        AIR  POLLUTION  TRANSLATIONS:
    A  BIBLIOGRAPHY  WITH  ABSTRACTS
                             VOLUME  2

                           INTRODUCTION
     This volume of "Air Pollution Translations: A Bibliography with Abstracts"
is the second in a continuing series of compilations presenting abstracts and
indexes of translations of technical air pollution literature.  It is published as an
integral part of the Air Pollution Technical Information Center's  (APTIC) assigned
task of gathering, processing,  and disseminating the world's technical literature
on air pollution.  At least 95 percent of the entries have been translated for
APTIC's Translations Section by outside contractors.  About 2 percent have been
obtained by screening published translation documents and 3 percent by screening
the  output of other translation services within and without the Federal Government.

     The 444 entries are grouped into 12 subject categories.  Within the categories
the  entries are arranged in ascending but not necessarily consecutive numerical
order using the APTIC "accession number preceded by a letter which denotes its
category.   The letter designates the section of the bibliography in which the
abstract can be found. As an example, the number A-6462 refers to Section A,
Qeneral, and to accession 6462 within it.  The highest accession number covered
is 11667.

     The language distribution is: Czech - 20, Danish - 3, Dutch - 9, French -
46,  German - 217, Hungarian - 1, Italian - 37, Japanese - 38,  Norwegian - 1,
Polish - 15, Russian - 38, Serbo-Croatian - 1, Slovak - 6, Spanish - 1, and
Swedish - 11.

     An Author Index, Language Index,  and Subject Index are included in which the
entries are referenced using the letter-numeral accession number.  The Author
Index lists the first  author and,  separately,  any co-authors.  The Subject Index
lists descriptors taken from the APTIC  microthesaurus, and other  terms that
most nearly indicate the essence of the document.  Cross-references have  been
made when the descriptor consists of more than one significant word, when the
most significant word does not appear first, and  to group generically similar
concepts.  For example, "Manganese compounds" will also be listed under "Chemi-
cal  compounds. "

     NAPCA personnel may obtain copies of the full translations abstracted here-
in by directing requests to the Air Pollution Technical Information Center.

     Non-NAPCA readers may, upon request to  the Air Pollution Technical Infor-
mation Center,  borrow the full translations abstracted herein for a period of

DETECTION AND PREVENTION OF AIR POLLUTION
IN THE U.S.S.R.  (Defection et prevention de La pollu-
tion atmospherique en U.R.S.S.]   Translated from
French.  Pollution Atmospherique, No. 31, p.  273-283,
July-Sept.  1966.
The problems of the toxic amounts of air pollutants (CO,
SOz, ^804, NO,  and 3,  4-benzopyrene) are described
and the criteria for standardization in Russia are given.
The methods for detecting toxic proportions of these
pollutants are given in detail, the techniques used for
animal experimentation,  and studies of the tests appli-
cable to mankind and the  techniques of applying them are
described in particular.  The paper mentions that since
chronaxie was judged insufficiently sensitive, the Soviet
authors resorted to electroencephalographic methods
which  reveal an electrocortical reflex for small amounts
of polluting agents.  These  tests involving instantaneous
maximum admissible concentration are  supplemented by
statistically analyzed experiments on animals.

     The possible use of ozone for sterilization of areas such
     as maternity clinics and contagious disease wards is
     discussed.  Ozonization also occurs naturally.  About
     3. 5 mg of ozone per 100 m-^ of air  has been found at
     Chamonix.  Ozone  generators are discussed which use
     atmospheric oxygen as the source of the ozone.  Ozoni-
     zation is ideal for asepsis because the operation of the
     systems can be controlled electrically and equipment
     needs  cleaning only once or twice every two years.
     Ozone may also offer a convenient  solution for everyday
     sterilization problems.

PYRITE FLOTATION WITH THE USE OF FLUE GASES.
Translated from Russian.  Soviet Journal of Non-Fer-
rous Metals, £(4):22-26, April 1963. 5 refs.


Methods of controlling the pH value in pyrite flotation
are discussed.  With a pH value close to 7 the process
proceeds actively.   The use of CO2 in alkalinity reduc-
tion was demonstrated in laboratory  research, the pro-
cedure being due to the following type of reaction:  Ca
(OH>2 + CO2 = CaCO3 + HzO.  It was  found that when the
pulp was agitated with flue gases a rapid reduction took
place; after 3 to 5 minutes, there was a reduction in
alkalinity from  500 to 700 gm of free CaO per cubic
meter of pulp until phenolphthalein tests showed no
color.   The use of the flue gases makes it possible to
obtain high technological indices without using the pre-
liminary thickening operation for pyrite-containing
products or pyrite flotation modifying agents. Applica-
tion of this technology in the pyrite flotation of Degtyarsk
copper ores at the Sredneural'sk plant made  it possible
to achieve the following:  (1) increase production of high-
quality flotation pyrite concentrate by 1. 5 to  2 times;
(2) to raise the  grade of general pyrite concentrate from
3rd to 2nd grade; (3) to increase sulfur extraction by 5
to 7 percent on reflotation;  (4) to exclude thickener and
reduce water consumption by 50 percent.  Capital  expen-
ditures for mounting the installation  were estimated at
a. total of 200, 000 rubles and operating costs were esti-
mated at 247, 000 rubles.  Annual savings from the tech-
nology are over 760, 000 rubles.  When H2SO4 is used
and its mean consumption is 5 kg/t ore, other conditions
being equal,  the operating costs  will increase by 145, 000
rubles  and the  economic efficiency will  be correspon-
dingly reduced.

     French.  Tech.  Hosp. Medico-Sociales Sanit.  (Paris),
     2^18): 16-17, March 1947.  1 ref.


     The use of ozone for sterilization of habited rooms is
     discussed since  ozone is known to destroy 80 percent of
     the bacteria present.   Ozone, an allotropic form of
     oxygen, can be produced by permanent installations
     which are operated automatically or semiautomatically.
     Ozone  has been used as a. tonic to stimulate the digestion
     of bedridden persons,  and also as a deodorizing agent,
     such as in the  Armentieres Asylum for the Insane, in
     dissecting rooms, and in hospitals.  It is known to induce
     an increase in oxyhemoglobin level in anemic patients.
     Ozone  generators are described with emphasis upon the
     suitable use of several types of generators according to
     their design and performance.

     An apparatus is described for the separation of a dust
     fraction >3 f and <5 M .  The apparatus is a. combination
     of a microcyclone and a membrane filter. A test aerosol
     CaCl£ solution was used to determine the efficiency and
     flow characteristics of  this  microcylone.  A flow rate of
     10 1/min.  is recommended for this apparatus in order
     to separate particles  of <3 u.

The observations of a patient who had worked in a plant
for 6 months handling toxic products of the "White Spirit"
type are given.  He showed signs of chronic lead poison-
ing; however he did not touch any toxic products that
might have contained lead.  After extensive examination,
it was  found that the patient had minimal thalassemia, a
hereditory blood anomaly which was not of great conse-
quence to  his health and  which would not prevent him
from working in any way.

na Voronezhskom  i Efremovskom Zavodakh SK. ]
Translated from Russian.  Kauchuk i Rezina, No. 3, p.
36-37, 1966.

Waste emission both in the factory area and in the hygienic
control zone around it (300-500 m  from the factory) were
studied both  qualitatively and quantitatively.   While pol-
lution did not exceed the established limits in the factory
areas, it did in the control zone surrounding the factories.
Contaminants were butadiene,  isobutylene, styrene,
benzene and  ethanol vapors.  Most of the pollution was
caused by  styrene-butadiene rubber processing in the
belt casting machine.  Large amounts of hydrocarbons
were  given off  by shops producing  isoprene and latex.
Pollution of the surrounding air also came from exhaust
ventilation of the factories  and  open pits of chemical
waste.  This resulted in a fall of 1200 metric tons in
Voronezh and 700 tons in Efremov per year.   Measures
for the control of exhaust ventilation from the factories
are urged.

Emphasis is placed on the importance of NO2 in air
pollution and urges that as much effort be exerted in
abating pollution due to this gas as to SO^ or 303 which
are currently under extensive  study.  The paper de-
scribes the  experimental study done by the U.S. Bureau
of Mines, and discusses the results of a similar study

STATUS AND  DEVELOPMENTAL TRENDS IN AUTOMO-

Motortechnische Zeit,  6/6):277-280,  June 1965.  6  refs.

The fields of application of Diesel and Otto motors, of
two-cycle and four-cycle systems, and of supercharging
are investigated.  Attention is called to the tendency to-
ward increase in power and in piston displacement and to
the increased commonness of motors with overhead cam-
shafts.  Considerable successhas been achieved in attempts
to improve the combustion in Diesel motors.  The in-
creased use  of V motors  is remarkable. Lastly,  atten-
tion is called to new types of possible motors for automo-
tive use.  It  must unfortunately be concluded that the  fuel
cell and the gas turbine will find no widespread applica-
tion in automotive uses at least for a long time to  come,
The NSU oscillatory motor has been able to achieve a
good initial success with  the production of a small sports
car.  Nothing can yet be said as  to the  extent of its later
use.  (Author's summary,  modified)

THE FORMATION OF NITRIC OXIDE DURING COKING.
[Stickstoffmonoxid in Koksofengas. ]  Translated from
German.  Brennstoff-Chemie, 47J9):270-273,  Sept.
1966.

Experiments were conducted to determine where and
when nitric oxide  is formed during the coking process,
and the manner in which the nitric oxide content of coke
oven gas changes  during the process of coking.  The
experiments were conducted on a small scale,  employing
specially designed apparatus  with the thermal energy
being provided by an electric heater,  in order to eli-
minate the possibility that coking fuels are responsible
for the formation  of nitric oxide.  It was found that
nitric  oxide begins to form during the first state at
which  gas is driven off; and that the extent to which it
continues as the temperature is raised depends on the
type of coal, its granular structure, and the temperature
rise.  Formation  appears  to be complete by the time that
the coking coal reaches a temperature of 400° C.  In the
case of ground coals,  the finer the grains the lower the
formation of nitric oxide,  and vice versa; the reverse
being true for  coal dust obtained by sifting coal  that
had been stored in the open air.   The NO contents of
subsequently heated alcohol extracts from coals are
approximately the same as those  of the same coals
directly heated in a helium atmosphere, and are from
four to twelve times as great as  the volumes contained
in the  distillation gases obtained during the coking pro-
cess.  This indicates that approximately 90 percent of
the NO which is formed during coking is subsequently
decomposed by reactions with the other distillation pro-
ducts.   NO is not formed,  as formerly believed,  through
oxidation during coking, but rather from the decom-
position of substances which are formed when coal is
stored in the open air.

In order  to analyze •working conditions in the production

pollution were collected in furnace sections  of sulfuric
acid shops at  12 chemical plants.   Technical progress,

 the introduction of new calcining methods for pyrite,
 the mechanization of many manual operations,  the in-
 troduction of automation features, better ventilation
 and other means have improved working conditions in
 kiln shops of sulfuric acid plants.  The concentrations
 of SC>2 in a number of plants producing sulfuric acid
 have dropped to permissible levels.   The reduction  in
 SO,  concentration to permissible levels and the marked
 reduction in clinker dust have been achieved even during
 increased technical progress,  greater charges of raw
 materials and gas per cubic meter of furnace and cubic
 meter of building  volume and  the greater production of
 sulfuric acid plants.

THE INCINERATION OF URBAN SOLID REFUSE IN THE
MILAN PLANT. [Incenerimento dei rifiuti solidi urbani
nell'impianto di Milano. ]  Translated from Italian.   Fumi
Polveri (Milan), 7j4):70-78, April 1967.  8  refs.

The plant consists of a pit where refuse is  placed, a
bridging van to feed the furnace, afurnace, heaters,
filters, a chimney, water  purifiers, a. central station
for electricity,  and heat exchangers.  The  composition
of solid refuse varies according to locale.  The elemen-
tary composition of the Milanese refuse is  C-56 percent,
H2-5 percent, O2-36 percent,  and N2-3 percent.   The
Milan plant burns  up to 600 tons/day, and the heat pro-
duced is harnessed to produce electrical energy by means
of a 9200 kVA generator.  The hot vapor products could
be used for industrial heating.  The smoke particles are
removed by the  use of suitable electrostatic precipitators.
The water is purified in a  cement basin under the cooling
system. A flocculation apparatus  in this basin purifies
the water by means of chemical reagents.  The cost of
the plant is 5.8 million Italian lire per day.  The cost
per ton is  between 1460 and 1340 lire which is less than
the 1550 lire it costs to operate other plants.

lated from German.  Tonind. Ztg, Keram. Rundschau
(Goslar), ^p_(10): 441-449,  1966. 7 refs.

Previous investigations into the effect of dust emitted
from cement kilns on vegetation have shown that the
chemical and mineralogical properties of that dust are
poorly delineated.  The results of chemical and  mineralo-
gical investigations and measurements of the pH-value
of 18 various kiln dust samples show that the alkaline
reaction of dust with a pH-value higher than 10 depends
primarily on the content of  clinker phases.  The segre-
gation  of dust in electrostatic precipitators leads to an
enrichment of clinker phases in the preseparating chamber.
Consequently the emitted dust in cleaned kiln waste gas,
which corresponds at the best with the composition of
the dust in the reseparating chamber of  the precipitator,
contains  no or only small quantities  of clinker phases and
therefore reacts only slightly alkaline at pH-values lower
than 10.  The results of the chemical and radiographic
analyses are tabulated showing the source of the dust,
the chemical composition of the 18 dusts analysed,  and
the pH of a dust-water suspension.

 AIR POLLUTION AND CITY PLANNING.  [Luftverun-

 Praventivmedizin, Vol.  11,  p. 601-621,  Nov. -Dec.
 1966.  73 refs.

 The causes of air pollution in the cities  are industrial
 processes (furnace firing),  household heating,  small
 businesses, and transport systems.  Measures suitable
 to fight this pollution must attack either at the source
 (improvement of incinerators, filters,  purification of
 waste gas, etc.  ) or by permitting a faster distribution
 and dilution of the  pollutants in the  air,  which can be
 promoted by measures related to city planning.  Some
 possibilities are:  the location of industrial emitters  of
 pollution in that sector of a  city "with  the least wind fre-
 quency and screening by parks, increase of the ventilation
 effect in a city by an appropriate layout  of the streets, the
 promotion of an open building pattern, minimum heights
 for the smoke stacks of industrial producers of pollution,
 development of main traffic routes  without intersections,
 and detours for  through traffic, etc.  The most important
 causes of air pollution in the cities are the sources of
 industrial energy  in the  form of large-scale incinerators,
 the heating of households and the  exhaust gases of automo-
 tive vehicles.  Burned are  coal and oil or products made
 of these substances.  Incinerators using coal dust and
 outmoded incinerators are particularly important
producers  of air pollution.

Difficulties that may be encountered in a. large steam
generating refuse incinerator are discussed in detail.
Means of solving these difficulties by improvements and
changes  are described for the individual plant compon-
ents.  It is  concluded that future plant construction
could be improved by using tube clusters with separation
throughout the entire length; cleaning tubes with soot
blowout and by streams of water; limited corrosion of
newly constructed furnaces on the heating surface by
eliminating the superheater tubes from the flue gas path;
limiting the attrition in the combustion chamber by
appropriate cladding; protection of tube sections from the
flue gas  stream by covering them with fitted  trays; opera-
tion of refuse incineration plants at temperatures  no
higher than 250° C.

INVESTIGATION OF OIL FURNACES FOR SINGLE
FAMILY HOUSES.   [Undersc/gelse af oliefyr pa villa-
kedler. ]  Translated from Danish.  Varme, 30 (5):
124-127,  Oct.  1965.

A survey  of 101 randomly chosen oil-fired heating plants
in single family houses was conducted in Denmark.  The
CO£ level, soot content, and temperature of the flue gases
from  each furnace were determined.  Criteria for proper
combustion were at  least 10 percent CO^ in the flue gas,
and a. maximum soot level of  1-2 on the Bacharach  scale
(0= white, 9= black). Flue gas temperature  above 250°
C were considered as excessive heat loss. Absolute
minimum  criteria "were  8.0 percent CO;? and soot at 3 on
the Bacharach scale.  Results: 51 percent of  the plants
produced  too much soot; 62 percent had less than 8.0 per-
cent CO£; and 78 percent had more  than 20 percent chim-
ney loss due  to excessive flue gas temperature.  At cri-
teria  of 8.0 percent  CO£,  3 Bacharach soot and 250° C
flue gas temperature, 9 percent were acceptable. Chang-
ing the CO2 criterion to 10 percent,  only 4 percent of
the units were acceptable.  Graphs  of the data are pre-
sented, and recommendations for educating oil burner
owners are made.

Exhaust gas  emissions from  gasoline operated cars with
four-stroke engines are reported for hot and cold starts,
and the results are compared with those of a previous
study and with a theoretical prediction.   Hot starts pro-
duce much less hydrocarbon and CO emission than cold
starts.   The  effects of water-cooling as opposed  to air-
cooling and automatic as opposed to manual choke are
discussed.

THE SULPHUR PROBLEM AND AIR POLLUTION.
[Svavelproblem och luftfororeningar. ]  Translated from
Swedish.  Annual Report of the National Academy of
Engineers, Sweden,  p. 29-34, 1967.

Past and present sampling programs in Sweden show that
content of sulfur dioxide in the air has  increased con-
siderably with a simultaneous increase in the proportion
of sulfur in ionic form in precipitation. The result has
been a. marked increase in acidity of rain water and in
surface water.   The levels of acidity in western Europe
are discussed,  and a map presents the average annual pH
content of precipitation. The effect of  low pH levels on
soils and forest growth are discussed.  The contribution
of industry to the pollution problem, and the effort made
to control pollution are also discussed.  Recommenda-
tions are given for means of controlling the pollution,
in Sweden, from sulfur compounds.

ATMOSPHERIC POLLUTION BY WASTE GAS FROM
CUPOLA FURNACES: GAS CLEANING. Translated from
French. Fonderie (Paris), Vol.  204, p. 54-62, April 1965.

The composition of waste gases from  cupola furnaces
where pig iron is being melted,  is discussed  in relation
to cleaning methods in use by the foundries concerned.
Gas cleaning methods, such as a centrifugal and improved
venturi scrubber (on a hot blast cupola,  8 t/hr), and a
filter gas cleaning installation (hot gas cupola,  12  t/hr),
are described and characterized as excessively costly.
Pollutants discussed, with quantities tabulated, included
various types of dusts,  CO,  CO;>,  and SO2. The improve-
ment  of the hood gas cleaning installations  (with a  cold
blast  cupola, 3 t/hr) is suggested as feasible and eco-
nomically realistic.

THE ROAD OCTANE NUMBER OF COMMERCIAL AUTO-
MOBILE FUELS.  [Die Strassenoktanzahl handelsublicher

mobiltech. Z. (Stuttgart),  bl_ (3): 93-96, March [1965? ].

The road  octane number of six Swiss regular and  high
test gasolines were determined in 38 different European
automobiles.  It was found that some cars tend to knock
during acceleration while others showed knock at  high
speeds.  This is caused by the difference in antiknock
properties of volatile and less volatile gasoline compon-
ents.   The introduction of tetramethyllead in Switzerland
should improve the gasoline quality since it adds a vola-
tile antiknock  component.  For acceleration knock the
research  octane number of the gasoline and its volatile
components  is important.  For high speed knock the
research  octane number as well as a good motor octane
number are  important.

der Stadtwerke Dusseldorf,  Kraftwerk Flingern. ]
Translated from  German.   Brennstoff-Warme-Kraft,
_14(5):234-236, 1962.

The experimental refuse incineration plant  in Duesseldorf
consists of a charging facility,  several consecutive roller
grates and a traveling grate.  These units are coupled
and electrically regulated. The experimental plant was
put into operation on  March  21, 1961,  and by the begin-
ning  of February  1962 it had processed 140, 000 m3  of
refuse in  about 3500  operating hours.  The  comparison of
the official measurements for  the incineration of Duessel-
dorf refuse onforced-feed and travel grates  with measure-
ments in the experimental plant show the following advan-
tages for  the experimental plant:  Its firing  efficiency is
83 percent, approximately 30 percent  higher than the tests
on forced feed grates.  Since the firebox temperature is
correspondingly higher,  it fulfills all hygienic require-
ments which can be made of a  refuse incineration plant.
The accumulation of  fly ash  in the raw gas in considerably
below the values  derived in comparable tests  with force-
feed  grate.  In the summer months  it is  1 gm/m3,  in the
winter months it is 2 to 2. 5  gm/m    No noxious compon-
ents were detected in the flue gases.   The results confirm
the belief that the roller  grate is suitable equipment for a
refuse incineration plant.

The refuse power plant in Munich is described and the
seasonal changes of the garbage collected (composition
and heating value shown in graphs) are described in com-
parison to those in Antwerp, Rotterdam  and Vienna.  The
power plant burns approximately 60 percent coal dust
and 40 percent garbage in separate combustion rooms of
a common high-pressure steam generator.  The first
version of the plant has a capacity of 68 million watts
and supplies  steam for a. long-distance heating system.
After the second  construction phase and A capacity of 100
million watts, all garbage  collected in the city of Munich
can be burned in this plant.  The installation is shown in
a diagram.  Purification of the flue gas  is emphasized.
An electrofilter providing 99. 75 percent dust removal is
mentioned, and the pneumatic transport of flue ash from
the boiler to  a collecting bunker is described. The prox-
imity of an airport limited the height of  the smokestack
to 80  meters.
The development of a waste incineration plant with heat
utilization in Stuttgart Germany is discussed and the
essential elements of the plant are described.  It incor-
porates the knowledge gained from existing refuse  power
plants and experimental plants  adapted to local conditions.
The power plant burns heavy fuel oil and refuse in  sepa-
rate combustion chambers  of a common  steam generator,
Electrofilters with a 98  percent degree of  separation are
planned for removal of dust.  The heat produced is fed
into the city heat supply via the steam collecting lines of
the power plant. The heat utilization system is illustrated
and discussed.  A steam generation of approximately 30
tons/hr per refuse furnace is  expected.  Economic as-
pects, including capital cost,  are briefly mentioned.

 incineration are discussed.  The properties of refuse,
 the possibilities of influencing the heating value,  and the
 technological processes of household waste incineration
 are discussed,  and the requirements for the construction
 of the firebox are deduced from them.   The incineration
 process can only proceed satisfactorily if the following
 basic conditions are fulfilled:  The trash must have a
 satisfactory supply of oxygen;  the trash and the oxygen in
 the air  must have as  close a contact as  possible,  for
 example by loosening the fuel bed; and a complete com-
 bination of the oxygen with the trash requires sufficiently
 high ignition and combustion temperatures. The  types  of
 trash incineration, the dust problem, and heat utilization
 are also discussed.

TRASH INCINERATION ACCORDING TO THE VOLUND
SYSTEM. [Die Mullverbrennung nach dem System VolundJ
Translated from German.  Brennstoff-Warme-Kraft,  14
(5):219-223,  1962.  13 refs.

The installation of St. Ouen (Paris) and its operational
results are presented as  examples of the  Volund trash
incineration system.  The trash is piled as high as 30
meters and fed into  the filling funnel, which unilaterally
tapers downward, by two orange peel buckets (one in
reserve) each "with 3m^ volume capacity and  a load capa-
city of 6 tons.  The  trash moves through a shaft to the
drying grate where it is dried by the radiation from  the
drying chamber and the convection of the  flue gases  rising
out of the incineration chamber.  The flue gases with a
high steam content "which are produced during the  drying
process are passed  through a  13.5 m long vapor channel
into the mixing and after-burning chamber.   On a  second
grate, the incineration grate,  the trash is finally ignited
and burned.  From the experiences of this installation
which has *. throughput of 323, 000 tons per year of trash,
the largest of its kind in Europe, a combination of the
rotary-drum furnace with a waste heat boiler was devel-
oped which has favorable space utilization through com-
bining the drying, incinerating,  and heat transfer  com-
ponents into a single unit.

 Some economic considerations  on refuse incineration,
 particularly on the problem of conditions suitable to the
 utilization of heat produced, are given.  The guarantees
 and construction conditions which must be  considered  in
 the evaluation of a trash incineration installation are dis-
 cussed.  Low flue gas velocities must  be chosen and
 opportunities for the removal of flue ashes inside the
 boiler must be created, in order to keep the abrasive
 effect of high sand content in the trash on the boiler tubes
 low.  Flue gases from trash incineration must be cooled
 before entering the boiler to a point below the softening
 temperature of the trash ashes. Clogged tube arrange-
 ments are above all to be avoided in the connected heating
 surfaces, since deposits which cannot  be removed by the
 ordinary cleansing apparatus,  such as  ball-moving and
 soot blowers,  will of necessity have to be removed by
 hand.  Slag must be discharged without raising dust and
 must be tightly air-sealed against the firebox.  A high
 quality dust-removal device must be present. The Martin
 system, the Sao Paulo incineration installation,  and the
 trash power plants now under construction  in Rotterdam
 and Munich are characterized.

The extension and modernization of the refuse furnace
plant located in Hamburg, Germany by the  addition of two
Von-Roll refuse incinerators -with a capacity of burning a
charge of 200 tons per 24 hours, each with one auxiliary
waste-heat boiler (with a boiler power  of 15. 5 tons per
hour) is  described and illustrated.   The experiences
gained in the operation of these furnaces are reported.
When three more  of these furnaces will be  operational, it
will be possible to burn more than one million m3 of gar-
bage annually and to produce 60 to 70 GWH.  Further
development of  the system will lead from an incinerator
with a waste-heat boiler to a uniformly structured garbage
incinerator with an initial charge of 200 tons per 24 hours,
which will require considerably less space.
The basic construction principles of a cell grate incinera-
rator trash disposal installation system are described.
Such installations  (of which some 274 have been built
since 1901) are suited for a capacity of roughly 175 tons
per 24 hours. Utilization of the heat produced generally
can be considered only in terms of steam or hot water
production, primarily for supplementing an already estab-
lished heating network.  Linkage with an electrical cur-
rent generation system is scarcely  economical in this
size range.  The installation is illustrated by  a diagram
and photographs.

502-508,  1961.

On the basis of a detailed analysis of refuse composition
in Berlin,  a. complex refuse processing scheme is pro-
posed.  Household refuse is utilized in the following
manner:  25 percent (the fraction over 60 mm) is incin-
erated with heat utilization for power  and steam genera-
tion,  20 percent (fraction of 0-4 mm)  is sintered and
used in the building industry, and 48 percent (fraction
between 4 and 60 mm) is composted into fertilizer.  The
process involves magnetic  separation of iron,  sieving,
centrifuging,  incineration,  and sintering.  It is especially
adapted to the economic conditions prevailing in Berlin.
Special equipment, such as vehicle  scales, locomotives,
telephone networks, and the vehicle cleaning machinery,
are operated  economically,  and efficient administration
procedures are possible.  The proposed multi-function
plant is compared "with the  latest comparable installa-
tions in other cities.   The effective utilization  of the
resulting ash sinter for building materials is detailed.
Regarding gaseous combustion products, the flue gases
of the sinter belt, with a temperature of approximately
200° to 250° C, can be used for biothermal composting
or  for drying green fodder.

Polyvinylchloride and other  organic material containing
chlorine is converted to hydrogen chloride and chlorine
during incineration and thus  can cause serious damage
to incinerators by corrosion.  Air pollution damage is
indicated only in  terms of flue gas composition.  The
corrosion mechanism was studied in detail and equations
describing the interaction bet-ween HC1  and iron oxides
were formulated.  The  corrosion rate was found to de-
pend on the concentration  of  the gaseous HC1 and Cl2,
the temperature of the tube surface,  and the concentra-
tion of the  chlorine compounds at the tube surface.
Chemical analyses of corrosion products are given to-
gether with case  histories of corrosion damage.  The
corrosion process is explained in terms of iron chloride
and iron oxide formation.

Various  aspects  involved in the planning of refuse incin-
eration plants are discussed.  Detailed data of the Essen-
Karnap power plant which serves a very wide area of
refuse collection, are  given.  This plant is the largest
refuse incineration plant existing at present.  It has a
capacity of 2000  tons of domestic and industrial  refuse
and 2000 tons of  sludge per  day.   Performance data,
components of the refuse power plant, supply and storage
facilities for household refuse, discharging of refuse,
refuse transportation and loading, incineration of used
oils,  slag transportation and treatment, and furnace
operation are described.   Simultaneous co-incineration
of high-calorific  value  industrial refuse is being attemp-
ted experimentally.   A large portion of the acid-forming
ingredients undergoes  chemical reaction with the refuse
slag and  fly ash originating  from powdered coal firing,
thereby reducing the emission of SO2, 803,  HC1,  etc,
into the flue  gas.  The  aim is to establish a  ratio of
industrial wastes to domestic refuse which will provide
the desired flue gas composition.  At present refuse to
be incinerated must contain less than 1 percent sulfur.

and furnace design.  The ranges of refuse calorific value
(kcal/kg) and the method of flue gas cooling (chiefly by
steam generation,  in one case air, one water, one  clari-
fier sludge drying) are tabulated.  The following grate
systems are used in the individual plants: moving grate,
advancing and retracting grate, rotating and tipping
grate, and Volund rotating furnace.  By 1970 there will
be an installed capacity of 3 million tons  per year in
West Germany.  This assumes planned and on-going new
construction in Berlin, Frankfurt, and Munich, as  well
as in eight other cities.

types of oil fired furnace chambers  are used:  the tem-
perature of the combustion gases is  kept low by the ad-
mixture of secondary air, preventing the slag  from
baking together.   The steam boilers generate steam of

84 atm and 450°  C and have a. capacity of 27 to 34 tons/
hr each.  A new  autoclave process for sludge clearing is
also being designed.   The sludge is sterlized by heating
to 200° C, the colloids are broken, the sludge is filtered
and the dry sludge is ground and used as fertilizer.   Two
hundred tons of dried  sludge (40 percent water content)
will be produced per week.  Eventually the plant may be
enlarged to supply some 450 tons of dried sludge per
week.  It is estimated that 50 percent of the sludge will
be used  in agriculture and the remainder, representing
about  10 percent of the entire amount of refuse, will be
incinerated.

 COMPOSITION OF REFUSE AND REFUSE INCINERA-
 TION.  [Mullzusammensetzung und Mullverbrennung. ]
 Translated from German.  Aufbereitungs-Technik, 4(12):
 561-565,  Dec. 1963.  7 refs.

 An attempt is made to characterize refuse by its constit-
 uents.  The refuse is differentiated according to various
 mixing proportions  of the lignitic constituent and the  coal
 component.  The kinds of mixtures within each component
 have been classified in accordance with their percentage
 of really  combustible materials and the content of real
 slag.  The burning conditions in these groups,  i.e. the
 quantities of smoke gas produced and the burning temper-
 ature as a function of the useful heating power,  can be
 determined provided the estimated melting point of the
 slag is taken into account.  It is advisable to judge the
 burning conditions  on the basis of  the types  of refuse,
 according to the  region,  the customs  and working condi-
 tions of the population and the  supply  of fuel and the heat-
 ing methods practiced in the region.  The composition of
 refuse from some European and American cities, and its
 effect on  combustion is  discussed.  Analyses of the slag
 from refuse are  important.  The properties of the slag
 influence  not only the temperature and the combustion
 conditions in the different layers of the combustible,  but
 will determine whether  the flue gases are suitable or not
 for the production of energy. It is especially important
 to know the temperatures that  can  be  obtained in the com-
 bustion chamber, with the different types of refuse.  The
 admissible temperature of the fire-bed is determined by
 the supposed melting temperature  of the slag.  The air
 excess will be determined correspondingly.  The melting
 point of the refuse slag which may not be exceeded lies
 between 1000 and 1440°  C.

