FACTSHEET: EFD - The Environmental Fate Database

The Environmental Fate Database is a unique compilation of numeric and bibliographic information on the transport and degradation of chemical substances which are released into the environment. Substances covered are predominantly organic compounds, however, extensive physical property and monitoring data relevant to polymers, surfactants, and metals is also available.

Professionals involved in the commercial production, use and disposal of industrial chemicals use the data in the Environmental Fate Database for:

• Evaluating hazardous exposure
• Modeling environmental fate
• Performing structural-activity correlations for the persistence and transport of chemical substances in the environment.

The Environmental Fate Database is organized into 4 files to facilitate easy retrieval of a wide variety of environmental fate and biodegradation data and information. CHEMFATE and DATALOG provide environmental fate data. BIODEG and BIOLOG provide biodegradation and toxicity data.

Experimental environmental fate values for approximately 1,700 chemicals. Each record provides the experimental results, test conditions, summary, comments and a reference. The specific property values available are:

• log P
• pKa
• Soil adsorption constant
• Ultra-violet adsorption
• Water solubility

• Ecosystem
• Hydrolysis
• Microbial degradation
• Degradation in natural systems
• Oxidation & other reactions
• Photolysis

• Log bioconcentration factor
• Evaporation from water - T 1/2
• Henry's Law Constant
• Soil column transport
• Soil thin layer chromatography

• Air monitoring
• Biota monitoring
• Field studies
• Soil Monitoring
• Water Monitoring

Bibliographic references for environmental fate data covering approximately 15,000 chemicals. This file contains over 200,000 records with the data indexed by 18 different data types including -

• Physical properties
• Reaction rates
• Monitoring Studies

• Screening tests
• Biological treatment simulation tests
• Grab sample tests
• Field studies

Bibliographic references for microbial degradation and toxicity data covering approximately 7,000 chemicals. This file is made up of over 47,000 records. References can be obtained from six categories:
