1.0 SUMMARY
The Urban Air Toxics Monitoring Program (UATMP) was developed in 1987 by
the United States Environmental Protection Agency (U.S. EPA). The data
discussed in this report are from the analyses of samples collected during the
1990 program, from March 12, 1990, through February 23, 1991. During the 1990
program, 349 valid samples were collected in 6-liter (L) SUMMA®-treated
canisters. Four sites operated on different schedules. PEFL began sampling
on a 12-day schedule on February 10, 1990, and completed sampling on
February 23, 1991. TLOH began sampling on a 12-day schedule on April 5, 1990,
and completed sampling on December 13, 1990. BRLA and ORFL began sampling on
a 6-day sampling schedule on July 10, 1990, and completed sampling on
February 23, 1991. In every case for the 1990 UATMP, 24-hour samples were
obtained. These samples were collected from 12 sites in the United States
every 12 days, for a 24-hour collection period.
Table 1-1 lists the 1990 UATMP sites, along with the EPA Region, the
city in which the site is located, the Radian site code, and the Aerometric
Information Retrieval System (AIRS) number for the site. Nine of the 1990
sites also participated in the 1989 UATMP: CANJ, W1DC, W2DC, PEFL, C4IL, SAIL,
H1TX, BRLA, and W1KS.
UATMP canister samples were analyzed by a gas chromatograph/multiple
detector (GC/MD) system for 38 target organic compounds. The estimated
reporting limit for each of the 38 compounds is listed in Table 1-2. A
portion of the samples were also analyzed using a gas chromatograph/mass
spectrometer (GC/MS) as identification confirmation of the GC/MD results. The
estimated reporting limits for GC/MS are also listed in Table 1-2. These
estimated reporting limits were used as guidelines for precision and
quantitation only. Data were not excluded as a result of being below the
estimated reporting limit.
Table 1-3 presents summary statistics for the 1990 UATMP compound
identifications pooled for all the sites. Compound identifications and
quantitation included all cases in which identification criteria of retention
time and detector response ratio(s) were met, regardless of whether the
compound concentration was above or below the IDLs given in Table 1-2.

Benzene and toluene were identified in 100% of all the samples analyzed.
Carbon tetrachloride, 1,1,1-trichloroethane, ethylbenzene, m/p-xylene, and
styrene/o-xylene appeared in more than 98.9% of the samples, while
tetrachloroethylene was identified in 95.4% of the samples. The compound
identification frequency then dropped to 37.2% for p-dichlorobenzene, 35.2%
for trichloroethylene, and 30.4% for 1,3-butadiene. Vinyl chloride,
chloromethane, chloroethane, bromomethane, trans-l,2-dichloroethylene, 1,1-
dichloroethylene, chloroform, 1,2-dichloroethane, bromodichloromethane, trans-
1,3-dichloropropylene, n-octane/trans-1,3-dichloropropylene, cis-1,3-
dichloropropylene, dibromochloromethane, and 1,1,2,2-tetrachloroethane were
all identified in fewer than 10% of the samples.
The concentration ranges for target compounds identified, presented in
Table 1-3 as minima and maxima, ranged from 0.01 parts per billion by volume
(ppbv) to 515.49 ppbv. The maximum overall concentration of 515.49 ppbv was
for propylene. The maximum toluene concentration identified was 195.87 ppbv.
Eight compounds had maximum concentrations below 1.0 ppbv. Table 1-3 also
gives the medians, standard deviations, and three types of means, or averages,
for the target compounds. Column six of Table 1-3 lists the mean, or the
arithmetic average concentration, for those cases in which the compound was
identified. In the next column, the mean is calculated using one-half the
estimated reporting limit (Table 1-2) for samples in which the compound was
not identified. Finally, column eight of Table 1-3 gives the mean
concentrations, using zero for samples in which the compound was not
identified.
Although concentrations of air toxic pollutants have been shown to be
closer to lognormally distributed than to normally distributed1"3, arithmetic
averages (or means) have been used in this study. Means calculated in columns
seven and eight may be viewed as annual means, because the overall time period
of the data span about one year. Standard deviations given in Table 1-3 are
calculated using only the cases in which the compound was identified.
Analytical precision was measured in terms of percent coefficient of
variation (% CV) for repeated analyses of the same sample, and ranged from
2.23 to 29.00, with an average of 8.41. Sampling and analysis precision was

determined from analyses of duplicate samples. Percent CV for duplicates
ranged from 1.83 to 28.00, averaging 11.67.
Accuracy was determined from six external audits conducted by the
Quality Assurance Division (QAD) of the Atmospheric Research and Environmental
Assessment Laboratory (AREAL) of the USEPA. The average bias calculated for
each audited compound, ranged from -14.6% for ethylbenzene and bromomethane,
to 21.5% for methylene chloride. The overall average bias for all audited
compounds was -1.2 percent. Compound concentrations in the audit samples
ranged from about 2 to 8 ppbv.
About 15% of the UATMP samples were analyzed by GC/MS to confirm the
GC/MD analyses. Identifications were confirmed if both GC/MD and GC/MS
identified, or did not identify, the compound. GC/MS confirmed 89.4% of the
GC/MD results in the 1990 UATMP sample analyses.
The replicate and duplicate precision results, along with the audit bias
results for determining accuracy, reflect the quality of the data presented in
this report. The high percentage of GC/MS confirmed results indicates the
reliability and the representativeness of the compound identifications and
concentrations reported for UATMP.

2.0 INTRODUCTION
The UATMP was developed in 1987 to help state and local agencies
determine if an air toxics problem existed and, if one existed, what was the
nature and extent of it. From its origin, the UATMP has been regarded as a
screening program. That is, to assess the kinds of metals and organic
compounds, and their relative concentrations, which may be in urban
atmospheres. Because there may be hundreds of these substances in urban
environments, and because it is not possible to measure all of them in small
samples, the UATMP was deliberately structured to confine analysis of the
samples to a limited number of compounds which were of special concern to
health professionals.
Nonmethane organic compound (NMOC) and 3-hour air toxics monitoring
programs for 1990 are companion programs to UATMP. Sampling for the 1990 NMOC
and 3-hour air toxics monitoring programs began on June 2, 1990, and completed
on September 23, 1990. The results of the NMOC and 3-hour air toxics
monitoring programs are presented in a separate report.1
The UATMP consists of three analytical fractions: filter samples to be
analyzed for selected metals and benzo(a)pyrene, dinitrophenylhydrazine (DNPH)
cartridges samples for collection of carbonyl compounds, and canister samples
to be analyzed for 38 gaseous organic compounds. The DNPH cartridges are also
called "aldehyde cartridges," although both aldehydes (formaldehyde and
acetaldehyde) and a ketone (acetone) are quantitatively derivatized.
Throughout the remainder of this report, the DNPH cartridges will be referred
to as the aldehyde cartridges. The results from canister samples will be
presented and discussed in this report. The results from the aldehyde
cartridge samples will be presented in a separate report. Not all the sites
participated in the Hi-Vol filter collection part of the program.
The samples for each analytical fraction were collected simultaneously,
i.e., timers were programmed to start Hi:Vo1 filters, to start pumps that draw
air through cartridges that trap carbonyl compounds, and to open a valve to
start the canister sampling--all beginning at midnight on each scheduled day.
Samples were collected from March 12, 1990, through February 23, 1991, on a
12-day cycle, for the 1990 UATMP. Hi-Vol filter samples were sent by site
personnel directly to the U.S. EPA for analysis. Aldehyde cartridges and the
UATMP 6-L canisters were returned to Radian's Research Triangle Park (RTP),
-------
NC, laboratory. The aldehyde cartridges were transported to the U.S. EPA for
analysis, and the UATMP samples were analyzed by Radian.
Section 3.0 presents the descriptions of the UATMP field sampling
equipment, the GC/MD and GC/MS analytical equipment, the standards preparation
apparatus, and the canister cleanup system. Section 4.0 summarizes the
analytical results obtained for the 1990 UATMP, and Section 5.0 discusses the
data characterizations for the UATMP results. Section 6.0 gives
recommendations for future programs, and Section 7.0 provides the references

