EXECUTIVE SUMMARY
In carrying out the Toxic Substances Control Act (TSCA) mandate, predictive
mathematical models are often used to estimate air concentrations of chemicals in the
indoor environment or to assess human exposure. The simple dilution model
calculates air concentrations as a function of the air exchange rate and the emission
rate of the chemical. The model assumes that no pollutant is lost within the chamber
from any mechanisms other than by dilution or exfiltration. The effects of other
mechanisms on the model, however, may be appreciable. Often referred to as "sinks,"
such mechanisms include chemical decomposition, chemical reaction, and mass
transfer between the gas or vapor phase and solid surfaces.
The objectives of this project were twofold. First, experimental tests in a test
chamber were performed to assess the sink effects of selected surfaces and building
materials on the concentrations of an indoor air pollutant. Second, the significance of
these sink effects to existing predictive mathematical models of indoor air pollutants
was to be determined. This final report presents the data for 12 experimental runs
using one chemical, p-dichlorobenzene. Results of 11 of these runs are presented in
the body of the report. Due to problems in run 11, all data and results pertaining to
that run are suspect and are presented separately in Appendix H.
Experiments were conducted in a room-size (1,261-ft3) test chamber at MRPs
Air Consumer Exposure (ACE) Laboratory under stable environmental conditions.
Interior surfaces were covered with gypsum wallboard. The wallboard was sealed with
. ready-mix joint compound and painted with one coat of interior latex primer and one
coat of semigloss interior latex paint. The 12 runs encompassed three tests each of
the following configurations; empty test chamber, test chamber with carpeting, test
chamber with carpeting and drapes, and test chamber with carpeting and a full-size
bed covered with a comforter.
p-Dichlorobenzene (PDCB) was selected for study because it is widely used in
the indoor environment as an insecticide (moth repellant), a disinfectant, or a
deodorant (room freshener). It was also selected to minimize the sink effects from
chemical reaction or degradation mechanisms, allowing the study to focus on
adsorption and desorption mechanisms.
PDCB and a tracer gas, sulfur hexafluoride (SF6), were simultaneously injected
at controlled emission rates into the test chamber. A continuous sample of test
chamber air was collected at the outlet. Aliquots of test chamber air were analyzed
IX
-------
using a Varian 3700 gas chromatograph equipped with a Carle automated gas
sampling system. After both compounds were maintained at a steady-state
equilibrium for a 6-h period, injection was stopped. The decay rate of PDCB relative
to that of SF6 was determined to assess the adsorption and subsequent desorption
characteristics.
Statistical analyses were performed to quantify SFe and PDCB decay curves
under each test configuration. Sink effects were estimated by comparing these decay
curves in a pairwise fashion.
Sink effects were observed in all experimental runs; that is, PDCB air
concentrations measured after the source was removed exceeded that predicted by
the simple dilution model. The most likely source of excess PDCB was from the
chemical's adsorption to the walls, drapes, carpeting, bed, and comforter during the
experiments and subsequent desorption and reentry into the air. No other possible
source was identified.
The maximum difference between PDCB air concentrations predicted by the
empirical model fitted to the measured data and those of the dilution model were:
0.9 ppm in the empty chamber, 1.6 ppm in the test chamber with carpet, 7.9 ppm in
the test chamber with carpet and drapes, and 2.6 ppm in the test chamber with carpet
and bed.
In the presence of sinks, a higher number of air exchanges was required to
reduce PDCB air concentrations within the test chamber to background levels after the
source of the contaminant was withdrawn. As an example, the models fitted to the
PDCB data in the presence of sinks and the model described by Eq. 3 were used to
calculate the number of air exchanges required to reduce the air concentration of
PDCB from 14 ppm to 2 ppm. Under the assumption of no sink effect, it would
require 1.95 air exchanges to reduce the PDCB concentration from 14 to 2 ppm.
However, the average number of air exchanges calculated from the models for the
empty test chamber was 2.50. The average number of air exchanges required in the
carpeted chamber was calculated to be 3.27. The average number of air exchanges
required in the chamber with carpet and drapes was 6.64, while that for the test
chamber with carpet and a bed was 3.75. Thus, the first-order decay model (Eq. 3)
would significantly underestimate the number of air exchanges necessary to reduce air
concentrations to background levels. As shown in this study, the sorption of PDCB
onto chamber surfaces and its subsequent desorption was significant relative to the
PDCB levels in the room air. Therefore, sink effect terms should be incorporated into
predictive exposure models. Additional modeling of the data base generated during
this study should be undertaken. Fitting other models to these data, based on some
type of equilibrium adsorption phenomenon or other physically-based concept, should
be attempted.

SECTION 1
INTRODUCTION
The Toxic Substances Control Act (TSCA) mandates the assessment of risks
associated with the manufacture and use of new and existing chemicals. In 1985, the
Interagency Committee on Indoor Air Quality called for developing an understanding
of human exposures to indoor air pollutants, the contributions of various energy
conservation measures, and the impact of introducing new consumer products and
building materials. This effort requires assessing exposure to chemical releases from
consumer products and building materials in indoor environments under various
conditions.
Due to the number and variety of products on the market, it would be extremely
costly to rely exclusively on the monitoring of indoor air concentrations in order to
determine all possible exposure implications of these products. A preferable option is
the use of predictive indoor air quality models to estimate the air concentrations or
personal exposures that can be expected under various conditions. This report
covers 12 experimental runs conducted in the Air Consumer Exposure (ACE)
Laboratory at Midwest Research institute (MRI) to study the sink effects of
p-dichlorobenzene. Results on 11 of the runs are presented in the body of this report.
Due to problems in run 11, all data and results pertaining to that run are suspect and
are presented separately in Appendix H.
One of the most commonly used predictive mathematical models is the simple
dilution model. In a well-mixed chamber with a constant air exchange rate (A), the air
concentration of a nonreactive pollutant in air (CJ, generated at a constant emission
rate (G), can be predicted at time (t) by the following mathematical model (Dunn
1987):
Ct = G(1 - e'*1) / (AV) (1)
where C, = air concentration at time (t)
G = emission rate
A = air exchange rate
Q = ventilation rate
V = exchange volume
t = time
-------
The. air concentration of the pollutant approaches a steady-state condition as
the change in concentration over time (dC/dt) approaches zero. At this steady-state
condition (t-»«), Eq. 1 reduces to:
C = G/(AV) for t -»oo (2)
After the source is removed, the air concentration decays exponentially and is
defined by the following equation:
0,-Cotf" (3)
where C0 = initial air concentration at t=0, the time at which the source is
removed
The dilution model assumes that no pollutant is lost within the chamber from
any mechanisms other than dilution (e.g., through chemical decomposition, chemical
reaction, or mass transfer between the gas or vapor phase and solid surfaces inside
the chamber). These other mechanisms are often referred to as "sinks." The dilution
model also assumes that the inlet air stream delivers "clean" air to the chamber at the
same temperature and pressure as those of the outlet stream and complete mixing of
the chamber air.
The application of the dilution model to predict exposure to a pollutant in an
indoor environment is complex if materials such as floor and wall coverings, window
drapes, and upholstered furniture appreciably adsorb or absorb the pollutant. For
purposes of this study, "sink effect1 is defined as the mass transfer of an air pollutant
between its gas or vapor phase and any surfaces inside the chamber. The adsorption
of the nonreactive pollutant to, and subsequent desorption from, nonreactive surfaces
is assumed to be a reversible process.
The estimation of exposure to a particular pollutant is complex if this sink effect
is appreciable. In fact, the sorption and subsequent desorption of certain pollutants in
building materials may be significant in relation to the amount of contaminant present
in the room air. Although the rate of buildup of the air concentration may be slowed
by the sorption phenomenon, the decay rate of the air concentration after the primary
source is removed may potentially affect the duration of exposure. Therefore, it could
be important to incorporate sink effect terms in predictive exposure models.
The study reported herein was performed over a three and a half year period.
First, a pilot study was undertaken in August of 1988 (the results of that study are
reported in Appendix A). In April of 1989, runs 1 through 6 were performed in the test
chamber with and without carpet. Runs 7 through 9 were completed in the test
chamber with carpet and drapes in June of 1990. In October 1991, the last three runs
were performed in the test chamber with carpet and a bad. Runs 1 through 6 were
conducted according to the Quality Assurance Project Plan (QAPjP), Revision 2, while
-------
runs 7 through 12 were conducted according to the QAPjP, Revision 3, which
incorporated modifications to GC parameters to improve detection limits for both
PDCBandSF6.
The report is organized in 13 sections. Section 2 presents the study objectives.
Section 3 describes the design of the study that was formulated in the QAPjP. The
design of the ACE Laboratory facility and environmental parameters are presented in
Section 4. Section 5 presents the methodology used to sample the air in the
chamber. The analytical procedures used for the analysis of SF6 and PDCB in air are
presented in Sections 6 and 7. The data acquisition methods and data analysis
approach are presented in Sections 8 and 9. Section 10 includes the results and
discussion. Quality assurance for the study can be found in Section 11. Finally, the
conclusions are presented in Section 12. References are listed in Section 13. All
supporting material and data are presented in a series of eight appendices.

SECTION 2
STUDY OBJECTIVES
The objectives of this project were to perform a series of experimental tests in a
room-size test chamber to assess the sink-effect characteristics of indoor air pollutants
on selected surfaces and building materials and to determine the significance of these
sink effects to existing predictive mathematical models of indoor air pollutant concen-
trations. The study focused on the influence of combined sink effects on the air
concentration of specific pollutants versus time in a test chamber constructed of
common building materials. p-Dichlorobenzene (PDCB) was selected as the test
compound. This chemical allowed the investigation to focus on adsorption and
desorption mechanisms. The sink effects from chemical reaction or degradation
mechanisms were minimized.
Determining the relative contribution of all potential sink-effect mechanisms
(e.g., chemical reaction, degradation, sorption) that may occur was beyond the scope
of this study. This study made no attempt to isolate, identify, or quantify specific sink-
effect mechanisms.

STUDY DESIGN
3.1 PROJECT DESCRIPTION
This study was conducted in a room-size test chamber at MRI's Air Consumer
Exposure (ACE) Laboratory, which simulates a residential room where household
consumer products would be used. p-Dichlorobenzene (PDCB) was selected to be
the first indoor air pollutant to be tested. PDCB is widely used in the indoor
environment as an insecticide (moth balls), a disinfectant, and a deodorant (room
fresheners). Sulfur hexafluoride (SF6) was used as the reference tracer gas.
The complete study consisted of 12 experimental runs using four configurations
of the ACE laboratory:
• 3 runs in the empty test chamber,
• 3 runs in the test chamber with carpet,
• 3 runs in the test chamber with carpet and drapes, and
• 3 runs in the test chamber with carpet and bed.
Triplicate experiments were conducted in the test chamber configured with all
interior surfaces made of gypsum wallboard (runs 1, 2, and 3). All wall, floor, and
ceiling surfaces were covered with gypsum drywall except the door to the chamber, a
30-in x 30-in observation window, and two 12-in x 12-in ports, an inlet and an outlet.
The wallboard was sealed with ready-mix joint compound (Magnum Products R-100
and R-200 vinyl formulation), and all interior surfaces were painted with one coat of
interior PVA latex primer sealer (DeVoe No. 55201-50) and one coat of semigloss
interior latex (DeVoe No. 52549-50).
Next, triplicate experiments were conducted using the same configuration as
described above with the addition of wall-to-wall carpeting on the floor of the test
chamber (runs 4, 5, and 6). The carpet pile was made of 100% polyester (Burlington
Monticello M3776). No pad was installed underneath the carpet. The carpeting was
replaced after each test run.
-------
Triplicate experiments were also conducted using the same configuration with
carpeting as described above with the addition of 12 sets of drapes (runs 7, 8, and 9).
The drapes were manufactured by Burlington (marquis style, No. 71-2101) and were
purchased from a local retail outlet. Each drape measured 50-in wide and 84-in long
and were made of 72% rayon and 28% polyester. The drapes were hung on a free-
standing aluminum frame within the test chamber. Four sets of drapes were hung
along each long wall of the chamber, and two sets along each short wall. The drapes
and carpeting were replaced after each experimental run.
For the last three runs, the test chamber was outfitted with wall-to-wall
carpeting. A regular full-size Serta mattress on box springs was positioned in the
center of the chamber (runs 10, 11, and 12). The bed was supported by a metal
frame at 7 in from the floor. The mattress (Serta I.D. No. 940PS LUXMF FND 89505)
consisted of 45% cotton felt, 40% polyurethane foam, and 15% polyester fibers on a
wire spring unit. The box spring consisted of a wire spring unit covered with 100%
polyester fabric. The mattress was covered with a percale comforter consisting of
50% cotton, 50% polyester fabric and filled with 100% polyester fiber-fill. The carpeting,
bed, and comforter were replaced after each experimental run.
PDCB and SF6 gas were simultaneously released into the test chamber at
constant emission rates. The air concentrations of PDCB and SF6 in the outlet air
were measured at 6-min intervals. After the concentrations of both chemicals in air
achieved a steady-state equilibrium for a 6-h period, both sources were removed
simultaneously. Steady-state conditions were determined through observation of the
PDCB and SF6 area counts vs. time plots printed on the dot-matrix printer. The start
of equilibrium was determined as that time point at which area counts ceased to
increase.
The air concentrations of SF6 and PDCB measured at the time the sources
were removed are the initial concentration (C0) used in the decay model (Eq. 3) to
approximate a decay curve which is representative of decay caused solely by dilution.
The concentrations of SF6 and PDCB measured from the time the sources were
removed were plotted against time, and curves were fitted to the data. The empirical
decay curves for each chemical were compared to the theoretical decay curves
predicted by Eq. 3.
Experiments were conducted to determined whether SF6 conformed to the
theoretical decay curve predicted by Eq. 3 and to determine whether SF6 gas is a
suitable reference compound for the study. SF6 is a colorless, odorless, nontoxic, and
nonflammable gas. In the presence of most materials it is completely stable to
temperatures of about 400°F and has shown no breakdown or reaction in quartz at
900°F. SF6 is slightly soluble in water and oil (Compressed Gas Association 1966). It
is readily liquified and is shipped in steel cylinders as a liquified gas under its own
vapor pressure of about 320 psig at 70°F. This stable, inert gas has been used
extensively as a tracer for ventilation studies and for determinations of air exchange
8
-------
rates in air chamber studies. The empirical decay curves for SF6 were expected to
coincide with the theoretical curve for SF6.
The SF6 data were used to demonstrate that Eq. 3 represented the actual
decay of a chemical in the absence of sink effects under the environmental conditions
set for each test run. If Eq. 3 provides the best fit to the SF6 data, then sink effects
are demonstrated whenever the observed rate of decay of PDCB deviates from that in
Eq. 3. This is explained by the fact that a source other than the PDCB concentrations
in the air at time t = 0 (C0) are contributing to PDCB concentrations (C,) in the test
chamber air throughout the decay period. This would result in the measured air
concentrations exceeding those predicted by Eq. 3. The most likely source is PDCB
adsorbed into surfaces during the experiment, which subsequently desorbs and
feenters the air. No other source was identified.
The control of the temperature inside the test chamber can have a strong
impact on the emission rate of PDCB (Nelms 1987). The temperature and relative
humidity were controlled during each experimental run. Barometric pressure was
monitored but not controlled.
The experimental procedures and instrument parameters used for this study
were developed in a pilot study presented in Appendix A.
3.2 DESIGN OF ACE LABORATORY EXPERIMENTS
3.2.1 Instrument and Method Performance Objectives
The performance of the analytical method was characterized by evaluating the
accuracy, precision, limits of detection, and limits of quantification. Precision of the
sampling and analytical system, which includes instrument stability during analysis,
was monitored by performing replicate analyses of check standards of both SF6 and
PDCB at the beginning of each experimental run and by plotting the data on a control
chart. The precision was expressed as range percent (R%):
X, - X.
R% = 1 _ ^ x 100 (4)
where X, = highest value determined
X,, = lowest value determined
X = mean value of the set
-------
and
* = s t *>
where Xj = ith determination
n = number of determinations
For runs 1 through 6, the performance objective for precision (in terms of range
percent) was set at 15% for SF6 and at 25% for PDCB (QAPjP, Revision 2). For runs 7
through 12, the performance objective for precision was set at 15% for both SF6 and
PDCB (QAPjP, Revision 3).
The limit of detection (LOD) of the analytical system was defined as the
corresponding concentration of the SF6 or PDCB which has an area count equal to
three times the noise level from the GC detector. The performance objectives for LOD
specified in the QAPjP were 1.5 ppb for SF6 and 0.3 ppm for PDCB. For runs 7
through 12, the LOD for PDCB was lowered to 0.1 ppm.
The limit of quantification (LOQ) of the analytical system was defined as the
corresponding concentration of the SF6 or PDCB which has an area count equal to
10 times the noise level from the GC detector. The LOQ was determined to be 5 ppb
for SF6 for all runs. The LOQ for PDCB was 1.0 ppm for runs 1 through 6 and
0.3 ppm for runs 7 through 12.
Accuracy of the analytical method was established using SF6 and PDCB check
standards prepared in Tedlar sampling bags. These samples were prepared
independently of the standard series. The check standards were analyzed in
duplicate for each gas sampling loop prior to each experimental run. Accuracy, A%,
was estimated as:
A% = 100% + RE% (6)
where RE%, the relative error, is calculated as:
RE%=
where F = found weight of chemical
A = actual weight of chemical
10
-------
For runs 1 through 6, the performance objective for accuracy was set between
75% and 125% for PDCB and between 85% and 115% for SF6 (QAPjP, revision 2).
For runs 7 through 12, the performance objective for accuracy was set between 85%
and 115% for both SF6 and PDCB (QAPjP, revision 3).
3.2.2 Design of Measurement Processes
Real-time temperature, humidity, and barometric pressure measurements were
collected at 1-min intervals during all experimental test runs using WEATHERtronic
sensors mounted inside the ACE lab. A Compaq Portable computer recorded the
temperature, humidity, and barometric pressure data, together with the clock time,
onto an internal hard disk. An Okidata dot-matrix printer provided a hard copy of the
data in real time.
The humidity within the test chamber was measured with a WEATHERtronic
5120-B humidity probe in units of percent relative humidity. The humidity recording
equipment was checked against wet bulb/dry bulb thermometers traceable to NIST.
Calibrations of the humidity recording equipment were conducted prior to each
experimental test run. The relative humidity was adjusted to between 35% and 55%
and controlled within ±10%.
Temperature was monitored at two locations on the east wall of the test
chamber: at the sampling inlet located approximately 1.5 ft from the ceiling, and at a
level of 1 ft from the floor. The temperature measuring equipment was checked
against a set of certified thermometers (No. 9848) traceable to NIST. The type-K
thermocouples and Omega TAC-80 thermocouple-to-millivolt converters were checked
at the beginning of each experimental test run. The temperature was adjusted to
between 72° and 76°F and controlled within ±1.8°F.
Barometric pressure was measured at 1-min intervals with a WEATHERtronics
,7105-A analog barometer. The analog barometer was checked against a fortin-type
mercury barometer traceable to NIST. Calibration of the analog barometer was
conducted prior to each experimental test run. The barometric pressure was
monitored but not controlled.
A continuous sample of air was collected at the outlet of the test chamber and
injected at 6-min intervals into an automated Varian 3700 gas chromatograph (GC)
equipped with an electron capture detector (ECD), a flame ionization detector (FID),
and a Carle gas sampling system. The analog output of the GC was processed by an
analog-to-digital converter based on a Wintek microcontrol system module interfaced
with a Compaq microcomputer. The microcomputer was running a Microsoft BASIC
data logging and integration software program (ACE999, V09/22/88) modified
specifically for this project by MRI. The integration program was activated simul-
taneously with each sample injection. The data system automatically quantified the
chromatogram using preset processing parameters. The area counts and retention
11
-------
times of each peak were computed and printed on an Epson dot-matrix printer. The
GC data output and integration data were also saved to a hard disk. A Heath
(Model SR 204) strip chart recorder recorded the chromatogram and served as a
backup to the data logger.
The GC/ECD was calibrated using a series of SF6 standards prepared in Tedlar
gas sampling bags. Each Tedlar bag containing the SF6 gas standards was attached
to a Teflon sampling line and introduced into the GC through the 0.25-mL sampling
loops within 1 h after preparation using a Gast two-cylinder pump. Each standard
was injected four times (two injections per sampling loop). Each of the 0.25-mL gas
sampling loops (A and B) was calibrated separately. The GC/ECD was calibrated
over a range of 4 to 500 ppb prior to runs 1 and 7, and prior to each of the last three
runs.
The GC/FID was calibrated using a series of PDCB standards prepared in
Tedlar gas sampling bags. Each Tedlar bag containing the standard mixtures was
attached to a sampling port'and introduced into the gas chromatograph within 1 h
after preparation via the sampling loops. Each standard was injected four times (two
injections per sampling loop). The 1.0-mL gas sampling loops (A and B) were
calibrated separately. The GC/FID was calibrated over a range of 1 to 153 ppm PDCB
prior to run 1, for use during runs 1 through 6. The GC/FID operating parameters
were modified prior to run 7 to lower the LOQ from 1.0 to 0.3 ppm. The GC/FID was
then calibrated over a range of 0.3 to 74 ppm prior to runs 7, 10, 11, and 12.
Analysis of the test chamber air for SF6 and PDCB was performed in real time
at 6-min intervals. Area count measurements were started prior to the introduction of
both compounds into the test chamber and were continued throughout the air
concentration buildup period, a 6-h steady-state equilibrium period, and the period of
decay of the SF6 and PDCB air concentration (after removal of the sources). The area
count measurements ended when the air concentrations of both compounds fell
below their respective limit of detection.
3.2.3 Design of Quality Control Procedures for Measurement Processes
Check standards of both SF6 and PDCB were injected four times (twice per
sampling loop) into the GC before each experimental run to monitor the accuracy and
precision of the system over the entire project; the responses for these standards
were plotted on controls charts. The control limit for precision expressed as range
percent were set at 15% for both SFe and PDCB. The lower and upper control limits
for accuracy expressed in terms of relative error was set between 75% and 125% for
runs 1 through 6 and between 85% and 115% for runs 7 through 12. If the responses
of these check standards exceeded the control limits, the run was aborted and the GC
was recalibrated with the standard series.
12

