carbohydrates was somewhat higher in  the fescue than in the
timothy;  the percentage of the labeled carbon  was higher in
the starch and lower in  sucrose. Changes in the chemistry of
photosynthesis may be attributed both to the indirect effect of
fertilizers,  to species characteristics, and weather conditions.
In the meadow  fescue, in  the presence  of  increased solar
radiation, improvement  in gas resistance under the influence
of fertilizers is associated with an increase in  synthesis of su-
                         gars and a reduction in the synthesis of amino acids and or-
                         ganic acids; in the timothy, on the contrary, an increase in the
                         synthesis of the latter compounds is observed. (Author conclu-

                         Forage grasses differing in gas resistance to sulfur dioxide also
                         differ in their content of oxidizable substances and ascorbic

                         The forage grasses meadow fescue and timothy, which differ
                         in gas resistance to sulfur dioxide, are also markedly different
                         during the tillering stage from the standpoint of the nature of
                         the changes  in their vulnerability in relation to gas  concentra-
                         tion. The fescue is characterized by an almost directly propor-
                         tional dependence, and the timothy, by a logarithmic  depen-
                         dence. During the ontogeny of the timothy, regular decrease of
                         gas resistance occurs,  and a decrease  of  the sublethal  and
                         lethal sulfur  dioxide concentrations results from intensification
                         of the physiological-biochemical processes with the onset of
                         the productive  stage.  During  ontogeny,  timothy  shows  a
                         general  increase in the concentration of the pigments without
                         any appreciable change in then*  proportions. Under the in-
                         fluence  of sulfur dioxide,  certain differences in the destruction
                         of individual pigment systems  are observed  in the plant spe-
                         cies  studied during their tillering stage. Low sulfur dioxide
                         concentrations apparently cause an intensification of the enzy-
                         matic oxidation of the pigments, while high sulfur dioxide con-
                         centrations, by inactivating the enzymes, cause a stabilization
                         of the content of the pigments. (Author conclusions modified)

STAINING  OF BUILDING CAUSED BY SUSPENDED DUST
(FOR THE  EFFECT OF TEMPERATURE GRADIENT).  Text
in Japanese. Kuki Seijo (Japan Air Cleaning Assoc.) (Tokyo),
5(4):6-12 1967. 12 refs.
Dusty air is responsible for the unclean appearance buildings.
A finished surface of a building reacts to the air surrounding it
and  creates a temperature gradient, thus explaining  the so-
called 'pattern staining*. An imbalance in temperature gradient
causes the inner structure to show through with black outlines,
and is caused by 'thermal precipitation* which takes plac when
the surface is cooler than  the dusty air. According to Epstein's
theory, if dusty air touches a heated surface, a vacuum (free
of dust) is  created between the surface and  the dusty air and
the  dust is repelled. The heated surface remains  clean shile
coole surfaces attract the dust  suspended  in the  sir. An al-
sbaster ceiling panel, wooden beam panel, and a heater behind
the  panel  wer used  to prove that the concentration of the
deposited dust particle is  directly proportional to the tempera-
ture  gradient. It  is possib to predict the concentration of the
deposited dust particles if the following are  known: 1) the air
velocity near the  surface;  2)  the temperature  defference
between the surface and  air flow;  3) the concentration of the
dust suspended in the air; and 4) the length exposure.

An  outdoor test which exposed metallic materials to falling
dust, S02, and salt particles  was  performed on the roofs of
buildings in 13  places in Japan selected at  random. Twenty-
nine kinds  of metals, including iron, steel, stainless steel, alu-
minum, and zinc plating were used. Severity of  corrosion de-
pended upon the severity of  air pollution, and the corrosion
was  related to the  amount  of  SO2 in  the ambient  air and
S04(2-) and Cl(-) in  the  falling  dust. Iron was the most cor-
roded metal, followed by steel,  SUS 22, aluminum, and SUS
27. Zinc plating and  metallic paints showed little tendency to
corrode (about 1/100 that  of iron). Dirt stains in metallic paints
were mostly  due to corrosion of iron  particles.  Experimental
corrosion of metallic materials was performed indoors using
SO2 gas, and periodic exposure to  clean water, ultraviolet light
(using an arc light), and heat to compare the results with those
resulting from outdoor exposure. The results did not correlate
well, since corrosion in the  ambient air was confounded by
other pollutant particles.  Therefore, corrosion tests under ex-
perimental  conditions should include pollutant particles found
in the ambient air.

Steel containing  a  small amount of carbon, electrolytic zinc,
and electrolytic copper in the form of thin plates 30 by 80 mm
with a  thickness  between 0.8 to 1 mm were  used to study the
corrosion mechanism at temperatures of 20, 30 and 40 C; a
relative humidity of 80%; and  an HC1 content of 0.0007  to
0.002% (by volume). The stationary state characterized by con-
stant quantity and composition of the corrosion products and a
linear dependence  of the corrosion on time was established.
After the stationary state  had been reached,  the  corrosion
kinetics iron were goverend by HC1 formation during the rust
development. With the  zinc  sample,  the   corrosion speed
decreased after  the stationary state  had been  reached. This
was due to a reaction of the hydroxide and the alkaline zinc
chloride with HC1, where soluble ZnC12 is formed. The speed
of this process is influenced by the transport of the  gaseous
HC1 to the boundary atmosphere/corrosion product, as well  as
by the adsorption  and  composition of the product. With the
copper sample, the decisive partial process of the corrosion
kinetics in the stationary state was the destruction of the CuCl
layer covering the  Cu2O layer. The process is likewise deter-
mined by the transport of the gaseous HC1 to the boundary at-
mosphere/ corrosion product, by the  HC1 adsorption, and the
composition of the product.

