ABSTRACT
This report describes the results of a three-phase study to investigate
the indoor generation of air pollutants. Both field and laboratory measurements
of nitrogen dioxide (NCL), nitric oxide (NO), and carbon monoxide (CO) were
made to evaluate the contribution of gas stoves to indoor pollutant levels. An
inventory of significant sources of indoor air contaminants was also made.
In the field program, four private residences with gas stoves were
selected for monitoring during the spring and fall of 1973. A two-week
measurement period at each residence for each season was utilized. Measurements
of the three pollutants were made at three indoor locations, the kitchen,
living room and bedroom as well as outdoors.
In order to sample at all four locations simultaneously and yet conserve
equipment and manpower, TRC designed and built a measurement system that
enabled the use of a single analyzer for NO,, and NO and a second analyzer for
CO. An electronic timer, solenoid valves and continuously purged teflon
sampling lines were used to permit the analysis of sample streams from each
location in rapid sequence.
The laboratory program was designed to evaluate the mass emissions from
both old and new stoves and also a small unvented space heater. The
effectiveness of vented and unvented kitchen hoods in removing gaseous pollutants
was also evaluated. A variety of stove operating modes were evaluated in
order to establish a relationship between operating conditions and pollutant
levels.
Two of the homes in the field program were surveyed to determine all
significant indoor sources of contaminants. Information from these two in-
depth surveys was used in surveying a broad range of TRC employees regarding
contaminant generating activities.

The results of this program show the concentrations of NO., NO, and CO
to which the occupants of residences are exposed, the variation of pollutant
concentrations within a structure, the relative magnitude of indoor generated
pollutants and oxitdoor pollutants which penetrate a structure, the influence
of stove operations upon the generation of pollutant quantities, and the
relative importance of contaminant sources other than gas appliances.

INTRODUCTION
The Research Corporation of New England (TRC) carried out a study
of indoor/outdoor air quality relationships for the forerunner of EPA, The
National Air Pollution Control Administration (Contract CPA-22-69-14). The
results of this study were published in the technical literature
and showed that indoor air quality is a complex function of outdoor pollutant
concentrations, building permeability, meteorological conditions, ventilation
system design and indoor generation of pollutants. While more work is
needed in establishing the specific effect of each of these factors on indoor
air quality, the one factor of those listed which is least understood and which
will assume greater importance as outdoor air quality improves, is indoor
generation of air contaminants.
In 1972, a conference was held at South Berwick, Maine on the subject
(3)
of improving indoor air quality. The meeting brought together a wide
range of scientists, engineers, and physicians concerned with the subject.
The meeting showed the complexity and high degree of interest in the entire
subject of indoor air quality. While indoor air quality in general appears to
be dominated to a great degree by outdoor air pollution, the indoor/outdoor
relationship is also a complex function of building permeability, type of
ventilation system, meteorological conditions and internal generation. An
especially important outcome of the meeting was the indication that internal

generation of pollutants is a more critical aspect of the problem than was
heretofore suspected. Gas stoves were implicated repeatedly as to their
potential emissions of CO, hydrocarbons, NO , odorous materials and
X
unspecified compounds that one doctor felt were responsible for adverse
reactions on some of his highly sensitive patients.
TRC's earlier indoor/outdoor work for EPA demonstrated that unvented
gas stoves can indeed contribute measurable quantities of CO to the indoor
atmosphere and our sampling methods were able to track the travel of CO from
this source to other parts of the house. However, the scope of this work did
not include the measurement of other pollutants. The objective of the present
EPA sponsored program is to investigate further the indoor generation of air
pollutants in private residences. This effort has been organized into three
major tasks as follows:
Task 1 - Laboratory Investigation
Task 2 - Field Studies
Task 3 - Inventory of Indoor Sources
This report summarizes the entire program. Following this general
introduction, we present the Summary, Conclusions and Recommendations for the
entire program. Then, in sequence, we present reports of each of the three
tasks. Since these tasks represent discrete efforts within the overall program,
we present them essentially as self-contained reports but with cross references
to other tasks where appropriate.

SUMMARY. CONCLUSIONS AND RECOMMENDATIONS
SUMMARY
TRC has completed a 15-month research program on indoor air quality. The
program was carried out in three tasks which are briefly summarized as follows:
1. Task 1 - Laboratory Study
The objective of this task was to measure emmissions of NO, NOo,
and CO from normally used and operated gas stoves and unvented space
heaters in relation to several stove and heater operating variables.
Emissions from the gas appliances as well as emissions as modified by
ventilating hoods were determined in a laboratory study. A brief
survey of stove and heater designs was made to select representative
models for testing. A completely enclosed laboratory structure was
constructed for the evaluation of emissions from the appliance on a
mass basis. Operating variables evaluated included air-fuel ratios,
flame intensity, time and temperature and use of pilot lights.
2. Task 2 - Field Studies
Measurements for N02, NO and CO were made continuously over
2-week periods in 4 homes with gas stoves in the Hartford, Connecticut
area. Separate field measurement programs were carried out during
the spring-summer of 1973 and fall-winter of 1973-1974.
Sampling was carried out by means of a TRC-designed system which
utilized single instruments to obtain data on a 5-minute sequential
basis from four sampling points. Three of the sampling points were
located indoors (one or two locations in the kitchen and either the
living room or bedroom) while one monitored outdoor concentrations.
3
-------
Data on stove use was recorded by the homeowner to permit
comparisons of indoor air quality with stove use.
3. Task 3 - Inventory of Indoor Sources
A two-phase study to identify indoor sources was carried out.
Initially, two of the houses used for the Task 2 effort were used
as a basis for cataloging sources of potential indoor emissions.
We determined that there are many sources of indoor air contamination
which take many forms based on practices within each household.
One of the most widespread source categories within the home
is the dispersal of household products in aerosol form. We
carried out a survey of TRC employees to develop use patterns of
aerosol products and to estimate the effect of such use on
indoor air quality.
CONCLUSIONS
From the results of the work performed, we draw the following conclusions:
1- Combustion products from gas stoves degrade indoor air quality
especially in terms of N02, NO, and CO. In several cases,
levels of indoor N0~ and CO could exceed the air quality standards
for these pollutants if such outdoor standards were to be applied
indoors.
2. Propellant dispersed aerosols also have a significant but widely
variable impact on indoor air quality. While concentrations of
propellants are estimated to be below the Threshold Limit Values
(TLV's) for these materials, special circumstances may cause
these levels to be exceeded on occasion.
- 4 -
-------
3. The half-life of indoor concentrations of CO, an unreactive gas, was
found to be 2.1 hr. NO is also relatively unreactive in the indoor
atmosphere with a half-life of 1.8 hr. N02, on the other hand, showed
a half-life in the same home of 0.6 hr. We conclude that N02 is
lost through reaction, absorption and adsorption.
4. The ratios of N02 to NO produced by gas stoves varied somewhat, but
there was some tendency to produce slightly more NO than NO^.
5. Pilot lights on gas stoves produce a measureable amount of NO, N02,
and CO during inactive stove use periods.
6. Outdoor air quality has a significant effect on indoor air quality,
particularly in the warmer months when the house is relatively
permeable.
7. Highest indoor concentrations of stove-generated pollutants occurred
in the winter when the house was tightly closed.
8. Gas stoves and to a lesser extent unvented space heaters generate
significant quantities of NO, N02> and CO as determined in our
laboratory study. Some difference in emission levels were observed
for older and newer stoves, but these are not directly attributable
to age or design differences. Amounts of pollutants generated are
directly related to the number of burners in operation and the amount
of gas being consumed.
9. Vented stove hoods are moderately effective in removing gaseous
pollutants but recirculating hoods are not effective.
RECOMMENDATIONS
The work performed has shown the need for further work in further defining
indoor air quality, sources of indoor contamination, and the impact of indoor
- 5 -
-------
air quality on occupants of indoor spaces. We believe further work in the
following areas is needed:
1. Further analysis and evaluation is needed of the data developed from
this program. Task 2 of this program generated a large body of
valuable data on the indoor/outdoor patterns of air quality in
several different types of houses with gas stoves. While the data
and their evaluation presented show clearly the magnitude of the
influence of gas stoves on indoor air quality, further analysis of
the data of the type listed below would put these evaluations in
more precise perspective.
a. Extrapolate the data obtained in this program to provide an
estimate of total exposure to NO,-, and CO for the occupants of
houses tested. This would involve the development of typical
occupancy patterns for individuals and patterns of travel,
activity and occupation together with outdoor ambient air
quality data from this program and the State of Connecticut,
and judgments based upon TRC's previous work and literature
sources on what regimes of exposure could be expected for
different occupations and within different types of enclosures.
b. Utilize the existing data to develop preliminary models of the
indoor concentrations in terms of indoor sources (stove use),
design of house, relative permeability of the house, outdoor
concentrations, and meteorological factors (temperature, wind
direction and speed, etc.).
c. Make a detailed analysis of indoor NO,, and CO patterns in
Houses 1, 3 and 4 to corroborate the shorter half life of NO-
as opposed to CO as was determined in the diffusion experiment
at House No. 2.
- 6 -
-------
2. Further definition and quantification of indoor sources is needed.
More detailed inventories together with well designed field measurement
programs should be carried out. Highest priorities should be given to
such common household activities as cleaning, smoking, cooking and use
of aerosol products.
3. Epidemiological studies should be made of the possible effects on the
occupants of homes of the wide range of materials present in the indoor
air. These should be carried out simultaneously with programs to
identify sources, likely contaminants, and field programs to measure
indoor air quality.
4. In the diffusion studies, we determined that NO- from gas stoves
disappears 3 times as fast as NO. Research should be carried out to
determine what happens to N0~. One possible route which has strong
health implications is the formation of nitrate or nitrite aerosol
in the highly humid kitchen atmosphere. A study to establish the
ultimate disposition of N0? in the indoor atmosphere should be
carried out.
5. The indoor/outdoor relationships for nitrate and sulfate aerosol and
their precursors NO and S00 should be developed particularly in view
X 4*
of the formation of N0_ and NO by gas appliances.
6. Air quality standards are based on outdoor concentrations, but
epidemiological data supporting these standards undoubtedly include
the integrated exposure to both indoor and outdoor air pollutants.
Since people spend most of their time indoors, studies should be
designed to establish true human exposure (both indoors and
outdoors) to air pollutants.
7
-------
7. Indoor/outdoor air quality studies need to be carried out on a broader
base. There is a need for studies in different types of structure
located in different types of communities. At the same time there is
a need for carrying out such work in sufficient depth to permit
statistical evaluation of the data, in order to verify the findings
of initial surveys conducted to date.
8. Instrumentation is needed which can reliably operate on a continuous
basis over longer periods of time to permit increased data recovery.

1.0 INTRODUCTION
As part of The Research Corporation of New England's study of sources
of indoor air pollution, Task 1 was planned to investigate emissions
characteristics of gas appliances in a laboratory environment. Task 1 was
developed in response to the lack of information available for pollutant
emissions from gas appliances and their relationship to operating conditions.
TRC evaluated emissions from two gas stoves, an old and a new model,
and an unvented space heater. Emission levels from the gas stoves were measured
for the following types of operation:
1. pilot lights
2. burners
3. oven and broiler
The effects of flame intensity, air-fuel mixture, number of burners in
use, and utensils were determined in this laboratory test program.
The oven and broiler emissions were evaluated under transient and
steady-state operating conditions. In addition to these evaluations, we
determined the effects of recirculating and vented hoods on the characteristics
of pollutant emissions for gas stoves.
We measured nitric oxide (NO), nitrogen dioxide (N0«),and carbon
monoxide (CO) emissions from the gas appliances under the different operating
conditions. These measurements were made with sequential sampling equipment
in an enclosure built to isolate the appliances during the tests. We found
through contact with the local gas utility that the sulfur content of the
odorant in the natural gas was very low, 0.21 yg/kcal. Measurement of SO-
with available monitoring equipment would not have yielded reliable results
and therefore was not performed.
- 10 -
-------
2.0 SUMMARY AND CONCLUSIONS
A brief summary of the results from Task 1 is presented in Table 2-1.
Emission measurempnts are presented for an older and newer gas stove and an
unvented space heater. For comparison, the emissions from a domestic gas
furnace are also included in Table 2-1.
Pilot light NO and NO emissions from the newer stove were less and
CO emissions higher than those from the older stove. The newer stove also has
a pilot light designed to use less gas than the older stove.
Tests designed to evaluate the effect of air-fuel mixture upon burner
operation indicated that the best blue luminous flame was produced at an
intermediate air shutter opening for each stove. Variation in the shutter
opening had little effect on the pollutant emissions for the older stove but
had a greater effect on the newer stove. The intermediate air shutter
opening (best flame) also had the highest oxides of nitrogen levels for the
newer stove.
Evaluation of the number of burners in use and their flame intensity
showed that the emissions are similar for all conditions when adjusted to an
equivalent heat input basis. Oven and broiler emissions are somewhat less
than those for the burners on the same heat input basis. An exception was
the large amount of CO from the oven of the newer stove.
Total pollutant emissions per unit of time from a gas stove are roughly
proportional to the number and type of burners used and the period of use.
The unvented space heater had lower emissions than the stoves with the
exception of NO at high flame and CO at low flame conditions.
Vented stove hoods could capture and exhaust about 40 to 50 percent
of the pollutants generated by the stove depending upon the fan sp^ed used.
Our tests could not detect any removal of gaseous pollutants by a recirculating
hood with a charcoal filter.

From the laboratory study, we conclude that:
1. Gas stoves emit significant quantities of oxides of nitrogen and
carbon monoxides in the following ranges depending upon stove
operation:
NO = 90 - 130 vg/Kcal, 200-1000 mg/Hr
N02 =50-80 vg/Kcal, 100-500 mg/Hr
CO - 400 - 1000 yg/Kcal, 1000-4000 mg/Hr
2. In our tests, pollutant emissions from the newer stove were not
consistently higher or lower than the older stove for the
range of operations evaluated. The oven of the newer stove did
emit about three times more CO than the older stove oven.
3. The different designs of the burners for the two stoves did not
appear to have consistent and reproducible effects upon
pollutant emissions.
4. Pilot lights, although using gas at a small rate, do contribute
quantities of pollutants comparable to those generated during
cooking operations over a typical 24-hour period because of their
continuous nature.
5. Vented stove hoods are moderately effective in removing gaseous
pollutants but recirculating hoods are ineffective in removing
pollutants.
6. An unvented space heater has pollutant emissions in the
following ranges depending upon operation:
NO - 80 - 130 yg/Kcal , 200-800 mg/Hr
N02 = 40-50 vg/Kcal , 100-300 mg/Hr
CO - 300 - 600 vg/Kcal , 1000-2000 mg/Hr
These emissions are less than that for a gas stove, however, total
emissions could be greater if the heater were used continuously.

