SECTION 1
INTRODUCTION
During the past several years, research has been conducted on the
development of a method for the collection and analysis of vapor-phase
organics including carcinogenic and mutagenic substances (1-27). The
3
developed techniques were to achieve a sensitivity of ng/m . While develop-
ing these techniques, it became apparaent that a number of facets required
attention for successful completion of this concept. Figure 1 depicts
these research components which encompass the analysis of organic vapors in
ambient air using high resolution gas chromatography/mass spectrometry/com-
puter (hrgc/ms/comp).
There have been two major areas of effort. One area involves the
design and fabrication of devices while the second involves experimental
evaluation. With regard to a collection method, design criteria and the
preparation of appropriate sorbent media must be undertaken. These aspects
have been previously discussed and reported (1-11). In addition, upon
collection of organic vapors, a provision for their transfer to the instrumen-
tal method must be made. The design criteria, fabrication of an inlet
manifold and associated capillary technology for use with mass spectrometry
have also been briefly described (1-5,27). Finally, computer software must
be developed with features which allow for rapid data interpretation.
Concommitant with the design and fabrication of devices, experimental
evaluation has been conducted to varying degrees at each step of this
method (Fig. 1). Collection efficiences, breakthrough volumes and research
on displacement chromatography have been previously discussed (1-5). More
recent work has centered on the examination of in situ reactions potentially
associated with the collection device, as well as, the effects of storage
on sample integrity. As an integral part of the instrumental method of
analysis, the accuracy and reproducibility of sample recovery, and separation
and resolution of components in the ambient air sample has been briefly

investigated (1-5). The assorted mass spectrometric techniques available
for ambient air characterization includes electron impact, positive chemical
ionization, negative chemical ionization, mass analyzed ion kinetic energy
spectrometry as well as others. Virtually no research has been conducted
with the latter three.
Finally, qualitative and quantitative techniques are needed for data
reduction which expedites the overall sample analysis,
Many of the components in the two general areas outlined in Figure 1
have been examined over the past several years, however considerable effort
is still required, in particular, their evaluation and validation.
To-date a considerable amount of qualitative and quantitative data has
been accumulated utilizing the developed methods. Ambient air sampling has
been conducted involving many types of industrial atmospheres located
throughout the Continental U.S. (1-27).
In this report, we continue to provide information on experimental
evaluation and validation of the previously developed methods as well as
the acquisition of information on the composition of atmospheres asssociated
with industrial activity.

SECTION 2
CONCLUSIONS
Studies were conducted on in situ reactions potentially occurring as a
result of the presence of criteria pollutants (ozone, NO, NO,, NO ), mole-
fa A
cular halogens and olefins occurring simultaneously in the atmospheres sam-
pled. Under laboratory simulated conditions, no in situ reactions were
observed when sampling atmospheres using a Tenax GC cartridge containing
molecular chlorine or molecular bromine in the presence of criteria pol-
lutants and ethylene, propylene and 1-butene. However, traces of 2,3-di-
chlorobutanes were detected from 2-butene. Also, very small quantities of
1,2-dichlorocyclohexane was detected as a reaction between chlorine and
cyclohexene. The formation of these two halogenated hydrocarbons occurred
under high levels of molecular chlorine and olefins. The incorporation of
sodium thiosulfate into the glass fiber filter prior to a Tenax GC sampling
cartridge for removing particulates inhibited the formation of chlorinated
or brominated substances.
Development of computer software programs to assist in quantitation of
the vapor-phase organics collected from ambient air substantially increased
the efficiency of the overall technique. Two computer programs were develo-
ped, one provided the capability to sum ions representing classes of com-
pounds over the mass spectra obtained in a gas chromatograra for a sample
while the other provided the capability of determining the response (peak
height or area) for a selected ion with subsequent ratioing of the intensity
of the selected ion with respect to an internal standard to yield response
factors as well as the quantity of the individual unknown component.
A series of relative molar response factors was determined for a
number of hydrocarbons, aromatics, halogenated hydrocarbons and oxygenated
compounds. The combined use of a permeation system for synthesizing air/va-
por mixtures high resolution gas chromatography and mass spectrometry
yielded RMR data for individual selected ions of each specific compound
-------
with a reproducibility of at least +10% for replicate analysis. A statisti-
cal evaluation was conducted to compare the relative molar response factors
within replicate determinations as well as to determine the variation of
the RMR between compounds for the same selected ions. It was concluded
that in some cases, ions common to several compounds within a homologeous
series provided similar RMR values and thus an "average" RMR value could be
used to extrapolate concentrations of compounds for which authentic material
did not exist.
The collection and analysis techniques employing the Tenax GC cartridge
and high resolution gas chromatography/mass spectrometry/computer was
applied to the analysis of vapor-phase organics in ambient air for three
major geographical areas (7 sites) in order to validate the technique by
characterizing atmospheres where the composition of the industrial atmosphe-
res was partially known. A group of halogenated hydrocarbons were identified
in the atmospheres collected from the Houston, TX vicinity, Baton Rouge, LA
area and New Jersey. Many of the compounds appeared to be site-specific.
For example, some site-specific pollutants were chloroacetylene, vinyl
chloride, chloroethane, vinylidene chloride, dichlorobutene isomers, 1,1,2-
trichloroethane, bis(2-chloroisopropyl)ether, dichlorobutadiene isomers,
1,3-hexachlorodibutadiene, 1,3-dichloropropane, trichloropropene isomers,
1,1,2,2-tetrachloroethane, tetrachloropropane, hexachloroethane, perchloro-
butadiene and chlorotoluene isomers which were identified in the Plaquemine,
LA area. Other site-specific compounds were also detected in Geismar and
Baton Rouge, LA Deer Park and Pasadena, TX and Deepwater and Linden, NJ.

SECTION 3
RECOMMENDATIONS
During the course of this research program, a number of areas have
come to light which need further attention. Eleven major phases of research
should be expanded and pursued. (1) New polymeric sorbent substances
should be developed for the collection of the very polar hazardous substances
which are not retained by Tenax GC. This may involve the synthesis of
analogs which are modified polymer bases of Tenax in order to incorporate
the desired retention volume properties for organics without increasing the
overall background contribution and retention of inorganic gases and water.
(2) Potential displacement chromatography should be examined for the sorbents
Tenax GC and a new polymeric substance when it is developed under field
sampling conditions. This information is needed in order to ascertain
whether the breakthrough volumes that have been determined under ideal
(laboratory) conditions are relevant to field sampling where high pollution
may cause competition between pollutants for adsorption sites. (3) An
evaluation of the collection media for in situ reactions with particular
emphasis devoted to examination of potential artifacts under field sampling
conditions. This activity should delineate problems associated with sampling
of atmospheres containing molecular chlorine, bromine or iodine in combina-
tion with olefins, NO , SO. and ozone. Other potential in situ reactions
X M """""' -•—•-—'
on the sorbent bed should also be examined such as the ozonization of
olefins under field sampling conditions. (4) An evaluation study should be
made for drying the sorbent collection device albeit Tenax GC or a new
synthesized polymer with a dehydrating agent such as calcium sulfate (or
equivalent). Storage studies should be conducted to determine the accuracy
and reproducibility of such a technique. (5) Further research is needed in
regard to flow controls and the maintenance of a constant temperature on
the sampling device to improve quantitative collection of atmopsheric
vapors. Because the collection device is potentially subjected to variations
-------
in temperature and thus breakthrough volumes the use of a constant tempera-
ture bath for housing of the collection device should be investigated.
This may include studies on the effects of condensation on collection
efficiency and the storage of organic vapors on the sorbent medium. (6)
Research should be initiated on evaluating the accuracy of the sampling
device under field sampling conditions. This may require the use of radio-
isotopes incorporated in permeation tubes which are used to spike the
endogenous organic pollutants followed by the subsequent determination of
the accuracy of collection by measuring the radiotracer substance. (7) The
reproducibility of storing the field collected organic vapors should be
evaluated. This should include the reproducibility of storage for the
individual components in the sample and the total organic vapor profile
which was collected. (8) Substantial effort should be devoted to developing
capillary technology for the analysis of hazardous (mutagenic, carcinogenic,
toxic) substances collected from the ambient air. This should include the
investigation of suitable stationary phases coated in glass capillary
columns (SCOT and WCOT) as single pure phases as well as multiple phase
combinations. (9) Research should begin on examining alternate methods to
electron impact mass spectrometric techniques such as negation ion chemical
ionization for halogenated hydrocarbons, selective chemical ionization for
specific chemical classes, and mass analyzed ion kinetic energy (MIKE)
spectrometry. (10) Evaluation and development of new qualitative and
quantitative software techniques should be undertaken to handle large
quantities of mass spectrometric data. This development and perfection
should provide a single software package allowing for the characterization
and quantitation of mass spectral information contained in a single sample
run. Particular emphasis should be devoted to a capability which allows
for bulk data processing at low cost. (11) Efforts should begin on develop-
ing concepts for overall automation of the developed collection and analysis
methods for vapor-phase organic substances occurring in ambient air.