Palladium contactors for the international telecommunications
switchboard were stained at contact points,  lowering the effi-
ciency of the mechanism and shortening its working life. The
analysis of the stains led to the suspicion that organic as well
as inorganic substances and dust particles in air contributed to
staining by chemical reaction due to sparks  and  frictions. The
investigation of the atmosphere showed that minute positively
charged dust particles pass through the electrostatic  dust col-
lectors and are likely to adhere to the negative contact points.
Oleagenic floor wax emits gases that contain much turpentine
oil and the gases enter the switchboard room through the air
conditioning  system.  In addition, multipanel   oil  was  also
suspected of causing some damage. Simulation in the specially
constructed  dust chamber showed  that the charged particles
and multipanel oil as well as inorganic gases cause no damage,

but cigarette smokes, large fibrinous dust particles and espe-
cially the gases from the oil wax are detrimental to the contac-
tors. The solution to the problem of the stained contactors was
10 alter the  general method of cleaning the  floor by changing

The rate of corrosion of zinc  and cadmium deposits on steel
was studied in  field  tests in regions of the  Soviet Union that
differ widely with regard to climate and contamination of air
by sulfurous gases  and  seawater aerosols and also  in  ac-
celerated corrosion testing chambers simulating,  respectively,
heat and moisture, sulfurous gases,  and sea mist. Corrosion
time curves  obtained for the field tests show that the corrosion
of zinc can be accelerated 10 times  and that of cadmium 15
times in the presence of sulfurous gases and chlorides. The
rate  of corrosion of  chromated deposits is equal  to that of
nonchromated deposits. In all climatic regions  the appearance
of zinc deposits changed  more than that of  cadmium deposits.
Corrosion time curves for the chamber tests  show that zinc
deposits corrode two to three times more rapidly than cadmi-
um deposits and nonchromated zinc deposits twice as  rapidly
as chromated deposits. The rate of corrosion was lowest in the
heat and moisture chamber and highest in the sulfurous gas
chamber. However, these chambers do not  give scientifically-
based  quantitative  data  on  corrosion resistance of deposits
under  natural conditions  because  the coefficients of accelera-
tion obtained in the  same chamber are different for different
deposits. The sea mist an heat  and moisture chambers, but not
the sulfurous gas chamber, can be used for characterizing of
corrosion damage in  an industrial atmosphere. In the sulfurous
gas chamber, the concentration exceed that  under service con-
ditions by about 2-4 orders of magnitude.

Research on the mechanism and kinetics  of atmospheric corro-
sion  is taking place along the following lines: 1) electrochemi-
cal studies of atmospheric corrosion processes;  2) investiga-
tions of the effects of atmospheric pollution; 3) investigations
of the  influence of corrosion products; and 4) investigations of
the relation  between  prolonged  exposure  and  the charac-
teristics of  different climatic regions. Attention is drawn to
progress or lack of progress  in each field and to specific
problems requiring further study. A complex investigation of
corrosion along all the lines indicated should permit the formu-
lation  of  a precise  theory  of corrosion.  This  in  turn  will
facilitate the development of  scientifically-based engineering
methods of protection against atmospheric corrosion.

The influence of meteorological conditions, contamination of
the air, and the products of corrosion formed, on the rate of
atmospheric  corrosion  of metals  in  industrial, rural,  and
coastal regions of the USSR is investigated.  The climates in
the regions in which the tests were carried out differ  greatly.
The  mean  annual temperature varies  from 1.6 C  in the
Northern coastal region  to 15 C in  Batumi. The mean annual
relative  humidity  varies  considerably  less  (from  69% in
Moscow to 82% in Zvenigorod. The duration of wetting of the
metal by atmospheric precipitations varies from 1342  hr/year
in Moscow to 3161 hr/year in Batumi. The  variation in the
number of  hours of sunshine in these regions is about 2-fold,
in the velocity of the wind  5-fold, and in the contamination by
sulfur dioxide and salts of sea water 20 - 40-fold The results of
corrosion tests showed that depending on  the variation in the
climatological conditions the rate of corrosion  of steel and zinc
in the above regions varies 2 - 3-fold;  of copper, 4-fold; of
cadmium, 5-fold; and of  aluminum, 72-fold. The rate of corro-
sion of metals is lower in  testing boxes than in the open at-
mosphere. For steel, the rate in the boxes is  (25%) of that in
the open atmosphere, and  for zinc, copper, and cadmium the
factor is 33.67%. The rates of corrosion of aluminum in the
open atmosphere and in the testing boxes are the same in all
climatological regions. It  is  possible to make scientifically-
based calculations  on the  rate of corrosion of metals in the
open atmosphere  on  the basis of the  meteorological  factors
and the contamination of the atmosphere,  taking into account
the conditions of testing,  the  nature of  the metal,  and the
physicochemical properties of the products of corrosion. The
data obtained can  be  used by designers for  determining the
necessary protective deposits which must be plated on instru-
ments and installations. The results of this  investigation should
be used for the development of methods of accelerated corro-
sion tests,  and  for the  determination of  coefficients which
would convert the data of  these tests into those applicable to
service conditions. (Author summary modified)

The difference between stress corrosion and corrosion fatigue
is briefly explained. The cracking of metallic materials under
the simultaneous action of certain corrosive agents and static
tensile strain is designated as stress corrosion. Stress corrosion
is frequently  brought on by internal stresses within  the raw
materials themselves. Corrosion fatigue is, on the other hand,
the decline of the endurance limit of stress causeS by the ac-
tion of a corrosive agent. Two typical  examples of corrosion
fatigue are indicated. The durability of stainless steel in resist-
ing corrosion stress can be explained by its ability to form pas-
sive surface layers out of invisible oxide films,  which in turn
prevent corrosive agents from attacking the metal and so pro-
tect it from corrosion.

