英文摘要	近年来,中国近岸重金属污染问题日趋严重。作者通过研究重金属Cd~（2＋）和Pb~（2＋）对脊尾白虾（Palaemon carincauda）的单一及复合急性毒性效应,为其养殖水质管理提供科学依据。本研究采用半静态急性毒性测定方法,开展了不同浓度Cd~（2＋）和Pb~（2＋）对脊尾白虾96 h内的急性毒性试验。研究结果表明：在单一污染物暴露下,Cd~（2＋）对脊尾白虾24、48、72、96 h的半数致死质量浓度（LC50）分别为138.699、33.110、9.719、3.650 mg/L,Pb~（2＋）对脊尾白虾48、72、96 h的LC50分别为254.541、62.750、29.074 mg/L;Cd~（2＋）、Pb~（2＋）对脊尾白虾96 h的安全质量浓度分别为0.365和2.907 mg/L;在等浓度配比（1︰1）暴露下,Cd~（2＋）和Pb~（2＋）复合污染对目标生物在48、72、96 h暴露期间的毒性相加指数（additive index,AI）分别为0.155、0.068、0.258。综上所述,Cd~（2＋）对脊尾白虾的毒性较Pb~（2＋）更强,Cd~（2＋）和Pb~（2＋）对脊尾白虾的复合污染均表现出较明显的协同作用。
中文摘要	The presence of heavy metals in the coastal environment has been of great concern due to their non-biodegradable nature. This study aims to investigate single and joint acute toxic effects of Cd2＋ and Pb2＋ on Palaemon carincauda and provides the basis for the water quality management of aquaculture. The effects of dif-ferent concentrations of Cd2＋ and Pb2＋ on P. carincauda within 96 h were investigated by using the semistatic acute toxicity test. The results showed the following：（1） The 24, 48, 72 and 96 h median lethal concentrations （LC50） of Cd2＋ on P. carincauda were 138.699, 33.110, 9.719 and 3.650 mg/L, respectively, and the 48, 72 and 96 h LC50 of Pb2＋ were 254.541, 62.750 and 29.074 mg/L, respectively. The 96 h safety concentrations （SC） of Cd2＋ and Pb2＋ on P. carincauda were predicted to be 0.365 mg/L and 2.907 mg/L, respectively; （2） At a concentration ratio of 1︰1, the additive index values for Cd2＋ and Pb2＋ were 0.155, 0.068, and 0.258 during the experiment time of 48, 72 and 96 h, respectively. These results indicated that Cd2＋ presented higher toxicity toward the shrimps than Pb2＋. Joint toxic effects of Cd2＋ and Pb2＋ demonstrated synergistic effects during the experimental period.
