MISSION
OF
CHEMISTRY AND PHYSICS
LABORATORY

-------
Chemistry and Physics Laboratory's Mission
NERC/RTP's Chemistry and Physics Laboratory manages and conducts an
intramural and extramural research program which provides: techniques and
instrumentation for the measurement of atmospheric pollutants, information
on the chemical and physical transformations that pollutants undergo in the
atmosphere, and information on the effects of atmospheric pollutants on
materials. While each of these program areas contributes directly to the
air pollution control program, they are also closely interrelated: air
pollution measurement techniques and instrumentation research supports
atmospheric chemistry and physics studies; atmospheric chemistry and physics
studies provide information on what measurement techniques are needed; and
studies of the effects of atmospheric pollutants on materials provide infor-
mation on mechanisms whereby pollutants can be removed from the atmosphere.
The program of the Chemistry and Physics Laboratory is totally responsive
to the legislative mandates of the Air Quality Act of 1970.
Each year the Chemistry and Physics Laboratory conducts one or more
field studies of air pollution. During 1973 a field study was conducted in
Denver, Colorado, in cooperation with the EPA Regional Office and the State
air pollution control agency. The study was part of a continuing effort to
determine the nature and source of the Denver "Brown Cloud." Field studies
were also conducted in Houston, Texas, and Phoenix, Arizona, on photochemical
oxidant and in St. Louis, Missouri, on photochemical oxidant and on sulfur
oxides air pollution.

-------
Analysis of the data for the Denver field study indicates that the
"Brown Cloud" is a two-component plume: one part, close to the ground,
which contains major amounts of aerosol from stationary sources and a second
part above the first which contains aerosol largely from automotive sources.
The Chemistry and Physics Laboratory provides administrative manage-
ment of the Air Pollution Chemistry and Physics Advisory Committee. The
Committee met twice in 1973: first in St. Louis, where the principal agenda
item was the Regional Air Pollution Study (RAPS) in progress there; and
second at the University of Minnesota, where the main subject was atmospheric
aerosols.
Research on the effect of air pollutants on materials and on atmospheric
visibility is part of the program of the Chemistry and Physics Laboratory.
In 1973 an experiment was begun in which several critical materials were
exposed to simulated polluted atmospheres in chambers. The first phase of
this work will be completed in 1974 and will eventually provide quantitative
dose/response information.
In 1973 the Chemistry and Physics Laboratory developed specialized
gas chromatographic instrumentation to measure "reactive hydrocarbons in
automotive exhaust. This equipment was put into use in EPA's Mobile Source
Pollution Control Laboratory in Ann Arbor, Michigan. Also in 1973, work
was started on additional engine dynamometers and a stationary source simu-
lator to increase the facilities which support research to develop instru-
mentation and techniques to measure pollutants emitted by these sources.

CPL initiated a program cm analytical methods and instruments to be
used as portable analyzers (dosimeters) in health studies to aid in revision
of air quality criteria. Effects of air pollutants on organic and inorganic
materials are investigated in environmental chambers to supply inputs to
development or modification of secondary standards for the criteria pollu-
tants. Research on new particulate mass monitoring instrumentation is in
progress to provide a more acceptable reference or equivalent method for
total suspended particulates. Considerable effort is going into the
development of the measurement technology for fine particles and for other
pollutants which may be considered candidates for air quality criteria.
The formation and decay of such non-criteria pollutants also is under
investigation.
Considerable efforts in support of present national ambient air quality
standards (particularly those for hydrocarbon/oxidants and nitrogen dioxide)
are in progress in CPL to further verify the atmospheric relationships
involving hydrocarbons and oxidants. Evaluation of the reference method
for nitrogen dioxide was made and improved for the 24-hour average colori-
metric methods and continuous instrumentation developed.
The CPL is involved in a considerable effort to support development
of chemical and physical air pollution models for reactive pollutants for
use in implementation plans, including site criteria of large area sources.
The transport of oxidants and the rural oxidant problem are under investi-
gation Empirical relations between hydrocarbons and oxidants (such as
upper limit curves) and relationships between hydrocarbons and nitrogen
dioxide are being reviewed and evaluated. Reactivities of hydrocarbons
and other organics have been evaluated for organic solvent regulations and
transportation plans.
Measurement technology is being developed and evaluated for regulated
and non-regulated emissions from on-the-road vehicles and advanced power
sources. Improved optical measurement instrumentation has been developed
for the regulated pollutants. Measurements proceed to support a reactivity
type hydrocarbon standard if undertaken. Extensive research has been done
on sampling techniques for particulate emission from light-duty vehicles
operated on leaded and non-leaded fuels using test vehicles with and without
catalytic devices.
Extensive support is provided by CPL in verifying and improving the
reference methods for Category I and II new source performance standards.
Performance criteria have been developed for extractive and in-situ lnst™~
mentation for determination of compliance with sulfur oxide, nitrogen oxid ,
and opacity standards for a number of the Category I sources. Methods
development continues on the reference methods required for Category III,
IV, and V new source performance standards.
- CPL is responsible for developing the analytical methodology for the
national emission standards for hazardous pollutants.	'
sampling and analysis are under investigation or evaluation for asbestos
and mercury. There has been extensive development of
methods for use in analyzing a number of elements possibly of a hazardous
nature. Improved sampling and more rapid analysis methods for polycyclic
organic matter are under development.

CPL provides support in development of emission protocols for fuel
additives effects. The CPL also does the emission characterization of
non-regulated emissions from vehicles equipped with catalytic devices and
on non-regulated emissions from advanced alternate power systems. In 1973
considerable work was done on the problem of sulfate formation by exhaust
oxidation catalyst systems. Work was begun on alternate automotive power
systems such as the Wankel engine and the passenger vehicle diesel engine.
Technical support is provided by CPL in development of air quality
criteria documents and on progress reports required by Congress on air
quality and emission instrumentation and on emission standards for moving
vehicles.
ORGANIZATION
The Chemistry and Physics Laboratory is organized into three branches.
One of these deals with the problems of the physical and chemical transfor-
mations of pollutants in the atmosphere and the other two are concerned
with the development of techniques and instrumentation for the measurement
of air pollution. All three branches are involved in both laboratory and
field research and implement their programs through in-house projects and
extramural research grants and contracts.
Atmospheric Chemistry and Physics Branch
The Atmospheric Chemistry and Physics Branch performs both laboratory
and field studies. Laboratory studies are conducted in clean glass chambers
using pure components and in large irradiation chambers using real components
11