3.0 DESCRIPTIONS AND PROCEDURES
3.1 Appliance Selection
A preliminary survey was conducted to determine the different types
of stoves, hoods, & space heaters available for residential use. Design
features that could possibly affect pollutant emissions fall into two major
categories, heat input rate and burner construction. Maximum heat input rates for
range top burners are split evenly between 2300 Kcal/hr and 3000 Kcal/Hr. Oven
and broiler heat input rates vary from 3000 Kcal/hr to 6300 Kcal/hr. Burner
construction is divided into four major categories:
1. Steel tube (venturi) with ports or slots
2. Infrared type
3. Cast iron with drilled ports
4. Pressed steel with formed ports
The latter two are predominant with most modern gas stoves having
the pressed steel burners and older stoves the cast iron burners. We chose
one stove from each of these latter two categories for the laboratory study.
Space heaters, not in general use in the Northeast, are available
in several different configurations. They have single or multi-port cast iron
burners and are vented to either the living space or outdoors. The heating
medium is either hot air, steam or hot water. The Project Officer supplied
us with a multi-ported, unvented, hot air space heater for the task.
Range top hoods are available in many different sizes and either
recirculate indoor air or exhaust to the outside. For this study, we selected
a representative hood for each category, one recirculating and one vented.
Table 3-1 summarizes the characteristics of the applicances selected for this
test program.

3.1.1 Newer Gas Stove
This five year old gas stove was purchased used and has four pressed
steel burners. Each burner is rated at 3000 Kcal/hr. There are two pilot
lights for the burners and broiler. The oven, with a capacity of 5500 Kcal/hr,
3
has its own pilot light and has a volume of approximately 98,300CM . It
was chosen as representative of one of the two major types of gas stoves
available and in common use. Air-to-fuel ratios are controlled at each of
the burners by shutters.
3.1.2 Older Gas Stove
This stove is approximately twenty years old and has four cast iron
burners with two pilot lights. Another pilot light is located near the oven
and broiler. The broiler and over are separate compartments of 23,600 CM and
3
65,600CM , respectively. This appliance represents the second major category
of gas stove in use in residential structures. There are two small burners
and two larger ones having individual rated capacities of 2550 and 3000 Kcal/hr,
respectively. The oven has a 3550 Kcal/hr capacity,
3.1.3 Recirculating-Type Range Hood
This hood, which is the most commonly used in modern residences,
has a two-speed fan that draws a maximum of 4.2 cu.m/min. Air from above
the stove passes through a 930 square centimeter aluminum grease filter and
activated charcoal unit. The exhaust from this hood is discharged directly
into the kitchen space.
3.1.4 Vented Range Hood
This second type of hood made by the same manufacturer as the
leclrculating type used in this study has a greater exhaust capacity. The
-------
three-speed fan draws a maxiuua of 8.4 cu.m/min through a 1677 on2 aluminum
grease filter and exhausts this air through a .15 meter diameter sheet
metal duct to the outside.
3.1.5 Space Heater
The space heater which was supplied by the Project Officer, was an
unvented hot air system with a multi-port cast iron burner. This fifteen-year
old space heater has neither a pilot light nor an air-fuel adjustment device.
Combustion air was provided to the 12 finned burners by aspiration. It has
a maximum heat input of 6700 Kcal/hr.
3.2 Procedures
3.2.1 Laboratory Test Enclosure
Figure 3-1 shows the laboratory test enclosure and sampling system
built specifically for this study. The test enclosure was designed and
built to isolate the stoves, hoods and space heater from external influences
and to allow us to monitor the generation of pollutants in a convenient
manner.
The test room enclosed 8.0 cubic meters, 2.4 aeters long and 1.4 meters
wide, and was 2.4 meters high. One door and two sealed windows were installed
to allow access to and observation of the stoves in the test chamber. The sheet
rock walls were covered with a non-adsorbent epoxy base paint and all openings
were sealed with silicone weatherstripping. The air intake for the test
enclosure was a .2 meter- diameter duct. Control of the intake air was
achieved by a variable guillotine damper placed in the inlet duct.
2
Ventilation of the test enclosure was provided with a 8.4 m /Min
fan placed in the .2 meter room outlet duct in the ceiling.

A .15 meter diameter exhaust outlet for the vented hood was placed
in the back wall of the test enclosure. Air flow through the inlet and outlet
was measured by standard type pitot tubes and inclined manometers.
3.2.2 Measurement System
In order to measure pollutant concentrations at multiple locations
and yet conserve the amount of instrumentation and manpower required to
obtain this data, TRC designed and built a unique measurement system as
shown in Figure 3-2. The major components of the system are four continuously
purged sampling lines with an integrating chamber, solenoid valves, Bendix
Chemiluminescent NO/NO Analyzer, Intertech Non-Dispersive Infrared Carbon
X
Monoxide Analyzer, carbon monoxide and NO/NO- Calibration Systems, strip chart
recorders and electronic sequencer. The system design acknowledged the need for:
1. Continuous, uninterrupted operation with only periodic service
2. Frequent automatic and manual calibration checks.
As shown schematically in Figure 3-2, the sample stream from each
of the four locations is piped to a central location through 15 meters of
4.8 mm I.D. Teflon tubing at a rate of approximately 9.5 LPM. This is
equivalent to a retention time of approximately 2 seconds. Each sample
stream is then drawn through an individual 500 ml glass integrating chamber,
through a dlaphram pump and then vented. This arrangement provides continuous
purging of the sampling lines.
From the integrating chamber two small streams are drawn, one to the
Bendix Chemiluminescent NO/NO analyzer and the other to the Intertech
X
NDIR CO analyzer. Solenoid valves (normally closed) on each sample line
are energized by the electronic sequencer at five minute intervals with

each station having its sample being drawn to the detectors once every
twenty minutes. The two solenoid valves that allow samples to be drawn
to the CO analyzer and the NO/NO- detector from the integration chamber are
kept in phase so that the sample stream from each station is being
analyzed simultaneously for CO and NO/NO-. A two pen recorder was used for
the NO and NO. output of the chemiluminescent analyzer and a separate single
pen unit for recording the CO output.
An additional function of the electronic sequencer was to mark the
beginning of each 20-minute sampling cycle. This was accomplished by creating
a vertical slash on each strip chart immediately before the analysis of the
Station 1 sample stream for the three pollutants of interest. This sampling
and measurement system is the same as the one used for the Task 2 field
measurements.
3.2.3 Calibration Procedures
Calibration of the Bendix Chemiluminescent NO/NO- Analyzer was
accomplished with a dynamic dilution module. This module was provided
by the Environmental Protection Agency and is described schematically
in Figure 3-3. A wide range of concentrations of NO and N0« can be
generated by this unit for calibrating the NO/NO- analyzer. Bottled NO
calibration gas with a guaranteed concentration of 95.1 ppm and purified room
air were used to produce the various nitric oxide concentrations. Nitrogen dioxide
can be produced in different concentrations by the use of the ozone generator
that is part of the calibration module.
The procedures used to calibrate the Bendix Chemiluminescent
N0/N0~ Analyzer were provided by the EPA and are identical to those used in
Task 2. A copy of the procedures can be found in Appendix A.

The calibration of the non-dispersive infrared (NDIR) carbon monoxide
3
analyzer was accomplished with zero gas and 13.0 ppm (14,950 yg/m ) CO calibration
gas. Zero gas was introduced into the detector cell to establish the zero
baseline of the device. Calibration gas was then used to determine the span,
or chart displacement, of a known concentration of carbon monoxide. Finally,
the zero gas was re-introduced to ensure the baseline stability.
3.2.4 Sampling Locations
To determine the generation and behavior of the pollutants from the
gas appliances with and without the hoods in operation, we chose the four
sampling locations within the test structure as follows:
Station 1: Test enclosure air inlet
Station 2: Above the gas appliance - approximately 1.7 meters
above the floor
Station 3: Test enclosure air outlet directly downstream of the
sealed fan unit.
Station 4: Recirculating hood outlet or in outlet duct from vented
hood.
Station 1 pollutant measurements were used to establish the baseline,
or background, levels in the air entering the test structure during the
experiments. Initial comparisons of measured inlet and outlet air volumes
showed the presence of sufficient leakage, 10% to 50%, to disallow the conversion
of the inlet concentrations to a mass basis. The concentration of the air
entering the structure through all openings was assumed to have a pollutant
concentration as measured in the inlet duct.
Station 2 was placed in the breathing zone directly above the stove.
This location was chosen to provide data that would be representative of
- 23 -
-------
concentrations encountered by the person using the gas appliance and to
monitor the presence of steady-state concentrations within the enclosure.
Room outlet pollutant concentrations were measured at Station 3
in the test enclosure outlet duct. Air flow measurements taken at Station 3
were used with the Station 1 inlet pollutant concentrations to determine the
mass input rate of pollutants into the test structure. The pollutant
concentrations at this outlet were converted to a mass basis by the use of
these air flow data as well.
Station 4, depending upon the individual test, was placed in either
the recirculating hood outlet or in the outlet duct from the vented hood.
When neither hood was in use, this station remained inoperative.
Test personnel monitored pollutant concentrations at all four locations
throughout each test sequence. Our reported results were taken from
reproducible, steady-state conditions except when transient conditions were
under study. The steady-state condition was achieved when pollutant levels
at Station 2, above the gas appliance, stopped fluctuating. In most cases,
duplicate tests were run to verify the initial tests.
3.3 Test Plan
A comprehensive test plan was prepared to guide the measurement
personnel in performing the laboratory tests in rapid sequence. The plan
was designed to assess the emission quantities produced by gas stoves, space
heaters and the pollutant removal capability of vented and unvented hoods.
The tests designed for these objectives are discussed in the next three
sections.
- 24 -
-------
3.3.1 Gas^ Stoves
The generation and behavior of pollutants from gas stoves is a
function of many inter-related variables including burner and oven size
and design, pilot lights, air-fuel mixture, flame intensity, etc.. To have
a test plan of manageable size to give us meaningful results we divided
these effects into the following categories:
1. pilot lights
2. air-fuel mixtures
3. burner size
4. flame intensity
5. combinations of burner use
6. broiler
7. oven
8. utensils
Each of these variables was individually isolated for testing with
each of the two stoves and determined in the sequence listed above.
Pilot Lights- With most modern stoves having continuous rather than
manual pilot lights, we decided that this aspect of the stove's impact on indoor
air quality deserved investigation. It was relatively easy to seal each stove
in the test enclosure and monitor the pollutant emissions of the pilot lights.
Burner Air-Fuel Mixture- The first series of tests on each stove was
designed to give comparative data for each stove showing the effects of different
air-fuel mixtures on pollutant emissions. On the older stove with two sizes of
burners, we tested the larger one which was comparable to those on the newer stove.
A high flame intensity was used for these tests on one burner on each stove.
- 25 -
-------
Changes in the air-fuel mixture were made by adjusting the primary
air-shutter under each burner. Three air-shutter adjustments were tested:
maximum primary air, intermediate and minimum primary air. The intermediate
air-shutter setting was judged as the position which created the best
luminous blue flame, considered a; * nost efficient operating condition.
This setting was used for all the subsequent tests.
Burner Size- Since the newer stove had four equal size burners, this test
series was run on the older stove with 2 small and 2 large burners. Separate
tests were run with each size burner set at a high flame intensity. The data
were used to evaluate what effects of pollutant emissions could be attributed
to the different size burners.
Burner Flame Intensity- Two extremes of flame intensity, high and low,
were chosen for this test series on the newer stove. Each flame intensity was
tested separately to compare the effects of these two operating conditions on
pollutant generation.
Combination of Burner Use- This test series was designed to determine
the buildup of pollutant emissions with the successive ignition of each burner
at 15 minute intervals. Each stove was tested at low flame and at high flame
intensity. The newer stove had one burner with a temperature sensor that
shuts off the flame when the preset temperature is reached. This burner was
the last one ignited in the test sequence so that any possible disturbance in
pollutant emissions by the modulating flame could be avoided.
Broiler- The broiler in each stove was tested under two different
operating conditions, transient and steady-state. We monitored the pollutant
emissions during the transient phase as the broiler heated up to its thermostat
setting, 500°F. When the broiler reached this temperature, the steady-state
tests were run. These two operating conditions were re-tested with one burner
in operation at a high flame.
- 26 -
-------
Oven Our spring-summer phase of the Task 2 field measurements showed
the oven and broiler as significant sources of NO , NO and CO. As far as we
could tell, these emissions were greatest during the oven warm-up period.
To investigate these findings in a laboratory situation we tested each
stove under two conditions, transient and steady-state. The transient condi-
tion was represented by the oven's warming up to the thermostat setting, 475°F(245°C)
The steady-state tests were run after the oven reached and maintained the
preset temperature. This series of tests at the two operation conditions was
repeated with the addition of one burner set on high flame.
Utensils- We chose several representative types of utensils for
testing on one burner of each stove. Pollutant concentrations were determined
separately for aluminum, cast iron, stainless steel, and Pyrex utensils. The
flame settings, low and high, remained unchanged until the effect of each uten-
sil had been measured. Another test for comparative purposes was run at the
same flame setting with no utensil on the burner. This test with no utensil
was used as a baseline to compare the relative effects of each utensil. Water was
placed in each utensil and brought to a boil during each test.
3.3.2 Hoods
A comparison of the unvented and vented hoods was made from tests with
a combination of burners and the oven in use on the newer stove. These
tests were run to determine the respective pollutant removal efficiencies,
if any, for each hood. Tests were also run with the fan on the vented
hood operating at two different speeds to determine the effect of exhaust
rate on removal efficiencies.
3.3.3 Space Heater
The unvented space heater is a fairly uncomplicated appliance and in
contrast to the gas stoves there are few operating conditions that could be
- 27 -
-------
investigated. Our tests were conducted under two operating conditions,
transient and steady-state for a low and high heat input. Pollutant
emission levels were measured for each of these four conditions.
3.4 Calculations
The pollutant emissions from the gas appliances were determined from
comparisons of the data collected at each of the four sampling locations
within the test enclosure. The contribution of the gas appliance was
calculated as the difference between the mass emissions at the outlet,
Station 3, and the mass rate of pollutants entering the test enclosure. The
concentration of pollutants in the room inlet air was measured at Station 1
and the mass inlet rate was then calculated with air flow data from Station 3.
Using the Station 3 air flow data took into account any leakage that would
not be detected at the Station 1 room inlet.
For the tests with the vented hood in operation, the total air flow
and pollutant concentration were determined as the sum of the emissions
through the room outlet duct, Station 4 and the hood outlet duct, Station 3.
From this sum, the pollutant mass rate entering the test enclosure was sub-
tracted to obtain the mass emission rate of the gas stove.
Pollutant emission levels from the stove on a heat input basis were
calculated from the mass emission rates and gas usage data taken from an
integrating meter installed in the natural gas supply line.
The effect of various utensils was determined by a simple measurement
scheme utilizing the concentration of pollutants measured directly over the
stove adjusted for any change in the incoming room air pollutant concentrations.
Concentration measurements were judged more sensitive for measurement of small
differences which may not have to be uncovered using the above mass emission
calculation procedure.
- 28 -
-------
4.0 RESULTS AND DISCUSSION
The pollutant emission levels for the gas appliances were calculated
from the concentrations measured at Stations 1 and 3, the room inlet and outlet,
respectively. The difference between the inlet and outlet mass rates of
pollutant are attributable to the effect of the stove.
The emission results shown in Tables 4-1 to 4-6, with the exception
of Table 4-3, are presented on a heat input basis, micrograms per kilocalorie,
yg/Kcal and also on a per unit time basis, mg/Hr. Results on both bases are
shown to provide an emission factor independent of the amount of fuel used
and an emission rate for a particular set of conditions. Table 4-3 shows
the pollutant concentrations above the stove as a measure of the effect of
utensils on pollutant generation.
4.1 Gas Stoves
The gas stove provided the greatest variety of operating situations
that could affect the generation of pollutants. The effects of pilot lights,
burners, oven, broiler and utensils were evaluated. For the burners, additional
characteristics including air-fuel mixture, size, flame intensity, and number
in use were evaluated for their effect on pollutant emissions.
4.1.1 Pilot Lights
The results for the pilot light tests on the two stoves are presented
in Table 4-1. Some significant differences in pilot light pollutant emissions
levels are apparent in these data. Both of these appliances have three pilot
lights yet gas consumption for those in the older stove was 50% higher than
for the newer stove. Carbon monoxide emissions for the newer stove were
approximately twice as high as from the older one. Oxides of nitrogen emissions
were substantially lower from the pilot lights of the newer stove.
The pilot lights on newer gas stoves are designed to consume less gas
than those on older stoves. This design change is confirmed by our natural gas
input measurements taken during the pilot light tests.

