| 摘 要： | LowerFoxRiver和LowerGreenBy水域的沉积物造成了该地区的轻度污染。经测定和分析，沉积物中含有较高的PCBs和较低含量的PCDFs及PCDDs，在鱼样品中呈现有PCBs和农药。组织病理学检查，鱼体内寄生虫感染发生率较高，部分肝组织坏死，出现肉芽瘤状物，胰腺纤维化，但没有发现鱼体上有肿瘤。

| Abstract: | The sediment in Lower Fox River and Lower Green Bay caused a little degree of pollution. The results of the paper suggested that the concentration of PCBs washigher while the concentration of FCDF and PCDDs were lower in sediments.Moreover, there were PCBs and pesticides in fish sampled from each collected site.Examinations with histopathological method indicated that the infection rate with parasites in fish is high; Meanwhile, necrotic tissue and granuloma were found in liver,fibrous area in pancreas appeared but tumor was not found in the fish. |
