Summary: The Special Measures Law on Dioxin Control was enacted in 1999 from the viewpoint that dioxin control measures had to be taken urgently in Japan, and the target value for fly ash was set at 3 ng TEQ/g I). To comply with this law, over fifty municipal governments introduced a low-temperature (below 400 deg. C.) treatment of fly ash under oxygen-deficient condition (i.e. the Hagenmaier process 2); the HM process) for dechlorination of dioxins. The aim of this study is to confirm the reduction of dioxin-like activity of fly ashes treated by the HM process by cell-based bioassay measurement of Ah-R dependent activity as DR-CALUX® and the feasibility of monitoring during the HM process by the cell-based Ah receptor bioassay.
