16. ABSTRACT
From 1979 through 1981 data were collected on selected volatile organics in the
ambient atmosphere of New Jersey and New York. Compounds measured were: benzene,
toluene, xylenes, styrene, ethylbenzene, nitrobenzene, chlorobenzene, dichloro-
benzenes, chlorotoluenes, vinyl chloride, trichloroethylene, tetrachloroethylene,
1,2-dibromoethane, 1,2-dichloroethane. 1,1-dichloroethylene, carbon tetrachloride,
chloroform, methylene chloride, meth. ethyl ketone, and methyl isobutyl ketone.
The sites selected included urban, suburban rural, and industrial areas: Newark,
Rutherford, South Amboy, Elizabeth, Camden and Batsto Village in New Jersey. Samples
were collected in two residential areas of Staten Island, a borough of New"York
City which is adjacent to a highly industrialized area of New Jersey. Samples were
also collected in the Yorkville area of Manhattan, to obtain an urban sample with
less impact from New Jersey industry. In addition, studies were carred out on the
sample trapping methodology, as well as on the correlation of the data obtained
with wind direction during sampling. Generally, the aromatic compounds, especially
benzene, toluene and p-xylene were the most common pollutants found and were
usually the most concentrated of the species determined. Levels were usually in
the low parts per billion range. .--

                             ABSTRACT

     From 1979 through 1981 the Air Pollution Research Laboratory
collected data on  a  selected group of volatile organic compounds
in the  ambient atmosphere  at several  sites in  the  states  of New
Jersey  and  New  York.  Included  were   aromatic  solvents such  as
benzene, toluene, xylenes,  styrene,  ethylbenzene and nitrobenzene;
chlorinated aromatic  compounds such  as  chlorobenzene,  dichloro-
benzenes,  and chlorotoluenes.  Several halogenated two-carbon
compounds were  determined  including  vinyl  chloride,  trichloro-
ethylene,  tetrachloroethylene, 1,2-dibromoethane, 1,2-dichlo-
roethane and  1,1-dichloroethylene.  Carbon  tetrachloride, chloro-
form  and  methylene chloride were  determined,  as well  as  methyl
ethyl ketone and  methyl isobutyl ketone.

     The  sites  selected  included  urban,  suburban  rural  and
industrial areas.  During 1979,  under  funding  by both EPA and the
New Jersey Department of Environmental Protection  sites in Newark,
Rutherford,  South Amboy, Elizabeth,  Camden  and Batsto Village were
sampled every sixth day. In  1980 sampling  continued in Rutherford
and  Batsto,   giving   an  18  month  database  on  a  suburban  site
impacted by industry  (Rutherford)  and a rural  site  in  the Pine-
lands  of  New Jersey  (Batsto).  The following  year  samples  were
collected in two residential areas of Staten Island, a borough of
New York City which is adjacent to  a highly industrialized area of
New Jersey. Samples were also  collected  in the  Yorkvil.le area of
Manhattan, to obtain an urban  sample with less  impact  from New
Jersey industry.

     In addition, studies were carried out on the sample trapping
methodology,  as  well  as on  the  correlation  of  the data obtained
with wind direction during  sampling.

     Generally,  the aromatic compounds, especially  benzene,
toluene and  p-xylene were  the  most common pollutants  found and
were  usually  the  most  concentrated  of the  species determined.
Levels were usually in the  low  parts per  billion range.

                           INTRODUCTION

     Epidemiological  studies  in  recent  years  have  shown  that
certain  localities  have above  average occurrences of  particular
diseases.   One possible explanation  for  this  is  that the  popu-
lation is  exposed  to different substances in each  local  environ-
ment.  Since  the  ambient  atmosphere  has  been   shown  to  contain
measureable  concentrations  of  volatile  chemical compounds  which
are known to be toxic, mutagenic, and possibly carcinogenic,  it is
important  to  develop a data base describing the exposure  of res-
idents to  these vapors. Data  on  the  correlation  between  health
effects  and exposure  to  organic  vapors  at  the part-per-billion
concentration is not yet available, but the epidemiology needed to
develop  such  data  cannot  be accomplished without  information  on
the concentrations currently existing in the  ambient air.
     The three-year  study  completed  in the Air  Pollution  Research
Laboratory  of  The  New Jersey Institute of  Technology has had  as
its major purpose the development  of a  long  term data  base on the
concentration of a selected group of volatile organic  compounds in
the  atmosphere  at several  locations  in  the New Jersey-New York
area. Monitoring was carried out over  a span of two years  at two
sites,  a residential neighborhood with considerable chemical
industry nearby, Rutherford, NJ, and a  relatively pristine area in
the  Pine  Barrens of  southern  New Jersey, Batsto  Village.   With
samples  collected  every sixth  day at   these  locations,  the  data
obtained in these  two  places  are among  the most extensive ever
tabulated.
     Several secondary purposes were also accomplished during the
project.    The development  and  refinement  of  the analytical method
was  important.  Improvements were  made continually  to raise  the
precision  of  the method,  to characterize the  properties of  the
sample trapping system, to  develop standardization  procedures,  to
improve  the sampling  system,  and to  develop  an overall  quality
assurance.-  protocol.  In addition,  some correlation  studies  were
carried out ho determine the relation between the concentration cf
the pollutants being analyzed and the direction  of  the wind during
the collection period.
     In summation, during  the course  of  this three year  project
411 samples were collected  and  analyzed,  an  analytical method was
refined,  a  quality assurance protocol  was developed,  and  studies
on sampling systems  and standardization  procedures were  carried
out.

                                   CONCLUSIONS

            The ambient atmosphere  at  a  variety of  sites  in New  Jersey
       and  New York  has  been monitored  tor  twenty seven organic  vapors
       down to the sub-part-per-billion level,  for  a  total of  two  and  one
       half years. Two sites,  Rutherford and  Batsto,  NJ were monitored
       for  two years, giving  the  longest continuous data base for this
       type of analysis.  Samples were also  taken  for  a  year  in  Elizabeth,
       South Amboy, Newark and Camden. A six-month sampling program  was
       carried out in Staten  Island, with some  samples  taken  in Manhattan
       for  comparison.
            The analytical method  has  been developed and refined  during
       the  course of the project.  The  sampling adsorbents used have been
       studied for their collection efficiency and for  their  desorption
       characteristics.  A quality assurance protocol was  developed.
       Sampling equipment was  built and improved  during the  project.
            In addition,  the collected data was correlated with the wind
       direction  prevailing  during  the  sampling  period.  A  review  of
       similar studies  in the  literature, and comparison  with  the  present
       findings is included.
            The results from the monitoring carried  out in  this  project
       show that  there are  a large number of  organic  vapors present in
       the  ambient  atmosphere,  especially  in  the urban areas sampled.
       Many samples  showed  two hundred  compounds. Of  these,  the known
       carcinogen, benzene,  proved to  be  ubiquitous,  although  at   low
       levels. The benzene  levels ranged  from a low average  of  0.9  ppb at
       the  Pineiand  site,  to a high  average  of  6.2  ppb  in  Elizabeth.
       Other   toxic  and/or suspected  carcinogenic  compounds  frequently
       detected were  toluene,  trichloroethylene,  and  tetrachloroethylene.
            The differences  in overall  contamination  of the  atmosphere by
       these  compounds  between the  urban  sites and the rural Batsto site
       is   evident,  with  many  fewer  compounds,  at  much lower   levels,
       detected.
            The monitoring of these compounds  over a  substantial  period
       of  time gener?t-fts  important  data  for future studies on the  trans-
       port of pollutants, on the  epidemiological  impact of the  organic
       fraction of air  pollution, and on  the longer range trends in these
       levels  brought about by changes  in industrial, domestic  and  trans-
       portation  patterns  in the country.

