The APTD (Air Pollution Technical Data) series of reports is issued by the
Office of Air Programs, Environmental Protection Agency, to report technical data
of interest to a limited number of readers. Copies of APTD reports are available
free of charge to Federal Employees, current contractors and grantees, and non-
profit organizations--as supplies permit—from the Air Pollution Technical In-
formation Center, Environmental Protection Agency, Research Triangle Park, North
Carolina 27711 or may be obtained, for a nominal cost, from the National Technical
Information Service, 5285 Port Royal Road, Springfield, Virginia 22151.

The data reported in this publication could not have been gathered without
the generous cooperation of the many State and local air pollution agencies in the
operation of the NASN sampling stations. The Environmental Protection Agency
offers sincere thanks to these organizations and to their employees.

ABSTRACT
Air quality data for sulfur dioxide 1969 through 1971, urban and nonurban
sites, are presented. The data reported have been gathered at the cooperating
stations of the National Air Surveillance (NASN) network.
The sulfur dioxide samples were collected by bubbling air through a solution
of potassium tetrachloromercurate and analyzed using the West Gaeke method. Valid
data are presented as annual sample cumulative frequency distributions. The arith-
metic and geometric mean are included.

AIR QUALITY DATA FOR SULFUR DIOXIDE
1969, 1970, AND 1971
SECTION 1. INTRODUCTION AND SUMMARY
The Environmental Protection Agency (EPA), with the assistance and cooperation
of State and local agencies, conducts a variety of air sampling activities to ob-
tain information about the air quality in the United States. Data on sulfur
dioxide (S02) collected during 1969, 1970 and 1971 at the cooperating stations of
the National Air Surveillance Networks (NASN) are reported.
SAMPLE COLLECTION AND ANALYSIS
Sulfur dioxide is collected by bubbling air through a 50 milliliter solution
of potassium tetrachloromercurate at a flow rate of approximately 150-200 c.c./
minute over a 24-hour sampling period. After collection the sample is returned to
the laboratory where sulfamic acid is added to eliminate the interference from the
oxides of nitrogen, and the resulting solution is reacted with pararosaniline and
formaldehyde. The light absorption of the resulting solution is measured colori-
metrically, at a wavelength of 548 nanometers. The results are expressed in micro-
grams of S02 per cubic meter of air samples. Because decay of the collecting
solution containing S09 occurs at the rate of about one percent per day, the NASN
t- i
samples are analyzed on the 14th day after the specified sampling date (permitting
the use of a uniform decay correction).
SAMPLING LOCATIONS
The monitoring sites are divided into two groups: urban sites (Tables 2-1,
3-1, and 4-1), located somewhere within a city or town or its suburban environs,
and nonurban sites (Tables 2-2, 3-2, and-4-2) located in rural or remote areas to
provide an indication of background levels of SO-
11/72
-------
Each monitoring site is assigned a unique code number. Details of site coding
2
and a list of codes already assigned are found in SAROAD Station Coding Manual.
Briefly, each twelve digit site identification number is assigned as follows: the
first two digits identify the State, the next four digits identify a city of at
least 2500 persons or a county (in some States the corresponding jurisdiction is a
parish, election district, or regional planning district). The next three digits
designate a specific address where the sampling equipment is operated. For example,
010380001 A 01 refers to State 01 (Alabama) city 0380 (Birmingham), and site 001
(619 South 19th Street). The final three characters (A01) designate the agency-
project code. Some of the principal agency project codes are:
A01 EPA, population oriented surveillance
A03 EPA, background surveillance
F01 State agency, population oriented surveillance
GO! County agency, population oriented surveillance
HOI City agency, population oriented surveillance
3
A listing of sampling site addresses is available in a separate publication.
SAMPLING SCHEDULE
The NASN data within this section originate from a bi-weekly modified random
sampling schedule. The schedule is modified from completely random to insure an
equal representation of days of the week.
In order to have reasonable assurance that the annual summary statistics are
representative, each station's data must be distributed over the calendar year so
that they meet the following validity criteria for inclusion in this summary
publication: a minimum of five valid scheduled samples must be collected in each
quarter (Jan., Feb., Mar., etc.), and if no samples are collected in one month,
neither of the other two months may have less than two valid samples. Obviously,
it is desirable for networks that schedule more frequent sampling to strive for a
more balanced distribution of measurements than the possible extreme combinations
that could technically meet these minimum conditions for NASN stations.
DATA SUMMARIES
The data are presented as annual sample cumulative frequency distributions.
The frequency distributions are calculated by first ranking the values in ascending
order. Based on the total number of values, the percentiles are calculated such
that the percentage of actual sample values is less than or equal to the concen-
trations listed for that percentile. Interpolation between actual sample values
is not used. For example, if 25 samples were ranked in ascending order, ten
11/72
-------
percent of the samples would be 2.5 samples. So the concentration of the third
value is shown in the tenth percentile column. Similarly, the twentieth percentile
would be the fifth value.
When "zero" concentrations (shown as 0.0 in the data tables are reported, that
is, values below the minimum detectable limit, the statistics (means and standard
deviations) are calculated by replacing the "zeroes" with one half the minimum
detectable limit. For these summaries, the minimum detectable limit is 5 vg/m3,
so 2.5 yg/m is used to replace zeros for calculation purposes (In 1968 the
laboratory procedure set the minimum detectable limit at 5 yg/m3. However following
the measurement of a high value—above 50 ug/m3—the minimum detectable limit could
^
briefly change to 10 yg/m due to methodological problems. Because a high value was
observed less than 5 percent of the time, the minimum detectable limit of 5 yg/m3
was considered to be more representative of all data recorded during the year. In
subsequent years—I 970 and 1971—the method was remedied, eliminating this prob-
lem.) However, if between 25 and 50 percent of the values are below the detectable
limit, the summary statistics are not calculated. Finally, if more than 50 per-
cent of the values are below the detection limit, neither the summary statistics
nor the frequency percent!les are calculated and the following statement is pre-
sented: "Number of samples ( ) below the minimum detectable exceeds 50%."
In the example sample frequency distribution below, primary annual arithmetic
mean standard, (80 yg/m ) is met; the second and annual mean standard (60 yg/m3)
o
is exceeded. The maximum value, 305 vg/m , is below the primary standard for a
24-hour interval (365 yg/m3). By interpolating from the frequency distribution, it
can be estimated that just over ten percent of the measurements exceed the secondary
standard (280 yg/m3).
