ABSTRACT
The objectives of this research project were to monitor air 1n and
around public access buildings for a broad range of organic and Inorganic
compounds; to measure emission rates of chemicals from building materials
as part of a chamber study; and to examine the relationships between chemi-
cals, building materials, human activities, and air exchange rates.
Activities associated with the field monitoring phase of the program
included sampling and analysis for volatile organics, nitrosamines,
pesticldes/PCBs, particulate mass, polynuclear aromatic hydrocarbons
(PNAs), metals, formaldehyde, radon, carbon monoxide (CO), nitrogen dioxide
(N02) and asbestos. Sampling was performed in six buildings: a new
hospital, office, and nursing home and an existing office, office/school,
and nursing home. The new buildings were monitored immediately after
construction and again one or two times after occupancy. At each building,
sampling was performed at three indoor locations and a single outdoor
location.
For the volatile organics, very high total levels of target organics
(>1 /ig/L) were measured in indoor air samples immediately after
construction. These levels decreased dramatically with time (>50 ng/L) to
the point where the outgassing of volatile organics from new building
materials no longer appeared to be a significant source of indoor
pollution. Aliphatic and aromatic hydrocarbons accounted for the majority
of volatile organics found in the new buildings. For the occupied offices
and hospital, halogenated organics were a significant contribution to the
Indoor air contamination level. There appeared to be no definite trend for
the oxygenated compounds although they were detected most often in the
office building.
Generally, Indoor levels of nitrosamines, pesticides/PCBs, PNAs,
metals, formaldehyde, asbestos, and radon were low. CO and N0£ were
111
-------
monitored only at the existing office with no general trends noted in the
data.
In areas where there was no smoking, Indoor concentrations for both
Inhalable (coarse) and respirable (fine) particulate mass were lower than
outdoor concentrations. In smoking areas, small changes in Inhalable
particulate were observed, whereas, large changes 1n respirable particulate
were noted.
The emission study was performed 1n two phases. During the first
phase, preliminary headspace experiments were performed to give a fast,
relatively inexpensive evaluation of emissions for all 31 materials tested.
In the second phase nine materials were evaluated using controlled chamber
experiments. Generally, the solvent-based materials showed the highest
emission rates followed by the plastic and rubber materials, and carpeting.
Building materials such as wall board, ceiling tile, and cement block
showed few volatile organic emissions. Data from the chamber tests
verified these trends. Measured emission rates compared well with field
monitoring data and previous chamber studies.

SECTION 1
INTRODUCTION
An assessment of human exposure to indoor air contaminants and the
relationship of this exposure to adverse health effects has become an
active area of study over the past several years. Research efforts have
been directed toward evaluating emissions from indoor sources (1-6),
physically and chemically characterizing indoor pollutants (4, 7-10),
modeling indoor pollution exposure (11-13), and applying methods of
pollutant mitigation (14,15). The presence of indoor air contaminants and
exposure is of most concern to persons spending from 70 to 90% of their
time indoors (4). Further, the quality of indoor air is becoming
increasingly problematical as measures to conserve energy, such as reducing
ventilation rates, are instituted in buildings.
Previous research efforts related to indoor air quality have concen-
trated on several criteria pollutants (CO, NO^, particulates) and several
uniquely indoor pollutants (radon, formaldehyde, asbestos) in private
residences (16). Large numbers of hazardous air pollutants or noncriteria
compounds (solvents, pesticides, PCBs, polynuclear aromatic compounds) that
may exist in buildings where large numbers of people spend much of their
time (schools, office buildings, nursing homes, and hospitals) have not
been investigated comprehensively. Only 11 mi ted data are available on
pollutant emission rates from building materials, furnishings, or main-
tenance supplies. This monitoring and analysis effort was undertaken to
answer some of these questions.
The objectives of this research were to monitor air in and around
public access buildings for a broad range of organic and inorganic
compounds; to measure emission rates of chemicals from building materials
as part of a chamber study; and to examine the relationships between chemi-
cals, building materials, and human activities.

SECTION 2
SUMMARY AND CONCLUSIONS
Air was monitored in and around a variety of public buildings where
occupants spend much of their time indoors. Then, in conjunction with the
monitoring effort, emission rates of chemicals from building materials used
in one of those same buildings were measured. Results of the emission
testing were compared to the field monitoring data and reported activities
within the buildings in an attempt to relate potential sources with
measured pollutant levels.
Chemicals measured included volatile organics, nitrosamines,
pesticides/PCBs, particulate mass, polynuclear aromatic hydrocarbons
(PNAs), metals, formaldehyde, radon, carbon monoxide, nitrogen dioxide and
asbestos. Six buildings were sampled: a new hospital, office, and nursing
home and an older office, office/school and nursing home. The new
buildings were monitored immediately (1-4 weeks) after construction and
again one or two times after occupancy. At each building, sampling was
performed at three indoor locations and a single outdoor location.
VOLATILE ORGANICS
Each sample for volatile organics was collected in triplicate using
different air volumes (10, 15, and 20 L). Quantitation analysis was then
performed for thirty (30) target compounds and the mean and % relative
standard deviation (% RSD) for each target were calculated for all of the
triplicate colocated samples. The mean concentration values were used for
all statistical analyses. Precision of the monitoring technique was
evaluated using the data for % RSD.
For the initial statistical analysis, the percentage of air samples
that had concentrations reported above the quantifiable limit was calcu-
lated for each target volatile. This statistic is referred to as percent
-------

detected and was calculated for Indoor and outdoor samples collected during
each field monitoring trip. Based on percent detected data each target
chemical was placed In one of four categories depending upon frequency of
occurrence. Most of the ubiquitous volatile organlcs were aromatic hydro-
carbons such as benzene, the xylenes, ethyl benzene, and some of the
trlmethylbenzenes; 1,1,1-trlchloroethane was also ubiquitous. Frequently-
occurring target compounds detected more often Indoors Included the
remainder of the aromatic hydrocarbons, all of the target aliphatic
compounds, the two oxygenated compounds and several chlorinated organics.
Seven halogenated organlcs fell Into the category "rarely detected".
Mean Indoor and outdoor concentrations for target volatlles during each
field monitoring trip are given 1n Tables 1 and 2, respectively. These
data are summarized by compound class 1n Table 3 and show several
Interesting trends:
1. The new buildings showed very high total levels of volatile
organics Immediately after construction (trip 1). Levels decreased
dramatically during subsequent field monitoring trips. An
exception to this trend was the new hospital; however, this
building was first monitored eight months after completion and,
presumably during this time, the outgassing of volatile organlcs
from new building materials was no longer a significant source of
indoor pollution.
2. The major Indoor contaminants in the new buildings monitored
immediately after construction were the aliphatic organlcs. For
both the new nursing home and the office, target compounds in this
class accounted for greater than 60% of the total mass of volatile
material quantltated. Levels of the aliphatic hydrocarbons in
existing buildings were quite low, while mean outdoor concentra-
tions were below the quantifiable limit in all cases.
3. Although the aromatic hydrocarbons were ubiquitous, they were also
found 1n highest concentrations at the new btiUd1ng$ Immediately
after construction. As shown 1n Table 3, th« first trip to the new
nursing home and the new office were the only trips where mean
indoor/outdoor concentration ratios were greater than five. Again
levels decreased substantially by the second monitoring trip to
each of these buildings.

4. Mean Indoor concentrations for chlorinated hydrocarbons were
highest for the existing office building. Presumably, Indoor
concentrations resulted from the use of solvent based office
materials. Elevated levels of chlorinated hydrocarbons were also
found during the third trip to the hospital and the trip to the
office/school.
5. There appeared to be no discernible trend for the oxygenated
compounds although they were detected most often 1n the office
buildings.
NITROSAMINES
N-Nitrosomorphol1ne was detected at all Indoor locations at the
existing office. Mean concentrations ranged from 0.20 to 0.32 ng/m3.
Nitrosamlnes were not detected 1n any other samples.
PESTICIDES/PCBs
Only low concentrations «20 ng/m3) of pesticides and PCBs were found
during field monitoring. This 1s not surprising since these target chemi-
cals had not been applied In the monitored buildings. Two exceptions can
be noted here. First, although chlorpyrlfos was applied 1n several
buildings, 1t was not recovered from field controls and could not be
quantitated. Second, malathlon was sprayed around the outside of the
existing nursing home during the third day of monitoring. The outdoors
sample collected during this period showed a malathlon concentration of 95
ng/m3. Only trace levels (20 ng/m3) were detected Indoors for the same
period.
INHALABLE (IP) AND RESPIRABLE (RP) PARTICULATE MASS
Mean Indoor concentrations for Inhalable particulate (coarse) mass
ranged from 2.7 /*g/m3 at trip 1 to the new hospital to 20.4 /»g/m3 at the
second trip to the new hospital. Mean outdoor concentrations for IP ranged
from 7.1 to 22.4 /ig/m3. Mean Indoor concentrations for respirable particu-
late (fine) mass ranged from 2.7 to 47.0 /«g/m3. Mean outdoor levels for RP
were similar to Indoor levels ranging from 8.0 to 33.6 /
-------
8
POLYNUCLEAR AROMATIC HYDROCARBONS (PNAs)
Polynuclear aromatic hydrocarbons were not found in any samples. The
detection limit for the method was ~10 ng/m3 for individual PNAs. Results
indicate that much larger samples are required if measurements of PNAs are
desired for indoor locations where no specific sources exist such as wood
fireplaces or wood stoves.
METALS
Quantitative analysis was performed for nine metals (Al, Cr, Mn, Ni, As,
Se, Br, Cd, and Pb) during field monitoring. Percent detected values were
calculated for both indoor and outdoor air samples collected during each
trip. Results showed that nickel, bromine and lead were detected most
frequently, whereas aluminum, selenium, and cadmium were not detected in
any samples. Mean concentration levels of detected metals were generally
low «50 ng/m3). A comparison of indoor to outdoor mean concentrations
showed higher levels outdoors. Several exceptions were noted to this
trend: indoor concentrations for lead were higher than outdoor concen-
trations at both the new nursing home, trip 2, and the old office/school.
Higher indoor concentrations of arsenic were found at the new hospital,
trip 3.
FORMALDEHYDE
Measurable concentrations of formaldehyde were found more frequently
for indoor compared to outdoor samples. Trip 2 to the new office showed
highest indoor concentrations (>100 ppb).
RADON
Radon levels at all buildings were low «2 pCi/L). Only one sample,
collected at the new office, showed an elevated level at 4.11 pCi/L.
CARBON MONOXIDE AND NITROGEN DIOXIDE
CO and N02 were monitored only at the old office. No general trends
were noted in the data.
-------
ASBESTOS
Asbestos was detected in only one sample during field monitoring.
However, the level found in this sample (84 fibers/m3) was Identical to the
level found in one of the field blanks.
AIR EXCHANGE
Average air exchange rates for the monitored buildings were generally
in the range 0.3 to 0.6 air changes per h (ACH). The new hospital, trip 1,
had the highest exchange rate (0.94 changes/h), while trip 2 to the same
building had the lowest (0.14 ACH). Where differences between daytime and
nighttime air exchange rates existed, daytime rates were always higher.
EMISSION STUDY
The emission study was performed in two phases. In the first phase,
preliminary headspace experiments were performed by placing the material to
be tested in a small glass jar and measuring the volatile organics emitted
using a dynamic headspace technique. The experiments were specifically
designed to give a fast, relatively inexpensive evaluation of emissions
from a large variety (31) of building materials. During the second phase
of the study, nine materials with significant volatile emissions were
evaluated using more detailed chamber testing.
All emission testing was performed on materials used in the construc-
tion of a new single-story office building in Fairfax, Virginia. Most of
the 22 solid building materials tested were subsamples of the actual
materials used in construction. The remaining solid materials, plus the
nine solvent-based materials, were purchased from the manufacturer. Manu-
facturing lots were matched where feasible.
Tables 4 and 5 list both the materials tested and a summary of results
for the headspace experiments.
Generally, the solvent-based materials showed the highest emission
rates followed by the plastic and rubber materials, and carpeting.
Building materials such as wall board, ceiling tile, and cement block
showed few volatile organic emissions. Data from the chamber tests
verified these trends.
Results of field monitoring compared well with the results of both the
headspace and chamber experiments. For example, the aromatic hydrocarbons
that have the highest indoor air concentrations (ethylbenzene, m-ethyl-
toluene. and 1.2,4-trimethylbenzene) generally show highest emission rates

from all of the building materials. High emission rates for the n-alkanes
were found for many of the Interior materials Including the carpet,
linoleum tile, all of the plastic materials and the solvent materials such
as adheslves, paint, and caulk. All of these materials could contribute to
the high Indoor air concentrations of n-alkanes found 1n the office.
Particle board was probably the major contributor of a-pinene. Finally, at
the time monitoring was being performed, vinyl cove molding and cove
adhesive were being applied throughout the building. It is likely these
materials were major contributors to 1,1,1-trichloroethane, ethylbenzene,
and the xylenes found in the air samples.

SECTION 3
RECOMMENDATIONS
As a result of this Indoor Air Study, several recommendations can be
made about the design and implementation of future studies. Recommenda-
tions on sampling and analysis have also been included.
1. This study was intended to serve as a broad survey for monitoring a
variety of organic and inorganic chemicals in public access
buildings. Of necessity, this study monitored several different
building types with diverse environments within a building. It is
recommended that for future studies, hypotheses be formulated,
(i.e., levels of organic pollutants are high in rooms containing
office equipment), then the buildings and locations in the
building, pollutants, and monitoring strategies selected to test
these hypotheses.
2. Since results for volatile organics demonstrated both a large
number and high concentrations of volatile organic compounds
present in the indoor environment, future study should be designed
to also demonstrate health effects directly resulting from indoor
air pollution. Methodology for evaluating health effects of
complex mixtures of organic compounds should be developed and
tested.
3. Results of this study demonstrated that in many cases indoor pollu-
tion resulted from activity patterns and product use. Therefore,
more in-depth and accurate information should be collected on
specific activities and potential sources for chemicals. In
addition, chamber studies should continue to characterize potential
sources of indoor pollutants.
4. Simple, reliable methods still need to be developed for both inte-

cumbersome or Inaccurate. Many of the other methods, Including
those used for CO and N02, are noisy and place a high burden on the
building occupants. Other methods, such as those for PNAs and
metals, often did not have sufficiently low detection limits for
monitoring Indoor levels.
Mitigation methods should be developed for pollutants that are
found at unacceptably high levels.

SECTION 4
SAMPLING AND SAMPLE PREPARATION
INTRODUCTION
The major objective of the field portion of this study was to monitor
the air in and around public access buildings for a broad range of organic
and inorganic compounds. To accomplish this, three building types were
studied including offices, hospitals, and nursing homes. For this
project, EPA identified six buildings for field monitoring, including at
least one building from each category. New buildings were visited after
construction and several months after occupancy. Existing buildings were
visited only once.
The thirteen groups of chemicals or parameters monitored during this
research program are listed in Table 6. Sampling and analytical methods
and monitoring requirements are also summarized. For the purposes of
sampling and analysis, several of these groups were combined as indicated
on the table. Specifically, procedures for the analysis of volatile
organics using Tenax GC as a solid sorbent were applied to both Group I and
II chemicals. Table 7 outlines the specific sampling requirements for each
parameter in each building, including the planned number of locations per
building, samples per day, monitoring days per trip, and trips per
building. In all facilities, an outdoor location placed directly at the
air intake was monitored. The indoor locations were selected on-site to
represent a variety of indoor environments. All monitoring employed fixed-
site stations. Samples were collected for 12 or 24-hour periods in either
the morning or evening. Table 8 lists the buildings monitored, sampling
locations within each building, and monitoring dates.
All samples were collected using the protocols described in the Draft
Work Plan, Part II: Analytical Protocols (17). In this section, details of
sample preparation and collection for each chemical or physical parameter
will be given.

SAMPLING METHODS 26
Sampling Unit
Descr1pt1on--
To Implement the above sampling design, a minimum of eleven air samples
had to be collected at each location during each time period. On past
research projects, samples of this type were collected by pulling air
through the sorbent or filter using Individual sampling pumps. For this
project, we designed a compact sampling unit with a single vacuum pump
capable of simultaneously collecting up to sixteen different samples at
fixed measurable flow rates.
The sampling unit was intended to overcome several problems associated
with individual pumps. First, the number of individual pumps needed would
be very large. Second, the logistics of Individually measuring flow rates
for more than eleven pumps at four locations during each sampling period
would greatly increase the workload in the field and would require
additional personnel. Third, when working 1n buildings such as offices or
hospitals, the area made available for the sampling equipment is often
small. Hence, a single compact unit that could replace a large number of
individual sampling pumps offered more flexibility in selecting monitoring
locations. Finally, the use of a single unit would significantly decrease
the noise at each monitoring location.
The compact sampling unit consisted of two 12 x 8 x 11 Inch metal boxes
with eight flow meters. A Thomas double-diaphragm vacuum pump was housed
1n a separate, vented metal box. A single vacuum line entered each box and
was split through a manifold Into seven flow meters. The flow rate for
each cartridge was controlled by a needle valve and was read directly from
the calibrated flow meter. Each flow meter was individually calibrated
prior to the beginning of a sampling trip. In addition, a single vacuum
line that supplied a DuPont P2500 constant flow sampler in series with a
flow meter was installed 1n each box to collect metal and asbestos samples.
The use of a constant flow sampler was required for these samples since the
0.3 urn Nucleopore filters could easily become embedded with particulate to
give a significant Increase 1n back pressure, and hence, drop in flow.
Table 9 summarizes Information on the samples collected with the
compact sampler and the flow rates used.

Validation--
Once the sampling units were constructed, several validation experi-
ments were performed to show that
the back pressure caused by several sorbent cartridges attached to
the sampling unit would not cause fluctuations 1n flow rate or
calibration of the flow meters, and that
the flow meters were accurate and reproducible.
In the first experiment, the effect of a sampling cartridge on flow
rate was evaluated. For testing, an empty glass cartridge (1 x 30 cm) was
connected to one of the sampling ports, the rotometer was set to 22 and the
flow rate measured. The empty cartridge was then replaced with a similar
cartridge containing 10 g of molecular sieve, the sorbent for formaldehyde
collection. The rotometer was again set to 22 and the flow rate measured.
During testing, the flow rate through the molecular sieve did not change
compared to an equal size, but empty cartridge.
During a second experiment, precision of the flow meters was evaluated
by measuring the variability in flow rates over a 14-hour period. For each
measurement, the rotometer was adjusted to 20 and triplicate flow measure-
ments were taken using a bubble flow meter. No sampling cartridge was used
during the measurements. Results showed no variability in flow rate.
Prior to field monitoring, all rotometers on each unit were calibrated
using Tylan mass flow meters. During the first field monitoring trip, a
quality assurance check of the rotometers' calibration was performed while
1n the field. Table 10 compares the sample flow as indicated on the roto-
meters versus the flow as measured with a bubble flow meter. Both measure-
ments were taken with the sample cartridges installed.
Volatile Organics
Collection Method--
Each sample for volatile organics was collected in triplicate using
distributed air volumes. Volatile organic compounds were collected from
air samples by passing the air through a glass sampling cartridge (10 x 1.5
cm I.D.) containing 6 cm of 40/60 mesh Tenax. Flow rates were adjusted to
approximately 15, 20, and 30 mL/min. This gave sample volumes of 10, 15,
and 20 L of air for each of the six 12-hour collection periods.

Sample sizes were selected so that the "breakthrough volume" for any of
the target compounds would not be exceeded for the low volume (10 L)
sample. Table 11 gives "breakthrough volumes" for each target volatile
(18-20). The "breakthrough volume" 1s defined as that point at which 50%
of a discrete sample Introduced Into the cartridge 1s lost. Chloroform was
not collected using Tenax GC because of its low "breakthrough volume" (9 L
at 70°F). Rather, it was treated as a miscellaneous volatile.
Preparation of Sampling Materials--
Tenax GC used during previous field monitoring studies was recycled for
use on this project. Prior to use, the Tenax GC was extracted in a Soxhlet
apparatus for 24 h first with methanol, then with n-pentane. After extrac-
tion, the Tenax GC was dried under a nitrogen atmosphere for 24 h, and then
in a vacuum oven at 100°C for 24 h at 28 Inches of water. The Tenax was
sieved to provide a 40/60 particle size range then packed into glass
sampling cartridges. After packing, each cartridge was desorbed at 270°C
with a purified helium purge for 5 h.
Twenty-four hours after the final desorption step, 10% of the Tenax GC
cartridges were analyzed by thermal desorption/GC/FID to determine back-
ground contamination. If the background contamination exceeded specified
limits, the entire batch of cartridges was redesorbed and tested for
contamination again. Only when cleanliness criteria were met could the
cartridges be used for field sampling. Standard operating procedures were
used for preparation of Tenax for field sampling.
Preparation of Quality Control Supplies-
Sets of quality control (QC) samples each consisting of one blank and
one spiked control were prepared for each field monitoring trip. The spiked
controls were loaded using a flask evaporation system as shown in Figure 1
(21). An aliquot (1 /jL) of the standard solution prepared in methanol was
Injected through the septum of the heated loading tube (250°C). The
vaporized components were swept onto the Tenax GC cartridge with purified
He at a rate of 60 mL/m1n for 15 m1n (total He 0.9 L). Because of the low
breakthrough volume for methanol (0.8 L at 70°C), the majority of it passes
through the cartridge. Compounds and the amount loaded on each cartridge
are shown in Table 12.