Ambient background NO, NO , and CO levels in the test enclosure of 26,
50, and 2490pg/m , respectively, were comparable to those encountered in the
field sampling program during inactive periods, such as late night and early
morning. It is during this time period that measured pollutant levels reflect
only the pilot light emissions. The difference in pollutant emissions from the
pilot lights is undoubtedly due to a combination of factors including stove age,
condition, and design.
4.1.2 Burner Primary Air-to-Fuel Mixture Effects
One of the most fundamental factors of burner operation that can be
modified is the air-fuel mixture. Changing the air-fuel mixture by adjusting
the air shutter under the burner would expectedly alter the combustion charact-
eristics and subsequently affect pollutant generation. One burner on each stove
was used for this test series. The burner was set at high flame and its air
shutter was adjusted to three positions; full open, full closed, and intermediate.
The intermediate air shutter setting was judged as the position which created the
best luminous blue flame, considered as the most efficient operating condition.
At the intermediate air shutter setting the emission levels from the
newer stove were noticeably higher than those from the older unit as shown
in Table 4-1. Increasing the primary air to a maximum for the newer stove caused
a 33% and 42% reduction in NO and CO levels while NO levels increased by 67%.
Reducing the primary air in the burner of the older stove caused a slight decrease
in the pollutant emissions. The minimum air setting on the newer stove affected
NO emissions only slightly while the CO decreased and the N0? increased as
compared to the intermediate shutter setting values.
Generally, these data show that the emissions from the older stove
are less sensitive and more uniformly independent of the air-fuel mixture.
- 31 -
-------
Emissions from the newer stove are noticeably higher at the optimum air shutter
setting.
4.1.3 Burner Size Effects
Since the newer stove had four burners of equal size, we ran these
tests on the older stove only. The .^.^11 and large burners were tested separately
at high flame intensity. The pollutant emissions data presented in Table 4-1
show the burner size has little effect when compared on a heat input basis.
4.1.4 Burner Flame Intensity Effects
TRC investigated pollutant emissions at two flame intensities, high
and low, on one burner of the newer stove. The high flame had a heat input
more than twice that used for the lower flame. As shown in the results presented
in Table 4-1, emission factors for NO, N02> and CO during these two different
conditions of burner operation are closely correspondent. The greatest
difference in emissions is apparent for the carbon monoxide with the high
flame having a 50% higher CO emission factor than the low flame. Total emission
rates per unit time increase in proportion to the amount of fuel used.
4.1.5 Burner Ignition Sequence Effects
For this series of tests, each burner was ignited successively at
15-minute intervals. The build up of pollutant emission levels was monitored
for a 60-minute period, until 15 minutes after the fourth burner was ignited.
At each flame intensity, nitric oxide and N02 emission factors
were
relatively constant with a few exceptions for each stove, regardless of the
number of burners in use, when adjusted to a heat input basis.
Carbon monoxide emission factors seem to be affected the most by
increased number of burners in use. The burners of the older stove generated
more N02 and CO per unit of heat input than those of the newer one, especially
during the low flame tests. In these low flame tests, nitric oxide emission
- 32 -
-------
factors for the newer stove burners were noticeably higher than those from
the older stove. These differences are less apparent for the high flame
tests.
Pollutant emission quantities per unit time were less for the older stove
than the newer stove except for carbon monoxide, particularly when a low flame
was used. The difference in emission quantities between stoves was due to the
smaller fuel consumption rate of the older stove at a specified setting. In
spite of this smaller fuel consumption rate, the carbon monoxide emissions for
the older stove were greater than the newer stove.
4.1.6 Broiler and Oven
For the tests on each stove's broiler and oven, we chose two operating
conditions for investigation defined as transient and steady-state. The
transient condition included the period from oven or broiler ignition until
the temperature reached 475°F (245°C) for the oven and 500°F (260°C) for the
broiler. For the steady-state mode, we then operated the oven and broiler at
the above settings for a similar time period during which the oven or broiler
flame would cycle on and off to maintain the desired temperature. The thermostat
for the older stove did not work properly and consequently, the flame remained on
even after the desired temperature was reached.
The results for this test series are shown in Table 4-2. For both
stoves, pollutants are generated at a generally higher rate per amount of heat
input while operating in the transient condition as compared to steady-state.
The broilers of both stoves have comparable emission levels except the NO
from the newer broiler is 50% higher than the older one during a steady-state
operation. The newer oven generates more carbon monoxide but less oxides of
nitrogen than the older oven at steady* state.

Comparing the oven and broiler emissions with the burner emissions in
Table 4-1 shows that based upon equivalent heat input, the oven and broiler
generally produce less oxides of nitrogen and more carbon monoxide than the
burners. However, the quantity of pollutants per unit time is greater for
the oven and broiler than the burners because of the greater fuel consumption
of the former during normal operation.
4.1.7 Utensil Effects
Table 4-3 shows the results of our pollutant concentration measurements
with different utensils on one burner of the new stove under two flame inten-
sities, high and low. The cast iron and the stainless steel utensils show the
ability to reduce NO- to NO in the low flame test condition, although the relative
change is not significant. The most substantial utensil effect apparent is the
much higher CO concentrations for the aluminum pot test. Each utensil shows the
effect of decreasing NO- concentrations when compared to the test done without
utensils.
Behavior of each utensil in affecting pollutant concentrations during
the high flame tests was different from the low flame tests. Nitric oxide and
NO. concentrations were generally higher with a utensil on the burner than without
one. Except for the stainless steel utensil, carbon monoxide levels were lower
with the use of each utensil.
The magnitude of the observed effects of utensils upon pollutant concen-
trations , although measurable, does not appear substantial. No one utensil has
a substantial effect upon pollutant measurements.
4.2 Hoods
Table 4-4 shows the results of our tests on the vented hood's efficiency
in removing pollutants from the test enclosure. These data ghow that the vented
hood is moderately effective in removing pollutants from the room. The higher

fan speed, with its greater induced draft above the stove, will capture and
exhaust about 50% of the pollutants generated by the stove. With the fan shut
off , there is enough draft to allow measurable amounts of pollutants to ebcape
through the hood outlet duct.
Table 4-5 presents the result ~r tests to determine the ability of
the charcoal filter in the recirculating hood to remove gaseous pollutants.
Two separate tests were run, one with the ducted hood without a filter and one
with the recirculating hood with the charcoal filters. In both cases, the newer
stove was used. Comparison of the data from both tests shows in our judgment
no collection efficiency for the charcoal. While these is a difference of
about 10% in the NO and CO measurements between tests, we estimate this to be
measurement error. From comparison of other data taken during the test program,
the mass balance approach we have used to determine emissions has an accuracy
of +10% which is reasonable for the objectives of this task. A more precise
evaluation of a charcoal filter would have to be determined by a different
laboratory method which was beyond tha scope of this task.
4.3 Unvented Space Heater
Table 4-6 shows the results of our tests on the unvented space
heater. The uncomplicated nature of this appliance left us with relatively
fextf operating conditions to evaluate. We chose two operating conditions,
transient and steady-state for the emission measurement tests.
Our measurements show that the pollutant emissions are relatively higher
during steady-state operation of the space heater at the preset temperature.
This is opposite to our findings for the gas stove oven and broiler tests.

We also see that the high flame operating condition as having greater emissions
than the low flame condition. In general, our tests show pollutant emissions
as somewhat lower than those from the gas stoves when adjusted to a heat
input basis. However, using the space heater continuously would add a consider-
able amount of pollutants to the indoor atmosphere when compared to the inter-
mittent operation of gas stoves.

TASK 2
FIELD STUDIES
- 42 -

1.0 INTRODUCTION
The purpose of this task is to determine the impact of gas stove emis-
sions and outdoor air quality on indoor air quality. The work performed in this
task consisted of a field measurement program at four private homes with gas
stoves in the Hartford, Connecticut area. The homes selected represented a
spectrum of conditions related to:
Home age, size, and configuration
Stove age and condition
Stove use
Home location in relation to outdoor sources.
The field sampling program was divided into two sampling periods, spring-
summer and fall-winter and carried out at three separate homes during each period.
Because of sparsity of stove use at one of the houses sampled in the
spring-summer sampling period, another house was selected and used as a replace-
ment for this house during the fall-winter sampling period. Thus, in all, four
different houses were investigated during this task. Nitric oxide (NO), nitrogen
dioxide (N0_), and carbon monoxide (CO) were monitored continuously at three loca-
tions within and at one location outside each house for about two weeks in each
sampling period.
The data were compiled as 2-hour and daily averages. Stove use data
recorded by the residents provided the basis for our evaluation of the impact
of gas stoves on indoor air quality.

2.0 SUMMARY AND CONCLUSIONS
2.1 Summary
During the spring and early summer of 1973,, and again in the following
fall and winter, TRC conducted a measurement program in three private residences
to determine the effect of internal generation of pollutants from gas appliances
upon indoor air quality. A modern suburban home, an older urban home, and a
suburban two-story apartment each with a gas stove were selected for the program.
After the spring-summer sampling period, we decided to replace the older urban
home because of little stove use. Thus, for the fall-winter period, a replace-
ment home was selected. It was a 14-year old suburban, single-family home in a
development of similar homes.
Approximately two weeks of monitoring for nitrogen dioxide (N0_), nitric
oxide (NO) and carbon monoxide (CO) were conducted at each structure. Three
sampling sites inside each structure and one outside were used as data collec-
tion points.
In order to sample at all four locations simultaneously and yet conserve
equipment and manpower, TRC designed and built a measurement system that enabled
the use of a single analyzer for NO- and NO and a second analyzer for CO. An
electronic timer, solenoid valves and continuously purged sampling lines were
used to permit the analysis of sample streams from each location in rapid sequence.
During the spring-summer sampling period the four sampling locations
for each house were: kitchen (over the stove, except as noted below), living
room, bedroom and outside. At the request of the Project Officer, sampling
during the fall-winter period was modified somewhat. A second sampling
position was located in the kitchen but displaced somewhat from the stove.
The purpose of this sampling point was to provide data which would be more
representative of the generalized kitchen atmopshere than the sampling point
- 44 -
-------
immediately adjacent to the stove. The third sampling point was placed in
the living room during the first week and in the bedroom during the second
week of the 2-week sampling period.
At House No. 1, during the spring-summer sampling period, we initially
encountered a number of off-scale readings and subsequently moved the kitchen
sampling location about 1 meter from the stove, over the sink for the rest of
this period.
All monitoring equipment was placed inside the structure sampled and
serviced usually every other day by a TRC staff member.
All field data were recorded on strip charts which were examined and
verified before reduction to five-minute average values using a semi-automatic
chart reading instrument. The five-minute data were then keypunched and
entered into TRC's computer to facilitate data analysis.
A summary of the data for this task is presented in Table 2-1. The
data show that there are significant differences in the indoor patterns of
pollutants within each of the houses which are undoubtedly a function of house
design, stove use patterns, outdoor concentrations and other factors. How-
ever, two points are clear: (1) Except for CO in House No. 2, the concen-
trations of the pollutants measured are higher inside than outside and (2)
kitchen concentrations are always higher than those in other parts of the
house.
Indoor concentrations of NCL in the kitchen at most of the houses are
at levels which would exceed the annual average air quality standard of
3
100 yg/m if projected over one year. In several instances, a concentration
3
of 100 yg/m is approached or exceeded throughout the house. Indoor CO
concentrations during the winter at House No. 3 and No. 4 approached the 8-hour
3
average air quality standard of 10,000 yg/m .

Using a study of brief records from the continuous analyzers together
with stove use data showed clearly the response of indoor air quality throughout
the house to stove use. A statistical analysis of the 5-minute air quality data
showed the frequency of occurrence of various values for each sampling location.
In most cases, the relative positions of the cummulative frequency distribution
curves could be explained in terms of season, stove operation, and the behavior
of the pollutant in question.
A diffusion experiment conducted at House No.2 showed the decay patterns
of NO , NO and CO. NO was found to decay much more rapidly than the other
pollutants, and several possible theories were postulated.
The study showed that the impact of continuously burning pilot lights on
several of the stoves contributed air contaminants to the indoor atmosphere.
2.2 Conclusions
Based upon the findings of this task effort we draw the following conclu-
sions :
1. Stove use and outdoor air quality both influence indoor air quality.
This joint influence is a function of house permeability as deter-
mined by season. No evidence could be found that stove and house
aSe Per se influenced indoor air quality.
2. The patterns of indoor air quality are influenced by interior design
features.
3. The half life of CO, an extremely unreactive gas, was found to be
2.1 hours in House No.2 during an unoccupied period. The half life
for NO was 1.8 hours indicating its relatively high stability in the
indoor atmosphere. On the other hand, NO had a half life of 0.6 hours
- 47 -
-------
indicating that in addition to dispersion and dilution, NCL
disappears through reaction, absorption, and/or adsorption.
Ihis effect was noted in a qualitative way in several of the other
houses, especially House No. 4 in the winter.
4. Stove pilot lights were ^ocuid to be a significant source of
N0«, especially at House No. 3.
5. If one can assume that an outdoor air quality standard can be
applied indoors, the data show that the air quality standard
for CO (8-hour average) can be exceeded.
6. Average kitchen N0_ concentrations for most sampling periods
were two to four times the outdoor NO- concentrations.

