                  Air pollution is a major problem in environmental health, a problem that grows
              more severe as our population expands.  For the protection of health and well-being
              in our Nation's communities, we must control contamination of the atmosphere.  Meth-
              ods of reducing  air pollution must be based upon  data concerning pollutant levels—
              upon atmospheric measurements that define the air pollution problem.  Such infor-
              mation is being  provided through several comprehensive  programs of atmospheric
              sampling conducted by the Division of Air Pollution and by numerous State and local
              agencies.   Analysis of this  information allows the  assessment of past and present
              contamination levels, and is useful for the prediction of future control requirements.
                  This report of air pollution measurements of the National Air Sampling Network
              for the period 1957 to 1961 is the second major compilation of Network data.  As our
              programs for the surveillance of air quality are continued, it is hoped that concurrent
              gains will be made in the overall abatement of air pollution, both in individual com-
              munities and  on a  national scale.   In  the coming years, then,  these reports of  air
              pollution  measurements might  constitute  a  record of our Nation's  progress in  the
              fight for cleaner  air.
                  Acknowledgment is  made  of  the  valuable  assistance provided  by State health
              departments, Federal agencies,  and Regional Offices of the Public Health Service in
              setting up and maintaining  the Network.  The  generous cooperation of many local
              participating agencies  and the  large number of station operators who have given
              freely of  their time  is acknowledged and appreciated.  Without this assistance,  the
              operation  of the National Air  Sampling Network would  not be possible.

         PART   1—THE   NATIONAL  AIR  SAMPLING   NETWORK
INTRODUCTION

  The events of recent years have served to focus the attention
of the public  on the problem of air pollution.  Since World
War-II increasing numbers of communities have experienced
the adverse effects of atmospheric contamination.  Realizing
the importance of maintaining the quality of the atmosphere at
a safe level, many State and local governing bodies have passed,
and others are seeking to  pass, legislation aimed  at controlling
the emission of contaminants to the atmosphere.  The formula-
tion of adequate control  measures is contingent upon knowl-
edge of the nature and the  effects of air pollution.  Such knowl-
edge cannot  be obtained  without  routinely  analyzing the air
for various chemical constituents.
   In an attempt to provide the basic data necessary  to char-
acterize the problem of air pollution, the Public Health Service
in 1953 established an air sampling network.  The Federal Air
Pollution Research and Technical  Assistance Act (Public Law
159, 84th Congress), under which the program is currently ad-
ministered, became effective in June 1955.
   The objectives of the National Air Sampling Network were
specifically defined.  They include the determination of  the
extent and the nature of  air pollution  as well as the study of
trends in the  levels of various atmospheric  contaminants  and
the  investigation  of  relationships between  air pollution  and
socioeconomic,  geographic, topographic, meteorological,  and
other factors.   The data acquired are useful  in planning epide-
miological investigations  and  also  provide the background
against which more intensive community and statewide studies
of air pollution can be conducted.
   Initially, the operations  of the network included the collection
and analysis of suspended particulate matter only.   More re-
cently,  activities have been expanded to include  the collection
and analysis of precipitation samples and the determination of
the level of atmospheric contamination by specific gaseous pol-
lutants.  This  report is limited to presenting and  discussing
the measurements made on the suspended particulate matter for
the years 1957 to 1961.  A report summarizing the particulate
data collected during the years 1953 to  1957 was published in
1958 (1).  Technical papers relative to the  operations of the
network and the interpretation of data also have been presented
(2,3,4,5).

Historical  Background
   Initially, in cooperation with State and local health depart-
ments  and air pollution control agencies, air sampling stations
were set up in 17 communities.  Then, as now, the  field opera-
tions were carried out on a voluntary basis by the  local agencies
with sampling  equipment  and laboratory services supplied by
the National Air Sampling Network.   During the  years 1954
to 1956, as a result of the desire of additional communities to
participate in this effort, other stations were activated, bringing
the total to 66.

Operations:  1957  to  1961
  Major revision of the  network operations was initiated on
January  1, 1957.  With  these revisions the network  became
truly "national."  There are currently 250 sampling stations in
the network, 213 urban and 37 nonurban.   Of the urban sta-
tions, 73 sample every year and 140 sample every other year
(fig. 1.1).  Thus, in any one year there are 180 stations actively
collecting samples,  143 urban and 37 nonurban.
  Every-year urban sampling stations are usually located in  the
largest city (in terms of population)  in each of the 50 States,
the District of Columbia, and Puerto Rico.   In the more popu-
lous States there are several every-year urban sampling stations.
By  collecting samples every other year at additional stations at
least a minimum of data concerning particulate air pollution is
available for most of the major urban areas in the United States.
In Massachusetts,  New York, and Texas, stations originally
scheduled to collect samples on an every-other-year basis were
in fact  operated as every-year  stations.   These stations were
maintained during the off years by the respective State agencies.
  Nonurban  station  locations include various  topographical
categories  such as farmland, desert, forest, mountain,  and
coastal.  The nonurban stations were  not specifically selected
to be "clean air" control sites for urban areas, but they  do pro-
vide for a relative comparison between some urban and nearby
nonurban areas.

ATMOSPHERIC  POLLUTANTS
MEASURED
  Pollutants may be classified into two types:  (a) gases or
vapors, (b)  particulate matter consisting of  solid particles and
liquid droplets. Particulate  matter  may be further  divided
into two categories: (1) large particles that settle rapidly,  (2)
small particles that remain in suspension in the air for varying
periods of time.  These latter, called suspended particulate mat-
ter, are the type of particulate matter collected by the National
Air Sampling Network.

Suspended Particulate Matter
  Polluted atmospheres contain varying quantities of suspended
particulate  matter, known  technically as aerosols.  This  sus-
pended particulate matter consists of smoke, dust, and fumes,
which are  solid, and droplets  of viscous liquids.  Suspended
particulate  matter varies  in size from well below 1 micron to
approximately  100 microns, a  micron  being  approximately
1/25,000 of an inch.  Among the effects of particulate pollutants
are reduction of visibility, soiling and deterioration of materials,
plant damage, irritation of tissue, and possible damage to health.

  This particulate matter may arise from a great many sources:
incomplete combustion of solid, liquid, or gaseous fuels; wastes
from metallurgical, chemical, and refining operations, incinera-
tion, and numerous  other processes; and  natural phenomena
such as dust storms, volcanic eruptions, sea spray, etc.  The
determination of the composition of suspended particulate matter
in the atmosphere sheds light on the nature of particulate pollu-
tion.  A detailed chemical analysis of particulate samples from
urban and nonurban  areas provides basic data that is valuable in
the overall attack on  air pollution. Such data may be useful in
pinpointing sources  of pollution and in  predicting potential
health  effects.

Organic  Pollutants

  That fraction of particulate matter that  is soluble in  benzene
is classified in this report as benzene-soluble organic matter, or
simply organic matter.
  A wide variety of liquid and solid organic materials are poured
into  the  atmosphere.   Among  these are substances that may
cause irritation of biological tissue.  Compounds that produce
cancer in experimental animals have been isolated from atmos-
pheric organic matter.

Inorganic Pollutants

  In contrast to the "tarry" organic matter, inorganic solids in
the air are gritty, ash-like, or crystalline.  A very large number
of such pollutants have been identified.  Since many inorganic
materials can be related to specific  industrial  processes  and
operations, their presence in the air can often be used to ascer-
tain  sources of pollution.
   Sulfates.—In addition to the  liquid sulfuric acid contrib-
uted  to  the atmosphere by various  industrial  processes,  a
considerable amount may result from that portion of the atmos-
pheric sulfur dioxide which is converted to the trioxide and then

-------
to sulfuric acid in the presence of water vapor.  This acid reacts
with other substances in the air to form sulfates.  Most of the
sulfur dioxide arises from the combustion of fuels.  Therefore,
the particulate sulfate level  may reflect the fuel consumption of
a community.  Since many sulfates are acid, they generally have
corrosive properties.
   Nitrates.—Nitrates  arise in the air in  a manner similar to
sulfates.   Nitric acid  and oxides of nitrogen come from indus-
trial operations  and  various  combustion  processes.   The
presence  of  nitrates  increases the corrosive property of the
atmosphere.
   Metals.—A large number of metals,  metal oxides,  and salts
are released to the atmosphere from a wide variety of industrial
processes, urban activities, and natural  sources.  Since  the
effluent from a particular industry is limited to the raw  materials
involved, identification of metals in atmospheric samples may
be of use in detecting sources  of pollution.
   Many metals are known to be toxic  at certain concentrations.
Potential problem areas may be defined on the basis of data ob-
tained by the analysis of samples of suspended particulate matter.
Emission spectrographic procedures are employed for  the  meas-
urement of metals, and it is possible to analyze  a single sample
for a large number of metals with little more effort than required
for a few.  This  has  made possible the accumulation of a great
deal of basic information on the concentrations of many metallic
pollutants whose hygienic  significance has not as  yet  been
determined.

