Notice of peer-review panel workshop.


The Environmental Protection Agency (EPA) is announcing that Eastern Research Group, Inc. (ERG), an EPA contractor for external scientific review, will convene an independent panel of experts and organize and conduct a peer-review workshop, to review the external review draft document titled, “Child-Specific Exposure Factors Handbook” (EPA/600/R-06/096A). EPA provided an opportunity for public comment on the draft document from October 2006 to January 2007. The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development. The “Child-Specific Exposure Factors Handbook” provides a summary of statistical data on various exposure factors used in assessing children's exposures, including: Drinking water consumption; soil ingestion and mouthing behavior; inhalation rates; dermal factors including skin surface area and soil adherence factors; consumption of retail and home-grown foods; breast milk intake; and human activity pattern data. Once completed, this report will serve as a resource for exposure assessors for estimating children's exposures. An interim final version of this handbook was published in 2002. This updated version provides analysis of exposure factors data using the age groups for children recommended in the EPA document entitled, “Guidance on Selecting Age Groups for Monitoring and Assessing Childhood Exposures to Environmental Contaminants” (EPA/630/P-03/003F) (Available on line at​ncea/​cfm/​recordisplay.cfm?​deid=​146583).