 The content of CO2, NH^, and ^S, as well as general
 climatic conditions were measured in hog barns having
 slot floors and a manure pit within the barn.  The mea-
 surements confirmed that no objectionable concentrations
 of undesirable and dangerous gases are formed, even
 during prolonged storage of  liquid manure.  Pumping
 off or drainage  of the feces-urine mixture without prior
 stirring into a pit located outside the  barn produced a
 minor but harmless elevation of the gas concentration.
 Mechanical,  hydraulic  and pneumatic stirring in order

 The engineering history during the 20 year development
 of the Von Roll refuse incineration system is described
 and the results evaluated.  The experiences and observa-
 tion of the rotary  drum furnace in Basel led to the
 replacement of the drum by a perpendicular shaft (slag

ing and flue gas utilization,  purification of flue gases,
e. g. by dust precipitation and elimination of air pollution.
Settling chambers, wet scrubbers,  cloth filters,  cyclones,
and electrostatic precipitators are discussed.  Domestic
incinerators are criticized as unsatisfactory,  causing 25
percent of all complaints for excessive smoke and odor
in New York.  It is concluded  that most existing refuse
incineration plants are not substantially automated and
require a large number of operating personnel.  In
most cases the purification of waste gases is not satis-
factory.  Maximum emission standards, and their
variation in different cities are discussed.  Refuse incin-
eration and technology is  probably functioning at a higher
level in Germany than in the USA at the present time.  It
is emphasized that refuse incineration technology require s
a larger amount of scientific research than it has been
receiving in the past.  Some novel developments,  in-
cluding a double mantle upright cylindrical combustion
chamber, a rotating drum installation and a moving-grate
firing installation (which is illustrated) are discussed.

INCINERATION OF REFUSE IN A HIGH-PRESSURE
STEAM PLANT.  [Erfahrungen mit der Verfeuerung von
Mull in einem Hochdruck-Dampfkraftwerk. ]  Translated
from German.   Energie, IT_ (8):317-326, Aug.  1965.

Refuse is used as a fuel in two high-pressure super-
heated steam boilers at the "Nord" power station of the
Munich municipal system.  The boilers are designed
for burning coal or refuse, either alone  or in combina-
tion. The technical features of the plant are given in de-
tail, including  the  site-map of the station,  boiler design
data, construction history 1961-65, firing mechanism,
and  experience in operation.   The design and operation
of a refuse shed and crane are discussed, and experi-
mental runs  with coal and refuse  firing are described.
Refuse averaged 45-50 percent of ash and was found to
contain only  1.64-2.48 percent of scrap metal.   The
storage bin and loading area did not attract rats  of ver-
min. Refuse feeds of 25 tons/hr  were achieved with a
caloric output of 1200-1300 kcal/kg.  The percentage of
refuse in the overall operation will be about  35 percent.
The refuse-generated power would have negative prices
due  to the city  subsidies.  The financial advantages
would benefit the city  administration  and the  government.
Refuse combustion will supply about 10 percent of the
total future power requirement of Munich.  Air pollution
is not discussed, except indirectly, in terms of the high
combustion efficiency of the coal  burned, and the pre-
sence of an electrostatic precipitator in the system.

Aug.  1964.

A plant designed for the incineration of 600 tons of refuse
daily,  and also  capable of burning used oil, is described.
Three steam generators produce a maximum of 15 tons
of steam  per hour for remote heating and power pro-
duction.  The plant design is illustrated and discussed
in detail, including storage of the refuse, the slag
generator, an electrical current generating plant, and
a system for utilization and disposal of used oil from
industrial plants.  Air pollution aspects are mentioned
only incidentally,  in connection with flue-gas recircula-
tion for control of combustion-chamber temperature.
The gas  is transported from an electrostatic filter
through a mechanical  flue gas purifier.  The presence of
large amounts  of fly ash and the advantages of an angle -
tube boiler for easy cleaning  of heating surfaces are
mentioned.   The experiences gained during the first
year of operation are  also discussed.

HEAT TECHNOLOGICAL MEASUREMENTS IN A
REFUSE  INCINERATING PLANT.   [Warmetechnische
Messungen an einer Mullverbrennungsanlage.]   Trans-
lated from German.  Tech. Uberwach.  (Dusseldorf),
4(6):211-214, June 1963.

Measurements conducted in an experimental refuse
incinerating plant to establish the heat technological
parameters that may serve as a basis for a larger
project are  reported.   The following measurements
were made:  the refuse combusted and the amount of
ash removed; the amount of fuel oil used; the amount of
steam generated; the amount  of cooling water used; the
pressure at the steam outlet and the  superheater;
temperature; composition of the gas; SO;> and SOj  con-
tent of the flue gases;  content of acetic acid and  aldehyde;
biological studies on the ash cooling  water; moisture
content of the flue gases; and  special analysis of the ash
including specific heat and calorific value of the ash.
The efficiency  of the refuse incinerating plant was 56. 7
percent.  For maintenance of purity  of the atmosphere,
the requirement is imposed on refuse incinerating plants
that the flue gas after  1000 fold dilution - as it is assumed
to be at the exit of the smokestack - must show only one-
tenth of the maximum  working site concentrations  tolera-
ted for acetic acid and formaldehyde.  The measured
corresponding values represented but fractions of  the
maximum permissible  emission values.

Translated from German.  STAUB, 23(3): 218-225,
March 1963.  6 refs.

A working group comprising 22 townships  was established
in the German Ruhr area to develop and implement mea-
sures for refuse removal.  Four possibilities of disposal
are listed: the deposition of refuse in  alternating layers
with soil, composting  of refuse, incineration combined
with heat utilization, and incineration without heat utiliza-
tion.  The advantages  and disadvantages of these methods
are discussed in detail, with special emphasis  on air
pollution by fly ash. Experience with a. composting plant
in Duisburg showed  that for odor removal air coolers  and
scrubbers had to be installed.  Finally a process was
adopted which used chlorine dioxide for decomposing
organic compounds. It is recommended that composting

In refuse incineration it is shown that there is a difficulty
in finding markets for the heat produced.  An example of
a large  incineration plant with heat utilization in Karnap
is given and it is emphasized that incinerators can be
used in  combination with peak power plants.  Experience
with a small incinerating plant without heat recovery is

Kraft, r7(8):391-395, Aug.  1965.

Several refuse research topics were discussed,  including
refuse incineration with heat utilization for steam genera-
tion.  A cost comparison of a refuse incineration plant
in Issy-les Moulineux which has  four furnaces "with  a
capacity of 17 tons/hr each, showed that income from
the sale of electric power and  steam exceeds the opera-
ting expense.  In Glasgow, Scotland, it was found that
the electricity generated in refuse combustion cannot be
sold in Great Britain on a. continuous basis.  Another
topic discussed was a central refuse disposal plant
installed as additional incineration units  in existing
power plants.  Such an installation is being operated in
Goldenberg, near  Cologne,  Germany.  The operating
capacity of this unit is 1, 026, 000 tons/year.  The plan-
ning and design for the  Goldenberg plant are illustrated
and discussed in detail,  including refuse transportation
from a wide area on compactor trucks  with removable
bodies, rubbish and scrap processing,  moving grate
incineration, and refuse storage  in surrounding mines.
The advantages of large central incineration plants  are
discussed.

DESIGN AND OPERATION OF A MS COMBUSTION CONE
PLANT WITH REFUSE.  [Aufbau und Wirkungsweise

Translated from German.  Aufbereitungs-Technik, No.
3, pp. 135-138,  1964.

The  design and operation of a MS combustion cone plant
including the crushing installation for refuse are des-
cribed.  The unsorted refuse is dumped by truck into a
refuse bin where it is dried. At the bottom of this bin,
a combined  discharging and crushing installation is pro-
vided which reduces the refuse to a desired size (pieces
whose edges are 40 cm long) and discharges the material
from the bin. By means of a steel plate conveyor  the
material is  fed into the combustion cone housing and
thrown on to the combustion cone grate.  With plants for
a. throughput of 1500 kg per hr of refuse, the combustion
cone has a maximum diameter  of approximately 3.2m
and rotates  with n speed of 30 to 40 cm per minute rela-
tive  to the maximum circumference.  The ignition of the
material is  effected by a Schoppe burner operated  option-
ally  with oil  or gas.  The design and control of the
blowers in the system, calculated  to prevent the emission
of odoriferous or harmful gases, is discussed and illus-
trated.

Several lectures presented at the Third Waste Technolo-
gical Colloguium "which considered the technological and
practical aspects of the process of "waste incineration
are summarized.   The lectures included the technical
basis of waste incineration, various incineration systems
and the  problems concerning fireproof materials, and
the experiences in  the Stuttgart incineration project. It
became apparent that the problem of selecting a suitable
incineration system is not yet solved,  especially for
medium sized plants which still face extensive develop-
ment and expansion.  Aspects discussed include the
ignitability of the refuse, transportation to the plant and
weighing, the refuse bin, handling of the fire,  removal
of the slag,  and selection of grates.  Legal requirements
for air pollution control are mentioned and some data
given -e.g. a limitation of 0. 4 mg/m^ of SO2 emission.

of the SO£-concentration in the  surroundings of a source.
Thus a suggestion is made as a basis for  discussion
with regard to an addition to the TAL - Techn. Anleitung

things  rules for minimum stack heights).  An  example

Using light from a mercury lamp,  quartz spectrographs
were used to analyze the light 1. 2 km and  about 4. 8 km
away.  Thus the absolute air permeability of a  3. 6 km
air space at 2 300 m altitude were  determined. Absorp-
tion increased strongly with decreasing wavelength.  At
shorter wavelengths, some constituent of the atmosphere
prevents sunlight  from penetrating the  atmosphere at
the short-wave  end of the  ozone absorption band.  Simi-
lar work elsewhere is discussed.   The results  indicate
that ozone must also be present below those atmospheric
layers that participate in the dispersion of sunlight.

PART.) [Micrometeorologie e inquinamento dell'aria.

£(5):133-141, May 1966.

General aspects of micrometeorological effects on air
pollution are discussed.  A research proposed to impede
theformation of smog in cities is presented. The method
consists of constructing a tube with convenient height
and placing it vertically in the polluted zone.  Then very
hot air is blown into the tube,  under very high pressure.
The hot air will rise  and  finally collide with the 20° C
70° C  stratum, go through it and ultimately expand above
the stratum and will again have a normal temperature
distribution.   The air cools,  descends and permeates
the 20° C - 70° C stratum and dilutes it.  The ascending
shock  tears and mixes the stratum, and the descending
air dilutes it.

Rend.   (Paris), Vol. 192,  p.  457-461, 1931.  4 refs.

Optical density is  computed for different wave lengths in
order to show that absorption of visible radiation by the
atmosphere is produced  by an ozone layer of 0. 0022 cm/
km air.  An increased absorption in the short wave
lengths  is probably due to the presence of oxygen.   The
calculated concentration of ozone required to produce
the observed absorption (or 4. 3 mg/100 m  air at 15° C)
is of the same order of magnitude as can be obtained by
chemical analysis.  If the atmosphere contained the
same proportion of ozone at all heights, the total density
of ozone in the earth's atmosphere would be 0. 18 mm.

ATMOSPHERIC POLLUTION CAUSED BY LARGE

Termotechnica, No. 14, Reprint, 1964.

Atmospheric interactions such as heat diffusion, which
play a role in the basic pollution of a residential area
are considered in a quantitative study for the compara-
tive evaluation of air pollution levels.  Calculations are
presented for the concentration,  at ground level and at
various heights, of a gaseous pollutant diffusing freely
in a still atmosphere.   The values obtained, from which
actual concentrations can be calculated, are those of
equilibrium pollution,  not assuming any special meteoro-
logical conditions  which can produce serious danger;
they provide a means of comparison for residential areas
of different extension and shape.  Several typical shapes
of areas are examined.  Pollution is proportional to the
total emission from a  square and inversely to the side.
The maximum level of pollution, near the ground,  tends
to be proportional to twice the thickness of the  diffusion
layer,  instead of to the side of the square.  The values
of the turbulent diffusion coefficients are discussed and
the dangers of low air turbulence in large towns are
emphasized.

Translated from Russian.   C.I.T.E.P. A. Documentary
Information Report No.  20, CI 207,  (No Date) (Supplement).

A method was developed for calculating the dispersion of
pollutants in the atmosphere.  The method considers that
pollutants emitted by smoke stacks are mixed with air
and then transported together with air.  The method is
based on the turbulence theory and uses the vertical
component of the turbulence exchange coefficient and its
variation with altitude.  Also the temperature distribu-
tion, settling rate of the pollutants,  and parameters of
the smoke stack are considered.  The method can also
be used to calculate,  for a given wind velocity and
meterological situation, the maximum concentration of

 case of temperature inversion and terrain irregulari-
 ties.  The distance from the source at which the pollu-

 results are in good agreement with  experimental data.

 MEASUREMENT OF GLOBAL RADIATION AS A CON-

 [Glovalstrahlmessungen als Beitrag zu lufthygienischen
 Problemen. ] Translated from German.  Gesundh. Ing.
 (Munich), 86_(2):54-60,  1965.  13 refs.

 "Global" radiation is the combined radiation impinging
 on the earth's surface  directly from the sun and diffusely
 from the sky.  In global radiation measurements in the
 Hamburg area considerable differences  in radiation "were
 observed between the stations on individual days.   On
 the average the urban and industrial district showed
 reductions in radiation as compared to the immediate
 vicinity of Hamburg, the level of which differed between
 summer and winter and with varying -weather conditions.
 These reductions in global radiation are attributed to
 urban and industrial air pollution and make possible  an
 indirect check on the pollution of the air.  In the
 interpretation of the statistical data the  complicated
 interaction of air pollution and meteorological para-
 meters is taken into account.  In conclusion attention is
 called to the economic aspects of the air pollution
 situation.

 G25-G32,  March 8, 1968.  20 refs.

 A method for calculating dispersion, plume rise,  and
 maximum ground level concentration of a gas issuing
 from a. stack is given. The method  is confined to hot
 gases and gas  quantities  in the range of 15 to 100 nm^
 per s.  Of the  dispersion equations considered,  that due
 to Sutton was chosen.  Values for the vertical and
 horizontal dispersion parameters as a. function of
 atmospheric stability are suggested, and the effect  of
 sampling time is  discussed.  Multiple regression cal-
 culations  were made for  all published data on plume
rise.  The best agreement was found with an equation
in which the plume rise was proportional to the three-
quarter power of the wind speed.  This means plume
rise was inserted in Button's dispersion equation.   The
necessary stack height is obtained from the resulting
equation for the maximum ground-level concentration.
With a view to very unfavorable atmospheric conditions,
it is suggested that this concentration be multiplied by
a factor  of  1.6, or the stack height by 2.  However, it
is possible  that in practice lower factors could be
justified, because the impression from publications is
that the concentration given by this factor of 1. 6 is sel-
dom reached and then only under special circumstances.
Remarks are given on the calculation of maximum
ground level concentrations from a. complex of stacks.

THE INFLUENCE OF CITIES ON THE WORLDWIDE
TEMPERATURE TREND.  [Der Stadteinfluss auf den
weltweiten Temperaturtrend. ] Translated from German.
Meteorologische Abhandlungen,  7£(4):l-65,  1967.  34
refs.

An attempt has been made to exclude the warning influence
of growing cities from the consideration of long period
temperature trends  of large areas of the world. One
method used for such  calculations was the comparison
between rural (non-influenced) and city series for  a
possibly long time by  computing the single temperature
differences  of these two types of weather stations.  Sixty-
seven of such pairs, spread over the world,  gave the
results of +0. 24° C  average city influence for the forty
year period 1901   10 to  1941    1950.  In another method
of calculation,  dividing the global temperature  t'rend into
two individual series,  comprising stations situated in
cities and in open country,  the temperature  trend of the
curve representing the cities is  warmer to the  same
degree as it was  calculated for the mean effect resulting
from the growth of cities.  Thirdly, a computation of
worldwide temperature trends since 1871-80 using only
non-influenced (rural) stations and some reduced city
stations gives a temperature curve confirming  previous
calculations.  Accordingly,  the temperature, after a
short rise,  has fallen about 0.2° C since 1871-80.  This
amount is 0. 4° C below the present value generally
accepted as valid.   Thus, the  worldwide warming trend
finally diminishes to a short episode  of two or three
decades and a value not higher than +0. 25° C,  and the
present temperature is the same as  eighty years ago.

nation of the content of soluble impurities in the samples
is accomplished by the spectral method.  The relatively
poor  study of the chemical composition  of gaseous micro-
components and aerosols of atmospheric air can be attri-
buted for the most part to the absence of satisfactory
analytical methods.   Solution of this type of problem
makes it possible to obtain additional information on the

on meteorological processes and also to clarify the prin-
cipal problems involved in the sanitary-hygiene state of
the atmosphere and its corrosive  activity.

Prumysl,  ,lj>(9):558-559,  1966.

The polarographic and  colorimetric methods for deter-
mining nitrogen oxides  are revised.   He  finds that im-
proper composition of the absorption solution is respon-
sible for the biased (systematically lower)  experimental
results; potassium nitrite,  formed if the gas is absorbed
in O. IN KOH solution containing  H2O2, decomposes in
acid medium during further operations.   He therefore
recommends using the H2O2 solution for absorption with
subsequent alkalization before the sample is boiled down.
The applicability and suitability of methods for deter-
mining NO2 which utilize the formation of azo dyes are
discussed.

THE MEASUREMENT OF NITROGEN DIOXIDE IN THE

Report 11/15,  Landesanstalt fur  Immissions - und Boden-

Germany.  19p.   13  refs.

Up to  the present time  there has  been no standard pro-
cess for determining nitrogen dioxide in the atmosphere.
The Saltzman process is suitable both for  discontinuous
and continuous recording measurements, according to
international experience to date.   The chemical reaction
mechanism which forms the basis of this process is,
however,  still so obscure that different interpretations
and calculations of the  research findings are made.
The behavior of gaseous nitrogen dioxide towards re-
action solution in comparison with the calibration of the
process with  sodium nitrate was investigated.   It was
found  that, contrary to the classical conceptions,  0. 5  M
of sodium nitrate are not equivalent to 1 M of NO2, nor,
contrary to Saltzman's view, are 0. 72 M,  but  1 M of NO2
corresponds to 1 M of  NO2 ions  from sodium  nitrate.
The calibration factor for a calibration function establish-
ed with  sodium nitrite thus has no value  different from 1,
contrary to previous conceptions.  After calculation of
the limit of detection and the reproducibility, the  dis-
turbing  influences of foreign substances were investigated,
with special attention to the behavior of NO-NO2 mixtures.

 It was found that SO2 is not usually present in the atmo-
 sphere in the free state but in the form of sulfuric acid
 and sulfates resulting from the reaction of SO2 with
 water and ammonia present in the air.  The atmosphere
 in each of the cities studied (London and Paris) contained
 sulfuric acid, but this represented only a small part of
 the total  sulfate in suspension.   The concentration of the
 free or mixed acid was determined by collecting samples
 on Whatman No. 1 filter paper.  One filter paper -was
 used for two determinations: half to determine the HZ
 SO^ content by pH titration and half -with cyanin chro-
 mate to determine the total sulfate content.  Conducto-
 metric and colorimetric methods were also used.  To
 measure  the conductivity,  samples collected on filter
 paper were immersed in a KC1 solution of known nor-
 mality, and the SO£ content was calculated from the
 conductivity measurements.

 METHODS OF MEASURING AIR POLLUTION.  MEAS-

 Fumi Polveri (Milan), 6(12):333-336, Dec. 1966.

 Polycyclic hydrocarbons, present in the air an an inte-
 gral part of the material in suspension, and volatile
 hydrocarbons present in  the gaseous state, -were inves-
 tigated as pollutants.  Polycyclic hydrocarbons can
 cause  cancer.   Work on the "anthracene index" and the
 "method of quinine sulfate" made it possible to define a
 simple index of the tar material, whether this index
 could or could not be related to the concentration of
 individual polycyclic hydrocarbons.  Good results for
 determining the  smoke content of tars are possible if
 contamination by other pollutants, such as lubricating
 oil, is avoided.  The quinine sulfate method can be cor-
 related with the  daily measurements of smoke/SOz being
 carried out in various locations.  Volatile hydrocarbon
 pollutants are becoming more prevalent in large cities
 due to automotive emissions.  The principle of the index
 of the  quinine sulfate method is described using fluro-
 metric measurements on the sample and on a  reference.

MEASUREMENT OF AIRBORNE DUST.  [Matning av

Conference and Advanced Training Institute (TKF), No.
2, p. 33-36, June 1964.
This paper summarizes various methods of measuring
airborne dusts.  The measurement of dust in flue  gases
is usually  limited  to determination of the amount of
dust per cubic meter of gas.  Using the Bacharach scale,
measurement is made with a. simple pump which is used
to suck the flue gas through a filter paper,  the degree of
blackness  being a measure of dust content.  Ringelmann
cards are  also used in determining the relative darkness
of smokes, whereby an observer compares differently
shaded  cards with  smoke.  Optical smoke detectors can
be used to measure dust by  light beam diffusion in flue
gases,  and filters  can be used to measure dust directly
in weight units.  Other types of apparatus for measuring
airborne dusts include  konimeters, electrostatic precipi-
tators,  thermal precipitators, tyndallometers and
impingers.  In the  measurement of dust fallout, two
types of samplers  can be used.  One utilizes collection
devices in the form of vessels, and the other utilizes
adhesive surfaces.  Various methods applied to the
measurement of particle  size  distribution are  enumera-
ted and include:  microscopic  measurements and statis-
tical analyses; tape projection where soot flakes are
collected on a tape and projected in appropriate appara-
tus; sedimentation; centrifuging; and screening.

In order to  study particles which are smaller than 1
micron in radius, ultramicroscopy is used.  In the
ultramicroscope,  particles are viewed in the suspended
state,  with  strong side illumination,  against a dark
background.  For particles which fall with a constant
velocity, the time of the fall is measured with a stop
watch and the equivalent spherical particle  size is
determined by the Stokes formula.  The results of mea-

of solid particles and fog are presented.

gas are absorbed, with the exception of CO2-  These
compounds are then desorbed by heating and oxidizing
on platinum wool.  In order to remove sulfur oxides and

passed through silver wool which by chemo-sorption
eliminates these compounds. Subsequently, the gas
passes through a gas washing bottle with Ba(OH)2 solu-
tion where the COj formed by combustion is absorbed.
Its  amount is determined by titration with oxalic acid.
The applicable range of concentrations suitable for this
method is 20 to 400 mg  C/Nm3,  with 3 percent relative

 In the  East German electrochemical industry it has be-
 come necessary to develop a method for the analysis of
 cadmium in air.  Dusts and aerosols containing Cd are
 collected on glass wool in a glass tube.  At 500 liter  of
air per hour the collecting time is one hour.  Subse-
quently the glass wool is boiled in nitric acid and the Cd
concentration is determined photometrically by the dithi-
ozone method.  This method was chosen because it is
insensitive to zinc and nickel.  A detailed discussion is
presented of analysis of error.  The lower threshold is
13 jtg Cd at the 99 percent level; the standard deviation
is 19 percent.

SO3 DETERMINATION IN DUST-LADEN AND DUST-

Translated from German. Erdoel Kohle (Hamburg),
20(8): 568-572, Aug. 1967.

An analytical method is described which allows an exact
determination of the SO$  content of dust-free as well as
dust-laden combustion gases.  The apparatus for dust-
free analysis is illustrated and two tables  are given
showing the analytical data obtained with the catalytic
temperature at 450 and 550° C, respectively, and an
asbestos layer at 75° C.  A third table shows the gas
temperatures at different catalytic temperatures and
gas flow velocities.  The condensation tube of the appara-
tus should contain at least 4-5 gm of asbestos in a 4-cm-
long layer and the catalytic temperature should be high
if correct 803 values are to be obtained.  For 803 deter-
mination in dust-laden combustion gases a modified
apparatus is illustrated.  The dust in the gas reacts
with the 303 (or the sulfuric acid) and if this dust reac-
tion is disregarded the result of the analysis becomes
incorrect, the error increasing with increasing amounts
of reactivity of dust.  In the analytical method described,
this dust reaction is taken into account and the SOg (vol.
%) in dust-free gas, dust-laden gas,  and fuel gas is
tabulated.  It is further shown that analytical difficulties
result if calcium oxide is present in the dust. The con-
ditions under which SO2 reacts with dust to produce
sulphate are indicated.

 Of all presently known methods, the biochemical  deter-
 mination of blood COHb  (carboxyhemoglobin) is the most
 specific indicator of exposure to CO.  The carboxyhemo-
 globin level shows a fairly close relationship with the
 CO concentration in the  air at the workplace, but the
 relationship between the signs  of poisoning and the COHb
 level is  not pronounced and varies with individuals.
 Still undecided is the question of how to determine expo-
 sure  to low CO concentrations  that play a role in  chronic
 poisoning.  New  information is  described concerning the
 clinical  picture of acute poisoning, particularly the
 changes in the CNS that manifest themselves as memory
 disturbances and disorders in neurohumoral control.
 It is much more  difficult to diagnose  chronic  CO poi-
 soning.  Although signs of CNS  and neurohumoral im-
 pairment after fairly long-term exposure to low CO
 concentrations were more frequent in entire groups of
 exposed workmen than among normal persons,  they
 were  not specific enough to detect chronic poisoning
 individual  cases.  In future research on CO poisoning
 we must concentrate our attention primarily on a final
 solution to the problem of chronic poisoning,  and on
 determining the specific toxic effects other than the
 anoxemic effect of the  combination of CO with the hemo-
 globin.   (Authors' summary)

multiple and partial correlation methods.   The results
indicate basic differences between the average incidence
of certain respiratory diseases in the groups examined.

A photometric method is described for the determination
of CO which is based on the absorption of the gas in an
alkaline solution of the silver compound of p_-sulfamino
benzoic acid.  The silver compound is reduced to metal-
lic  silver which remains in colloidal suspension.  The
extinction of this silver sol is measured.  Under the ex-
perimental  conditions described,  the extinction is pro-
portional to  CO levels in the range of 0. 001-0. 5 percent CO.
At wave lengths below 500 m/i,  extinction increases
rapidly. For this reason, it is useful to carry out meas-
urements at short wavelengths.  For example, sensitiv-
ity with a Zeiss filter S42 is almost twice that for S50.
Exact directions for the determination of CO are furnish-

AN ARRANGEMENT FOR CONTINUOUS RECORDING OF
DUST MEASUREMENTS BY THE CONTACT-ELECTRI-

German.  STAUB (Diisseldorf), 24(9): 359-363, Sept.
1964.  12 refs.

The structure and operation of a contact-electrification
dust measuring recorder is described. Using three
types of quartz dust, tests are made to provide calibra-
tion curves of known dust levels.  Discrepancies in the
results are attributed to the impact of the particles on
the electrical recording wire.

Comparative measurements were taken  of aerosols by
the Biometeorology Department of the Freiburg Office of
Meteorology,  using Effenberger's avigraph and an air
sampler used in America.  A difference is noted in dust
loads for lowlands  and mountains.   Comparison of the
two pieces of apparatus finds the photometer more objec-
tive than the avigraph, the pump output (0.43 m-Vsec)
of the air sampler  low, and the nozzle on  the avigraph
easily clogged.  The values obtained by both measuring
procedures are comparable.  The air sampler requires
use of filter paper  with very uniform thickness.

A tyndallograph for dust measurement is described.
This new optical apparatus  is discussed and compared
with others.  It features a high efficiency of the  servo
feedback mechanism,  elimination of the temperature
dependence, insensitivity toward  oscillations in the
supply voltages, and automatic adjustment of the noise
to the measuring speed. It was designed for routine
measuring of dust levels in the coal mining industry.

A novel, automatic dust sampler,  based on the membrane
filter principle, is described which is  suitable for con-
tinuous checking of dust levels.  A series of filters are
rotated in turn in the path  of the air intake.  Measure-
ment of air in a car-parking tunnel in Stuttgart leads to
the conclusion that maximum dust levels are found at
night (due to increased traffic  after ventilation is shut
off for the  night).

a telephone received with a thin brass plate attachment.
The microphone is placed in a vacuum chamber to accel-
erate the particles and to protect the microphone  against
outside noises.  Secondly,  the results of calibration of a

Performance of an optical measurement system for dust

by dust or condensate,  differences in temperature of
moisture  near the light transmitter or  receiver,  and by
the instability of the dust-laden air  being monitored.
Corrections of these conditions are discussed, leading
to the design of a prototype apparatus.   This apparatus

The problem of counting small particles is discussed,
with examples from several countries.  A well-defined
counting method may be preferred,  but it would be pre-
ferable to have a standardized method which will, under
specified conditions, reliably count all detectable par-
ticles.  Methods  should be selected for routine meas-
urements on the basis of the best possible correlation
between results and the hazard of sickness caused by
the dust.  A final choice is hardly possible as long as
there ie no  clear indication of which results of dust
monitoring  are the best indicators of health hazards.

The methods for determination of dust particle sizes
are discussed, followed by a mathematical description
of particle size distribution expected in a dust collec-
tor.  These observations are then related to the behav-
ior of inhaled aerosols and compared with previously
observed results.  Particles of 4 p. diameter have low
rates of diffusion and sedimentation; only 22. 7 percent
are calculated to be deposited in the alveoli and 14. 5
percent adhere to the bronchi during exhalation.  Parti-
cles of 0. 4 M diameter are  calculated to be 33. 3 percent
deposited in the alveoli.  Deposition in the bronchi and
bronchioles occurs with 50 percent deposition during
inhalation of 5 M diameter particles,  and 50 percent
deposition during exhalation of 2. 12 it. diameter parti-
cles.  These theoretical  calculations  are  compared with
data from reported autopsies.  Retention curves are
calculated.  In conclusion,  gravimetric dust sampling

 refs.

 Evaluation of dust samples in the coal mining region of
 West Germany, by means of 54 "BAT" brand fine dust
 filter instruments,  is reported.  The instruments,  used
 for the determination  of quartz in mine dusts,  are equip-
 ped with a cyclone for the preliminary separation of dust
 particle sizes not entering the lungs.  Particle size dis-
 tribution measurements are described graphically,  re-
 presenting tests of coal,  slate,  and quartz dusts.  Slate
 dusts were used for investigations on the effect of an
 aspirated air volume of 3-15 m-^/hr on the degree of
 filter transmissivity; the latter can be  set at a certain
 value by applying a  definite volume of aspirated  air,
 thus simulating the  retention of dust in the lungs.  The
 effect of different air intakes on the concentration and
 particle distribution of fine dust, and the effect of total
 dust concentration on transmissivity,  also are documen-
 ted.  Gravimetric and routine photometric comparison
 measurements were carried out in 8 different mines,
 using the "BAT" fine dust filter-instrument, the  "Goth"
 total dust filter instrument,  a Tyndalloscope, and a
 mining konimeter.   Differences  of the "BAT" instrument
 results, shown  graphically,  were apparent primarily in
 the measurement of fine dust concentrations.

Comparative data are reported for the silica gel-method
and the TCM-method, the  two most commonly used
methods for determining SO£.  The accuracy of the
methods was established with a pure SOj-air mixture.
Both methods give  similar  results within the range of
probable error.  Agreement with atmospheric measure-
ments taken in Essen was also statistically satisfactory.
Reproducibility of the results, for levels between 0, 05
and 1. 0 mg. SO2/m-*, ranges from 4 to 8 percent. The
relative limits of detection and optimum range of meas-
urement,  based on standard conditions for both methods,
also do not differ.  Both methods can detect as little as
0. 01 mg.  SO2/m3,  Levels greater than 0. 03 mg. SO2/
m3 are determined with a standard deviation of about
5 percent.  Sampling times of 10-60 minutes can be used.

POLAR OGRAPHIC-COULOMETRIC ANALYZERS FOR
TRACE CONCENTRATIONS OF SOz.  [Polarograficko-
coulometricke analyzatory na stopove koncentrace SO2-J
Translated from Czech.  No reference, 6p. 3 refs.

A sensitive polarographic-coulometric method for the
measurement of trace concentrations of SO2 in the atmo-
sphere has been worked out and on its principle a con-
tinuous analyzer has been constructed, characterized
by simplicity,  portability, and operational dependability.
The method is based on a  continuous coulometric meas-
urement of the concentration of iodine ions, which form
in the course of the known reaction between SO2 and
elementary iodine.  The electrolytic current flowing
through the solution corresponds to theoretical assump-
tions; it is a correct measure of the  SO2 concentration
in the gas  supplied, if the solution flows through the
electrolytic vessel slowly enough in order not to carry
away a substantial quantity of the formed iodine ions
before they can undergo electrochemical oxidation on
the indication electrode.   The principal advantage of
these instruments, aside from their  high sensitivity and
simplicity, is the circumstance that  SO2 concentration
can be expressed in terms of the magnitude of electric
current (with a known gas flow) without the necessity of
gauging them with gases of a known SO2 concentration.