Radioactive  Materials
   The rapid increase in the use of atomic energy for industrial,
medical,  and military  purposes has stimulated interest in the
measurement of the  radioactivity in  the  atmosphere. Radio-
active materials  are  unique in  that they may be detected from
sources several thousand miles distant.  This detection is made
possible by the  supersensitive methods available for the  deter-
mination of  radioactive materials, as compared to the  lower
sensitivity of the chemical  methods used for the other analyses
reported herein.
   While the determination  of /3-radioactivity is  not a major ob-
jective of the National Air Sampling Network these  measure-
ments have been made since the early days of the Network and
for a  time represented the  major source  of such information.
Since 1956 the National Radiation Surveillance Network has col-
lected information on the radioactivity in the atmosphere.   In-
formation concerning this activity is available from the Division
of Radiological Health, Public Health Service, U.S. Department
of Health, Education, and Welfare, Washington 25, D.C.

SAMPLING EQUIPMENT

   Suspended particulate samples are obtained  with a high-
volume air sampler (fig. 1.2), which draws air through an 8- by
10-inch  glass-fiber filter (fig.  1.3) capable of  removing prac-
tically 100 percent of all particulates 0.3 micron, or greater, in
diameter.   During each scheduled sampling period the sampler
is operated for 24 hours.
   At most urban stations airflow rates average about 40 to 50
cubic  feet per minute.  At nonurban  stations the  rates are
higher, usually averaging in the 55 to 65 cfm range.  Since air-
flow progressively diminishes as particulates accumulate on and
increase the flow of resistance of the filter, all samplers are set to
operate initially at about 55 to 65 cfm.  On the assumption that
the flow rates decrease uniformly  during the sampling period,
the volume of air filtered is taken as  the product of  the time
interval and the average of initial and  final flow rates observed
during each sampling period.
          FIGURE 1.2—HIGH  VOLUME AIR SAMPLER.
       FIGURE 1.3—FILTER AND MAILING CONTAINER.

-------
  In urban areas with high levels of participate air pollution the
loading on the filter builds up quickly and some types of particu-
late matter cause clogging of the filter. This clogging may result
in a nonlinear decrease in the airflow, and the average  airflow
computed as stated above  may differ  considerably from the true
flow.   To evaluate the error resulting from such a nonlinear re-
duction in air flow, flow regulators were used experimentally in
Baltimore, Md.,  Dayton. Ohio,  and Pittsburgh,  Pa.,  during
1960 (6, 7).  The flow regulator maintains a nearly constant
airflow of  35 to  40 cfm  over the 24-hour sampling interval.
Based upon the favorable experimental results observed in the
three cities mentioned previously, air samplers in other cities
will be equipped  with these flow regulators.
   The shelter for the sampler, which may be converted  readily
 into a shipping container, is shown as it is mounted at a typical
 sampling site (fig. 1.4). To insure a high degree of uniformity
 in filter exposure, the sampler is oriented so that the  filter is
 horizontal and facing upward.  Data from  10 cities for a year
 show that the average sampler flow results in an average velocity
 of 64 fpm across the horizontal  air inlet  portal of the  shelter.
 Since flow is vertically upward, collection at this  velocity is
 limited to  particles 100 micron and less in diameter.
   As soon as possible after collection, the filter is folded care-
 fully, placed in  a manila folder, and  mailed to the Network
 laboratory in  Cincinnati, Ohio.   Upon  receipt, the filter is
 weighed and divided into aliquots of suitable size for chemical
 analyses.

 SELECTION  OF  STATION   LOCATIONS

   It would  be desirable to collect  samples at more than one
 location in each city, but for the number of cities  in  the net-
 work such a program would be economically unfeasible.  In
 addition, the National Air Sampling Network is not designed to
 substitute for intensive air pollution studies on a State  or local
 level.  For these  reasons,  the Network utilizes only one sampling
 site in each urban area Wherever possible, the station is located
 in a central business district and the sampler is placed not more
 than 50 feet above ground level.  For nonurban stations  location
 is not critical, since immediate sources of high emission are not
 a problem.
    Recently the Public Health  Service conducted an intensive air
 pollution  study  in  Nashville,  Tenn.  (8).   Measurements of
 suspended particulate matter with high-volume air samplers at
 11 locations, 7 urban and 4 nonurban, afforded an opportunity
 to investigate the geographic variability of air pollution within
 a city.  Analysis of these data  showed that  it is unlikely that
 measurements from any one station  will be representative of the
 city as  a  whole  (9).  The results indicate that  an average of
 measurements obtained at a station in  the central business dis-
 trict and  a  nonurban station provides a  reasonably good esti-
 mate of the mean of the entire city.
    In the interpretation of the data  presented in this report one
 must consider the limitations that are imposed upon these data
 by the design of the Network.  As mentioned previously, meas-
 urements  of particulates are  obtained at  one site in each com-
 munity.   Even though precautions  are taken to insure that the
 sampling  site is  as  representative as possible of the urban area
                FIGURE  1.4—TYPICAL SITE.

as a whole, it is impossible to be certain that the measurements
obtained at a specific site are not sometimes unduly influenced
by local factors.   Such factors might include topography, struc-
tures, and sources of pollution in the immediate vicinity of the
site, and other variables, the effect  of which cannot always be
accurately anticipated.  It must be kept in mind then, that when
comparisons are made among pollution levels for various cities,
they are valid only insofar as the sites are comparable.

SAMPLING SCHEDULE

  The sampling  schedule used  by  the Network calls for the
collection of one 24-hour sample during each  2-week sampling
period, or 26 samples per year.   Schedules are prepared in ad-
vance for a full year and sent to each station in the Network.
Currently the sampling procedure provides for the collection of
a sample during  the first week of the 2-week  sampling period.
If for some reason a sample  is not collected on the specified
day, a makeup sample may be taken during the second week.
  The method for randomly selecting the sampling starting time
and the sampling day has been described in detail(l).  Briefly,
all  possible starting times (the hours 8 a.m. to 3 p.m.) for each
of the 7 days in a week are listed  and numbered sequentially.
From a  table of random numbers, 26 numbers  are selected.
Each number is then interpreted as an hour and a day of week
from the listing just described.  Finally,  the day of week is
converted to the appropriate calendar day.   The station opera-
tor is free to start the sampler at any time during the designated
hour.

VALIDITY  OF BIWEEKLY  SAMPLING

  The validity of biweekly sampling as compared with more
frequent sampling was treated at length in the previous Net-
work  publication using  data from Philadelphia,  Pa.  (1).
Since that publication is out of print and thus unavailable as a
reference, the following resume of the discussion concerning the
validity  of biweekly  sampling is presented here.
   In Philadelphia the high-volume sampler located at City Hall
annex was operated more or less continuously during 1955 and
1956.   A total of 596 samples was collected: 289 in 1955, and
307 in 1956.   From this complete set of samples a smaller set
was selected for each year according to a random schedule pre-
pared  in the manner previously  described.   This produced  a
set of 25 values for each year, 1 less than the number prescribed,
because  of a shutdown during one of the sampling periods each
year.  The set of values selected differed  from a true random
sample in that the time of starting the sampler was more or less
the same.  This deviation from a truly  random sample should
not alter the results.
  The level of total suspended particulate  matter was used for
a statistical comparison of daily and biweekly random sampling
for 1956. The results of this comparison are presented in table
1.1.  For reasons noted in Appendix A the statistical analysis was
performed on the logarithms of  observed values; thus mean
concentrations are presented  in the form of geometric  means.
  The cumulative frequency distributions for the two different
sets  of samples for 1956 are plotted on logarithmic probability
graph  paper  (fig. 1.5).  As  would be expected  on theoretical
grounds, because of the larger amount of data the set of daily
observations  is more  nearly log-normally distributed than the
smaller set of biweekly observations; nevertheless, the smaller
sample exhibits log-normal characteristics.

