PREFACE
The Air Quality and Emission Data Program of the National Air Pollution
Control Administration, with the assistance and cooperation of state and local
agencies, carries on a variety of air sampling activities to obtain information
about air quality in the United States. This report summarizes data on partic-
ulate and gaseous pollutants gathered during 1966 at the cooperating stations of
the various National Air Surveillance Networks and similar data from independent
state and local sampling networks that have contributed their results to the central
air quality data bank operated by the Air Quality and Emission Data Program. The
data on chemical components of the particulate matter in the air are generally for
1965, because of the necessary time lag in laboratory analysis, or for earlier
years in cases in which previously gathered samples held in reserve have been
retrospectively analyzed.
This publication is one of a series of annual reports designed to make air
quality data available widely as soon as practicable. For this reason, thorough
analysis and interpretation of the data are not attempted in these reports, but
will be published periodically in separate reports.

ACKNOWLEDGMENTS
The data reported in this publication could not have been gathered without
the generous cooperation of the many state and local air pollution control agencies
in the operation of the NASN sampling stations. The National Air Pollution Control
Administration offers sincere thanks to these organizations and to their employees.
Gratitude is also due the agencies that have contributed their own data to
the National Center's air quality data bank for use in this and other reports and
studies. Their efforts make possible a greatly increased national knowledge of
air quality.

AIR QUALITY DATA, 1966
INTRODUCTION
Today's National Air Surveillance Networks have developed from the Public
Health Service's first air pollution sampling effort. In 1953, the Public Health
Service's Division of Sanitary Engineering Services in cooperation with various
state and local agencies began sampling for suspended particulate matter with
high-volume air samplers in 17 cities. By 1956, this sampling program had ex-
panded to encompass 66 communities, and a national need and desire to have a
larger, truly national air quality sampling effort had become apparent. As a re-
sult, in January, 1957, the National Air Sampling Network was established to
routinely monitor suspended particulate levels in urban and nonurban America.
The scope of sampling was expanded to some 185 urban and 48 nonurban stations,
of which about 100 of the urban and all of the nonurban stations •were scheduled to
operate each year. Urban stations operating each year have been increased to
about 150, and nonurban stations have been reduced to a representative group of 30.
Since 1957, network operations have expanded also in the number and types
of pollutants measured. The constituent pollutants measured in high-volume
samplers are listed in Tables 1 and 2. Techniques for sampling the respirable
dust fraction are being developed. During 1959 and I960, limited 24-hour bubbler
sampling for the gases NO£ and SO2 began at a few stations. Operations are being
expanded to sample for aldehydes, ammonia, and total oxidant, in addition to the
original two gases, and the number of stations has increased to 50. The con-
tinuous Air Monitoring Project, begun in 1962, provides detailed information in
gaseous pollutants in six cities where continuous instruments record levels of
six pollutants (carbon monoxide, hydrocarbons, nitric oxide, nitrogen dioxide,
oxidants, and sulfur dioxide) every 5 minutes.
In 1966, a 25-station lead peroxide candle network began routine operation
to provide sulfation rate information and to permit comparative studies of this
traditional, inexpensive SOX monitoring method.
With the reorganization of the Public Health Service on January 1, 1967,
these network sampling operations collectively were designated the National Air
Surveillance Networks and 'were incorporated in the Air Quality and Emission
Data Program of the National Center for Air Pollution Control (NCAPC) in the
Bureau of Disease Prevention and Environmental Control of the Public Health
Service. In July 1968, the National Center was redesignated the National Air
Pollution Control Administration (NAPCA) under the Consumer Protection and
Environmental Health Service. Although the Air Quality and Emission Data
-------
Program and other NAPCA programs conduct numerous special studies involving
air sampling, the majority of the present DREW air quality surveillance sampling
is conducted by the four National Air Surveillance Networks: the suspended partic^
ulate, or "Hi-Vol", network; the gas sampling network; the Continuous Air
Monitoring Program; and the lead candle network.
These four networks are operated in cooperation with appropriate state or
local agencies. The Air Quality and Emission Data Program generally provides
equipment, supplies, and laboratory analytical services, and the cooperating
agency provides the sampling site and the manpower. In addition to assisting the
DREW sampling program, many state and local air pollution control agencies
operate their own air quality monitoring networks.
-------
SUMMARY OF AIR QUALITY MEASUREMENTS
This report presents summaries and analyses in addition to basic data
tabulations. This section includes national summaries of pollutant levels, and
figures illustrating variations in the levels of gaseous pollutants.
NATIONAL SUMMARIES
Table 1 summarizes data on suspended particulates and on SO2 and NC>2,
the two gases routinely measured at the 24-hour bubbler stations. Data on
ammonia sampling, introduced in"i 966, are insufficient to warrant a network
average, but ammonia sampling data for individual stations are summarized in
Table 83. Table 1 reflects in several ways the recent expansion of analytical
resources. The averages for several of the particulate components represent
for the first time the analysis of samples from all of the cooperating NASN
stations. Expanded laboratory capacity also has permitted for the first time the
extensive analysis of nonurban samples and the analysis for benzo(a)pyrene, an
organic carcinogen.
As explained later, nonurban samples for metals analysis are extracted dif-
ferently from urban samples. This results in different sensitivities in the urban
and nonurban measurements and makes the usual data summary unsatisfactory

