为阐明松花江鱼体中有机毒物是否有潜在的致癌性,我们对沿江居民历年摄食的主要鱼种的有机提取物进行了致突变性实验研究。 鱼的来源与贮存:实验用鱼是1982年5月捕自松花江肇源江段的鲤鱼、鲫鱼和鲶鱼,体重分别为0.5～1.5公斤,0.25～0.5公 In order to elucidate the potential carcinogenicity of organic poisons in the fish body of the Songhua River, we conducted an experiment on the mutagenicity of the organic extracts of the main species of fish that had been consumed by the residents along the river for many years. Source and storage of fish: experimental fish was caught in May 1982 from the Songhua River Zhaoyuan Jiang carp, crucian and catfish, weighing 0.5 to 1.5 kg, respectively, 0.25 to 0.5 public