-------
such as motor vehicle exhaust. Hypotheses developed In these laboratory
studies are tested in the field by analysis of the atmosphere at critical
sites chosen on the basis of the pollution sources and the meteorology and
topography of the area. All of this information is used to choose appropriate
air pollution control strategies. It also is used to develop mathematical
models of atmospheric photochemical reactions. Although the atmospheric
chemistry and physics program previously concentrated on atmospheric reactions
of gaseous pollutants such as are involved in the formation of ozone, it now
also includes studies of atmospheric reactions involving aerosols. The
Branch also conducts research to determine the effects of environmental pol-
lutants on materials. These capabilities in atmospheric chemistry are used
in the Laboratory's participation in the Regional Air Pollution Study (RAPS)
and in the Fuel and Fuel Additive Registration Program.

tivities to provide analytical techniques and instruments for the
ment act	precise measurement of environmental pollutants in emissions

discharge	carried out primarily to support the implementation of national
12

-------
emission standards for mobile sources, new stationary source emission standards,
and national emission standards for hazardous air pollutants as required
under the provisions of the Clean Air Act of 1970. This Branch also conducts
studies for the chemical and physical characterization of pollutants emitted
from various sources.
PHYSICAL FACILITIES
A research prototype lidar system, designed specifically for particulate
emission measurements from stationary sources, is housed in a mobile van
to facilitate field studies now in progress.
Other research prototype systems include two research infrared spectro-
photometers for the remote sensing of emissions from stationary sources.
These instruments are also capable of long-path measurement of extended
source emissions. The Bendix spectrophotometer is presently computer-programmed
to monitor ozone in the atmosphere. The Convair spectrophotometer has scan-
ning capability in the 3 tj 5 and 7 to 14 micron wavelength range and much
higher resolution (1.0 cm ) than the Bendix (10 cm ).
An experimental stationary source simulator is installed in a leased
facility at the Beaunit Corporation Technical Center in the Research Triangle
Park. This facility is used to generate test flue gases with particulate
matter, moisture, and pollutants under defined conditions, conditions that
must be known so that sampling and analysis methods can be evaluated under
controlled experimental situations before actual field testing is undertaken.

This equipment provides a 2 x 3 x 35 foot test section and up to 450°F (233°C)
flue gas temperature and 80 ft/sec (24 m/sec) flow velocities to simulate
conditions encountered in typical power plant operations. Both extractive
and cross-stack optical instruments are tested at this facility before actual
installation or field testing at combustion sources.
The electron optical facilities include scanning electron microscopy
(SEM), transmission electron microscopy (TEM), and X-ray diffraction equip-
ment . The SEM, used for morphological studies of stationary and mobile source
particulate emissions, is equipped with two X-ray spectrometers giving it a
capability for quantitative and qualitative chemical analysis as well. The
wavelength X-ray spectrometer allows conversion of the SEM to an electron
microprobe for quantitative chemical analysis of particles of less than 1
micron in diameter. The energy dispersive X-ray spectrometer allows quali-
tative chemical analysis, for elements beyond sodium, of particles only a
few hundred angstroms in diameter. The TEM is used for examination of
particles less than 0.1 micron in diameter where crystal structure is an
important consideration. Electron diffraction techniques afford a means of
identifying the compound species of the particles being examined. X-ray
diffraction is used for identification of crystalline material or mixtures.
Quantitative analysis is possible from observation of intensities of X-ray
maxima as a function of percentage composition of a crystalline phase. The
mobile source emissions laboratory is used for the observation and delineation
of the emissions of mobile sources, their characterization and quantification,
and the development of the most precise techniques for their analysis. The
wide range of analytical capability includes particulate and gaseous com-
ponents such as sulfates, fuel additive components, and other non-regulated
emissions. This general capability is provided by analytical facilities

which include:
(a)	An Hitachi RMU-6L mass spectrometer coupled to a Perkin-Elmer 990
gas chromatograph. The mass spectrometer accurately measures the
atomic mass of molecules presented to it while the gas chromato-
graph provides fractionation by the principle of absorption.
The mass spectrometer can also analyze gaseous and liquid samples
providing unique information on the molecular weights of the chemical
species present.
(b)	Gas chromatography capability for separating and analyzing auto-
motive exhaust in its individual components. This typically results
in over 100 hydrocarbons and many substituted organic components,
and is being expanded to higher molecular weight components. The
principles involve selective absorption, elution, and detection
using flame ionization detectors which respond with extreme sensi-
tivity to individual carbon atoms. Typical sensitivities are about
0.01 ppm. Special techniques allow these limits to be extended
approximately an order of magnitude.
(c)	Other general analytical equipment including NMR (Varian T60),
infrared spectrophotometer (P-E 180), UV-visible spectrophotometers
(Cary Model 14 and Beckman Model B) , chemiluminescent equipment,
atomic absorption, microbalances, liquid chromatographs, and other
modern analytical laboratory instruments.

The mobile source testing facility is installed at Beaunit's Technical
Center in Research Triangle Park. Installed equipment includes a water brake
certification dynamometer complete with a constant-volume sampler and a
particulate sampling tunnel. Also available for installation are two engine
dynamometers for light-duty engines and one engine dynamometer for heavy-
duty engines. Dilution tunnel and constant-volume samplers are available
to allow the measurement of gaseous and particulate emissions. This equip-
ment allows vehicles and engines to be operated under conditions which
simulate those encountered by the general population.
These facilities allow the operation of vehicles and engines to permit
evaluation of control devices (such as catalysts) and the characterization
(see above) of non-regulated emissions due to unusual operating conditions
or the use of other fuel components - either fuel additives or unusual fuels.
The analysis of air for pollutants by long-path infrared spectroscopy was
used by the early workers in the field of air pollution to detect ozone as
a constituent of smog. A new system, capable of detecting fractional parts
per billion (by volume) pollutant concentrations, is operated by CPL personnel.
This new long-path irradiation chamber has a basic length of approximately
30 feet: mirrors on each end provide an optical path of over 3000 feet.
When the effective path length of air is analyzed with a Fourier Transform
Infrared Spectrometer and a computer for nearly instantaneous data analysis,
pollutants at concentrations of a fraction of a part per billion (by volume)
can be identified and measured. The system is now used to detect pollutants
that have not been measured or that have been measured only with difficulty,
both in the laboratory and field.
Several mobile laboratories are used for field studies of atmospheric
chemistry and physics. These laboratories are equipped with gas chromato-
graphs and ozone, sulfur dioxide, and N0x analyzers. Aerosol sampling and
sizing equipment is available, as well as meteorological weather monitoring
equipment.
Two smog chambers, soon to be operational, will permit simulation of
polluted atmospheres for study of aerosol formation and growth and hydro-
carbon/nitrogen-oxide/oxidant reactions. Five chambers are in use for
simulating polluted atmospheres to study the effect of such atmospheres on
critical materials.
MAJOR PROGRAM AREAS
Principal efforts of personnel of the Chemistry and Physics Laboratory
are aimed in two directionsi studies of the physical and chemical transfor-
mation of atmospheric pollutants, and development of techniques and instru-
mentation for measuring air pollution.
Among ongoing studies in the area of pollutant transformation are those
on: formation and removal of noxious gases in the atmosphere; effects of
aerosol composition on visibility; oxldant/precursor relationships for control
strategies; the Regional Air Pollution Study (RAPS), relating to air quality
characterization; the character and origin of aerosols; and effects of air
pollutants on organic and inorganic materials.
16

