摘　　要：目的 评价污水养殖鱼的细胞遗传毒理学安全性。方法 用小鼠骨髓细胞微核试验对采自天津市南、北排污河流域污水养鱼池的污养鱼肉有机提取物进行致突变性检测。结果 本次采集的3组污养鱼肉有机提取物均呈致突变阳性结果,而清养鱼有机提取物呈致突变阴性结果。结论 污水养殖鱼体内含有有机致突变物质,这些物质会通过食物链进入人体,可能对人群健康产生潜在危害。ve To assess the cytogenetic toxicological safety of fish raised in water containing effluent. Methods The mutagenecity of organic extracts of uncooked meat specimens of fish raised in fishpond water mixed with sewage water taken from South and North Sewer Drainage Canals of Tianjin was detected by mice bone marrow micronucleus test. Results The organic extracts of uncooked fish meat specimens showed positive result for all of the 3 observed groups of fish raised in water of fish ponds with sewage, and negative result for fish raised in clean fishpond water in micronucleus test. Conclusion The results indicated that some kinds of organic mutagenic compounds ex-isted in the uncooked meat of fish raised in fishpond water containing effluent, which might have some potentially hazardous effects on human health through the food chains.