The  author  outlines  various  oil  refining equipment  and
processes. That the oil industry is as prosperous as it is today
is due to the scale-up of equipment for  meeting the rapid in-
crease in  the  demand of products, progress of process en-
gineering and  further advances in catalysts. The oil industry
involves political problems; for example most of the naphtha
is imported from the Middle East, where the future  supply is
insecure. Public nuisance is another big problem  e.g., desul-
furization  of heavy oil, removal of sulfur dioxide and water
pollution in the seaside industrial zones. (Author summary)

AIR  POLLUTION PROBLEMS IN  WEST  GERMANY  AND
THE ROLE OF INDUSTRY.   (Luftforurensningsproblemer i
Vest-Tyskland industriens innsats).  Text in  Norwegian.  Tek.
Ukeblad (Oslo), 116(45):1245-1247, Dec. 1969.
West Germany has  been occupied  in the  last decade  with
reducing emissions of dust and smoke. Effectiveness of  dust
filters has  increased threefold, and filtration is more economi-
cal. The dust content can now be reduced to 150 mg/cu m for
an emission  rate of 100,000 cu m/hr. In  1950, the dust  output
from the  West  German  cement  industry was 3.5% of the
clinker produced; in 1967, it was 0.15%.  Dust output  from the
manufacture of calcium carbide was reduced to 3 mg/cu m of
exhaust  gases. Attention now centers on  reducing sulfur diox-
ide emissions. An electric power plant in  Essen absorbs  it  with
a new type of  activated  carbon, recovering  the SO2 for the
manufacture of H2SO4, the cost per 1000 kWh being about 1
DM  (25  cents), and this can be further reduced. Government
standards  now limit the sulfur content of fuel oils to 1.8%.
About 20% of the total SO2 emission in West Germany comes
from sulfuric acid plants. A new 'double contact' process can
reduce SO2 emissions  of such a plant from 17 to 3 kg  per ton
of H2SO4 produced. Nitrogen oxides  emitted from nitric acid
plants  have been  reduced  by 50%  with  special absorption
equipment. New  legislation  sets a maximum  average  of  2
mg/cu m for fluorine  emissions, or 5 mg  for short intervals.
Readings as high as  2.7 mg have been recorded  above the
Ruhr from January 1, 1966, to December 31, 1968. During that
period,   industry  in   North  Rhine-Westphalia   invested
4,000,000,000 DM on air pollution problems related to existent
operations and about 275,000,000 DM  on those related  to new
ones.   Exhaust  purification  for  the  2-year  period  cost
3,000,000,000 DM, plus an additional 30,000,000  for research -
this  in  comparison  with   a gross   national  product  of
300,000,000,000 DM per year. The total amount spent by in-
dustry is  small  compared with the  damage caused, which
amounts to 50 DM per capita per year, or 3,000,000,000 for
the entire republic, not including  losses due to sickness  or
sanitation problems.

While in 1955 the extent of smoke  damage in the German
Democratic Republic forests  was estimated at 8000 to 10,000
ha, the questionnaires circulated among the county councils in
1956/1957 revealed 10,000 to  15,000 ha. The estimate for 1961
had jumped to 85,000 ha. Now, the area of smoke  damage is
200,000  ha  and,  according  to  the   prognosis  of industrial
development will soon increase by another 75,000 ha.  Today,
smoke is attacking about 7% of the entire  forest area and in
the very near future, this figure will increase to 10%. Forestry
enterprises are responsible for short-term planning within the
framework of the planned  preventive measures and the par-
ticular smoke damage pattern. Both for  long-term planning of
the development  of  economic areas,  and for planning of
economic measures suitable for the individual forestry enter-
prise,  a  framework  has  to be  found  based on  general
knowledge  of the  science  of smoke  damage which enables
separate localities to adjust their needs to  particular demands
of the individual instances. Using Czechoslovak experience, a
four- degree scale based on the proportion of severely  injured
trees in the stand, occurrence of decayed trees, structural for-
mation of  the stand, and extent of previous calamities  have
been constructed.  It is concluded that the task of forest
management is the elaboration of prerequisites for the success-
ful fighting of smoke hazard.

The economic damage to the tourist trade  in Italy is concerned
mainly with water pollution problems  (damage sustained by
those who  earn  their income  from bathing  beaches, lake
                         resorts, and the recreational use of inland waters, such as fish-
                         ing). Figures are also given on the damage to drinking  water
                         and water for  industrial use, damage to ecology, real estate,
                         buildings, and  automobiles. The  extra cost of housecleaning
                         and of extra power needed for lighting (due to decrease in-
                         cidence of sunlight) are also estimated. The city of Genoa was
                         chosen for studies of this type of damage.

                         A confrontation is made between  the costs of a national  pollu-
                         tion control program in Italy and the economic benefits that
                         would result. For the period 1970-1985, the cost of construc-
                         tion, maintaining and  operating  pollution control  measures
                         would be about 7.85-9.00 trillion lire, while the  direct benefits
                         caused by the  elimination by these types of pollution can be
                         estimated at 8.0-12.0 trillion. All figures are  based on the
                         monetary value of the lire as of 1968. The investment costs are
                         broken down into categories, which  include industrial  emis-

A summary of the basis  of governmental action in Great
Britain in the struggle against industrial emissions is outlined.
The regulations imposed by the 'Alkali Act' are in most cases
based on  'the most  practical means.' Standards are given for
chimney heights. Statutory  limits are given for various materi-
als emitted such as hydrochloric acid, sulfuric acid, nitric acid,
hydrogen  sulfide, chlorine, arsenic, antimony, cadmium, and
lead. The construction of  tall buildings tends to reduce the
benefits obtained by tall chimneys. A better knowledge of the
effects of pollutants  should be obtained so as not to burden in-
dustry  with unnecessary expense in their control. It is urged
that international standards for emission be adopted.

Prior to  a discussion  of present achievements in combating
pollution and noise in the cement industry, the composition of
emissions by this industry is reviewed. Apart from dust, waste
gases from cement kilns contain nitrogen, carbon dioxide, ox-
ygen, and water vapor. The sulfur dioxide concentration is low
because it is chemically bound as sulfate in the clinker and the
dust. No  gaseous fluorine emissions  have ever  been deter-
mined; the carbon monoxide concentration is  negligible. Dust
emissions sank from about 3.5% in 1950 to 1.5% in 1957, and
to 0.15%  of  the clinker  production  in  1967,  although the
production increased from  11 million tons to 33 million tons.
In the vicinity of the Westphalian industrial center comprising
15 cement plants, an average dust fall of 0.75 g/sq m/day was
measured  in 1950; now, the  annual average is down to 0.42
g/sq  m/day. The VDI  (Association  of  German  Engineers)
Guideline  2094  recommends  a maximum allowable emission
concention of 150 mg dust/standard cu m. In  1950, only 15%
of the rotary kilns were equipped with electrostatic precipita-
tors; in  1967,  more than  93% had precipitators.  The VDI
Guideline 2058 provides for noise abatement in the cement in-
dustry. It recommends limitation of noise in primarily industri-
al centers to 70 dB  and in residential  areas with interspersed
cement factories, to 55 dB/day and 40 dB/night.

