Exposure Factors Handbook: 2009 Update

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period.

SUMMARY: EPA is announcing a 60-day public comment period for the external review draft document titled, ``Exposure Factors Handbook: 2009 Update'' (EPA/600/R-09/052A), which was prepared by the National

Center for Environmental Assessment (NCEA) within EPA's Office of

Research and Development (ORD). The Exposure Factors Handbook provides a summary of the available statistical data on various factors used in assessing human exposure. This Handbook is aimed at exposure assessors inside the Agency as well as those outside who use data on standard factors to calculate human exposure to toxic chemicals. These factors include: drinking water consumption; mouthing behavior; soil ingestion rates; inhalation rates; dermal factors, including skin area and soil adherence factors; consumption of fruits and vegetables, fish, meats, dairy products, and homegrown foods; breast milk intake; human activity factors;

EPA intends to forward the public comments that are submitted in accordance with this notice to the external peer-review panel prior to the meeting for their consideration.