   The estimate of the geometric mean computed from the 25
 random observations  was in this instance approximately equal
 to the estimate provided by the daily sampling: the values were
 203 and 200 ^g/m3, respectively.  Likewise, other sampling sta-
 tistics computed  from  the biweekly random sample  deviated
 only slightly from those computed for  the  daily sample.
   The preceding analysis was based upon a comparison of samp-
 ling methods for one  year.  A 2-year comparison of biweekly
 random and daily sampling was also made for Philadelphia for
 the years 1955 and 1956.  Results are presented in table  1.2.
 Estimates of the geometric mean concentration  for  the  two
 sampling methods are 192 ,ug/m3 for biweekly random and 200
 /ig/m3 for daily  sampling.  The percentile values  also agree
 quite well.
   Another test of the  reliability of a selective method of samp-
 ling is its ability to detect unusually high concentrations of par-
 ticular contaminants.  For this purpose the 95th-percentile value
 (i.e., the concentration  exceeded  5 percent  of the time) is of
 particular interest.  Toward this end the upper 90 percent con-
 fidence limit of the 95th percentile was computed for the 1955-56
 data by a method of Eisenhart, Hastay, and Wallis (10), which
 makes use of the sample mean and standard deviation.  The
 limits were  found to  be  350  ,ug/3 for the biweekly random
 sample  and 370 /ag/m3 for the  larger daily sample, a difference
 of only 6 percent.  Thus on the basis of calculation from  50
 samples randomly selected one  can say with 90 percent confi-
 dence that under environmental conditions existing at sampling
 site 1 for 1955 and 1956 not more than 5 percent of the 24-hour
total suspended particulate concentrations exceeded 350 /ug/m3.
  The data from the Nashville study also afford an opportunity
 to compare the results  of biweekly sampling with daily sampling
 (9).  The annual mean particulate concentration at the central
business location, computed from samples collected daily, was
found to be 157 ^g/m3 as opposed to 160  /ng/m3 for samples
collected on 26 days selected at random, with one for each 2-week
sampling period.

  For the entire city of Nashville (seven urban stations) the
annual  mean computed from  samples collected daily was 125
 ,u.g/m3;  the annual mean computed from samples collected on
only  1  day during each 2-week period was 143 //.g/m3
 SUMMARY  OF FINDINGS

 Mean and  Maximum  Concentrations

   The analytical results from 18,608 samples (14,494 urban and
 3,114 nonurban)  collected during the years 1957 to 1961 are
 summarized briefly (table 1.3).  Because of the extremely low
 levels of all pollutants at  nonurban sites, only  suspended parti-
 culate  matter and the  benzene-soluble  organic fraction are
 routinely measured on nonurban samples.
   Suspended  Particulates.—The  national urban  mean*
 concentration  of suspended particulates for 1957 to  1961 was
 104  /ug/m3  with  a maximum concentration  of  1706  /^g/m3.
 The  frequency distribution of mean concentrations, which for
 190  cities ranged from 46 to 224 /ug/m3 (table 2.3), is shown
 graphically in figure 1.6.   For 50 nonurban areas the national
 mean concentration  was 27 /xg/m3, with means  for  specific
 sampling sites ranging from  7 to 59 ,ug/m3 (table 2.6).
   In general the mean level of suspended particulates for urban
 areas was nearly four times that for nonurban areas (table  1.3).
   Benzene-Soluble Organics.—The mean  concentration of
 organics for urban areas during 1957 to  1961 was 7.6 /xg/m3,
 with a maximum  concentration of  123.9  /*g/m3 for an  indi-
 vidual sample  (table 1.3). For specific urban stations the mean
 concentrations ranged from  2.2 to 19.2  p-g/m3  (table 2.10).
The distribution of means for all urban areas is shown in figure
 1.7.  In general the mean concentration of organics for urban
 areas was about five times that for nonurban stations (table  1.3).

   Radioactivity.—Interest in measuring the radioactivity of
the atmosphere has been stimulated by the ever-increasing uses
of atomic energy for industrial and medical purposes and by
the occurrence of fallout in the testing of nuclear devices, which
are primarily military.   Generally the sources of such contami-
nation are beyond the control of city and State agencies.   Since
the beginning of the National Air Sampling Network, measure-
ments of beta-radioactivity have been made on most particulate
samples collected.  The mean  monthly  level of  atmospheric
radioactivity on a national basis for urban  and nonurban sta-
tions combined for 1957 to 1961 is shown graphically in fig. 1.8.

Several peaks are immediately obvious.  The occurrences of
these peaks have been shown to be directly associated with the
testing of nuclear  devices (5).  Following the termination of
such tests in  1958  the levels of radioactivity dropped and were
barely detectable until the fall of 1961, when testing was re-
sumed and measurable quantities of radioactive debris again
appeared in the atmosphere.

Trends  in Levels  of  Air  Pollution

  The annual mean concentrations of suspended particulates for
all urban  sampling stations (table 2.1)  is shown graphically in
figure  1.9. Based upon these data, there appears to be about a
5 percent reduction in  the  mean level each year.   Since the
structure  of  the network changes from year to year, the data
                                   probably do not represent a true picture of the trend.   There-
                                   fore, the annual mean for the every-year urban stations is also
                                   shown.
                                      The mean level of suspended particulates for the every-year
                                   urban stations is higher than that for all urban stations.  This
                                   is as expected, since the every-year stations are primarily in the
                                   largest cities.
                                      For the every-year stations the level of suspended particulates
                                   appears  to have changed little from  1957 to 1960; however,
                                   there was a pronounced decrease from 1960 to 1961.  Whether
                                   this abrupt change  is indicative  of a trend or is an anomaly
                                   due to a difference in the weather pattern for 1961 can be de-
                                   termined only after data from additional years become available.

                                   Air Pollution  and Population

                                      Each  city that has a Network sampling station is classified
                                   into one of eight  broad population  categories  according  to
                                   1960 census figures  (part 3).   The category  to which each
                                   has been assigned is included with the site description.
                                      Data on suspended particulates and benzene-soluble organics
                                   for  1957 to  1961 are summarized  by population category  in
                                   table 1.4.  The  mean concentration for each population cate-
                                   gory is shown graphically for suspended particulates in figure
                                   1.10 and for  organics in figure 1.11.  A  relationship between
                                   population and air pollution is indicated, in that the concentra-
                                   tions of both types  of pollutant are significantly higher  for
                                   the larger  cities.   For example, the mean concentration of or-
                                   ganics for the cities with the largest population was 13.5 jiig/m3,
                                   whereas the mean for cities with population less than 25,000 was
                                   3.6 //,g/m3
                                      Using National Air Sampling Network data for the years
                                   1957 to  1959, Hilst and Bryan (11) also studied the relationship
                                   between air pollution levels and  population.   They  concluded
                                   that the concentration of both suspended particulates  and or-
                                   ganics is proportional to a power of the total population.

 Air  Pollution and Topography
   Each nonurban station is classified into one of eight topo-
 graphic categories  (part  3).   These categories, admittedly
 somewhat  arbitrary, are based upon geographic location and
 land use.  The category to which each nonurban station is as-
 signed is included with the site description.
   Data on suspended participates and benzene-soluble organics
 for  1957 to  1961 are summarized by topographic category in
 table 1.5.  Since for nonurban areas the atmospheric concen-
 trations of both types of pollutant are quite low, it is quite doubt-
 ful that significance can be attached to the slight  difference in
 the  mean  concentrations of the pollutants for the respective
 topographic categories.

