PREFACE
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

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.
Region 1—New England: Connecticut, Maine, Massachu-
setts, New Hampshire, Rhode Island, Vermont.

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

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

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,
-------
214
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.
Arcing conditions, plate processing, and densitometry are the same as
standard plate conditions. By use of the numerical value of the line plus
background to background ratio, amounts of each metal on the electrode
are obtained by reference to the chart.

NONMETALS
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.

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

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
geometric mean given by

log Xj=the sum of the logarithms of the measurements.
log2 Xt=the sum of squares of logarithms of measure-
ments.
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.

CORRELATION COEFFICIENT
The correlation coefficient is a measure of the linear depend-
ence between two variables. By mathematical definition, the
correlation coefficient can vary in magnitude from — 1 to +1.
Two variables that tend toward linear dependency will have
a correlation near — 1 or +1, while independent variables will
have a correlation near zero. The equation of the correlation
coefficient is given by:

r= i-1 ' '~ 1-1 * <-l
