About the Website

Since the first version of the EFH was released in 1989, 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. In October 2017, EPA released the first chapter update, Chapter 5:Soil and Dust Ingestion with the latest data available (see Downloads for this latest version).
