Even though the use of polychlorinated biphenyls (PCBs) was banned in Japan during the 1970s owing to its highly toxic effects, PCBs are still detected in marine organisms around the Japanese coast. Moreover, unintentionally produced PCB congeners have been detected in air and water in North America. The present study was conducted to investigate the presence of unintentionally produced PCB congeners among salmon and seabass collected from Japan to Southeast Asia by trace analysis for all 209 PCB congeners. About 120 to 160 congeners were detected among these fish. #153 (a dominant conger of technical PCBs) was most dominant among fish along the Japanese coast. #11, a di-chlorinated congener, was detected in high concentrations among barramundi collected from the Strait of Malacca, Malaysia. This congener is thought to be an unintentionally produced PCB congener.

尽管由于多氯联苯的剧毒作用，多氯联苯在20世纪70年代在日本被禁止使用，但在日本海岸周围的海洋生物中仍然检测到多氯联苯。此外，在北美的空气和水中也发现了无意中产生的多氯联苯同系物。本研究通过对所有209种多氯联苯同系物的痕量分析，调查了从日本到东南亚采集的鲑鱼和海鲈中无意产生的多氯联苯同系物的存在。在这些鱼类中检测到约120至160个同系物。#153（技术多氯联苯的主要长度）在日本沿海的鱼类中占主导地位。#11是一种二氯同系物，在马来西亚马六甲海峡采集的澳洲undi中检测到高浓度。这种同系物被认为是无意产生的PCB同系物。