-------
Work relating to air pollution measurement includes: new and improved
methods for measuring and analyzing ambient air particulates; personal
exposure dosimeters; fine particulate methodology; the RAPS; gaseous pollutants
in ambient air; mobile source emissions; gaseous pollutants emitted from
stationary sources; criteria for selection of stationary source measurement
strategies or methodology and instrumentation; and particulates and
hazardous substances emitted from stationary sources.
Formation and Removal of Noxious Gases in the Atmosphere. Transformations of
sulfur oxides, nitrogen oxides, and organic pollutants are being identified
and described quantitatively. Gas- and condensed-phase processes are both
under investigation. Reactivities and reaction paths are being established.
Intermediate chemical species as well as final oxidation products are being
identified and measured. Real atmospheres are studied at selected locations
using mobile equipment. Simulated polluted atmospheres are studied under
controlled conditions in the laboratory. Results, being fit into chemical
mechanisms, are yielding parameters for the mathematical modeling of the
atmospheric transformation processes. The results are disseminated in reports
on the chemical and physical processes involved in the formation, transport,
and removal of toxic and noxious substances in the atmosphere. Technical
papers are published which provide insights into the self-cleansing properties
of the atmosphere. Rate and mechanism data are provided for the mathematical
modeling of the reactions in the polluted air. Relationships between pol-
lutant emissions and adverse effects are described. Advice is given as to
control strategies for minimizing the formation of noxious gases in the
atmosphere. Nearly all of the nine atmospheric noxious gas tasks described
below are multi-year projects which will be continued. As solutions are
developed for the problems being studied, emphasis will be shifted to unsolved
problems in the same research area.
Field Studies of Gaseous Pollutants. The objectives of these studies are
to characterize the St. Louis and Houston atmospheres. Our interest includes
compositional differences as well as similarities of air samples as a function
of time of day and sample site location. Of principal interest is the hydro-
carbon distribution, oxides of nitrogen concentration, and oxidant production
in these two cities. Future work of this type will involve vinyl chloride
and other halogenated pollutants in Houston, and oxidant transport in the
Ohio/Indiana area.
In-situ Pollutant Identification by Spectroscopy. FTS infrared spectroscopy
methods are used for in-situ identification of products from atmospheric
photooxidation of hydrocarbons. Mirrors have been installed in the interior
of a smog chamber and serve as part of the optical system of an FTS
spectrometer. Observations are made upon photoirradiated mixtures of HC
and NO at ppm-levels and the analytical effort is focused on species that
cannot^e measured by analytical techniques that require sample-handling.
Such evidence assists the development of mathematical models of photochemical
smog and allows assessment of the role of the various primary pollutants
in the smog forming process. Topics of interest include: mechanism of the
ozonolysis of olefins, role of H20 in photochemical reactions, the photo-
oxidation of aldehydes and fate of the carbon in aromatic~NO systems.
Future work will include the photolysis of alkyl nitrites.
17

-------
Oas-Phase Ozonolysis. The object of this continuing research grant is to
resolve the discrepancies in the reported values of the second order rate
constants for olefins/ozone reactions. The effect of decreasing the reac-
tant concentrations is being investigated and the product yield studied.
These studies should produce a detailed mechanism for ozone/olefin reaction
in the gas phase.
Oxidation and Removal of Gaseous Pollutants. The objective of this continuing
research grant is to understand the primary process in the photochemistry
of SO and to measure the reactivity of other pollutants in systems of atmos-
pheric interest. Rate constants have been measured for R-C03 + SO and
RO + SO reactions. Future studies will concentrate on understanding S02
oxidation in the atmosphere and on understanding free radical reactions in
general.
Los Angeles Reactive Pollutant Study. This study is a cooperative program
with the Coordinating Research Council, now in its data analysis and reporting
phase: it may be concluded next year. An attempt is being made to develop
a model of a reacting, moving parcel of polluted air in the Los Angeles area.
Measurements were made on such pollutants as NO, N0£, 0^, CO, and hydrocarbons.
Samplers were both airborne and groundbased. Air movements were tracked
with tetroons and radar.
Halogenated Compounds in the Atmosphere. This research grant task at Rutgers
University is concerned with the measurement, tropospheric reactions and
lifetimes of Freons. In the past several years, the use of fluorinated
hydrocarbons has increased considerably. Lovelock's tropospheric measure-
ments show that Freon 11 and 12 are increasing almost proportionately to
the emission rates. This work will look into possible removal processes
for the Freons. If no removal processes occur, then recommendations will
probably have to be made on the wisdom of the buildup of non-reactive halo-
carbons in the atmosphere. Work during the coming year will be expanded
to. allow increased field measurements, using a mobile laboratory.
Chemistry of Nitrogen Compounds in Air. Comparisons of atmospheric data
show emissions of nitrogen oxides (NO ) to be greater than the observed
nitrate and NO aerometric concentrations. Also, atmospheric modelers have
arbitrarily reduced NO in order to obtain satisfactory models of Los
Angeles' type smog. l£ is apparent that a problem exists either in the
manner in which NO is measured or that large unknown sinks are removing
NO from the atmosphere. In the coming year, field measurements will be
maSe in two cities, using groundbased and airborne sensors.
Photochemical Model Development. The objective of this work to be continued
through intramural and contract effort, is to develop a kinetic mechanism
describing photochemical smog formation that can be incorporated into
diffusion models to assess air quality. The mechanism developed will be
tested against smog chamber data obtained for the Regional Air Pollution
Study. Additional studies are underway to determine rate constants (for
use in these models) for some reactions of importance in smog formation.
Experimental Studies of Control Strategies. The task now in the stage of
analysis, and reporting of the first year's data, calls for continuation of
smog chamber tests of hydrocarbon (HO/NO^ mixtures to determine the effect
18

