Summary of the U.S. EPA Colloquia on a Framework for Human Health Risk Assessment (Volume 1, 1997)
The U.S. Environmental Protection Agency (EPA) has recognized the need to develop a framework for human health risk assessment that puts a perspective on the approaches in practice throughout the Agency. The framework will be a communication piece that will lay out the scientific basis, principles, and policy choices underlying past and current risk assessment approaches and will provide recommendations for integrating/harmonizing risk assessment methodologies for all human health endpoints. As an initial step in this process, the Agency's Risk Assessment Forum organized a colloquium series, consisting of two internal colloquia. The colloquia brought together EPA scientists for a dialogue on various scientific and policy issues pertaining to EPA's cancer and noncancer risk assessment approaches.
The first colloquium, held on September 28 and 29, 1997, in Arlington, Virginia, focused on the role of mode of action information in re-examining and developing new risk assessment approaches. The present document summarizes discussions held during this colloquium. (See "Related Entries" for a aummary report of a follow-on colloquium held in 1998.)
