                                ABOUT THIS REPORT
      This report presents the results and conclusions of the ambient air monitoring conducted as
part of the 1998 Urban Air Toxics Monitoring Program (UATMP)—a program designed to
characterize the magnitude and composition of potentially toxic air pollution in, or near, urban
locations. The 1998 UATMP included 12 monitoring stations that collected 24-hour air samples,
typically on a biweekly basis. These samples were analyzed for concentrations of 59 volatile
organic compounds (VOC) and 16 carbonyls.  Overall, nearly 28,000 ambient air concentrations
were measured during the 1998 UATMP. The summary presented in this report uses various
graphical, numerical, and statistical analyses to put the vast  amount of ambient air monitoring
data collected into perspective.

      Not surprisingly, the ambient air concentrations measured during the program varied
significantly from city-to-city and from season to season. This report describes and interprets
these spatial and temporal variations separately for halogenated hydrocarbons,  hydrocarbons,
polars, and carbonyls.

      The ambient air monitoring data collected during the 1998 UATMP serve a wide range of
purposes. Not only do these data characterize the nature and extent of urban air pollution close to
the 12 monitoring stations participating in this study, but they also  indicate some trends and
patterns that may be common to all urban environments. Therefore, this report presents some
results that are specific to particular monitoring locations and present other results that are
apparently common to urban environments. These results ultimately should provide additional
insight into the complex nature of urban air pollution. The final data are also included in the
appendices to this report.

      It should be noted that this is the last reporting year for acrolein, a carbonyl compound.  An
Addendum to the Compendium Method TO-11A for the Determination of Formaldehyde in
Ambient Air using Adsorbent Cartridge Followed by High Performance Liquid Chromatography
(HPLC) was presented on April 15,  1999. It states that "TO-11A is not applicable for acrolein."
Crotonaldehyde is another compound that appears to decompose rapidly after being introduced to
the cartridge. At this time, however, the U.S. EPA National Program is not deleting
crotonaldehyde from the carbonyl target list.

1.0    Introduction
       Air pollution in urban locations contains many components that originate from a wide
range of industrial, motor vehicle, and natural emissions sources. Because some of these
components include toxic compounds known or suspected to be carcinogenic, the
U.S. Environmental Protection Agency (EPA) continues to encourage state and local agencies to
understand and appreciate the nature and extent of potentially toxic air pollution in urban
locations.  To achieve this goal, EPA sponsors the Urban Air Toxics Monitoring Program
(UATMP), a program designed to characterize the composition and magnitude of urban air
pollution through extensive ambient air monitoring. Since the inception of the UATMP in  1987,
many environmental and health agencies have participated in the UATMP to assess the causes and
effects of air pollution within their jurisdictions. This report summarizes and interprets the 1998
UATMP monitoring effort, which included 1 year of biweekly measurements of ambient air
quality in or near 12 urban locations. Much of the analysis and data interpretation in this report
focuses on compound-specific data trends.

important air quality issues. For example, participating agencies can use trends and patterns in the
UATMP monitoring data to determine whether levels of air pollution present public health
concerns, to identify which emissions sources most strongly contribute to air pollution, or to
forecast whether proposed pollution control initiatives might significantly improve air quality.

2.0    The 1998 UATMP
       The 1998 UATMP included 12 monitoring stations that collected 24-hour integrated
canister and cartridge samples of ambient air on a biweekly basis for 12 months. These samples
were analyzed in a central laboratory for concentrations of selected hydrocarbons, halogenated
hydrocarbons, and polar compounds from the canister samples and carbonyls from the cartridge
samples. The following discussion reviews the monitoring locations, the compounds selected for
monitoring, the sampling schedules, the completeness of the 1998 UATMP, and the sampling
and analytical methods.

2.1    Monitoring Locations
       Although EPA sponsors the UATMP, EPA does  not dictate where the UATMP
monitoring stations are located.  Rather, representatives from the state and local agencies that
voluntarily participate in the program and contribute to the overall monitoring costs select the
monitoring locations.  Some monitors were placed near the centers of heavily populated cities
(e.g., Baton Rouge, Camden, and El Paso), while others were placed in moderately populated
areas (e.g., Garyville and Hahnville). One site was intentionally placed many miles distant from
urban centers (Underbill) because it was used by the State of Vermont as a background site. The
monitoring stations participating in the UATMP program are listed in Table 2-1.

       Figure 2-1 shows the  12 monitoring locations of the 1998 program.  The maps in
Figures 2-2 through 2-25 and the site descriptions in Table 2-2 and in Appendix A provide
detailed information on the surroundings at the 12  1998 UATMP monitoring locations.
Figures 2-2 through 2-13 illustrate the locations and surroundings of each monitoring site.
Figures 2-14 through 2-25 show the numbers and locations of facilities within 10 miles of the
monitoring sites that reported to the Toxics Release Inventory (TRI) in 1997.

       As Figure 2-1 shows, most of the 1998 UATMP monitors were located either near the
coast of the Gulf of Mexico or in the state of Vermont. Although this spatial distribution of
monitoring stations clearly is not a statistically significant sample of urban locations in the
                                          2-1

United States, the monitoring data from these stations may indicate certain air quality trends that
are common to all urban environments. The analyses in this report differentiate those trends that
appear to be site-specific from those that appear to be common to urban environments.

       Chemical concentrations measured during the 1998 UATMP varied significantly from
monitoring location to monitoring location.  As discussed throughout this report, the proximity
of the monitoring locations to different emissions sources, especially industrial facilities and
heavily traveled roadways, often explains the observed spatial variations in ambient air quality.
To provide a first approximation of the respective contributions of motor vehicle emissions and
industrial emissions on each site's ambient air quality, Table 2-3 lists the number of people living
within 10 miles of each monitoring location, as well as the number of industrial facilities that
meet EPA's TRI reporting requirements.

       At every UATMP monitoring location, the air sampling equipment was installed in a
small temperature-controlled enclosure (usually a trailer or a shed) with the sampling inlet probe
protruding through the roof.  With this common setup, every UATMP monitor sampled ambient
air at heights approximately  5 to 20 feet above local ground level.

       For recordkeeping and reporting purposes, each of these locations was assigned:
       A unique four-character UATMP site code - used to track samples from the monitoring
       locations to the laboratory; and
       A unique nine-digit AIRS site code - used to index monitoring results in the AIRS
       database.
This report often cites these codes when presenting selected monitoring results.
                                           2-2

2.2    Compounds Selected for Monitoring
       Urban air pollution typically contains hundreds of components, including, but not limited
to, volatile organic compounds (VOCs), metals, inorganic acids, and particulate matter.  Because
sampling and analysis to monitor for every component of air pollution has been prohibitively
expensive, the UATMP instead focuses on measuring ambient levels of 59 VOCs
(13 hydrocarbons, 37 halogenated hydrocarbons, and 9 polar compounds) and 16 carbonyls.
Tables 2-4, 2-5, and 2-6 identify the specific compounds of interest.

2.3    Sampling Schedules
       Table 2-7 presents the dates on which sampling began and ended for each monitoring
location. With the following exceptions, the monitoring locations began the  1998 UATMP
sampling in September 1998 and stopped sampling in September 1999:
       Because the monitoring station was not ready at the beginning of the study period, the
       Beulah, North Dakota, site did not begin sampling until February 1999. Sampling at this
       site continued until September 1999.
       As planned by the State that sponsored these stations, sampling was discontinued at the
       Arkansas sites (Texarkana and North Little Rock) at the end of March 1999.
       According to the UATMP schedule, 24-hour integrated samples were to be collected at
every monitoring location once every 12 days and each sample collection began and ended at
midnight, local standard time. At each test site, VOC and carbonyl samples were collected
concurrently. As part of the sampling schedule, site operators were instructed to collect duplicate
samples on roughly 10 percent of the sampling days.  In cases where monitors failed to collect
valid samples on a scheduled sampling day, site operators sometimes rescheduled samples for
other days.  This practice explains why some monitoring locations periodically strayed from the
12-day sampling schedule.

       The 12-day sampling schedule permits cost effective data collection for characterization
(annual-average concentrations) of toxic compounds  in ambient air and ensures that sampling

                                          2-3

-------
days are evenly distributed among the 7 days of the week which allows for comparison of air
quality on weekdays to air quality on weekends.

2.4    Completeness
       Completeness refers to the number of valid samples collected compared to the number of
samples expected from a 12 day sample cycle. Monitoring programs that consistently generate
valid results have higher completeness than programs that consistently invalidate samples. The
completeness of an air monitoring program, therefore, is a qualitative measure of the reliability of
air sampling equipment and laboratory analytical equipment and a measure of the efficiency with
which the program was managed.

       Appendices B (VOC) and C (carbonyl) identify samples that were invalidated and list the
specific reasons why the samples were invalidated. Table 2-7 summarizes the completeness  of
the VOC and carbonyl data sets collected during the 1998 UATMP:

•      For VOC sampling, the completeness ranged from 58 to 106 percent, with an overall
       completeness of 91 percent.
•      For carbonyl sampling, the completeness ranged from 55 to 110 percent with an overall
       completeness of 88 percent.
       According to the UATMP data quality objectives (USEPA, 1988), at least 15 ambient air
samples from a given monitoring station must be analyzed successfully to generate a sufficiently
complete data set for estimating annual average air concentrations. The data in Table 2-6 show
that all of the 1998 UATMP monitoring stations met this data quality objective. Because the
samples taken in Beulah, ND, Texarkana and North Little Rock, AR, were collected for only
7 months of the 12 month sampling period, the monitoring data from these stations do not
characterize seasonal  variations in air quality. Thus, central tendency concentrations for these
stations might not represent actual annual average levels.

2.5    Sampling and Analytical Methods
       During the 1998 UATMP, two EPA-approved methods were used to characterize urban
air pollution:
       Compendium Method TO-15 was used to measure ambient air concentrations of
       58 VOCs;
       Compendium Method TO-11A was used to measure ambient air concentrations of
       16 carbonyl compounds.
       The following discussion presents an overview of these sampling and analytical methods.
For detailed descriptions of the methods, readers should refer to EPA's original documentation of
the Compendium Methods (USEPA, 1999a).

       2.5.1  VOC Sampling and Analytical Method
       As specified in the EPA method, ambient air samples for VOC analysis were collected in
passivated stainless steel canisters. The central laboratory distributed the prepared (i.e., cleaned
and evacuated) canisters to the UATMP monitoring stations before each scheduled sampling
event, and site operators connected the canisters to air sampling equipment prior to each
sampling day. Before their use in the field, the passivated canisters had internal sea level
pressures much lower than atmospheric.  Because of this sea level pressure difference, ambient
air naturally flowed into the canisters once they were opened, and pumps were not needed to
collect ambient air for VOC analysis. A flow controller on the sampling device ensured that
ambient air entered the canister at a constant rate across the collection period.  At the end of the
24-hour sampling  period, a solenoid valve automatically stopped ambient air from flowing into
the canister, and site operators returned the canisters to the central laboratory for analysis.

       By analyzing each  sample with gas chromatographic analysis incorporating mass
selective detection and flame ionization detection (GC/MSD-FID), laboratory staff determined
ambient air concentrations of 59 VOCs (13 hydrocarbons, 37 halogenated hydrocarbons, and
                                          2-5

-------
9 polar compounds) within the sample. Because w-xylene and p-xylene elute from the GC
column at the same time, the VOC analytical method reports only the sum of the concentrations
for these two compounds, and not the separate concentrations for each compound.

      Table 2-4 lists the method detection limits for the laboratory analysis of the VOC
samples.  Although the sensitivity of the analytical method varies from compound to compound,
the detection limit reported by the analytical laboratory for every compound is lower than
0.25 parts per billion by volume (ppbv); most of the detection limits were below 0.1 ppbv. VOC
detection limits ranged from 0.02 to 0.21 ppbv. Speciated Nonmethane Organic Compound
(SNMOC) detection limits are expressed in parts per billion Carbon (ppbC) and ppbv.

      Because nondetect results significantly limit the range of data interpretations for ambient
air monitoring programs, participating agencies should note that  the approach for treating
nondetects may slightly affect the magnitude of the calculated central tendency concentrations,
especially for compounds with a  low prevalence. Following the  approach used to process the
1995 - 1997 UATMP monitoring data, data analysts replaced all nondetect observations with
concentrations equal to one-half of the compound's corresponding method detection limit. This
is the approach recommended for risk assessments involving environmental monitoring data
(USEPA, 1988).

      This year, the first reportable SNMOC analysis option was presented with the standard
VOC sampling. The only state that applied for this option was Vermont.  Data analysis will
begin for the SNMOCs when there are 2 years of data collected.  These data are presented in
Appendix F, with the VOCs. Table  2-5 lists the method detection limits for the laboratory
analysis of the SNMOC samples.

       2.5.2   Carbonyl Sampling and Analytical Method
       Following the specifications of EPA Compendium Method TO-11 A, ambient air samples
for carbonyl analysis were collected by passing ambient air over  silica gel cartridges coated with
2,4-dinitrophenylhydrazine (DNPH), a compound known  to react selectively and reversibly with

                                          2-6

-------
many aldehydes and ketones. Carbonyls in ambient air remain within the sampling cartridge,
while other compounds pass through the cartridge without reacting with the DNPH-coated
matrix.  As with the VOC sampling, the central laboratory distributed the silica gel cartridges to
the monitoring locations, and site operators connected the cartridges to the air sampling
equipment. After each 24-hour sampling period, site operators returned the cartridges to the
central laboratory for chemical analysis.


       To quantify concentrations of carbonyls in the sampled ambient air, laboratory analysts
eluted the exposed silica gel cartridges with acetonitrile. This solvent elution liberated a solution
of DNPH derivatives of the aldehydes and ketones collected from the ambient air. High-
performance liquid chromatography (HPLC) analysis and ultraviolet detection of these solutions
determined the relative amounts of individual carbonyls present in the original air sample.
Because butyraldehyde and isobutyraldehyde elute from the HPLC column at the same time, the
carbonyl analytical method can report only the sum of the concentrations for these compounds,
and not the separate concentrations for each compound. For the same reason, the analytical
method reports only the sum of the concentrations for the three tolualdehyde isomers, as opposed
to reporting separate concentrations for the three individual compounds.

       Table 2-6 lists the detection limits reported by the analytical laboratory for measuring
concentrations of 14 carbonyls.  Although the sensitivity of the analytical method varies from
compound to compound, the detection limit reported by the analytical laboratory for every
compound is less than or equal to 0.005 ppbv.  Carbonyl detection limits ranged from 0.002 to
0.005 ppbv.

       When reviewing these data, readers should keep in mind that data analysts replaced all
nondetect observations with concentrations equal to one-half of the compound's corresponding
detection limit.

