| 摘 要： | 采用静水生物测试法,研究了汞、铅、锌对高体鳑鲏鱼苗的急性毒性,结果表明:24、48、72、96 h的LC50,Hg2+分别为0.6123、0.4734、0.3921、0.3621 mg/L;Pb2+分别为14.1421、13.7405、13.5261、13.1867 mg/L;Zn2+分别为24.4688、20.3542、19.5449、17.8608 mg/L。Hg2+、Pb2+、Zn2+对高体鳑鲏鱼苗的安全质量浓度分别为0.0362、1.3186、1.7861 mg/L。

| Abstract: | Acute toxicity of Hg2+,Pb2+and Zn2+ to rose bitterling Rhodeus ocellatus fry was studied by static bioassay test.The LC50 of Hg2+ for 24 h,48 h,72 h,and 96 h was found to be 0.6123,0.4734,0.3921,and 0.3621 mg/L for the fry,respectively;LC50 of Pb2+ 14.1421,13.7405,13.5261,and 13.1867 mg/L and LC50 of Zn2+ 24.4688,20.3542,19.5449,and 17.8608 mg/L,respectively.The safety concentrations of Hg2+,Pb2+and Zn2+ were found to be 0.0362,1.3186,and 1.7861 mg/L,respectively. |