3.2.4 Experimental Procedures
Four sets of triplicate runs were conducted with PDCB in the ACE Lab test
chamber for a total of 12 experimental runs. The following procedural steps were
used for each experimental run. Details on each step are presented in Sections 4
through 8:
• The test chamber was prepared using the appropriate setup for the
experimental test run;
• The temperature sensors in the test chamber were checked against NIST-
traceable thermometers;
• The temperature within the test chamber was adjusted to between 72° and
76°F;
• The WEATHERtronics 5120-B humidity sensor was checked against a
psychrometer with wet/dry-bulb thermometers traceable to NIST;
• The relative humidity within the test chamber was adjusted to between 35% and
55%;
• The WEATHERtronics 7105-A analog barometer was calibrated using a fortin-
type mercury barometer traceable to NIST;
• The SF6 and PDCB standards were prepared in Tedlar gas sampling bags;
• The Varian 3700 gas chromatograph was calibrated using SF6 and PDCB
standard series and check standards that were injected into the GC within 1 h
after preparation;
• The flow rate of SF6 gas was measured with a volumetric bubble meter;
• The exhaust blower of the test chamber was turned on and flow rate adjusted
to achieve an air exchange rate of approximately 1 exchange per hour;
• The initial weight of PDCB was determined on the Mettler PM-4600 top-loading
balance;
• The GAST vacuum pump was started to pull air from the exhaust outlet of the
test chamber through the autosampling loops;
• The ACE999 computer program was initiated to activate the autosampling
valves and begin the GC analysis of the test chamber air at 6-min intervals;
13
-------
• All analytical instrumentation, integrators, and data logging equipment were
checked to ensure that they were operating properly;
• The background air concentrations of SF6 and PDCB within the test chamber
were measured for approximately 30 min;
• SF6 and PDCB check standards were analyzed within 1 h after preparation.
• If check standards were found to be within the performance objectives
according to the QAPjP, the run was started.
• SF6 and PDCB were simultaneously introduced into the test chamber;
• The real-time chromatographic integration data (area counts) of both SF6 and
PDCB were monitored to determine the time when the air concentration of both
chemicals reached a steady-state equilibrium;
• After the steady-state equilibrium had been maintained for a minimum of 6 h,
the source of SF6 and PDCB were simultaneously removed from the test
chamber;
• The GC analysis of the test chamber air for SF6 and PDCB was terminated
when the concentrations of both compounds fell below their respective limit of
detection;
• The final weight of PDCB was determined using the Mettler PM-4600 top-
loading balance. The total mass of PDCB sublimed during the experimental run
was calculated by subtracting the final from the initial weight of PDCB; and
• After completion of each run, high-volume exhaust fans were turned on to air
out the test chamber for at least 48 h prior to the next run.
3.3 PROBABLE FATE OF PDCB IN TEST CHAMBER AIR
PDCB is a stable chemical at room temperatures and atmospheric pressure
and is not likely to react or decompose in air at a significant rate relative to the rate of
decay caused by the air exchange rate in the test chamber. Nucleophilic reactants
and hydroxyl radicals that are known to react with dichlorobenzenes are not expected
to be present in test chamber air.
Dichlorobenzenes, in general, were reported by Ware and West (1977) to be
reactive toward hydroxyl radicals in air with a half-life of approximately 3 days. The
reaction products and further details of such photooxidation reactions were not
indicated. p-Dichlorobenzene, specifically, was reported by Ware and West (1977) to
be resistant to autooxidation by ozone in air.
14
-------
No specific information pertaining to the hydrolysis of PDCB was found. Ware
and West (1977) reported that the inductive electronegative effect of chlorine
substitution activates the benzene ring, which makes such compounds more easily
attacked by nucleophilic functional groups, such the OH~. Morrison and Boyd (1973)
reported, however, that aryl halides are characterized by very low reactivity toward
nucleophilic reagents. As an example, the environmental conditions necessary for
hydrolysis of hexachlorobenzene to a pentachlorophenyl derivative were reported by
Patai (1973) to be the presence of ammonia at a temperature of at least 250°C. On
this basis, PDCB, which is less chlorinated than hexachlorobenzene and consequently
less easily attacked by nucleophiles, would not be expected to undergo hydrolysis at
an appreciable rate in the test chamber.
Information concerning the biodegradation potential of PDCB indicates that this
compound is very persistent and probably will be biodegraded very slowly by micro-
organisms. Evidence that PDCB is a persistent chemical is presented in a study by
Thorn and Agg (1975) which lists PDCB as a synthetic organic chemical unlikely to be
removed during biological sewage treatment, even after prolonged exposure of the
biota.
The EPA Air & Energy Engineering Research Laboratory (AEERL) conducted
experiments with PDCB in small, polished stainless-steel chambers and observed
transient sink effects from the walls (Dunn and Tichenor 1988). These "sink" effects
are expected to be greater in a test chamber constructed of gypsum wallboard.
The MRI test chamber is constructed of building material found in most
residences or office buildings using conventional construction methods. The chamber
is not expected to be airtight. PDCB will most likely leak through small cracks around
the door and windows; however, the leakage rate is expected to be constant and
insignificant relative to the amount of PDCB exhausted out of the chamber through the
exhaust outlet. The leak rate of PDCB will simply contribute to the overall air
exchange rate of the chamber. If the leak rate of the chamber had changed radically
during an experiment, it would have been detected by a change in the air concen-.
tration of the SF6 tracer gas within the chamber. A change in the leak rate would
cause the empirical air concentration data for SF6 versus time to deviate from the
theoretical curve discussed in Section 1.
The potential sinks for the PDCB in the test chamber are commonly used
building materials and furnishings in the home: painted gypsum drywall, synthetic-
fiber carpeting, synthetic fiber drapes, bed frame, mattress, box springs, and
bedspread.

3.4 BACKGROUND AIR CONCENTRATION OF PDCB AND SF6 IN THE TEST
CHAMBER
The ACE Lab test chamber was flushed continuously with air for at least 2 days
after each experimental run. Air samples were collected inside the test chamber and
analyzed prior to each experimental run to ensure that the test chamber had been
completely purged.
Before and after each experimental run, air within the test chamber was
analyzed by GC/ECD to determine potential background air concentrations.

SECTION 4
FACILITY DESIGN AND ENVIRONMENTAL INSTRUMENTS
4.1 PROJECT FACILITIES
This study was conducted in a room-size test chamber located in MRI's ACE
Laboratory (214/216-E). The test chamber is equipped with temperature, humidity,
and air exchange controls required to conduct consumer exposure studies under
stable conditions (Figure 1).
Preparation of the standards, blanks, and spikes was conducted in MRI's Air
Quality Lab (207-W). This laboratory is equipped with the necessary fume hoods,
analytical balance, and volumetric glassware required to carry out this task.
4.1.1 Test Chamber Volume
The volume of the test chamber in the ACE Lab was set at 1261 ft3. The room
has floor dimensions of 14 ft x 11.4 ft and a ceiling height of 7.9 ft. The room volume
remained constant for all experimental runs.
4.1.2 Instrumentation
The following instrumentation was used for the measurement of environmental
conditions within the test chamber air:
• MRI-built analog-to-digital converter based on Wintek microcontrpl system
module with 12-brt resolution and RS-232 host computer interface;
• Compaq Portable computer running Microsoft BASIC data logging program
(ACE 999, VO9/22/88);
• Heath (Model SR 204) strip chart recorders. Used for backup to the data
logger;
• Okidata Model 192 printer to record all logger operations;
WEATHERtronics SG-21 hydrothermograph;

-------
• WEATHERtronics 7105-A analog output barometer;
WEATHERtronics 5120-B portable humidity probe;
Thermocouples (type K) with Omega TAG 80 thermocouple-to-millivolt
converters; and
• WEATHERtronics Signal Conditioning Module File and Power Supply (Model
1018).
4.1.3 Relative Humidity
The relative humidity within the ACE Lab was monitored using a
WEATHERtronics 5120-B portable humidity probe. The accuracy of the
WEATHERtronic humidity probe was listed by the manufacturer as ±2% in the
operating range of 0% to 80% relative humidity. The instrument was tested and fully
calibrated at the factory.
The analog output signal of the humidity sensor was conditioned by a
WEATHERmeasure Humidity Signal-Conditioning Module (Model 1023). The
conditioned analog signal was processed by an analog-to-digital converter based on a
Wintek microcontrol system module interfaced with a Compaq microcomputer. The
microcomputer was running a Microsoft BASIC data logging program (ACE999,
V09/22/88) written by MRI.
The humidity probe was calibrated at a low humidity point of 12% inside a glass
container using a saturated salt solution of lithium chloride in water, and a high
humidity point of 75% using a saturated salt solution of sodium chloride in water.
Calibration of the humidity recording equipment was conducted twice, immediately
prior to runs 1 and 10. The humidity recording equipment was checked against a wet
bulb/dry bulb psychrometer. The thermometers in this unit were checked against
NIST-traceable thermometers. Instrument checks were conducted prior to each
experimental run.
4.1.4 Temperature
The temperature within the ACE Lab was monitored using two thermocouples
connected to an Omega TAG 80 thermocouple amplifier and linearizer. The
temperature probes were located at the sampling inlet and at approximately 1 ft from
the floor.
The accuracy of the Omega thermocouple-to-millivolt converter was listed by
the manufacturer as ±7.2°F over its entire operating range of 4° to 1832°F, The output
of the instrument was listed as 1 mV/°F. The analog signals from both converters
19
-------
were processed by an analog-to-digital converter based on a Wintek microcontrol
system module interfaced with a Compaq microcomputer.
The temperature probe was calibrated once over a much narrower operating
range (32° to 212°F) using ice water and boiling water to achieve an accuracy of ±1°F.
The temperature measuring equipment was checked against a set of certified
thermometers (No. 9848) traceable to the NIST. The type-K thermocouples and
Omega TAC-80 thermocouple-to-millivolt converters were checked against a mercury
thermometer traceable to NIST prior to each experimental run.
4.1.5 Barometric Pressure
The barometric pressure within the ACE Lab was monitored using a
WEATHERtronics 7t05-A analog output barometer located approximately 2 ft below
the sampling inlet. The accuracy of the WEATHERtronics analog output barometer
was listed by the manufacturer as ±0.08% over an operating range of 17.72 to
32.48 in Hg including hysteresis, thermal shift, and nonlinearity. The sensor was
tested by the manufacturer inside a pressurized chamber and compared to an NIST-
traceable standard. No adjustments to the sensor were necessary.
The analog output signal of the barometric pressure sensor was conditioned by
a WEATHERmeasure Barometric Pressure Signal-Conditioning Module (Model 1025).
The conditioned analog signal was processed by an analog-to-digital converter based
on a Wintek microcontrol system module interfaced with a Compaq microcomputer.
The analog barometer was checked against a fortin-type mercury barometer
traceable to NIST. Instrument checks were conducted prior to each experimental run.
4.1.6 Air Exchange Rates
Ventilation rates within the test chamber were controlled for all experimental
runs; air exchange rates were determined from the tracer gas decay rate.
For runs 1 through 6, air was exhausted from the test chamber with a General
Metal works (GMW) hi-vol blower equipped with Accu-vol flow controllers. The GMW
blower was calibrated prior to the experimental runs, and each time the brushes were
changed in the motor with the BGI Calibrating Orifice Assembly (MRI No. X-6695) and
a Dwyer incline manometer. The BGI orifice was calibrated on 4/18/85 against a
positive displacement rotameter. The calibration curve consisted of flow rate
measurements plotted against static pressure data.
Calibration of the GMW blower consisted of the following steps. A glass fiber
filter was placed on the filter holder of the hi-vol. The BGI orifice assembly was placed
over the filter and secured to the hi-vol with wing nuts. The hi-vol was then turned on
and allowed to stabilize for approximately 5 min. The water manometer was
20
-------
connected to the tap on the side of the BGI orifice assembly after the manometer
scale was zeroed and leveled. The static pressure was read from the manometer
scale in inches of water. The ambient temperature and barometric pressure were also
recorded. The static pressure was converted to flow rate in cubic feet per minute
using the calibration curve.
Prior to run 7, the exhaust system in the test chamber was changed to a Gast
rotary-vane, high-vacuum pump controlled with a critical orifice. The critical orifice was
sized to achieve a nominal flow rate of one air exchange per hour. This exhaust
system was deemed superior to the previous setup because it did not require
repeated adjustments and recalibrations for each experimental run once the critical
orifice was properly sized. This exhaust system was used for the remaining runs.
4.1.7 Air Mixing Within the Test Chamber
Air mixing patterns within the chamber affect the transport of organic vapors
from the source to the sampling inlet. This can affect the accuracy of air
concentration measurements within the chamber when using a single-point sampling
scheme. The mixing of air within the chamber can be influenced by the air exchange
rate through the chamber and by the presence of internal mixing fans or external
recirculating loops (Matthews 1987).
Air mixing characteristics within the test chamber were investigated using SF6
tracer gas to determine the air mixing conditions within the chamber. Air mixing was
achieved using two commercially available box fans. The fan housing was attached to
a chrome tubular stand which permitted height adjustments from 20 to 40 in high and
allowed the fan to be tilted at angles up to 180 degrees from vertical. The fan motor
was rated at 1/12th hp and could circulate air at 1000, 800, or 600 rpm. The fans
were positioned at adjacent corners of the test chamber along the back wall and were
facing the opposite corners of the chamber. The fan housings were 32 in from the
floor and tilted at approximately 30 degrees from vertical. The fan speed was
adjusted to 800 rpm. The air exchange rate of the test chamber was set at
approximately 1 per hour using the General Metal Works Hi-Vol blower and Accu-vol
flow controller.
SF6 was injected into the test chamber at a controlled flow rate to achieve a
steady-state concentration. Air concentration measurements were conducted at 27
locations within the test chamber as defined by a three-dimensional grid. The
sampling locations were determined by dividing the floor of the test chamber into nine
sections of equal area in a 3 x 3 pattern (Figure 2). Test chamber air was sampled at
the center point of each of these nine sectors at three heights from the floor. The low
(L), medium (M), and high (H) sampling heights as measured from the floor were
15.7 in, 47.5 in, and 78.7 in, respectively (Figure 3).

