摘要
在实验室条件下,以静水生物测试法研究了十二烷基苯磺酸钠(LAS)和孔雀石绿对泥鳅(Misgurnus angullicaudatus)的单一及联合毒性;同时采用Marking相加指数法对联合毒性进行了评价。结果表明,在单一急性毒性试验中,LAS在24、48、72、96h的半致死浓度(LC50)为22.470、20.408、19.364、18.698mg/L,其安全浓度(SC)为5.050mg/L;而孔雀石绿LC50为2.532、2.247、1.961、1.682mg/L,SC为0.531mg/L。孔雀石绿和LAS均为高毒级,且孔雀石绿的毒性大于LAS。孔雀石绿-LAS联合作用24、48、72、96h的AI值分别为0.015、0.036、0.041、0.152,均大于0,呈现出协同作用,并且随着时间的增加,协同作用增强。
In the experimental condition,the single and joint toxicity of LAS(Sodium dodecyl benzene)and malachite green on Misgurnus angullicaudatus was studied.the joint toxicity was evaluatedwith Marking s additive index.The LC50 of LAS at 24,48,72 and 96 h and its safety concentration were 22.470,20.408,19.364,18.698 and 5.050 mg/L,respectively.LC50 of malachite green were 2.532、2.247、1.961、1.682 and 0.531mg/L;The joint toxicity test indicated that the AI of LAS and malachite green joint action at 24,48,72 and 96 ...