SECTION 4
PROGRAM OBJECTIVES
The general objective of this program was to fabricate the necessary
instrumentation to collect and evaluate urban air samples using the services
of a gas chromatograph in combination with a mass spectrometer. Preliminary
emphasis was to be placed on developing a collection system of such suf-
ficiency as to meet the sensitivity limitations of the analyzer combination.
A major emphasis of this program was the quantitated determination of urban
air organic pollutants, The specific aims of this program were: (a) to
formulate a sample collection system which would permit in the minimum the
q
analysis of pollutants in the vapor-phase present at low ng/m concentra-
tions. This included delineation of those parameters which are important
in striving for a quantitative method of analysis; (b) demonstration of any
limitations with regard to chromatographic resolution of urban air pol-
lutants; (c) demonstration of the quantitative sensitivity of the overall
collection and analysis systems for several classes of potential pollutant
candidates, and (d) the analysis of vapor-phase ambient air pollutants by
the use of gas chromatography in tandem with mass spectrometry with special
emphasis on demonstrating the overall analysis method as a quantitative
technique for atmospheric organic vapors which can be used concurrently
with qualitative characterization.

SECTION 5
STUDIES ON POTENTIAL IN SITU REACTIONS OCCURRING ON TENAX GC SORBENT
An approach to the detection, identification and quantification of
halogenated hydrocarbons in the ambient air has been previously described
and has been further studied in this program (1-27). Ambient air was
sampled using a Tenax GC cartridge technique and sample analysis employed
high resolution (glass capillary) gas chromatography/mass spectrometry/com-
puter (hrgc/ms/comp) methods. Many halogenated hydrocarbons have been
identified and quantified in ambient air from several geographical regions
throughout the Continental U.S.
In view of the potency and the broad spectrum of carcinogenic activity
for the identified halogenated hydrocarbons in experimental animals, the
detection of these compounds in the atmosphere has generated considerable
interest in their origin. Many of the studies reported in Section 7 were
initiated to determine their emission from stationary and fugitive sources
as well as their potential formation through photochemical reaction from
precursors.
In order to determine whether halogenated hydrocarbons may be present
in the atmosphere from industrial sources or as an atmospheric chemical
reaction, it was first necessary to know the extent to which it may form at
trace levels as an "artifact" of the technique employed or the sample col-
lection process. Furthermore, the experimental methods should differentiate
between homogeneous and heterogeneous reaction mechanisms.
Our primary concern has been with the use of the Tenax GC sampling
cartridge which has been extensively employed for collecting organic vapor
from ambient air for characterization and quantification purposes. Since
the Tenax GC cartridge may concentrate reactive compounds including ozone,
NO and for example molecular chlorine or bromine, the possibility for in
situ formation of artifact compounds may occur. This may occur eventhough
-------
inorganic gases do not appreciably accumulate on the sorbent (8). It was
the purpose of this study to further supplement the previously reported
observations, i.-e., the in situ formation of N-nitrosamines, as to whether
other additional in situ reactions could occur on the Tenax GC sampling
cartridge (11,14).
Since urban air often contains substantial concentrations of ozone, we
conducted a series of laboratory experiments to determine whether air
containing both NO and ozone might be more effective in converting olefins
A
plus molecular halogens than air containing only NO . Experiments were
«m
designed to delineate the transformation of olefins whether adsorbed on the
Tenax GC or occurring in low concentrations in air via homogenous atmospheric
reactions or heterogeneous reactions which might take place on the walls of
the sample inlet tube. In addition to the halogenation of olefins, we were
interested in the possibility of reactions between ozone and olefins produc-
ing polar products which also might be considered as artifacts of the
collection process.
EXPERIMENTAL
The apparatus used to determine whether air containing ozone, NO
(Matheson, Coleman, Bell), N0» (Matheson, Coleman, Bell), olefins, molecular
halogens and water might convert olefins to halogenated compounds on Tenax
GC (35/60, Applied Science, State College, PA) is depicted in Figure 2.
Nitric oxide was measured! into the stream with a rotameter and a metering
valve from a supply tank which contained ppra of NO and nitrogen (Scott .
Environmental), Ozone was generated by an ultraviolet lamp equipped with a
sliding cover for obtaining different concentrations. Concentrations of
NO, N02 and ozone were monitored with a Bendix NO analyzer (Model 5513802)
and a Bendix Ozone analyzer. Intakes for these instruments were at the
same point as the intake for the Tenax GC glass cartridge sampler (1.5 cm
i.d. x 6.0 cm bed length) through which air was drawn by a Nutech Model
221-A (Nutech Corp., Durham, NC) sampler. The sampling cartrige and the
analyzer inlet tubes were centered in the air flow pattern from the reaction
tube. Various levels of relative humidity in the air stream were produced
by changing the temperature of the humdifier bath.

-------
Permeation tubes (TFE) of molecular chlorine and bromine were prepared
and gravimetrically calibrated with a MS-5A Mettler balance after their
equilibration to a constant rate.
Prior to its use, Tenax GC was purified by Soxhlet extraction for 18
hrs with methanol and n-pentane, respectively. After drying under nitrogen
atmosphere, Tenax GC was heated to 150°C for 2 hrs in a vacuum oven (12" of
water), sized into a 35/60 range and packed into glass tubes. All sample
cartridges were preconditioned by heating to 275°C for 20 rain under a helium
®
purge for 20-30 ml/min. After cooling in precleaned Kimax culture tubes,
the containers were sealed to prevent contamination of the cartridge.
Replicate samples and blanks were analyzed by gas chromatography equip-
ped with flame ionization detection. Thermal desorption was used to transfer
vapors from the cartridge sampler to the analytical system using a specially
designed manifold (1-5). In a typical thermal desorption cycle, sampling
cartridges were placed in the desorption chamber (275°C) and helium gas was .
passed through the cartridge ("^20 ml/min) to purge the vapors into the
liquid nitrogen cooled nickel capillary trap. After desorption (4 min), the
six-port valve was rotated and the temperature on the capillary loop was
rapidly raised (>150°C/min). The carrier gas introduced the vapors onto the
capillary glc column. The 100 m glass SCOT column containing OV-101 statio-
nary phase and was programmed from 30°C to 240°C at 4°C/min.
A Varian MAT CH-7 glc/ms 620L computer system equipped with an inlet
manifold was used for analyzing Tenax GC cartridges where structural confir-
mation was required. The software programs available with this system
provides for reconstructed gas chromatograms and mass fragmentograms for
correlation between mass spectrum number and retention time. Operating
parameters for the hrgc/ms/comp system are given in Table 1. A single stage
glass jet separator interfaced the SCOT capillaries to the mass spectrometer.
RESULTS AND DISCUSSION
A series of experiments were conducted which examined the potential in
situ formation of chemical substances or their decomposition on the surface
of the solid sorbent Tenax GC. The experimental conditions chosen were
selected to allow the detection of potential in situ formation of organics

substances under typical atmospheric conditions encountered during field
sampling.
Table 2 presents the series of experiments which were conducted utilizing
different combinations of ozone, NO , NO, NO-, chlorine and ethylene. The
•A £•
volume of air stream sampled was 16 Si in all cases. In all experiments
(Expts. 1-15) with or without the presence of a glass fiber filter in front
of the Tenax cartridge, no dichloroethane was detected. In Expt. 16-18,
standard amounts of authentic dichloroethane were loaded onto cartridges to
obtain a standard curve response for the flame ionization detector. The
detection limit was vLO ng/cartridge.
Table 3 presents additional experiments on the effect of NO, N02 and
ozone on chlorination of ethylene. In these experiments, higher concentra-
tions of ozone were added to the extent that in some cases (Expt. 19 and 22)
excess ozone was present. In other experiments, high concentrations of NO,
and N02 were created to provide extreme atmospheric conditions to determine
whether it was possible to produce chlorinated ethylene. As depicted in
this table, no 1,2-dichloroethane or other products as the results of reac-
tions between these reagent gases could be detected. The detection limit
was VLO ng using a flame ionization detector.
Table 4 presents experiments employing various concentrations of standard
pollutants and a mixture of olefins. Other olefins which might be more
reactive were used to determine whether any halogenated hydrocarbons might
be formed. The olefin mixture consisted of ethylene (10 ppm), propylene
(9.92 ppm), 1-butene (12.8 ppm), cis-2-butene (7.82 ppm) and trans-2-butene
(8.40 ppm). The flow rate was 250 ml/min into the mixing chamber prior to
the reaction tube. Thus the various concentrations of olefins as indicated
in Table 4 were produced. These olefin concentrations and the relative pro-
portions remained the same for all experiments (Table 4). Molecular chlorine
was introduced from a permeation tube (Metronix Assoc. Inc.) which had been
calibrated to determine its permeation rate.
Again, no dichloroethane was detected in these experiments (Table 4).
However, 2,3-dichlorobutanes (racemic and meso forms) were detected. Their
formation also occurred in the absence of standard pollutants (Expt. 3).
Indicated in this table are the relative amounts of each product based upon

