Abstract Ecological risk assessments are used by the U.S. Environmental Protection Agency (USEPA) and other governmental agencies to assist in determining the probability and magnitude of deleterious effects of hazardous chemicals on plants and animals. These assessments are important steps in formulating regulatory decisions. The completion of an ecological risk assessment requires the gathering of ecotoxicological hazard and environmental exposure information. The information is evaluated in the risk characterization section to assist in making the final risk assessment. ASTER (Assessment Tools for the Evaluation of Risk) was designed by the USEPA Environmental Research Laboratory-Duluth (ERL-D) to assist regulators in producing risk assessments. ASTER is an integration of the AQUIRE (AQUatic toxicity Information Retrieval System) and QSAR (Quantitative Structure Activity Relationships) systems. AQUIRE is a database of aquatic toxicity tests and QSAR is comprised of a database of measured physicochemical properties, and various QSAR models that estimate physicochemical and ecotoxicological endpoints. ASTER will be available to international governmental agencies through the USEPA National Computing Center.
