PREFACE
This document, 1987 NONMETHANE ORGANIC COMPOUND MONITORING PROGRAM
FINAL REPORT VOLUME 2 TOXIC SPECIES, summarizes the data obtained from
a program designed to obtain an estimate of the concentration of selected
toxic compounds in the ambient air, i.e., screening. The samples were
collected primarily for measurement of their nonmethane organic compound
(NMOC) concentrations, data which were needed for ozone modeling. Since
there was extra gas remaining after the measurements for NMOC had been
made, other analyses of the samples were possible. The compounds selected
for measurement were those which were thought to be of most concern to
risk assessment personnel.
A new measurement method was developed by the Environmental Monitoring
and Systems Laboratory (EMSL) and Radian Corporation for these samples:
gas chromatography, multidetector (GCMD). In this method, after passing
through a chromatographic column, the gas stream is split into two parts.
One part passes through two detectors in series, first a photoionization
detector (PID) followed by a flame ionization detector (FID). The other
part passes through an electron capture detector (ECD). Since most com-
pounds are not sensed equally efficiently by these three detectors,
inspection of the simultaneous traces from the detectors frequently per-
mits identification and quantitation of the individual species. The
experimental apparatus is described in this document.
The original samples were collected during the 6 to 9 AM time
period on week days only during the months June through September. The
data cannot be used to calculate 24-hour average concentrations of the
species, nor can they be used to infer annual average concentrations.
These data should be used only to get an estimate of the kinds and con-
centrations of putative toxic species in the ambient air of the cities
where samples were collected (for other purposes).
During all large measurement programs, many people contribute to
their success. It is impossible to acknowledge everyone. However, the
following Radian Corporation personnel were especially important to the
success of this program: Dave-Paul Dayton, Robert J. Jongleux, Robert A.
McAllister, Wendy Moore, Joann Rice, and Denny Wagoner. Their dedication
to seeing the project through is greatly appreciated.

8.0 THREE-HOUR AIR TOXICS SUMMARY
The 1987 Nonmethane Organic Compound and Air Toxics Monitoring Program
included three-hour ambient air samples at 32 urban sites in the contiguous
United States. Volume I presents a description of the equipment and data
obtained for the nonmethane organic compound (NMOC) analyses of ambient air
samples obtained during 1987. This report, which is Volume II, presents the
analytical equipment description, the analytical results, and discussion for
those three-hour ambient air samples analyzed for specific air toxic
compounds. Samples at 15 of the NMOC sites were analyzed for 37 air toxic
compounds, primarily benzene, toluene, xylenes, and halocarbons.
A multidetector gas chromatographic (GC/MD) analytical system, which
included a sample interface, was developed and tested for measuring the
concentration of 37 toxic compounds in ambient air samples. The sample
interface system can deliver equal volumes of ambient air sample from
p
6-liter Summa -treated canisters under pressure or under vacuum to any
analytical device without drying the sample. The sample interface can
inject the sample into an analytical device, preconcentrate the sample
cryogenically, or inject the sample into an adsorbent bed.
p
A VARIAN 3700 gas chromatograph was configured with a 30 m x 0.53 mm,
DB-624 Megabore fused silica capillary column, followed by a precision
splitter which routed one-tenth of the gas through an electron capture
detector (ECD), and the remainder through a photoionization detector (PID)
in series with a flame ionization detector (FID). Three-hour pressurized
ambient air samples obtained during the Summer of 1987 from 15 urban sites,
were analyzed on the GC/MD system. One sample from each site was analyzed
twice to determine the analytical precision; one duplicate sample from each
site was analyzed to determine the sampling and analysis precision. Two
samples from each site were analyzed by gas chromatography mass spectrometry
(GC/MS) to confirm the accuracy of compound identification.
-------
Calibration was done with in-house standards made from injections of
D
each neat liquid chemical into a heat-traced tube of a 33-L SUMMMA -treated
canister, purged with zero air and pressurized to a known pressure for
dilution. The calibration gases were hunidified to about 70% relative
humidity. Daily spans of in-house standards were used to determine
calibration factors for quantitation of the target gases. Compound
identification was done using retention time (primarily on the FID) along
with PID/FID and ECD/FID area count ratios. The percentage coefficient of
variation (% CV) of the ratios between the span and the sample for a given
compound were also used to aid compound identification.
Eighteen air toxics compounds were identified ranging in concentration
from just above the detection limit (0.2 to 0.9 ppbv) to 94.8 ppbv.
Compound identification by the GC/MD system was confirmed by GC/MS in 91.4%
of the cases.
Precision in terms of absolute percent differences averaged from
10.5 to 46.4 for replicate analyses of the same sample, and from 2.4 to 23.9
for duplicate sample analyses.