The air concentrations of SF6 at each of these sampling locations were
compared to the air concentrations measured at the sampling inlet located at the
exhaust outlet on the east wall of the test chamber. The calibration data used for the
mixing study are presented in Table 1. The results of the air mixing study are
presented in Table 2. The relative error of the SF6 concentration measurements at the
27 locations within the test chamber were within +3.31% and -2.86% of the air
concentrations measured at the sampling inlet. These results demonstrated that the
accuracy of the single-point sampling scheme in estimating air concentrations within
the test chamber is well within the data quality objective of ±10% as specified in the
QAPjP.
4.2 DELIVERY OF SF6 AND PDCB INTO THE TEST CHAMBER
Sulfur hexafluoride (98.8% pure) was delivered to the test chamber from a
compressed gas cylinder (Matheson Lot No. J61-0231-A3) via stainless steel or Teflon
tubing. The cylinder pressure was reduced from 320 psig to approximately 78 psig
using a two-stage pressure regulator (Matheson No. 8L 530). The pressure was
further reduced to approximately 17 in of H2O with a low pressure regulator (Matheson
No. 3701). The flow of SF6 into the test chamber was controlled by a double-pattern
fine-metering valve (Nupro No. SS-4MGD) positioned downstream from the low
pressure regulator. This fine-metering valve was used for accurate flow control below
1 mL/h. The flow rate of SF6 was adjusted to maintain the air concentration inside the
test chamber to below 500 ppb.
Prior to run 7, the SF6 gas supply was changed to Scott Specialty Gases
reference gas cylinder (No. XA1982) containing 10,000 ppm SF6 in air. The contents
of the gas cylinder was certified by Scott to be within ±5% of the labeled concentra-
tion. The cylinder pressure was reduced from 320 psig to approximately 78 psig
using a two-stage pressure regulator (Matheson No. 8L 530). The pressure was
further reduced to approximately 17 in of H2O with a low pressure regulator (Matheson
No. 3701). The flow of SF6 into the test chamber was controlled by a fine-metering
valve positioned downstream from the low pressure regulator. This fine-metering valve
was used for accurate flow control of approximately 40 mL/min. The flow rate of SF6
was adjusted to maintain the air concentration inside the test chamber to below.
500 ppb.
p-Dichlorobenzene vapor was generated in the test chamber by sublimation of
pure PDCB crystals. A 12-in x 10-in flat metal pan of PDCB crystals was positioned at
the air inlet. The emission rate of PDCB vapor was dependent on the surface area of
the solid crystals and the vapor pressure of PDCB. Due to a positive correlation of
vapor pressure of PDCB with temperature, the ambient temperature of the chamber
affected the emission rate. The emission rate of PDCB vapor was also dependent on
the air exchange rate. An increase of the air exchange rate elevates the emission rate
due to the driving force of lower chamber concentrations at the higher air exchange
rates. The effect of relative humidity on PDCB emission was expected to be minor

(Nelms 1987). The emission rate of PDCB vapor within the test chamber should have
remained constant when the air concentration in the chamber reaches steady-state
conditions as long as chamber temperature, air exchange rate, and the surface area
of the PDCB crystals were held constant within a run.

SECTION 5
SAMPLING OF TEST CHAMBER AIR
A continuous sample of the test atmosphere was collected at the outlet of the
test chamber. A Gast two-cylinder vacuum pump pulled air from the test chamber via
Teflon tubing into parallel sets of sampling loops (0.25 and 1.0 ml_). These double-
loop sampling valves injected the contents of one loop while the other loop was being
flushed with test chamber air. Each rotation of the valve repeated the process with
the alternate loop (Figure 4). Both gas sampling valves were activated simultaneously
at 6-min intervals to inject the contents of the loop into a Varian 3700 gas chromato-
graph (GC) equipped with dual GC columns and detectors. The gas sampling valves
were rotated by motor-driven actuators which were activated by a relay device
controlled by a Compaq computer through an RS-232 interface.
Area count measurements were started just prior to running the check
standards and continued at 6-min intervals throughout the introduction of both
compounds into the test chamber, the air concentration buildup period, steady-state
equilibrium, and decay of both SF6 and PDCB (after removal of the sources). The
area count measurements ended when the air concentration of both compounds fell
below their respective LOD.

SECTION 6
ANALYSIS OF SULFUR HEXAFLUORIDE IN TEST CHAMBER AIR
The Varian gas chromatograph equipped with dual columns (A and B) and dual.
detectors was used to analyze air samples collected from the test chamber. SF6 was
analyzed on column A using an electron capture detector (ECD).
6.1 ANALYTICAL PROCEDURE
A 0.25-mL aliquot of test chamber air was automatically injected at 6-min
intervals into a Varian 3700 gas chromatograph (GC) using a Carle double-loop gas
sampling valve system.
The following instrument parameters were used for runs 1 through 6:
Instrument: Varian 3700 gas chromatograph
Detector: Electron capture (ECD)
Column (side A): Carbosieve S-ll (120/140 mesh);
1.2 m x 2 mm ID; glass
Carrier gas: Nitrogen
Carrier gas flow rate: 30 mL/min
Injector temperature: 250°C
Column temperature: 220°C
Detector temperature: 300°C
The following GC/ECD parameters were modified for runs 7 through 9 to
decrease the LOQ/LOD of the analytical method:
Column (side A): Carbosieve S-ll (120/140 mesh);
0.4 m x 2 mm ID, stainless steel
Carrier gas flow rate: 60 mL/min
Injector temperature: 230°C
Column temperature: 175°C
Detector temperature: 230°C
31
-------
The following instrument parameter was modified for runs 10 through 12 to
improve peak separation on the chromatograms:
Column (side A) temperature: 170°C
The Carle double-loop sampling valve injected the contents of one of two
matched loops (0.25 mL) while the other loop was being flushed with test chamber air.
Each rotation of the valve repeated the process with the alternate loop. The gas
sampling valve was rotated by a motor-driven actuator which was activated by a relay
device controlled by a Compaq computer through an RS-232 interface.
The analog output of the GC was processed by an analog-to-digital converter
based on a Wintek microcontrol system module interfaced with a Compaq micro-
computer. The microcomputer was running a Microsoft BASIC data logging and .
integration software program (ACE999, V09/22/88) modified specifically for this project
by MRI. The integration program was activated simultaneously with each sample
injection. The data system automatically quantified the chromatogram using preset
processing parameters. The area counts and retention times of each peak were
computed and printed on an Epson dot-matrix printer. The GC data output and
integration data were also saved to a hard disk. A Heath (Model SR 204) strip chart
recorder recorded the chromatogram and served as a backup to the data logger.
6.2 GC/ECD CALIBRATION PROCEDURE
The GC/ECD was calibrated over a range of 4 to 500 ppb using a series of SF6
standards prepared in Tedlar gas sampling bags. A neat concentration of SF6 was
prepared by flushing a 100-mL glass sampling bulb with SF6 from a Matheson lecture
bottle (Lot No. J81-0045-00) for runs 1 through 9, and from a Matheson compressed
gas cylinder (Lot No. J61-0231-A3) for runs 10 through 12 for approximately 4 min.
The stopcocks of the glass bulb were closed sequentially to avoid pressurizing the
SF6 gas. The glass bulb had a silicone septum midway down the length of the bulb.
Aliquots of the neat SF6 were extracted from the glass bulb using a gastight syringe to
prepare working standards of 10,000 and 2,000 ppm SF6 for runs 1 through 9 and of
10,000 and 1,667 ppm SF6 for the last three runs.
The series of seven SF6 standards were prepared for runs 1 through 9 by
diluting 1.0- and 0.5-mL aliquots of the 10,000-ppm SF6 standard, and 1.5-, 1.0-, 0.5-,
0.25- and 0.05-mL aliquots of the 2,000-ppm SF6 standard with high purity air to a
volume of 20 L to produce standards of 500, 250, 150, 100, 50, 25, and 5 ppb.
For the last three runs, the SF6 standards were prepared by diluting 1.0- and
0.5-mL aliquots of the 10,000-ppm SFe standard, and 1.5-, 1.0-, 0.5-, 0.25- and
0.05-mL aliquots of the 1,667-ppm SF6 standard with high purity air to a volume of
20 L to produce standards of 500, 250, 125, 83, 42, 21, and 4 ppb.
32
-------
The dilution volumes were metered using a calibrated dry gas meter (Singer
Co., MRI No. 9044) into clean, dry Tedlar gas sampling bags. The Tedlar bags
(Nutech Corp.) had Swagelok fittings that allow the injection of SF6 gas through
silicone septa using Hamilton gastight syringes.
Contamination of the Tedlar gas sampling bags was avoided by thoroughly
rinsing them with clean compressed air. The Tedlar bags were evacuated with a
vacuum pump, then filled with compressed air (Burnox UN1002). This process was
repeated three times. Each Tedlar bag that was used for the preparation of the
standard series or check standards was dedicated to one air concentration level.
Gastight syringes were rinsed with compressed air, heated to approximately 90°C, and
cooled to room temperature prior to use.
A blank sample was prepared with the standard series using the preparation
procedures specified above, except that no SF6 was injected into the Tedlar bag.
The eight Tedlar bags containing either one of the seven SF6 gas standards or
the blank were attached to a Teflon sampling line and introduced into the GC through
0.25-mL sampling loops using a Gast two-cylinder pump. The introduction of the SF8
standards into the GC was similar to that of the sampled air from the test chamber.
The only difference was the length of Teflon tubing the gas must pass through to
reach the sampling loops. Each standard was injected into the GC four times (two
injections per sampling loop) within 1 h after preparation.
A 100-ppb SFe check standard (runs 1 through 9) and an 83-ppb SF6 check
standard (runs 10 through 12), each prepared independently from the standard series,
were injected into the GC prior to each experimental run to monitor the accuracy and
precision of the system over the entire project; the responses for this check standard
were plotted on a control chart. If the results of the check standards were within the
control limit, the run was started; otherwise, the run was aborted and the GC/ECD was
then recalibrated with the standard series prior to the next run.
6.3 BACKGROUND INTERFERENCE DURING SF6 ANALYSIS
Before and after each experimental run, air within the test chamber was
analyzed by GC to determine potential background air concentrations. A peak of
unknown origin that was interfering with the SF6 measurements was detected by the
electron capture detector during runs 1 through 9. This unidentified peak appeared at
about the time when MRI switched from steam heating to air conditioning.
Attempts were made to identify the air contaminant but without success. The
chlorofluorocarbons in the air conditioning system were tested and were ruled out as
a possible source. The contaminant was most likely being drawn in the air
conditioning system from outdoors or from some location in the building and
distributed through the building via the air conditioning ducts.
33
-------
Modifications were made to the supply air plenum of the ACE Lab to filter the
air with activated charcoal, but the attempts were unsuccessful. The unknown
compound did not have an adequate affinity for activated charcoal and quickly broke
through the filtering system.
The appearance of the unknown peak on the chromatogram was quite different
from that of the SF6 peak. It was much wider at the base, which was in contrast to the
sharp, narrow appearance of the SF6 peak. The retention time of the unknown peak
on the Carbosieve S-ll column was approximately 21 min. The 6-min sampling interval
required of this experiment did not allow for the unknown peak to elute before
subsequent injections. The unknown peak from the first injection of air from the test
chamber into the GC would elute after the fourth injection, the unknown peak from the
second injection would elute after the fifth injection, and so on. The unknown peak
would therefore elute at the same time as an SF6 peak for each injection starting with
the fourth injection. Even though the unknown peak did not have the same retention
time as the SF6, it interfered with this peak due to the 6-min sampling interval.
Modifications to the GC parameters and GC columns could have eventually
solved this interference problem; however, it was decided for this set of experimental
runs that the data would be corrected by subtracting the contribution of the interfering
peak. The following criteria were used to determine the average background
interference and to subtract the background level from the SF6 air concentration data.
These criteria were developed by the Work Assignment Leader at MRI and the Co-
Work Assignment Managers at EPA with the concurrence of MRI and EPA Quality
Assurance Officers:
1. The average background air concentration in the test chamber was determined
for the measurements taken prior to each run. An equal number of back-
ground air concentration measurements were considered at the end of each
run. The averages of the two data sets were calculated. The run was
considered valid if the difference between these two averages was less than
2 ppb. All experimental runs included in this report met this criterion.
2. All background measurements described in criterion 1 were averaged. The run
was considered valid if the average background air concentration (expressed in
terms of equivalent SFe concentration) was less than 3 ppb and all measure-
ments were less than 5 ppb. All experimental runs included in this report
passed this criterion. This average background level was subtracted from each
SF6 concentration measurement made during the run.
3. The strip chart was monitored for each run to detect significant baseline drift or
a widening of the SF6 peak on the chromatogram, evidence that the interfering
background levels increased during the run. When the SF6 concentrations
were substantially above the detection limit, as they were throughout most of
the experiment, the interfering peak was not visible unless the concentration of
34
-------
the unknown compound increased to levels above 5 ppb. The appearance of
the chromatograms showed no evidence of this during any of the experimental
runs included in this report.
The observed interference levels were low compared to the levels of SF6 for all
experimental runs. Eight of the twelve experimental runs (3, 4, and 7 through 12) had
no detectable background interference. The mean background levels for the other
four runs (1, 2, 5, and 6), expressed in terms of equivalent SF6 concentration, ranged
from 0.73 ppb to 1.56 ppb.

