工业废渣种类繁多,成分复杂,其毒性实验研究报道甚少。本实验对砷钙渣和砷铁渣的水浸出液进行了动物急性毒性探索性研究。实验采用100克废渣加1000毫升蒸馏水浸泡,经恒温振荡、静置、过滤,再用蒸馏水配制成不同固液比稀释液,给昆明种小鼠(?)灌胃染毒。结果两种废渣浸出液的急性中毒半数致死量分别为4677.35毫克/公斤和1698.24毫克/公斤。 Industrial waste a wide range of complex components, the toxicity of experimental studies reported little. In this experiment, we studied the acute toxicity of aqueous extracts of arsenic calcium slag and arsenic iron slag. Experiments using 100 g of waste residue plus 1000 ml of distilled water immersion, the constant temperature oscillation, standing, filtered, and then distilled water to prepare different solid-liquid ratio dilution to Kunming mice (?) Gavage. Results The acute lethality of the two kinds of waste leachate were 4677.35 mg / kg and 1698.24 mg / kg respectively.
