1.0 Introduction
The objective of this report is to compile and briefly describe
the available, computerized sources of information on pollutants. In
some instances the data file deals with and contains only information on
pollutants. In other cases, the information on pollutants represents
only a small portion of a much larger data bank. Systems with restricted
accessibility have, in general, not been included in the list. This list
has been compiled with a view to possible users in the area of the Research
Triangle Park, North Carolina, so the services of the EPA library of the
Research Triangle Park and the North Carolina Science and Technology
Research Center are stressed. There are many other centers throughout
the country with access to several of the systems mentioned. Information
on access to these systems can be obtained from the agency itself or from
libraries in the geographical area of interest.
In general, the types of services available are mentioned for every
data bank. The user may choose an organization which supplies current
awareness searches in a given area of interest, or one which supplies
retrospective literature searches, either of a standard format or tailored
to the customer's individual application. Some organizations have pub-
lished data compilations - abstracts or bibliographic data - available in
published form. Services available from each organization have been
enumerated as far as possible.
The contributions of Ms. Elizabeth Smith (EPA library, Research
Triangle Park) and Dr. Monica Nees (North Carolina Science and Technology
Research Center) to the preparation of this list are gratefully acknowledged.

3.0 Computerized Sources of Data on Pollutants
ABSTRACTS ON HEALTH EFFECTS OF ENVIRONMENTAL POLLUTANTS (KEEP)
Biosciences Information Service of Biological Abstracts
2100 Arch Street
Philadelphia, Pennsylvania 19103
(215) 568-4016
KEEP was created by BIOSIS to fill the need for current information
on environmental pollution. Complemented by a machine-readable data base,
KEEP is designed to serve individuals and organizations engaged in research
on health aspects of pollution, including occupational hazards and industrial
medicine. In each printed issue of KEEP, approximately 1,000 abstracts di-
rect the scientist to pertinent research in the field. The magnetic tape
version of KEEP omits the abstracts, but includes all bibliographic in-
formation, keywords and other indexing entries.
KEEP covers articles on occupational health and industrial medicine,
chemicals or substances in the environment with emphasis on human health,
general reviews and original papers reporting potentially harmful effects
of pollutants on humans, studies of lower vertebrates used as indicators
of the substances toxic to man, vertebrates and invertebrates as vectors
in the food chain, and reports of analytical methods for examining bio-
logical tissues or fluids.
The magnetic tapes contain title, keywords, subject heading and
CHEMICAL ABSTRACTS Service registry numbers. The tapes are available by
lease only, date from 1972 to the present, and are incremented by some
12,000 source items per year. This service is available on-line as part
of TOXLINE through the EPA library.

