                   11.  URBAN AIR TOXICS MONITORING PROGRAM

     The Urban Air Toxics Monitoring Program (UATMP) began in October 1987,
and ended in October 1988.  It was started for the purpose of helping state
and local agencies assess the nature and relative magnitude of their air
toxics problems.  The UATMP consists of three parts:  filter samples to be
analyzed for certain metals and benzo-a-pyrene, cartridges for collection of
carbonyl compounds, and canister samples to be analyzed for 38 gaseous organic
compounds.  All samples were collected simultaneously, i.e., timers were
programmed to start Hi-Vol filters, to start pumps to draw air through the
carbonyl cartridges, and to open a valve to start filling the canister -- all
beginning at midnight on each scheduled day.  Samples were collected every
twelfth day for 24-hour periods.  All samples were returned to Research
Triangle Park (RTP), NC for analysis by appropriate methods.  This volume
reports the results from analyses of the canister samples.  Separate reports
will be issued describing the results from analyzing the carbonyl cartridges
and the Hi-Vol filters.
     From the beginning, the UATMP has been regarded as a screening program.
That is, to assess the kinds of metals and organic compounds 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 metals/substances which were thought to be of
special concern to health professionals at the time.
     Sampling and analytical methods for ambient organic compounds is a very
complex art.  Because the concentration of the materials being sought is in
the parts-per-billion or sub-parts-per-billion region, these methods are
continuously being refined and improved.  The best method for either sampling
or analysis has yet to be found.  The methods used in the UATMP are the best
known at this time.  The minimum detectable limits for the species of interest
are the lowest possible with the methods available.  Those who would like to
have data at even lower detectable levels than are reported in this volume
must wait for future methods.

programs began at four sites in April  1988.   From June through
September 1988, 41 additional  sites collected 3-hour pressurized samples each
day, five days a week.  Volume I reports on that phase of the program.
     Volume II, a companion to Volume I, reports the results of the UATMP
which speciated 38 target compounds from 24-hour ambient air samples at 19
urban locations.
     Section 11 briefly describes the UATMP and summarizes the data by target
compound and by site.  Precision, accuracy, and compound identification
confirmation results are also summarized.  Section 12 gives more detail about
the UATMP data by compound and by site.  Section 13 discusses sampling
equipment and the sample interface system which takes the ambient air sample
from the canister, cryogenically preconcentrates the sample, and injects it
into the gas chromatograph multidetector (GC/MD) or gas chromatograph/mass
spectrometer (GC/MS) analytical system.  Section 14 discusses quality
assurance and quality control procedures and results—calibration, analytical
precision, sampling and analysis precision, accuracy, completeness, compound
identification confirmation, compound carryover in canisters and canister
pressure, data validation, and data records.  Section 15 gives recommendations
for the UATMP which have derived from the  1988 program, and Section 16 lists
references used in both Volume I and Volume II.
11.1 INTRODUCTION
     In the third quarter of 1987, collection of 24-hour ambient air  samples
began at  19 urban sites in the contiguous  United States.  Analysis was
performed at Radian Corporation's Research Triangle Park laboratory for 38
targeted  air toxic organic compounds (see  Table 14-4).  The UATMP samples were
collected on a  12-day schedule beginning the week of September 24,  1987 and
continuing through October 6,  1988.l  Table 11-1 lists  the  1988 UATMP  sites,
along with the  Storage and Retrieval of Aerometric Data (SAROAD) and
Aerometric Information Retrieval System (AIRS) numbers,  and the site  codes
used throughout this  report.
     Table 11-2 shows the distribution  of  valid samples among  the UATMP sites,

analyses,  and the total  number of GC/MD analyses and GC/MS confirmation
analyses.   A total of 118 analyses,  or 20.9% of the total samples, were
analyzed by GC/MS for compound identification confirmation.
11.2 DATA SUMMARY
     This section summarizes the GC/MD analytical  results.  Data for each
sample are tabulated in Appendix A (see Section 13 for a description of the
sample and analysis procedures).
     Data are grouped below in two ways, by compound and by site.  For each
target compound, summary concentrations are given as minima, maxima, and
means, collecting the data from all  19 sites.  Site-specific data summaries
show which target compounds were identified in samples from each site, and
give minimum, maximum, and mean concentrations.
11.2.1    Overall -Data Summary by Compound
     Table 11-3 presents the UATMP target compounds identified for all the
sites.  The number of cases of identification for each compound above the
estimated method detection limit (MDL) is given along with the frequency at
which they were identified.  The frequency of occurrence is expressed as a
percent of the 719 total GC/MD analyses, including replicate and duplicate
analyses.  Toluene and m/p-xylene were the most frequently identified
compounds, while dibromochloromethane was the least, not having been observed
in any of the samples analyzed.  The concentration range for each compound is
given as minimum and maximum, and the average concentration for each compound
identified is given as the mean, expressed in ppbv and ug/m .  In the
penultimate column, the mean is also calculated assuming half the MDL for all
compounds in which no concentration was measured.  In the last column, the
mean is calculated assuming the concentration of these undetected compounds  is
zero.
     Ethylbenzene was not a target compound during the first quarter  (3rd
quarter 1987); therefore, the percent frequency of occurrence was calculated
based on the total of GC/MD analyses for the remaining three quarters only.
During the second quarter (1st quarter 1988), chloroprene could not be
identified due to the inability to obtain a pure chloroprene standard.