         Monitoring
           Location
                               Description of the Immediate Surroundings
      Baton Rouge, LA
Of the 1998 UATMP monitoring locations, Baton Rouge has the third highest population density within ten
miles of the monitoring station.  Located in downtown Baton Rouge, the monitoring site is in the back parking
lot of an office building, directly across from the city motor pool. Numerous industrial facilities, including
refineries and chemical manufacturing plants, are located within a ten mile radius. Interstate Highway 110
passes within two blocks of the monitoring station.
      Beulah, ND
to
UJ
Beulah, North Dakota, located in Mercer County, is a rural, agricultural area with primarily wheat, small grains,
and cattle farms.  There are six lignite coal-fired power plants within thirty miles of Beulah, one to the east-
southeast; one to the northeast; two to the east; one to the northwest; and one to the southwest.  There is a
petroleum refinery and a lignite coal-fired power plant fifty miles southeast of Beulah. There is a lignite coal
mine located north of the town, one to the south-southwest of town and one to the southeast of town.  The
monitoring station is located in the approximate area of two coal-fired power plants and a coal  gasification
plant (the only functioning one in the nation). There is one power plant seven miles to the southwest of the
monitoring station; another is six miles to the northwest; and the gasification plant is five miles to the
northwest.
      Brattleboro, VT
Brattleboro, a small city in southern Vermont, has the second lowest population density of the 1998 UATMP
monitoring locations. The monitoring station is located north of town in a vacant lot adjacent to a farm and
garden center.  The monitoring station is in a moderately industrial area, not immediately adjacent to heavily
traveled roadways. Interstate Highway 91 passes within one mile of the monitoring station.
      Burlington, VT
Burlington is Vermont's largest city, but it is moderately sized by national standards. The monitoring site is in
the center of downtown Burlington, near several heavily traveled streets, two large parking lots, and two gas
stations.
      Camden, NJ
A suburb of Philadelphia, Pennsylvania, Camden has the highest population density of the 1998 UATMP
monitoring locations.  Although the monitoring site is in a residential area, numerous industrial facilities and
busy roadways are located within a ten mile radius. The monitors are situated in a parking lot of a business
complex.
      El Paso, TX
Located in western Texas, just across the border from Mexico and near the border of New Mexico, the region
surrounding the El Paso monitoring station has the second highest population density of the 1998 UATMP
monitoring locations. The monitoring site is located downtown, in a high-traffic area.

           Location
                               Description of the Immediate Surroundings
      Garyville, LA
Garyville is a small town located on the Mississippi River between the cities of Baton Rouge and New Orleans.
The monitoring site is located on the property of the Garyville Elementary School. A large refinery and other
industrial facilities are located nearby.
      Hahnville, LA
Hahnville, another Mississippi River town, is located approximately 15 miles southeast of Garyville. A large
refinery is located directly across the river from the monitoring station, and many other industrial facilities are
located in close proximity. Total TRI-reported emissions from facilities near the Hahnville monitoring station
were second highest among TRI emissions associated with the 1998 UATMP monitoring locations.
to
      North Little
      Rock, AR
The downtown area of the largest city in Arkansas, Little Rock, is directly across the Arkansas River from the
monitoring station.  Three interstate highways (1-30,1-40, and 1-630), and numerous heavily traveled streets
pass within approximately one mile of the monitoring station. The monitors are adjacent to a railroad track, a
diesel tank farm, vacant land, a residential neighborhood, and the river.
      Rutland, VT
Rutland is a moderately sized city in central Vermont. The monitoring station is located in a parking lot in
downtown Rutland. A heavily traveled state highway and several busy city streets run within 1 mile of the
monitoring station.
      Texarkana, AR
The monitoring station is located in a cow pasture, about ten miles south of Texarkana, Arkansas, and less than
one mile east of the Texas-Arkansas border, in an area with low density population and minimal effects of
motor vehicle traffic. There are no interstate highways and very few heavily traveled roads in the immediate
vicinity of the monitors. Some large industrial facilities include a paper mill and a natural gas purification plant
located within several miles of the monitoring station.
      Underbill, VT
The Underbill monitoring site is located in a rural area, about 20 miles east of Burlington. The site is at the
base of Mount Mansfield, in a remote field surrounded by forest over 10 miles from a city with population
greater than 10,000. Not surprisingly, the area surrounding the Underbill monitoring station has very low
population density and the lowest total emissions from industrial facilities of the 1998 UATMP monitoring
locations. Consequently, this site is viewed as a background site by the State of Vermont.

      c The El Paso, Texas, monitoring station is located less than 10 miles from the United States-Mexico border. Because only U.S. census and industry data were
      reviewed for this study, the listed site characteristics may understate the actual population and number of industrial sources near these monitoring stations.
      A The center of the City of Essex Junction (population 18,489) is 11.1 miles from the Underbill monitoring site.  The population within 10 miles of UNVT
      includes one half of the Essex Junction population.

Notes:  The carbonyl detection limits are based on a sample volume of 500 liters of ambient air.

       Because butyraldehyde and isobutyraldehyde elute from the HPLC column at the same time, the carbonyl
       analytical method can only report the sum of concentrations for these two compounds and not
       concentrations of the individual compounds. For the same reason, the analytical method also reports only
       the sum of concentrations for the three tolualdehyde isomers, as opposed to reporting separate
       concentrations for the three individual compounds.

* Acrolein was deleted from the Compendium Method TO-11A half way through the 1998 sampling season.
Acrolein will therefore no longer be analyzed for the annual UATMP reports.

3.0    Background Information: Ambient Air Monitoring Data Analysis and
       Interpretation
       This section presents a general overview of the methodology used to summarize and
interpret the ambient air monitoring data. In addition, basic information is presented concerning
emissions sources and various factors that potentially impact ambient air quality.

3.1    Air Monitoring Data Summary Parameters
       Because no single parameter can characterize the results of an extensive air monitoring
program, four parameters are used together in this report to indicate the nature and extent of air
pollution:

•      Prevalence;
•      Concentration range;
•      Central tendency; and
•      Variability.
       3.1.1  Prevalence
       In the context of the UATMP, prevalence refers to the frequency with which an air
pollutant is found at levels detectable by the corresponding sampling and analytical method. By
indicating the frequency of detection, prevalence can help participating agencies identify
compounds of concern in urban air pollution. Because this report is organized to evaluate trends
in ambient air quality primarily on the basis of compound groups, the prevalent compounds are
identified on a program-wide, not site-specific, basis.
                                           3-1

-------
       More importantly, the number of nondetects for a given compound (indicated by low
prevalence) must be considered when interpreting air monitoring results.  Specifically, annual
average concentrations cannot be accurately estimated for compounds that are not detected in a
majority of samples (see Section 3.1.3).  Other limitations posed by compounds having low
prevalence are discussed throughout this report.

       When reviewing the data summary tables, readers should note that a prevalence of zero
does not necessarily indicate that a compound is not present in ambient air. Rather, compounds
with a prevalence of zero may be present in the air, but at levels consistently below method
detection limits.

       For the purposes of this report, a group of program-wide prevalent compounds was
identified for each of the compound groups (hydrocarbons, halogenated hydrocarbons, polar
compounds,  and carbonyls). These groups of program-wide prevalent compounds are discussed
in detail in Sections 5 through 8 of this report. Because the UATMP  does not characterize every
component of air pollution, many compounds known  to be prevalent in urban air (e.g., ozone and
nitrous oxides) are not considered in this report.  Readers should be careful not to confuse the
most program-wide prevalent compounds identified by the 1998 UATMP with the most
prevalent compounds in urban air pollution.

       Program-wide prevalent compounds were identified using two statistical parameters: the
count of the  number of nondetects (ND); and the percent contribution of their mass
concentrations. If a compound was detected in at least 75 percent of all the samples, and if the
compound contributed to at least 90 percent of the mass concentration within a compound group,
then that compound was initially considered "program-wide prevalent". Twenty compounds met
both of these criteria (7 halogenated hydrocarbons, 8 hydrocarbons, 1 polar compound, and
4 carbonyls).
                                          3-2

-------
       In order to provide a more statistically significant analysis, the following changes were
made to the list of compounds initially identified as "program-wide prevalent":
       Because only one polar compound was initially classified as program-wide prevalent
       (methyl ethyl ketone), the next two highest polar compounds (acetonitrile and methyl-
                ether) were added.
•      Because the number of halogenated hydrocarbons considered in the UATMP is more than
       twice for hydrocarbons (28 to 12), the next two highest halogenated hydrocarbons were
       added (tetrachloroethylene and /?-dichlorobenzene), while the lowest "program-wide
       prevalent" hydrocarbon was removed (1,2,4-trimethylbenzene).

       3.1.2   Concentration Range
       For a given compound, concentration range refers to the span of measured
concentrations, from lowest to highest. To indicate concentration range, the summary tables in
Appendices D and E present the lowest and highest concentrations measured for each compound
at each monitoring location. For most compounds, at least one sample at a given site resulted in
a nondetect, so the lowest concentration reported is "ND."  For compounds not detected in any
samples at a site, both the lowest and the highest concentrations are reported as "ND."

       Participating agencies  might use these ranges to assess worst-case air pollution episodes,
which can result from large one-time releases from industrial facilities or from atypical
meteorological conditions. Peak concentrations also are useful for determining whether ambient
air concentrations of acutely toxic compounds ever reach unsafe levels. However, because
samples were collected only once every 12 days, it is possible that ambient air concentrations on
some nonsampling days were  higher than the "highest" concentration cited in the data summary
tables. As a result, the highest concentrations cited in the UATMP summary tables are only
estimates of the actual concentration peaks.
                                           3-3

-------
       3.1.3   Central Tendency (Annual Average Concentrations)
       Annual average ambient air concentrations are useful for many purposes, such as
comparing air quality to environmental regulatory standards, evaluating what health effects might
result from long-term exposure to air pollution, and assessing long-term trends in urban air
quality. Although the UATMP does not directly measure annual average concentrations, these
concentrations can be estimated as the central tendency of the distribution of a sufficient number
of 24-hour average measurements. As discussed in Section 2.4, with the exceptions of the
Beulah, ND, Texarkana and North Little Rock, AR, monitoring sites, all of the annual UATMP
monitoring stations collected valid 24-hour average ambient air samples on at least 15 days during
the  1998 program.  This level of completeness ensures an adequate number of sampling days for
estimating annual averages, according to the UATMP data quality objectives (USEPA, 1988).

       Ambient air monitoring studies typically cite medians, arithmetic means, or geometric
means as estimates of the central tendency of concentration distributions. Despite their common
use, these three parameters can have significantly different values for the same distribution of
ambient air monitoring data. By definition:

•      Arithmetic means are the central tendencies of normally distributed data;
•      Geometric means are the central tendencies of lognormally distributed data; and
•      Medians are the midpoints of any data set.

Extensive analyses of the 1995 UATMP monitoring data showed that ambient air monitoring data
for  both VOCs and carbonyls generally fit lognormal distributions more closely than they fit
normal distributions (ERG, 1997). This rinding suggests that the geometric mean is a more
appropriate measure of central tendency concentrations than either arithmetic means or medians.
This conclusion has been reported in several other ambient air monitoring studies (Radian, 1990;
Radian, 1991; Gilbert, 1987).  Nonetheless, the ambient air monitoring  summary tables in
Appendices D and E include arithmetic mean, median, and geometric mean concentrations to
                                          3-4

-------
allow readers to compare UATMP results with monitoring studies that use these other data
summary parameters.


       To calculate representative arithmetic mean, median, and geometric mean concentrations,
all nondetects and duplicate sampling results in the UATMP monitoring database were processed
to assign each compound just one numerical concentration for each successful sampling day.
Following the approach used to process the 1995, 1996, and 1997 UATMP monitoring data:
       Data analysts first replaced all nondetect observations with concentrations equal to
       one-half of the compound's corresponding detection limit. This approach is
       recommended for risk assessments involving environmental monitoring data (USEPA,
       1989).

       Due to replicate analyses of duplicate samples, some sampling dates may have produced
       four different concentrations.  For these dates, data analysts entered the average of the
       concentrations from duplicate sampling and replicate analyses, so that the  UATMP
       monitoring database included just one concentration for each compound for each
       sampling date.

-------
       Furthermore, because nondetect observations cannot be assigned an accurate
concentration, the number of nondetect results for a given compound limits the accuracy of the
central tendency calculation. As an extreme example, a compound never detected during the
UATMP has arithmetic mean, geometric mean, and median concentrations all exactly equal to
one-half of the compound's detection limit, even though the actual central tendency
concentration could be anywhere between zero and the detection limit.  This observation suggests
that central tendency concentrations for compounds with low prevalence (i.e., a large number of
nondetects) should be interpreted with caution.

       3.1.4  Variability
       Variability refers to the spread of data observations about their central tendency value.
Because emissions in urban areas and local meteorological conditions constantly change, ambient
air quality also changes from one day to the next.  By comparing data variability from compound
to compound, however, participating agencies might better characterize the emissions sources
that most significantly contribute to measured air concentrations for specific compounds.

       For example, varying wind speeds  and wind directions can cause emissions from
particular industrial facilities to impact the air quality at a monitoring location at some times and
not at other times.  Therefore, compounds emitted primarily from such sources would be
expected to have relatively high data variability.  Because motor vehicle emissions are typically
found throughout an urban area (as opposed to being found at only discrete locations), emissions
from motor vehicles are almost always expected to impact the air quality at monitoring locations,
with the extent of impact determined mainly by local meteorological conditions. Accordingly,
compounds emitted primarily from sources ubiquitous to urban environments (such as motor
vehicles) would  be expected to have relatively low data variability.

       This report uses two common measures of data variability to characterize fluctuations in
the UATMP air monitoring data:
                                           3-6

-------
       Standard deviations represent an absolute measure of variability, meaning that standard
       deviations are usually higher for data distributions on higher values.

       Coefficients of variation provide a relative measure of variability by expressing
       variations relative to the magnitude of the mean concentration. Thus, the coefficient of
       variation is an appropriate (but not ideal) descriptive statistic for comparing variabilities
       across distributions for different monitoring locations.
       Both standard deviations and coefficients of variation in this report were calculated from

the processed UATMP monitoring database: nondetect observations were assigned values equal

to one-half their corresponding detection limit and duplicate samples and replicate analyses

were replaced with a single average value.


3.2    Air Monitoring Data Interpretation Parameters


       3.2.1   Pearson Correlation Coefficients
       Data correlations measure the strength and direction of relationships between variables.

Applied to the UATMP monitoring  data, these correlations can identify notable trends and

patterns in the large volume of data  that may not be readily apparent from the data summary

parameters.  These trends and patterns, or lack thereof, ultimately characterize those factors that

most strongly affect levels of air pollution. This section presents a general overview of the

statistical methodology used to calculate data correlations; additional information regarding their

calculation can be found in most introductory statistics texts.