-------
of the reactant HC concentration on concentration of the N0„ product.
Reactant mixtures are similar to those encountered in a typical urban at-
mosphere and are irradiated in a dual-compartment 14,000 cu. ft. outdoor
smog chamber. Effects of HC are determined in the experiment by using a
differential design such that the reactant mixtures in the two chamber
compartments differ only in HC concentration. Resultant evidence provides
a first-approximation estimate of the effect of hydrocarbon control on
ambient NOData taking will continue in the coming year.
Effects of Aerosol Composition on Visibility. Visibility reduction is the
most obvious effect of atmospheric pollution, but ironically it is not well
understood. It is recognized that visibility is spoiled by light scattering
from aerosol particles, but the physics of the scattering phenomenon and
the chemistry of the formation and growth of the scattering particles have
not been adequately explained. In order to bring visibility loss under
control, further scientific study of its causes is required.
Optical properties of primary and secondary aerosols are being measured;
the relationships between the physics of the scattering phenomenon and the
chemistry of the formation and growth of the scattering particles have not
been adequately explained. In order to bring visibility loss under control,
further scientific study of its causes is required.
Optical properties of primary and secondary aerosols are being measured;
the relationships between the physical and chemical properties of the aerosols
and the scattering and absorption are being outlined; water evaporation
and condensation within aerosols are being measured; Mie scattering is being
calculated and measured; quantitative data are being developed on the con-
version of NO and SO to particulate nitrate and sulfate,
x	x
The output of the program will include: optical properties of primary
and secondary aerosols; relationships between visibility loss and aerosol
characteristics such as size, shape, and chemical composition; effects of
relative humidity on aerosol properties; scientific data for visibility
criteria and standards; and data from which to derive pollution control
strategies which will improve atmospheric visibility.
Determination of Oxidant/Precursor Relationships for Control Strategies.
Oxidants are legally controlled pollutants, but they are not emitted directly
to the atmosphere. An oxidant is formed in the air by photochemical reactions
involving nitrogen oxides, oxygen, and hydrocarbons. The word oxidant desig-
nates material which causes an oxidation reaction in certain test procedures.
It generally consists of about 90 percent ozone and 10 percent peroxy acyl
nitrates.
Control of oxidants follows from control of their precursors - nitrogen
oxides and hydrocarbons. Permissible limits of the precursor concentrations
must therefore be based on knowledge of the photochemical processes in the
air. The oxidant/precursor relationships must be determined in quantitative
detail.
The problem is studied in laboratory simulations which yield precise
but indirect determination of the oxidant/precursor relationships. Field
studies are also being carried out for approximate but direct determination
19

-------
q£ the relationships. From the results of all the studies, empirical rela—
tionships among the chemical variables are derived.
The output will be reports presenting the quantitative relationships
between the oxidants and the oxidant precursors under various ambient
conditions. Such information is to serve as scientific basis for
recommending regulatory actions concerned with improvement of the oxidant
related air quality.
Several projects were initiated in 1973 to further define these rela-
tionships. Smog chamber tests are being conducted on hydrocarbon/NOx mixtures
similar to those encountered in typical urban atmospheres. Also, testing
will be conducted under conditions similar to those that prevail in oxidant/
transport phenomena; namely, prolonged and repeated irradiations. Results
will be used to compare the oxidant/HC/NO relationships with those observed
under non-transport conditions. Such evidence will serve to more defini-
tively assess the importance of oxidant transport phenomena and to provide
bases for inclusion of transport considerations in the design of oxidant
abatement strategies.
The task, effect of emission control on oxidant/hydrocarbon relation-
ships, calls for smog chamber testing of HC/NOx mixtures similar to those in
the exhaust from current automobiles and from automobiles equipped with
control devices capable of meeting the 1975 and 1976 emission standards.
Results will be analyzed to provide a first estimate of the effect that
the control-induced change in HC composition would have on the oxidant/HC
relationship. Such information will serve to improve the accuracy of the
oxidant/precursor relationships that are used as the basis of the control
strategy for oxidant abatement.
In the study of aerosol formation as a function of reactant concentra-
tion, smog chamber tests were directed to the study of aerosol formation as
a function of controllable aerosol precursors. Results will be used in
attempts to develop an empirical model relating aerosol mass load (and its
carbon, sulfur, and nitrogen components) to the concentrations of the HC,
NO , and SO- reactants. Such information will contribute toward an infor-
mation base needed to develop a control strategy for aerosol pollution
abatement.
During the study of oxidants as a function of HC, NO , light intensity
and other factors, smog chamber tests are to be conducted on HC/NO mixtures
similar to those encountered in typical urban atmospheres. Tests will
generate evidence on: the oxidant/HC/NO^ relationships under extremely low
reactant concentration conditions; the degree of linearity of the oxidant/HC
relationship at optimum HC-to-NO ratios; the appropriateness of the labora-
tory radiation systems as substitutes for natural sunlight; and oxidant-
yield reactivities of selected organics. Resulting evidence will strengthen
the validity of or improve the oxidant/precursor relationships that are
used as the basis of current oxidant abatement strategy.
The Laboratory's work on analyzing atmospheric gaseous pollution measure
ments calls for analysis of existing atmospheric data to quantitatively
relate afternoon concentration of oxidant - measured directly - to early
morning concentrations of HC and NO^ - surmised from the detailed analysis
20

