ACTION: Notice of availability of final document and CD-ROM.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (EPA) announces the 
availability of a final document, Exposure Factors Handbook, Volumes I-
III (EPA/600/P-95/002Fa, EPA/600/P-95/002Fb, and EPA/600/P-95/002Fc; 
August 1997) and Exposure Factors Handbook CD-ROM (EPA/600/C-99/001, 
February 1999), prepared by the National Center for Environmental 
Assessment-Washington (NCEA-W), within the Office of Research and 
Development of the EPA. The purpose of the document and CD-ROM is to 
provide a summary of the available statistical data on various factors 
used in assessing human exposure. This Handbook will serve as a 
resource for 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, and home-grown 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. NCEA has strived 
to include full discussions of the issues that assessors should 
consider in deciding how to use these data and recommendations. The CD-
ROM contains an interactive version of the Exposure Factors Handbook. 
The CD-ROM has word search capabilities, down-loadable tables, 
hypertext links to various chapters in the document, and key 
references.

NCEA web site at http://www.epa.gov/ncea/exposfac.htm. A limited number
