摘　　要：在水温(20±1)℃下,采用静水试验法研究了聚维酮碘、强氯精和高效氯氰菊酯3种常用水产药物对体长(118.8±5.63)mm、体质量(72.75±15.11)g松荷鲤(Cyprinus carpio Songhe)的急性毒性试验。结果显示,聚维酮碘对松荷鲤的24、48、72、96 h半致死浓度分别为870.551、790.650、694.959、654.692 mg/L,安全质量浓度为195.653 mg/L;强氯精对松荷鲤的24、48、72、96 h半致死浓度分别为23.076、19.608、15.674、13.871 mg/L,安全质量浓度为4.247 mg/L;高效氯氰菊酯对松荷鲤的24、48、72、96 h半致死浓度分别为4.620、2.216、1.205、0.847 mg/L,安全质量浓度为0.153 mg/L。3种药物对松荷鲤的毒性大小为高效氯氰菊酯>强氯精>聚维酮碘。根据有毒物质对鱼类毒性的评价标准,结果表明聚维酮碘和强氯精对松荷鲤为低毒药物,可作为生产中的首选药物;高效氯氰菊酯对松荷鲤为高毒药物,在生产中需谨慎使用。The acute toxicity of povidone iodine,trichloroisocyanuric acid,and lambda-cyhalothrin on Cyprinus carpio Songhe[(118.8±5.63)cm in length,(72.75±15.11)g in body mass]was investigated at a water temperature of(20±1)℃ using a static bioassay method.The results revealed that the median lethal concentration(LC 50)of povidone iodine was 870.551 mg/L at 24 h,790.650 mg/L at 48 h,694.959 mg/L at 72 h,and 654.692 mg/L at 96 h,with a safe concentration of 195.653 mg/L.For trichloroisocyanuric acid,the LC 50 was 23.076 mg/L at 24 h,19.608 mg/L at 48 h,15.674 mg/L at 72 h,and 13.871 mg/L at 96 h,with a safe concentration of 4.247 mg/L.The LC 50 of lambda-cyhalothrin was 4.620 mg/L at 24 h,2.216 mg/L at 48 h,1.205 mg/L at 72 h,and 0.847 mg/L at 96 h,with a safe concentration of 0.153 mg/L.The descending order of toxicity among the three substances to C.carpio Songhe was lambda-cyhalothrin>trichloroisocyanuric acid>povidone iodine.Based on toxicity evaluation criteria,povidone iodine and trichloroisocyanuric acid exhibited low toxicity for C.carpio Songhe and could be considered as the preferred choices in practical applications.However,lambda-cyhalothrin demonstrated high toxicity for C.carpio Songhe,requiring careful consideration and cautious use in practice.