peak height response to the flame ionization detector. These results suggest
that small quantities of chlorinated substances may be produced when molecular
chlorine and 2-butenes (with or without standard pollutants) are presented
to a Tenax GC sampling cartridge.
Table 5 presents experiments concerning the effect of NO, NCL and ozone
on the chlorination of olefins (581 ppb ethylene, 577 ppb propylene, 744 ppb
1-butene, 455 ppb cis-2-butene and 488 trans-2-butene were the chamber
concentrations). Ethylene, propylene and 1-butene did not yield detectable
chlorinated hydrocarbons (detection limits VLO ng using flame ionization).
On the otherhand, significant quantities of 2,3-dichlorobutane (racemic and
meso) were detected. In the absence of ozone, NO , NO and N0« molecular
X fc
chlorine and 2-butene did react whether it was introduced immediately in
front of the Tenax GC cartridge or in the front of the flight tube to produce
dichlorobutane mixtures (Expt. 17). On the otherhand, the addition of NO to
the reaction between chlorine and 2-butene appeared to suppress the chlorina-
tion reaction (Expt. 12). In cases in which ozone was added or ozone plus
NO, NO-, low yields of chlorinated butanes were found.
Experiments 18-22, 24 and 28-31 were conducted in which the olefins
were introduced at the beginning of the flight tube and sampling was conduc-
ted using a glass fiber filter impregnated with 10% sodium thiosulfate in
front of the Tenax GC cartridge. In all of these experiments, regardless of
the concentration of ozone, NO , and NO,,, no chlorinated products were
X *•
detected. These experiments are contrasted with Expts. 23 and 27 which a
glass fiber filter was used which had not been impregnanted with sodium
thiosulfate.
The capacity of filters which have been impregnated with 10% sodium
thiosulfate was tested using an ozone concentration of 200 ppb. A volume of
400 $, of air was pulled through the filter. The filter was then placed in-
line with the ozone monitor and no ozone was detected. The filter was not
tested to its breakthrough limit since field sampling does not generally
exceed a sampling volume of 200 S, and ozone levels seldom exceed 200 ppb.
The reaction products from the reactions between NO, NOj and ozone,
chlorine and butene appear to increase by removing the glass wool plug which

was used to anchor the Tenax or when the glass fiber filter on the intake
to the Tenax cartridge was removed. The presence of the glass wool and
glass fiber filter thus appeared to decrease the amount of artifact since
seen which is in contrast to observations on the in situ reactions for the
formation of N-nitrosamines (14). These observations indicate that the
artifact reaction occur on the Tenax sorbent to a significant extent since
yield as high as 300 ng were observed.
Furthermore, an additional artifact apparently occurred as indicated
by the presence of polar compound during gas chromatography. In Table 5,
the amount of polar material formed based upon peak height is given for the
various experiments conducted. The polar material was identified subsequen-
tly by gc/ms to be propionic acid. Traces of acetone, acetic acid, acetalde-
hyde, propionaldehyde and methyl ethyl ketone were also detected. Formation
of the major polar compound was also prevented using a sodium thiosulfate
impregnated filter. New artifacts as the result of the impregnation of the
glass fiber filter with sodium thiosulfate were not observed.
Potential in situ reaction experiments have also been conducted using
ethylene and bromine. No artifacts have been observed. The detection
limit for ethylene dibromide was approximately 50 ng when using flame
ionization detection. Tables 6 and 7 present the effects of reagent gases
and molecular bromine on in situ formation of halogenated ethanes on Tenax
GC.
Table 8 gives the effects of standard pollutants, molecular bromine
and olefins on in situ formation of halogenated compounds on Tenax GC. For
the combination of reactive gases plus the olefin mixture as listed in the
Expts. 1-16, no 2,3-dibromobutane was detected.
These results suggest that the formation of 2,3-dichlorobutane to be a
rather unusual reaction since no other olefins appear to react with molecular
chlorine and bromine in the presence or absence of criteria pollutants.
The incorporation of sodium thiosulfate into the glass fiber filter may
provide a new avenue for eliminating potential in situ formation reactions
as a results of the presence of molecular halogens and/or ozone. It would
be interesting to conduct further studies in light of these new observations
as to whether the in situ formation of nitrosamines can be eliminated or

DEVELOPMENT OF METHODOLOGY FOR QUANTITATIVE ANALYSIS OF
AMBIENT AIR POLLUTANTS
As discussed earlier there are many facets (Fig. 1) in the development
of a technique for the analysis of organic vapors in ambient air by high
resolution gas chromatography/mass spectrometry/ computer (hrgc/ms/comp).
Among the experimental parameters which need evaluation in order to ascertain
whether a method can become a quantitative tool are collection efficiency
and breakthrough volumes for the sorbent medium under consideration, sample
recovery and transfer to the analytical system, and development of methods
for data reduction to obtain concentrations of individual components which
originally occurred in the sample. This section addresses aspects of the
method for quantitative analysis of ambient air pollutants by hrgc/ms/comp.
DETERMINATION AND COMPARISON OF BREAKTHROUGH VOLUMES FOR VIRGIN AND RECYCLED
TENAX GC
Introduction
During the past few years, the density of commercially available
virgin Tenax GC has decreased considerably. We addressed the possibility as
to whether the previously determined breakthrough volumes were also decreasing
with a decrease in density. In order to test this possibility, three batches
of Tenax were examined. These were: virgin, virgin solvent-extracted and
recycled sorbent.
Experimental
Virgin Tenax GC was purchased from Applied Science (State College, PA).
Also Tenax GC purchased from the same source which had been recycled more
than twenty times and was more than three years old was selected for evalua-
tion.
25
-------
Breakthrough volumes for five chemicals were determined using previously
described techniques (5,8). The elution volume for vapors was determined
on a chromatographic column at several decreasing temperatures and by the
use of linear regression analysis. Extrapolation to ambient temperatures
allowed the calculation of breakthrough volumes. The ambient temperature
selected for comparison of breakthrough volumes between the different
batches of Tenax was 21.1°C.
Virgin Tenax GC was also extracted in a Soxhlet apparatus for 18 hrs
each with methanol and n-pentane, respectively. The recycled Tenax GC (> 3
years in age) was also solvent extracted prior to use in this study. All
solvent was sized to 35/60 mesh before testing.
Results and Discussion
Comparison of breakthrough volumes for virgin, virgin-solvent extracted
and recycled Tenax GC is given in Table 9. The breakthrough volumes were
expressed in £/g and in A/cartridge volume. By comparing the three batches
of Tenax using these units of expression, changes in the breakthrough volume
from one batch to another whether it depended upon the density or surface
area could be determined. For methylene chloride, a variation as large as
14% was observed between virgin and virgin solvent-extracted. A 30% differ-
ence was observed for the breakthrough volume for n-hexane between virgin
and recycled Tenax. In general, the breakthrough volume of Tenax GC appeared
to be lower for the material which had been recycled (and had the highest
density) as compared to virgin or virgin solvent-extracted batches. The
least variation was changes observed between virgin and virgin solvent-
extracted sorbent. No changes were detected in the breakthrough volume
values between the originally purchased Tenax and the same material which
had been recycled for more than 3 years.
Recently purchased Tenax vs that which was several years old, exhibited
32% lower density.
These results indicate that the breakthrough volumes for organic
vapors on Tenax GC may decrease or differ slightly between batches. This
phenonmen complicates quantification using this sorbent and thus a dual
cartridge system should be used, i.e. two cartridges in tandem

vapors on the first and second cartridge can be determined and related to
breakthrough volume under field sampling conditions. Using this approach,
the variation in the breakthrough volumes between lots of Tenax as well as
any variation in displacement of organic vapors occurring as a competitive
adsorption-desorption process can be evaluated. A higher degree of accuracy
and reproducibility in quantitative studies using this sorbent can be expected
with this approach.
COMPARISON AND EFFECT OF TEMPERATURE (20°C and 30°C) ON PERMEATION RATES
THROUGH PLASTIC MATERIALS
Introduction
In previous reports (4,5), a permeation system was described for the
generation of air/vapor mixtures of known concentrations. The permeation
system was designed to operate at 20°C, however adsorption of organic vapors
to the glass surfaces and teflon transfer lines was experienced and thus a
study was undertaken to ascertain whether the permeation system might function
adequately at a higher temperature (e.g. 30°C).
Experimental
The design of the flow system was previously described (4,5). The
pyrex permeation tube (25 mm i.d. x 44 cm in length) was enclosed in the
jacket through which an ethanol/water mixture was circulated from a con-
stant temperature bath (Haake Model FE Circulating Bath and Thermostated
Heater). The thermostated heater was set to control the temperature at
30°C + 0.1°C.
The permeation tubes were gravimetrically calibrated on a weekly basis.
A Mettler MS-5A (microgram) balance was used.
Results and Discussion
Table 10 presents the permeation rates for a series of hydrocarbons,
halogenated hydrocarbons, aromatics, nitrogen- and oxygen-containing compounds
at 20°C and 30°C. In general, there is a 2-4 fold increase in the permeation
rate between the two temperatures; however, this increase did not interfere
with the utilization of the permeation tubes at their new permeation rates.
Furthermore, it is desirable to have the permeation rates adjusted for each

