摘　　要：本文采用评价化学品对藻类毒性的标准实验方法,研究了1-硝基芘(1-NP)对斜生栅藻生长的影响,得到了1-NP抑制斜生栅藻生长的EC_(50)(96h)为0.1824mg·1^(-1),实验结果还表明,1-NP对藻生长的抑制作用随时间的延长而增加,抑制特性表现为持久且强度大,抑制机理为不可逆性抑制。Toxicity effects of 1-nitropyrene on Scenedesmus Obliquus K utz were researched according to the standard experiment method for algae toxicity of chemicals. Result showed the repressive effect on Scenedesmus Obliquus Kutz growing -EC50 (96h) is 0. 1824mg · 1-1, moreover, it showed that the repressive effect is more and more enganced along with time, the characteristic of the repressive effect is lasting and houghtly, and the repressive mechanism is inreversible repession.