Acetylene, propylene, chloromethane, vinyl chloride, 1,3-butadiene,
bromomethane, and chloroethane were identified in the fourth quarter only (3rd
quarter 1988) after a modification in the GC/MD analysis conditions.  The
percent frequency of these seven compounds was calculated using the total
GC/MD analyses in the fourth quarter only.  m-Xylene and p-xylene coelute on
the analytical column used in the GC/MD system, therefore they are reported
together as one identification.  Styrene and o-xylene also coelute and are
reported likewise.  In the first three quarters of the UATMP, benzene and
1,2-dichloroethane coeluted on the FID; however, benzene could be quantitated
from the PID.  1,2-Dichloroethane was quantitated with low confidence by
subtracting the PID response for benzene from the FID response for
benzene/1,2-dichloroethane.  Benzene and 1,2-dichloroethane were resolved on
the FID when the analytical conditions were changed before the fourth quarter.
n-Octane and trans-l,3-dichloropropylene coeluted on the FID during the first
quarter; therefore, during this time period they were reported together.
     Table 11-4 groups the compounds by frequency of occurrence for the UATMP
                                                                        g
samples.  This table is similar to Table 7-3 in Volume I of this report,
which groups compounds in the 3-hour ambient air samples in ranges of
frequency of occurrence.  Frequency of occurrence for some compounds is based
on the identifications in samples collected during a period less than one
year, as discussed previously in Section 11.2.1.  In addition, methylene
chloride could not be identified with certainty in several UATMP samples
because of the presence of acetonitrile which interfered with the analysis.
Nevertheless, many of the compounds in the 24-hour samples fall into the same
                                                                         Q
frequency ranges as the 3-hour air toxics compounds reported in Volume I.
11.2.2    Site-Specific Overall Data Summary
     Site-specific compound identifications by GC/MD, by site code, are shown
in Tables 11-5 through 11-23.  The "cases" column gives the number of analyses
in which the compound was identified at a concentration above its estimated
MDL 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 fourth column of each table.  Means are also computed assuming

half the MDL for all  those species in which no concentration was measured.  In
the last column, means are computed assuming the concentration of these
undetected species is zero.
11.3 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 11-24 for all compounds and all sites.  The "mean"
in Table 11-24 refers to the average concentration for the replicate pair
analysis for a given compound.  The "average" in Table 11-24 is the arithmetic
mean of the concentration means of all replicate pairs.  The range of
concentrations of the means was found to be from 0.04 to 38.18 ppbv.  Because
of the wide range, the precision reported in Table 11-24 gives a realistic
assessment of the performance of the analytical portion of the method.
Statistics are given for the standard deviation, the percent coefficient of
variation, and the absolute percent difference.  The precision results average
14.0% in terms of average percent coefficient of variation and 19.9% in terms
of average absolute percent difference.  These are excellent results combining
the precision for 38 compounds and 19 sites.  These results should be viewed
as a measure of  analytical precision and not the total method precision.
     Sampling and analysis precision is summarized in Table 11-25 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  percent  coefficient of variation and absolute percent difference are
14.5% and 20.5%, 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.
11.4 ACCURACY
     Accuracy  for the  GC/MD analysis was measured in terms of external audits
received from  the Environmental Monitoring  Systems Laboratory  (EMSL), Quality
Assurance Division  (QAD) of the U. S. EPA at Research Triangle Park,
North Carolina.  Seven analytical  audits were conducted in 1988, approximately
one each month  beginning in March  1988.  Both the GC/MD and GC/MS analytical
systems  were  subject  to the audits.

     During the period from Audits 1 through 4,  accuracy (or percent bias) was
frequently greater than 30%.   After comparing the reported audit results to
the actual amounts added to the audit sample, the inaccuracy was attributed to
erroneous calibration concentrations.  The working standards were, at this
time, being prepared in-house from individual pure compounds.  To improve the
accuracy vendor certified (+5%) gas standards were purchased and a dynamic
flow dilution apparatus was developed to generate in-house calibration
standards.  This procedure greatly improved the audit results and brought the
percent bias well within the +30% range.
     For Audits 5, 6, and 7 the biases for the UATMP target compounds
averaged 0.1%, 6.9%, and 4.9%, respectively, for the GC/MD analyses.  Bias
results for GC/MS averaged -0.2%, 6.7%, and 12.3%, respectively.
     Details of the audits are given in Section 14.7.
11.5 GC/MS COMPOUND IDENTIFICATION CONFIRMATION RESULTS
     Compounds were identified by the GC/MD analytical system using a
combination of retention time, photoionization detector/flame ionization
detector  (PID/FID) ratio, electron capture detector/flame ionization detector
(ECD/FID) ratio, and detector specificity.  Compound identification
confirmation was accomplished by analyzing about 21% of the samples by GC/MS
in the full scan and multiple ion detection (MID) modes.  For all the analyses
GC/MS confirmed 86.9% of the compound identifications made by GC/MD analyses.
Confirmation was complicated during part of the program by acetonitrile
interference in the GC/MD analyses related to the aldehyde collection portion
of the sampler for some of the samples.                             . .
     Further discussion of the compound identification procedure  and results
is given  in Section 14.8.

