An Exploratory Study: Assessment of Modeled Dioxin Exposure in Ceramic Art Studios (2008 Final)
Notice [11/25/08] EPA is announcing the availability of this final report.
In 1996, dioxins were discovered in ball clay as a result of an investigation to determine the sources of elevated dioxin levels in two chicken samples from a national survey of poultry. The investigation indicated that the contamination source was ball clay added to chicken meal as an anti-caking agent. The purpose of this study was to evaluate another potential exposure scenario associated with ball clay, namely its use in ceramic art studios. This exploratory investigation makes preliminary exposure estimates that can be used to evaluate whether more detailed follow-up analyses will be needed.