THE APPLICATION OF AIR ANALYSIS TO THE EVALUA-

'Maximum  Emission  Concentrations' (MEC-values) are laid
down to limit permissible emissions. They are derived from so-
called tolerance limits which are obtained from the relationship
between the emission and its harmful effect. In the case of the
effects of sulfur dioxide on vegetation, it has been shown how
the tolerance limits are obtained from the threshold-of-irrita-
tion function. They are not identical to the MEC-values which
can only be derived  from them by  means  of  an additional
definition. Above all,  the permanently changing conditions of
emission are decisive for this additional difinition. This must
be taken into account if supervision of  the MEC-values is to
be made possible by the aid of air analysis. (Author summary)

Air quality criteria are valuable with respect to suspected or
actual effects of air pollution. They are derived in turn from
criteria which  describe, respectively, emission  and effects
criteria. A  model  is presented  for formulating a relationship
between suitable emission criteria and the corresponding ef-
fects criteria. The  model, which represents the average condi-
tions of various  groups of  objects, can be used for estimating
possible damages and should serve as a basis for establishing
emission limits.  Also discussed are  measuring techniques and
their application to emission control.

The city of Tokuyama  in Yamaguchi Prefecture reached an
agreement with Nippon  Chemical Industries, Ltd. concerning
the emission of chromium  compounds from its factory. Aside
from the various agreement terms on the pollution prevention,
monitoring, and control, the emission standard for the chromi-
um pollutants in air and water is recorded. The maximum al-
lowable concentrations (24-hour average) are  0.0015 mg/ N cu
m as  chromium trioxide in the atmosphere and 2 ppm (as
valence six ion) in water. Some  of  the measures taken are:
relocation of the sodium dichromate kiln stacks, improvement
of the electric dust collectors, and indirect drying process. In
addition to the agreement the followin data are supplemented:
the environmental standards for  chromium in various coun-

The  European Coal and Steel Community has proposed that
                         its six member countries adopt standardized functional respira-
                         tory   tests,  spirographic   terminology,   and   respiratory
                         physiopathological   symbols.  The  recommendations  are
                         presented along with the results of a statistical analysis of data
                         from spirographic examinations of 3000 subjects, 18-83, in the
                         six countries. Ventilation  values for spirographic measure-
                         ments should be supplemented by listing ventilatory frequen-
                         cy, and respiratory equivalents are to  be expressed in liters of
                         air ventilated per liter of oxygen  consumed or carbon dioxide
                         removed. The spirographic  method, rather than the Douglas
                         pouch, is preferred for maximum ventilation measurements.
                         The tests are to be recorded for three different frequencies
                         greater than 30/min, the duration of each test running between
                         15-30  sees.  The recommended  symbols  differ  from  those
                         proposed in the U. S., especially in that volumes, flows, and
                         concentrations are  designated by the same symbols for both
                         gaseous and blood phases. The statistical analysis indicated the
                         need to consider  the variation of ventilatory volumes with age.
                         Tables of standard values, as a function of age, vital capacity,
                         residual volume,  and forced expiratory volume, were obtained
                         by a statistical filtering out based on constancy of variance
                         with age.

In order to control the air pollution caused by domestic fires
and commercial and industrial heating plants in Paris, restric-
tions on the use of fuels of high sulphur content and certain
emission limits were established in the Orders of August 1964.
In order to judge the effectiveness of these new experimental
regulations, it was necessary to estimate  the amounts of the
emissions and  the  resulting  air pollution  using  available
statistics and taking the meteorological data into account. The
results,  which have been obtained from the yearly measure-
ments or estimates for five years and from  the monthly and
daily measurements for three years are set forth in the form of
symmarized   iagrams in this  report.  In spite of a noticeable
reduction in air pollution in 1965, it is not  yet possible to de-
cide upon the effectiveness of the new regulations. However,
this investigation leads  to formulating some hypotheses which,
if they are verified, may influence  future legislation for the
control of air pollution in big towns. (Author abstract)

not treated under these regulations because they would be the
subject of separate federal laws. The author would like to see
uniform national control of air pollution in Germany.

French legislation, which at first was only concerned with in-
dustrial emissions, has  now been  expanded to  include such
sources of atmospheric pollution  as: industry,  heating, au-
tomobiles, and  also conditions such as ionization,  radiation,
and noise. Regulations  regarding urban conditions are  also
covered.  The excerpts given  indicate most of the laws have
originated since 1961. Three organization charts  are provided
which indicate the different groups responsible for legislation,
control, advice  and research.  In general, the law of Aug. 2,
1961 establishes the authority to control  pollution which might
affect public health and safety, or the condition of buildings or
monuments. The correction of  the conditions is to be provided
for by decree or regulation which may be applied to the emis-
sion of pollutants, the construction of buildings, the equipment
on vehicles, and the use of fuels. The controls are assigned to
the appropriate  departments, with penalties which provide for
imprisonment as well as substantial fines. Of  various regula-
tions affecting the combustion  of fuels, the edict of August 11,
1964, (which  applied to  Paris), fixed zones of special protec-
tion in  which  it was forbidden to use heavy fuel oils containing
over 2%  sulfur, and decreed that the volatile material in solid
materials be limited to 15%. In the edicts affecting urban  con-
ditions, the creation of open  spaces and wooded areas  was
provided for in planning.