organic compound to within 1 x 10 to 5 x 10 g/min. Permeation rates in
this range are convenient for loading vapors onto Tenax GC cartridges.
Since it had been previously observed that substantial quantities of
the less volatile organic vapors (e.g. chlorobenzene) were adsorbed to the
surfaces of the permeation system, accurate delivery of vapors to the Tenax
GC cartridges was not possible. By increasing the temperature of the per-
meation system to 30°C and then subsequently maintaining the transfer lines
to the Tenax GC cartridges at > 40°C, the adsorption of the less volatile
vapors to the surface of the system were minimized.
EXAMINATION OF THE COMBINED PERFORMANCE OF THE PERMEATION SYSTEM, INLET-
MANIFOLD, AND HIGH RESOLUTION GAS-LIQUID CHROMATOGRAPHY
Introduction
In a previous report (4), modifications to a flow system for delivering
vapors from a permeation tube to Tenax cartridges for the purpose of accura-
tely loading cartridges to calibrate instruments were described. In that
study the performance of the flow system was evaluated in terms of stability
of the signal from the flame ionization detector (FID) with respect to the
criteria, of noise and drift. Noise was defined as variations in the signal
level over a period of 15 sec or less and it consisted substantially of
oscillations about the mean signal level. This noise was expressed as the
percentage of the lowest observed signal level. Part of the noise originated
in the FID electrometer but some of it also originated in the flow system.
Drift consisted of variations in signal level over a period exceeding 15
sec. It also was expressed as a percentage of the lowest observed signal
level. The noise and drift problems were believed to be due to the instabi-
lity of the pressure and flow through the air/vapor permeation device.
Modifications were made in the regulation of the flow and pressure in this
system. Noise was minimal and drift was slight except for one observation
which lasted for about 4 1/2 hrs. The behavior of the signal level when
changing from one Tenax cartridge to another was observed at pressures up to
6 in of water. No significant flucuations and signal level occurred at 4 in
of water and above. The influence of pressure on the time required for this
signal level to stabilize after insertion of permeation tubes into the
system was also observed and found to be insignificant. The signal level
32
-------
approached its final level within 20 min and sometimes required a short
additional period to completely stabilize.
It was concluded that the best method of delivering carrier gas to the
permeation tube flow system was to control the pressure in the chamber with
a low pressure regulator and control the flow rates only with the valves
which were used to split the flows. Increasing the pressure from 2-6 in of
water minimized signal fluctuations due to differences and flow resistance
of individual cartridges.
Additional studies were conducted and are described here in order to
determine the performance of the permeation system in delivering reproducible
and accurate quantities of organic vapors from permeation tubes and the
reprodubility of analysis by high resolution gas-liquid chromatography in
combination with the cartridge thermal desorption inlet-manifold.
Experimental
Standard curves were prepared for 9 compounds ranging from non-polar
to semi-polar. In each case, a minimum of triplicate analysis was performed
for each absolute weight of the organic vapor employed. Linear regression
analysis was performed on the response of the flame ionization detector vis
quantity of the organic vapor which had been delivered from the permeation
system to the Tenax GC cartridge.
The previously described thermal desorption inlet-manifold (1-5) was
used for recovering the vapors from Tenax GC cartridges (1.5 cm i.d. x 6.0
cm bed length). Thermal desorption was accomplished at 270°C. A Perkin-
Eliner 900 gas-liquid chromatograph equipped with flame ionization detection
was used. The chromatographic column was a 100 m glass SCOT coated with
OV-101 stationary phase (5). The carrier flow was ~2.5 ml/min, the hydrogen
and air flows to the fid were 35 and 225 ml/min, respectively. The thermal
desorption time was 5 min and a 2 min hold period followed by temperature
programming of the SCOT column from ambient temperature to 240°C at A°/min
was employed.
For linear regression analysis, peak heights were used of the compounds
under study and expressed vs quantity of compound loaded on the Tenax GC
cartridge.
33
-------
Results and Discussion
Figures 3-7 present the standard response curves for each of the com-
pounds studied. The variations are a reflection of the combination of:
(1) the delivery of the organic vapor from the permeation device to the
Tenax GC cartridge; (2) the trapping of the organic vapor by the Tenax GC
cartridge; (3) the efficiency of thermal desorption and transfer to the
high resolution glass capillary column; (4) the transmission of the organic
vapors through the high resolution column; (5) the linear dynamic range of
the capacity of the high resolution column coated with OV-101 phase; (6)
the specific organic vapor and (7) the linearity and reproducibility of the
flame ionization detector to the organic vapor.
The results shown in Figures 3-7 indicate that the technique of deliver-
ing non-polar and semi-polar organic vapors from permeation tubes utilizing
the previously described permeation device for synthesizing multi-component
air/ vapor mixtures can be achieved in a reproducibile and linear fashion.
The one exception was methylene chloride in which some non-linearity was
observed throughout the concentration range examined. In most cases, it
can seen that the variation was less than 5% with the exception occurring
at the higher concentrations. Statistical analysis was performed on these
data and the R values at the 95% conference level are also shown in these
figures.
The linear regression analyses for these compounds in all cases yield
a zero x-y intercept. This is important since it is conceivable that for
the quantification of many components in a given sample of ambient air will
require the use of response factors based on a "one point response curve"
since the use of standard curves of this nature will be excessively time
consuming and undesirable for quantification of many compounds. Because
the x-y intercept is zero in these cases, the feasibility of using relative
molar response (RMR) factors is greatly enhanced.

highly desirable to utilize the speed and accuracy of a computer system for
the calculation of levels of volatile organic vapors present in the original
sample. A previous report (5) described the use of the method of relative
molar response factors for quantification of organic vapors in ambient air
samples.
This section describes software programs which were fabricated in order
to allow the expedient determination of quantities of organic vapors present
in samples analyzed by hrgc/ms/comp.
Design of Computer Software Programs
The computer programs were written in BASIC and all quantification
was based on mass fragmentography. Two programs were written, one was called
"quantiate" and the second "area ratio calculation". The BASIC "quantitate"
was designed to search a specified range of spectra for maximum intensity of
standard mass and then to search for a different range of spectra for maximum
intensity and "unknown" mass followed by calculation of the ratio of their
intensities. A printout included maximum intensity for standard mass and
spectrum number of maximum intensity and then the maximum intensity for the
unknown mass and the spectrum number of maximum intensity and finally the
ratio of unknown to standard intensities. Also an option was provided for
calculating nanograms of unknown from this information using the RMR fac-
tor. The "quantitate" program executed the following mathematical rela-
tionships :
ng(unknown) = R g^ ^N1
R = ratio of unknown: standard itensities
Ml = M. Wt. standard
M2 = M, Wt. unknown
Nl = ng standard
R1 " ^unk/std
- Aunk/molesunk
' wtunk
AStd/n*8td/m' WtStd
A = area, or intensity
40
-------
The "area ratio" program was designed to calculate the area ratio of a
selected ion to one specified (or the sum of specified ions up to 8 in number)
over a selected range of mass spectra in the gas chromatogram. The program
utilized a subroutine for searching spectra stored on the fixed disk. Sub-
sequently the program printed the "sum or ion areas" which was either a
specified ion or a series of ions and "selected ion area" as well as the
area ratio and then indicated "saturated ion" if any intensity of an ion was
>32,736 (A/D converter saturation point). The program was used to sum ions
representing classes of compounds over most of the mass spectra obtained in
a gas chromatogram of the individual samples. The m/z 186 ion was used as
the "selected ion" since it is representative of the two external standards,
perfluorobenzene and perfluorotoluene and the mass spectra corresponding to
these two standards was summated. The area measurements were of prime
interest in most cases; however the use of "area ratios" was useful for
comparison between samples without the use of RMR factors since comparisons
could be made in this fashion on a relative basis (e.g. comparison of upwind
and downwind across a point source of pollution). Figure 8 depicts the area
ratio calculation.
The described computer software programs were written for a 6201 computer
on a Varian CH-7 mass spectrometer system; however, the principal concept
described here was developed as the basis for use in future analysis of
ambient air samples whereby quantitative information would be desired for
the individual components occurring in the sample.
DETERMINATION OF RELATIVE MOLAR RESPONSE FACTORS (RMR) FOR QUANTIATIVE HRGC/
MS/COMP ANALYSIS
Introduction
Described above was the development of computer software programs for
quantification of volatile organics by hrgc/ms. These software programs
were written in order to expedite the quantification of many organic vapors
in air samples.
Because the ambient air samples contain a multitude of organic compounds,
it is not feasible to generate standard curves for every single compound for
which quantitative information is desired. Instead a relative molar response
ratio concept would allow more expeditious estimation of the levels of the

components if the method proved to be relatively accurate and reproducibile.
Another problem associated with the quantification of many organic vapors
occurring in ambient air is that authentic standards are not available for
every compound identified. Thus it would be desirable to determine whether
empirical correlations could be derived for chemicals within a chemical
class in order that extrapolations could be made for substances for which
authentic material was unavailable commercially for determining the relative
molar response factor. Another objective of this study was to determine the
RMR factors for a series of compounds within a chemical class in order to
ascertain the sensitivity of the gc/ms/comp system and to assess the possibi-
lity of utilizing an average RMR to represent the chemical class and quanti-
fication.
Experimental
Table 11 presents the substances which have been selected for RMR
determinations. The chemical classes include ketones, aldehydes, alcohols,
ethers, esters, nitriles, sulfur compounds, alkanes, aromatics, halogenated
aliphatics, and halogenated aromatics.
In order to obtain RMR factors from the hrgc/ms/comp system, synthetic
air/vapor mixtures were prepared from a permeation system. Permeation tubes
were prepared for a series of compounds listed in Table 10. Six replicate
Tenax GC cartridges were simultaneously loaded with the same concentration
of 6-8 organic vapors. The general range of the absolute mass used for
determining RMR factors were 200-300 ng.
Tenax cartridges were subsequently thermally desorbed and analyzed by
hrgc/ms/comp and full mass spectra were acquired. An SE-30 glass SCOT
column 100 m in length was used throughout the study. The operating para-
meters are given in Table 12.
Using the previously described "quantitate" program, the relative molar
response factors for each selected ion of the organic compound and the
external standards (perfluorobenzene and perfluorotoluene) were calculated.
The resulting RMR factor for each replicate cartridge was then subjected to
statistical analysis.