3.0 PROCEDURES
3.1 Structure Selection
The field measurement program was designed specifically to evaluate the
effect of gas cooking appliances on indoor pollutant levels. While gas
stoves are certainly not the only source of indoor pollutants, they are a
readily identifiable source about which little is known. The major
pollutants of interest that are emitted from gas appliances are nitrogen
dioxide (NO..), nitric oxide (NO), and carbon monoxide (CO). Four structures,
a modern suburban house, a suburban 2-story apartment, an older, urban
single-family house and a medium size and age, suburban, single-family house
were selected for the measurement program. Table 3-1 lists the characteristics
of the four structures.
These residences represent the wide differences in land use, house type
and layout, gas applicance age and life styles which are desirable in an
exploratory study such as this.
We chose House No. 1 as representative of a large, modern split-level
2
house with approximately 2000 ft of floor area. Figure 3-1 is a schematic diagram
of this house and Figure 3-2 is a photograph of the house. House No. 1 is in a
residential development of similar homes in Rocky Hill, Connecticut, and is
located about 2400 feet west of Interstate 91 which is a major north-south highway
that follows the Connecticut River Valley. This eight-year old house consists of four
half-levels each spaced approximately 3 or 4 steps above the other in a split-level
arrangement. The kitchen is large and open and directly connected to the dining,
living and family rooms. The stove, which is the same age as the house, is located
on an exterior wall near a window and has a recirculating type exhaust hood above
the surface burners. A family of four occupies the house. The children are
teenagers and the housewife does not have an outside job.

House No. 2, shown as a schematic in Figure 3-3 is an older home with an
equally old stove. This house, a photograph of which is shown in Figure 3-4, is
2
a seven-room, 2-story single family dwelling of about 1500 ft of floor area.
The neighborhood is an area of similar aged houses located in the south-end of
Hartford. Campfield Avenue, an artery for local traffic in that area, runs in
front of the house. Living areas of the house are located on the first floor
and bedrooms upstairs. The stove is located next to an interior wall and there
is no exhaust hood. The oven exhaust is vented to the outside. The only
occupant is a young bachelor. This house was not used for the fall sampling
period because of the sparse stove use during the spring-summer period.
The third dwelling used for the Task 2 field measurement program, is
shown schematically in Figure 3-5. House No. 3 is a two-floor, 4-room apartment
with the kitchen and living area on the first floor and 2 bedrooms on the second
floor. A photograph of this home is shown as Figure 3-6. This dwelling is part
of a garden apartment complex in the town of Newington, Connecticut. This complex
is located approximately 500 feet north and west of local main roads. Although
the area surrounding the complex is commercial and residential, large tracts
of undeveloped land lie to the north and to the west of this apartment.
On the first floor there are no openings to the outside except the
front door and a glass sliding door at the opposite end of the living area.
Typical of many modern apartments, the kitchen is only a small
workspace with no windows or other outside ventilation. There is a recirculating
type hood over the stove. The housewife and two small children are normally
home during the day.
The fourth dwelling used for the Task 2 field measurement program,
House No. 4, replaced House No. 2 for the fall sampling period. A plan

layout of this house is presented in Figure 3-7. This house is a single floor
ranch-style home enclosing approximately 1500 square feet. A photograph of
this home is shown as Figure 3-8. Located in Enfield, Connecticut, this house
is part of a large development of similar dwellings built in 1959. It is located
approximately 1000 feet from a local main thoroughfare, Elm Street. The area
surrounding this house is zoned residential and commercial. Several large
shopping centers lie to the south of this house, on the opposite side of Elm
Street.
The kitchen in this house opens directly into the dining area and
living room and the stove is not vented to the outside. The occupants of this
dwelling are two adults, one teenager and one young adult.
3.2 Measurement System
The objective of the field measurement program dictated that pollutant
concentrations be determined at several points within the structure being
sampled. A simultaneous measurement of the ambient outdoor concentration of
each pollutant measured is also desirable to act «s a reference and to gauge
the possible influence of outdoor concentration on the levels measured
indoors. Locating individual monitors at each sampling point would represent
a substantial equipment investment and would result in multiple servicing and
space requirements,not to mention data reduction problems, and lack of
confidence in the comparability of data from point to point.
In order to measure pollutant concentrations at multiple locations and
yet conserve the amount of instrumentation and manpower required to obtain
this data, TRC designed and built a unique measurement system as shown in
Figure 3-9. Four sampling locations as described in Section 3.4 were chosen

for sampling, three indoors and one oiitside. The major components of the
system are four continuously purged sampling lines with an integrating chamber,
solenoid valves, Bendix chemiluminescent NO/NO analyzer, Intertech Non-
Dispersive Infrared Carbon Monoxide Analyzer, carbon monoxide and NO/NO
Calibration Systems, strip chart recorders and electronic sequencer. The
system design acknowledged the need for:
(1) Continuous, uninterrupted operation with only periodic service
(2) Frequent automatic and manual calibration checks
(3) Ability to be readily moved from one location to another
(4) Small space requirement within the sampled structure.
As shown schematically in Figure 3-9 the sample stream from each
of the four locations is piped to a central location through 15 meters of
4.8 millimeter I.D. Teflon tubing at a rate of approximately 9.5 LPM. This
Ls equivalent to a retention time of approximately 2 seconds. Each sample
stream is then drawn through an individual 500 ml glass integrating chamber,
through a diaphram pump and then vented. This arrangement provides continu-
ous purging of the sampling lines.
From the integrating chamber two small streams are drawn, one to
the Bendix Chemiluminescent NO/NO analyzer and the other to the Intertech
NDIR CO analyzer. Solenoid valves (normally closed) on each sample line are
energized by the electronic sequencer at five-minute intervals with each
station having its sample being drawn to the detectors once every twenty
minutes. The two solenoid valves that allow samples to be drawn to the CO
analyzer and the NO/NO detector from the integration chamber are kept in
phase so that the sample stream from each station is being analyzed simultaneously
for CO and N0/N0~. A two-pen recorder was used for the NO and NO output of
the chemiluminescent analyzer and a separate single pen unit for recording the
CO output.
- 62 -
-------
An additional function of the electronic sequencer was to mark the
beginning of each 20-minute sampling cycle. This was accomplished by creating
a vertical slash on each strip chart immediately before the analysis of the
Station 1 sample stream for the three pollutants of interest. A sample of
an NO/NO trace is shown in Figure 3-10.
£~
3.3 Calibration Procedures
Calibration of the Bendix Chemiluminescent NO/NCL analyzer was
accomplished with a dynamic dilution module. This module was provided by
the Environmental Protection Agency and is described schematically in
Figure 3-11. A wide range of concentrations of NO and N02 can be generated
by this unit for calibrating the NO/NO analyzer. Bottled NO calibration gas
with a guaranteed and EPA verified concentration of 95.1 ppm and purified room
air are used to produce the various nitric oxide concentrations. Nitrogen
dioxide can be produced in different concentrations by the use of the ozone
generator that is part of the dilution module.
The procedures used to calibrate the Bendix Chemiluminescent NO/
NO- Analyzer were provided by the EPA. A copy of the procedures can be
found in Appendix A.
The calibration of the non-dispersive infrared (NDIR) carbon monoxide
analyzer was accomplished with zero gas and 13.0 ppm CO calibration gas.
Zero gas was introduced into the detector cell to establish the zero baseline
of the device. Calibration gas was then used to determine the span, or chart
displacement, of the known concentration of carbon monoxide. Finally, the
zero gas was re-introduced to ensure the baseline stability. The electronic
sequencer automatically charged zero gas to the NDIR CO analyzer once every
twenty-four hours as another check for baseline stability between manual
calibrations.

3.4 Field Operations
The sampling equipment and auxiliary calibration devices were installed
in an unobtrusive location in each house that would not result in interference
with the residents' activities. Teflon sample lines were run from the
equipment to four sampling locations:
Designation Spring-Summer Fall-Winter
Station #1 Kitchen-Over Stove Kitchen-Over Stove
(except Home No.l)
Station #1A Kitchen-Approx. 1 meter from Stove
Station #2 Living Room Living Room
Station #3 Bedroom Bedroom
Station #4 Outside of Structure Outside of Structure
The sample intake for each station was placed in the breathing zone,
between 1.4 and 1.8 meters above the floor. The sample intake for Station #1,
in the kithcen, was placed directly over the stove except at House No. 1 during
the spring-summer sampling period. For this sampling period at House No. 1,
the sample intake was placed approximately 1 meter from the stove. This
location corresponds to Station 1A for the fall-winter sampling period when
it was possible to locate Station 1 directly above the stove. The data from
Station 1 was used to determine the concentrations of N0_, NO and CO at the
source, the stove. Comparison of these data with those obtained from the other
stations shows the behavior of the pollutants as they diffuse through the
structure and the effect of the source on the indoor air quality within the
structure.
Station 1A (placed approximately 1 meter from the stove) was used in the fall-
winter sampling period to determine N0?, NO and CO concentrations within the
- 66 -
-------
kitchen, other than directly above the stove. These data were intended to show
the behavior of the pollutants in the vicinity of the stove as they diffuse
from the source throughout the structure.
Station 2 was placed in the living room away from windows, doors and
air conditioners. Station 2 was used (alternately with Station 3) for
about half of the fall-winter sampling period at each house. Comparison of the
»
data obtained from Stations 1, 1A and 2 was intended to show the characteristic
changes in indoor air quality in an area on the same level as the source,
at Station 1.
Station 3 was placed in an upper level bedroom to provide data to
determine the relationship between concentrations in the kitchen and more
remote areas within the structure, particularly where people spend 8 hours
sleeping. As noted earlier, this sampling location was alternated with
Station 2 during the fall-winter sampling period at each house with the
exception of House No. 4. At this house, it was not possible to sample at
Station 3 because of the inconvenience it would have caused the residents.
Station 4 was placed outside the structure to provide reference
measurements for the pollutants measured indoors. Measurement of the outdoor
pollutant concentrations was necessary to determine if they control the indoor
concentration by infiltration. The net contribution of the stove to indoor
air quality was determined by comparing the outdoor with the indoor concentrations.
After installation of the equipment and deployment of the sampling
lines, TRC personnel verified their correct function in the operating mode.
Calibration procedures as mentioned in Section 3.3 were used after a warm-up
period of several hours and sampling of the four stations was started.
- 67 -
-------
A form was developed for use by the housewife or other person using
the kitchen to record pertinent data on stove use. The total number of ninutes
of oven and burner use were tabulated for each day of sampling. These forms
provided a record of the level of use and the respective time of use of the
stove that was useful for interpretation of the sampling data. A copy of
this form is shown as Figure 3-12.
TRC personnel serviced the equipment at least every other day. The
service included calibration and functional checks of the sampling equipment.
Adjustments were made as necessary. The residents assisted by frequently
recording time and events directly on the strip charts and alerting TRC to
any possible malfunction that occurred.
In general, the instrumentation in the measurement system performed
well and dependably for the duration of both portions of Task 2, except
for several problems at House No. 3. The Bendix Chemiluminescent NO/NO
x
Analyzer held its calibration and baseline very well and in retrospect we
probably could have reduced the frequency of calibration checks.
Substantial data were lost at House No. 3 during the spring-summer
sampling period by a. combination of sticking solenoid valves for Stations
1 and 2.
Shortly after this problem was rectified, a solenoid valve in the
Bendix Chemiluminescent NO/NO Analyzer malfunctioned, thus preventing
X
separate determinations for NO and NO . We replaced this instrument with a
back-up one and the amount of lost data was minimized.

Zero drift in the CO detector was a recurring problem during the
spring-summer sampling period. In most cases, we were able to interpret the
data adequately but in a few cases the baseline drift was so extreme that some
data were lost. TRC personnel performed an extensive overhaul of the CO
analyzer prior to the outset of the f " "* -"'nter sampling period and the CO
zero drift problem was solved.
The schedule of monitoring periods was as shown below:
Spring-Summer Fall-Winter

3.5 Data Summarization
The considerable amount of data accumulated from the field effort in
Task 2 precluded manual examination of the data in its entirety. Semi-automatic
analog to digital conversion equipment and computer programs were used to reduce
the labor in the data evaluation process.
Each strip chart was examined and valid data periods were identified for
further reduction. Those sections of the charts that showed questionable data were
eliminated from evaluation. The data from the NO/NO charts were converted to
digital form and thence to punch cards using a Gerber analog-to-digital converter.
The data from the CO charts were hand reduced, then transferred to coding forms
for subsequent keypunching. Random samples of the punch cards were cross-checked
with the original charts. Care was taken to insure that the data matched and
- 70 -

keypunch errors were eliminated. Initial computer printouts included both
concentration values and net chart division displacement to facilitate further
checking of the results. The results were then put on punch cards or magnetic
tape for additional analysis.
To develop diurnal trends in air quality at the three indoor and one
outdoor sampling locations, we accumulated five-minute bits into two-hour
averages. Occasionally, less than 6 (the maximum possible number) five-minute
bits of data were available for each two-hour period since some data were lost
during instrument servicing periods and during periods of instrument malfunctions.
In a few isolated cases, there were as few as one or two five-minute bits for
a given two-hour period. Nevertheless, we defined the two-hour average as the
average of all five-minute bits in that period even though less than 6 bits
might be available The data in Appendix B show the two-hour averages for each
location and the number of five-minute bits used for calculation of the averages.
In calculating the daily averages, we gave equal weight to all two-hour
averages even though some were based on less than 6 bits of data. However, a
daily average was not computed for any day which had one or more two-hour
average values missing for all four stations. Note in Appendix B that daily
averages are shown only for those days in which a full compliment of two-hour
averages were available.
In addition to the above summaries, we developed a number of summaries
of the diurnal pattern of N0? for several of the house-pollutant-season
combinations in terms of a "composite day". Here we determined the average
concentration for each two-hour time interval for all those days for which 12
valid two-hour average values were available.
- 71 -
-------
Frequency distributions for NO, NO- and CO data were compiled from all
the five-minute data at each location for each house in order to assess the
frequency of exposure to the range of concentrations measured during the field
program. In constructing these distribution curves, we used all five-minute
data and assumed that any loss of da 1 -"ing a sampling period was more or
less randomly distributed by time of day. While these frequency distributions
may not be statistically valid because of the loss of a certain amount of
data, we believe they provide useful information. However, we did not include
N0~ and NO data from House No. 3 because we judged the loss of data for these
pollutants at this house to be excessive.
In addition to the above data presentations, we plotted graphs showing
the time history of N0~, NO and CO for brief episodes in order to show the
direct dependence of indoor concentrations on stove usage.

