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;

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. An external peer-review workshop is expected to be 
scheduled at a later date and announced in the Federal Register. The 
public comment period and the external peer-review workshop are 
separate processes that provide opportunities for all interested 
parties to comment on the document. 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. When finalizing the draft document, EPA intends to 
consider any public comments that EPA receives in accordance with this 
notice.
