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。
以半滑舌鰨(Cynoglossus semilaevis Gunther)為研究對象進行96 h的急性毒性試驗,探究甲醛和硫痠銅處理後半滑舌鰨的半數緻死濃度(LC50)和安全濃度(SC )。實驗結果錶明,甲醛處理48 h、96 h後半滑舌鰨的LC50分彆為375.68 mg · L -1、351.74 mg · L -1,SC為35.174 mg · L -1;硫痠銅處理48 h、96 h後LC50分彆為2.81 mg · L -1、2.58 mg · L -1,SC為0.258 mg · L -1。