 Geographic Pattern of Air Pollution in the United
       States

   The  geographic pattern of air pollution is shown by plotting
 the mean urban concentration of suspended particulates for each
 State on a map of the continental United States (fig. 1.12).
   In interpreting the map it should be recognized that data from
 each State was provided by volunteer cooperation in that State.

                                           The extent of coverage both in terms of years sampled and num-
                                           ber of stations varied with the extent of local participation ob-
                                           tained  (for example, see table 2.2).   In order to make figure
                                           1.12 complete, data were included from one or two States from
                                           which inadequate data were obtained.
                                             With the exception of such States as Arizona,  Nevada,  and
                                           New Mexico, the higher levels of particulate air pollution occur
                                           in the more industrialized, heavily populated areas of the United
                                           States.   Thus  any geographic pattern in air pollution levels is
                                           probably associated with the geographic location  of the larger
                                           urban complexes.

                                           Weekday versus Weekend  Concentrations

                                             The  list of sources that contribute to the air pollution prob-
                                           lem of a community includes not only industrial and commer-
                                           cial establishments but also the activities of the people, such as
                                           the movement of automobiles, home heating, rubbish burning,
                                           etc.  If industry were entirely  responsible for the problem of
                                           air  pollution, then  the  levels  of  atmospheric contamination
                                           should  show a marked decrease during the times when indus-

                       trial activity is at its lowest on weekends.   For determination
                       of such a possible correlation, the mean concentrations of both
                       suspended particulates and organics on weekdays and weekends
                       was computed for urban and nonurban areas, and are presented
                       in figures 1.13 and 1.14.   (A weekend sample is defined as one
                       for which the 24-hour sampling period ended on Sunday.)
                         For  urban areas as a group  the weekend levels  for the two
                       types of pollutants were about  15 percent lower than the  cor-
                       responding weekday levels.   Even though these observed differ-
                       ences are significant statistically, they are not of the magnitude
                       that might  be  expected.  There are probably several explana-
                       tions for this: not all industrial sources of particulate matter
                       are curtailed on weekends; some of the suspended  particulates
                       collected may  have been emitted before the sampling period
                       began;  and, finally, the contribution of certain municipal, do-
                       mestic,  and transportation sources may increase on  the week-
                       end.-''At the nonurban stations no difference is observed between
                       the weekend and the weekday  levels of either  suspended par-
                       ticulate or organic  pollutants.

                                    PART  2—DATA  TABLES
CRITERIA  FOR INCLUSION OF DATA
IN  TABLES
  Each year a schedule is sent to the operator of each Network
sampling station specifying exactly when each sample is to be
collected.  The schedule provides for the collection of 1 sample
in each 2-week interval, or 26 samples per year.  Situations may
arise, however,  in which no sample is collected during the 2-
week interval.   Because of such deviations from the established
schedule, the resulting data might not adequately represent the
sampling year.   For this reason the  following criteria were
established for the inclusion of data in this report:
  1.  A minimum of 20 samples and a maximum of 26 samples
collected during any one year.
  2.  A minimum of 10 and a maximum of 13 samples collected
in each half of a year.
  3.  At most three samples collected in any one month.
  4.  At most seven samples collected in any one quarter.
  5.  Samples collected during  at least 2  of  3 months in a
quarter.
                        REGIONAL  GROUPINGS
                          The regional grouping of States used in this report corre-
                        sponds to the regional organization of the U.S. Department of
                        Health,  Education, and  Welfare.  Geographical  designations
                        have been added, since these names are more meaningful than
                        the numerical designations alone.

FREQUENCY  DISTRIBUTION TABLES-
YEARLY  AND CUMULATIVE

  Frequency distributions  for individual years and cumulative
over the years  1957 to 1961 are presented for suspended par-
ticulate matter, benzene-soluble organics, and the following in-
organic constituents: nitrates, sulfates, chromium, copper, iron,
lead, manganese, nickel, tin, titanium, and zinc.  For suspended
particulate matter the summaries are presented on a national,
regional  (Public  Health Service designation), State, and indi-
vidual station basis for all urban stations (tables 2.1,  2.2, and
2.3).  Because there is only one such station in each State, the
State summaries are not given for the nonurban stations (tables
2.5 and  2.6).  The summaries of benzene-soluble organic data
are presented in a like manner (tables 2.8, 2.9, 2.10, 2.12, and
2.13).   Since  chemical  analysis  for  inorganic pollutants has
been done on samples from only a relatively small number  of
urban stations, summaries for this class of pollutant  are pre-
sented only on a national, regional, and station basis (tables
2.18,2.20,2.22, 2.24,2.26,2.28,2.30,2.32,2.34,2.36, and 2.38).
  The tables show  the number of samples  analyzed, the min-
imum and the maximum concentrations, the arithmetic and the
geometric means, the percentiles of  the cumulative frequency
distribution, and the standard geometric deviation.  The com-
putations necessary to obtain these  statistics were  performed
by  an  electronic computer.  Such entries  as the number  of
samples,  the minimum values, and  the maximum values re-
quire no explanation. The other terms are described  in detail
in part  5.
  Certain other aspects  of the tables require clarification.  It
will be  observed that blank spaces  appear in  some columns,
e.g., chromium data in table 2.22. The blank in the minimum
column indicates that for at least one sample the concentration
of chromium was less than the minimum quantity detectable by
the method of chemical analysis.  Blanks  in the  columns  of
the percent cumulative  frequency distribution indicates  that
quantities of chromium in the corresponding percentage of all
samples were below minimum  detectable levels.  Finally,  if
at least  10  percent of the values  are less than  the minimum
detectable value, the geometric mean and the standard geometric
deviation are not computed, and no entries appear in the tables.

FREQUENCY  DISTRIBUTION TABLES-
SEASONAL

  Seasonal variability is shown for suspended particulate mat-
ter  and  benzene-soluble organics for individual  urban (tables
2.4  and  2.11)  and nonurban stations (tables 2.7 and 2.14).
Data for each  station for all years  are separated into  four
seasons,  the beginning dates of which are as  follows; winter,
December  1; spring, March 1; summer, June 1; autumn, Sep-
tember 1.  The frequency distribution data previously described
are computed for each season.  Because of the small number
of samples seasonal frequency distributions for cities with only
1 year of data may appear erratic.  In such cases no interpre-
tation of the percentiles should be made.

FREQUENCY  DISTRIBUTION  TABLES-
PERCENT  ORGANIC
  For  each sample the percent of the suspended particulate
that is soluble in benzene (percent organic)  is computed.  Fre-
quency distributions for individual years and all years have
been computed on a station basis for both urban and nonurban
stations (table  2.15).  The  content  of these tables  differs
slightly from the frequency distribution tables previously dis-
cussed.  First,  only the 10, 30, 50, 70, and 90 percentiles of
the cumulative frequency distributions of the percent organic
are included.  Second, the correlation coefficient (see part 5),
which  shows  the relationship between  the concentrations of
suspended particulates and benzene-soluble organics is also in-
cluded. The  correlation coefficient can  range in value from
— 1 to +1; in this table the correlation coefficient varies from
near zero (no relationship) to near 1 (when the percent organic
in the particulate matter is nearly constant).

MONTHLY RADIOACTIVITY  TABLES

  The measurements of radioactivity for urban and nonurban
sampling sites have been combined and summarized  by  month
on a national, regional, and State basis (tables 2.16 and 2.17).
Only the number of samples analyzed and the minimum, max-
imum, and arithmetic mean values are given.   On these tables
a blank indicates no  data for a  given month; the  value 0.0
denotes that the level of radioactivity was less than the minimum
detectable amount.  Concentrations of radioactivity  are given
in picocuries (micro-microcuries) per  cubic meter.

QUARTERLY HEAVY, QUARTERLY COM-
   POSITE  TABLES
  These tables (tables 2.19, 2.21,  2.23, 2.25,  2.27, 2.29, 2.31,
2.33, 2.35, 2.37, and 2.39) consist of  raw data obtained from
analysis of (1)  the sample representing the highest concentra-
tion of suspended particulates and, in most cases, (2)  a com-
posite  of  all  samples collected in each  quarter of the year
indicated.

