| Research Abstract |
The presence of dioxins in ancient clays presented an interesting scientific quandary. We investigated occurrence and profiles of dioxins in nationwide kaolin clays, and estimated inventory of dioxins in ceramic industry based on combustion experiments of kaolin clay. Moreover, this study focused on relationship between depositional process of kaolin clay and distribution of dioxins in related materials, as well as isotope ratios of dioxins in kaolin clay to reveal origin of dioxins contained in kaolin clay.
