Project Abstact

The purpose of this project is to investigate the potential dioxin exposure to artists/hobbyists who use ball clay to make pottery and related products. This project will focus on artists working in a ceramics studio where exposure could occur via three pathways: particle inhalation, incidental ingestion and dermal contact. Levels of clay will be measured in the studio air, deposition surfaces and skin of artists. It is anticipated that no samples will need to be analyzed for dioxin. Rather, all samples will be analyzed for total clay levels and theoretical dioxin exposures would be estimated using information on historical measurements of dioxin levels in ball clay. Data gathering completed in 2004, internal review of report completed in Summer 2005, external peer review completed in 2007, final in 2008. See www.epa.gov/ncea for final report