The number of QC samples scheduled and exposed for each trip is shown
1n Table 13.
Nitrosamines
Collection Method—
Nitrosamines 1n air samples were collected by passing air through a
glass sampling cartridge containing Thermosorb/N (ThermoElectron
Corporation). Flow rates were adjusted to approximately 100 mL/min. This
gave a sample volume of 72 L for each of the six 12-hour collection
periods.
Studies performed with this sorbent (22) have shown that breakthrough
volumes are greater than 100 L for both dimethylnitrosamine and nitroso-
morpholine. In addition, it has been demonstrated that the collection
technique using Thermosorb/N 1s free from artifactual nitrosamine
formation.
Preparation of Sampling Materials-
Sampling cartridges were used directly as supplied from the Thermo-
Electron Corporation.
Preparation of Quality Control Samples--
Sets of QC samples each consisting of one blank and one spiked control
were prepared. Controls were loaded by directly injecting 1 pi of a
standard nitrosamine solution Into the inlet side of the sampling
cartridge. Standard solutions were obtained from the ThermoElectron
Corporation. Each spiked control contained 97 ng of dimethylnltrosamine
and 110 ng of nitrosomorphollne.
The number of QC samples scheduled and exposed for each trip is shown
1n Table 13.
Miscellaneous Volatiles
Collection Method-

sample volume of 18 L of air for each of the six 12-hour collection
periods.
Acrylonitrile was collected using a separate 150 mg charcoal tube in an
Identical manner. A separate tube for acrylonitrile was required to
accommodate different desorptlon conditions. After sampling, the solid
sorbents were stored at -20°C prior to analysis.
Preparation of Sampling Materials-
Sampling cartridges were used directly as supplied from SKC, Inc.
Preparation of Quality Control Samples--
Sets of QC samples each consisting of one blank and one spiked control
were prepared. The spiked controls were prepared by loading known amounts
of the analytes onto newly-opened charcoal sampling tubes. The blanks were
simply tubes to be opened at the appropriate time (in the field at the time
of sampling for field blanks and in the lab at the time of analysis for the
lab blanks).
Compounds normally in the liquid state were loaded onto the tubes using
the flash evaporation technique described previously. Gaseous compounds
were loaded onto the tubes using the same apparatus except a known quantity
of gas at a known concentration was injected using a gas-tight syringe.
The loaded tubes were capped and stored in a freezer after loading was
completed.
The analytes were divided into two groups for QC sample preparation:
the gases (vinyl chloride and ethylene oxide), and the liquids (acrylo-
nitrile, vinylidene chloride, chloroform, 2-propanone, 2-butanone,
n-propanol, n-butanolphenol and acrolein). First, vinyl chloride was
loaded onto a set of tubes. Next, a mixture of the liquids exclusive of
acrylonitrile was loaded onto a set of tubes. Finally, acrylonitrile in
C$2 was loaded onto an independent set of tubes. Since a reliable source
of ethylene oxide could not be found, QC samples containing this material
were not prepared. The quantities loaded (Table 14) were 20 to 100 times
the estimated detection limits.
The number of QC samples scheduled and exposed for each trip is shown

Pesticides and PCBs
Collection Method—
Pest1c1des/PCBs were collected from air samples by passing the air
through a glass sampling cartridge containing a 22 mm x 7.6 cm cylindrical
polyurethane foam (PUF) plug. Flow rates were adjusted to -1.3 L/min.
This gave sample volumes of 936 L for each 12-hour sampling period.
Research performed by Lewis et al. (24,25) has demonstrated that collection
efficiency for all of the target pesticides/PCBs, except Dichlorvos, should
be greater than 84%. Collection efficiency for Dichlorvos should be
72 + 13%. Since breakthrough from the PUF 1s the major cause of loss for
this pesticide, larger sampling volumes were not used. Immediately after
collection, the PUF plugs were removed from the glass sampling cartridges
and sealed in glass jars with Teflon-lined screw caps. The glass jars were
placed in air-tight, uncoated paint cans for storage 1n the field.
Preparation of Sampling Materials--
Polyurethane foam (PUF) plugs for the collection of pesticides and PCBs
were prepared from open-cell polyurethane foam, density 0.022 g/cm (Olympia
Products, Greensboro, NC). Sheets of PUF were cut into 22 mm x 7.6 cm
cylinders with a 7/8" arch punch and jig. The plugs were Soxhlet-extracted
for 24 hours in acetone followed by a 24-hour extraction in hexane. During
Soxhlet extraction, the Soxhlet reservoir was wrapped with aluminum foil to
prevent photodecomposition of the foam. After extraction the plugs were
dried in a vacuum oven at ambient temperature. Once dry the plugs were
placed in 8-dram glass vials, capped, and stored in uncoated, aluminum
paint cans until sampling.
Preparation of Quality Control Samples--
Sets of QC samples each consisting of one blank and one spiked control
were prepared. Controls were loaded by directly Injecting 1 /*L of a
standard pesticide/PCB solution prepared in hexane into the PUF plugs.
Aroclor 1254 served as the PCB standard. Spiked controls were fortified
with target pesticides/PCBs at the levels listed in Table 15.
The number of QC samples scheduled and exposed for each trip is shown
1n Table 13.

Inhalable and Resplrable Particulates and Polynuclear Aromatic Hydrocarbons
(PNAs)'
Collection Method--
A National Bureau of Standards (NBS) Portable Ambient Participate
Sampler was used to collect inhalable or coarse (3-15 /jm) and respirable or
fine (£3 pm) particulates and PNAs in air samples. This sampler employed
two filters in series to collect the particulates. An 8.0 pm Nucleopore
filter was used for coarse particle collection, a 3 pm Ghia Zeflour Teflon
fiber filter for fine particle collection. During sampling, flow rates
were adjusted to ~6 L/min for a total sample volume of 8.6 m3 for each
24-hour sampling period. After collection, filters assemblies were capped.
Samples were stored at room temperature wrapped in aluminum foil.
The NBS sampler was designed by the National Bureau of Standards for
EPA/RTP and supplied to RTI by EPA. Details of the design, testing, and
operation of this sampler are contained in the NBS project report, which is
available from NTIS as document number NBSIR 82-2861 (26).
This sampler provided several advantages for indoor air sampling over
the more common d1chotomoi:s sampler. Most importantly, it was a small,
compact, quiet sampler which is preferable for sampling indoor environments
without interrupting normal activities.
Preparation of Sampling Materials--
Seven National Bureau of Standards (NBS) Portable Ambient Particulate
Samplers were obtained from the EPA. The units were modified allowing them
to operate on an external DC power supply rather than on the NiCd batteries
specified.
All filters used during sampling were allowed to equilibrate at 70 +
2°F and 50 + 2% relative humidity (+2°C) for 24 hours. The filters were
then weighed using a Mettler Balance with certified accuracy to 0.001 pg.
All filters were exposed to an ionizing source immediately prior to
weighing to reduce static charge and improve reproducibility of filter
weights. Weighed filters were then assembled into two-stage filter
holders.
42
-------
Preparation of Quality Control Samples 43
Single filter assemblies containing both the Inhalable and resplrable
partlculate filters were prepared as blank samples. The number of QC
samples scheduled and exposed for each trip 1s shown 1n Table 13.
Metals
Collection Method-
Air was sampled using a DuPont P2500 monitoring pump at a flow rate of
approximately 1 L/min. For a 24-hour collection period, this provided a
total sample volume of 1.4 m^. Ambient air particulate from the sampled
air was collected on aerosol-grade, 0.3 pm Nucleopore polycarbonate
filters. After collection, the filters were carefully removed from the
holders and placed upright in a 35 mm plastic petri dish for storage and
transportation.
Preparation of Sampling Materials--
Aerosol -grade, polycarbonate filters were used as supplied by the
Nucleopore Corporation.
Preparation of Quality Control Samples--
Unexposed filters placed in clean 4-cm plastic petri dishes served as
blank samples. No spiked control samples were prepared. The number of QC
samples scheduled and exposed for each trip is shown in Table 13.
Formaldehyde
Collection Method-
Formaldehyde was collected from air samples by passing the air through
a 9 mm I.D. x 30 cm glass tube containing 10 g of pretreated molecular
sieve powder. Flow rates were adjusted to ~30 mL/min to provide a 60 L
sample for each 24-hour period. Exposed sieve material was emptied from
the glass holder and stored in sealed glass bottles at room temperature
until analysis.
-------
Preparation of Sampling Material— 44
To prepare sample cartridges, molecular sieve (-1 kg) was washed in
deionlzed water to remove fines. It was next filtered under a vacuum
through Whatman 12 filter paper and dried for 24 hours in a vacuum oven at
180*C. Once dried, 10 gram allquots were transferred to 20 ml serum
bottles and baked 1n an oven at 200*C for 20 minutes. The bottles were
removed and sealed while hot with sleeve-type rubber stoppers. The sieve
was shipped to the field 1n these bottles. Immediately prior to sampling
the bottle was opened, the sieve transferred to an empty glass cartridge
and the cartridge attached to the sampling unit.
Preparation of Quality Control Samples-
Sets of QC samples each consisting of one blank and one spiked control
were prepared for each field monitoring trip.
Spiked controls were fortified with formaldehyde using a flash evapora-
tion system. For spiking, 10 g of prepared molecular sieve was transferred
from the 20 ml serum bottle into a 1 cm x 30 cm borosilicate glass tube.
The tube was placed Into a fitting on the flash evaporator system and the
He carrier gas flow was adjusted to 60 mL/min. A 2.5 pi injection of an
aqueous formaldehyde solution was injected into the flash evaporator system
and loaded onto the molecular sieve for two minutes. Throughout the study
controls were spiked at levels ranging from 3.5 to 21 ^g per cartridge.
The number of QC samples scheduled and exposed for each trip is shown
in Table 13.
Validation of the Formaldehyde Protocol —
An experiment was performed to verify that formaldehyde in a sample
would not "breakthrough" the molecular sieve cartridge under field
conditions. During testing, spiked and unspiked molecular sieve cartridges
were prepared. Three spiked cartridges were each placed in series with
unspiked backup cartridges. The cartridges were then placed onto a
sampling unit and air was pulled through the cartridges at 30 mL/min for 24
hours (20*C, 50 + 5% RH). Each cartridge was analyzed for formaldehyde as
described in Section 6. Triplicate spiked and unspiked cartridges main-
tained with no air flow were analyzed at the same time. Formaldehyde did
not appear on the backup cartridge Indicating that breakthrough had not
-------
45
occurred. Average recoveries of 56 and 58% were achieved for spiked
exposed and unexposed cartridges, respectively, indicating no loss of
formaldehyde due to exposure and hence no significant breakthrough.
Radon
Collection Method--
Air was sampled for radon using Track-Etch^ SF integrating passive
radon monitors (Terradex Corporation). The monitors were placed on the
ceilings or upper door facings within the areas sampled. The monitors were
exposed for three months. They were then taken down, resealed in their
aluminum envelopes, and returned to the Terradex Corporation for analysis.
Preparation of Sampling Materials-
Radon monitors were used directly as provided by the Terradex
Corporation.
Preparation of QC Sets—
Unexposed monitors served as field and laboratory blanks. The number
of QC samples scheduled and exposed for each trip is shown in Table 13.
Air Exchange Measurements
Collection Method-
Air exchange measurements were conducted using sulfur hexafluoride
(SFs) as a tracer gas. Air samples were collected at discrete intervals
following release of the tracer into the building air supply duct(s).
Approximately 3 L of SFs for each 106 ft3 of building volume was
injected in the air supply system. A 0.5 to 1 hour delay between release
and sample collection allowed for distribution of the tracer into building
compartments. Sampling was performed using programmable syringe samplers
(Manufacturer Model DSI-12) that automatically collected 30 ml of air at
preselected time intervals. Samples were collected at 1, 3, 5, 7, 9 and 11
hours after tracer release.
After collection, syringes were sealed and stored at room temperature
until analysis.
-------
A fi
Preparation of Sampling Materials--
The DSI sequential syringe samplers were Inspected and repaired If
necessary prior to each trip. The samplers were used as specified by the
manufacturer.
Sulfur hexafluorlde was purchased 1n a gas cylinder from MG Scientific
Gases. The gas was checked for purity by GC/ECD analysis. No contaminants
were detected.
Preparation of Quality Control Samples-
No controls or blanks were prepared.
Carbon Monoxide
Collection Method—
Concentrations of carbon monoxide (CO) were monitored using a Bendix
Infrared CO analyzer. This analyzer was calibrated using compressed gas
cylinders at 0, 2, 5, 10, 20 and 30 ppm CO.
After installation at a sampling location, the analyzer was allowed to
warm up for 1 hour and then calibrated using the compressed gas cylinders.
Calibration gas from the cylinders was delivered to a manifold where the
analyzer sampled. The calibration manifold was used to ensure atmospheric
pressure that would simulate an ambient air sample. Multipoint calibra-
tions were conducted at the beginning of the monitoring period. Zero and
span tests were conducted daily to ensure that the multipoint calibration
remained accurate.
Data was copied on strip chart recorders. The multipoint calibrations
were then used to generate a calibration equation. The calibration
equation was a linear relationship in the form y=M(x)+b, where y=[CO],
M=slope, x=recorder response and b=intercept. Data was reduced to hourly
averages and tabulated on coding forms for computer entry.
Preparation of Sampling Materials--
The Bendix CO monitors were provided by EPA (RTP). Before the start of
monitoring, the analyzers were tested for proper operation, Including
linearity.
-------
47
Calibration gas was received and certified by RTI Ambient A1r Audit
Center (AAAC) prior to use. Zero air was also certified by the laboratory.
Preparation of Quality Control Samples--
No QC samples were prepared.
Nitrogen Dioxide
Collection Method-
Nitrogen dioxide was measured 1n the air using Bendix continuous chemi-
luminescent monitors. After installation at a sampling location, the
analyzers were allowed to warm up (4 to 6 hours) and then calibrated using
the gas-phase tltratlon method. This was performed by simultaneously cali-
brating the NO and NOX channels and then calibrating the N0£ channel. The
NO and NOX calibration Is conducted by dilution of the compressed gas
nitric oxide cylinder. The N0£ channel Is calibrated by adding ozone to
the highest NO-NOX calibration point. Ozone reacting with NO produces N02,
which is equal to the change 1n analyzer NO response. The efficiency of
the catalytic converter 1s based upon the analyzer's NOX response during
the production of N02.
Multipoint calibrations were conducted at the beginning of the moni-
toring period. Zero and span tests were conducted dally to ensure that the
analyzers multipoint calibration remained accurate. All data were recorded
on strip chart recorders.
Preparation of Sampling Materials—
Bendix NOX analyzers were obtained from EPA/RTP. Leeds and Northrup
strip chart recorders were also obtained from EPA/RTP. The calibration
system used was RTI's Gas-Phase Titration assembly consisting of a nitrogen
oxides-free, zero air system; flow controllers to maintain constant and
predictable flows; an NBS traceable compressed gas cylinder of nitric oxide
and an NBS traceable, soap film, flow meter. This complete gas-phase
tltratlon system was verified for proper operation 1n the RTI Ambient Air
Audit Center (AAAC) prior to use. The AAAC was operated with NBS traceable
standards and EPA approved procedures. Before the start of monitoring, the
analyzers were tested for proper operation, Including linearity and
converter efficiency.
-------
48
Preparation of Quality Control Samples--
No QC samples were prepared.
Asbestos
Collection Method-
Samples for asbestos analysis were collected on Nucleopore, polycar-
bonate filters (37 mm, 0.2 p] backed with a cellulose ester filter (0.87 /;)
to enhance uniformity of particulate collection. These filters were placed
in a three-piece plastic, sampling cassette over a cellulose support pad.
At the beginning of each sampling period, the filter cassette was
attached to a DuPont P2500 Constant Flow pump and the flow rate adjusted to
~2 L/min. This provided a total sample volume of «-4.6 m3 over a 72-hour
sampling period.
Samples were stored in the cassette holder until analysis.
Preparation of Sampling Materials—
Filters were assembled in cassettes inside a laminar flow laboratory
hood equipped with a high efficiency particulate arrestant (HEPA) air
filter to prevent contamination with ambient fibrous particles. Cassettes,
with filters and support pads in place, were sealed with shrink bands and
numbered with an indelible marker.
Preparation of Quality Control Samples--
Unexposed filter cassettes served as field and laboratory blanks. No
spiked controls were prepared. The number of QC samples scheduled and
exposed for each trip is given in Table 13.
Meteorological Measurements
Collection Method--
Meteorological measurements made at each site consisted of wind speed,
wind direction, temperature and relative humidity. These measurements were
made using a Meteorology Research Incorporated Metric Mechanical Weather
Station. The station was placed atop a 2-meter portable tower, was located
1n the area of optimum exposure and was oriented with a magnetic compass.
Wind direction was sensed by a ball bearing-mounted, balanced, single
blade aluminum vane with nose damping. The wind speed was measured by a
-------
49
cup anemometer employing three conical aluminum cups. The temperature
sensor was a shielded spiral coll bimetal element. All Information was
recorded on a strip chart recorder housed within the weather station. (See
Appendix A for a summary of weather conditions.)
In addition to the meteorological data collected, constant temperature
and relative humidity measurements were made at two Interior locations
using Cole-Palmer Hydrothermographs and a psychrometer. (See Appendix B
for a summary of Indoor temperature and humidity conditions.)

SECTION 5
BUILDING SURVEY
OVERVIEW
Data Collection
An important part of this research project was to collect information
on ancillary variables that could effect the indoor air quality of the
buildings in the field monitoring study. To this end, data on building
structure, building material composition, cleaning and maintenance
materials in use, heating, ventilating and air conditioning operating para-
meters, and other related information were collected by Research Triangle
Institute (RTI) and the National Institute of Building Sciences (NIBS).
These activities were initiated through preliminary meetings between
RTI and EPA project staff to determine what data should be collected. Data
collection instruments were drafted and circulated. A meeting attended by
RTI, EPA, and NIBS project staff was then held to review the instruments
and to determine what information could be collected by RTI and what could
more appropriately be provided by NIBS. As a result of that meeting the
following items were agreed upon.
1. The three inside and one outside monitoring locations for each
building would be selected by EPA and RTI personnel; however, NIBS
personnel would review the interior locations selected to check
that they are served by the one outside air intake to be monitored.
2. The drawings and specifications for each building to be monitored
would be provided to NIBS by EPA/RTP.
3. During the building operation analysis, the NIBS contractor would
note readily identifiable materials containing asbestos.
4. It was requested that NIBS provide probable air exchange rates for
the spaces to be monitored (based on the information shown on the
drawings) and include this information in the building operation
analysis.

5. After considerable discussion about the draft building question-
naire, 1t was agreed that 1t would be more efficient to obtain much
of the needed Information from the drawings and specifications for
each building and confirm this Information at the site as part of
the Building Operation Analysis, than to conduct a questionnaire-
type survey. As a result, the NIBS representatives agreed to
prepare a narrative report for each building providing the
following Information:
- size of building,
- size of monitoring area
- floor budget
- mechanical ventilation system design,
- Interior building materials,
- exterior building materials,
- general construction,
- interior finishes.
6. RTI would provide the remaining information using the questionnaire
format.
Based on this meeting, a second draft of RTI's survey instruments was
prepared and the review process repeated. Based on the final review, four
final data collection documents were prepared. These forms are more
completely described in subsequent paragraphs.
The next phase of the data collection activity was the identification
of the appropriate personnel to be interviewed at the monitoring sites. If
personnel were Identified prior to the site visit, initial telephone
contacts were made to Identify the types of data to be collected. These
calls were supplemented by contacts from the EPA project staff to facili-
tate the ease of data acquisition. When the project team arrived on site,
data collection began with the final identification of the monitoring
locations. This selection was in some cases influenced by data reviewed
and interviews conducted during the first hours on-site. Once the loca-
tions were selected, equipment was placed, and the formal interview process
begun. With one exception, as noted below, all forms were completed at the
beginning of the study period for the particular location. The remaining
form was used to record data on an ongoing basis and was completed during
the start and finish of each Individual monitoring period. The remaining
sections of this chapter describe the data collection instruments and the
data collected using them for each of the six buildings visited as part of
this research study.

Data Collection Instruments
Using the Iterative review process described previously, four data
collection Instruments were developed by RTI. These forms were used to
collect different data, using various sources, and were completed at
varying times throughout the monitoring period. The four forms Included
the General Area Description, the Building Questionnaire, the Monitor Loca-
tion Questionnaire, and the General Interview Information form. Each is
described 1n more detail 1n the following paragraphs.
NIBS provided a written report for each building (except the old
office) describing the size, general construction, building materials,
interior finishes, and ventilation system. A copy of these reports is
given in Appendix C.
General Area Description—
The purpose of this form was to record general data on the area
surrounding the building being monitored. The area of interest was an
elliptical area of approximately one-half mile radius, with an additional
half mile up-wind inclusion. Data descriptive of the area Included amounts
of open land, water, hills and other Impediments to wind flow, and descrip-
tions of the surrounding structures or land on each side of the building.
These surrounding areas were described in terms of potential effects on the
monitoring site and included data on sources of chemicals, traffic volume,
and any unusual occurrences in the Immediate past few days. This form was
completed once at the beginning of the study period for the particular
site.
Building Questionnaire—
This document, also completed once at the beginning of the study
period, was used to record data describing the structure containing the
individual monitoring locations. The document contained five sections,
each with a differing focus. The first section described the general char-
acteristics of the structure, including usage, age and recent renovations,
size and volume, building materials, attached garages, and water supply.
The second section described the Interior of the structure 1n terms of
Internal construction characteristics and materials and the heating,
ventilation, and air conditioning systems including the normal climate
-------
53
maintained. The third section focused on building modifications,
especially those affecting building tightness. The fourth section listed
data on Internal maintenance and decor by describing the Internal
furnishings and use of pesticides and cleaning products. The types of
products and the frequency of application were detailed. The final section
described any external Influences, such as pressure gradients, unusual
local events, and any known outdoor air quality Information. In addition,
data on local meteorology, both micro and macro, were recorded in this
section.
Monitor Location Questionnaire—
This form collected information about the specific locations where
monitoring devices were placed and was completed repetitively for each day
that monitoring was undertaken. Administration of some parts of the
Building Questionnaire was also repeated to record data on any major struc-
tural improvements or significant modifications that might influence the
indoor air quality. The Monitor Location Questionnaire included a general
description of the location of the monitors, focusing on the use of the
area, as well as its size, insulation, and the presence of products which
might affect air quality through the direct introduction of a chemical or
through the out-gassing of various products as the materials aged.
Products of particular Interest included foam insulation, polyurethane,
plywood, plastics, carpeting, wall coverings, and pesticides. Data were
also collected on the presence and use of gas cooking stoves, gas or kero-
sene space heaters, free standing stoves or fireplaces, clothes dryers, and
humidifiers. Information on air filters or particle scavengers and
vacuuming and dusting regimens was collected and supplemented with data on
the amounts and frequency of use of household products, including cleaning
supplies, aerosol products, and housekeeping products. The final section
of this form listed variable data specific to the period being monitored.
These data included the dates and times of monitoring, the inside and
outside meteorology (temperature, humidity, wind speed and direction, and
barometric pressure). Additional information on occupancy levels, smoking
status, and the presence of pets or pest strips were collected, as was an
indication of the presence of open windows. Specific descriptions of any
-------
54
unusual products 1n use 1n the immediate area were recorded, as were the
details of any unusual occurrence during the monitoring period.
General Interview Information--
This form was used to collect information about the data collection
process. It identified the persons from whom data were collected and
recorded addresses and phone numbers in case recontact became necessary.
The form also provided a final place in which to record any unusual circum-
stances that occurred and might have had any affect on the data collected
and its subsequent analysis.
RESULTS
This section describes each of the buildings visited, including
specific information about the site 1n general, the building monitored, and
the specific locations of the monitoring instrumentation. The data
presented are a summary of the data collected on the various questionnaires
described above. This Information was supplemented by the data provided by
the National Institute of Building Sciences.
Hospital (New)
Trip 1—
General Area Description—This site, monitored during July 1984, was
the new hospital building of a Veterans Administration (VA) Hospital and
Domiciliary complex located near Martinsburg, West Virginia. The complex
was located in a generally rural setting in rolling countryside. Over 60%
of the immediate surrounding Vand was open and undeveloped with no obstruc-
tions to wind flow. Adjacent to the building on all sides were parking
areas with interspersed grassy lawns. Located in the same site as the
hospital were the domiciliary unit, the nursing home, and the original
hospital complex, built in the 1940s. Farm land located behind the
facility presented the only known suspected source of chemicals in the
surrounding area. It was reported that there had been observed aerial
spraying, presumably to supplement the normal application of herbicides or
pesticides. Traffic flow in the immediate vicinity was limited to local
hospital traffic. There were no freeways in the area; the main state high-
way, with an average traffic flow of 200 cars per hour, was locate
approximately one-third of a mile from the front of the hospital. At the
-------
55
site Itself, there had been a recent application of 300 gallons of a
Malathion mixture sprayed on trees and shrubs around the facility. The
application had been so recent that a distinct odor was present.
Building Description—This building was a recently completed structure
being prepared for use as a hospital facility 1n the VA complex. The total
building volume was >580,000 square feet. The structure, built 1n 1983 and
1984, uses water obtained from a private well, treated in a private on-
site facility, and stored in an on-s1te tank. Radiant heaters in stair-
wells were used to supplement the main heating system, which used only #2
fuel oil. Electric kitchen appliances were supplemented with steam
appliances. No secondary sources of air conditioning were present; however,
secondary ventilation was supplied by exhaust systems in the kitchen and
bathrooms. Heating systems were designed to maintain a 72'F temperature
during the winter, and 78*F temperature during the summer, with a standard
60% relative humidity.
Since the building was brand new and unoccupied, there were no Internal
maintenance changes 1n the facility. There were no reported unusual
occurrences 1n the building or on-s1te during the seven days prior to
monitoring. The building construction was finished approximately eight
months before sampling began, but only the security station and engineering
offices had been occupied.
All monitoring locations were on the fifth floor. Figure 2 shows the
monitoring area with each location marked.
Monitoring Location #1, Visitors' Lounge--Th1s location was an
irregularly-shaped room to be used as a visitors' lounge (Room 5-A-103).
Located on the fifth floor, approximately seventy feet above grade, the
room's major dimensions were 30 feet by 35 feet, with eight-foot hanging
ceilings. There were no opening windows, only one Interior door, and
ventilation was supplied by three air supplies and two returns rated at 600
cfm and 510 cfm, respectively.
Furnishings Included thirty new chairs, each containing a foam cushion,
plastic picture covers and light covers with a total surface area of
approximately 90-100 square feet. There were also five wooden tables. All
walls of the room were painted with the exception of one 200 square foot
wall covered with wall paper. The floors were covered with carpeting. The