-------
of the afternoon air samples. It also calls for analyses of polluted air
to improve research methodology. Resulting evidence will ultimately determine
the relationships between oxidants, HC, and NO in ambient air directly
and hence, will provide bases for checking the validity of the oxidant/HC/
NO^ relationships obtained indirectly.
Experimental studies of the effect of HC control on ambient NC>2 involves
continuation of smog chamber tests of hydrocarbon/NO mixtures to determine
the effect of the reactant hydrocarbon concentrationXon the concentration of
the NC>2 product. Reactant mixtures will be similar to those encountered in
a typical urban atmosphere and will be irradiated in a dual-compartment
14,000 cu. ft. outdoor smog chamber. The effect of HC will be determined
in the experiment by using a differential design such that the reactant
mixtures in the two-chamber compartments will differ only in HC concentration.
Resultant evidence will serve to provide a first-approximation estimate of
the effect of hydrocarbon control on ambient NO^.
Regional Air Pollution Study (RAPS): Air Quality Characterization. The
monitoring network of the RAPS will measure gaseous pollutant concentrations
and meteorological variables for use in modeling the transport of the pol-
lutants in the urban air mass. However, the network will have little impact
on describing and modeling the transformations of the pollutants, especially
aerosol formation and growth. It has therefore been necessary to establish
this subprogram which addresses atmospheric chemistry problems.
A team of experienced aerosol scientists was assembled in St. Louis in
the Summer of 1973 to conduct an intensive aerosol characterization program.
Previous experience with the California aerosol was the basis for the de-
velopment of the aerosol study. Special EPA mobile facilities for aerosol
characterization were used. The results of the study are currently being
analyzed and developed for publication. Two gaseous pollutant transformation
projects have been under way: the first is the study of the transformations
of NO and SO in power plant plumes; and the second is laboratory veri-
fication of tfte kinetic models which are to be applied to the network data.
The program output includes: identification of sources of visibility
loss In St. Louis; specifications of particle sizes, size spectra, and
chemical composition; fine particle spatial distribution; identification
of gas/particle interactions for development of visibility reduction models;
data on choice of tracer substances for study of regional atmospheres; and
chemical inputs to the photochemical modeling effort. This work area
involves several tasks.
Aerosol Size Distribution. The basic objective of this research has been:
to modernize, extend, further develop, and utilize an already existing
capability for the measurement of atmospheric aerosols; to apply this
capability in the field, in collaboration with other investigators; and
to increase the Laboratory's analysis, interpretation, and publication
efforts using existing data. The specific objectives for 1973 and 1974
are: to assist EPA in outfitting and operating EPA's mobile field labora-
tory in St. Louis in August and September 1973; to begin development of
a mobile laboratory (with gas, particle, and meteorological monitoring
equipment and a minicomputer-based data acquisition and instrument control
system) for use in St. Louis in 1975; to increase the level of data
21

-------
analysis and interpretation work on available data, using new data
presentation, and analysis forms and concepts; and participate in field
studies and data analysis for the RAPS in St. Louis.
Aerosol Chemical Composition. Application of a computer-controlled high-
resolution mass spectrometer to the determination of the molecular compo-
sition of atmospheric aerosols has been refined and extended. A system for
sampling, compatible with mass spectrometers, has been developed. Computer
control, data acquisition, and reduction (including software) have been
developed. Work to date has proven the capability of the entire system for
the simultaneous determination of up to 100 aerosol components, both
inorganic and organic. The system is being applied to the measurement of
the composition of aerosols collected in the St. Louis Program.
Visibility Degradation Model. Laboratory and field studies are developing
empirical relationships and physical models to calculate visibility as a
function of aerosol mass concentration, chemical composition, size distri-
bution, optical properties, and relative humidity. Field studies and model
development are concentrating on the St. Louis area.
Kinetic Model Verification. Smog chamber studies in the new Riverside
chamber facility are being conducted for the purpose of gathering accurate
and detailed data to aid in the development of photochemical models.
Detailed studies of simple olefin, aromatic, and paraffin systems are
being carried out; the effects of H^O, CO, and aldehydes on the rate of
oxidation of NO are also under investigation.

measured on plumes of St. Louis power plants. Physical dilution of effluent
will be determined with SF^ as a tracer. Air samples will be collected
by airplane and returned to Brookhaven National Laboratories for analysis.
Isotope ratios will be studied. Conversion mechanisms and rates will be
supplied to the developers of the overall St. Louis airshed model. To
date the effort has concentrated on laboratory preparation and method
development.
Aerosol Spatial Distribution. The objective of this work is to conduct a
systematic ambient, laboratory and numerical study of urban aerosol dynamics;
i.e., on the spatio-temporal variation of important aerosol parameters such
as respirable fraction, and light scattering. The present study, designed
from the point of view of an urban air pollution system, is intended to be
an integral part of the St. Louis RAPS. Specific objectives of this research
for the first year were: to characterize spatial distribution of the ambient
atmospheric aerosol in St. Louis in terms of its physical properties, size
and mass distribution (using electrical mobility analyzer, high-resolution
optical counter, and impactor), volatility (aerosol heater), and morphology
(electron microscopy); to obtain aerosol samples for chemical analysis by
other participants in RAPS; and to provide logistical and facility support
to the activities of EPA and other investigators participating in the
St. Louis project.

Air Pollutant Effects on Organic and Inorganic Materials. The interaction
of gaseous and particulate pollutants with material surfaces is of vital
interest from two points of view: the damage inflicted on man-made materials
by acidic vapors, soot, and other airborne matter is of concern; and the
uptake of pollutants by the surfaces is a major removal path and must be
understood quantitatively for development of atmospheric models and control
plans.
23

-------
Statistically designed laboratory controlled environment experiments
are being used to establish cause/effect relationships between pollutants
and materials. Laboratory experiments with SO^, N02> and 0 are being
carried out on an intramural basis. The results of these studies will
include reports and documents on the direct and synergistic effects of air
pollutants on nine classes of sensitive economically important materials.
Final reports will contain dose/response data, at pollution levels below
primary standards, that may be used to set secondary air quality standards.
Quantitative data will be generated on the rates of uptake of individual
pollutants by surfaces of various types.
In the materials damage survey, an evolved two-level fractional factorial
experiment has been conducted using controlled environment chambers, to
screen and assess the damaging effects, both direct and synergistic, of
SO , NO , 0- and climatic parameters on steel, galvanizing aluminum, tires,
paints,Aplastics, fabrics and dyes, marble, and concrete.
Based on the results of this experiment, a more definitive orthogonal
square controlled environment experiment will be designed and conducted
during the coming year to produce dose/response relationships for materials
found to be sensitive to air pollution, both directly and synergistically.
Two additional programs will be undertaken in 1974. The first will
be a multi-year field study of pollutant effects on materials, to be
conducted in St. Louis with the assistance of Rockwell personnel who are
contractors for the RAPS. Materials will be exposed at selected locations
and examined periodically for damage. An effort will be made to correlate
observed damage with measured pollution levels. The second new undertaking
will be a laboratory investigation of the up-take of pollutants by various
types of materials.
Character and Origin of Aerosols. Physical and chemical properties of source,
ambient, and natural aerosols are being determined. Aerosol generation rates
for various sources are being established. The major sinks for aerosol
pollutants are being identified and the removal rates established. The
effects of the aerosols on gas-phase atmospheric chemical reactions are
under investigation, along with the gas/particle conversions and the par-
ticle removal processes. The results of the research are being used: to
establish the contribution of the various sources to the ambient atmospheric
aerosol loading; to characterize urban, natural, primary source, and
secondary source aerosols; to develop quantitative descriptions of generation
and removal rates associated with each major aerosol source and sink, and to
quantify aerosol effects on atmospheric chemical reactions. The scientific
data are basic to the promulgation of fine particle criteria and standards
and to the development of effective control procedures.
Relating Fine Particle Aerosols to Sources. The pollution aerosol is a
dynamic system whose physical and chemical characteristics depend in a com-
plex way on the background aerosol and on particle and gas emissions. The
goal of this research is to develop experimental and theoretical methods
for relating the properties of the pollution aerosol to the characteristics
of emission sources. This is being accomplished by: starting from the
observed characteristics of the pollution aerosol and formulating a set
of hypotheses relating the aerosol to the sources of particles and gases;
24