STOCHASTIC APPROXIMATION OF THE LARGEST
INEFFECTIVE DOSE.  [Stochastische Approximation
der grcissten unwirksamen Dosis.]  Translated from
German. Metrika,  U_(2): 106-114, 1966.  4 refs.

In a theoretical statistical discussion of a well-known
dosage-response model,  a sequential procedure for
finding a reasonable lower limit for a dosage with a
small probability of response is given.  The more gen-
eral problem of finding a dosage with arbitrary given
probability of response is solved by the procedure of
Robbins and Monro which, however,  contains no stopping
rule. It is of considerable practical value to have a
procedure with a stopping rule for this important special
case.  Some heuristic points of view to choose an effec-
tive procedure are considered.  The statistical reason-
ing used is illustrated by equations and by a flow-dia-
gram indicating, among other features, that the dose
applied in the last case yielding a response is never
exceeded, and that a new lower dose is applied until
either a response is achieved or no response is achieved
"i" consecutive  times.  The goal is to accumulate  "n"
failures at one and the same dose.

OBSERVATIONS ON ATMOSPHERIC POLLUTION FROM
SUSPENDED DUST BY MEANS OF AN AUTOMATIC

da pulviscolo sospeso medinate campionatore automatico.J
Translated from Italian.  Giornale di Igiene e Medicina
Preventiva, Vol. 1, p. 57-68, I960.  8  refs.

The functional  details of an automatic suspended dust
sampler are described, and results obtained with an
apparatus  of this type over a two year period are re-
ported.  In the sampler, air which is aspired by a suit-
able pump, driven by an electric motor,  is conveyed
across a strip  of Whatman #4 filter paper wound on two
bobbins located at the top and the valley, respectively,
of a circular filter with an internal diameter of 25. 4
mm.   A series of electric circuits regulated by a timing
device provides cyclic automatism for the sampling, by
controlling the pump, and the progress of the paper strip.
Collected samples are estimated by optical means and
results expressed as optical density units per cm^ per
m .  By this method it was possible to observe some
characteristic  variations of  air pollution caused by sus-
pended matter  in a residential and in an industrial dis-
trict  of Genoa.  Marked differences of pollution were
noted between  samplings in an industrial district and in
a residential district.  Only in the residential district
was it possible to observe an increase in pollution values
during the winter months.   The presence of a maximum
of high dust values from 7 to 11 in the morning was con-
firmed.

an alternating light photometer which the Duisburg
Copper Smelting Plant has been successfully using. The
concentration measurements made with this home-made
photometer are based on the fact that gases reveal a
radiation absorption in certain wave length ranges which
depends on the gas concentration.  By measuring this
radiation absorption at a certain wave length or in a
certain wave length range,  the percentage of the harm-
ful gas after  calibration of the photometer with gas-air
mixtures of varying concentrations  can be indicated
directly.

processes for desulphurization of hot flue gases  are
being preferred. According to the Reinluftprocess a

•with a sulphuric acid plant, a. Glaus oven plant, and an
oil burning installation.  Another plant of this type with
et capacity of 33, 000 Nm3/h is being erected in con-
nection with ct pitcoal power station in order to test the
process with different kinds of furnaces.   At the same
power station another desulphurization process is being
tested by blowing lime or dolomite into the boiler
(Wickert process).  Finally at a  coal-fired power station
another desulphurization plant has to be erected using
absorption of sulphur dioxide on  wet lignite coal  filters

AUTOMOBILE EXHAUST GASES AND THEIR DETOXI-

CO reduction by idling regulation according to the limits
set by a VDI (Verein Deutscher Ingenieure Society of
German Engineers) Directive •will make it possible  to
reach an immediate solution that is optimal for European
conditions, provided cheap measuring instruments are
available.  Because of the probable simultaneous de-
crease in the aldehyde component, the  odor might also
become somewhat less  at the same time.  If the USA
should throttle German exports by stricter detoxification
regulations with respect to hydrocarbons, under some
circumstances still more would have to be done.  Cer-
tainly further work will  be done in the Federal Republic
on the motor side,  including among other things an air
blast at the exhaust valve.  In cases where this does
not suffice use will again be made of the reliable catalyst,
perhaps with the very same additional air blast at the
valve or with a self-regulating exhaust gas fresh air
ejector.  The catalyst,  as  an optional pure exhaust
catalyst with bypass, might represent a future  solution.

The extent of sulfur dioxide emissions in various
branches of industry is given,  and it is  shown that the
power industry affects these emissions.  Since sulphur
removal from  fuel is technically difficult and expensive,
the desulphurization of flue gas at main emission points
is the only solution to the  problem.  Known methods for
flue gas desulphurization are described and compared,
and subsequently some of  the processes tested in pilot

 SULFUR DIOXIDE GAS IN EXHAUST SMOKE, ITS RE-
 MOVAL, RECOVERY AND UTILIZATION BY WET
 PROCESSES.  Translated from Japanese. Japan Analyst
 (Tokyo),  1_5_(8):872-881, Aug.  1966.

 Thirteen wet absorption processes for the removal of
 SO2 in industrial exhaust are reviewed and evaluated in
 terms of efficiency,  economy  and recovery by-products.
 Emphasis is placed on recovering SO2 in various useful
 compound forms such as ammonium sulfate and gyosum.
 A disadvantage of wet processes  is  that the tempe. ature
 of exhaust gas decreases, resulting in the decrease of
 thermal bouyancy and exhaust velocity.  The necessary
 booster  power to make up for  the difference in exhaust
 velocity is calculated to be 25.7 KW, assuming the
 temperature decrease of 80° C and certain typical con-
 ditions such as the composition of exhaust gas.  Using
 the same assumed data as above, the effective height of
 a. 50 m smoke  stack becomes  142.12 m.  Sulton's
 equations give the maximum SO£ concentration between
 2360 m and 15,840 m depending on the air temperature
 gradient.  From these calculations, it is concluded
 that wet processes can be used profitably in controlling
 air pollution if they are combined with appropriate
 corrective measures.

PROBLEMS OF REMOVAL OF FLUE GAS FROM GAS
FIRES.  [Probleme der Abgasabfuhrung von Gasfeuer-
statten.J  Translated from German. Gas Erdgas GWF,
H>7(33):922-932, Aug.  1966.  4refs.

Methods of removing flue gases from several types of
home gas furnaces are described.  The problems to
which each single method gives rise are thoroughly de-
scribed in a  discussion section at the end of the article.
Specifically, the paper mentions conventional chimneys,
used either  exclusively with gas heaters or with several
heaters at once,  ducts which lead straight from heaters
through outer walls to the outside, community ducts,
and closed or so-called "se-ducts".  Several cut-off
valves (dampers) to isolate given  units from the main
removal duct are discussed, among them thermostatical-
ly controlled cut-off valves and mechanical ones, the
latter being either fully automatic or gas-pressure acti-
vated,  electrically controlled or gas-pressure operated.
In conjunction with the discussion  of conventional chim-
neys, the problem of "wet" chimneys is emphasized.

BEHAVIOR OF NITRIC OXIDE DURING ELECTRO-
STATIC GAS PURIFICATION,  [tjber das Verhalten des
Stickstoffmonoxids bei der elektrostatischen Gasreini-
gung.] Translated from German.  Brennstoff-Chemie,
47(9):273-274,  Sept.  1966.

The effects of field intensities,  ionizing-electrode dia-
meters,  duration of the gas in the electrostatic purifier,
concentrations of nitric oxide in the gas,  and the pres-
ence of unsaturated compounds upon the decomposition
of nitric  oxide were measured by means of an experi-
mental electro-filter situated in a coke-oven plant.
Within the range of 0 to 3. 8 kv/cm, the quantities of
NO decline with increasing field intensity, this decline
amounting to only about 10 to 20  percent at field strengths
of 2 to 3  kv/cm which are  commonly used in coke-oven
installations.  Industrial-economic considerations, how-
ever, place a limit on the  extent to which voltages can
be increased in practice.  The period during which the
gases remain in the filter  is a factor in the reduction
of NO content,  but a doubling of this period from 6 to
12 seconds results in a maximum increase in the de-
composition rate of only 25 percent.   The reduction in
NO tends first to decline and then to increase as the
diameter of the ionizing electrode is increased. The
most effective factor in the reduction of NO contents is
the addition of unsaturated compounds; thus the addition
of 2.5 ml cyclopentadiene  per cu/m of gas increases
the loss  of NO by  a factor  of 4 under certain experimen-
tal conditions.  The experiments show that current com-
mercial  coke-oven practice results in reductions of about
20 percent in NO content,  and that an increase in the
field strengths together with a rise in the unsaturated-
compound contents can effect reductions of 50-60 percent.

Ventilation of automobile exhaust from tunnels is dis-
cussed.  The permitted level of CO concentration is
0.025 percent.  The ventilation rate of a tunnel is de-
fined as the ratio of the amount of harmful gases to the
permitted level of each of them.  Poor visibility is a
problem in tunnels due to  smog.  The tolerated concen-
tration of this substance is 30-50 percent.  Equations
are given to define visibility.  Three types of ventilation
systems are discussed: longitudinal, transverse,  and
semi-transverse.  The first  semi-transverse system
in Japan was that of the TENNOZAN tunnel. The  system
is discussed and explained with a cross-sectional dia-
gram and a. rough sketch of the whole tunnel.

Electronmicroscopic photographs of thoron daughters
from thorium nitrate corrected by a thermal precipi-
tator, and an investigation of the relation between
filtering efficiency and the number of sheets  of filter
paper used showed that the particle diameter of the
thoron daughter aerosols was very small  and fairly
uniform  in an examination of various kinds of dust
filters using radioactive  solid aerosols of the thoron
daughters.  Thoron and thoron daughters  generated
from thorium nitrate in a flask were led through a
polyethylene tank to the dust filter to be tested.  Several
kinds of  dust filters were tested for  their  filtering ef-
ficiency  by measuring the radioactivity of aerosols be-
fore and after filtration using a membrane.  The filter-
ing efficiency was generally low in most kinds of dust
filters -which usually showed high filtering efficiency
for ordinary dust particles,  due to the small particle
size of the radioactive aerosol.  Fiber glass filters for
use in measurement of dust concentrations and A.C.G.
(asbestos, cellulose, fiber glass) filters  showed over
99 percent filtering efficiency even for radioactive
aerosols.

zer Archiv, 31(4): 119-126, April 1965.   7 refs.

An oil furnace well built and maintained should cause no
intolerable air pollution.   Soot and a smell of oil will
occur only in case of improper adjustment  or perhaps
in starting up.  In the latter case an inadequate means
of ignition,  too low carburetor temperature,  or ex-
cessive cooling of the flame may  be the cause.  Some
methods of combating this difficulty are described here
(beginning injection of fuel only after  an adequate oil
pressure is achieved in the pressure  atomizer burner;
as nearly continuous operation as possible for evapo-
rator furnaces; use of higher pressure for the air of
combustion).  In  pressure atomizer burners such dif-
ficulties can usually be traced to defective nozzler or to
poor combustion  from other causes.  Installations which
give rise to complaints must therefore be overhauled
and replaced if necessary.  Determination of unburned
hydrocarbons is more difficult.  Research in this field
concerns itself among other things with the following
problems:  studies of the emission of unburned hydro-
carbons during the starting period; improved mixing of
air and oil mists; influence of systems for recirculating
smoke gases; ultrasonic and airfoam atomizer burners;
electrostatic oil atomizing; total evaporation of the fuel
in the vaporizer burner; and speed of combustion.

A review is presented of the corrosiveness of soot
particles,  conventional protection methods,  the pro-
cess of soot formation, the formation of sulfuric  acid,
adsorption by soot particles, suppression of floe  for-
mation,  and practical  tests conducted at Tekniska Hog-
skolan in Stockholm.   An improvement is advanced; an
increase of the boiler  water temperature when heating
with heavy oils appears to be justified.  The increase
should be up to 150° C for the adsorption of aggressive
substances on soot particles to  be adequately suppress-
ed.  The proposed increase  should result in reduced
damage to  protective coatings,  automobile lacquers,
ladies'  stockings, and clothing where aggressive  soot
floes easily produce point attacks.  In addition the
corrosion on the  fireside surfaces  of the heating boilers
will  be  substantially reduced.

The method for the desulfurization of flue gases accord-
ing to the dolomite procedure was investigated with the
help of a 175 t/hr oil boiler.  The factor that was deci-
sive for desulfurization was the temperature that pre-
vailed in the boiler at the place where the desulfurization
material is  inserted.  The effect of the distribution, the
duration of time (in the boiler), the effect of the catalyst
and of the volume of the  material  to be used were of
secondary importance.  It is understood on the basis of
the description of the experimental results, that these
results for the time being apply only to the experimental
boiler. Some of  the basic problems  could not be resolved
and new basic problems  arose; these problems must be
answered for the purpose of planning and giving a guar-
antee in connection with  the erection of a desulfurization
installation.  Additional  series of experiments are nec-
essary before the method is ready for actual operation.

 THE EVOLUTION OF THE TECHNOLOGY OF DUST
 REMOVAL.  Translated from German. STAUB, 21(9):
 382-390, Sept. 1961. 43refs.

 Although the problems of dust nuisance are very old,
 it has only been possible to speak of an actual dust-
 collecting technology in the last 70 years.   The  basic
 patents for filter dust collection and cyclone dust col-
 lection were announced in 1886 and for  electrical dust
 collection in 1908.  Between  the first proposals and
 final introduction of the methods  into practice there was
 a gap of between 20 and 40 years. The processes in
 dust collection are in many cases of a technical flow
 nature and hence can be  treated by technical flow
 methods.   This is shown particularly for the case of
 the development of the cyclone collector.   On the basis
 of newer knowledge, a systematology is proposed for
 the cyclone collector using certain characteristic values.

 LUTANTS.  [Die katalytische Nachverbrennung von

 German.  Die Technik, 20(b): 395-400, June 1965.

 Newly developed all-metal catalysts are discussed
 which are designed on the basis of the building block
 assembly system;  in practice, they achieve an average
 running time of  25, 000-35, 000 working hours. A
 catalyst, which  speeds up a reaction because  of its
 presence, without itself participating in the reaction,
 reduces the decomposition temperature during com-
 bustion.  A reaction temperature of 250-350° C was
 achieved with all-metal catalysts developed for catalytic
 exhaust gas purification.  The cold exhaust gases flow
 through a heat exchanger and are preheated.  Then they
 are heated by means of oil burners, gas burners, or
 electrical heating  elements until they reach the catalytic
 reaction temperature. A fan then moves the exhaust
 gases to the catalyst where the irritants are oxidized.
 The heat released during catalytic combustion is large-
 ly recovered in  the heat exchanger and it is used for
 heating the cold exhaust gases as combustion  here is
 exothermal.  At a reaction temperature  of about 250-
 350° C, all combustible components are oxidized in the
 exhaust gas.   As a result of the temperature increase in
 the exhaust gas  in the catalyst,  the positive heat change
 of this reaction  can be measured which gives  a. figure
 directly proportional to the irritant concentration.   The
 catalytic exhaust gas purification unit thus serves as a
 measurement  instrument for the concentration of the
 exhaust gas.   A measurement system used for continual
 surveillance is diagrammed.  Applications of catalytic
 afterburning are discussed in relation to the following:
 drying and hardening processes, phthalic acid and maleic
 acid anhydride production, nitric acid production, NO/
 NO^ reduction.

DIESEL EXHAUST GASES: INVESTIGATION WITH PRO-
POSALS FOR ACTION.  [Dieselavgaser:  Utredning med
forslag till atgarder. ]  Translated from Swedish.  Stock-
holm,  Sept.  1967,  74p.  27refs.

Diesel exhaust emissions and methods of  controlling
these emissions in Sweden are reviewed.   The diesel
engine differs from the gasoline engine in several re-
spects, 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 ignition 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 serious air polluters.  Poor  maintenance of
the engine 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 pro-
posed regulation of diesel  exhaust emissions are dis-
cussed.

REMOVER OF SULPHUR DIOXIDE GAS.  Translated
from  Japanese.  5p. ,  1967.

A method for removal and absorption of sulphur dioxide,
which is applicable to  other gaseous  substances,  is de-
scribed.  This equipment processes  sulphur dioxide gas,
discharged by a smoke duct with water or a weak alkali
solution, fixing the sulphur dioxide gas in burned and
discharged gas.  The processing water or fluid is a thin
membrane through which burned and discharged gas must
pass upon leaving. Effective absorption is achieved by
reducing the current speed of gas within the equipment.
Designs permit continual renewal of  air liquid  contact
and control of loss of gas pressure.  With this  system,
SO^ can be almost completely removed and large quan-
tities of gas can be processed at a low cost.

AFTERBURNING. [Apparate und Anlagen zur katalyti-

Chemie-Ingenieurwesen-Technik, 37/9):905-912,  1965.

The catalytic combustion of waste gases  and vapors has
the purpose of keeping the air clean and producing heat
energy or infrared radiation.  The simplest types of
catalysts are those used in diesel and Otto engines.  For
burning industrial waste gases the catalysts become
more complex.  Three different types most widely used
are catalysts whose  active component is  thinly spread
out over chromium-nickel-steel substrates, over ce-
ramic bars, and over the inner and outer surfaces of
small cylindrical ceramic bodies  of various sizes. The
temperature of the waste gas is important for efficient
catalytic afterburning.  The  efficiency may increase
rather steeply by raising the temperature by only a few
degrees.  The influences of the flow rate of the gas
through the afterburner on the efficiency is discussed in
detail.  The useful life and possibilities for regeneration
of the catalysts is discussed.  The costs of a catalytic
afterburning system are determined not only  by the
catalyst but also  by the requirement of a heat exchange
system or of preheating the waste gas.  This applies
especially to waste gases of  less than 1000 kcal/m^.
An example for such a system as well as for  a  catalytic
infrared radiator are  briefly described.

FUNDAMENTALS OF CATALYTIC AFTERBURNING.
[Grundlagen der katalytischen Nachverbrennung.]  Trans-

904, Sept. 1965.  27 refs.

Catalytic afterburning proved itself as suitable for the
removal of objectionable and harmful impurities from
industrial exhaust gases in a number of instances. The
length  of the catalyst stretch that must be passed by the
exhaust gases to attain a certain degree of conversion
(degree of oxidation) can be characterized in terms of
the 'length of a conversion unit' provided that the re-
action  is first-order and proceeds approximately iso-
thermally.  This term encompasses  in a rational
manner the  effects of reaction rate and catalyst activity
(including catalyst porosity and internal surface),  gas
flowthrough, longitudinal mixing, and material transfer
between gas flow and catalyst surface.  The material
transfer imposes minimum lengths for a. conversion
unit; these were explained in more detail for a  particle
layer and for insert catalysts with perpendicular flow
within  tube clusters.  If the conditions deviate strongly
from formal kinetics of the first order, this treatment
no longer remains applicable, as has been shown on the
example of an autocatalytic oxidation of CO on a Pt
carrier catalyst.  At higher concentrations of  components
to be oxidized, increasing temperature profiles develop
along the catalyst layer:  these were discussed under the
assumption that the  operation is  adiabatic.   As the heat
generation and the activation  energy  of the reaction in-
crease, more and more of the total conversion will
crowd  into a relatively short layer cross section with a
steep temperature gradient.  Under certain conditions,
thermal instabilities may occur here for the catalyst.
These  lead to  the formation of 'combustion zones, '
which are stationary only at a characteristic 'combustion
rate' and gas flow rate within the catalyst layer.  Curved
combustion zones  are able to  adapt themselves within
•wide ranges to changing gas flow rate by expansion or
shrinkage.  Concentration profiles measured in a. com-
bustion zone created with a butane/oxygen mixture in-
dicate  the intensity of the reaction in the steep tempera-
ture rise  range.  Combustion zones could be created at
relatively small temperature  gradients and relatively
low intake temperatures in the autocatalytic oxidation
of CO on Pt catalysts.  (Author's summary)

 A wet process gas absorber developed at the Kanagawa-
 Ken Industrial Experiment Laboratory was tested to de-
 termine its efficiency in eliminating sulfur dioxide. Its
 compact size, minimum pressure loss and absorption
 speed, are described favorably.  This absorber can also
 be used as a dust collector, or as a cooling tower as
 well as for desulfurization. Detailed test results are
 not given.  The provision of several thin mesh screens
 inside the absorption tower increased liquid surface
 contact with the gas  and permitted the  comparatively
 small equipment to handle large quantities of gas.  The
 relationships between the height of the liquid screen
 and the liquid/gas ratio are calculated to show that by
 increasing the number of screens,  the concentration of
 SO2 gas can be reduced to the desired  level.  Further
 tests were then carried out at a steel factory in Kawasa-
 ki,  Japan, and the results tabulated.  4,200 m3/hr (at
 40° C) exhaust gas with a liquid/gas ratio of 0.78 show-

The problem of  improving the automobile exhaust gas
composition is discussed on the  basis of literature and
original experiments.  Various sources of undesirable
exhaust gas components are listed and discussed. Meas-
ures for improving the exhaust gas composition such as
traffic flow control and engine modifications are analyzed
in detail.  Changes in compression ratio, setting of idling
speed for lean mixture,  cutting of fuel supply during
braking, heating of engine for cold starts,  etc.  are some
of the modifications discussed.   A lower compression
ratio in diesel engines and ci limited fuel injection would
improve diesel exhaust gases. Also electric drives are
covered.  It is concluded that Diesel and Otto engine ex-
haust can be  substantially improved if a somewhat  lower
performance is  accepted.  A prerequisite for such meas-
ures would be legislation binding for all manufacturers.
A unified European solution  is recommended.

Automobile engines idling during change of gear, braking,
or standing operate in a. regime  during which the toxicity
of exhaust  gases increases  substantially. This is due to
the fuel rich mixture yielding a high percentage of incom-
plete combustion products.   This phenomenon has been
studied and an air-fuel ratio regulator was developed
which is mounted in the  intake line and starts operation
automatically when the engine  idles.  Gas samples with
and without the device were analyzed under various opera-
ting conditions.  Without the device carbon monoxide con-
tents ranged from 3. 2 to 7.  8 percent while with use of

THEORY AND PRACTICE OF DUST COLLECTION BY
MEANS OF CLOTH FILTERS.  Translated from German.
STAUB (Diisseldorf), 2J.(9):437-443, Sept. 1961.  11 refs.

The problem of  correctly classifying the various types
of cloth dust filters available for industrial use is dis-
cussed.  Emphasis is placed on filtering characteristics
in relation to the nature of the dust layer which remains
on the cloth during filtering.  Two instruments most
suitable for measurement under test conditions are de-
scribed: the dust mass probe and the velocity probe.
Formulas, graphs, and tables are given to demonstrate
the methods used to evaluate different materials and
circumstances best suited for specific industrial appli-
cations.

ON PRACTICAL USE OF THE CENTRIFUGAL DUST
SEPARATOR.  Translated from German. STAUB (Dusse-
Idorf), ^3_(11):509-512, Nov.  1963.  4 refs.

A centrifugal dust separator of 200 mm diameter was
tested for coal and stone dusts.  The separator had been
previously developed for a capacity of  350 m-Vhr.  The
problem of increasing the capacity of such a unit is dis-
cussed by increasing the size of a single unit or by
arranging several units  in a multi-cell installation.
Pilot units of 500 mm and 1000 mm diameter were test-
ed and up-scaling of methods were theoretically develop-
ed.  Development of a large multicell unit with a capac-
ity  of 30,000 m-^/hr for  dust collection in a,  tar-macadam
plant is also discussed.

THE CENTRIFUGAL DUST SEPARATOR.  Translated
from German.  STAUB (Diisseldorf), 23(4):228-230, April
1963.  1 ref.

The principle of a newly developed dust separator is
explained.  The operation of the separator is based on a
vortex generated by countercurrent gas injection into the
raw gas moving upwards  in a vertical tube. To rein-
force the separating effect a drop shaped bluff body is
placed in the tube.  Separation efficiencies for  different
particle size fractions were determined in a 200 mm
diameter separator.  Tests with larger units (300-1000
mm diam.) have also been conducted.  The installation
of a separator into the smoke stack of a power  plant
(2-2.5 m diam.) is being planned.

PHYSICAL BASIS AND PRINCIPLES OF THE CENTRI-
FUGAL DUST SEPARATOR.  Translated from German.
STAUB, (Dvisseldorf), 23(11):491-501, Nov. 1963. 8 refs.

The physical principle of a new centrifugal dust separator
is described in detail.  First the theory of rotational and
potential flows  including source and sink flows is analyzed.
Then the theory of the separator is derived.  The separa-
tor is based on the principle that the raw gas flows up-
wards in a vertical tube and a secondary gas  stream is
injected countercurrently.  The latter imparts a rotating
motion which effects separation of the dust.  This prin-
ciple is compared with that of a conventional  cyclone,
and the  advantages are evaluated.  The vortex source
effective in the centrifugal dust separator  is responsible
for its higher efficiency as compared with a cyclone work-
ing on the basis of an eddy sink.

The development of a pilot model of a centrifugal dust

on the principle that the gas containing the dust flows up-
wards in a vertical tube and a secondary air jet is in-
jected at a certain angle countercurrently into the  gas.
The raw gas  inlet design, the jet angle and configuration,
the pressure ratios, the possibility of using more  than
one jet, the efflux baffle design, prerotation of raw gas
and other parameters affecting  the separation rate and
efficiency were studied. Also upscaling of units is treat-

The problem of  soot pollution in Stockholm is discussed.
Despite extensive research in combustion technology,
approximately 15 tons of soot settle over Stockholm every
day.  Aspect of  the problem,  such as building codes,
effect of oil burning, size of flue area, height of smoke-
stacks are mentioned.  The importance of dust separators
is stressed. A  plea is made for increased attention,
through regulatory means, if necessary, to the improve-
ment of fuel combustion so as to reduce by at least 75
percent the amount of soot emitted into the atmosphere
at present. A system of continuous soot removal from
furnace surfaces by water scrubbing recommended by
some manufacturers,  is rejected as  leading to damage
by water pollution.

 POLLUTION ON THE INDOOR ENVIRONMENT AND
 MEASURES  TO PREVENT POLLUTION.  Translated

 31.  Jan.  1967.  24 refs.

 Indoor and outdoor pollution -were compared to determine
 the various capacities of air cleaning and ventilation
 equipment for reducing the effects of atmospheric pol-
 lution on the indoor environment.  The results were used
 to establish  the standards for  the installation of air  clean-
 ing equipment in a building.   The building selected was
 provided with two air filters "with high dust efficiencies.
 The following items were determined: 1.  Change in out-
 door air pollution with time; 2.  Change in indoor air pol-
 lution with time; 3.  Air  quantity of ventilation system;
 4.  Quantity of air infiltrating into the building; 5.  Air
 pollution upstream and downstream of air filters; 6.
 Changes in the number of people in the room;  and 7.
 State of smoking in the room.  The results were  analyzed
 and compared with theoretically calculated data concern-
 ing the efficiency of air  cleaning equipment.  In order to
 know the state of particles floating in the air,  the follow-
 ing measurements were necessary:  1.  concentration of
 particles; 2. distribution of particle size; 3.   physio-
 chemical composition; and 4.  change in particle concen-
 tration with  time and space.  Two methods were  applied
 for dust concentration measurements: the discoloration
 method, measuring the optical density of the filter paper,
 and the weight method, measuring the relationship be-
 tween optical density and the weight  density of  the dust.
 The dust removing efficiencies of the installed air filters
 were calculated from their upstream and downstream
 dust concentrations. From the data obtained,  the dust
 quantity generated in a room was calculated.

 Translated from German.  STAUB,  2.3(11): 530-535, Nov.

 Cloth filter installations for dust removal from waste
 gases from a hotblast cupola furnace with recuperator,
 two electric reduction furnaces, and a 60-ton electric
 smelting furnace are described in detail.  Cupolafur-
 naces and electric furnaces  emit a very find  dust which
 in all cases must be designated as a nuisance. In the
 dry collection of these  dusts, very high efficiency col-
 lectors are necessary.  Recently cloth filters have been
 used in Germany with success.  With residual dust con-
 tents which lie in the order of magnitude of mg per m  ,
 the waste gas plumes are no longer visible.  In many
 cases,  however, the high "waste temperatures must be
 reduced by connecting coolers in series.

A dry electro-precipitator for cleaning cooled combustion
gases from a. hotblast cupola furnace,  after passage
through the recuperator, is described.  It removes about
94 percent of the dust with a resulting dust content of
about 60 mg per m3.  The relationship between the  quan-
tity of injected water and the efficiency of dust removal
ind electrical dust resistivity are reported.   For optimal
efficiency in cleaning off the precipitation plates, a pause
length of 15 minutes between rapping periods was chosen
upon investigation.  Interim results obtained  on a new
type of electroprecipitator,  in which the electrodes are
situated perpendicular to the flow of gas, are also re-
ported.

Planning measures are the prime requirement for avoid-
ing setbacks to agriculture due to air pollution now and
in the future. These measures concern the location  of
industrial sites with regard to agriculture areas, con-
sideration of meteorological conditions, the surface  con-
figuration, the height of chimneys and the concentration
of industries. In addition, further research must be
encouraged  with regard to the sources of impurities  and
measures to prevent or restrict air pollution.  Uniform
methods for measuring the levels and for setting limits
to air pollution must be established.  The agricultural
industry must do more agricultural research and must
study the results.  The minimum requirements for air
purity and sunlight for  maintenance of reasonable
agricultural production can thus be formulated.   The
agricultural community roust be considered and consulted
as an important participant in discussions.

REMOVING SULFUR FROM FLUE GAS: SIGNIFICANCE

21 refs.

A critical survey of the basic processes for the removal
of SO2 is presented,  with emphasis on economic feasi-
bility.  Additive and wet scrubbing procedures are gen-
erally unsuitable.  Of dry absorption and adsorption pro-
cedures, the latter have more successful prospects in
relation to technical applicability and economic feasi-
bility.  Of  the absorbents,  only activated charcoal is
suitable at the present time, in spite of its  high cost.
The development of a new process has placed the appli-
cation of activated  charcoal on an economically feasible
basis.  The need for  activated charcoal is  avoided in
the pure-air process (Reinluft) in that the material used
is not prepared activated charcoal, but cheap semicoke
or hard coal, peat, brown coal, and other similar carbon
carriers, calcinated at about 600° C.  Without additional
provisions and expenditures, they activate themselves
during their  application. The pure-air process is dis-
cussed in detail,  indicating useful information on econom-
ic replaceability, required floor space,  auxiliary mate-
rials,  utilizability  of amounts collected, adaptability,

The devices  (such as temperature controllers, control
valves, air blowers, etc.) required for control guidance,
and monitoring of plants for refuse incineration only
and plants for refuse incineration with heat utilization
are discussed and illustrated.  In design work, con-
sideration must be given to the fact that the plants are
usually operated by relatively unskilled personnel, also
that the very rough  operation of the plant with much fly
dust and acid effluents requires tough and corrosion-
resistant devices.  It is also important for the control
system to be protected against interruption in operation
by  blockage.  In the heat utilization design, the scheme
of the units conforms to a great extent to that of a steam
generating plant; auxiliary oil or gas firing may be used
to provide extra steam during peak load periods.

A recirculating filter system equipped with a sludge-free
fine-filter for collecting dust in a refuse incinerating
plant in Hamburg, Germany is described and illustrated.
Much dust invariably rises from refuse storage bins
located underneath the furnaces and must be controlled.
The  air filter system used involves spraying a wetting
material under pressure through the recirculation cells
from the wetting  material  container from underneath the
recirculating filter element that is normally used only
for the wetting agent for contact rinsing.  The wetting
material, as it passes through the recirculating filter
cells, loosens the accumulated dust deposited on the
cells, becomes enriched with it, and forms a  sludge
precipitate at its bottom.  This sludge, in turn, is dis-
charged at the bottom of the wetting material container
and passed to settling tanks "whence it is recirculated
into  the system after subsequent settling and filtration.

AND MICE TO CARBON MONOXIDE POISONING.  Trans-

£7(3): 343-345,  June 1964.  8 refs.