                                12.  UATMP DATA

     The UATMP data were summarized in Section 11 by target compound and by
site code.  Appendix A contains the results of each analysis.  This section
will discuss some of the trends which appear in the 1988 data.
12.1 OVERALL RESULTS
     In Table 11.3, the compounds identified for all sites were presented
along with the percent frequency at which they were identified.  Table 11.4
further groups the compounds by their range of frequency of occurrence.
Benzene, toluene, and m/p-xylene were among the compounds identified in 100%
to 70% of the UATMP samples.  A closer look at the actual frequency of these
three compounds reveals that while toluene and m/p-xylene occurred at a rate
of 93.8 and 93.5 percent, respectively; benzene was identified in only 71.3
percent of cases.  At this time, the reason for this trend is not apparent.
12.2 SITE-SPECIFIC RESULTS
     Benzene, toluene, and m/p-xylene (BTX) were identified at all the UATMP
sites more frequently than other target compounds.  Figure 12-1 is an example
of how the concentrations of these three compounds changed from October 1987
through September 1988 for Birmingham, Alabama (BHAL).  The BTX concentration
changes in BHAL are typical of the changes seen in the other site data for
these compounds.  The 24-hour concentrations of toluene and m/p-xylene track
one another well and are about equal.  The concentration of benzene is
consistently lower than toluene and m/p-xylene.  Three general patterns of
behavior can be identified in Figure 12-1.  From October 1987 through about
March 1, 1988, BTX concentrations are quite variable, averaging 4 to 6 ppbv.
From about March 1 through about May 1, the concentrations are roughly
constant at an average of about 1.0 ppbv.  From about May 1 through September
1988, the BTX concentrations track each other well, around 2.0 to 3.0 ppbv,
and show moderate variability.

     Similar graphs are shown in Appendix B for all  UATMP sites, including
BHAL, and all display the same three patterns discussed above.  The period of
time between October 1987 and March 1988 may show more variability than later
data because the GC/MD analytical methods were still being improved during
that time.  The data after March 1988 show much less variability from sample
to sample and are representative of the ambient air samples at the UATMP sites
during the later period of time.
     The March 1 through May 1 time period of especially low BTX
concentrations seems to vary from site to site, but is still identifiable.
No reason for this trend in the data has been identified.

operation and certification; the sample interface, which takes a sample from
the canister for injection into the analytical  equipment; the generation of
calibration standards; and the analytical equipment and procedures.
Compound identification procedures are detailed,  along with the GC/MS compound
identification confirmation procedures.  Finally,  the UATMP canister cleanup
procedure is described briefly.
13.1 SAMPLING EQUIPMENT
     A perspective view of the UATMP sampler is given in Figure 13-1, while
Figure 13-2 shows the detailed layout of the sample lines, flow controllers,
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 ambient air 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 Mobile Source
Branch onsite contractor and sent to Radian Corporation's Research Triangle
Park 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 for analysis to the EPA Environmental  Monitoring Systems
Laboratory (EMSL).  The aldehyde results will be reported in a separate
report.
     The UATMP samplers were set to begin drawing air through the  sample inlet
and sample lines about 6 hours before the it 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
purged with ambient air.  The sample flow rate into the 6-L canister was
controlled at approximately 3.5 mL/minute.  The resulting pressure in the
canister after 24 hours was approximately 1.0 to 5.0 inches mercury (Hg)
vacuum.  Section 14.5 presents and discusses the actual canister pressure
distribution after the canisters were received in Radian Corporation's
Research Triangle Park laboratory.   The method of sampling operated on a
slip-stream approach with the canister under vacuum (about 29.72 inches Hg
vacuum) to avoid potential contamination from the pump.
13.1.1    Sampler Certification Blanks
     Before the samplers were installed at the UATMP sites they were certified
in Radian Corporation's Research Triangle Park laboratory.  Certification
consisted of purging the sampler with cleaned, humidified air, followed by
collecting a sample of the cleaned, dried air that had been humidified through
the purged UATMP samplers for GC/MD analysis.  The purpose of the wet purge
was to help remove any adherent contaminants from the  sampler.   The
chromatograms  from these certification sample analyses were archived for each
sampler.  Few  target compounds, or other  interfering compounds, remained in
the gas stream after purging.
13.1.2    Sampler Certification Selected  Target Compound Challenge
     Following the UATMP  sampler blank certification,  a challenge gas
containing eleven selected target compounds was passed through three of the
samplers, chosen at random.  The three samplers used were Sampler No. T-21,
Sampler No. T-ll, and  Sampler No. T-10.   The collected challenge gas samples
were analyzed  by GC/MD.   The average concentration of  the target compounds  in
the challenge  gas was  12.2 ppbv.
     Table  13-1  shows  the percent bias calculated with the analysis  of  the
challenge gas  being used  as  a reference concentration.  Percent bias ranged
from  -10.4%  for  chlorobenzene  (from Sampler No. T-ll)  to +135.3% for