SECTION 7
ANALYSIS OF p-DICHLOROBENZENE IN TEST CHAMBER AIR
The Varian 3700 gas chromatograph equipped with dual columns (A and B)
and dual detectors was used to analyze test chamber air. POCB was analyzed on
column B using a flame ionization detector (FID).
7.1 ANALYTICAL PROTOCOL
A 1.0-mL aliquot of test chamber air was automatically injected at 6-min
intervals into a Varian 3700 gas chromatograph (GC) using a Carle double-loop gas
sampling valve system.
The following instrument parameters were used for runs 1 through 6:
Instrument: Varian 3700 gas chromatograph
Detector: • Flame ionization detector (FID)
Column (side B): 1% SP-1000 on 60/80 Carbopack B;
0.6 m x 2 mm ID, stainless steel
Carrier gas: Nitrogen
Carrier gas flow rate: 30 mL/min
Injector temperature: 250°C
Column temperature: 220°C
Detector temperature: 300°C
The following GC/FID parameters were modified for runs 7 through 9 to
decrease the LOD/LOQ of the analytical procedure:
Column (side B): 1% SP-1000 on 60/80 Carbopack B;
0.4 m x 2 mm ID, stainless steel
Carrier gas flow rate: 104 mL/min
Injector temperature: 230°C
Column temperature: 175°C
Detector temperature: 230°C
37
-------
The following instrument parameter was modified in runs 10 through 12 to
improve peak separation on the chromatogram:
Column (side B) temperature: 170°C
The Carle double-loop sampling valve injected the content of one of two loops
(1.0 ml_), while the other loop was being flushed with test chamber air. Each rotation
of the valve repeated the process with the alternate loop. The gas sampling valve was
rotated by a motor-driven actuator which was activated by a relay device controlled by
a Compaq computer through an RS-232 interface.
The analog output of the GC was processed by an analog-to-digital converter
based on a Wintek microcontrol system module interfaced with a Compaq computer.
The computer was running a Microsoft BASIC data logging and integration software
program (ACE999, V09/22/88) which was modified specifically for this project by MRI.
The integration program was activated simultaneously with the sample injection. The
data system automatically quantified the chromatogram using preset processing
parameters. The area counts and retention times of each peak were computed and
printed on an Epson dot-matrix printer. The GC data output and integration data were
also saved to a hard disk drive. A Heath (Model SR 204) strip chart recorder
recorded the chromatograms and served as a backup to the data logger.
7.2 GC/FID CALIBRATION PROCEDURE
The GC/FID was calibrated using a series of seven standards prepared in
Tedlar gas-sampling bags. For experimental runs 1 through 6, a stock standard
solution of PDCB in hexane was prepared by weighing to the nearest 0.1 mg
approximately 5 g of PDCB (Aldrich Chemical, high purity, Lot No. 06205BV) which
was transferred to a 50-mL volumetric flask and diluted to the mark with hexane
(Burdick & Johnson, high purity, Lot No. AM062). The PDCB standards were
.prepared by diluting 0.200-, 0.100-, 0.050-, 0.020-, 0.010-, 0.005-, 0.00125-mL aliquots
of the stock standard mixture with 20 L of high purity air to obtain standard
concentrations of 153, 76, 38, 15, 8, 4, and 1 ppm PDCB in air.
For experimental runs 7 through 9, the concentration range of the PDCB
standard series was adjusted to reflect a lower limit of detection. A stock standard
solution of PDCB (Aldrich Chemical, high purity, Lot No. 06205BV) in hexane was
prepared by weighing to the nearest 0.1 mg approximately 2.2 g of PDCB (high purity)
which was transferred into 50-mL volumetric flask and diluted to the mark with hexane.
The PDCB standards were prepared by diluting 220-, 110-, 48-, 25-, 9-, 3-, and 1-/iL
aliquots of the stock standard mixture with 20 L of high purity air to obtain standards
of 74, 37, 16, 8, 3, 1, and 0.3 ppm PDCB in air.
For runs 10, 11, and 12, a stock standard solution of PDCB (Aldrich Chemical,
high purity, Lot No. 06205BV) in hexane (Burdick & Jackson, high purity, Lot
38
-------
No. AM062) was prepared by weighing to the nearest 0.1 mg approximately 2.2 g of
PDCB (high purity) which was transferred into 50-mL volumetric flask and diluted to
the mark with hexane. The PDCB standards were prepared by diluting 220-, 110-, 48-,
25-, 9-, 3-, and 1-/nL aliquots of the stock standard mixture with 20 L of high purity air
to produce standards of 74, 37, 16, 8, 3, 1, and 0.3 ppm.
The dilution volumes were metered using a calibrated dry gas meter (Singer
Co., MRI No. 9044) into clean, dry Tedlar gas-sampling bags. The Tedlar bags
(Nutech Corporation) have Swagelok fittings that allowed the injection of the test
compound through silicone septa using Hamilton gastight syringes.
Contamination of the Tedlar gas-sampling bags was avoided by thoroughly
rinsing them with clean compressed air. The Tedlar bags were evacuated with a
vacuum pump, then filled with compressed air (Burnox UN1002). This process was
repeated three times. Gastight syringes were rinsed with hexane and air dried prior to
use.
A blank was prepared with the standard series using the same preparation
procedures as specified above, except that no PDCB was injected into the Tedlar bag.
Each Tedlar bag containing either one of the standard series or blank sample
was attached to a sampling port and introduced into the gas chromatograph via the
sampling loops. The introduction of the standard series into the GC was similar to the
setup for the introduction of sampled air from the test chamber. The only difference
was the length of Teflon tubing the gas must pass through to reach the sampling
loops. Each standard was injected four times into the GC (two injections per sampling
loop) within 1 h after preparation. Each of the 1.0-mL sampling loops was calibrated
separately.
A check standard (38 ppm, runs 1 through 6; 16 ppm, runs 7 through 9; and
37 ppm, runs 10 through 12) were prepared independently from the standard series
and injected into the GC prior to each respective run to monitor the accuracy and
precision of the system over the entire project; the responses for this standard were
plotted on a control chart. If the results of the check standard were within the control
limits, the run was started; otherwise, the run was aborted and the GC/FID was then
recalibrated with the standard series prior to the following run.

SECTION 8
DATA ACQUISITION AND SAMPLE IDENTIFICATION
Data collection was performed using a computerized acquisition and
processing system. A flow chart of the system is presented in Figure 5.
8.1 DATA ACQUISITION SYSTEM
Temperature measurements were collected at 1-min intervals using two Type-K
thermocouples mounted on the east wall of the test chamber. The output of the
temperature sensors was processed by the Omega TAG 80 thermocouple-to-millivolt
converter. The output of the Omega TAG 80 was listed by the manufacturer as
1 mV/°F. Relative humidity and barometric pressure measurements were collected at
1-min intervals with the WEATHERtronics humidity sensor (5120-B) and the
WEATHERtronic 7105-A analog barometer. The analog output signals from the
sensors were conditioned by a WEATHERmeasure barometric pressure signal-
conditioning module (Model 1025). The Varian gas chromatograph outputs were
conditioned by optical isolators at 1 V full scale.
The analog outputs were assigned the following data logger channels:
• Channel 0—barometric pressure (WEATHERmeasure);
• Channel 1—relative humidity (WEATHERmeasure);
• Channel 2—room temperature (Omega, 1°F/mV input);
• Channel 3—exit temperature (Omega, 1°F/mV input);
• Channel 4—not used;
• Channel 5—Varian GC/ECD (1-V full-scale input);
• Channel 6—Varian GC/FID (1-V full-scale input); and
• Channel 7—not used.

-------
The conditioned analog signals were processed by an analog-to-digital
converter on a Wintek microcontrol system module in the data logger. The Wintek
6801 Micro Control System is a single-board computer incorporating the following
functions:
• Single-chip microprocessor (6801);
• 12-bit analog-to-digital (A/D) converter with true differential inputs;
• CMOS analog multiplexer expanding the A/D function to eight single-ended
inputs or four differential inputs;
• 8-brt D/A with current (4 to 20 mA) or voltage (1 to 5 V) outputs;
• 8 input/output (I/O) stations accommodating any mixture of optically isolated AC
outputs (120 V, 3 A), DC outputs (60 V, 3 A), or AC/DC inputs;
• On-board power supply requiring an external 12.6-V transformer; and
• An optically isolated 20-mA, half-duplex, current loop communications interface
for data transfer to a "host" processor (Compaq computer through an RS-232
port).
The analog-to-digital (A/D) subsystem of the Wintek card contains a reference
voltage source, integrator, comparator, and differential input circuitry. The A/D
process is the dual-slope type in which an unknown voltage is measured by timing the
interval required for the integrator output to cross the comparator threshold. The
conversion result is calculated from the reference integration time. Timing functions
are handled by the 6801 's programmable interval timer.
The 8-channel output of the Wintek Micro Control Module was transmitted at a
baud rate of 1200 bits/s to a Compaq portable microcomputer via the RS-232 port.
The microcomputer was running the ACE999 data-logging program (V09/22/88)
written and compiled in Microsoft BASIC by MRI staff. The program required an
MS-DOS computer equipped with an RS-232 port, CGA compatible display/and a
dot-matrix printer connected to a parallel port. The output of the program produced
four types of data files: a sensor calibration data file, a GC calibration data file, a
multichannel data-logger output file, and GC data files (one for each injection into the
GC). The sensor calibration data file contained the zero and span settings for the
temperature, relative humidity, and barometric pressure instruments. The GC
calibration file contained the data for a single-point calibration for both GC channels.
This single-point calibration was not used for this project. The data-logger output file
contained a data table listing the barometric pressure, relative humidity, the room
temperature, exit temperature, and the clock time at 1-min intervals. The GC data files
with unique and sequentially numbered file names contained the output of both GC
43
-------
detectors including peak identifiers, retention times, area counts, and clock times at
6-min intervals.
8.2 DATA PROCESSING
The environmental and GC data files stored on the Compaq's hard disk were
converted into ASCII format by the ACE999 converter program and saved onto floppy
disks. These ASCII data files were transported to an IBM 80386 computer and
imported into a Lotus 1-2-3 spreadsheet program (version 2.01 for data from runs 1
through 9 and version 3.1 for runs 10 through 12). The temperature, barometric
pressure, and relative humidity data were corrected in the spreadsheet using the
offsets determined by the check calibration conducted prior to each run with NIST-
traceable thermometers, psychrometer, and barometer. The environmental data
tables presented in this report were produced directly from these Lotus spreadsheets
using the Allways printer utility program linked to the Lotus 1-2-3 program.
The GC data files were imported into Lotus 1-2-3 to manipulate the data into
standardized columns and rows. These data sets were saved to a floppy disk in
ASCII format, transported to an IBM PC running SmarTerm terminal emulation
software, and uploaded to a DEC PDP-11723 Plus minicomputer. The DEC computer,
running IBM 3780 terminal emulation software, transmitted the ASCII data files via a
modem to an IBM 4381 mainframe computer located at the University of Missouri at
Columbia. Analysis of the data was accomplished using Statistical Analysis System
(SAS) software, SAS Institute, Gary, North Carolina. The output of the statistical
analyses was transmitted from the IBM mainframe back to the DEC PDC-11/23+ via
modem. The IBM PC running SmarTerm captured the data from the DEC and stored
them in ASCII format onto floppy disks. These ASCII data files were then transported
back to the IBM 80386 computer and imported into Lotus 1-2-3. All tables presented
in this report were produced directly from these Lotus spreadsheets using the Allways
printer utility. The graphs were produced directly from the Lotus spreadsheets using
Lotus Printgraph utility and Lotus Freelance software.
8.3 SAMPLE IDENTIFICATION
The GC data files were saved to the hard disk under unique file names. All
computer files were stamped with the date and time generated by the computer's
internal clock. The area counts of detected peaks were also printed on an Epson
FX-85 printer along with the file name. These file numbers were manually transcribed
onto the GC output on the strip chart recorder so that integration data could be linked
to their respective chromatograms. The date and time stamp on the environmental
data linked these data to GC data output.
Strip charts, magnetic disk, and so forth, were labeled with a format identifier,
project number, date, the ID(s) of the instrument, and the name of the person
responsible for the data.

SECTION 9
DATA ANALYSIS APPROACH
9.1 ANALYSIS OF CALIBRATION DATA
The relationship between area counts and concentration levels was quantitated
by means of regression analysis for SF6 and PDCB. The calibration data from each
gas sampling loop (A and B) were analyzed separately in each case. First- and
second-order linear models were fitted to the data and evaluated for best fit.
Residuals and error estimates from each model were examined, and statistical
assumptions were checked. A decision as to the best model (i.e., calibration
equation) in each case was made, and that model was used subsequently in the
analysis of experimental data from the twelve test runs.
9.2 CALCULATION OF SF6 AND PDCB CONCENTRATIONS
For each run, SF6 and PDCB area counts were obtained over a period of time.
Using the calibration equation for each compound and each loop separately, the
concentrations at time t were estimated by inverse regression from the area counts at
time t as follows:
Cone, = -B/2C - ^(B/2C)2 - (A-Yt)/C
where A, B, and C are the coefficients from the second-order calibration equation
[area counts = A + B x Cone + C x Cone2] and Y, is the area count measured at
time t; or
Conct = (Yt-A)/B
where A and B are the coefficients from the first-order calibration equation
[area counts = A + B x Cone].
45
-------
9.3 BACKGROUND CORRECTION OF SF6 CONCENTRATIONS (RUNS 1,2, 5,
AND 6)
For the four of the 12 experimental runs (runs 1, 2, 5, and 6) in which
interference of an unidentified compound with SF6 occurred (see discussion in
Section 6.3), SF6 concentrations were corrected for background concentrations of that
compound found in the test chamber. The approach for background correction of all
SF6 concentration calculations is explained next. The correction was done for each
run separately.
Background data collected before the source of SF6 was inserted into the test
chamber were identified ("before" data). The concentration levels of SF6
corresponding to these data points were averaged. SF6 concentration levels for an
equal number of data points at the end of the run ("after" data) were averaged as well.
Next, the two averages were compared. If the two means differed by less than 2 ppb
and if no calculated concentration exceeded 5 ppb, then the average across the
"before" and "after" SF6 background concentrations was computed. If this average did
not exceed 3 ppb, then it was subtracted from all SF6 concentration for that specific
run.
9.4 DATA BASE SELECTION FOR MODELING
The data used in modeling the decay of SF6 and PDCB concentrations over
time were restricted to the data starting with the first data point obtained just prior to
the withdrawal of the gas sources from the test chamber (see data in Appendix G).
Further, the data were truncated at the end of each run. Data following the first
occurrence when the SF6 concentration fell below 5 ppb were discarded from the
statistical analysis. A 1-ppm cutoff for runs 1 through 6 and a 0.3-ppm cutoff for runs
7 through 12 were used for PDCB concentrations. These figures correspond to the
limits of quantitation for the two compounds.
9.5 SF6 AND PDCB CONCENTRATION DECAY MODELING
Data from each run were analyzed separately. A series of decay models were
fitted to the SF6 and PDCB concentration data over time. These models included first-
and second-order exponential decay models for both compounds. A segmented
model, consisting of a second-order exponential decay curve followed by a first-order
linear equation, was also fitted to the PDCB concentration. Each model was forced
through C0> the concentration calculated at time t = 0 when the source was removed.
The equations considered take the general forms:
First-order exponential decay: Cone = C0 exp(-At) (8)
Second-order exponential decay Cone = C0 exp(-Bt + Ct2) (9)
46
-------
Segmented second-order exponential decay and first-order linear:
r Cone = C0 exp(-Dt + Et2) if t < T, the time of model transition
1 Cone = F + Gt otherwise (10)
where A, B, C, D, E, F, G, and T are model parameters (coefficients) to be estimated
from the data. The coefficient A in Eq. 8, obtained for SF6, provides an estimate of the
air exchange rate within the test chamber. All modeling was performed using SAS, a
statistical software package for IBM mainframe computers. The specific procedures
used were the linear regression and nonlinear regression procedures (PROC REG and
PROC NLIN, respectively).
To model Eqs. 8 or 9 above, the concentrations were first log-transformed and
the regression parameters estimated on the log-scale. The correspondence between
the parameter estimates on the original scale, that is, untransformed, and those on the
log-scale is demonstrated below for Eq. 9.
To estimate the two parameters B and C, divide both sides of the equation by
C0 (a constant for each run and each compound) and then take the natural logarithm
on each side of the equation:
log(Conc/C0) = Iog[exp(-Bt + Ct2)]
or
log(Conc) - log(C0) = -Bt + Ct2
Thus, to use a standard linear regression analysis procedure, the response variable to
be modeled versus time is [log(conc) - log(C0)], selecting the no-intercept model
option. The regression coefficients B and C are directly obtained from that regression
analysis.
For each model found to be best fitting a particular set of data, upper and
lower 95% confidence limits to the fitted decay line were also computed.
9.6 SINK EFFECT ESTIMATION
For each individual run, the sink effect was estimated as a function of time, the
initial PDCB concentration at time t = 0 (C0), the air exchange rate (A) of SF6 during
the same run, and the parameter estimates (B and C or D, E, F, G, and T) of the
PDCB decay function.
If Eq. 9 above best described the PDCB concentration decay curve, then the
sink effect, at time t, expressed in ppm, was estimated by the following difference:
Estimated sink effect = C0 exp(-Bt + Ct2) - C0 exp(-At)
47
-------
If Eq. 10 best described the PDCB concentration decay curve, then the sink
effect, at time t, was estimated as follows:
r Estimated sink effect = C0 exp(-Dt + Et2) - C0 exp(-At) if t < T
I Estimated sink effect = F + Gt - C0 exp(-At) otherwise
These equations describe concentration versus time relationships of various
shapes. To standardize these equations with respect to their air exchange rates, let X
be the product of air exchange rate and time (At). Then, substituting t = X/A into the
two equations above, the two sets of equations for sink effect will become:
Estimated sink effect = C0 exp[-(B/A)X + (C/A^X2] - C0 exp(-X)
or
( Estimated sink effect = C0 exp[-(D/A)X + (E/A^X2] - C0 exp(-X) if X < AT
I Estimated sink effect = F + (G/A)X - C0 exp(-X) otherwise
.These relationships of sink effects, in ppm, versus number of air exchanges,
were plotted for each experimental run.

SECTION 10
RESULTS
10.1 ENVIRONMENTAL DATA
Temperature, relative humidity, and barometric pressure within the ACE
Laboratory test chamber were monitored at 1 -min intervals throughout each of the
runs. The temperature was set between 72° and 76°F and was controlled within
±1.8°F (i.e., temperature range not to exceed 3.6°F). Temperature control within the
test chamber met the performance objective specified in the QAPj'P for all 12 runs.
The humidity within the test chamber was set between 35% and 55% and
controlled to within ±10% (i.e., % humidity range not to exceed 20%). The humidity
control met the performance objective set in the QAPjP. Barometric pressure was
monitored but not controlled. A summary of the environmental data for all 12 runs is
presented in Table 3.
10.2 PDCB EMISSION RATES
The emission rates of PDCB were calculated by subtracting the final weight
from the initial weight of the crystals and dividing this term by the duration of each run.
The emission rates of PDCB are summarized in Table 4.
10.3 CALIBRATION RESULTS
The following sections present the results obtained from runs 1 through 10 and
run 12 data. As mentioned earlier, due to anomalies in run 11 data, all results
pertaining to that run are suspect and have been moved to Appendix H.
10.3.1 SFfl Calibration Results
The GC/ECD was calibrated using a series of SF6 standards. One set of
calibrations was performed prior to runs 1 through 6. Another set was performed
prior to runs 7 through 9. Separate calibrations were performed prior to runs 10 and
12. Area counts from duplicate injections of eight concentrations, including a blank,
were obtained for each of the two loops, A and B. Thus a total of 16 pairs of data
were available for each run. The data were analyzed separately for the two loops and
for each run.

