ENVIRONMENTAL PROTECTION AGENCY

[FRL-8044-6; Docket ID No. EPA-HQ-ORD-2006-0134]

 
A Framework for Assessing Health Risks of Environmental Exposures 
to Children

AGENCY: Environmental Protection Agency.

ACTION: Notice of public comment period.

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

SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing a 
45-day public comment period for the external review draft document 
titled, ``A Framework for Assessing Health Risks of Environmental 
Exposures to Children'' (EPA/600/R-05/093A). The draft document was 
prepared by the National Center for Environmental Assessment (NCEA) 
within EPA's Office of Research and Development (ORD).
    For external scientific peer review, EPA has hired Eastern Research 
Group, Inc. (ERG) to convene an independent panel of experts and 
organize and conduct an external peer-review workshop. The date and 
location for the external peer-review workshop will be announced in a 
separate Federal Register notice, once that information is obtained by 
EPA. 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. In addition to consideration by 
EPA, all public comments submitted in accordance with this notice will 
also be forwarded to ERG for the external peer-review panel prior to 
the workshop.
    EPA is releasing this external review draft document solely for the 
purpose of pre-dissemination peer review under applicable information 
quality guidelines. This draft document has not been formally 
disseminated by EPA. It does not represent and should not be construed 
to represent any Agency policy or determination.

DATES: The 45-day public comment period begins March 14, 2006, and ends 
April 28, 2006. Technical comments should be in writing and must be 
received by EPA by April 28, 2006.

ADDRESSES: The draft document and EPA's peer-review charge are 
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. A limited number of 

paper copies are available from the Technical Information Staff, NCEA-
W; telephone: 202-564-3261; facsimile: 202-565-0050. If you are 
requesting a paper copy, please provide your name, mailing address, and 
the document title, ``A Framework for Assessing Health Risks of 
Environmental Exposures to Children'' (EPA/600/R-05/093A).
    Comments may be submitted electronically via http://www.regulations.gov
, by mail, by facsimile, or by hand delivery/

courier. Please follow the detailed instructions

SUPPLEMENTARY INFORMATION:

I. Information About the Document

    Over the past decade, there has been a dramatic increase in the 
recognition of, and public health concern for, the vulnerability of 
children to exposure to environmental agents. Children have unusual 
patterns of exposure and have vulnerabilities to chemical agents that 
are quite distinct from those of adults, and thus require special 
consideration in risk assessment. Children often have 
disproportionately higher exposures to certain environmental toxicants 
because, pound-for-pound of body weight, children have higher food and 
water intake and breathe more air than adults. Metabolic pathways in 
the young, especially in the first few months after birth, are 
immature, and the ability to detoxify environmental agents is different 
from that of adults. In addition, behavior and activity patterns of 
children often magnify their exposures. These factors imply that 
children are likely to have more substantial exposures than adults to 
certain environmental agents. This document attempts to organize and 
present current knowledge and practices in a programmatic framework for 
assessing human health risks from exposures to environmental agents 
from prior to conception through adolescence. It describes this 
framework within the current Agency risk assessment paradigm, and 
includes problem formulation, analysis and risk characterization as 
discrete steps in the process. Moreover, this document focuses on mode 
of action as a context for considering the toxicokinetic and 
toxicodynamic differences between children and adults, and considers 
approaches for risk assessment in the context of uncertainty and 
variability in exposure and critical windows of development.