                                      RECOMMENDATIONS

                 This  work  indicates  a  number  of directions  for  future
            research. The gathering of information on health statistics in the
            areas tested and  the  correlation  of  these data  with  air pollution
            data  is  certainly a  worthwhile  enterprise,   if  sufficient  air
            monitoring data  is available.  Since this report covers  a limited
            selection of sites, and  a  relatively short  period  of time for the
            assessment of chronic health effects, it may be necessary to await
            further  data before implementing this suggestion.   Further moni-
            toring  is certainly  valuable  to extend the  time  frame  of  the
            database,  and  an extension  of  the  area  covered would also  be
            useful.  A great deal of further correlation between meteorological
            and  the pollution data presented  here is  warranted,  since  the
            correlations done  herein are only preliminary in nature.
                 During the performance of the study on adsorbents for collec-
            tion of  organic vapors from the atmosphere,  it was fourd that much
:            of  the   literature  on  the  subject was  difficult  to  use  fully  as
            different  information is  presented  in  each  and  important para-
            meters are not reported in all. The authors, therefore, feel that,
:            in order to make  adsorbent test data most useful to all workers, a
            certain  minimal  amount of  information  should  be  included  in all
:            future  publications on  this   subject.   It  appears  that several
            standard experimental  techniques  and conversion methods should  be
            adopted  for  obtaining values  of  breakthrough volumes  of volatile
1            organic  vapors  on  adsorbents.    While  the  best way  to determine
.            standard procedures would  be  through  a study  by,  or  including
j            comments from all the investigators  in this field, some temporary
            suggestions are made.
I                 Breakthrough  and retention  volume studies  using  actual  GC
i            columns  or  adsorbent columns longer  than the   actual  sampling
*            cartridges utilized in the field, should use the conversion method
!            of Butler and Burke. (1) The adsorbate sample size should optimally
j            be  in  the G.I to  50  microgram range with the  larger  samples re-
I            quiring  tests on  larger  diameter cartridges ard adsorbent quanti-
            ties.    Correlation  coefficients for  plots of   breakthrough  or
            retention  volume  versus temperature should be reported and  the
            temperature  range  over  which  the  studies  are performed  should
            approach or equal,  as  nearly as  possible,  that of  the  sample
            collection in field use.  It is also recommended that some experi-
            ments be performed to determine  if  unexpected  early breakthrough
            occurs at  lower  temperatures  (near  field sampling  conditions)  due
            to lower rates of  adsorption i.e. kinetic effects.

          SAMPLE SITE SELECTION

               Locations for the sampling were  decided in consultation with
          personnel  of   both   the  United  States   Environmental  Protection
          Agency  (USEPA)  and  the  New  Jersey  Department  of  Environmental
          Protection  (NJDEP).    Since a  project  involving  similar sample
          collection  and  analysis  was being  carried out  at  other  sites
          simultaneously for the NJDEP, data from all the sites was treated
          together and  is  reported here. Table I  lists  the  sites  and  the
          span of time over which they were  regularly  sampled.

               Rutherford was  first  brought to the attention  of  the NJDEP
          because of  what  seemed to  be  an  unusual  concentration  of cancer
          cases,  especially  children's  leukemia,  in  the  area  around
          Pierrepont  School, a local grammar school.   Since  some  sampling
          had been done  in  1978,  it was decided  that continued sampling at
          that  location  would  be valuable.  Rutherford has  a  rather unique
          combination  of  large  chemical  industries  surrounding  long-
          established,  quiet, tree-lined  residential  neighborhoods,  in
          addition, local residents were eager  to cooperate in  establishing
-,         secure  and  accessible  sampling  locations  and helping  with  the
          servicing  of   the  sampling  sites when  necessary.   Samples  were
          collected at ground  level  in  the  rear yard  of  a private  house on
!;         Pierrepont  Ave.,  within  a  block  of  the  school,  during  1979.  In
'!         1980  the  site was moved  to  a  similar  location  just across  the
 I         street.
•|              Batsto Village  was  selected  as  it  is  in an  area  which is
          little  impacted  by either  industrial emissions  or  by automobile
          traffic.  In  this  area,  also,  the cooperation  of local residents
          was helpful.  This restored colonial  village is located in a state

-------
forest preserve and is about as  isolated an  area  as  exists  in the
state of  New Jersey.  This  site and  Rutherford  were  sampled  for
approximately two continuous years. The samples were  taken  from a
second story window  in the cawmill building during  1979, and the
site was  moved  to the yard  of  a private  residence  approximately
one mile from the first location, in 1980.
     A shorter study of six months duration was carried out  at two
sites in  Staten  Island,  the communities of  Travis,  and  Mariner's
Harbor,  and  in Manhattan  in the  Yorkville  section.  These  were
selected  to  see  if  sufficient differences could  be  determined  in
the pattern and concentration of the pollutants to show the  impact
of the New  Jersey industrial areas bordering  the Arthur  Kill,  on
the residential areas  of Staten  Island. The  samples  were  taken  in
the yard  of  a  private house near the corner of Victory  Blvd.  and
Roswell Ave. in Travis and  on the grounds  of St.  Michael's  Church
in Mariner's  Harbor.    Six  additional samples  were  taken  on  the
grounds  of  the  Consolidated  Edison  generating  plant  near  the
Travis site  in September. The Manhattan site was  chosen  to  give a
basis of  comparison,  since  it  is  further  north, and  out  of  the
prevailing wind stream from the  industrial areas  in  question. The
locations of  all  the  sites sampled during  the  project  are  dis-
played on the map  in  Figure  1, and  more  detailed  maps  of  the
sampling sites are in Appendix I.
     The  other  sites  reported  here  which were  sampled  for  the
NJDEP included densely populated urban areas in Newark and Camden,
a site in  Elizabeth  which  was subjected to  both  heavy automobile
traffic and  to petrochemical  industry, and a site at the southern
end of the industrial belt of the state,  in South Amboy.

SELECTION OF COMPOUNDS FOR ANALYSIS

     The  list of  compounds  targeted for  quantitative  analysis
changed several  times during the project. The initial  list  con-
sisted  of  21  compounds,  including  several  one and  two  carbon
halogenated  compounds,  benzene,  and  a group  of  substituted  ben-
zenes. Two ketones were also included. The compounds were selected
on the basis of  their toxicity,  their volatility, and their wide-
spread use  in  industry.  Over the course of  the project  some  com-
pounds were droppad from the list because they so seldom detected,.
and  others  because  of analytical  problems.  Chloroprene  data  re-
ported during the first year has recently been found to be in\slid
due  to an error  in the  reagent  used for  calibration. After  many
samples had been analyzed by  GC/MS,  a group of six  compounds  were
added because they were  seen  in  samples and  were  well resolved  in
the  chromatogram.  In the  third year  of  the  project,   two  more
compounds were added  as  there was a specific  request  for data  on
these by the granting agency. Table II gives the list of compounds
and notes the general time that these were being determined.

         SAMPLING METHODOLOGY

              Samples were generally  collected  every sixth  day in order  to
         obtain a near-weekly sample  and to distribute the samples over all
         the  days  of  the week.  Samples  were taken  using  the apparatus
         diagraisned  in  Figure  2.  The  pumps,  Model AS1S2 or AS3SS, supplied
         by Spectrex Corp. were  powered  by rechargeable 6V batteries, when
         line  power was  not  available,  and  by 6V  DC  power  supplies when
         line current  was available.  Flows were  controlled  by varying the
         pump  speed,  and by  inlet  restricting valves  on  the pumps. Flows
         were monitored  by calibrated rotameters,  and checked against soap
         film flow meters and wet test meters at regular intervals.
)          SAMPLE COLLECTION
               Samples  are collected  over  a  twenty  four  hour  period, by
         drawing  the air to be analyzed  through  the  traps at a flow of 10

to 15 ral/min.  Each  pump can draw air through two  sampling  lines,
allowing for the collection of replicate samples cr for the  use of
two types of traps  for  improved  retention.   Usually,  a Tenax trap
is used  for  trapping the majority of the sample compounds,  as it
has been shown to readily absorb and release these materials,(2,3)
Spherocarb is used to trap the most volatile materials, especially
vinyl chloride, which breaks through a Tenax trap after only a few
liters of air  have  been collected.  The  efficiency  of  Tenax  porous
polymer  for  collection of  trace organic vapors, the  recovery of
these vapors and the breakthrough characteristics of the traps are
discussed in  a subsequent  section  of  this  report.  The  flows in
each  channel  of  the pumping system  are monitored by calibrated
rotameters,  and adjusted with needle valves.
     To  prevent  particulate  matter  from  being  drawn  into  the
traps,  a glass fiber  filter  is  placed before each  trap.    This
filter  is  impregnated  with sodium thiosulfate  to decompose  any
ozone which is present,  thus  avoiding the oxidation of the  Tenax,
and  minimizing the formation  of  artifacts.  ThiosulfTte  coated
filters  have  been tested for this  purpose(4)  and have  proven to
reduce the ozone interference without removing organic vapors.

