摘    要:应用斜生栅列藻作为生物指示物,对16种重金属化合物的单一毒性进行毒性评价,并分别从微观和宏观角度分析了重金属的致毒机理。实验结果表明:它们的毒性大小顺序为Ag+Cd2+Cu2+Zn2+Sr2+Pb2+Hg2+Sn4+Al3+Cr+Ni2+Mn2+Ba2+Fe3+Co2+Li+。

关 键 词:重金属化合物  斜生栅列藻  急性毒性

Abstract:In the present study,scenedesmus obliquus was used to indicate and evaluate the acute toxicity of 16 heavy metals.The results showed that the hierarchy of metal toxicity was Ag+>Cd2+>Cu2+>Zn2+>Sr2+>Pb2+>Hg2+>Sn4+> Al3+>Cr+>Ni2+> Mn2+>Ba2+>Fe3+>Co2+> Li+.The toxic mechanism of the heavy metals was analyzed from microcosmic aspect and macroscopical angle respectively.
Keywords:heavy metal compound  scenedesmus obliquus  acute toxicity
