1.0 SUMMARY AND CONCLUSIONS
This report summarizes the results of sampling ambient air for selected
carbonyl containing compounds in 12 urban centers in the contiguous United
States as part of the Urban Air Toxics Monitoring Program (UATMP).
Formaldehyde, acetaldehyde, and acetone concentrations were measured using
2,4-dinitrophenylhydrazine (DNPH)-coated silica cartridges to collect the
carbonyls for subsequent analysis. Sampling and analysis followed guidance
provided in U.S. Environmental Protection Agency (EPA) compendium method
TO-11. Formaldehyde concentrations ranged from 0.42 to 34.5 ppbv with an
average concentration for all sites of 4.2 ppbv. Site average formaldehyde
concentrations ranged from 1.5 ppbv for Houston, TX (H1TX) to 7.9 for
Washington, DC (W2DC). Acetaldehyde concentrations ranged from 0.37 to
9.5 ppbv, averaging 1.7 ppbv over all 1990 UATMP sites. Site average
acetaldehyde concentrations ranged from 0.76 ppbv at Houston, TX (H1TX) to
2.5 ppbv at Baton Rouge, LA (BRLA). Acetone concentrations ranged from 0.37
to 10.8 ppbv and averaged 1.8 ppbv over all sites. Site average acetone
concentrations ranged from 0.68 ppbv at Houston, TX (H1TX) to 2.9 ppbv at
Chicago, IL (C4IL).
The precision as measured by the mean percent difference over all sites
was near 12% for formaldehyde, near 13% for acetaldehyde, and near 15% for
acetone. At individual sites the mean percent differences ranged roughly from
4 to 30% for formaldehyde, from 7 to 30% for acetaldehyde, and from 8 to 23%
for acetone.
Accuracy was measured as bias from audit samples. For formaldehyde, bias
ranged from -45.1 to 10.6% and averaged -4.6 percent. For acetaldehyde, bias
ranged from -41.7 to 100.0% and averaged -1.2 percent. For acetone, bias
ranged from -53.4 to 100.0% and averaged -4.3 percent. The average percent
difference and biases reported in this study indicate that the sampling and
analytical methodology is repeatable and valid.
Concentration data for formaldehyde, acetaldehyde, and acetone appeared
to be distributed approximately lognormal for sites in the 1990 UATMP.
Average monthly concentrations differed from month to month over all sites and
:a2-045/can.208f
:a.-aonyi 1990 Final Reoort 1 - 1
-------
from site to site. Lowest average monthly concentrations appeared to be in
May while concentrations appeared to peak in the fall months.
Formaldehyde and acetaldehyde concentrations correlate well at all
sites. Little correlation exists between acetone and either formaldehyde or
acetaldehyde.

2.0 INTRODUCTION
The U.S. EPA developed the UATMP Program to help state and local
agencies assess the nature and magnitude of the toxic compounds in the air.
The UATMP sampler collects ambient air samples at urban sites in 6-liter (L)
SUMMA®-treated stainless steel canisters. At the same time, through a
separate heated sample line, ambient air samples for carbonyl compound
analysis are drawn in parallel through duplicate cartridges which trap the
carbonyl compounds from the ambient air.
The UATMP is a companion program to the Nonmethane Organic Compound
(NMOC) Monitoring Program which began in the summer of 1984. The NMOC
Monitoring Program measures the total concentration of organic compounds, with
the exception of methane, but does not speciate organics. The UATMP speciates
38 toxic compounds listed in Table 2-1, primarily aromatic hydrocarbons and
halocarbons. UATMP ambient air samples are collected in 6-L stainless steel
canisters.
The carbonyl cartridges collected at the UATMP sites for 1990 were
extracted and analyzed by the Atmospheric Research and Exposure Assessment
Laboratory (AREAL) of the U.S. EPA at Research Triangle Park, North Carolina,
for formaldehyde, acetaldehyde, and acetone. This report presents the data
summaries and other data assessments for the carbonyl samples collected during
the 1990 UATMP season. The 1990 UATMP season began in March 1990 and ended in
February 1991. The air toxics compounds collected in canisters for the 1990
UATMP season are reported separately.1-2