A quadratic equation best described the relationship between area counts and
SFe concentrations for runs 1 through 9 for either loop. However, a first-order
equation best described the relationship between area counts and SF6 spike levels for
runs 10 and 12. A 5% significance level was selected as the criterion for inclusion of a
quadratic term. Overall, R-squared values range from 99.64% to 99.99%. The data
and the regression results for each loop are presented in Tables C-1 through C-4 in
Appendix C. Measured and predicted area counts are plotted versus concentration
levels in Figures C-1 through C-4 in Appendix C.
The following SF6 calibration equations were used in all subsequent data
analyses when calculating concentrations from area counts:
Runs 1 through 6:
Loop A: SF6 Area Counts = 1,861 + 2,567 Cone. - 0.86 Cone.2
Loop B: SF6 Area Counts = 2,008 + 2,523 Cone. - 0.79 Cone.2
Runs 7, 8, and 9:
Loop A: SF6 Area Counts = -1,533 + 1,429 Cone. - 0.26 Cone.2
Loop B: SF6 Area Counts = -1,298 + 1,428 Cone. - 0.23 Cone.2
Run 10:

Loop B: SF6 Area Counts = -7,187 + 2,008 Cone.
Run 12:
Loop A: SF6 Area Counts = -5,583 + 1,281 Cone.
Loop B: SF6 Area Counts = -4,744 + 1,258 Cone.
10.3.2 PDCB Calibration Results
The GC/FID was calibrated using a series of PDCB standards. One set of
calibrations was performed prior to runs 1 through 6. Another set was performed
prior to runs 7 through 9. Separate calibrations were performed prior to runs 10 and
12. Area counts from duplicate injections of eight concentrations, including a blank,
were obtained for each of the two loops A and B. Thus a total of 16 pairs of data
were available for each loop. The data were analyzed separately for the two loops
and for each run.
53
-------
Depending on the run and the loop (A or B), a quadratic or a linear equation
best described the relationship between area counts and POCB spike levels. Overall,
R-squared values ranged from 99.84% to 99.99%. A 5% significance level was
selected as the criterion for inclusion of a quadratic term. The data and the
regression results for each loop are presented in Tables C-5 through C-8 in
Appendix C. Measured and predicted area counts are plotted versus concentration
levels in Figures C-5 through C-8 in Appendix C.
The following PDCB calibration equations were used in all subsequent data
analyses when calculating concentrations from area counts:
Runs 1 through 6:
Loop A: PDCB Area Counts = -1,893 + 3,695 Cone. - 2.41 Cone.2
Loop B: PDCB Area Counts = -1,415 + 3,471 Cone. - 1.45 Cone.2
Runs 7, 8, and 9:
Loop A: PDCB Area Counts = 242 + 7,333 Cone.
Loop B: PDCB Area Counts = 1,223 + 7,409 Cone.
Run 10:
Loop A: PDCB Area Count = 6,416 + 23,210 Cone.
Loop B: PDCB Area Counts = 951 + 23,979 Cone. - 19.89 Cone.2
Run 12:
Loop A: PDCB Area Counts = -2,329 + 26,021 Cone. - 35.89 Cone.2
Loop B: PDCB Area Counts = -2,560 + 26,155 Cone. - 45.22 Cone.2
10.4 SF6 DECAY RESULTS
SF6 concentrations were calculated from the area counts by inverse regression
using the SF6 calibration equations for loops A and B, as appropriate. Next, for runs
1, 2, 5 and 6, the calculated concentration levels were corrected for background
interference (see Section 6.3) by subtracting the following mean background
concentrations from the calculated concentrations:
Run 1: mean background = 1.56 ppb
Run 2: mean background = 0.73 ppb
54
-------
Run 5: mean background = 1.32 ppb
Run 6: mean background = 1.00 ppb
The average background was 0 ppb (i.e., no interference was observed) for all other
runs. Calculated SF6 concentration levels are plotted versus time for the entire length
of each run in Figures D-1 through D-11 in Appendix D.
For all 11 of the experimental runs reported here, a first-order exponential
decay model was chosen to best fit the data. A second-order model was also fitted to
the data. However, for all practical purposes, the first-order decay model (Eq. 8,
Section 9), yielding R-squared values of between 98.93% and 99.99% for all 11 runs,
was selected without significant loss of fit. The regression results for all SF6 runs are
shown in Table 5.
The first column in Table 5 indicates the run number followed by the sample
size in each run. Each data point corresponds to a time point at which an area count
was measured. Since measurements were taken every 6 min, a sample size of 44, for
example, would indicate that the test ran for 4.4 h from the start of the decay. The
next two columns, R-squared and RMSE, are measures of fit of the model to the data.
R-squared is the proportion of variance in the data explained by the model, and RMSE
is the root mean squared error, an estimate of the standard deviation of the error term
of the selected model. The last two columns list the coefficients of each decay model:
C0, the SF6 concentration at time t = 0, that is, the Y-intercept, and the air exchange
rate, A.
Calculated and predicted SF6 concentrations, along with the lower and upper
95% confidence limits to the regression line, are plotted versus time in Figures E-1
through E-11 in Appendix E.
10.5 PDCB DECAY RESULTS
PDCB concentrations were calculated from the measured area counts by
inverse regression using the PDCB calibration equations for loops A and B, as
appropriate. These concentrations were not corrected as were SF6 concentrations
since no interference with PDCB was observed.
Calculated PDCB concentration levels are plotted versus time for the entire
length of each run in Figures D-12 through D-22 in Appendix D.
A second-order exponential decay function (Eq. 9 in Section 9) was found to
best fit the three sets of data obtained from the runs conducted in the empty test
chamber. For each run, the regression parameters B and C in Eq. 9 were estimated.
Each regression line was forced through C0, the PDCB concentration at time t = 0.
Regression parameters, B and C, and the two measures of fit, R-squared and RMSE,
are summarized in Table 6 for runs 1, 2, and 3.

A segmented second-order exponential decay followed by a first-order linear
function (Eq. 10 in Section 9) was found to best fit the data obtained from the
remaining 8 runs. This can be explained by the fact that PDCB concentrations were
trailing at levels well above 1 ppm (runs 4, 5, and 6) and above 0.3 ppm (runs 7
through 10 and 12) for a relatively long period of time. For each run, the time, T, at
which the model switches from one form to another is estimated by the nonlinear
regression procedure along with the other regression parameters, D and E, the linear
and quadratic coefficients of the exponential decay form, and F and G, the regression
coefficients of the straight line form taken after time T. Each regression line was
forced through C0, the PDCB concentration at time t = 0.
Regression parameters D, E, F, G and time T, and RMSE, a measure of fit of
the model to the data, are summarized in Table 7. An R-squared value is not available
from this form of the model whose parameters were estimated by nonlinear regression
analysis. However, an estimate of fit, RMSE, the root mean squared error, is given for
each run.
Calculated and predicted PDCB concentrations, along with the lower and upper
95% confidence limits to the regression line, are plotted versus time in Figures E-12
through E-22 in Appendix E.
10.6 SINK EFFECT ESTIMATION
The sink effect for each run was estimated as a function of time by taking the
difference, at each time point, between the PDCB level estimated by the respective
decay model and the PDCB level obtained using the corresponding SF6 air exchange
rate. These differences were then standardized by expressing them as a function of
air exchanges rather than time (see discussion in Section 9.6). Estimated sink effects

-------
for the four sets of runs (i.e., the four test chamber configurations) are plotted against
the number of air exchanges in Figures 6 through 9. These figures show the number
of air exchanges that would be needed to offset the sink effects measured for each
experimental condition. The PDCB concentration (y-axis) is the difference between the
concentrations estimated by the sink model and that given by the simple decay
model.
The maximum differences between PDCB air concentrations predicted from the
models fitted to the calculated concentrations and those of the air concentrations
predicted from Eq. 3 are as follows:
Empty test chamber: 0.9 ppm
Test chamber with carpet: 1.6 ppm
Test chamber with carpet and drapes: 7.9 ppm
Test chamber with carpet and bed: 2.6 ppm
The PDCB decay models from each run were also used to predict the number
of air exchanges needed to reduce PDCB air concentrations from a high to a low
level. As an example, the models fitted to the PDCB data in the presence of sinks
(Section 9) and the model described by Eq. 3 (Section 1) were used to calculate the
number of air exchanges required to reduce the air concentration of PDCB from
14 ppm to 2 ppm (Table 8). Under the assumption of no sink effect (Eq. 3), it would
require 1.95 air exchanges to reduce the PDCB concentration from 14 to 2 ppm,
regardless of chamber configuration. (The number 1.95 is obtained by solving the
equation, 2 = 146'*, for At.)
The average number of air exchanges necessary to reduce the PDCB air
concentration within the empty test chamber from 14 to 2 ppm as calculated from the
decay models is 2.50. It would require an average of 3.21 for the test chamber with
carpeting, 6.64 for the test chamber with carpeting and drapes, and 3.75 for the test
chamber with carpeting and a bed.

QUALITY ASSURANCE
11.1 ACCURACY
Check standards of both SF6 and PDCB were injected four times (twice per
sampling loop) into the GC after calibration and before each experimental run to
monitor the accuracy and precision of the system over the entire project.
For each loop and each compound, area counts were predicted using the
appropriate calibration equation as determined in Section 10.3. Percent accuracy
(A%) and range percent (R%) were computed as determined in the Quality Assurance
Project Plan. Accuracy and precision data are presented in Table F-1 (SF6) and
Table F-2 (PDCB) in Appendix F.
The accuracy determinations range from 85.1% to 105.6% for SF6 and from
87.6% to 113.6% for PDCB. Accuracy objectives (in terms of percent relative error) for
SF6 were set between 85% and 115%. For runs 1 through 6, the accuracy objective
for PDCB was set between 75% and 125%. For the remaining runs the accuracy
objective was set between 85% and 115%. These objectives were achieved.
Control charts plotting accuracy results with their upper and lower control limits
are shown in Figure 10 for SF6 and in Figure 11 for PDCB.
11.2 PRECISION
The precision determinations, expressed as range percent, vary between 0.05%
and 3.01 % for SF6 and between 0.08% and 6.94% for PDCB. Control limits for
precision were set at below 15% for both PDCB and SF6. These objectives were
achieved.
Control charts plotting precision results with their upper and lower control limits
are shown in Figure 12 for SF6 and in Figure 13 for PDCB.

11.3 PERFORMANCE AUDIT SAMPLE REPORT
A performance audit sample (PAS) was submitted by the Quality Assurance
Manager (QAM) prior to run 5. This was a deviation from the QAPj'P, which specified
that the PAS was to be submitted prior to run 1. The performance audit sample was
analyzed after the GC/FID and GC/ECD systems were calibrated with the full standard
series for each compound. The PAS was prepared in air using p-dichlorobenzene
(PDCB, Lot No. 06205BV) from Aldrich Chemical Company, Inc., and sulfur
hexafluoride (SF6, Lot No. J81-0045-00) from Matheson Gas Products. The PDCB
standard for the PAS was prepared by the QAM from neat material diluted in hexane
(Burdick & Jackson, Lot No. AM062) and injected into a Tedlar bag containing 20 L of
air to give a final concentration of 29 ppm of PDCB. The SF6 (internal standard) used
for the PAS was prepared by the project staff due to the complexities of gas standard
preparation. SF6 was injected by the QAM into the Tedlar bag containing the PDCB at
a concentration of 100 ppm.
The results of the PAS were 80.0% accuracy for the PDCB and 90.4% accuracy
for the SF6. These results are within the data quality objectives established in the
QAPjP.
A performance audit sample report was submitted by the QAM prior to run 11.
A performance audit sample containing SF6 and PDCB in air was prepared in a Tedlar
bag by the QAM and submitted to the WAL The performance audit sample was
analyzed prior to run 11 after the GC/FID and GC/ECD systems were calibrated with
the full standard series for each compound. Independently prepared check standards
of SF6 (83 ppb) and PDCB (37 ppm) were also analyzed immediately after running the
standard series and again immediately prior to the start of run 11. The accuracy and
precision of the check standard were found to be within the performance objectives of
the project. After all the necessary QC samples (standards, check standards, blank,
and background samples) were run and determined to be within the performance
^objectives, run 11 was started.
After the data were collected for run 11, the results of the performance audit
sample were calculated from the standard curve. The results of the analysis were
then submitted to the QAM. The air concentration of each analyte in the audit sample,
as measured by the GC system, was compared with the calculated air concentration
of the audit sample as prepared by the QAM. The results (in units of percent of air
concentration found versus actual) were 88.7% and 73.6% for PDCB and SF6, respec-
tively. The PDCB results were within the range specified in the QAPjP (85% to 115%);
however, the SF6 was not within this range. This problem, along with instrument
problems described in detail in Appendix H, make the data set from run 11
questionable. Run 11 data were segregated from the data base and are presented in
Appendix H.
68
-------
The results of the performance audit sample were immediately reported to the
acting MRI project manager. The acting project manager, WAL, and QAM decided
that the GC system should be recalibrated and a new performance audit sample be
submitted and analyzed prior to the next experimental run.
Prior to run 12, a second performance audit sample was prepared by the
department Quality Assurance Coordinator (QAC). The sample was analyzed by the
WAL after the GC/FID and GC/ECD systems were calibrated with the full standard
series for each compound. The results were 100.3% for PDCB and 96.9% for SF6.
These results were well within the acceptable criteria.
11.4 DEVIATIONS FROM THE QAPjP
The QAPjP, revisions 2 and 3, specified that a performance audit sample was to
be prepared and submitted by the QAM for GC analysis during the first experimental
run; however, this was not done until prior to run 5. The main cause of this deviation
was the WAL's failure to request the submission of the PAS in a timely fashion.
On August 21, 1991, the MRI WAL informed the EPA WAM of an inadvertent
deviation from the QAPjP regarding the preparation of the SF6 calibration standard
series. The problem was investigated by the WAL and immediate corrective action
was taken.
As stated in the QAPjP, volumetric glass bulbs are used to prepare working
standards of 10,000 and 2,000 ppm SF6 from which a series of seven SF6 standards
are prepared in Tedlar bags. A duplicate set of working standards were also
independently prepared for use in making the check standards. The 2,000-ppm
working standards were prepared by injecting a 1-mL aliquot of neat SF6 gas into a
glass bulb with an assumed volume of 500 mL The 10,000-ppm standards were
prepared by injecting 2.5 mL of neat SF6 into a 250-mL glass bulb. The five lower
concentration SF6 standards in air are prepared from the 2,000-ppm working
standard, and the two upper standards are prepared using the 10,000-ppm working
standard. A midconcentration check standard is independently prepared from a
duplicate 2,000-ppm working standard. When the first standard series was run on the
GC, it became very apparent from the calibration curve that the concentrations of
either the five lower standards or the two upper standards were not the correct
concentration.
The WAL investigated the problem by reviewing the standard preparation
procedure. It was discovered that the volume of the larger glass bulbs used to
prepare the 2,000-ppm working standards was not clearly marked. The volume of
both glass bulbs were checked by the WAL using water and a gravimetric procedure.
The larger glass bulbs were found to be 600 mL and not 500 mL The actual SF6
concentration of the working standard was recalculated to be 1,667 ppm. In the
interest of time, the WAL made the decision to recalculate the entire standard series.
69
-------
The 1,667-ppm working standard was used for experimental run nos. 10, 11, and 12.
The EPA WAM was informed of this inadvertent deviation from the QAPjP by MRI via
telephone on August 21. On September 8, this verbal communication was followed
up by a written notification.
11.5 QUALITY ASSURANCE REPORT
A system check was conducted by the QAC during the pilot study to ensure
that the protocols and procedure were in place for the study as required by the
QAPjP.
System audits were conducted by the QAM at the end of run 3 through the
completion of run 4, during run 7, and at the end of run 10 through the completion of
run 11. During these audits the facilities and equipment were found to be as
described in the QAPjP. The project personnel were found to be knowledgeable of
the purpose and operations of the study and the use of the equipment. At the time of
the system audit, a limited data audit was also performed. During this audit, the data
were found to be traceable and consistent with the requirements of the QAPjP.
The draft report and data were reviewed by the acting QAM. The data transfers
and manipulations were reviewed along with the process of the transfers and data
checks. Other data reviewed were the GC calibrations and the data associated with
the addition of PDCB and SF6 to the test chamber. The data were found to be
consistent with the requirements established in the QAPjP and in agreement with the
data in the report. During the systems audit, the systems and requirements
established by the QAPjP were followed except for the schedule for submital of the
PAS.