TRACE METALS TABLES

  The  atmospheric concentrations of some of the metals (anti-
mony, bismuth, cadmium, cobalt, molybdenum, and vanadium)
are so low that only an occasional sample shows a value above
the  minimum detectable quantity.   For these metals abbrevi-
ated tables are presented (tables  2.40 through 2.45).   These
tables,  presented for individual stations only, contain the num-
ber of samples analyzed, the number of values above minimum
detectable, and the maximum value.

                  PART  3—SAMPLING   SITE  DESCRIPTION   AND
                               PARTICIPATING  ORGANIZATION
   Based upon data supplied by the local operating agency, ur-
ban stations are classified  with respect to the general area in
which they are located: commercial (C), industrial (I), or resi-
dential  (R).   For stations located in areas that encompass two
or more of these categories, the appropriate letters are shown.
Following the area code letter is the height (in feet) of the air
sampler above ground  level.   The  population category  (PC)
indicates population (based upon the 1960 census)  according
to the following classification:
                        Population range
                      50,000-100,000	
                      25,000-50,000	
                      10,000-25,000	
  Population range
 More than 3,000,000-
 1,000,000-3,000,000—
 700,000-1  million	
 400,000-700,000	
 100,000-400,000	
          Category
                 1
                 2
                 3
                 4
                 5
                                                      Category
                     	     6
                     	     7
                     	     8

  Nonurban stations are classified according to the following
geographic and land-use categories: Atlantic coast, Great Lakes
coast,  Gulf coast,  Pacific  coast,  desert,  farmland, forest,  or
mountain.  The height of the air sampler above mean sea level
is also given  for each station.   Area  designations are not al-
ways clear  cut;  for  example, a mountain site may also be  a
forested area.
  A few  of the stations  are  designated by an asterisk.  This
indicates  that, while  the  station may have been  a part of the
Network,  no values are given because data were not sufficient
to meet the criteria in part 2.

                                PART  4—ANALYTICAL  METHODS
 The analytical methods described in this section of the

 report are those used  in the laboratories of  the Divi-
 sion of Air Pollution for the  analysis of suspended par-

 ticulate  samples.


 SAMPLES—COLLECTION AND PREPARATION

 FOR  ANALYSIS

 Collection

   Samples are collected for a 24-hour period on weighed 8- by 10-inch
 flash-fired, glass-fiber filters on the high-volume sampler.


 Weighing of Samples

   After collection, the sample is equilibrated at 75° F.  and 50 percent
 relative humidity for approximately 16 hours or overnight.  This insures
 that all samples  are brought to the same degree of dryness before being
 weighed.  Immediately  after removal  from the  equilibration chamber,
 samples are weighed, usually to the nearest milligram.


 Aliquotting of Samples  for  Analysis

   The analyses to be performed determine the subdivision of the sample.
 The filter is accurately cut into halves  or quarters by means of a template
 designed for  this purpose.  Smaller aliquots are removed by  means of a
 circular  steel  cutting die.  Since dies are available  in a  wide range
 of diameters, aliquots may be cut to  represent different percentages of
 the sample.
    Radioactivity.—Gross  /3-radioactivity  is determined on  the intact
 sample in  a large counting chamber  that accepts the flat 8- by 10-inch
 filter.
    Organic Materials.—Half of the sample is used for extraction of  the
 benzene-soluble organic pollutants.  Under certain conditions the whole
 filter may be used; when  this is done no other analyses are possible.
   IVonmetals.—Two circles 1% inch in diameter are cut from half of
 the sample.  Each circle  represents 4 percent of the sample.
   Metals.—The  portion  of the sample  remaining after six  1% inch
                        circles have been removed from a half sample is used for the spectro-
                        graphic determination  of metals.  This remainder, which  is equal to 26
                        percent of the sample, is  representative of the  whole sample.  If neces-
                        sary, a smaller portion of  the sample may be used for this measurement.
                           Quarterly Composites.—Quarterly composite samples are obtained
                        by combining portions of  all samples collected  during a quarter.  Sam-
                        ple aliquots should  be equivalent in terms of  the  volume of air repre-
                        sented by an aliquot.  For example,  a 4 percent aliquot removed from
                        a 2,000 m.3 sample would represent 80 m.3 of air.   To obtain an equivalent
                        aliquot from a 2,500 m.3 sample, a 3.2 percent  portion would be  taken;
                        for a 1,600 m.J sample,  a 5 percent aliquot would be removed.  To obtain
                        the various aliquots  a  4 percent circle can  be  cut into wedges, each of
                        which represents a fraction of a percent;  thereby it  is possible to secure
                        equivalent portions for compositing.  The composites are analyzed in the
                        same manner as the other samples.

                        ^-RADIOACTIVITY
                          The gross beta activity of the weighed sample  is measured on the entire
                        8- by 10-inch filter.  The  samples are  counted  after they  are 2 days old
                        to allow decay  of the natural alpha  and its associated beta-gamma ac-
                        tivity.  The samples may  be recounted after 4 to 7 days to establish the
                        decay in terms  of apparent  half-life of the  radioactive materials.  Com-
                        puted values are based on  these initial measurements in combination with
                        such additional  factors as  self-absorption, counting  efficiency, the  volume
                        of air sampled, and  the weight of particulates collected.  The computed
                        values are  given as  gross /3-radioactivity, in picocuries per cubic meter
                        of air on the date of sample  collection, and decay rate, expressed as half-
                        life beginning on the date of the first count.

                        INSTRUMENT

                          The counting  apparatus consists of a proportional gas  flow counting
                        chamber and preamplifier (Nuclear Measurements Corporation Model
                        PCC-12)  having a  thin  (0.9  mg./cm.=)  metal-coated  plastic  window
                        (Mylar),  a  conventional sealer  (Nuclear-Chicago Model  No.  181A
                        Decade), and a timer (Nuclear-Chicago  Dual  Timer Model Tl).  The
                        piston of the counter chamber is replaced with a steel plate, covered with
                        aluminum foil for ease of  decontamination.  The sample is placed on the
                        plate, 5 mm. below the thin window.

   Calibrations for Determining the Plateau and Instrument Per-
formance.—A sample of uranium  oxide placed on  a  2-inch diameter
stainless-steel  planchet, covered with  7 mg./cm.2  of  aluminum foil  to
shield out alpha activity, is used as a secondary standard for determining
the plateau and making daily calibrations.  These calibrations are made
three times daily for assurance that the instrument is performing properly.
Including a background of 500 counts per minute (cpm), the  activity
of the standard is 10,400 counts per minute.  Two materials are  used  as
primary  standards  for  determining  counter efficiency of internal  and
thin-window proportional counters: (1)  sources of radium D -f- E, plated
on stainless steel and covered  with 7 mg./cm.2 of aluminum foil, and (2)
standard solutions  of  thallium-204,  obtained from  the National Bureau
of Standards and deposited in counting pans.
   Initial Determination Of The Counter Efficiency.—A thin source
of thallium-204 having an area  of 18.1 cm.2 was counted in an internal
proportional counter having a geometry factor of 0.50 and a backscatter
factor of 1.31 or an overall efficiency of 0.655 cpm per disintegrations per
minute  (dpm).  The same source  centered 5 mm. below  the thin window
(7.5-inch  diameter)  counted 86  percent  of  the  internal proportional
counting rate,  i.e., 0.86 X 0.655, or 0.563 cpm per  dpm.
   A point  source of thallium-204  (2-mm. diameter) was counted at dif-
ferent radial positions, directly  under  the center of the window and out
to beyond the  periphery of the  window in four directions.  The plotted
results of these four sets of data indicated excellent  agreement for a given
radial  distance but a  diminution  of the counting rate as the  source ap-
proached the window periphery.
   The results  of these tests show that the effective counting area is only
41.9 square inches,  whereas the  total sample area is 63.0 squares inches.
Thus, the ratio of the effective counting area to the total sample area is
41.9/63.0, or 0.665.
   Filter Absorption and   Self-Absorption.—Filter  absorption  was
estimated from concurrent collections of air  particulates on glass-fiber
filters and  membrane  filters  with  equal filtering rates.   The  membrane
filters were ignited  to remove  the  possibility  of filter  absorption; the
glass-fiber filters were treated with conducting fluid and air-dried before
both types of  samples were counted in  an internal  proportional counter.
The percentages  of membrane filter activity recovered on the glass-fiber
filters ranged  from  88.7 to 92.0 percent, or an average of 90.3 percent.
   Because  of  the absorption  of radiation by the sample solids on the
filter, a self-absorption correction is required. The self-absorption correc-
tion factors are as follows: 1.04  for 0 to 0.6 gm.  samples, 1.12 for  0.6
to 1.0 gm. samples, 1.22 for 1.0 to  1.6 gm.  samples, and 1.36 for 1.6 to 2.4
gm. samples.