3.0 UATMP FOR 1990
Brief program descriptions for the air toxics and carbonyl portions of
the UATMP are given in this section. Both the air toxics and carbonyl
programs collected 24-hour integrated ambient air samples on a once every
12-day schedule beginning the week of March 12, 1990. Sampling for the 1990
UATMP was completed on February 23, 1991.
Whole-air ambient air samples were collected in 6-L SUMMA®-treated
stainless steel canisters and on DNPH-treated cartridges at 12 sites shown in
Table 3-1. The table also gives Radian site codes, Aerometric Information
Retrieval System (AIRS) Numbers, and EPA Regions. Additional description of
the sites from the AIRS data base are given in Appendix A.
Carbonyl samples were taken simultaneously with all the UATMP canister
samples. Duplicate cartridges were installed in parallel in a separate heated
sample probe. Ambient air was drawn through the carbonyl cartridges for
24 hours at a constant flow rate. The flow rate, which is in the range of 600
to 1200 mL/min., is measured at each site by the site operator before and
after taking each sample. Carbonyl cartridges are filled with DNPH-coated
silica which reacts with carbonyls in ambient air, trapping them in the
cartridge.
Ozone was removed from ambient air collected in the 1990 program through
the use of an ozone denuder. This ozone denuder was added to the sampling
system after the heated probe to eliminate ozone, which is an interferant with
the DNPH. The use of an ozone denuder in the sampling system resulted in
higher reported formaldehyde concentrations.
The removal efficiency of each ozone denuder was verified prior to, and
at the completion of, the field sampling. The removal efficiency of all ozone
denuders was measured at > 99.9% using 120 ppb ozone test mixture. In
conjunction with the 1990 UATMP program, a comparison of ozone scrubbed and
unscrubbed DNPH cartridges was conducted and are reported elsewhere.3
Three laboratories are involved in the carbonyl cartridge preparation,
distribution and analysis. An independent EPA contractor prepares carbonyl

sampling cartridges in batches. The Radian RTF laboratory obtained the
prepared cartridges for distribution in the shipping boxes containing the
canisters that are sent to the UATMP sites, along with the carbonyl field data
sheet. Radian coordinates the distribution of the carbonyl sample cartridges,
and custody records to the U.S. EPA AREAL for analysis. EPA's AREAL extracts
samples from the cartridges and analyzes these extracts for target compounds.
Radian Corporation reviews the analytical results, summarizes the data, and is
responsible for semi-annual and annual result summaries, which are distributed
to EPA and participating agencies. Figure 3-1 shows the carbonyl sample and
data flow for the 1990 UATMP.

4.0 SAMPLING, ANALYSIS, AND QUALITY ASSURANCE PROCEDURES
Sampling and analysis procedures for the carbonyl samples, along with
the quality assurance procedures used to quantify data quality are described
in this section. Implementing the UATMP involved Radian personnel installing
the sampling equipment for the canister and the carbonyl samples, training
site personnel to operate the equipment properly, observing all the quality
assurance procedures necessary to ensure the integrity of the sample, and
providing appropriate documentation. The site operators' task involved
recognizing problems with sampling equipment and procedures, and notifying
Radian personnel at Research Triangle Park so that appropriate corrective
action might be taken.
4.1 SAMPLING EQUIPMENT AND PROCEDURES
A schematic diagram of the UATMP sampler is shown in Figure 4-1. The
sampler consists of two subsystems, the VOC canister and the carbonyl
cartridge. Each subsystem collects a discrete sample through use of a common
control system. Each sampler subsystem has separate atmospheric inlet. The
ambient air is introduced through an inverted glass funnel and heated
stainless steel probe. The heated probe was maintained at 150°F to prevent
moisture condensation. The carbonyl cartridges are mounted in parallel, so
that the carbonyl samples are collected in duplicate during each sampling
episode. The carbonyl cartridge is a commerically available (Waters Co.)
silica gel Sep-pak® cartridge which is coated with DNPH. The cartridges are
prepared in batches by the laboratory and stored under refrigeration until
shipped to the field.
The carbonyl cartridges are installed in the sample line several days
ahead of the scheduled sample collection. The collection frequency was planned
once every 12 days (30 per year). A 24-hour sample collection period was
utilizied for both the canister and cartridge samples. The carbonyl probe was
purged and heated prior to sample collection period. Each carbonyl cartridge
has a unique serial number which is recorded on the custody records. In