       This report uses Pearson correlation coefficients to measure the degree of correlation

between  two variables, specifically to answer these basic questions:
       To what extent are 24-hour average concentrations of one compound related to 24-hour
       average concentrations of other compounds measured at the same time at the same
       monitoring location?

       To what extent are ambient air concentrations of VOCs and carbonyls related to
       meteorological parameters (temperature, wind information, and amount of sunshine)?

                                           3-7

-------
       When calculating correlations among the UATMP data, several measures were taken to

identify spurious correlations and to avoid introducing bias to the correlations:
       The statistical significance of the Pearson correlation coefficients was evaluated using a
       standard t-test—a test commonly used for this purpose (Harnett, 1982). In this report,
       Pearson correlation coefficients were tested for statistical significance using the 5 percent
       level of significance. Whenever possible, a 95 percent confidence interval was calculated
       around the estimated correlation coefficient.  If zero did not fall within the interval, the
       coefficient was considered statistically significantly different from zero.

       Data correlations were calculated only for the most program-wide prevalent compounds
       listed in Sections 5 through 8.  Because the UATMP monitoring data are least precise for
       compounds having many nondetect observations (see Section 9), eliminating the less
       program-wide prevalent compounds improves the correlation analysis.

       Correlations were calculated from the processed UATMP monitoring database in which
       each compound has just one numerical concentration for each successful sampling date.
       Section 3.1 discussed the significance of using this processed database, in which nondetect
       observations, duplicate sampling events, and replicate laboratory analyses were all
       replaced with appropriate surrogate values. With these data quality measures, data
       analysts ensured that the calculated correlations characterize actual trends in the UATMP
       air monitoring data.
                                            3-8

-------
       3.2.2   Correlations Between Concentrations of Different Compounds
        For each sampling event at each monitoring location, Pearson correlation coefficients
were calculated to compare concentrations of the program-wide prevalent compounds from the
four groups of chemicals studied in the 1998 UATMP. Trends in the strength and direction
(positive or negative) of the correlations between the concentrations of compounds can lead to
insights concerning common emissions sources. Comparison of site-specific and general trends
can help determine if single or different factors impact ambient air concentrations of pollutants.
Sections 5 through 8 describe general trends among the calculated correlation coefficients to
offer insight into the origin of air pollution in urban locations.

       3.2.3   Correlations Between Concentrations and Meteorological Parameters
       The correlation between the measured ambient air concentration of a compound and the
corresponding daily temperature provides a measure of how ambient air concentrations vary with
temperature and how they vary with season. Compounds that tend to have higher concentrations
in the summer months generally have positive correlations with temperature; compounds with
higher concentrations during the winter months have negative correlations with temperature; and
compounds with ambient air concentrations unaffected by season are usually uncorrelated with
temperature.  Ultimately, the magnitude and direction of seasonal variations in ambient air
monitoring data provide insight into the factors that most strongly affect air quality. Sections 5
through 8 describe general trends among these calculated correlation coefficients.

       To characterize the relationship between temperature and the 1998 UATMP monitoring
data, a set of temperature-concentration Pearson correlation coefficients was calculated for each
compound group at each monitoring location. These correlations evaluated how  ambient air
concentrations of each of the most program-wide prevalent compounds varied with the daily
maximum,  minimum, and average temperature on the corresponding sampling dates.  The
temperature data representative of each UATMP monitoring location were obtained from the
National Climatic Data Center (NCDC), an organization that oversees a network of
meteorological stations across the country.
                                          3-9

-------
       Wind, sea level pressure, dew point temperature, and visibility data were also obtained
for each UATMP monitoring location with the goal of determining if these meteorological
parameters could be correlated with the compound concentrations.  The wind speed and sea
level pressure are good indications of the ability of the atmosphere to mix.  Typically, slow-
moving stagnating air will favor the mechanisms of increased VOC and carbonyl production.
Dew point temperature can be an indication of the amount of moisture in the air, while the
visibility (measured in miles) provides a good indication of haziness.

3.3    Emissions and Atmospheric Processes
       Pollutants found in urban air come from a wide range of emissions sources.  Industrial,
motor vehicle, and natural emissions sources account for most pollutants found in urban air
(Graedel, 1978). The nature and magnitude of these emissions largely determine the chemical
composition of urban air pollution. Local meteorology and atmospheric chemistry, on the other
hand, determine how quickly emitted chemicals disperse and react in ambient air.

       3.3.1   Industrial Emissions  Sources
       Airborne chemical emissions from industrial facilities significantly contribute to air
pollution in urban centers. Industrial  air emissions are generally classified into two categories:
       Stack emissions from industrial facilities include all chemical releases through confined
       air streams, such as process vents and smoke stacks. Depending on the stack height and
       exit velocity, stack emissions may have maximum impacts on air quality at points close
       to, or several miles from, the point of release.
       Fugitive emissions account for all other chemical releases to the air from industrial
       facilities; typically, fugitive emissions result from evaporative losses and equipment leaks
       in chemical processing areas. Because fugitive emissions generally have no appreciable
       exit velocity and often occur close to ground level, these emissions have the greatest
       effect on air quality at locations closest to the point of release.
       The total amount of chemicals released from industrial sources into the air through stack
and fugitive emissions varies from urban area to urban area.  Federal, state, and local agencies
                                          3-10

-------
have prepared inventories of emissions data to estimate total quantities of air releases within their
jurisdictions. At the federal level, the TRI contains extensive emissions data for a wide range of
industries and provides an excellent reference for evaluating how industrial emissions might
impact ambient air concentrations of selected pollutants in different parts of the country.  The
accuracy of TRI data is not known, but TRI data accuracy is certainly dependent upon the
accuracy of emissions estimates provided by industrial facilities. Sections 5 through 8 compare
trends and patterns in TRI data to trends and patterns in the ambient air concentrations measured
during the 1998 UATMP.  Readers interested in more closely evaluating ambient air quality
measured at specific monitoring locations should also refer to inventories of emissions data
compiled by state and local agencies.

       3.3.2   Motor Vehicle Emissions Sources
       Like industrial emissions sources, motor vehicles contribute significantly to air pollution
in urban environments, so thorough analyses of urban air monitoring data must consider
contributions from motor vehicle sources. Pollutants found in motor vehicle exhaust generally
are combustion products or result from incomplete combustion of vehicle fuels. Although
modern vehicles and, more recently, vehicle fuels have been engineered to minimize air
emissions, all motor vehicles with internal combustion  engines emit a wide range of chemical
pollutants.  The magnitude of these emissions in urban  areas primarily depends on the volume of
traffic, while  the chemical profile of these emissions depends more on vehicle design and fuel
content. Several studies have generated chemical profiles of motor vehicle exhaust (Conner
et al., 1995), and such profiles provide additional context for analyzing spatial variations in
ambient air monitoring data.

       3.3.3   Natural Emissions Sources
       Many natural processes release volatile compounds to the air.  These processes include,
but are not limited to,  natural decay and biosynthesis in oceans and forests, fires in forests and
grasslands, and volcanic eruptions. Some studies have  reported that natural emissions may
exceed both industrial and motor vehicle emissions on a global scale.  In urban areas, however,
the contributions of industrial and motor vehicle sources to air pollution probably outweigh the
contribution of natural emissions. Accordingly, the data interpretations throughout this report
focus on how emissions from motor vehicles and industry affect air quality, with a much lighter
emphasis on the effect of emissions from natural sources.

       3.3.4   Atmospheric Fate and Transport
       Atmospheric fate and transport processes provide the link between emissions and ambient
air quality.  More specifically, atmospheric dispersion and photochemical reactions primarily
determine the fate of chemicals emitted into the air. Atmospheric dispersion refers to the natural
phenomena by which chemical emissions gradually move to regions of lower concentration by
convection and diffusion. The rate at which emissions  disperse depends on characteristics of the
                                           3-12

-------
emissions source (such as stack height and exit velocity) and on local meteorological conditions
(such as cloud cover and wind velocity). Photochemical reactions both consume and produce
pollutants in urban environments, and rates for the various reactions vary with temperature, solar
radiation, and chemical composition.

       Because atmospheric dispersion and photochemical reactions strongly affect the
composition and magnitude of air pollution, both factors should be considered in a thorough
review of ambient air monitoring data. Although sophisticated fate and transport computer
models allow for a detailed quantitative analysis of these factors (USEPA, 1986), extensive
site-specific modeling analyses are beyond the scope of this report.
                                          3-13

4.0    Summary of 1998 UATMP Data
       This section uses four parameters—prevalence, concentration range, central tendency, and
variability—to provide an overview of the ambient air monitoring data collected during the 1998
UATMP.  Sections 5 through 8 present more detailed interpretations of the trends and
correlations in the 1998 UATMP data.  Refer to the appendices for a complete presentation of the
data:

•      Appendix D: Summary Tables for VOC Monitoring
•      Appendix E:  Summary Tables for Carbonyl Monitoring
•      Appendix F: VOC Raw Monitoring Data
•      Appendix G: Carbonyl Raw Monitoring Data
4.1    Data Summary Parameters for VOCs
       Tables D-l through D-12 in Appendix D use the four data summary parameters defined
above to summarize the VOC monitoring results for the 1998 UATMP. The following paragraphs
review the basic findings indicated by the VOC data summary tables.
       4.1.1  Prevalence
       While the prevalence of VOCs in ambient air varied significantly from compound to
compound and from monitoring location to monitoring location, the majority of VOCs were
present at a prevalence greater than 75 percent at most of the monitoring locations. To simplify
data presentation and interpretation, for the purposes of this report, program-wide prevalent
compounds were identified within each compound group (hydrocarbons,  halogenated
hydrocarbons, polar compounds, and carbonyls). As discussed in Section 3.1.1, the most
                                         4-1

-------
program-wide prevalent compounds are defined as the top compounds measured across the
sampling sites in both number of nondetects and percentage contribution. The analyses and
interpretations throughout this report focus primarily on these most program-wide prevalent
compounds. For the 1998 UATMP, the program-wide prevalent VOCs are:
                                HYDROCARBONS
                     Acetylene
                     Benzene
                     Ethylbenzene
                     m-,p-xy\ene
                     o-xylene
                     Propylene
                     Toluene
                       «ALOGENATO> HYDROCARBONS
                     Carbon Tetrachloride
                     Chloromethane
                     /7-Dichlorobenzene
                     Dichlorodifluoromethane
                     Methylene Chloride
                     Tetrachloroethylene
                     1,1,1 -Trichloroethane
                     Trichlorofluoromethane
                     Trichlorotrifluoroethane
                              POLARCOMPOUNDS
                     Acetonitrile
                     Methyl Ethyl Ketone
                     Methyl tert-Butyl Ether
       Because these compounds were consistently present at detectable levels, the UATMP
monitoring data characterize ambient levels for these compounds much more accurately than they
                                        4-2

-------
characterize ambient levels for the VOCs with lower prevalence. Further, the high prevalence
allows for a meaningful statistical analysis of data correlations and a thorough review of spatial
variations and temporal variations in ambient air quality.

       Readers interested in examining data trends for the less program-wide prevalent
compounds more closely should refer to the summary tables in Appendix D and the raw
monitoring  data in Appendix F, but also should note the limitations posed by data sets with many
nondetect observations.

       4.1.2   Concentration Range
       To efficiently summarize the concentration ranges cited in Appendix D, Table 4-1
indicates the number of monitoring stations that detected peak VOC concentrations within certain
ranges.  These data show that peak concentrations, like prevalence, varied significantly among
compounds and monitoring stations.  During the 1998 UATMP, measured ambient air
concentrations of more than 80 percent of the VOCs identified by the analytical method never
exceeded 1  ppbv.  Specifically:
       More than 85 percent of the hydrocarbon compounds identified by the analytical method
       never exceeded 5 ppbv. Only w-octane never exceeded 1 ppbv.
       More than 94 percent of the halogenated hydrocarbon compounds identified by the
       analytical method never exceeded 1 ppbv; 99 percent never exceeded 5 ppbv. Only
       chloromethane and methylene chloride exceeded Ippbv in greater than 50 percent of the
       samples.
       More than 70 percent of the polar compounds identified by the analytical method never
       exceeded 1 ppbv; more than 90 percent never exceeded 5 ppbv. Only methyl ethyl ketone
       exceeded 1 ppbv in 100 percent of the samples at all sampling locations.

       4.1.3   Central Tendency

       Figures 4-1 through 4-3 illustrate how central tendency concentrations for the program-

wide prevalent VOCs varied from one monitoring location to the next.  Although the spatial

variations differ for each compound, the figure indicates several general data trends:

       The geometric mean concentrations of some compounds (particularly carbon
       tetrachloride, p-dichlorobenzene, dichlorodifluoromethane, and trichlorofluoromethane)
       are nearly uniform across the 12 UATMP monitoring locations, while the geometric mean
       concentrations for most other compounds exhibit significant spatial variations.

       The profiles of geometric mean concentrations of the program-wide prevalent
       hydrocarbons (Figure 4-1) are nearly identical across all monitoring stations, with
       relatively higher concentrations consistently occurring at the El Paso, Texas, and
       Burlington, Vermont, monitoring stations and with the lowest concentrations consistently
       occurring at the Underbill, Vermont, and Beulah, North Dakota, monitoring stations.

       The geometric mean concentration profiles for the program-wide prevalent polar
       compounds (Figure 4-3) exhibit dramatic differences. Acetonitrile is present in relatively
       high concentrations at only one monitoring location (Baton Rouge, Louisiana) and at or
       near the detection limit at the remaining 11 monitoring locations. Methyl terf-butyl ether
       is present in relatively high concentrations at only one site (Camden, New Jersey), at
       moderate concentrations at three other locations, and at or near the detection limit at the
       remaining monitoring sites.  Methyl ethyl ketone was reported from the Beulah, North
       Dakota monitoring location due to sampler contamination.

       The geometric mean concentrations of many compounds varied significantly, even among
       stations located in close proximity (e.g., Burlington,  Brattleboro, Rutland, and Underbill;
       Baton Rouge, Garyville, and Hahnville).

       4.1.4   Variability
       Table 4-2 lists, for each monitoring location, the three program-wide prevalent
compounds with lowest coefficients of variation and the three program-wide prevalent
compounds with highest.  Only program-wide prevalent compounds are considered in this table
because nondetect observations strongly influence variability.  As with the trends in central
tendency, the trends in variability vary from one site to the next, but some general trends are
apparent:
       Ambient air concentrations of dichlorodifluoromethane, carbon tetrachloride, and
       chloromethane had very low variability at most of the monitoring locations.
       Concentrations of acetonitrile, toluene, and methylene chloride consistently varied greatly
       during the 1998 UATMP.
4.2    Data Summary Parameters for Carbonyls
       Using the same four data summary parameters discussed in Section 4.1, the tables in
Appendix E provide an overview of the carbonyl monitoring results from the 1998 UATMP.  The
raw monitoring data are included in Appendix G. The following paragraphs review the basic
findings indicated by the carbonyl data summary tables.