4.0 RESULTS AND DISCUSSION
The sampling data were organized and evaluated in terms of several
different time averaging periods. The shortest time averaging period is the
five-minute average concentration of each pollutant at each of the four
sampling locations. For each sampling location there are three five-minute
average readings in each hour. We chose to compile these five-minute readings
into two-hour and daily averages in order to view the diurnal variation of
pollutant concentrations as well as to compare the measured values on a daily
basis.
The procedure for summarizing data was presented in Section 3.5. The
air quality data for each house are presented in Appendix B and are organized
as follows:
Appendix House No. Season
B-l 1 Spring-Summer
B-2 1 Fall-Winter
B-3 2 Spring-Summer
B-4 3 Spring-Summer
B-5 3 Fall-Winter
B-6 4 Fall-Winter
In each Appendix, the tables are organized for each of the pollutant
gases in the order of NO , NO, and CO.
In some instances, we have prepared graphs of the five-minute data
which illustrate short term episodes of interest. Finally, to provide a
more meaningful indication of the pollutant concentrations to which the home
occupants are exposed than would be shown by a hourly or daily average
concentrations, a frequency distribution of all the five-minute average data
for each pollutant was constructed.
4.1 House No. 1 - Suburban Split Level Home
During the spring-summer sampling period, the four sampling points
were located as follows:
1. Kitchen (approximately 1 Meter from stove)
2. Living Room
- 73 -
-------
3. Upstair-1 Bedroom
4. Outside
This was the first house we sampled in this program and early indica-
tions were that a kitchen sampling location directly above the stove would
produce peak values which would exceed the capability of the nitrogen oxides
sensing instrument. Thus, the sampling point was moved approximately 1 meter
away from the stove for the two-week spring-summer sampling period. At the
other three houses we found we were able to use a sampling point above the stove.
Between the spring-summer and fall-winter sampling period, the EPA
Project Officer requested that data be collected at somewhat different locations
during the fall period to provide additional data on diffusion of stove contami-
nants through the house. Thus , the sampling in the fall-winter period was some-
what different for each half of the two-week period as shown below:
FIRST HALF SECOND HALF
1. Kitchen - above stove 1. Kitchen - above stove
1A. Kitchen - approximately 1A. Kitchen - approximately
1 meter from stove 1 meter from stove
2. Living Room 3. Bedroom
4. Outside 4. Outside
4.1.1 Nitrogen Dioxide (N0?)
Tables 4-1 and 4-2 present data for House No. 1 during the spring-summer
and the fall-winter sampling periods respectively. Even though stove use data
for the second half of the fall sampling period were lost, the indoor/outdoor air
quality data for this portion of the sampling period are reported. It is apparent
in a general way from Tables 4-1 and 4-2 that N0« concentrations in this house are
strongly influenced by stove use. During the spring-summer sampling the periods
3
when daily average NO- concentrations in the kitchen were near or exceeded 100 pg/m
coincided with days of significant stove use.

In this table and all subsequent tables of this type the burner use times are
computed from the sum of all minutes of individual burner use during the day
shown, e.g., if during a day three burners were on for 10 minutes, two burners
on for 20 minutes, and one burner was on for 30 minutes, the total burner time
would be (3 x 10) + (2 x 20)+ 30 = 100 minutes.

-------
The same conclusion can be drawn for the fall-winter period, but it
is not nearly as clear cut as for the spring-summer period. Relatively less
stove use during the fall-winter period and higher outdoor N0_ levels as
compared to the spring-summer period contribute to a reduced indication of a
direct cause and effect relationship between indoor NO- and stove use. During
both sampling periods, there is an indication that the oven is more influential
than the burners in contributing to levels of NO,., indoors.
Outdoor concentrations appear to influence indoor concentrations to the
extent that they penetrate the structure and produce indoor "background"
levels to which indoor-generated N0« is added. This is shown in comparing the
patterns of indoor/outdoor NO. for May 12 and 15, 1973, in Table 4-1. These
were both days of relatively high and similar stove use, but outdoor N0?
3 3
concentrations were quite different: 44 Mg/m on May 12 and 73 pg/m on
May 15th. Kitchen concentrations were higher on May 15 by about the same
amount as outdoor concentrations as compared to May 12th. Furthermore, the
relatively high outdoor concentrations on May 12 prevented the bedroom
3
concentrations from getting below 78 yg/m on a daily basis.
If a similar analysis is attempted on data for the fall-winter
period (Table 4-2) it is not possible to show a clear-cut influence of outdoor
NO - levels on indoor concentrations. This can be attributed largely to the
house being closed up to a greater extent in November as compared with May.
Table 4-3 is presented to compare further the two sampling periods
in House No. 1 in terms of average values over the entire sampling periods.
In addition, we have computed non-kitchen values as a percent of the kitchen
value (either directly over the stove in the fall-winter or 1 meter from the stove

in the spring-simmer); indoor/outdoor ratios; and relative stove use during
the period.
Average stove use in the first half of the fall period was only 0.6
of the use in the spring. The ratio of fall to spring values for the
comparable kitchen locations (1 meter from stove) was 0.6 and for the living
room, 0.9. Although several interpretations of these values are possible
because of the complex interplay of a number of effects, the most logical
is that the more closed-up attitude of the house in the fall lessens dilution
of N0« as it diffuses through the house. Furthermore, the relatively low
concentrations inside the house during the fall relative to outside concentrations
tend to obscure any dilution effects. Also, note in the data for the fall
period (Table 4-2) that there are two instances where average living room
concentrations exceeded those at the remote kitchen location 1 meter from
the stove (See data for 11/7 and 11/8). On both days, outdoor NO- levels
were considerably below those indoors. We attribute this to a lack of dilution
of indoor air by outdoor air because the house is sealed relatively tightly.
Figures 4-1 and 4-2 are graphs showing the diurnal patterns of NO
in House No. 1 for the spring and first half of the fall periods respectively.
These graphs are based on a "composite day" which was developed from the
averages of all two-hour average values for a given time period for each of
the complete sampling days (no two-hour average values missing).
These graphs show clearly the rapid drop off of NO concentrations
between the kitchen and the living room during the spring and the more gradual
drop off between these two rooms in the fall. This presumably is the result
of the house being more tightly closed during the colder weather. Note also
the lack of a morning and noon kitchen peak during the fall period.

Figure 4-3 is a time history of a 4-day period during the spring
sampling at House No. 1, showing NO concentrations based on two-hour average
values together with data on stove use. This graph shows the immediate
response of the kitchen NCL levels to stove use. NO levels elsewhere indoors
also respond quickly to stove use. Analysis of the two-hour average NO
data shows that the greatest effect on indoor NO concentrations is caused by
the oven.
Figure 4-4, a graph of the two-hour average N0? concentrations during
a two-day period in the fall, further illustrates the effect of stove use on
the indoor air quality. As with the spring sampling period, the
oven creates the highest two-hour average N0? levels. When only the burners
on the stove were used, the average NO concentrations were noticeably less.
Note that on two occasions the 2-hour average N0? level at Station 2
(living room) exceeded one or both of the kitchen values. While part of this
is doubtless the effect of entrapment of N0_ within a relatively tightly
closed house, this apparent anomaly may have been caused in part by the
sequential nature of our sampling method. If the stove is turned on just
before Station 2 (living room) is sampled, this station will respond rapidly
to stove contributions. If the stove is turned off within the 10minute
period before Station 1 (kitchen over stove) is sampled, the level of N0_ in the
kitchen could drop below the earlier level in the living room.
A cursory examination of Figure 4-4 might give the impression that
outdoor concentrations are influenced by indoor generation. This is not

the case, but the converse Is true. Outdoor NO- levels reached peak values at
approximately the same times of day during both the summer and the fall sampling
periods. These peaks are associated with the time periods of greatest traffic
activity on nearby roads and are frequently coincident with times of meal
preparation at this house.
During inactive periods, NO concentrations were close to but slightly
greater than the outdoor NO- levels. This difference is attributable to the
pilot lights. Our laboratory study (Task 1) showed that the pilot lights
consume approximately 0.5 cubic feet(.014 cu M) of natural gas per hour.
A frequency distribution of all the five-minute NO data acquired
from House No. 1 was prepared to show the relative occurrence of various
NO 2 levels within this structure. Figure 4-5 is a log-probability graph of
the ML frequency distribution for all five-minute data at each of the four
sampling locations for the spring sampling period.
The graph shows that for any chosen percent of data less than a
given value, the sampling locations were arranged high to low in the same
order: kitchen, living room, bedroom, and outside, the expected
pattern. Although displaced in terms of concentration in the aforementioned
order, the three indoor locations have essentially parallel distributions
up to the 90% level. The living room and upper bedroom data are parallel
through their entire length but the kitchen has a noticeably divergence from
this general trend at the 90% level. This noticeable effect of indoor
generation on the distribution of NO concentrations measured in the kitchen
was not as evident in the data for the other indoor locations.
Figure 4-5 clearly shows that the NO- concentrations measured
indoors have a distribution quite distinct from the outdoor data. The kitchen
particularly reflects the influence of internal generation of NO- by the

stove with a significant number of observations above 100 yg/m .

We use 100 yg/m as a basis for comparing the frequency distribution of N0?
concentrations at various points in the house since this is the outdoor air
quality standard. While we are dealing with the indoor inhabited atmosphere
for which there is as yet no air quality standard, it is still part of the
total human exposure and use of an adopted outdoor standard based on human
health effects as a guideline for exposure seems appropriate at this time. If
o
greater than 50% of the values at a given sampling point are above 100 yg/m ,
it is conceivable that the arithmetic average of the 5-minute data would
exceed 100 yg/m . If these data are typical of long term occurrences, they
would then be considered to be reasonably representative of long term (annual)
exposures.
o
NO. levels in excess of 100 yg/m occurred in 16% of the data from
the kitchen, 9% of the data from the living room and 6% of the data from the
upperlevel bedroom. Except for a few isolated instances, no data in excess
3
of 100 yg/m were collected from Station 4, outside House No. 1
The frequency distribution of the N02 data for the fall sampling
period at House No. 1 was separated into two sub-periods, one for the time when
Station 2 was located in the living room (first half of sampling period), and
the other for Station 3 in the bedroom (second half of sampling period).
The results for the two sub-periods are shown In Figures 4-6 and 4-7 respectively.
With Station 2 in the living room (Figure 4-6), the N02 distribution curves
for each of the locations are quite similar and in fact intertwine with each
other in many instances. These distributed data do not shown the clear cut
separation as appeared in the spring sampling period.
Approximately 10 percent of the indoor data from all three locations
3
was in excess of 100 yg/m , which is less for Station 1 and slightly more
for Stations 1A & 2than was shown in the summer. As mentioned earlier, this
is primarily due to the lower level of stove activity during the fall as
compared with the spring. The relatively larger quantity of concentration
3
readings greater than 100 yg/m at the other indoor locations and the close
relationship of the indoor concentration distributions, again, appear to show

the effect of the house being in more of a closed-up attitude in the colder
weather.
The frequency distribution of NO data with Station 3 in the bedroom,
(Figure 4-7) shows a more distinct separation of the NO levels in the Kitchen
from the bedroom and outdoors. Fifteen percent of the station //I concentrations
were greater than 100 |ig/m , and eight, six, and five percent of the data from
Stations 2,3, and 4 respectively, were in excess of 100 yg/m . The upper
level bedroom, the farthest possible location from the stove within this house,
shows relatively high independence from the outdoor ambient NO levels through
the top 50% of the data.
4.1.2 Nitric Oxide (NO)
Table 4-4 presents a summary of the daily average NO concentrations
for the six full days of spring sampling at House No. 1. Over this sampling
period, the NO concentration in the kitchen was approximately four times the
average NO level outside the structure. In comparing Table 4-4 with 4-1, the
overall indoor concentrations of NO and N0_ are about equal for this sampling
period. However, the overall outdoor NO,, concentration is almost twice the
outdoor NO concentration. While most sources of nitrogen oxides generate
much more NO than NO with eventual conversion of NO to NO in the atmosphere,
TRC's laboratory investigations of stove operations (Task 1) indicate that the
NO and NO,., are formed in nearly equal amounts over a wide range of stove
operating conditions.
Comparison of stove use and daily NO concentrations yeilds about the
same correlations as was earlier noted with respect to N0». In general, the
highest daily NO concentrations were associated with days of high stove usage.
Table 4-5 shows a summary of the daily average NO concentrations
for the fall sampling period at House No. 1. Overall, the NO concentrations
during the fall were substantially greater both indoors and outside during the
fall than they were in the spring. The outside NO concentration was more than
twice as high as that measured in the spring. Conservation of NO within the
kitchen was more apparent than for NO,,.

The effect of ambient outdoor NO levels on the indoor NO concentration
is somewhat different than appeared with the N02. In Table 4-5 we see that
two days of similar stove activity, 7 November and 12 November, had substantially
different NO levels outdoors and subsequently, indoors as well. Outdoor NO
levels on 12 November averaged 5 times those recorded on 7 November. On each
3
of these days, NO levels at Station 1 were approximately 70 yg/m higher
than ambient levels outdoors on the same day. The direct influence is dampened
somewhat by the relatively isolated indoor environment caused by closed doors
and windows during the colder season.
Table 4-6 is organized similarly to Table 4-3 for NO- and is based
on averages for entire sampling periods. In comparing Table 4-6 with Table 4-3,
one is struck with the extreme complexity of the indoor/outdoor patterns
of NO and NO-. Thus, interpretations must be made largely on the basis of
experienced judgment together with data which appear to show some trends.
The principal variables which affect indoor patterns of NO and N0_ are:
1. Stove use
2. Permeability of the house (higher in spring than in fall)
3. Indoor/outdoor ratio
4. Loss of pollutant through reaction, adsorption, and other
mechanisms
In Table 4-3, note that outdoor concentrations of NO- are about the
same for spring and fall, but fall concentrations of NO as shown in Table 4-6
are more than twice the average for the spring. While an analysis of the
meteorology and the details of outdoor air quality are outside the scope of
this program, we presume that the warmer weather, higher incidence of sunlight

and photochemical processes contributed to the more complete conversion of
NO to N0_ in the spring as compared with the fall.
In comparing the "percent" of remote kitchen value" for NO in the spring
and fall in Table 4-6, there is a drop to 63% in the spring and 70% in the
fall. This is presumed to be the joint effect of higher house permeability
in the spring and higher outdoor NO levels in the fall.
A graph of the two-hour average NO concentrations versus time for the
same time period in the spring as shown earlier for N02 (Figure 4-3) is
presented in Figure 4-8. Comparison of the two figures (4-3 and 4-8) shows
them to be basically similar with common peaks and analogous traces. Stove
use readily affected the indoor NO levels and the behaviour of the NO with
time and distance from the source was the same during both periods.
We do not present a typical time history for NO during the fall since
such a graph would not add significantly to our basic knowledge.
Comparison of NO and N09 two-hour averaged data in addition to the
graphical data also shows that the total oxides of nitrogen (NO and N0?) did
not remain constant during and after stove operation but increased and declined
with stove use. This observation is evidence that the generation and diffusion
of NO- rather than conversion of NO to N09 is the predominant source of indoor
N02. The conversion of NO to NO. by reaction with atmospheric oxygen is inhibited
by the lack of sunlight available inside the house to promote that reaction.
A frequency distribution of the five-minute average NO data obtained
during the spring sampling period at House No. 1 is shown in Figure 4-9. The NO
3 3
concentrations measured in the kitchen ranged from 4 ug/m to 500 yg/m . Although
Tf
the distribtuions of NO and NO- concentrations in the spring are somewhat
similar, one notable difference between the two sets of data is the uniform

distribution of the kitchen NO data compared to the abrupt increase in NO
levels at high concentrations. This observation may be explained by our results
from laboratory study of stove operations which indicate that some stove
operating conditions generate more N0_ than NO.
The frequency distribution of the five-minute NO data from the fall
sampling period with Station 2 in the living room is presented in Figure 4-10.
Figure 4-11 is a graph of the frequency distribution of five-minute NO data
with Station 3 located in the bedroom of House No. 1. Figure 4-10 shows the
very close relationship between Stations 1 and 1A. Nitric oxide is shown as
relatively inert and is conserved well in its diffusion into the kitchen from
the stove. The living room has a distinctly lower occurrence of a specific
NO concentration than the kitchen. All of the indoor locations in both
sampling periods showed higher NO concentrations than occurred outdoors. The
frequency distribution presenting NO data when Station 3 was located in the
bedroom (Figure 4-11) shows the three indoor locations as more closely related
than during the earlier sampling. Approximately 60% of the indoor NO concentrations
3
were less than 100 yg/m during this week of sampling.* The earlier week's
sampling, with Station 2 in the living room (Figure 4-10) showed NO concentrations
3
less than 100 yg/m only 40% to 60% of the time. During the spring sampling
period, the indoor NO levels were less than 100 yg/m for 70-80% of the time.
Generally, the occurrence of higher NO concentrations indoors during the fall
is caused by the higher background NO levels present outdoors and the more
tightly closed attitude of the house in the fall.
3
*The 100 yg/m is not significant for NO since there is no ambient air quality
standard for this pollutant. However, it is convenient to use this concen-
tration as a basis for comparison since it is the ambient air quality standard
for N09 (annual average) and NO and NO- and generated together in gas flames.