3.0 URBAN AIR TOXICS TECHNICAL NOTES
This section presents descriptions of the equipment and procedures used
in the 1990 UATMP. The sampling equipment, sample interface, analytical
systems, compound identification and confirmation procedures, calibration
standard generation apparatus, and the canister cleaning system are detailed
in this section.
3.1 SAMPLING EQUIPMENT
A perspective view of the UATMP sampler is given in Figure 3-1, and
Figure 3-2 shows the detailed layout of the sample lines, flow controller, and
the other components of the UATMP sampler. The sampler was designed to obtain
a 24-hour integrated ambient air sample in an evacuated stainless steel
canister. Separate sample lines are used for the canister sample and for the
aldehyde sample cartridges. The aldehyde sample lines are heated from the
inlet to the aldehyde cartridges.
The aldehyde sample cartridges were prepared by an EPA on-site
contractor and sent to Radian Corporation's RTP laboratory for shipment to the
UATMP sites. Each aldehyde cartridge was given a unique serial number. Three
cartridges, one blank and two duplicates, were enclosed with each canister
sent to the sites. After ambient air sample collection was complete, site
operators returned the aldehyde cartridges to the Radian laboratory in the
canister shipment container along with sample canisters and sample custody
records. The aldehyde cartridges were transferred to the U.S. EPA AREAL for
analysis. The aldehyde results will be reported in a separate report.
The UATMP samplers were set to begin drawing air at a flow rate of
150 mL/minute (min.) through the sample inlet and sample lines about six hours
before the air was directed into the evacuated sample canister(s). This
procedure ensured that once the flow in the sample line was directed into the
canister, the sample line had been well conditioned with ambient air. The
sample flow rate into the 6-L canister was controlled at approximately
3.5 mL/min. The resulting pressure in the canister after 24 hours was
approximately 1.0 to 5.0 inches (in.) mercury (Hg) vacuum. Section 4.7
presents and discusses the actual canister pressure distribution after the

canisters were received in Radian's RTP laboratory. The sample was drawn into
a canister from a sampling manifold in which the ambient air flow was several
times greater than the sampling rate. The canister was initially under vacuum
(about 29.72 in. Hg vacuum). This method of sample collection was used to
avoid potential contamination from the pump.
3.2 SAMPLER PRESEASON PREPARATION AND CERTIFICATION
The UATMP samplers were cleaned and prepared for deployment to the field
sites prior to the 1990 season. The samplers used in the 1989 program were
returned from the field sites to the Radian RTP laboratory for refurbishment.
The refurbishment involved cleaning and extensive checks of the electrical and
mechanical components of the sampler. Any worn or damaged parts were
replaced. The samplers were then reassembled and leak checked. Flow rates
for the aldehyde and canister subsystems were checked against a primary flow
standard.
All samplers were cleaned through an extended purge with humidified zero
air following the TO-14 procedure for humid zero air certification.5 Because
of the large air volume required to purge the samplers, a dedicated zero
certification manifold was utilized. After the samplers were prepared and
purged, a final analysis of the humid zero purge air was performed to serve as
part of the permanent record of any residual contaminant levels for the UATMP
target compounds. Background levels from zero air and the canister were
measured and subtracted from the certification samples collected through each
sampler unit. All analyses were performed on the GC/MD analytical system
dedicated to the UATMP program. Each sampler collected a 4-hour sample from
the zero air manifold in which the flow rate was six times the normal sampling
rate.
Acceptance criteria for the cleaned and blanked canisters used for the
sampler zero check were approximately 0.2 ppbv per target compound or the
compound reporting limit, whichever was higher. The majority of the samplers
deployed to the field met the criteria of 0.2 ppbv, or the limit, whichever
was larger, per target analyte and 25 ppbv total for all species as measured
by the flame ionization detector (FID) of the GC/MD analytical system. The
total of 25 ppbv was based on total area counts, including target compounds
arbitrarily using an average response factor of 0.001 ppbv/area count.

3.3 SAMPLE INTERFACE SYSTEM
Figure 3-3 shows the UATMP GC/MD system that includes the Sample
Interface System, the Analytical System, and the Data System. Figure 3-4
diagrams the sample valve configurations of the interface system. The upper
half of Figure 3-4 shows the configuration of the interface system valve for
the loading of sample through Trap 1 in which the organic compounds in the
sample are condensed (trapped) by flowing through a 1/8-in. stainless steel
glass-bead-filled trap that is immersed in liquid argon. The lower half of
Figure 3-4 shows the sample interface system valve in the position for
injecting the cryogenically trapped sample onto the column in the GC/MD. In
the latter mode, the argon is removed from around the trap, and the trap is
heated to about 200 degrees Celsius (°C).
The sample interface withdraws a constant sample volume of 256 mi from
the sample canister and preconcentrates the sample by cryogenic trapping (see
Load Trap 1 in Figure 3-4). Following sample preconcentration, the eight-port
sampling valve is placed in the inject position (Inject Trap 1 in Figure 3-4)
and the sample trap is rapidly heated. Helium carrier gas transports the
trapped sample directly onto the column.
Initial calibration of the GC/MD system showed that the sample interface
system provides a consistent sample volume with a precision (percent
coefficiency of variation, % CV) of less than 3.0 percent.
3.4 CALIBRATION STANDARDS GENERATION
Calibration standards were generated with a dynamic flow dilution
apparatus shown in Figure 3-5. The flow dilution system uses vendor-certified
gases ±5% to +10% accuracy and dilutes them with zero-grade air that has been
routed through a catalytic oxidizer and then humidified with HPLC-grade
water. The gases are mixed in a SUMMA®-treated mixing sphere prior to
flowing into an evacuated canister. One dilution stream of the zero-grade air
is routed through a SUMMA®-treated bubbler containing HPLC-grade water to
humidify it, and the other stream is not humidified. The dilution air streams
are then brought together for mixing with the streams from four certified
standard cylinders. Flow rates from all streams are gauged and controlled by
mass flow controllers. The split air dilution streams are metered by wet and
dry

rotameters from the humidified and unhumidified dilution air streams,
respectively. The lines and the mixing flask containing the diluted gases are
heated to 100°C to prevent condensation of liquids on the surfaces and to
reduce adsorption of organic compounds on the surfaces.
The system is evacuated with a vacuum pump while the closed canister is
connected. A precision absolute pressure gauge measures the canister pressure
before and after filling. The lines leading to the canister and to the mixing
sphere are flushed for at least 15 minutes with the diluted standard gases
before being connected to the canister for filling.
3.5 ANALYSIS
UATMP samples were analyzed for 38 target compounds by the GC/MD
system. Having simultaneous detector responses from the electron capture
detector (ECD), photoionization detector (PID), and the flame ionization
detection (FID) allowed the analyst to identify target compounds with greater
accuracy. Quantitation was done primarily using the FID response, although
the ECD was used for quantitation of most halogenated compounds. About 15% of
the 1990 UATMP samples were also analyzed for compound identification
confirmation by GC/MS, operating in the MID mode.
3.5.1 GC/MD Instrumentation
The gas chromatograph used with the multiple detector system was a
VARIAN 3700. The operating conditions for the GC/MD system are given in
Table 3-1. Figure 3-6 shows the multiple detector system arrangement.
The oven of the gas chromatograph, which contained the DB-624 capillary
column, was cooled to -30"C with liquid nitrogen at the beginning of the
sample injection. The -30°C temperature remained constant for one minute, and
then the temperature was increased at the rate of 3°C per minute, to a final
temperature of 200°C. The column effluent was routed through a 1:10 fixed
splitter that divided the flow to the ECD and the PID/FID. The smaller gas
stream from the splitter went to the ECD, and the larger fraction went first
to the PID and then the FID.