Counting  Procedure

   The chamber is preflushed at high rate with P-10 gas for about 1  hour.
Proper  flushing is ascertained by counting the background and a second-
ary standard  to  determine whether these have  changed from the day
before.   Low  background  or  standard counts indicate insufficient flush-
ing; high background counts indicate contamination.   Very little trouble
due to  contamination has been experienced,  even though some of  the
samples appear to contain loose dust. The flushing  procedure  is repeated
at the end of the day or when all samples for the day have been counted.
   The filter is placed on the steel plate, which is then placed in the proper
position in the chamber.   Two  counts of 2 minutes each are taken.  If
the two counts do not agree,  a third count is made.  A similar count is
made after a lapse of 4 to 7 days.

Calculation of  Radioactivity

Determining  the  Radioactivity of the Sample

   1. The average gross counts per minute are obtained  from the results
of the 2-minute counts.
   2. The cpm  of background  is subtracted from the  average cpm of the
sample  to find the average net cpm.
   3. Corrections  are  made for counting efficiency  and filter  absorption.
Dpm (disintegrations  per minute) =net cpmX 1/.563X1/.655X 1/.903.
l/.563=correction for efficiency=l/.86Xl/.655.
l/.665=effective counting area correction.
l/.903=filter absorption factor.
  4.  Dpm are converted to picocuries.
dpm/2.22=pc(picocuries).
  5.  Corrections are made for volume of air sampled.
pc/V=pc/m.3 (uncorrected).
V=volume of air sampled in cubic meters.
  6.  Corrections are made for self-absorption of sample.
pc/m.3  (uncorrected) XFs=pc/m.3 (corrected).
Fs=self-absorption factor.

Determining the Average Half-life of Radioactive Isotopes in the
     Sample

  1.  Net cpm  is plotted  against counting date on  semi-log paper.  The
count is plotted on the log scale and the days between the counts on the
linear scale.
  2.  A straight line is drawn through the two points.
  3.  The point on the line where the net cpm is one-half that found when
the sample was first counted is determined.
  4.  A vertical line is dropped  from the point to  the  base.  The number
of days  from the date of the first count to this point is the average half-life
of the radioactive isotopes present in the  sample.
   Determining  Radioactivity on  Date  of  Sample  Collection.—
Samples having an apparent half-life of less than 10 days are corrected
for decay to the date of collection by extrapolating a plot of the  decay
results on log-log paper.   This  extrapolation is based on  the assumption
that  the  Way-Wigner formula (ATk=constant)  is  valid and on an
assumed date  of  bomb-debris  formation, which provides values  for k
between 1.1 and 1.2 (log-log plots of decay data of high-level bomb debris
usually  follow  the theoretical negative exponential decay rate of 1.2 rather
closely,  while low-level activity or activity 10 or more days old have  decay
slopes that are less  than 1.2 but rarely less than 1.0).   If the half-life
is greater than 10 days, the results of the two counts are  plotted  on semi-
log paper and the activity of the sample is determined by extrapolating
back to the date of collection.
   Reliability of  Radioactivity Data.—The reliability of radioactivity
data is  somewhat variable since it  depends upon many  factors, such as
the age  of the bomb debris when first counted, the  number of days from
collection to  date of first count,  and  the  counting error, which  is a
function of the counting  rate.  For bomb debris less than 5 days old and
for relatively high  activity it is  possible  that the extrapolated value  could
be off by a factor of 2 because fractional parts of a day are not considered.
For materials having an age of 10 days or more, the determination should
be within 10  percent of the correct value.  For low activity in the  order
of 10 days or more, the determination should be within 10 percent of the
correct  value.  For low activity in the order of 1,000 cpm per sample, the
raw  counting  error at  the 95 percent confidence  level may be estimated
to be 1.96/2  (1,500 plus 500)1/2 =44 cpm,  or 4.4 percent; the error for
a sample with  a count of  500 cpm (or equal to the background) would be
1.96/2 (1,000 plus 500)1/! =38 cpm, or 7.6 percent.

ORGANIC  MATERIALS

Selection of  Solvent

  Several solvents have  been  used for  removing organic materials  from
air particulate samples.   The choice of solvent must be based upon the
interest of the individual worker.  Extraction with  acetone will  result in
the removal of more organic matter from  the sample  than  would the
extraction with benzene,  ethyl ether, chloroform, etc., but the extracted
material will  not  completely redissolve in  any solvent.  Benzene and
cyclohexane extracts redissolve  readily  and are well suited for infrared
examination.   Polycyclic  compounds are effectively removed by  benzene
or cyclohexane extraction.  Chloroform,  a  very  satisfactory solvent, re-
moves only slightly less material than does acetone.
  From 1953 through June,  1955, acetone was used to remove the organic
materials  from all samples.  The major interest during that time was in
the determination of atmospheric protein levels.  Use  of acetone as  a

-------
                                                                                                                                            213
 solvent resulted  in  the removal  of maximum amounts of  nonprotein
materials  which  could have  interfered with the  protein measurement.
 The extracts  obtained by this  procedure were difficult to handle  when
 used  for  further  chemical  studies, and  also contained considerable in-
 organic matter.  Therefore, the use of this solvent was discontinued at
 the end of the protein study.  Since July 1, 1955,  all samples have been
 extracted with redistilled benzene, which, while  it does  not  remove all
 of the organic material present  in the sample, does provide a  more useful
 product for further analyses.

 Extraction Procedure

   1. The  sample is folded into a bundle to prevent  loss of material during
 the extraction procedure and  to allow it to be easily introduced into the
 extractor.  The bundle is tied  with fine copper wire.
   *2.  The sample  is  placed  in a  Soxhlet  extractor and  extracted  with
 benzene  for 6 to 8 hours.  This extraction will remove over  95 percent
 of the soluble organic materials from the sample.   At the  end  of  the
 extraction period,  the  solution is concentrated in the extraction flask to  a
 small volume  (5 ml.).  This  can be done by removing the solvent from
 the extractor instead of allowing it to return to the  extraction  flask.
   *3. The concentrated extract is filtered  through  a medium-porosity
 Corning fritted glass filter into  a weighed test tube or flask by means of
 a Fisher Filtrator  or similar apparatus.  The original container and filter
 are  washed at  least  twice with small amounts  of chloroform.  Small
 volumes of chloroform efficiently remove the organic materials and prevent
 accumulation  in the filter of organic matter, which may clog  the pores of
 the  filter.  This procedure  allows  the filtration  of  several  samples in
 sequence  with no chance of contamination.
   4. The remainder of the solvent is removed by heating in an oven main-
 tained slightly below the boiling point of the solvent (60° F).  All electri-
 cal controls of the oven must  be outside the oven to prevent the possibility
 of an explosion,  which might result  from the  sparking  of  the  con-
 trols.  The  solvent may also be removed  "in vac" but boiling may occur,
 with resulting loss of material.
   5. The sample is weighed after the last of the  solvent has been  removed.
 If desired, the samples may be reheated until they reach a constant weight.
 The concentration of organic matter is then computed.

