摘要: 试验测定了不同温度条件下Cu2+对中国林蛙蝌蚪的急性毒性。结果表明,在水温为9~13℃、18℃和24℃条件下,Cu2+对10d龄中国林蛙蝌蚪96h的LC50分别为5.01、3.80和2.99mg·L-1, 致死阈浓度分别为4.0、2.5和1.6mg·L-1, 而在96h内的无可观察效应浓度分别为2.5、1.6和1.0mg·L-1.18℃条件下Cu2+对20d龄中国林蛙蝌蚪的96hLC50为2.17mg·L-1.

Abstract: The acute toxicity of Cu2+ to Rana chensinensis tadpole was determined under various water temperature. The results showed that, at 9~13, 18 and 24℃, its 96h LC50for 10 days old tadpole was 5.01, 3.80 and 2.99mg·L-1, respectively. The lethal concentration, was 4.0, 2.5 and 1.6mg·L-1, and the no observed effect concentration(NOEC) in96hours was 2.5, 1.6 and 1.0mg·L-1, respectively. The 96h LC50 for 20 days old tadpole was 2.17mg·L-1 at 18℃.