addition to the carbonyl cartridges installed in the sample line, a third
cartridge is sent along in the shipment box as a trip blank. The trip-blank
cartridge is not exposed to air at any time during the shipment or sampling
periods. The trip-blank cartridges were analyzed for formaldehyde,
acetaldehyde, and acetone at the same time the sample cartridges were
analyzed. All trip blanks were analyzed and the results were substracted in
those instances where the analytical result was above the analytical detection
limit (ADL).
The flow rate through each sample cartridge was measured before and
after each collection period by the site operator. The flow rate was measured
with a calibrated rotameter and recorded on a preformatted data sheet. The
volume of ambient air sampled through each cartridge was calculated in the
laboratory based on the field-recorded flow rate measurements.
4.2 ANALYTICAL PROCEDURES
The analytical procedures for carbonyls is given below. Sample
preparation and analyses are performed at the AREAL by EPA personnel. A
sample cartridge is removed from its shipping vial and attached to the end of
a 10-mL polypropylene syringe. Six-mill il iters of acetonitrile are added to
the syringe and allowed to drain through the cartridge into the graduated
centrifuge tube. After the drainage has stopped the volume of extract is made
up to 5-mL with acetonitrile and mixed. A portion of this solution is
transferred to a 4-mL sample vial fitted with a Teflon®-! ined, self-sealing
septum and stored in a refrigerator until used. The TO-11 high performance
liquid chromatography (HPLC) column and elution solvents used for analysis
were modified to decrease analysis time.
The chromatographic separation is done using a 10-cm x 0.46-cm CIS
analytical column with 3-micron particle size preceded by a 5-cm x 0.46 cm CIS
guard column containing 5-micron particles. Typically, 20-mL samples are
injected with an automatic sample injector. The isocratic elution is carried
out with an aqueous solution of 50% H20, 35% acetonitrile, 15% tetrahydrofuran
at 2.5 mL/min. Detector signals from a programmable multiwavelength detector
are collected for 10 minutes at 220, 254, 330, and 360 nanometers (nm). Any
residual sample is eluted from the column in three minutes with 100%
acetonitrile.
The relevant chromatographic peaks determined by acceptable retention
times are integrated and the concentrations calculated using calibration
;32-045/can.208f

curves from standards analyzed the same day as the samples. The 360-nm signal
is used for this purpose. Other wavelengths are used to compute signal purity
by comparing the signal at these wavelengths for standards to the signal for
each sample. Detection limits are determined by a one-sided tolerance
interval around the repeatability of the lowest standard. This procedure was
modified based on experience with the samples. The analysis modifications
optimized sample throughput for analysis of formaldehyde, acetaldehyde, and
acetone. Some other species may coelute with these target compounds using
this HPLC column and isocratic elution approach.
The aldehyde species reported are formaldehyde and acetaldehyde.
Acetone, a ketone, is also reported. All results were reported to Radian in
parts per billion by volume (ppbv) from the EPA AREAL laboratory via floppy
disk. All reported analyses were identified by the unique cartridge numbers.
4.3 QUALITY ASSURANCE PROCEDURES
Quality assurance procedures relative to calibration data for acetone,
formaldehyde, and acetaldehyde are discussed below. Daily quality control
procedures are also discussed. Sampling and analysis precision was determined
from the analysis of duplicate field samples. Sample custody records were
maintained throughout the program. Figure 4-2 shows the multiple page field
data and custody sheet used for the carbonyl cartridges.
4.4. CALIBRATION PROCEDURES
The calibration procedures used for this study followed AREAL standard
operating procedures.
4-4.1 Daily Quality Control Procedures
Daily calibration checks were used to ensure that the analytical
procedures were in control. Carbonyl samples were analyzed in batches of 75
to 100 cartridges throughout the year. Independently prepared audit samples
were analyzed with several batches of field samples. Daily QC checks were
performed each day that analyses were conducted.
4.4.2 Duplicate Sample*
Duplicate field cartridges were installed in parallel in the sample
probe for each sampling episode, as shown in Figure 4-1. The paired average
of the analyses of these duplicate cartridges was used as the average sample
concentration in this report. If one of the field duplicates was broken or