INDUSTRIAL ANALYSERS.  ((II controllo continue dell in-

Italian. Termotecnia (Milan), 21(10):558-565, Oct.  1967.
                         For protection against air pollution from increased vehicular
                         traffic, urbanization, and industry, Italy established a law on
                         air pollution control in August 1966. Some provisions of the
                         law are cited. A  monitoring system for continuous measure-
                         ments of air samples involves wind direction, registration of
                         concentrations, determination  of pollutants, and the emitter.
                         Better results could be obtained from a network of monitoring
                         stations at various cities, and a plan is  proposed for their
                         establishment and operation, where continuous measurement
                         would also be made of air temperature and humidity, concen-
                         trations of  SO2,  H2S, NO2,  CO2.CO,  and hydrocarbons.
                         Photographs showing equipment and apparatus for the stations
                         are reporduced. A schematic diagram depicts  the picoflux ap-
                         paratus for SO2 measurements; an electrical cell for measuring
                         H2S  is also shown. The URAS infrared analyzer is used to
                         measure CO2. Analyses for CO, hydrocarbons and dust are
                         discussed, along with the equipment for air pollution monitor-
                         ing in Frankfurt, Germany.

                         with  benzene and dilution with  n-octane.  The refineries had
                         0.1-40  mKg  microgram/100  cu m  (with  values of  0.8-40
                         mKg/100 cu m in coke shops), the chemical plant (pyrolysis
                         shop) 0.9-9.1 mKg/100 cu m,  and the city sections (distance 50-

                         maximal 3,4-benzpyrene concentrations. The emission was the
                         highest during full-capacity production, with 2-4-fold increase
                         in a contact coke plant of refinery No 2. By order of the city
                         sanitary physician refinery No2 was closed down temporarily.
                         The  furnaces  were supplied with  gas-forming  fuel and  her-
                         metization was carried out. It  was concluded that  within a 2-

                         Air pollution control measures  are necessary  at  the source
                         which  produces the pollutants,  at the point  where they are
                         emitted, at the stage of diffusion, and at the  point where the
                         pollutants finally  return to the ground. The control measures
                         for existing urban areas involve staking out  industrial zones
                         where all  residential facilities ought to be removed and creat-
                         ing so-called green belts or vacant lots.  In the case  of new
                         development areas, the air pollution situation must be studied
                         and it must be decided which enterprises are  allowed into the
                         area and  the  location.  Air  pollution  sources should not be
                         located in the main direction  of the wind  to the  city. Large
                         structures or buildings should not be erected  in the windward
                         and leeward directions of a source. The stack height of an air
                         pollution source should not be equal to the height of the sur-
                         rounding buildings. Two green belts should be created around
                         pollution sources. Trunk roads should run parallel to the main

direction of the wind. The area between the green belts should
be reserved for commercial purposes only. Continuous obser-
vations of  the  meteorological  conditions  in  the area  are
required. The knowledge of the dispersion conditions  and the
possibility  of temperature inversions must be improved. The
relationship between the general meteorological conditions and
the meteorological conditions in the vicinity of buildings must
be  studied. The  pluming  of the waste  gases, interference
phenomena in an area with many emissions, and the influence
of the design and shape of buildings on the degree of pollution
and on the distribution of concentration should be the object
of intense investigations.

The  burning of oil with  sulfur  content  exceeding 2.5% by
weight should be prohibited in  Sweden after June 30, 1969.
The government should be  authorized  to  lower the permitted
sulfur content of a fuel oil even further when economic and
technical considerations are favorable.  A graduation reduction
of permissible sulfur content from 2.5%  to  1% is anticipated.
The responsibility for enforcing  the suggested prohibition will
be entrusted to provincial governments, who will be permitted
to grant exceptions  from  the  prohibition  to  plants  having
satisfactory gas purification systems. Local authorities will be
granted the right to issue ordinances restricting the sulfur con-

indicate the sulfu content of a fuel oil at  the time of  its sale.
Persons violating the injunction will be subject to a fine or im-
prisonment. Factors leading to the proposal are the increased
acidity of precipitation and surface water in Sweden.

HOW EXTREME  ARE THE RULES  AND THE DEFENSES
AGAINST AIR POLLUTION/ (A che punto sono la normativa e
le difese contro  I'inquinamento atmosferlco).  Text in Italian.
Termotecnica (Milan), 23(5): 264-268, 1969.
The  new Law no.  615 against air pollution divides Italy into
two parts according to factors such as density of  population,
geographical concentration of industries, meteorological condi-
tions,  etc. The  Law provides  for three types of defenses
against air pollution:  the elimination or reduction of polluting
substances, the  separation of  polluting  substances  from
smokes and gases before they are vented into the surrounding
air, and the reduction of their hannfulness. Enforcement must
be directed first toward private  heating systems.  In this the
law follows the example of London, Pittsburgh, Saint Louis
and  other large  cities.  Fuels used  must  burn  easily and
completely, even in small systems. However, the law is not at
all clear in defining fuel quality. Furthermore, the same law
often contradicts other rules on fires, tax evasion, etc.  Besides
the measures provided by  Law 615, other  actions must be un-
dertaken in Italy to  improve air quality. It is imperative to con-
trol the population  density of urban areas, to increase green
areas,  to promote  the use  of  electric heating systems, to
                                                     205

SPECTION  OF  AIR  CONSERVATION.   (Cinnost   Statni
technicke inspekce ochrany ovzdusi). Text in Czech. Ochrana
Ovzdusi, no. 2:17-19, 1969.
Measures against air pollution, according  to Act No. 35/1967,
are characterized by the imposition of penalties in cases of air
pollution, by increased administration power of regional air
control authorities,  and by increased  responsibility  of  the
Ministry  of Forestry and Water Resources  in the field of air
conservation. The State Technical Inspection of Air Conserva-
tion  is under the direction of the Ministry. Its function is to
control sources of pollutants, measure emissions, provide ad-
visory services, impose methods for restricting the emission of
noxious substances, and to work closely  with health authori-
ties. It has the  right to initiate research  and development pro-
grams. One of its major objectives is the systemized control of
emissions from  such sources as power stations, heat plants, in-
dustrial boiler houses, fuels with a high ash content,  chemical
plants, metallurgical processes,  and  concrete works. Through
the State Technical Inspection of Air Conservation, the Minis-
try of  Forestry and  Water Resources is collaborating with in-
dustries on new plant design and applying rigid technical tests
to existing plants.  Inspection of control  equipment  is  the
responsibility of  district inspection  committees, which have
the right to fine  both  plants and individuals  responsible for
pollution.  It is hoped that better coordination  can be realized
between district authorities and the national committee. Such
coordination is needed to develop combustion tests for the ob-
jective control and determination of pollutants escaping from
boiler houses.