4.1.3 Carbon Monoxide (CO)
The daily average carbon monoxide levels for the spring sampling
period at House No. 1 are compiled in Table 4-7. Over the entire spring
sampling period at House No. 1, the daily average carbon monoxide concentration
in the kitchen was approximately 1.3 times greater than the daily average
CO concentration outside the structure. This is considerably less than the
ratio between kitchen and outdoor concentrations for NO- and NO. (2.3 and
3.9 respectively for the same period)
An examination of the two-hour time averaged data contained in
Appendix B-l also shows that the CO generated within the house was not as
widespread as were the two oxides of nitrogen. The carbon monoxide levels
generally did not increase at rates similar to NO and NO and in some
cases did not reach peak levels until after the stove was shut off. The
rates of increase of CO concentrations in the living room and bedroom were
similar to the rate of increase in the kitchen.
Table 4-8 is a summary of the daily average CO concentrations at
House No. 1 during the fall sampling period. In spite of a considerably
lower level of stove activity during the first half of this sampling period,
carbon monoxide levels were about the same indoors but lower outdoors when
compared to the spring data. During the second half of the fall sampling
period when stove use data were not available, the indoor CO levels again were
similar to those in the spring but the outdoor levels were lower. CO levels in
the kitchen average 2.5 times greater than outdoors during the first part of
the fall sampling period. Stations 1 and 1A showed a similarity in average
CO levels that were comparable to those measured for NO, with Station 1A
averaging concentrations that were 84% and 88% of those measured directly over
the stove for the first and second halves of the fall period. As demonstrated
with N02 and NO, the indoor CO levels at various indoor locations were much

..loser to each other during the fall than in the summer. This shows the effect
of a more sealed up attitude of the house in the fall as compared with the
spring.
As noted earlier, CO concentrations at House No. 1 during the fall do
not appear to peak as fast as NO and NO. In several cases, CO levels did not
reach peak values until after the stove was shut off. The rate of increase of
CO levels indoors was similar for all locations.
Table 4-9 summarizes CO concentrations and stove use data for House
No. 1 for both the spring and fall sampling periods. Because of less stove use
in the fall (first half of period), indoor concentrations of CO are slightly
lower in the fall as compared to the spring. However, the indoor/outdoor ratio
is much higher for the fall data which reflects the more tightly closed aspect
of the house in the fall. Also it appears that there are other sources of
indoor CO besides the stove. This house was used in the first indoor/outdoor
air quality study conducted by TRC* and we found that the attached garage in
this house could contribute significantly to indoor CO concentrations under
certain circumstances. It is conceivable that auto exhausts entrapped in the
garage, in diffusing through the house, add to the levels of indoor CO. Such
an effect will be enhanced by cold weather when the warm house acts like a
"stack" and can induce air from the garage at the lower level and spread it
through the house.
We do not present any typical CO time histories for House No. 1 but
the two-hour average data for the spring and fall are presented in Appendices
B-l and B-2 respectively.

Figures 4-12, 4-13, and 4-14 are cumulative frequency distributions
of the five-minute averaged CO data from House No. 1 during the spring, the fall
with Station 2 in the living room, and the fall with Station 3 in the bedroom,
respectively. The two distributions from the two fall periods have similar
shapes, but the curves for spring measurements drop off sharply for low
values. For each sampling period, the three indoor locations had very similar
frequency of occurrences of specific concentrations. This illustrates the
relative independence of CO concentrations from the sampling location as
compared to N02 and NO for five-minute periods. For the fall distributions,
the curves for the three indoor locations are closely grouped and there is a
greater difference between the grouped indoor curves and the outdoor curve
than was shown in the spring data.
4.2 House No. 2 Urban Two Story Home
4.2.1 Nitrogen Dioxide (NO )
Fall sampling was not carried out at this house since the amount of
stove use by the single occupant was not sufficient to make an adequate evaluation.
Table 4-10 presents the daily averages of NO- at House No. 2. It
ic readily apparent that there is little difference in the concentrations
measured at the four locations when averaged over a day. Outdoor
N02 concentrations were about twice as high at House No. 2 compared to the
other structures. This reflects the urban location and proximity of House No. 2
to local traffic arteries. The frequency of stove use was considerably less
than for House No. 1 and this appeared to be the reason for the uniformity
until we examined the two-hour averaged data.
Figure 4-15 is a graph of a portion of the two-hour averaged data
included in Appendix B-3. It shows the specific influence of stove

operating periods on the kitchen locations and to a lesser extent on the
other indoor locations. This figure also shows the uniformity of concentrations
for all four sampling locations when the stove is not being used. By contrast,
our results from the other two structures show a consistent difference between
kitchen and outdoor NO- concentrations during inactive stove use periods.
The explanation for the different observations was developed after evaluating
stove operation in each house. Houses No. 1,3, and 4 have relatively new
stoves, each with three continuous automatic pilot lights, one for each pair
of burners and one for the oven/broiler. The much older stove in House No. 2,
however, has only a single manual pilot which must be activated first before
igniting a burner. This type of pilot uses very little gas and therefore
generates only a small amount of NO compared to the multiple continuous pilots
of the newer stoves which generate enough NO to maintain a kitchen concentration
higher than outside levels.
A frequency distribution of the five-minute averaged NO data for the
spring data at House No. 2 is presented in Figure 4-16. The distribution of
concentrations is identical for all four locations for about 90% of the
observations. Approximately 50% of the NO levels measured at all four locations
were greater than 100 yg/m . Similar to House No. 1, the kitchen had a
greater frequency of NO concentration above 100 yg/m than the other sampling
locations. We attribute the uniformity of the distributions for all four
locations to both lack of stove use as well as the absence of multiple,
continuous pilot lights on the stove.

the kitchen during the sampling period was greater than the overall outside
NO concentration by 70%. The contribution of the stove to NO concentrations
in the kitchen is more apparent than for NO . Outdoor NO concentrations were
much lower than the corresponding N0» values during the sampling period and
therefore ambient NO penetration did not influence the kitchen NO concentrations
as greatly as ambient NO^ influenced the kitchen NO measurements.
A graph of the two-hour average NO concentration for a two-day period
at House No. 2 is presented in Figure 4-17. A tabulation of the two-hour
averages for the entire sampling period at House No. 2 is in Appendix B-3.. The
graph shows that the generation and diffusion of NO followed a pattern similar
In comparing Figure 4-17 with Figure 4-15, the higher ambient NO causes the
indoor NO levels to be much higher than NO indoor concentrations during
periods of stove inactivity.
Figure 4-18 is a graph of the frequency distribution of the five-
minute NO data from House No. 2. The distributions of the four sampling
locations are not identical but certainly very similar. The kitchen has
slightly greater frequency for higher NO concentrations than the other three
3
sampling locations particularly above 200 yg/m .
4.2.3 Carbon Monoxide (CO)
A summary of the carbon monoxide daily averages at House No. 2 is
given in Table 4-12. There is little difference in the concentrations measured
at the three indoor and one outdoor locations. In fact, on the day of highest
stove usage, (5/30), the daily average in the kitchen is somewhat lower
than the outside concentration. Outdoor CO concentrations greatly
influenced the indoor concentrations.

Figute 4-19 Is a graph of the two»hour average CO concentrations
for a two-day period at House No. 2. Appendix B-3 contains all of the two-hour
averaged data for the sampling period. The time variation of CO is very similar
to that of NO. The outdoor concentrations fluctuate considerably and the indoor
concentrations at the three locations generally follow the outdoor pattern.
The influence of the stove on indoor CO concentrations is shown briefly during
operating periods and afterwards the indoor concentration rapidly declines to
the outdoor CO concentration.
Figure 4-20 is a frequency distribution of all the five-minute CO
data recorded at House No. 2. The four curves for the four sampling locations
are closely spaced and frequently cross each other. The occurrence of any
specific concentration was fairly uniform irregardless of sampling location.
Overall stove inactivity was responsible for the close proximity of the
indoor concentration to the outdoor CO levels.
4.2.4 N02, NO, CO Diffusion Experiment
Although the small amount of stove usage at House No. 2 produced a
disappointingly small amount of interesting data, the relative inactivity
gave us an excellent opportunity to conduct a diffusion experiment. The
purpose of this experiment was to study the behavior of the 3 pollutants as
they diffused through the house and became diluted with outdoor air.
We operated all five burners of the stove for a period of 71 minutes
until pollutant concentrations in the kitchen approached a maximum. The
burners were then shut off and the sampling for N09, NO and CO continued
until the indoor concentrations returned to their former levels.
Table 4-13 shows the peak values measured at each indoor sampling
location before the burners were shut off. The living room and bedroom

concentrations are also expressed as percentages of the peak kitchen
concentration for each pollutant. The living room and bedroom peak values showed
that both CO and NO were conserved to a considerably greater extent than NO^
as they diffused through the house. NO disappears either through reaction or
surface adsorption as it diffuses through the house.
Figures 4-21, 4-22 and 4-23 show graphically the time history of
the NO , NO and CO concentrations respectively during the diffusion experiment
at House No. 2. All of the indoor sampling locations showed sharply increased
pollutant concentrations within the first five-minute sampling period at
each location and all locations had a similar decay rate for the same
pollutant when the burners were shut off.
The NO- exhibited the most rapid decay; it reached pre-experiment
levels about 2 1/2 hours from the time the stove was turned off. The CO
required about 7 hours to return to previous levels and the NO about
8 hours. From the shapes of the three curves, we computed that the half life
of CO in the house was 2.1 hours. Since CO is unreactive, this half life represents
loss solely through diffusion and dilution. The half lives for NO and N07
were 1.8 and 0.6 hours respectively. The behavior of NO is quite similar
to that of CO. Thus, the oxidation of NO to NO- or loss through other
mechanisms is not significant. NO ,. on the other hand, is lost relatively
rapidly. Among the possible mechanisms for the depletion of N0« is the
formation of nitrate and/or nitrite aerosol. Such a mechanism might be
enhanced by the high moisture content of kitchens with gas stoves water
vapor production associated with cooking, and that produced as a by product
in the combustion of natural gas. Some of our data from the other structures
show more N0_ than NO present during inactive stove use periods which perhaps
can only be explained by the generation of more NO than NO from the pilot
lights since NO,, should disappear more rapidly than NO when neither are being
generated.

4.3 House No. 3 Suburban Two-Story Apartment
4.3.1 Nitrogen Dioxide (N02)
Tables 4-14 and 4-15 show respectively the summer and fall daily
average data for NCL at House No. 3. In addition we present Table 4-16
which summarizes the data for both seasons to facilitate their comparison.
Because of severe instrument malfunction problems in this house we had
available only two complete days of sampling during the spring-summer
period and one and three days respectively during each of the two fall
periods. Nevertheless, we believe it is still possible to draw conclu-
sions from the available data on the effect of stove use and outdoor air
quality on the concentrations of pollutants found inside this house.
Q
Concentrations of N02 in the kitchen of this home exceeded 100 ug/mj
even when the stove is little used. Note that on 6/22 the daily average
kitchen concentrations exceed 100 Pg/m with only 5 minutes of stove use.
However, at this time outdoor concentrations were relatively high (60 vig/m-5).
In this connection, we point out that outdoor concentrations were higher in
the spring-summer period than the fall-winter period. These conditions are
the reverse of those encountered while sampling at House No. 1.
One reason for the elevated N02 readings in the kitchen of this house
in spite of a low level of stove use is undoubtedly the stove pilot lights.
Another reason for this effect is the configuration of the kitchen. This
kitchen is a small, unventilated workspace that is relatively isolated from
the rest of the living quarters. This configuration appears to inhibit the
diffusion of N02 into the other rooms. The sharp drop in measured N0_ con-
centration from the kitchen to the other indoor sampling locations is further
evidence of the slow diffusion of kitchen air to the rest of the apartment.

Indoor sampling locations, outside of the kitchen, had overall average N0?
levels during both sampling periods that were noticeably lower than the
other three structures despite the high concentration in the kitchen.
In Table 4-16 we see that the overall average NOo concentration in
the living room during the summer was 66% of the corresponding N0£ concen-
tration directly over the stove. In the first part of the fall sampling
period, at the same location, the N02 level was only 53% of that measured
directly over the stove. This could be the result of the occupant sealing
off direct access to the living room from the kitchen with a plywood section
between the spring and fall sampling periods. However, such a conclusion is
somewhat conjectural in view of the limited number of complete sampling days
available.
A comparison of indoor/outdoor ratios in the spring and fall (2nd
half) shows the joint effect of stove use and permeability of the apartment.
Note that in the spring the indoor/outdoor ratio for the kitchen is about 2
but drops to almost 1 in the bedroom. In the second half of the fall the
ratio exceeds 5 in the kitchen corresponding to a 7 times higher stove use
than in the spring, but the indoor /outdoor ratio in the bedroom remains above
2 in the fall presumably because of the decreased permeability.
Figure 4-24 is a graph of some of the typical two hour average N02
data from the spring sampling period at House No. 3. The graph shows how
short burner operating times result in considerable increases in N0« concen-
trations in the kitchen which decay very slowly and consistantly remain
higher than outside and other indoor NC^ concentrations. We suspect that
the limited kitchen ventilation and the pilot lights are responsible for
the increased concentrations of N0 in the kitchen of this house.