otherwise declared invalid, the analysis of the remaining cartridge was used
as the reported sample concentration. Likewise, if one of the duplicates
showed a concentration above the detection limit and the other duplicate
reported a concentration below the detection limit, the concentration above
the detection limit was reported as the sample concentration.
4.4.3 Trip Blanks
For each pair of carbonyl samples, a trip-blank cartridge was included
in the field site shipment. The blank consisted of a regular DNPH-cartridge
with caps, identical to the sample cartridges. Each cartridge had a unique
serial number for identification purposes. The blank cartridge accompanies
the duplicate sample cartridges on the trip to and from the site, without
removal of the caps on each end of the cartridge. All trip-blank cartridges
were analyzed. If the concentration of an analyte on the sample blank was
measured to be above the detection limit, the concentrations of the duplicate
samples were corrected for the blank concentration.
4.4.4 Precision
Precision was measured as the average standard deviation of the paired
duplicate samples. The relation between precision and mean concentration, and
between absolute percent difference and mean concentration were investigated.
4.4.5 Accuracy
Accuracy was determined by analyzing audit samples prepared by the
Quality Assurance Division (QAD) of AREAL. The audit samples contained either
formaldehyde, acetaldehyde, or acetone, some combination of the compounds, or
none of the compounds.

5.0 RESULTS
5.1 ANALYTICAL RESULTS
Analytical results are presented in Appendices B and C. Concentrations
of formaldehyde, acetaldehyde, and acetone are reported in ppbv, and are
tabulated by site.
Figure 5-1 shows the annual average of the mean concentrations for the
three compounds at each site. Figures 5-2 through 5-13 show the mean
concentrations for the three compounds by sample period. Each of the figures
represents a separate site. For example, Figure 5-2 shows the mean
concentrations for each sample collection period at site BRLA. Data for each
sampling period are shown with the numerical data in Appendix B and C.
5.2 ANALYSIS RESULT STATISTICS
Appendix B gives rudimentary statistics for the carbonyl analyses Each
site is summarized in two tables in Appendix B that correspond to the two data
analysis cases discussed in the following section. Tables B-l and B-2 list
statistics for BRLA, for example.
In Table B-l for BRLA, the first column gives, in compressed format the
date on which the sample was taken. For the first sample taken at BRLA for
example, the sample date is given as "10-JUL-90," which indicates that the
sample was taken on July 10, 1990. The second column in the table shows the
day of the week for the sample date. Weekday Sn, refers to Sunday; M to
Monday; T to Tuesday; etc. ID Numbers listed in the tables of Appendix B refer
to the Radian ID Numbers for the UATMP samples collected on the sample date
The ID Numbers carrying a "D» after the first four digits refers to a UATMP
sample that was taken in duplicate.
Overall averages are given for each mean concentration, percent
difference, and standard deviation column in the tables of Appendix B These
overall averages may be considered to be annual averages, since the time
interval of the study was approximately one year

5.3 ANALYTICAL RESULTS DATA
Appendix C lists all of the analytical data received from the EPA
laboratory. In addition to sample date, week day, and ID NO., the tables show
"Lot," which identifies the lot number of the carbonyl cartridge used in
obtaining the sample. The carbonyl cartridges were fabricated in lots of
about 300 cartridges per lot, and each lot was given a Lot Number in order to
identify it uniquely.
Each table in Appendix C contains the analytical results from the
indicated site. Concentration and purity data are listed for (duplicate)
cartridge 1, and (duplicate) cartridge 2. The choice of which duplicate was
designated as cartridge 1, and which was cartridge 2, was completely
arbitrary.

