Abstract：
:Ash samples collected from medical, municipal and small-scale domestic incinerators in Japan were tested for dioxin-like activity using bioassay technique (ethoxyresorufin-O-deethylase: EROD assay) and for extractable organohalogens (EOX) using instrumental neutron activation analysis in order to estimate potential toxicity and responsible chemicals in those samples. Crude extracts and fractions cleaned-up for dioxin analysis from the samples were used for the analysis. The ranges of dioxins in the ashes were between 2.23 and 12.29 ng TEQ/g (dry weight). Relative potency ranges estimated by EROD assay in the medical incinerator ashes were 3.8-17.6 times higher than the results of conventional chemical analysis. EOX analysis suggested that ash samples contained plenty of organochlorine compounds apart from chlorinated dioxins. In addition, medical waste incinerator ashes were considered to have relatively higher amount of organoiodine compounds. In the cleaned-up fractions, bioassay potency ranges were lower than those in the crude extracts. However, some samples still exhibited higher potency than expected from chemical analysis. Though some polycyclic aromatic hydrocarbons were found in the fractions, the amounts were relatively low (0.39-10.56 ng/g). The results imply that some bioactive organohalogens that cannot be detected in the conventional chemical analysis might have potential for dioxin-like toxicity, and contribute to higher bioassay activities. The combination of the chemical analysis with the bioassay and EOX provides rough figure of dioxin-like toxicity and suggests types of organohalogen compounds that should be identified as a part of dioxin analysis for control emission from an incineration plant.
