PCBs and OCPs were analyzed in fish (bass) taken along Chinese coastal fisheries. In the bass muscle, PCB, DDT and HCH concentrations were in the range of 1.02-2.2ng/g, 0.44-1.74 and 2.84-106.11ng/gww, respectively. Spatial distribution showed that the concentrations of target contaminants in bass from south fisheries were in general much lower than those from north fisheries in China. The ratios of OCP congeners suggested that technical DDT was not the main input and a recent usage of lindane or old technical HCH residuals could be the source of HCHs. The OCC concentrations in liver (127-442.43ng/gww) from selected samples were 8-12 and 10-14 times higher than those in gills and muscles, respectively. Based on the maximum allowable fish assumption rate (CRlim and CRmm), it could cause human health risk, by consuming bass samples taken from highly contaminated fisheries including QD and ST.
对取自中国沿海渔场的鱼类（鲈鱼）进行了多氯联苯（PCBs）和有机氯农药（OCPs）分析。在鲈鱼肌肉中，多氯联苯、滴滴涕（DDT）和六氯环己烷（HCH）的浓度分别在1.02 - 2.2纳克/克、0.44 - 1.74纳克/克和2.84 - 106.11纳克/克湿重范围内。空间分布表明，中国南方渔场鲈鱼体内目标污染物的浓度总体上远低于北方渔场。有机氯农药同系物的比例表明，工业用滴滴涕不是主要输入源，林丹的近期使用或旧的工业用六氯环己烷残留可能是六氯环己烷的来源。所选样本肝脏中的有机氯化合物浓度（127 - 442.43纳克/克湿重）分别比鳃和肌肉中的高8至12倍和10至14倍。根据最大允许鱼类假设率（CRlim和CRmm），食用取自包括青岛（QD）和汕头（ST）在内的高污染渔场的鲈鱼样本可能会对人类健康造成风险。