Results and Discussion
An example of statistical data for the RMR factors of chloroform based
on m/z 83 and m/z 186 for perfluorobenzene is given in Table 13. Data of
this nature was obtained for all the ions selected for all the compounds
understudy. As indicated in Table 13, the arithmetic mean for the RMR
factor was 0.66 and the standard deviation was ±7.8%.
The RMR factors for several normal alkanes using selected mass ions are
listed in Table 14. The selection of several ions for each of the compounds
as well as for the external standard assures that quantification can be
conducted by mass fragmentography in lieu of complex mixtures being inade-
quately resolved by the high resolution gas chromatographic column. The
selection of ions and use of mass fragmentography provides additional speci-
ficity which is not available utilizing total ion current from the mass
spectrometer. Since full mass spectra are obtained during the acquisition
of data, it was possible to subsequently select an ion representative of the
compounds cracking pattern and displaying this vs time (mass chromatogram).
Since all of this data was automatically acquired during full scanning, the
subsequent calculations require simply executing the software programs for
determining the relative molar response factors according to the previously
described equation.
The RMR factors for several hydrocarbons and aromatic compounds and the
statistical deviation obtained for the RMR factors for each of the selected
ions is presented in Table 15. As indicated by this data, the deviation is
generally <±10% of the determined RMR valuei Data obtained by expanding
known quantities of the compound into an air space of a glass vessel and the
subsequent transfer of an aliquot to a Tenax GC cartridge, was less accurate
and reproducible than that obtained from the use of a permeation system..
The RMR factors and statistical deviations for chlorinated hydrocarbons
using perfluorobenzene as the internal standard is given in Table 16. For
each compound, a series of m/z ions which represent the mass cracking pat-
tern of that compound was selected for determining the RMR with respect to
several ions of the internal standard (e.g. m/z 186, 117, 167 and 155).
This data suggests that for a predominant number of cases the reproducibility
for determining RMR's is better than +10%.

Table 17 presents RMR factors and statistical deviations for chlorinated
aromatics using perfluorobenzene as the internal standard.
Table 18 likewise gives relative molar response factors and standard
deviations; however, for several oxygenated compounds using perfluorobenzene
as the internal standard. As with the halogenated hydrocarbons, the percent
deviation was less than +10% for each case.
Tables 19-22 also present RMR factors, however the values are calculated
with respect to perfluorotoluene as the internal standard using the ions m/z
236, 217, 186, 117 and 167.
This study is the beginning of a long-term study to obtain relative
molar response factors for many organic compounds. Data of this nature will
be examined to ascertain whether compounds may be selected for the determina-
tion of RMR's such that they are represented of their chemical class in
order to allow extrapolation to other homologues within a chemical class for
which RMR data is not available because of the unavailability of the authentic
compound for its determination.

SECTION 7
IDENTIFICATION AND QUANTIFICATION OF ORGANIC POLLUTANTS IN AMBIENT AIR
FROM SEVERAL GEOGRAPHICAL AREAS
INTRODUCTION
Three major geographical areas were selected for study. These included:
Plaquemine, Geismar and Baton Rouge, LA; Linden, Deepwater and Camden, NJ;
and Philadelphia, PA. The Plaquemine, Geismar and Baton Rouge, LA area was
chosen because of the high concentrations of synthetic organic chemical
producers and petroleum refining operations located along the Mississippi
River. Also reported for these three areas, has been a high incidence of
cancer (28,29). Thus, these areas would provide an excellent opportunity
for further methods development, identification of possible toxic organic
chemicals and formulation of pollution profiles.
The main thrust of this program has been to delineate the strengths and
weaknesses of the collection and analysis system for vapor phase organic
compounds utilizing the techniques of hrgc/ms/comp. This study was under-
taken to determine whether the collection and analysis techniques were
capable of analyzing for an assortment of chemical classes - oxygen, nitrogen
and sulfur-containing compounds.
For the Plaquemine, Geismar and Baton Rouge, LA area the potential
emissions and plant locations were examined (30,31) and it was decided that
essentially four sites would be studied. These areas included clusters of
chemical producers located at Scotts Bluff just north of Baton Rouge, the
downtown complex and the industrial sites near Plaquemine and Geismar which
are both down river from Baton Rouge. Table 23 presents the potential
emissions from chemical industry in Baton Rouge, LA.
The continuing principal objective for including Linden and Deepwater,
NJ in this program was to further validate the collection and analysis
method for halogenated, aromatic, oxygenated and nitrogen-containing

hydrocarbons associated with the chemical industry. Table 24 presents some
of the potential organic compounds associated with the E. I. DuPont de
Nemours Facility (Chambers Works) in Deepwater, NJ. Several halogenated
hydrocarbons as well as aromatic and oxygenated compounds were suspected to
be potentially present in ambient air. Sampling conducted in Linden, NJ at
American Cyanamid Corp. was to determine whether N-nitrosoamines were associa-
ted with their pesticides synthesis facility. On-site sampling at the
DuPont and American Cyanamid Corp. was conducted with the permission of the
two industrial companies.
The major portion of the chemical industry in the Catnden-Philadelphia
area was located in an area 3 or 4 miles north of the Commodore Barry Bridge
along both sides of the Delaware River in Chester, PA and Greenwich Township,
NJ. Table 25 presents the representative chemical industry along the Delaware
River of the Camden, NJ and Philadephia areas (32). The priority organic
vapors which were selected for detection and/or quantification, the ambient
air for the Camden-Philadelphia area is given in Table 26.
This section describes the characterization of vapor phase organics and
their quantification in ambient air for three major geographical areas
within the Continental U.S.
EXPERIMENTAL
The sampling methods and qualitative and quantitative techniques used
throughout this program are described and incorporated herein as Appendix A.
The procedure described in Appendix A essentially is a composite of the
techniques which have been developed under previous EPA contracts for the
collection of vapor phase, carcinogenic and toxic organic compounds with
their subsequent analysis by hrgc/ms/comp (1-27).
The ambient air sampling protocol for Plaquemine is shown in Table 27.
Figures 9 and 10 depict the sampling locations. A water tower off the
Bayou Road (Location 1) and a Church tower off of the Thesis Street (Location
2) were utilized for overnight sampling. Personal samplers were placed at
these two locations and the winds at that time were out of the north from
the industrial site (Fig. 9). The sampler on the church tower was in the
better position of the two samplers. On the following day (Tuesday), samp-
lers were placed at the corner of David Street and LA988 (Location 3, Fig.

9) which constituted an upwind sample and on the west side of the industrial
site (Locations 4 and 7, Fig. 10). Overnight sampling was conducted just
west at the industrial site at Location 6 and 7 (Fig. 10). According to the
meteorological data, these samplers were in an excellent downwind position
from the industrial site. Location 7 was located on private property. On
Wednesday, a different industrial area was examined. Samplers were placed
downwind on the edge of a sugarcane field off an adjourning road between LAI
and LA405 (Locations 8 and 9, Fig. 9). An upwind sample was taken on a
farm at the east side of the industrial area (Location 10). Distinct odors
from these plants were detected throughout the entire sampling period.
Overnight sampling was conducted under a shed just north of the sugarcane
field at Location 11 (Fig. 9). This sampling location representated a good
downwind position for only a portion of the sampling period since the winds
changed to the north toward the morning hours. A meterological research
incorporated weather station was used to provide a continuance readout of
wind direction, speed, humidity and temperature at the sampling site (5).
Meterological data was also obtained from the local airport. Hand-held
instrumentation was also used occassionally to check the performance of the
air MRI weather station (5).
Ambient air sampling protocol for Baton Rouge, LA is provided in Table
28. The corresponding sampling locations are presented in Figures 11 and
12. The general sampling strategy was to place at least one sampler in an
upwind position with the subsequent location of three or four samplers in an
arc downwind from the industrial sites. A key to these plants is given in
Table 29.
Table 30 presents the ambient air sampling protocol for Linden and
Deepwater, NJ. In both cases a total of three sampling periods were incorpo-
rated in the study, one of which involved overnight sampling utilizing
personal samplers. The corresponding sampling locations are given in Figures
13 and 14 for American Cyanaraid Corp. and Figures 15 and 16 for E. I. DuPont
de Nemours site.
Sampling protocols for the Camden-Philadelphia areas are given in Table
31 and the locations are provided on Figure 17.

