Exposure Factors Program
Report Information
The development of the latest version of the Exposure Factors Handbook (EFH): 2011 Edition (EPA/600/R-09/052F) has maintained the need for a more comprehensive program that addresses issues related to exposure factors. Since the first version of the EFH was released in 1997, 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 2011 edition 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 "one-stop-shop" where the most current information and data on exposure factors can be found.