3.5.2 GC/HS Instrumentation
A total of 48 UATMP samples were analyzed by GC/MS using a FINNIGAN 4500
operating primarily in the multiple ion detection (MID) mode to enhance
instrument sensitivity. The GC/MS operating conditions are given in
Table 3-2. The full-scan mode was used occasionally to detect non-target
compounds when an interference was suspected or apparent. The MID mode was
used for all other confirmation analyses.
3.6 CANISTER CLEANUP
The sample canister cleanup system used for the 1990 UATMP is the same
as the one described in the 1990 NMOC and 1990 UATMP Quality Assurance Project
Plans (QAPPs)2'3 and the 1990 NMOC Monitoring Program.1 The canister cleanup
apparatus diagram is shown in Figure 3-7.
To clean the UATMP canisters, a bank of eight canisters is connected to
each manifold shown in Figure 3-7. The valve on each canister is opened, with
the shutoff valves and the bellows valves closed. The vacuum pump is started
and one of the bellows valves is opened, drawing a vacuum on the canisters
connected to the corresponding manifold. After reaching 0.5-mm Hg absolute
pressure as indicated on the absolute pressure gauge, the vacuum is maintained
for 30 minutes. The bellows valve is then closed. Next, air that has been
filtered, dried, and cleaned, and then humidified at about 80% humidity is
introduced to the evacuated canisters until the pressure reaches 20 pounds
(force) per square inch gauge (psig). The canisters are filled from the clean
air system at the rate of 12.0 L/min. This flow rate is the result of
6.0 L/min. passing through each catalytic oxidizer. A flow rate of 6.0 L/min.
is recommended by the manufacturer as the highest flow rate at which the
catalytic oxidizers eliminate hydrocarbons with a minimum 99.7% efficiency.
When the first manifold has completed the evacuation phase and is being
pressurized, the second manifold is then subjected to vacuum by opening its
bellows valve. After 15 min., the second manifold is isolated from the vacuum
and connected to the cleaned, dried, and then humidified air. The first
manifold of canisters is then taken through a second cycle of evacuation and
pressurization. Each manifold bank of eight canisters is subjected to these
cleanup cycles.

During the third vacuum/pressurization cycle, the canisters are
pressurized to 20 psig with air that has been filtered, dried, cleaned, and
then humidified. Each UATMP canister is blanked by the cryogenic
preconcentration and direct flame ionization detection (PDFID) method. If the
total NMOC determined by PDFID is less than 0.030 parts per million by volume
as carbon (ppmC), the eight canisters on the manifold are considered clean.
Finally, the canisters are again evacuated to 0.5-mm Hg pressure absolute,
capped under vacuum, and packed into containers to be shipped to the field
sites.
The UATMP canisters were designated from the start of the program for a
specific site. UATMP canisters from a given site are returned after analysis
and cleanup to the same site for the next sample.

4.0 RESULTS
4.1 DATA SUMMARY
This section summarizes the GC/MD analytical results. Data for each
sample, including site code, sample date, compounds identified, concentrations
for each identified compound, and the identification confidence level, are
tabulated in Appendix A. The site code descriptions, as listed in the AIRS
database, are given in Appendix B.
Table 4-1 summarizes the number of 1990 UATMP canister samples for each
site and the analyses performed. The second column of Table 4-1 is the number
of valid canister samples taken at each UATMP site. The third and fourth
columns show the number of duplicate pairs and replicate analyses pairs for
each site, respectively. At least one pair of duplicate samples was attempted
each quarter for each site. The duplicate samples were not always valid,
therefore, the number of duplicates is lower for some sites. Replicate
analyses were performed on each duplicate canister sample to measure sampling
and analysis precision. The total number of GC/MS analyses are shown in
column five of Table 4-1. Finally, the total number of GC/MS confirmation
analyses are shown in the last column of the table.
The reported concentrations for some target analytes were below the
reporting limits listed in Table 1-2. However, each identified compound was
reported and quantified, even if the concentration was below its estimated
reporting limit. All the compound identifications in the tables of Appendix A
show the level of confidence in the identification--low (L), medium (M), and
high (H). Compounds were identified in the UATMP study by retention times and
detector response ratios. If a compound in the sample was within a retention
time window (average retention time ± about 10%) for a target compound, the
response ratio for the target compound in the sample was compared to an
average response ratio for the target compound in the daily QC check standard.
The response ratios are the ratios of area count responses from two detectors,
e.g., ECD and the FID in the GC/MD analytical instrument. The precision
(percent coefficient of variation, % CV) was calculated for the compound
response ratio in the sample and the compound response ratio in the standard.

-------
If the precision was within ±20 % CV, the compound was identified with a high
level of confidence (H). If the precision was between ±20 and ±35 % CV, the
compound was identified with a medium level of confidence (M). If the
precision was between ±35 and ±40 % CV, the compound was identified with a low
level of confidence (L). Compounds with response ratios outside ±40 % CV were
usually not identified, unless there was additional evidence to indicate the
compound was actually in the sample.
Sample concentration results are grouped in two ways, by compound and by
site, and are discussed in the following subsections, 4.1.1 and 4.1.2,
respectively. For each target compound identified at all of the 12 sites,
summary concentrations are given as minima, maxima, and means. Site-specific
data summaries show which target compounds were identified in samples from
each site, and give minimum, maximum, and mean concentrations.
4.1.1 Overall Data Summary bv Compound
Table 4-2 presents the UATMP target compounds identified for all the
sites. The number of cases of identification for each compound is given,
along with the frequency at which they were identified. The frequency of
occurrence is expressed as a percent of the 349 total GC/MD analyses. Samples
collected in duplicate reflect only one sampling event, but result in two
analyses. Since duplicate samples were also analyzed in replicate, this
results in a total of four analyses from one sampling event. To avoid any
bias in the data by counting four results from one sampling event, the
duplicate and replicate results for each compound identified were averaged.
This average result was used in the statistical summaries and the frequency
calculations in Table 4-2. If a compound was identified in less than all four
analyses, the results were averaged for the analyses in which it was
identified.
Benzene and toluene were identified in each of the 349 GC/MD samples.
In addition, 1,1,1-tri-chloroethane, m/p xylene, and styrene/o-xylene,
ethyl benzene and carbon tetrachloride were reported in at least 345 out of the
349 total samples. m-Xylene and p-xylene coelute on the analytical column
used in the GC/MD system. These compounds were reported together, because it

was not possible to distinguish whether one or both compounds were present in
the sample. This was also the situation with o-xylene and styrene. n-Octane
and trans-l,3-dichloropropylene coeluted only during the first and second
quarters of 1990. On August 10, 1990, the chromatography column (DB-624) was
replaced. The new column (another DB-624) resulted in separation of n-octane
and trans-l,3-dichloropropylene. These two compounds, therefore, are listed
separately and as coeluters, since they could be distinguished from one
another for part of the year. 1,2-Dichloroethane was identified in only one
of the 1990 UATMP samples, and chloromethane was seen only twice. Reported
concentrations of the target compounds ranged from 0.01 ppbv for 12 compounds
to 515 ppbv for propylene. Average concentrations ranged from 0.07 ppbv for
dibromochloromethane to 22.83 ppbv for vinyl chloride. The concentration
range for each compound is given as minimum and maximum. The average
concentration for each compound identified is expressed in parts per billion
by volume and micrograms per standard cubic meter (^g/m3). In the latter
dimensions, the cubic-meter term is a "standard" cubic meter calculated at
25°C and 1.0 atmosphere pressure.
Table 4-3 groups the compounds by frequency of occurrence for the target
compounds in the UATMP samples. The most obvious feature of these results is
the large gap in frequency of occurrence between 95.4% for tetrachloroethylene
and 37.2% for p-dichlorobenzene. All the halogenated methane compounds
containing bromide radicals fall in the frequency-of-occurrence range of less
than 5.0 percent. This may be a reflection of the low concentrations of
bromine and bromine derivatives in ambient urban air.
4.1.2 Site-Specific Overall Data Summary
Site-specific compound identifications by GC/MD are presented in
Tables 4-4 through 4-15. The "cases" column is the number of samples in which
the compound was identified at a particular site. Concentration ranges are
given in terms of minima and maxima for each compound. The mean, or average,
concentrations are reported in the fifth through eighth columns of each
table. Means are calculated in the same way as discussed in Table 4-3.
Medians and standard deviations of the identified concentrations found in the
samples complete the data summaries for each UATMP site. Each site table
shows the total samples taken at each site throughout the year.

