中文摘要：

以半滑舌鳎（Cynoglossus semilaevis Gunther）为研究对象进行96h的急性毒性试验,探究甲醛和硫酸铜处理后半滑舌鳎的半数致死浓度（LC50）和安全浓度（SC）。实验结果表明,甲醛处理48h、96h后半滑舌鳎的LC50分别为375.68mg·L-1、351.74mg·L-1,SC为35.174mg·L-1;硫酸铜处理48h、96h后LC50分别为2.81mg·L-1、2.58mg·L-1,SC为0.258mg·L-1。

Abstract. Taking Cynoglossus semilaeuis Gunther in acute toxicity test is conducted on 96h, formalde- hyde and copper sulfate treatment second half of Cynoglossus semilaeuis lethal concentration （LCs0） and safe concentration （SC）. The experimental ment of LC50 were 375.68 mg ·L^-1 mg and 351. treatment 48h, 96h of LC50 were 2.81 mg ·L^-1 results show that, 48h, 96h after formaldehyde treat- 74mg·L^-1 ,SCwas35.174mg ·L^-1 copper sulfate and 2.58 mg·L^-1 , SCwas0.258 mg·L^-1