       4.2.1   Prevalence
       Like the VOCs, prevalence of carbonyls in ambient air varied significantly from compound
to compound and from monitoring location to monitoring location.  With the exceptions of
2,5-dimethylbenzaldehyde, crotonaldehyde, and isovaleraldehyde, the carbonyls were generally
present at a prevalence greater than 75 percent at all of the monitoring locations. For the
purposes of this report, program-wide prevalent carbonyl compounds were identified. In the
1998 UATMP, the program-wide prevalent carbonyls are acetaldehyde, acetone,
butyl/isobutyaldehyde, and formaldehyde. As noted in Section 2.5.2, the carbonyl sampling and
analytical method cannot separate butyraldehyde and isobutryaldehyde, and instead reports the
                                           4-5

-------
sum of the concentrations for these two compounds, rather than reporting separate concentrations
for each compound.

       Readers interested in examining ambient air levels of less program-wide prevalent carbonyl
compounds should refer to the raw monitoring data in Appendix G and the data interpretation
methodologies in Section 8.

       4.2.2   Concentration Range
       Table 4-3 summarizes the highest concentrations of carbonyls measured during the 1998
UATMP. Like the VOCs, most carbonyls (greater than 75 percent)  had concentration peaks of
less than 1 ppbv. Specific trends identified include:
       At 11 of the 12 monitoring sites, acetone and acetaldehyde had peak concentrations
       greater than 1 ppbv.
       Formaldehyde had peaks greater than 1 ppbv at all of the monitoring stations and peaks
       greater than 5 ppbv at 6 of the 12 monitoring stations.
       4.2.3   Central Tendency
       Figure 4-4 illustrates how central tendency concentrations of the program-wide prevalent
carbonyl compounds varied among the 1998 UATMP monitoring locations.  Like the spatial
variations shown for VOC central tendency concentrations, the spatial variations for carbonyl
central tendency concentrations differ for each compound. Nonetheless, some general trends are
apparent:
       The profiles of central tendency concentrations illustrate that the highest concentrations
       typically occurred at Camden, New Jersey, and El Paso, Texas. This tendency of high
       concentrations of the compounds of interest in the samples from the El Paso monitoring
       site is also seen in the VOCs.
       No strong central tendency of low concentrations at a particular monitoring site is seen in
       the figure.
                                          4-6

-------
       4.2.4   Variability
       Along with the VOCs, Table 4-2 lists, for each monitoring location, the three compounds
with lowest coefficients of variation and the three with highest. Butyr/isobutyraldehyde is among
the least variable, while acetaldehyde is among the most variable, but these variability trends for
the carbonyl data are not as strong as those for the VOC data.

5.0    Data Interpretation: Hydrocarbons
       Hydrocarbons are organic compounds that contain only carbon and hydrogen.  The
hydrocarbons are derived mostly from crude petroleum and also from coal tar and plant sources
and are classified according to the arrangement of the atoms, as alicyclic, aliphatic, and aromatic.
Hydrocarbons are of prime economic importance because they encompass the constituents of the
major fossil fuels, petroleum and natural gas, as well as plastics, waxes, and oils.  In urban air
pollution, these components—along with oxides of nitrogen (NOX) and sunlight—contribute to the
formation of tropospheric ozone.

       As stated above, hydrocarbons in the atmosphere originate from natural sources and from
various anthropogenic sources, such as combustion of fuel and biomass, petroleum refining,
petrochemical manufacturing, solvent use, and gas and oil production and use.  Studies have
shown that emissions from different anthropogenic sources vary significantly from location to
location. For example, on a nationwide basis, EPA estimates that 50 percent of anthropogenic
nonmethane volatile organic compound releases in  1996 came from industrial processes,
42 percent from transportation, 6 percent from fuel combustion, and the rest from other sources
(USEPA, 1997). In urban areas, however, the estimated contributions of different source
categories differ from these national averages. For instance, a 1987 study  in the Los Angeles
area estimated that 49 percent of nonmethane hydrocarbon emissions come from vehicle exhaust,
11 percent from liquid gasoline, 10 percent from gasoline vapor, and 30 percent from sources
other than motor vehicles (Fujita et al., 1994). These figures suggest that motor vehicles may
play a greater role in hydrocarbon emissions in urban areas than national statistics indicate.

       As noted in Section 2, the sampling and analytical methods used in the 1998 UATMP
measure concentrations of 12 hydrocarbons, all of which  have fewer than ten carbon atoms.
These  12 hydrocarbons tend to be gases or volatile liquids under standard  atmospheric conditions
and are commonly referred to as VOCs. The discussions in this chapter center on the general
trends  observed for 7 program-wide prevalent hydrocarbons and consider  hydrocarbon
concentrations quantified at the 12 monitoring locations,  with respect to:

5.1    Correlations Between Concentrations of Different Compounds

       From the ambient air monitoring data collected for each sampling event at each site,

Pearson correlation coefficients were calculated to compare concentrations of the program-wide
prevalent compounds from the four groups of chemicals studied in the 1998 UATMP

(i.e., hydrocarbons, halogenated hydrocarbons, polar compounds, and carbonyls). The following

discussion summarizes the calculated correlations.
                                          5-2

-------
       5.1.1   Correlations Between Halogenated Hydrocarbons and Hydrocarbons
       Figure 5-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent halogenated hydrocarbons and
program-wide prevalent hydrocarbons.

       As the distribution of Pearson correlation coefficients in Figure 5-1 shows, ambient air
concentrations of the program-wide prevalent halogenated hydrocarbons measured during the
1998 UATMP were weakly correlated with ambient air concentrations of the program-wide
prevalent hydrocarbons. Approximately 25 percent of the correlation coefficients were between
+0.50 and +0.75, indicating a moderate positive correlation. Nearly 42 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation.  However, the
average correlation is statistically significant (0.250 ± 0.174) across the  12 sites.  These weak
correlations generally suggest that the factors that most strongly affect levels of halogenated
hydrocarbons in ambient air are different from the factors that affect ambient air concentrations
of hydrocarbons.

       5.1.2   Correlations Between Hydrocarbons and Polar Compounds
       Figure 5-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent hydrocarbons and program-wide
prevalent polar compounds.

       As the distribution of Pearson correlation coefficients in Figure 5-1 shows, ambient air
concentrations of the program-wide prevalent hydrocarbons measured during the 1998 UATMP
were very weakly correlated with ambient air concentrations of the program-wide prevalent polar
compounds. Approximately 16 percent of the correlation coefficients  were between +0.50 and
+0.75, indicating a moderate positive correlation.  Nearly 58 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation.  However, the
average correlation was statistically significant across the 12 sites (0.199 ± 0.152). These weak
correlations generally suggest that the factors that most strongly affect levels of hydrocarbons in
                                           5-3

-------
ambient air are different from the factors that affect ambient air concentrations of polar
compounds.

       5.1.3   Correlations Between Carbonyls and Hydrocarbons
       Figure 5-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent carbonyls and program-wide
prevalent hydrocarbons.

       The distribution of Pearson correlation coefficients in Figure 5-1 shows that ambient air
concentrations of the program-wide prevalent hydrocarbons measured during the 1998 UATMP
were weakly correlated with ambient air concentrations of the program-wide prevalent carbonyls.
Approximately 17 percent of the correlation coefficients were between +0.50 and +0.75,
indicating a moderate positive correlation.  Less than 50 percent of the correlation coefficients
were between -0.25 and +0.25, indicating very weak or no correlation.  The average correlation
was not statistically significant across the 12 sites (0.160 ± 0.175). These weak correlations
generally suggest that the factors that most  strongly affect levels of hydrocarbons in ambient air
are from the factors that affect ambient air concentrations of carbonyl compounds.

5.2    Correlations Between Concentrations and Temperature

       5.2.1 Temperature
       According to Table 5-1, the program-wide prevalent hydrocarbons generally had negative
correlations with maximum, minimum,  and average temperature across all 12 sites. This type of
correlation would suggest that increasing temperature would relate to decreasing measured
concentration of hydrocarbons.  The Brattleboro, VT, site had the strongest negative correlation
of hydrocarbon concentration for all three temperature parameters (-0.476, -0.549, and -0.554,
respectively).  The highest positive correlations of hydrocarbon concentration with these
meteorological parameters occurred at the Beulah, ND, site (0.318 and 0.134, respectively) while
the Little Rock site had the highest correlation with average temperature (0.228).

-------
       5.2.3  Dew Point Temperature and Visibility
       According to Table 5-1, the program-wide prevalent hydrocarbons had a negative
correlation with the dew point temperature. The strongest negative correlation occurred at the
Burlington, VT, site (-0.471).  The highest positive correlation of hydrocarbon concentration with
dew point temperature occurred at the Beulah, ND site (0.186).  Visibility also had a negative
correlation with the program-wide prevalent hydrocarbons (-0.158  ± 0.106). The strongest
negative correlation occurred at the Baton Rouge, LA, site (-0.4762), while the highest positive
correlation occurred at the El Paso, TX, site (0.108).

       Statistical significance of the correlation between the dew point temperature and visibility
with the measured hydrocarbon concentrations at the 95 percent confidence interval was also
calculated  across all 12 sites.  As Table 5-1 shows, only the visibility parameter was statistically
significant, suggesting that as the visibility decreases (or haziness increases), the ambient
concentrations of hydrocarbons decrease.

5.3    Annual Variations
       Table 5-2 presents average concentrations of program-wide prevalent hydrocarbons at
each of the 12 monitoring stations for the  1994 through 1998 UATMPs. In very few cases are
consistent positive or negative trends seen for the concentration of  a specific hydrocarbon
compound across the entire 4 year period (e.g., an annual decrease  in the concentration of a
compound in each year).  Readers should note that changes in concentrations can result from
shifting prevailing winds and might not necessarily indicate  increases or decreases in emissions.
In general, concentrations of total program-wide prevalent hydrocarbons have decreased annually
since 1995.
                                           5-6

-------
5.4    Spatial Variations
       To provide a sense of how overall levels of hydrocarbons varied among the UATMP
monitoring locations, Figure 5-2 compares the geometric means of the sums of the program-wide
prevalent hydrocarbon concentrations for each monitoring location.  These data are provided for
comparison purposes only and should not be confused with concentrations of total nonmethane
organic compounds, which is another common air quality measurement.

       Figure 5-2 clearly indicates that levels of the program-wide prevalent hydrocarbons at El
Paso, Texas (EPTX), were significantly higher than the levels measured at any of the other
monitoring stations. The figure also indicates that levels of the most program-wide prevalent
hydrocarbons were lowest at Underbill, Vermont (UNVT), and Beulah, North Dakota (BUND).

5.5    The  Impact of Motor Vehicle Emissions on Spatial Variations
       Motor vehicles significantly contribute to air pollution in urban environments. Pollutants
found in motor vehicle exhaust generally result from incomplete combustion of vehicle fuels.
Although modern vehicles and, more recently, vehicle fuels have been engineered to minimize air
emissions, all motor vehicles with internal combustion engines emit a wide range of chemical
pollutants. The magnitude of these emissions in urban areas primarily depends on the volume of
traffic, while the chemical profile of these emissions depends more on vehicle design and fuel
content. This report uses two parameters to evaluate the impact of motor vehicle emissions on
ambient air quality:
                                           5-7

-------
       Car ownership data; and
       Motor vehicle emissions profiles.

       5.5.1   Car Ownership Data
       As an indicator of motor vehicle emissions near the UATMP monitoring locations,
Table 5-3 presents estimates of the number of cars owned by residents within 10 miles of each
monitoring location.  The total number of cars owned within a 10-mile radius was estimated
based on a ratio of 0.74 cars per person (U.S. population of 260,000,000 and total  number of cars
in U.S. of 193,400,0000).

       For purposes of comparison, both car ownership data and the observed levels of total
program-wide prevalent hydrocarbons are presented in Table 5-3, ranked in descending order.
The data in the  table indicate a positive linear correlation between car ownership data and
ambient air concentrations of hydrocarbons. However, readers should keep in mind other factors
that might impact the reliability of car ownership data as an indicator of ambient air monitoring
data results:
       Estimates of higher car ownership within a 10-mile radius do not necessarily imply
       increased motor vehicle use in the immediate vicinity of a monitoring location.
       Conversely, sparsely populated regions often contain heavily traveled roadways.
       Emissions sources in the area other than motor vehicles may significantly affect levels of
       hydrocarbons in the ambient air.
       5.5.2  Motor Vehicles Emissions Profiles
       The magnitude of emissions from motor vehicles generally depends on the volume of
traffic in urban areas, but the composition of these emissions depends more on vehicle design.
Because the distribution of vehicle design (i.e., the relative number of cars of different styles) is
probably quite similar from one urban area to the next, the composition of air pollution resulting
from motor vehicle emissions is not expected to exhibit significant spatial variations. In support
                                           5-8

-------
of this hypothesis, previous air monitoring studies have observed relatively constant
compositions of ambient air samples collected along heavily traveled urban roadways (Conner
et al., 1995).  Roadside studies have found particularly consistent proportions of four
hydrocarbons (benzene, toluene, ethylbenzene, and the xylene isomers - the "BTEX"
compounds) both in motor vehicle exhaust and in ambient air near roadways.

       To examine the impact of motor vehicle emissions on air quality at the 1998 UATMP
monitoring sites, Figure 5-3 compares concentration ratios for the BTEX compounds measured
during the 1998 UATMP to the ratios reported in a roadside study (Conner et al., 1995). This
comparison provides a qualitative depiction of how greatly motor vehicle emissions affect air
quality at the UATMP monitoring locations: the more similar the concentration ratios at a
particular monitoring location are to those of the roadside study, the more likely that motor
vehicle emissions impact ambient levels of hydrocarbons at that location.

       As Figure 5-3 shows, the concentration ratios for BTEX compounds measured at every
UATMP monitoring station bear some resemblance to the ratios reported in the roadside study.
The BTEX ratio for the Baton Rouge monitoring location is most similar to the roadside study
profile. For all monitoring locations except El Paso, Texas, the toluene:ethylbenzene ratio is
clearly the largest value of the four ratios and the xylene:ethylbenzene ratio is clearly the smallest
value of the ratios. This observation suggests, though certainly does not prove, that emissions
from motor vehicles significantly affect levels of hydrocarbons in urban ambient air.  It should be
noted that BTEX concentration ratios for El Paso, Texas deviate from the roadside study profile.
This deviation indicates that emissions from sources other than motor vehicles in these locations
may have a strong influence on local air quality.