PREPARATION OF TENAX TRAPS

     The 60/80 mesh Tenax  used  in the  sampla collection traps is
exhaustively extracted  in  order to remove  any  volatile fractions
remaining in  the  polymer.   Sixteen hour  Soxhlet  extractions with
acetone, cyclohexane and methanol,  consecutively,  are followed by
vacuum drying  at  120°  C.   This  treatment removes noticeable quan-
tities of viscous liquid material  from  the  Tenax.   The sorbent is
packed into traps fabricated  of  1/4 in. (0.64  cm)  stainless steel
tubing fitted  with  compression  connectors at each  end for attach-
ment  to  the  sampling and desorption equipment.  The  traps  are 15
cm.  in   length  and  have  an internal diameter  of  0.53  cm.   The
packing  is  retained  in the  trap with  plugs  of  silanized  glass
wool, and each contains  0.4 grams of Tenax.
     After  packing, the traps  are attached  to  a  manifold  and
heated  to  300°,  with   a  purge  of  nitrogen  flowing at  30  ml/min
through  each  trap.   This  initial  conditioning requires  approx-
imately  3 days to  remove  the extraction solvents  completely, but
subsequent reconditioning  after  use is  complete  in  8  hours.   Com-
pleteness of conditioning is assured by desorbinq a trap from each
manifold batch and  analyzing  the effluent in the same manner as a
sample.   After conditioning, the  traps are sealed with caps at-
tached to the  compression  fittings  and  stored  in individual glass
culture  tubes with  Teflon lined  screw caps.   Glass wool packing is
used  to  cushion each trap.  The culture tubes  and  glass wool are
baked to 150   before use  to  remove adsorbed organics which might
contaminate the traps,  and  the  screw caps are  boiled  in distilled
water  to eliminate the  toluene contamination  which  arose  from
them.
     Storage tests  showed  little contamination  after  room temper-
ature storage  of  up to three weeks. Some benzene  and toluene was
usually  apparant in  the blanks,  but only at  levels less than 1% of

-------
the  quantity usually  found in  the atmosphere.    After  use  for
collection and desorption of a  sample,  a trap is reconditioned for
further use.   The  Tenax shows  no signs of reduced  trapping capa-
city with  use,  but  after  20-30 cycles  the  compression  fittings
wear and begin to  leak.  At  that point  the traps  are emptied, the
Tenax  is sieved  to recover  the original mesh  size, and  is again
subjected to the solvent extraction process  to  remove any  residual
sample material  or polymer  breakdown products  which have  accum-
ulated.  The Tenax is then  repacked into new  traps.   The  devel-
opment of  channels in  the  packing is  prevented  by this  regular
repacking of the traps.

PREPARATION OF SPHEROCARB TRAPS

     Spherocarb traps  are prepared  from the  same tubing  and fit-
tings  as the Tenax traps.  Since this packing is more dense, 0.40
gram occupies  only approximately one inch  of  the  trap's  length.
This provides  a sufficient  trapping length  since   Spherocarb  is
much more retentive of  sample  gases. The packing  is retained with
quartz wool,  rather than glass,  as it was  found  that the glass
wool became friable  after  being  subjected  to  the higher  temp-
eratures  used  for Spherocarb  desorption  and  conditioning.  The
traps  are   initially  cleaned  by  subjecting  them  to a purge  of
distilled water  steam for  a period of  -several  hours. After this,
and  after each  use,  the traps  are purged with nitrogen at  400  C
for  three  hours or  more.   Traps  are sealed and  stored  in glass
culture tubes in the same manner as the Tenax.

SAMPLE DESORPTION

     Many of the previously  published methods  for  thermal desorp-
tion of  adsorbent  traps allow  only  a  single analysis  to be per-
formed on each sample.  However, it is  desirable to be able to run
more than  one analysis  of  a  particular sample,  in order  to de-
termine the  precision  of the method, to analyze  samples which are
spiked with  a  known mixture for positive peak  assignments, or to
run  samples on the GC/MS for qualitative confirmation and  analysis
of  co-eluting  species.   A  desorption  system  has  therefore been
developed which permits taking  several  aliquots  from each sample.
This systcn:,  diagrammed in  Figure 3,   consists  of   a small oven,
fabricated  in  our  machine  shop from a cylinder  of aluminum and
heated with two 400 watt cartridge heaters.  This oven fits closely
around the  tra^s.  A  1 liter dewar flask filled with methanol and
chilled to -60  C with a refrigerated probe  serves as a  cold bath.
A 10 ml stainless steel gas cylinder fitted  with a stainless steel
bellows valve,  and an  accurate gaugo  for  measuring the  pressure
complete the system.   The  sample  holding  cylinder  is  cleaned by
polishing the  interior with a  water  slurry of  carborundum grit,
rinsing with acetone and methylene  chloride,  and  treatment with
hexamethyldi?ilazane.  The  silanizing  agent  is  removed  with meth-
anol,  and   the  cylinders are  heated to  200°  C,   under  vaccuum,
before use. The technique of preparing  silanized cylinders was not
developed  until after the  sample  analyses reported  here  were

                                  10

-------
completed,  and  the  loss  of  some compounds,  especially  carbon
tetrachloride on the untreated steel surface accounts for the fact
that the  levels of carbon  tetrachloride  found in this  study are
lower than expected.
     The  sample trap,  connected between  the nitrogen  inlet line
and the  inlet  of the 10 ml  sample container, is placed  into the
oven. The sample cylinder  has been  previously  flushed  with ni-
trogen  and evacuated  to below  Imrn  pressure.    The cylinder  is
placed  in the  cold  bath and  the  bellows valve  is  opened.   The
adsorbed  sample is  allowed  to distill under  reduced  pressure into
the  chilled cylinder  for  30  minutes.    Then the nitrogen inlet
valve is  opened and any remaining sample is  purged  into the cyl-
inder with  sufficient gas to  bring  the  final  pressure  to 60 PSIA.
The bellows valve is closed  and  the cylinder assembly  is trans-
ferred to a small heating mantle where it is warmed to 120  before
injection into  the  gas  chromatograph.   There is  adequate pressure
in the cylinder to allow the  injection of at least three samples.

CHROMATOGRAPHIC ANALYSIS

     The  analysis is done on  a Varian 3700 gas chromatograph.  The
injection system  was replaced with  a  manifold which  consists of a
gas sampling  valve  having a  2 ml  volume sample loop,  a pressure
gauge,  and  a  vacuum  line  to evacuate the  sample  loop  prior  lo
filling  to  a  measured  pressure with sample.   The gas  sampling
valve is  held  at  120° and all  the exposed  lines,  through which
sample or standard mixture  pass, are  heated  with  flexible tape to
60°. The  column is connected directly to the gas  sampling valve
using a graphite ferrule. The inlet system is shown in Figure 4.
     Several columns have been used for the  separation.  A support
coated open tubular (SCOT) coated with SP2100 was initially chosen
to  provide  the  largest sample capacity.  When it was  determined
that the  column was not loaded to capacity,  a wall  coated column
(WCOT)  was  substituted.   Finally,  in  order  to achieve the highest
possible  resolution,  a fused  silica  SP2100  column,  50  meters  in
length was  installed.   This column has given superior separations
and made  it possible to reduce  the number  of connections  in the
sample stream,  by attaching the head of the column directly to the
sampling  valve.  Samples are  run with helium carrier gas at a flow
of 1.0 ml/min.
     Since  the  2 ml sample volume is large for a capillary column,
the organic fraction  is focused into a sharp plug at  the head of
the  column by  starting  the  temperature program  at  -90 .   The
temperature then rises to -4  in 1 minute, holds for 1 minute, and
ramps at  3   per minute to 90  .  The  ramp then changes  to 7  per
minute up to 140 .  The entire run takes 42 minutes.   An alternate
program,  suitable for  use  on a GC which  does not  have subarabient
temperature programming  capability, involves trapping  the sample
in  a loop  of  fused  silica  tubing cooled  with  liquid  nitrogen
before  the  column,  removing^ the cold  trap, and prograraming the
column from 40  to 140  at 3  per minute.
      At  the  end of the column, nitrogen make-up gas  is added to
the sample  at  the rate  of  30  ml/min to prevent peak broadening in