9.0 AIR TOXICS EQUIPMENT
Radian began the study of air toxics compounds in ambient air samples
collected for the Nonmethane Organic Compound (NMOC) Monitoring Program in
1986. For the 1987 monitoring program, NMOC ambient air samples were
collected at 32 sites from 6:00 AM to 9:00 AM at about 15 psig in
6-liter (L) stainless steel canisters. For 15 of the NMOC sites, after NMOC
completion of the analysis, the samples were also analyzed on the GC/MD
system for the compounds listed in Table 10-1. In a related study, Radian
began collecting and analyzing 24-hour ambient air samples at 19 sites. The
latter samples are analyzed for air toxic compound (Table 10-1)
concentrations. The 24-hour samples will continue to be collected and
analyzed through September 1988 and will be reported separately. No 3-hour
and 24-hour sties were co-located in 1987. In subsequent years co-location
of 3-hour samples and 24-hour samples may provide valuable information.
Delivery of the ambient air samples from the canisters to the GC/MD
analytical system involved transferal of the sample from the canister under
0.0 to 10.0 psig pressure for the 3-hour samples, and under
0.5 to 14.0 inches Hg vacuum in the case of the 24-hour ambient air samples.
Radian Corporation developed a sample interface system which reliably
delivers a constant volume of cryogenically preconcentrated ambient air to
either the GC/MD or GC/MS without drying the sample. Figure 9-1 is a
diagrammatic sketch of the sample interface, gas chromatographic
multidetector analytical system, and data transfer system.
The system interface was developed considering contamination, memory
effects, and repeatability. The potential for contamination of the ambient
air samples was minimized by the design and selection of materials of
construction for the interface. The connecting tubing of the interface was
1/8-inch and 1/16-inch o.d. chromatographic-grade stainless steel. Each
routing valve, shutoff valve, and fitting was made of 316 stainless steel.
The preconcentration trap assemblies were constructed of chroma-
tographic-grade stainless steel and filled with 60/80 mesh glass beads.
Daily baseline checks consisted of sampling and analyzing humidified
zero-grade air immediately after calibration. Zero air analyses have shown
the interface system to remain essentially contamination free.

The elimination of compound memory from previous samples was achieved
by the use of heat-traced temperature controlled components. Each part of
the interface which contacted the sample before and after the analytical
trap was temperature controlled. The 8-port gas sampling valve was enclosed
in an oven and maintained at 160°C with an active temperature controller.
Transfer lines were maintained at 160°C with a separate active temperature
controller. The analytical sample traps were heated to over 200°C during
the thermal desorption cycle to remove any residual compounds.
Repeatability has been accomplished by using a high resolution
pressure/vacuum gauge to measure sample loading pressures accurately.
Trapping temperature was set at -185°C, and thermal desorption was
accomplished by using He carrier gas and a ramp-and-soak temperature
controller capable of delivering 25 amperes of electrical current at 120
volts AC to a 1000-watt heater inbedded in a brass block containing the
sample trap. Repeated measurements of calibration standards indicated that
the samples can be delivered at a constant volume with a precision of less
than 6 percent.
D
A VARIAN 3700 gas chromatograph, configured with a PID, a FID, and an
ECD performed the air toxics analyses. A 30-meter DB-624 chromatographic
column separated the target compounds having retention times greater than
that of methylene chloride. Figure 9-2 shows a diagram of the air toxics
multiple detector system. Fused silica was used for the
detector-to-detector connections. Helium was used as the carrier gas.

