Abstract: The growth effects of bensulfuron methyl of different concentrations on Chlorella pyrenoidosa were studied through 96h acute toxicity tests in this paper. The results showed that bensulfuron methyl accelerated the growth of algae at lower concentration （<1mg/L） with content increase of chlorophyll or protein, and inhibited the growth of algae at higher concentration (>5mg/L). The content of chlorophyll or protein in algae cells reduced with the increasing concentration of bensulfuron methyl, exhabiting the good concentration-effect relationship. The 96h-EC50 of bensulfuron methyl upon the algae was 15.7mg/L.

Key words: bensulfuron methyl, chlorella pyrenoidosa, growth, chlorophyll, protein
