In 2014-2019, a total of 31 blubber samples were collected from spotted seals (Phoca largha) in the western Sea of Japan. The samples were analyzed by gas chromatography to determine level of organochlorine pesticides (OCPs). The concentration of hexachlorocyclohexane and its isomers (∑HCH) ranged from 389 to 50,070 ng/g lipid weght; the concentration of dichlorodiphenyltrichloroethane and its metabolites (∑DDT), ranged from 62,720 to 1,110,930 ng/g lipid wt. Transfer of HCH and DDT from mother to pup during pregnancy and lactation was documented. The OCP concentration in blubber of spotted seals from the western Sea of Japan is one to two orders of magnitude higher than in spotted seals inhabiting waters off the Japan coast. Organochlorines detected in the western Sea of Japan likely come from some countries of Southeast Asia still using OCPs in the agriculture sector.
2014-2019 年，从日本海西部的斑海豹（Phoca largha）身上采集了 31 个鲸脂样本。通过气相色谱法对这些样本进行了分析，以确定有机氯农药（OCPs）的水平。六氯环己烷及其异构体（∑HCH）的浓度范围为 389-50070ng/g 脂肪重量；二氯二苯三氯乙烷及其代谢物（∑DDT）的浓度范围为 62720-1110930ng/g 脂肪重量。记录了 HCH 和 DDT 在妊娠和哺乳期从母海豹到幼崽的转移情况。日本海西部斑海豹的 OCP 浓度比栖息在日本沿海水域的斑海豹高出一到两个数量级。日本海西部检测到的有机氯可能来自一些仍在农业部门使用 OCPs 的东南亚国家。