lated from Czech. Belov and Associates, Denver, Colo., 22p.,
April 20, 1970.
The Czechoslovakian Law No. 35/1967  Sb. has made it possi-
ble to create  a system of effective measures against air pollu-
tion. Fees for atmospheric pollution must be paid by any n»l-
lutor that  releases large  amounts of noxious materials into the
atmosphere, primarily ash  and  sulfur dioxide, in any degree
that exceeds  the  given standards. The protection  of the  at-
mosphere  is centralized directly by the Ministry of Forestry
and Water Economy and the  State Technical Inspection for
the  Protection of the  Atmosphere. Tasks  have also been  al-
located  to  the Hydrometeorological Institute. It is suggested
that the validity of the law be expanded to include such pollu-
tants  as secondary dust, steam traction, exhaust gases  from
combustion engines, radioactivity, and noxious fumes.

                         As is true for scientific disciplines in general, there has been a
                         'literature explosion' on the subject of air pollution  control.
                         The USA is far in the lead in the production of such literature,
                         followed by the USSR, West Germany, England, France, and
                         Italy.  Other countries were contributing about  10%  of  the
                         literature, as of 1963. THe VDI (Society of German Engineers)
                         began an air pollution documentation service in 1957. The
                         storage unit now  contains better  than 40,000 titles and over
                         230,000 card entries, arranged on a 3-track  system in terms of
                         type of pollution,  emission  source,  and  main subject.  A
                         description is given, with illustrative examples, of the manner
                         in which material is stored and retrieved.

                         A  control program is presented  which  is to be effective
                         throughout Osaka Prefecture which has long been developing
                         as  a large industrial area; the enormous economic activity  has
                         added muah to the pollution problem. Air pollution is severe in
                         the central anfi Hanshin coastal industrial  district, and water
                         pollution is significant in Yodo,  Kanzaki,  Neya  and  Yamato
                         Rivers. Water quality in Osaka Bay has deteriorated to the ex-
                         tent  of  ruining  the fishing  industry. The ground   settling
                         problem in East-Osaka,  and the  noise from Osaka  Interna-
                         tional Airport have invited many complaints. The pollution
                         levels are to be lowered to within the tabulated limits by 1980.
                         There are many necessary control measures, but the following
                         are especially emphasized in view of the national planning  pri-
                         orities. They are  the control  measures against stationary air
                         pollution sources, purification of coastal waters and rivers  and
                         streams, control of nuisances accompanying automobile traf-
                         fic, treatment measures for metropolitan and industrial wastes,
                         and the control of airport noises. In addition, surveillance  and
                         measurement systems as well as cooperation with th neighbor-
                         ing prefectures are indispensible. Detailed tables are given on
                         the target maximum allowable concentrations of sulfur oxides,
                         suspended particulates, and carbon monoxide in air as well as
                         for cyanides, alkyl  mercury, organic phosphorous, cadmium,
                         lead, chromium, arsenic, and mercury in general for water pol-
                         lution. Values for pH, BOD,  SS, DO and coliform  bacteria
                         counts are also given. The maximum allowable noise levels for
                         fiaytime, morning  and evening are also  listed.

                         under the  jurisdiction  of  the metropolitan government is
                         presetted. The area is a megalopolis with 11.5 million  people,
                         and the industrial and economic activities are increasingly ex-
                         acerbating the pollution  problem.  Air  pollution from  automo-
                         biles and factories is severe. It originates from the central  and
                         Joto areas as well as from factories along  the Arakawa River
                         and Sumida River. Water pollutio in Sumida, Naka, and Tama
                         Rivers is also intense. The pollution levels are to be lowered to
                         within  the  tabulated limits by 1980.  The  necessary  control
                         measures  are numerous, but the  following  are  especially

emphasized in view  of the national planning priorities. They
are  the  control  measures  against  stationary  air  pollution
sources,  purification of  sea  water  in  the  coastal areas  and
fresh water in rivers  and  streams, control of nuisances accom-

areas as deep as  four meters), and treatment  measures for
metropolitan  and  industrial wastes. In addition, the establish-
ment of nuisance monitoring  and measurement  system is
necessary,  and close cooperation with the neighboring prefec-
tures is indispensable. Detailed tables are given on the target
maximum  allowable  concentrations    of   sulfur   oxides,
suspended  particulates, and carbon monoxide in air as well as
cyanides, alkyl mercury,  organic phosphorus, cadmium, lead,

A control program to be  effective in the area East of Sagami
River within Kanagawa  Prefecture  is  presented. This area
serves as the mainstay of the Japanese economy, industries
such as electric power, steel, petroleum, chemicals and heavy
automobile traffic have  contributed  to  the chronic pollution
problems.  Air pollution  in the Taishi  and  Tajima areas  and
water pollution in Tama,  Tsurumi, and Katabira Rivers as well
as Tokyo Bay are extremely severe. The pollutant levels are to
be lowered to within the tabulated  limits by 1980. There are
many necessary control measures, but the following are espe-
cially emphasized in view of the national planning priorities.
They are the control measures  against  stationary air pollution
sources in  Kawasaki, especially purification of coastal waters
and rivers and streams, control of nuisances accompanying au-
tomobile traffic, and treatment measures for metropolitan and
industrial wastes. In addition,  surveillance and measurement
systems  as well as cooperation with the neighboring prefec-

                         which is being pursued from a  public lower court in possession
                         of a real estate court is the circuit court under which the lower
                         court falls.

The per capita income in Japan, which was 690 dollars in the
fiscal year 1965, will about triple over the next 20 years. This
does not mean, however,  that the individual property will in-
crease as much, since a good deal of the individual income
will be spent for the maintenance of clean air and water. Some
day, a special  tax called air tax will have to  be  raised from
each individual to pay for the enormous costs of anti air pollu-
tion measures. Such measures  require re-orientation of the
common thinking from the private-property-oriented-society  to
a society  concerned about  such matters and  willing to con-
tribute to this cause a certain percentage of their income.

