Acute toxicity of Cu2+ to Rana chensinensis tadpole

Abstract

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℃.
