苯胺是农药,染料和医药工业的重要原料,被列为环境优先控制污染物之一。藻类在水体食物链申起重要作用。本文研究了苯胺对无菌衣藻、裸藻、聚球藻和硅藻四种淡水藻类的96h半数抑制浓度 EC50值,衣藻的为70mg/L,裸藻为45mg/L,硅藻为6.3mg/L,聚球藻为1.0mg/L,得到其耐受性大小为:衣藻 】裸藻】硅藻】聚球藻。同时通过肉眼和显微观察,发现这四种藻在颜色和形态上均受到不同程度的影响,此结果对探明苯胺对藻类的生态毒理效应具有重要意义。

Aniline is used in a number of manufacturing processes, which is recognized as a serious environmental contamination and is marked as one of the priority pollutants. The toxic effects of aniline on the four freshwater algae were investigated. The results showed that the concentration for 50% reduction (EC50) of aniline in the four species of freshwater algae (C.reinhardtii, E.gracilis, N.pelliculosa, S.leopoliensii) were 70mg/L, 37mg/L, 6.3mg/L, 1.0mg/L after culturing 96h at 25±1℃, respectively. The susceptibility of the four freshwater alga...
