摘要:【目的】研究苄嘧磺隆对蛋白核小球藻(Chlorella pyrenoidosa)的生长效应,评价苄嘧磺隆的生态
风险。【方法】通过不同浓度的苄嘧磺隆对蛋白核小球藻的 96 h 急性毒性试验,研究苄嘧磺隆对小球藻的生长及
藻细胞中叶绿素和蛋白质含量的影响。【结果】低浓度苄嘧磺隆(<1 mg·L-1)具有刺激藻细胞生长的作用,其叶
绿素含量和蛋白质含量均有明显的增加;高浓度的苄嘧磺隆(>5 mg·L-1)抑制藻的生长,藻细胞叶绿素含量和可溶
性蛋白质含量随药剂浓度增加而明显下降,且表现出较好的计量-效应关系,其对蛋白核小球藻的 96h-EC50 值为
mg·L-1。【结论】苄嘧磺隆对蛋白核小球藻的生长有一定的抑制作用,属低毒。

Abstract:【Objective】To study the growth effects of differing concentrations of Bensulfuron-Methyl on Chlorella pyrenoidosa
and to evaluate the ecological risk. 【Method】The effects of Bensulfuron-Methyl on the growth and the content change of
chlorophyll and protein in Chlorella pyrenoidosa were studied through 96 h acute toxicity tests. 【Result】Bensulfuron-Methyl
accelerated the growth of algae at a lower concentration (<1 mg·L-1) with content increase of chlorophyll or protein, and it inhibited
the growth of algae at higher concentration (>5 mg·L-1). The content of chlorophyll or protein in algae cells reduced with the
increasing concentration of Bensulfuron-Methyl, exhibiting t
