汞、镉、锌和锰对日本对虾仔虾的急性毒性
Acute Toxicity of Hg, Cd, Zn and Mn to Postlarvae of Penaeus japonicus Bate
【摘要】 在恒温(28±0.5℃)和充气条件下,研究了Hg2+、Cd2+、Zn2+、Mn2+对日本对虾仔虾的急性致毒效应.结果表明,Hg2+、Cd2+、Zn2+、Mn2+对日本对虾仔虾的毒性顺序为Hg2+>Cd2+>Zn2+>Mn2+.根据重金属对日本对虾仔虾的96hLC50值计算的Hg2+、Cd2+、Zn2+、Mn2+的安全浓度分别为0.0012、0.0342、0.0449、0.0950mg/dm3.
【Abstract】 The effects of acute toxicity of Hg2+, Cd2+, Zn2+ , Mn2+ under the condition of aeration postlarvae of Penaeus japonicus Bate have been studied at the temperature of 28±0.5℃. The results show that the order of toxicity of Hg2+, Cd2+ , Zn2+, Mn2+for postlarvae is Hg2+>Cd2+ >Zn2+>Mn2+. The "safe level" of Hg2+, Cd2+ , Zn2+ , Mn2+ to the larvae is 0. 0012, 0. 0342, 0. 0449, 0. 0950 mg/dm3 on the basis of the 96h LC50 value calculated for postlarvae.
