摘要: 采用静态急性毒性试验研究了3种常用水产用药物对河川沙塘鳢(Odontobutis potamophila)幼鱼24、48、72 h半数致死质量浓度ρ(LC50)(95%置信区间)以及安全质量浓度(SC)。结果表明,10%聚维酮碘对河川沙塘鳢幼鱼24、48、72 h的半数致死质量浓度ρ分别为1466、1148、997.6 mg/L,安全浓度为270.0 mg/L;40%辛硫磷对河川沙塘鳢幼鱼24、48、72 h的半数致死质量浓度ρ分别为4.030、1.207、0.409 mg/L,安全浓度为0.1085 mg/L;4.5%高效氯氰菊酯对河川沙塘鳢幼鱼24、48、72 h的半数致死质量浓度ρ分别为3.007、2.695、0.9740 mg/L,安全浓度为0.7246 mg/L。

Abstract: In order to study toxic effect of several common fish drugs on Odontobutis potamophila juveniles,static bioassays were conducted.Results showed that the24,48 and72 h ρ(LC50) of10% povidonum-iodum (PVP-I) to the fish with95% confidence interval was estimated to be1466,1148,997.6 mg/L,respectively,with the safe concentration being270.0 mg/L.Results show that the24,48 and72 h ρ(LC50) of40% phoxim to the fish with95% confidence interval was estimated to be4.030,1.207,0.409 mg/L,respectively,with the safe concentration being 0.1085 mg/L.Results showed that the24,48 and72 h ρ(LC50) of4.5% Beta-thermometric (beta-CYP) to the fish with95% confidence interval was estimated to be3.007,2.695,0.974 mg/L respectively,with the safe concentration being 0.7246 mg/L.

Key words: beta-thermometric, phoxim, povidonum-iodum, Odontobutis potamophila juveniles, toxic effect