5.6    The Impact of Industrial Emissions on Spatial Variations
       For purposes of comparison, Table 5-3 summarizes emissions data for each monitoring
location, and ranks each data set with the highest value assigned the rank of one. For each
monitoring location, Table 5-3 includes:
                                           5-9

-------
•      The geometric mean of the sum of the program-wide prevalent hydrocarbon
       concentrations for each sampling event.

•      The sum of emissions of 6 of the 7 program-wide prevalent hydrocarbons detected during
       the 1998 UATMP reported to TRI in 1997 by facilities within 10 miles of the 1998
       UATMP monitoring locations. The table does not account for emissions of acetylene
       because industries are not required to disclose releases of this compound to TRI.

       Total emissions reported to TRI in 1997 by facilities within 10 miles of the 1998 UATMP
       monitoring locations.

       As the table shows, the TRI emissions ranks for the 12 sites were not entirely consistent
with the respective rank of the total ambient air concentration of the program-wide prevalent

hydrocarbons.  For instance:


•      The Baton Rouge, LA, monitoring site had high concentrations of program-wide
       prevalent hydrocarbons, high emissions of program-wide prevalent hydrocarbons reported
       to TRI, and high emissions of total hydrocarbons reported to TRI.

•      Some monitoring locations (e.g., Burlington and Rutland, VT and El Paso, TX) had
       relatively high concentrations of the program-wide prevalent hydrocarbons, but had
       relatively low levels of both program-wide prevalent hydrocarbon and total industrial
       emissions reported to TRI.

•      Other monitoring locations (e.g., Hahnville and Garyville, LA) had relatively low
       concentrations of hydrocarbons, but had relatively high levels of emissions reported to
       TRI.

       To examine the TRI emissions data more closely, Table 5-4 compares  the reported air
releases for the individual program-wide prevalent hydrocarbons (excluding acetylene) to the
corresponding geometric mean concentrations measured during the 1998 UATMP. For ease of
interpretation, Table 5-4 lists the monitoring locations in order of decreasing geometric mean
concentration for each compound. Readers should keep in mind that the concentrations of these
compounds are quite low in all cases, 0.20 to 3 ppbv, and conclusions regarding spatial variation
should be made cautiously.
                                         5-10

-------
       The El Paso, TX, monitoring site reported the highest concentrations for all three of the
hydrocarbon compounds presented in Table 5-4.  However, low to moderate levels of these
compounds are reported to TRI by facilities within 10 miles of the facilities. The Texarkana,
AR, Beulah, ND, and Underhill, VT, sites consistently reported low pollutant concentrations and
no program-wide prevalent hydrocarbon emissions were reported to TRI by facilities with  10
miles of these sites.
                                          5-11

      a This value was calculated as follows: (1) For each monitoring site, for each sampling event, the concentrations of the program-wide prevalent hydrocarbons
      were summed.  (2) For each monitoring site, the geometric mean of the sampling event totals was calculated.
      'Industrial emissions were calculated from emissions data for TRI reporting year 1997 (TRI, 1997). The emissions reported in the table are the total air releases
      of the hydrocarbons found to be program-wide prevalent in the 1998 UATMP. Acetylene was not reportable to TRI in 1997.
      c Industrial emissions were calculated from emissions data for TRI reporting year 1997 (TRI, 1997).

6.0    Data Interpretation: Halogenated Hydrocarbons
       Halogenated hydrocarbons are organic compounds that contain carbon, hydrogen, and
halogens—the chemical group that includes chlorine, bromine, and fluorine. Most halogenated
hydrocarbons are used for industrial purposes and as solvents, though some are produced
naturally (Godish, 1997).  Once emitted to the air, many volatile halogenated hydrocarbons resist
photochemical breakdown and therefore persist in the atmosphere for relatively long periods of
time (Godish, 1997; Ramamoorthy and Ramamoorthy, 1997). These compounds can cause
chronic health effects as well as contribute to the formation of tropospheric ozone. Like
hydrocarbons, only the halogenated hydrocarbons with lower molecular weights are volatile, and
the sampling and analytical methods used in the 1998 UATMP measure a subset of 37 of these
volatile compounds.

       The discussions in this chapter center on the general trends observed for the nine
program-wide prevalent halogenated hydrocarbons and consider halogenated hydrocarbon
concentrations quantified at the 12 monitoring locations, with respect to:
       Correlations between concentrations of the program-wide prevalent halogenated
       hydrocarbons and concentrations of other compounds measured at the same time at the
       same monitoring location;
       Correlations between concentrations of the program-wide prevalent halogenated
       hydrocarbons and temperature;
       Correlations between concentrations of the program-wide prevalent halogenated
       hydrocarbons and meteorological parameters;
       Temporal (annual) variations in halogenated hydrocarbon concentrations measured during
       the 1994 through 1998 UATMPs;
       Spatial variations in halogenated hydrocarbon concentrations measured during the 1998
       UATMP; and
       Relationship between spatial variations in halogenated hydrocarbon concentrations
       measured during the 1998 UATMP and estimates of industrial emissions.
                                          6-1

-------
6.1    Correlations Between Concentrations of Different Compounds
       From the ambient air monitoring data collected for each sampling event at each site,
Pearson correlation coefficients were calculated to compare concentrations of the program-wide
prevalent compounds from the four groups of chemicals studied in the 1998 UATMP
(i.e., hydrocarbons, halogenated hydrocarbons, polar compounds, and carbonyls). The following
discussion summarizes the calculated correlations.

       6.1.1   Correlations Between Halogenated Hydrocarbons and Hydrocarbons
       Figure 6-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent halogenated hydrocarbons and
program-wide prevalent hydrocarbons.

       As the distribution of Pearson correlation coefficients in Figure 6-1 shows, ambient air
concentrations of the program-wide prevalent halogenated hydrocarbons measured during the
1998 UATMP were weakly correlated with ambient air concentrations of the program-wide
prevalent hydrocarbons.  Approximately 25 percent of the correlation coefficients were between
+0.50 and +0.75, indicating a moderate positive correlation. Nearly 42 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation.  However, the
average correlation is statistically significant (0.250 ± 0.174) across the 12 sites.  These weak
correlations generally suggest that the factors that most strongly affect levels of halogenated
hydrocarbons in ambient air are different from the factors that affect ambient air concentrations of
hydrocarbons.
                                           6-2

-------
       6.1.2   Correlations Between Halogenated Hydrocarbons and Polar Compounds
       Figure 6-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent halogenated hydrocarbons and
program-wide prevalent polar compounds.

       As the distribution of Pearson correlation coefficients in Figure 6-1  shows, ambient air
concentrations of the program-wide prevalent halogenated hydrocarbons measured during the
1998 UATMP were very weakly correlated with ambient air concentrations of the program-wide
prevalent polar compounds.  Across all 12 sites, there was no statistical significance in the
correlations (0.146 ± 0.192). Less than 10 percent of the correlation coefficients were between
either +0.75 and+1, indicating few strong correlations. Nearly 58 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation. These weak
correlations generally suggest that the factors that most strongly affect levels of halogenated
hydrocarbons in ambient air are different from the factors that affect ambient air concentrations
of polar compounds.

       6.1.3   Correlations Between Halogenated Hydrocarbons and Carbonyls
       Figure 6-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent halogenated hydrocarbons and
program-wide prevalent carbonyls.

       The distribution of Pearson correlation coefficients in Figure 6-1 shows that ambient air
concentrations of the program-wide prevalent halogenated hydrocarbons measured during the
1998 UATMP were correlated with ambient air concentrations of the program-wide prevalent
carbonyls.  Across all 12 sites, there was  no statistical significance in the correlations (0.160 ±
0.175).  Less than 10 percent of the correlation coefficients were between +0.50 and +0.75,
indicating a moderate positive correlation. Approximately 42 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation. These weak
correlations generally suggest that the factors that most strongly affect levels of halogenated
                                           6-3

-------
hydrocarbons in ambient air are different from the factors that affect ambient air concentrations
of carbonyls.

6.2    Correlations Between Concentrations and Temperature

       6.2.1 Temperature
       According to Table 6-1, the program-wide prevalent halogenated hydrocarbons had
positive correlations with maximum, minimum, and average temperature across all twelve sites.
This observation would suggest that increasing temperature would relate to increasing measured
concentration of halogenated hydrocarbons. The highest positive correlations of halogenated
hydrocarbon concentration with maximum, minimum, and average temperature occurred at the
Hahnville, LA, site (0.570, 0.686, and 0.596, respectively).  The Brattleboro, VT, site had the
strongest negative correlation of halogenated hydrocarbon concentration with minimum
temperature (-0.089).

       Statistical significance of the correlation between the temperature parameters and the
measured halogenated hydrocarbon concentrations at the 95 percent confidence interval was also
calculated for each of the sites.  As Table 6-1 shows,  all of these correlations were statistically
significant.

       6.2.2   Wind and Sea Level Pressure Information
       According to Table 6-1, the program-wide prevalent halogenated hydrocarbons had a
negative correlation with the wind speed across the 12 sites. This observation would suggest that
high wind speeds tend to decrease the measured concentration of halogenated hydrocarbons. The
correlation between sea level pressure and the measured halogenated hydrocarbon concentration
was negative (-0.078 ± 0.100).

       Statistical significance of the correlation between the wind speed and sea level pressure
and the measured halogenated hydrocarbon concentrations at the 95 percent confidence interval
                                           6-4

-------
was also calculated for each of the sites. As Table 6-1 shows, only the correlation with the wind
speed was statistically significant. This observation suggests that increasing wind speeds reduce
the concentrations of the halogenated hydrocarbons, either by dilution or by removing the
compounds from the area where the measurements are being made.

       6.2.3   Dew Point Temperature and Visibility
       According to Table 6-1, the program-wide prevalent halogenated hydrocarbons generally
had positive correlations with both the dew point temperature and visibility. The highest positive
correlation of halogenated hydrocarbon concentration with dew point temperature and visibility
occurred at the Hahnville, LA, site (0.668) and the Baton Rouge (0.281) sites, respectively. The
strongest negative correlations for these two parameters occurred at the Texarkana, AR, site
(-0.003) and Camden, NJ (-0.223) sites, respectively.

       Statistical significance of the correlation between the dew point temperature and visibility
and the measured halogenated hydrocarbon concentrations at the 95 percent confidence interval
was also calculated for each of the sites. As Table 6-1 shows, only the dew point temperature
exhibits a statistically significant positive correlation with measured halogenated hydrocarbon
concentration. This observation would suggest that halogenated hydrocarbons may increase with
increasing moisture.

6.3    Annual Variations
       Table 6-2 presents average concentrations of program-wide prevalent halogenated
hydrocarbons at each of the 12 monitoring stations for the 1994 through 1998  UATMPs.
Overall, there is a general pattern of decreased concentrations of halogenated hydrocarbons from
1995 through 1998.

       Readers should note that changes in concentrations can result from shifting prevailing
winds and might not necessarily indicate increases or decreases in emissions.  In addition, readers
                                           6-5

-------
should keep in mind that the concentrations of these compounds are quite low, generally less than
0.40 ppbv, and conclusions regarding annual variation should be made cautiously.

6.4    Spatial Variations
       To provide a sense of how overall levels of halogenated hydrocarbons varied among the
UATMP monitoring locations, Figure 6-2, presents the geometric means of the sampling event
sums of the program-wide prevalent halogenated hydrocarbon concentrations for each monitoring
location. Unlike the concentration range seen for the hydrocarbons, little variation is
demonstrated for the concentrations and no strong trend is exhibited in geometric means data
presented in Figure 6-2. In addition, the geometric means for the halogenated compounds are
considerably lower (maximum of 3.2 ppbv) at all locations in comparison to the geometric means
for hydrocarbons and carbonyls.

6.5    The Impact of Motor Vehicle Emissions on Spatial Variations
       Motor vehicles emit significantly greater quantities of hydrocarbons than they do
halogenated hydrocarbons. As a result, motor vehicle emissions generally do not correlate well
with airborne levels of halogenated hydrocarbons.

       For purposes of comparison, both car ownership data and the observed levels of total
program-wide prevalent halogenated hydrocarbons are presented in Table 6-3, each ranked in
descending order.  The data in this table show no relationship between car ownership as an
indicator of motor vehicle emissions and concentrations of halogenated hydrocarbons in ambient
air.
                                          6-6

-------
6.6    The Impact of Industrial Emissions on Spatial Variations
       For purposes of comparison, Table 6-3 summarizes emissions data for each monitoring
location and ranks each data set with the highest value assigned the rank of one. For each

monitoring location, Table 6-3 includes:
       The geometric mean of the sum of the program-wide prevalent halogenated hydrocarbon
       concentrations for each sampling event.

       The sum of emissions of the 9 program-wide prevalent halogenated hydrocarbons
       detected during the 1998 UATMP reported to TRI in 1997 by facilities within 10 miles of
       the 1998 UATMP monitoring locations.

       Total emissions reported to TRI in 1997 by facilities within 10 miles of the 1998 UATMP
       monitoring locations.
       As the table shows, the TRI emissions ranks for the 12 sites were fairly consistent with

the respective ranks of the total ambient air concentrations of the program-wide prevalent
halogenated hydrocarbons. Unique trends in the data presented in Table 6-3 include:
       Two monitoring locations (i.e., Hahnville and Garyville, LA) had the highest
       concentrations of halogenated hydrocarbons and among the highest emissions for total
       industrial emissions reported to TRI. A distinct difference in the levels of industrial
       emissions of program-wide prevalent hydrocarbons reported to TRI is  seen between these
       sites, despite the similarity in total TRI emissions.  These two facilities are located
       within 13 miles of each other. Many of the facilities with 10 miles of the Hahnville site
       are within 15 miles of the Garyville site and may impact the air quality at the Garyville
       monitoring station. The difference in the industrial emissions of program-wide prevalent
       halogenated hydrocarbons reported to TRI is due to greater than 30,000 pounds of
       chloromethane reported by the one facility that  is within 10 miles of the Hahnville site,
       but not within  10 miles of the Garyville site.

       One monitoring location (i.e., Texarkana, AR) had among the lowest concentrations of
       the program-wide prevalent  hydrocarbons, but had relatively high  levels of total industrial
       emissions reported to TRI, and moderate emissions of program-wide prevalent
       hydrocarbons.
                                          6-7

-------
       To examine the TRI emissions data more closely, Table 6-4 compares the reported air

releases for the individual program wide prevalent hydrocarbons (excluding acetylene) to the
corresponding geometric mean concentrations measured during the 1998 UATMP. For ease of
interpretation, Table 6-4 lists the monitoring locations in order of decreasing geometric mean
concentration for each compound. In general, the data in Table 6-4 indicate that industrial
emissions are not a dominating factor influencing levels of halogenated hydrocarbons in ambient
air. Readers should keep in mind that the concentrations of these compounds are quite low in
most cases, generally less than 1 ppbv, and conclusions regarding spatial variation should be
made cautiously.