SECTION 12
CONCLUSIONS
The objectives of this project were two-fold. First, a series of experimental tests •
in a room-size test chamber were performed to assess the sink-effect characteristics
of an indoor air pollutant in the presence of selected surfaces and building materials.
Next, the significance of these sink effects to existing predictive mathematical models
of indoor air pollutants was determined. This report presents the data from 12
experimental runs using a chemical, p-dichlorobenzene, in a room-size test chamber
with interior surfaces covered with gypsum wallboard. Triplicate experimental runs
were conducted in the test chamber using four configurations: empty test chamber;
test chamber outfitted with wall-to-wall carpet; test chamber with carpet and drapes;
and test chamber with carpet and a full-size bed with a comforter.
Sulfur hexafluoride was used to determine the air exchange rates of each run
within the chamber and to demonstrate the actual decay of the chemical in the
absence of sink effects under the environmental conditions set for each run. The
empirical decay curve for SF6, obtained from fitting SF6 concentrations over time after
the source of the gas was withdrawn from the chamber, coincided with the theoretical
decay curve predicted by the simple dilution model (Eq. 3 in Section 1). These results
obtained from the modeling suggest that SF6 gas was a suitable reference compound
to demonstrate the behavior of the chemical in the test chamber in the absence of
sink effects under the environmental conditions selected for these experiments.
Sink effects were observed when the estimated rate of decay of PDCB deviated
from the rate predicted by Eq. 3, using the air exchange rate determined by SF6. This
effect can be explained by the fact that a source other than C0, the concentration of
PDCB in the air at the beginning of the decay period (removal of the source, t = 0), is
contributing to PDCB concentration (C,) in the outlet air throughout the time of decay.
This results in measured PDCB air concentrations that exceed the air concentrations
predicted by Eq. 3, that is, in the absence of sink effects. The sink effect was found in
all 12 experimental runs. The most likely source was PDCB adsorbed to chamber
surfaces during the experiments, with PDCB subsequently desorbing and reentering
the air. The magnitude of the sink effect was influenced by furnishings added to the
chamber.
In the presence of sinks, a higher number of air exchanges was required to
reduce PDCB air concentrations within the test chamber to background levels after the
71
-------
source of the contaminant was withdrawn. As an example, the models fitted to the
PDCB data in the presence of sinks and the model described by Eq. 3 were used to
calculate the number of air exchanges required to reduce the air concentration of
PDCB from 14 ppm to 2 ppm. Under the assumption of no sink effect, it would
require 1.95 air exchanges to reduce the PDCB concentration from 14 to 2 ppm.
However, the average number of air exchanges calculated from the models for the
empty test chamber was 2.50. The average number of air exchanges required in the
carpeted chamber was calculated to be 3.27. The average number of air exchanges
required in the chamber with carpet and drapes was 6.64, while that for the test
chamber with carpet and a bed was 3.75. Thus, the first-order decay model (Eq. 3)
would significantly underestimate the number of air exchanges necessary to reduce air
concentrations to background levels. As shown in this study, the sorption of PDCB
onto chamber surfaces and its subsequent desorption was significant relative to the
PDCB levels in the room air. Therefore, sink effect terms should be incorporated into
predictive exposure models. Additional modeling of the data base generated during
this study should be undertaken. Fitting other models to these data, based on some
type of equilibrium adsorption phenomenon or other physically-based concept, should
be attempted.

SECTION 1
STUDY OBJECTIVES
The objectives of this project are to perform a series of experimental tests in a
room-size test chamber to assess the sorption and desorption characteristics of
indoor air pollutants in the presence of selected surfaces and building materials and to
determine the significance of these sink effects to existing predictive mathematical
models of indoor air pollutants. Because of the absence of any known previous work
of this nature and the complexity of the project, a pilot study was conducted to
develop the procedures and to determine the optimum instrument parameters.

SECTION 2
PILOT STUDY DESIGN
A pilot study was conducted in a room-size test chamber at MRI's Air
Consumer Exposure (ACE) Laboratory that simulated a residential room where
household consumer products would be used. Experiments were conducted to '.
determined whether SF6 conformed to the simple-dilution model (QAPP, Section 1).
and to determine whether SF6 gas is a suitable reference compound for the study.
SF6 is a colorless, odorless, nontoxic, and nonflammable gas. It is completely stable
in the presence of most materials to temperatures of about 400°F, and has shown no
breakdown or reaction in quartz at 900°F. SF6 is slightly soluble in water and oil
(Compressed Gas Association, 1966). It is readily liquified and is shipped in steel
cylinders as a liquified gas .under its own vapor pressure of about 320 psig at 70°F.
This stable, inert gas has been used extensively as a tracer for ventilation studies and
for determinations of air exchange rates in air chamber studies. p-Dichlorobenzene
was chosen as the organic compound to be tested in the chamber.
An experiment was conducted to measure the decay rate of SF6 and PDCB in
dynamic tests in the test chamber under stable environmental conditions (air exchange
rate, temperature, and relative humidity). PDCB vapor and SF6 gas were released
simultaneously into the test chamber at constant emission rates. The air concentra-
tions of SF6 and PDCB were measured at 7.5-min intervals. The air concentrations
were allowed to reach equilibrium within the chamber. After maintaining the air
concentrations at a constant level for approximately 4 h, the sources of the PDCB and
SF6 were removed.
The air concentrations of PDCB and SF6 measured immediately prior to the
removal of the source at t=0 were the initial concentrations (C0 and C,, respectively) in
the decay model (QAPP, Eq. 3), which represents the decay caused solely by dilution.
The measured air concentrations of PDCB and SF6 were plotted against time, and
curves were fitted to the data. The empirical decay curve for each chemical was
compared to the theoretical decay curve generated by Eq. 3 using the air exchange
rate (A) calculated by the linear regression of the log-transformed SF6 air
concentration data vs. time.
An additional experiment was conducted to measure the decay rate of the SF6
reference gas in the test chamber using the same configuration as the previous run
with the addition of wall-to-wall carpeting on the floor. SF6 was injected at controlled
A-5
-------
rates into the chamber. After steady-state equilibrium was reached and maintained for
approximately 4 h, the injection of SF6 gas into the test chamber was stopped. The
measured air concentration of SF6 was plotted against time, and a curve was fitted to
the data. The empirical decay curve for SF6 was compared to the theoretical decay
curve generated by Eq. 3.

ACE LAB TEST CHAMBER FACILITIES
This study was conducted in a room-size test chamber located in MRI's ACE
Laboratory (Room no. 214/216-E). The volume of the test chamber was set at 1,261
cu ft. The floor dimensions of the chamber were 14 ft x 11.4 ft. The ceiling height
was 7.9 ft.
All wall, floor, and ceiling surfaces were covered with gypsum drywalI except for
the door at the entrance to the chamber (3.5 in x 40.5 in, wood), an observation
window (30 in x 30 in, glass), an air inlet port (12 in x 12 in), and an air outlet port
(12 in x 12 in). The wallboards were sealed with ready-mix joint compound (Magnum
Products R-100 and R-200 vinyl formulation); and all interior surfaces were painted
with one coat of interior PVA Latex primer sealer (DeVoe no. 55201-50) and one coat
of semigloss interior Latex (DeVoe no. 52549-50).
An additional test run was conducted using the same configuration as described
above with the addition of wall-to-wall carpeting on the floor. The carpet pile is 100%
polyester (Burlington Monticello M3776) and was purchased on October 14, 1988 from
a local retail outlet. The carpeting was unrolled over a concrete floor and allowed to
air out until it was installed in the test chamber. No pad was installed underneath the
carpet.

SECTION 4
TEST CHAMBER ENVIRONMENTAL PARAMETERS
Real-time temperature, humidity, and barometric pressure measurements were
collected at 1 -min intervals using WEATHERtronics sensors mounted inside the test
chamber. A Compaq portable computer logged the temperature, relative humidity,
and barometric pressure data, together with the clock time, onto an internal hard disk
drive. An Epson FX-85 dot-matrix printer was used to print a hard copy of the data in
real time.
4.1 TEMPERATURE
The temperature within the ACE Lab test chamber was measured at 1 -min
intervals using two thermocouples connected to an Omega TAG 80 thermocouple
amplifier and linearizer. The temperature was monitored at two locations on the east
wall of the test chamber—at the sampling inlet on the east wall located approximately
1.5 ft from the ceiling; and on the same wall at a level of 1 ft from the floor. The
temperature in the ACE Lab was controlled with dual thermostats using a dedicated
air conditioning unit.
The temperature measuring equipment was checked against a set of certified
thermometers (no. 9848) which were traceable to NIST. The thermocouple at the
sampling inlet read 0.6°F higher than the NIST-traceable thermometer. The thermo-
couple located approximately 1 ft from the floor read 1.9°F lower than the NIST
thermometer. The temperature data collected at the sampling inlet was corrected by
subtracting 0.6°F from all data points; the temperature data collected 1 ft from the
floor was corrected by adding 1.9° to the data points. The temperature data are
summarized in Table 1.
4.2 RELATIVE HUMIDITY
Humidity measurements were collected within the ACE Lab test chamber at
1-min intervals in units of percent relative humidity using a WEATHERtronics 5120-B
portable humidity probe located on the east wall of the lab. The humidity in the Ace
Lab was controlled by a dedicated air conditioning unit which dehumidifies the supply
air and by a solenoid-controlled pneumatic atomizer which adds humidity via the air
inlet duct at a controlled rate.

humidity by placing the sensor inside a glass container containing a saturated salt
solution of lithium chloride in water, and at 75% relative humidity using a saturated salt
solution of sodium chloride in water. At 12% relative humidity, the humidity probe was
low by 6.1%; at the 75% humidity level, the probe was low by 7.3%.
The humidity recording equipment was also checked against a wet bulb/dry
bulb psychrometer. The two thermometers in the psychrometer were checked against
a thermometer traceable to the National Institute of Standards and Technology (NIST)
thermometers. At a relative humidity of 39%, the humidity probe in the test chamber
read 6.2% lower than the relative humidity measurement by the psychrometer. The
manufacturer of the WEATHERtronics humidity probe did not recommend adjusting
the factory-set calibration settings; therefore, a correction factor of 6.2 was applied to
all relative humidity measurements. The relative humidity data are summarized in
Table 2.
4.3 BAROMETRIC PRESSURE
The barometric pressure within the ACE Lab was measured at 1-min intervals
using a WEATHERtronics 7105-A analog output barometer located on the east wall of
the test chamber. The barometric pressure was not controlled. The analog barometer
was checked against a barometer traceable to the NIST. The barometric pressure
instrument in the test chamber read 0.10 in Hg lower than the mercury barometer
traceable to NIST. A correction factor of 0.1 in Hg was thus added to all barometric
pressure data. The barometric pressure data are summarized in Table 3.

4.4 AIR EXCHANGE RATES
Air exchange rates within the test chamber were controlled for all experimental
runs. Air was exhausted from the test chamber at an air exchange rate of
approximately 1 per hour with General Metal Works Hi-Vol blower equipped with Accu-
vol flow controllers. The air exchange rate was monitored using sulfur hexafluoride
(SF6) gas, the reference gas in this study.
4.5 AIR MIXING
Commercially available box fans were used to increase air mixing within the
ACE Lab chamber. The speed and location of these fans were adjusted to achieve
good air mixing conditions. Smoke tubes were used to check the air mixing patterns
within the test chamber.

SECTIONS
DELIVERY OF SF6 AND PDCB INTO THE TEST CHAMBER
Sulfur hexafluoride (99.8% pure) was delivered to the test chamber from a
compressed gas cylinder (Matheson lot no. J61-0231-A3) via Teflon tubing. The
cylinder pressure was reduced from 320 psig to approximately 78 psig using a two-
stage pressure regulator (Matheson no. 8L 530). The pressure was further reduced to
approximately 17 in of H2O with a low pressure regulator (Matheson no. 3701). The
flow of SF6 into the test chamber was controlled by a double-pattern fine metering
valve (Nupro no. SS-4MGD) positioned downstream from the low pressure regulator.
This fine metering valve was used for accurate flow control down to 1 mL/h. The flow
rate of the SF6 was measured with volumetric buret and stopwatch using the thin-film
bubble method. The flow rate was adjusted to maintain the air concentration inside
the test chamber below 500 ppb.
p-Dichlorobenzene was introduced into the chamber by sublimation of solid
crystals. A flat metal pan (12 in x 10 in) containing PDCB crystals was placed inside
the chamber in front of the room air inlet. The initial and final weights of PDCB
introduced into the test chamber were 1,877.5 g and 1.661.1 g, respectively. The
difference between initial and final weights (216.4 g) was the mass of PDCB sublimed
during the pilot run.

SECTION 6
SAMPLING AND ANALYSIS OF SULFUR HEXAFLUORIDE
IN TEST CHAMBER AIR
6.1 SAMPLING OF TEST CHAMBER AIR
A continuous sample of test-chamber air was collected at the outlet of the test
chamber. A Gast two-cylinder vacuum pump pulled air from the test chamber through
Teflon tubing into a set of 0.25-mL sampling loops. A 0.25-mL aliquot of test-chamber
air was automatically injected at 7.5-min intervals into a Varian 3700 gas
chromatograph (MRI no. 8579) using a Carle double-loop gas-sampling valve system
(Model no. 2014). The sampling valve injected the contents of one of the matched
loops (0.25 mL) while the other loop was being flushed with test chamber air. Each
rotation of the valve repeats the process with the alternate loop. The gas-sampling
valve was rotated by a motor-driven actuator activated by a relay device controlled by
a Compaq computer through an RS-232 interface.
The sampling interval was determined experimentally based on the time
required for SF6 and the test compound to clear their respective GC columns.
Instrument parameters, such as column type, column length, and oven temperature
were selected to optimize peak resolution and retention time. The injection of SF6 into
the GC (side A) was synchronized with the injection of the test compound into GC
column B so that they occurred simultaneously.
6.2 ANALYSIS OF SF6 IN AIR
A Varian gas chromatograph equipped with dual columns (A and B) and dual
detectors (ECD and FID) was used to analyze air samples collected from the test
chamber. SFe was analyzed on column A using an electron capture detector (ECD).
The following instrument parameters were used:
Instrument: Varian 3700 gas chromatograph
Detector: Electron Capture (ECD)
Column (side A): Carbosieve S-ll (120/140 mesh);
1.2 m x 2 mm ID; glass
Carrier gas: Nitrogen
Carrier gas flow rate: 30 mL/min
Injector temperature: 250°C
A-15
-------
Column temperature: 220°C
Detector temperature: 300°C
The analog output of the GC was processed by a Varian CDS-111 chroma-
tography data system (MRI No. 8492) which automatically quantified the chromato-
gram using preset processing parameters. The area counts and retention times of
each peak were computed and printed on a dot-matrix printer. The integrator was
activated simultaneously with the sample injection by a relay device controlled by a
Compaq computer. This initiated the signal monitoring period. The CDS-111 auto-
matically returned to the READY mode following computation and printout of the
report. A Heath (Model SR 204) strip chart recorder recorded the chromatogram and
served as a backup to the CDS-111 integrator.
6.3 GC/ECD CALIBRATION PROCEDURES
The GC/ECD was calibrated over a range of 5 to 500 ppb using a series of SF6
standards prepared in Tedlar gas sampling bags. A neat concentration of SF6 was
prepared by flushing a 100-mL glass sampling bulb with SF6 from a f^iatheson lecture
bottle (Lot no. J81-0045-00) for approximately 4 min. The stopcocks of the glass bulb
were closed sequentially to avoid pressurizing the SF6 gas. The glass bulb had a
silicone septum midway down the length of the bulb. Aliquots of the neat SF6 were .
extracted from the glass bulb using a gastight syringe to prepare working standards of
10,000- and 2,000-ppm SF6.
The series of seven SF6 standards was prepared by diluting 1.0- and 0.5-mL
aliquots of the 10,000 ppm SF6 standard, and 1.5-, 1.0-, 0.5-, 0.25-and 0.05-mL of the
2,000 ppm SF6 standard with high purity air to a volume of 20 L to obtain the following
concentrations: 500, 250, 150, 100, 50, 25, and 5 ppb. The dilution volumes were
metered using a calibrated dry gas meter (Singer Co., MRI no. 9044) into clean, dry
Tedlar gas sampling bags. The Tedlar bags have Swagelok fittings that allowed the
injection of SF6 gas through silicone septa using Hamilton gastight syringes.
Contamination of the Tedlar gas sampling bags was avoided by thoroughly
rinsing them with clean compressed air. The Tedlar bags were evacuated with a
vacuum pump, then filled with compressed air (Burnox UN 1002). This process was
repeated three times. Gastight syringes were rinsed with hexane (Burdick and
Jackson, high purity) and air-dried prior to use.
Each Tedlar bag containing an SF6 gas standard was attached to a Teflon
sampling line and introduced into the GC through 0.25-mL sampling loops using a
Gast two-cylinder pump. The setup for the introduction of the SF6 standards into the
GC is similar to the setup for the introduction of the sampled air from the test
chamber. The only difference was in the length of Teflon tubing through which the
gas must pass to reach the sampling loops. Each standard was injected four times
(two injections per sampling loop).

