End Further Info End Preamble Start Supplemental Information


The current guidance document for human exposure assessment, Guidelines for Exposure Assessment, was published in 1992, reflecting the state-of-the-science in the 1970s and 1980s. Since its publication, the field of exposure science has undergone significant transformation in methods and approaches, which EPA has incorporated into its policies and practices to better align with the current state-of-the-science. The 1992 guidelines are being updated to reflect the advancement in exposure science and assessment and Agency policies.

The draft guidelines benefit from over two decades of experience with EPA assessments conducted by Agency programs under their respective authorities and constraints, and from input from external panels, including the National Academy of Sciences and EPA's Science Advisory Board. This draft document builds on topics covered in the 1992 exposure guidelines including planning and scoping for an assessment, data acquisition and use, modeling, and considerations of uncertainty in exposure assessment. It also includes new material on planning and conducting an observational human exposure measurement study and considerations of lifestages and sensitive populations in exposure assessments. These draft guidelines present the most current science used in EPA exposure assessments and incorporates information about the Agency's current policies.