The aim of this work was to study the effect of adreno-
cortical insufficiency and hyperfunction on resistance to
carbon monoxide poisoning.  A total of 138 rats  and 45
mice of both sexes was used.  CO poisoning was pro-
duced through static asphyxiation with concentrations
of CO at 10 and 1. 6 mg/1 with  exposures of 15,  30, and
180 minutes.  Eight days before  the asphyxiation the
adrenals were  removed from 25  rats, autotransplants
of the adrenals were performed  on 63 rats by Kulagin
and Shurygin's method.  In one of the series  of experi-
ments  15 mice were given intramuscular injections of
0. 2 unit/kg of ACTH for a week  before asphyxiation.
The following indicators were  studied:  Length of life
and animal behavior during and after asphyxiation, res-
piratory rate per minute,  rectal temperature, body
weight, leucocyte and eosinophil count,  blood formula.
The adrenal  transplants were  examined histologically.
Following  adrenalectomy the animals were listless, in-
hibited,  and  slow to react to tactile and pain stimuli for
a period of 5 to 7 days.  Within a week after  the opera-
tion, 45  percent  of the animals showed a drop in body
weight of 10  to 20 grams and a 23 percent reduction in
oxygen consumption.  The adrenalectomized rats were
more subject to pustular diseases of the skin.   Within A
week after removal of the adrenals  the number  of eosin-
ophils had more  than doubled;  the leucocyte count in-
creased an average of 8000.  A week after adrenalec-
tomy the sensitivity of rats to CO increases.  Sensitivity
of rats to CO poisoning remains  high during the first 2
weeks after autotransplantation of the adrenals.  A
month after the operation this  sensitivity is close  to the
resistance of intact animals.  Preliminary injections of
ACTH increases  the  resistance of rats to CO.

In an effort to define the mechanism of the interaction
between dusts and infections in the parenchyma of the
lung, the authors studied the influence of the inhalation
of inert dusts,  which had been deprived of all true chem-
ical  toxicity, on experimental  infection with Mycobac-
terium Kansasii var. luciflavum in the guinea pig.  Bio-
logical, radiological, histo-pathological and bacterio-
logical examinations were carried out  systematically
and  showed the  aggravating influence of carbon  dust on
this  type of infection.  Inhalation  of dust is sufficient to
convert a local  inoculum which is usually incapable of
provoking lesions into a pathogenic one.  This aggrava-
ting  influence of dust shows itself by important  radio-
logical, anatomical and histo-pathological changes and
by a considerable increase in the  number  of germs iso-
lated from the parenchyma of the  lung.  It is a function
of the importance of the bacteriological inoculum and
the time of infection, before or after the influence of
the dust.  It does not appear after inoculation with non-
viable germs.   (Authors'  summary)

After defining the aggravating effect of the inhalation of
inert dusts on the development of experimental myco-
bacterial  infection, the role of anti-tuberculous chemo-
therapy in the guinea pig submitted to the  double effect
of dust and infection is studied.  It is shown that when
"in vitro" active antibacterial substances  are used on
the strain of mycobacterium, they are capable of atten-
uating and avoiding serious tuberculous lesions in the
lungs of untreated animals if given early and regularly.
Previous  dust inhalation in the guinea pig  allows germs
which  are only slightly pathogenic to form lesions and
this gives excellent "in vivo" conditions for the study
of the  activities of new anti-tuberculous substances on
so called "atypical" mycobacteria, which are sometimes
responsible for chronic infection.  (Authors' summary)

 Cochleo-vestibular  disorders are observed rather rarely
 in oxycarbonated intoxication, especially with respect to
 its great  frequency.  In effect,  carbon monoxide does
 not exercise an elective toxic action upon the ear .'Essen-
 tially it causeG general and nervous manifestations and
 it produces hearing disorders and objective vestibular
 disorders only occasionally.  Their rarity may perhaps
 be more apparent than real because these disorders are
 often discreet and are  really in the background in the
 general and rather severe picture of acute intoxications;
 they are often voluntarily overlooked in the case of
 chronic intoxication which is above all objective and even
 this chronic intoxication is often overlooked.   However,
 the literature on the subject does offer several observa-
 tions of indisputable cochleo-vestibular lesions; these
 observations have been published during or after cases
 of intoxication due to carbon monoxide.  Three cases of
 acute intoxication are reported.

substances, components of the respiratory enzymes,
on carbon monoxide poisoning and other forms of anoxia,
an interest was  taken in the biochemical alterations
accompanying hypoxia.   Some reports indicate that the
blood level of riboflavin (vitamin 63) is lowered in rab-
bits subjected to acute carbon monoxide poisoning.  The
aim of the present work was to perform more detailed
analyses.  The investigations were carried out on 23
white rats and 27 rabbits.  Riboflavin was supplied in a
concentration of 3 mg percent during three  days  before
the experiment.  The animals were poisoned in a special
chamber by a mixture of carbon monoxide with air.  The
contents of the vitamin B^ in the muscles and liver were
estimated fluorimetrically. Riboflavin in blood was also
determined.   As the result of experiments the following
average standard values of total riboflavin were  recorded:
in rabbits - blood 21 gamma percent, muscles 199 gam-
ma percent, liver 960 gamma percent; in rats -  muscles
393 gamma percent, and liver 1313 gamma percent-
Acute carbon monoxide poisoning in rabbits brings about
a statistically significant decrease in total riboflavin in
muscles (by 25 percent).  No  similar changes in the
liver of poisoned rabbits were observed.  On the contrary,
the acute poisoning evokes in  rats no significant  dif-
ferences in the riboflavin concentration of liver and
muscle  tissues. The changes of riboflavin  concentration
in the muscles and blood of rabbits are connected "with
the general stress effect of carbon monoxide poisoning.

ENCEPHALOGRAPHIC PATTERNS IN CASES OF CHRO-

Translated from polish. Folia Medica Cracoviensia,

Neurological tests and the  EEC method have shown that
exposure to low concentration of CO are not responsible
for extensive damage to the central nervous system.  It
is,  however,  possible that chronic exposure to CO has a
retarding influence on the bioelectric activity of the
brain tissue,  manifested in clinical pattern as the neu-
rasthenic syndrome.  EEC tracing with inhibitory effect
on bioelectric activity frequently found in cases of chronic
exposure to CO occurs  in some physiological phases of
healthy individuals,  particularly in various types  of neu-
roses and pseudo-neuroses,  and is not a unique charac-
teristic of carbon monoxide.  EEC examinations in cases
of chronic exposure to  CO may be  of value as a means to
control the existence of harmful  conditions in considering
large groups of exposed individuals.  In single instances,
EEC examination alone cannot be considered as decisive.

STUDIES ON AEROSOLS:  SYNERGISTIC RESPONSE OF
THE PULMONARY AIRWAY RESISTANCE ON INHALING
SODIUM CHLORIDE AEROSOLS AND SO£ IN MAN.
Translated from Japanese.  Sangyo Igaku, £(2): 18-24,
Feb. 1962.  26 refs.

While inhalation of sodium chloride aerosols showed no
irritating response in all the cases, SO2 gas induced
remarkable increases of airway resistance in  a study
calculating the pulmonary air flow resistances in 1 3
healthy male adults.  Alveolar pressure and the flow
rate in and out the airway were measured by the inter-
ruption technique, and pneumotachometry and  responses
were compared after 5-rnin inhalations of submicronic
NaCl aerosols,  SO2 in concentrations  of 1. 6-56. 0 ppm,
and an SO2-aerosol mixture.  Monodisperse saline  aero-
sols with CMD 0. 22 microns were generated from 2 per-
cent NaCl solution through a Dautrebande D30  device,
and SO2 inhaled -was ejected from the iron pressure tube
through e. capillary rotameter to obtain constant concen-
tration.  The  enhanced response to SO2  gas  was 2 to 50
percent above the pre-experimental control  value.  When
the SO2-aerosol mixture was inhaled,  the percentage
response change increased synergistically,  showing 20
to 80 percent  above the control value.  A hypothetical
explanation on the synergism may be made by  La Belle's
theory which involves pulmonary penetration of particles
and gas in terms of  size and Henry's constant.  (Author's

A SYMPTOM-COMPLEX DUE TO INHALATION OF
CASTOR BEAN DUST.  Translated from Japanese.  Jap.
J. Indust.  Health, 4(11):23-30, Nov. 1962.

Acute  conjunctival congestion, chill, fever,  leucocytosis
with neutrophilia, albuminuria and excessive urobilino-
gen in the urine have occurred as acute ricin intoxica-
tion by inhalation of castor bean dusts, and expiratory
dyspnea and cough have occurred  by allergen inhalation
after the sensitization in workers exposed for a long
period to the dusts.   Some workers  in an oil mill com-
plained of acute conjunctival congestion,  rhinorrhea and
chill,  as prodrome, from 30 rnin. to 3 hr after the  ex-
posure to castor bean dusts; then  they suffered from
arthralgia  and headaches  with fever, cough,  and sputum.
Those  who were exposed for short terms were attacked
strongly with  conjunctival  congestion,  rhinorrhea, chill
and fever,  while workers exposed for long terms were
attacked mainly with expiratory dyspnea and cough.
During exposure to the dust, leucocytosis with neutro-
philia, albuminuria,  and excessive urobilinogen excre-
tion in the  urine were detected in  many cases.  Anti-
bodies for  allergen and promoting action to the hemag-
glutination by ricin were also detected in the  serum of
the workers.  A month after the exposure, the tendency
to an increase of eosinophils was  observed.   The rectal
temperature rose an hour after the intramuscular injec-
tion of crude pomade extract or ricin in an experiment
using rats.  Twenty-four hours after the  injection, con-
gestion and hypertrophy of liver,  kidney, and spleen,
and lung congestion and hemorrhage, brain,  digestive
canal,  peritoneum,  genital glands, and adrenal glands
were observed by dissection.  Precipitation for the re-
spective fraction was positive in the serum of sensitized
rats with ricin or allergen fraction.  The  ricin sensitized
serum of the rats inhibited hemagglutination by ricin.

EFFECTS  OF SULFUR DIOXIDE ON HUMAN PULMON-

Indust.  Health, 3J2):77-85,  Feb.  1961.

The 46 healthy males, who were  subjected to the inhala-
tion of 1-45 ppm  SO2 gas for 10 min through a mask from
a high-efficiency gas changer, did not show any symp-
toms of poisoning except for a few persons after inhaling
1-5 ppm of the gas.   Changes of clinical symptoms, res-
piration rate, pulse rate, vital capacity,  0. 5-sec expira-
tory capacity,  and Wright's expiratory peak flow rate
were measured for all subjects.  When exposed to 10-30
ppm SO2 gas, all subjects experienced a sense of burning
of the upper  respiratory  tract,  coughing,  chest  tightness,
and in  several  persons moist rales in the chest  were
heard.   A  slight increase of pulse and respiration rate
was observed in about 10 percent of the subjects -with no
proportional relation to the concentration of SO2-   The
0/5-sec  expiratory capacity and Wright's peak flow rate
showed a linear decrease in proportion to the increase
of SO2 concentration, that is,  a decrease by 10  percent
in 10 ppm  and by 15 percent in 40 ppm.  It was notable
that the vital capacity remained constant.  The lowest
limit of SO2  concentration which induced the broncho-
constriction was  about 1. 6  ppm.  Within 10 min after the
inhalation  of the gas, the physiological changes  returned
to the pre-inhalation level.  When 15-41 ppm of SO2 were
inhaled several times for 10 min,  the bronchial response
tended to lessen and the  subjects  seemed to become ac-
customed to  the SO2-  When the subjects inhaled using
the bronchodilator (isoproterenol hydrochloride) aero-
sols, the constriction of  the bronchi resulting from SO^
was immediately released and no constriction by repeat-
ed SO2 inhalation occurred.  (Author's summary, modi-

RADIOISOTOPES IN THE STUDY OF PULMONARY
RESPIRATORY FUNCTION.  [Radioisotopi nello studio
della funzione respiratoria polmonare.J  Translated
from Italian.  Recent! Progress! in Medicina,  37(1):1-
46, July 1964.

A critical review of current methods perfected for the
study of the pulmonary respiratory function through radio-
isotopes is presented.  It was concluded that:  (1) these
methods facilitate the separate investigation of the 3
elementary processes of ventilation,  perfusion, and dif-
fusion;  (2) the radioisotope methods  are  divided into two
groups:  the first group employs  the in vitro count of
samples of expired air; this method offers great pre-
cision and is of tremendous interest in the field of experi-
mental  physiology;  a second group employs in  vivo counts
from outside the body;  this method offers a lesser degree
of precision but it is extremely practical; this  group is
definitely highly useful in the field of clinical practice.
(3) the radioisotope techniques,  compared to the

conventional methods,  offer substantial advantages:
they are less laborious; they are reproducible, given
the lesser degree of inconvenience for the patient,  even
after a  short time; they correspond completely under
experimental conditions to the normal physiological
mechanism;  and they are more sensitive to even mini-
mum functional variations.   (4) The study of the pul -
monary respiratory function with radioisotopes should
still be considered in the development phase; broader
and more reliable improvements are  certainly possible.

GLYCOGEN CONTENT OF LIVER OF RATS IN CASE
OF POISONING BY CARBON MONOXIDE.  [Zawartosc
glikogenu w watrobie przy zatruciu tlenkiem wegla.J
Translated from Polish.  Folia Medica  Cracoviensia,
7(3):437-442,  1965.  5 refs.

This study compares the degree of disturbances of car-
bohydrates under the effects of carbon monoxide after
administration of large doses of adrenalin.  The evalu-
ation was made on the basis of the behavior of liver
glycogen in rats, while considering the  condition and
content of liver glycogen is a sensitive index of the
activity of the cell on the one hand and of the processes
of glycogenolysis and neoglycogenesis on the other hand.
The  experiments were carried out on 36 hooded rats  of
both sexes, weighing 120 to 150  g.  When the animals
were killed and their diaphragm opened, small seg-
ments  of their liver were studied.   Lumps of liver were
fixed for 24 hours in Rossman gas at 0° C and immer-
sed in blocks  of paraffin.  This method  makes it possi-
ble to  observe accurately the size  and quantity of the
grains of glycogen and its location in the liver lobe.  The
results show that as a. result of the effects of  carbon
monoxide there is intensive glycogenolysis in the liver
tissue.  During the first  stage the  glycogenolysis affects
the periportal area and later the central part of the
liver lobe.  Hypoxia in combination with the blocking of
the activity of respiratory enzymes can cause a switch
of the pH center inside the  cells in the direction of fer-
mentation and hydrolytic decomposition of glycogen.
When conceived in this way, glycogenolysis would be an
expression of direct damaging of the metabolism of the
liver cell.

CYTOCHROME OXIDASE AND PEROXIDASE ACTIVI-

ACUTE POISONING BY CARBON MONOXIDE.  [Zacho-

Folia Medica Cracoviensia,  7_(3):429-442,  1965.  12 refs.

The purpose of this study was an investigation by means
of histochemical methods of the  influence of CO on the
activity of cellular oxide  reducing enzymes in experi-
mental acute poisoning by carbon monoxide.  Liver was
selected because liver tissue  is one of the animal tis-
sues which is very rich in enzymes,  and its paren-
chyma is considered to be homogenous both biochemically
as well as histologically.  Fresh fragments of the liver
tissue were frozen and strips of 75 microns were used
for a Nadi's  indophenolic reaction, and 40-micron strips
were used for a benzidine reaction.   It was established
that indophenolic reaction was strongly blocked in strips
of liver of rats which have been subject to the effects of
carbon monoxide.  In six poisoned rats there was no
reaction at all, which would indicate that the enzyme was
completely blocked.  In 12 animals the activity of the
enzyme was  evaluated as poor,  and in two it was evalu-
ated as medium or strong. Benzidine reaction in liver
lobes of a rat shows a rather  even distribution both in
the center as well as on  the periphery.  In the liver of
rats poisoned by CO the  intensity  of the  reaction is clear-
ly poorer.  Only in one case there was no benzidine re-
action,  which may indicate that peroxidase was complete-
ly inactivated.  From the results  of the  studies which are
included it is concluded that the activity of both enzymes
under study in acute poisoning by  CO is  heavily blocked.
The period during which the animals were kept in an
atmosphere of carbon monoxide was very short and lasted
from two to three minutes. The short duration of the
activity of CO in combination  with the results obtained
from histochemical studies shows that in the course of
poisoning by carbon monoxide rapid changes occur in
the oxide reduction system of a liver cell.  The results
compiled show that cytochrome oxidase is subject to a
stronger blocking than peroxidase.  A considerable de-
crease of the activity of  cytochrome oxidase is extreme-
ly important for an explanation  of the  pathogenesis of
poisoning by carbon monoxide,  because  the enzyme is
responsible for the terminal linkage of tissue combustion,
i. c. for the transmission of electrons from the substra-
tum to oxygen.  The discontinuation of the linkage  of the
tissue combustion must intensify the condition of inade-
quate tissue  oxidation caused  by the anoxemic effects of
CO.

The behavior of glutathione and glucose-6-phosphate
dehydrogenase of red blood cells was studied to ascertain
the possible toxicity of carbon monoxide  for these sys-
tems.  Nineteen men, employed in a plant producing
illuminating gas,  who had undergone supraliminal inhala-
tions of carbon monoxide were examined.  In six subjects
with carboxyhemoglobin above normal, a decrease in the
glutathione ratio was found, while the glucose-6-phos-
phate dehydrogenase decreased. However,  comparison
of the average values obtained with those of a group of
normal subjects did not show any statistically significant
differences.

The effect of chronic exposure to CO at varying concen-
trations on carbohydrate metabolism was studied in
guinea pigs and rabbits.  Fasting blood sugars were de-
termined monthly.  The assimilation of carbohydrates
was tested by the "loading method" using 1. 7 gm gluco'se,
 1. 5 units insulin, and 0. 37 ml (1:1000) adrenalin per kg
body weight.  Throughout the experiment the animals
were fed normally.   Prolonged exposure to CO led to
 disturbances in carbohydrate metabolism as  shown by
 an increased rise of glycemic curves,  and occasional
 distortion. The chronic effect of CO concentrations of
 0. 012-0. 018 mg/1 on guinea pigs indicates a need to
 reduce the maximum permissible  concentration of this
 gas in the air.

CHRONIC BRONCHITIS AND PULMONARY EMPHYSEMA.
Translated from Russian,   Arkh.  Pat. ,  Vol.  26,  p.  3-
18, 1964.  102 refs.

Chronic bronchitis was defined by the 1962 European
Symposium of WHO in Moscow as the chronic and re-
current generalized irritation or inflamation of the
smaller bronchi, characterized by the increased forma-
tion of  sputum  continuing for at least three months with-
in a two year period.  The disease, as understood by
this definition,  is examined in detail and its relationship
with pulmonary emphysema is  analyzed.  The work of
other researchers  in this field is reviewed. The  major
topics discussed include the following:  the etiology of
chronic bronchitis, touching upon bacterial and viral
agents  and smoking; the  hypersecretion  of mucus  and
its effect on the structure of the bronchi; post mortem
lung studies; the effects  of chronic bronchitis on pul-
monary arteries;  criteria  for defining emphysema;
etiology of emphysema and  studies of lung pathology
with an improved lung fixation  technique; the effects of
emphysema on the  structure of bronchioles and alveoli;
the characterization of centrilobalar and panacinar
emphysema; emphysema and hypertension in pulmonary
vessels and hypertrophy of  the heart; frequency of em-
physema in old age; and  lobar emphysema of newborn
and small children.  It is concluded that chronic bron-
chitis must be distinguished from secondary focal lesions
of the bronchial tree, which occur  as a result of suppura-
tion or  diffusion of a process from the focal bronchi-
ectases.  Chronic bronchitis and especially bronchiolitis,
as well as the disturbance of the  secretory and motor
function of the bronchi and bronchioles brings with it a
disturbance of pulmonary ventilation and the develop-
ment of emphysema which might be panalobular or
centrilobular, depending upon the caliber of the injured
bronchi.

STATISTICAL INVESTIGATION OF BRONCHIAL CAR-
CINOMA IN NORTH-RHINE-WESTPHALIA.  [Statistis-

23 refs.

Investigations "were  carried  out using 1229 questionnaires,
more than 20, 000 autopsies  (including 1807 cases of
bronchial carcinoma), and the material of the general
population statistics of Nordrhein-Westfalen as well as
of Denmark, Norway, Belgium,  Holland,  Austria,  and
Switzerland.  Since the beginning of this  century, bron-
chial carcinoma found during autopsies in the pathological
Institutes at Dusseldorf, Bonn, and Solingen has in-
creased in relation to the general population statistics.
The increase of bronchial  carcinoma  found in autopsies
is noticeable in all age  groups and is  highest for men
immediately before age  60.  The percentage of bronchial
carcinoma found during  autopsy corresponds to the con-
cept of "relative mortality from bronchial carcinoma "
in general population statistics.  The range of the age
maximum of absolute mortality from bronchial carcin-
oma,  however, has not remained constant over the years;
it moves like a "-wave" through the age groups where
heavy smoking of cigarettes  first assumed the epidemic
proportions of a mass addiction.  However, it will  be
found from the data of the  general population statistics of
Switzerland that the  displacement of the maximum of
absolute mortality from lung cancer to increasingly
higher age groups had already begun prior to the First
World War.  The explanation of this "wave" is not diffi-
cult if in addition to  the  absolute mortality from bron-
chial carcinoma, the relative mortality from bronchial
carcinoma and the total  mortality are taken into account.
The correlation between these three parameters  is ex-
plained by a simple numerical example.  Statistical
correlation analyses  of various parameters are included.

of 1 month were interposed at 500 and 1500 hr.  There
was no residual carbon monoxide in the blood of animals
who had been chronically poisoned.   The  kinetics of the
fixation and elimination of carbon monoxide follows a
simple physiological phenomenon.  The results agree
with work by others that carbon monoxide is absorbed
and eliminated without change and without any storage
except in  the blood.  The value of carboxyhemoglobin
in the plasma is very low.  Animals  exposed for 500 hr
to 250 ppm of CO  after a previous exposure of 2500 hr
to 100 ppm showed the same poisoning as  animals who
had not received the first exposure.  It is concluded
that there was  no  cumulative effect or persistence in
the blood  of carbon monoxide after long exposure to low

Med. Prevent.  (Genoa),  7_(3):205-220, Sept.  1966.

Research carried out in Genoa deals with the effects of
air pollution on the  respiratory system and on some
indices of respiratory function.  The studies  were made
on elementary school children living in two zones with
different levels  of such pollutants as sulfur dioxide,
suspended particles, and deposited matter.   The statis-
tics show that the children living  in the more polluted
zone had longer and more frequent episodes of bron-
chitis as well as rhinitis,  cough,  and phlegm.  A
decrease in the  peak respiratory  flow (Wright) "was
observed.  The  seasonal course of these syndromes "was
followed.  The results show that these indices persist
during the hotter months if there  is no decrease in air
pollution, whereas other respiratory ailments that had
no correlation to air pollution showed similar seasonal
curves in the two zones,  even though the absolute values
of these indices were different.

Evidence that sulfur dioxide and nitrous gases which
are effective in low concentrations also produce changes
in the individual indicators of group diagnostics is
demonstrated.  Differentiation was made between effects
on control  groups and the group from the polluted atmos-
phere as well as  between the influence  of both the com-
bined effect of sulfur dioxide and nitrogen peroxide and
the effect of sulfur dioxide alone.   The method of the
erythrogram is also described.  This method is based
on the increase of the number of erythrocytes in child-
ren living in air-polluted areas.  The methemoglobin
level in the  blood of children is significantly increased
by the air pollution caused by nitrogen peroxide in the
surroundings of large chemical works.   Thus, another
possible cause of the development of latent methe-
moglobinemia in school children  between the ages of 8
to 10 is explained.   (Authors' summary, modified)

STUDY OF AIR QUALITY IN BUILDINGS,  I.  RELATION
BETWEEN DEGREE OF WEARINESS, CONCENTRATION
OF CO2, AND POLLUTED ENVIRONMENT.  Text in
Japanese.  J. Japan Air Cleaning Assoc. (Tokyo), 3J3):
11-15, 1965.

The relationship between indoor CO2 concentration and
weariness was investigated.  An examination was made
of 30 people for three days.  Ten were working in a part
of the room "where the CQ^ concentration was low (0. 14-
0. 17%) and 20 in a high-CO2 section of the same room.
The degree  of "weariness was defined by the "flicker
value".  Graphed results indicate that "weariness is
greater for  people working under a higher CO2 concen-
tration than those working under a lower concentration.
Also investigated "was the relation between the CO2
concentration and amount of ventilation required per
person.  The average value of  CO2 emitted by a person
with an R.M.R.  (Metabolic  Ratio) value  of 0. 4 to 0. 6 is
about 18 liters/hr.   The threshold limit value of CO2 is
1. 5 percent in Japan and 0. 5 percent in the U. S.  The
most desirable value is less than 0. 1 percent, which can
be obtained  by the ventilation of 10 cubic meters/hr per
person.  CO2 values were measured in offices in winter
when steam radiators are in operation.  A graph in-
dicates a maximum value of 0. 32 percent.   Other mea-
surements made in 116 offices without air  conditioners
gave average values between 0.16 and  0.2 percent.
Values appeared to be lower in summer  than  in winter.
CO2 concentrations in an apartment using a gas heating
apparatus "was measured at  0. 66 percent.

Changes  in behavior and in the EEG were observed in
male rabbits exposed to carbon monoxide.   Fast waves
disappeared gradually and slow "waves with spindle
bursts appeared in the neocortex after the  inhalation of
pure CO gas.  Later slow waves  of distinct high voltages
were demonstrated in the neocortex, especially in the
limbic and optic areas, about 40 min.  after contact with
CO gas;  at this time the serum CO-Hb concentration had
reached  35 percent.  Furthermore,  low voltage slow
waves  with spindle bursts were demonstrated after 80
min. ,  when the CO-Hb concentration was 55 percent.
At this time the rabbits were still sensitive to sound and
to other  stimuli.  However, they could not walk.  Slow
waves  appeared diffusely in the anterior and posterior
hypothalamus, central nuclei of thalamus, midbrain
reticular formation, amygdala, hippocampus, pallidum,
caudate nucleus,  corticospinal tract and internal  capsule.

  Increases of the threshold of the arousal reactions in the
  neocortex were examined after successive stimulations
  of the midbrain reticular formation,  the central nuclei
  of the thalamus and the posterior hypothalamus.  Almost
  no changes were shown in the midbrain reticular forma-
  tion, and slight increases of threshold were demonstrated
  in the central nuclei of the thalamus  and in posterior
  hypothalamus, about 40 min. after onset.   The increases
  of threshold,  however, were distinctly shown after 80
  min. to be strongest in the  posterior hypothalamus and
  the central nuclei of the thalamus and weakest in the
  midbrain reticular formation.   Other findings  are
  reported and it is concluded that CO  caused disturbances
  in the limbic system,  in the hypothalamic activating
  system,  on motor function and on the visual pathway.
  Only slight disturbances were  observed in areas related

  THE TOXICOLOGICAL AND HYGIENIC SIGNIFICANCE
  OF OZONE.   [Die toxikologische und hygienische
  Bedeutung des Ozons.]  Translated from German.  Arch.
  Hyg. Bakteriol.  (Munich), 1_5CH1-2):62-78,  1966.   62
  refs.

  The toxicological and bactericidal properties of ozone
  are  reviewed.  The acute toxicity of ozone to laboratory
  animals is reported as being diverse and variable from
  species to species.  Chronical exposure results in
  damage to the respiratory organs,  i.e.  in bronchitis
  and  lung emphysema,  limitation in weight increase of
  young animals, and reduced urine acidity.  When man is
  exposed to 4 to 5 ppm, a lung edema develops within a
  few  hours.  Lower concentrations primarily affect
  respiration by irritation and cause headaches  and nausea.
  In animals, the exposure to low ozone concentrations
  produces immunity to subsequently applied lethal doses.
  Tolerance to ozone has also been brought about by
  germanium oxide.  Conversely, ozone  has been shown
  to produce tolerance for ketene, H2O2  and NO£.  The
  mode by -which ozone becomes  biologically effective is
  not yet fully elucidated.  Presumably,  free radicals
  causing oxidation processes are formed similar to those
  produced by nuclear radiation.  These processes, in
  turn, set free adrenalin, noradrenalin and bradykinin.
  The strongest bactericidal effects of ozone are  obtained
  at high relative humidity and low temperature.  In prac-
  tice the germicldal effect of ozone can  only be applied
  to sterilizing water.  The deodorizing effect is  generally
  accepted but requires  concentrations exceeding the maxi-
  mum allowable concentrations.
 The effects of magnesium on the human were investigated
 by medical observations over a period of 12 years, air
 samples taken in a magnesium refinery, a study of the
 levels of magnesium in the body fluids as well as X-ray
 examinations.  At the plant in question, magnesium is
 produced by calcination and reduction of dolomite
 (CaCO3-MgCOs) in an electric furnace under vacuum.
 Among 76 men  in the  magnesium plant, 28  (36.8 percent)
 complained of digestive disturbances of whom 18 (23.7
 percent) had stomach ulcers.  The incidence of stomach
 ulcers among other metallurgical  workers as reported
 in the literature as well as in the plant is 3.5 percent.
 The highest concentration of MgO  occurred during the
 operation and discharge of the reduction furnace and
 during the extraction  of the condensation crucibles. The
 exposed men had an increase  in urinary magnesium con-
 tent of 115 percent, and an increase of serum MgO con-
 tent of 123.6 to 140.5 percent as compared to those not
 exposed.  The magnesium content of the blood and urine
 were the same before and after the working  shift.  Air
 samples showed concentrations from 0.050 to 0.116 mg
 of MgO per liter of air.  A definite relation  exists bet-
 ween an exposure to magnesium aerosols and fumes and
 the incidence  of gastric and duodenal ulcers.

The various aspects of inhalation and deposition of
therapeutic aerosols along  the respiratory tract are
reviewed.  For good deposition of the particles along the
primary respiratory tract, i.e.,  trachea, bronchi, the
particles should be 5-10 microns in diameter.   However,
to ensure a higher percentage of penetration and reten-
tion in the bronchioles and  alveoli,  the particles should
preferably be less than a micron  in diameter.  For
optimum therapeutic results, the aerosol should be
monodispersed.  Various devices for aerosol production
are available.   The production  of a liquid aerosol can be
accomplished by the following:  atomization with a gaseous
flow,  by hydrodynamic atomization and  by centrifugal
atomization.  Production of solid aerosols can be
accomplished by pulverization and dispersion by air
current, or by a controlled pulverization.

pupils  in Amagasaki were examined from 1960-1962 by
the Wright peak flow meter.  As to the evaluation of air
pollution, suspended particles were estimated by the
tape air sampler method,  and sulfur dioxide by the
"lead peroxide" method.   The investigation period in
Tokyo was from November 1961 to March 1962.   Wright
peak flow value, breathing capacity by bitarometer, and
0. 5 second amounts were measured in triplicate per
person and the maximum value was taken.  Peak flow
value was measured once per month for a total of 5
times, and breathing capacity and  0. 5 second amounts
were measured once in March.  The investigation in
Amagasaki was from September 1960 to May 1961 and
4 measurements were conducted during the period in
two month intervals.   The degree of air pollution was
expressed by the suspended particulate concentration
index determined with a tape  air sampler.  The appara-
tus was placed near the school for measurement.
Monthly checks on fallen dust  concentration and SO were
made in Amagasaki.  The results showed a relationship
between the index of suspended particles and peak flow
rate.  The higher the concentration of suspended  parti-
cles the lower  the peak flow rate.  Variation in peak flow
rate was large in areas of intermediate pollution  and
change in the degree of pollution agrees with that of
peak flow rate.  This  is indicative of the relation be-
tween the prevention mechanism of the body and air
pollution.  Also these can be  classified into a  group of
(1) high peak flow rate when the degree of pollution by
index of  suspended particles  is small,  (Z) an intermedi-
ate peak flow rate when the degree of pollution is inter-
mediate.  These results indicate that a long term
observation and group diagnosis instead  of individual
diagnosis is  necessary when  the influence of air pollu-
tion is judged by peak flow rate.  Even when difference
in SO concentration of 1. 0 mg 803/day/100 cm2 PBOz
was observed, there was no difference in peak flow rate
between the two districts.