4.2 PRECISION
Analytical precision was estimated by comparing analytical results for
repeated, or replicate, analyses of site samples. The overall precision
results are given in Table 4-16 for all compounds and all sites. The "mean"
in Table 4-16 refers to the average concentration for each replicate pair
analysis for a given compound. The "average" in Table 4-16 is the arithmetic
mean of the concentration means of all replicate pairs, averaged over all
sites and all target compounds. The overall average concentration of the
replicate analyses ranged from 0.054 ppbv for bromodichloromethane to
107.69 ppbv for propylene, as shown in Table 4-17. The mean (and standard
deviation) for propylene is biased by one sample (two replicates) whose
concentration was about 515 ppbv. The precisions reported in Table 4-16
presents a realistic assessment of the performance of the analytical portion
of the method.
Table 4-17 shows the analytical precision of the GC/MD analysis for all
of the replicate analyses. Statistics are given for the standard deviation,
the average % CV, the pooled standard deviation, and the pooled % CV. The
precision results average 8.41% in terms of average % CV for all compounds and
all sites. In the 1990 UATMP, duplicate samples were taken and replicate
analyses were performed for each of the duplicate canisters. The only results
included in Table 4-17 are for those cases in which all four analyses were
above the reporting limit for the compound. The several statistics given in
Table 4-17 are defined below:
For a given ambient sample, let:
x.,, = the first analytical result for a given compound for
the first duplicate canister, in ppbv;
x12 = the second analytical result for a given compound from
the first duplicate canister, ppbv;
x21 = the first analytical result for a given compound from
the second duplicate canister, ppbv; and
x22 = the second analytical result for a given compound for
a second duplicate canister, ppbv.

The standard deviations for the two canisters were calculated as follows:
s = |x-2"X^!,ancl (4-3)

Replicate coefficients of variation (% CVs) were calculated as shown in

For each UATMP target compound, means, standard deviations, and % CVs were
calculated for each canister and each ambient air sample according to
Equations 4-1 through 4-6. Arithmetic averages of the canister means, the
replicate standard deviations and the replicate coefficient of variation were
calculated for each target compound and are shown in Columns 3, 4, and 5 of

-------
Table 4-17. Column 1 shows the target compound name, and Column 2 gives the
number of replicate pairs reported for each target compound. The pooled
standard deviation, sp, was calculated as follows:
SP =
(Si * sf + S32 + - Sn)
n
1/2
(4-7)
where n equals the number of replicate pairs reported for each compound. The
pooled standard deviation is given in the penultimate column of Table 4-17 for
each compound. The final column, the pooled % CV is the pooled standard
deviation (Column 6) divided by the overall mean (Column 3), expressed as a
percentage. Notice that the pooled standard deviation is higher than the
average standard deviation except in three cases (each having only two
replicate pairs) in which the standard deviations are equal. Comparing the
pooled % CV with the average % CV shows that 15 pooled % CVs are larger, 6 are
smaller, and only one is equal.
To better understand which set of statistics, the average and the pooled
values, better describes the overall precision, it is necessary to examine
some additional detail about the standard deviations. The pooled standard
deviation (Equation 4-7) is the appropriate overall statistic if all of the
standard deviations, from which it is calculated, are equal.
Figures 4-1 through 4-8, plot the replicate standard deviations as
functions of concentration for 1,1,1-trichloroethane, carbon tetrachloride,
benzene, toluene, tetrachloroethylene, ethylbenzene, m/p-xylene and
styrene/o-xylene, respectively. Figure 4-1 through 4-8 also show the
regression line determined by the method of least squares. Although the liner
relationship is not exact, it does show that the standard deviations are not
equal and not independent of concentration. The presence of a number of
larger standard deviations in the case of every compound heavily influences
the "pooled" standard deviation calculation, biasing the overall measure of
precision to a larger-than-appropriate measure.
Because the standard deviations appear to be functions of concentration,
the average standard deviations given in Table 4-17 are appropriate "overall"
measures of precision. These results indicate a high degree of precision,

considering there were 38 compounds and 12 sites. The % CV and absolute
percent difference results should be viewed as a measure of analytical
precision, not the total method precision. Table 4-17 details the replicate
statistics by target compound. The overall average % CV of 8.41 indicated
good overall agreement of the repeated analyses, hence precision. For the
1989 UATMP, the overall precision in terms of percent coefficient of variation
was 8.04%, which indicates that the sampling and measurement systems were
quite consistent between the years. Table 4-18 gives the replicate statistics
for all compounds by quarters of 1990, and cumulatively for the entire year.
The results from this table show consistency throughout the year.
Sampling and analysis precision is summarized in Table 4-19 and was
calculated from analyses of duplicate samples. The data in the table include
the analytical results from all the sites and all the target compounds. The
average % CV and absolute percent difference are 12.3 and 12.7, respectively.
These values are slightly larger than the corresponding results for replicate
analyses because the duplicate values include the sum of the sampling and
analytical error. The % CV and absolute percent difference for the duplicate
sample analyses results reflect careful sampling and analysis procedures and
maintenance of quality control. Table 4-20 details the duplicate statistics
by compound. The largest average % CV was for trichloroethylene and equaled
28.0. The overall weighted average % CV for all compounds is 11.67.
Table 4-21 presents the duplicate sample statistics by quarters for 1990 and
cumulatively for the entire year. Overall mean concentrations appear to
decrease from the first quarter of the 1990 program through the fourth quarter
of the 1990 program, but the % CV does not track the same trend. The
unusually high value of the propylene concentration measured in the first time
period, 515.49 ppbv, of course biases the mean and standard deviation for that
time period. In the second time period the percent coefficient of variation
appears to be higher than expected, however, the number of duplicates for that
time period was low, which frequently accounts for extreme values of
precision. The overall annual mean % CV of 12.27 is a reasonable value for
precision. Precision for the 1989 UATMP averaged 11.36, which shows
consistency between the two years.

