在日本海南部至北海道的4个地区和日本等地采集了马苏鲑2个亚种：Oncorhynchus masou masous。masou ishikawa从伊势湾上游靠近一个重工业地区。采用HRGC/HRMS对209个PCB同源物进行分析。同系物浓度PCA排序将数据分为三组：(i) ssp。来自北海道的masous， （ii） ssp。从其他区域和（iii） ssp。ishikawae。∑PCB浓度最高的是ssp （40.39 ng/wet wt）。石川后面跟着ssp。马苏来自南部水域；而teq二恶英样多氯联苯在ssp中含量最高。由于同族体#126在其补体中所占比例很高（#126在同族体中毒性等效系数最高），来自南方水体的马苏木（1.96 pg- teq二恶英样多氯联苯/g湿wt.）。在日本海南部的近海和/或沿海象的迁徙路线可能有一个污染源。
We collected two subspecies of masu salmon:Oncorhynchus masou masoufrom four localities (southern Sea of Japan northward to Hokkaido) andO. masou ishikawaefrom upstream from Ise Bay close to a heavy industrial area. All 209 PCB congeners were analyzed using HRGC/HRMS. PCA ordination of congener concentrations divided data into three groups: (i) ssp.masoufrom Hokkaido, (ii) ssp.masoufrom the other regions and (iii) ssp. ishikawae. The highest ∑ PCB concentration (40.39 ng/wet wt) was in ssp.ishikawaefollowed by ssp.masoufrom southern waters; however the TEQdioxin-like PCBswas highest in ssp.masoufrom southern water (1.96 pg-TEQdioxin-like PCBs/g wet wt.) due to the high proportion of congener #126 in its complement (#126 has the highest toxic equivalency factor among congeners). There is likely a contamination source offshore in the southern Sea of Japan and/or along the migratory route of ssp.masou.
