【摘要】 在水温为(27±0.5)℃,盐度为7°B′e和连续充气条件下,采用动态活水法研究了汞、铅、铜、锰、镉对卤虫无节幼体的毒性效应及联合毒性作用。结果表明,五种金属对卤虫无节幼体的48hLC50分别是0.028、1.31、4.06、12.15、28.91mg/L。毒性由强至弱依次为Hg2+>Pb2+>Cu2+>Mn2+>Cd2+,Hg-Cu,Cu-Mn对卤虫幼体的联合作用表现为拮抗作用,Pb-Cu、Pb-Mn、Mn-Cd则为协同作用。更多还原

【Abstract】 The effects of toxicity and joint toxicity of hydrargyrum,plumbum,cuprum manganese,cadmium to Artemia nauplius were studied at salinity 7°B′e,temperature 27±0.5℃ and inflate using the dynamic living water method.The 48hLC₅₀ of these five heavy metal to the artemia nauplius is0.028?1.31?4.06?12.15?28.91mg/L for artemia nauplius.The order of toxicity of hydrargyrum,plumbum,cuprum manganese,cadmium for artemia nauplius was Hg²⁺>Pb²⁺>Cu²⁺>Mn²⁺>Cd²⁺.Hg-Cu,Cu-Mn are antagonism;Pb-Cu?Pb-Mn?Mn-Cd are synergism.更多还原