average biases ranged from 3.7% for Sampler No.  T-ll to 30.9% for Sampler
No. T-ll.  These samplers were assumed to be representative of all the UATMP
samplers, and average bias in the range of about +30% was considered
satisfactory.
13.2 SAMPLE INTERFACE SYSTEM
     Figure 13-3 shows the UATMP GC/MD system which includes the Sample
Interface System, the Analytical System, and the Data System.  Figure 13-4
diagrams the sample interface system.  The upper part of Figure 13-4 shows the
configuration of the interface system valve for the loading of sample through
Trap 1 in which the sample is condensed (trapped) by being immersed in liquid
argon.
     The lower part of Figure 13-4 shows the sample interface system valve in
the position for injecting the cryogenically trapped sample into the gas
chromatograph.  In the latter mode, the argon is removed from the trap, and
the trap is heated.
     The sample interface takes a constant volume sample of about 250 ml from
the sample canister and  preconcentrates the sample by cryogenic trapping (see
Load Trap  1  in Figure 13-4).  Following sample preconcentration, the 8-port
sampling valve is placed in  the inject position  (Inject Trap 1 in Figure 13-4)
and the  sample trap is rapidly  heated.  Helium carrier gas transports the
trapped  sample directly  onto the head of the column.
      Initial calibration of  the GC/MD system showed that the sample interface
system provided a consistent sample volume with  a precision  (coefficient of
variation) of less than  3 percent.
13.3  CALIBRATION STANDARDS  GENERATION
      Calibration standards  were generated with a dynamic flow dilution
apparatus.   The flow dilution system  used certified gases  and diluted them
with  zero-grade air that had been routed through a  catalytic oxidizer and then
humidified with HPLC-grade  water.  The gases were mixed  in  a SUMMA®-treated
mixing sphere  and  bled  into evacuated canisters.  One  dilution  stream was
routed through  a SUMMA*-treated bubbler  containing  HPLC-grade water to
humidify it,  and the other  stream was not humidified.  The dilution air
streams  were then  brought together for mixing with  the streams  from three

certified cylinders.   Flow rates from all  four streams (three from the
certified cylinders,  and one from the dilution cylinder) were gauged and
controlled by mass flow controllers.  The split air dilution streams were
metered by "wet" and "dry" rotameters from the humidified and unhumidified
dilution air streams respectively.
     The system was evacuated with a vacuum pump while the closed canister was
connected.  A precision absolute pressure gauge measured the canister pressure
before and after filling.  The lines leading to the canister and to the mixing
sphere were flushed for at least 15 minutes with standard gas before being
connected to the canister for filling.  A diagram of the apparatus is shown in
Figure 13-5.
13.4 ANALYSIS
     UATMP samples were analyzed for 38 target compounds by the GC/MD system.
Having simultaneous detector responses from ECD, PID, and the 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.  Over 20% of the UATMP samples
were also analyzed for compound identification confirmation by GC/MS operating
in the full scan or MID mode.
13.4.1    GC/MD Instrumentation
     The gas chromatograph used with the multidetector  system was a
VARIAN 3700.  Table 13-2 gives the  GC/MD operating conditions.  Figure  13-6
shows the multiple detector system  arrangement.
     The oven,  which contains the DB-624 capillary column,  is cooled to  -30°C
with liquid nitrogen at the beginning of the sample injection.  The -30°C
temperature is  held for 1 minute  and then the temperature  is increased  at the
rate of 3°C per minute to a final temperature of 180°C.  The gas eluting from
the DB-624 capillary column goes  through a  1:10 fixed splitter which divides
the flow to the ECD and the PID/FID.  The smaller gas stream from the splitter
goes to the ECD, while the larger fraction  goes first to the PID and then the
FID.
13.4.2    GC/MS Instrumentation
     One hundred eighteen UATMP samples were analyzed by GC/MS using a
FINNIGAN OWA 1050  and 4510 operating  in the full scan and  MID mode.  The full

scan mode was originally used to detect unknown compounds.  The MID mode was
subsequently used to obtain more sensitivity which lowered the estimated MDLs.
In order to make the instrument sensitivity (and MDLs) approximately
equivalent to the sensitivity of the GC/MD system, a 500-mL sample (at room
temperature and barometric pressure) was taken by the GC/MS sample interface
system.
13.5 CANISTER CLEANUP
     The sample canister cleanup system used for the 1988 UATMP is the same as
the one described in the 1988 Quality Assurance Project Plan (QAPP) and the

1988 NMOC Monitoring Program.     The canister cleanup system is shown in
Figure 13-7.  The canister cleanup procedure used for the UATMP sample
canisters was the same as the cleanup procedure for the NMOC canisters, and
                                                          g
was described in Section 3.3.2 of Volume I of this report.
     A bank of eight canisters was connected to each manifold shown in
Figure 13-7.  The valve on each canister was opened, with the shutoff valves
and the bellows valves closed.  The vacuum pump was started and one of the
bellows valves was opened, drawing a vacuum on the canisters connected to the
corresponding manifold.  After reaching 5 mm Hg absolute pressure as indicated
on the absolute pressure gauge, the vacuum was maintained for 15 minutes.  The
bellows valve was then closed and cleaned, dried air that had been humidified
at about 80% humidity was introduced to the evacuated canisters until the
pressure reached 20 psig.  The canisters were filled from the clean air system
at the rate of 6.0 L/min.  This flow rate was 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 had completed the evacuation phase and was being
pressurized, the second manifold was then subjected to vacuum by opening its
bellows valve.  After 15 minutes,.the second manifold was isolated from the
vacuum and connected to the clean, dried air that had been humidified.  The
first manifold of canisters was then taken through a second cycle of evacua-
tion and pressurization.  Each manifold bank of eight canisters was subjected
to two cleanup cycles.