Figure 4-25 presents a more detailed look at a portion of the data
contained in Figure 4-24 by utilizing the five-minute data obtained directly
from the strip charts. The immediate response to stove operation is quite
evident by observing the kitchen trace at approximately 0815. Notice that
approximately one hour earlier the living room NC>2 concentration shows a sharp
peak. Examination of the stove use log kept by the occupants and the original
strip chart showed that one burner was turned on for 4 minutes at the same time
the living room sampling location was in its 5 minute active mode. No effect
of this brief stove use is recorded by the kitchen since the kitchen location
was not actively sampling until 15 minutes later. During periods when the stove
is inactive the indoor and outdoor concentrations generally rise and fall
together which shows the influence of outdoor N02 penetrating the structure.
At all times, however, a sharp differential existed between the kitchen and
outdoor concentrations.
In view of the considerable loss of N02 data at this house at non-
random times, we do not present frequency distributions for N02 at House No. 3.
4.3.2 Nitric oxide (NO)
Tables 4-17 and 4-18 present the daily average data for NO at House No. 3
during the spring-summer and fall-winter periods respectively. Table 4-19
summarizes the average data from both periods to facilitate comparisons. As in
the case of NO-, there are relatively few complete days during each sampling
period on which to base our evaluations.
While outdoor N02 levels were 1/3 greater in the summer than in the winter,
outdoor NO was about the same during the spring and second half of the fall
period and about twice as high in the first part of the fall period as compared
to either of the other two periods. These relatively higher outdoor concentra-
tions account for some of the higher indoor levels of NO found in the winter

but in addition the apartment being less permeable in the winter also allows
build up of NO indoors. To illustrate this point, note the pattern of
indoor/outdoor ratios for the spring and second half of the fall in Table
4-19. As in the case of N02 (see Table 4-16) this comparison shows the
joint influence of stove use and house permeability.. In addition in com-
paring these two tables we can see clearly the difference in behavior of NO
and NO-. Recall that in the spring the indoor/outdoor ratio for N0£ dropped
to almost 1 in the bedroom. While there is a significant drop in this ratio
between the kitchen and bedroom for NO during this period, the bedroom ratio
is 40 percent higher for NO than N02. This difference is shown even more
clearly in comparing indoor/outdoor ratios for NO and N0£ in the second half
of the fall period. The ratio for NO drops from 5.5 to 3.2 between the
kitchen and the bedroom while that for N02 drops from 5.6 to 2.2. These
observations substantiate the results of the diffusion experiment carried
out in House No. 2 where we noted the reduced half Life of N02 as compared
with that of NO.
A graph of the two-hour average data from the spring shown in Figure
4-26 is essentially similar in shape to Figure 4-24 for NOn. The only signif-
icant difference is that there is not as sharp a drop in concentrations
between the kitchen and the other rooms of the house. This phenomenon, we
believe, illustrates the difference in decay characteristics of NO and N02 as
discussed elsewhere in the report.
As in the case of NOo we do not present frequency distributions for
NO because of the limited data here.

Table 4-22 summarizes the data from all sampling periods.
Indoor CO concentrations are more strongly influenced by outdoor con-
centrations than by stove use. This experience is similar to that from the
other houses. In contrast to v- *T^. 1, the fall-winter CO levels out-
side were somewhat higher than those measured in the spring. We attribute
this to differences in the meteorological conditions in the two separate
sampling periods.
The indoor kitchen concentrations for the fall sampling period
approached the air quality standard of 10,000 pg/m^ for an 8-hour averaging
period. This was due primarily to the high level of carbon monoxide measured
outdoors. A secondary reason is the isolation of the kitchen from the rest of
the living space. This results in less diffusion and dilution of the stove
effluent. Overall, the contribution of carbon monoxide by the stove is of the
same order as originally measured by TRC in 1969 and 1970 in our earlier study.*
Frequency distributions of the CO data at House No. 3 for the summer and
first and the second week of the fall sampling periods, are presented in Figures
4-27} 4-28, and 4-29 respectively. We did not experience the same loss of
CO data that we had for N0£ and NO at this house. Tabulations of all two-hour
average CO data for House No. 3 for the summer and fall sampling periods are
presented in Appendices B-4 and B-5 respectively.
All three of these distributions are basically similar in shape except
that the fall frequency distributions, Figures 4-28 and 4-29, show signifi-
cantly higher concentrations, furthermore, there is greater separation of the

grouped indoor distribution curves as related to the outdoor curves in the
fall than in the spring. This result is probably the result of the more
closed up attitude of the house in the fall as compared to the spring.
4-4 House No. 4 - Suburban Ranch Home
We chose this house to replace House No. 2 for the fall-winter 1974
sampling period. The following locations were selected for the entire two
week sampling period at this house:
Station 1. Kitchen-above the stove
Station 1A. Kitchen-1 meter from the stove, over the sink
Station 2. Living Room
Station 4. Outside
Sampling In one of the two bedrooms for half the test period was not
possible because of the inconvenience it would have caused the residents.
4.4.1 Nitrogen Dioxide (N02)
Table 4-23 is a summary of the daily average N0£ and stove use data
for seven complete days during the winter sampling period. The overall
3
average NCL concentration in the kitchen, 213 jig/m , was the highest for all
the houses tested in this task. This overall average was approximately 5.5
times greater than the outdoor N02 level of 39 ug/m^. As we found from
sampling at the other three houses, the NC^ levels indoors are In-
creased by stove usage. Stove age and condition are also factors contri-
buting to the high NC>2 levels at House No. 4. The level of stove activity,
an average of 66 oven minutes and 73 burner minutes per day, was one of the
highest that we encountered in the field sampling program. Stove use in

in House No. i was about the same as the winter use level in House No. 4.
The daily average NO concentrations were generally highest on days
of high stove activity. Another factor affecting the indoor average N0~
levels was the corresponding concentration outside, but such an effect
could not be established with precision based on the available data.
Comparison of the twenty-four hour averages for each of the four
sampling locations shows a sharp decline in N0« levels within a short distance
from the stove. Station 1A was 1 meter from the stove and the average NO,,
concentration decreased 44% from the levels measured directly above the
stove. We did not observe this sharp drop in NO. within the kitchen
(comparing concentrations at Station 1 with Station 1A) at either House No. 1
or No. 3.and initially believed that the outside door located close to the
stove was diluting stove effluents since neither of the other houses had this
configuration. However, as we shall see later this apparent dilution effect
did not show up with either NO or CO. Therefore, the outside kitchen door
cannot be considered as an important factor in affecting the pattern of
indoor concentrations in House No. 4. We believe that the rapid disappearance
of NO generated by the stove in this house is enhanced by mechanisms such as
adsorption, absorption and reactions which are not present in the other houses.
One possible explanation might be the effect of high humidity within the
kitchen of this house. Sampling was done during cold weather when the house
was tightly closed, and with the considerable amount of cooking done in this
house, the relative humidity in the kitchen could have been quite high which
in turn might have enhanced the disappearance of N0~ by one of several mechan-
isms. The relative higher temperature in the kitchen should not be discounted
as a contributory factor.
Figure 4-30 shows the diurnal pattern of N0» concentrations in House
No. 4 in winter. This graph like the others of this type presented earlier

for House No. 1 (Figures 4-1 and 4-2) are based on a "composite day"
developed from 7 days of data. This graph shows the dominant influence of
the peak associated with preparation of the evening meal. We are not able
to explain the dip in the NC^ value in the kitchen 1 meter from the stove
'(and to a lesser degree in the living room) which occurs in the early
afternoon.
Figure 4-31 is a graph of 2-hour average NO concentrations for a
typical period at House No. 4. As we found at the other houses, N07 levels
immediately respond to stove activity. This stove use also becomes readily
apparent as N02 concentrations increase throughout the house. Periods of
intense activity generally create higher concentrations. But these peak
levels did not persist after the stove was turned off. The graph also shows
the distinctly higher concentration found at Station 1, and the more closely
related NO- levels elsewhere indoors. A complete list of the 2-hour NO-
averages can be found in Appendix B-6.
Figure 4-32 is a frequency distribution of all of the five-minute
averaged NO,, data. This distribution shows that 70% of all the five-minute
3
NO. data in the kitchen above the stove was in excess of 100 ug/m . Note
that there is a logical separation of curves for the kitchen (over the stove)
and the living room. However, the curve for the kitchen location near the
door does not have a logical relationship to the others. As we mentioned
before, the rapid loss of NO- between Stations L and 1A for unexplained
reasons causes this apparent anomaly.
4.4.2 Nitric Oxide (NO)
Table 4-24 summarizes the daily average NO levels and the stove use
data at House No. 4. As we found with NO-, the NO levels at this house were
the highest we encountered in the field sampling program. NO levels at
Station 1 averaged 14 times greater than those outside. As with NO- these
high average NO concentrations are caused primarily by the high levels of
stove activity with stove age as a contributing factor also. A complete
listing of the 2-hour average NO concentrations can be found in Appendix B-6.

The conservative behavior of NO as compared with NCL is demonstrated
by comparing the relationships of living room to kitchen (over the stove) for
NO with NO- as shown in Tables 4-24 and 4-23. The living room value for NO
is 51 per cent of the kitchen value, and for NO- the living room value is
only 33 per cent of the kitchen value.
Figure 4-33 is a graph of the two-hour average NO concentrations for
the same time period as shown for NO- in Figure 4-30. Comparing these two
graphs shows peaks occurring in the same time periods of stove use. However,
NO obviously does not decay as rapidly as NO- as stove effluents diffuse
through the house. This confirms our previous findings in the diffusion
experiment we conducted at House No. 2 in which the NO half-life was about
three times greater than the half-life of N0~. The two-hour NO averages
indoors are much more closely related than shown for NO-. They are also
much higher than the outdoor NO levels during this time period.
A frequency distribution of all five-minute averaged NO data is shown
in Figure 4-34. The most striking characteristic shown in this graph is the
wide separation between indoor and outdoor concentrations. With all three
indoor locations having basically similar occurrences of any given NO con-
centration, our earlier observations are further substantiated.
4.4.3 Carbon Monoxide
The daily average carbon monoxide concentrations at House No. 4 are
presented in Table 4-25. As we found in the case of NO, carbon monoxide levels
were exceedingly high indoors. The overall average CO concentration above the
stove was approximately 3.8 times the overall average measured outdoors. This
is substantially higher than we found at the other three houses. Carbon monoxide
levels at House No. 4 appear closely related to stove use. The stove as the
primary cause of high indoor CO levels can be seen by comparing the daily average
concentration for February 1 and February 2. On February 1 the outdoor CO con-
centration was somewhat lower than that on February 2, yet kitchen concentrations

(over the stove) were higher on the 1st as compared to the 2nd because of the
higher stove use. The interplay between indoor and outdoor CO concentration is
probably minimized during the colder season when the house is closed up. At
this time, the indoor CO levels are more responsive to stove activity.
The behavior of carbon monoAxue onows it to be even more persistant than
NO. As shown in Table 4-25 indoor CO levels averaged within 90% of the concen-
tration directly above the stove. On several days the average CO concentration
was higher at the remote kitchen location than directly above the stove. The
reasons for this are not clear and some characteristics of the specific situation
are unknown.
Figure 4-35 shows a time history of 2-hour average CO concentrations for
a typical sampling period at House No. 4. This graph shows clearly the conser-
vative nature of CO especially when compared to the time histories for N0? and
NO for the same period (Figures 4-31 and 4-33). In fact, the CO time histories
for the three indoor locations are almost identical and distinctly separate from
the outside values. Figure 4-35 also shows the increases in CO levels with stove
use. Carbon monoxide levels decrease after stove use more slowly than NO,, but
similar to NO. The CO concentrations at the indoor sampling locations appear to
increase and decrease in unison with incidents of stove use. The compilation of
all the two-hour CO averages is in Appendix B-6.
Frequency distributions of all the five-minute averaged CO data are shown
in Figure 4-36. In this format of data evaluation, we see again the similarities
between CO and NO (compare with Figure 4-34). All three indoor CO levels cor-
respond closely and are distinctly higher than the outside values. Approximately
3
40% of the indoor concentrations are in excess of 10,000 ug/m .

TASK 3 - INVENTORY OF INDOOR SOURCES
1.0 INTRODUCTION
The purpose of this task is to identify actual and potential sources
of indoor air contamination other than gas stove emissions. These sources were
to be identified in two of the homes where indoor/outdoor sampling was carried
out. Then, based on the results of this general and preliminary survey, those
source categories judged to be important in determining indoor air quality and
which could be quantified were to be studied in greater detail by an analysis
of their activities in the homes of TRC employees.
In the course of the study we determined that the indoor source other
than gas stoves which appeared to be most significant and was amenable to
quantification was the use of aerosol products. Therefore, the bulk of this
task was devoted to this indoor source category.
- 163 -
-------
2 r SUMMARY AND CONCLUSIONS
We have carried out a two-phase study to identify and, to the
extent possible, quantify sources of indoor air contamination. We found
that potential indoor sources take many forms. The emissions characteristics
are highly variable and are related to c* */ide range of household operations.
The one category of source found to be common to the households surveyed and
which promised to be reasonably quantifiable was the use of products
dispensed as aerosols by propellants.
Estimates were made for emissions of propellants into indoor atmospheres
based on a survey of aerosol use patterns among TRC employees.
From the results of this work we draw the following conclusions:
1. Indoor sources of air contamination take many forms and are
highly variable as to location in the home, intensity and
frequency.
2. Quantification of indoor emissions of air contaminants is not
straightforward and much more work is needed in developing
appropriate emission factors.
3. The most common and important sources of indoor air
contamination were identified as:
a. Smoking
b. House cleaning activities
c. Cooking
d. Use of aerosol products
4. Of the important source categories identified, the only one whose
quantification could be attempted within the scope of this study
was use of aerosol products.
- 164 -
-------
5. A wide range of "active" ingredients and to a lesser extent pro-
pellants are used in aerosol form. We were able to determine
typical active ingredients for many aerosol products but not
specific quantities of each ingredient. For this reason no quan-
titative estimates of emissions were made for the active ingredients.
6. Fluorocarbon propellants are used in an estimated 75 percent or more
of the aerosol products. Other propellants are used but in much
smaller quantities.
7. Based on aerosol use data in a survey of TRC employees, we conclude
that propellant concentrations in the home are usually well below
the TLV's for these materials. However, combinations of circumstances
could produce concentrations approaching or exceeding these levels.
8. The co-existence of aerosol product active ingredients, propellants,
and contaminants from other sources in the home could produce an
environment capable of producing adverse health effects. This whole
area needs further study.

3.0 SURVEY RESULTS
3.1 Preliminary Interviews and Inspections
The two houses chosen for a generalized survey in indoor sources
were House Nos. 1 and 3. A general description of their lay-out and other
physical aspects is included in the Task 2 report.
In surveying the two houses, we used a list of possible sources of
indoor air contamination as a basis for our interviews with the homeowners.
This list is shown as Table 3-1.
Table 3-2 presents the results of interviews with the householders in
Houses 1 and 3 based upon the format presented in Table 3-1. As one might
expect, there is considerable variability in the habits and practices in
these two homes which are capable of creating indoor air contamination.
We discussed this survey with many TRC employees and determined that the
variability (in character, time, degree and location) in practices which can
cause indoor air contamination is typical.
Many of the sources were deemed to be extremely intermittent (e.g.,
interior painting) or so variable in nature (e.g, hobby and home repair
activities),at least among TRC employees, that further detailed considerations
within this task would have yielded little useful information. We also
found that the incidence of smokers among the TRC staff and their families
was extremely low (less than 10%) and pursuing this potential source in detail
within the population under study would have yielded little information.
We identified cooking, cleaning and the widespread use of products
dispensed with propellants as important and common sources of indoor air con-
tamination. The first two source categories can take many forms.