PREPARATION* OF  STANDARD GAS MIXTURE

     Gaseous standards have been prepared which contain
approximately 5 parts  per  million of each of  the  compounds being
determined.   A liquid mixture  is  gravimetrically prepared  con-
taining  each target  compound.    Two  tenths  of  a  milliliter  is
injected  through  a  septum into  an  evacuated  13  liter stainless
steel high  pressure  gas cylinder.  The fittina  behind  the septum
is warmed  to insure rapid evaporation of the mixture.   The  cyl-
inder  is then  pressurized to  1000  PSI  with  pure  helium.   The
cylinder is kept warm and allowed to equilibrate for two days, and
the mixture  is  then  analyzed  for benzene  against an NBS traceable
benzene standard mixture, supplied by Matheson Gas Co.  The deter-
mined concentration of  benzene  in the  cylinder and  the known  mole
fractions of  the  other compounds in  the  original  concentrate en-
ables  the  calculation of  the  other  concentrations.   The concen-
trations of  the compounds  in  the gas mixture are stable,  and  show
good reproducibility if  the  cylinder  is  kept heated to 60 .  When
standard  is  drawn  from  a  room temperature  cylinder,  the  less
volatile  compounds,   especially  nitrobenzene  and  the  dichloro-
benzenes  show reduced concentrations, indicating  some adsorption
of these  on the cylinder walls.  These  losses may be  as high as
50%  if heating is  neglected.   Some  compounds,  notably  ketones,
which  have  been tested  showed  a tendency  to  decline  in concen-
tration  over  a  period  of several weeks,  probably due to reactions
on the  cylinder walls.  Therefore,  it is necessary  to check the
stability of each compound added  to the mixture.
     It was  found that  there were problems associated with the use
of the  vapor phase standard.  It is  difficult to make reproducible
injections  of  the  standard for some of the  compounds.  Passage of
the  vapor  through tubing  has  the effect of removing  some of the
compounds  from  the  stream. In  addition  there  may  be  problems of
changing concentrations  due  to  diffusion effects which take place
when a  mixture  of gases flows  down  a tube.  Therefore a new system
of quantitative calibration was developed.
     Relative   response  factors  axe  developed  £OE  each  tcttyet
compound  on the  FID detector  by the following  method.  Standard
mixtures  are gravimetrically prepared from  reagent grade liquids
diluted  in  phenyl  ether  solvent.  Compounds  which are  not  com-
pletely  separated in  the chromatogram  are  prepared  in  separate
mixtures,  to avoid  integration  errors.  Injections  of 0.05 micro-
liter of  the liquid  standards  onto  the GC column are made and the
response  ratios of  the target  compounds,  normalized  to benzene
with a  response of 1.0,  are  calculated.  These  are determined from
the  area generated  from each  compound,  relative  to  the benzene
area. The gas phase benzene standard is run daily on the  chromato-
graph  to  generate  a  benzene  calibration  factor.  Each  response
ratio  is multiplied  by this daily  factor  to give a  calibration


                                 Ik

factor  for  each compound.  The calculations  are  outlined  in  the
following equations:

The average  relative  response factors,  with  their  standard devi-
ations are shown in Table III.

CALIBRATION OF THE CHROMATOGRAPH

     Before  analysis  of Tenax samples,  a 10 ppm  gaseous benzene
standard  is  run.  This  is  within  an  order  of  magnitude  of the
concentration of the desorbed  samples,  and well  within the linear
range  of  the FID.  The  calibration factor  is  compared  with the
running average  and entered  on  the control  chart, a  portion  of
which  is  shown  in Figure  5.   If the value  is  out  of control
limits, the  run  is  repeated,  after the flows of air  and hydrogen
to  the detector  have  been  checked, and  readjusted  if necessary.
The running  average is  updated, and the benzene  factor is entered
into  the  computing  integrator as  a factor to multiply each peak
area.  The  relative  response factors for  the  individual compounds
are permanently  stored in the computer analysis file.   The mixed
gas standard is  used to  update retention  times,  The quantities  of
the halogenated  compounds  found  by this method  are used to cali-
brate  the BCD.
     The quantitative  vinyl  chloride  standard,  supplied  by Scott
Specialty Gases,  is run on  the  GC before Spherocarb  samples are
run,  to deternine both  the retention  time  and the  quantitative
response.

TRAPPING AND RECOVERY EFFICIENCY

     The overall  efficiency of the system for  collection  of the
sample, recovery,  and  analysis  has been tested  in  a  series  of
experiments.  A  stream of nitrogen  is passed  through a Tenax trap
at  the usual  air  sampling  rate  of  10  to  15  ml/rain,  and  2  ml
portions of  standard gas mixture  are injected into  the stream  at
intervals.   When an amount  of  sample  similar  to that collected  in
an  air  sample has  been loaded, the trap  is  removed,  stored for a
length of time comparable to  storage  of actual samples, and anal-

yzed as  a sample.   The results  of this  study  is summarized  in
Table IV.  While this method does not distinguish between trapping
efficiency and  desorption  efficiency,  some  mechanisms  of  sample
loss can  be proposed.   Carbon tetrachloride,  1,1,2,2-tetrachloro-
ethane,  1,1-dichloroethylene  do  not  appear  to  be  efficiently
trapped by Tenax, and there is some  evidence  that there is loss  of
these compounds as they pass  through the  stainless  steel delivery
lines.  The sample  holding  cylinders also appear to cause loss  of
these compounds. The  recovery of  nitrobenzene is also low  due  to
the difficulty of removing  it completely from the Tenax.
      The completeness of desorption obtained  using  the  apparatus
described, has been verified by putting traps loaded with standard
through  the desorption process twice  in  succession.   The  second
drsorption showed a maximum  of only 9% of the amount  of any com-
pound  found   in  the  first  desorption,  for   six  replicate  traps
loaded  with  quantities comparable  to   those  found  in  ambient
samples.

IDENTIFICATION OF PEAKS IN  THE CHROMATOGRAM

     A spiking method  was  developed to aid  in  the  identification
of  peaks  in  the  complex   chromatograms   obtained  from  the  air
samples.   After the  sample  concentrate  is  analyzed, the  sample
remaining in the 10 ml cylinder is spiked with a small quantity of
the standard mixture  and is  then  rechromatographed.   The increase
in  peak  height  or the  appearance of new  peaks  locates  the com-
pounds of  interest.  Spiked  samples  are run  at  regular intervals,
especially when the sampling location is changed.  Within an area,
compound  peaks vary  in size from day to  day/but  the  general pat-
tern of  substances present changes  very little.  Two  typical chro-
matograms of  air  samples done on the glass and  fused  silica col-
umns are shown in Figure 6.
     The  high  resolution  of  the  chromatography makes  co-eluting
peaks uncommon, but when they do  occur,  the  method  cannot distin-
guish them.   Mass  spectrometry is the most viable answer to that
problem,  and  GC/MS  analysis  is  performed on samples at regular
intervals.  The GC and GC/MS have shown very  good agreement on the
qualitative analysis/  and  no  species  were observed  to  interfere
with the target compounds in field samples.

from the GC system  are performed  on  a  Varian MAT  44 quadrapole
mass  spectrometer.    Approximately  5%  of  the  total  number  of
samples  were  analyzed   by GC/MS.  This analysis provided  quali-
tative verification of  the target pollutants  and identified other
volatile  organic species which were present  in  the  atmosphere  of
the  sampling  sites  at levels  above 0.1  ppb.  GC/MS  analysis  of
Tenax-adsorbed samples  is  capable  of  verification of all  target
compounds, including  vinyl  chloride.   Mass  spectral  analysis  of
Spherocarb samples  qualitatively identifies vinyl  chloride,

     GC/MS  analysis is  accomplished  by  use  of  an  identical  GC
column to that used in the routine GC analysis and the temperature
program  is similar,  except  for  the  subambient  section  of  the
program.   The  sample  is  focused by use of  a  liquid  nitrogen  cold
trap.
     The sample cylinder containing the vapor  concentrate from the
desorbed sample is  ready  for  GC/MS  analysis after  one  aliquot  has
been withdrawn for  GC  analysis.  At  this point the 10  ml cylinder
contains approximately 20 psig  sample pressure. This  is admitted
to an  evacuated  3  ml loop  through  a  gas sampling valve and  con-
nection  line,  heated  to  100  C.  The  sample is  injected onto  the
column and is cryogenically focused in a 10 cm length of 0.2 mm ID
fused silica tubing held at -195° with liquid  nitrogen.
     The sample  is retained  in  the liquid nitrogen trap  for  10
minutes  while the  relatively  large  quantities  of  nitrogen  and
oxygen are flushed through the column.  The cryoloop is then heated
to room  temperature to allow the sample  plug  to continue  through
the column. The column temperature  program  is  then initiated.  The
column is held at  32°  for six minutes  and the temperature  is  then
raised at  4° per minute  to  a  final  temperature of  145  .  The final
temperature is held for 10 minutes,  before ending the analysis.
     The  mass  spectral   analysis  does  not  clearly  distinguish
between  isomers  such  as  o-and p-dichlorobenzene  and  o-  and
p-chlorotoluene.  These  species  are,   however,  separated  by  the
GC/MS  in the  fused silica  capillary  column and,  therefore,  when
both of  the isomers are  present  in a  sample, two distinct peaks
with the same mass spectral characteristics are observed.  Highly
volatile species such  as vinyl  chloride  or acryionitrile  are  not
as easily  r3solved by  the GC/MS as  by  the  GC used  for  routine
analyses, since the GC/MS does not have the subambient temperature
program which allows better resolution of the  lighter compounds. A
larger number of species,  including C^  to C.,  hydrocarbons, there-
fore elute  in a short  period  of  time at the very beginning of the
GC/MS chromatogram. One somewhat saving aspect is that the chloro-
carbons  and acrylonitrile have  distinct  chlorine tags  or parent
peaks  separated  from  the hydrocarbon  background,  which  can  be
observed  if higher  than  trace  levels are present.  Analysis  of
acrylonitrile in the standard indicates that concentrations of 0.5
to 1.0 ppb  and higher  in  a  sample  should  be readily  observable on
the GC/MS.  This leads  to  the  conclusion that  acrylonitrile is  not
present above these levels in the majority of  the samples analyzed
by GC/MS in this study,  or  that  it  is  not well retained by Tenax.
Acrylonitrile was  observed in samples  taken  at the  Travis site,
but the  levels appeared to be just at the detection limit.
      Vinyl chloride and  vinylidene chloride,  which  also elute in
this area  of  the  chromatogram,  have the  unique  mass spectral  tag
of a  chlorine attached  to a hydrocarbon  chain, and  can  be  more
readily  observed  when  present  in low  quantities.  Vinylidene
chloride was observed  frequently  in the mass  spectral  analysis as
it is  reported in  the  routine  GC  analyses.  It appears that  the
levels  observed  on  the   mass spectral analysis were lower  than
                                21