-------
carrying out laboratory experiments and theoretical calculations aimed at
testing these mechanisms; and arriving, at a tested quantitative understanding
of the origins of the smog aerosol. Experimental studies include investi-
gations of the conversion of organic gases and SO^ to particulate matter
in an ozone-rich atmosphere.
Aerosol Optical Characteristics. The objective of this work is to
chemically analyze aerosol particles while still in the dispersed state,
thus avoiding errors due to compositional changes during collection.
Measurement of optical properties such as infrared absorption seems to be
the most promising route. Initial studies are devoted to the feasibility
of candidate techniques, especially the Laser Absorption Spectrophone
method.
Aerosol Modeling. A variety of aerosol submodels are under development.
Chemical and physical aspects of aerosol formation growth, and removal
are being integrated into a larger model. The models are being applied
to field and laboratory data.
Theoretical Studies of Aerosol Physics. This research grant is devoted to
theoretical development of aerosol dynamics to provide practical models
that describe the growth of aerosol particles in the atmosphere, the
evaluation of size distributions, and applications in air cleaning and
health.
Chamber Research on Aerosol Formation. A 20,800 cu. ft. chamber at Calspan
and smaller chambers at the University of Minnesota have been used to
produce aerosols photochemically from mixtures of hydrocarbons and NO with
and without SO2. Aerosol particle growth has been investigated as a func-
tion of reactant concentrations, relative humidity, and temperature.
Experiments will also be conducted to study the influence of surface-to-
volume effects, surface contaminants, and stirring on aerosol formation
and growth.
Aerosol Formation from Naturally Emitted Hydrocarbons. Research focuses on
the conversion of terpene-type hydrocarbons to aerosol particles with
emphasis on quantitative and qualitative analysis of the organic content
of the latter. Such information will serve to assess the contribution of
naturally emitted hydrocarbons to air pollution.
Organic Analysis of Atmospheric and Laboratory Aerosols. Model aerosols
are generated from selected individual hydrocarbons representative of those
emitted to the atmosphere from natural and technological sources. The
organic fraction of the aerosols is being characterized in detail. The
effects of various simulated atmospheres on yields and type of products
generated from different hydrocarbons (aromatics, olefins, paraffins, and
terpenes) and their contribution to aerosol formation are being investigated.
Experimental Laboratory Studies of Aerosol Dynamics. This program will
obtain the experimental data needed to develop chemical, physical, and
mathematical models of atmospheric aerosol formation and growth. The pro-
gram emphasizes studies of elementary chemical and physical processes and
includes simulation of photochemical processes. Aerosol formation processes
being studied include those which produce complex organic mixtures. Physical
25

-------
Smog CkambeA Studio oh ktmobphdrvLc PhotockmlitAc/
processes being studied include nucleation of the reaction products and
growth by condensation and coagulation. Parameters to be varied include
number, size, distribution, and chemical composition of pre-existing nuclei,
relative humidity, and temperature. The data will be made available for
analysis and modeling by other organizations as requested by EPA.
Elemental Analysis and Source Identification for Aerosols. The transport
of heavy metals and other elements in aerosols is being investigated in
St. Louis by sample collection of filters and cascade impactors, chemical
analysis by neutron activation and X-ray fluorescence, and correlation with
several variables. The relative importance of natural terrestrial and
marine sources and urban or industrial pollution sources is determined for
each element, as well as the effect of source processes on particle size
distribution. The study should improve EPA's prediction capability for:
the distance of transport of different elements, its dependence on particle
size and meteorological factors, and a determination of the extent of impact
of pollution sources on air quality at distances remote from the sources.
Aerosol Formation in a Flowing Reactor Tube. The formation mechanism and
composition of photochemical aerosols which are produced in a fast-flow
reactor, yet are typical of photochemical aerosols found in the real
atmosphere, are under study. The produced aerosol is being characterized
both chemically and physically to derive the initial mechanisms for gas-to-
aerosol conversion.

Air Pollution Measurement. The second of the Chemistry and Physics Labora-
tory's two major functional work areas (the first is pollutant transformation
studies) relates to techniques and instrumentation for measuring air pol-
lution. The work area can be subdivided into the following projects.
Ambient Air Particulate Measurement and Analysis Methods. The aim of this
project is to provide EPA with the capability of measuring parameters judged
to be relevant to pollution of the atmosphere by suspended particles.
Parameters of present concern include mass, particle-size distribution,
elemental composition, and visibility attenuation.
Considerable progress has been made in the design of collectors
capable of segregating particles in two size regimes (0 to 3.5 and 3.5 to
20 microns) on a Teflon surface. Exposed filters are examined for mass
determination by Beta ray attenuation, and for elemental composition by
X-ray fluorescence. Filters, filter holders, filter transport mechanisms,
and identification-coding and decoding devices have been or are being de-
signed for total compatibility, resulting in a system geared to the
handling of large numbers of samples with minimum opportunity for human
error.
A major step forward was the development of a simple, sensitive, and
reasonably specific device for the automated collection and quantification
of sulfuric acid mist. Evaluation is planned early in 1974. A similar
device capable of measuring particulate nitrate is also being developed.
27

