摘　　要：用生物检验法研究了苯胺、苯酚对蛋白核小球藻、斜生栅藻生长的影响,测定了两种藻类在5d内对不同浓度苯胺、苯酚的降解或在藻细胞内的富集情况.结果表明,苯胺、苯酚对两种淡水藻类的致毒作用有所不同,对于同一种藻类,苯胺毒性大于苯酚;在同一毒物浓度下,栅藻表现更为敏感.在较低浓度下,两种淡水藻类均能降解或吸收一部分有机毒物,其中对苯酚的降解能力较强.By the methods of bioassay, this paper studied the effects of aniline or phenol on the growth of Chlorella pyrenoidosa and Scenedesmus obiquus. The results showed that these two compounds had evident effects on the growth of test algae species. For the same species, aniline was more toxic. Under the same concentration of the compounds, S. obiquus was more sensitive than C.pyrenoidosa. These two algae species could degrade or absorb parts of the compounds, and phenol in particular, when their concentrations were lower.