       Only two compounds, chloromethane and trichlorotrifluoroethane, appear to exhibit a
positive relationship between concentrations of pollutant detected at the monitoring site and
industrial emissions.  In each case, the site with the highest reported concentration is also the site
with the highest reported industrial emissions. However, it should be noted that:
       While the Baton Rouge, LA, site has the highest ambient concentration of
       trichlorotrifluoroethane and is the only monitoring site for which the pollutant was
       reported as an industrial emission, the levels of trichlorotrifluoroethane at Baton Rouge
       (geometric mean of 0.16 ppbv) are not significantly different from the emissions at
       Hahnville, LA (geometric mean of 0.13 ppbv).

       Hahnville and Baton Rouge, LA, have the highest geometric mean concentrations of
       chloromethane and are the only monitoring sites for which the pollutant was reported as
       an industrial emission.  However, the levels of chloromethane at Baton  Rouge and
       Hahnville are not significantly different from the emissions at the rest of the monitoring
       sites. In addition, Hahnville has the highest geometric mean concentrations of
       chloromethane (1.45 ppbv), but reported emissions of chloromethane are less than half
       the emissions reported for Baton Rouge (geometric mean concentration of chloromethane
       of 0.85 ppbv).

      ' This value was calculated as follows: (1) For each monitoring site, for each sampling event, the concentrations of the program-wide prevalent hydrocarbons
      were summed. (2) For each monitoring site, the geometric mean of the sampling event totals was calculated.
      b Industrial emissions were calculated from emissions data for TRI reporting year 1997 (TRI, 1997). The emissions reported are the total air releases of the
      halogenated hydrocarbons identified as program-wide prevalent for the 1998 UATMP.
      c Industrial emissions were calculated from emissions data for TRI reporting year 1997 (TRI, 1997).
      d The total number of cars owned within a 10-mile radius was estimated based on a ratio of 0.74 cars per person (U.S. population of 260,000,000 and total cars in
      U.S. of 193,400,000).  Information from "Statistical Abstract of the United States", 1999, and the internet link at http://link-usa.com/zipcode/pop.htm

7.0    Data Interpretation: Polar Compounds
       Polar compounds (i.e., oxygenated compounds such as methyl tert-butyl ether, methyl
ethyl ketone, etc.) were added to the UATMP analyte list that included the volatile halogenated
hydrocarbons and selected hydrocarbons because of the nation-wide use of these types of
compounds as gasoline additives and the toxicity of these gasoline additives. Because of the
prevalence of compounds characteristic of motor vehicle emissions, any compounds used as
gasoline additives would be expected to be correspondingly prevalent. Other polar compounds
such as acetonitrile were added to the analyte list because the compounds were observed at high
concentrations at one or more monitoring sites.

       The discussions in this chapter center on the general trends observed for the three
program-wide prevalent polar compounds and consider polar compound concentrations
quantified at the 12 monitoring locations, with respect to:
       Correlations between concentrations of the program-wide prevalent polar compounds and
       concentrations of other compounds measured at the same time at the same monitoring
       location;
•      Correlations between concentrations of the program-wide prevalent polar compounds and
       temperature;
•      Correlations between concentrations of the program-wide prevalent polar compounds and
       meteorological parameters.
•      Temporal (annual) variations in polar compound concentrations measured during the
       1994 through 1998 UATMPs;
•      Spatial variations in polar compound concentrations measured during the 1998 UATMP;
       and
•      Relationship between spatial variations in polar compound concentrations measured
       during the 1998 UATMP and estimates based on the estimation of industrial emissions.
                                          7-1

7.1    Correlations Between Concentrations of Different Compounds
       From the ambient air monitoring data collected for each sampling event at each site,
Pearson correlation coefficients were calculated to compare concentrations of the program-wide
prevalent compounds from the four groups of chemicals studied in the 1998 UATMP
(i.e., hydrocarbons, halogenated hydrocarbons,  polar compounds, and carbonyls).  The following
discussion summarizes the calculated correlations.

       7.1.1   Correlations Between Hydrocarbons and Polar Compounds
       Figure 7-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent hydrocarbons and program-wide
prevalent polar compounds.

       As the distribution of Pearson correlation coefficients in Figure 7-1 shows, ambient air
concentrations of the program-wide prevalent hydrocarbons measured during the 1998 UATMP
were very weakly correlated with ambient air concentrations of the program-wide prevalent polar
compounds. Approximately 16 percent of the correlation coefficients were between +0.50 and
+0.75, indicating a moderate positive correlation. Nearly 58 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation.  However, the
average correlation was statistically significant  across the 12 sites (0.199 ± 0.152). These weak
correlations generally suggest that the factors that most strongly affect levels of hydrocarbons in
ambient air are different from the factors that affect ambient air concentrations of polar
compounds.

       7.1.2   Correlations Between Halogenated Hydrocarbons and Polar Compounds
       Figure 7-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent halogenated hydrocarbons and
program-wide prevalent polar compounds.
                                          7-2

-------
       As the distribution of Pearson correlation coefficients in Figure 7-1 shows, ambient air
concentrations of the program-wide prevalent halogenated hydrocarbons measured during the
1998 UATMP were very weakly correlated with ambient air concentrations of the program-wide
prevalent polar compounds. Across all 12 sites, there was no statistical significance in the
correlations (0.146 ± 0.192). Less than 10 percent of the correlation coefficients were between
either +0.75 and +1, indicating few strong correlations. Nearly 58 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation. These weak
correlations generally suggest that the factors that most strongly affect levels of halogenated
hydrocarbons in ambient air are different from the factors that affect ambient air concentrations
of polar compounds.

       7.1.3   Correlations Between Carbonyls and Polar Compounds
       Figure 7-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for pairs of the program-wide prevalent polar compounds and
program-wide prevalent carbonyls.

       The distribution of Pearson correlation coefficients in Figure 7-1  indicates a weak
correlation between ambient air concentrations of the program-wide prevalent carbonyls
measured during the 1998 UATMP and those of program-wide prevalent polar compounds.
Approximately 25 percent of the correlation coefficients were between -0.25 and -0.50,
indicating a moderate negative correlation.  Approximately 58 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation.

7.2    Correlations Between Concentrations and Temperature

       7.2.1   Temperature
       According to Table 7-1, the program-wide prevalent polar compounds had a positive
correlation for maximum temperature and negative correlations for minimum and average
temperature across all 12 sites.  The highest positive correlations of polar compound
                                           7-3

-------
concentrations with maximum and average temperature occurred at the Little Rock, AR, site
(0.401 and 0.366, respectively), while the Burlington, VT, site had the highest positive
correlation for minimum temperature (0.321). The Baton Rouge, LA, site had the strongest
negative correlation of polar compound concentration with all three temperature parameters
(-0.478, -0.326, and -0.406, respectively).

       Statistical significance of the correlation between the temperature parameters and the
measured polar compound concentrations at the 95 percent confidence interval was also
calculated for each of the sites.  As Table 7-1 shows, none of these correlations were statistically
significant.

       7.2.2   Wind and Sea Level Pressure Information
       According to Table 7-1, the program-wide prevalent polar compounds had positive
correlations with the wind speed across the 12 sites. The highest positive correlation of polar
hydrocarbon concentration with the wind speed occurred at the Rutland, VT, site (-0.524) while
the Texarkana, AR, site  had the strongest negative correlation with the wind speed (-0.516).

       The correlation between sea level pressure and polar compound concentrations was
negative across the 12 sites.  The Burlington, VT, site had the strongest negative correlation
(-0.462), while the Beulah, ND, site had the highest positive  correlation (0.271).

       Statistical significance of the correlation between the wind speed and sea level pressure
with the measured polar compound concentrations at the 95 percent confidence interval was also
calculated across the 12 sites. As Table 7-1 shows,  neither of these correlations  were statistically
significant.

       7.2.3   Dew Point Temperature and Visibility
       According to Table 7-1, the program-wide prevalent polar compounds had a positive
correlation with the dew point temperature.  The highest positive correlation of  polar compound
                                           7-4

-------
concentrations with the dew point temperature occurred at the Camden, NJ, site (0.388), while
the strongest negative correlation for this parameter occurred at the Garryville, LA, site (-0.369).

       Visibility showed a negative correlation with the polar compound concentrations across
the 12 sites. The strongest negative correlation occurred at the Texarkana, AR, site (-0.518),
while the highest positive correlation occurred at the Garyville, LA, site (0.134).

       Statistical significance of the correlation between the dew point temperature and the
visibility with the measured polar compound concentrations at the 95 percent confidence interval
was also calculated across the 12 sites.  As Table 7-1 shows, only the visibility correlation was
statistically significant, suggesting that as the visibility decreases (indicating increased haziness)
the polar compound concentrations increase.

7.3    Annual Variations
       This section briefly describes the annual variation in ambient air concentrations of the
program-wide prevalent polar compounds. Readers should note that changes in concentrations
can result from shifting prevailing winds and might not necessarily indicate increases or
decreases in emissions. Table 7-2 presents average concentrations of program-wide prevalent
polar compounds at each of the 12 monitoring stations for the 1997 and 1998 UATMPs. These
data illustrate the following general trends:
       With the exception of the Baton Rouge, LA, monitoring site, acetonitrile concentrations
       are lower in 1998 than in 1997. It should be noted that the Baton Rouge, LA, acetonitrile
       concentrations are orders of magnitude greater than at any other monitoring site.
       With the exception of the Baton Rouge and Garyville, LA, monitoring sites, methyl ethyl
       ketone concentrations are higher in 1998 than in 1997. Readers should keep in mind that
       the concentrations of this compound are quite low, generally less than 1 ppbv, and
       conclusions regarding annual variation should be made cautiously.
                                           7-5

-------
7.4    Spatial Variations
       To provide a sense of how overall levels of polar compounds varied among the UATMP
monitoring locations, Figure 7-2 presents the geometric means of the sampling event sums for
the program-wide prevalent polar compound concentrations at each monitoring location.  With
the exception of the large peak seen for the Baton Rouge, LA, site, little variation is
demonstrated for the concentrations and no strong trend is exhibited in geometric means data
presented in Figure 7-2.  Aside from the Baton Rouge, LA, site,  the geometric means for the
polar compounds are considerably lower (maximum of 1.9 ppbv) at all locations in comparison
to the geometric means for hydrocarbons and carbonyls.

       The large peak seen for the Baton Rouge, LA, site is the result of very high
concentrations of acetonitrile in some of the samples. Considerable variation is seen in the levels
of acetonitrile at this monitoring site, with values  ranging from 110 ppbv to concentrations below
the method detection limit.

7.5    The Impact of Motor Vehicle Emissions on Spatial Variations
       For purposes of comparison, both car ownership data and the observed levels of total
program-wide prevalent polar compounds are presented in Table 7-3, each ranked in descending
order.  The data in this table indicate a possible correlation between car ownership as an indicator
of motor vehicle emissions and concentrations of  polar compounds in ambient air, but exceptions
are also seen:
       Concentrations of program-wide prevalent polar compounds were lowest at the Beulah,
       ND, monitoring site.  This is also the site with the lowest total number of cars.
       Concentrations of program-wide prevalent polar compounds were highest at the Baton
       Rouge, LA, monitoring site. This site has the third highest total number of cars.
       Conversely, the Texarkana, AR, site has the second highest concentrations of program-
       wide prevalent polar compounds, but ranks in middle level for number of cars.
                                          7-6

-------
7.6    The Impact of Industrial Emissions on Spatial Variations
       For purposes of comparison, Table 7-3 summarizes emissions data for each monitoring
location, and ranks each data set with the highest value assigned the rank of one.  For each

monitoring location, Table 7-3 includes:
       The geometric mean of the sum of the program-wide prevalent polar compound
       concentrations for each sampling event.

       The sum of emissions for 8 of the 9 program-wide prevalent polar compounds detected
       during the 1998 UATMP, as reported to TRI in 1997 by facilities within 10 miles of the
       1998 UATMP monitoring locations. The table does not account for emissions of
       bromoform because industries are not required to disclose releases of this compound to
       TRI.

       Total emissions reported to TRI in 1997 by facilities within 10 miles of the 1998 UATMP
       monitoring locations.
       As the table shows, the TRI emissions ranks for the 12 sites were very consistent with the

respective rank of the total ambient air concentration of the program-wide prevalent polar

compounds. It should be noted that 6 of the 12 monitoring sites did not report any industrial

emissions of program-wide prevalent polar compounds. The relationship between ambient air
concentrations and industrial emissions is illustrated by the following:
       The Baton Rouge, LA, monitoring site reported the highest concentrations of program-
       wide prevalent polar compounds as well as the highest industrial emissions of both
       program-wide prevalent and total polar compounds.

       The Beulah, ND, and Underhill, VT, monitoring sites reported the lowest concentrations
       of program-wide prevalent polar compounds as well as the lowest industrial emissions of
       total polar compounds  and no industrial emissions of program-wide prevalent polar
       compounds.
To examine the TRI emissions data more closely, Table 7-4 compares the reported air releases

for acetonitrile, methyl ethyl ketone (MEK), and methyl tert-buty] ether (MTBE) to the

corresponding geometric mean concentrations measured during the 1998  UATMP.  For ease of

                                          7-7

-------
interpretation, Table 7-4 lists the monitoring locations in order of decreasing geometric mean

concentration for each compound.  At first glance, it appears that there may be a relationship

between industrial emissions and ambient air concentrations, but it must be noted that:
       While the acetonitrile emissions at Baton Rouge are significantly higher than at any other
       site, higher levels of industrial emissions of acetonitrile are reported for the
       Hahnville, LA, monitoring location.

       While industrial emissions of MEK are reported for the monitoring sites with the two
       highest levels of MEK ambient air concentrations, significant levels of MEK are reported
       by industrial facilities near three other monitoring locations.

       Facilities within 10 miles of Baton Rouge, LA, report high levels of industrial emissions
       of MTBE, but concentrations of MTBE measured at Baton Rouge are near or below the
       detection limit.
                                           7-8

a This value was calculated as follows: (1) For each monitoring site, for each sampling event, the concentrations of the program-wide prevalent hydrocarbons
were summed.  (2) For each monitoring site, the geometric mean of the sampling event totals was calculated.
""Industrial emissions were calculated from emissions data for TRI reporting year 1997 (TRI, 1997).  The emissions reported are the total air releases of the polar
compounds identified as program-wide prevalent for the 1998 UATMP.