24(1):99, April 1969.
Air pollution has been intensified in Mizushima, due to the in-
troduction of the steel and oil industries. A survey of subjec-
tive symptoms and  opinion on air pollution  was conducted
among 182 households in the  area regarded as most polluted
(called area A) and 88 households in apartments owned by one
of companies regarded as a polluter in this area (area B). Com-
plaints such  as eye irritation, frequent coughing and expectora-
tion, and malodorous air were  heard more frequently at A than
at  B.  People from area A, who once welcomed the introduc-
tion of industry, are much more displeased with it than people
from area B, who belong to  the industry.  However, the former
are becoming reconciled to this pollution. They do not believe
that the local government or industry will control air pollution.
Furthermore, they  have  little confidence in the  ability of a
civic  association to  eliminate  public  nuisances  and would
rather  move out of the  area  than oppose pollution. On the
other hand, people working  in the offending industry pay little
attention to  nuisances. It is concluded that the opposition of
residents to public  nuisances  should be  supported by physi-
cians, scientists, and other actively concerned persons.

Hyg. Tidskr. (Stockholm), no. 3:99-115, March 1969. 11 refs.
Annoyance reactions from  odorous and  particulate  air pollu-
tants were regarded  as medico-hygienic problems in Sweden.
Legislation in Sweden permits intervention based solely  upon
subjective annoyance reaction  to some extent. Nuisances  from
industrial plants are usually caused by odors  and particulate
matter. Complaints were reported in 78% of urban and 27% of
rural communities. The medico-hygienic evaluation of nuisance
from air pollution includes studies of the dose-response rela-
tionship between  the pollutant in the ambient air and the  ex-
tent and strength of the annoyance reaction. The  description
of the dose is often complicated by the fact that many odorous
substances are hard to detect while they still have odor. There-
fore, the concentration in the ambient air is often based upon
analysis at the source combined with meteorological spreading
calculations. From a statistical point of view, there is often a
satisfying correlation between predicted and actual concentra-
tions in the ambient air. The organoleptic principle of analysis
of odorous emission was used more frequently during the last
few years. Odor  threshold determinations were successfully
used in testing odor abatement equipment and in dose descrip-
tion around pulp mills. The frequency is calculated by which a
certain concentration is exceeded at different distances from
the source.  The  description  of  the  dose was  satisfactorily
worked out by the use of standardized,  sociological inquiries
with special attention to certain effects of interaction, such as
disquising of or differences in attitude. Response studies were
undertaken in Sweden around pulp mills  and oil refineries.

A SYNTHESIS OF THE STUDY.  (Sintesi dell'indagine).  In:
Public  Campaign Against Pollution: A Summary.  (L'intervento
pubblico contro 1'inquinamento: Rapporto di sintesi). Text in
Italian. Gianni Scaiola (ed.), Ita}y,-3une 1970, p. 13-62, 17 refs.

This report  provides a summary of  cost  estimates  and
economic benefits connected  with  a project  to  eliminate  the
principal forms of air and water pollution in Italy. This section
of the  report  deals with the  theoretical presuppositions and
methods of study used for the project  and  a  report on  the
methods and results of economic  studies  made in Italy and el-
sewhere. The pollution problem has been studied by  a variety
of approaches, which include biology,  ecology, city planning,
and public sanitation, but economic analysis has been sadly
neglected. Such analysis is a prerequisite  for a realistic strate-
gy in dealing with the problems.  Some basic problems facing
the economist are the best possible allocation of our limited
natural  resources and that of the possible  distribution  and
minimization of costs created by the pollution problems. There
needs to  be  a restatement,  for  one thing, of  what natural
resources are considered  to be in 'public domain'. Historically,
a first attempt of analysis of the economic implications of pol-
lution was that of the Mellon Institute in Pittsburgh, conducted
in 1913.  Its main weaknesses were the inordinate  attention
given to the computation of damages rather than of the costs
of prevention; The first study  to consider pollution damage on
a national scale was the Beaver Commission Study of 1954, in
Great Britain. This report is examined in  detail. In the United
States,  an estimate given  by the Harvard Business Review
projected the need to spend 275 billion dollars over the next 34
years in order to  eliminate pollution. President Nixon, in  his
1970 message to Congress, set the investment figures at 10  bfl-

lion dollars per  annum  for the next 5  years. In Italy, the    650 billion lire. A 1970 estimate of air pollution damages in
author Spirroni has estimated the annual cost of air and water    Italy gives a total figure of about 350 billion lire per annum,
pollution control, from industrial sources only, at 1.5-2.0 tril-    about 4/5 pf which is  traceable to domestic heating and au-
lian lire. The  portion to  be used for air pollution amounts to    tomotive traffic.

ATMOSPHERIC  POLLUTION IN  LATIN AMERICA.   Bol.
Ofic. Sank. Panam. 58, 241-9, Sept. 1964. Sp. (Tr.) (Presented
at the  Inter-Regional Symposium on  Criteria for Air Quality
and Methods of Measurement, Geneva,  Switzerland  Aua  6-
12, 1963.)
Latin America is an area which is experiencing a very rapid
population and industrial expansion.  Although  this growth is
very irregular, the  cities which exceed  a million inhabitants
and the  industrial  concentration in them is growing yearly.
This phenomenon has resulted in serious problems of air pollu-
tion in Sao Paulo, Brazil, Santiago, Chile, Mexico City, Mex-
ico, which are in need  of further investigation  and control as
quickly as possible. There are potential problems in Buenos
Aires,  Argentina, and in all  those  large metropolitan centres
which  are growing and industrializing rapidly. The situation
created in Lima,  Peru,  because  of the fishmeal  industry,
seems  to be fairly well  controlled.  The greatest necessity is to
train personnel capable of conducting studies in measuring air
quality and controlling  the contamination of the air. There is
also a  necessity to create a  consciousness of  the  seriousness
of the problem among government authorities and the public in
general. It is  hoped that the future  development of the In-
stitute  of Occupational Health and Air Pollution Research in
Santiago,  Chile, will contribute effectively to achieve these ob-
jectives.