 Analysis

   Examination by infrared spectroscopy of the crude organic materials
 obtained  by the above procedure often provides useful information.  Since
 most extracts are complex  mixtures of a large number of organic com-
 pounds, infrared spectroscopy seldom gives  information on the  presence
 of individual  compounds but gross  differences between samples can be
 detected.   In  at  least one instance a specific compound  (caffeine)  was
 identified by this technique.
   The crude  organic materials  obtained  by  extraction with benzene may
 be separated into water-soluble, basic, weakly acidic, strongly acidic, neu-
 tral, and  water-ether insoluble fractions by the following procedure:
       1.  The  sample  to be fractionated is weighed in  a small flask, then
     loosened  from the flask by  the addition  of a small amount of ethanol
     or chloroform.  As much  of the  loosened crude composite sample
     as possible is  dissolved  in ethyl ether and the solution  filtered through
     a tared fritted glass funnel.  The residue on the funnel  and  that
     remaining in the flask are  washed with water.  The flask and the
     funnel, both   containing some  insoluble  material,  are  dried  and
     weighed.   This gives the total weight of water-ether-insolubles.
       2.  The  filtrate  (from 1). a  two-phase system, is transferred to  a
     separatory funnel.  The  water layer is  removed and evaporated to
     dryness.  The residue represents the total water-soluble fraction.
       3.  The  ether layer (from 2)  is extracted  with  an equal volume
     of 5  percent hydrochloric acid.   The lower layer (acid  solution) is
     transferred  to  another  separatory  funnel  and  the  ether  solution
     is saved for step 5.
       4.  The  acid extract (from 3)  is made alkaline with strong sodium
     hydroxide solution, and  extracted with an  equal volume  of ethyl
     ether.  The ether layer is drawn off and dried with anhydrous sodium
     sulfate.  The  sodium sulfate is removed by filtering, and the flask  and
  •Steps 2 and 3 should be accomplished in a hood.
    salt are rinsed with several small portions of ether.  The ether solu-
    tion is evaporated  to dryness.  The residue  is  the  basic  (amine)
    group.
      5. The ether layer (from 3)  is extracted with an equal volume of 5
    percent sodium hydroxide solution.  The lower layer is transferred
    to another separatory funnel and saved for  step 7.
      6. The ether layer (from 5)  is drawn off and dried with anhydrous
    sodium sulfate.  The salt is removed by filtering, and  rinsing with
    several portions of dry ether. The ether solution is evaporated to dry-
    ness.  The  residue  is the  neutral group.
      7. The alkaline solution (from 5) is saturated with  carbon dioxide
    to  give a pH of 8 and extracted with  ethyl ether.  The lower layer
    is  transferred  to another separatory funnel and saved for step  8,
    The ether solution is dried with anhydrous sodium sulfate.   The salt
    is removed by filtering.  The ether solution is  evaporated to dryness.
    The residue is the weak acid fraction.
      8. The solution (from  7)  is acidified to pH 3 with concentrated
    hydrochloric acid and extracted with ethyl  ether.  The lower layer
    is discarded.  The ether  layer is dried over anhydrous sodium sul-
    fate.   The salt is remove by filtering, and the ether by evaporation.
    The residue is  the  strong acid group.
  The neutral group may be further divided  by  column chromatography
on silica gel into aliphatic, aromatic, and oxygenated neutral compounds.
      1. A chromatographic  tube,  20  mm. in diameter, is  packed to a
    height of 10 cm.  with 200-mesh silica  gel.  The  neutral group, dis-
    solved in a  small  volume of  ether or  chloroform,  is transferred  to
    a small amount of silica  gel, the solvent  is  removed,  then the silica
    gel is  transferred to the top of the column.
      2. The  column is eluted initially with 85 ml. of 2,2,4-trimethyl-
    pentane  (isooctane) and  then with a similar volume of  benzene.
    Finally it is flushed with  a 1: 1 mixture of chloroform and methanol.
    The isooctane eluate contains the aliphatic  fraction,  the  benzene
    eluate the  aromatic fraction, and the chloroform-methanol eluate the
    oxygenated neutral  fraction.

METALS—SPECTROGRAPHIC  METHOD

   Standardization.—A stock solution of the following metals,  with the
concentrations indicated, is prepared: Be, Bi, Cd, Co, 1 /igm/0.05 ml.; Sb,
Cr, 2 /igm/0.05 ml.; Mo, Ti, 4 /igm/0.05 ml.;  Ni, V, Sn, 8 /igm/0.05 ml.;
Mn, 20  /igm/0.05 ml.; Cu, Fe, Pb, 100 fjgm/0.05 ml.; Zn, 200 /igm/0.05 ml.
Salts  used should be ACS grade or better.  "Working standard solutions
are made  by  diluting the stock solution to  give  concentrations Y2, %,
%      1/1024 of the original. One stronger standard is made by dou-
bling the quantity on the electrode.
  A nitric acid  extract  of the glass filter (63 sq.  in. of filter = 40 ml.
acid extract) is added directly to the electrodes in  order to duplicate the
conditions  obtained in the paniculate sample solution.  This compensates
for  the  acid  soluble  material  present in the  glass  filter, some of  which
could interfere in the metal analysis.  This procedure eliminates the need
for  making separate corrections for metals  present in the filter.
  Three replicate standard plates   are made as follows.  Electrodes  of
high-purity graphite (V crater with center post) are warmed 10 minutes
in an oven at about 80° C.  The crater  portion is  briefly immersed into
a hot 20 percent solution of  paraffin  in redistilled benzene,  then oven-
dried for a few  minutes.  The crater is then filled Vs full  with a LiCl-
graphite mixture (1 part LiCl and 2l/2 parts graphite), 0.05 ml.  of the
glass filter extract  (equal to  1/800 of the filter)  is transferred  to the
electrode, and 1 drop of methanol added to distribute the solution evenly.
The  electrodes  are  partially  dried in the oven,  then 0.05 ml. of the
working standard is  pipetted   (0.10 ml. for the  stronger standard), and
one drop of methanol is added. The  electrode is  dried at 80° C. then
heated at 105° C. for 1 hour.
  The loaded  electrodes are arced, as  the anode, 30 seconds on a Baird
3-meter-grating spectrograph at about  7 d.c.  amperes.  Prior to arcing,
the current is set at 8.25 amperes closed  circuit and not adjusted further
during the arcing period.  Gap is maintained at 3 mm., slit 6 mm. X 25 ji.
Pointed counter  electrodes are sharpened in a pencil sharpener.
  A single-step  sector, passing one-eighth of the uninterrupted beam, is
interposed between the slit and the lens.  Eastman 103-0 plates are used,

-------

and the first order of the region 2170 A° to 3590 A° recorded.  The plates
are processed by  standard  procedures (3 minutes D-19, 68°  F. water
rinse;  10 minutes in Kodak acid fix, and 25 minutes wash).  Line in-
tensity is measured with an NSL Spec. Reader.
  The following analysis lines are used: Cd 2288.0 A", Be 2348.6  A", Fe
2457.6 A", Pb 2663.2 A",  Cr 2677.2 A", Cu 2824.4 A°  and 3274.0  A", Sn
2840.0 A", Sb  2877.9 A8, Mn 2933.1 A°, Ni 3003.6 A",  Bi 3067.7 A°,
Mo 3170.3 A", V 3183.4 A°, Ti 3199.9 A", Zn 3345.0 A", and Co 3453.5 A".
  Calibration curves for each metal are plotted as ratio of percent trans-
mittance of line  plus background to  percent transmittance of adjacent
background versus micrograms of metal on the electrode on log-log graph
paper.  Data from the curves are consolidated in chart form.

Analysis

  To permit more complete  removal  of inorganic materials  than  is pos-
sible by simple acid extraction, samples (26  percent of the original)  are
first muffled at 500°  C. for 1 hour to burn off organic matter. Then, two
extractions with 40  ml. portions of  1: 1 redistilled nitric acid are made
at slightly below the boiling point for 1 hour.  After  the resulting solu-
tions are filtered through Whatman No. 42 filter paper, they are evaporated
to 3 to 4 ml. and then made up  to 10.4 ml.  (0.05 ml. of  this solution is
equivalent to 1/800 of the sample).
  Electrodes (preparation described above,  except the addition of glass-
filter extract is omitted)  are loaded  with 0.05 ml. of sample  solution.