-------
The X-ray fluorescence technique for measurement of trace elements in
airborne particles has been notably improved through updated computer pro-
gramming that eliminates inaccuracies previously incurred as a result of
variations in particle size.
Future effort will include further improvements in collection, sizing
and analyzing techniques, and development of objective methods of assessing
visibility reduction.
Important progress was made toward development of a rapid method for
the measurement of benzo-a-pyrene, an important carcinogenic component of
pollutant particles.
Personal Exposure Dosimeters. This program, new in 1973, is aimed at pro-
viding simple devices that will record the exposure of individuals to
specific pollutants, independently of movements of those individuals within
and between areas of differing pollutant levels.
A major initial contract-procurement effort is directed toward prep-
aration of a state-of-the-art survey to identify available measurement
techniques, to clarify uncertainties in information needs (e.g., time
resolution, sensitivity, and precision) and to assess the degree to which
it may be reasonably assumed that existing miniaturization techniques can
be applied to the several candidate measurement methods. Concurrently,
procurement is being sought for a small number of prototype sensors for
pilot use and evaluation. Such pilot use will aid in establishing realistic
design criteria for future prototype procurements.
Future effort will be, to a very large extent, indicated by results
of the study alluded to above. It will eventuate in the provision of viable
measurement instruments/methods for the important gaseous pollutants as a
first phase. Subsequent phases will provide devices for the collection of
a particulate matter and for the assessment of physiological effects.
Fine Particulate Methodology. The objective of this program is to develop
a simple, low-cost, 2- or 3-stage device that will effect the dichotomous
collection of respirable and non-respirable particles from ambient air in
a manner compatible with subsequent assessment of their mass and chemical
composition.
During 1973, laboratory and preliminary design work led to initiation
of a procurement for the fabrication of prototype 2-stage collection devices
that will be fieldworthy yet amenable to production at moderate ($2K) cost.
Design criteria include an intake section whose performance will not be
seriously perturbed by wind direction or speed up to 15 km/hr.
Future activity will include field evaluation of the product of the
procurement described above and fabrication of improved second-generation
prototypes. Every effort will be made to provide the capability of real-
time assessment of fine-particle burden in the final product. A corollary
activity is the development of reliable methods for generating monodisperse
aerosols of precisely known particle size, for calibration of sizing
instrumentation.
28

-------
RAPS Measurements and Instrumentation. The objective of this program is
to provide measurement capabilities necessary to complete the Regional Air
Pollution Study (RAPS). The major accomplishment in 1973 was the awarding
of a contract for activation and operation of Regional Air Monitoring
System (RAMS) to Rockwell International.
An X-ray fluorescence analyzer was fabricated, providing RAPS with the
capability of analyzing collected particulate samples for up to 30 elements.
Sensitivity and analysis time are sufficient to handle large numbers of
samples collected over a period of two hours or more.
Twelve automated dichotomous samplers were fabricated to collect par-
ticulate samples, segregating respirable from non-respirable fractions.
A beta-gauge was developed to assess the mass of particles in each fraction
collected. This gauge will be fabricated to handle the same samples
collected for X-ray analysis.
Two separate laser-powered long-path spectrophotometers were developed
for use in RAPS for determining gaseous pollutant burdens, averaged over
line-of-sight paths of up to 1 km. Results will be utilized in improving
pollution-transport modeling capability. These instruments are capable
of analyzing for CO, 0^, SC^, and other pollutants.
A contract was let for fabrication of a fluorescence instrument for
measuring NO^. This, a direct measurement, will assist in confirming data
generated by chemiluminescence (indirect) instruments in RAMS.
A gas-chromatographic instrument capable of measuring acetylene at
levels of 0.1 ppb was fabricated under contract. This capability will be
used in studies applying acetylene as an intrinsic tracer-substance
indicative of automotive traffic.
Further work in this task will consist largely of field trials and
applications of the techniques described above.
Instruments for Measuring Gaseous Pollutants in Ambient Air. The objective
of this program is to provide EPA with both instrumental and laboratory
methods for the measurement of important gaseous pollutants such as ozone,
NO , SO , CO, and hydrocarbons. Its aims are: to provide measurement
capabilfty for a specific pollutant where a need is known to exist; to
improve that capability to an EPA—acceptable level of reliability; to
simplify the hardware resulting from initial efforts to a degree permitting
routine operation of the method or instrument by personnel available to
enforcement agencies; and to seek design optima (or alternate methods/instru-
ments) that will facilitate proliferation at costs commensurate with EPA
resources.
This task has originated, developed, and encouraged commercialization
of an entirely new family of instruments for the measurement of specific
compounds, based on the identification and application of their reactions
with other selected gases to generate light. Instruments based on this
principle are now available and are gaining acceptance for the measurement
of ozone, SO , NO, and N0„. Gas chromatographic techniques have been
developed as part of this task, and have attained commerical success for
29

-------
Lcti>eA Spec&ioAcop-lc Ahaly&AJ> o{, Mn PoZlutanXA
rhe measurement of S0o, H.S, SO, methane, acetylene, and non-methane
hydrocarbons. An improve! laboratory method for the collection and measure-
ment of NO, has been developed and is now being evaluated. Research on
rmt-ical techniques for the measurement of gaseous pollutants, integrated
nver oaths of up to 1 km, has been advanced through the development of a
technique for verifying results obtained against concurrent point-sampling
determinations along the path.
Future work in this area includes improvements in existing chemi-
luminescence instruments, and research on the detection of Plants
t-hroueh their effects up on the electrical properties of solid-state devices.
P t ntially this effort can lead to another new family of instruments of
extremely simple design and low cost. Long-path optical instrumentation
will be further developed and evaluated in the field.
Source Emissions. Activities encompassed in this task include the
f.—:"ticn and description of emissions and their measurement from all mobile
qources1 Possible emissions are investigated and techniques for their
measurement are developed. The operational parameters of this measurement
re defined so that the critical health related questions can be investi-
3 ted Physical and kinetic considerations are addressed in order to define
tactical limits of consideration. Emphasis is on currently nonregulated
P issions that might have the greatest impact on our environment. Techniques
for the measurement of regulated emissions are continually reviewed to assess
their efficacy.

This project was transferred to NERC/RTP from NERC/Cincinnati in FY
1973. The major initial effort was to set up facilities for mobile testing.
Such testing requires that vehicles be operated realistically and that the
average emissions be delineated in a fashion that can be related to their
impact on the environment. Dynamometers have been installed, as well as
analytical test equipment, to measure the emissions. Ongoing projects
include: measurement of oxygenated hydrocarbons, primarily aldehydes;
detailed identification of the hydrocarbon composition of emissions; measure-
ment of particulate emissions, both inorganic and organic; continued assess-
ment of current instrumental techniques for regulated emissions; and
development of instrumentation to assess non-regulated emissions.
In the past year, methodology has been delineated to routinely perform
detailed analysis of hydrocarbons, analysis of nonreactive hydrocarbons,
and objective analysis of diesel odors.
Methodology is being developed to assess sulfate emissions and to
measure SO^ in exhaust.
Major efforts have been expended to define particulate emissions and
the technology for measuring them. This work has lead to the measurement
of particulate from a wide variety of light duty vehicles, including vehicles
operated on nonstandard fuels, with and without catalysts, and with and
without other novel control systems.
Projects are currently under way to extend these techniques to heavy-
duty vehicles and other mobile sources.