4.3 SAMPLING AND ANALYTICAL PRECISION
In Section 4.2, precision was described in terms of repeated analyses of
duplicate samples. On the day that duplicate samples were taken, two
canisters were connected to a single intake manifold by means of a tee
connection. Each duplicate canister was analyzed twice on successive days.
Analytical precision for each target compound was determined from the repeated
analyses of a single canister. Sampling and analysis (duplicate) precision
was determined from the standard deviation of all four analytical
measurements.
Coefficients of variation for the replicate analysis were determined
from the standard deviations and means of each replicate analysis. For
duplicate analyses, duplicate precisions and the means for each duplicate were
used to estimate the coefficients of variation for each duplicate sample pair.
Duplicate statistics by compound are given in Table 4-20. Using the
same notation given earlier for the replicate analyses of duplicate samples,
the ambient sample mean concentration was calculated as follows:
x = - ,01
_
x -
The overall means average the means for each duplicate sample and are shown in
Column 3 of Table 4-21. Duplicate standard deviations were calculated as
follows:
(X11-X)2+(X1,-X)2+(X,1-X)2+(X,,-X)2) ]1/2 (4_1Q)
Duplicate % CVs were calculated by:
%cvdl = -fSi*ioo. (4-11)
J\.
252-045-06/cah.207f
=-nal Reoort - 1990 4-37
-------
Average standard deviations for each compound were calculated by taking the
standard deviations from calculated using Equation 4-10 and averaging over all
the duplicate samples.
Average % CVs (Column 5) for each compound were estimated by taking the
arithmetic averages of the % CVs for each duplicate canister. Pooled standard
deviations (Column 6, Table 4-21) were calculated by an equation similar to
Equation 4-7 using the standard deviations for each duplicate. The pooled %
CV (Column 7) was calculated by dividing the pooled standard deviation by the
overall mean (Column 3).
The remarks offered earlier regarding the replicate standard deviations
being functions of concentration apply to the duplicate standard deviations.
As seen in Table 4-21, the duplicate pooled standard deviations (and % CVs)
are larger than the average standard deviations, and are functions of
concentration. It is appropriate, therefore, to use an average standard
deviation to describe the overall precision of the duplicate measurement. The
duplicate precision is assumed to be the combined sampling and analytical
precision. In a subsequent section, the sampling and analytical precisions
are separated and then recombined to give an overall precision of the sampling
and analysis process.
Table 4-21 shows the summary duplicate statistics by quarters and for
the entire year. The second quarter appears to have an excessively high
percent coefficient of variation, but it represents only two duplicates,
whereas a typical 3-month period would have about 12 duplicates.
In this section, the sampling and analysis variability is separated by
means of an analysis of variance. The replicate-duplicate data described
above was assembled for those target compounds in which the concentration
measurement was greater than the detection limit in each of the four analyses
for each ambient sample taken. The ANOVA model chosen for each target
compound, was:
Yijic = u.+Si+Dj(i)-eic(ij), (4-12)
262-045-06/cah.207f
Final Reoort - 1990 4-38
-------
where:
Yijk = measured concentration for sample i, duplicate
canister j, and replicate k;
// = overall mean concentration;
Sj = ambient air sample i;
Dj(j) = pooled duplicate j, nested in sample i; and
ek(jj) = residual error, assumed to contain the
analytical error.
In these effects, the duplicate effects are nested within the sample effects
and the duplicate effects are pooled within each sample and between samples.
Table 4-22 summarized the results of the ANOVA for 22 target compounds. The
table shows the compound, the number of samples, the variances (or the mean
squares), percent sampling and analysis contributions, sampling and analysis
standard deviations, a total sampling and analysis standard deviation, the
overall mean concentration, and finally an overall percent coefficient of
variation, or precision for each compound. The results are shown in
Table 4-22 will be illustrated for acetylene.
The number of samples for which there was measured concentration for
acetylene was 1, resulting in two duplicate canister and two replicate
analyses from each canister for a total of four analyses. As expected, the
mean square for samples (S;) was highly significant. The pooled mean square
for duplicates from the nested ANOVA includes both sampling and analytical
error and equals 1.464100.
1.464100 = al + 2al, (4-13)
where:
1.464100 = pooled mean square for duplicates;
cra = residual error mean square, analytical variance

From Table 4-22, the analytical variance:
ai = 0.29600, (4-14)
02 = (1.464100-0.29600) (4-15)
2 = 0.584050. (4-16)
Therefore, the percent of the variability due to sampling:
(0.584050)
(0.296000+0.584050)
The percent of the total variability due to analysis is the complement, equal
to 33.63 (Column 6, Table 4-22). Expressing the precision in terms of
standard deviations gives:
For sampling ss = yo.584050 = 0.76423, and (4-18)
For analysis sa = ^0.296000 = 0.54406. (4-19)
A total precision (standard deviation) for sampling and analysis, i.e., one
sample and one analysis, may be estimated as:
st = JO. 584050+0. 296000, and (4-20)
Sc = 0.93811. (4-21)
The overall mean concentration for acetylene in the (one) sample was
4.945 ppbv. The overall percent coefficient of variation for sampling and
analysis (one sample and one analysis) is:
%CV = ^*100 = °-93811*ioo (4-22)
x 4.945
%CV = 18.97 . (4-23)
:62-045-06/cah.207f
=mal Report - 1990 4-41
-------
Note that for 12 of the compounds the sampling and analytical (or duplicate)
error was not significantly different from the analytical error. For those
cases the sampling variance component is shown as 0.0000 and the % variability
due to sampling is 0.00.
For those compounds in which the ANOVAs showed it was possible to
separate the sampling and the analytical error, there does not appear to be
any pattern to explain why the results are the way they are. For example, one
would normally expect benzene and toluene to behave similarly. The data below
summarized the results for benzene and toluene:
% Variability due to
Compound Sampling Analysis
Benzene 17.55 82.45
Toluene 91.86 8.14
At this time the reason for this behavior is not explained. In the case of
propylene, the analysis was performed on only four of the five ambient
(duplicate) samples. The reason the fifth sample was not included was the
concentration of the fifth sample averaged 515.49 ppbv, approximately 100
times larger than the average of the other four samples. The extremely large
value for the fifth sample would have biased the mean and standard deviations
and was; therefore, not included in the analysis.
4.4 ACCURACY
Accuracy for the GC/MD analysis was measured in terms of external audits
received from QAD, of the EPA. Four analytical audits were conducted in 1990.
Both the GC/MD and GC/MS analytical systems were subject to the audits,
although GC/MS was used primarily for the purpose of compound identification
confirmation, not quantitation.
Table 4-23 gives the results of four EPA audits performed on the GC/MD
system. Seven results out of 64 cases showed percent biases greater (or less
than) than ± 30% bias contained in the data quality objectives for the 1990

UATMP. The overall average bias was 7.95 percent. Chloroform was the only
compound which showed a bias greater than 30% for more than one audit.
Table 4-24 gives the results for four EPA audits performed on the GC/MS
system. Five out of 68 cases showed percent biases outside the ± 30% range
contained in the data quality objectives. Styrene was the only compound which
showed a bias less than 30% for more than two audits. In EPA Audit No. 1336,
styrene showed a bias of -86.49%, which was the smallest bias reported for any
compound.
Appendix D presents a fuller discussion of the four audits conducted by
EPA's Research and Monitoring Evaluation Branch (RMEB) of the Quality
Assurance Division (QAD) of AREAL. The discussion is in the form of memoranda
from Radian Corporation to RMEB addressing the results for each audit. For
the most part the discussion centers on probable causes for the biases which
are greater than +30% or less than -30%.
4.5 GC/MS COMPOUND IDENTIFICATION CONFIRMATION RESULTS
Compounds were identified by the GC/MD analytical system using a
combination of retention time, PID/FID response ratio, ECD/FID response ratio,
and detector specificity. Compound identification confirmation was
accomplished by analyzing about 15% of the samples by GC/MS in the MID
mode. Table 4-25 summarizes the results of the 1990 UATMP compound
identification confirmation. The GC/MS analyses confirmed 89.40% of all the
compound identifications resulting from the GC/MD analyses.
In determining the confirmation rate, there were four possible cases:
(1) positive GC/MD identification - positive GC/MS identification,
(2) positive GC/MD identification - negative GC/MS identification,
(3) negative GC/MD identification - positive GC/MS identification, and
(4) negative GC/MD identification - negative GC/MS identification.
A compound identification was confirmed if both GC/MD and GC/MS identified the
compound, or both did not identify the compound. If the compound identified
on one analytical system was below the estimated reporting limit of the other
system, this was also considered a confirmation.

