Ten dog sharks (Mustelus griseus) collected from Zhoushan Fishing Ground, China, were analysed for organochlorine pesticides in various tissues, including muscle, liver, skin, gill and fin, with the aim to study the residues, sources and tissue distributions of these chemicals in high trophic level marine fishes. The concentrations of DDTs, HCHs, and chlordanes varied from 7.27-26.62, 2.67-3.35, and 0.54-0.61 ng/g wet weight, respectively, with the estimated daily intake far below the acceptable daily intake and Chinese edible hygienic criteria. Data from the tissue distribution suggested a tendency of DDTs and chlordanes to accumulate in the liver, but for HCHs, direct gill penetration may be an important means of entrance. In addition, the compositional profiles indicated that the residues of HCHs and chlordanes mainly originated from the historical usage of these chemicals. However, the predominant maternal compounds and the o,p'-DDT/p,p'-DDT ratios reflected a recent use of dicofol.
从中国舟山渔场采集了 10 条狗鲨（Mustelus griseus），分析了其肌肉、肝脏、皮肤、鳃和鳍等各种组织中的有机氯农药，旨在研究这些化学物质在高营养级海洋鱼类中的残留、来源和组织分布。DDTs、HCHs 和氯丹的浓度分别为 7.27-26.62、2.67-3.35 和 0.54-0.61ng/g 湿重，估计日摄入量远低于可接受日摄入量和中国食用卫生标准。组织分布数据表明，DDTs 和氯丹有在肝脏中积累的趋势，但对于 HCHs，直接通过鳃渗透可能是一种重要的进入途径。此外，组成谱表明 HCHs 和氯丹的残留主要来源于这些化学物质的历史使用。然而，主要母体化合物和 o,p'-DDT/p,p'-DDT 比值反映了近期使用了三氯杀螨醇。