those reported  in some  of  the GC  analyses.  Perhaps  a  coeluting
peak complicates the GC analysis of this compound.
      All other  volatile organic  compounds routinely  observed  by
GC were also regularly seen on the GC/MS analyses. These compounds
appear  to  elute without  interferences  in  the  capillary  GC/MS
analysis. Tables V, VI and VII list the target compounds and other
compounds observed in the GC/MS analysis, grouped by the frequency
with which they appear in samples.
     A large number of the compounds  trapped  from the  samples are
unsubstituted  alkanes  and alkenes,  branched  and  straight  chain,
including  hydrocarbons   from  butanes through  dodecanes. For  ex-
ample, Table  VIII lists the  Cg hydrocarbons which  are  routinely
observed in the GC/MS analysis of Tenax samples.

BREAKTHROUGH STUDY

     A  separate  study  was  carried  out  to  assess the  trapping
efficiency of Tenax toward some of the pollutants measured in this
project.  An attempt  was  made to  challenge  the  adsorbent  with
volumes of  sample and diluent comparable  to those found in actual
samples,  and  to  develop data on  the occurrance  of breakthrough
under differing conditions of flow, temperature and concentration.

Liquid Injection Experiments

     The  studies were done with  a Varian  3700  gas chromatograph
equipped  with  a  flame   ionization  detector and  temperature  pro-
gramming module.   The  trap under study was mounted  as the column
in  the  GC  oven. Nitrogen was used  as  the  carrier gas  and  was
consistently maintained  at  a known  flow  rate (30  +0.2 ml/min).
T'.ie  hydrogen  and air flows to  the  flame  ionization detector were
maintained  at  30 ml/min and  300  ml/min respectively.   The gases
were  further  purified by  passing them through  combination acti-
vated  charcoal/ molecular sieve  traps  and  all  flow  rates  were
periodically checked using a  soap film flow meter and timer.  Four
organic  compounds  used  in   the  study  were  methylene  chloride,
chloroform, carbon tetrachloride, and benzene. The  Tenax  GC  was
packed into cartridges  of three  different  diameters and lengths.
'  3 size data for each cartridge  is summarized in Table IX. Adsor-
ption and  retention data were obtained on each  cartridge separ-
ately. The  column was routinely  conditioned  with N2 gas purqe at
250 C for IS hours aflei. several  days of  runs.   At such time, the
cartridge was  disconnected  from  the  detector  in  order to prevent
the contamination of the latter.
     The  injection port  and   the  detector were  maintained  at  a
minimum of  5O C  above the maximum oven temperature.  This was done
to  prevent condensation  of   any  of  the  compounds  in  either the
injector  or the  detector.    Injection   was  done by  using  a 0.5
microliter  Hamilton  syringe   (groove  in  needle)   and a low volume
injection assembly.  This placed  the  0.05 microliter liquid sample
of  adsorbate in  vapor   form  (O.06 ml  of vapor  in 30  ml/min  of
carrier  gas)  on  the  cartridge as  a  plug.    The  breakthrough and
retention  volumes  were  determined   by  monitoring  the  times  of

initial elution (1.5 per cent of peak maximum) and peak maximum
respectively. The volume of carrier gas transmitted in each case
through the cartridge was calculated by multiplying the accurately
known volumetric flow rate (ml/min) by the corresponding time
(rain) . The normalized breakthrough volume (V"N) and retention
volume (V ) were calculated from the respective data, the
known Tenax" GC density, and the bulk volume of adsorbent in each
cartridge. VN is the initial elution volume/bulk adsorbent volume
(ml carrier/ml, adsorbent) and VN is the carrier volume at peak
maximum/bulk adsorbent volume (mlmcarrier/ml adsorbent).
Readings were taken with the Tenax GC cartridge maintained at
various fixed temperatures usually within an overall temperature
range of about 3O C. All temperatures were below 100 C and were
chosen for optimum retention time, recorder response, and reason-
able peakwidths (less than 2 rain) .

Cryogenic Loop Experiments

Substantial modification was done to the previous system in
order to perform experiments using the cryogenic loop. Figure 7
presents a schematic diagram of the apparatus. The same gas
chromatograph was used as in the previous experiments. The adsor-
bent cartridge was the 1/4" O.D. cartridge used in the liquid
injection experiments. The GC column was a 1O meter long Carbowax
2OM coated glass capillary column. A carrier gas flow rate of 1
ml/min was maintained through the GC column at all times and it
was periodically conditioned at 155°C for at least one hour. The
gas standard was prepared and stored in a 1O liter stainless steel
cylinder as described above. Finally, the cylinder and its
regulator were covered with heating tape and insulation so that
they could be heated and maintained at a constant temperature of
60 C to limit adsorption in the system. The cylinder was then
connected to the rest of the apparatus as shown in Figure 7.
The two positions of the six port valve are shown in Figure
8, detailing the connections operative in each position. Position
A is the mode in which pollutants which break through the adsor-
bent cartridge are trapped in the cryogenic loop. At this time,
the loop is immersed in a liquid N_ bath and the adsorbent is
maintained at ambient temperature (21 C) . Diluent gas at 30
ml/min is allowed to flow through the cartridge while the vacuum

the diluent gas stream at 2 ml/min so that a total of 32 ml/min of
polluted diluent gas flows through the adsorbent cartridge. The
concentrations of the individual compounds thus impinging on the
adsorbent in the cartridge are given in Table X. The time is noted
so that only a desired volume of gas is sampled. At this point
the six port valve is switched to position B, the analysis-
desorption mode. Simultaneously, the cryogenic loop is rapidly
heated to 100 C and the GC oven temperature program is initiated.
This performs the analysis on the contents of the loop.
The gas standard flow is shut off and the adsorbent cartridge
is heated to 200 C so that the diluent gas flow acts to desorb the
pollutants from it. The whole process of loading the cartridge,

