| 摘 要： | 采用静水生物法、充气和恒温法研究Hg2＋对克氏原螯虾（Porcambams darkia Girard）、麦穗鱼（Pseudorasbora parva）、中华绣皱鱼（Rhodem sinemis）3种水生动物的急性毒性作用，结果表明：Hg2＋对中华鲚鲮鱼毒性相对较强，对克氏原螯虾毒性相对较弱；24h对中华螃皱鱼、麦穗鱼、克氏原螫虾的半致死浓度分别为0．222mg／L、0．300mg／L、18．390mg／L，96h对中华螃皱鱼、麦穗鱼、克氏原螯虾的半致死浓度较低，分别为0．193mg／L、0．244mg／L、1．430mg／L。安全质量浓度依次分别为O．00193mg／L、0．00244mg／L、0．01430mg／L；克氏原螯虾对水中H矿离子的耐受性超过国家规定的水质标准28倍多。

| Abstract: | The acute toxicity of Hg2+ to Porcambarus clarkia Girard,Pseudorasbora parva,Rhodens sinensis was determined in still increasing-air water at constant temperature. The results indicated that the 24h LC50 and 96h LC50 to Rhodens sinensis,Pseudorasbora parva,Porcambarus clarkia Girard were 0.222mg/L、0.300mg/L、18.390mg/L and 0.193mg/L、0.244mg/L、1.430mg/L respectively;safe concentration were 0.001 93mg/L、0.002 44mg/L、0.014 3mg/L;tolerance concentation of Porcambarus clarkia Girard to Hg2+ was 28 times more than the water quality standards. |
