The development of the latest version of the Exposure Factors Handbook (EPA/600/P-95/Fa, Fb, and Fc) has brought to light the need for a more comprehensive program that addresses issues related to exposure factors. The need for the most up-to-date and accurate data on exposure factors used in assessing exposure to contaminants in the environment is of high priority to exposure assessors throughout the U.S. The completion of the Exposure Factors Handbook has only been the first step in fulfilling this need. Many data needs have been identified and follow up research is underway to address some of the data gaps. This web page is intended to provide a focal point where the most current information and data on exposure factors can be found. |
