review the external review draft document titled, ``An Exploratory Study: Assessment of Modeled Dioxin Exposure in Ceramic Art Studios'' (EPA/600/R06/044A). The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development. The purpose of this report is to describe an exploratory investigation of potential dioxin exposures to artists/ hobbyists who use ball clay to make pottery and related products. Dermal, inhalation and ingestion exposures to clay were measured at the ceramics art department of Ohio State University in Columbus, OH. Estimates of exposure were made based on measured levels of clay in the studio air, deposited on surrogate food samples and on the skin of artists. EPA is releasing this draft document solely for the purpose of predissemination peer review under applicable information quality guidelin ]]> http://thefederalregister.com/d.p/2007-11-29-E7-23158 Thu, Nov 29 2007 11:00:00 GMT