 As an example of the relationship between the number
 of cases of pneumoconiosis and the level of contamina-
 tion of the air with dust,  a study was conducted on the
 health of sand blasters in the USSR during the years
 1947-1950.  Working conditions at different plants varied
 sharply, depending on the volume of work,  the dimensions
 of the casting, the arrangement and state of the sand-
 blasting chambers,  and on the measures taken for indiv-
 idual protection.  Only the composition of the dust
 inhaled by the workers, which contained 85-90 percent
 quartz particles remained the same.  Parallel investi-
 gations affirmed the belief 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 demonstrated 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.  Consequently,
it was affirmed that the especially active and dangerous
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 experi-
ments 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 sili-
coses caused by the action of dust of higher fractions.
Consequently it can  be stated that in the multifraction
dust the mass of fine particles was insignificant, since
this dust fraction did not affect  the character of the de-
velopment of silicosis.  Thus it is evident that the origi-
nation of silicosis is caused by  the mass  of the acting
dust as "well as by its fineness.  At the present time,
microscopic methods are still being used for the evalua-
tion 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.

Special project research by grant-in-aid for scientific

The chronic effects  of polluted air on elderly residents
of industrial and non-industrial areas  of Japan were
studied.   The  cities  involved were Tokyo, Osaka,
Northern  Kyushu,  Hiroshima, and Nara.   Lung autopsy
specimens were examined for coal dust accumulation,
degree of fibrosis,  and presence of emphysema  from
persons who had lived in the above-mentioned cities for
forty years  or more.  Living, long-time  residents of the
areas were given x-ray, pulmonary function, and other
examinations and were classified according to smoking
habits, age, sex, and presence  of cough and bronchitis.
The data from these studies are tabulated and represent
the work of 15  separate investigators.  The amount of
dust and soot in the  air of  these cities was also studied
as well as some meteorological conditions.  Results of
the dust measurements indicated that Hiroshima and Nara
had less pollution than the other cities.  This coincided
with the clinical findings which  showed that the residents
of the two lesser polluted areas had less  accumulation
of dust in the lungs, better ventilatory capacity, and a
lower frequency of abnormal linear shadows on lung
x-rays.

 using a bell jar, two animals from each group were
 decapitated and examined.   The relationship between the
 dry and wet weight of the lungs of each animal was
 analyzed. It is concluded that the negatively ionized  air
 significantly reduced the edematous  infiltration into the
 lungs caused by inhaling ozone.   The negative ions were
 shown to stimulate the endocrine system and improve the
 general metabolism  of the  organism, probably as a
 result of enhanced utilization of oxygen at the cellular

 differences were found,  except in one child.  When the
 mean flow rates, as percentages of normal values, were
 grouped chronologically and compared with the solution
 curves, one  dip was found on a day -with SO;? and smoke
 levels of approximately 800 and 300 ng/m .  This day
 •was also characterized by a temperature drop.  The
 study illustrates  how much one depends on meteorological
 variables to get experimental results.  The question also
 rose during the study "whether  asthmatic children are the
 most  sensitive group to register  effects.  It may well be
 that the children were fixed at such low flow rates, that
 they were not very sensitive to air pollution anymore.

between the COHb values calculated according  to the
methods of Forbes et al. ,  and of Hatch.  No dependency
of the COHb level on respired volume of air could be
detected.   The direct relationship between CO  content
of exhaled air and blood COHb level is statistically
significant. The range of  values for a single subject
•was considerably narrower than for a group.  The  rough
determination of blood  COHb level, using CO level in

globin  (COHb) by two independent spectrophotometric
procedures.  The concentration of COHb in venous blood
was found to be 0. 30 + 0. 14 percent in normal individuals.
In the presence of hemolysis, COHb values were found to
be elevated (0.55 - 5.1 percent) in every instance. Thus,
COHb appears  to represent a measure of total erythro-
cyte destruction.  Its determination can be  of value for
the assessment of hemolysis.

A total of 128 children (aged 8-10) from 3 Czechoslovak
towns were  examined (Bohdanec, Ohrazenice and Rosice).
SO levels of 0. 03-0. 32 mg/m  and nitrogen oxides  of
0. 005-0. 07  mg/m  were found in 2 towns; the other town
v/ith clean air "was used as a control environment.  The
pollutants cause an increase in erythrocyte  count as well
as a change in their size.  Lymphocyte count increased
and monocyte proliferation decreased significantly in
children from the polluted areas.  The  deviation of these
indices from normal was more pronounced in children
exposed to both  SOT and  nitrogen oxides than in  children
exposed to SO2  alone.

 globin level differed significantly in children from pol-
 luted areas,  compared to children  in a. clean environ-

 in the number of immature erythrocytes.  The effects
 of SO2 and nitrogen oxides are additive.  Methemoglobin

 lowering of the blood color index.   Globulin level was
 higher and albumin level lower in the blood serum of
 children from  areas with air pollution.  Due to the lack
 of ultraviolet radiation in the areas with air pollution,
 serum alkaline phosphatase levels were raised.  Child-
 ren from areas with smoke pollution also  exhibited
 moderate  growth retardation.  These changes demon-

The carbon monoxide content of the atmosphere was
measured at nine high-traffic-density street intersections
in the City of Zurich during 1961 and 1962 during rush
hours.  The 125 measurements indicated that the mean
carbon monoxide concentration is 30-40 ppm.  This
carbon monoxide concentration is well below the MAK-
value of 100 ppm.   Occasionally, mean values of 80-90
ppm were measured at the  intersection of Raemi Street
and Zeltweg, with temporary peaks of 95-120 ppm.
These high values were clearly attributable to slow
traffic,  traffic blockages, and, especially to stationary
vehicles with running engines that emitted considerable
quantities of exhaust gas.   The results  of carboxyhemo-
globin content determinations in the blood of 71 traffic
police officers showed  clearly that they must be sepa-
rated into  groups of  smokers and nonsmokers.

respectively.  The smokers exhibit high carboxyhemo-
globin contents, especially at the beginning of the duty
term.  In such persons, we found consistently values
as high as over  5%, whereas the mean values for the
nonsmokers were  around 3 percent.  The higher initial
values for the smokers caused a decrease during duty
in an atmosphere with high carbon monoxide concentra-
tion.  At the same  time, the lower initial values for the
nonsmokers usually increased.   Since the average carbo-
xyhemoglobin saturation values did not exceed the toxic
limit of 10 percent, it is not possible to conclude that
poisoning may occur in the course of traffic regulation
duties.  It was not possible to relate any serious  disease
symptoms or health-harming consequences with the
inhalation of carbon monoxide-containing air during the
term of duty,  as established by brief questioning of the
test subjects.   The fact, however, that 39 out of the 71
traffic police  officers,  i.e. , more than one-half,
experienced for a  period of 1-2 hours such symptoms
as headaches, nausea,  and loss of appetite, should not

Hematological  investigations of the peripheral blood
and the bone marrow -were performed on rabbits  with
acute manganese chloride poisoning.  The serum iron
level was also  determined.   The results  show that man-
ganese  chloride, when injected in toxic doses,  exercises
a manifold influence upon the blood formation system.
During  the early stage, as » result of a stimulation of
the bone marrow,  an increase in erythrocyte count and
in the hemoglobin content occurred in the peripheral
blood.  At the same time an iron deficiency was noted
in the body.  The inhibition of  hemopoiesis during the
later stage of the toxic effect of manganese upon the
blood forming system can be blamed upon the iron de-
ficiency; an accumulation of this metal in the bone marrow
is probably also involved.  In particularly sensitive
cases, there was both an inhibition of hemopoiesis and
an anemia from the very beginning of the poisoning.

A review of two cases of acute manganic pneumonia is
presented and the characteristics  of the disease are
briefly discussed.  From the anatomopathological point
of view, the observations which can be made are those
of an ordinary pneumonia alveolitis (alveoli filled with  a
fibrinoleukocytic exudate).  On the other hand, no con-
clusion can be drawn from quantitative analysis of man-
ganese at the level  of the pulmonary parenchyma: the
same figures have been found in the lungs of miners who
died from pneumonia and in those  of subjects who died
accidentally.  The reality of manganic pneumonia rests
on statistical studies made in many countries,  which
provide evidence of the abnormally high percentage  of
pulmonary illnesses in the various sectors of the man-
ganese industry.

several other illnesses.   Symptoms of chronic lead
poisoning were found in the course of the study, which
lead to an analysis  of the lead content of the blood and
urine of the subjects.  Measurements were also made of
lead in the air, soil, water,  and food products of the

 Lead levels are tabulated for 789 urine and blood sam-
 ples obtained from persons in 16 countries and major
 cities who had not been occupationally or otherwise ex-
 posed to lead.  Lead levels in blood and urine ranged
 from 7-26 |J.g percent in blood and 22-46 uG/1 in urine.
 Analysis of the data showed that the lead concentration
 in the blood is directly proportional to that in urine. An
 increase in the blood level of 1 |ig percent is accompanied
 by an increase  in the urine level of 1. 4 )ig/l.  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 |ig/l.  Since this is impos-
 sible it appears that the correlation line must be curved
 in the lower concentration range.  The  proportionality
 between the lead concentration in the urine and in the
 blood is considered as indirect evidence that lead at
 normal blood levels is excreted by glomerular filtration
 only.

 Experiments were conducted in laboratory animals with
 damaged lungs from industrial dusts.  The problem of
 etiology of pneumonia, interstitial changes at the lung,
 pneumoconiosis and, especially silicosis and silico-
 tuberculosis as a consequence of inhaling various
 industrial dusts was investigated.  It was concluded that
 different occupational dusts have entirely different
 actions on lungs.   Above all, Silica dusts enhance
 tuberculosis of the lungs and produce silicosis or sili-
 cotuberculosis with or -without the participation of
 tubercle bacilli.   The extent of the lung damage is
 governed by the SiOz content of the  dust.  The action of
 SiO£ is greatly modified by the admixture of other dusts
 (e.g. clay,  Bolus alba, calcium, corundum,  carborun-
 dum, etc.).  Under certain circumstances these admix-
 tures prevent silicosis.  Dusts low  in SiO2 or containing
 none at all produce harmless dusts  in lungs leading to
 uncomplicated pneumoconioses sensu Koelsch, recogni-
 zable by the  formation of dust pockets  in the lung tissues.
 Inhalation of manganese-containing dusts  (Thomas slag,
 Siemens-Martin  slag, MnO2) produces pneumonia.
 Aluminum dust produced peculiar changes in the lungs,
 leading to the formation of connective tissue in the
 structure of  the lung, i.e.  "structure sclerosis".   These
 pneumonia-like changes are favored by certain factors
 which appear as a  complex of factors.  The complex
 plays a role  in lung tuberculosis, together with social
 factors and the natural disposition of the patient.   Silli-
 manite,  dusted for more than 1-1/2 years, lead to lung
 changes which resembled lung cirrhosis.  Symptoms
 are accelerated in the presence of a chronic infection.

 In the manganese milling plant of a large West German
 industrial plant, five cases of manganism occurred
 among a workforce of only 18 men during a period of
 approximately four years.   This observation is signifi-
 cant because of the fact that, in this manganese milling
 plant, only ferromanganese, a metallic manganese, is
 ground.   With  regard to metallic manganese, the
 assumption to  date had been that it cannot cause chronic
 manganese poisoning.  It was established by animal
 experimentation that the  degree of harmfulness of the
 various manganiferous substances bears no relation to
 the degree of oxidation of manganese, but rather that
 the toxicity of  the manganiferous substances rises at a
 rate commensurate with  the percentage increase of the
 manganese concentration.  Chemical analysis showed
 that ferromanganese may be resorbed by any one of three
 methods of application.   Consequently, the absorption of
 manganese is possible not  only by inhalation, but also
 through the skin and by way of the gastro-intestinaltract.
 A temporary manganese  deposit is possible in practically
 any organ.  A  permanent deposit of manganese was ob-
 served primarily in the bones.  In a West German in-
 dustrial plant -which processes pure alloys for use in the
 production of high-grade steel, a considerable increase
 of cases of pneumonia among the -workers was observed
 during several years.  However, it was established on
 the basis  of intensive studies that the increased incidence
 of pneumonia was not caused by specific substances,
 particularly  by working -with manganese, but these cases
 of pneumonia rather were results of other factors, such
 as draughts, long-term unemployment, undernourish-
 ment,  weather conditions,  etc.  Animal experiments
 established the fact that inhalation of ferromanganese
 dust,  even if present at high concentrations, is not only
 unable to  produce pneumonia, but also is not a potential
 agent in creating "increased  susceptibility" to infection.

One group was exposed to NO2 without particles, another
group to NO2 plus carbon particles (most particles over
0. 25 n).  The third group was also exposed to NO2 plus
carbon particles (most less  than 0.25 fi).  Gas absorp-
tion was then studied using a method previously de-
scribed.  Rabbits exposed to NO2 and carbon particles
absorbed more NO2 in the upper respiratory tract than
the NO2-exposure group.  Differences in the absorption
pattern and the respiratory pattern when comparing the
two carbon particle  groups could also be observed. The
changed NO2 absorption pattern in the presence of car-

The pathology of workers engaged in the handling of
manganese is characterized by three nosological en-
tities: manganic pneumonia, chronic manganese in-
toxication and manganoconiosis.  In the present  state-
of-the-art  of ore extraction, the use of pneumatic drill-
ing leads to a considerable increase in the amount of
dust present in the air of working areas, concentrations
that are not influenced by the natural infiltration of
water into  the ore deposits.  The consequence of this
fact in the mines investigated here as well as in mines
of other countries has been an increased risk of in-
toxication.  Two medical surveys were carried  out, the
survey of 1949-50 and of 1957-58. These surveys show-
ed that manganese mines represent the principal source
of chronic manganese intoxication.  The medical survey
of 1949-50 revealed the  existence of two categories  of
neurological disorders.  In the survey of 1957-58, the
existence of three categories of clinical disorders were
revealed.  These disorders are all discussed in great
detail as are laboratory examinations and results.

the blood picture and some of its indicators (erythrocyte
count,  color  index, hematocrit value,  and volume of
erythrocyte).  Application of the-analysis of variations
showed that significant differences do exist, and that
these differences correspond  to the observed degree of
air pollution.  In addition it was  shown that the  organism
defends itself by a certain reaction against the influence
of the polluted environment, attempting in this way  to
offset its effects.  At the same time it was  proved that
the groups of children investigated differed essentially
from each other, so that it is  evident that the results
found are not accidental differences in the same basic

 THE DEGREE OF CARBONIZATION AS A CAUSE FOR
 THE DIFFERENT BIOLOGICAL AGGRESSIVITY OF
 COAL DUST.  [Stupen prouhelneni jako pricina ruzne

 The incidence of pneumoconiosis of miners in  20 Czecho-
 slovak coal mines was studied  by X-ray tests and cor-
 related  with the carbon content (geological age) of the
 coal.  A very good correlation was found which indicates
 that the hazard of a coal mine increases "with the carbon
 content.  It is highest for anthracite and lowest for
 bituminous coal.   These results agree with those from
 studies  in Great Britain.  The  effects  of exposure time
 and dust particle  size were taken into  consideration and
 are discussed.

 THE ETIOLOGY OF BRONCHIAL CARCINOMA.  EVAL-

 A questionnaire designed to shed light on environmental
 factors  of possible etiological significance was distrib-
 uted to  1000 lung cancer patients (mostly males)  or their
 families.  Males were more frequently affected than f e -
 males (940:60).  Of the respondents,  91. 4 percent were
 smokers.  The  greatest incidence of lung cancer was
 found  among hotel and  restaurant  (and tavern) employees,
 traffic and transportation workers, and metal industry
 workers.  A statistically significant low incidence of
 lung cancer (less than  one case per 1000 workers em-
 ployed in the area surveyed) was noted in occupational
 areas of agriculture, forestry, textiles, and health
 sciences.  A tabulation of patients according to size of
 locality  (including the cities of Wurzburg,  Schweinfurt,
 and As chaffenburg) is interpreted  as showing a greater
 incidence of lung cancer in urban areas, due to air pol-
 lution caused by traffic concentration and the presence
 of  industry. Exhaust gases, tars  and  chemicals are
 among the pollutants implicated.   The role of tobacco
 is  discussed.

 FIBRINOLYSIS IN ACUTE CO POISONING:  EXPERI-

Fibrinolysis and COHb levels were observed in 21 rab-
bits before and after exposure to 5 to 8 percent CO.   The
technique for determination of fibrinolysis is described.
Fatal intoxication with CO causes a significant rise in
fibrinolytic activity, and specifically a marked rise in
plasmin level.  Observation of plasminogen  behavior  in
vitro,  before and after plasminogen triggering, showed
a clear drop in 12 cases.  Thus,  in the other 9 rabbits,
plasminogen triggering which occurred after intoxication
and caused the increase in free plasmin was counter-
acted by the appearance of an excess of new plasminogen.
The increase in fibrinolysis rate could not be  correlated
with COHb level.  In conclusion,  the fluid blood noted
post-mortem in cases of CO  poisoning is probably due to
the increased fibrinolysis rate, but the lack of correla-
tion between the  increase in fibrinolysis rate and the
COHb level suggests that blood fluidity is caused by non-
specific stress-triggered mechanisms.

TWELVE YEARS OF EXPERIENCE IN THE FIELD OF
CHRONIC CARBON MONOXIDE POISONING IN SWEDEN.
[12 Jahre Erfahrungen auf dem Gebiete der chronischen
Kohlenoxydvergiftung in Schweden. ]  Translated from
German.  Arch.  Gewerbepathol.  Gewerbehyg. (Heidel-
berg), Vol. 13, p. 97-131,  1954.   80 refs.

The incidence  of CO poisoning has  risen since the appear-
ance of generator gas from automotive exhausts in Swe-
den in about 1939.  In December 1940,  the Fuel Commis-
sion issued directions for the manufacture and use of
generator gas motors, followed by further efforts to
alert the public to the danger of CO poisoning from the
use  of generator  gas motors.  The exhaust of a generator
gas motor contains a greater quantity of CO (5 t o 8 per-
cent) than does that of a gasoline motor and during
starting and after stopping,  up to 30 percent CO can be
emitted.  Thus,  during 1939-1944, 41 fatal cases of
accidental generator gas  pois oning were registered.  At
this time,  chronic generator gas poisoning quickly be-
came the most common occupational disease in Sweden,
but declined after the war when  the use of generator gas
declined.   Then,  the danger of CO  poisoning from faulty
chimneys and the burning of inferior fuels became of
widespread interest.  Experience with patients at the
Generator Gas Clinic in the  Sabbatsberg Hospital during
1941-1945 is discussed.  Symptoms of  1883 patients are
described.  Fatigue, disorientation, absent-mindedness,
and disruption of powers  of concentration were noted,  as
were headaches,  dizziness,  insomnia,  and apathy.  These
disruptions of perception often led  to traffic accidents;
such cases  with chauffers and bus drivers are noted.
Clinical and otoneurological findings upon examination
are noted.   Some patients became more sensitive to
alcohol. Occupational and medical insurance aspects of
CO poisoning,  especially occupational poisoning,  are
discussed.  Five cases are described in detail.

The characteristic odor of ozone is noticeable about 1
ppm below 4 ppm,  ozone induces non-symptomatic
effects,  such as a  10 to 20 percent drop in basal metab-
olism, reduced pulse  rate and marked drop in arterial
blood pressure in hypertensives (not in young persons or
in hypotensives).  At higher, symptomatic levels, the
characteristic symptoms appear:  substernal pressure,
or a feeling of oppression, but no irritation of the mucous
membranes.  The oppressive feeling disappears as soon
as the ozone level drops below 4 ppm.   Symptoms of the
higher irritant, but nontoxic levels are: cough, itching
of the nose and throat, aggravation of symptoms by
tobacco smoke, and general mucosal irritation.  This
irritation and sore throat may persist  for several days.
One source believes that ozone is  nontoxic to man in
levels up to 1000 ppm for a short period,  or 20  ppm for
long periods of exposure.  Occupational examples of
irritation by ozone are mentioned, specifically in  a test
laboratory of a factory for electronic insulators.

Sub-lethal doses of irritant gases will protect against
the formation of lethal pulmonary edema upon subsequent
inhalation of highly toxic levels.  Groups  of 20 Wistar
rats each were pretreated for 6 hr  with low levels  of
phosgene (1 ppm),  NO£ (20 to 40 ppm), or ozone  (1.6 to
20 ppm) and four days later were exposed for a half-hour
to lethal levels of one of  the three gases.   Survival rate,
survival time, and relative lung weights are used as
criteria of protective effects  for the pre-treated animals
and for the  controls.  Ozone protects against subsequent
ozone exposure,  and also slightly against subsequent
NO2 or phosgene exposure.  NO£ protects  against itself
and ozone; pretreatment  with Phosgene produces the
most powerful tolerance  increases, specifically, and in
ascending order, to phosgene, ozone,  and NO^.  Pre-
treatment with NO2 is without any definite  effect on
phosgene  poisoning.  Since the protective effects are thus
not specific for one kind  of gas,  an  antigen-antibody re-
action is ruled out.   The  large variations  in degree and
duration of the protective give rise  to the  belief that
several unknown processes are involved.

ATTEMPTS AT THE QUANTITATIVE DETERMINATION

Using suitably buffered media so that the number of
living Escherichia coli would  otherwise  remain constant,
the effects of 0. 06 to 0. 40 mg/1 chloride and of 0. 11 to
0. 33 mg/1 ozone upon the survival of the bacteria were
observed.  The  apparatus is described for the administra-
tion of ozone  to  one-liter suspensions  of the  bacteria for
5 to 15 sec.  The number of surviving bacteria in a. cer-
tain number of hours after exposure to chlorine is graphed.
Because of the variable  decrease in chlorine content as  a.
result of varying initial  bacterial counts, the time curve
for lethality is  steeper for a small number of cells in the
initial suspension than for larger numbers.  The lethal
effect is accelerated by higher temperatures; the same
result is achieved at 37° C in about half the  time required
at 22° C. The extraordinarily quick action of ozone,  600
times that of chlorine,  may reflect a different mechanism
of action.  Since the time for  total killing of a bacterial
suspension is so brief, the situation cannot be the result
of a microphysical impact effect.  It is possible that
ozone can induce a general effect,  rather than some
selective effect to the vital centers.

are graphed.  Survival time was about 5 hr.  The effects
of nembutol, morphine,  largactil,  lobeline, adrenaline,
and digitalis are also noted.  The many  characteristics
common to poisoning with ozone  and with oxygen lead to
the conclusion that an identical mechanism is involved
in both cases.

An 8 m3 exposure chamber and auxiliary equipment are
described for use in exposure esperiments.  After a re-
view of the effects of low levels of SOz,  nitrogen oxides,
and O3  on human beings, work is described using groups
of 10 to 14 male volunteers. SO2 was smelled and/or
tasted by subjects at  0. 5 ppm,  by 75 percent at 1. 0 ppm,
and by all at 2. 5  ppm; 5 ppm reproduced cough and irri-
tation.  The initial odor slowly  changes  into a sensation
of flavor.  Increased humidity has no effect on the sensa-
tions.   The olfactory threshold  lies  below the lowest
tested  concentration of 0. 02 ppm.  Odor perception
diminished rapidly and 0. 5-12.0 min. exposure to 03
no longer led to an olfactory perception. Increased
humidity also has no  effect on perception. NC>2 is
smelled by some at 0. 1 ppm,  and by all of 0. 4 ppm.  The
olfactory sensation disappears upon continued inhala-
tion of higher levels  (up to 20 ppm) for several minutes.
Local irritations appeared during initial exposure to NO^,
but subsequent exposures  led to rapid adjustment.
Increased humidity with 1  ppm NO2  increases the num-
ber of irritant  symptoms.   A rapid  increase in the
threshold of perception to  relatively strong NC>2  levels
is observed. Results, including subjective effects, are
tabulated.

In order to explore the effects  of chronic CO poisoning,
rats, guinea pigs, and rabbits  were exposed in an air-
tight, 2 m  cage.  Exposures lasted  6 hours, and were
repeated daily, five times a week.  Resultant effects on
COHb levels and on electroencephalograms are noted.
The exposure system used is flow-charted.  Exposure
to 250-450 ppm CO led to a slight rise in COHb levels
(up to 4 percent),  which fell 12 hours later.  Blood cells
were normal; slight disturbances in serum protein levels
were found. Slight disturbances in electroencephalograms
are noted.

 COHb levels were measured in 302 patients: 46 with
 diabetes, 66 with gastrointestinal and hepatic disorders,
 38 with anemia,  30 with cardiac conditions, 74 with
 respiratory ailments, and several with occupational
 diseases  (24 with caisson disease and 14 with lead poison-
 ing).  Readings were  compared with those from 100 nor-
 mal subjects, with breakdown by smoking habit.  In only
 a very few patients with uncompensated cardio-circula-
 tory disturbances or respiratory diseases was  any in-
 crease in COHb level noted.  The high levels in these
 particular morbid conditions are attributed to incomplete
 CO elimination through the lungs, -with a consequent
 build-up in the blood, rather than, as others have pro-
 posed, to oxygen  insufficiency, with consequent failure
 to oxidize carbon to carbohydrate.  Thus, the presence
 of CO in the human bloodstream is considered to be of
 foreign origin, not endogenous.  The wide variations
 observed simply reflect heavier absorption or lowered
 elimination as a  result of individual or environmental

The results of experimental examination of memory
are  reported for a group of 44 patients  recently recov-
ered from acute and subacute poisoning.  Average age
of the patients was 35. 6 yr.   The following methods
were used; repeating 20 separate words, identification
of the same material from a  group of 10 expressions,
and  repetition of 30 verbal pairs having related meanings.
Disturbance of logical memory and difficulty in differen-
tiating were found; mechanical memory was relatively
intact.  When evaluating the result,  pathological changes
of the memory structure were found in  26 patients (59. 9
percent).  These findings were most frequent in the group
of industrially exposed patients, although loss of  con-
sciousness was  noted  in only 21.6 percent.  About half of
the suicidal patients (54. 5 percent), who had all lost  con-
sciousness, exhibited pathological deviations,  asdidmost
persons (47.7 percent) who had suffered from acute,  ac-
cidental poisoning (loss of consciousness in 36.8 percent).
When CoHb  levels  upon admission were compared with
the degree of  decreased logical memory in 22 patients, a
positive correlation was found.  At CoHb levels up to
29. 9 percent,  disorders of memory were found in 33. 3
percent; at levels of 30-78.3 percent CoHb, disorders of
memory were found in 61. 5 percent. Repeated exami-
nations indicate that,  with time, logical memory and rec-
ognition returned to normal and that mechanical memory
remained the  same (virtually normal).

The modifications of excitability-duration curves after
acute occupational CO intoxication in seven persons are
characterized by pronounced hypoexcitability of the
nerve and consequent inversion of the nerve-muscle
excitability ratios. Such modifications have already
been observed by many authors in states of fatigue, in
reduced resistance after surgery,  and in chronic alco-
holism.  The inversion in this excitability ratio appears
to indicate that the subjective clinical syndrom of mus-
cular asthenia with weakness  in the lower legs, custom-
arily observed after acute intoxication by CO can be
considered as an  objective clinical symptom.

A study was made of fibrinolysis in animals acutely in-
toxicated  with CO. The increase in fibrinolysis  is found
only in vivo, and is found  even in animals whose supr-
arenal glands have been removed.  The removal of the
spleen, however,  prevents the occurrence of this pheno-
menon.  Two hypotheses are advanced:  release  of "hypo-
xylienin"  can lead to hypocoagulability, or immission
into the circulation of splenin B,  a principle with profib-
rinolytic activity, can lead to fibrinolysis.

Tests which should be employed to judge the relationship
between subtoxic occupational CO levels and illnesses of
the workers are listed.  Workers in a blast furnace
workshop were observed for two years.  They showed no
unusual  irritability due to the monotonous noise (90 phon.)
in the shop until a defective machine  released small
amounts of CO.  Increased sensitivity to noise was  then
found,  as well as increased psychic irritability. Inquiry
at home showed that the workers showed increased
sensitivity to noise accompanied by insomnia.  CO tests
yielded 10-20 percent COHb at the end of a shift.  Audio-
gram of an older worker showed a clear loss in the
higher tones, and  others had lost 1500 Hz with a small
proportion of the loss in the higher tones.  Electroence-
phalograms exhibited variations, even in the  younger
workers.  Six weeks  after the equipment was repaired,
tests on the younger workers were normal.  Recovery
in the older workers  was  not complete,  even  after 16

 VENTILATION AND DISTRIBUTION OF AIR IN THE

 Data on ventilation, residual volume, and distribution
 of air in the lungs are assessed as a. group of patients
 with chronic bronchitis with emphysema.  The criterion
 for  classification into the two groups was the  result of the
 pneumotachogram or the epinephrine test.   Ventilation
 and distribution deteriorated considerably in the patients,
 compared with controls,  and provided evidence  that
 emphysema in these pathological conditions  is the main
 pathogenetic factor  of dyspnea.   The asthmoid component
 reduced the respiratory function even more  markedly,
 but this deterioration was not sufficient to manifest it-
 self significantly when evaluated statistically.

 In experiments on five anaesthesized rabbits, vagotomy
 was found to aggravate ozone-induced edema.  It is
 pointed out that ozone  intoxication is not the only pheno-
 menon which can produce tachypnea with reduced volume,
 associated with alveolar edema.  Embolism of the  pul-
monary artery by small particles is one example.  Super-
ficial respiration can also occur in the absence of edema-
 tous infiltration of the lung, as  in the case of anaphylactic
 shock in the  rabbit.  However,  polypnea in the rabbit
 induced by ozone is  intense  and stable as long as the
 vagal nerve remains intact.

EFFECTS  OF AIR POLLUTION ON HEALTH.   REPORT
NO.  1:  ON PEAK FLOW RATE AND VITAL CAPACITY
OF PRIMARY SCHOOL CHILDREN.   Translated from
Japanese.  Report of the Osaka  City Institute of Hygiene
(Osaka), Vol. 26, p. 32-37,  1964.   18 refs.

The effect  of SO2 and dust pollution in an industrial area
of Osaka, Japan,  on the pulmonary function of school
children was investigated.  Peak flow rate and vital
capacity measurements  of 275 children from two schools
in the city  were compared with those of  150 children of
a rural area.  At the same time a questionnaire survey
elicited data on the childrens1 respiratory health, and
the school  health records were used for height and
weight measurements.   Dust count and SO2 concentra-
tion data were obtained concomitantly.   Children from
one of the cityschools, in the most polluted area, showed
a tendency toward delay in the peak flow rate increase
due to growth,  in parallel with a high dust count and SOz
concentration in their area; a remarkably high percent-
age of these students showed a peak  flow rate of less
than 250 liters/min with a. vital  capacity ratio of more
than 80 percent,  differing significantly from the other
two schools.

In a study of 1010 healthy outdoor electricity supply
company workers,  the relationships between peak flow
rate,  number of cigarettes smoked per day, and years
spent in smoking were investigated statistically with
age and height taken into account.   The peak flow rate of
the habitual smoker was  lower than that of the non-
smoker.  The peak flow rate of heavy smokers with o.
smoking habit of 10  years or longer duration was signifi-
cantly lower than the peak flow rate of those who had
smoked 5 years or less;  this difference was not true of
light smokers (10 cigarettes or less per day).