6.0 DATA ANALYSIS
5.1 INTRODUCTION
The UATMP carbony] data summaries were prepared for two separate,
parallel cases to illustrate how summary statistics and analysis results may
differ according to the method by which mean concentrations are determined.
Cartridge concentrations listed as zero were set to missing and excluded from
further calculations in both cases. When both cartridge concentrations were
reported by the analytical laboratory below the analytical detection limit
(ADL), the mean concentration was set to missing in both cases. In the first
case, hereafter referred to as Case 1, a mean concentration was calculated
from the two cartridge concentrations only when both concentrations were above
the ADL. When one cartridge concentration was above the ADL and the other
cartridge concentration was below the ADL, zero, or missing, the cartridge
concentration above the ADL was reported as the mean concentration. For
Case 2, a mean concentration was calculated similar to Case 1, however, when
one cartridge concentration was above the ADL and the other cartridge
concentration was below the ADL, a value of one-half the ADL was substituted
for the cartridge concentration below the ADL, and a mean was then calculated
from the two cartridge concentrations. If the other cartrdige concentration
was zero or missing, the cartridge concentration above the ADL was reported as
the mean concentration. These two cases were applied to all three compounds.
The ADL chosen for these two cases were the same for formaldehyde,
acetaldehyde, and acetone--0.36 ppbv.
Several statistical summaries and plots were generated to characterize
the carbonyl data. Summary statistics, including the means and standard
deviations of the normal and lognormal distributions; percentiles; and
confidence intervals were calculated by site and over all sites. Box plots
were constructed to visually represent the data distributions. The question
of seasonality in the carbonyl data was addressed by plotting monthly averages
by site to enable a visual determination of potential monthly periodicity of
the concentration data. Intercarbonyl correlations and covariances were
calculated to demonstrate the relationship of the compound concentrations. A
measure of variability and a measure of precision were calculated for each
-52-045/can.20ef
Caroonyi 199C Final fleoort g _ 1
-------
cartridge pair when both cartridge concentrations were above the ADL.
Finally, audit sample results were summarized.
6.2 SUMMARY STATISTICS
Summary statistics were calculated by site and compound, as well as over
all sites for each compound, for both the mean concentrations and for the
natural logarithms of the mean concentrations. The natural logarithms were
considered because air quality data are often more closely lognormally
distributed than normally distributed. These two sets of summary statistics
were calculated for both Case 1 and Case 2, resulting in a total of four sets
of summary statistics for each compound.
The summary statistics were calculated and stored for use in summary
tables by the Statistical Analysis System (SAS®)4 univariate procedure. This
procedure provides a test statistic and corresponding probability for the null
hypothesis that the data examined are normally distributed. For sample sizes
(N) less than or equal to 2000, which is the case for all samples in this
report, SAS provides the Shapiro-Wilk statistic, W, against which to test the
null hypothesis. For testing at the 95 percent confidence level, the null
hypothesis is accepted when the probability of a smaller W is larger than
0.05.
Table 6-1 lists the probabilities for a smaller W for the distributions
of the mean concentrations and for the distributions of the natural logarithms
of the mean concentrations, by compound, for Case 1 and Case 2 . The site
code "ALL" refers to the summary over all 1990 field sites. The sample sizes
for the other sites are still only minimally sufficient to provide meaningful
probability distribution characterizations. The probabilities listed in Table
6-1 support the postulate that the data are more nearly lognormally
distributed than normally distributed. The null hypothesis (normally
distributed data) is accepted for the distributions of the mean concentrations
only 14 times out of 39 for Case 1 and only 16 times out of 39 for Case 2. On
the other hand, the null hypothesis is accepted 31 and 32 out of 39 times for
both Case 1 and Case 2, respectively, for the distributions of the logarithms
of the mean concentrations, i.e., supporting the postulate that the data are
lognormally distributed.