     During the second cleanup cycle,  the canisters were pressurized to
20 psig with clean, dried air that had been humidified.  For each bank of
eight canisters, the canister having the highest precleanup NMOC concentration
was selected for NMOC blanking analysis to determine potential hydrocarbon
residues.  If the analysis measured less than 0.030 ppmC, then the eight
canisters on the manifold were considered clean.  Finally the canisters were
again evacuated to 5 mm Hg pressure absolute, capped under vacuum, and then
packed in the containers used for shipping to the field sites.

         14.   QUALITY ASSURANCE/QUALITY CONTROL PROCEDURES AND RESULTS

     This section describes the quality assurance (QA) and quality control
(QC)  procedures and results for the 1988 UATMP.  During this time period the
sampling and  analytical  methods for the measurement of 38 target compounds in
ambient air in the range of about 0.1 to 10 ppbv were still being qualified
and refined.   The methods described in this report and the results presented
represent state-of-the-art technology.  In the Quality Assurance Project Plan
for the 1988  UATMP, few quality objectives could be specified because the
technology for sampling and analysis had not been demonstrated prior to this
program.  The quality results of the 1988 UATMP provide a basis for setting
quality objectives for future UATMP.  Sampling and analytical procedures and
QA methods will continue to be refined and improved, but as the following
sections will show, the quality of the results of the 1988 UATMP is excellent
and the program has provided reliable data for 38 air toxics target compounds.
14.1 INTRODUCTION
     The primary quality assurance objectives for the 1988 UATMP include
completeness, precision, and accuracy.  In addition, compound identification
confirmation  procedures, sample custody procedures and records were developed.
Canister pressures and their distribution demonstrated the effectiveness of
the sampler operation and equipment.
     Carryover of target compounds from one sample canister to the next was
investigated  to indicate the effectiveness of the canister cleanup procedure.
Other topics  covered in this section include calibration and analytical method
detection limits, data validation procedures, and program record storage and
accessibility.
14.2 CALIBRATION AND INSTRUMENT PERFORMANCE
     The GC/MD analytical system uses one column and three detectors.  The
detectors received sample components after gas chromatographic separation by
splitting the sample 1:10.  The smaller fraction (10%) from the effluent goes
to the ECD.  The larger fraction (90%) goes to the PID, which is in series
with FID.

-------
The analog signal from each of the detectors is converted to digital data by a
Nelson analog-to-digital (A/D) interface.  The digital information is
automatically sent, either real time or post run, to a microcomputer where it
is processed and stored on fixed disk.  Four ASCII files are created by the
software; they are the method file (.MET), the header file (.HDR), the raw
data file (.PTS), and the area table file (.ATB).  In addition, an external
standard area file is generated from header and raw data information from
analysis of standards.  The area table file includes header information, peak
number, retention time, peak name, concentration, peak area, peak height, peak
area/height ratio, the reference peak number for the named peaks, delta
retention time,  and response factor.
     Calibration gases are generated by dynamically diluting gas streams from
certified (+5% accuracy) cylinders containing the 38 UATMP target compounds
obtained from .Scott Specialty Gases,  Inc.   In-house standard calibration gases
are generated by the  flow dilution apparatus and stored  in SUMMA®-polished
stainless steel  canisters.  The initial  instrument calibration range was 1.0
to 20  ppbv for each of the target compounds.  Daily calibration was done with
in-house standards made from the Scott certified gases with average
concentrations of  10  ppbv.
     All the calibration data were used  to  calculate calibration factors for
each UATMP target  compound.  These calibration factors were used for
quantitation.  Tables 14-1 through 14-3  summarize the calibration factors  for
the FID, PID, and  ECD,  respectively.  The FID calibration  factors were  used
for quantitation of the majority of compounds, with the  exception of the
halogenated compounds.  The ECD calibration factors were used  in most cases of
halogenated compound  quantitation due to its greater  sensitivity  at  low
concentrations.
      Estimated method detection limits  (MDLs) for the GC/MD and  GC/MS
analytical systems are given  in Table 14-4.  These MDLs  were  achieved using a
sample size for  the GC/MD  of  about 250 ml,  at laboratory temperature and
pressure.  These detection limits were estimated  for  both  GC/MD  and  GC/MS
using  an area  count that  could  be detected  on the FID and  ECD  and multiplying
 it by  the  response factor  for each compound.  These results are  approximately
three  times the  instrument noise  level.   In order to  make  the  sensitivity  of

 Detection limits estimated using minimum detectable  area count and response
 factor for each compound.   These estimates  are  approximately three times the
•detection noise level.
 GC/MS operated in the full scan mode in  the first  quarter;  thereafter GC/MS
 operated in the MID mode.