10.0 RESULTS
Estimated detection limits for GC/MD and total scan GC/MS analytical
systems for target compounds in the Urban Air Toxics Program are given in
Table 10-1. Four pairs of compounds coelute on the DB-624 chromatographic
column and cannot be separated by the GC/MD system --
benzene/1,2-dichloroethane; n-octane/cis-l,3-dichloropropylene;
m-xylene/p-xylene; and styrene/o-xylene. All of these pairs are identified
separately on the GC/MS with the exception of m-xylene and p-xylene which
have the same mass spectra.
Ten 3-hour ambient air samples were taken for air toxics analyses at
each of 15 urban sites. The samples were taken from 6:00 AM to 9:00 AM in
evacuated stainless steel canisters and were at 10 to 15 psig at the end of
the sampling period. The samples were analyzed first for their NMOC content
by the cryogenic preconcentration and flame ionization detection (PDFID)
method, and then for air toxics target compounds by the GC/MD method. Two
samples from each site were also analyzed by GC/MS as confirmations of the
GC/MD analyses.
The appendix contains tables from each site which lists the results
from each sample tested. The tables include data for replicate analyses for
duplicate analyses, and for GC/MS confirmation on 20% of the samples.
Tables A-l through A-15 list the GC/MD analytical results and Tables A-16
through A-30 give the GC/MS results. Table 10-2 summarizes the air toxics
compound identifications for all the 3-hour ambient air samples. Eighteen
of the target compounds, or pairs of compounds (for those that coelute) are
listed in Table 10-2 by the frequency of identification (number of cases),
minimum, maximum, and mean concentrations in parts per billion by volume
(ppbv). The most frequently identified compound was toluene, followed by
m/p-xylene, styrene/o-xylene, and 1,1,1-trichloroethane. Concentrations
ranged from the detection limit to 94.8 ppbv. The data in Table 10-2 do not
include the identifications from the replicate analyses.

Table 10-3 summarizes the GC/MD and GC/MS compound identification com-
parisons into four kinds:
Positive GC/MD - Positive GC/MS;
Positive GC/MD - Negative GC/MS;
Negative GC/MD - Positive GC/MS; and
. Negative GC/MD - Negative GC/MS.
There were 156 cases Positive GC/MD - Positive GC/MS comparisons in
which a compound identified by the GC/MD system was confirmed by the GC/MS
analytical system. The comparisons classified as Negative GC/MD -
Negative GC/MS were also considered as positive confirmations. The total
positive comparisons expressed in percentage was 91.5. Unconfirmed com-
parisons included those compounds that were identified by one of the
analytical systems, but not by the other. They include those compounds
identified by the GC/MD system but not confirmed by the GC/MS (see Table
10-4) and those compounds reported by GC/MS but not identified by the GC/MD
system (see Table 10-5). Most of the positive identifications on the GC/MD
(see Table 10-4) are several times the GC/MS detection limit. On the other
hand, a number of those compounds identified on the GC/MS but not identified
by the GC/MD were close to the GC/MS detection limit in concentration.