trapping  the  pollutants,  analysing  them,  and  desorbing  the
cartridge is repeated for different sampling volumes.
     There are several differences between the system used in the
present experiments and the  one used  in  the  initial liquid injec-
tion experiments.  One  liquid  injection  port was removed in order
to  accomodate  the  six  port gas  sampling  valve  which was  then
maintained  at  120°C.    A second  injection  port was  converted to
accomodate  an  aluminum  heating block for desorbing the adsorbent
cartridge.  The original  heating  element  of  the injection assembly
was replaced by  two  longer ones capable of  maintaining a uniform
temperature of  200°C  throughout the block.   The original thermo-
couple sensor was retained.
     The  carrier gas was  changed from  nitrogen to  helium.  This
change was  imperative because  of  the  tendency of the nitrogen gas
to  liquefy  in  the cryogenic loop, giving  rise to  two problems.
Firstly, it blocked the loop and caused discontinuity of gas flow.
Secondly, the sudden vaporization  and consequent expansion of the
liquified N_  in  the  loop during desorption  made it impossible to
deposit the pollutants  onto  the GC column as a concentrated plug.
It  resulted in  a diffused  mixture  of  N2  and pollutants  being
presented for analysis which, in turn, made sharply defined chrom-
atographic  peaks impossible  to obtain.   It  was also necessary to
apply  a  slight  vacuum   (15  mm Hg,  745  mm  Hg  absolute pressure
operation) at the vent line  of the six port valve.  This served to
maintain  a  constant flov;  of helium  diluent  gas by counteracting
any head  loss  in the line,  and also prevented  any N_ impurity in
the helium  from  condensing in  the  line.   The diluent gas flow was
monitored by  using an  on-line capillary flow meter.   After the
flows  of  diluent gas  and gas standard were  set using the respec-
tive  needle valves,  they   were  checked periodically   using  the
capillary  flow  meter.    All  the  lines through   which  the  gas
standard  was  allowed  to flow  were  wrapped  in heating  tape and
maintained  at  60°C  to  limit  adsorption  in the  lines.   Blank runs
were done (without any pollutant gas standard but with carrier gas
flow)  to  check whether any  pollutants  from  the carrier or prior
runs were adsorbing  on  the  inner walls  of the  lines.   These pol-
lutants were not found  in concentrations large  enough to interfere
with  the  results of the  experiment  (less than  1%  of the concen-
trations of the  pollutants).
     The  log of  the normalized  breakthrough  volume and  the log of
the normalized  retention volume were plotted against 10 /T K for
each  halocarbon  and cartridge  type.   Typical  breakthrough plots
and retention plots are presented  in  Figures 9 and 18.   Tables XI
and XII  summarize the breakthrough volumes  and retention volumes
(ml/ml  of  Tenax  GC)   of  the  compounds   studied  on   the  three
cagtridges  for  four  representative  temperatures.   The  data for
20 C were obtained by extrapolation of graphs.
     The  breakthrough volume per  gram of Tenax GC, V ,  and reten-
tion  volume per  gram of Tenax  GC,  V     ,  were calculated. In all
cases  a  straight line was obtained "witn correlation coefficients
greater than 0.996 for  all data sets  except V., for benzene on the
1/8"  cartridge.   Relative agreement exists  Between the  data of
different cartridge sizes  for  each compound except that of carbon

tetrachloride.   The CCl^  retention data  for  the  1/8"  cartridge
exhibits brea? chrough and retention values appproximately 10 to 50
times  lower  than  the  corresponding 1/4"  or  3/8"  traps.    The
probable reason  for  this is a  non-linear  adsorption isotherm for
CC14  on  Tenax GC combined  with a  slow  rate of  adsorption  under
these  conditions.    Possible  reasons  for  this  anomaly will  be
discussed later in this section.
     It  is  also  interesting to point  out the anomaly  created by
the  extrapolation  of  the  benzene,  1/8"  cartridge data  to  20 C,
which  yields  a  breakthrough  volume  larger  than  the  retention
volume.  This, however,  is  well within  the limits of experimental
error. A comparison of  the  breakthrough  and  retention volume data
with that of previous studies is presented in Tables XIII and XIV.
The methylene chloride  values agree with values  obtained by Brown
and Purnell(5) but lie approximately a factor of three higher than
data  reported  by Bertoni et al.(6)   The chloroform data,  on the
other hand,  seems  to be in agreement with both  groups,  Brown and
Purnell(5)  and Bertoni  et al{6) and these  CHCl,  results also show
the most constant  pattern  between  the different cartridge  sizes.
Carbon tetrachloride again  shows a  very  low  capacity for the 1/8"
column,  data which  was repeatedly  obtained  in  multiple  experi-
ments.   It  is  interesting  to observe that the CCl^ data of Vidal-
Madjar et  al(7)  lie between the values  obtained  for the 1/8" and
the 1/4  or  3/8"  traps  in this  study.  Vidal-Madjar's values, with
the previous exception, consistently lie below the reported values
for halocarbons on Tenax GC by approximately a factor of ten.  The
results of Brown and Purnell(5)  on the other hand, appear approxi-
mately two times larger than those obtained in this study for CCl^
on Tenax GC with the two larger traps.
     The comparison of  the breakthrough  volumes for  benzene on
Tenax GC shows relatively  good  agreement with the values reported
by Butler  and Burke(1)  for a 4" length  column.   While the reten-
tion  volumes are an average of 25% below the values  reported by
both Gallant et  al(8)  and  Brown and Purnell(S),  they  are  in good
agreement with data reported by Janak(9).  These values are under-
standably  lower  than the  maximum  capacity per  gram of  Tenax GC
reported by Butler and Burke(1)  who used longer and more efficient
columns.
     Increase  in  cartridge diameter, corresponding  to  a decrease
in  linear  velocity of adsorbate  and  carrier   gas through  the
adsorbent,  consistently shows   an  increase in retention capacity
with  the exception  ot  chloroform.   Brown  and  Purnell(5)  found
similar  decreases  in  retention volume  with  increases  in  volume
flow  rates  while Butler and Burke(1) reported  no differences for
capacities  on longer,  more efficient  columns.    Gallant et  al(8)
showed slight  increases in retention  volume   at increased  flows
for  three  compounds on  Tenax  GC,  but  indicated  tnat  it  was
probably due  to  concentration decreases.  Graphs of retention and
breakthrough  volumes  per gram  of  Tenax GC versus carrier  linear
velocity are  shown  in Figures 11,  12 and 13  for  the data obtained
in this study as well as that of other workers where this velocity
data could be obtained.

     The  cryogenic loop  experiments were  done  with a  view  to
confirming  the  results obtained  in  the liquid injection  experi-
ments conducted previously.   Experiments were conducted by  samp-
ling different volumes of diluted  gas standard ranging  from  1,000
ml '-.o 16,000 ml in  steps of  1000 ml.  The  resultant chromatograms
were analysed for  breakthrough  of the  four major  compounds  under
consideration.   The  results  of these  experiments were  compared
with  those predicted  by the  liquid  injection  method  for  that
temperature and  were  found  to  match  within an  error  of 5%  or
better.  This is summarized  in  Table  XV.
     Additional low temperature  retention  studies  were done  on
chloroform  and carbon  tetrachloride  at  14°C by the liquid inject
method  on  the 1/4"  trap.   Both  compounds  showed  initial  break-
through  almost  instantaneously,  24.6 ml  for CC14  and  67 ml  for
CHC1.,, long before elution was expected.  A small  amount of steady
bleed  of  the compound  to   the  detector  was observed  for  long
periods  of  time (hours) until the  GC oven  temperature was  rapidly
raised  to  80°C  when  the  remaining adsorbent eluted  within a  few
minutes.   One possible  explanation of this is  a  slow  rate  of
adsorption  and/or diffusion into the pores of the  Tenax  GC at the
lower  temperatures.   Thus  at  higher  carrier  linear  velocities
(shorter  residence times),  sufficient   amounts  of  time  are  not
available  for complete  equilibrium  adsorption  to be  attained.
These low temperature results indicate that a small fraction  (less
than 5%)  of the  total accumulated chlorocarbon  is  lost  via  early
breakthrough  at low temperatures.   The majority of the  pollutant
is retained by the Tenax GC.
     From  these  experiments  it  was concluded  that a  1/4  inch
diameter sample cartridge containing 0.4 grams of  Tenax  is appro-
priate  for  field collection  of  the pollutants determined  in  this
study,  when the  total volume of air sampled  was  approximately 15
liters.

REPRODUCIBILITY OF THE METHOD

     In  order to  test the reproducibility of the  entire  method,
from collection to final analysis, under field conditions,  a  group
of  eleven  pairs  of  replicate samples were  collected, using
separate sampling  systems.   These were taken as  regular samples,
with their  average, in most cases  reported for the values  on  that
day. The study was  done over a period of six  months,  to carry out
the trapping  under  a  wide variety  of weather  conditions.   Samples
were desorbed under the usual conditions,  and no  attempt was  raaue
to  analyze the pairs on the  same day.   This  assured that  the
day-to-day instrumental variation  would be  reflected in  the
results.  Sample storage before analysis ranged  from 1 to 20 days,
and analyses  within the  same  pair were  done up to 14 days apart.
The standard deviation of the method was calculated as the average
of the standard deviations of each pair. Where a  substance was not
detected in both of the replicates in a pair, it  was not included
in  the  calculation, so that the  standard deviation  would not be
appear to be much lower for those compounds detected infrequently.
The results, shown in Table  XVI, indicate that the relative stand-

ard deviation for each of the compounds averages  30%,  with carbon
tetrachloride showing a high deviation of 114%.   If  CC1.  is omit-
ted, the relative deviation is 20%.  Carbon  tetrachloride appears
in most  ambient  air samples at  a level which  is just above  the
detection limit of  the  system.  In this group of  samples  it aver-
aged 0.05 parts per billion.    Since CC1. shows  a  tendency to be
lost in  the desorption system,  the  decreased precision  for  this
compound is expected.  The concentrations  determined in this study
can only be regarded as minimum amounts present.
     A quality  assurance  protocol was  developed  as an  important
part of the project. This  covers each aspect  of the analysis,  from
collection  of  samples  to  final  data  tabulation,  and  is  shown in
Appendix II.