the GC/MS similar to that of the GC/MD, the sample size was increased to about
500 ml, and the GC/MS was operated in the MID mode.
14.3 ANALYTICAL PRECISION FROM REPLICATE ANALYSES
     Analytical precision was estimated by replicate or repeated analyses of
selected UATMP ambient air samples.  Table 14-5 shows precision statistics
overall and on a quarterly basis.  "Mean" in Table 14-5 refers to the average
concentration of the replicate pair,  and is tabulated over all compounds.  The
quarterly mean concentration values ranged from a high of 3.49 ppbv in the
third quarter 1987 to a low of 0.91 ppbv in the second quarter of 1988.  The
average absolute percent 'difference for all UATMP compounds in all samples was
19.80 percent.
     The replicate statistics by compound are shown in Table 14-6.  The table
shows that the mean absolute percent differences above 40% occur with
compounds having six, or fewer, replicate pairs.  The absolute average percent
difference appears as a function of average concentration in Figure 14-1.  The
graph clearly demonstrates that the imprecision increases dramatically below
5 ppbv for all compounds.
14.4 SAMPLING AND ANALYSIS PRECISION FROM DUPLICATE SAMPLES
     Sampling and analysis precision was measured by analyzing duplicate
samples taken simultaneously at each UATMP site.  The absolute percent
difference for all duplicate samples averaged 20.52%, which is larger than the
replicate analysis precision (-19.80 percent).  This is expected because the
statistics for duplicate samples include sampling and analysis error, whereas
the replicate precision includes only analytical error.  Duplicate sample
statistics for the 1988 UATMP are summarized in Table 14-7.
     Table 14-8 shows the duplicate sample precision statistics by compound.
Figure 14-2 plots the duplicate sample imprecision as a function of the
average of the duplicate pair concentration.  The same general trends appear
among the results shown in Table 14-8 and Figure 14-2 as were seen for the
replicate analyses.  Below 5 ppbv the variability for the duplicate samples
increases significantly.
14.5 EXTERNAL AUDIT RESULTS
     The results are summarized in Tables 14-9 through 14-14 for external
audits 5 through 7.  Audit samples were analyzed both by GC/MD and GC/MS.

The audits began in March 1988 and were supplied by the U.S. EPA, EMSL, QAD.
During the period from Audit No. 1 through Audit No. 4, accuracy, or percent
bias, was frequently greater than 30 percent.  The inaccuracy was identified
as a problem with the in-house working standard preparation.  All GC/MD data
obtained during this period were corrected for the inaccuracy by using
correction factors based on the agreement between certified gas standards
prepared by dynamic flow dilution and the response factors used during the
time period in which Audits 1 through 4 were analyzed.
     Beginning with Audit No. 5, Radian used a flow dilution apparatus and
certified gas standards to generate in-house standards.  This procedure of
standards generation greatly improved the accuracy in audit results, and
brought the percent bias well within the +30% range.
14.6 GC/MD COMPOUND IDENTIFICATION CONFIRMATION
     GC/MD compound identifications were confirmed using GC/MS.  A
contributing factor that possibly decreased the percent confirmation was the
mode in which the GC/MS was operated.  In the first quarter the GC/MS was
operated in the full scan mode and subsequently in the MID mode for the UATMP
target compounds.  Another factor was that there were frequent lapses of
several days between the GC/MD analyses and the GC/MS analyses of the same
ambient air sample.  This time period may be significant because adsorption
equilibria may cause a compound which was not identified by GC/MD analysis, to
be  identified by GC/MS or vice versa.  This adsorption equilibrium phenomenon
is  particularly critical if the compound is identified near the estimated
detection limit of either GC/MD or GC/MS.  A third factor influencing
confirmation was the discovery of an interfering compound (acetonitrile) used
in  the aldehyde collection portion of the UATMP sampler.  The presence of this
compound obscured the GC/MD results for methylene chloride  in some samples.
The GC/MS analysis was not affected, thus allowing GC/MS to identify compounds
that were not identified by GC/MD.
     Subsequent to the discovery of the contaminating  acetonitrile from the
aldehyde cartridges, separate  sampling lines were installed for  the aldehyde
cartridges  and  the UATMP canister samples.  Thereafter, the acetonitrile

interference with the UATMP samples was eliminated.  The results are
summarized in Table 14-15 and show an overall  confirmed identification rate of
86.7 percent.  A "confirmed" identification included those compounds that
either were identified or were not identified by both GC/MD and GC/MS.
     The MID mode was used to enhance sensitivity for target compounds.  Full
scan was used only when the GC/MD chromatograms indicated a need to identify
unknown compounds.
14.7 COMPLETENESS
     Completeness was measured in terms of the percentage of the scheduled
samples that resulted in a valid sample analysis by GC/MD.  Table 14-16 shows
the completeness quality statistics.  Completeness ranged from 88.2% at
C4IL/C5IL to 100% at 7 (of the 19) UATMP sites.  This is an excellent record,
considering the complexity of the sampling apparatus and the fact that this
was the first year of the UATMP.  Table 14-17 lists the voided samples.
14.8 CANISTER CLEANUP QUALITY AND COMPOUND CARRYOVER
     Compound carryover in canisters was estimated by analyzing the canisters
using GC/MD immediately after the cleanup procedure and again after
approximately 16 hours of equilibration.  The canisters were cleaned using the
                                                           g
procedure described in Section 3.3, Volume I of the report,  with the
exception of pulling the final 5 mm Hg vacuum on the canisters.  The
pressurized humid air canisters were bled to ambient pressure prior to GC/MD
analysis.  The total organic compound concentration was estimated for both
analyses by using the calculated ppbv for all  peaks in the chromatogram.
Target compounds that were identified were noted.
     Table 14-18 estimates the compound carryover in canisters based on the
initial analysis of cleaned, dried air that had been humidified in the
canister and again about 16 hours later.  The table shows the distribution of
the compounds identified along with the tally.  The discrepancy in the tally
for both columns indicates that the compound was not identifed at a
concentration above the estimated method detection limit in one or both of the
analyses.  The average concentration of UATMP target compounds identified in
the first sample analyses was 0.12 ppbv.  For the second analyses, the average
compound concentration was 0.16 ppbv.

