     In November 1979, SRC initiated the development of the Environmental Fate Data Base (EFDB) under the sponsorship of the EPA. This computerized database, developed and maintained at SRC under the direction of Dr. Philip Howard, serves the following purposes:

1.To allow rapid access to all available fate data on a given chemical without having to resort to expensive, time consuming, and inefficient primary literature searches;
2.To identify critical gaps in the available information to facilitate planning of research needs; and
3.To provide a data source for constructing structure-activity correlations for degradability and transport of chemicals in the environment.

The EFDB is a tremendous aid in identifying persistent chemical classes, as well as physical or chemical properties that may correlate to particular behavior in the environment. The EFDB is comprised of several interrelated files, DATALOG, CHEMFATE, BIOLOG, and BIODEG. These files, described
below, are available individually in a MS Windows version or all four can be accessed using a direct query through SRC's VAX


DATALOG is a bibliographic file indexed by Chemical Abstract Service (CAS) registry number that contains eighteen types of environmental fate data. Since individual articles require only cursory examination, no experimental values are entered into the file, and thus, large numbers of chemicals can be rapidly incorporated. This file is the largest in the EFDB, containing over 240,000 records on 15,000 chemicals. DATALOG indicates where Environmental fate and exposure data can be found by using the
following 18 different indexing terms:

Dissociation constant
Effluent concentrations
Evaporation from water
Food and crop concentrations
Field studies
Henry's Law constant
Occupational concentrations
Octanol/water partition coefficent
UV spectra
Vapor pressure
Water solubility


CHEMFATE is a data value file containing 23 categories of environmental fate and physical/chemical property information on commercially important chemical compounds. Actual experimental values (rate constants, experimental conditions, physical properties, etc.) are abstracted and retained in the file.
CHEMFATE contains 17,214 records on 1,728 chemicals. Recently, recommended physical property values were collected for the SARA Section 313 TRI chemicals.


BIOLOG, or the Microbial Degradation/Toxicity File, provides sources of microbial toxicity and biodegradation data. It is is more detailed than DATALOG, but does not include experimental values.
BIOLOG contains 48,272 records on 6,765 chemicals.


The fourth file, BIODEG contains experimental values as in CHEMFATE, but only relating to biodegradation subjects. In addition, BIODEG contains evaluation codes that can be used for structure/biodegradability correlations. This file contains actual experimental results on biodegradation studies for approximately 700 chemicals. Experimental details, such as chemical concentration and rate of degradation, are included.

The EFDB is tied together through XREF, the bilographic file that contains full references on the 23,000 articles cited.

The PC version of the EFDB runs on all IBM compatibles. Although disk space is a limitation for full instalation of the EFRDB, it is also available on, and can be run from, a CDROM.
