Abstract : This report is a review of the exposure assessment guidelines recommended by the U.S. Environmental Protection Agency, other federal and state agencies, and nongovernmental research groups. Emphasis is placed on describing the general concepts used in exposure assessments and in identifying the population-, site- and chemical-specific exposure parameters that are used or recommended by these groups. Also included is an overview of the recommendations made by EPA's Science Advisory Board, and the National Research Council concerning current exposure assessment methodologies. The primary objective of this report is to identify those steps in the exposure assessment process for which there might be alternative approaches which may lead to an overall improvement in the cost efficiency and quality of the exposure assessments conducted on federal sites.