                         DATA AND RESULTS

     The  analytical  data obtained during the  project  is reported
in Appendix  III.  In  the  Appendix  III  tabulation of the 1979 data,
where  a  compound was  detected at  too  low  a  level for accurate
quantitation  it  is  reported  as  being present at  the  detection
limit of  0.01  ppb. Where a sample was not  taken,  or where it was
not possible to determine an individual compound because of equip-
ment failure,  the missing data is indicated by  '*0.00'. A value of
0.00 indicates that  the compound  was  not detected  at  the sensi-
tivity limits  of  0.01 ppb. A summary of the arithmetic averages of
concentrations detected  for  each  compound at each  site in 1979 is
given  in  Table XVII.  Figures  14-19 show  these averages  in  gra-
phical form.  Geometric averages  were also  calculated  in order to
provide a measure of  the  typical concentrations  of the analytes
which  is   less sensitive  to  the  effect  of  a few  high outlying
points. The geometric averages are shown in Table XVIII.
     It is apparent  from the data that  the  site in Batsto Village
has, as  expected, much  lower  concentrations  of  the  target  com-
pounds in  the atmosphere.  In  several mass  spectrometric analyses
naturally  occurring  organic  vapors-- oc -pinene and camphene--have
been found, but vapors from both industrial  and automotive sources
are low in comparison to other sites.  Only chlorobenzene seems to
be relatively  high in comparison to the levels of the other pollu-
tants at  the  site. A local source of  this compound was suspected,
but could not  be pinpointed.
     The  averages and data  reported for  Elizabeth include  four
samples taken  in January  at a nearby  site in Linden,  which was
moved because  a stack  located  on  the  same building appeared to be
generating organic vapors.  Elizabeth was notable  for  its average
benzene level  of  6.2 ppb which was the highest average level found
in  the project.  It  is  also  unusual  in  that,  on average,  the
benzene level  is  nearly as high as that of toluene.
     Averages  of  each  compound were taken  by day of  the  week at
each site. These  are shown in  Table XIX.   Averages  for  each  site
for three  month periods are shown in Table  XX.   Trends  in  this
data are not obvious. Elizabeth showed the highest benzene concen-
tration in the  January-March  and  July-September  quarters,  with
these quarters showing  levels two  times as  high  as  the others.
Rutherford showed a  peak  benzene concentration in  January-March
but it was not as high as the Elizabeth levels.
     For  several  months  the compound N,N-dimethylnitrosamine was
included  in  the  group of  target compounds.  However,  it  was not
detected in any sample either on the  GC or  GC/MS analyses.  Since
it  proved to be unstable  in  the cylinder   gas   standard,  its

          behavior  in  the trapping  and  dssorption could  not be  assessed.
          Therefore, no data were reported for this compound.
               On the other hand, chloroform and nitrobenzene appeared to be
          more prevalent than the reported data would  indicate.   Most of the
          GC/MS  analyses  showed these two  compounds  to  be present  at  low
          concentrations. Improvements in the  analytical  technique,  especi-
          ally the changes in temperature program and  GC column improved the
          detection of these compounds in the latter part of 1980.
               Arithmetic and geometric  averages for  Rutherford and Batsto
          during  1980  are tabulated  in  Tables XXI and XXII. The data  ob-
          tained  at these sites  confirms the  large  difference in  overall
          pollution levels between them.  Both  sites showed  an average tolu-
          ene level which was higher than any other  compound,  with  benzene
          about  two-thirds as high as  the toluene.  Rutherford showed levels
          of the most concentrated compounds which were at least three times
          higher  than  those  at  Batsto, except  for  chlorobenzene,  which was
          comparable at  the  two sites. This  relatively elevated concentra-
          tion of chlorobenzene was noted in the previous year also,  but its
          source  remains  unexplained.  The overall  average  concentration of
          the  seven most commonly  detected compounds  at the  sites during
          1979 and 1980 is displayed in Figures 20 and 21.
               The  data  from the  Staten  Island  sampling  in 1981 does  not
          seem to confirm the theory that much of the  volatile organic vapor
          content  of  the  air   in  Staten  Island    is transported  from  the
          industrial area  west  of the Arthur Kill.  The overall  levels of
          organic vapors  found  in the  two Staten Island sites were signifi-
          cantly  lower  than those detected  in northern Manhattan.  All  the
          compounds detected at levels above 0.1 ppb at  Travis  were higher
          in  Manhattan,  frequently  substantially higher.  Mariner's Harbor
          showed  higher  levels  than  did  Travis,  but lower than Yorkville in
          Manhattan, except for tetrachloroethylene, which was 2 ppb at both
          sites.  The  average levels found  at  these  sites  are graphed in
          Figures 22, 23, and 24.

          WIND AND CONCENTRATION RELATIONSHIPS

               The  relationship  between wind  direction  and  the  average
          concentrations  for  the roost  frequently observed  compounds,  ben-
          zene,  toluene,  xylenes,  chlorobenzene, trichloroethylene  and
          tetrachloroethylene is displayed  graphically  in Figures  25 to 32.
          Meteorological  data  from  Newark  Airport was  used to obtain  the
          wind direction during  the  24 hours of sample  collection.  Samples
          taken  on  days when  the wind did not  vary out  of a single  95
          quadrant during collection were selected from the year's samples.
          These  samples were classified into four quadrants centering on the
          northwest, southwest,  northeast and  southeasterly wind directions
          respectively.  A finer 45    division  was not  deemed advisable, as
          the numbers of  samples  in  each  group  became too small for statis-
          tical  significance.   All  samples at the  individual sites  showing
          this consistent wind pattern were averaged for each compound.  The
          circle  in each diagram  signifies 0.5  or 5.0  ppb by volume, as
          labeled, with the origin equalling zero concentration.

     The  most  interesting  trends  arising  from  this  "pollution
rose" treatment are evident at the South Amboy site.   Every one of
the  eight compounds  plotted shows  the  highest  average  concen-
tration being  brought in  on winds from  the northeast.    In  that
quadrant   lie  the  heavily  industrialized  urban  regions  of
Elizabeth, Linden, Perch Amboy,  etc.
     The  sampling  locations  of  Elizabeth, Newark and  Rutherford,
for which the Newark Airport Meteorological data is  also  relevant,
show more even distributions of  the pollutant  levels with  wind
Direction.   The Elizabeth site does show consistently lower  pol-
lution levels when winds  are  from southeast.   This  site  in Eliza-
beth is  actually located  near  the Linden-Elizabeth border  about
one quarter mile east  of  the  Goethals Bridge,  northwest  of Staten
Island.
     While this method permitted  pollutant concentration analysis
with respect  to wind direction,  data could only be used  when the
wind direction  did  not vary  out  of the quadrant during  the  day.
This limitation excluded  the largest  fraction  of  the  data.   A
scheme was devised  to utilize all the data collected at  the  each
site over the period  of  sample collection.   This scheme  and the
results obtained  are comprised  of all  the data we obtained.   Ac-
knowledgement is icade  however that in unique cases the assumptions
utilized  may  lead   to possible  error.   Interpretation  of  the
results includes discussion concerning this possible error.
     Data on  the average  wind direction during  3 hour  periods was
obtained  from  the  Newark   International  Airport  Meteorological
Station and  from  the  Philadelphia  International Airport  Meteoro-
logical  Station  for   each  sampling day.    Wind  directions  were
classified  into  8  vectors:  north, northeast,  east,  southeast,
south,  southwest,  west,  and northwest.    For  example,  a  direction
of east was  assigned  when the wind wss  within the angle  sector of
90   +_  22.5   according to  the United States Meteorological Service
data.
     These  3 hour  average  wind  directions  corresponded to  the
specific  sampling  time frame of each day  and  a  number,  WN(1)  was
then calculated for the  number of 3 hour  periods  that  the  wind
orginated from  a given 45 degree  sector.   The index  I  varied  from
1 to 8  and corresponded  to the wind ••".irectionc  north,  northeast,
east continuing through northwest respectively.  An  example of the
number of periods corresponding to each  wind direction  fcr  a  24
hour sample might typically  consist of  4  from the south,  WN(5),  2
from the  southwest  WN(6)  and 2 from  the  northwest  WN(8), all  to
other WN(I)  would be then zero.   Newark airport data  was utilized
lor  the  sites:  Rutherford,  Newark,  Elizabeth  and  South  Amboy.
Philadephia  meteorological  data  was  used for the  Batsto Village
(Pinelands) and Camden locations.
     The  average  concentration  of  each pollutant  for a  specific
day  and site was then assigned with  equal weight to each  3  hour
wind directions for  that day and  site.   This  is  an  assumption
which  states  that  the   pollutant concentration  for  each  wind
direction was the same over  the course  of sampling  period.   While
this is not usually the case, the wind directions usually remained
consistent over a given  sampling period, for  example,   from the