CAMP DATA ON GASEOUS POLLUTANTS
This publication, including much more detailed CAMP data than has been
presented previously, reflects a shift away from the extensive separate publi-
cation of CAMP data. Tabulations of hourly average CAMP data for 1966 are avail-
able separately, and interpretive discussion of the data will be separately publish-
ed periodically.
Since the six CAMP stations in operation are too few to represent a national
average, CAMP data are not included in Table 1. Annual averages for the individ-
ual CAMP stations for 1962 through 1966 are summarized in Table 4.

Average not calculated because of insufficient or poorly distributed data.
-------
Since the formation of photochemical oxidant is so directly dependent on
sunlight, averages that include levels during nighttime hours may appear decep-
tively low. For this reason, Table 5 lists for each city the number of days in
•which at least one hourly average total oxidant concentration exceeded 0. 05, 0. 10,
and 0. 15 ppm. This summary gives some indication of the frequency of photo-
chemical smog. Total oxidant data are not reported for 1962 and 1963 because
of a sulfur dioxide interference in the detection system in use during those years.
Previously published summaries of 1964 and 1965 oxidant data are slightly dif-
ferent from the summaries in Table 5 because the summaries in this table exclude
any maximum hourly concentration not occurring between 11:00 a.m. and 5:00p.m,
and consider instead the highest hourly value occurring between those times.
Maxima occurring outside this 6-hour period probably represent not photochemi-
cal pollution, but isolated industrial emissions of oxidizing chemicals or the
oxidizing potential of nitrogen dioxide.

EMISSION INVENTORY OF SULFUR DIOXIDE
Figure 13, based on published data for 1962 through 1966, shows estimated
emissions of sulfur dioxide (in tons per square mile per year) for 69 Standard
Metropolitan Statistical Areas (SMSA).
The total emissions were arrived at by inventory of emissions throughout
the SMSA or by estimate from the consumption of sulfur-bearing fuels in the area.
Almost all of the SMSA's in the higher density categories are located east
of the Mississippi River and within a belt that stretches diagonally across the
country. Much of the nation's industrial activity is concentrated in this region,
where coal and fuel oils are the main sources of energy.

DATA TABLES
SUSPENDED PARTICULATES
Tables 6 through 9 present 1966 data on the concentration of suspended
particulate matter in the air. Data from urban sampling stations are presented
as frequency distributions, by state in Table 6 and by individual stations in
Table 7. Table 8 presents frequency distributions of suspended particulate data
from nonurban stations, and Table 9 presents abbreviated summaries of data from
stations for which a representative year's data were not available. The stations
indicated by asterisks are operated by state or local agencies that contribute to
the central air quality data bank.
The weight (or mass) of particulate matter per volume of air usually is
determined by drawing air through a pre-weighed filter with a high-volume, or
"Hi-Vol", air sampler, and then weighing the soiled filter. Precise laboratory
procedures, however, may differ from one laboratory to another. The following
procedure is used by the Air Quality and Emission Data Program for all sampling
conducted by the National Air Surveillance Networks.
Each city's "Hi-Vol" sampler is located in the central business-commercial
district at a site that is, as nearly as practical, comparable with the correspond-
ing sites in other cities. In such a location, measured concentrations tend to be
among the higher concentrations found in the city and, therefore, cannot be inter-
preted as the city-wide average. Contrasts between cities are considered valid
on a relative scale, however.
The "Hi-Vol" samplers, operate at 40 to 60 cubic feet per minute, collect
particulates from about 2200 cubic meters of air during the 24-hour sampling
period. The NASN stations are operated during 26 randomly selected days per
year. The filters used are 8- by 10-inch flash-fired glass fiber filters selected
for low and uniform background concentrations of those substances to be detected.
To eliminate any that have pinholes or other flaws that could affect air
flow, the filters are screened on a light table. Prior to weighing, they are
equilibrated for 24 hours at 75 °F and a relative humidity of 50 percent or less.
Since any crease in a filter can seriously affect the airflow, filters are weighed
with a balance that permits weighing without bending.
The filters are then distributed unfolded to the cooperating local agencies.
After sampling, the filters with the collected particulate matter inside are folded
in half and are returned to the laboratory. After a filter with the collected
particulates is again equilibrated for 24 hours at 75 °F and 50 percent or less
relative humidity, it is weighed to determine the amount of particulate matter
collected. The equilibration at low relative humidity prior to this weighing is
of crucial importance, since many of the compounds collected (ammonium sulfate
in particular) are quite hygroscopic. Figure 14 shows the effect of humidity on
the measured weights of soiled filters from three widely differing sampling
locations. The increase in weight at the higher humidities represents the amount
of atmospheric moisture collected by the particulate matter on the filters.