8.0    Data Interpretation: Carbonyls
       Carbonyls are organic compounds characterized by their composition of carbon,
hydrogen, and oxygen, and by the presence of at least one carbon-oxygen double bond.  Several
different factors are known to affect ambient air concentrations of carbonyls, but most notably:
       Combustion sources, motor vehicles, and various industrial processes that emit carbonyls
       directly to the atmosphere;

       Photochemical reactions that form carbonyls in the air, typically from airborne
       hydrocarbons; and

       Photochemical reactions that consume carbonyls in the air, generally by photolysis or by
       reaction with hydroxyl radicals (Seinfeld, 1986). .
       As noted in Section 2, the 1998 UATMP sampling and analytical methods measured

concentrations of 16 carbonyl compounds. The discussions in this chapter center on the general
trends observed for four program-wide prevalent carbonyls and consider carbonyl concentrations
quantified at the 12 monitoring locations, with respect to:
       Correlations between concentrations of the program-wide prevalent carbonyls and
       concentrations of other compounds measured at the same time at the same monitoring
       location;

       Correlations between concentrations of the program-wide prevalent carbonyls and
       temperature;

       Correlations between concentrations of the program-wide prevalent carbonyls and
       meteorological parameters;

       Temporal (annual) variations in carbonyl concentrations measured during the 1994
       through 1998 UATMPs;

       Spatial variations in carbonyl concentrations measured during the 1998 UATMP;

       Relationship between spatial variations in carbonyl concentrations measured during the
       1998 UATMP and estimates based on estimation of motor vehicle emissions; and
                                          8-1

different sources.

       8.1.2  Correlations Between Carbonyls and Halogenated Hydrocarbons
       Figure 8-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent carbonyls and program-wide
prevalent halogenated hydrocarbons.

       The distribution of Pearson correlation coefficients in Figure 8-1 shows that ambient air
concentrations of the program-wide prevalent halogenated hydrocarbons measured during the
1998 UATMP were correlated weakly with ambient air concentrations of the program-wide
prevalent carbonyls.  Across all 12 sites, there was no statistical significance in the correlations
(0.160 ± 0.175).  Less than 10 percent of the correlation coefficients were between +0.50 and
+0.75, indicating a moderate positive correlation.  Approximately 42 percent of the correlation
coefficients were between -0.25 and +0.25, indicating very weak or no correlation. These weak
correlations  generally suggest that the factors that most strongly affect levels of halogenated
hydrocarbons in  ambient air are different from the factors  that affect ambient air concentrations
of carbonyls.

       8.1.3  Correlations Between Carbonyls and Polar Compounds
       Figure 8-1 shows the distribution of Pearson correlation coefficients calculated from the
ambient air monitoring data for the program-wide prevalent carbonyls and program-wide
prevalent polar compounds.

       The distribution of Pearson correlation coefficients in Figure 8-1 indicates a weak
correlation between ambient air concentrations of the program-wide prevalent carbonyls
measured during the 1998 UATMP and those of program-wide prevalent polar compounds.
Approximately 25  percent of the correlation coefficients were between -0.25 and -0.50,
indicating a moderate negative correlation. Approximately 58 percent of the correlation
                                           8-3

-------
coefficients were between -0.25 and +0.25, indicating very weak or no correlation. These weak
correlations generally suggest that the factors that most strongly affect levels of polar compounds
in ambient air are different from the factors that affect ambient air concentrations of carbonyls.
8.2    Correlations Between Concentrations and Meteorological Parameters

       8.2.1   Temperature
       According to Table 8-1, the program-wide prevalent carbonyls had positive correlations
with maximum, minimum, and average temperature across all twelve sites. This observation
would suggest that increasing temperature would relateto increasing measured concentration of
carbonyls.  The highest positive correlations of carbonyl concentrations with these
meteorological parameters all occurred at the Beulah, ND, site (0.681, 0.618, and 0.698,
respectively).  The Hahnville, LA, site had the strongest negative correlation of carbonyl
concentrations with the three temperature parameters (-0.417, -0.484, -0.419, respectively).

       Statistical significance of the correlation between the temperature parameters and the
measured carbonyl concentrations at the 95 percent confidence interval was also calculated
across the 12 sites.  As Table 8-1 shows, all of these correlations were statistically significant,
suggesting that air temperature is a key component in the measured carbonyl concentrations
tendency.

       8.2.2   Wind and Sea Level Pressure Information
       According to Table 8-1, the program-wide prevalent carbonyls had a negative correlation
with wind speed across the 12 sites.  The Baton Rouge, LA, site had the strongest negative
correlation (0.494). This observation would suggest that slow-moving air tends to increase the
measured concentrations of carbonyls. The strongest negative correlation of carbonyl
concentration with the sea level pressure occurred at the Beulah, ND, site  (-0.344) while the
Hahnville,  LA, site had the highest positive correlation (0.568).
                                           8-4

-------
       Statistical significance of the correlation between the wind speed and sea level pressure
with the measured carbonyl concentrations at the 95 percent confidence interval was also
calculated for each of the sites.  As Table 8-1 shows, only the correlation with wind speed was
statistically significant.  This observation suggests that increasing wind speeds reduce the
concentrations of the carbonyls, either by dilution or by removing the compounds from the area
where the measurements are being made.

       8.2.3   Dew Point Temperature and Visibility
       According to Table 8-1, the program-wide prevalent carbonyls generally had positive
correlations with both the dew point temperature and visibility. The highest positive correlation
of carbonyl concentration with the dew point temperature and the visibility occurred at the
Beulah, ND, site (0.643) and the Texarkana, AR, (0.349) site.  The Hahnville site had the
strongest negative correlations for both parameters (-0.457 and -0.551, respectively).

       Statistical significance of the correlation between these parameters and the measured
carbonyl concentrations at the 95 percent confidence interval was also calculated for each of the
sites. As Table 8-1 shows, only the dew point temperature was statistically significant, which
suggests that carbonyl concentrations may increase with increasing moisture.

8.3    Annual Variations
       This section briefly describes the annual variation in ambient air concentrations of the
program-wide prevalent carbonyls. Readers should note  that changes in concentrations can result
from shifting prevailing winds and might not necessarily indicate increases or decreases in
emissions. Table 8-2 presents average concentrations of program-wide prevalent carbonyls at
each of the 12 monitoring stations for the 1994 through 1998 UATMPs. These data illustrate the
following general trends:
       With only a few exceptions, the concentrations of acetaldehyde and formaldehyde have
       decreased every year at every monitoring site.
                                           8-5

-------
       No annual variation trend is apparent for acetone concentrations.
       With the exception of Camden, NJ, butyr/isobutyraldehyde concentrations have exhibited
       a trend of decreasing concentrations from 1995 through 1998.
8.4    Spatial Variations
       To provide a sense of how overall levels of polar compounds varied among the UATMP
monitoring locations, Figure 8-2 presents the geometric means of the sampling event sums for
the program-wide prevalent carbonyl concentrations at each monitoring location.

       To examine the TRI emissions data more closely, Table 8-3 compares the reported air
releases for the individual program-wide prevalent carbonyls (excluding acetone) to the
corresponding geometric mean concentrations measured during the 1998 UATMP. For ease of
interpretation, Table 8-3 lists the monitoring locations in order of decreasing geometric mean
concentration for each compound. No clear relationship between industrial emissions and
ambient air concentrations of carbonyls is demonstrated by the data presented in Table 8-3.

8.5    The Impact of Motor Vehicle Emissions on Spatial Variations
       Motor vehicles are thought to contribute to variations in carbonyl concentrations in
ambient air.  This report uses two parameters to evaluate the impact of motor vehicle emissions
on ambient air quality:

•      Car ownership data; and
•      Motor vehicle emissions profiles.

       8.5.1  Car Ownership Data
       As an indicator of motor vehicle emissions near the UATMP monitoring locations,
Table 8-4 presents estimates of the number of cars owned by residents within 10 miles of each
monitoring location.  For purposes of comparison, both car ownership data and the observed
levels of total program-wide prevalent carbonyls are presented in Table 8-4, ranked in

                                          8-6

-------
descending order. The data in the table indicate some correlation between car ownership data
and ambient air concentrations of carbonyls:
       The monitoring sites at El Paso, TX, and Camden, NJ, reported the highest concentrations
       of program-wide prevalent carbonyls and also have the highest numbers of cars within
       10 miles of the sites.
       The Beulah, ND, and Underhill, VT, sites report low concentrations of program-wide
       prevalent carbonyls and low numbers of cars within 10 miles of the sites. However, very
       little correlation can be seen between reported concentrations and car ownership at the
       remaining monitoring sites.
Readers should keep in mind other factors that might impact the reliability of car ownership data
as an indicator of ambient air monitoring data results:
       Higher car ownership within a 10-mile radius does not necessarily imply increased motor
       vehicle use in the immediate vicinity of a monitoring location. Conversely, sparsely
       populated regions often contain heavily traveled roadways.
       Emissions sources in the area other than motor vehicles may significantly affect levels of
       carbonyls in the ambient air.
       8.5.2   Motor Vehicles Emissions Profiles
       While the roadside study cited in Section 5 did not consider concentrations of carbonyls,
analysis of concentration ratios for selected carbonyls indicates that motor vehicle emissions
influence ambient levels of these compounds.  More specifically, if motor vehicles indeed
significantly affect ambient air concentrations of carbonyls, it would be expected that ratios of
concentrations of carbonyls to concentrations of any BTEX compound would be consistent
across monitoring locations.  As a test of this hypothesis, Figure 8-3 shows ratios between the
concentrations of four carbonyls—acrolein, benzaldehyde, and butyr/isobutyraldehyde—and
concentrations of m-,p-xylene for the 1998 UATMP monitoring locations. With the exception of
El Paso, TX, the ratios shown in Figure 8-3 are somewhat similar for the 12 monitoring
                                           8-7

-------
locations, which suggests that emissions from motor vehicles may affect airborne levels of these
three carbonyl compounds.

8.6    The Impact of Industrial Emissions on Spatial Variations
       For purposes of comparison, Table 8-4 summarizes emissions data for each monitoring
location and ranks each data set with the highest value assigned the rank of one. For each
monitoring location, Table 8-4 includes:
       The geometric mean of the sum of the program-wide prevalent carbonyl concentrations
       for each sampling event.
       The sum of emissions of 3 of the 4 program-wide prevalent carbonyls detected during the
       1998 UATMP (acetaldehyde, butyr/isobutyraldehyde, and formaldehyde) as reported to
       TRI in  1997 by facilities within 10 miles of the 1998 UATMP monitoring locations.  The
       table does not account for emissions of acetone because industries are not required to
       disclose releases of these compounds to TRI.
       Total emissions reported to TRI in 1997 by facilities within 10 miles of the 1998 UATMP
       monitoring  locations.
       As the table shows, the TRI emissions ranks for the 12 sites were not consistent with the
respective rank of the total ambient air concentration of the program-wide prevalent carbonyls. It
should be noted that 8 of the 12 monitoring sites did not report any industrial emissions of
program-wide prevalent carbonyl compounds. To examine the TRI emissions data more closely,
Table 8-4 compares the reported air releases for the individual program-wide prevalent carbonyls
(excluding acetone) to the corresponding geometric mean concentrations measured during the
1998 UATMP.  The weakness of the relationship between ambient air concentrations and
industrial emissions  is illustrated by the following:
       El Paso, TX, and Camden, NJ, reported the highest concentrations of the program-wide
       prevalent carbonyls, but had moderate levels of total industrial emissions reported to TRI
       and no industrial emissions of program-wide prevalent carbonyl compounds.
                                          8-8

-------
Other monitoring locations (e.g., Hahnville and Baton Rouge, LA) had relatively low
concentrations of carbonyls, but relatively high levels of emissions reported to TRI.
                                    8-9

      a This value was calculated as follows: (1) For each monitoring site, for each sampling event, the concentrations of the program-wide prevalent hydrocarbons
      were summed. (2) For each monitoring site, the geometric mean of the sampling event totals was calculated.
      bIndustrial emissions were calculated from emissions data for TRI reporting year 1997 (TRI, 1997). The emissions reported are the total air releases of the
      halogenated hydrocarbons identified as program-wide prevalent for the 1998 UATMP.  Acetone was not reportable to TRI in  1997.
      c Industrial emissions were calculated from emissions data for TRI reporting year 1997 (TRI, 1997).
      d The total number of cars owned within a 10-mile radius was estimated based on a ratio of 0.74 cars per person (U.S. population of 260,000,000 and total cars
      in U.S. of 193,400,000). Information from "Statistical Abstract of the United States", 1999, and the internet link at http://link-usa.com/zipcode/pop.htm

9.0    Data Quality
       This section evaluates how precisely and accurately ambient air concentrations were
measured during the 1998 UATMP.  As indicators of the reliability of experimental
measurements, both precision and accuracy should be considered when interpreting ambient air
monitoring results. In general, this section shows that the 1998 UATMP monitoring data are of a
known and high quality, particularly for the most program-wide prevalent compounds in urban
air.

9.1    Precision
       Precision refers to the mutual agreement between independent measurements performed
according to identical protocols and procedures. To quantify "sampling and analytical precision"
(Le., how precisely the sampling and analytical methods measure ambient air concentrations), the
section then compares concentrations measured during analysis of duplicate samples.
 ,4%pliedio ambient air mottitoring,data,,precwqk is a measurement lofrandom,hrors (5> ^ 
-------
       average concentration difference exceeds or nearly equals its central tendency, the
       analytical method may not be capable of precisely characterizing annual concentrations.
       Therefore, data interpretations for these compounds should be made with caution.

       Relative percent difference (RPD) expresses average concentration differences relative to
       the average concentrations detected during replicate analyses. The RPD is calculated as
       follows:

                                       IX,  - X2 I
                              RPD  = I  '  _  2 '  x 100                             (1)
                                           X
Where:
       Xl is the ambient air concentration of a given compound measured in one sample;
       X2 is the concentration of the same compound measured during replicate analysis; and
       X is the arithmetic mean of X} and X2.
       As Equation 1 shows, replicate analyses with low variability have lower RPDs (and better
precision), and replicate analyses with high variability have higher RPDs (and poorer precision).


       The following approach was employed to estimate how precisely the central laboratory

analyzed 1998 UATMP samples:
       RPDs and concentration differences were calculated for every replicate analysis performed
       during the program. In cases where compounds were not detected during replicate
       analyses, these parameters were not calculated.

       Second, to make an overall estimate of method precision, program-average RPDs and
       concentration absolute differences were calculated for each compound by averaging the
       values from the individual replicate analyses.
Tables 9-1 and 9-2 use both absolute average concentration differences and RPDs to characterize
the analytical precision representing all sites for the VOC and carbonyl measurements made

during the 1998 UATMP, respectively.
                                           9-2

-------
       Replicate analytical data show that laboratory VOC analysis precision was excellent.
With the exception of acetylene (average concentration difference of 0.18 ppbv), average
concentration difference in replicate analyses was less than or equal to 0.07 ppbv. The method
was most precise when measuring air concentrations for the most program-wide prevalent
compounds (i.e., compounds consistently found at levels exceeding their detection limits).  For
VOCs,  samples exhibit RPDs ranging from 1 percent to 17 percent.

