ENVIRONMENTAL PROTECTION AGENCY
[FRL-7032-9]
Summary Report of the Technical Workshop on Issues Associated
With Considering Developmental Changes in Behavior and Anatomy When
Assessing Exposure to Children
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of availability of a final report.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency's (EPA) Risk Assessment
Forum (RAF) announces the availability of a final report, Summary
Report of the Technical Workshop on Issues Associated with Considering
Developmental Changes in Behavior and Anatomy when Assessing Exposure
to Children (EPA/630/R-00/005, December 2000). The report presents
information and materials from a peer involvement workshop held by the
RAF. Eastern Research Group, Inc., an EPA contractor, organized and
convened the meeting on behalf of the RAF in Washington, DC on July 26
and 27, 2000. The meeting discussions focused on how to consider age-
related changes in behavior and physical development when assessing
childhood exposures to environmental contaminants. These discussions
are part of EPA's ongoing efforts to improve the assessment of risk to
children.
ADDRESSES: The document will be made available electronically through
the Risk Assessment Forum's web site (www.epa.gov/ncea/raf/rafpub.htm).
A limited number of paper copies will be available from the EPA's
National Service Center for Environmental Publications (NSCEP), P.O.

SUPPLEMENTARY INFORMATION: An Agency workgroup convened under the
auspices of the RAF has been exploring children's exposure assessment
issues. This workgroup has concluded that a major issue facing Agency
assessors is how to consider age-related changes in behavior and
physiology when preparing exposure assessments for children. Children's
behavior changes over time in ways that can have an important impact on
exposure. Further, children's physiology changes over time in ways that
can impact both their exposures and their susceptibility to certain
health effects. There are two aspects to these physiological changes.
First, there are anatomical changes resulting from physical growth.
Second, there are changes in pharmacokinetics and pharmacodynamics that
affect the absorption, distribution, excretion and effects of
environmental contaminants. The Agency is examining the
pharmacokinetic/pharmacodynamic changes in children through other
efforts and future meetings on this topic are anticipated. The July
2000 workshop focused on incorporating age-related changes in behavior
and anatomy into Agency exposure assessments.