AEROMETRIC AND EMISSIONS REPORTING SYSTEM (AEROS)
U. S. Environmental Protection Agency
Office of Air and Waste Management
Research Triangle Park, N. C. 27711
Information, National Air Data Branch: (919) 688-8146
AEROS is a complex and comprehensive computer-based system established
by the National Air Data Branch to collect, store and analyze air pollution
data. AEROS is composed of several subsystems, some of which can function
as independent data systems. The two basic segments of AEROS are: (1) the
AEROS Data System, which collects, stores, and reports air pollution data
to be put into the system; (2) the AEROS Analysis System, which draws data
from the Data System and uses them to answer questions regarding the nature
and causes of air pollution, predictions of future problems, legal action
which should be taken, and related problems.
Parts of AEROS Data System are:
(1) NATIONAL EMISSIONS DATA SYSTEM (NEDS) - NEDS stores and reports
source and emission- related data for particulates, SO , NO , CO, and
X X
hydrocarbons. NEDS describes 78,000 point sources and 3,200 area
sources. Information is reported to AEROS via emission inventory
questionnaires, State Implementation Plan background data, and semi-
annual reports.
(2) STORAGE AND RETRIEVAL OF AEROMETRIC DATA (SAROAD) - SAROAD stores
and reports information gathered by ambient air monitoring networks
across the country. SAROAD provides information on pollutant levels,
weather information, and sites, and collects information for AEROS
from over 4,000 active air monitoring sites across the nation.
(3) SOURCE TEST DATA SYSTEM (SOTDAT) - SOTDAT stores data collected
from extensive tests conducted at pollution sources, provides re-
tention of data too specific to be stored in the NEDS data base, and
-------
provides source test data for development of emission estimation
factors.
(4) EMISSION HISTORY INFORMATION SYSTEM (EHIS) - EHIS determines
and reports pollution emission estimates for the U. S. for previous
years, provides data for development or evaluation of national air
pollution control strategies, and provides basic prediction data for
detecting future problems.
(5) STATE IMPLEMENTATION PLAN SYSTEM (SIPS) - SIPS stores the text
of state regulations pertaining to limitation of air pollutant emis-
sions and stores federally promulgated regulations when implemented.
(6) FEDERAL POWER COMMISSION FORM NO. 67 (FPC-67) - FPC-67 stores and
selectively outputs descriptive and operation data from power plants
over 25 megawatt capacity as reported yearly to the Federal Power
Commission and facilitates a complete and comprehensive overview of
power-generating facilities and associated air pollution problems.
(7) HAZARDOUS AND TRACE EMISSIONS SYSTEM (HATREMS) - HATREMS stores
data collected regarding emissions of air pollutants that are not
included in NEDS: emissions other than particulates, sulfur oxides,
nitrogen oxides, carbon monoxide, and hydrocarbons.
(8) ENERGY DATA SYSTEM (EDS) - EDS gathers and reports energy-related
data, such as fuel usage, from the other data bases of the AEROS system.
(9) QUALITY ASSURANCE MONITORING INFORMATION SYSTEM (QAMIS) - QAMIS
stores data on the procedures, equipment, personnel, and other re-
lated information about data-acquiring agencies and provides a
mechanism for, monitoring and analysis of data gathering techniques.
-------
The AEROS Analysis Systems are:
(1) COMPUTER ASSISTED AREA SOURCE EMISSIONS (CAASE) - CAASE proportions
county, area-source data into smaller areas based on population and
similar factors to show pollution levels within grids and provides a
mechanism for usage of NEDS area source data in mathematical air quality
models.
(2) REGIONAL EMISSIONS PROJECTION SYSTEM (REPS) - REPS predicts emis-
sions from geographical area or source to the year 2000, identifies
probable future problems, and provides a mechanism for manipulation to
allow prediction of the effect of changing conditions (jL. e_., less
strict regulations).
(3) SOURCE INVENTORY AND EMISSION FACTOR ANALYSIS (SIEFA) - SIEFA
computes estimated errors in emissions data due to inaccuracies in
data collection and estimation procedures and provides a mechanism
for determination of areas where data improvement is required.
(4) AIR POLLUTANT EMISSIONS REPORT (APER) - APER provides a mechanism
for organizing and tracking communications with air pollution sources
and for coordinating data handling and acquisition. APER serves as a
data management tool.
(5) WEIGHTED SENSITIVITY ANALYSIS PROGRAM (WSAP) - WSAP computes the
tolerable error in emissions data.
(6) PRE-MODELING DATA OUTPUT (PREMOD) - PREMOD makes air pollution
data compatible with mathematical modeling computer programs and pro-
vides a mechanism for data output for determination and prediction of
ambient air quality for a specific area from source data.
-------
The EPA air data systems are primarily used by government agencies
although the private sector is becoming more aware of the advantages in
utilizing a common data base. Information from the AEROS system can be
accessed through standardized publications or by custom data retrieval
requests.

Carcinogenesis Bioassay Data System
National Institutes of Health
Bethesda, Maryland 20014
(301) 496-5591
The Carcinogenesis Bioassay Data System (CBDS) provides for the
collection, maintenance, and reporting of bioassay information. Bio-
assay investigators provide input data to CBDS. Background data are
collected about the chemical and chemical preparations, the experi-
mental environment, the animal colonies, and groups. Throughout the
experiments, observation data are gathered. A complete pathology
report is submitted following the death of each individual animal.
The CBDS began operation in early 1972. Thousands of records and
millions of data items are maintained. The National Cancer Institute
uses CBDS to monitor and evaluate bioassay investigations.
Currently the recipients of CBDS data are holders of contracts in
the area. An output clearinghouse to receive requests, initiate com-
puter runs, and forward output to the contractor is currently being
established. Present relationships between investigators and CBDS are
rather informal.

The Environmental Mutagen Information Center was organized at the
Oak Ridge National Laboratory in 1969. EMIC collects, organizes, and
disseminates chemical mutagenesis information.
Information contained in the EMIC data file is either pertinent
to the testing of chemicals in one of the many available mutagenic
assay systems or contains data useful for understanding the known or
suspected mutagenic activity of environmental chemical agents. The
information collected for this data base is processed and disseminated
to the scientific community. The EMIC citation file currently con-
tains 15,000 entries for articles published primarily since 1969 in
about 1,600 publication sources. This information file contains bib-
liographic details and keywording of chemicals, organisms, and systems
studied.
Bibliographies with permuted title and author indices are printed
and distributed to individuals active in mutagenesis research. Special
literature compilations are selected and printed in response to spe-
cific questions in the scientific community. EMIC has initiated a
tabular abstraction of selected data; these data are entered into
computer files linked to the citation file. Literature reviews are
prepared by the EMIC staff at periodic intervals, involving the wide-
spread occurrence of specific mutagens in the human population.
Yearly reviews of the literature reporting mutagenic action of
chemicals are produced by EMIC and are available upon request.