The increase in average target compound concentration is about 30 percent.
The total or cumulative concentration for all compounds detected in the first
analyses was 25.6 ppbv.  The total or cumulative concentration for all
compounds detected in the second analyses was 30.5 ppbv.  The average increase
in the total organic compound concentration after the 16 hours equilibration
was 23.6 percent.
     Figure 14-3 plots the concentration ratio data for each canister versus
the NMOC concentration prior to cleanup.  There are insufficient data in the
graph to note any trends at this time.  These studies show that there is a
measurable amount of UATMP target compounds remaining in the canister after
cleanup.  The data suggest that there is an equilibration period which may
result from adsorption equilibrium phenomena between compounds in the gas
phase and the interior surfaces of the canister walls.  The paucity of the
data does not allow firm conclusions, but shows the need for further  study to
determine the magnitude of the change and the equilibration time necessary to
generate more precise data.
14.9 CANISTER PRESSURE RESULTS
     The canister pressure was measured immediately prior to withdrawing  a
sample from the  canister for analysis using a precision absolute pressure
gauge.
     Absolute canister pressures, including pressures for duplicate canisters
and canisters for which replicate analyses were performed, are plotted in
Figure  14-4.  The figure is a stem-and-leaf plot  showing all the data and
indicates a frequency distribution.   The pressure has been corrected  'to
standard conditions of zero degrees  centigrade  (0.0°C).  Pressure ranged  from
286.3 mm Hg at  the top of the stem-and-leaf plot, to  745.7 mm Hg at the bottom
of the  plot, and averaged 636.1 mm Hg.  Other statistics are shown on the
figure.  The distribution appears to be binodal,  having a peak around
399 mm  Hg,  and  again  around 711 mm Hg.
     The pressure distribution data  indicate a  wide  range of absolute pressure
collected by the UATMP 24-hour samplers  -- 301.9  mm  Hg  (-18.0  in. Hg  vacuum)
to 740.6 mm Hg  (-0.76  in. Hg  vacuum).   The results show that the site
operators were  not able to maintain  a target value of 1.0 to 3.0 in.  Hg vacuum
as the  final sampling  pressure.

     The canister absolute pressure data,  excluding duplicate samples, are
plotted in Figure 14-5 and show a pressure range from 301.9 to 740.6 mm Hg.
The binodal nature of the frequency distribution is not as pronounced as in
Figure 14-4; but it still remains.  This comparison shows that, although the
duplicate samples are significantly responsible for the binodal frequency
distribution, other unknown factors also contribute to this phenomenon.  That
is, elimination of the duplicate sample measurements does not eliminate the
node around 390 mm Hg.  The reason for the binodal pressure distribution is
not known.
     Table 14-19 gives, by site,- the average canister pressures at the time of
the GC/MD analyses.  The average pressures range from 1.42 in. Hg vacuum
(about 728.5 mm Hg absolute) from the Houston, Texas site to 9.18 in. Hg
vacuum (about 526.8 mm Hg absolute) for the Jacksonville, Florida site.  The
standard deviations range from 0.89 in. Hg vacuum"at the Houston, Texas site
to 5.9 in. Hg vacuum for the Jacksonville, Florida site.  It is clear that the
average sample pressures differ significantly from site to site, as do the
standard deviations.  The differences are probably caused by a combination of
site operator differences from one site to another, and the sampler
differences from site to site.  It is important to monitor the canister
pressures to ensure collection of a UATMP sample that is valid.  It is
necessary for the sample to have some vacuum remaining in the canister, at
least 0.5 in. Hg vacuum, to be sure that a 24-hour integrated sample was
obtained.  If the vacuum is less than 0.5 in. Hg vacuum, at least part of the
sample was obtained at a slower rate than the first part of the sample;
therefore, the whole sample is not truly representative of a 24-hour
integrated sample.  If the vacuum in the canister is much lower than about
10 in. Hg vacuum it requires a longer time for the sample interface to load a
sample from the canister for analysis and the imprecision of the sample volume
increases.
14.10     DATA VALIDATION
     A Nelson Chromatography Data System was used to acquire UATMP
chromatography data.  Responses from each detector are received by two Nelson
A/D interfaces which transfer the data to a microcomputer.  The Nelson raw
data files and area table files for each sample are stored directly to a

20-megabyte (mb) removable cartridge Bernoulli disk.  These data are backed up
with additional 20-mb Bernoulli cartridges and subsequently on magnetic tape
for permanent storage.  The area table files are processed by a peak
identification program written in "C" language.  The peak identification
program uses PID/FID and ECD/FID ratios, average response factors, and
retention time windows to identify target compounds.  This program
compares the sample ratios for each compound to those of an average calculated
calibration standard.  The percent coefficient of variation is calculated
between the sample compound ratio and that of an average standard and is used
as a criterion for identification.  The peak identification program also uses
the average retention time for toluene as a reference with which to compare
retention times for compounds in the sample.  Compounds responding on only one
detector must be identified by retention time and the absence of response on
the other two detectors.  When a compound identification is made by the
program, it calculates the concentration in ppbv based on an average standard
response factor for the corresponding compound for each detector.  Each sample
chromatogram is reviewed, using the Nelson data system, and compared to the
peak identification.  The verified data are then entered into a cumulative
database using  Paradox® software and also into data summaries using Lotus®
1-2-3  software.  The database and data summaries are finally checked for data
entry  accuracy  and completeness before statistical calculations are performed.
14.11     DATA  RECORDS
     The data  records for UATMP include field sampling information, laboratory
receipt and analysis  information, and processed data obtained for 38 target
compounds for  719 GC/MD analyses and 118 GC/MS analyses of UATMP  samples, plus
daily  checks,  audits, and other QA/QC samples.
     The field  data  sheets that accompany each canister to the  sampling sites
are completed  by the  site operators  and laboratory personnel upon receipt.
These  data  sheets are bound  and kept in the laboratory and pertinent field
data are recorded on  magnetic  disks.  Each  sample is assigned a unique
 identification  number upon receipt  in the laboratory.  This  identification
 number appears  on the field  data  sheet, chromatogram, Nelson chromatography
data files,  in  the cumulative  database  and  data  summary.   Nelson
 chromatography data  for each UATMP  sample are  stored directly to  a  20-mb