4.6 SAMPLE COMPLETENESS
Percent completeness, defined as the number of scheduled samples that
resulted in a valid sample, gauges several quality assurance measures. Site
operator performance, training procedures and instructions for site operators,
communication between the site operators and the Radian site coordinator, and
equipment reliability all affect the number of valid samples obtained.
Table 4-26 summarizes the completeness results at each site in the 1990 UATMP.
Completeness ranged from 82.4% at W2DC, to 100% at several sites. The overall
average percent completeness was 94.5.
Table 4-27 lists the invalidated samples by site code and ID number,
along with the reason the sample was invalid. Examination of the reasons for
the invalidated samples indicates that site operator error was usually
involved. In several cases, samples were invalidated because the canister
vacuum was too high upon receipt. High canister vacuum was usually the result
of improper setting of the flow rate by the site operator or failure of the
site operator to open the canister valve to collect the sample. In three
cases, the sampler was not operating properly at the scheduled time of
collection. Additional samplers were provided as needed to enable the sites
to continue sampling.
4.7 CALIBRATION RESULTS
Summary results for daily calibration of the three detectors in the
GC/MD system are given in Tables 4-28, 4-29, and 4-30. The daily calibration
factors for the FID, PID, and ECD are given in the three tables in units of
ppbv per area count (a.c.). Minima, maxima, means, standard deviations, and
% CV are given by compound. Overall average % CV are shown for each detector
also. Daily calibration factors are used to ensure that the analytical
calibration remains stable throughout the year. Calibration checks at 5 ppbv
were analyzed daily for each target compound. The calibration checks produced
response factors for each compound and cumulative means, standard deviations,
and % CV's. Any compound whose cumulative mean, standard deviation, and/or
% CV changed more than about 2.0% in a single day could be identified by
comparison to the previous cumulative values. Such an occurrence would signal
an error in the calibration or malfunction of a detector or other part of the
GC/MD system. No such occurrence was noted in the 1990 UATMP.

The average % CV for all compounds for the FID was 20.36. The average
% CV for the PID and the ECD were 31.10 and 29.74, respectively. Compounds
quantitated on the ECD were 1,1,1-trichloroethane, bromochloromethane, carbon
tetrachloride, chloroform, tetrachloroethylene, and trichloroethylene. All
other compounds were quantitated on the FID.
4.8 CANISTER PRESSURE
Monitoring canister pressures is an important aspect of quality
assurance in any program involving ambient air sampling. The driving force
for collecting a sample is the initial vacuum in the canister. The canister
is cleaned and evacuated before being shipped under vacuum to a site. Once
the canister is connected to the sampling system, the canister valve is
opened. The UATMP sampler controls when the sample is allowed to enter the
canister, the length of time the sample is taken, and the flow rate of air
into the canister. The final sampling pressure is important. Ideally, the
flow rate is maintained at a constant value throughout the sampling interval
of 24 hours so that an integrated sample is taken. An integrated sample
represents the integrated average concentration for the sampling period. To
permit the flow controller in the sampler to maintain a constant flow rate
throughout the sampling period, a pressure drop of at least 0,5 in. Hg must be
maintained. Therefore, the final pressure in the canister must be negative,
relative to atmospheric pressure, i.e., it must still be under a slight
vacuum.
On the other hand, if the final vacuum in the canister is too high, it
is difficult to take a sufficient amount of the sample from the canister for
analysis. The UATMP sampler was designed to have about 3 to 6 in. Hg vacuum
after the 24-hour sampling period. About 60% of the invalidated samples in
the 1990 UATMP resulted from vacuum that were too high. The voided samples
are listed in Table 4-27, along with the reasons they were invalidated.
Table 4-31 summarizes the canister pressures measured after receipt in
the RTP laboratory. The overall average pressure measured for all the
canisters from all the sites was 5.26 in. Hg vacuum. The pressure ranges and
distribution are shown in Table 4-31. The third column of the table gives the
cumulative number of cases and the fourth column normalizes the number of

cases into cumulative percentages. For example, the results show that 8.83%
of the canisters had pressures less than 10-in. Hg vacuum at the time of
analysis. Upon receipt in the laboratory after sampling, the canisters
typically had at least 18 hours of equilibration time to completely come to
laboratory temperature before measuring the gauge pressure (inches Hg vacuum)
prior to analysis.
No site had more than three samples invalidated because of vacuum that
was too high upon receipt at the laboratory. The analyst notified the Radian
site coordinator when a canister was received with an initial vacuum greater
than 10 in. Hg so that appropriate corrective action could be taken.

5.0 DISCUSSION
Three aspects of data characterization are discussed in this section:
data frequency, concentration correlations, and concentration ratios for the
most frequently identified compounds.
Data frequency distributions are given for the concentrations of the
eleven most commonly identified compounds in the 1990 UATMP. These compounds
were 1,3-butadiene, 1,1,1-trichloroethane, carbon tetrachloride, benzene,
trichloroethylene, toluene, tetrachloroethylene, ethylbenzene, m,p-xylene,
styrene/o-xylene, and p-dichlorobenzene. In all cases the frequency
distributions approximate the lognormal distribution.
The second aspect of the results of the 1990 UATMP is the correlation
between the concentrations of seven frequently identified compounds:
1,1,1-trichloroethane, carbon tetrachloride, toluene, styrene/o-xylene,
m/p-xylene, ethylbenzene, and benzene. The same compound list was used in the
1989 UATMP Final Report. Several of the 1990 UATMP sites, BRLA, C4IL, CANJ,
H1TX, SAIL, W1DC, W2DC, and W1KS, were also included in the 1989 UATMP, which
permit comparing correlations among the compounds between years. Strong
correlations were almost universally observed between: (1) m,p-xylene and
styrene/o-xylene, (2) ethylbenzene and styrene/o-xylene, and (3) ethylbenzene
and m,p-xylene. Correlations involving the above components with benzene or
toluene were not consistent and were site specific. Site locations in
airsheds having several petrochemical facilities, such as H1TX, BRLA, and
SAIL, showed little correlation of benzene concentrations with any of the
other six compounds listed. This may be due to independent benzene emission
sources in the area not involving steady-state and/or photochemical sources of
benzene and toluene. There were few correlations between carbon tetrachloride
and 1,1,1-trichloroethane, and carbon tetrachloride appeared to be independent
of all the other compounds mentioned above.
Thirdly, the ratios of benzene, toluene, m,p-xylene, and
styrene/o-xylene to ethylbenzene were calculated. This provides a reference
for comparison to other databases that also include this ratio.

-------
to the stem-and-leaf plot, each of the other statistics are tabulated in each
compound, including: the number of cases of identifications, minimum,
maximum, mean, standard deviation, lower hinge (25th percentile), median (50th
percentile), and upper hinge (75th percentile).
The stem-and-leaf plots show the actual concentrations truncated to two
or three decimal points. The digits to the left of the vertical column of
open space are called stems and the digits to the right of the column of open
space are called leaves. The data are sorted from the smallest at the top of
the graph, to the largest at the bottom of the graph. Figure 5-1, for
example, shows the stem-and-leaf plot for 1,3-butadiene, pooled over all
sites. The minimum is shown to be 0.030, which accounts for the first zero on
the right of the "H" on the top stem-and-leaf (row). The maximum of
142.6 ppbv is shown on the bottom stem-and-leaf as "142 6". The plot shows
106 cases (or leaves) one for each concentration of 1,3-butadiene reported for
the 1990 UATMP. The "H's" in the open vertical space locate the stem-and-leaf
for the lower and upper hinges or quartiles, and the "M" locates the stem-and-
leaf for the median. The median separates the sorted concentrations into two
equal halves; the hinges (or quartiles) separate each half into quarters. The
range between the two hinges is called the interquartile range.
The stem-and-leaf plots shown for the most frequently occurring target
compounds of the 1990 UATMP show skewed distributions and suggest lognormal
distributions. In most cases, however, the tails in the fourth quartiles
extend longer than would be expected if the data followed the lognormal
distribution exactly. A consequence of these observations is that the
arithmetic means and standard deviations are biased high. 1,3-Butadiene is a
good example of this fact with the unusually high concentration of 142.6 ppbv,
whereas, the next highest concentration is 34.6 ppbv. For such cases, the
median (0.310 ppbv), and the interquartile, range (0.960-0.130) are better
measures of central tendency than the arithmetic mean 3.24 ppbv. Fifty
percent of the measured concentration values lie in the interquartile range.
For the case of the 1990 UATMP 1,3-butadiene data, the arithmetic mean does
not fall in the interquartile range.
If the lognormal distribution is the appropriate one to describe
equilibrium or steady-state concentrations, the long tails in the fourth

