以半滑舌鳎(Cynoglossus semilaevis Gunther)为研究对象进行96 h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48 h、96 h后半滑舌鳎的LC50分别为375.68 mg · L -1、351.74 mg · L -1,SC为35.174 mg · L -1;硫酸铜处理48 h、96 h后LC50分别为2.81 mg · L -1、2.58 mg · L -1,SC为0.258 mg · L -1。%Taking Cynoglossus semilaevis Gunther in acute toxicity test is conducted on 96h ,formalde-hyde and copper sulfate treatment second half of Cynoglossus semilaevis lethal concentration (LC50 ) and safe concentration (SC) .The experimental results show that ,48h ,96h after formaldehyde treat-ment of LC50 were 375 .68 mg · L -1 mg and 351 .74 mg · L -1 ,SC was 35 .174 mg · L -1 ;copper sulfate treatment 48h ,96h of LC50 were 2 .81 mg · L -1 and 2 .58 mg · L -1 ,SC was 0 .258 mg · L -1 .