between two corridors and will be used as a nurses' station (Room 5-A-llb).
It was approximately 400 square feet in area, under eight-foot ceilings and
was located on the fifth floor between two interior corridors. Ventilation
was provided by free mixing of air supplied by feeds in both corridors.
There were two returns located in the area.
The area contained approximately 2,000 square feet of formica-type
counter surface and trim. There were two foam stuffed chairs at the loca-
tion, as well as four garbage cans. The area also contained a terminal for
the air-powered tube transport system and the electrical, patient communi-
cation system.
All wall surfaces were painted, and carpeting was present on the
floors. The area was not yet occupied, but the bathrooms and hallway
floors were cleaned regularly.
No smoking was observed during the monitoring period.
Monitoring Location #3 - Patients' Room—This location was a rectan-
gular room to be used as a two-patient hospital room (Room 5-A-109).
Located on the fifth floor, the room encompassed 250 square feet plus 28
square feet in a wash alcove and bathroom. The room contained one openable
window and one interior door. Ventilation was provided by one 120 cfm air
supply and an exhaust in the bathroom. No smoking was observed during the
monitoring period.
Monitoring Location #4 - Roof—This location was on the roof, hospital
which was covered with a rubber mat and varying sized rock and gravel. The
site was not near any of the exhaust vents or air blowers.
Trip 2—
The second trip to the new hospital took place in October 1984. The
primary difference in the sampling site at this time versus the first trip
during July was that the hospital was occupied with staff and patients and
was fully operational. All sampling locations were identical to those
selected for the first trip.
-------
58
Location #1 was again assigned to Visitors' Lounge 5A. The lounge
contained a television which remained on during most of the daytime hours.
Patients, particularly smokers, occupied the lounge during each day. No
cleaning, housekeeping, or aerosol products were used during the monitoring
period. The adjacent stairwell was painted immediately before the start of
sample collection with a paint odor still present in the stairwell.
Location #2 was assigned to the nurses' station on the fifth floor.
The area was used for paperwork and as a drug dispensation area. Smoking
was not observed in the vicinity. "Hi-Torr" disinfectant was used at least
once each day when the floors were mopped. No other cleaning or aerosol
products were noted.
Location #3 was a room occupied by two patients at the time of
sampling. There was no smoking observed in this area. The floors were
mopped daily with "Hi-Torr" and LpH (glyolic acid, o-benzyl-p_-chlorophenol,
p_-tertiary amylphenol, and o-phenyl phenol). "Spray Buff", a wooden
cabinet cleaner containing n-alkyl dimethyl benzyl ammonium chloride, was
used the first day.
Location #4 was assigned to the roof of the hospital. The site was not
near any of the exhaust vents or air blowers. No smoking was observed
during the monitoring period.
Trip 3—
The third trip to the hospital took place in August 1985. All sampling
locations were identical to those selected for the first two trips. The
building was fully occupied and operational at the time of sampling.
Location #1, the visitors' lounge, contained a television which
remained on during most of the daytime hours. Patients, particularly
smokers, occupied the lounge each day. Windex was used each day on the
ashtrays and the vinyl chairs. No other cleaning products were observed.
Location #2, the nurses' station, was identical to that described
above. Hi-Torr, LpH, Simple Green by Sunshine, and Windex were the
cleaning products used daily. No smoking was observed in the area during
field monitoring.
Location #3 was an occupied patient's room. Cleaning products were
Identical to those used at the nurse's station. No smoking was observed.
No unusual activities were noted at the outside location on the roof.

Office (Old)
General Area Description—•
This building was an office building located at 301 4th Street, S.W. in
Washington, DC, in the middle of an urban office building section. There
was no open land in the immediate vicinity, with the exception of a rail-
road right-of-way located to the south of the building. Air flow in the
area was uneven due to the presence of large office buildings. Traffic
flows in the area were generally heavy, especially on 4th Street, a major
thoroughfare. Traffic flows were estimated to be 750 vehicles per hour at
peak. Side streets carried an estimated 300 to 500 vehicles per hour.
Building Description--
This building, constructed in 1983, was an eight-story, commercial,
office building located in a dense area of large, commercial structures.
The building used the municipal water supply, and the only supplementary
air systems were bathroom exhausts and special air conditioning in a small
computer facility. Temperatures in the building were maintained at 74*F in
the winter and 78*F in the summer, but the air handling systems were turned
completely off from 7:00 pm to 7:00 am. The humidity was not controlled.
No major interior maintenance or decor changes had been made. There had
been some interior painting, using water-based paints. There had also been
minor renovations of small areas and some movement of material. Daily
cleaning involved the use of an ammonia and water solution as needed to
supplement dusting and vacuuming. Pesticides were applied where needed on
a monthly basis with the last applications being two weeks prior to
monitoring.
Monitoring Location #1 - 3rd Floor
This location was approximately 250 square feet in area providing
access to four elevators. The alcove was separated from the other parts of
the building by swinging glass doors to the hallways. These doors were
kept open during the day and shut and locked at night. Ventilation was
provided to the elevator alcove through the doors from the building hall-
ways, with the outlet above the hanging ceiling. Air velocity past the
sampling station was very high during the day and nonexistent at night.
Human traffic was very heavy during the daytime. There were no furnishings

1n the area. The floor was covered with carpet. The carpet extended
completely up the walls. A hanging tile celling was present. The area was
vacuumed daily. No other sources of chemicals were observed or reported.
The amount of smoking which took place 1n this area 1s unknown.
Monitoring Location #2 - 5th Floor Hallway—
This area was a 150 square foot hallway on the fifth floor. There were
four doors leading to rooms located near the monitoring equipment. These
doors were generally kept open during the monitoring period. No other air
supply was present. A return to the common plenum was present. The only
item located in the area was a dry chemical fire extinguisher mounted on
the wall. Walls were covered with water-based paint. The floor was
carpeted and was vacuumed daily. No other sources of chemicals were
observed or reported. The amount, of smoking which took p]?ce in this area
is unknown.
Monitoring Location #3 - 8th Floor Hallway---
This area was a 360 square foot wide walkway outside a conference room
and near an elevator lobby. Air was supplied from other areas and returned
to the common plenum. The only furniture fri the area was a temporary room
divider placed in front of the monitoring equipment. It contained fabric
and foam in a metal frame. Walls were coveted with water-based paint, and
the floors were covered with two year old carpet, which was vacuumed daily.
No sources of chemicals were observed or reported. The amount of smoking
which took place 1n this area is unknown,
Monitoring Location #4 - Roof-
Monitors were located under an overhang on the east side of the roof.
They were at a major air intake enclosure exposed lo the ambient
conditions. No smoking was observed in this area.

Trip 1-
office building was a newly constructed
one-story building. The building was Immediately bounded on the east,
west, and south by one-story office buildings of like construction. The
building was bounded on the north by an approximately 200 car parking lot.
Within one-half mile to the east were two-, three-, and four-story office
-------
64
buildings. To the south were several two-story apartments and a building
materials and home Improvement store. Within one-eighth mile to the west
was an open, grassy area and a six-story office building. Across Waples
Mill Road to the northwest and Fender Drive to the north were two three-
story office buildings.
Within a one-half mile radius, there were no bodies of water or
streams, no dilapidated or demolished buildings, and no structures that
would obstruct the normal flow of air, and there were no point sources
observed 1n the area or reported by the builder. There were scattered
trees in the area. An estimated 50 percent of the land was open, with the
remainder in pavement and buildings.
Roads within the half-mile radius included Routes 236 to the south and
50 to the west, both of which are four-lane divided highways with very
heavy traffic. Approximately one mile to the east was US 66, a major
expressway that connects points west out of Washington. There were other
roads, like Waples Mill and Fender Roads, plus side streets that served the
office complexes in the area. Peak traffic times were presumed to be
morning and evening rush hours.
Building Description—The building had been under construction for
approximately one year. The approximate size of the building was 32,000
square feet. The source of water was public, coming from the Potomac
River. Electricity was the only fuel source in the building. The only
type of secondary sources of heating (central heat pumps are the main
source) were two 18' x 20' Fasco electric wall heaters mounted at two
entrances on the northeast side of the building. Secondary ventilation
sources Included Penn Zyphyr ventilation fans in bathroom ceilings and a
roof-vented exhaust system for a Jenn Air Grille. Temperature settings on
the cool/heating thermostats were set at 70*F. Summer thermostat settings
were unknown.
On the date of the building visit, the bathroom facilities and stain-
less steel water fountains had been cleaned with Ajax Cleaner, 3M Stainless
Steel Cleaner, Crown Ammonia, and Masury Concentrated Ammonia. The
Interior and exterior of the building had not been treated with any
pesticide. A blueprint of the entire building is shown in Figure 4.

room.
Carpeting and cove base molding were of the same type described for
monitoring location #1. There was no furniture in the room. The room was
vacuumed every weekday.
During the three-day monitoring period, there were no aerosol products
used at the location. Immediately prior to monitoring, a nearby bathroom
was cleaned with housekeeping products. No pet collars, pest strips, or
tobacco smoke were observed. No windows were opened. Monitoring began in
the evening. During that day, a nearby bathroom was cleaned and stripped.
Particle board was cut across the hall from the monitoring location during
the day. The next day, mastic was used to affix cove base molding in the
monitoring room during the daytime. Mineral spirits were used to remove
and clean the mastic. During the third monitoring day, cove base molding
was removed and replaced across the hall from the monitoring location.
Mineral spirits were used across the hall to clean and remove old mastic.
The cleaning products specified below were used to clean the bathroom
near this monitoring location. Each product was used once a day. Five
gallons of Masury-Columbia Super Stripper (concentrated ammonia) was used
to clean 800 square feet of the bathroom (on January 25 only). Two ounces
of Ajax Cleanser were used to clean 20 square feet of surface area. Two

69
ounces of 3M Stainless Steel Cleaner were used to clean 10 square feet of
surface area. Eight ounces of Crown Ammonia (dilute ammonia) were used to
clean 30 square feet of surface area.
Monitoring Location 14 - Outdoors—Monitoring location #4 was an
exterior location at the building entrance on the southwest side of the
building.
During the three-day monitoring period, no pet collars, pest strips, or
tobacco smoke were observed. During the first monitoring day, construction
work was underway in the adjacent building. Windows were washed nearby
during the day. No activities were observed during the second monitoring
day. A strong smell of wood smoke was noted at night. During the third
day, wood smoke was again noted at night.
Trip 2—
The second trip to the new office took place in April 1985. The
primary difference in the sampling site at this time was that the building
was fully occupied during the 72-hour monitoring period. All sampling
locations were identical to those selected for the first trip.
Location #1 (Office R-4) was a general office area occupied during the
day by three to four workers, including two smokers. Moderate smoking was
observed during the monitoring period. Use of cleaning, housekeeping, or
aerosol products was not observed during the monitoring period.
Location #2 (Office, R-l) was a general office occupied by five to six
workers, including one smoker. Light smoking was observed during the
monitoring period. Three typewriters and one computer were used during the
day. Use of cleaning or aerosol products was not observed.
Location #3 (Office, R-7) was an office occupied during the day by two
to three office workers. No smoking was observed during the monitoring
period. This office was immediately adjacent to a copier room, which
contained three mimeograph machines with ink. These machines were used
daily. The use of cleaning or aerosol products was not observed.
Location #4 was assigned to an area just outside of the side exit door.
Although construction on the building itself was complete, both land-
scaping and paving occurred during the sampling period. Asphalt patching
and paving of the parking lot adjacent to the west wing of Building "B"
took place throughout the 72-hour sampling period. The installation of the
-------
70
Irrigation system and planting of trees also occurred during the 72-hour
sampling period. No smoking was observed during the monitoring period.
Office/School (Old)
General Area Description—
The Belfer Center, JFK School of Government, Harvard University 1s a
combination lecture auditorium, conference center, faculty office building,
and computer facility. Food services were provided on the ground floor
level. The five-story building was bounded on the east by university dorms
and the Elliot House, on the northeast by a three-story parking garage
(under construction) and assorted residential/commercial buildings (shops
and restaurants on the lower floors and dwellings above), on the northwest
side by a court yard and new, ten-story hotel, and on the southwest side by
an open field, just beyond which were Memorial Drive and the Charles River.
The only body of water within one-half mile radius was the Charles
River, located approximately one-quarter mile from the Belfer Center. The
area within a one-half mile radius was a mixture of university buildings,
commercial shops and restaurants, and residential housing (usually on the
upper floors of buildings), with very few open areas or fields.
The buildings on the northwest, northeast, and east sides probably
constrict, though not severely, the flow of air 1n and around the Belfer
Center. The east side entrance to the Belfer Center was at street level,
while the northwest entrance was at ground level, or one level below
Kennedy and Elliot Streets. This might be of Interest because the air
Intake to the HVAC was located near the ground level entrance. Given the
below-street-level location of the intake and the presence of other
building obstructions, including the Belfer Center itself with its shape,
the air Intake area was not 1n an area of generally unrestricted airflow.
There were very few trees in the area, with most of them located along
both sides of the Charles River. An estimated 90% of the land area was in
buildings and pavement; the remainder consisted of a few open areas and the
Charles River Itself. The building manager was not aware of any point
sources for the chemicals being studied, but suggested that nearby Mount
Auburn Hospital might be considered one.
Roads within the half-mile radius Included Kennedy Drive 1n front of
and to the east of the Belfer Center, Elliot Street on the northeast side
-------
71
of the Center, and Memorial and Storrow Drives within one-eighth to a
quarter mile to the south. Memorial and Storrow Drives, in particular,
carry heavy volumes of traffic into and out of Boston and Cambridge at peak
hours (morning and evening rush hours). These two roads, plus Kennedy
Drive and Elliot Street, carry a constant stream of local daytime traffic
into and out of the nearby university community.
Building Description—
The uses of the building were those described above. Main construction
of the building was completed in 1984, and the building was occupied in
September, 1984. The estimated size of the building is 42,000 square feet.
The sources of water for Cambridge were Stoneybrook Reservoir, located at
Lincoln, Massachusetts, and Hamsbrook Reservoir, located at Weston-Waltham,
Massachusetts. A third source, Freshpond in Cambridge, was used as a
supplementary source, according to the City of Cambridge Water Department.
Electricity was the only power source in the building, including that for
kitchen use.
The secondary air conditioning units used in offices throughout the
building are Nibco-brand air conditioning units. These were water-fed
units capable of cooling, heating, and recirculating available room air.
Air is pulled into the unit at floor level through a filter located under-
neath the unit. The units are located on the outside walls of perimeter
offices throughout the building. These units conditioned and recirculated
available room air, not air from outside the building.
The only secondary ventilation devices known were bathroom and kitchen
exhausts, and no technical information about them was obtained. These were
roof exhaust devices. The usual building temperature control settings were
unknown to the building manager.
On the day of monitoring, equipment installation (February 25, 1985)
and painting of the lecture hall walls and hallways outside monitor
locations in rooms 125 and 224 was begun. Flat latex paint was used.
The interior of the building was treated with pesticides by Waltham
Chemical Company. The food service area was inspected and treated 24 times
a year. Other building areas were inspected and treated 12 times a .year.
The last treatment of all restrooms and the kitchen was on February 7,
1985, between 7:00 and 9:00 am. One gallon of Dursban Lo (Dow Chemical) at
-------
72
0.5% concentration was applied in a "spot" treatment fashion. This is an
emulsifiable insecticide. On January 10, 1985, one gallon of Safrotin
(Sandoz Pharmaceuticals) at 0.5% concentration was "spot" applied to all
restrooms. Previously used treatments (November and December, 1984)
included PCQ anticoagulant rodenticide baits, Talon G baits, and boric acid
used as an insecticide. No exterior treatments had been applied to date
(since construction and occupancy of the Belfer Center addition).
Figure 5 gives a diagram of the monitoring area with each location
marked.
Monitoring Location #1 - 1st Floor Renovated Office--
Monitoring location #1 was an interior location about fifteen feet
above Elliot Street on the northeast side of the building. It was a
rectangularly-shaped conference room (91 x 12') with an approximately nine
foot ceiling and 96 square feet of usable floor space. There was one door
entrance opposite a fixed window. There were no other penetrations of the
room.
Air supply and conditioning was provided by the building HVAC system
and by perimeter Nibco air conditioning units. The HVAC system was
supplied with steam and chilled water from a central campus plant. The air
handler serving the monitoring locations was designated as SAF-2. Filters
for the air handler were throw-away type of woven glass fiber.
There were no foam insulation, polyurethane, or asbestos products in
the room. The wall material was gypsum board with latex paint. Plastic in
the room consisted of 11 square feet of cove base molding (adhesive not
determined). Particle board items included the covering/window seat
construction over the perimeter fan coil. There was a round table with
nine square feet of surface area and a metal base. Construction of the top
was of particle board, plywood, and solid bentwood frame. Two chairs with
metal bases and molded plywood backs and seats were in the room.
The carpeting was about one year old. There were 72 square feet of
carpet (the floor area of the room was smaller than the general dimensions
of the room suggest because the covering/window seat construction over the
perimeter fan coil unit reduced usable floor space). The room had not been
treated with pesticides.

The room was not occupied. No smoking was observed throughout the
monitoring period.
Monitoring Location #3 - 3rd Floor, Occupied Office--
Monitoring location #3 was an interior location about 50 feet above
Elliot Street on the northeast side of the building. It was a
rectangularly-shaped (81 x 18') faculty office with approximately nine foot
ceiling and 120 square feet of usable floor space. There was one door
entrance opposite a fixed window that had an operable window section (11" x
60"). The operable window section was used infrequently as a fresh air
source. There were no other penetrations of the room.
-------
76
Air supply and conditioning was not provided by the building HVAC
system. Air conditioning and recirculatlon was provided by the perimeter
coil unit.
There were no foam Insulation or asbestos products 1n the room. Poly-
urethane 1n the room was 1n the form of seat cushions on three chairs. The
wall material was gypsum board covered with latex paint. Plastic in the
room consisted of 17 square feet of cove base molding (adhesive not
determined). Particle board Hems included the covering/window seat
construction over the perimeter fan coil.
Furniture included
a metal desk, one year old, with 12 square feet of surface area;

communications unit attached.
The carpeting was about one year old. There were 144 square feet of
carpet. The room had not been treated with pesticides. This office was
occupied by two persons. No smoking was observed throughout the monitoring
period.
Monitoring Location #4 - Outdoors--
Monitoring location #4 was at an exterior location at ground level on
the northwest side of the building. It was located approximately halfway
between the loading dock/dumpster area and the northwest entrance to the
building. It was also positioned only a few feet from the air intake to
the HVAC system. No smoking was observed during the monitoring period.