Analytical methodology has been developed to measure NO ; techniques
for measurement of CO and hydrocarbons have been updated; an§ aircraft
standards have been reviewed. Nonregulated emissions are being assessed,
particularly from catalyst vehicles, for sulfate, nitrate, and metallic
emissions. Methodology is being sought for potential carcinogenic material
such as polycyclic organics. Research methodology is being reduced to prac-
tical terms for use in more general surveillance wherever possible.
Gaseous Pollutants Emitted from Stationary Sources. The objectives of this
project are to develop and evaluate measurement techniques and monitoring
systems for gaseous emissions in support of these regulations for selected
industrial sources. The R&D program consists of one or more of the
following efforts to meet the required needs: establish the state-of-the-
art; conduct feasibility studies of new or improved concepts and evaluate
their application to specific gas pollutants; develop and evaluate field
prototypes; and evaluate commercially available prototype systems. Methods
and measurement systems include improved manual methods, in-stack instru-
mentation and remote sensors for sulfur-containing compounds, NO , halides,
CO, hydrocarbons, and odorous materials. Also involved is the development
of supporting technology including both flow and temperature measurements
as well as sample conditioning mechanisms.
Commercial prototype monitoring systems have been evaluated on coal-
burning power plants for SO^ and NO^. Research instrumentation for remote
measurements by 13 spectroscopy has been developed and delivered to provide
field research capability. EPA Method 6 (for SO^) was studied for the purpose
of improving end point titration. Method 7 (for NO ) was compared in the
field with a potential alternative method. A disc dilution sampling inter-
32

-------
face was developed in-house and a commercial prototype device was constructed
and tested. A design criteria manual for extractive sampling systems was
prepared. A report on odor measurement was completed for the animal-
rendering industry.
Evaluation and development of compliance test methods and monitoring
systems applied to selected industries will continue in the order in which
emission standards are proposed for Group II, III, IV, etc. sources. Ongoing
activities include: investigation of an integrated mass measurement system
for SC^; further improvement and/or modification of manual methods for NO ;
in-house studies of several new sensor concepts for SO and NO ; development
for an across-the-stack system for measurement of SO , HF, HC1* and NO;
study of odor measurement techniques for specific industries; and development
of a prototype remote analyzer for SO2.
Selection of Criteria for Stationary-Source Measurement Strategies. The
objectives of this activity are to develop performance criteria for pre-
scribed methods and monitoring systems and to establish test procedures by
which criteria can be verified. These criteria and procedures provide the
technical data to support the prescribed methods and monitoring requirements
and to assess the capability and accuracy of equivalent or alternate
measurement methods.
Compliance test methods for NO and SO^ were evaluated at coal-burning
power plants; monitoring systems for these pollutants were tested under
field operating conditions. A technical document was completed on per-
formance specifications and test procedures for monitoring system for NO ,
S02, and visible emissions from Group I stationary sources.
Compliance test methods and monitoring systems for specified pollutant
emissions from selected industries will be evaluated and performance criteria
will be developed as regulations are proposed and promulgated for various
industries. Ongoing activities are concerned with: sulfuric acid mist
monitoring of acid plants; CO; hydrocarbons monitoring guidelines from
petroleum refineries; particulate mass method criteria for Group I sources;
test method criteria for mercury and beryllium; and visible emissions moni-
toring guidelines for Group II sources.
Particulates from Stationary Sources. The objective of this project is to
develop and evaluate measurement techniques and monitoring systems in support
of regulations for selected industrial sources. The R&D program consists
of one or more of the following efforts to meet the required needs: estab-
lish the state-of-the-art; conduct feasibility studies of new or improved
concepts and evaluate their application to specific particle parameters;
develop and evaluate field prototypes; and evaluate commercially available
prototype system.
An evaluation of the manual test method for mass loading was completed
for particulate emissions from power plants and incinerators. A state-of-
the-art study of particulate monitoring for power plant emissions was com-
pleted and preliminary field studies on some prototype monitoring systems
were reported. White smoke guides were developed and are commercially
available for opacity measurements. A remote sensing research monitor for
33

-------
opacity measurement was developed and field studies initiated on design
criteria for a field prototype development. An X-ray fluorescence system
for trace metal analysis has been obtained and is being adapted for chemical
composition studies of particulate emissions.
The particulate mass test method and the opacity monitoring system
applied to selected industries will be evaluated in the order that the
emission standards are proposed for Group I, II etc. sources. Ongoing
activities are concerned with: the development and evaluation of a con-
tinuous mass monitor using the beta-gauge technique; the evaluation of
indirect methods of mass monitoring such as electrical and optical methods;
the development and evaluation of size measurement methods including both
manual and continuous monitoring types; the development of composition
analysis procedures using the X-ray fluorescence technique; and sampling
technology and strategy that include isokineticity, cyclonic flow, nozzle
design, and probe design to provide valid measurement of extracted
particulate samples.
Hazardous Substances Emitted from Stationary Sources. The first group of
substances designated for national emission standards for hazardous air
pollutants includes asbestos, beryllium, and mercury. Future designations
may include such materials as toxic metals (Pb, Cd, V, Ni, Co, Cr, Mn, As,
and Se) or groups of organic matter (POM). The purpose of this work is to
develop measurement methods to obtain reliable emission data and to support
emission standards for these substances. The program consists of one or
more of the following approaches to achieve a working method or system:
feasibility study of new concepts and their evaluation for specific pollu-
tants; development and evaluation of a research prototype; development and
evaluation of a field prototype; and evaluation of commercial prototype
systems.
An engineering prototype analytical system was developed for monitoring
beryllium and cadmium based on a R.F. plasma and A.C. arc-induced emissions
spectroscopy. Briefing documents were prepared on the current technology
available for continuous monitoring of ten metallic elements. Labora-
tory and field studies were conducted on the performance of available instru-
mentation for measuring mercury emissions from several sources. Feasibility
studies were completed for two methods for measuring asbestos: one combines
scanning electron microscopy and X-ray fluorescence analysis; and the other
uses X-ray diffraction.
Activities which are ongoing or will be initiated include: development
of manual sampling and analytical methods for nine toxic metals which might
be designated as hazardous air pollutants; investigation of the reference
method for the two currently designated metals (beryllium and mercury);
evaluation of high resolution X-ray fluorescence spectrometry (XRF) for
multi-elemental analysis; development of standards suitable for XRF instru-
ment calibration; and development of sampling procedures for POM and
polychlorinated biphenyls. A comparative evaluation will also be initiated
for existing analytical procedures for asbestos.