SAMPLING AND ANALYSIS OF p-DICHLOROBENZENE
IN TEST CHAMBER AIR
7.1 SAMPLING OF TEST CHAMBER AIR
A continuous sample of test-chamber air was collected at the outlet of the test
chamber. A Gast two-cylinder vacuum pump pulled air from the test chamber through
Teflon tubing into a set of 1.0-mL sampling loops. A 1.0-mL aliquot of test-chamber
air was automatically injected into a Varian 3700 gas chromatograph (GC) using a
Carle double-loop gas-sampling valve system. The sampling valve injected the
content of sampling loop (1.0 mL) while the other loop was being flushed with test
chamber air. Each rotation of the valve repeated the process with the alternate loop.
The gas-sampling valve was rotated by a motor-driven actuator activated by a relay
device controlled by a Compaq computer through an RS-232 interface.
The sampling interval was determined experimentally based on the time
required for the PDCB and the SF6 reference gas to clear their respective GC
columns. The sampling interval for p-dichlorobenzene was set at 7.5 min to match the
sampling interval for the SFe.
7.2 ANALYSIS OF PDCB IN AIR
The Varian gas chromatograph equipped with dual columns (A and B) and dual
detectors (ECD and FID) was used to analyze the test chamber air. PDCB was
analyzed on column B using a flame ionization detector (FID). The following
instrument parameters were used in the pilot study for PDCB:
Instrument: Varian 3700 gas chromatograph
Detector: Flame ionization (FID)
Column (side B): 1% SP-1000 on 60/80 Carbopack B;
0.6 m x 2 mm ID, stainless steel
Carrier gas: nitrogen
Carrier gas flow rate: 30 mL/min
Injector temperature: 250°C
Column temperature: 220°C
Detector temperature: 300°C
A-17
-------
The analog output of the GC was processed by an analog-to-digital converter
based on a Wintek micro control system module interfaced with a Compaq computer.
The computer was running a GWBASIC data logging and integration software called
ACE999, version V09/22/88 that was modified specifically for this project by Dr.
George Scheil of MRI. The integration program was activated simultaneously with the
sample injection. The data system automatically quantified the chromatogram using
preset processing parameters. The area counts and retention times of each peak
were computed and printed on an Epson FX-85 dot-matrix printer. The GC data
output and integration data were also saved to a hard disk drive. A Heath (Model SR
204) strip chart recorder recorded the chromatogram and served as a backup to the
data logger.
7.3 GC/FID CALIBRATION PROCEDURES
The GC/FID was calibrated using a series of four p-dichlorobenzene (PDCB)
standards. The PDCB standards were prepared by diluting 0.10-, 0.05-, 0.025-, and
0.010-mL aliquots of a standard mixture of 10 g of PDCB (Aldrich, high purity) in
50-mL hexane (Burdick and Jackson, high purity) with 20-L of high purity air to obtain
standard concentrations of 76, 38, and 15 ppm PDCB. The dilution volume was
metered using a calibrated dry gas meter (Singer Company, MRI no. 9044) into clean,
dry Tedlar gas sampling bags. The Tedlar bags had Swagelok fittings that allowed the
injection of the test compound through silicone septa using Hamilton gaslight syringes-
Contamination of the Tedlar gas sampling bags was avoided by thoroughly
rinsing them with clean compressed air. The Tedlar bags were evacuated with a
vacuum pump, then filled with compressed air (Burnox UN 1002). This process was
repeated three times.
Each Tedlar bag containing a PDCB standard series was attached to a
sampling port and introduced into the gas chromatograph via the sampling loc The
volumes of the gas sampling loops were not perfectly matched; therefore, each
sampling loop was calibrated separately.

SECTION 8
DATA ACQUISITION AND SAMPLE IDENTIFICATION
Data collection utilized both manual and computerized acquisition systems. All
pilot study activities were recorded using permanent ink in the project notebook. Each
person who recorded data signed and dated each sheet. Strip charts, magnetic disk,
etc., were labeled with a format identifier, project number, date, the ID(s) of the
instrument, and the name of the person responsible for the data.
The Varian CDS-111 integrator identified each sample injection with a
sequential number. The injection numbers were printed on a continuous paper
printout along with the area counts of each detected peak (side A). These injection
numbers were manually transcribed onto the GC/ECD output on the strip chart
recorder so that integration data could be linked to the chromatogram.
The GC/FID data were integrated using the ACE999 computer program
(V09/22/88) and saved to a Compaq computer hard disk drive under a unique and
sequentially numbered file name. The area counts of detected peaks (side B) were
also printed on an Epson FX-85 printer along with the file name. These file numbers
were manually transcribed onto the GC/FID output on the strip chart recorder so that
integration data can be linked to the chromatogram.
The date and time stamp on the temperature, humidity, and barometric
pressure data linked these data to GC data output.

SECTION 9
DATA ANALYSIS
9.1 APPROACH
Several statistical analysis steps were followed to assess sink effects. First, the
calibration data for both SF6 and PDCB were evaluated by means of linear regression
analysis to quantify the functional relationship between area counts and concentrations
for each gas. In each case, first-order and second-order models in concentration were
evaluated for their applicability. Residuals and error estimates from each model were
carefully examined and assumptions of variance homogeneity and of normality of
residuals were checked. All data analyses were performed using SYSTAT, version
3.0, a commercially available MS-DOS statistical software package.
For each set of calibration data (SF6 and PDCB), regression coefficients and
their standard error were estimated by least-squares method. Results were docu-
mented in an analysis-of-variance (ANOVA) table.
Next, from each calibration equation, decay concentrations were computed by
inverse regression (calibration equation) using the measured area counts from each
test run. These concentration data were tabulated and plotted versus time.
A decay curve, C, = C0 e'M, was fitted to the SF6 air concentration data collected
at 7.5-min intervals after injection of SF6 gas had ceased. The parameter estimates,
C0, the SF6 concentration at time t = 0, and A, the air exchange rate, were estimated
by linear regression of the log-transformed SF6 concentrations vs. time. Again,
residuals of the model were carefully examined to test for fit of the model. Analysis of
variance provided tests of significance of the parameters, estimates of their standard
error, as well as the standard error of the estimate. Potential improvement by adding
a second-order term in the linear model was investigated.
Next, the decay curve for PDCB concentrations over time was determined by
regression analysis. Similarly to the SF6 data analysis, the concentrations were log-
transformed since the shape of the curve was expected to be a negative exponential.
First- and second-order models were fitted to the log-transformed concentration data
against time. Residuals were examined in each case to test for model adequacy.
The ANOV'A provided parameter estimates, their standard errors, and the standard
error of the estimate.

SECTION 10
RESULTS AND DISCUSSION
10.1 SFR CALIBRATION RESULTS
6
From the SF6 calibration procedure, a set of 14 area measurements were
obtained over a concentration range from 5 to 500 ppb. Duplicate measurements at
each of seven concentration levels were available. These data were analyzed by
regression analysis. Even though a first-order polynomial fitted to the data resulted in
an R-squared of 99.50%, examination of the residuals suggested a second-order
polynomial. A second-order polynomial showed significant improvement in the fit: an
R-squared of 99.98%, but most importantly, a reduction in the standard error of the
estimate of 63,462 (linear relationship) down to 13,811 (quadratic relationship). Thus,
the best relationship between area counts and concentration was found to be
quadratic in the concentration range of interest. SF6 data and regression results are
shown in Table 4. The calibration data and fitted curve are plotted in Figure 1.
10.2 PDCB CALIBRATION RESULTS
From the PDCB calibration procedure, a small set of data (duplicate or triplicate
measurements of PDCB at three concentration levels for each sampling loop) was
available to test for linearity of the instrument response in the concentration range
from 15 to 80 ppm. Regression analysis was used separately on the data for each of
the two sampling loops. The regression coefficient differed between the two loops,
and the fit of the model to the data was better for loop A than for loop B as shown by
the standard error of the area estimate (1,869 for loop A vs. 5,186 for loop B).
However, in both cases, the linear relationship was significant at the 0.001 level with
R-squared values above 92%. For each loop, the coefficient of a second-order term
in concentration was not statistically significant. The linear relationship was accepted
in the concentration range from 15 to 80 ppm. PDCB data and regression results are
shown in Table 5. The calibration results and fitted curve are plotted in Figure 2.
10.3 SF6 DECAY IN EMPTY TEST CHAMBER
Two sets of experiments were performed with SF8 in the ACE lab test chamber,
one with gypsum wall board on all six sides of the chamber, and one with the addition
of wall-to-wall carpeting on the floor.

This approach was taken to confirm that there was no significant sink effect of SF6
with carpeting. The results are shown separately below.
Using the calibration equation for SF6 determined above, SF6 concentrations
were calculated by inverse regression for a total of 40 area counts. These data are
presented in Table 6. The SF6 concentrations in the room without carpeting were
plotted versus time and are shown in Figure 3.
To determine the air exchange rate in the room, the natural logarithm of the
concentrations were regressed against time. The ANOVA results are shown in
Table 6. A straight line provided an adequate fit to the log-transformed data
(R-Squared of 99.91% and a standard error of the concentration estimate of
1.04 ppb). A second-order polynomial was fitted to the data to test whether adding a
second-order term would significantly improve the fit of the model. The second-order
term was statistically significant (p < 0.0001), however, the corresponding t-statistic
(-8.69) was an order of magnitude smaller than that obtained for the first-order term
(-89.56), with no significant improvement in the standard error of the concentration
estimate (1.02 ppb as compared to 1.04 ppb). It was concluded that the simple
exponential concentration decay obtained from taking the exponential of the straight
line relationship provided a significant fit to the data (see Figure 3). The slope, -0.94, of
the regression line of the log-transformed concentration versus time provides an
estimate of the air exchange rate. The decay curve of SF6 can thus be summarized by
the following equation:
Estimated SF6 Cone (ppb) =413 Exp (-0.94 x Time) (A-1)
where time is in units of hours.
10.4 PDCB DECAY IN EMPTY TEST CHAMBER
A total of 40 PDCB area counts were obtained from the two loops, A and B,
simultaneously over the same time period as the SF6 area counts. However, only the
results from loop A were analyzed since the calibration results from loop B were
discarded in this pilot study. The calibration results from loop A obtained above were
used to calculate PDCB concentrations by inverse regression. The data are presented
in Table 7 and plotted in Figure 4.
As before, a linear model was fit to the log-transformed PDCB concentrations.
Both a first-order and a second-order model were fit to the data over time. The
ANOVA results are presented in Table 7. In this case, the second-order model
provides a better fit to the data than does the first-order model. This is shown by the
improvement in the R-squared values (99.95% vs. 99.47%) and in the standard error of
the concentration estimate (1.02 ppm vs. 1.08 ppm).

-------
Most important is the fact that the coefficient of the quadratic term, 0.037, is
statistically significant at the 0.001 level, with a corresponding t-statistic of 12.63. The
t-statistic corresponding to the linear term of -0.86 is -59.16. The discrepancy between
these two statistics is not as pronounced as that between the corresponding statistics
obtained with SF6. It was concluded that the following equation would best be
described by the following relationship:
Estimated PDCB Cone (ppm) = 66 Exp (-0.86 x Time + 0.037 x Time2) (A'2)
The fitted decay curve is shown in Figure 4.
To estimate the sink effect, the air exchange rate of -0.94 obtained during the
same experiment from the SF6 results and a starting PDCB concentration of 66 ppm
were substituted in the simple decay equation, yielding the following relationship
without sink effect:
Estimated PDCB Cone (ppm) = 66 Exp (-0.94 x Time) (A'3)
This relationship is also shown in Figure 4 and is the curve below that fitted to the raw
data. The sink effect can thus be estimated by differencing the two equations, that is:
Estimated Sink Effect = 66 [Exp (-0.86 x Time + 0.037 x Time2) - Exp (-0.94 x Time)] (A"4)
The sink effect is plotted in Figure 5 to illustrates its behavior. The sink effect reaches
a maximum of 3.71 ppm at approximately 1.67 h (1 h and 40 min) after the source has
been shut off. The time at which the sink effect reaches its maximum is independent
of the starting concentration, C0 = 66 ppm.
10.5 SF6 DECAY IN TEST CHAMBER WITH CARPET
The data obtained with SF6 in the room after wall-to-wall carpet was installed on
the floor, were analyzed similarly to the SF6 data obtained in the room without carpet.
A total of 40 measurements were available. Results similar to those obtained with SF6
in the room without carpeting were obtained here.
Again, the second-order term in the model fitted to the log-transformed
concentrations was statistically significant (p < 0.0001) with an even more pronounced
difference in the t-statistics used in testing the significance of the linear (t = -120.28)
and the quadratic (t = + 9.61) terms of the quadratic model. The standard error of
the concentration estimate improved slightly from 1.04 ppb (linear fit) to 1.02 ppb
(quadratic fit). All ANOVA results are presented in Table 8. The measured
concentration and the fitted decay curve are plotted against time in Figure 6.

-------
Examination of the residuals from both models showed that the quadratic
model for the log-transformed data provided a slightly better fit than the straight line.
The fact that the coefficient of the second-order term is positive could indicate that a
slight sink effect of the SF6 with carpet might be present. A possible explanation
could be that the carpet used for this pilot study was not fitted to the floor and did not
lay flat at the corners of the room. Air could have been trapped under these carpet
corners in dead-air spaces and thus released the SF6 more slowly, thus appearing as
a sink effect. In the experimental runs, the carpet will be cut and fit to the exact size
of the floor to circumvent this effect.
As a result, the decay function can be summarized as follows:
Estimated SF6 Cone (ppb) = 291 Exp (-0.89 x Time) (A-5)
NOTE: Air mixing characteristics within the test chamber were investigated in
the pilot study. Preliminary tests using SF6 tracer gas were conducted to determine
the mixing conditions within the chamber. SF6 was injected into the test chamber at a
controlled flow rate to achieve a steady-state concentration. Air concentration
measurements were conducted at 27 locations within the test chamber. The sampling
locations were determined by dividing the test chamber into a three dimensional grid
(3x3x3). The air was sampled at the center point of each of the 27 cubic volumes
as defined by the three dimensional grid. The air concentration of SF6 at each of
these sampling locations were compared to air concentration measured at the
sampling inlet located at the exhaust outlet on the east wall the test chamber. These
air concentrations were within ±8% of the air concentration measured at the sampling
inlet.

-------
SECTION 11
CONCLUSIONS
The pilot study demonstrated that SF6 did not significantly adsorb or absorb into
gypsum wall board and conformed to the simple mathematical dilution model for the
two chamber configurations (with and without carpet) proposed for the initial test runs.
It is anticipated that a sink effect can be estimated by the existence of a
positive second-order term in the linear regression of the log-transformed
concentrations of the test compound vs. time, if that term is statistically significant.
This relationship could be determined by the following model:
where C, = PDCB air concentration at time (t)
C0 = estimated PDCB air concentration at time t = 0
B, D are the first and second order decay parameters
t = time duration (h) from withdrawal of PDCB source
Using the air exchange rate, A, obtained for SF6, the reference gas, and C0, the
starting test compound concentration, the sink effect for the test compound can be
estimated by differencing the two equations at time t as follows:
CQ 6 6* ~ CQ[B O* ~0"
It is thus anticipated that the sink effect will be estimated in the form of a
functional relationship between C0, the test compound concentration at time t = 0; A,
the SF6 air exchange rate; B and D, the decay coefficients of the test compound; and
time.

STABILITY OF SFB AND PDCB IN TEDLAR GAS SAMPLING BAGS

-------
STABILITY OF SF6 AND PDCB IN TEDLAR GAS SAMPLING BAGS
The stability of SF6 and PDCB was measured by analyzing aliquots from
standard series of both compounds prepared in Tedlar gas sampling bags.
1. Stability of SF6 in Tedlar bags
A series of seven SF6 standards was prepared in Tedlar gas sampling bags
over a range of 5 to 500 ppb. A neat concentration of SF6 was prepared by flushing a
100-mL glass sampling bulb with SF6 from a Matheson lecture bottle (Lot
No. J81-0045-00) for approximately 4 min. The stopcocks of the glass bulb were
closed sequentially to avoid pressurizing the SF6 gas. The glass bulb had a silicone
septum midway down the length of the bulb. Aliquots of the neat SF6 were extracted
from the glass bulb using a gastight syringe to prepare working standards of 10,000
and 2,000 ppm SF6.
The series of seven SF6 samples was prepared by diluting 1.0- and 0.5-mL
aliquots of the 10,000-ppm SF6 standard, and 1.5-, 1.0-, 0.5-, 0.25- and 0.05-mL
aliquots of the 2,000-ppm SF6 standard with high purity air to a volume of 20 L to
obtain SF6 concentrations of 5, 25, 50, 100, 150, 250, and 500 ppb. The dilution
volumes were metered using a calibrated dry gas meter (Singer Co., MRI No. 9044)
into clean, dry Tedlar gas sampling bags. The Tedlar bags (Nutech Corp.) had
Swagelok fittings that allow the injection of SF6 gas through silicone septa using
Hamilton gastight syringes.
In addition, a blank sample was prepared using the same procedure, except
that no SF6 was injected into the Tedlar bag.
Triplicate 0.25-mL aliquots from each of the eight Tedlar bags were injected into
the GC using a Hamilton gastight syringe at the following time intervals as measured
from the time at which the sample was prepared: less than 1 h, 24 h, 48 h, 72 h,
96 h, and 120 h. Area counts were obtained from the triplicate injections of the seven
SF6 standards and the blank. The area counts obtained at each time interval were
plotted against SF6 concentration (Figure B-1). The relationship between area counts
and concentration levels was quantitated by means of regression analysis using
Lotus 1 -2-3. A second-order model best described the relationships for the data
obtained at each time interval. Measured area counts and regression results at each
time interval are presented in Table B-1.
Next, area counts obtained from the triplicate samples from each Tedlar bag at
time intervals 24 to 120 h were averaged and then compared with the average area
counts measured at less than 1 h. The relative changes in SF6 area counts at each
time interval are listed in the fourth column of Table B-1.

