CARCINOGEN RISK ASSESSMENT - INTERNATIONAL COMPARISON

This report compares carcinogen risk assessment methodologies used by various countries as a basis for regulatory actions. The methodologies are based on scientific analysis, but national governments have used different approaches for dealing with uncertainties in the analysis. Both scientific judgment and social policy play a role in resolving scientific uncertainties. Since risk assessment methodologies, and subsequent regulatory policies, ultimately impact world trade, efforts to harmonize approaches to risk assessment are important. This paper represents an effort to understand current approaches to carcinogen risk assessment as a first step toward harmonization. (C) 1994 Academic Press, Inc.