Nursing Home (New)
Trip 1—
General Area Description—The St. Francis Home for the Elderly located
in Worcester, Massachusetts, consisted of two structures - the original
building, constructed in the 1920s or 1930s, and the new addition, where
the indoor air .nonitoring was performed. Both the old and new structures
faced south. The new structure was immediately bounded on the south by the
old structure. The new structure was connected to the old structure by an
above-the-ground enclosed walkway. Both structures together occupied a
block of land that was bounded on four sides by streets.
The new structure was bounded on its west, north, and east sides by
two-story residential homes. However, approximately one-half mile to the
west, just beyond the residential homes, was an area of warehouses, light
manufacturing plants, and numerous auto paint and body shops. Within one-
half mile to the north was an open field about the size of a baseball
field. There were no bodies of water within a one-half mile radius.
The area was hilly, and the new structure, while not the highest point
was higher than most of the town. Because of its location on the side of a
hill, surrounding structures generally did not restrict the normal flow of
wind around the building. There were few trees within a one-half mile
radius. No condemned or demolished structures were observed in the
surrounding area. Because the new building was in the midst of a residen-
tial area, neighborhood streets networked the area.
The major traffic artery in the area, located about three-quarters of a
mile to the south-southwest, was Interstate 290,,
Building Description—As indicated, the building under study was a
residential home for the elderly (approximate size - 13,940 square feet).
Construction was begun in March 1984, with excavation actually begun in
December 1983. Completion of the building was expected in May 1984. The
new building was unoccupied at the time of the first monitoring visit.
There were three floors that were designed for residential living. The
first floor at the east end of the building was at ground level. The
terrain underneath the building slopes so that the west end of the building
was approximately 25 feet above ground level. The area underneath the
building was a covered parking area.
-------
78
Sources of water for the building were Kettlebrook Reservoir Numbers 1,
2, and 3, located at Paxton and Lester, Massachusetts. An additional
source was Coes Reservoir located to the southwest of Worcester.
The primary sources of heating for the building was hot water circu-
lated through baseboard units and forced warm air, both supplied from a
plant in the original building. Oil was the primary heating fuel and gas
was the secondary fuel. There was no air conditioning system. Secondary
exhausts Included bathroom exhausts. There was no kitchen 1n the new
building and thus no secondary exhausts as usually found in a kitchen.
The temperature settings were expected to remain at 75 degrees both day
and night. There was no humidity control.
While the building was under construction, no attempt was made to
routinely clean the interior. However, approximately three weeks prior to
the monitoring visit, the first floor was given a general cleaning. It was
dusted and the walls were wiped with a general purpose sanitizing cleaner
called ServiceMaster III. Its formulation included: octyl-decyl-dimethyl
ammonium chloride, 1.75%; dioctyl-dircethyl-C12, 40%; C16, 10%; dimethyl
benzyl ammonium chloride, 2.33%.
Figure 6 gives a diagram of the moitoring area with each location
marked.
Monitoring Location #1 - Day Room—Monitoring location #1 was an
interior location Intended for use as a day room. It was located on the
third floor, approximately 45 feet above street level, at the southwest
corner of the building. It was a 24' x 12' rectangle with a 9' ceiling.
There was one door entrance, which opened onto the main corridor. There
were no ceiling or floor penetrations. There were four windows, each 6
feet in length, that could be opened for ventilation. Since the building
was unoccupied, it was not known what percent of the time they would be
used for ventilation. They were closed at the time of the monitoring. All
weatherstripping on the windows was new.
There was no air conditioning system in the building. The forced warm
air heating outlets were located in the main corridor ceiling outside the
day room.
There were nine seats (chairs and love seat) in the room. The seat
backs and seat cushions were estimated at 96 square feet of surface area.
Each seat, back and cushion contained urethane foam mixed with a resin

treated polyester fiber. There were no asbestos or particle board items in
the room. Vinyl products 1n the room included 28 square feet of vinyl cove
base molding and 288 square feet of vinyl flooring. The vinyl corlon
flooring was the Brigantine (Forbo Smaragd) series by Armstrong. The 216
square feet of wall covering on the east wall of the day room was vinyl.
The adhesives and preparation materials used to affix the wall paper
and flooring included Sherwin Williams Promar latex wall primer containing
vinyl acrylic resin, pigments, silicates, and water. The flooring adhesive
was Armstrong Vinyl S89 Tile Adhesive containing petroleum naptha. Other
products included HB Fuller Cove Base Adhesive 714 (petroleum distillates)
and HB Fuller Floor Covering Adhesive 733 (petroleum distillates).
There was no carpeting in the room. No pesticides had been applied in
the building. There was no gas stove, gas or kerosene space heater, free-
standing fireplace, clothes dryer, humidifier, or filters or particle
scavengers in the room. No smoking was observed during the monitoring
period.
The room was not vacuumed or dusted regularly. The last time it was
dusted was approximately three weeks prior to installation of the air
monitoring equipment.
Monitoring Location #2 - Nurses' Station—Monitoring location #2 was an
interior location. It was intended as a nurses' station and was located in
the middle of the third floor corridor. It was a rectangular work area,
approximately 13' x 7', that opened on two sides onto the main corridor. A
counter top work surface encloses the nurses' station, except for a walk-
through opening that permitted access inside. The ceiling was 9 feet.
The other 13' side of the station was penetrated by a single door that
opened into a small workroom. The wall also contained four electrical
panels, with 34, 40, 24, and 18 circuit breakers. There was also a moni-
toring and control for the heating unit panel on the wall. The remaining
50 square feet of wall surface in the station was covered with vinyl wall
covering.
Other electrical equipment included a 96 button Dukane telephone center
made of metal and plastic, approximately 12" x 20" x 4".
There was approximately 10 square feet of cove base molding and 91
square feet of vinyl floor covering in the station area. Adhesives similar
to those used in the day room were used to affix the cove base molding.
-------
81
Wall cabinets and an L-shaped desk top area with eight drawers under-
neath were made of particle board and plywood. The drawers were 5" deep x
24" x 24". The new wall cabinets measured 9" deep x 30" high x 76" long.
The desk top area was 12' x 24" or approximately 24 square feet of veneered
surface area. Urethane finish was applied to the wall cabinet.
No smoking was observed during the monitoring period.
Monitoring Location #3 - Patients' Room—Monitoring location #3 is a
single occupant room. The room, Including bath, is a 24' x 12' rectangle.
The enclosed bath 1s 7' x 11', leaving an L-shaped bedroom of 211 square
feet of floor area. The room was approximately 25 feet above street level.
There was one window in the room on the south side wall of the building.
Weatherstripping around the window was original (new). One door penetra-
tion went into the bath and the other Into the main corridor. There were
no penetrations of the floor or ceiling.
Vinyl products included 25 square feet of cove base molding, 211 square
feet of vinyl flooring in the main room, and 77 square feet of vinyl
flooring in the bath.
Particle board items in the room Included a stand-alone wardrobe and
two small dressers. The stand-alone wardrobe was 2' wide x 2' deep x 6'
high. It was made of veneer-covered particle board. The two small
dressers had veneer-covered particle board tops. One dresser top was 18" x
30" and the other was 24" x 17".
Other pieces of furniture in the room included a metal frame bed with
head and foot boards made of veneered particle board, one metal trash can,
one wood frame chair with a vinyl-covered seat back and cushion, and a 27"
x 37" cork bulletin board. Electrical equipment in the room included a
fluorescent lighting fixture on the wall above the head board.
The 137 square foot west wall of the room was covered with a vinyl wall
covering. There was no carpeting in the room.
No smoking was observed during the monitoring period.
Monitoring Location #4 - Outdoors—Monitoring location #4 was an
exterior site. It was located on a third floor balcony at the east end of
the building. The balcony was sheltered on three sides and above and was
open on the fourth side. It was located approximately 25 feet above the
ground. No smoking was observed during the monitoring period.
-------
82
Trip 2—
The second trip to the new nursing home took place 1n August 1985. The
primary difference 1n the sampling site at that time was that the home was
occupied with staff and patients and was fully operational. Monitoring
locations were Identical to those used during the first trip except for
monitoring location 13.
Location #1 was assigned to the west day room. The use of aerosol
products and smoking were not observed, Johnson Multi Furniture Polish and
ServiceMaster Sanimaster III floor cleaner were used daily. RTU Wallglide
vinyl cleaner, ServiceMaster RTU Glassclene, ServiceMaster Odor-Go and
ServiceMaster Scrub and Shine were used occasionally.
Location #2 was assigned to the nurses' station. No smoking was
observed in this area. The cleaning products listed above were also used
at this location.
Location #3 was an unoccupied two-patient room located directly across
the hallway from the room previously sampled during Trip 1. No smoking was
observed in this area. The cleaning products listed above were also used
at this location.
Location #4 was assigned to an outside area directly below the last air
intake for the third floor. This area was located on a balcony at the east
end of a central hallway. A sliding glass door opened onto the balcony.
In this location the air samples could contain chemicals exiting from this
building. No smoking was observed during the monitoring period.
Since the building did not have central air conditioning, windows and
doors were left open during the 72-hour sampling period.

SECTION 6
SAMPLE ANALYSIS
All samples collected during field monitoring (Section 4) were analyzed
using the protocols described in the Draft Work Plan, Part II: Analytical
Protocols (17). In this section, details of sample analysis are given for
each parameter including analytical method, quality control results, limits
of detection, and quantisation method.
VOLATILE ORGANICS
Analytical Method
Gas chromatographic/mass spectrometry (GC/MS) analysis of volatile
organic compounds was performed using a combined liquid injection/thermal
desorption unit designed and fabricated at RTI. This unit was designed to
allow calibration of the mass spectrometer by splitless/split liquid injec-
tion with analysis of field samples collected on Tenax GC cartridges by
thermal desorption.
In the thermal desorption mode, recovery of volatile organics was
accomplished by heating the Tenax cartridge to 270*C and purging with
helium into a liquid nitrogen cooled, nickel capillary trap (18,19,20,27).
The vapors were then introduced into a high resolution fused silica chroma-
tographic column for component separation (19,20)., Identification and
quantification of the constituents in the sample were performed using
electron impact mass spectrometry by measuring the intensity of the
extracted ion current profile (19,21,28). GC/MS conditions used during
sample analysis are given in Table 16.
Thirty-four target volatile organic chemicals were quantitated in each
sample. Immediately prior to GC/MS analysis, each Tenax cartridge was
loaded with bromopentafluorobenzene (212 ng) to serve as an external quan-
titation standard. Quantitation of GC/MS results for the target volatiles
was accomplished using response factors (RF). RF values for each target

chemical were generated by analyzing five 1 /iL Injections of a calibration
solution (Table 17) over a 3-day period. For each Injection, response
factors relative to the external standard, bromopentafluorobenzene, were
calculated as:
RFT = AT * n%
AES • ngT
where
ngj = the ng of target volatile injected;
Ay = the peak area of the target compound;
nQES = tne n9 °f external standard Injected;
A£S = the peak area of the external standard; and
RFy = the response factor for the target compound.
Average response factors and standard deviations were calculated for each
target volatile.
During each day of sample analysis, two additional liquid injections of
the calibration standard were analyzed. If the RF values calculated for
these injections fell within +2 S.D. of the average response factor, then
the GC/MS system was considered in control and the average RF values were
then used to quantitate targets on sample cartridges as:
ngT
RF
Quality Control Results
Sets of quality control samples were prepared for each sampling trip.
Each set contained an unspiked cartridge to serve as a blank and a spiked
cartridge (~50-100 ng/compound) , which served as a control. All field
controls and blanks were analyzed. Laboratory QC samples were processed
only if poor results were obtained from the field QC samples. Percent
recovery was calculated as:
% Recovery = ngC - ngB X 100%
ngspiked
where ngc is the average amount of target compound found on spiked
controls; ngg is the average amount of target compound found on blank

concentrated standards (Solutions I, II, and III), the four most concen-
trated standards (Solutions I, II, III, and IV), the five most concentrated
standards (Solutions I, II, III, IV, and V), and finally all six standards.
These calculations are summarized 1n Table 22.
Generally, as the RFs from the less concentrated standards are added
for calculation, the % RSDs of the calculated response factors Increased.
When the Inclusion of a response factor from one of the low concentration
standards caused the % RSD of a target volatile to exceed 20%, then the
Injected mass from that standard was defined as the quantifiable limit.
For example, for epichlorohydrln, the % RSD of the mean response factors
becomes greater than 20% when the response factors from Solution IV (52 ng
injected) are included 1n the data base, and therefore, the quantifiable
limit is 52 ng. For the n-alkanes the % RSD becomes greater than 20% when
RFs from Solution V (15 ng Injected) are Included in the calculations so
the quantifiable limits would be defined as 15 ng. For the compounds that
exhibit acceptable % RSDs throughout the concentration range studied, the
quantifiable limit was arbitrarily set at 50% of the mass injected using
Solution VI, the lowest concentration standard. Because of poor
chromatographic behavior during liquid injections, the LOD for
1,2-dichloroethane was calculated using a different approach. Here the LOD
was defined as the lowest standard concentration where a greater than 25%
decrease in RF was observed compared to the other standard. The limit of
detection was defined as one-fourth the QL. The QL values in Table 23 are
reported as both ng/cartridge and ng/L in air assuming sample volumes of
10, 15, and 20 liters.
Sample Analysis
Throughout this project, all samples collected for volatile organics
were collected, analyzed, and processed in triplicate using distributed air
volumes during sample collection. As described previously, output from the
GC/MS analysis was ng of target per cartridge. This mass (ngj) was then
corrected for background by subtracting mean values for each target found
on field blanks (ngfj) from the same trip. No correction was made for
recoveries calculated from field controls. Concentrations were then calcu-
lated using the total sample volume (V) as:

These calculations were performed using a computer program. The
program also calculated the mean and percent relative standard deviation
(%RSD) for all colocated samples. If the %RSD was greater than 30 percent,
then the Identity and peak area of target compounds were verified from the
original data files. Generally, %RSDs were less than 20%. Poor precision
(RSD = 20%) was found under certain conditions.
1. If targets were found at variable levels on field blanks, as for
benzene and styrene;
2. If the targets were present at levels below the limits of
detection; and
3. If the targets were polar compounds, such as the cresols or n-butyl
acetate.
NITROSAMINES
Analytical Method
Cartridges collected for nltrosamine analysis were sent to Thermedics
(Waltham, MA) for analysis. A solvent backflushing technique was used to
elute the samples, which were then analyzed using a gas chromatograph
interfaced with a TEA™ detector and confirmed by HPLC TEA analysis
(22,28).
Analysis was performed for n-dimethylnitrosamine, n-diethylnitrosamine,
n-dipropylnltrosamine, n_-d1 butylnitrosamine, n-nitrosopiperdine, n-nitroso-
pyrrolldine, n-nitrosomorpholine.
QC Results
Sets of quality control samples were prepared for each sampling trip.
Each set contained an unspiked cartridge to serve as a blank and a
cartridge spiked with n-nitrosomorpholine and/or n-dimethylnitrosamine or
n-dipropylnitrosamine to serve as a control. Field control and blanks were
analyzed with field samples. Percent recovery for spiked controls was
calculated as:
% Recovery = ngFC " ngFB X 100%
n9sp1ked
where ngpc is the average amount of target compound found on field
controls; ngpjj 1s the average amount of target compound found on field
blanks, and ngsp^ec| 1s the amount of target compound spiked onto field
controls. Results of QC analysis are given 1n Table 24,

Data shows acceptable recoveries for field controls with no contamina-

Limits of Detection
Limits of detection were reported by Thermedics as shown In Table 25.
The quantifiable limit was considered the same as the LOD.
Sample Analysis
The analysis strategy for nltrosamlnes Involved a sample screen prior
to analyzing all samples. That 1s, one sample for each trip from each
location was analyzed first. For each location, samples with the highest
probability of containing nltrosamlnes (I.e., time periods where smoking
had occurred) were selected. If either d1methyln1trosam1ne or n-nitros-
morphollne were detected, then all samples from that trip were analyzed.
If neither nltrosamlne was detected, then no further samples from that trip
were analyzed.
Output from GC/TEA analysis was ng of nitrosamine per cartridge. This
mass (ngn) was then corrected for background by subtracting mean values for
each target (ngg) found on field blanks from the same trip. No correction
was made for recoveries calculated from field controls. Concentrations
were then calculated using the total sample volume (V) as:
ng/L = ngn
rrn
MISCELLANEOUS VOLATILES
Analytical Methods
Ethyl ene oxide and other trace organics including acrylonitrile, vinyl
chloride, vinyl idene chloride, chloroform, acrolein, n-propanol, n-butanol ,
propanone, 2-butanone, and phenol were collected on 150 mg charcoal tubes
(SKC Lot 107 charcoal) using approved NIOSH methods. In the proposed
analytical method, each charcoal tube 1s broken and the front and back
sections of the charcoal transferred to a glass vial and solvent desorbed
using 0.5 mL carbon disulffde (€$2). A mixture of C$2 and 2 percent
acetone was proposed for desorblng acrylonitrile. After desorption,
extracts are analyzed by gas chromatography with a flame ionlzation
detection. A nitrogen phosphorous (NPD) or an electron capture detector
(ECD) was proposed for more sensitive detection of nitrogen and halogen
containing targets.

Method validation experiments, along with analysis of control samples,
demonstrated significant problems in applying these methods to the analysis
of low levels of organic compounds 1n air. The most serious problems
included
1. low recovery «30%) of miscellaneous volatiles when spiked at
levels less than 200 /jg/cartridge,
2. problems with solvent interferences during chromatographic analysis
of low levels «25 ng//*L) of acetone, acrolein, ethylene oxide and
vipylidene chloride, and
3. poor collection efficiency of ethylene oxide using 150 mg charcoal
tubes.
Because of these problems and after consultation with the EPA Project
Officer, analyses of miscellaneous volatiles was not performed on any field
samples.
PESTICIDES/PCBs
Analytical Method
Recovery of target pesticides/PCBs from polyurethane foam (PUF) was
accomplished by a 14 h Soxhlet extraction of the PUF with 150 mL of 5%
ethyl ether in hexane. The hexane was concentrated to 1 mL by Kuderna-
Danish evaporation followed by nitrogen blowdown.
Prior to GC analysis, three external standards (dichloronaphthalene,
~20 ng; tetrachloronaphthalene, ~200 ng; and octachloronaphthalene, ~80 ng)
were added to each sample. All samples were analyzed by GC/ECD using the
conditions described in Table 26. Chromatograms of standard solutions of
the target pesticides/PCBs are given in Figures 7 and 8. Each pesticide in
the PUF extracts was quantitated using a response factor (RF) generated
relative to the external standard, dichloronaphthalene. Twelve peaks were
used to quantitate tech.-chlordane. RF values were generated by analyzing
standard solutions (Table 27) prepared in hexane containing known concen-
trations of each target and the external standard. For the target
pesticide, the RF was calculated as:
RF • P9P * AES

where Ap and AES are the peak areas measured for the pesticide and external
standard, respectively and pgp and pg^s are the pg of the pesticide and
external standard injected onto the GC column. For tech.-chlordane, it was
assumed that each peak in the GC pattern resulted from an equal amount of
tech.-chlordane. Since there were 12 peaks for quantitation, the relative
response factor for any individual peak (RF^) was calculated as:
RF. = P9TC/ 12 * AES
Ai ' P9ES
where A^ is the area of response of peak 1 and pgjc is the pg of technical
chlordane injected into the GC column.
Individual PCB isomers were quantitated using RFs generated at RTI on a
previous contract (29). Individual PCB isomers were identified by reten-
tion times relative to the external standards and by pattern comparison to
chromatograms of a standard solution containing a mixture of Aroclors 1016,
1254, and 1260.
Prior to analysis of PUF extracts, RF factors were calculated from five
injections of standard and average RF determined as given in Table 28.
Each day samples were analyzed, the calibration standards were analyzed and
the ratio of the RF from the daily injection vs. the average RF were
calculated. Response factors were considered in control if the ratio was
between 0.75 and 1.25. The average response factor was then used to quan-
titate pesticides injected for analyses using the equation:
pgp = RF • Ap« pgE$
AES
where Ap and A£$ are the peak areas measured for the pesticide and external
standard, respectively, and pgp and pg£$ are the pg of the pesticide and
external standard injected onto the GC column. If the RF was not in
control, the daily RF was used for quantitation.
Detector linearity was demonstrated for all compounds by analyzing
single injections of the six solutions given in Table 29. Estimated linear
range for each pesticide/PCB is given in Table 30. The upper range was
estimated based on response factor data generated during the analysis of
calibration standards.

QC Results
Quality control samples were prepared and analyzed along with field
samples for each monitoring trip. A method control was also processed with
each set of samples. Method controls were spiked immediately prior to
extraction at the same levels as the field control. Percent recovery for
control samples was calculated as:
% Recovery = ngc x 100%
ng spiked
where ngc is the average amount of target pesticide found on control
samples and ng spiked is the amount of target spiked onto that sample.
Results of the analysis of QC samples are given in Tables 31 and 32.
Dichlorvos was not detected on field controls, but gave good recoveries
(>70%) for method controls, suggesting that degradation probably occurred
during storage. Recoveries for Malathion were generally low ~40-50%. All
other compounds gave acceptable recoveries.
Field blanks were generally clean with little background contamination.
Limits of Detection/Quantitation
Estimated instrumental quantisation limits (QL) were calculated from
the data base generated for relative response factor determinations and
were defined as the number of pg injected onto the GC column and which
would give 100,000 area counts during analysis. The calculation for QL is:
QL _ pgp x 100,000
AP
where pgp is the amount of pesticide injected and Ap is the GC/ECD area
response resulting from analysis of standard solutions at 100 mV
sensitivity. For tech.-chlordane the QL was calculated as the amount of
tech.-chlordane injected and which would give an average area response of
100,000 counts for each peak. For PCBs, the QL was estimated as the amount
of tripart solution injected on column and which gave an area response of
25,000 counts for 33% of the PCB isomers.

All of these QLs were above the lower limit of linear range except for
Ronnel. In this case the QL was defined by the linear range. The instru-
mental detection limit was defined as one-fourth the QL. Instrument
detection parameter are listed in Table 33.
Sample Analysis
For all trips, a sample screening was performed. This screening
consisted of processing one sample from each location for each trip. If
pesticides were not detected at elevated levels during screening, then no
further samples were analyzed.
As described previously, output from GC/ECD analysis was pg of target
injected. This was converted to pg per sample as:
DO = P9T x Ve
pgsample ' y x — -
where:
pgj = pg of target injected,
Ve = total volume of the extract in ftl, usually 1000,
Vi = volume of extract injected in /jl_, usually 1.
This mass was then corrected for background by subtracting mean values
for each target as determined from field blanks (pgg) from the same trip.
No correction was made for recoveries calculated from field controls.
Concentrations were then calculated using the total sample volume (V) as:
pg/m3 = P9r pg B
V (m3)
INHALABLE AND RESPIRABLE PARTICULATES
Analytical Method
Filters used for sampling inhalable (coarse) and respirable (fine)
particulates were weighed before and after exposure using a Mettler Balance
(Serial Number 650272) with certified accuracy to 0.001 mg. Filters were
equilibrated at 70 * *C and 50*2% relative humidity before weighing. All
filters were exposed to an ionizing source immediately prior to weighing to
reduce static charge and improve reproducibility of filter weights.
Results of filters weights were reported to the nearest /*g.