11.0 QUALITY ASSURANCE
Daily calibrations are made using in-house standards of 37 compounds
each at 50 ppbv. Care had to be taken in calculating the concentrations of
o-, m-, and p-xylene and toluene because the chloroprene "standard"
contained the xylenes as stabilizing agents and toluene as a contaminant.
p
In-house standards were blended in a 33-L SUMMMA -treated canister at 10
ppmv of each of 37 air toxics compounds in zero grade air that had been
humidified with HPLC-grade water to approximately 70% relative humidity.
Samples from the 33-L canister were used to make up 50 ppbv in-house
standards in 6-L stainless steel canisters for use in the daily calibrations
of the GC/MD system. After each daily calibration, response factors were
calculated for each compound so long as the daily response factors for each
compound was within + 30% of the average calibration factor from previous
calibration data.
Reported concentration was quantified using the response of the FID
detector. Compound identification was done using the retention time and the
ratios of area counts on whichever of the detectors responded to the
compounds. Depending on how many, and which detectors responded, the
compound identifications were classified as high (H), medium (M), or low (L)
confidence level. The uncertainty of the compound identification increased
as the confidence-level went from H to M to L.
Precision for the 3-hour air toxics concentrations data involved two
analyses of the same ambient sample, one sample from each of 15 sites. For
each replicate pair, a mean, a standard deviation (STD), a percent co-
efficient of variation (%CV), and an absolute percent difference was
calculated. The repeated analysis summary statistics are given in the upper
part of Table 11-1. The results do not distinguish between compounds
identified or sampling sites, but are given for different pairs of confid-
ence levels. The confidence level pairs chosen were H-H, in which there
were high levels of confidence in identification for both analyses, H-M,
M-L, M-M, M-L, and L-L. An H-M confidence level indicates a high level of
confidence level for one analysis (whether the first or second analysis) and
a medium level of confidence for the other. An increasing trend is seen in

%CV and absolute % difference when the confidence level moves from H-H
(7.4% CV, 10.5 absolute % difference) to H-M (11.7% CV, 16.5 absolute % difference)
H-H precision levels (7.4% CV, 10.5 absolute % difference), given about with
precisions for the M-M confidence level pair (14.3% CV, 20.2 absolute %
difference) supports the hypothesis that the precision increases with
decreasing confidence level. For the 3-hour air toxics samples the
analytical precision appears to be inversely proportional to the confidence
level for compound identification. As the confidence level decreases (from
H to M to L), the precision appears to increase.
The lower part of Table 11-1 summarizes statistics for duplicate 3-hour
ambient air samples. Sampling and analysis precisions are given in terms of
% CV and Absolute % Differences for the confidence-level pairs shown. As
seen in the replicate pairs discussed above, an inverse relationship is seen
between confidence level pairs and precision, e.g. H-H (6.1% CV, 8.6
absolute % difference) and M-M (9.6% CV, 13.6 absolute % difference). The
same relationship obtains between H-H (6.1% CV, 8.6 absolute % difference)
and H-M (16.2% CV, 22.9 absolute % difference). However, the precisions
involving the low compound identification level, L (H-L, and M-L) do not
appear to follow the same pattern. On the other hand, the number of cases
for the H-L and M-L comparisons is only four each; and therefore, it is felt
that these data may not be representative of a possible trend. Additional
data for these cases would be necessary to confirm or deny the hypothesis
that the precision is inversely proportional to the confidence level (or
directly proportional to the probability of making an error in compound
identification).
Because the duplicate precision includes both sampling and analysis
variability (expressed as precision) and the replicate precision involves
only the analytical error, one would expect the duplicate precision to be
larger than the replicate precision. This relationship holds for H-M and
M-M comparisons but does not hold for H-H and H-L comparisons. These
results will be monitored as more 3-hour data become available to be able to
distinguish between random behavior and actual differences.

16. ABSTRACT
Samples of air were collected at 15 sites-in the U.S. during June through
September, 1987 on weekdays from 0600-0900 hours. Some of the samples were
analyzed for 28 putative toxic compounds by a gas chromatographic, multi-detector
procedure. Verification of compound identify was by mass spectrometer. Data
from all the samples (about 10 per site) are reported. A description of the
apparatus used is given together with results from the QA program also carried
out.
