A new online database, designated the FATE database, has been developed for the interactive retrieval of kinetic and equilibrium constants that are needed for assessing the fate of chemicals in the environment. The database contains values for twelve parameters, but may not contain a value for each parameter for each chemical. As of June 1991, the database contained values for about 200 chemicals. Unique features of the database include experimental data that are extracted only from primary references and pertinent experimental conditions that are entered into the database to assure the user of the credibility and applicability of a value. A newly developed computer program is used to extrapolate hydrolysis rate constants to a standard format. Acidic, basic and neutral contributions are combined to calculate the overall hydrolysis rate constant and the half-life of the chemical at 25 C and pH 7. The data also are reported as second-order acidic and basic rates and a first-order neutral rate at 25 C. Products of transformation are listed for degradation processes when available. A newly developed computerized expert system will be applied to compute accurate fate constant values. The expert system has the capability of crossing chemical boundaries to cover all organic compounds.
