对从西北太平洋收集的中层蕈鱼中的有机氯 (OC) 和丁基锡 (BT) 残留量进行了测定，以阐明污染状况、积累模式和分布。在 OC 中，蕈类中 PCB（多氯联苯）和 DDT（滴滴涕及其代谢物）的浓度最高（最高浓度分别为 370 ng/g 和 280 ng/g 脂质重量）。 CHL（氯丹化合物）或 HCH（六氯环己烷）是第二丰富的 OC，HCB（六氯苯）含量最低。鱼体内总丁基锡 (ΣBTs = MBT + DBT + TBT) 的最大浓度为 46 ng/g 湿重。海洋蕈螨中的 PCB、CHL 和 BT 浓度显着低于日本骏河湾沿岸水域的鱼类。根据菌蚜的昼夜垂直迁移，OCs 和 BTs 的残留模式显示出特定的趋势。在生活在较深水域的非迁徙物种中发现了相对较高浓度的 PCB、DDT 和 CHL。
Organochlorine (OCs) and butyltin (BTs) residues were determined in mesopelagic myctophid fishes collected from the western North Pacific to elucidate contamination status, accumulation patterns, and distribution. Among OCs, concentrations of PCBs (polychlorinated biphenyls) and DDTs (DDT and its metabolites) were the highest in myctophids (at maximum concentrations of 370 ng/g and 280 ng/g lipid wt, respectively). CHLs (chlordane compounds) or HCHs (hexachlorocyclohexanes) were the next most abundant OCs, and HCB (hexachlorobenzene) was the lowest. The maximum concentration of total butyltin (∑BTs = MBT + DBT + TBT) in fish was 46 ng/g wet wt. Concentrations of PCBs, CHLs, and BTs were significantly lower in oceanic myctophids than those in fishes from Japanese coastal water, Suruga Bay. The residue pattern of OCs and BTs showed a specific trend according to diel vertical migration of myctophids. Relatively high concentrations of PCBs, DDTs, and CHLs were found in nonmigratory species living in deeper wa...