QC Results
Unexposed filters were set aside to serve as field and laboratory
blanks for each sampling trip. Blanks were weighed before and after
sampling at the same time as field samples. No control samples were
available. Data for blank samples are given in Table 34.
Limits of Detection
The method detection and quantitation limit were calculated as
Method LOD = % * 1 S.D.
Method QL = % * 2 S.D.
where X is the average mass found on the filter blank. Method detection
parameters are listed in Table 35.
Sample Analysis
Particulate concentration (P) 1n all samples was calculated as
FW - FU - FB
volume of air sampled (m3)
where
FV/BE is the filter weight before exposure,
FW/\E is the filter weight after exposure,
FB is the average amount of parti cul ate found on blank filters.
POLYNUCLEAR AROMATIC HYDROCARBONS (PNAs)
Analytical Method
After the respirable and inhalable particulate filters were weighed,
the two filters from each sample were placed together into a 20 ml scintil-
lation vial. Samples were extracted by adding approximately 20 ml of
methylene chloride to the scintillation vials and sonicating for thirty
minutes. All operations were performed under yellow light to prevent
photodegradation of PNAs.
To perform screening analysis, sample extracts were transferred to
screw-cap centrifuge tubes and the volume reduced to approximately 0.1 mL
by nitrogen blowdown. Each concentrated extract was quantitatively trans-
ferred to a Sep-Pak™ silica cartridge. The methylene chloride on the
cartridge was evaporated with N2- The Sep-Pak was then eluted with 10 ml
of hexane. The eluant was concentrated to 0.5 ml. These extracts were

Limits of Detection
For the metals that were detected on the field blanks, the method
detection limit and quantltatlon limit were calculated as:
Method LOD = 1 S.D.
Method QL = 2 S.D.
where S.D. 1s the standard deviation of the average amount of the metal
levels found on the filter blank. For metals that were not detected on
field blanks, the method detection parameters are equal to the Instrumental
detection parameters. Here, the Instrumental LOD 1s equal to the amount on
the filter that can be measured with a precision of *50%. Instrumental QL
was defined as the amount on the filter that can be measured with a
precision of *25%. Precision data was provided by Florida State
University. Method detection parameters are listed in Table 38 for the
nine target metals.
Sample Analysis
For all trips, a sample screening was performed as described for the
nitrosamines. If metals were detected during screening, then all samples
from that trip were analyzed.
Results of PIXE gave ng/filter for each metal. This mass was then
corrected for background by subtracting mean values for each metal found on
field blanks from the same batch. Concentrations were then calculated
using the sample volume as:
Concentration (ng/m3) = (ng/filter sample - ng/blank) x volume (m3)
FORMALDEHYDE
Analytical Method
Formaldehyde was recovered from molecular sieve samples by adding one
mL of deionized water to a vial containing the sieve and then equilibrating
for five minutes. The sieve was then poured into a 1.0 cm glass chromato-
graphy column. Deionized water was added to each column to completely
saturate the sieve. After ten minutes, 25 mL of deionized water was eluted
through the column at a rate of approximately 3 mL/min. The 25 mL eluate
was filtered through Whatman No. 2 filter paper and collected in a Teflon--
lined screw cap vial. The solution was reacted with 2.5 mL of acidified

pararosanlUne reagent (0.16 g pararosanlHne + 20 ml HC1 diluted to 100 ml
with delonlzed water) with mixing for -5 minutes. A 250 pi aliquot of
sodium sulfate (0.1% 1n water) was added and the color allowed to develop
at 25°C for 75 minutes.
The solution was Immediately transferred to a cuvette and the absorb-
ance or optical density measured at 570 nm using a Beckman, DU-2 spectro-
photometer. Samples were read against delonlzed water.
Because desorption efficiency and background contamination from the
sieve appeared to vary from batch to batch, quantitation of field samples
was performed using a calibration curve generated from field blanks and
field controls spiked 1n duplicate at four different concentrations ranging
from 3.25 to 18.5 /«g. Amount of formaldehyde on each sieve sample was then
calculated from the calibration curve as
where O.D. is the optical density for a given sample. Table 39
characterizes the calibration curves used for sample analysis.
Limits of Detection
Method detection limits (LOD) 1n /jg/sieve were calculated from the
results of field blank measurements as
LOD = x + 1 S.D.
where j( 1s the average amount of formaldehyde found on field blanks and
S.D. 1s the calculated standard deviation of the measurement. Method
quantitation limits (QL) were calculated as
QL = X + 2 S.D.
Amount of formaldehyde found on field blanks plus LODs and QLs for each
field trip are given 1n Table 40.
Sample Analysis
All collected samples were analyzed. Results of the parosaniline
analysis gave /*g of formaldehyde per sieve (/ig/s) corrected for recovery
from field controls and background on field blanks.
Since the volume of air taken for each sample was known, formaldehyde
concentration 1n ppb in air was calculated as

Problems
The procedure used for the collection and analysis of formaldehyde in
air samples was adopted from a procedure used successfully at RTI on a
previous contract (30). The original procedure used granular molecular
sieve to sample 30-70 L of air over a 15 to 30 minute period. The modified
method used powdered molecular sieve to allow sampling at lower flow rates
over the 24 hour period required by this contract.
The use of the powered molecular sieve produced several problems not
encountered previously:
a. Formaldehyde recovery from the sieve was variable,
b. background contamination of the sieve was often high and variable,
and
c. fines from the sieve produced during rinsing interfered with
analysis.
This method was used because other methods applicable to a 24 hour
sampling period were not available at the time field monitoring was
Initiated. Because of the problem encountered during analysis, results
should be viewed with caution.
RADON
Analytical Method
The exposed Track-EtchR monitors were analyzed by the Terradex
Corporation using a microscopic technique. Alpha-particles bombard the
plastic and cause radiation damage tracks, which are subsequently detected
by caustic etching and counting at 500X under a microscope. The number of
tracks counted per unit area is proportional to the average exposure rate
and the exposure time. Results are reported in (pCi/L)-month with a
detection limit of 1 (pd'/L)-month.
-------
126
QC Results
Five unexposed Track-Etch monitors were analyzed by the Terradex
Corporation to serve as quality control samples. Four of these samples had
been transported to the field with the sample. These have been designated
as field blanks. A single monitor was stored In the laboratory and
designated as a lab blank. Results of these analyses are given 1n Table
41.
AIR EXCHANGE
Analytical Method
Air samples that had been collected and stored in plastic syringes were
analyzed by GC/ECD to quantitate sulfur hexafluoride (SF§) concentrations.
Conditions for GC analysis are given in Table 42.
Whenever samples were analyzed, a calibration curve was first generated
to confirm instrumental linearity using SFs concentrations ranging from 200
ppt to 100 ppb. Each day of analysis, a standard prepared at 100 ppb was
analyzed to demonstrate instrument stability. If the instrument response
for SF$ had changed by greater than 15%, a new calibration curve to verify
linearity was generated. SFs in samples was quantitated using manually
measured peak heights. All of the samples collected from one site during a
single sampling period (one SFs release) were analyzed as a group to
minimize errors due to changes in instrumental response. This method was
previously validated and used at RTI (4).
Limits of Detection
The limit of detection for SFs in air samples was ~200 ppt.
QC Results
No QC samples were prepared or analyzed during exchange rate
determination.
Sample Analyses
All samples collected for each field monitoring trip were analyzed.
The GC/ECD analysis of air samples gave chromatographic peak heights for
air sampled at a specific time after SFe release Into the building. Air
exchange rates (ACH) at each sampling location are calculated as:

ASBESTOS
Analytical Method
Analysis of asbestos collected on filter cassettes was performed by
Energy Technology Consultants (ETC) using transmission electron microscopy
(TEM) at 20,000 X magnification. The procedure described in "Electron
Microscope Measurement of Airborne Asbestos Concentration - A Provisional
Methodology Manual" (EPA-600/2-77-178) was used for all analyses. Results
were reported as fibers/filter.
QC Results
Five unexposed filter cassettes were analyzed by ETC to serve as
quality control samples. All of these cassettes had been transported to
the field with actual field samples. Results of QC analyses are given in
Table 43.
Limit of Detection
The analytical detection limit as reported by ETC was 0.6 x 103
fibers/filter.
Sample Analysis
Sample screening was performed for each field monitoring trip. TEM
analysis gave fibers per filter (Ap). This count was then corrected for

SECTION 7
RESULTS
VOLATILE ORGANICS
Several types of statistical analyses were performed on the data for
volatile organics collected during field monitoring. Initially, the
percentage of air samples that had concentrations reported above the quan-
tifiable limits for each of the target volatiles was calculated. This
statistic is referred to as percent detected and was calculated for indoor
and outdoor air samples collected during each field monitoring trip. No
further analysis was performed on the seven organics that had low percent
detected values (less than 10% at either indoor or outdoor monitoring
locations). For the remaining compounds, the data were tabulated for all
monitoring locations with means and standard deviations calculated.
Summary statistics including mean, median, and maximum concentrations were
estimated for indoor and outdoor sample locations from each trip. Daytime
and nighttime means were also estimated for indoor samples. Indoor/outdoor
and day/night concentration ratios were then calculated. Differences
between indoor and outdoor concentrations, daytime and nighttime concentra-
tions and concentrations at different indoor locations were evaluated
statistically. Comparisons of mean concentrations were made between
buildings and sampling trips.
Prior to statistical analysis, several manipulations were performed.
First, because m-, o-, and p_-cresols gave poor and variable recoveries from
calibration standards and control samples, they were excluded from the
database. Second, because of the difficulty of maintaining sufficient GC
resolution between m- and p_-xylene, the quantitative values for these
compounds were added to give one total value for m-,p_-xy1ene. Third, the
mean and percent relative standard deviation for each volatile organic were
calculated for all of the triplicate colocated samples. A printout of
-------
133
these data for each sample is Included 1n Appendix D. The mean concentra-
tion values were then used for all calculations. Where the %RSD for
colocated samples was greater than 30%, 1t has been noted. Fourth, concen-
tration values below the quantifiable limit (QL) were used as reported.
Finally, because the triplicate colocated samples were collected using
different sample volumes, quantifiable limits were calculated for the
smallest sample volume.
Percent Detected
Table 44 lists percent detected values calculated for indoor and
outdoor monitoring locations at each sampling site for all 30 target
volatiles. After inspecting these data, each volatile organic was placed
into one of four categories (Table 45) depending upon frequency of
occurrence. Table 45 demonstrates that most of the "ubiquitous" volatile
organics were aromatic hydrocarbons such as benzene, the xylenes, ethyl -
benzene and some of the trimethylbenzenes. The only other volatile cate-
gorized as ubiquitous was 1,1,1-trichloroethane. "Frequently-occurring"
target compounds detected more often indoors than outdoors included the
remainder of the aromatic hydrocarbons, all of the target aliphatic
compounds, the two oxygenated compounds, and several chlorinated organics.
Three compounds, tetrachloroethylene, o-ethyltoluene, and 1,2-dichloro-
ethane, were frequently detected, but showed no trend in indoor versus
outdoor samples. The only chemicals that fell into the category "rarely
detected" were halogenated organics. The seven chemicals in this latter
category, including o-epichlorohydrin, chlorobenzene, carbon tetrachloride,
bromodichloromethane, 1,1,2,2-tetrachloroethane, o-dichlorobenzene, and
m-dichlorobenzene, were dropped from all further analyses.
Concentration Data
New Hospital--
Trip 1. Concentration data for volatile organics measured during the
first trip to the new hospital (July 1984) are given in Tables 46 to 49.
Concentrations are reported for each location by time period. Concentra-
tions averages and standard deviations for the entire 3-day period are also
given. It is interesting to note that the high levels of 1,2-dichloro-
ethane measured during the first night decrease to nondetectable levels by

the second night at all three Indoor and the outdoor sampling locations.
The source of this contamination 1s unknown, although 1t appears to be a
result of an outdoor pollutant.
The average concentration values from each of the preceding four tables
are summarized In Table 50. Comparisons of average concentrations at each
Indoor location Indicate a generally uniform distribution of volatile
organlcs throughout the monitoring area with few significant differences
between monitoring locations. Overall significant differences in reported
concentrations between the three Indoor locations was determined by an
F-test 1n analysis of variance. If the associated £-value was significant
at the 0.05 level, then paired comparisons between sampling locations were
analyzed using Bonferroni's correction (a - 0.05/3 = 0.017) to ensure an
overall a of 0.05. As indicated in Table 50, only isopropylbenzene, ethyl-
toluene, and trlchloroethylene showed differences in indoor concentrations
between the three monitoring sites. For all three compounds, highest
concentrations were in the patients' room; lowest concentrations in the
visitors' lounge.
Table 51 gives summary statistics calculated for this first trip to the
new hospital. Mean, median, and maximum concentrations were determined.
These statistics are given for Indoor and outdoor samples separately.
Indoor/outdoor ratios for the mean, median, and maximum concentrations have
also been calculated. Results generally show only small differences
between mean and median concentrations indicating that the data are not
skewed toward either high or low concentration values. m,£-Xylene (6.88
ng/L), 1,1,1-trichloroethane (4.98 ng/L), and n-decane (3.65 ng/L) showed
highest mean indoor concentrations. 1,2-Dichloroethane (2.58 ng/L) gave
highest mean outdoor concentration. A two sample t-test performed using
the mean concentration values showed significant differences (0.05 level)
between indoor and outdoor concentrations for benzene, m,p_-xylene,
o-xylene, styrene, ethylbenzene, Isopropylbenzene, m-ethyltoluene,
1,2,3-trimethylbenzene, 1,2,4-tr1methylbenzene, 1,3,5-trimethylbenzene,
2-ethoxyethyl acetate, 1,1,1-trichloroethane, and trichloroethylene. Only
benzene had higher measured concentrations outdoors. m,p_-Xylene (5.83) and
o-xylene (8.03) showed the highest Indoor/outdoor concentration ratios.

Table 52 gives mean daytime and nighttime concentrations calculated for
the Indoor locations only. Day/night concentration ratios have been calcu-
lated and are Included 1n the table. A two sample t-test performed using
the mean concentration values showed significant differences (0.05 level)
between daytime and nighttime concentrations for Isopropylbenzene, m- and
o-ethyltoluene, 1,2,3-trlmethylbenzene, n-decane, tetrachloroethylene, and
£-d1chlorobenzene. In each of these cases, daytime concentrations were
higher. For n-decane, Indoor concentrations were twice as high during the
daytime monitoring periods.
Trip 2. Concentration data for Trip 2 to the new hospital (October
1984) similar to that reported for Trip 1 are given 1n Tables 53 to 59.
Tables 53 to 56 give measured concentrations of volatile organlcs for
each location by time period. Mean concentrations and standard deviations
are also Included. The day before sampling started, the stairwell adjacent
to the visitors' lounge had been painted. A paint odor was still present
in the stairwell during monitoring. This activity could be responsible for
the elevated levels of n-decane, n-undecane, m-xylene, m-ethyltoluene, and
Ie2,4~tnmethylbenzene measured during the first evening at all indoor
sampling sites. In contrast, Indoor concentrations of 1,1,1-trichloro-
ethane tended to maximize during day 1. A suspected source for this
contaminant could not be identified. As with Trip 1, high levels of
1,2-dichloroethane were detected at all indoor and outdoor sampling
locations during Isolated time periods. During this trip, potential
sources for the pollutant were Investigated, but could not be found.
Average concentration values and standard deviations calculated for
each monitoring location are summarized In Table 57. A two sample F-test
comparing average concentrations at each Indoor location showed a uniform
distribution with no significant differences between monitoring locations.
Table 58 gives summary statistics for this second trip to the hospital.
Results generally show small differences between mean and median Indoor
concentrations indicating that the data are generally not skewed toward
either high or low concentration values. 1,1,1-Trichloroethane (4.50
ng/L), m,p_-xylene (3.13 ng/L), n-decane (2.73 ng/L) had highest mean indoor
concentrations. 1,1,1-Trichloroethane (3.18 ng/L) had highest mean outdoor
concentrations. These observations were the same as for the first moni-
toring trip. Mean concentration values showed significant differences at

the 0.05 level between Indoor and outdoor concentrations for the xylenes,
m-ethyltoluene, 1,2,3-tr1methyl benzene, 1,2,4-trimethylbenzene, n-decane,
and n-undecane. For each chemical, concentrations were higher Indoors.
m,£-Xylene (3.04) and 1,2,4-trlmethylbenzene (3.06) showed the highest mean
Indoor/outdoor concentration ratios.
Table 59 gives mean daytime and nighttime concentrations calculated for
the Indoor locations. A significant difference at the 0.05 level was found
between daytime and nighttime samples only for 1,2,3-trlmethylbenzene.
Mean concentrations were higher for nighttime samples. This Is a result of
the high nighttime concentrations found on the first day, presumably coming
from painting activities noted the previous day.
Trip 3. Concentration data for Trip 3 (August 1985) to the new hospital
are reported 1n Tables 60 to 66.
Measured concentrations for each location by time period are listed in
Tables 60 to 63. The hospital was fully occupied and operational at the
time of sampling. No unusual sources of volatile organics (I.e., painting)
were observed during this visit. Again, high levels of 1,2-dichloroethane
were detected at all Indoor and outdoor sampling locations during Isolated
time periods. And again, no potential sources for the chemical were found.
Average concentration values plus standard deviations for each
monitoring location are given in Table 64. As with trip 2, comparisons of
average concentrations at each indoor location show a uniform distribution
of volatile organics with no significant difference at the 0.05 level
between monitoring locations. Average concentrations of several organics
such as 1,1,1-trichloroethane, benzene, and n-decane appear to be higher in
the visitors' lounge. This 1s a monitoring artifact primarily due to high
levels of the compounds measured 1n the visitors' lounge during the third
day of monitoring. Data from the other locations are missing from this
time period and, hence, that time period was not used when testing for
concentration differences between sampling locations.
Summary statistics for the third trip to the new hospital are given in
Table 65. With the exception of indoor concentrations of 1,1,1-trichloro-
ethane, there were only small differences between the mean and median
concentration values. Highest mean Indoor concentrations were reported for
1,1,1-trichloroethane (15.5 ng/L), j)-dichlorobenzene (6.61 ng/L),
m,p_-xylene (9.91 ng/L), o-xylene (3.07 ng/L), and ethylbenzene (2.88 ng/L).

By the third trip, which took place ten months after occupancy, indoor
air concentrations for all compounds except n-decane had increased above
those detected for the second trip. Tetrachloroethylene and p_-dichloro-
benzene were detected for the first time indoors with rather high levels
reported for the latter. These increased levels of volatile organics can
be attributed directly to activities in the occupied building. These would
include both cleaning and general patient care activities. For example,
2-dichlorobenzene is probably resulting from bathroom deodorants. Outdoor
levels of volatile targets were generally low with little variation over
the three monitoring trips.
Results in Table 68 list mean indoor/outdoor concentration ratios for
the three trips and show trends similar to those discussed above.
New Office—
Trip 1. Concentration data for volatile organics measured during the
first trip to the new office (January 1985) are given in Tables 69 to 72.
Concentration averages and standard deviations for the 3-day period are
also given. This trip to the office was performed immediately prior to
occupancy. Finishing activities including painting, carpeting, wall-
papering, etc. had been performed within the 2-week period just prior to
monitoring. The generally very high levels of volatile organics found in
the building were probably a result of outgassing from the new building
materials. This, in fact, was confirmed during the emission study
described in Section 8. During day 1 of the monitoring period, cove
molding was being removed and reapplied using solvent-based products. This
activity is probably responsible for the elevated levels of m.g-xylene,
o-xylene, ethylbenzene, 1,2,4-trimethylbenzene and the alkanes measured
during that time period. The day immediately prior to monitoring, the
bathroom in the monitoring area was being cleaned with industrial-strength
cleaners. This may be the source for elevated levels of 1,1,1-trichloro-
ethane, m-ethyltoluene, o-ethyltoluene, 1,2,3-trimethylbenzene, and 1,3,5—
trimethylbenzene detected during the first night of monitoring.

The average concentration values for each of the preceding tables are
summarized 1n Table 73. Generally, comparisons of average Indoor concen-
trations using an F-test Indicated a uniform distribution throughout, with
no significant differences between monitoring locations. 1,2,4-Trimethyl-
benzene and n-rdodecane showed a significant difference at the 0.05 level
between mean concentrations found 1n office R-l and office R-7. Highest
concentrations were found 1n office R-7. 1,2-ECD was not detected 1n
Office R-7, but 1n the other two offices.
Table 74 gives summary statistics calculated for the first trip to the
new office. Mean, median, and maximum concentrations were determined.
These statistics are given for indoor and outdoor samples separately.
Indoor/outdoor ratios for the mean, median, and maximum concentrations have
also been calculated. With the exception of 1,1,1-trichloroethane, there
were only small differences between mean and median concentrations. This
Indicates that the data were not skewed toward either high or low concen-
tration values. Indoor concentrations for many aliphatic and aromatic
hydrocarbons were high (>20 ng/L). Highest Indoor concentrations were
measured for the n-alkanes (152 to 436 ng/L), 1,2,4-trimethylbenzene (73.5
ng/L), ethylbenzene (51.3 ng/L), and m,p_-xylene (41.5 ng/L). The only
halogenated target detected Indoors was 1,1,1-trichloroethane (12.5 ng/L).
Mean outdoor concentrations for all target volatiles were low «5.0 ng/L)
with the highest mean of all volatile organics concentrations reported for
benzene (4.08 ng/L). A two sample t-test performed using the mean concen-
tration values showed significant difference at the 0.05 level between
indoor and outdoor concentrations for all compounds except benzene. Highest
indoor concentrations were found for the n-alkanes, although indoor/outdoor
concentration ratios for these compounds could not be calculated since
outdoor concentrations were below the quantifiable limits. Highest mean
indoor/outdoor concentration ratios were found for 1,2,4-trimethylbenzene
(35.86), ethylbenzene (34.40), and 1,2,3-trimethylbenzene (27.96). The
highest indoor/outdoor concentration ratio was detected for n-decane
(392.15).
Table 75 gives mean daytime and nighttime concentrations calculated for
indoor locations only. Day/night concentration ratios were also calculated
and are included in the table. Results indicate that there were only small
differences between daytime and nighttime Indoor concentrations measured

during this field monitoring trip. Only n-propylbenzene and m-ethyltoluene
showed significant differences at the 0.05 level. In both cases, nighttime
concentrations were higher.
Trip 2. Concentration data for Trip 2 to the new office (August 1985)
similar to that reported for Trip 1 are given 1n Tables 76 to 79. During
the first day of sample collection, a mimeograph machine In the vicinity of
the monitoring area was 1n constant use. This could be the source of
elevated levels of benzene, l,2-d1chloroethane, 1,1,1-trichloroethane,
trlchloroethylene, n-butyl acetate, 2-ethoxyethylacetate, and tetrachloro-
ethylene detected on the first day.
Average concentration values plus standard deviations calculated for
each monitoring location are summarized 1n Table 80. Comparisons of
average concentrations at each Indoor location using an F-test showed a
uniform distribution with no significant differences at the 0.05 level
between indoor monitoring locations.
Table 81 gives summary statistics for this second trip to the new
office. Where measurable levels were found except for benzene, mean
concentration values for indoor samples were significantly (0.05) higher
than for outdoor samples. Highest mean Indoor concentrations were found
for 1,1,1-trichloroethane (38.85 ng/L), m,p_-xylene (15.05 ng/L), and the
aliphatic hydrocarbons (15.24 to 33.93 ng/L). For this trip to the new
office, n-undecane was the alkane with the highest Indoor concentration.
During the first trip, n-decane had the highest mean concentration. This
change in relative concentrations 1s probably a result of the more volatile
alkanes outgassing from building materials at a faster rate. This finding
was confirmed during our chamber study (Section 8). Highest mean indoor/-
outdoor concentration ratios were found for 1,1,1-trichloroethane (20.66),
1,2,3-trimethylbenzene (10.03), ethylbenzene (5.71), m-ethyHoluene, and
m,p_-xylene (4.84). Indoor/outdoor concentration ratios for the aliphatic
hydrocarbons were not calculated since outdoor levels were below the
quantifiable limit.
Table 82 gives mean daytime and nighttime concentrations calculated for
Indoor locations only. Day/night concentration ratios were also calculated
and Included in the table. Only n-butylacetate, benzene, trlchloro-
ethylene, tetrachloroethylene, and p_-dichlorobenzene showed significant
differences (0.05 level) between daytime and nighttime mean concentrations.

