为进一步了解有机氯农药（OCPs）的生物富集规律，反映不同渔业环境中OCPs的富集状况，对淡水养殖、海水养殖和海水野生3种不同渔业类型的鱼类组织进行了分析。在海水养殖鱼类和三种淡水养殖鱼类中发现了显著较高的Sigma OCP水平。滤食性鱼类（鳙鱼）体内的浓度水平最低。肝脏含有最高的Sigma OCP水平。而阴离子、其它组织间无显著差异。海水鱼中p，p '-DDT含量最高，淡水鱼中p，p'-DDE含量最高，但北方黑鱼中p，p '-DDE和p，p'-DDT的含量分别为34%和30%。淡水鱼塘的新滴滴涕来源部分是三氯杀螨醇，而珠江三角洲排放的污水和防污漆可能是海水养殖鱼类的滴滴涕来源。(C)2007爱思唯尔有限公司版权所有。
Fish tissues from different fishery types (freshwater farmed, seawater farmed and seawater wild) were analyzed for organochlorine pesticides (OCPs), with the aim to further our understanding of bioaccumulation, and reflect the state of different fishery environments. Significantly higher Sigma OCP levels were found in seawater farmed fish than others, and among three freshwater farmed species. the lowest levels occurred in filter-feeding fish (bighead carp). Liver contained the highest Sigma OCP levels. while no significant differences were found anion, other tissues. Among DDT components, p,p'-DDT was abundant in seawater fish, while for freshwater fish, p,p'-DDE was the predominant congeners, except for northern snakehead (34% for p,p'-DDE and 30% for p,p'-DDT). The new Source of DDTs to freshwater fish ponds was partly attributed to dicofol, whereas sewage discharged from the Pearl River Delta and anti-fouling paint were likely the DDTs sources to seawater farmed fish.