ORGANIC PARTICULATES
Tables 10 through 14 present 1966 data on the portion of suspended partic-
ulate matter that consists of organic chemical compounds. The concentrations
of benzene-soluble organic material from urban stations are summarized by
state in Table 10; data for individual urban and nonurban stations are presented
in Tables 11 and 12, respectively. All bejizene-s oluble organic concentrations
are determined from quarterly composite samples.
The numerous specific organic compounds that dissolve in benzene are
believed to include most of the man-made organic pollutants. Natural organic
particulates in the air, such as pollens and molds, generally are not soluble in'
benzene.
Benzene-soluble organics are determined by extraction of aliquots of the
samples with redistilled benzene in a Soxhlet* extractor for 6 to 8 hours. This
*Mention of a company or product name does not imply endorsement by the United
States Department of Health, Education, and Welfare.
28
-------
extraction removes more than 90 percent of the benzene-soluble organic materials
from the sample. After extraction, the solution is concentrated and is filtered
into a tared test tube. The benzene solvent is then evaporated at 60°C, and the
organic matter remaining is weighed.
Tables 13 and 14 present data on the concentration of benzo(a)pyrene in
the particulate matter from urban and nonurban stations, respectively. Benzo(a)-
pyrene, one of the many specific organic compounds included in the benzene-
soluble fraction, is of sufficient interest to -warrant separate determination be-
cause of its carcinogenic, i.e. cancer-causing, properties.
The benzo(a)pyrene analyses were conducted on three composite samples
for each station: a first-half (January-June) composite and quarterly composite
samples for the third and fourth quarters. The first-half composites are entered
in Tables 13 and 14 as identical values for the first and second quarters and
were weighted twice in the calculation of the annual averages.
The units used in reporting benzo(a)pyrene concentrations are different
from those used for other fractions of the particulate matter. Because it is
present in extremely small amounts, benzo(a)pyrene is reported in nanograms
(10~"grams) per cubic meter rather than in micrograms (10~"grams) per cubic
meter.
RADIOACTIVITY
Table 15 summarizes beta radioactivity measurements of particulate
samples gathered during 1966. The urban and nonurban data are summarized
together by state, since radioactive material is generally distributed from the
upper atmosphere over urban and rural areas alike. In 1967 the Air Quality and
Emission Data Program discontinued routine radioactivity monitoring of network
samples. This effort was conducted in cooperation with the National Center for
Radiological Health, which will continue to gather similar information through
its own sampling netv/ork.
NONMETALLIC INORGANIC PARTICULATES
Tables 16 through 21 present the results of chemical analyses of samples
for 1965 of three nonmetallic inorganic groups. Data on ammonium, nitrate,
and sulfate compounds in particulate samples from urban stations are presented
in frequency distribution format in Tables 16, 18, and 20, respectively, and
comparable data from nonurban stations in Tables 17, 19, and 21. For the first
time, the samples, including nonurban samples, from all NASN stations in a
given year have been analyzed.
Analyses for all three of the nonmetallic inorganics are conducted with
autoanalyzers on an aqueous extract of an 8. 3 percent aliquot of the particulate
sample. The sample aliquot is refluxed with 50 ml of distilled water in a 125-ml
flask, cooled and filtered, and then reextracted with 10 to 15 ml of water. In
filtration of this extract, the filter and flasks are washed to a total volume of
50 ml of filtrate, which is then mixed and used for the three analyses.
Ammonium ion in the filtrate is determined by reaction with sodium
phenolate and a commercial 5. 25 percent stabilized sodium hypochlorite solution
to produce a blue complex. The intensity of the color of this complex is measured
spectrophotometrically. at 425 millimicrons.
29
-------
Nitrate ion in the filtrate is reduced to nitrite by alkaline hydrazine (pH
about 11). Sulfanilamide is then added to form a diazo compound, which is
subsequently complexed with N-1-naphthylethylenediamine. The resulting com-
plex is measured spectrophotometrically at 535 millimicrons. This method offers
distinct advantages in avoiding interferences from other water-soluble compounds
found in atmospheric particulates.
Sulfate ion in the filtrate is determined by the methylthymol blue method
which is appropriate only with autoanalyzer techniques since the methylthymol
blue dye is oxidized by atmospheric oxygen. The filtrate is reacted with a re-
agent consisting of equal parts of methylthymol blue'dye and barium chloride,
kept at a pH of 2. 8 to prevent the formation of a chelate complex from the dye
