Framework for Ecological Risk Assessment

Risk Assessment Forum

This Framework served as the foundation for, and has been superseded by, EPA's 1998 Ecological Risk Assessment Guidelines.

Increased interest in ecological issues such as global climate change, habitat loss, acid deposition, reduced biological diversity, and the ecological impacts of pesticides and toxic chemicals prompts this U.S. Environmental Protection Agency (EPA) report,' A Framework for Ecological Risk Assessment ("Framework Report"). The report describes basic elements, or a framework, for evaluating scientific information on the adverse effects of physical and chemical stressors on the environment. The framework offers starting principles and a simple structure as guidance for current ecological risk assessments and as a foundation for future EPA proposals for risk assessment guidelines.