removable cartridge disk.  These primary data disks are backed up daily to
20-mb removable cartridge disks and are finally archived to 20-megabyte tapes.
The hard copy chromatograms are stored in file folders by date.
     A daily analysis log is kept as a means of tracking date and conditions
of analysis.  The analyst also records information in a laboratory notebook as
needed.  Following the identification process and data verification, the
results for each sample are entered in a cumulative database using Paradox®
database software.  For reporting purposes these data are also entered in a
LOTUS* 1-2-3 spreadsheet data summary.

                             15.  RECOMMENDATIONS

     The following recommendations derive from experience with the 1988 UATMP.
During this program a significant amount of method qualification and
modification was necessary.  Much progress was made and the data obtained
reflect the very best canister technology that is available today.  Additional
development is needed to better define precision and accuracy, especially at
levels near the estimated MDLs for the target compounds.
15.1 CANISTER CLEANUP AND STABILITY STUDIES
     Although preliminary studies indicated that the average concentration of
target compounds carried over in canisters was < 0.2 ppbv, canister cleanup
studies are important to relate the amount of compound carryover in canisters
one may expect to observe from one sample to another.  Canister cleanup
studies can also be used to evaluate canister cleaning strategies for the
UATMP.  Canister stability studies aid in the determination of how
representative the canister sample is of the orginal ambient air that has been
sampled.  It is recommended a canister cleaning study and canister stability
study be performed to evaluate these important issues.
15.2 UATMP FIELD AUDIT
     It is recommended that a field audit procedure for UATMP samplers be
developed and implemented for the target compounds.  The need for the field
audit procedure relates to canister cleanliness and to the reaction and
adsorption equilibria which occur in a canister after an ambient air sample is
taken.  A proper field audit is the only approach which will test the entire
UATMP method accuracy.
     One benefit of the field audit procedure would be determining the
magnitude of chemical reaction and adsorption that occurs when an ambient air
sample is collected in a clean canister.  Another benefit would be
determining if a difference in concentration can be detected between a heated
stainless steel sampler probe compared to an unheated probe.

-------
     Once the UATMP field audit procedure is developed, semiannual field
audits are recommended.   It is also recommended that bimonthly external
analytical audits at two different concentration levels be continued in the
1989 UATMP.
15.3 METHOD DETECTION LIMIT STUDY
     It is recommended that further MDL studies be conducted for the UATMP
target compounds using both the GC/MD and the GC/MS analytical methods.
During the course of the 1988 UATMP, estimated MDLs were determined for the
GC/MD and GC/MS in the MID mode.
     The method outlined in the Federal Register   is recommended for both the
GC/MD and the GC/MS (in the MID mode) for the 38 UATMP target compounds.
     The results should also be processed using specified assurance
probabilities recommended in Reference 11.  The assurance probabilities
recommended in Reference 11 specify probabilities of Type I and Type II
errors.  Type I errors relate to reporting an analyte as present when  it is
not, and Type II errors relate to reporting an analyte as absent when  it is
present.  The Federal Register MDL   method sets a 95% probability against a
Type I error, but results in a 50% probability of a Type II error.
     Reference 11 permits setting 95%  (or any other percent) probabilities for
both type errors, and although it results in a higher MDL,  it also gives a
more realistic definition of the analytical risks involved  in the compound
identification.  Using both the EPA  (Federal Register) and  Reference 11
approaches will allow a set of working and a set of conservative  MDLs  to be
generated  for both the GC/MD and GC/MS analytical systems.
15.4  INTERNAL STANDARD FOR GC/MS ANALYSES
     Use  of  internal standards  is recommended for GC/MS  analyses  for the 1989
UATMP.  The  internal standards would be  injected into  both  calibration  samples
and ambient  air samples.  The  use of internal standards  requires  modification
of the  sample interface system  for  the GC/MS.  A suggested  internal standard
gas would  contain:

           dg-toluene
           d.-l,2-dichloroethane
 cah.119                               15-2

-------
          d,Q-ethylbenzene
          dg-chlorobenzene
          perfluorotoluene
          perfluorobenzene
          1,4-di f1uorobenzene
The use of internal  standards will  increase the accuracy of all the GC/MS
analyses.   Modification of the current interface is underway to permit use of
internal standards in GC/MS analyses in 1989.
15.5 REPLICATE AND DUPLICATE ANALYSES
     It is recommended that all the replicate GC/MD analyses for the UATMP be
done on the duplicate samples if canister pressure allows.  This approach will
allow separation of sampling and analytical precision.

16. ABSTRACT
      From October, 1987 to October,  1988 samples of ambient air were  collected at
 19 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.
