Coastal and marketing fishes in Japan were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and coplanar PCBs (Co-PCBs) at limits of determination of 0.01-0.1 ppt (pg/g) on wet weight basis in the selected ion monitoring method by using high resolution GC/MS (R=7000-10000). Highly toxic 2, 3, 7, 8-substituted PCDD and PCDF isomers (2, 3, 7, 8-PCDDs and 2, 3, 7, 8-PCDFs) were detected in all fish samples examined. The total concentrations of 2, 3, 7, 8-PCDDs and 2, 3, 7, 8-PCDFs were respectively 1.60-4.3 and 2.40-7.6 ppt in coastal fishes, and 0.04-1.50 and 0.01-3.7 ppt in marketing fishes. It was first clarified that all analyzed fish samples were also polluted by toxic Co-PCBs at levels of 290-1500 and 0.40-170 ppt in coastal and marketing fishes, respectively. On the other hand, 2, 3, 7, 8-T4 CDD toxic equivalent (TEQ) levels of PCDDs and PCDFs were calculated by international toxicity equivalency factor (I-TEF), and that of Co-PCB by TEF reported by Hanberg et al. The total TEQ levels of PCDDs/PCDFs in coastal and marketing fishes were 0.63-1.41 ppt (mean±S.D. : 0.87±0.28 ppt) and <0.01-0.86 ppt (0.33±0.25 ppt), respectively. In addition, average TEQ levels of Co-PCBs in coastal and marketing fishes were 9.4±7.3 and 0.22±0.24 ppt, respectively. It is noteworthy that the TEQ level of Co-PCBs in coastal fish was greater than that of PCDDs or PCDFs.