Quantification of these indoor emissions could only be determined by means
of laboratory and field measurement programs and developing adequate data on
these relative importance in influencing indoor air quality would be outside
of the scope of this project. Therefore, we identified the use of aerosol
products in the home as the category to be studied further.
3.2 Aerosol Product Survey
The use of aerosol products was shown to be prevalent among the TRC
employees interviewed. The variety of products dispensed from pressurized
containers has grown remarkably in the past ten years or so and are associated
with many household and personal care uses. Since the average family employs
a significant number of aerosol products which directly dispense material into
the home air environment, TRC decided to investigate further their emissions.
A checklist of common spray products was distributed among the employees
at TRC and the responses from nearly 40 households were evaluated. Information
was gathered on the usage habits (rate of use, time of use, and the
frequency of use) from which estimates of the quantity of contaminants emitted
to the indoor environment were obtained. We believe that this inventory
represents a cross-section of middle-class Southern New England homes.
3.2.1 Design of the Survey
A check list was prepared and distributed among the employees at TRC.
Information on the usage habits of each household with respect to aerosol
products was recorded. The following product areas appeared on the check list:

We noted the usage rates, location of use, and the frequency and time of use
for each product used by the households interviewed. Information regarding the
makeup of the households was also recorded.
3.2.2 Results and Discussions
General Characteristics
The inventory consisted of responses from approximately 40 households
which represent essentially half of TRC's employees. Statistics on the households
appear in Table 3-3.
Usage habits of aerosol products among the households surveyed showed
that essentially all families use some aerosol spray product of one kind or
another. The data showed that an average of 10 product categories are used
by each household. Table 3-4 presents the most frequently reported aerosol
products. Six of the nine categories appearing come under the heading of
household cleaning aids. This is of particular consequence since this would
necessarily subject the housewife to a good number of potential air contaminants
during the course of the day. Another major class of spray products is the
Personal Care Category with contributions from deodorant sprays, hair sprays, arid
shaving foams.

Emission Characteristics
Some aerosol products are limited or confined to specific locations of use
in the house. Others are used throughout the residence. The time, frequency,
and rate of use are also shown to vary among spray products. For the most
part, deodorants and shaving foams are most heavily used in the bathroom
in the early morning before work or school and possibly at night before bed.
Most members of the family will be present at their time of use. Hair sprays
are applied on a less frequent schedule. Housecleaning is generally performed
a few times per week, in the morning or afternoon. Chores such as cleaning
the oven are done at greater intervals. In any case, the housewife and any
pre-school children would be exposed to aerosol contaminants from household
spray products.
Usage patterns and rates for the aerosol products appearing in
Table 3-4 are presented in Table 3-5. The quantities of materials used are
based on the numbers of various sizes of cans of a product which the householder
reported using. Window cleaners were not listed and were not considered
lurther since we found that a significant portion of their use is likely to be
out-of-doors.
Propellant Emission Estimates
Most spray systems consist of two components: Functional or "active"
ingredients and the propellent. The functional ingredients comprise the cleaning
agents, perfumes, solvents, polishing waxes, disinfectants, etc. Propellants are
used to dispense the functional portion from the container. Although the exact
proportions and ingredients used in aerosol products are proprietary information,
TRC was able to determine the majority of ingredients for the most frequently used

products in Table 3-4 with the exception of dust sprays. Table 3-6 shows the
wide variety of active ingredients that can be packaged in aerosol form.
Because of the diversity of compounds used as ingredients, the lack of any
information about the quantity of each ingredient in a single product and the
amounts of active ingredients actually used versus the amount emitted to the
atmosphere, we did not attempt to quantify the emission of active ingredients
to the indoor atmosphere. It is our judgement the impact of. the active ingre-
dients can only be determined from a well-designed measurement program, which
was beyond the scope of the present study.
There are a number of propellants used as well as shown in Table 3-6.
Of those listed, however, the Freons appear to predominate in use. Isobutane
is used in some window cleaners, propane, methylene chloride and vinyl chloride
are used in a few hair sprays and nitrous oxide is used in some shave creams and
food products. Although we did not develop any conclusive propellant usage data,
we estimate that Freon propellants are used in at least 75 percent of the aerosol
products. For this reason in estimating propellant emissions we have assumed
that the propellants are fluorocarbons.
By focussing on fluorocarbon propellants we are not suggesting this is
the only class of compounds worth examining. Until we can more accurately deter-
mine the amount of active ingredients emitted to the indoor atmosphere and the
usage of propellants other than fluorocarbons, quantitative assessments of their
impact would be speculative.
Emission estimates are a function of the rate of use, frequency of use,
and the proportion of propellant in the spray container. Taking for an example
the information appearing in Table 3-5 for deodorant sprays, and making certain
assumptions, it is possible to compute the approximate quantity of propellant

emitted into the indoor atmosphere during each individual use. If we assume
that the deodorant is used in a household with three occupants, and that each
occupant uses a deodorant product every other day (this is generally consistant
with the inventory data shown in Table 3-5) the number of individual uses each
month will be 45. At 40% propellant, the amount of propellant emitted during
each individual use can be computed as follows :
(112 - 140 g/mo) x .40 (fraction propella.nt) . _ t , 0 ,
*" TT / ec * 1.0 to 1.2 g/use
45 uses/mo
Application of this estimating technique to the other aerosol products
resulted in the emission quantities appearing in Table 3-7.
An experiment conducted at TRC was performed to validate data from the
inventory. Several brands of deodorant were tested to determine the dispensing
rate of aerosol. Analytical measurements gave a range of .3-.9 g/sec. If we
assume an average rate of .6 g/sec, 40% propellants and a typical use of 4 seconds,
the amount of propellant emitted per use would be:
.6 g. x.40x4-1.0g propell ant/use
sec
This result is in excellent agreement with our inventory findings.
We expect that information assembled on less frequently used products would
be somewhat less reliable especially with respect to estimates of usage
rate. Those spray products that are used regularly are likely to be more
closely estimated.
Referring once again to Table 3-7, we note a wide range of propellant
emission rates per household use for the aerosol products listed. Shaving
foams are estimated to emit less than .5 grams of propellent per use, while
a maximum emission of 25 grams/use was determined for oven cleaners. We have
less confidence in the emission estimate for each use of oven cleaners than

for some of the other products, because this material is used only infrequently.
While the contamination of the indoor air relates to these emissions,
the level of contamination will also be influenced by factors such as location
of use, volume space of room, air circulation rate, contaminant half-life,
and the specific design of the residence. Those products which are dispensed
in small, poorly ventilated areas are not likely to disperse readily throughout
the house yet they would be expected to contribute to relatively high initial
concentrations within the room where they are dispensed. Aerosols which are
employed throughout the residence under condition of adequate air circulation
would result in somewhat lower initial room concentrations and decay more
rapidly with time.
The nature and extent of indoor air contamination,,aa was indicated,
is a function of many independent variables. Some limits and the scale of the
problem may be obtained, however, by using the propellant emission data collected
in our inventory and several appropriate assumptions. For the purpose of com-
parison, we will investigate three situations as described below:
(1) Case 1: Deodorant Spray Propellant, 1-2 g/use, dispensed in bathroom.
(2) Case 2: Air Freshener Spray Propellant, 8.4 g/use, dispensed
throughout house
(3) Case 3: Oven Cleaner Propellant, 25 g/use, dispensed in kitchen.
If we assume that a deodorant spray is used in a tightly closed
3
bathroom of 10m volume, we would expect that the initial concentration of
propellant would be:
i - .12 g/m3 - 120,000 yg/m3
- 179 -
-------
Since fluoro carbons are extremely unreactive under ambient conditions,
we would expect the half life of the material based on dispersion and
dilution would be similar to that measured for CO in House No. 2 in Task 2,
or roughly 2 hours. Thus, as long as someone remained in the closed bathroom,
they would be exposed to concentrations at approximately this level.
If we assume that the amounL or propellant from two sequential
uses of aerosol deodorant is dispersed completely throughout a small house of
255 m volume, the initial concentration would be:
K 1() * 940°
Using a half life of two hours, concentrations after 8 hours would
3
be about 600 yg/m .
Air freshener sprays are considered to be applied In most rooms of the
house so that an initial concentration of propellant for the indoor environment
is established quickly and for the most part uniformly.
8'255gm3 = .033 g/m3 = 33,000 yg/m3
With a 2-hour half -life, the average indoor concentration would be
3
2000 yg/m after 8 hours.
Application of spray oven cleaners in the confines of the kitchen
O
(assume a 22m volume) would possibly produce an initial room concentration
of propellant as follows, assuming the kitchen is closed off from the rest of the
house: 7C- 3 3
-Q.&. 3 = 1.14 g/m - 1,140,000 yg/m
22 m
Assuming that contaminants from a single use would be rapidly dispersed
throughout the whole house, the average propellant concentration would be:
=0.10 g/m * 100,000 Pg/m
- 180 -
-------
After eight hours, the indoor concentrations in the house would be
about 6,300 ug/m3.
The Threshold Limit Values (TLV's) set by the American Conference of
Governmental Industrial Hygienists for propellants of the types commonly
3
used are in the approximate range of 5000 to 7000 mg/m . Thus, with the
possible exception of oven cleaner use, none of the individual aerosol product
use in the house appears to approach the TLV for propellant. However,
depending on use patterns and in a given house, (e.g., simultaneous or sequential
use of several products) indoor concentrations of propellants could exceed
these limits on occasion. Furthermore, the active materials dispensed could
add an unknown but probably significant component to indoor air contamination
from these products.
Further research on the specific impact on indoor air quality of
aerosol products and other activities identified above is clearly needed.

-------
CALIBRATION PROCEDURES
FOR THE BENDIX CHEMILUMINESCENT
NO & N02 ANALYZER
GENERAL
1. Allow instrument to warm up as long as possible, but at least
4 hours. Use the mode at all times.
.li.
2. Set up calibration apparatus: Connect in order: 1) pump,
2) UV lamp, 3) scrubber. 4) ozone generator, 5) mixing chamber,
and 6) output manifold. Connect the NO supply in the following
order: 1) NO Cylinder, 2) pressure regulator, 3) capillary,
and 4) valve for bubble flowuieter. The NO and air should join
ahead of the mixing chamber.
3. Set the instrument's three range scales to the 0 to 0.5 ppm
range.
4. Switch the instrument to zero, turn on zero ozone lamp on the
zero air scrubber, and allow at least 10 minutes for stabili-
zation.
5. Adjust the "N02 ZERO" knob until the N0£ pen reads 5% of scale,
then lock the knob.
6. Adjust the "NO ZERO" knob until the NO pen reads 5% of chart.
Lock.
7. Turn the meter switch to "NOx" position and adjust the
"NOX ZERO" knob until the meter reads 5% of scale. Lock.
8. Recheck the zero on the two pen chart recorder and allow 5-10
minutes to check the chart trace on zero.
9. Connect the instrument inlet to the output manifold of the
calibration apparatus. Keep the ozone and NO off, so that zero
air is being provided.
10. Switch the instrument to "AMBIENT" and sample the calibration
zero air. There should be no change in the zero readings. If
there is a change, check the following:
a. If calibration zero air reads higher than instrument
zero, check UV lamp and zero scrubber on calibration
apparatus and replace scrubber material.
b. If calibration zero air reads lower than instrument
zero, check zero scrubber and UV lamp on instrument zero
module and change scrubber material.
- 184 -
-------
II. NO CALIBRATION
1. Turn the 3-way valve to the bubble flowmeter position and turn
on the NO cylinder valve.
2. Adjust air flow and NO pressure to get approximately 0.4 ppm NO.
(A) NO ppm = NO flow rate (cc/min) x N0 Cylinder ppm
NO flow (cc/min) + air flow (cc/min)
3. Measure the NO flow at least twice with the bubble flowmeter.
4. Switch the 3-way valve back to regular flow and allow the
instrument to sample the concentration for at least 10 minutes.
5. Calculate the exact concentration, using (A) above. Extrapolate
desired chart reading using (B) below:
(B) Chart reading (%) = (NO concentration x 200) + 5.
6. Adjust the "NO SPAN" knob until the NO recorder reads correctly,
as determined in step 5 above. Lock the knob.
7. Adjust the "NOX SPAN" knob until the instrument meter reads the
same percent of scale as determined in step 5. Lock the knob.
8. Repeat steps 1-4 to 1-8 to recheck the NO and NOX zero baseline.
If adjustment is necessary, repeat steps II-2 to II-8.
9. Reduce the NO concentration by changing the NO flow. Measure
the NO flow with bubble flowmeter and calculate the concentration
as in II-2(A). Sample and measure at least three other NO
concentrations. Do not change "NO ZERO" or "NO SPAN" settings.
10. Plot the 5 or more chart readings versus the NO concentration
in ppm. Draw calibration curve or obtain computer printout of
net chart divisions versus the NO concentration in ppm.
III. N02 CALIBRATION
1. Adjust the NO concentration to about 0,45 ppm. Measure the
NO flow rate and calculate the exact NO concentration, using
formula (A) from II-2 above.
2. Allow the instrument to sample the concentration. Switch the
meter to NOX and observe and record the meter reading. Turn on
the ozone generator and adjust the slide such that the 03 output
is sufficient to oxidize about 90% of the NO present to N02.
If the NOX value drops more than .015 ppm (3% chart) the analyzer
converter needs to be replaced.
- 185 -
-------
3. Wait 10 minutes until the NO recorder reading is stable, then
calculate the N02 concentration as follows:
(C) N02 (ppm) = NOX (ppm) - NO (ppra)
where:NOX is the original NO concentration from III-l.
NO conc^._ ___^n is the reading on the NO recorder,
converted to ppm by the calibration curve prepared
in II-9.
4. Now calculate the desired N0£ chart reading :
N02 chart reading (%) - (N02 concentration x 200) + 5.
5. Adjust the "N02 SPAN" knob until the N02 recorder reads correctly
as determined in III-4. Lock the knob.
6. Turn off the ozone lamp on the zero air scrubber and reconnect
analyzer to sampling system.

16. ABSTRACT
A study of indoor air quality was carried out over a 15-month
period by TRC - The Research Corporation of New England. The program
consisted of three tasks:
1. Laboratory investigations
2. Field studies
3. Inventory of indoor sources
Tasks 1 and 2 established the emissions and effect on air quality
(N02, NO, and CO) of gas stoves and heaters both in the laboratory and in
4 homes with gas-fired stoves in the Hartford, Connecticut area.
Task 3 developed information on indoor sources of air contamination
in typical southern New England homes and provided the basis for assessing
the impact of aerosol products and their use on indoor air quality.