and the barium. Any sulfate ion in the sample reacts with the barium, leaving
an excess of methylthymol blue"dye that is proportional to the amount of sulfate
present. The pH is then raised to 12. 4, at which point the barium not removed
by the sulfate forms a chelate complex with the methylthymol blue dye and the
excess dye turns yellow. The intensity of the yellow color is then determined
colorimetrically at 480 millimicrons.
METALS
Tables 22 through 68 present data on the concentrations of 16 metals in
urban and nonurban quarterly composites of samples collected during 1965, and
in earlier urban samples that have been analyzed in retrospect, some individually
and some as quarterly composites. Detectable quantities of antimony, beryllium,
bismuth, cadmium, cobalt, and molybdenum are found so infrequently that data
for these metals are presented in abbreviated summary tables.
In the metals analysis an aliquot of the sample is first ashed and then ex-
tracted with nitric acid. The manner of ashing the sample may be critical in
the determination of the more volatile metals, such as lead, zinc, and cadmium.
In the past, samples have been ashed in a muffle furnace at 500°C, but they are
now ashed in a low-temperature (less than 100°C) asher. After ashing and ex-
traction, metals contents of urban samples are determined with an emission
spectrograph.
This report contains summaries of the first extensive metals analyses of
nonurban samples, collected from 29 nonurban stations in 1965. Improvements
in the analytical method, including preparation of sample extracts up to five times
more concentrated than those for the urban samples, have so increased sensi-
tivity that metals can be detected in many nonurban samples.
Table 3 lists the minimum quantities in which metals,are detectable in
urban and nonurban samples under average operating conditions. The degree
of interference from other substances determines the actual sensitivity in an
individual analysis. In this publication, a recorded concentration of zero means
only that the actual concentration was below the minimum detectable. However,
in the calculation of annual station averages, concentrations below the minimum
detectable are treated as zero concentrations.
SOILING INDEX
Table 69 presents frequency distributions of soiling index values measured
at the six CAMP stations, and Table 70 presents daily averages of these values.
Soiling index values are determined with a standard AISI tape sampler operating
on a 2-hour cycle. The soiled tapes are read with an automated transmissivity
30
-------
meter that determines the soiling index values. Since the transmittance of light
through the soiled spot is affected primarily by the surface areas of the particles
collected, soiling index values reflect mainly the smaller particles. When
values over 6. 0 are indicated, the soiled spot is so dense that an accurate deter-
mination is not possible. Such values are under-estimated, that is they are lower
than would be the average of two 1-hour determinations.
GASEOUS POLLUTANTS
Tables 71 through 82 present various summaries of gaseous pollutant data
from three of the National Air Surveillance Networks: The Continuous Air
Monitoring Program (CAMP), the 24-hour gas bubbler network, and the lead
candle network.
The CAMP data are presented in Tables 71 through 76 as monthly and
annual frequency distributions of the basic 5-minute values recorded. Tables 77
through 82 present daily arithmetic averages of the data.
Data from the gas bubbler network on ammonia, nitrogen dioxide, and
sulfur dioxide are presented in Tables 83, 84, and 85, respectively. The gas-
bubbler samplers are operated on the same schedule of 26 randomly selected
days as are the "Hi-Vol" samplers. The tables include data from both "qualify-
ing" and "non-qualifying" stations. If a station did not meet the criterion of 20
properly distributed samples, the geometric mean and standard deviation were
not calculated. The nitrogen dioxide bubbler design was modified during 1966,
and the calibration constants were recalculated; therefore, nitrogen dioxide
bubbler data for 1966 cannot be considered strictly comparable with data from
years prior to 1966.
Tables 86 presents the results of the first partial year of operation of the
lead candle network. The lead candle provides an index of sulfation, which is
determined by the reaction of sulfurous compounds with lead peroxide exposed
to the air for 30 days, and which is expressed in milligrams of sulfur trioxide
per 100 square centimeters per day. The lead candle consists of a gauze sleeve
impregnated with lead peroxide and housed in a circular shelter to assure uniform
directional exposure.
COLORADO STATE NETWORK
Tables 87 and 88 present data provided by the Colorado State Network.
These data on suspended particulates and benzene-s oluble organics are not
integrated with other data.