CO poisoning due primarily to the widespread use  of
temporary primitive stoves for heating apartments and
offices during the 1941-1943 siege of Leningrad, is
reviewed.  The  studies are based on 1020 cases  of
which 256 were  hospitalized.   The majority of cases
•were severe and mortality "was relatively high.   The dis-
cussion, supported by tables,  covers clinical symptoms
observed,  including an incidence of concomitant  pneu-
monia in 34 percent of the hospitalized  patients,  blood
examination for  carboxyhemoglobin,  severity of poisoning,
and course of the intoxication, illustrated by specific
cases.  The pathogenesis of the CO poisoning during these
war years viewed as different -with respect to factors  such
as alimentary dystrophy,  psychic and neurological condi-
tions.  A synergistic  action of the toxic gas and the un-
favorable course of the CO poisoning in many of  the
patients.  Problems of therapy, including blood trans-
fusions,  are illustrated by sample cases. Group poison-
ing episodes indicated that various persons exposed to
similar CO concentrations had different  amounts of COHb
 in their blood.  Degree of poisoning was not always
 correlated with amount of carboxyhemoglobin.

 seem to cause  sufficient damage to limit the field of
 comfortable social hearing.  Exposure of CO does,
 however,  cause irreversible alterations of the vestibular

The effect of carbon monoxide poisoning in rabbits on
quantitative changes  in protein serums was studied
experimentally, using two animals in each of three
three-month series.   Analyses included  total protein as
well as the separate  albumin and globulin fractions
(gamma, and  alpha-beta globulins).  Very significant
temporary  changes in amounts  of albumin fractions  were
observed at variable periods -  in most cases favoring
a parallel increase in alpha-beta globulins.  The result
is an inversion of the albumin/globulin ratio which is
variable in duration and is a function of the carbon mono-
xide dose administered.  The series of rabbits which
received 250 ppm CO, showed their albumin/globulin
inversion of the 53rd day and it lasted one week; the
series which received 450ppm,  in contrast showed an
inversion on the 25th day and it lasted much longer,
about three weeks. This reactive intervention of humoral
protein is so effective, that it causes the original equili-
brium to be re-established, and even exceeded.

shows that for an average traffic exposure of 2. 5  hr
between May and August,  1964, the  average COHb level
rises from 0.93 to 1. 10 percent.  This increase  is
greater for persons with 3-4 hr exposure than for per-
sons with only two hr.  Air measurements indicate a
range  of 5-15 ppm during periods of high traffic activity.

To obtain early recognition of slowly developing  chronic
CO poisoning in a gas works, complaints from 51 exposed
workers were collected and audio-metric and vestibular
function tests performed.  Occupational exposure was
to 0. 01 percent or more CO.  Compared with a group
of controls, subjective complaints of the CO-exposed
group amounted to 84 percent compared to 47 percent

As  part of a review of hemoglobin types and hemoglobin
anomalies, the formation of COHb is mentioned as a
very important alteration of the hemoglobin.  COHb is
bright red and has  absorption lines in the spectrum at
568 and 539 )j..  The clinical symptomalogy is provided.
Permanent damage may result from COHb levels  above
20  percent, and for that reason 20 percent has been
called the toxic  limit.

The hearing of 35 patients up to seven years after CO
intoxication was tested.  In 31 patients,  the audiometric
curve for both sides took on the shape of a U of varying
size,  corresponding in each case to the  degree  of loss  of
hearing.  The greatest loss of hearing took place at 2048
Hz.  The U-shaped curve occurs rarely in the general
population, but has been noted in children born  in asphyx-
ia and in children whose mothers came down with measles
during pregnancy.  It is  concluded that the U-shaped
curve is often observed in CO intoxications because of
damage to the central  organ of hearing.

Mineral metabolism investigations on the heart and
skeletal musculature of 50 rats,  of which  10, were
intoxicated with HCN,  CO, N^, or CO^, revealed that
the heart musculature and the  skeletal musculature be-
have in opposite ways.  After CO intoxication the  intra-
cellular potassium content of the skeletal musculature
drops; on the other hand,  it remains  constant in the
heart muscle.  On the other  hand, HCN, CO2, and N£
lead to a reduction in the  intracellular potassium  of the
heart musculature at unchanged potassium content in
the skeletal muscle.  The causes  for this are discussed
in terms of oxygen shortage.

EFFECT OF CHRONIC CARBON MONOXIDE INHALA-

EXPOSURE.  Translated from Russian.  Gigiena  Truda
i Prof.  Zabolevaniya (Moscow),  Vol.7, p. 54-55, June
1963.  12 refs.

Chronic  inhalation (2 hrs/day for 15 days) of carbon
monoxide in concentrations,  e.g.  2 mg/1,  which elicited
CO intoxication,  lowered the resistance of white mice
to X-ray irradiation.  In contrast,  chronic 0. 01 mg/1
inhalation of CO in nontoxic concentrations e.g. 0.01
mg/1 by white rats (sic), had no effect on the animals'
resistance,  even when carried on for 60 days.  Para-
doxically, when the dose of CO was reduced  to 0. 005
mg/1 two hours daily for 60 days, the experimental
animals' resistance was enhanced.   This enhanced re-
sistance  to X-rays seems in no way to be connected with
the hypoxemic mechanism of CO action reported by other
authors,  since the degree of hypoxemia in test and con-
trol mice was the same,  1. 5 percent.

cussed.  Observations in recent years at the Institute
of Industrial Hygiene and Occupational Diseases of the
Academy of Medical Sciences of the USSR showed that
the so-called "lead kidney", as well as "early  arterio-
sclerosis" in workers who come in contact with lead
"belong to  the past".  In fact,  in a considerable number
of workers examined, a tendency toward a lowering of
the level of maximal arterial pressure was  noted, with
the number of cases of hypotension proportional to the
increase in degree of poisoning.  Oscillometric data did
show an increase in mean arterial pressure (and also in
venous pressure) in some of the individuals examined.

The  role of acidosis as a manifestation of chronic, as
well as acute carbon  monoxide  intoxication was  studied
with two series  of rabbits,  one of 20 and one of  30
animals.  After elimination of the more susceptible
animals, a  concentration of 0.25 percent CO was used,
with an inhalation time of 1-1/2 hours  a day.  The re-
serve alkali index of  the plasma,  determined manomet-
rically, was affected significantly by the state of hunger
of the animals.  However, these determinations as well
as cholesterol determinations proved unsuitable for the
detection of chronic carbon monoxide intoxication.  De-
finite changes were observed,  however, upon determi-
nation of erythrocyte resistance,  and of the serum phos -
phatide value.  The paper is carefully documented with
specific data, tables and figures.

Sufficiently significant variations  in fasting and normal
rabbit blood sugar levels,  determined by the Hagedorn-
Jensen method,  were observed  to suggest abandonment
of the assumption that mammalian blood sugar content
under physiological conditions is a. constant and species-
specific  quantity.  Similarly, in animals exposed to
carbon monoxide variations up to  50 percent were noted.
This fact limits the significance of about 50 determi-
nations in -which experimental CO-exposed animals
showed a mean blood sugar value  of 124mg percent  and
showed a mean blood sugar value  of 124mg percent and
control rabbits a mean of 106mg percent.  It may be as-
sumed however that carbon monoxide did influence blood
sugar regulation.  Additional studies, involving glucose
tolerance tests, are discussed in  detail,  to show the ef-
fect of CO on the blood-sugar regulating organs,  such
as the  suprarenal gland.  An unexpected reaction of a
control animal indicated that a particularly high,  or
somehow abnormal, blood sugar curve is  not one of the
detailed  manifestations of chronic CO poisoning.

observed.  It  is concluded that carbon monoxide acts on
the nervous tissue causing degenerative changes; and
that a. relative selectivity of the toxin in regard to a few
cerebral regions seems to be a result of a particular
biochemistry  of the respective cerebral regions of the
whole brain due to which the nervous tissue has  an un-
equal resistance to the action of the gas.

 methods.  The following five methods can be used:  (1)
 the spectroscopic test which is a. qualitative test  and in-

 (2) The Wolff test, a quantitative method based on hemo-
 globin precipitation while  COHb remains in solution,  (3)

Experiments with rabbits who were exposed to CO-air
mixtures in gas chambers for 1/2 to 1 hr showed that
the blood sugar level increased above normal and was
maximum about 1/2 hours after exposure.   Then after
2-1/2 hours the blood sugar level decreased to normal.
A marked increase in blood sugar was found even in
cases when the COHb content amounted to only 20-25
percent.  Experiments with nitrogen-oxygen mixtures
showed that even under severe anoxemia no rise in
blood sugar was noted.  Therefore,  the increase in
blood sugar level  is due to the specific effect of carbon
monoxide and not  to the lack of oxygen.

Industrial and clinical physicians disagree as to whether
there is such a thing as chronic  carbon monoxide poison-
ing.   Opponents of the notion contend that the pathophy-
siological mechanisms during exposure to CO do not
correspond to those of "true" chronic poisonings.  Sup-
porters of  the concept insist that it is based primarily
on practical, clinical results . Examples  are presented
which suggest that the terms  "acute" and "chronic" can
both be applied to the following phenomena:  exposure
time to the damaging agent,  the  developmental phase  of
the disease, the course of the disease, secondary phe-
nomena,  and therapeutic  measures. Other sections of
the paper discuss (1) recent knowledge concerning  clin-
ical symptoms of chronic CO poisoning, (2) recent ex-
perimental results concerning the effects  of CO,  (3) the
pathophysiology of chronic CO poisoning,  and (4) the
diagnosis of chronic  CO poisoning.  It is concluded that
there is no need to eliminate  the term "carbon monoxide

0. 005 percent of CO were  measured in the apartment,
but based upon figures  quoted from V.  Raymond and A.
Valland, it is concluded the wife's illness would have
required at least a 0. 01 percent concentration  of carbon
monoxide to cause symptoms of dizziness, mild dis-
turbance of consciousness, pressure in the heart region,
anxiety,  palpitation, and anoxemia.  While symptoms  of
this kind occur in carbon monoxide poisoning,  they do

At two German border crossings for private cars,  the
CO content of the air was measured.  Average concen-
trations were 0. 013 Vol percent, with peaks of 0. 022
Vol percent.   A statistically significant correlation was
established between traffic rate  and air CO content. The
health complaints of the passport and customs officials,
which had been observed for several weeks, showed a
statistically significant correlation with traffic rate and
wind velocity.  When the traffic rate was equal,  the com-
plaints decreased when the wind velocity increased. This
correlation could also be quantitatively determined by
means of the regression line.  In  several of these of-
ficials,  the blood COHb was  determined before,  during,
and after the period of duty.   During duty, increases  of
an average  of 10 percent could be found with maxima  of
14 percent COHb.  There is  no doubt that, in conditions
of heavy traffic and no wind the officials  at the two
border crossings are endangered  by the exhaust fumes.
Evidently the complaints are attributable to  the effects
of several components  of the exhaust fumes.  Appropriate
countermeasures are suggested.

The carboxyhemoglobin content in blood of animals with

were compared  to evaluate the sensitivity and reliability
of the individual methods.  The three methods developed
by the Departments  of hygiene and biochemistry at the

 The effect of aeroionization on the immunobiological re-
 activity of the  organism during chronic carbon monoxide
 poisoning -was  studied with 52 albino rats. One group
 was exposed to carbon monoxide only, another group ob-
 tained 30 min. of aeroionization after  carbon monoxide
 poisoning and  the third group served as control.   Before
 the experiment all animals were vaccinated three times
 at 7-day intervals with killed typhoid vaccine.  The re-
 sults showed that the hemoglobin content was 75-85 per-
 cent in all three groups.  The agglutinin titres were
 maximum in all three groups on the 23rd day after the
 third vaccination.  The agglutinin titre in the poisoned
 animals "was 2. 5  times lower than in the control group
 and 3 times lower than in  the group treated with aeroions.
 Thus, the use  of  aeroions neutralizes  the effect of carbon
 monoxide and  aeroionization has  a. favorable effect on
 chronic carbon monoxide poisoning.

 This review of the general properties of carbon mon-
 oxide poisoning and its temporary and possibly chronic
 effects upon the central nervous and cardiac systems
 utilizes many reports of other  investigations and of 30
 individuals whose work involved exposure to carbon mon-
 oxide.  In some cases,  symptoms of chronic carbon
 monoxide  poisoning may progress even after contact with
 this toxic  agent is discontinued.  Over half  of the subjects
 presented overt electrocardiographic changes indicative
 of muscular changes.  Symptomatic treatment is given
 for  cases  of chronic carbon monoxide poisoning,  but
 investigations of other forms of treatment,  i.e. iron
 preparations  and novocaine, should be made.

 The activity of choline esterase in the presence of carbon
 monoxide was  studied to elucidate the mechanism of
 carbon monoxide  poisoning and find a diagnostic method
 for determining early carbon monoxide poisoning.   Al-
 bino rats and guinea pigs were subjected  to chronic or
acute carbon monoxide and the activity of choline esterase
in the brain, heart and liver was determined.  The choline
esterase activities after acute and chronic poisonings
differed considerably.  Determination of the choline
esterase in the blood of guinea pigs in chronic and acute
experiments  showed that the  choline esterase activity is
a sensitive indicator of carbon monoxide poisoning.  Its
determination is  therefore recommended for hygienic
and toxicological purposes. The chronic action of carbon
monoxide showed also that it directly affects the cells
and that it may have adverse effects even in very  low
concentrations.

Based on the results  of a long study of the carotid body
a hypothesis -was developed which explained the nature of
reflexes originating from carotid chemoreceptors. The
reflexes caused by anozic poisons  (cyanide, sulfide),
poisons suppressing the respiratory phoshorylation,  and
by carbon monoxide -were studied.   The experiments
showed  that carbon monoxide is a. strong stimulant of
carotid  chemoreceptors.  It was shown that stimulation
of chemoreceptors causes reflexes acting on the adrenal
gland.  The effect of nicotine on blood pressure was also
found to be caused by reflexes originating from carotid
chemoreceptors.

The effect of air pollution on human health was studied
by determining the dust fallout  and its sulfur content in
several German municipalities  in the Ruhr region.  The
serum phosphatase activity of 503 boys in the Oberhausen
area was  determined.  Also hemoglobin values and red
blood cell counts were determined in  1805 boys,  and
lung cancer mortality figures were studied.  The results
confirm previous  conclusions that the children in pol-
luted areas exhibit higher phosphatase values,  and an
impaired  blood count, indicating the possibility of long
range damage due to increased  light absorption.   The
lung cancer mortality in Oberhausen increased in 1952-
1959 from 30 per  100, 000 to 50 per 100, 000, thus ex-
ceeding values reported in the U. S.   It is proposed to
record lung cancer and leukemia mortality throughout
Germany,  in order to establish data baselines  for
individual communities.  Air Quality  measurements  of
dust and sulfur (in terms of 504) are  tabulated and dis-
cussed.

Inhalation tests were conducted on 25 healthy males to
determine  their response  in pulmonary airway resistance
to the interaction of aerosols and irritant gases.  The
subjects were divided into 3 groups.  Group  1 inhaled
SO2 for 5 minutes, followed by a mixture of  SOz with a
large-size NaCl  aerosol.  Group 2 inhaled NO2 for 5
minutes, followed by a small-size NaCl aerosol.  Group
3 inhaled NO2 for 5 minutes followed  by a mixture of
NO2 and a  large-size NaCl aerosol.  The airway resist-
ance  (AWR) values immediately after inhalation were
measured by the  airway interruption technique,  and the
intensities of the  reactions were compared.  The control
values for  the AWR were those prior  to the tests.  The
AWR increased synergistically in groups 1 and 3.  In
Group 2 the AWR for NO2 and NO2  plus aerosol was
higher than the control value,  and practically no change
in reaction was observed when the NO?  •was mixed with
the NaCl aerosol. The synergistic effect of an  irritant
gas and an inactive aerosol is greatest when the  aerosol
particle size is around l[i, and the  increase  in airway
resistance in this case is  believed to  be  due  to reactive
constriction of the respiratory bronchioles and alveolar
ducts.

The effect of lignite coal dust and ash in the Hashirskly
Electric Power Plant near Moscow on the health of ex-
posed workers was studied.  A total of 148  workers •were
examined.  While dust pollution of lungs can occur after
only 5 years of -work in a power plant, the development
of actual pneumoconiosis is considered to require ex-
posure of at least 20 years.  It was found that carbon
dust and ash from lignite coal originating in the vicinity
of Moscow penetrate the pulmonary tissue to cause re-
active changes characterizing pneumoconiosis. Clinical
details on various sub-groups of the workers, including
X-ray findings, are mentioned.  The harmful component
in both the coal and ash dusts is silica which is present
in large amounts.  The presence of sulfur anhydride in
household dust requires further study. Based on  the
dust particle concentration, the pollution even in  the
most hazardous areas of the electric plant is considered
moderate.  Only 4 cases of pneumoconiosis •were  found
after 10 years of service.  Future studies on the  effect
of dust on children are indicated,  on the basis of  incon-
clusive findings on 19  children living in the area.

Investigations of the atmosphere in Shebekino  have
revealed it to be intensely polluted up to a radius of
3 km from a synthetic fatty acids and alcohol plant in
the Shebekino Industrial Complex. Its discharges con-
tain fatty acids, hydrocarbons, acetone,  methanol and
formaldehyde.  Investigations showed that combustion
of exhaust gases occurred at  low efficiency, with hydro-
carbons,  acids and acetones only 30 percent burned.
The concentrations of pollutants  in escaping gases, and
of saturated and unsaturated hydrocarbons, ketones,
acetone, and fatty acids in atmospheric air, are tabu-
lated.   Construction inadequacies of the furnace used
were blamed for the low efficiency of combustion.  A
complete medical examination of the children  in Shebe-
kino shows their health to be  somewhat affected by the
atmospheric pollution.  Diseases of  respiratory tract
prevail  among other affections.  It has been determined
experimentally that the threshold value of olfactory pre-

Studies of chronic respiratory diseases  related to air
pollution carried out by fourteen study groups are re-
ported.  Clinical and pathological phenomena of respira-
tory diseases  for two areas with high pollution levels
(Tokyo and Osaka City) and a non-polluted area (Nara
Prefecture) are compared.   Respiratory symptoms were
studied in long time residents of the areas studied in
employees of commercial enterprises, and in inmates of
homes for the aged.  Clinical and pathological examina-
tions  were also made of patients being treated by medi-
cal organizations.  Soot accumulation in the pulmonary
tissue and pathological changes were investigated in the
bodies of accident victims based on area of residence,
age, and sex.   Specialists in different areas  observed
levels of air pollution and found a clinical and pathologi-
cal relationship between soot accumulation in pulmonary
tissues and  the occurrence  of chronic bronchitis, pul-
monary emphysema and pulmonary fibrosis.   While  the
different study groups did not investigate identical para-
meters and  patient-groups, their observations generally
agreed in correlating the  respiratory conditions found
with the presence of air pollution in Osaka and Tokyo.
Clinically, the incidence  of chronic bronchitis  seemed
high,  as did both the incidences of pulmonary emphysema
due to abnormal ventilatory function and pulmonary
fibrosis observed in x-rays.  In one study of subjective
respiratory complaints, lowering of ventilatory function,
and abnormal  linear shadows, no such difference as
that found between (the non-polluted) Nara Prefecture

 The morbidity of the population in Leningrad from dis-
 eases of the respiratory organs was studied.  Material
 was collected from 7 polyclinics which serve as much as
 10 percent of the population and "which are situated in
 regions of the metropolitan area differing in degree of
 air pollution  (from clean air, expressed as "up to 150
 g/m3/yr  of sediment" to strongly polluted air, expressed
 as "up to 700 g/m3/yr of sediment".)  A comparison of
 the results by statistical processing of the morbidity
 data with data concerning the degree of air pollution,
 indicate that  this morbidity of the population in the
 microregion with polluted air is higher in an average of
 90 percent of the cases  than it is in the microregions
 with clean air; for angina,  it is 2 to 3  times higher, for
 bronchitis, 3 to  5 times, pneumonia, 2 to 3 times, pleu-
 ritis,  3 to 4 times, and for diseases of the pharynx and
 tonsils, 5 to  6 times higher.

In order to elucidate the mode of effect of irritant  gas,
the mechanism of a tolerance increase was studied,  as
it develops following the effect of  small gas concentra-
tions.  This effect, which is  known for phosgene and
ozone, was  determined also for nitrous gases.  These
three gases exert a protective effect of differing inten-
                                                            sity with respect to each other with the exception of the
                                                            combination of nitrous  gases and phosgene.  This pro-
                                                            tection is consequently neither a principle valid for all

                                                            one type of gas.  This finding permits exclusion of an
                                                            antibody-antigen reaction as the mechanism involved.

Dry cell factories utilize large amounts  of pyrolusite
(MnOz).  Very volatile Mn compounds are liberated in
the grinding of the pyrolusite in the mills, exposing
workers at the mixing machines in such  plants to inhala-
tion of the dust in the mixing operation.   Two case his-
tories  of confirmed  Mn poisoning in two  different fac-
tories  are presented. The first patient showed symptoms
of Mn poisoning only after eight and a half years of work-
ing as  a pyrolusite mixer, while the disease erupted in
the second patient after twenty-one months in this occu-
pation.  The  significance of  the demonstration of Mn in
stool and urine and the importance of pneumonia among
pyrolusite workers are discussed.

The sensitivity to mycotic flora on the part of Vietna-
mese asthmatics was investigated by examing 61 asthma-
tic patients plus a control group of 45 healthy individuals.
An infectious allergic type of  asthma was determined in
the majority of cases (88. 5 percent) as well as  frequent
sensitivity to mycotic flora (in 55. 7 percent an  allergy
to mold fungi was found.) In the control group of 45
healthy individuals, sensitivity was  significantly less
common, while a finding of sarcinae in the respiratory
passage  was equally frequent  for both asthma patients
and healthy individuals.  A serologic examination per-
formed on half of the asthma sufferers and healthy sub-
jects indicated the presence of complete antibodies
against sarcinae to be  considerably more frequent in
asthma patients and only in isolated cases and in posi-
tive titer threshold values in healthy subjects.  The use
of mycotic antigens  for treatment  is recommended.

OBSERVATIONS ON MANGANESE PNEUMONIA.
[Beobachtungen liber Manganpneumonien.J  Translated
from German.  Eighth International Congress on Indus-
trial-Accident and Occupational Disease.  Leipzig, No.
2, p. 1014-1022,  1939.

In the vicinity of a plant for the production of manganese
oxides in Sauda, Norway,  analysis demonstrated con-
siderable amounts of  MnO^ in the air.  Since the estab-
lishment of the factory, the community has become
known for the high incidence of lobar pneumonia.   Morta-
lity in relation to the number of patients is  also unusually
high.  If the total production of the plant is  related to
Mn content  of the air, it is shown that morbidity from
lobar pneumonia in the community varies with the  total
production.

Known formerly for its healthy climate, the town of
Sauda, Norway, since the start of industrial activity
has had a pneumonia morbidity four times that of the
whole country and a pneumonia mortality eight times as
great.  32. 3 percent of all decreased in the district
since 1924 died from this disease.   The industrial pro-
ducts of the area are alloys of manganese produced by
electrical melting.  This operation gives off a consider-
able amount of smoke.  The smoke contains Mn and an-
alysis of lung tissue from dissected individuals shows a.
considerable increase in Mn content.  It is concluded
that the abnormal pneumonia conditions must be  due to
the exposure of the inhabitants,  through the factory
smoke, to the inhalation of the Mn dust.

SOME DATA ON THE INFLUENCE OF CONTINUOUS
AND INTERMITTENT EXPOSURE TO CARBON MONO-

A comparative study  was made of the effect on labora-
tory animals of intermittent and  continous exposure to
carbon monoxide. In the intermittent experiment animals
were exposed 4 hours daily for four months.  In the con-
tinuous experiments they were exposed to a constant
mean concentration of 0.036 mg/1.  A carboxyhemoglo-
bin content  of 15-16 percent was found during exposure
in rabbits exposed intermittently.  Twenty hours later,
i. e. prior to new exposure,  the carboxyhemoglobin
content was zero. Animals  continuously exposed to car-
bon monoxide did not exhibit any carboxyhemoglobin.
The gas  exchange was lower in mice continuously ex-
posed, while intermittently exposed mice showed no de-
crease in mean oxygen consumption.  The ability to
•work (swimming time)  of mice constantly exposed was
somewhat higher than of those intermittently exposed.
The overall conclusion indicates that fluctuating concen-
trations  of  CO are more harmful than exposure to a
constant mean concentration of carbon monoxide,  even
•with rare and transient elevation to a level inducing a
brief increase in carboxyhemoglobin content in the blood.
When evaluating the toxicity of carbon monoxide inside
Industrial buildings,  the concentration fluctuations
should be taken into consideration.

 and one room in the children's home located in the same
 building hut in areas away from the boiler rooms  served
 as  controls.  The air in apartments located above boiler
 rooms was much more polluted by CO and SO^ than air
 in the control apartments.   The frequency of detection
 and the concentration increase during  cleaning of the
 boilers indicated that the boiler room  was the  source  of
 the pollution.  In order to study the effect of the air on
 the  carboxyhemoglobin level three groups of persons
 were examined: 22 janitors,  56 persons  who lived
 above boiler rooms, and 63 children from areas with  no
 stationary boilder  room. The tests,  adjusted for a 6 per-
 cent COHb level in all city dwellers,  showed that child-
 ren living in buildings -with no stationary  boiler had a
 carboxyhemoglobin concentration of less  than 6 percent
 in the overwhelming majority of samples. In persons
 living above boiler rooms the number  of positive sam-
 ples amounted to 34 percent.  Most of the samples with
 concentrations  above  6 percent were found in janitors
 (64 percent.)

 2. 5 times more  Mn was found than is found  in  normal

Two inhabited localities differing in intensity of pollution
by industrial -waste were investigated for the presence of
SO2-  The first locality was 2000 to 3000 meters from a
sintering plant and the  other 6000 to 7000 meters away.
The  zone 2000 meters  from the main source of emissions
was  polluted the most by SO^.  The concentration grad-
ually decreased in the  following zones.  Since the SO2 con-
centrations  in the air greatly exceeded the permissible
limits,  the  presence  of sulfur anhydride in  the Dlood of
residents was determined.  At the same time the con-
centration of sugar and ascorbic acid were  also deter-
mined.   To  supplement the chemical studies,  the people
were questioned about  the gas odor.  The results of the
biochemical analysis of the blood and interviews indi-
cate that SO2 is an unfavorable health factor,  especially
in the locality 2000 meters from the sintering plants.

 DUST ON PLANTS,  [liber das Problem der  Zement-

 STAUB, 22(6): 228-232, June 1962.  31 refs.

 The investigation of plants in the sedimentation area of
 several cement factories definitely proved the formation
 of cement crusts  on the leaves and needles  of a wide
 variety of plants.  In  other "words, it proved  the direct
 action upon the plants.  The lime  hydrate, "which is
 released during the setting of the  cement dust with the
 water on the surface of the leaf epidermis,  however,  by
 definition of the term toxins is a. very strong  caustic
 poison and, after penetration through  the stomas of the
 conifer needles or penetration of the upper  epidermis  of
 leaves that  only have  stomas on the  other side, directly
 corrodes the living content of the  leaf cells and thus
 directly damages the  plants (leaves).  A critical review
 of the literature  and the investigations described here
 tell us that  previous investigations using artificial
 mechanical dusting of cement preparations  over plants,
 under uncontrolled weather conditions, are not suitable
 for reasons of methodology and because of the selection
 of the location for the experiment; these methods are
 thus not suitable in answering the  question as to the
 direct effect of cement dust upon the plants in the
 vicinity of cement factories.   The action upon the
 soil is not discussed.

Two-year-old Satsuma (Citrus unshiu),  (C.  hassaku),
and Natsudaidai (C.  natsudaidai) orange trees were
fumigated with a continuous stream of air containing 5,
1, and 0 ppm of sulfur dioxide for  34 days,  2 hours per
day.  Defoliation increased with increasing  concentra-
tion of SO2, although smoke lesions did not  occur.  The
increase in sulfur content  of the leaves coincided "with
defoliation rate.  Hassaku and Natsudaidai leaves
accumulated more sulfur than Satsuma, but defoliation
rate was markedly lower than for Satsuma.   The calcium
content of leaves decreased considerably and potassium
content decreased slightly in  all species after fumigation
with 5 ppm.  In the growing season, from May to June,
1964,  the same  relationships  were observed, but sulfur
absorption was markedly higher than in the  "winter fumi-
gation,  in spite  of its shorter duration.  The calcium
content of leaves "was not clearly related to  the SO^
level  during the growing season, but the potassium con-
tent of fumigated trees "was higher than in controls.
Nitrogen, phosphorus,  and magnesium contents  were not
related to sulfur dioxide concentration.  In a later experi-
ment  using  a fumigation chamber,  trees were fumigated
with 2 ppm  (6 hrs),  10 ppm (12 hrs  ), 5 ppm (24 hrs), or
2. 5 ppm (48 hrs) for a cumulative total of 120 ppm SO2-
The higher  the SO^ level,  the more severe was the
injury to Satsuma trees.  Sulfur content of leaves,
however,  did not coincide  with injury.   Therefore,
analysis of  leaf sulfur content may be useful for evaluating
chronic injury,  but in acute injury it may not be useful.

 Relations between the possibilities  of combination in
 time of  given amounts of SO2 and plant reaction are
 clarified.   Continuous action is discussed and it is de-
 monstrated that the familiar "stimulation-threshold
 function" of L'Gara and Stratmann do not have general
 validity. They develop a new equation which  is better
 adapted to  the experimental findings.  Prerequisite for
 the  analysis of intermittent gas exposure is knowledge
 of the trace of the deterioration curve under continuous
 gas exposure.  The experiments  furnish the basis for a
 formula which represents the degree of deterioration  as
 a function of concentration and duration of action.  The
 effects  of continuous and/or intermittent exposure have
 a given  relation to each other.  The experiments with
 constant and variable exposure and interruption shown
 in tables and graphs demonstrated  that plant deteriora-
 tion becomes reduced as a function of the time of re-
 cuperation and duration of exposure.  The former is
 limited  by  a minimum time of recuperation and the
 latter by the threshold of stimulation. The sum of these
 individual findings is embodied in <± "recuperation func-
 tion" with the  help of which the plant reaction can be
 calculated  in advance from metrologically given data.

From 15 August to 25 September 1963 the activities of
the enzymes catalase, peroxidase, and polyphenoloxidase
in maple and birch branches  15-18 years old, were sub-
jected to 14 test fumigations  in a gas chamber with 50%
in concentrations of 2 x 10   and 2. 5 x 10.  The purpose
of the experiment was to test the thesis that the effects
of O-gases on photosynthesis and  respiration differ in
different types of plants   and especially that the  inhibi-
tion of dark reactions, but not of light reactions,  by SO^,
•will carry over to diverse  types of enzyme  systems.
Maple and birch were chosen because  not only does the
former have a weak reaction to damage and the latter a
strong one, but also because they differ greatly in phy-
siological, biochemical,  and  anatomical characteristics.
Catalase activity was  lower in the maple than the birch
by 32. 5 percent,  and similar differences were observed
with the other two enzymes.  (On  this  basis it is suggest-
ed that  the intensity of photodynamic oxidation must be
proportional to the activity of the  redox enzyme systems.)
SO2 depressed the  activity of all three enzymes, but
catalase was the most severely affected. The difference
in effect between the -weaker  and stronger concentrations
was that the weaker increased the enzyme activities on
the second day, whereas the  stronger  decreased it. Thus,
the SO2-induced drop in catalase activity may promote
oxidation processes and plant damage  through accumu-
lation of organic peroxides (Mikhlin, 1960), but nothing
definite can be said about peroxidase and polyphenoloxi-
dase without further testing.

Experiments with chlorella pyrenoidosa in an atmos-

inhibition of photosynthesis by carbon monoxide.  It was
found that cells grown in light show inhibition of photo-
synthesis by carbon monoxide.  Inhibition is reversible
and depends on the  CO and O^ partial pressures.  Also
the effect of the spectral characteristics of light on the
inhibition of photosythesis  was studied.  The experi-
ments indicated that in photosynthesis an enzyme is
involved which has  an effective group containing iron.
This enzyme transports  oxygen in photosynthesis.  Car-
bon monoxide inhibits photosynthesis by blinding the
iron in the enzyme.  The absorption spectrum of the
carbon of the photosynthesis was determined.  The
carbon monoxide compound can be  split by light and thus
inhibition is stopped.

ent plants.  Also the effects of short duration  exposures,
the importance of time intervals between exposures, the
effects  of duration of exposure and concentration, and
the combination of toxic and subtoxic concentrations
were determined. For a given amount of gas  an in-
crease  of non-exposure period and an increase in im-
pulse frequency of gas exposure were found to prolong
the threshold period after which irritation  occurs.
                                                                                                                71

 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 recuperative
 pauses within certain ranges of concentration. The
 plants were divided into the  following groups according
 to their resistance as well as their tolerance:  (1) clover
 type cattle feed.  (2) cereals, and (3) rape, cabbage  etc.
 Individual SC>2 immissions cannot be treated by a simple
 additive process in the determination of gas effects  on
 plants.  The manner of their distribution over the diurnal
 period must be taken into account, along with biological
 and meteorological factors.