All compounds had higher daytime concentrations except n-decane. As
mentioned earlier, these target volatlles were probably emitted at high
levels on the first day as a result of mimeographing.
Comparison Between Trips. Data for volatile organic chemicals monitored
at the new office are compared between trips 1n Table 83, which gives mean
Indoor and outdoor concentrations for both trips, and Table 84, which gives
mean Indoor/outdoor concentration ratios by trip. The first monitoring
trip took place In January 1985, after the building had been completed and
before occupancy. Finishing activities, such as painting, wallpapering,
carpeting, etc., had been performed within the 2-week period just prior to
monitoring. The second monitoring trip took place seven months later in
August, 1985. The building was fully occupied and operational at the time.
Indoor air concentrations found during the first monitoring trip were
very high. Highest indoor air concentrations were found for the n-alkanes
(150-440 ng/L). The levels detected here were similar to levels detected
previously in a new, unoccupied office building (30). Elevated Indoor
concentrations (>15 ng/L) were also detected for m.jD-xylene, o-xylene,
ethylbenzene, m-ethyltoluene, 1,2,3-trimethylbenzene, 1,2,4-trimethyl-
benzene, and 1,3,5-trlmethylbenzene. As noted earlier, these indoor
concentrations are probably a result of the high emissions of volatile
organics from new building materials. Results of the emission study, along
with data from the building survey, suggest that carpet and carpet glue are
probably one of the major contributors to the indoor contamination levels.
With the exception of benzene and styrene, indoor air concentrations of
the aromatic hydrocarbons and n-alkanes were lower during Trip 2 than
Trip 1. The largest decreases 1n indoor concentrations were seen for the
n-alkanes. Not surprisingly, these compounds had the highest indoor
concentrations during the first monitoring trip. Lower indoor concentra-
tions during the second trip are most likely a result of lower emissions
from building materials, which had aged between the first and second trips.
In contrast, Indoor concentrations of the chlorinated hydrocarbons, the
oxygenated hydrocarbons, and c-pinene Increased between the first and
second monitoring trip. a-P1nene 1s generally emitted from wood products,
especially particle board. Between the first and second field monitoring
trips, all of the office furniture had been moved into the building and
would be the most likely source of a-pinene. General office activities,

Including mimeographing, are probably responsible for higher Indoor levels
of the chlorinated and oxygenated hydrocarbons. Mean outdoor
concentrations remained fairly constant between the two monitoring trips.
Results 1n Table 84 11st mean Indoor/outdoor concentration ratios for
the two trips and show trends similar to those discussed above.
New Nursing Home--
Trip 1. Concentration data for volatile organlcs measured during the
first trip to the new nursing home (February, 1985) are given 1n Tables 85
to 88. Concentration averages and standard deviations for the 3-day period
are also given. This trip to the home was performed prior to occupancy.
Construction and finishing activities (I.e., painting) had been completed
approximately six weeks before monitoring. The day prior to monitoring
some areas of woodwork were cleaned with mineral spirits and revarnished.
Cans of paint and solvent were being stored In offices one story below the
monitoring area. The cans were removed after the first monitoring period
(night 1).
The high indoor levels of volatile organics were probably a result of
outgassing from the new building materials. The levels found here were
lower than those found in the new office. This would be expected since
most materials in this building had been installed for a longer period of
time before monitoring (6 weeks versus 2 weeks). Indoor concentrations for
m,p_-xylene, o-xylene, styrene, ethylbenzene, 1,2,3-trimethylbenzene, and
1,3,5-trimethylbenzene were highest during the first monitoring period.
This could probably be attributed to varnishing activities. Alternately,
improperly stored solvents could also have been responsible. New wood
products are again the most likely source for a-pinene. The source of
2-ethoxyethylacetate is unknown.
Average concentrations of each target volatile at each monitoring site
are summarized in Table 89. Comparisons of average concentrations using a
F-test Indicated a uniform distribution throughout, with no significant
differences between monitoring locations.
Table 90 gives summary statistics calculated for the first trip to the
new home. Mean, median, and maximum concentrations were calculated for
Indoor and outdoor samples separately. Indoor/outdoor ratios for the mean,
median, and maximum concentrations are also given. With the e'captlon of

1,1,1-trlchloroethane and j>-d1chlorobenzene, there were only small differ-
ences between mean and median concentrations, Indicating that the data were
not skewed toward either high or low concentrations. A two-sample t-test
performed using mean concentrations showed significant differences at the
0.05 level between Indoor and outdoor concentrations for all of the
aromatic hydrocarbons except benzene, all of the aliphatic hydrocarbons,
trichloroethylene, p_-d1chlorobenzene, and 2-ethoxyethyl acetate. Highest
mean Indoor concentrations were found for the n-alkanes (31.42 to 68.51
ng/L), m,p_-xylene (23.80 ng/L), 1,2,4-trlmethylbenzene (13.95 ng/L), and
m-ethyltoluene (12.38 ng/L). Highest mean Indoor/outdoor concentration
ratios were found for 1,2,3-trlmethylbenzene (17.73), o-xylene (12.43),
m-ethyltoluene (13.60), and 1,2,4-trlmethylbenzene (12.57). Indoor/outdoor
concentration ratios could not be calculated for the n-alkanes because
outdoor levels were below the quantifiable limit.
Table 91 gives mean daytime and nighttime concentrations calculated for
Indoor locations only. Day/night concentration ratios were calculated and
have also been Included. In most cases, concentration differences between
daytime and nighttime samples were small. Only m,p_-xylene, ethylbenzene,
a-p1nene, trichloroethylene, and £-d1chlorobenzene showed significant
differences between daytime and nighttime concentrations. 1,1,1-Trichoro-
ethane showed higher daytime concentrations. Styrene, a-p1nene, trichloro-
ethylene, and p_-dichlorobenzene showed higher nighttime concentrations.
Trip 2. Concentration data for Trip 2 to the new nursing home (August,
1985), similar to that reported for Trip 1, are given 1n Tables 92 to 98.
Tables 92 to 95 give measured concentrations of volatile organlcs for
each location by time period. Mean concentrations and standard deviations
are also given. Concentrations of all the target volatlles that were above
the quantifiable limit increased during day 2. On this day, 1t began
raining and temperatures fell. Windows and doors that were open throughout
the building during the previous monitoring periods were closed. Although
1t was not possible to obtain acceptable air exchange data for the
building, one can assume that the air exchange rate decreased dramatically.
Under these circumstances, organlcs emitted from Indoor sources would
accumulate and Indoor concentrations would rise. To consider a second
explanation, the area next to the monitoring area was being refurnished.
Since different activities were performed each day, there could have been

some source of volatile organlcs Introduced during day 2. A1r mixing
between this area and the monitoring area was possible. Increased outdoor
concentrations could be due to a shift 1n prevailing winds during the time
period starting with day 3 (see Appendix A).
Average concentration values plus standard deviations calculated for
each monitoring location are summarized 1n Table 96. Comparisons of
average concentrations at each Indoor location using an F-test showed a
uniform distribution of organlcs with no significant differences at the
0.05 level between monitoring locations.
Table 97 gives summary statistics for this second trip to the home.
Although all Indoor concentrations were low, highest levels were reported
for m,p_-xylene (5.33 ng/L), n-decane (3.81 ng/L), n-undecane (3.48 ng/L)
and m-ethyltoluene (2.62 ng/L). Highest outdoor concentrations were
reported for m,p_-xylene (4.34 ng/L), benzene (3.40 ng/L), m-ethyl toluene
(1.78 ng/L), and 1,1,1-trlchloroethane (1.51 ng/L). With the exception of
styrene, Isopropylbenzene, n-decane, n-undecane, trlchloroethylene, and
n-butyl acetate, mean concentrations were not significantly different (0.05
level) between Indoor and outdoor samples. This 1s not surprising since
windows and doors were open during approximately one-half of the sampling
period. For all compounds, concentration levels were higher Indoors. Mean
Indoor/outdoor concentration ratios ranged from 0.72 for benzene to 1.51
for styrene. Only benzene and tetrachloroethylene had mean Indoor/outdoor
concentration ratios less than one.
Table 98 gives mean daytime and nighttime concentrations calculated for
the Indoor locations only. Most ratios ranged from 0.90 to 1.10. Benzene
had the highest ratio at 1.52. None of the compounds showed a signifi-
cantly difference at the 0.05 level between daytime and nighttime mean
concentrations.
Comparison Between, Trips. Data for volatile organic chemicals at the
new nursing home are compared between trips 1n Table 99, which gives mean
Indoor and outdoor concentrations for each of the three trips, and
Table 100, which gives mean Indoor/outdoor concentration ratios by trip.
This nursing home was essentially completed 1n January, 1985. The
first monitoring trip took place 1n late February of the same year with the
building still unoccupied. The second monitoring trip took place 1n
August, 1985, approximately five months after occupancy. One of the major

trichloroethylene. This difference could not be explained based on Infor-
mation collected at the building during field monitoring.
Table 106 gives summary statistics calculated for this trip to the old
office. Mean, median, and maximum concentration values were determined.
These statistics are given for Indoor and outdoor samples separately.
Indoor/outdoor concentration ratios for the mean, median, and maximum
concentrations have also been calculated, Results show only small differ-
ences between mean and median concentrations and Indicate that the data are
not skewed toward either high or low concentration values; an exception 1s
ethylbenzene, which showed higher mean values. 1,1,1-Trlchloroethane
(40.98 ng/L), m,p_-xylene (27.11 ng/L), and ethylbenzene (10.15 ng/L) showed
highest mean Indoor concentrations. m,£-Xylene (14.64 ng/L), 1,2,4-tri-
methylbenzene (6.99 ng/L), and benzene (6.62 ng/L) gave highest outdoor
concentrations. A two sample t-test performed using the mean concentration
values showed significant differences (0.05 level) between Indoor and out-
door concentrations for m,p_-xylene, o-xylene, styrene, ethylbenzene,
Isopropylbenzene, n-decane, n-undecane, 1,1,1-trlchloroethane, trlchloro-
ethylene, p_-dichlorobenzene, and 2-ethoxyethylacetate. For all compounds,
Indoor concentrations were higher. 1,1,1-Trlchloroethane (8.23) showed the
highest mean Indoor/outdoor concentration ratio.
Table 107 lists mean daytime and nighttime concentrations measured at
the Indoor sampling locations. Day/night concentration ratios are also
given. The day/night concentration ratios were highest for tetrachloro-
ethylene (1.94), n-butylacetate (1.77), 1,2,3-trimethylbenzene (1.42), and
£-dichlorobenzene (1.20), although only tetrachloroethylene and £-dichloro-
benzene showed significant differences (0.05 level) between daytime and
nighttime concentrations. In this building, the ventilation system was
turned off at night. Under these conditions, one would expect nighttime
concentrations to be higher (I.e., day/night ratios less than 1.00) for
constantly emitting sources. Only when there are sources specific to day-
time use would daytime concentrations be expected to be higher than night-
time levels.
Old Nursing Home-
Concentration data for volatile organlcs measured during field moni-
toring at the old nursing home are given 1n Tables 108 to 114.

Significant difference between daytime and nighttime mean concentration at the

Tables 108 to 111 give measured concentrations of volatile organlcs for
each location by time period. Mean concentrations and standard deviations
for the entire 3-day period are also given. No unusual occurrences of
chemical emissions were observed Indoors. Likewise, data showed no
discernible trends over the 3~day monitoring period. Malathlon was sprayed
on trees shrubs and the lawn surrounding the building on the third day.
This activity did not appear to Increase outdoor levels of volatile organic
compounds during that time period.
The average concentration values from each of the preceding tables are
summarized 1n Table 112. Comparisons of average concentrations between
Indoor locations showed significant differences at the 0.05 level only for
n-decane and n-undecane. Concentrations were highest 1n the unoccupied
apartment.
Table 113 gives summary statistics calculated for this trip to the old
nursing home. Mean, median, and maximum concentrations were determined.
These statistics are given for Indoor and outdoor samples separately.
Indoor/outdoor ratios for the mean, median, and maximum concentrations have
also been calculated. Results showed only small differences between mean
and median concentrations Indicating that the data were not skewed toward
either high or low concentration values. 1,1,1-Trichloroethane was an
exception showing higher mean concentrations.

(2.95 ng/L) showed high Indoor concentrations. The same three compounds
also had highest outdoor concentrations (1.28 to 3.03 ng/L). A two sample
t-test performed using the mean concentration values showed significant
differences (0.05 level) between Indoor and outdoor concentrations for the
xylenes, styrene, ethylbenzene, 1,2,4-trimethylbenzene, n-decane,
1,1,1-trichloroethane, and tetrachloroethylene. In all cases, Indoor
concentrations were higher. 1,1,1-Trichloroethane (2.41) showed the
highest indoor/outdoor concentration ratio.
Table 114 lists mean daytime and nighttime concentrations measured at
the Indoor sampling locations. Day/night concentration ratios are also
given and ranged from 0.76 for 1,2,4-trimethylbenzene to 1.28 for tetra-
chloroethylene, Indicating only small differences 1n daytime and nighttime
concentrations for all targets with measurable levels. ji-Ethyltoluene,

1,2,4-trlmethylbenzene, and tetrachloroethylene showed significant differ-
ences between daytime and nighttime Indoor concentrations. Only
tetrachloroethylene gave higher daytime concentrations.
Old Office/School —
Concentration data for volatile organlcs measured during field moni-
toring at the old office/school are given 1n Tables 115 to 12K
Tables 115 to 118 give measured concentrations of volatile organics for
each location by time period. Mean concentrations and standard deviations
for the entire 3-day period are also given. The data showed several
noticeable trends throughout the monitoring period. For example, the
xylenes showed highest Indoor concentrations during the first two moni-
toring periods, whereas n-decane and n-undecane showed highest Indoor
concentrations for the second and third monitoring periods. High levels of
halogenated hydrocarbons were detected 1n the third floor occupied office
throughout the monitoring period. Trlchloroethylene concentrations were
fairly steady throughout, whereas 1,1,1-trlchloroethane and tetrachloro-
ethylene showed highest concentrations during day 2 and night 3 of the
monitoring period. The cause for any of these Intermittent chemical
emissions could not be pinpointed. There was some painting the day prior
to monitoring 1n an area adjacent to the first floor renovated office and
the second floor unoccupied offices. Xerox machines were 1n operation
during each day near each of the sampling locations. General office
activities took place 1n the third floor occupied area. "White-out" was
used 1n this office during each daytime period and could be responsible for
elevated levels of chlorinated solvents.
The average concentration values for each of the preceding tables are
summarized 1n Table 119. Comparisons of average concentrations between
Indoor locations showed several Interesting trends. Most of the aromatic
hydrocarbons showed a uniform distribution with no significant difference
at the 0.05 level between monitoring locations. The n-alkanes showed
highest concentration at second floor unoccupied office, although this
difference was significant only for n-dodecane. e~Pinene showed lowest
levels at the first floor office. This would be expected since this office
contained little furniture, which appears to be the major source of
a-pinene 1n most buildings. In contrast, the third floor occupied ,.ffice

showed much higher levels of 1,1,1-trlchloroethene, trlchloroethylene, and
tetrachloroethylene than the other Indoor locations. Again this appears to
be due to general office activities taking place at that location. The
first floor renovated office generally had the lowest mean concentrations
compared to other Indoor monitoring locations. This was a surprise since
some painting and building activities had recently occurred at this moni-
toring site and we expected to find high localized concentrations of
volatile organlcs.
Table 120 gives summary statistics for this trip to the old office/-
school. Results for the aromatic hydrocarbons showed small differences
between mean and median concentration. The n-alkane and halogenated hydro-
carbons, however, showed higher mean concentrations. Apparently, higher
concentrations of the compounds detected at individual monitoring locations
was responsible for skewing the mean value upward. Highest indoor mean
concentrations were detected for trichloroethylene (10.89 ng/L), 1,1,1-tri-
chloroethane (10.69 ng/L), and m.fi-xylene (8.72 ng/L). Highest Indoor
median concentrations were detected for m,p_-xylene (8.56 ng/L), n-undecane
(5.43 ng/L), and 1,1,1-trichloreothane (4.80 ng/L). Highest outdoor mean
concentrations were reported for benzene (4.85 ng/L). A two sample t-test
performed using the mean concentration values showed significant differ-
ences (0.05 level) between Indoor and outdoor concentrations for all
compounds that were detected indoors, with the exception of benzene and
tetrachloroethylene. In all cases, Indoor concentrations were greater.
Highest mean indoor/outdoor concentration ratios were calculated for
trlchloroethylene (27.92), 1,1,1-trlchloroethane (4.97), and styrene
(4.26).
Table 121 lists mean daytime and nighttime concentrations measured at
the Indoor sampling locations. Day/night concentration ratios are also
given. Daytime/nighttime concentration ratios ranged from 0.71 for
a-pinene to 1.35 for n-decane. There were no significant differences
between daytime and nighttime concentrations at the 0.05 level.
Comparison Between Building Types--
Data for volatile organlcs are compared between buildings 1n Tables 122
to 124. Table 122 lists mean Indoor concentrations for target volatiles by
trip; Table 123 gives mean outdoor concentrations by trip; and Table 124

gives mean Indoor/outdoor concentration ratios by trip. Data 1n these
tables are summarized by compound class 1n Table 125. Several Interesting
trends are noted from these data.
1. The new buildings showed very high total levels of volatile
organlcs Immediately after construction (trip 1). These levels
decreased dramatically during subsequent field monitoring trips.
An exception to this trend 1s the new hospital; however, this
building was monitored eight months after completion and
presumably, during this time, the outgassing of volatile organics
from new building materials was no longer a significant source of
Indoor pollutants. Even 1n this case, the Indoor concentrations of
volatile organlcs decreased between the first and second monitoring
trips, suggesting that outgassing was still occurring even eight
months after construction.
2. The major Indoor contaminants 1n the new buildings monitored
Immediately after construction were the aliphatic organics. For
both the new nursing home and the office, these compounds accounted
for greater than 60% of the total mass of material quantitated.
Levels of the aliphatic hydrocarbons in existing buildings were
quite low, while mean outdoor concentrations were below the quan-
tifiable limit in all cases.
3. Although the aromatic hydrocarbons were ubiquitous, they were also
found in highest concentrations at the new buildings immediately
after construction. Trips 1 to the new nursing home and the new
office were the only trips where mean indoor/outdoor concentration
ratios were greater than five. Again, levels decreased substan-
tially by the second monitoring trip to each of these buildings.
4. Mean indoor concentrations for chlorinated hydrocarbons were
highest for the existing office buildings. Presumably, indoor
concentrations resulted from the use of solvent-based office
materials. Elevated levels of chlorinated hydrocarbons were also
found during the third trip to the hospital.
5. There appeared to be no discernible trends either for building type
or age of building for the oxygenated compounds.
Results from.Indoor^air-samples are summarized for each building type
by averaging data In^the following categories.

For the new buildings only the last monitoring trip from each site was
Included. This was done to minimize effects resulting from the outgassing
of building materials and to allow comparisons of activity pattern effects
1n each building.
These summarized results are given 1n Tables 126 to 128 for Indoor
concentrations, outdoor concentrations, and Indoor/outdoor concentration
ratios. These data show highest mean Indoor concentrations for the offices
for all compound classes. Highest mean Indoor/outdoor concentration ratios
were found 1n the hospital for the aromatic, aliphatic, and chlorinated
hydrocarbons. Highest Indoor/outdoor concentration ratios for the
oxygenated compounds were found In the offices. In fact, this was the only
building type where oxygenated compounds were detected. Both the offices
and the hospital appear to have Indoor sources for the chlorinated organics
which would be responsible for the elevated levels compared to outdoor air
samples. Indoor levels of volatile organics showed only small Increases
compared to outdoor levels 1n the nursing homes for all target chemicals.
NITROSAMINES
Sample screening analysis for a single sample from each location was
performed for all monitoring trips. During this screening, only n-nitroso-
morpholine was detected In any samples and, for this compound, only in
samples from the old office building. All samples collected from this
building were then analyzed. Again, only n-n1trosomorphol1ne was found.
Table 129 lists reported concentration levels for this pollutant for each
sample collected In the office. Results showed detectable levels in most
indoor samples with none found outdoors. Concentration levels did not
appear to vary between sampling locations. Data 1n Table 130 are mean
Indoor concentrations calculated for n-n1trosomorphol1ne 1n daytime and

nighttime samples. There appears to be higher concentration In the night-
time samples, although the reason for this 1s unknown. This office
building contained a fast food restaurant on the ground floor and a cooking
odor could be detected throughout. Cooking at the restaurant could be a
possible source of nitrosamines throughout the building.
MISCELLANEOUS VOLATILES AND ACRYLONITRILE
After consultation with the EPA Project Officer, samples collected for
miscellaneous volatiles and acrylonttrile were not analyzed.
PESTICIDES/PCBs
Sample screening, which consisted of analyzing a single sample from
each location, was performed for nine out of ten field monitoring trips.
Because screening results did not show elevated levels of pesticides (>10
ng/m3) in greater than 25% of the samples, no further analyses were
performed. The single exception to this protocol was made for the first
trip to the old nursing home. Here, Malathion had been sprayed around the
outside of the building during the third day of monitoring, hence, all
samples from this trip were analyzed.
To initially look at the data, we calculated the percentage of air
samples that had concentrations reported above the quantifiable limit.
This statistic, referred to as percent detected, was calculated for both
indoor and outdoor air samples collected during each field monitoring trip.
Results for percent detected given in Table 131 indicated a-, /?-, and 7-BHC
were the most frequently detected compounds. Although tech.-chlordane was
not found above the quantifiable limit in most cases, it was often detected
at trace levels.
Concentration data for pesticides/PCBs measured during each field moni-
toring trip are given 1n Tables 132 to 144. Concentrations are reported
for each location by time period. With the exception of Malathion found
during day 3 at the old nursing home (Tables 141 to 144), only low levels
of target pesticides/PCBs were found. No conclusions were drawn from these
results due to limited amounts of data.
Table 145 shows reported pesticide usage for each of the buildings
monitored. Chlorpyrifos was used 1n several buildings, but was not
recovered from field controls. Data from Lewis et al. (24) showed similar

problems with poor recovery during storage. Although Dlazlnon was to be
used at the new office, 1t had not been applied prior to either field moni-
toring trip. None of the other target pesticides were used 1n any of the
monitored buildings. Based on usage patterns, It 1s not surprising that
only low concentrations of pestlcldes/PCBs were found throughout this
program. Although It was not the mandate of this project, future work on
measuring these compounds 1n Indoor air should specifically be designed to
monitor for the pesticides actually 1n use, and samples should be collected
during or shortly after applications.
INHALABLE AND RESPIRABLE PARTICULATE MASS
Measured Inhalable (coarse) and respirable (fine) particulate concen-
trations for samples collected during this program are given in Table 146.
The table also gives a subjective measure of the amount of smoking that
took place at each location during monitoring. The increase in particulate
mass as a result of smoking was most noticeable for the old nursing home.
Heavy smoking in the TV lounge raised inhalable (coarse) particulate levels
slightly over the other Indoor location. However, respirable (fine) parti-
culate concentrations Increased from -16 to 45 /jg/m3 when compared to the
other two indoor locations.
Table 147 gives mean indoor and outdoor concentrations for each field
monitoring trip. Indoor/outdoor concentration ratios have also been calcu-
lated by trip and are listed. Very few trends are clear from these data.
For the new buildings, particulate levels appear to increase after
occupancy. An exception to this is the new nursing home; however, during
the second trip in August, the windows and doors were open throughout the
building during part of the time. This increased ventilation could have
helped reduce indoor particulate levels.
In areas where there was no smoking, Indoor concentrations were
generally lower than outdoor concentrations for both inhalable (coarse) and
respirable (fine) particulates. This 1s probably not surprising since all
buildings had mechanical ventilation systems that filtered the indoor air
and, hence, should have reduced particulate levels, especially if specific
Indoor sources were not present.