quartiles suggest a number of "outliers," that is, concentrations that do not
fit the expected distribution. Such occurrences probably result from
site-specific nonrandom emissions from special sources.
5.2 CORRELATION OF COMPOUND CONCENTRATIONS
The correlations between compound concentrations are presented in
Pearson correlation matrices for each site in Figures 5-12 through 5-23.
Correlations were calculated for 1,1,1-trichloroethane, carbon tetrachloride,
toluene, styrene/o-xylene, m,p-xylene, ethylbenzene, and benzene.
The concentration data were grouped for each site. For BRLA, as seen in
Figure 5-12, there were 29 days in which the concentrations of the seven
compounds were recorded. The Pearson correlation matrix tabulates the
correlation coefficient for each possible pair of compounds. At BRLA, very
little correlation is shown between any pair of compounds tested. In the 1989
UATMP, the only pair of compounds that showed a significant correlation was
m/p-xylene and styrene/o-xylene with a correlation coefficient of 0.928. For
the 1990 UATMP, the correlation between these compound was only 0.371, as
shown in Figure 5-12.
The 1990 UATMP site at CANJ (Figure 5-13), on the other hand, shows
strong correlations (coefficients of correlation >0.9) for toluene,
styrene/o-xylene, m/p-xylene, and ethylbenzene. Benzene, on the other hand,
shows little correlation with any other compound, although it showed strong
correlations with the other olefins in 1989. For CANJ (Figure 5-13)
significant correlations are seen between toluene and 1,1,1-trichloroethane,
and between ethylbenzene and 1,1,1-trichloroethane..
For C4IL (Figure 5-14), strong correlations are seen among
styrene/o-xylene, m/p-xylene, and ethylbenzene only. For W1KS (Figure 5-23),
W1DC (Figure 5-21), and W2DC (Figure 5-22) the correlations for all compound
pairs were similar between the 1989 UATMP and the 1990 UATMP. For all the
other sites no clear pattern emerges between sites and years. The chlorinated
compounds, 1,1,1-trichloroethane and carbon tetrachloride, however, showed
little correlation with any of the other compounds tested.
The graphs in Appendix C depict correlation, and lack of correlation,
between 1,1,1-trichloroethane and carbon tetrachloride concentrations for all

sites (Figures C-l through C-14). Figures C-15 through C-28 show the
correlation of concentrations for benzene, toluene, ethylbenzene, m,p-xylene,
and styrene/o-xylene for all sites.
5.3 RATIOS OF COMPOUND CONCENTRATIONS
The ratios for benzene, toluene, and the total xylenes to ethylbenzene
are shown by site and overall in Table 5-1. The ratios of concentrations
among benzene, toluene, and the total xylenes were chosen with respect to
ethylbenzene because these compounds are almost universally found in urban
ambient air samples, and because the concentration of ethylbenzene is
generally lower than the other compounds. Moreover, other studies have
examined the same ratios found in other data sets, e.g., the TAMS and the
National Ambient Volatile Organic Compound Data Base.5
Each compound ratio in Table 5-1 was calculated for each identification
case in each sample, then the average of these ratios was determined. Ratios
are given for the 1989 UATMP and 1990 UATMP. Overall average
benzene:ethyl benzene ratios are generally less than ratios of
toluene:ethyl benzene or xylenes:ethyl benzene. Benzene:ethyl benzene ratios
range from 2.74 for MIFL to 10.12 for SAIL with an overall average of 4.52 for
the 1989 UATMP and 5.48 for the 1990 UATMP. Toluene:ethyl benzene ratios are
generally higher than benzene:ethyl benzene ratios and range from 5.82 to
29.04. Xylenes:ethyl benzene ratios averaged 7.57 in 1989 and 8.80 in 1990 and
ranged from 6.05 to 20.82.

6.0 RECOMMENDATION
Based in the 1990 UATMP, the following recommendations are made
regarding canister cleanup studies, instrument detection limit studies,
measurement of additional compound concentrations, reporting of precision, and
external audits.
6.1 CANISTER CLEANUP STUDY
A number of preliminary studies have been performed to determine
carryover from one UATMP canister sample to the next. It is recommended that
the available data be processed and interpreted. It is felt that by such an
analysis, either additional data needs may be indicated, or no further study
will be needed. One of the things the cleanup data interpretation is expected
to do is to determine if molecular size and molecular weight is a determinant
factor in carryover of the compound from sample to sample after cleaning.
6.2 INSTRUMENT DETECTION LIMIT STUDY
A study is needed to determine the instrument detection limits (IDLs)
for all target compounds using the GC/MD system. Although the IDLs would not
be used to exclude data, it would be beneficial to the UATMP, and to the
models for which the data are used, to realize the analytical risks involved
in compound identification and quantitation.
6.3 ADDITIONAL TARGET COMPOUNDS
The target compounds listed in the USEPA Compendium Method TO-144
include several compounds not currently targeted for the UATMP. It is
recommended that additional compounds be included in the UATMP target compound
list.
6.4 PRECISION MEASURES
In the 1989 -UATMP final report, precision was estimated using an average
percent coefficient of variation for each target compound, in which %CV was
calculated from repeated analyses from the same canister. In the 1990 UATMP
final report, precision was estimated using the average %CV for each compound,
and also using a pooled standard deviation (and pooled %CV). In addition, in
the 1990 UATMP final report (this volume) an investigation was initiated into
the relationship between standard deviation of replicate analyses and average
concentration of the sample. It is recommended that these procedures become
routine analyses of future UATMP data.
-------
6.5 EXTERNAL AUDITS
It is recommended that a procedure be developed for supplying six
external audits in the 1991 UATMP. It may be possible for the Quality
Assurance Division to continue to provide audits for the UATMP target
compounds, or to develop another contractor to provide such audits, or there
may be a procedure which uses National Institute of Science and Technology
(NIST), or Scott Standards for external audits.
It is also recommended that continued effort be expended to continue
development and testing of field audit procedures.

