Abstract

The "Exposure Factors Handbook" (EFH or "Handbook") provides a summary of the available statistical data on various factors used in assessing human exposure. This report is addressed to exposure assessors inside the Agency as well as outside, who need to obtain data on standard factors to calculate human exposure to toxic chemicals. These factors include: drinking water consumption, soil ingestion, inhalation rates, dermal factors including skin area and soil adherence factors, consumption of fruits and vegetables, fish, meats, dairy products, homegrown foods, breast milk intake, human activity factors, consumer product use, and residential characteristics. Recommended values are for the general population and also for various segments of the population who may have characteristics different from the general population. EPA has strived to include full discussions of the issues that assessors should consider in deciding how to use these data and recommendations.
The EPA Office of Research and Development's National Center for Environmental Assessment (NCEA) has prepared this handbook to address factors commonly used in exposure assessments. This handbook was first published in 1989 in response to requests from many EPA Program and Regional Offices for additional guidance on how to select values for exposure assessments.

This document provides a summary of the available data on consumption of drinking water; consumption of fruits, vegetables, beef, dairy products, and fish; soil ingestion; inhalation rates; skin surface area; soil adherence; lifetime; activity patterns; body weight; consumer product use; and the reference residence.