RESULTS AND DISCUSSION
Plaquemine, Geismar, and Baton Rouge, LA and Vicinity
Qualitative Analysis--
The vapor phase organic pollutants which were identified in several
ambient air samples taken from the Plaquemine are given in Appendix B.
Table 32 lists the summary of the volatile halogenated organics in ambient
air which were identified from this sampling site. Over 30 halogenated
hydrocarbons were identified. Many of the compounds which were characterized
appeared to be site-specific to the industrial complex, particularly for
those samples which were taken at downwind locations. The probable site-
specific pollutants were: chloroacetylene, vinyl chloride, chloroethane,
vinylidene chloride, dichloropropene isomers, 1,1,2-trichloroethane, bis-(2-
chloroisopropyl)ether, tetrachlorobutadiene isomers, 1,3-hexachlorobutadiene,
1,3-dichloropropane, trichloropropene isomers, 1,1,2,2-tetrachloroethane,
tetrachloropropane, pentachloroethane, hexachloroethane, pentachlorobutadiene
and chlorotoluene isomers.
A selected number of samples (8) were thoroughly characterized for all
oganic pollutants present in the ambient air of Baton Rouge, LA. These
results are given in Appendix B. Samples were chosen for complete interpre-
tation based on the most favorable meteorological conditions during sampling
which would potentially yield the largest number of compounds and the highest
concentrations. Tables B1-B16 in Appendix B provide a detailed listing of
organic vapors which were identified in these samples.
Table 33 presents a summary of the organic vapors which were identified
in ambient air in Baton Rouge, LA. A total of 18 halogeaated hydrocarbons
and 25 oxygenated compounds were identified. The downwind positions from
various industrial sites were given by locations nos. 21, 26 and 27. In
these samples, two new compounds were identified which had not been previously
determined in ambient air samples collected and analyzed by the described
technique. These compounds were B-chlorostyrene and a chloroprene dimer.
Chloroprene had been previously identified in samples from Milby Park in
Deer Park, TX (4). Furthermore, we have detected 1,3-hexachlorobutadiene
which was also present in samples from Plaquemine, LA and the Houston, TX

area. Several ethers, alcohols, and other compounds were identified in the
sample taken at Location No. 21.
Quantitative Analysis--
Table 23 presented the potential emissions from some chemical industries
in this area. Much of the chemical industry was associated with the produc-
tion of halogenated hydrocarbons and assorted fine chemical products. The
availability of chemical emission data provided a good opportunity to apply
the collection and analysis methods which were developed over the past few
years. The ability to sample ambient air for which some compositional
information was available allowed fcr further validation of the method.
In addition to the chemical industry, an incineration facility was
located near Baton Rouge which destroys aliphatic hydrocarbons, aromatic
hydrocarbons, alcohols, viscous oils, polyglycols, tars, chlorinated alipha-
tics, chlorinated benzenes and other aromatics, waxes and rubber. The waste
materials which are treated at the Rollins Environmental facilities are of a
diverse origin.
Twenty-two halogenated hydrocarbons were quantified at 11 locations in
the Iberville Parish. In addition, the levels of benzene in ambient air
were also estimated. These results are shown in Table 34. Of particular
interest was the sample from Location No. 7 which contained the largest
total number of halogenated hydrocarbons. 1,1,1-Trichloroethane exhibited
3
the highest level (8,760 ng/m ). Furthermore, the highest concentration for
3
bis-(2-chloroisopropyl)ether (363 ng/m ) was observed at location No. 7.
Table 35 lists the concentration of four halogenated organics that were
detected on the carbon backup cartridge. The concentrations of chloroacety-
lene, vinyl chloride, chloroethane and vinylidene chloride appeared to be
elevated also in the sample taken at location No. 7 (Fig. 10).
Several chemicals were quantified in the samples taken in the Baton
Rouge, LA area and these results are summarized in Table 36. The predominant
halogenated compound was chloroform which was found at considerably higher
levels throughout all sampling periods at all locations relative to other
halogenated compounds which were quantified. Table 37 presents the minimum
halogenated hydrocarbon vapors which were quantified in the ambient air for
99

Linden and Deepwater,NJ Areas
Qualitative Analysis—
A few samples were selected for full characterization and these detailed
results are given in Appendix B. A summary of the volatile organics which
were identified in ambient air taken on American Cyanamid Co. property in
Linden, NJ is given in Table 38. As in previous sampling of other sites,
many halogenated hydrocarbons were identified; however, it was difficult to
ascertain which of these were site-specific. Several sulfur compounds were
also characterized. Many of these compounds represent the first report of
their detection in ambient air using the method of sampling and analysis
described from this laboratory. Two nitrogen compounds, acrylonitrile and
cyanobenzene, were also identified. Furthermore, many oxygenated compounds
were characterized with the predominant number represented by samples Pl/2
P2/3 and P3/4. These sampling locations (Fig. 14) were downwind positions.
A summary of the vapor phase organics which were identified in the
atmosphere taken onsite at E. I. DuPont deNemours are given in Table 39.
Again many halogenated hydrocarbons were identified and several were of par-
ticular interest since these were potential emission (Table 24). These were
vinylidene chloride (dichloroethylene isomer), 1,2-dibromoethane (ethylene
dibromide), trichloroethylene, carbon tetrachloride and tetrachloroethylene.
Two sulfur compounds were identified (2,3-benzothiophene and methylbenzyl
thiophene isomer). Several oxygenated compounds were also characterized.
Methyl methacrylate and acetone were also listed as potential priority
compounds of interest (Table 24). The most surprising results were reflected
by the number of nitrogen compounds in these samples since in Table 39 only
two compounds were reported, nitrobenzene and acrylonitrile. The sample
with the most number of chemical classes was P4/L4.
In addition to the analysis of these samples on an OV-101 SCOT column,
a number of duplicate samples were chromatographed on a Carbowax 20M capil-
lary. The results of these analyses are also given in Appendix B. One
constituent of interest whose abundance was relatively large could not be
identified. Its mass spectrum is given in Figure 18. The isotopic cluster

Figure 18. Mass spectrum of unknown (peak No. 46, Table B33) compound in ambient
air from Linden, NJ.
-------
for the parent ion suggests the presence of sulfur. As represented by one
of the samples which was chromatographed on a Carbowax 20M capillary, this
component was the major constituent.
Quantitative Analysis—
Several vapor phase organic compounds were selected for quantification
in all of the samples collected from Linden and Deepwater, NJ. The ambient
air levels for selected halogenated hydrocarbons, sulfur, oxygen and nitro-
gen-containing compounds and aromatics are given in Tables 40 and 41 for
3
Linden and Deepwater sites, respectively. In general ng/m quantities were
detected for most organics. The general conclusion that can be drawn from
these data is that the halogenated compounds measured appeared to be ubiqui-
tous and not site-specific since they occurred at relatively equivalent
levels in both upwind and downwind positions with respect to the American
Cyanamid site. The sulfur compounds and benzene were detected primarily in
downwind locations and suggest that they may be site-specific in origin.
This was also the case for the nitrogenous chemicals measured at the Deepwater
site. No appreciable levels of any of these materials were found in the
control sample (Tenax GC blank).
Camden, NJ and Philadelphia, PA Areas
Qualitative Analysis—
A detailed listing of the vapor phase organic pollutants occurring in
ambient air samples collected from Camden, NJ-Philadelphia, PA area is given
in Appendix B.
Quantitative Analysis--
Table 42 presents the estimated concentrations of several halogenated
hydrocarbons which were quantified in ambient air samples from this area.
The predominant compounds detected were methylene chloride, chloroform, 1,2-
dichloroethane, methyl chloroform, tetrachloroethylene and chlorobenzene.
These halogenated hydrocarbons are probably ubiquitous since they have been
found in many previous samples taken from other geographical areas.
GENERAL CONCLUSIONS
The results of the sampling analysis conducted for the three described
geographical areas has yielded considerable information concerning the
presence of vapor phase organic pollutants in the ambient atmosphere.

-------
Coupled with the information concerning the chemical industries usage,
storage, or production of chemicals, the Tenax GC sampling and the hrgc/ms/
cc.Tip analysis methodology has been applied and demonstrated to coborate much
of the chemical activity occurring at these industrial sites. Furthermore,
many new compounds have been identified particularly those which are sulfur-
and nitrogen-containing as well as many site-specific halogenated hydrocarbons
which have not been previously reported. Since the developed methodology
for collection and analysis of vapor phased organics has yielded information
concerning the specific chemicals occurring, the next phase of research
should pursue a more rigorous establishment of the accuracy and reproducibi-
lity of this technique for the chemical classes reported.
As more information is accumulated concerning the composition of the
atmosphere, it is becoming increasingly evident that many organic vapors may
be considered ubiquitous eventhough they may be of anthropogenic nature
while others are more site-specific and more directly associated with indus-
trial activity at specific sites within the Continental U.S.