 Experiments were conducted with the tree  species
 Populus nigra and Prunus laurocerasus to  determine
 unfavorable changes in the balance between synthesis
 and dissimilation of dry matter at elevated temperatures
 induced in the leaves by foundry dust  deposition.  The
 increase  or loss in  dry weight were determined by the
 modified  leaf half method  (increase in weight).  The
 results showed that foundry dust deposited on leaves
 causes a reduction in the expected increase in dry matter
 after seven hours of exposure.   Removal of the  dust
 deposit resulted  in an immediate increase  in the produc-
 tion of dry matter.  Prolonged dusting was found to
 cause a decrease in productivity as well as a permanent
 reduction of the total leaf  weight and starch formation.
 An increase in temperature of the leaf tissue was found
 due to the absorption of heat rays of solar  irradiation by
 deposited dust.  Details of the test results  are tabulated
 and analyzed statistically.  It was established that the
 difference between the increase  in dry matter in the
 clean and contaminated leaves increased in proportion to
 the temperature  elevation, a  change evident even at a
 temperature difference of 2. 5 percent C, the average
 heating power of the dust used.   Simultaneously an in-
 crease in the intensity of dry matter reduction,  or  re-
 spiration, occurs.

 THE EFFECTS OF FOUNDRY DUST FROM THE NOVY

 Musei Silesiae, Series  C,  Vol. 3, p.  1-9,  1964.  13 refs.

 Experiments were conducted with rhododendron,  lilac,
poplar, oak, lime, and birch tree leaves to determine
the effect of neutral foundry dust applied for 6 months
on the  production of dry matter.   The following proce-
dure was used:  9 mm diameter samples from both
halves of the leaves were cut out; one half of the leaf  was
then coated  with a mixture of foundry dust and egg white
and the other half was left without contaminant.  The
results showed an obvious decrease in dry matter pro-
duction in 17  forest and decorative species,  with the
exception of rhododendron, as reflected by a difference
in weight.   On the average,  the decrease in  dry matter
in evergreen species amount to 86 percent of the normal
increase and 65 percent in deciduous species.  Also the
total  leaf mass after 6 months  of exposure was reduced.
Thus the negative effect of dust was proved  not only to
reduce the  production of assimilation products but also
the leaf tissue.   The reasons for this inhibition appear
to be of physical nature such as reduction in the light
reception by the  leaf surface, heating of the mesophyll
leaf layer due to heat absorption of the dust  coating and
the effect of the dust on transpiration.

The effect of cement mill dust (containing 36 percent
CaO, 15 percent SiO2) from an electrostatic precipitator
on the susceptibility of sugar beet plants  to disease was
studied in field tests.  Scale  sketches were made of
random  samples of beet plants  on dusted  and non-dust-
ed plots  of ground,  and a leaf destruction rating, ranging
from 0 to 4 was applied.  The data and their statistical
evaluation are tabulated.  The results showed  that  the
incidence of cercospora leaf-spot disease (cercospora
beticola) was  enhanced in the presence of dust. Also the
beet yield from the  dusted areas was lower.  The cause
of the  intensified attack by  the cercospora fungus was
found in the disturbance of  the plant's physiological
equilibrium due to the dusting.   No effect of the dust on
sugar  content was found but undusted leaves has a higher
carotene and crude  protein content.

cessing plant were investigated.  The techniques and
methods used at the plant are  described  indicating the
sources  of emission.  The entire vegetation found in the

damaged by the toxic gases.  Varing degrees of serious
effects and certain evidence of pathological disorders
were observed -  ranging from types of chlorosis to
complete dryness due to a third degree scorching.  The

character and irritation of the bronchial mucosae and of
the main respiratory tracts.  None of the workers  exam-
ined displayed signs of fluorosis. The front teeth of the
workers and part of the premolars display  dark yellow-
green stains. In approximately one-half of the cases the
gingival mucosae showed whitish,  opaque aspects with
some spots  slightly reddened, a moderate tumefaction
and readily bleeding gums.  Caries is  absent in most of
the subjects  with eight years  of exposure,  and extremely
rare in others.  The percentage of caries was substan-
tially lower in children in the vicinity of the plant than
those of the  same age group outside the district.  The
properties of fluorine, its pharmacology,  toxicology,
water toxicity, therapy, and  prophyaxlis are reviewed.

In three standardized fattening sites (pigsties) with
gravitational ventilation,  which accomodated different
numbers of  pigs, the following numbers of measurements
for each parameter were made:  510 oxygen, 514 carbon
dioxide, 516 ammonia, 479 air germ content, 259 temp-
erature, and 258 humidity (relative air humidity).  The
values were  compared  in order to determine the relation-
ship between the separate  factors and to exhibit the cli-
matic factors which must be taken into consideration when
sanitary examination in fattening pig-sties are undertaken.
It was found  that CO2 and G£  levels are inversely related;
CO2 and relative humidity levels are directly related (a
satisfactory  level of below 80% humidity is  associated
with 0.20 Vol.  % COj); CO2 and germ content is directly
related (sanitary) level possible if CO? content is limited
to 0.15).  A  low CO2 content  cannot be taken as valid
proof of sufficient air circulation.  High germ counts and
high dust concentrations are  associated with feeding of
dry non-polletized feed.  Ammonia content is related to
temperature, but not to humidity or CO2 content.

 from lead,  arsenic,  SO2> and fluorine.  Fluorosis has
 gained  considerable importance in the last 30 years and
 today represents the most important disease among the
 smoke  injuries.  Pneumoconiosis very seldom develops
 in animals as a. result of flue ash.   Clinical manifesta-

The effects of air pollution in rural and urban areas are
reviewed.   The effects of pollutants on plants  and animals
and the effects of  radioactivity and pollution due to  chemi-
cal products are considered for rural areas.   In urban
areas the consequences of air contamination on man,
plants,  and materials are considered.   Particular empha-
sis is devoted to air  contamination in Paris,  which is
principally due to emissions from domestic furnaces (3
million combustion units), industrial fumes,  and auto-
mobiles (1.2 million).  These three sources are discuss-
ed in detail, with a tabulation of sources of CO2, SO2,
and fumes produced,  and a discussion on the  influence of
pollution on materials, urban vegetation and man.   A
regulation concerning the fight against air pollution and
odor in France is  presented, including the  establishment
of "protection zones" and strictures on type,  condition
and operation of combustion equipment allowed.

The estimation of damages caused by toxic effluents  is
illustrated in the case of seven agricultural  claimants
against a glass factory emitting fluorine compounds. The
decay of topsoil,  diminished or lack of production of the
plantations,  and damage to cattle through the ingestion of
polluted fodder are basic criteria used in the evaluation.
The nature of damage (including amounts of fluorine
found)  is discussed in detail.   The estimation of indemni-
ties (e.g. value of dead plants) for each of the seven
claimants is outlined.  Technical devices aimed at
eliminating these  emissions  are briefly discussed.

INDUSTRIAL SMOKE DAMAGE FROM FLUORIDES.
[Industrielle Rauchschaden durch Fluor.] Translated

r?(17):575-578, 1962.

The  damage  caused to plants  and animals by air con-
taining fluoride was investigated, and the extent of this
damage and its economic importance evaluated.  Damage
to plants usually takes the form of discoloration of
leaves.   Chemical analyses were performed to determine
the extent of cumulation of fluorine in cereals, truck
crops and fodder plants,  pastures,  fruit trees, garden
and decorative plants, and forest trees.   The green por-
tion of pear leaves gathered contained 8. 5 percent fluor-
ine, and the brownish edge of the leaves, 21.2 mg
percent fluorine,  illustrating that the discoloration was
due  to the effect of fluorine.  Fluoride emissions exert

 quite evident damage on cattle.  The animals  eat con-
 taminated fodder, grass, and hay, and also inhale  quan-
 tities of fluorine.  This explains why these animals
 suffer more in comparison to animals kept constantly in
 stables. The external sympton of such effects is a
 yellow to dark brown discoloration of the incisors,  whose
 enamel sometimes breaks off.  Increased deposition of
 fluorine in the bones sometimes results  in stiff hobbling
 and painful walking.  Chemical analysis  proves that
 animals showing these symptons of fluorine exposure
 have  in their organism too much of this substance.  These
 symptoms were also observed in hogs who were allowed
 to eat in pastures.  Cattle show a  reduction in the forma-
 tion of milk and they conceive poorly as  a result of
 fluoride emissions.

 26  refs.

 Pollution of the air and damage to feed plants, and the
 resulting diseases of humans and  animals, are extremely
 frequent in regions where ore-processing metallurgical
 plants are located.   The fumes being produced during
 roasting and melting of the ore are usually bonded  to
 sulfur and arsenic; consequently the smoke contains
 considerable quantities of SO2 and As2O^.  This smoke
 most affects cattle.  Acute arsenic intoxication becomes
 manifest in the form of vomiting and diarrhea,  caustic
 injuries to the gastric mucosa, and fatty degeneration
 of  the liver.  In chronic cases, increasing cachexia,
 eczema and weakening resembling paralysis are observed.
 The metallic elements in the fly dust, moreover,  can
 lead to harmful indigestion.  During acute lead poison-
 ing, stomach distress is observed, as well as spastic
 movements.  Chronic lead  intoxication leads to a
 malaise combined with abortion, lead colic,  muscular
 pain, epilepsy, and paralysis.  The red  blood  corpuscles
 show a partial basophilic granulation.  Hydrofluoric acid
 fumes from foundries and plants producing artificial
 fertilizers  dissolve the calcium in the bones,  and chronic
 calcium degradation and softening of the bones are the
 consequences.  As a result of an air pollution episode
 in  Luttich,  damage by foundry smoke in  fog caused
 hundreds of persons to fall ill and 63 to  die,  mostly
 within 1 to 2 days.   Hardest hit were asthmatic and
 heart patients,  and persons suffering from bronchitis.
 Copper intoxication was observed  in sheep and cattle as
 a. result of  spraying orchards with lime  and copper.

urea, cholesterol, proteins,  serum albumins and globu-
lins,  and glucose were made.  Autopsy of  these animals

lesions and especially dental lesions.  The limit safe
dose of fluoride that a cow can absorb daily over a long
period of time was investigated.  No delayed growth or
weight gain, or alteration in  the general condition and
hooves  of lactating cows  receiving 2 to 3 mg of fluorine
in the form of natural phosphates, was observed.

A morphological and anatomical study of dwarfed
varieties  of Norway spruce and birch was made.  The
varieties  became established under the chronic influence
of polluted air containing HF from an aluminum plant. A
possible effect of minerals or water in the soil was
excluded.  The  spruce specimen examined was 20, the
Birch,  18 years old.  The trees have a shrub-like,
bushy appearance.   This is due to the  fact that the termi-
nal shoot  of the spruce fades out when it grows beyond a
certain height,  then occasionally the buds from the
lateral  twigs start  to develop.  The shape of the  dwarfed
birch is caused by  elongation of basal  buds.  The size of
the needles and leaves is greatly reduced particularly on
the weather side.   The reduction is due to a decrease in
number as well as  size of the cells.   The number of pith
ray cells  per unit area is increased as we,ll as size of
the cells.  The  number of pith  ray cells per unit area is
increased as compared to normally developed  spruce
trees.   With birch  no different reaction was found.  It
is  open for further investigation if this observation
indicates  a fundamentally different reaction of dwarfed
soft- and  hardwood.

 Data on the influence of dust with different characteristics

 metals are reported.  The following types of dust were
 selected for the corrosion test on carbon steel,  zinc,
 copper and aluminum:  1.  pulverized silica gel,  Z.  ac-

 chemical factory.  No action of dust with high absorb-
 ability for -water vapor and SO^ was found.  In the pre-
 sence  of SO£, the action of the dust can be disregarded.
 A slight aggressive  action may be expected in pure  at-
 mospheres with dusts containing a certain share  of
 leachable components with Cl and 804     Different ab-
 sorbability for -water vapor has no influence on the  ag-
 gressivity of the dust.  With iron, dusts with a small
 content of leachable components form corrosion centers
 in pure atmospheres but these propagate only very  slow-
 ly in the absence of corrosion promoting agents.  By
 analogy,  nonferrous metals  only oxidize.

800 paired samples of indoor and outdoor smoke and SO?
concentrations of 60 Rotterdam homes were studied in an
effort to throw more light on the role that indoor air pol-
lution may play in  epidemiology.  It was found that
smoking increased the amount of smoke found in living
rooms and the data suggest that newer houses tend to
have less SO? in the living rooms than older houses. On
the average living  rooms contained approximately 80 per-
cent of the smoke and 20 percent of the SO2 measured
simultaneously outdoors during 24 hr periods.  The
probability of having more SO2 in the living room than
outdoors is estimated at less than 2 percent of the  days,
but the findings  of  constant high SO2 in one living room
in this small sample may mean that faulty chimneys and
heaters may play a bigger role in air pollution mortality
during fogs than so far has been suspected.  (Authors'

 Parti, London,  4-7 Oct.  1966,  p.  209-210.

 Results are presented of the investigation of the carbon
 monoxide concentration measured in city streets at
 different altitudes above  street-level simultaneously.
 The influence of traffic-density, wind velocity and wind
 direction on the carbon monoxide concentration in  dif-
 ferent levels is discussed.  The results show a diurnal
 trend of CO concentration in all levels above the street,
 the amplitude of which is determined by the rate of
 emission of automobile-exhaust gases and the "wind-
 distribution.  The  evaluation of the effect of wind on the
 CO concentration reveals a  great difference whether the
 measurement of carbon monoxide is carried out on the

 PROVISIONAL METHODOLOGY FOR COMPUTING AT-
 MOSPHERIC DISPERSION OF WASTE ASHES AND
 SULFUROUS GASES FROM POWER STATION SMOKE-

 Teploenergetika, No. 7, p. 89-92, July 1964. C.I.T.E.P.A.
 Documentary Information Report No. 20, CI 208.

 The method proposed  is  based  on theoretical and
experimental  work carried out in the vicinity of a large
thermal power station. It is valid for the calculation of
dispersion of pollutants, determination of the necessary
height of smokestacks, and for attaining normalized
values of ground-level concentration of such pollutants.
The report explains how to apply the formula defining
maximum concentration and how to select the various
factors involved.  A graph is proposed which gives,  in
terms of maximum concentration at a given distance, the
value of the concentration of pollutants at  other points,
and, finally, a method is  described  for calculating the
minimum height of smokestacks  compatible with the
authorized limits of concentration of waste products in
the atmosphere.  An example is  given of the practical
application of this method in calculating the maximum
concentration of noxious impurities  at ground level.

COMPARISON OF THE CONCENTRATION OF SUSPEND-

ANTS BETWEEN INDOOR AIR AND OUTDOOR AIR IN
URBAN AREA.  Translated from Japanese. RodoKogaku,
41_(10):493-500,  1965.  18 refs.

The concentration of  suspended particulate matter and
gaseous pollutants of indoor and outdoor air in Tokyo
was determined at several locations including factories,
business machine rooms  and offices.  The concentration
of suspended particulate matters -was determined by Roken
Type long term recording impactor and gas analysis for
SO2, NO~ and HCHO  of indoor and outdoor air was
carried out at the same time.  The electromicrographs
revealed that most of the particulate matter in the urban
area -was microfine,  seeming to be carbon particles and
some mist particles.  The concentration of suspended
particulate matter of the  outdoor air in the urban area
ranged from 0. 05 to  0. 5 mg./m and that of the indoor
air in air conditioned rooms ranged from 0. 01 to 0. 3
mg/m3.  The attenuation efficiency of an air  filter with
electrostatic precipitator for suspended particulate
matter was high.  The concentration of SO2 of the in-
door air was lower than that of outdoor air, but the dif-
ferences were not marked in cases of NO2 and HCHO.

AIR-HYGIENIC MEASUREMENTS OF THE RELATION-

The relations between SO2-immission,  number of nuclei,
number of germs,  as well as the meteorological factors
of air temperature, wind velocity and rainfall were ob-
served at two measuring points  (a dwelling area and an
industrial area) of a big city for one year's  time.  The
number of nuclei changed in the same direction as  the
SOz-immission.  This  was due to their same  sources of
origin.  The number of nuclei changed counter-directional-
ly towards the temperature.  This was due to a secondary

 influence exerted by the heating processes in winter, as
 well as by the improved exchange conditions of atmos-
 pheric air existing in  summer.  The SOz-concentrations
 were directly dependent on the rainfall conditions; there
 exist secondary relationships  with air temperature.  Re-
 lations between the number of germs  and the SC>2-im-
 mission however, existed only at one measuring point
 and even there only under certain bacteriological ex-
 perimental conditions.  All further comparisons, parti-
 cularly those concerning the number of germs and the
 number  of nuclei, air temperature, wind velocity and
 rainfall  revealed  that  the measuring values obtained
 •were completely independent of one another. The number
 of germs is of no practical importance as an air-hygienic
 indicator for characterizing the pollution of the  atmos-

 The values for carbon monoxide are given in a  report by
 the Paris Municipal Laboratory which has  followed the
 carbon monoxide  values determined in the  Paris streets
 since 1956 as indicative of the air  pollution from automo-
 biles. A statistical examination was  made of the 15, 187
 samples  taken at  317  sampling stations.  Two percent or
 312 samples had a carbon monoxide content of 100-200
 ppm, 27 or  0. 2 percent were from 200-300 ppm, and 11
 were above  300 ppm.  The average values for carbonmon-
 oxidein  1965 was  24. 3 ppm compared to 23 . 9 ppm in 1 964,
 and 31.1 ppm in 1963.  There  are numerous tables show-
 ing the carbon monoxide at various sampling stations and
 at  various underground passages.   Studies are also  re-
 ported of the carbon monoxide in the blood among three
 groups:   persons -who feared they had been affected by
 carbon monoxide, workers who were exposed to carbon
 monoxide, and drivers involved in an accident who had
 blood taken to determine alcoholic content. An appreci-
 able  number of persons in each group had  CO levels in
 the blood  which were  a matter of concern.  While the
 slight increase  in the 1965 figures is not significant,
 there is no doubt that the number of cars will continue  to
 increase as -will the problem.

 Assuming a. sedimentation and diffusion equilibrium for
 natural aerosols  in the lower  atmosphere,  theory pre-
 dicts  an  upper limit of the particle  size of 20 to 30 |i. For
 experimental verification, a special particle detector
was designed which is  capable of detecting one particle
per cubic meter.  It consists  of a rotating propeller
whose blade tips are lined by adhesive strips made of
 silicon oil.  The  apparatus and its calibration are
described in detail. Measurements in Mainz,  theTaunus,
the Black Forest (1480 m),  on Helgoland, and on the
Jungfraujock in Switzerland (3570 m) revealed no upper
limit of the particle size up to ISOji.  Furthermore, the
results were remarkably uniform and showed no depend-
ence on locality (and thus local emission sources),
altitude, or elevation.  The distribution of the larger
particles is a. smooth continuation of the distribution of
the sizes between 0. 1 and 10 |J..

Results of CO-measurements made in the urban areas
of Hamburg and Kiel, West Germany, are reported.
After a brief discussion of the constituents of automobile
exhausts and of previous  CO-measurements,  results of
CO-measurements performed with the Draeger gas
detector model 9/31  are presented in six tables. Of
35 measurements made in each city  from a moving
passenger car  during rush hours,  eight values were
above 0. 01 percent (maximum allowable concentration)
in Hamburg and two  in Kiel.   Since both cities have
favorable climatic conditions, it must be concluded that
higher concentrations may occur in other communities.
Improving the flow of traffic and avoiding smoking  while
driving are recommended.

CHANGE OF DUST CONCENTRATION .INDOORS.   Trans-
lated from Japanese.  Japan Air Cleaning Assoc.  (Tokyo),
3j4):32-35,  1965.  5 refs.

Factors which affect the change of dust concentration
indoors are the concentration of outdoor dust, dust
generation due to combustion or air flow,  and sedimen-
tation.  The relation between dust concentration indoors
and  out is graphed for periods during which the air
conditioner was on and off.  Tests were performed for
dust sedimentation and also when CO2 and dusts were
generated in the same room.  It was observed that the
smaller the particle  size, the smaller the sedimentation
ratio,  the ratio being the greatest at the moment dust
generation stopped.   The ratio was also larger in rooms
with ventilation than  without.  The theory for quantita-
tive  investigation is given illustrating that the concentra-
tion  at time t is expressed:  Cr (t)=Cs(t)+Cf(t) + Co(t),
where Cs accounts for indoor dust generation, Cf for
outdoor dust generation, and Co is the contribution to
dust at t=0.  The assumption made here is that the
quantity of air entering  and leaving the room  is the same.
Measurements of the amount of air ventilated by dust is
not easy to determine; sedimentation rate  determination
is likewise difficult.

Since the fall of 1964, 223 dust sampling locations have
been set up in Hamburg, which are equipped with Berger-
hoff jars.   Six locations have more than one unit.  Dust
precipitation is measured in mg x m   x day -1   The
periods of measurement and some results  of the statisti-
cal analysis  of the precision of the measurements are
tabulated.  Generally,  short periods yielded higher
average values and large variations.  Air pollution by
dust is described by the "characteristic concentration
parameter" (Ij,  !£>,  as defined in the "Technical direc-
tives  for clean air maintenance".  A map of Hamburg is
reproduced in which areas of specific maximum Ij
values are indicated.  These  results are discussed and
explained by  relating them to dust-emitting sources. A
detailed statistical analysis also supports the view that
there is a strong relationship between dust precipitation
and atmospheric precipitation and that there is good
correlation between dust precipitation and  wind together
with dry ground.   These preliminary results already
indicate that  strong dust sources must be limited and
that watering the streets during summer is essential.

AIR POLLUTION CAUSED BY RESIDENTIAL AND
INDUSTRIAL HEATING IN THE CITY OF ZURICH.
[Die Luftverunreinigung durch hausliche und industrlelle
Heizungen in der Stadt Zurich. ] Translated from German.
Neue Zurcher Zeitung, "Technology" Supplement, Nov.
18, 1964, p. 3-10.   9 refs.

The systematic testing of the air in Zurich is discussed.
Sulphur dioxide measurements were made from May 1962
to 1964 at 28 measuring points, distributed over the
entire Zurich area.   Liesegang's  method was used in
taking the measurements.  Over 1, 500 samples have
been collected.  During the months May  to September
the sulphur  content of the city air averaged one  to two
milligrams  per one hundred  hours of exposure time.
For the industrial area the sulphur content in the
summer is considerably higher than in the other areas.
From December  through March the villa quarter had a
peak at  11.5 mg of sulphur.   The  residential quarter
and the densely populated residential area  measure-
ments were similar.   The mixed residential and indust-
rial area produces a  somewhat higher level of sulphur
content.  The air in Zurich has not reached an intoler-
able limit of pollution.  Seven hundred oil heating instal-
lations, distributed over the entire city area, were
tested.  All solid and all unburned liquid parts of the
flue gas were precipitated onto the filter paper and
analyzed.  The individual measurements were evaluated
according to the Bacharach scale.  For each installation
a check sheet was prepared which made very rapid and
simple evaluation possible.  A few of the oil  burners
and heating  pots were manufactured prior to  1945.   No
very great differences in their way of functioning were
observed.  Those manufactured between 1945 and 1955
plainly had many more defects than the two next  cate-
gories, from 1955 to I960 and from  1961 to 1964. In
a table,  five of the most heavily represented types of
pots and burners  are shown and compared to the soot
figures.  Instructions for the installation of and  for
owners' operation of oil burning heating equipment are

AN ASPIRATOR ATTACHMENT FOR  24-HOUR AIR
SAMPLING.  Translated from Russian.  Gigiyena i
Sanitariya,  No. 7,  p.  60-61,  July 1965.

An attachment  for an aspirator to facilitate unattended
sampling for air pollution is described.  The aim was
to provide intermittent operation; 2nd hour on,  2nd hour
off to allow  the aspirator to cool completely before
repeating the cycle.  This attachment allows the aspira-
tor to automatically turn on and off to maintain normal
operation.   This attachment can also be fitted onto other
pneumatic pumps or aspirators of any type.   The attach-
ment consists  of a starter,  three  relays, four diodes
and a clock.  The attachment  works on a current recti-
fied by a diode bridge.  An alarm clock is used as  a time
gauge to the hour hand of which a  small cam of organic
glass -with 3x6  millimeter dimensions is attached.   This
cam, completing one revolution per hour along with the
hour hand, breaks small contacts built in under the
clock cover.  With breaking of these contacts the con-
tacts the condenser becomes  charged.  As soon as the
contacts are completely closed, impulse relay  drops,
and its normally closed contacts close,  while the
normally open  contacts break.  At this time the con-
denser discharges onto a switch-on relay as o. result of
•which the starter is switched  on through the normally
open contacts of the starter relay.  Thus, the normally
closed contact  breaks, and the normally open one closes
and the aspirator is switched  on.  With the next revolu-
tion of the cam the  condenser discharges onto a switch-
off relay, the circuit of the starter coil is broken,  and
the aspirator switches off.  Then  the described cycle
repeats itself in the same sequence.

CO level "was  sampled in air taken from 8 areas of dense
traffic during the period 1961-1964.  Levels found ranged
from ff to 45 ppm,  with occasional peaks to  90 ppm.
These levels were about the same each year, in contrast
to the sharp increase in the number of automobiles dur-
ing that  period.  No conclusions are drawn from this
observation, but the ambient air  concentration of other
exhaust  gas components is pointed out as also signifi-
cant.  Averages  are given for ammonia, SOz, NO2, and
aldehyde.  In order to clarify the  possibility of eventual
harm from lead additives in gasoline, urine samples from
all traffic policemen were examined in 1965.  There was
no evidence of lead accumulation  in any of the samples.

 The presence of airborne acid particles was monitored
 and the particles sized, using thymol blue-gelatin film.
 In Tokyo and Osaka air,  acid particles were detected
 frequently -with  most around a micron in size.  In fog,
 acid droplets as large as 30 H- "were detected.   No acid
 particles were detected in Asahikawa.   Laboratory
 experiments on the adsorption and oxidation of SO£ on
 the particle  surfaces indicate that manganese  salts,
 active carbon, and coal soot  can lead to the formation
 of acid particles.   SO2 appears to react with CaCO3 or
 iron oxide to form sulfate. Some of the particles
 suspended in Tokyo air were capable of producing acid
 particles, whereas airborne particles  in Asahikawa
 had no such  activity.  (Author's  abstract, modified)

 Measurements were conducted from October 1965 to
 September 1966 of sulphurous anhydride  (SO2> and
 carbon monoxide.  The analyses were completed by a
 systematic study of various sensitive biological tests
 in the presence of polluted air.   SO^ was measured by
 two methods; gravimetric measurement and measure-
 ment by an automatic recording apparatus which meas-
 ures  electrical conductivity.  Carbon monoxide was
 measured with the  Uras  apparatus,  which measures
 infrared ray absorption.  Biological tests were run by
 making measurements of pine needles and lentil seeds.
Dust was  measured with membrane filters, using gravi-
metric analysis.  Germs were measured with the same
 apparatus used for dust,  then seeded on solid  culture
medium.  The  titer  of absorbed SO2 is much higher in
winter than in summer.   In summer, the diurnal SO2
titer is higher than the nocturnal titer.  The CO titer
varies during the day,  the diurnal titer being almost
double that of the nocturnal titer.  No results are given
for winter measurements.  Those for summer  are  dia-
grammed.  It is concluded that foreign gases are pre-
sent in air currents from aeration openings and act on
the growth and metabolism of the nearby pine needles
and lentil plants.  The dust titer was found to be  rela-
tively low in the city.  The increase in total germ titer
was  in direct ratio with the occupation of work  locations
and of streets.  A mobile laboratory is described.

and evening rush hours; an infrared absorption device
measured CO levels.  About 90 percent of the samples
exhibited 25 ppm CO or less, with the mean value at
14. 5 ppm.   These figures can be compared to the con-

ments of the CO level and of wind distribution in dif-
ferent levels above the street  were performed.   The
apparatuses used are described.  Evaluation  of the data
•was carried out with respect to traffic density,  "wind
velocity, and  wind direction.  The results show a diur-
nal trend in all levels, the amplitude  of which is deter-
mined by the rate of production of automotive exhausts
and by  the  wind distribution.   There is  an empirical  dif-
ference, which is described graphically,  between meas-
urements of CO on the weather or on the lee side of  the
street.  Based on these results, a model of air circu-
lation in the streets and of street ventilation can be de-
duced.

 PHYSICAL PRINCIPLES FOR DEVELOPING A METHOD

 A Russian study is translated which examines  the vari-
 ous physical principles involved in establishing a tenta-
 tive method for calculating the dispersion of pollutants
 in the atmosphere.   Starting with the known turbulence
 theory and applying modern methods for solving differ-
 ential equations with the  aid of electronic computers,
 the study considers: the vertical component of the tur-
 bulence  exchange coefficient and how it varies with
 height; the conditions of temperature stratification in
 the atmosphere; and the sedimentation rate of the im-
 purities--both gaseous and solid.   The  various para-
 meters of pollutant discharge are  examined:  height of
 smokestack, initial velocity of combustion gases, dia-
 meter of the smokestack opening,  volume of gas dis-
 charged as  a function of time, etc.  Based on the above,
 a method is then developed whereby it is  possible to
compute —for a wind velocity considered dangerous and
under average meteorological conditions —the maximum
concentration of light impurities,  heavy impurities, and
impurities discharged by several  smokestacks of the
same height.  Corrections are proposed for the special
cases of temperature inversion or irregular terrain.
The distance at which  the maximum calculated concen-
tration is  obtained is found proportional to the height of
the smokestack.  The  theoretical  calculations agree
with actual measurements.

ERRORS  OF DETERMINATION OF THE MEAN DUST

Previously,  it had been assumed that the coefficient K
of the  change of concentration remains constant during
a specific technological process and under specific pro-
duction conditions.  This assumption led to the assumption
                                                                                                                 S3

  that the standard deviation remains constant for a loga-
  rithmically-normal distribution; these assumptions would
  significantly simplify calculations and diminish the error
  of the mean value determination as a function of single
  measurements.  This hypothesis dealing with the loga-
  rithmically-normal distribution was to be applied to both
  gaseous and  atmospheric pollutions.  By checking with
  a serial determination of the SC>2 levels in the air, the
  hypothesis could only be proved to about 13 percent, and
  thus cannot be accepted.

 OZONE IN ATMOSPHERIC LAYERS NEAR THE GROUND.
 [L'ozone dans les couches voisines du sol. ] Translated
 from French.  Geofis.  Meteorol. (Genoa),  9.(l-2):l-4,
 April 1961.  10 refs.

 Many local factors can affect measurements of ground-
 level ozone concentrations and distort their geophysical
 or meteorological significance.  Some  of these are:
 winds, site of the sample intake (which should be quite
 high),  ozone destruction by large or small  concentra-
 tions of dwellings,  and automobile exhaust gases.  Nitro-
 gen pexoxide is  the reason for the destruction and for-
 mation of harmful ozone by automobile exhaust pollution.
 A comparison is made between the effects of exhaust

discussed briefly "with the help of tables and illustrations
and wind direction compasses.  Such measurement re-

The effect  of this initial loading (initial stress) on the
height of the chimney, which is necessary for reasons
of air hygiene, is presented here with the help of  two
examples.  In conclusion, possibilities are mentioned
which might permit the use of lower chimney heights
without neglecting clean-air requirements.

Concentrations of  dust and bacteria in concrete apart-
ments and Japanese wooden houses  during  the summer
are reported.  The results are  compared with previous
measurements  made during the winter.   The relation-
ship of these measurements  by  time of day as well as
daily activities and outdoor concentrations  are reported.
The  outside dust density in the center of cities shows
regular variations.  This density is quite high, particu-
larly during winter, and occurs indoors almost to the
same extent.  There are sometimes decreased densities
because of doors or curtains  or time lags,  but the direct
effects of outside air on the atmosphere indoors are
clearly present.  The generation  of dust through daily
activities is of comparatively short duration  and is not
directly reflected  in the daily variations in density.   On
the other  hand,  the number of airborne  bacteria does
not show the same regular fluctuations as dust density.
It is low from late night to early morning,  and high
during waking hours.  It is thought that  the fluctuations
in the outside air are not directly reflected in an in-
crease in the bacteria count indoors.