Tables 6-2, 6-3, 6-4, 6-5, 6-6, and 6-7 list the summary statistics by
compound and site. The mean and standard deviation of the normal
distributions are compared to the mean and standard deviation of the lognormal
distribution.5 Some percentiles are also listed to depict the distribution of
the data.
6.3 BOX PLOTS
Box plots were constructed to compare, visually, data distributions
between sites. The box plots for the logarithms of the mean concentrations at
each site for Case 1 are shown in Figures 6-1, 6-2, and 6-3 for formaldehyde,
acetaldehyde, and acetone, respectively. Box plots of the natural logarithms
of the mean concentrations are shown, because, as demonstrated in Table 6-1,
the logarithms of the concentrations are normally distributed.
The top and bottom of the box are called hinges, and are located such
that the lower hinge represents the 25th percentile and the upper hinge
represents the 75th percentile. The median is represented by a line that
splits the box into two pieces (not necessarily in the middle of the box) and
the mean is indicated by a plus ( + ). The F-spread is defined as the
difference between the 75th and 25th percentiles. "Whiskers" extend on either
side of the box where data exist to a distance of up to 1.5 times the
F-spread. Data located between 1.5 and 3 times the F-spread are indicated by
a circle, while data values more extreme than 3 times the F-spread are
indicated by an asterisk (*).
The box plots appear approximately symmetrical which further supports
the postulate that the data are lognormally distributed.
6.4 SEASONALITY
Only a crude analysis can be made of carbonyl seasonality for this
report because several years' data are needed for an accurate representation,
and the carbonyl data set contains just one year's worth of data. However, by
plotting monthly arithmetic mean concentrations by site and over all sites,
and by examining the results from several analysis of variance (ANOVA) models,
the 1990 carbonyl data may be generally characterized.

Figure 6-4 shows monthly overall average concentrations for
formaldehyde, acetaldehyde, and acetone at all sites in the 1990 UATMP.
Figures 6-5, 6-6, and 6-7 display the monthly arithmetic means by site for the
formaldehyde data. Since there is considerable scatter in the total data set,
three plots are needed to minimize overlap between individual sites. The
overall monthly means are shown on all three plots (Figures 6-5, 6-6, and 6-7)
and are displayed using the box symbol.
The formaldehyde plots show a considerable variability between sites;
however, some patterns do emerge. For instance, most sites show a local
minimum concentration in May, and a local maximum concentration in October.
In most cases these are absolute minima and maxima as well. Most sites also
tend to reach another local minima in September.
Since one pair of sites is located in the same city, some additional
comments about Figure 6-7 may be made. The two Washington, DC sites, W1DC and
W2DC, track rather closely throughout the year, although some months show some
separation. Thus, a measure of verification is provided for this city.
Figures 6-8, 6-9, and 6-10 display the monthly arithmetic means by site
for the acetaldehyde data. The acetaldehyde plots show a bit more variability
between sites than the formaldehyde data. However, there is a tendency for
local minima in May and local maxima in August. As with formaldehyde, these
are usually absolute minima and maxima as well. Other local maxima and minima
occur more frequently and sporadically than with the formaldehyde data. The
two Washington sites track closely from month-to-month.
Figures 6-11, 6-12, and 6-13 display the monthly arithmetic means by
site for the acetone data. Acetone maxima and minima usually occur in
different months. One difference between acetone and the other two compounds
is for a local, and usually absolute, maximum concentration in October. The
local maximum found in March for acetone is similar to the local maxima found
in May for acetaldehyde.
The trends generalized from monthly plots of arithmetic means may or may
not be representative of a typical year. However, it does appear that the
time of year as described by month plays a fairly important role in
influencing carbonyl concentrations, as shown by the differences in the
monthly means in the plots. Also, carbonyl concentrations appear to be site
specific as demonstrated by the differences between sites in the plots.

