摘要：

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. (C) 2013 Elsevier Ltd. All rights reserved.
