贵州滥木厂废渣浸出液对隆线溞的生物毒性实验研究

Study on the biotoxicity to Daphnia carinate with waste residue's leachate from Guizhou Lanmuchang

本文通过对贵州滥木厂废渣进行不同酸雨条件下的浸取实验,用其浸出液对隆线溞进行急性生物毒性实验。实验结果表明:pH为5、5.5及6、6.5其96h对隆线溞的半致死体积分数LC50分别为3.4914%、2.3883%、1.5222%、2.0850%,说明此废渣浸出液有很强的生物毒性。

The study investigated leaching toxicity and biotoxicity of waste residue to Daphnia earinata with waste residue from Guizhou Lanmuchang under the different acid rain . The result indicated that LC50 （96h） were 3. 4914% （pH5） , 2.3883% （pH5.5）, 1. 5222% （pH6） ,2.0850% （pH6.5） . So its leachate had big acute toieity.