6.5 INTERCARBONYL CORRELATIONS
Table 6-8 lists the product-moment correlations and the covariances
between the mean concentrations of formaldehyde, acetaldehyde, and acetone for
each site and over all sites for Case 1. Differences between Case 1 and
Case 2 were minimal, so only Case 1 results are shown. Formaldehyde and
acetaldehyde appear more highly correlated than either formaldehyde and
acetone or acetaldehyde and acetone.
Figure 6-14 shows the correlation between formaldehyde and acetaldehyde
concentrations, while Figure 6-15 shows the correlation between formaldehyde
and acetone concentrations. Figure 6-16 shows the acetaldehyde-acetone
concentration correlation. The correlation coefficient for the formaldehyde-
acetaldehyde concentration data is 0.8026, whereas for the formaldehyde-
acetone data the correlation coefficient is 0.6154. The correlation
coefficienct for acetaldehyde-acetone is 0.6262. The line drawn in each graph
locates the regression line. The data used for Figures 6-14 and 6-15 include
each analysis, i.e., for Cartridge 1 and Cartridge 2, for each sampling
episode in which the paired data was available.
6.6 PRECISION AND PERCENT DIFFERENCES
Tables 6-9, 6-10, and 6-11 list the summary statistics by site and over
all sites for the absolute percent difference of the cartridge concentration
data. Since the absolute percent difference was calculated only when both
cartridge concentrations were above the ADL, only results from Case 1 are
shown. The absolute percent DIF, a measure of variability, is defined as the
absolute value of the difference between the two cartridge concentrations,
divided by the arithmetic average of the two cartridge concentrations, times
100:
Absolute percent DIF = ABS (X2 - X1)/((X2 + X^/2) x 100
where: ABS indicates the absolute value;
X1 = concentration from cartridge 1; and
X2 = concentration from cartridge 2.
Precision was estimated from absolute percent difference of duplicate
sample analysis. For formaldehyde the absolute percent difference averaged
11.5; for acetaldehyde 13.4; and for acetone 15.1.
The maximum of any of the percent differences derived from the pairs of
cartridge concentrations was 50% or less for six formaldehyde sites, five
acetaldehyde sites, and five acetone sites. The maximum percent difference

was larger than 100% for only two formaldehyde sites and two acetaldehyde
sites. The largest percent difference for any of the acetone sites was less
than 100 percent. These results show good precision, and speak well for the
sampling and analytical procedures. These results are in agreement with the
1989 results, indicating consistency between the two years in terms of
precision.
6.7 AUDIT SAMPLES
Table 6-12 displays the results from the audit samples for formaldehyde,
acetaldehyde, and acetone. Figures 6-17 and 6-18 display bar charts for the
percent differences between the spiked and reported samples for formaldehyde,
acetaldehyde, and acetone. An overall negative bias is evident for all three
compounds in both Table 6-12 and Figures 6-17 and 6-18. This overall negative
bias-was over four times as much for acetaldehyde as it was for formaldehyde.
The bias for acetone was about the same as it was for formaldehyde.
There was an evident trend in the audit results. The audit results are
illustrated graphically in two separate graphs. Figure 6-17 presents audit
data analyzed prior to instrument system maintenance. After the analytical
system maintenance, the audit results improved as indicated in Figure 6-18.
The audit results over the course of the program indicate that the analytical
system was in control and the analytical results valid.

7.0 CONCLUSIONS
Based on the discussion in the data analysis section, the following
conclusions were reached:
1) The mean concentration data for all three compounds are more
nearly lognormally than normally distributed.
2) Mean concentrations varied from month-to-month for all three
compounds, but the variation of acetone concentrations was
somewhat different than the variation of formaldehyde or
acetaldehyde concentrations. This variation did not appear to be
represented by regular cycles. In addition, the monthly
concentrations also appeared to be site specific, particularly for
acetaldehyde. Analysis of variance results indicated that both
site and month played a role in influencing mean concentrations
for all three compounds; however, other unknown factors appear to
have an even greater influence.
3) Formaldehyde concentrations were fairly highly correlated with
acetaldehyde concentrations at all sites. However, neither
formaldehyde nor acetaldehyde concentrations were well correlated
with acetone concentrations. In fact, the correlation
coefficients of formaldehyde and acetaldehyde concentrations with
acetone concentrations were non-significant at some sites.
4) Absolute percent differences and audit samples biases revealed
that the sampling and analytical methodology employed is
repeatable and valid.
5) The use of a denuder in the sample collection system was
determined to remove > 99.9% of the ozone. Therefore, the
formaldehyde results reported here are not negatively biased by
the ozone present in ambient air.

16. ABSTRACT
From Mar^h1990 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 carbonyl samples are
presented in this report.