B-7
-------
The air concentrations of SF6 in the Tedlar bags decreased slightly over time as
shown by the slightly decreasing measured area counts. The decrease in absolute
SF6 area counts over time was greater at higher concentration levels; however, the
relative percent change in area counts over time was greater for the lower
concentrations. This study suggests that SF6 is stable in Tedlar bags. After an
interval of 24 h following preparation, the decreases of SF6 area counts ranged from
0.8% to 4.8%. After 120 h, the losses ranged from 3.5% to 8.9% (Table B-1).
After 120 h, the Tedlar bags containing SF6 were evacuated, filled with 20 L of
clean air, and heated to approximately 100°C. These bags were then analyzed using
the same procedure as described above. No residual SFe was detected in any of the
Tedlar bags. This suggests that the losses were most likely due to permeation of SF6
through the bag material rather than to adsorption onto the Tedlar bag surface.
2. Stability of PDCB in Tedlar Bags
A series of six PDCB standards was prepared in Tedlar gas sampling bags
over a range of 4 to 153 ppm. A stock standard solution of PDCB in hexane was
prepared by weighing to the nearest 0.1 mg approximately 5 g of PDCB (Aldrich
Chemical, high purity, Lot No. 06205BV) which was transferred to a 50-mL volumetric
flask and diluted to the mark with hexane (Burdick & Jackson, high purity, Lot No.
AM062). The PDCB standards were prepared by diluting 0.200-, 0.100-, 0.050-, 0.020-
, 0.010-, and 0.005-mL aliquots of the stock standard mixture with 20 L of high purity
air to obtain standard concentrations of 153, 76, 38, 15, 8, and 4 ppm PDCB in air.
The dilution volumes were metered using a calibrated dry gas meter (Singer Co., MRI
No. 9044) into clean, dry Tedlar gas sampling bags. The Tedlar bags (Nutech
Corporation) have Swagelok fittings that allowed the injection of PDCB through
silicone septa using Hamilton gastight syringes.
In addition, a blank was prepared with the standard series using the
.preparation procedures specified above, except that no PDCB was injected into the
Tedlar bag.
Triplicate 1.0-mL aliquots from each Tedlar bag were injected into the GC using
a Hamilton gastight syringe at the following time intervals as measured from the time
at which the sample was prepared: less than 1 h, 6 h, 24 h, 48 h, 72 h, 96 h, 120 h,
and 144 h. Area counts were obtained from the triplicate injections of the six PDCB
concentrations and the blank. The relationships between area counts and PDCB
concentrations were quantitated by means of regression analysis using Lotus 1 -2-3. A
first-order linear model was used to best describe the relationship for the data
obtained at each time interval.
The least-squares fit of the linear model to the data collected over the entire
PDCB concentration range appeared to worsen for each successive time interval. A
visual inspection of the plots (PDCB area counts versus concentration) revealed that
B-8
-------
Tedlar bags previously used for PDCB standards in the Pilot Study and new (unused)
Tedlar bags behaved slightly differently. Area count data for "new" bags and "reused"
bags were therefore separated and regression analyses were rerun. New Tedlar bags
were consequently associated with the 38- and 76-ppm PDCB samples; reused Tedlar
bags were associated with the 4-, 8-, 15-, and 153-ppm samples. The least-squares fit
of the linear model to the two data sets treated separately improved and did not
appear to worsen for each successive time interval. The results are presented in
Tables B-2 and B-3, for new and reused bags, respectively.
The area counts obtained for each time interval were plotted against PDCB
concentration of both "new" and "reused" Tedlar bags (Figures B-2 and B-3). PDCB
concentrations in the Tedlar bags decreased over time. The decrease in absolute
PDCB concentrations over time, as measured by the loss of area counts, was greater
for the higher concentration levels; however, the relative percent change over time was
greater for the lower concentration levels. This study suggests that PDCB is not
stable in Tedlar bags. After a time interval of only 6 h following preparation, the loss
of PDCB ranged from 3.9% to 14.6% (Table B-3). After 144 h, the PDCB losses
ranged from 16.8% to 28.7% (Table B-3).
3. PDCB Recovery
After 120 h, those new or reused Tedlar bags containing 15, 38, 76, or
153 ppm PDCB were evacuated, filled with 20 L of clean air, and heated to
approximately 100°C. These bags were then analyzed using the same procedure as
described above. Residual PDCB levels were detected in all Tedlar bags. The
percent PDCB levels recovered in the bags ranged from 17.9% to 23.1% as shown in
Table B-4. Recoveries were calculated as a function of PDCB concentrations obtained
from the linear equations at less than 1 h after preparation (Tables B-1 and B-2). This
suggests that the losses were due in part to adsorption of PDCB onto the interior
surface of the bag. The adsorbed PDCB was driven off the Tedlar material when
heated. This "sink effect" was probably not the only mechanism at work; PDCB was
probably lost due to permeation through the Tedlar material.
4. Additional PDCB Stability Studies
Additional stability tests were conducted on PDCB for time intervals less than
6 h in duration. A series of six PDCB standards in the range of 1 to 76 ppm was
prepared in Tedlar gas sampling bags. A stock standard solution of PDCB in hexane
was prepared by weighing to the nearest 0.1 mg approximately 5 g of PDCB (Aldrich
Chemical, high purity, Lot No. 06205BV) which was transferred to a 50-mL volumetric
flask and diluted to the mark with hexane (Burdick & Jackson, high purity, Lot
No. AM062). The PDCB standards were prepared by diluting 0.100-, 0.050-, 0.020-,
0.010-, 0.005-, and 0.00125-mL aliquots of the stock standard mixture with 20 L of
high purity air to obtain standard concentrations of 76, 38, 15, 8, 4, and 1 ppm PDCB
in air. Aliquots (1.0 mL) from each Tedlar bag were injected in duplicate in series into

the GC using a HamHton gaslight syringe. After completion of the first series of
injections, the series was repeated over a total time period of 6 h.
Duplicate area counts were obtained for the six PDCB concentrations and the
blank. The relationship between average area counts and PDCB concentration was
quantrtated by means of regression analysis using Lotus 1 -2-3. A quadratic model
was used to best describe the relationship for the data obtained for each series of
injections. The data obtained for the 6-h stability study and the regression results are
presented in Table B-5.
The relative change in average PDCB area counts was calculated for each
subsequent series of injections relative to the area counts obtained for the first series
of injections. These data are listed in the sixth column of Table B-5.
A third stability study was conducted on an 8-ppm PDCB standard prepared in
a Tedlar bag using the same procedure as described above. Aliquots (1.0 mL) of this
standard were injected sequentially into the GC for a period of 2 h. The area counts
and relative changes (%) obtained for these injections are presented in Table B-6.
During the 2-h period, the maximum loss of PDCB in the Tedlar bag was 5.14%.
After 72 h, 1.0-mL aliquots of the Tedlar bag containing the 8-ppm PDCB
standard were analyzed using the same procedure as described above. The
reduction of PDCB concentration, as measured by the reduction in area counts, in the
Tedlar bag ranged from 44.5% to 48.8%. The results are presented in Table B-7.
5. Additional PDCB Recovery Study
The bag used previously was then evacuated, filled with 20 L of clean air,
heated to approximately 100°C, and reanalyzed. The residual PDCB concentration in
the bag ranged from 25.5% to 28.4% relative to the original PDCB concentration at
72 h after preparation. The results are presented in Table B-8.
These follow-up studies confirmed the results of the first stability study and
suggested that PDCB standards should be analyzed less than 1 h after preparation to
avoid losses above 5% to 15%. This criterion was followed during the remainder of
this project. The preparation time was noted on all Tedlar gas sampling bags
prepared for this project. Both PDCB and SF6 standards were run within 1 h after
preparation. If this time constraint was not met, the standard was rejected and
prepared again.

ANALYTICAL AND STATISTICAL RESULTS FOR RUN 11
H-1
-------
SECTION 1
BACKGROUND
A total of 12 runs were performed in the ACE Laboratory following the
procedures detailed in this report. However, technical problems were encountered
during run 11, which resulted in the data being suspect. Additionally, the analysis of
run 11 results showed that the data from this run exhibited patterns unlike those of the
remaining runs. Therefore, the suspect data were not included with the other 11 runs
in the main body of this report. However, it was decided to include the data from
run 11 in this appendix for completeness. As an exploratory effort, some changes
were made in the way the data were analyzed. A discussion of the technical problems
encountered during run 11 and of the analysis approach is given below.
1.1 TECHNICAL PROBLEMS WITH RUN 11
Two problems were encountered during run 11: one was related to the SF6
performance audit sample (PAS) not meeting DQO criteria for accuracy; the other to
a malfunctioning of the integrator. These problems are fully explained below.
1.1.1 Failure of the SF9 Performance Audit Sample to Meet the Accuracy Criterion
After the data were collected for run 11, the results of the performance audit
sample (PAS) were calculated from the standard curve. The results of the analysis
were submitted to the Quality Assurance Manager (QAM). The air concentration of
each analyte in the PAS, as measured by the GC system, was compared to the calcu-
lated air concentration of the PAS as prepared by the QAM. The results (in units of
percent of air concentration found over actual concentration) were 88.7% and 73.6%
accuracy for PDCB and SF6, respectively. PDCB results were thus within the range
specified in the QAPjP (i.e., 85% to 115%); however, SF6 did not meet the accuracy
objective. The quality of the data for run 11 was therefore considered questionable. A
complete discussion of QA results for the entire study can be found in Section 11 of
this report.
1.1.2 Integrator Failure
Experimental run 11 was started on August 21, 1991, at 8:18 pm, after both the
GC/FID and GC/ECD were calibrated and the check standards were found to be
within the specifications stated in the QAPjP. The computer-controlled auto-sampling
H-3
-------
system, gas chromatagraph, and data acquisition system were working properly. The
experiment was unattended during the evening hours from approximately 9:00 pm to
7:00 am. All systems were functioning normally when checked at 7:00 am. The data
output was examined at that time to determine when PDCB concentration in the text
chamber had reached equilibrium.
Both the SF6 and PDCB were withdrawn from the chamber at 10:00 am on
August 22 after equilibrium had been maintained for a 6-h period. The system was
monitored by the GC operator until approximately 5:00 pm when the system was left
unattended until 6:19 am on the following day at which time the computer printout was
immediately checked by the GC operator. It was apparent that the integrator was
reporting zero area counts while the chromatograms recorded on the strip chart
recorder were still showing visible peaks. The problem was diagnosed as a loss of
bias voltage in the integrator circuitry. An adjustment was made to restore it and the
integrator resumed reporting area counts that appeared to be consistent with the
chromatogram. An examination of the computer printout indicated that the failure
occurred at approximately 11:30 pm, that is, during the unattended portion of the run.
For analysis purposes, the instrument failure window needed to be determined.
Instrument failure was detected at time 33.8 h of the run at which point the instrument
bias voltage was adjusted. Thus, the end of the failure window was obviously set at
time 33.8 h. To determine at which point instrument failure began, the area counts for
both loops were examined from the real time data logger printout moving back in time
over a range of several hours. The sudden change of area counts at time 25.9 h was
thus the basis for the starting point of the failure window, resulting in a total length of
the failure window of 7.9 h. It should be noted that the exact time at which failure
started to occur could not be determined with certainty. There may have been a
gradual change as a result of the failure prior to the assumed time of 25.9 h.
1.2 DATA ANALYSIS OF RUN 11 RESULTS
The data analysis approach for run 11 results was similar to that followed for all
other runs (see Section 9 of this report). However, some adjustments or modifications
were made as follows.
• The high level of 74 ppm in the PDCB calibration range was excluded from the
statistical analysis. The results obtained at this high level affected the shape of
the calibration curves for both loops A and B in an unduly manner since the
calibration range of 0 to 74 ppm by far exceeded the experimental range
(maximum PDCB concentration in run 11 was 26 ppm). Thus the calibration
range was limited at 37 ppm.
• The PDCB calibration curves for loops A and B were estimated separately as
for all other runs. However, as an additional step, the pairs of coefficients
(intercept, linear and quadratic terms) for the two calibration curves (loops A
H-4
-------
and B) were then tested for significant differences. A joint calibration curve
(loops A and B combined) was estimated as a results of this analysis.
The estimation of the SF6 and PDCB decay models were unaffected by the
integrator failure window.

SECTION 2
RUN 11 RESULTS
2.1 ENVIRONMENTAL DATA
Temperature, relative humidity, and barometric pressure within the ACE
Laboratory test chamber were monitored at 1-min intervals throughout run 11. The
temperature was set between 72° and 76°F and was controlled within ±1.8°F (i.e.,
temperature range not to exceed 3.6°F). Temperature control within the test chamber
met the performance objective specified in the QAPjP.
The humidity within the test chamber was set between 35% and 55% and
controlled to within ±10% (i.e., % humidity range not to exceed 20%). The humidity
control met the performance objective set in the QAPj'P. A summary of the
environmental data for run 11 is presented in Table H-1. Barometric pressure was
monitored but not controlled.

2.2 PDCB EMISSION RATE
The emission rate of PDCB was calculated by subtracting the final weight from
the initial weight of the crystals and dividing this term by the duration of run 11. The
data are:
Initial weight: 419.7 g PDCB sublimed: 95.8 g
. Final weight: 323.9 g Run 11 duration: 12.5h
Emission rate: 7,760 mg/h

2.3 CALIBRATION RESULTS
The calibration procedures and calculations for SF6 in run 11 were similar to
those used for all other runs. A second order equation best described the
relationship between area counts and SF6 concentrations for each loop in run 11. The
calibration data and the regression results for each loop are presented in Table H-2.
Calculated and predicted SF6 area counts are plotted versus concentration levels in
Figure H-1.
The following calibration equations were used in all subsequent data analysis
for run 11 when calculating SF6 concentrations from area counts:
Loop A: SF6 Area Counts = -1,887 + 1,455 Cone - 0.19 Cone2
Loop B: SF6 Area Counts = -1,993 + 1,422 Cone - 0.12 Cone2
The high PDCB spike level (74 ppm) results were discarded from the calibration
calculation as discussed earlier. Using the calibration data between 0 and 37 ppm
only, a quadratic equation was found to best describe the relationship between area
counts and PDCB spike levels. The separate loop A and loop B calibration equations
were as follows:
Loop A: PDCB Area Counts = -1,416 + 26,055 Cone - 125 Cone2
Loop B: PDCB Area Counts = -2,661 + 26,057 Cone - 129 Cone2
Next, the three sets of coefficients (-125 and -129; 26,055 and 26,057; and
-1,416 and -2,661) were compared for significant differences. This was done using
four regression models, starting with a six-parameter model, and successively
dropping one parameter at a time until the final three-parameter model was obtained.
Between each two steps, an F-test was performed to evaluate the relative contribution
of each set of two different coefficients using the residual sums of squares of each
model. This stepwise regression approach showed that estimating the two calibration
equations separately does not provide a significant improvement over a joint
calibration equation. In other words, the two equations above are not statistically
different from each other. All statistical tests were performed at the 5% significance
level.
The joint loops A and B calibration equation is thus estimated as:
Loops A and B: PDCB Area Counts = -2,038 + 26,056 Cone - 127 Cone2
The data and the regression results for the two loops are presented in
Table H-3. Calculated and predicted area counts are plotted versus concentration
levels in Figure H-2.

2.4 SF6 DECAY RESULTS
SF6 concentrations were calculated from the area counts by inverse regression
using the SF6 calibration equations for loops A and B, as appropriate. Calculated SF6
concentration levels are plotted versus time for the entire length of run 11 in
Figure H-3.
For run 11, a first-order exponential decay function was chosen to best fit the
data. A second-order model was also fitted to the data. However, for all practical
purposes, the first-order decay model, yielding an R-squared value of 99.98% was
selected without significant loss of fit. The regression results for SF6 run 11 are shown
in Table H-4.

• All data after time 34.1 h, using the cutoff criterion that all data following, and
including, the first concentration level below the LOQ will be excluded from the
decay modelling.
Thus, a total of 256 data points were available for modelling.
A segmented second-order exponential decay followed by a first-order linear
function (Eq. 10 in Section 9 of report) was found to best fit the data. The regression
parameters D, E, F, G and time T, and RMSE, a measure of fit of the model to the
data, are shown in Table H-5.
The calculated and predicted PDCB concentrations, along with the lower and
upper 95% confidence limits to the regression line, are plotted versus time in
Figure H-6. This plot also shows the SFe-based decay curve corresponding to the air
exchange rate of 1.43 and starting at the same level of 26 ppm.
2.6 ESTIMATION OF SINK EFFECT
The sink effect was estimated as a function of time by taking the difference
between the PDCB level estimated by the decay model and the PDCB level obtained
from the corresponding SF6 air exchange rate of 1.43. The differences are then
standardized by expressing them as a function of air exchange rather than time. The
estimated sink effect for Run No. 11 is plotted in Figure H-7, along with the previous
sink effects from runs 10 and 12.
Next, Table H-6 provides a means of comparing the three runs by calculating
the number of air exchanges necessary to lower the levels from 14 to 2 ppm, under
sink effect conditions and clearly shows that run 11 does not fit the patterns of the
other two runs.
The complete set of SF6 and PDCB data obtained from run 11 is shown in
Table H-7. These data can be obtained from the U.S. EPA address mentioned in
Appendix G.
