摘要: 为研究黄金鲫对铜(Cu2+)、锌(Zn2+)和铬(Cr6+)3种重金属离子的耐受性,试验分别设定不同浓度梯度的重金属离子处理组, 进行急性毒性试验。结果表明,Cu2+半致死浓度(LC50)在24、48、72 h分别为2.63、0.80、0.73 mg/L,安全浓度(SC)为0.022 mg/L。Zn2+和Cr6+在24、48、72、96 h的LC50分别为72.74、59.75、58.05、57.80和519.05、391.05、375.53、347.03 mg/L,二者的SC依次为12.040和66.660 mg/L。3种重金属对黄金鲫的毒性大小依次为Cu2+>Zn2+>Cr6+

Abstract: In order to study the tolerance of Carassius auratus for heavy metal (Cu2 +, Zn2 + and Cr6 +), acute toxicity experiments of heavy metal groups with different concentration gradients were designed. The results show that the LC50 of Cu2+ solution at 24, 48, 72 h were 2.63, 0.80, 0.73 mg/L, respectively, while SC was 0.022 mg/L. The LC50 of Zn2 + and Cr6 + at 24, 48, 72 and 96 h were 72.74, 59.75, 58.05, 57.80 and 519.05, 391.05, 375.53, 347.03 mg/L, respectively, while SC of Zn2 + and Cr6 + were 12.040 and 66.660 mg/L, respectively. The toxicity of the three heavy metal for Carassius auratus was Cu2+>Zn2+>Cr6+.

Key words: Cu2+, Zn2+, Cr6+, Carassius auratus, acute toxicity