Extraction  of Water-Soluble  Materials

  An 8 percent aliquot of the  sample is placed in a 125 ml. flask, and 50 ml.
of distilled water  added.  The mixture is refluxed for 90 minutes, cooled
and filtered through Whatman No. 1 paper.  The extraction is repeated
with  10-15 ml. water and mixture is heated only a few  minutes with-
out a  condenser.  The solution is filtered through the same filter;  the
flask and the filter are washed until  the total volume of nitrate  is 80 ml.
The filtrate is mixed thoroughly and  stored in a  clean, rubber-stoppered
bottle.
  This solution may be used for the determination of nitrates,  sulfates, and
pH.  Each ml.  of  the solution is equivalent to 0.1  percent of the sample.
  Note:  A 4  percent aliquot of  the  sample may be  extracted,  giving
a final volume of 40 ml.

Determination of Sulfates

Reagents

  1.  10 A' hydrochloric acid.
     Eighty ml. of concentrated acid  is diluted to 100 ml. with distilled
     water.
  2.  Glycerine—alcohol solution.
     One volume  of  glycerine is mixed with two volumes  of 95 percent
     ethanoL
  3.  Barium chloride crystals.
     High-quality 20-30 mesh crystals are used.
  4.  Stock standard solution (1000 /ig S0»/ml.).
     1.48 grams of anhydrous  sodium  sulfate is dissolved in distilled water
    and diluted to 1 liter.
  5. Working standard solution (100 /j.g SOi/ml.).
    Ten ml. of stock standard is diluted  to  100 ml. with distilled water.
    This solution should be prepared daily.
 Analysis
   Twenty ml. of the  water extract (2 percent)  of the sample is pipetted
 into a clean, dry cuvette;  1 ml. 10 N hydrochloric acid and  4 ml. of the
 glycerine-alcohol solution  are added and the solution mixed well.  The
 optical density  is read  at 500  m/j.  against  the  blank.   This reading is
 subtracted from the final reading as a correction for unmatched cuvettes
 and impurities in the sample.  Approximately 0.25g  of  barium chloride
 crystals are added and mixed until dissolved.  After  the mixture stands
 for 40 minutes, the optical density is read at 500 m/i  against the reagent
 blank.  Any spectrophotometer that accommodates cuvettes with a light
 path of 25 or 50 mm.  should be satisfactory.
   The sulfate content of the 20-ml.  sample is determined by referring to
 the calibration curve.

should be a straight line.

Nitrates

Reagents
  1. Xylenol reagent.
     Five ml.  of  2,4 xylenol is mixed with 500 ml. of glacial acetic acid.
  2. Sulfuric acid solution (85 percent).
     With care, 480 ml. of concentrated  sulfuric acid is added  to 117 ml.
     water, mixed well, and cooled during the addition.
  3. Sodium hydroxide solution (0.4 N).
     Sixteen  g of sodium hydroxide is  dissolved in water,  diluted to 1
     liter, and stored in a polyethylene bottle.
  4. Stock standard  solution  (100 /jg  NO^/ml.).   0.163  g  potassium
     nitrate is dissolved in water  and diluted to  1  liter.
  5. Working standard solution (20 pg NO^/ml.).
     Five ml.  of stock standard is pipetted into a 25-ml. volumetric flask,
     diluted to the mark, and mixed.
Analysis of  Sample
  A 5-ml. aliquot of  the water extract  (0.5 percent) of the sample  is
pipetted  into  a 25-mm test tube;  15 ml. of  the 85 percent  sulfuric acid
is added;  the solution is mixed  and allowed to cool.   One ml.  of the
xylenol reagent  is  added; the solution  is mixed, heated in a 60° water
bath for  30 minutes, and cooled. The contents of the tube are transferred
to a 250-ml. separatory funnel, the tube rinsed with distilled water, and
according to  a prearranged mark on the funnel, diluted to approximately
80  ml.   Ten  ml.  of toluene  is added to the separatory  funnel  and the
mixture  shaken  for 2  minutes.  (A mechanical shaker  gives  more uni-
form  results.)  After  15 minutes, the  lower  layer is run  off and  dis-
carded.  The  toluene is  gently shaken in the separatory funnel with 20
to 25 ml. of water and allowed to settle a few minutes.   The lower layer
is completely run off and discarded.  Ten ml. of 0.4 N sodium hydroxide
solution  is added.  The  mixture  is  shaken  for  5 minutes, allowed  to
stand until the lower  layer becomes clear, then the lower layer  filtered
through  Whatman  No. 1 paper into a  clean, dry cuvette.  The  optical
density of the solution at 435 m^i is read against  a  reagent blank pre-

-------
pared in the same manner.  All cuvettes are emptied, rinsed well, filled
with distilled water, and optical densities read against the reagent blank
cuvette.  The optical density of the sample is corrected for the  optical
density of the cuvette.  The standard curve is used to find the amount of
nitrate in the sample aliquot analyzed.

            PART   5—EXPLANATION  OF  STATISTICAL  TERMS
CUMULATIVE   FREQUENCY   DISTRI-
BUTION

  The cumulative frequency distribution is presented in terms
of the  10th. 20th, .  .  . 90th percentiles.  The percentiles de-
fine the concentration of a pollutant such that the corresponding
percent of the total samples had concentrations less  than  or
equal to (i.e., not greater than )  the stated amount.  As an ex-
ample.  consider the  cumulative  frequency distribution for  all
urban stations for 1957 I table 2.1 1 .  The entry in the 90 percent
column is 238; that is to say. for 90 percent of the 2.360 samples
collected, or 2.124. the concentration of suspended  particulates
did not exceed 238 /ig/m.3   Conversely, for 10 percent, or 236
samples, the concentration  of suspended particulates was 238
fig m.3 or more.
  Other percentiles  can  be interpreted in a similar  fashion.
The 50 percentile is also known as the median of a distribution.

ARITHMETIC  MEAN

  In the  presentation  of numerical data one seeks to find a
value that is most representative of the entire set of data.  Such
a value is referred to as a  measure of central tendency.  The
equation for computing the most commonly used  measure  of
central tendency, the arithmetic mean (average I , is
where

   X=the arithmetic mean.

   N=ihe number of measurements.

GEOMETRIC  MEAN

  If the  distribution  of  a  set of numbers is  approximately
normal (the familiar bell-shaped  curve), the arithmetic mean
is an appropriate measure of central tendency.  Studies of the
distribution of measurements of particulate air pollutants tend
to indicate, however, that  a more suitable frequency function is
that of the log-normal distribution  (3, 12).  For this class of
distributions, the  logarithms of  the actual measurements are
approximately normally distributed.  The  measure of central
                                                             tendency most appropriate for the log-normal distribution is the

  A brief review of the properties of the standard deviation of
a normal distribution will help to better understand the stand-
ard geometric deviation.  The normal curve is symmetrical, and
the mean  and  median (i.e., the 50th percentile) coincide  (fig.
5.1).  If the area under the normal curve is  assumed to be
unity, then it can be shown that 0.6827 of this area is contained
in the interval X±v.  It can be further shown that 0.8413 of
the area lies to the left of X+a.  Likewise for the log-normal
distribution 0.6827 of the area under the curve lies in the
interval Xg/vg  to Xgag, and 0.8413 of  the area lies to the left
of XgUg.
  A graphic presentation of the log-normal distribution  can
be easily constructed, since the cumulative frequency  distribu-
tion is linear when plotted on  logarithmic probability graph
paper.  One can plot several points (e.g., the  percentiles) of
the cumulative frequency distribution or, more  easily, plot the
geometric mean value (Xg) on the 50 percent ordinate and the
value XgVg on the 84.13 percent  ordinate and fit a  straight
line to the set of  points.  As an example,  the cumulative  fre-
quency distribution  of  suspended particulates for all urban
stations for 1960 is plotted, by the two techniques just described
(fig. 5.2).  First, the percentiles of the cumulative frequency
distribution are plotted (table 2.1).  Next, the geometric mean
of 99 ng/m? is plotted on the 50 percent ordinate and the value
176  fug/m3 (1^=99X1.78) is plotted on the 84.13 percent
ordinate.   The same straight line fits both sets of points.