APPENDIX A
METHOD FOR SAMPLING AND ANALYSIS OF VOLATILE ORGANIC COMPOUNDS
IN AMBIENT AIR BY GC/MS/COMP
119
-------
SAMPLING AND ANALYSIS OF VOLATILE ORGANIC COMPOUNDS IN AMBIENT AIR
1.0 Principle of Method
Volatile organic compounds are concentrated from ambient air on
Tenax GC in a short glass tube (1-3). Recovery of the volatile organics
is accomplished by thermal desorption and purging with helium into a
liquid nitrogen cooled nickel capillary trap (1,2,4) and then the vapors
are introduced into a high resolution glass gas chromatographic column
where the constituents are separated from each other (2,5), Charac-
terization and quantification of the constituents in the sample are
accomplished by mass spectrometry either by measuring the intensity of
the total ion current signal or mass fragmentography (2,6). The collec-
tion and analysis systems are shown in Figure A-l.
2-0 Range and Sensitivity
The linear range for the analysis of volatile organic compounds
depends upon two principal features. The first is a function of the
breakthrough volume of each specific compound which is trapped on the
Tenax GC sampling cartridge and the second is related to the inherent
sensitivity of the mass spectrometer for each organic (2,7). Thus, the
range and sensitivity is a direct function of each compound which is
present in the original ambient air. The linear range for the quantita-
tion on the gas chromatograph/mass spectrometer/computer (gc/ms/comp) is
generally three orders of magnitude. Table Al lists the overall theore-
tical sensitivity for some examples of volatile organics which is based
on these two principles (7).
The sensitivity of this technique for the very volatile organic
compounds (C^ to C^ alkanes) is inadequate for the purpose of this
study. Alternate methods for their collection and analysis are sug-
gested (11).
3.0 Interferences
The potential difficulties with this technique are primarily asso-
ciated with those cases where isomeric forms of a particular substance
cannot be resolved by the high resolution chromatographic column and
when the mass cracking pattern of each of the isomers are identical. An
example of such a problem is seen with the C5~alkyl aromatics of which

-------
there are 53 isomers. As the number of carbon atoms increases in the
hydrocarbons and aromatics, the number of potential isomers becomes
increasingly large and difficult to completely resolve by gas chroma-
tography and/or by their corresponding mass cracking patterns. However,
differentiation between the hydrocarbons, that is alkanes, alkenes,
aromatics, oxygenated, etc. can be accomplished.
4.0 Reproducibility
The reproducibility of this method has been determined to range
from ±10 to ±30% of the relative standard deviation for different subs-
tances when replicate sampling cartridges are examined (5). The inhe-
rent analytical errors are a function of several factors: [1] the
ability to accurately determine the breakthrough volume for each of the
identified organic compounds, [2] the accurate measurement of the am-
bient air volume sampled, [3] the percent recovery of the organic from
the sampling cartridge after a period of storage, [A] the reproduci-
bility of thermal desorption for a compound from the cartridge and its
introduction into the analytical system, [5] the accuracy of determining
the relative molar response ratios between the identified substance and
the external standard used for calibrating the analytical system, [6]
the reproducibility of transmitting the sample through the high resolu-
tion gas chromatographic column and, [7] the day-to-day reliability of
the ms/comp system (1-8).
The accuracy of analysis is generally ±30% but depends on the
chemical and physical nature of the compound (2,8).
5.0 Advantages and Disadvantages of the Method
The gas chromatograph/mass spectrometer interfaced with a glass jet
separator, is extremely sensitive and specific for the analysis of many
volatile organic compounds in ambient air. High resolution gas chroma-
tographic separation provides adequate resolution of the substances
found in ambient air for their subsequent quantification. The com-
bination of the high resolution gas chromatographic column and the
selection of specific or unique ions representing the various compounds
of interest identified in the air samples yields a relatively specific
assay method for these compounds (1-8).
125
-------
Collected samples can be stored up to one month with less than 10%
losses for most of the chemical classes (2,8). Because some of the
compounds of interest may be hazardous to man, it is extremely important
to exercise safety precautions in the preparation and disposal of liquid
and gas standards, cleaning of used glassware, etc. in the analysis of
air samples.
Since the mass spectrometer cannot be conveniently mobilized,
sampling must be carried out away from the instrument.
The efficiency of air sampling increases as the ambient air de-
creases (i-.e. , sensitivity increases) (8).
The retention of water by Tenax is low; its thermal stability is
high; and its background is negligible allowing sensitivity analysis
(1,2,5,8).
6.0 Apparatus
6.1 Sampling Cartridges
The sampling tubes are prepared by packing a ten centimeter long by
1.5 cm i.d. glass tube containing 6 cm of 35/60 mesh Tenax GC with glass
wool in the ends to provide support (2,5). Virgin Tenax (or material to
be recycled) is extracted in a Soxhlet apparatus for a minimum of 18
hours each time with acetone and hexane prior to preparation of cart-
ridge samplers (2,5). After purification of the Tenax GC sorbent and
drying in a vacuum oven at 100°C for 3 to 5 hours at 28 inches of water,
all the sorbent material is meshed to provide a 35/60 particle size
range. Cartridge samplers are then prepared and conditioned at 270°C
with helium flow at 30 ml/min for 30 min. The conditioned cartridges
are transferred to Kinoax (2.5 cm x 150 cm) culture tubes immediately
sealed using Teflon-lined caps and cooled. This procedure is performed
in order to avoid recontamination of the sorbent bed (2,5).
Cartridge samplers with longer beds of sorbent may be prepared
using a proportionally increased amount of Tenax in order to achieve a
larger breakthrough volume for compounds of interest, and thus increa-
sing the overall sensitivity of the technique (8).
6.2 Gas Chromatographic Column
A 0.35 mm i.d. x 100 m glass SCOT capillary column coated with SE-
30 stationary phase and 0.1% benzyltriphenylphosphonium chloride is used
126
-------
for effecting the resolution of the volatile organic compounds (5). The
capillary volume is conditioned for 48 hrs. at 245° at 2.25 ml/min of
helium flow.
A glass jet separator on a Varian MAT CH-7 gc/ms/comp system is
employed to interface the glass capillary column to the mass spectro-
meter. The glass jet separator is maintained at 240°C (2,5).
6.3 Inlet Manifold
An inlet manifold for thermally recovering vapors trapped on Tenax
sampling cartridges is used and is shown in Figure Al (1,2,4,5).
6.4 Gas Chromatograph
A Varian 1700 gas chromatograph is used to house the glass capil-
lary column and is interfaced to the inlet manifold (Figure Al).
6.5 Mass Spectrometry/Computer
A Varian MAT CH-7 mass spectrometer with a resolution of 2,000
equipped with a single ion monitoring capability is used in tandem with
a gas chromatograph (Figure Al). The mass spectrometer is interfaced to
a Varian 620/L computer (Figure Al).
7.0 Reagents and Materials
All reagents used are analytical reagent grade.
8.0 Procedure
8.1 Cleaning of Glassware
All glassware, sampling tubes, cartridge holders, etc. are washed
in Isoclean/water, rinsed with deionized distilled water, acetone and
air dried. Glassware is heated to 450-500°C for 2 hours to insure that
all organic material has been removed prior to its use.
8.2 Preparation of Tenax GC
Virgin Tenax GC is extracted in a Soxhlet apparatus for a minimum
of 18 hours with acetone or methanol prior to its use. The Tenax GC
sorbent is dried in a vacuum oven at 100°C for 3-5 hours and then sieved
to provide a fraction corresponding to 35/60 mesh. This fraction is
used for preparing sampling cartridges. In those cases where sampling
cartridges of Tenax GC are recycled, the sorbent is extracted in a
Soxhlet apparatus with acetone or methanol as described for the virgin
material, but the sorbent is further extracted with a non-polar solvent,
127
-------
hexane, in order to remove the relatively non-polar and non-volatile
materials which might have accumulated on the sorbent bed during previous
sampling periods.
8.3 Collection of Volatile Organics in Ambient Air
Continuous sampling of ambient air is accomplished using a Nutech
Model 221-A portable sampler (Nutech Corp., Durham, NC, see Figure Al,
Reference 2). Flow rates between 1-10 Jfc/min are available with this
sampling system. Flow rates are generally maintained at 1 £ using
critical orifices and the total flow is monitored through a calibrated
flow meter. The total flow is also registered by a dry gas meter. Con-
concomitant with these parameters the temperature is continuously recorded
with a Meterological Research, Inc. Weather Station since the breakthrough
volume is important in order to obtain quantitative data on the volatile
organics. This portable sampling unit operates on a 12 volt storage
battery and is capable of continuous operation up to a period of 24
hours. However, in most cases at the rates which are employed in the
field, the sampling period is generally 1-3 hours. This portable sampling
unit is generally utilized for obtaining "high volume" samples. Duplicate
cartridges are deployed on each sampling unit utilizing a sampling head
as shown in Figure A2.
In addition to the Nutech samplers, DuPont personnel samplers are
also used to acquire "low volumes" of ambient air as well as long-term
integrated samples (12-36 hrs). Identical Tenax GC sampling cartridges
are employed in this case, and the sampling is conducted in duplicate.
The flow rate is balanced between duplicate cartridges using critical
orifices to maintain a rate of 25-100 ml/min per cartridge.
For large sample volumes, it is important to realize that a total
volume of air may cause the elution of compounds through the sampling
tube if their breakthrough volume is exceeded. The breakthrough volumes
of some of the volatile organics are shown in Table A2 (2,4,7,8). These
breakthrough volumes have been determined by a previously described
technique (2). The breakthrough volume is defined as that point at
which 50% of a discrete sample introduced into the cartridge is lost.
Although the identity of a compound during ambient air sampling is not
known (therefore, also its breakthrough volume), the compound can still
be quantified after identification by gc/ms/comp once the breakthrough

