Exposure Factors Handbook: 2011 Edition; Release of Final Report
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of Availability.
-----------------------------------------------------------------------
SUMMARY: On September 30, 2011, the EPA publically released the final
report entitled Exposure Factors Handbook: 2011 Edition. The document
was prepared by the National Center for Environmental Assessment (NCEA)
within EPA's Office of Research and Development. The Exposure Factors
Handbook: 2011 Edition provides information on various physiological
and behavioral factors commonly used in assessing exposure to
environmental chemicals. The handbook was first published in 1989 and
was updated in 1997. This edition incorporates information made
available from 1997 up until July 2011. It also reflects the revisions
made to the Child-Specific Exposure Factors Handbook, which was last
updated and published in 2008. Each chapter in the Exposure Factors
Handbook: 2011 Edition presents recommended values for the exposure
factors covered in that particular chapter's exposure route as well as
a discussion of the underlying data used in developing the
recommendations.
The Exposure Factors Handbook: 2011 Edition (EPA/600/R-09/052F) is
available via the Internet at http://www.epa.gov/ncea.
DATES: This report was posted publically on September 30, 2011.
ADDRESSES: The report is available primarily via the Internet on the
National Center for Environmental Assessment's home page under the
Recent Additions and Publications menus at http://www.epa.gov/ncea.
Paper copies of the report are not available. A limited number of CD-
ROMs will be available from the Information Management Team, NCEA;
telephone: 703-347-8561; facsimile: 703-347-8691. If you are requesting
a CD-ROM, please provide your name, your mailing address, and the
document title.
FOR FURTHER INFORMATION CONTACT: For additional information, contact
the National Center for Environmental Assessment; Jacqueline Moya;
telephone: 703-347-8539; or e-mail: [email protected].
SUPPLEMENTARY INFORMATION:
I. Information About the Project/Document
The Exposure Factors Handbook: 2011 Edition provides a summary of
the available statistical data on various factors used in assessing
human exposure. 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; human milk intake; human activity factors; consumer product use;
and building characteristics. This handbook is intended for use by
exposure assessors, within the Agency as well as those outside, as a
reference tool and primary source of exposure factor information. It
may be used by scientists, economists, and other interested parties as
a source of data and/or U.S. EPA recommendations on numeric estimates
for behavioral and physiological characteristics needed to estimate
exposure to environmental agents. Recommended values are available for
the general population and, for most of the exposure factors, are also
available by age, sex, as well as for other populations that may have
characteristics different from the general population.