       In terms of average concentration difference, the precision of the VOC analytical method
was fairly uniform across compounds, with few exceptions. The average concentration
difference during replicate analyses for most compounds was 0.03 ppbv or less, though acetylene
had a slightly greater concentration difference. The relatively high variability for acetylene
largely resulted from poor agreement in the replicate analysis of two sets of samples collected on
April 12, 1999, at El Paso, TX, and March 25, 1999, at Brattleboro, VT.  Disregarding these
samples, the average concentration difference for acetylene becomes 0.11 ppbv, rather than
0.18 ppbv.

       As Table 9-2 shows, laboratory analysis of carbonyl samples during the  1998 UATMP
was consistently more precise than analysis of VOC samples.  The RPD was less than 20 percent
for every carbonyl compound. With one exception, the average concentration differences
observed upon replicate analyses of carbonyls were less than or equal to 0.01 ppbv—
formaldehyde had average concentration differences of 0.02 ppbv.

       Accordingly, random errors during laboratory analysis had minimal impacts on the
carbonyl concentration data measured during the 1998 UATMP. Overall, replicate analyses of
both carbonyl and VOC samples suggest that the corresponding analytical methods consistently
measured each compound in air samples within a precision of 25 percent—a precision level well
within the UATMP data quality objectives (USEPA, 1988) and guidelines in the Compendium
Methods (USEPA, 1999).
                                          9-3

-------
       9.1.2   Sampling and Analytical Precision
       As the name implies, sampling and analytical precision quantifies random errors
associated not only with analyzing ambient air samples in the laboratory but also with collecting
the samples in the field. This form of precision is most easily evaluated by comparing
concentrations measured in duplicate samples collected off the same manifold.  During the 1998
UATMP, duplicate samples were collected on approximately 10 percent of the scheduled
sampling days, and most of these samples were analyzed in replicate. To calculate sampling and
analytical precision, data analysts first averaged the results from each replicate analysis (if
performed), then compared these average concentrations between the two samples in each
duplicate.  Tables 9-3 and 9-4 present average concentration differences and RPDs as estimates of
sampling and analytical precision for VOC and carbonyl measurements, respectively.  It should be
noted that Tables 9-1 and 9-2 are twice as high, representing the replicates of the duplicate
samples presented in Tables 9-3 and 9-4.

       According to the sampling and analytical data in Table 9-3, concentrations of VOCs
measured in duplicate samples during the 1998 UATMP were in excellent agreement. On
average, these concentrations differed by 0.10 ppbv or less for almost every compound detected
during the program. With the exception of acetonitrile (RPD of 69 percent), RPDs ranged from
1 percent to 35 percent.  The sampling and analytical precision data in Table 9-3 do not differ
significantly from the analytical precision data in Table 9-1. This similarity suggests that
limitations associated with laboratory analysis of the VOC samples during the 1998 UATMP
probably outweighed random errors associated with sampling procedures.

       Like the duplicate sampling results for VOCs, the duplicate sampling results for carbonyls
were highly precise. As the data in Table 9-4 show, every carbonyl compound had an RPD for
sampling and analytical precision less than or equal to 20 percent. For most compounds, the
sampling and analytical RPDs (see Table 9-4) were notably higher than the analytical precision
RPDs (see Table 9-2)—a trend that differs from the trend observed for VOCs. This observation
suggests that random errors associated with collecting air samples and random errors associated
                                           9-4

-------
with analyzing these samples both contributed significantly to overall imprecision in the carbonyl
sampling and analytical method.  Random sampling errors most likely resulted from trace amounts
of carbonyls contaminating the silica gel sampling cartridges before the scheduled sampling days.
As the estimates of sampling and analytical precision show, however, such sources of
contamination did not have significant impacts—not greater than 0.20 ppbv, on average—on the
carbonyl monitoring results.

       To summarize, duplicate sampling results indicate that the 1998 UATMP air quality
measurements generally have precision better than 25 percent—well within the UATMP data
quality objectives of 100 percent (USEPA, 1988).  This excellent measurement precision suggests
that the 1998 UATMP monitoring data offer a precise account of air quality at the selected
monitoring locations, especially for the most program-wide prevalent compounds. Although
random errors had very small impacts on measurement of the less program-wide prevalent
compounds, participating agencies should note that the central tendencies for these compounds
have nearly the same magnitude as the average concentration difference.  Therefore, central
tendency concentrations for these less program-wide prevalent compounds should be interpreted
with caution.

9.2    Accuracy
       Highly accurate air sampling and analytical methods can measure air concentrations in
very close agreement to actual ambient levels. Laboratories typically evaluate their accuracy by
analyzing external audit samples and comparing measured concentrations to the known
concentrations within the audits.

-------
       EPA/State participants provided three external audit samples for the 1998 UATMP. The

results are displayed on Table 9-5.  All acceptance criteria were met representing accurate

carbonyl analytical methods.


       The accuracy of the 1998 UATMP monitoring data can also be assessed qualitatively by
reviewing the accuracy of the monitoring methods and how they were implemented:
       The sampling and analytical methods used in the 1998 UATMP (i.e., Compendium
       Methods TO-11A and TO-15) have been approved by EPA for accurately measuring
       ambient levels of VOCs and carbonyls, respectively—an approval that is based on many
       years of research into the development of ambient air monitoring methodologies.

       When collecting and analyzing ambient air samples, all field sampling staff and
       laboratory analysts strictly followed quality control and quality assurance guidelines
       detailed in the respective monitoring methods.  This strict adherence to the well-
       documented sampling and analytical methods suggests, though certainly does not prove,
       that the 1998 UATMP monitoring data accurately represent ambient air quality.

10.0   Conclusions and Recommendations
       As indicated throughout this report, UATMP monitoring data offer a wealth of
information for evaluating trends and patterns in air quality and should ultimately help a wide
range of audiences understand the complex nature of urban air pollution. The following
discussion summarizes the main conclusions of this report and presents recommendations for
ongoing urban air monitoring efforts.


10.1   Conclusions
       Analyses of the 1998 UATMP monitoring data identified the following notable trends
and patterns in urban air pollution:
       Ambient air concentrations of hydrocarbons. Levels of airborne hydrocarbons were
       highest at the El Paso, TX, monitoring location and were lowest at the Underhill, VT, and
       Beulah, ND, monitoring locations. At most stations, emissions from motor vehicles and
       industrial sources appear to be important sources of hydrocarbons in ambient air.

       Ambient air concentrations of halogenated hydrocarbons.  Unlike the concentration
       range seen for the hydrocarbons, little variation is demonstrated for the concentrations
       and no strong trends are exhibited in  1998 UATMP halogenated hydrocarbons data.  No
       single factor was identified to explain air quality trends for this group of compounds.

       Ambient air concentrations of polar compounds.  Levels of airborne polar compounds
       were significantly higher at the Baton Rouge, LA, monitoring location while the
       remaining sites demonstrated little variation in polar compound concentrations.  The TRI
       emissions ranks for the  12 sites were  very consistent with the respective rank of the total
       ambient air concentration of the program-wide prevalent polar compounds. However,
       before drawing conclusions on the impact of industrial emissions  and ambient air
       concentrations, it should be noted that 6 of the 12 monitoring sites did not report any
       industrial emissions of program-wide prevalent polar compounds.

       Ambient air concentrations ofcarbonyls.  The UATMP monitoring data seem to  suggest
       that emissions from motor vehicles and photochemical reactions most strongly influence
       ambient air concentrations of carbonyls. The fact that ambient air concentrations of most
       carbonyls were positively correlated with temperature at most monitoring locations
       supported the hypothesis that photochemical reactions form carbonyls in ambient air.
       Although emissions data from facilities subject to the Toxic Release Inventory reporting
       requirements were quite inconsistent  with the observed spatial variations in
                                          10-1

-------
       concentrations of carbonyls, emissions from other industrial emissions sources may have
       contributed to the levels of carbonyls detected during the UATMP.
10.2   Recommendations
       In light of the lessons learned from the 1998 UATMP, a number of recommendations for
future ambient air monitoring are warranted:
       Continue to identify and implement improvements to the sampling and analytical
       methods. The improvements made to the analytical methods prior to the 1998 UATMP
       allowed for measurement of ambient air concentrations of 11 compounds that were not
       measured during previous programs. This improvement provides sponsoring agencies
       and a variety of interested parties with important information about air quality within
       their urban areas. Further research is encouraged to identify other method improvements
       that would allow the UATMP to characterize an even wider range of components in
       urban air pollution.

       Continue to strive to develop standard conventions for interpreting air monitoring data.
       The lack of consistent approaches to present and summarize ambient air monitoring data
       complicates or invalidates comparisons between different studies. Additional research
       should be conducted on the feasibility of establishing standard approaches for analyzing
       and reporting air monitoring data.

       Prepare a report characterizing all years of the UATMP and then update it yearly to
       better assess Trends and better understand the nature of U.S. urban air pollution.

       Consider more rigorous study of the impact of automobile emissions on ambient air
       quality using the complete UATMP data set. Because the UATMP has monitoring sites
       where years of continuous data are collected, a real opportunity exists to evaluate the
       importance and impact of automobile emissions on ambient air quality.  Suggested areas
       of study include:

       1.      Signature Compound Assessment.  Sample data from each site should be
              evaluated to look for signature compounds from mobile sources—that is, species
              typically associated  with only diesel and/or gasoline combustion. If the
              appropriate compounds are included in the UATMP speciation, sites lacking these
              compounds can be excluded from subsequent analyses. Desert Research Institute
              can provide a listing of potential signature compounds for mobile sources.

       2.      Micro-Climate Assessment. An assessment is needed of the immediate
              micro-climate for a representative "urban" and "rural" site, to determine a
              reasonable geographic radius of influence. It is absolutely critical to determine a

                                         10-2

-------
       rough estimate of the maximum radius of concern (Rmax) in order to know what
       sources need to be included in the characterization. A value for Rmax may be
       determined with relatively little effort using simple dispersion models, such as
       CALINZ4 for urban settings. In these models Rmax would be defined for non-
       reactive species such as CO or PM. Since most/all of the toxic compounds of
       concern have some level of reactivity, Rmax would actually be somewhat less.
       Therefore this method would provide a conservative estimate for Rmax.

3.     Identify Roadways of Concern. All roadways within a distance of Rmax should be
       identified for each site. Local area maps are best suited for this purpose.

4.     Estimate Traffic Volumes.  Data from the Highway Performance Monitoring
       System (HPMS) or the Bureau of Transportation  Statistics could be used  to
       estimate annual average traffic counts, as well as  the split between gasoline and
       diesel vehicles, for interstate and other major highways.  Local transportation
       planning organizations should be able to provide  counts for other urban roads.
       Rural non-interstate roads will probably require qualitative assessment, based on
       local resident estimates or short-duration observation. Note that obtaining the
       precise split between gasoline and diesel vehicles for any given roadway is a
       lower priority - national  default values could be used instead.

5.     Parking Lot Characterizations. Several monitoring locations are situated in or
       near parking lots. Evaporative emissions from parked gasoline vehicles could
       have a very significant impact on the monitors for these sites (depending upon the
       species of concern). Therefore we recommend determining the size of the lots in
       question in terms of number of spaces, as well as an average occupancy rate with
       total vehicles per day (to determine the number of start episodes). The occupancy
       rate should be a 24 hour annual average, and can  be established either through
       observation or local "experts" (e.g., the lot operator).  Also, it should be
       determined if the parking is covered or open—covered lots can significantly
       decrease crankcase temperatures and therefore lower evaporative emissions rates.

6.     Site-Specific Information. Additional information could be collected as needed to
       improve the quality of discussions  of air quality at specific sites. For example, for
       the El Paso site the UATMP could obtain a vehicle count split for US versus
       Mexican vehicles. Mexican vehicles have dramatically higher pollution rates and
       should be considered separately. This estimate could be obtained from the EPA
       or Texas Natural Resource Conservation Commission Border Liaisons.

Encourage continued participation in the UATMP.  Ongoing ambient air monitoring  at
fixed locations can provide insight into long-term trends  in urban air quality and  the
potential for urban air pollution to cause adverse health effects among the general
population.  Therefore, state and local agencies should be strongly encouraged either  to
develop and implement their own ambient air monitoring programs or to participate in
future UATMP monitoring efforts.

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
        observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text. As Section 3.1.3 discusses, central
        tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
        the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in
        italics represent overall site-specific prevalent compounds over 80% for frequency only.

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
        observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text. As Section 3.1.3 discusses, central
        tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
        the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in
        italics represent overall site-specific prevalent compounds over 80% for frequency only.

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one observation for each
        successful sampling day.  Program-wide prevalent compounds are presented in bold text.  As Section 3.1.3 discusses, central tendency concentrations for these

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
        observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text.  As Section 3.1.3 discusses, central
        tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
        the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in
        italics represent overall site-specific prevalent compounds over 80% for frequency only.

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
        observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text. As Section 3.1.3 discusses, central
        tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
        the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit.  Compounds listed in
        italics represent overall site-specific prevalent compounds over 80% for frequency only.

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
        observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text.  As Section 3.1.3 discusses, central
        tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
        the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in
        italics represent overall site-specific prevalent compounds over 80% for frequency only.

Notes:  Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
       observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text. As Section 3.1.3 discusses, central
       tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
       the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in
       italics represent overall site-specific prevalent compounds over 80% for frequency only.

Notes:  Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one observation for each
       successful sampling day. Program-wide prevalent compounds are presented in bold text. As Section 3.1.3 discusses, central tendency concentrations for these
       compounds should adequately represent long-term average concentrations, but the central tendency concentrations of the other compounds (in plain text) may be
       influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in italics represent overall site-specific prevalent compounds over
       80% for frequency only.

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
        observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text. As Section 3.1.3 discusses, central
        tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
        the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in
        italics represent overall site-specific prevalent compounds over 80% for frequency only.

Notes:   Summary statistics were calculated from a processed UATMP database, in which duplicate and replicate analyses were averaged to generate just one
        observation for each successful sampling day. Program-wide prevalent compounds are presented in bold text. As Section 3.1.3 discusses, central
        tendency concentrations for these compounds should adequately represent long-term average concentrations, but the central tendency concentrations of
        the other compounds (in plain text) may be influenced by the number of nondetects and the magnitude of the detection limit. Compounds listed in
        italics represent overall site-specific prevalent compounds over 80% for frequency only.
