摘要
本文运用评价化学品对藻类毒性的标准实验方法,得出苯酚、邻氯苯酚、2,4-二氯苯酚和五氯酚抑制斜生栅藻生长的96h-EC_(50)分别为341,85,25和1.5mg·l^(-1)。实验结果表明,在300,350和400mg·l^(-1)三种苯酚初始浓度下,斜生栅藻都不具备降解苯酚的能力,即使在培养基中基本没有无机碳源的情况下,斜生栅藻仍不具备降解苯酚的能力。
A standard method of algal bioassay for evaluating the toxicity of toxic chemicals was applied and 96h-EC50 of phenol, o-chlorophenol, 2,4-dichlorphenol and pentachlor-phenol on inhibition of S. Obliqnus' growth were calculated as 341, 85, 25 and 1.5 ml·l-1, respectively. It was found that phenol could not be biodegradated by S. Obliqnus on the initial concentration 300, 350 and 400ml·l-1, respectively, and even in almost there was no inorganic carbon in media.