atic query program to be of value both for on-line response to spill
incidents and for summary evaluations relating to direct enforcement
and research activities. Both numerical data and interpretive com-
ments are maintained in the files and constant updating is performed.
The coverage encompasses oil and hazardous material spills, in-
cluding physical, chemical, commercial and toxicological properties
of radioisotopes, oils, oil spill treating agents, pesticides and
industrial chemicals with emphasis on the deleterious effects these
agents may have on water quality.
Sources of input include journal articles, books, papers pre-
sented at symposia, compendia, government reports, and basic refer-
ence texts. EPA maintains on-line access to the data base by means
of terminals compatible with the Battelle terminal, and on-line access
is limited.

Probability Based Matching System (PBM)
Self-Training Interpretive and Retrieval Systems (STIRS)
Cornell Research Park
Ithaca, New York 14853
(607) 256-3748
PBM and STIRS are complementary computer techniques for the identi-
fication, retrieval, and interpretation of unknown mass spectra, developed
at Cornell University by Professor F. W. McLafferty and his research group.
These techniques are available through Cornell's Office of Computer Ser-
vices. The programs are run on Cornell's central computer and can be
accessed through the TYMNET communications network.
PBM identification matches the unknown mass spectrum against spectra
contained in the reference file; PBM is designed to identify individual
components in mixtures as well as the spectra of pure compounds. PBM
searches the complete unknown spectrum for the most important peaks in
each reference spectrum and weighs the importance of both the mass and
abundance values to use the most significant peaks in the reference
spectrum.
If PBM does not find a reference spectrum that matches sufficiently
closely, the unknown spectrum can then be examined by the STIRS programs.
STIRS interpretation of an unknown mass spectrum utilizes eleven different
classes of spectral data which are sensitive to particular types of mo-
lecular structural features. Spectral data of the unknown in each class
are compared by the computer to the corresponding data of each reference
spectrum to find the best matches. For each data class a high occurrence
of a particular structural feature in the compounds of best matches is
strong evidence for the presence of that feature in the unknown molecule.
A statistical evaluation of the STIRS results provides confidence level
-------
52
predictions for 200 common substructures. The data base for STIRS has
been limited to those compounds containing H, C, N, 0, F, Si, P, S, Cl,
Br, and I of natural isotopic abundances, with not more than the one
mass spectrum of each compound.
An unknown spectrum need be submitted to the PBM/STIRS system only
once. PBM will attempt to locate the unknown in the reference file. If
PBM is unsuccessful, STIRS can optionally be invoked to provide clues to
the structure of the unknown.
As of June, 1975, the reference files contain data on about 28,000
different compounds and a total of approximately 36,000 mass spectra. To
maximize the probability of identifying an unknown in spite of varia-
tions in instrument type, procedure, etc., multiple spectra of the same
compound have been allowed in the file. The reference file includes
nearly 24,000 mass spectra of the "Registry of Mass Spectral Data" (John
Wiley, Inc.), plus spectra collected at Cornell and elsewhere. PBM/STIRS
files are updated frequently as new spectra are obtained.
The reference files also include compound names, molecular weights,
elemental composition, Wiswesser Line Notation description, source of
the spectrum and the reference spectrum itself.

ongoing research in the areas of earth sciences, behavioral sciences,
physics, mathematics, energy, chemistry, chemical engineering, bio-
logical and environmental services, engineering, materials, elec-
tronics, social sciences, agricultural sciences, and medical sciences.
The project information SSIE collects is drawn from most of the large
sources of research support in the United States, with project infor-
mation voluntarily submitted by some 1,300 government agencies and
private organizations that support or conduct research. The current
file, covering the past two government fiscal years, contains records
on more than 200,000 ongoing or recently completed projects.
The basic record in the SSIE systems is a one-page Notice of
Research Project (NRP). Each notice contains information about
individual projects: supporting organization and grant/contract
number; performing organization name and address; name, department,
and specialty of the principal investigator; names of co-investigators;
project title; period covered by the NRP; funding; and, in most cases,
a 200-word technical description of the project.
Nearly 30,000 subject index points are presently in use in the
several hundred life and physical sciences indexes. Project summaries
are indexed to an average of 14 subject categories, each of which