volume has subsequently been established. Thus, the last portion of the
sampling period is selected which represents the volume of air sampled
prior to breakthrough for calculating their concentration. For cases in
which the identity of a volatile organic compound is not known until
after glc/ms, the breakthrough volume is subsequently determined.
Previous experiments have shown that the organic vapors collected
on Tenax GC sorbent are stable and can be quantitatively recovered from
the cartridge samplers up to 4 weeks after sampling when they are
tightly closed in cartridge holders and placed in a second container
that can be sealed, protected from light and stored at 0°C (1,2).
8.4 Analysis of Samples
The instrumental conditions for the analysis of volatile organics
on the sorbent Tenax GC sampling cartridge is shown in Table A3. The
thermal desorption chamber and the six port valco valve are maintained at
270° and 240°, respectively. The glass jet separator is maintained at
240°. The mass spectrometer is set to scan the mass range from 25-350.
The helium purge gas through the desorption chamber is adjusted to 15-20
ml/min. The nickel capillary trap on the inlet manifold is cooled with
liquid nitrogen. In a typical thermal desorption cycle, a sampling
cartridge is placed in the preheated desorption chamber and the helium
gas is channeled through the cartridge to purge the vapors into the
liquid nitrogen capillary trap [the inert activity of the trap has been
shown in a previous study (5)]. After the desorption has been completed,
the six-port valve is rotated and the temperature on the capillary loop
is rapidly raised (greater than 10°/min); the carrier gas then introduces
the vapors onto the high resolution gc column. The glass capillary
column is temperature programmed from ambient to 240°C at 4°C/min and
held at the upper limit for a minimum of 10 min. After all the
components have been eluted from the capillary column, the analytical
column is then cooled to ambient temperature and the next sample is
processed (2).
An example of the analysis of volatile organics in ambient air is
shown in Figure A3 and the background from a blank cartridge is shown in
Figure A4. The high resolution glass capillary column was coated with
SE-30 stationary which is capable of resolving a multitude of compounds

to allow their subsequent identification by ms/romp techniques; in this
case over 120 compounds were identified in this chromatograph.
8.4.1 Operation of the MS/CQMP System (Figure A5)
Typically the mass spectrometer is first set to operate in the
repetitive scanning mode. In this mode the magnet is automatically
scanned exponentially upward from a preset low mass to a high mass
value. Although the scan range >nay be varied depending on the particular
sample, typically the range is set from m/e ?5 to fn/e 300. The scan is
completed in approximately 1.8 seconds. At this time the instrument
automatically resets itself to the low mass position in preparation for
the next scan, and the information is accumulated by an on-line 620/L
computer and written onto magnetic tapes or the dual disk system. The
reset period requires approximately 2.0 seconds. Thus, a continuous
scan cycle of 3.8 seconds/scan is maintained and repetitively executed
throughout the chromatographic run. The results is the accumulation of
a continuous series of mass spectra throughout the chromatographic run
in sequential fashion.
Prior to running unknown samples, the system is calibrated by
introducing a standard substance, perfluorokerosene, into the instrument
and determining the time of appearance of the known standard peaks in
relation to the scanning magnetic field. The calibration curve which is
thus generated is stored in the 620/L computer memory. This calibration
serves only to calibrate the mass ion over the mass scanning range.
While the magnet is continuously scanning, the sample is injected
and automatic data acquisition is initiated. As each spectrum is acquired
by the computer, each peak which exceeds a preset threshold is recognized
and reduced to centroid time and peak intensity. This information is
stored in the computer core while the scan is in progress. In addition,
approximately 30 total ion current values and an equal number of Hall
probe signals are stored in the core of the computer as they are acquired.
During the two-second period between scans this spectral information,
along with the spectrum number, is written sequentially on disks, and
the computer is reset for the acquisition of the next spectrum.
This procedure continues until the entire gc run is completed. By
this time there are from 800-1400 spectra on the disk which are then
subsequently processed. Depending on the information required, that day

may then either be processed immediately or additional samples may be
run, stored on magnetic tape and the results examined at a later time.
The mass spectral data are processed in the following manner.
First, the original spectra are scanned and the total ion current (TIC)
information is extracted. Then the TIC intensities are plotted against
the spectrum number on the States 31 recorder. The information will
generally indicate whether the run is suitable for further processing,
since it provides some idea of the number of unknowns in the sample and
the resolution obtained using the particular gc column conditions.
The next stage of the processing involves the mass conversion of
the spectral peak times to peak masses which is done directly via the
dual disk system. The mass conversion is accomplished by use of the
calibration table obtained previously using perfluorokerosene. Normally
one set of the calibration data is sufficient for an entire day's data
processing since the characteristics of the Hall probe are such that the
variation in calibration is less than 0.2 atomic mass units/day. A
typical time required for this conversion process for 1,000 spectra is
approximately 30 min.
After the spectra are obtained in mass converted form, processing
proceeds either manually or by computer. In the manual mode, the full
spectrum of scans for the gc run is recorded on the States 31 plotter.
The TIC information available at this time is most useful for deciding
which spectra are to be analyzed. At the beginning of the runs where
peaks are very sharp nearly every spectrum must be inspected
individually to determine the identity of the component. Later in the
chromatographic run when the peaks are broader only selected scans need
to be analyzed.
Identification of resolved components is achieved by comparing the
mass cracking patterns of the unknown mass spectra to an eight major
peak index of mass spectra (9). Individual difficult unknowns are
searched by the use of the Cornell University STIRS and PBM systems.
Unknowns are also submitted to EPA MSSS system for identification. When
feasible, the identification of unknowns are confirmed by comparing the
cracking pattern and elution temperatures for two different chroma-
tographic columns (SE-30 and Carbowax SCOT capillaries) for the unknown
and authentic compounds. The relationship between the boiling point of
140
-------
the identified halogenated hydrocarbon and the elution temperature on a
non-polar column (the order of elution of constituents is predictable in
homologous series since the SE-30 SCOT capillary separates primarily on
the basis of boiling point) is carefully considered in making structure
assignments.
Mass spectral search programs are operational at the Triangle
Universities Computation Center (TUCC). RT1 maintains twice daily
service to TUCC, which is a one-quarter mile distance from the RTI
campus. Additional information about each magnetic tape containing the
mass spectra of halogenated hydrocarbons is entered directly into the
TUCC job stream using a remote job entry processing. This is normally
done at TUCC using one of the five terminals located within the Analytical
Sciences Laboratory. The control information contains selected spectrum
numbers of instructions to process entire gc runs. The computer program
systems compare simultaneously either the entire library of 25,000
compounds or some subset of this library. The complete reports showing
the best fits for each of the unknowns is produced at TUCC and printed
out at the high speed terminals located on the RTI campus of TUCC.
Thus, the processing of the mass spectral data obtained for the halogena-
ted hydrocarbons in the samples collected is processed by one of three
routes. Each consists of a different level of effort. The first level
is strictly a manual interpretation process which proves to be the most
thorough approach. The second level is executed when the interpretation
at the first level has not yielded conclusive results.
8.4.2 Quantitative Analysis
In many cases the estimation of the level of pollutants by capil-
lary gas chromatography in combination with mass spectrometry is not
feasible utilizing only the total ion current monitor (See Figure A3 for
example). Since baseline resolution between peaks is not always achieved,
we employ the techniques which have been previously developed under
contract whereby full spectra are obtained during the chromatographic
separation step and the selected ions are presented as mass fragmentograms
using computer software programs which allow the possibility of deconvolu-
ting constituents which were not resolved in the total ion current
chromatogram (6). Examples are depicted in Figures A6 and A7 which
represent an ambient air sample with a TIC profile as in Figure A3.

-------
The standard added can be added as an internal standard during
sampling, however, since the volume of air taken to produce a given
sample is accurately known, it is also possible and more practical to
use an external standard whereby the standard is introduced into the
cartridge prior to its analysis. Two standards, hexafluorobenzene and
perfluorotoluene are used for the purpose of calculating RMR's. From
previous research it has been determined that the retention times for
these two compounds are such that they elute from the glass capillary
column (SE-30) at a temperature and retention time which does not inter-
fere with the analysis of unknown compounds in ambient air samples.
Since the volume of air taken to produce a given sample is accura-
tely known and an external standard is added to the sample, then the
weight can be determined per cartridge and hence the concentration of
the unknown. The approach for quantitating ambient air pollutants
requires that the RMR is determined for each constituent of interest.
This means that when an ambient air sample is taken, the external standard
is added during the analysis at a known concentration. It is not impera-
tive at this point to know what the RMR of each of the constituents in
the sample happens to be. However, after the unknowns are identified
then the RMR can be subsequently determined and the unknown concen-
tration calculated in the original sample using the RMR. In this manner
it is possible to obtain qualitative and quantitative information on the
same sample with a minimum of effort.

16. ABSTRACT
Analytical methods and instrumentation for collecting and analyzing hazardous vapor
phase organics occurring in ambient air were developed and evaluated. The areas of
investigation included (a) the evaluation of Tenax GC sorbent for variations in the
breakthrough volumes for different lots; (b) studies on 1n situ reactions wh.lch might
occur during the .collection of organic vapors from ambient air; (c) evaluation of a
permeation system for delivering precise quantities of organic vapors for calibrating
instruments; (d) development of software programs for quantification of volatile organ-
ics using high resolution gas chromatography/mass spectrometry/computer (hrgc/ms/comp);
(e) determination of relative molar response factors (RMR) for quantitative hrgc/ms/comp
analysis; and (f) the identification and quantification of organic pollutants in ambient
air from several geographical areas within the Continental U.S.
