Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) ranging from tetra- to octachloro congeners in ash and fly ash from incinerators, river water, effluent water from incinerators, groundwater, soil, and sediment were determined isomer specifically by high-resolution gas chromatograph-mass spectrometry in order to manifest an environmental situation polluted with those compounds in Japan. The most toxic 2,3,7,8-tetrachlorodibenzo-p-dioxin was detected only in fly ash. In many samples, octachlorodibenzo-p-dioxin had the highest abundance in PCDDs, and heptachlorodibenzofurans had the highest abundance in PCDFs. Gas chromatographic patterns of PCDDs and PCDFs in all samples were compared with each other by use of the pattern similarity method in order to classify the pollution pattern with PCDDs and PCDFs. Gas chromatographic patterns of PCDDs and PCDFs in fly ash, effluent water, and sediment were different from each other.