Med. (Paris), 23(1): 63-82, Jan.-Feb. 1968. 57 refs.
In this W.H.O.-financed survey and visit to  four  institutes
each in Moscow and Leningrad, the state-of-the-art in Russian
air pollution  control is reviewed.  The  principal centers for
research are the Institute of General and Urban Hygiene 'A.
N. Sysin', several medical institutes, sanitary and epidemiolog-
ical stations, and other  centers such as the Institute for Indus-
trial Hygiene and Professional Diseases in Leningrad. Air pol-
lution control  consists  essentially of  the  following measures:
definition of air purity standards (much stricter than standards
in America),  and the  determination  of  minimal  permissible
levels by  means  of very precise physiological tests, such  as
the olfactory threshold  test, encephalography,  and dark adap-
tation.  Chronic tests are conducted  on animals  in specially
designed exposure chambers, with special attention to effects
on   the   conditioned   reflexes,    muscular   coordination,
cholinesterase  activity, urinary coproporphyrins, as well as he-
matological, biological and other physiological data. A Russian
commission was created in 1949 to determine norms for air
pollutants. Principal laws promulgated by the  Committee for
the Sanitary Protection of the Air are: construction of indus-
tries with some provision for removal or capture of toxic sub-
stances, prohibition of emissions of dusts an<* toxic gases into
the atmosphere, and a  classification of industrial centers ac-
cording to their harmfulness  to  health, with corresponding
zones of protection between the plant and the inhabitants. The
analytical methods used in the determination of CO, SO2 and
H2SO4 aerosols, nitrogen oxides, ozone,  and  permissible
levels  for both  daily and  one-time  exposures.  The general
results of 18 Russian studies on CO and nine studies on sulfur
oxides  are  tabulated, and  references  given  for  work  on
nitrogen oxides,  3,4-benzopyrene, and ozone. The theoretical
basis for the combined effects of pollutants is discussed.

Air pollution derives from three principle sources: oil refining
and  petrochemistry (20%), home  heating  (60%), and  motor
traffic (20%). In  Milan and Turin,  smog in the atmosphere has
reduced the  lifetime of automobile finishes by  50%. Italy has
only recently  confronted the  air  pollution problem, and few
Italians realize the high cost of its prevention.  A company in
the city of Cornigliano has spent  1.5 billion dollars for equip-
ment to combat air pollution. Proper adjustment of home heat-
ing equipment would diminish smog by 40% and would give a
20-25% saving on fuel oil. The Italian law of July  13, 1966  di-
vides the entire nation into two control zones: (1)  communities
in north central Italy with 70-300 thousand inhabitants or spe-
cial air pollution  problems, and insular Italian communes with
populations ranging from 300,000 to one million; (2) communi-
ties of north central Italy of 300,000 or more and of southern
Italy with one million or more. Factories and plants are sub-
ject to regulation when their power output is more than 30,000
kcal/hr. No  limitations are  made  on  combustible liquids and
gases;  petroleum distillates such as kerosene and gasoline with
10% or less  sulfur; coke with 2%  or less of volatile materials
and 1% or less sulfur; or coal with 13% or less volatile materi-
als and 2% or less sulfur.  Wood and charcoal  are prohibited.
Limitations are placed on combustible fluids with  more than 5
Engler degrees of viscosity at 50 C and 3% or less sulfur con-
tent. Plants  must conform to  these regulations by December
31, 1969. More than 75% of this article is concerned exclusive-
ly with water pollution and the establishment of a 'Po Valley
Authority' to deal with water  and soil pollution  problems  of
that geographical area.

entity. Concern for the cleanliness of the atmosphere did not
become a worldwide health and economic problem until the
years following World War II. Emissions  from coal-burning
power  plants  are  and  will  for  the  next  30  years  be
Czechoslovakia's  chief source of atmospheric contamination.
Tunnel' research, work done in physics, chemistry, and biolo-
gy, should make it possible to survive periods of polluted at-
mosphere without health and economic crises. Both emissions
and imissions are serious, and  must be controlled  by legisla-
tures  and industries according to the environmental situation.
Solid  and  liquid  particles  dispersed  in  the  atmosphere are
termed  dispersive and colloidally dispersive aerosols,  accord-
ing to the size of  the paniculate matter.  Studies are being
made of aerosol classification,  electrical and  mechanical pro-
perties, particle coagulation,  and naturally  occuring aerosols.
This rapidly increasing study of air pollution  is resulting in a
new technology.

QUESTIONS  OF THE POLLUTION OF THE NATURAL EN-

Ochrana Ovzdusi, vol. 1,  Jan.  1969. Translated from Czech.
Belov and Associates, Denver, Colo., 12p., April 20, 1970.
                         Among the main themes of the  1968 Intergovernmental Con-
                         ference on the Biosphere was the pollution of the living en-
                         vironment. Reports submitted to  the conference noted the ob-
                         vious connection between water,  air, and soil pollution and the
                         damaging effects of pollution on  man and vegetation. Both air
                         and water pollution were the result of increased utilization of
                         fossil fuels, increased production of organic chemicals,  ur-
                         banization, and the rapid rise in motor vehicles in  the past
                         decade. Since  the beginning of the sixties, the sulfur dioxide
                         and carbon monoxide content of  air has been increasing, while
                         the pH of atmospheric precipitation has been decreasing. The
                         damaging effects of carbon monoxide on the central nervous
                         system and on blood circulation have been established, as has
                         the relationship  between  atmospheric  pollution and  chronic
                         bronchitis. Since industrial production in industrialized coun-
                         tries will roughly double within the next 20 years, preventive
                         measures  are  imperative  to  save the  living  environment.
                         Technology as it exists today must be intensively applied, and
                         research  and development must be  intensified. Also of ex-
                         treme importance is the cooperation of the medical and biolog-
                         ical sciences in the clarification of the mutual relations and
                         mechanisms of the  action of noxious materials. International
                         organizations should decide which organic materials should be
                         the primary object  of  research  and  control.  In  addition,
                         methods of unified  control should be studied as a means of
                         achieving world control of the atmosphere, soil, water, and or-
                         ganisms.
