Dioxins (polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and dioxin-like polychlorinated biphenyls) in ash residue taken from 59 small-sized incinerators placed at facilities such as schools in Saitama prefecture, which had not been used since 1997, were determined. The range of dioxin toxic equivalent (TEQ) was 0.0019-18 ng-TEQ/g, and TEQ of dioxins in 10 of 59 ash samples exceeded the landfill standard (3 ng-TEQ/g).