MEMORANDUM
TO: Howard Crist
RMEB/QAD/AREAL (MD-77B)
FROM: Wendy Moore
Radian Corporation
DATE: June 19, 1990
SUBJECT: High bias results for tne first UATMP auait of 1990. ID ^
The results of the first UATMP audit of 1990. # 1164, reflect high bias percentages for
three compounds: chloroform, chlorobenzene, and o-xyiene.
The daily QC standard response factors for chloroform were in control for the last three
months. Previous audits for chloroform have been within acceptable bias ranges. It is
possible that a coeiuting compound was present in the standard that increased the reported
concentration. The canister used for the audit was blanked by GC/MD before filling and
no target compounds above 0.2 ppbv were identified. The audit sample will be analyzed
by GC/MS in full scan mode to identify any non-target coeiuting compounds that may have
interfered with chloroform.
The high bias result for chlorobenzene appears to be due to an inaccuracy in the new
cniorooenzene standard concentration. The chlorobenzene standard used for calibration
was replaced March 26. 1990. This audit was the first check for accuracy performed on this
standard. To confirm the possibility of an inaccurate standard concentration, a
chlorobenzene standard prepared from another Scott certified cylinder in Austin was
analyzed. The cnlorobenzene concentration in the audit sample was quanntated at ".9 using
the response factor from the Austin standard: This quantitation results in a bias of 3.9
percent. The new chlorobenzene standard currently in use will be corrected for the
difference in concentration and all samples analyzed during the period in which the
inaccurate concentration was used will be corrected for chlorobenzene. This will include
only the first quarter samples for UATMP 1990. which have not yet been reported.
-------
-------
The concentration for o-xyiene was reported along with the styrene concentration since
these two compounds coelute on the GC/MD system. This coelution was footnoted in the
audit results Radian submitted. The % bias calculated by EPA did not reflect the styrene
concentration. When the spiked styrene value is added to the o-xyiene value, the
concentration for both compounds is 12.5 ppbv. The reported concentration for both
compounds together was 14 ppbv, resulting in a % bias of 12, which is well within the
acceptable range.
Any conclusions made from the full scan GC/MS analysis of this audit for chloroform will
be reported. Please call Joann Rice or me if you have any questions.

MEMORANDUM
TO: Frank McElroy
RMEB/QAD/AREAL (MD-77)
FROM: Joann
DATE: February 21. 1991
SUBJECT: Performance Audit Results for the Second and Third UATMP
Audits of 1990 (1252 and #1366)
Analytical results for both performance audits %vere submitted to the EPA on
Decemoer 3. 1990. Tne nominal concentrations from the auditor were received
January I7. 1991. ana the percent bias was calculated for ootn the GC/MD and GC/MS
analytical systems. The results are given m Table 1.
AUDIT #1252
The GC/MD results for tetrachioroethylene and styrene/o-xyiene were outside the 30
percent window. The percent bias was 57.69 and 41.18 percent respectively. As
indicated in Radian's December 3rd memo from Emily Bowies, this audit was
contaminated by an unknown source (see Figure 1). The target compounds in question
are indicated on the chromatogram.
The audit canister cleanliness was assessed by GC/MD analysis prior to submitting the
canister 10 EPA for preparation. Tne analytical system was also assessed for cleanliness
\v analyzing a wet zero samoie prior to audit analysis. Both the canister and analytical
->stern cnecxs were acceptaoie.
It is likely that the contamination affected the ability for accurate quantitation by
GC/MD and biased the results in a positive manner. The bias is not a result of the
calibration standards used. The GC/MS is calibrated with the same certified standard
stock gas and analytical results for these compounds are acceptable. The anility for the
GC/MS to deconvoiute peaks negates any quantitative interference due to
contamination.
The GC/MS results for chlorobenzene and ethylbenzene were outside the 30 percent
bias criteria (-35.92 and -31.43. respectively). This negative bias may be due to the
lengtn of time that transpired between audit canister preparation ana GC/MS analysis.
The audit canister was received at PPK in June and was not analyzed by GC/MS until
November llth. due to instrument down time. The results may indicate instability of
these compounds in the canister over the 5 montn period.
Since tne GC/MS is used for qualitative confirmation of GC/MS identification, no
corrective actions are recommended.
-------
AUDIT #1366
The results of chloroform, 1.2-dichioropropane. and trichloroethyiene were ourside the
50 percent criteria (54.29, 46.58. and 61.11, respectively). Prior to the analysis of this
performance audit on September 20th. a new vendor certified cylinder was put into use
September 18th. When the response factors from several daily QC check standards
made from the new cylinder are compared to the previous QC check standard response
factor database, large positive biases result for these compounds. The percent biases are
22.72. 34.70, and 44.52 for chloroform. 1,2-dichloropropane. and trichioroethyiene. Tne
difference between the old and new certified standards explains the bias results for
1.2-dichioropropane and trichloroethyiene. When these audit biases are corrected, the
results are 11.88 and 16.59 for 1,2-dichioropropane and trichloroethylene.
The bias correction for chloroform does not bring the result within the required criteria
at 31.57 percent. The reason for the high chloroform bias is unknown at this time and
results for subsequent audits will be monitored in an attempt to resolve the discrepancy.
Quantitative GC/MD results for 1.2-dichioropropane and tnchloroetnane in the third
quarter of 1990 are affected. The GC/MD results for this quarter, and ail relevant
statistics, will be corrected in the final UATMP report to be prepared at the end of the
monitoring program. The certified calibration stock standard concentration has also
been adjusted to reflect the biases for these compounds.
The percentage bias for trichloroethylene as analyzed by GC/MS was 66.67. which
compares to the GC/MD result, and is due to the calibration standard bias. When this
compound is corrected in accordance with the calibration standard discrepancy, the
resulting bias is 22.15 percent. The bias for styrene was -86.49 percent. The 0.5 ppbv
styrene result has been checked and verified as reported. The extremely low recovery
for styrene is possibly due to the length of time between the audit preparation and
analysis because of instrument down time. The canister was received at PPK Septemoer
18th and analyzed by GC/MS on November llth.
'Since the GC/MS is used for qualitative confirmation of GC/MD identifications, no
corrective actions are recommended.

MEMORANDUM

Office of Air Quality Planning and Standards i'MD-14)
FROM: Joann Rice
DATE: June 26. 1991
SUBJECT: Performance Results for the Fourth UATMP Audit (#1496) of 1990
The results for the fourth UATMP audit of 1990. ID #1496. reflected high GC/MD bias
percentages for bromomethane and chloroform (-41.67 and 33.33 respectively).
The high percent bias for bromomethane was caused by a transcription error during the
data reduction process, which affected the reported GC/MD value. The corrected
concentration is 2.3 ppbv and the recalculated bias of -2.91 percent is within the
acceptable range of ±30 percent.
The results for chloroform have oeen consistently high, just outside the -JO percent
window, for 3 of the 4 audits of 1990. Tne reason for the bias is unknown at this time.
Chloroform was not present in the analytical system and audit canister blank analyses.
The GC/MS analytical system is calibrated with working standards prepared from the
same stock cylinders as used for the GC/MD system, and these results for chloroform
are acceptable (20.83 %). This indicates that the stock standard concentrations and
calibration standard preparation procedures are satisfactory.
Preventative maintenance is being performed on the analytical system prior to analysis of
the 1991 UATMP samples. A new analytical column has been installed and improved
calibration procedures are being implemented. Subsequent analysis of audit samples will
be monitored to resolve the chloroform discrepancy. The next EPA analytical audit will
be analyzed by GC/MS in the full scan mode to determine the presence of compounds
that mav co-elute with chloroform.

Pa.ee 2
The GC/MS result for bromoform was also outside the r30 percent bias acceptance
criteria (-54.17). All calculations were checked and no transcription or calculation errors
were found. Since the GC/MS system is used for qualitative confirmation of GC/MD
identifications, and no qualitative issues were identified, no corrective action is
recommended at this time.
If you have any questions or need any clarifications, piease call.

16. ABSTRACT
From March 1990 through February 1991 samples of ambient air
were collected at 12 sites in the eastern part of the U.S. Every
12 days, air was integrated over 24-hour periods into passivated
stainless steel canisters. Simultaneously, air was drawn through
cartridges containing dinitrophenylhydrazine to collect carbonyl
compounds. The samples were analyzed at a central laboratory for
a total of 37 halogenated and aromatic hydrocarbons,
formaldehyde, acetaldehyde, and other oxygenated species. The
hydrocarbon species were analyzed by gas chromatography/multiple
detectors and gas chromatography/mass spectrometry, while the
carbonyl species were analyzed by liquid chromatography. An
extensive quality assurance program was carried on to secure high
quality data. Complete data for all the hydrocarbon samples are
presented in this report.
