摘要
研究了铜和镉对蝌蚪的急性毒性和联合毒性。结果表明,Cu2+对蝌蚪的24h、48h、96h的LC50分别为0.201、0.138和0.118mg/L;Cd2+对蝌蚪的24h、48h和96h的LC50分别为32.1、23.3和18.9mg/L。Cu2+和Cd2+共存对蝌蚪的24h、48h和96h联合毒性相加指数(AI)分别为1.03、1.12和1.20。
Synergetic toxicity of copper and cadmium to tadpole has been studied with acute tests. The result showed that LC50 of Cu2+ to tadpole were 0.201, 0,138 and 0.138mg/L in 24h, 48h and 96h respectively. LC50 of Cd2+ to tadepole were 32.1, 23.3 and 18.9mg/L in 24h, 48h and 96h respectively. The synergetic toxicity of Cu2+ and Cd2+ to tadpole in 24h, 48h and 96h addictive index were 1.03, 1.02 and 1.20 in 24h, 48h and 96h respectively.
