SUPPLEMENTARY INFORMATION:

I. Information About the Document

The purpose of this report is to describe an exploratory investigation of potential dioxin exposures to artists and 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, Ohio. 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. The measurements were made in two separate studies, one in April 2003 and one in July 2004. This draft assessment combines the results of these two studies.
