摘　　要：目的实验室评价密达利对淡水鱼类的毒性。方法采用ISO7346-2试验方法观察密达利对斑马鱼、鲤鱼苗、中华绒螯蟹、日本沼虾、三角帆蚌、河蚬等淡水生物的毒性。结果密达利对斑马鱼、鲤鱼苗、中华绒螯蟹、日本沼虾、三角帆蚌、河蚬安全浓度分别为11.9、18.1、18.7、10.5、82.7mg/L和62.0mg/L。结论密达利对常见淡水鱼类的毒性均属于低等毒性。Objective To evaluate the toxicities of Meta-li against freshwater fish in laboratory.Methods An acute toxicity test of Meta-li was conducted to determine its acute lethal toxicity to freshwater fish,crab,and shrimp in laboratory by using the method of ISO 7346-2.Results The safe concentrations of Meta-li to the Brachdanio rerio,Cyprinus carpio,Eriochier sinensis,Macrobrachium nipponense,Hyriopsis cumingii and Corbicula fluminea were 11.9、18.1、18.7、10.5、82.7 mg/L and 62.0 mg/L,respectively.Conclusion The acute lethal toxicity of Meta-li to freshwater fish is low.