POLYNUCLEAR AROMATIC HYDROCARBONS (PNAs)
Polynuclear aromatic hydrocarbons were not found in any samples. The
detection limits for the method was ~1 ng/m3 for individual PNAs. Results
indicate that much larger samples are required if measurements of PNAs are
desired for indoor locations where no specific sources exist such as wood
fireplaces or wood stoves.
METALS
Table 148 lists the metal samples that were submitted to the subcon-
tractor for PIXE analysis, as well as those that were actually analyzed.
Sample screening consisted of one sample collected at two indoor and one
outdoor monitoring locations. If screening analysis gave positive results,
then the remaining samples collected during that trip were submitted for
analysis. Information in Table 148 shows that many of the samples sent to
the subcontractor were never analyzed; therefore, only limited data are
available.
To initially look at the data, the percentage of air samples that had
concentrations reported above the quantifiable limit (QL) was calculated.
This statistic, referred to as percent detected, was calculated for both
indoor and outdoor air samples collected during each field monitoring trip.
QLs for each trip are listed in Table 149. For the hospital (new), trip 3,
and the nursing home (new), trip 2, larger sample volumes were collected;
hence, a substantially lower QL was achieved for these two trips. Results
for percent detected given in Table 150 indicate that nickel, bromine, arid
lead were detected most frequently. Aluminum, selenium, and cadmium were
not detected in any samples.
Mean concentrations calculated for the six metals detected during field
monitoring are given in Table 151. To calculate these means, one-half the
LOD was used for concentrations below the detection limit; the average of
the QL and the LOD was used for concentrations reported below the QL but
above the LOD. A comparison of indoor to outdoor mean concentrations show
higher levels found outdoors. Three exceptions should be noted to this
trend. Higher indoor concentrations were found for lead at both the new
nursing home, trip 2 and the old office/school. Higher indoor concentra-
tions of arsenic were found at the new hospital, trip 3.

FORMALDEHYDE
Results of formaldehyde analyses are given 1n Table 152 to 153. Table
152 reports the percentage of air samples that had concentrations reported
above the quantifiable limits (QL). This statistic, referred to as percent
detected, was calculated for both Indoor and outdoor samples collected
during each field monitoring trip. Results Indicate that Indoor samples
had higher percent detected values than outdoor samples. The new office
building, trip 2, and the old nursing home had highest percent detected
values.
Table 153 gives formaldehyde concentrations measured during field moni-
toring. Concentrations are reported for each location by time period for
each trip. Trip 2 to the new office showed highest indoor concentration,
as well as highest percent detected values. This observation correlates
nicely with the concentration data for a-pinene (see volatile organics
section), where concentrations were also highest. As with formaldehyde,
concentrations of a-pinene also increased between the first and second
field monitoring trips. Since both formaldehyde and a-pinene outgas from
particle board, we presume that both observations resulted from moving
office furniture Into the building between the first and second field moni-
toring trips. For the remaining buildings, no conclusions were drawn from
the results due to limited data.
RADON
Results of radon analysis for samples collected during this field moni-
toring program are given 1n Table 154. These results may be compared to
the following indoor radon levels:
Radon (pCi/L) Type of Level and Remarks
4.0 U.S. EPA target level regulation for homes built on
sites contaminated by uranium processing.
5.0 Bonneville Power Administration (U.S. Department of
Energy) level for remedial action 1n weatherized
homes.
8.0 National Council on Radiation Protection and
Measurements recommended level for remedial action
for continuous exposure.

20.0 State of Pennsylvania recommended level for early
remedial action.
One of the samples collected at the new office building, Office R-l,
trip 1 had levels greater than 4.0 pC1/L. A sample taken during the same
trip and a sample collected at the same location during trip 2 showed
levels less than 1 pC1/L. Given these results, we feel the 4.1 pCi/L
reading should be viewed with caution.
AIR EXCHANGE
In parallel with sampling air for target pollutants, 12-hour air
exchange rate determinations were conducted by releasing sulfur hexa-
fluoride (SFs) Into the air.
In most cases, the analysis showed a linear relationship that allowed
the calculation of an air exchange rate. Where linearity could not be
established, a calculation was not made. This was, In fact, the case for
the second trip to the new nursing home. Here, the windows and doors were
open throughout the monitoring period, and Sf^ concentrations quickly
dropped below the detection levels, hence, no calculations could be made.
Results of air exchange measurements are reported 1n Table 155 for each
location 1n each building by time period. Average concentrations were
calculated for each trip over the entire measurement period as given in
Table 156. Daytime and nighttime average exchange rates were also calcu-
lated and included in the table. Average air exchange rates were generally
in the range 0.3 to 0.6 changes/h. The new hospital, trip 1, had the
highest exchange rate (0.94 changes/h), while trip 2 to the same building
(0.14) had the lowest. Noticeable difference between daytime and nighttime
air exchange rates were found for the new hospital trips 1 and 2, the new
office, trip 2, the new nursing home, trip 1 and the old nursing home.
Daytime air exchange rates were usually higher.
CARBON MONOXIDE
Field data generated using the Bendix Infrared CO monitors were
compiled for the four sampling locations monitored at the old office
building. Results In Table 157 are presented as 12-hour averages repre-
senting daytime (7 AM to 7 PM) and nighttime (7 PM to 7 AM) samples. No

NITROGEN DIOXIDE
Field data generated using the Bendix chemlluminescent monitors were
compiled for the four sampling locations monitored at the old office
building. Results in Table 158 are presented as 12-hour averages repre-
senting daytime (7 AM to 7 PM) and nighttime (7 PM to 7 AM) samples. No
general trends are noted in the data. Nitrogen dioxide was not monitored
on any other field trips.
ASBESTOS
Only one sample, that sample collected at the day room In the new
nursing home, had asbestos found above the detection limit. However, the
level found in this sample (284 flbers/m3) was Identical to the level found
in one of the field blanks. Because there was no known source of asbestos
in the building and because none of the other samples from this building
had detectable asbestos, the level detected here is probably an artifact,
although this cannot be confirmed.

SECTION 8
SOURCES OF VOLATILE CHEMICALS
INTRODUCTION
The purpose of this portion of the research program was to evaluate
volatile organic emissions from building materials and relate these data to
results of the concurrent field monitoring study.
The emission study was conducted in two phases. In the first phase,
preliminary headspace experiments were performed by placing the material to
be tested 1n a small glass jar and measuring the volatile organics emitted
using a dynamic headspace technique. The experiments were specifically
designed to give a fast, relatively inexpensive evaluation of emissions
from a large variety of building materials.
Based on the results of the preliminary headspace experiments, several
materials were selected for detailed emission studies using 12 L chambers
under controlled conditions of temperature, humidity, and ventilation.
Criteria for chamber testing included high emission of volatile organics
from the material; high surface area of the material in the building;
and/or unique emission of volatile organics from the material that were
also found 1n the building.
PROCEDURES
Collection and Storage of Building Materials
All emission testing was performed on materials used in the construc-
tion of a new single-story office building 1n Fairfax, Virginia. Most of
the 22 solid building materials tested were subsamples of the actual
materials used 1n construction and were collected at the sampling site in
January 1985. The remaining solid materials, plus the nine solvent-based
materials, were purchased from the manufacturer. Manufacturing lots were
matched where possible to materials actually used in the building. Table
-------
281
159 lists the materials tested and a description of specifications where
available.
Each of the solid materials collected at the building site were
temporarily stored «2 weeks) 1n Individual plastic garbage bags (Mobile
KorditeR large capacity 1.5 mil) 1n nonlaboratory areas at Research
Triangle Institute. For permanent storage, the materials were Individually
wrapped in heavy duty aluminum foil and placed in an outdoor metal storage
shed to minimize the potential for contamination from laboratory solvents
and chemicals. Samples were stored for a maximum of four months prior to
testing from January to April, 1985.
Solvent-based materials were stored in their containers as received.
Emissions Testing
Headspace Experiments-
Preliminary headspace experiments were performed to determine both the
Identities and approximate levels of volatile organic emissions from each
of the 31 building materials. For solid materials, one or two pieces (~2 x
4 cm) were cut from the material. The total surface area of each material
was accurately measured with calipers. For solvent-based products, the
material was first mixed, then applied with a Teflon spatula to one side of
a clean glass microscope slide (5.5 x 2.6 cm). The prepared slides were
allowed to dry at 23*C for seven days protected from both dust and
laboratory solvents.
During testing, the prepared sample material was placed in a wide-mouth
glass jar, which was sealed with a custom-built Teflon head. Dry, purified
nitrogen was introduced to the jar at 15 mL/min and allowed to vent for 60
to 90 minutes. After this equilibration period, a Tenax GC cartridge was
placed into the sampling head as Illustrated in Figure 9. For solid
materials, the headspace was purged through the sorbent overnight at 15
mL/min. Solvent-based materials were tested for -30 minutes. Blank
samples were collected from empty jars under identical conditions to assess
contamination. General conditions for the scouting experiments are given
1n Table 160. Detailed information on each material and test conditions is
given 1n Appendix E.

Chamber Experiments-
Based on the results of the preliminary headspace experiments, several
materials were selected for detailed emission studies using 12 L chambers
under controlled conditions of temperature, humidity, and ventilation.
Table 161 lists the materials tested 1n each chamber experiment. Both
solid and solvent-based materials were prepared as described for the
scouting experiments.
For each chamber experiment, a sample of material was placed 1n one of
four chambers and the chamber sealed. The ventilation rate was set and the
samples allowed to equilibrate overnight at 25*C and 48% relative humidity.
Purified air was supplied to each chamber at a rate of 0.1 l/min. From
each chamber 0.033 L/min of this air was removed by pumping through an
empty sampling tube, while the other 0.067 L/min was vented outside the
chamber. A fan blade attached to a magnetic stir bar provided thorough
mixing of the chamber atmosphere throughout the experiment. An individual
chamber is illustrated in Figure 10 and a schematic representation of the
chambers and air supply system 1s shown in Figure 11. After the equilibra-
tion period, Tenax GC cartridges replaced the empty sampling tube to
collect organic compounds from the gas stream. Chamber blanks were
prepared by leaving one of the chambers empty and collecting a sample of
the air from the empty chamber for 6 hours 1n order to detect background
contamination. Experimental conditions for the chamber study are
summarized In Table 160. Detailed Information on each material and test
conditions is given 1n Appendix F.
Chamber Validation—
An experiment was performed to evaluate recovery of target volatiles
from the test chambers by comparing concentration of volatile organics in
air collected with and without the chamber In line. The system mimicked
real emission sampling by providing a constant source of target volatiles
Into the chamber with sampling occurring under steady-state conditions.
For testing, twelve target volatiles were continuously Introduced Into
the test chamber at a controlled rate. This was accomplished by placing a
permeation tube for each compound 1n a glass mixing bulb maintained at
30*C. The glass mixing bulb was placed In-line with the humidified clean
air supply and allowed to equilibrate overnight. After equilibration,

three consecutive samples of the chamber air were collected on Tenax GC
cartridges. Once the samples were collected, the emission test chamber was
removed and replaced with a small glass splitter tube. After a one hour
equilibration period, three consecutive air samples were collected on Tenax
GC cartridges from the splitter tube. All collected samples were analyzed
by GC/MS.
Sample Analysis
Headspace Experiments--
Recovery of volatile organlcs from Tenax GC was accomplished by thermal
desorptlon and purging with helium Into a liquid nitrogen cooled, nickel
capillary trap. The vapors were then Introduced Into a high resolution,
fused silica gas chromatographlc column for component separation. Charac-
terization and quantltatlon of the constituents 1n the sample were
accomplished by electron Impact mass spectrometry. Quantitatlon was
performed by measuring the Intensity of the extracted Ion current profile.
Gas chromatography/mass spectrometry (GC/MS) conditions used during sample
analysis are presented 1n Table 16. Thirty-two target volatile organic
chemicals were quantitated 1n each sample (ng/cartridge) as described 1n
Section 6.
Concentrations in the chamber air (C) were calculated as:
C (ng/L) = ngT
volume sampled (L)
where ngy are the ng of each target found per cartridge.
Qualitative analysis was also performed on each sample. In order to
minimize the effort associated with Identifying each sample component,
chemical class Identifications were made for the alkanes and alkyl benzenes
by comparing single 1on chromatograms (SIC) to the reconstructed Ion
chromatograms (RIC) for a given sample. It was assumed, based on mass
spectral fragmentation patterns, that sample components with fragment Ions
at 119 and 134 were alkyl benzenes; similar Identifications were made for
the aliphatic hydrocarbons using fragment Ions at 57 and 71. Major
components 1n each sample that did not correspond to these two chemical
classes or that were not target chemicals were Identified by searching the
EPA/NIH data bases using an INCOS computer search alogrlthm.
-------
292
Chamber Experiments--
Tenax GC cartridges exposed during the chamber experiments were loaded
with -250 ng of bromopentafluorobenzene as an external standard, then
thermally desorbed and Injected Into a high resolution capillary column as
described above. Samples were analyzed by either GC/MS or GC/FID as
indicated on Table 161.
Procedures for GC/MS analyses and quantitation of the 32 target
chemicals are identical to those used for the headspace experiments.
Conditions for GC/FID analysis are shown in Table 162.
Quantitation of GC/FID results was accomplished using response factors
(RF). RF values for each target chemical were generated by analyzing
standard cartridges loaded with known amounts of targets (T) and external
standard (ES). RFs were calculated as:
RFT= V "9ES
AES- ngT
Aj 1s the peak area of target compound and ngj is the ng of target compound
injected into the GC/FID system. Likewise, AES and n9ES are tne Peak area
and amount injected of the external standard. The average RF was then used
to quantitate targets on sample cartridges from the peak area of the target
chemical. Sample concentrations were calculated as described above for
headspace experiments.
Target chemicals were Identified during GC/FID analysis by comparing
relative retention times for the samples and standards. For each material
tested, at least one exposed cartridge was analyzed by GC/MS. Comparison
of these results to GC/FID results assisted in positively identifying
target chemicals. Only those chemicals Identified at high levels without
chromatographic interferences were quantltated by GC/FID.

same amount (-250 ng) of standard was added to all cartridges, analytical
results may be normalized using peak height of the standard.
Quantitative results were used to estimate total emission rates of
target chemicals from each of the test materials. Under steady-state
conditions, the total emission rate of a chemical from a material should be
equal to its removal rate from the test chamber, and a simplified mass
balance equation can be used:
ET = CV x 1000
where Ey = total emission rate, /

of the building materials, although a number of compounds containing
oxygen, nitrogen and sulfur were tentatively identified through computer
searching. Unfortunately, qualitative analysis was often difficult since
spectra of these compounds did not provide a great deal of structural
information.
Based on the results of these preliminary headspace experiments, the
nine materials in Table 161 were selected for chamber testing. Criteria
for selection included high emission of volatile organics from the
material; high surface area of the material in the building; and/or unique
emission of volatile organics from the material that were also found in the
building. Results of the headspace experiments were also used for
selecting conditions for the chamber study (I.e., amount of material
tested, sample collection times, etc.).
Chamber Studies
Method Validation-
Table 169 shows levels of target volatiles found in chamber blanks.
Results show low levels of contamination for all target compounds.
Table 170 shows calculated recoveries from the chamber for the 12
compounds tested. Recoveries were calculated as:
% Recovery = TWC x 100%
TNC
where Tyc and TNC are tne measured amount of target volatile measured in
Tenax samples collected with and without the chamber in place. Results
showed high recoveries for all volatile organics tested.
Emission Studies—
Results of the chamber experiments are illustrated 1n Figures 16 to 24.
The external standard bromopentafluorobenzene, is designated on each
chromatogram as (*) and may be used to normalize analytical results as
described previously.
Emission rates were calculated from results of GC/MS analysis as
described for the preliminary headspace experiments. Table 171 lists
calculated emission rates for volatile organics from each material.
Reproducibility of chamber experiments was evaluated by calculating the
%RSD for , rates calculated for each material using replicate

determinations. Results listed 1n Table 172 show precision is good (%RSDs
less than 20%) in cases where the same experimental conditions were iden-
tical for all replicates. For cove adhesive, %RSDs varied from 19.3 to
47.3%. For this material, the replicate measurements were performed using
different surface areas. This was done to test for emission suppression
effects that might result from using a small chamber. The triplicate
determinations did show different emission rates with the highest rates
calculated for the smallest sample. Reduced emission for the larger sample
could result from suppression. Alternatively, the smaller samples had more
freshly cut surfaces. If the emission rate from a freshly cut surface is
higher than that of an older surface the same result of highest emissions
from the smallest sample would be achieved. No further experimental work
was performed to resolve this question.
DISCUSSION
Data 1n Table 171 and Figures 11 to 19 can be used to compare the
results of the preliminary headspace experiments to the results of the
chamber experiments. GC/MS chromatograms and calculated emission rates for
samples collected from vinyl cove molding, black rubber molding and poly-
styrene foam insulation showed very good agreement between the two evalua-
tions, suggesting that neither the emission testing conditions (I.e.,
ventilation, chamber size, humidity, or temperature), nor sample prepara-
tion techniques (length of storage, sample size, sample size to surface
area) had a significant effect on measured emission rates.
For the remaining three solid materials, namely linoleum tile, carpet,
and particle board, the emission rates calculated from the chamber study
were lower than those calculated during preliminary headspace experiments.
The GC/MS chromatograms for linoleum tile (Figure 15) and carpet (Figure
16) show that the more volatile or early elutlng compounds have disappeared
to a greater extent than the less volatile compounds. A likely explanation
for this 1s simply the aging of the materials. Chemical emissions usually
decay for most solid materials over a given time after manufacture, with
the more volatile components probably decaying faster. For the carpet and
linoleum tile, the scouting study was performed approximately six weeks
after the carpet was collected at the office building while the chamber
experiments took place approximately 16 to 20 weeks after collection.

Building material aging 1s likely to play an Important role 1n the emission
of volatile organlcs Into Indoor air.
For the particle board, emission of all chemicals appeared to decrease
1n the chamber experiments compared to the preliminary headspace
experiments. Since this behavior 1s different from that exhibited by the
linoleum and carpet, we assume the explanation may also be different. In
this case, reduced emission may be due to changes in temperature or
humidity between the two test conditions. This would be in keeping with
results from other reported emission studies for particle board that, show
different emission rates for formaldehyde depending upon test conditions
(30).
The three solvent-based materials showed very different emissions rates
between the two studies. Here, the difference is probably due to the way
materials were prepared for testing. Conditions that could affect the
result include the amount of material applied to the slides and the
temperature, humidity, and time conditions for curing the material.
Temperature and humidity conditions during testing may also effect measured
emission rates. These results demonstrate that, for solvent based
materials, dramatically different emission rates may be measured depending
upon test conditions and that caution should be employed when reporting
emission rate data as well as applying these results to indoor air quality
models.
Results of our emission experiments may be compared to other similar
studies. Molhave evaluated 42 building materials for volatile organic emis-
sions and reported the distribution of emission rates for all 42 materials
(2). The average emission rate (grand mean) was 250 /

Table 174 gives the average concentration of volatile organics measured
1n the new office building. These results compare well with the results of
both the headspace and chamber experiments. For example, the aromatic
hydrocarbons which have the highest Indoor air concentrations (ethyl
benzene, m-ethyltoluene, and 1,2,4-trlmethylbenzene), generally show
highest emission rates from all of the building materials. High emission
rates for the n-alkanes are found for many of the Interior materials,
Including the carpet, linoleum tile, all of the plastic materials and the
solvent materials such as adheslves, paint, and caulk. All of these
materials could contribute to the high indoor air concentrations of
n-alkanes found 1n the office. Particle board 1s probably a major source
of o-pinene. Finally, at the time monitoring was being performed, vinyl
cove molding and cove adhesive were being applied throughout the building.
It is likely these materials are major contributors to ethylbenzene, and
the xylenes found in the air samples.

SECTION 9
ESTIMATED SOURCE STRENGTHS
The Inclusion of air exchange measurements 1n this Indoor air study
allowed us to estimate source strengths at each Indoor location. The esti
mates were based on very simple Indoor air models using the following
equation:
where C * mean concentration (/jg/m3) averaged over all monitoring
periods,
S = mean source strengths per unit volume per hour (/ig/h/m3),
a = mean air exchange rate (h~).
This equation may be rearranged to:
S = * (C1n-Cout).
Monitoring data are available for all terms on the right-hand side.
The source strengths calculated 1n this manner should be considered
rough approximations for two reasons:
1. Measured air exchange rates Included infiltration from both the
outside air and air 1n other parts of the building which were not
spiked with Sf$. Measurements taken 1n this manner could be higher
than those determined from Infiltration of outdoor air only.
Hence, 1t 1s possible for both air exchange rates and calculated
source strengths to be overestimated.
2. In all cases, It was assumed that pollutant decay rates were zero.
Since this 1s not always true, the calculated source strengths are
probably underestimated for pollutants such as partlculate mass,
metals, N02, and formaldehyde.
-------
329
Results of source strength calculations for volatile organlcs are given
In Tables 175 and 176 for mean and maximum source strengths calculated for
each target chemical for each field monitoring trip.
Trends for the source strength data are very similar to the trends
noted for the concentrations of volatile organics (see Section 7). To
reiterate:
1. New buildings showed high source strengths for volatile organics
immediately after construction (trip 1) that decreased during
subsequent field monitoring. Even the new hospital which was moni-
tored for the first time eight months after complete showed
decreases in source strengths between the first and second trip.
2. In the new buildings, the aliphatic organics had the highest source
strengths. On the other hand, source strengths for these compounds
were quite low in existing buildings.
3. Highest source strengths for aromatic organics were also found in
the new building.
4. Source strengths for chlorinated hydrocarbons were highest in
occupied office buildings.
5. There was no trend for source strengths of oxygenated compounds.
Calculated source strength for a-, /?-, and 7-BHC are given in Table
177. These were the only three pesticides detected in a sufficient number
of indoor and outdoor samples for meaningful calculations. Source
strengths were low for all three of these compounds.
Calculated source strengths for the remaining chemicals detected during
field monitoring are given in Table 178. In most cases, the mean outdoor
pollutant concentration was higher than the mean indoor pollutant concen-
tration indicating no indoor sources. For selected field monitoring trips,
indoor sources for particulates, formaldehyde, carbon monoxide, and
nitrosomorpholine were found.