The climatic conditions  of classrooms in six schools

are described. The following parameters were measured,
both indoors and outdoors:  dust, microorganisms,  tem-
perature, humidity, air velocity, and air  cooling capaci-
ty.   Average numerical  values of total bacterial load and
of staphylococcus are tabulated.  It appears from the re-
sults that the only decidely negative  element in the  class-
rooms investigated was  the high bacteria load found
during lesson hours.   Dust content of the classrooms was
invariably  lower than that of outside air - with no signi-
ficant differences between inhabited  and empty class-
rooms.  The average dust particle diameter,  however,
was  0. 5 n in the empty rooms,  as against a considerable
disparity in form and dimension of dust particles collect-

AIR POLLUTION IN OSAKA CITY AND INSIDE BUILD-

6p.  3 refs.

Measurements were made of the outdoor and indoor dust
concentrations in the air and its  diurnal and seasonal
variations in the city of Osaka.   The shifting patterns of
outdoor dust and dirt density during a 24-hour day, with
varying wind velocity, and at various heights of a build-
ing, are shown graphically and discussed.  SO2 concen-
trations were measured also.  The Roken type instru-
ment for counting dust particles  was found to be very
laborious for high dust concentrations.  Recent develop-
ments  indicate a preference for dust measurements by
weight rather than by particle count.  The usefulness
and advantages of different analytical instruments  are
discussed.   The role of electrical dust collectors is
evaluated for eliminating indoor air pollution.  These
devices,  unlike air filters, capture particles less  than
one micron in size,  but they are expensive.  It is em-
phasized that a reduction of outdoor pollution reduces the
level of indoor pollution.

Measurements of the dust concentration with "Eiken"
dust meters  inside rooms of a residence, a hospital,
and a school in Japan "were made with simultaneous  out-
door concentration measurements .  The  results plotted
as seasonal and daily dust concentration  changes show-
ed that  peaks occurred at 10 a.m.  and minima at 1-2
p.m.  This is attributed to smoke and  dust generated by
heating.  The dust density reached a maximum of 2346
particles  per cc in December and a minimum of 752
particles  per cc in June.   The dust  concentration inside
the building is directly proportional to that on the out-
side; this fact holds true  not only within relatively small
rooms,  but also within hospitals and schools.  During
the late morning a sudden and precipitous reduction of
dust density  from the forenoon peak is  noted.  The dra-
matic wintertime increase in dust density is  completely
consistent with measured data on soot  precipitation, pre-
sumably due to heating.

used involved exposing Petri dishes containing a thin
layer of beer wort,  gelatin or apple extract or sweat-
spoons with gelatin in the  places to be studied for 15
minutes.  The  organisms  found can most naturally be
divided into three groups:  bacteria, yeast-like-germi-
nating fungi, and fungi with mycelia.  Mold fungi oc-
cured far more frequently than bacteria  and yeast-like-
germinating fungi.  Considerably fewer species were
found inside than outside;  8. 7 and 58. 3,  respectively,
on the average  per analysis,  corresponding to about
13, 000 inside and 87, 000 germs outside per square
foot per day.  Brief comments are made concerning
some of the species  found. The results are compared

                                        LEGAL AND ADMINISTRATIVE ASPECTS
A Polish regulation requires establishments  emitting
pollutants to submit reports containing the following in-
formation:  (1) description of source, (2) operational
time, (3) average amount of waste, their temperature
and rate of discharge, (4) type of pollutant, (5) charac-
teristics of  control equipment, and (6) height and dia-
meter of individual outlets of pollutants.  The organi-
zation handling matters of air protection determines the
amount  of pollutants an establishment can discharge.

A regulation in Poland  stipulates that organizations
handling matters  of air protection and the state health
inspectorate should exchange opinions regarding plans
of economic utilization of space and preliminary pro-
jects of construction or reconstruction.  They also
should inform each other on the following subjects:  (1)
annual plans of measuring  pollutants,  control measure-
ments,  and plans for  the control of establishments,  (2)
programs and results  of studies  and scientific research,
and (3) results  of inspections and measurements.

DECREE ON PROTECTION AGAINST AIR POLLUTION.
Translated from Polish.  Monitor Polski (Warsaw), No.
32, p. 341-345, June 15, 1967.

The width of protection zones surrounding industrial
emission sources in Poland was established.  Manu-
facturing establishments which emit substances causing
air pollution are classified - depending on the type of
their  production - in one of five categories for which
the width of the protective zone is as follows:  Class I-
1000 m, Class II -  500 m, Class in  300 m,  Class IV
100 m, and Class V -  50 m.  The width of the protective
zone is measured in terms of a straight line from the
source of pollution. The classifications of 280 types of
establishments which emit substances and pollute the
air are listed according to each category.

TRAFFIC IMPROVEMENT AND AIR POLLUTION.
[Verkehrssanierung und Lufthygiene.]  Translated from
German.  Z. Praeventivmed.  (Zurich),  ll(2):220-225.
March-April 1966.

Since automotive emissions are  lowest at speeds of
about 60 km/hr, an increase in speed which increases
the traffic capacity of city streets can reduce air
                                                            pollution.  More traffic does not necessarily produce
                                                            more pollution.  Therefore,  all measures for increasing
                                                            the capacity of city streets to expedite the existing traffic
                                                            are also advantageous from the viewpoint of air pollution.
                                                            Traffic  control measures such as  construction of under-
                                                            passes and bypassing of through traffic are discussed.
                                                            It is  pointed out that Los Angeles is the only  city with
                                                            air pollution caused primarily by automotive exhausts.
                                                            After removing industrial emission sources from  Pitts-

                                                            Modern city planning should have as its objective the
                                                            abatement of noise and air pollution.  The modern
                                                            street system should have no intersections, only curves
                                                            for direction changes; noise protection walls should sur-

                                                            should be eliminated.  Specific examples in German city

 This directive interprets the provisions in Decree No.
 63-963, of September 1963, and relates them with the
 1917 statute, with amendments, and with the Law of
 August 1961, which covers all establishments deemed
 dangerous, unhealthy,  or inconvenient. The 1917 Law
 gives the Prefects the power to institute criminal pro-
 ceedings against offenders.  The difference between the
 1917 Law and the Decree of 1963 appears to be the dif-
 ference between a rigid classification of air pollution
 sources, and the prescription of a grade series of re-
 gulations to  be applied, where applicable, throughout
 the country.  Title I, containing minimal regulations to
 be applied throughout the country, is to be  used in the
 effort to require complete  combustion  in heating ap-
 paratuses.  Other Articles in the new Decree are inter-
 preted. A course by the National School of Public Health
 is announced whereby departmental or communal health
 inspectors can acquire a working knowledge of heating
 techniques and checking and control  methods.

 MONITORING OF SO2 POLLUTION IN THE INGOLSTADT
 REFINING  CENTER.  [Uberwachung der Luftverunreini-

 24(10): 390-395, Oct. 1964.  8  refs.

 About I960, a petroleum refining center was established
 at Ingolstadt.  Based on meteorological studies  of the
 area, it was shown that Ingolstadt was not an ideal area
 to locate  such a refinery center:  Ingolstadt has more
 frequent periods of low wind velocity than other German
 communities.   Thus, SO£ levels can rise  to dangerous
 levels. Monitoring stations and a mobile  monitoring
 unit are described. Meteorological readings obtained
 are graphed.  These daily average SO2 readings are
 used to activate the official five-stage  "SOz Alarm Plan",
 whereby the refineries can be required to reduce pro-
 duction, and thus  reduce emission of SOzi  or even to
 stop work.  For example, a daily median  value  for all
 monitoring stations of 0.5-0,6 mg/m  , or half-hour
 SO2 excess above 7.5 mg/m^, (Alarm Level II) could
 require a 20 percent reduction in plant emission.  With
 this plan in effect, the plants are not required to use
 low-sulfur fuel all the time.

 After a  historical review of air pollution and its control
 in England, the Alkali Works Regulation Act of 1906 and
 the Clean Air Act of  1956 are described.  In the Act of
 1906, 25 types of plants which emit noxious gases were
 defined and registration and annual inspections of such
 plants were required. Penalties could be incurred for
 emission or non-cooperation.  The Act  of 1956 deals
 with smoke abatement for  smokes  derived from com-
 bustion only, leaving the Alkali Act of 1906 and Public
Law 1936 still  in effect. Emission of dark smoke is
prohibited and fines can be incurred for operation of
heating installations with the emission of dark smoke,
or for emission of smoke  in control areas or smokeless
zones.  Private organizations such as the National Soci-
ety for  Clean Air,  have also been active since 1899.
According to civil  law, action for damages can be re-
quested in case of  personal damage or damage to pro-
perty.

CONTROL, [italien:  Probleme der Luftverunreinigung

Luft Betrieb (Mainz), _9(2): 118-119,  Feb. 1965.  ISrefs.

Due to its favorable climate and geography,  Italy has
had no urgent air pollution problems in the past.  Only
as recently as 15-20 years ago, with the advent of in-
dustrial centers  and the increase in automobiles, has
Italy paid any attention to air pollution.  There is as yet
no special law regulating the problem.  Relevant pro-
visions of the Civil Code, the Penal Code, the Public
Health Law, and the Town Planning  Law are discussed.
Unfortunately the Road Traffic  Act  of 1949 does not
contain any provisions for vehicular exhausts, although
the regulation of excessive traffic noise is included.
Instead, local authorities have  enacted public health
ordinances  to protect the health of the population, for
example, Milan in 1952,  Genoa in 1955, Turin in 1962,
and Bologna in 1957.  These  local laws deal  mainly
with air pollution caused by heating installations.

Ireland's island location and climate do not favor air pol-
lution.  There are thus very few laws  which are concern-
ed with air pollution.  The Civil Law provides the usual
legal safeguards. The English Penal Law (which is still
valid) and  the Criminal Justice Act together provide for
action following damage to persons, plants, animals,
and objects,  but  in the absence of any  special penal re-
gulations,  claims of injury or damage  from air pollution
are not admissible.  Instead, the English Alkali Act of
1906  is in  force, specifying 21  types of industries whose
emissions  should be controlled.  The Local Government
Act of 1962 and the Road Traffic Act of 1961 provide for
the establishment of air pollution regulations,  and  for
the monitoring of air pollution, as well as prohibit the
excessive  emission of fumes or visible exhausts from
vehicles.  Town  Planning Legislation does not contain
any special regulations on the prevention of air pollution.

The  Netherlands have had laws for  some time which deal
with the prevention or control of air pollution, but no
comprehensive "clean air" law. Relevant portions  of
the Civil Law, the Penal Law,  the Nuisance Law of
1952, and the several regulations and ordinances  are
discussed.  There are no mandatory regulations limit-
ing air pollution.  Generally, the Nuisance Law meets
the needs of the communities.  Six  private organizations

The Air Pollution Control Act of June 2, 1962 is pre-
sented.  This act was enacted for the purpose of con-
trolling the disposition of soot and smoke created by
plants and workshops  so as to prevent danger to public
health due to pollution,  to insure the maintenance of
healthy living conditions and the steady development of
industry,  and for the purpose  of establishing systems
for the conciliation of disputes concerning  air pollution.
Penalities are also listed. The  cabinet order fixing the
enforcement date for the Air Pollution Control Act
(Order No. 435 on 30  November 1962) is also provided,
as well as the  cabinet order on the enforcement of the
Air Pollution Control  Act (Order No. 438 on 1 December
1962).  Ministerial Rules on the enforcement of the Air
Pollution Control Act  are listed, including format of
the notifications  to be used.  Other statues related to
air pollution are parts of the Mineral Mines Safety Act
of 1949, the Act  on Temporary Measures to Control
Electrical Industry of 1952, the  Gas Industry Act of

and the Ruhr area, Germany, New York City, and Los
Angeles County are discussed in detail, tabulated and
compared.  The differences in predominant types of
pollution - e.g. photooxidation in Los Angeles, SO2,
soot,  etc.  in New York, and SO2 in the Ruhr  area - are
noted, -with a detailed explanation of the complexities of
Los Angeles smog  and of the various alarm stages used.
The possibility and desirability of introducing an alarm
system in the Netherlands is discussed. With increased
motorization,  the chance for damage to horticultural
districts is increasing,  and an alarm system, resulting
in the  limitation of traffic under unfavorable  conditions,
may be required.

COOPERATION IN THE FIELD OF DESULFURIZATION
OF COMBUSTION GASES.  Translated from Polish.
Letter and 7 attachments to American Embassy,  Warsaw,
Dec.  13,  1967.

Six topics of planned research projects to be conducted
in Poland in cooperation with the United States in the
field of desulfurization of combustion gases are outlined.
For each topic, scope of investigation, participating in-
stitutions, anticipated results,  technical-economic sub-
stantiation of the scope  of research,  state of research,
description of research methodology and plans, and
proposals to the United  States are listed.  The concepts
outlined include "SO2 sorption with metal oxides",  com-
bining stack gases with  gaseous ammonia", and "the
use of dolomite to protect boiler heating surfaces",
among others.

VDI Richtlinien 2306, 5p. , March 1966.

The VDI Guide Lines for Maintenance of Purity of the
Air fall into the following groups:  1.  Maximum Im-
mission Concentrations (MIK); 2.  Dissemination of non-
atmospheric substances in the atmosphere; 3.  Restric-
tion of the discharge of such substances; 4.  Analyses
and methods of measurement.  For the purpose of main-
tenance of air purity, MIK values are needed for numer-
ous organic compounds.  They can be used as reference
values for the dimensioning of relevant installations and
for evaluation of measurement data in the immediate
vicinity of sources of contamination.  If the MIK  value
for a  substance is unknown it is  recommended that if
there are no known reasons to the contrary about 1/20
of the maximum allowable concentration value be taken
as a start.  Technical societies  recommending person-
nel to serve on the VDI Commission on Maintenance of
Purity of the Air are listed.  Neither the MIK or MAK
values are listed.

Section B, No. 2, 8p., April 3, 1965.

Tolerable limits are set for sulfur dioxide as an air pol-
lutant under normal conditions.  The  limits were chosen
such that as long as they are observed, even sensitive
individuals and species will not suffer any impairment
of their health.  The recommended limits are meant to
serve as a basis for the planning and  constructing of
equipment which will emit sulfur dioxide.  These limits
are also meant for evaluating existing conditions,  and
for judging damage.  These directives are the guiding
principles of the Swiss Commission for Air Hygiene for
owners and users of installations which emit sulfur di-
oxide and for  supervisory and regulatory public agencies.
A brief summary is given of the effects of sulfur dioxide
on man, animals, and plants.  The recommended limits
of sulfur dioxide content of the atmosphere are given as
limits for dayaverages and limits for  half-hour averages.

PERMISSIBLE  CONCENTRATION OF AIR POLLUTION.
Translated from Polish.  Dziennik Ustaw (Warsaw), No.

Maximum allowable concentrations of 803, HzSO4, NOX,
H^S,  CO, gasoline, dust, and CSj in "special protection
areas" and "protected areas" in Poland are outlined.
Special protection areas include areas of health resorts
and health protection areas, national parks,  and reser-
vations of natural  resources.  Protected areas include
other terrains of the land, with the exception of land oc-
cupied by manufacturing establishments or other sources
of pollution and protective zone areas.  Exceptions for a
specified period can be granted in the following cases:
(1) Difficulties involved in the installation of air purifi-
cation facilities  in the manufacturing establishments due
to exceptionally  high investment costs, lack of opportu-
nities to find a producer of such equipment or appropriate
technical methods;  (2) Excessive agglomeration of manu-
facturing establishments in a. given area, which causes
air pollution  in excess of the permissible concentration
in spite of the utilization of appropriate purification fa-
cilities;  (3) When a new manufacturing  establishment
will exceed the maximum permissible concentration of
air pollution  in spite of the fact that the most adequate
control  equipment has been installed.

SWEDISH MEDICAL AIR QUALITY GUIDES.  [Medici-

Translated from Swedish.  Nord. Hyg. Tidsk.  (Copen-
hagen), Vol. 46, p. 1-32,  1965.  46 refs.

The air pollution situation in Sweden,  including the
medical effects of specific pollutants, is discussed and
compared with published data from other countries.
After a discussion of threshold values and exposure
levels, medical factors such as the carcinogenic,  muta-
genic, toxic,  and annoyance effects of specific  pollutants
on the body are examined - with a special section on
respiratory effects.  In an effort to set air quality guide-
lines  despite the dearth of data from Swedish studies,
the following maximal permissible values were recom-
mended: Sulfur dioxide  25 pphm (2 hour sample);  5
pphm (30 day sample).  Carbon monoxide - to be kept
as low as possible and  under no circumstances higher
than 30 ppm(8 hour sample) and 120ppm(l hour sample).
Soot   an increase should be avoided (no recommenda-
tions  made for nuisance effects). No quantitative  guide-
lines  are presented for metals, carcinogenic and muta-
genic substances, and  pollutants  causing sanitary  nui-
sances.  Further data  collection is urged.

 FRESH AIR QUALITY STANDARDS.  [Kwaliteitsnormen
 Buitenlucht.]  Translated from Dutch. T. Soc. Geneesk. ,
 No. 46, p. 166-176, 1968.   58 refs.

 Fresh  air quality standards in different nations  are re-
 viewed.  Considerable differences exist because the
 hazards of air pollution are assessed differently.  How-
 ever, the differences in clean air specifications appear
 to disappear as the maximum  permissible impurity con-
 centrations become gradually  lower.  The Committee
 for Soil, Water and Air  in Rotterdam developed stand-
 ards which have no legal significance but  help govern-
 ment and industry to establish clean air policies.  These
 standards are tabulated for  chlorine, hydrogen fluoride,
 carbon monoxide,  ozone, nitrogen dioxide,  sulfur di-
 oxide,  hydrogen sulfide  and sulfuric acid  with compara-
 ble standards  shown for West  Germany, Russia, and
 the United States.  The permissible SO;> concentration
 in California is higher than  in Europe.  This is  due to
 the fact that SO^ plays a minor role in summer  fog for-
 mation.  In Europe,  however, fog occurs  in the winter
 and is accompanied by high  SO£ and  smoke concentra-
 tions.  Another notable difference in air quality stand-
 ards is that the Russians have unrealistically high
 standards for clean air while in Western  Europe air
 is  considered as a raw material which should be left  in
 a reasonably good condition for the next consumer. Air
 quality directives, being used for the city of Rotterdam,
 and air pollution alarm systems used for  Los Angeles
 and proposed for New York, are discussed.

 AIR POLLUTION.  I. AIR QUALITY GUIDES, SURVEY
 TECHNIQUES, AND  METHODOLOGICAL ASPECTS.

 vanuit meettechnisch standpunt.]  Translated from Dutch.
 Ingenieur, T9.(49):A72Z-A729,  Dec. 8, 1967.  6 refs.

 When establishing guidelines for the permissibility of
 certain quantities of  air pollutants, survey experiences,
information concerning the relationship between the
concentration of the pollutant, the duration of exposure,
and the effects must be considered.  The height of peak
concentrations and the duration of sampling are inter-
related: measurements of a  shorter duration give higher
peak concentrations than measurements  with a longer
sampling duration.  This means that the sampling time
should be included in the standard. When a large num-
ber of measurements  are made at the same location,  the
frequency of occurrence  of the concentrations will show
a log-normal distribution.  On probability paper,  this
distribution is represented by a  straight line.  This
means that when a maximum  allowable concentration is
set,  this concentration will in practice be exceeded
sooner  or later.   In a standard,  not only a maximum
allowable concentration  should be given, but also the
number of times per year that it may be exceeded.  The
best way to  set a standard is  to give a frequency line on
probability paper,  or  a combination of frequency lines.
The frequency distribution of the concentration of an air
pollutant should, in practice, be below this  line, to con-
form with the standard.   Since the experiences on which
a standard is based are  closely connected to the method
of measurement,  the method  should be part of the stand-
ard.  The total emission of SOz in the Netherlands is
expected to  remain about constant, though there will be
a shift from  SOz production by domestic heating (low
chimneys) to that by industrial sources  (high chimneys).
Since SO£ will continue to be  a major air pollutant,  the
need for an  air quality guide for sulfur is not eliminated
by the coming  of sulfur-free natural gas.

15, 1967.  20 refs.

The concept of tolerance levels is discussed from a
medical viewpoint.  Standards for air quality are a con-
sequence  of a multidisciplinary approach.  The  choice
of tolerance levels is based on qualitative, quantitative,
and tolerative criteria.   The environmental hygienist
should provide medical guides that apply to realistic ex-
posures of population groups, that is, the phenomenology
of atmospheric pollution, which can be characterized by
cumulative frequency distributions over a year.  Avail-
able data  from various epidemiological investigations
have been evaluated in terms of dose-effect relationships
for SO2 and smoke.  The results  could be transformed
in response curves on probability paper for varying com-
binations  of concentrations and exposure times.  These
graphs are directly comparable with cumulative fre-
quency distributions of pollutants. Application  of medi-
cal criteria of acceptability to the effect-exposure dia-
grams results in a bordering of concentrations  of SO2
and days of exposure per year that can be tolerated from
the medical point of view in prevailing areas of the
Netherlands, where the  ratio of SO2 to standard smoke
is about four to one.

Experimental studies are  reported on the simulated
oxidation of sulfur dioxide in atmospheric air. It was
observed that the  higher the air  current velocity,  and
the higher  the relative humidity,  the more marked the
decrease of SO2 concentration.  Sulfuric acid studies
showed that it is produced by oxidation  of SO2 in the air
and that the coexistence of NO2, O3 or  H2O2 enhances
the production of H2SO4.  Microscope studies of the
sulfuric acid mist formed by SO2 oxidation revealed
that the presence  of particulate matter  contributes to
the formation of the acid mist.  Electron microscope
studies substantiated results by showing that samples
of city air  contained particles similar to sulfuric acid
mist particles obtained experimentally.

 ON THE ATMOSPHERIC OXIDATION OF SULFUR DI-
 OXIDE.  Translated from  Japanese. Rodo Kagaku,  41
 (10):501-511,  1965.   19 refs.

 Basic studies were conducted on the behavior of SO2,
 which is most representative of gaseous atmospheric
 pollutants, and the effect of atmospheric conditions
 were followed.  The first study was to  follow the time
 changes  in the decrease in SO2 concentration within a
 sealed container  especially with respect to the rate of
 air flow, humidity, or presence of particulate matter.
 It was found that  high air circulating rate  of high humid-
 ity increased the rate of decrease in SO2 concentration.
 This rate also was greater when particulate matter was
 present than when there was none.  This means that the
 oxidation of SO2 is favored by high circulating rate,
 high humidity,  or the presence of particulate matter.
 Qualitative and quantitative tests were  conducted on the
 formation of sulfuric acid  by the atmospheric oxidation
 of SO2 or by the reaction of SO2 with other gases pre-
 sent in the atmosphere.  A known concentration of SO2
 was generated into a 27 m^ chamber, and the H2SO4
 mist generated was analysed.  This was followed by
 studies of the reactions between SO2 and other gases in
 20 1 and 5  1 reaction bottles under fixed conditions, and
 the products of these gaseous reactions were analyzed.
 The results verified the production  of H2SO4 from SOz.
 It was found that  there was much greater production of
 H2SO4 from SO2  when other gases such as NO2, ozone,
 or H2O2  were present.rather than SO2  alone.  The H2SO4
 mist produced from  SO2 was  observed  under a micro-
 scope, and it was verified that liquid droplets (H2SO4)
 were being formed in the atmosphere.  It was found that
 the presence of particulate matter greatly accelerated
 H2SO4 production. It was found that the atmosphere  of
 an urban area also contains particles similar to the mist
formed in the experiments.  This was verified by elec-
tron microscopy.  (Author's summary)

 J.  Chim.  Phys., Vol. 21,  p. 25-44,  1924.

 The process of peroxidation of nitrogen oxide, whose
 speed increases as the reaction temperature drops, is
 a purely chemical process  in flat contradiction with the
 general rule that the speed of a reaction increases with
 the rise in temperature.  A systematic study of this
 phenomenon, measuring the reaction speed at increasing-
 ly low temperatures  was  conducted.   By means of suit-
 able apparatus and operating methods, the process of
 peroxidation over a temperature range from +75°  to
 -193°,  was observed.  For various temperatures  with-
 in that  range,  the absolute  constants of speed as well as
 the temperature coefficients were determined.  To show
 clearly the influence of temperature as it occurs in
 practice on nitrous gases,  whose composition is general-
 ly given in percentages of NO by volume, the values for
 the relative constants and the half-reaction times  for
 various temperatures above and below 0° were calcu-
 lated.  The half-reaction times are particularly interest-
 ing to consider, since because of the  formation of N2O3
 they indicate good conditions for recovering  nitrous
 mixtures.   To bring  out the effect of refrigeration at
 -183° and  for a mixture containing 1 percent NO in air,
 a mixture  about the same as the gas from an arc furnace,
•the half-reaction time is  58 times shorter than at  ordi-
 nary temperatures.  Intense refrigeration of the nitrous
 gases will thus make it possible to reduce the volume
 of oxidation chambers  by very large proportions.

 with chronic aspecific inflammation, and for persons
 with bronchopulmonary neoplasms.   The literature is
 reviewed; the question of a histopathological classifi-
 cation of inflammatory and tumoral lesions is discussed.
 The histochemical data show that in chronic inflamma-
 tory conditions of the  bronchi there is more nuclear  DNA
 in the basement and intermediary layers of the bronchial
 epithelium than in these same  layers in healthy subjects.
 The DNA levels for  bronchopulmonary  carcinoma do not
 differ from those for other tumors of the  same kind
 located in other portions  of the air passages (nose,
 larynx). Jackson's  adenoma shows an average nuclear
 DNA level  which is much lower than  that found in  epithe-

AND OZONE. II.  [Die Reaktion zwischen Stickstoff-
pentoxyd und Ozon. II.]  Translated from  German.   Z.
Physik. Chem. Abt. B (Leipzig/Berlin), £(4):267-281,
1929.

The reaction between nitrogen pentoxide and ozone was
studied in an apparatus which permitted simultaneous
photometric and manometric measurements.   The con-
centrations of each component were varied over a wide
range. A reaction mechanism was formulated which
indicates that NO3 is formed as an intermediate product.

857-869, May 1906.

The behavior of a gas mixture  containing NO and NO2
in sulfuric acid and sodium hydroxide was investigated
with the result that for analytical purposes sulfuric acid
is the only absorption liquid for the gas mixture.  Also
the behavior of nitrogen oxide in the presence of oxygen
and water was  studied together with the kinetics of
nitrogen oxide  oxidation with oxygen or air.  The kinetic
curves indicated that the reaction 2NO+ O2 = N2O4 takes
place  at a constant rate which indicates that the oxidation
takes  place directly without formation of ^Oj as an
intermediate.

THE SEARCH FOR GASEOUS COMPOUNDS AND THE
STUDY OF SOME OF THEIR PROPERTIES WITH THE
HELP OF THE SPECTROSCOPE.  [De la recherche des
composes gazeux et de 1'etude de quelques-unes de leurs
proprietes a 1'aide  du spectroscope.J Translated from
French. Compt. Rend. (Paris), Vol. 90,  p. 80-82,
1881.

It has been discovered that the gases which issue from
the electric discharge apparatus of Berthelot can be
studied with a spectroscope.  Traces of ozone can be
detected when a sufficiently long gaseous  column is used.
The method has been used to study the destruction of
ozone by heat and to study the products  obtained by the
electrification of a mixture  of nitrogen and oxygen.  It
was found that the bands of absorption of pure and dry
ozone, prepared •with oxygen from which all of the
nitrogen has been  removed, disappear slowly at ordinary
temperature and rapidly at red-hot temperatures.  By
avoiding the use of high electric voltages, the discharge
apparatuses can be used to prepare  ozone in the pre-
sence of nitrogen without the formation of hyponitric
acid.   The experiments can be easily interpreted if the
idea of the formation of a pernitric acid,  obtained under
conditions similar  to those which were used by Berthelot
to discover persulfuric acid,  is accepted.

p. 1111-1114, 1882.

Nitrogen peroxide formed when ozone is prepared by
electric discharge in dry air was investigated.  The
rate at which the peroxide is formed was studied by
spectroscope.  Also its conversion into another oxide
was  studied by pressure measurements.  Emphasis is
also placed on the breaking down of pernitric acid to
hyponitric acid.

THE RATE OF THE REACTION BETWEEN NITRIC
OXIDE AND OXYGEN.  [Die Geschwindigkeit der Reak-
tion zwischen Stickoxyd und Sauerstoff,]  Translated
from German. Elektrochem.  angew. Physik.  Chemie
(Weinheim), 2_4(13/ 14): 1 83-Z01, July 1,  1918.  30 refs.

The oxidation of nitric oxide with oxygen was studied
kinetically by pressure recordings at temperatures from
0 to 90° C. The reaction took place according to the
third order process 2NO+ O£ = 2NO2.   The rate was
independent of NO2, H2O and SO2 admixtures.  The
experiments proved that Raschig was incorrect when he
assumed that NO is first rapidly oxidized to N2O3 which
is then slowly converted to NO2.

THE SPEED OF THE COMBINATION OF NITRIC OXIDE

Z. angew. Chem. (Weinheim), Vol. 31, p.  145-148,
July 30,  1918.

The reaction rate of nitric oxide with oxygen •was deter-
mined by  batch experiments.  The conversion rate was
determined from the measured pressure change.  Ex-
periments were also made to elucidate  possible side re-
actions and catalytic effects.  The result of the study
indicates  that  the reaction takes place according to the
trimolecular equation 2 NO + O^ =2 NO2 and not as sug-
gested by Raschig by a two stage reaction with ^03 as
an intermediate.
The formation and decomposition of higher nitrogen
oxides was studied by determining the equilibrium con-
stants of the  reactions 2NOz «—>NzO4 in the temperature
range of 9-115° C and 2NO2 <—» 2ND + O2 in the range
of 225-550° C.  Expressions for the logarithm of the
equilibrium constants as a. function of temperature were
obtained.  Also the rate constants  of the  reaction 2NO +
O2 = 2NO2 was determined in the temperature range of
140-390° C.  Reaction mechanisms are discussed.

EFFECT QF CARBON MONOXIDE ON YEAST METAB-
OLISM.  [Uber die Wirkung des Kohlenoxyds auf den
Stoffwechsel der Hefe.]  Translated from German.
Biochem. Z. (Heidelberg), Vol.  177, p.  471-481, 1927.
28 refs.

The effects  of carbon monoxide on respiration and fer-
mentation of bakers yeast  and the effects of light inten-
sity and wavelength on the  yeast metabolism were
studied.  The results showed that the respiration fer-
ment of the  yeast combines with carbon monoxide.  In
the presence of carbon monoxide and oxygen at a given
carbon monoxide pressure the  inhibition of respiration
is indirectly proportional to the partial oxygen pressure.
The compound formed by combination of the respiration
ferment with carbon monoxide  is dissociated by light
and absorbs at wave lengths of 436, 546,  and 578.

VDI Forschungsheft, No.  483, p. 49-52, 1961.  58 refs.

The effect of the  interval  of measurement in computing
maximum concentration values of gas diffusion in tur-
bulent flow is illustrated.  The connection between  the
concentration of a gas escaping continuously from a
source and the meteorological parameters  is treated
mathematically using the  Suttom formula.  It is  shown
that three time parameters,  the interval of  measure-
ment  (for concentration measurements), the emission
time (for the influence of  the  gas) and the observation
time (for measuring meteorological parameters) must
agree.

were determined.  The concentration ratio of SO2 to
total sulfur oxides decreased with increasing distance.
This clearly indicated that SC>2 was oxidized in the at-
'mosphere.  The intensity ratios of solar radiation meas-
ured in fine weather  in the Zao and Tokyo  areas  agreed
extremely well in the range of the wavelength 400 mji to
320 mji.  However, there was a big difference below 320
mji.  From experiments with a. mercury lamp it  was
found that the photochemical oxidation of SO^ "was a first
order reaction and that the rate constantly increased
with an increase in atmospheric moisture.   Parameters
tabulated for 10 to 32 different measurement locations
include:  concentration of SO^ and of total sulfur oxides;
temperature; wind direction and speed; weather; and
correlation of total sulfur  oxides with distance from the
slag dump pollution source.