south or  southwest 75  % of the  time in the  above  illustration.
Averaging similar  to  this  over a large number of days,  60 or 120
in this  study will,  in  general,  tend to eliminate  or  cancel the
singular errors from a given day.
     The assignment of concentration  to  wind direction  for  each
pollutant is  done  by multiplying the  Wind  Vector Number WN(1)  by
the average concentration,  X:
          WN(1)  x  X  =  CF(I)  concentration  factor  for  each  wind
     direction (I), pollutant,  f.ite and day.
Again, I equals 1 to 8 correspo iding to the wind directions.
     These concentration factocs  CF(I) were then summed for  each
wind rection  over  all sampling days for a  specific  pollutant and
site for each wind direction (I), giving:
          SUM CF(I) where I equals 1 through 8, for  each pollutant
     and site.
     The sum of concentrations factors for each wind direction was
then divided by the sum  of  the Wind Vector   numbers  SUM WN(I) for
all days  at a given  site  to  yield  an average  pollutant concen-
tration from each wind direction.  This sum of wind  vector numbers
is  simply   the  total  number  of  3  hour  periods that   the  wind
originated  form  the direction, I  ,  on all sampling days for the
sites using the Newark or Philadelphia data.
     The  data  from  this  analysis  is  presented in  Figures  33
through  44  for  the  sites  Rutherford,  Newark,  Elizabeth,  South
Amboy,  Camden and  Batsto  (Pineland),  for  seven pollutants  that
were measured  routinely  at  the sites.  The  specific species  are:
trichloroethylene,  tetrachloroethylene,  benzene,  toluene, chloro-
benzene,  para  and meta-xylenes  and  ortho-xylene.  The  numbers
assigned to the vectors  in  the figures are the average concentra-
tion frcm that wind direction.
     The average  concentration for  the sampling day  is assigned
initially to  all of the  3  hour wind dirctions.   The way an error
can be introduced using this assumption may be best  illustrated by
the following  example.  A  set of  3  hour wind  direction vectors
showing 1 from  the north and 7 for  the  combined  south and south-
west  is  observed.   There  is a possibility  that all  of specific
pollutant found on  that  day  was due to the north direction.  This
would unfairly weight  the directions  from  the  south  and southwest
too heavily and from  the north too  liqhtly.   On  the  other hand it
is  felt that  the  averaging  over  a  significant number  of  days
samples at  each location  would  tend  to  cancel  out this type  of
error to a  large extent. Exceptionally  high  pollutant concentra-
tions- 2Dove ten tinies tlie 2versus- were el^tninated  fzront this  wind
analysis to reduce  improper weighting  of the data.
     Looking  at  the data, one notices that the  South  Amboy  site
exhibits larger  vectors from  the  northerly directions  than  from
any other.  A check on the validity  of  this  weighting comes  from
comparison of  the  wind vectors for the  four  quadrants  using  data
only when the wind remained within the 90 degree sector throughout
the sampling  period.   One  can see  that  the  four sector limited
analysis South  Amboy data are markedly similar  to   that  of the 8
sector analysis  using all  the data.   Similar, but  not  identical
comparison, patterns are also shown at the other sites.

                The  actual  performance of  these  initial  statistical  wind
           versus  pollutant  concentration  analysis  has  suggested  several
           improvements.   The present  analysis,  however,  provides the FIRST
           data of any kind  for these organic vapors,  in ambient air.
                Meteorological  analysis  was initiated  on  a more  detailed
           basis  (hourly wind data)  for  the samples  collected  and analyzed
           from  the  Mariners Harbor and  Travis Sites on  otaten  Island,  NY.
           This analysis was performed  uy Dr.  Nathan Reiss of the Department
           of Meteorology  and Physical  Oceanography, Rutgers University,  New
           Brunswick, NJ.  as consui*-?nt to NJIT.   The study involved statis-
           tical  analysis  of hourly surface wind data from  the  nearby U.S.
           National  Weather  Service Station at Newark Airport.  The analysis
           was performed for ten compounds at the Mariners Harbor  site and 11
           compounds  on  the  target list at  the Trc\vis site, for all samples
           collected  up to  mid-April   1982.     Correlations  were  computed
           between the  24-hour concentration of each compound and the number
           of hours  that  the wind blew from  each  ten degree  sector during
           that 24-hour  period.   Because of the non-normality of the distri-
           butions of both  the concentration and  wind  data,  the Spearman Rank
           Correlation,  a  non-parametric  statistic,  was employed. The resul-
           ting  correlations are  presented  in  the  form  of  polar coordinate
           plots  in  Figures  45  through 65.   A corrtslat'.on of  about  0.7 is
           required  for  statistical significance at  the  five percent confi-
           dence  level.   This technique  has the  advar... .ge of making optimum
           use of the detailed wind observations  that are available, despite
           the  fact  that  the pollutant observations  themselves  have  only a
           24-hour time  resolution.
                Although these results are only for  a short  sampling dur-
           ation,  some   features may be noted.   Benzene,  styrene, xylene and
           ethylbenzene  at Travis are  positively correlated with winds from
           the  southwest.    Toluene,   styrene  and  p-xylene  are  positively
           correlated  v' th  winds  from the  north.    Tetrachloroethylene  ex-
           hibited higher  levels when  winds were out of  the westerly direc-
           tions  and trichloroethylene showed  higher  levels with winds from
           northwest, again  for the Travis site.
                Mariners Harbor  data  show that ethylbenzene  and  styrene
           appear  to have  higher  levels  with  winds  from  the southwest with
           all the aromatic target species  (non-chlorinated) also exhibiting
           higher levels when wind.? were from the northeast.  The halocarbons
           trichloroethylene and  tetrachloroethylene  also  appear  to  show
           higher  levels  in  the  air when  winds  are  from  either  the south-
           westerly  or northeasterly directions.
                This  meteorological  analysis  is certainly preliminary  in
           nature, but   indicates that  capabilities  exist  for other research
           in determination  of spatial  and temporal patterns  in the data.

           COMPARISON WITH  OTHER STUDIES

                A relatively small number of studies  on  the levels of known
           or suspected  volatile organic compounds in the ambient atmosphere
           have been  published.
                The  reported levels of  carbon tetrachloride  in areas where no
           local  contribution  is  expected  are,  for  example,  consistently

           close to 0.1 ppb at several widely separated locations.  Our values
           are  frequently  lower  than  this, due  to  losses  in analysis,  as
           discussed earlier.   Other compounds  are reported at more varied
           levels  probably due  to  nonconstant  emission  by  sources.    For
           example, the concentration of benzene and  toluene  in  air,  arising
           from  nearby  automobile  sources,   has   been  reported  at  levels
           ranging from 2  to  over 100 ppb.  The levels  reported  reflect the
           character of  the  area  sampled.   Benzene  levels  of  25 ppb  in  an
           urban area and 0.4 ppb in a rural wooded area show a difference of
           nearly  two   orders  of magnitude.    Values  found  in  this  work
           generally follow patterns and levels  similar to those reported in
           other  regions  of  the  country  where  data  are  available  for
           comparison.
                A comparison of the average levels  of t.etrachloroethylene and
           trichloroethylene with those reported by other workers is shown in
           Table XXIII.  The  comparison indicates   that  the  industrial  loca-
           tions  sampled  in  New  Jersey show,  in   general,  similar  or  just
           slightly  higher average  concentrations  for these  species  than
           those  reported  for other regions of  the United States.   This  is
           not unexpected,  because these values are average concentrations of
           a sampling  location  and encompass variations in  wind  and  weather
           over a 12 or 24 month period.
                A comparison of average benzene  levels  for tne areas  in this
           study  with  other  values  reported  in the  literature  is shown  in
           Table XXIV and toluene in Table XXV.  These averages show that the
           New Jersey  locations studied did not  exhibit unusually high aver-
           age  levels  of benzene  or toluene,  which can emanate  from vehic-
           ular, as well as industrial sources.
                The  small  sample size  (concentrate  from  only  one  to  two
           liters of air)  utilized  in  this study resulted  in optimum  chroma-
           tography and  qualitative identification but  also  provided relat-
           ively  high   detection   limits   of  approximately  50 ppt.    These
           detection  limits   prevented  observation of  many  of  the  target
           species  in  this study when  they were  at  or below these  limits.
           The compounds tetrachloroethylene,  trichloroethylene,  benzene and
           toluene are  included in  Tables  XXIII  through XXV  because of their
           high, frequency  of  observation  in our analysis and  the  relatively
           large number of reported concentrations   for these compounds in the
           literature.