SECTION 10
QUALITY ASSURANCE/QUALITY CONTROL
Quality control and quality assurance activities were an integral part
of this research program. The work was carried out by following those
principles set forth in the U.S. Environmental Protection Agency's "Quality
Assurance Handbook for Air Pollution Measurement Systems" and specifically
applied to this study through the "Quality Assurance Project Plan for Moni-
toring In and Around Public Access Buildings."
This section summarizes quality control and quality assurance
activities that took place throughout the project including:
• Preparation and revision of a quality assurance project plan;
• Performance audits using EPA GC/MS Performance Evaluation Samples
and other traceable standards;
• Systems Audits including pretrip checks and progress updates;
• Communications with the EPA QA Officer; and
• Analysis of QA/QC samples.
Each of these aspects is discussed below.
QUALITY ASSURANCE PROJECT PLAN
*
A quality assurance project plan was prepared for this project. It
discussed the technical and managerial aspects of the works and contained
plans that satisfied the fourteen points specified in the EPA Publication
QAMS-005/80, "Interim Guidelines for Preparing Quality Assurance Project
Plans." Certain sections of the plan were revised in accordance with
requests and comments from EPA. These revised sections were submitted to
the EPA Quality Assurance Officer.
PERFORMANCE AUDITS
A number of internal audits were conducted to ensure that sampling
equipment for use at the field sites, and analytical equipment, for use in
-------
335
analysts of collected samples, were 1n proper working order and within
calibration limits. For example, the flow rates of the filter and
cartridge sampler assemblies were checked with soap film flowmeters and
calibrated rotometers. Calibration and performance records of all analy-
tical systems were checked and verified routinely.
Another aspect of the internal audit program was the distribution and
analysis of EPA-provided GC/MS performance evaluation samples. These
samples were prepared by a contractor to EPA, Northrop Services, and
provided to RTI on a periodic basis through the EPA Quality Assurance
Officer. The scheduling of the preparation and use of the samples was such
that no more than 4 weeks elapsed between their preparation by gravimetric
spiking on Tenax GC cartridges and their analysis by RTI. Results were
compiled, checked for accuracy, and submitted to the EPA QA Officer as soon
as possible after analysis of samples from a single field monitoring trip
so that any apparently out-of-tolerance results could be investigated and
necessary corrections made before the next set of samples was analyzed.
Blank samples were also included 1n this program.
Accuracy and precision for the GC/MS performance evaluation samples are
given in Table 179. Accuracy is evaluated as % recovery where
% Recovery = Xfound X 100%
Xspiked
where X is the mass of each Individual analyte. Precision is evaluated as
standard deviation. Quantile recoveries are also given.
Overall, the results indicate a slight negative bias for all analytes
(% recovery less than 100%) with standard deviations ranging from 19 to
46%. 1,2-Dichloroethane and 1,1,1-trichloroethane showed the best
precision. Highest standard deviations were reported for carbon tetra-
chloride; however, this analyte was not detected at a significant level in
any samples and quantitation data has not been presented.
No other performance evaluation samples were submitted by EPA for
analysis.
SYSTEMS AUDITS
Systems audits, designed to show RTI's ability to collect samples and
conduct analyses were conducted on several occasions throughout the

project. The RTI Project Quality Assurance Officer conducted these quali-
tative audits by examining the written standard operating procedures for
sample collection and analysis, by Interviewing the responsible analyst or
supervisor, and by visiting with the EPA QA Officer and the RTI Project
Leadership. Details of the audits are discussed 1n Section 10 of the QA
Project Plan.
Analytical Laboratory Systems Audits
The GC/MS, GC, and field support laboratories were visited several
times during the project. The SOPs and data records were examined and
discussed. These visits and Interviews demonstrated that SOPs did exist,
were in the hands of the responsible analysts, and were being followed.
The need for updates and revision to several of these documents was noted.
These updated documents were prepared.
Another aspect of the laboratory systems audit was to meet with the RTI
project leader from time to time to check on the progress of scheduled
analyses. Whenever scheduling difficulties were noted, goals were set for
rectifying these off-schedule situations both at RTI and at subcontractor
laboratories.
Field Operations Systems Audits
Prior to several of the field monitoring trips, the RTI QA Officer met
with the field sampling team to survey and discuss their state of readiness
for the trip. A checklist was used to assess the status. Important items
covered 1n these systems audits included
• readiness of collection equipment and filters; calibration status
of flowmeters and rotometers;
• cleanliness of formaldehyde collection materials;
• readiness of meteorological equipment; availability of infield or
laboratory cross-checks for proper operation;
• readiness of continuous analyzers for carbon monoxide and oxides of
nitrogen analysis;
• quality control and storage status of Tenax cartridges; and
• availability of field and laboratory control samples for all sample
matrices.
-------
338
Most often the field sampling team and their equipment were found to be
In a state of readiness. Any exceptions noted were discussed with the
Project Leader who took action to ensure that preparations were complete
before sampling began.
COMMUNICATIONS WITH EPA
Quality control and quality assurance Information was communicated to
EPA 1n several ways:
• Through preparation of data reports of results of EPA GC/MS
Performance Evaluation samples;
• Through meetings held with the EPA QA Officer to discuss the
performance evaluation samples;
• Through walk-throughs and Inspections of RTI laboratories.
QUALITY CONTROL/QUALITY ASSURANCE SAMPLES
Blanks and Controls
In an effort to assess accuracy and precision for measurement para-
meters, quality control samples were prepared and analyzed as described In
Sections 4 and 6. Analytical results for control and blank samples are
presented and discussed In Section 6. Table 180 Indicates where data for
specific analytical procedures can be found. This table also summarizes
results for control and blank samples.
Duplicates
In an effort to assess method precision, duplicate field samples were
collected and analyzed. Data in Tables 181 to 188 present results of these
duplicate analyses for nitrosamines, pesticides/PCBs, particulate mass,
metals, carbon monoxide, formaldehyde, radon, air exchange. Results have
been given only for target chemicals that were actually detected in both
samples. Precision was evaluated as percent relative mean deviation (%
RMD) calculated as
% RMD =
x 100%
X
where S 1s either sample value of the duplicate pair and jf Is the mean
value for the duplicate pair.

Most analyses showed acceptable precision (I.e., 00%). Some duplicate
samples for metals and radon showed poorer precision. Duplicate results
for carbon monoxide analysis showed very poor agreement especially at the
1 ppm level. This 1s not surprising since the instrument can show a drift
of +1 ppm. In Table 185, it is interesting to note that the trend for
highest CO concentrations in sample 614-3 and 614-5 was noted for both
monitors.
All samples for volatile organics were collected in triplicate using
distributed air volumes. All collected samples were analyzed and the mean
and standard deviations calculated for colocated samples. The % relative
standard deviation for the triplicates was then calculated to assess
precision, where % RSD = Standard Deviation/Mean X 100%. Table 189 gives
the mean %RSD for each target volatile that was detected in more than five
samples. %RSD values, which represent the 25th, 50th (median), 75th, and
90th percentile, have also been included. Results show good precision for
most analytes with median %RSD values generally between 10 and 20%.
Quality Assurance Samples
Ten percent of the samples for volatile organic analysis were collected
in quadruplicate. In these cases, three of the samples were analyzed at
RTI and one sample was sent to an independent QA laboratory for analysis.
The QA laboratory performed quantitative analysis for fifteen of the
target volatiles in these samples Including 1,2-dichoroethane, 1,1,1-tri-
chloroethane, benzene, carbon tetrachloride, trichloroethylene, tetra-
chloroethylene, chlorobenzene, ethylbenzene, c-pinene, 1,3,5-trimethyl-
benzene, ri-decane, o-dichlorobenzene, o-cresol, n-undecane, and n-dodecane.
Four of these compounds, carbon tetrachloride, ethylbenzene, o-dichloro-
benzene, and o-cresol, were not detected in any samples. For the remaining
compounds, between-laboratory variability was estimated by calculating the
% relative mean deviation (%RMD) for duplicate measurements. Data for
these replicate samples are given in Table 190. %RMD values show generally
acceptable precision between laboratories. Levels reported by RTI were
generally lower than those reported by the QA laboratory. Lowest mean
%RMDs, and hence best precision, were reported for ethylbenzene and 1,3,5--
trimethylbenzene. Highest mean %RMDs were reported for 1,1,1-trichloro-
ethane and trichloroethylene.

It is the understanding o-t Pierce Architecture that the LI. 5.
Environmental Protection Agoni-v (EPA) and it's contractor.
Research Triangle Institute tRT]), intend to monitor the indoor
air in specified i-paces and the cutdoor air at the Hospital and
Domiciliary facilities. I.-idaor aptxces to be mjnitared in the
Hospital include a patient care- roam, a nurses' station end a
lounge, each served by a ccrmiion cu'iside air intal-e. These spaces
would be monitored on multi:»1e occasions to re-fleet corditiors
prior to initial occupancy and at -.crying stages a-fte-r occupancy.
Indoor spaces to be monitored «t tr.a Domiciliary include a single
living unit, a multiple living unit, and a lounge, esch served by
a common outside air intate. Th? Domi ri 1 i ary i= to be monitorf?d

BASIS OF THIS REPORT
The analysis prepared by Pierce Architecture is intended to
identify the buildings' design and operations which are expected
to have an appreciable effect on the air movement in the spstces
to be monitored, and is in response to data needs indicated in
the RTI prepared Building Questionnaire, dated March 1937 and
revised May 1983, Form #2. Specifically included is that data
sought by questions 3a, 3b, 4, 5 and 6 of Part A, and la, 3b, 2a,
2c, 3, 4, 5a, 5b, 6a, 6b, 6C, 6d, 6e, 7, 9 and 10 of Part I", &s
expressed in a meeting between representatives of ths EPA, RTI,
National Institute of Building Sciences (NIPS) and F'i erte
Architecture on 14 March 1984; and as expressed by
representatives of the above organizations at the building site?s
on 29 May 1984.
The basis of the analysis has been:
1. Drawings and Specifications for the 357 Bed Rc?p3 ac.t?msnt
Hospital "dated 4 June 1980, prepared for the Veterans
Administration by Gates/LBC?.i. i c.r.

The Nurses' Station is open on three sides to the "race-* r-u.i "
corridor system, although a 42 inch high counter and a t,hnrt
valence at the ceiling define the perimeter of the space?. The
valence plus a return air grille within the Nurses* Station ap^ce
could to some degree contain air within that space, howe-ver some
turbulance could be expected from the more negative pressure in
the corridor system and occupant activity.
There is no additional -filtration or air cleaning at the pMitr.t
room areas, although during occupancy, such devices at "B.TIO^ t<
eaters" could be temporarily located in spaces such as the.' Der/
Room. Ely policy, the Hospital administration intends to restrict

ately thereafter.
PROPOSED INDOOR AIR QUALITY TESTING
It is the understanding of Pierce Architecture that the U.S. Environ-
mental Protection Agency (EPA) and its contractor, Research Triangle Insti-
tute (RTI) intend to monitor the indoor air in specified spaces and the
outdoor air at this facility. Indoor spaces to be monitored include private
offices, large group offices, and small conference rooms, all located in a
common area of the building. These spaces would be monitored on multiple
occasions to reflect conditions prior to initial occupancy and at varying
stages after occupancy.
BASIS OF THIS REPORT
The analysis prepared by Pierce Architecture is to identify the build-
ing's design and operations which are expected to have an appreciable
effect on the air movement in the spaces to be monitored and is in response
to data needs indicated in the RTI Building Questionnaire, dated March
1983, and revised Hay 1983, Form #2. Specifically, that data sought by
questions 3a, 3b, 4, 5, and 6 of Part A, and la, Ib, 2a, 2c, 3, 4, 5a, 5b,

BUILDINGS OPERATIONS ANALYSIS FOR BUILDING "B"
FAIR OAKS CORPORATE CENTER, FAIRFAX COUNTY, VIRGINIA.
DESCRIPTION OF THE FACILITY
Building "B" is one of five single-story buildings in close proximity,
forming a portion of the Fair Oaks Corporate Center.
The building is in excess of 32,000 square feet of floor area. The
"West" wing, suggested for the indoor air monitoring site and contained
within a single smoke separation zone from the balance of the building, has
an area of approximately 7,900 square feet. The building has a constant
ceiling height of 9 feet, producing an approximate volume of 71,100 cubic
feet in the West wing, The roof structure slopes on a 2 in 12 pitch, with
-------
407
•n average height of 6-1/2 feet between tb^ ceiling and the roof deck, for
an approximate volume of 51,350 cubic feet above the West wing.
The heating, ventilating, and air-conditioning (HVAC) system consists
of multiple small capacity electric heat pumps, located throughout the
Jbuilding. Each serves an area of 1,500 to 2,000 square feet, has an individ-
ual outside air intake, and has a return air intake located in a corridor
partition or ceiling. As a result of the limited capacity, no single HVAC
unit supplies all of the types of spaces intended for the indoor air testing.
The Vest wing has been suggested for the 'testing site, as it does contain
the desired space tenant occupant activities, and the HVAC units' outside
air intakes are in close proximity. HVAC units No. 10 and 12 have outside
air intakes through the roof, and No. 11 is located in a building perimeter
soffit.
It has been observed and noted to the EPA and RTI representatives that
some soffit air intakes are located near a soffit mounted toilet exhaust
grille (not the case with No. 11). It has also been pointed out that
exhaust fans for the large conference room (not in the West wing), which
contains a cooking demonstration center, distribute return air directly
into the plenum above the ceiling, and could be subjected to drift into the
return air of several HVAC units serving other areas.

DESCRIPTION OF THE FACILITY
The Belfer Center fs a five story building of staggered levels, generally
"L" »haf>ed In plan, with two story lecture rooms at the apex of the "L".
The floor plan Is divided Into three zones (each leg of the "L" and the
central Lecture Room spaces), separated by partitions extending through the
suspended ceilings to the deck above. Air fs supplied to and returned from
the central spaces by air handling units serving both legs, creating a
potential for cross mixing of air from one leg (zone) to the other. The
spaces designated for testing are contained within a single leg.
The building contains approximately 42,000 gross square feet of area and
456,730 cubic feet of volume. Celling heights vary throughout the build*
Ing, and are stepped In the tiered floor Lecture Rooms.
Toilet exhausts and emergency generator exhausts are located at the roof
level, and therefore should not affect the ground level air Intakes.
Landscaped planters are located In front of each of the two ground level
air Intake louvers.
The building Is attached to an adjacent part of the School of Government
which was constructed several years earlier. There Is no attached garage.
Hlcro computers and printers are In abundant use throughout the offices.

The following conditions will exist during normal night and weekend
hours without scheduled activities!
Both air handling units will be off.
The dampers In the ductwork will be closed.
The VAV boxes will be off.
The toilet exhaust fans will be off.
The outside air exhaust air dampers wHl go to the normal fully
closed position.
Supply and Return Air Controls Economizer
With the outside air at winter design temperature, the outside air
Intake damper Is set to 81 outside air (the minimum allowed per the
mechanical drawings) end the damper controlling the exhaust Is
closed. The return air damper, which controls the amount of the
building's Indoor air to be reclrculated. Is completely open. As
the outside air temperature Increases, the outside air damper grad-
ually opens to maintain the supply air temperature at 55 degrees
F. Return and exhaust dampers modulate to provide consistent air
flow Into and out of the building. Correspondingly, at summer
design temperatures, the outside air Intake damper closes at 82
degrees F. The outside air damper and the exhaust air damper are
completely closed when their respective supply fans are off.
Design conditions fn the designated test areas are:
Office 125 - floor area of this newly created room, which 1s not a
part of the architect's end the engineer's original design. Is
approximately 126 square feet. The celling height Is 9' 5-1/4",
providing a volume of approximately 1197 cubic feet. Air supply on
maximum demand Is 40 cfm of Introduced air from the VAV system and
300 cfm of rectrculated air from within the room through the
perimeter fan coll unit. Windows tn this space are fixed.
With the door closed, the design air changes per hour via the
mechanical ventilation system, would range from 0.4 to 2.0,
depending upon demand (CFM o,f Introduced air x 60/volume of room
« air changes per hour). The"number of air changes per hour of
outside air at winter design temperature would be approximately 81
of the air change rates noted above, the remainder Is reclrculated
building air from the VAV system. As the outside temperature
Increases, the percentage of outside air In each air change would
Increase to a maximum of nealy 1001 If the economizer cycle Is
operating and the outside temperature Is optimal, if outside
temperature Is too warm to permit operation of the economizer
cycle, the cooling cycle limits the Introduction of outside air as

Actual air changes In this room, resulting from Infiltration
through the operable window sections, the fixed window sections,
and other parts of the adjacent exterior envelope, would vary based
on the amount and length of time the windows ere open, the direc-
tion and velocity of the wind, the outside temperature, whether or

Cabinet untt heaters are located near the exterior doors to offset the
additional heat loss at those areas. These units are hot water type, with
a small reclrculatlng fan.
The Resident Rooms, Business Office and Gift Shop, and the Solarium are
heated using fin tube convection heaters, controlled by en Individual
room thermostat which regulates the flow of hot water through the fin
tube. The source of fresh air Is that provided by the unit ventilators
Into the Corridor or Lobby. Such air may be drawn Into rooms by the toilet
or utility exhaust fans (when present). Air from the unit ventilators can
enter these rooms through open doorways or by Infiltration around and under
doors.
In Resident's Room 208, the toilet exhaust fan Is designed to draw 45 cfm
of air Into the room, producing approximately 1.05 air changes per hour
(cfm x 60/volume of room * air changes per hour). This air can come from
Infiltration around door to the corridor, through open windows, by Infil-
tration through the exterior wall, or a combination of these routes.
Neither the Business Office nor the Gift Shop have air supplied direct
to them, nor Is there a toilet or utility exhaust to draw air from the
Lobby. These spaces, except at times when the windows are open, depend
on drift through open doorways or Infiltration around closed doors for
air change (ventilation).
The Lobby has a controllable mechanical exhaust, with rated capacity of 600
cfm. During operation, the unit ventilator serving the Lobby would operate
on 801 fresh air.
The Solarium depends on Infiltration or the opening of doors or windows for
outside air. Very little ventilation Is expected during periods when the
windows and doors are closed.

APPENDIX G
Analysis of Distributed Volume Tenax Samples
-------
705
All 216 Tenax samples were collected in triplicate at widely
ranging flow rates (sampling volumes of 7, 14, and 21L) . This
was done as a quality assurance device first suggested by Walling
(1984) to detect possible artifact formation or other problems
occurring during sampling. Concentrations that vary with
changing flow rate by more than the expected system precision
using true duplicate volumes would be "presumptive evidence" that
such problems were indeed occurring.
All cases in which measurable quantities of a compound were
collected by all three samples were analyzed. The geometric mean
concentrations of 29 compounds are listed for each of the three
sample volumes in Table 1. To test whether different sampling
volumes resulted in significantly different concentrations, the
logarithms of all concentrations were compared for the three
sampling volumes using a two-way analysis of variance. If the
null hypothesis (all three sampling volumes equivalent) was
rejected at the p<.05 level, pairwise comparisons were performed
to isolate the particular sampling volume or volumes that
produced significantly different geometric mean concentrations.
Only one chemical (benzene) showed a consistent significant trend
across all three sampling volumes, reading 10-15% lower with
increasing sample volumes. Other chemicals showed one or two
differences at the p<.05 level, but no consistent significant
trend was evident.
The relative standard deviations of the three geometric
-------
706
means are calculated for all 29 chemicals in Table 2.
Differences between geometric means were 10% or less for 25 of
the 29 compounds, another indication that varying the sample
volumes by a factor of 3 had little effect.
As an independent test of whether different volumes had
significantly different concentrations, a nonparametric test
(Friedman's chi-square) was employed. This test does not require
that the data be distributed normally, and is insensitive to
outliers or excessive differences in variance. Concentrations
for each triplicate sample were ranked (l=low, 3=high) and then
the mean rankings for each volume compared (Table 3) . The
results indicate that only 2 of 29 compounds showed consistent
and significant effects of flow rate on concentration: benzene
and m-cresol.
Some of the remaining 27 compounds showed differences in
concentration for one or another flow rate, but none showed
consistent trends that were statistically significant. Thus, we
conclude that for all compounds except benzene and m-cresol, the
different sampling volumes gave essentially similar results.
The effects of ozone, NO2, and humidity on Tenax have been
investigated (Pellizzari, 1977). Since the outdoor levels of
ozone and relative humidity can differ dramatically from indoor
levels, it is possible that outdoor Tenax samples could be
affected differently from indoor samples. If so, the precision
of the distributed volume samples might reflect the different
effects of indoor/outdoor conditions. To check this possibility,
we compared the precision of the indoor triplicate samples to
-------
707
those of the outdoor samples (Table 4). Only three chemicals—
benzene, styrene, and 1,2,3-trimethylbenzene--showed a
significant (p<0.05) difference, with the outdoor precisions
being worse than indoor in every case. The remaining 18
chemicals displayed no effect traceable to differences in
outdoor/indoor conditions. (Eight other chemicals had no
measureable concentrations in outdoor air.)
We conclude that for 25 of our 29 target chemicals, this
extensive effort at distributed volume sampling resulted in no
indications of chemical reactions or artifact formation during
sampling. Other quality assurance procedures had implicated m-
cresol as not providing trustworthy results. Only benzene,
styrene, and 1,2,3-trimethyIbenzene gave evidence of problems,
and these problems were all in the 5-15% range.
For future indoor and outdoor programs involving sampling
with Tenax, it is suggested that distributed volume sampling be
employed on a limited basis (perhaps at the beginning of the
program to test for any site-specific problems) rather than on
100% of all samples as in this program.
