| Abstract: |
To evaluate the toxic effects of environmental contaminant PFOS on green algae, Scenedesmus obliqnus was cultured in media containing serially diluted PFOS for evaluation of proliferation capacity and some physiological indexes. Within 96h, PFOS doses ≥50 mg/L all inhibited the proliferation speed of Scenedesmus obliqnus(p<0.05). The 96h EC50 value of PFOS was determined to be 126 mg/L. In a chronic experiment with 8 days of PFOS treatment, chlorophyll a content, which was inhibited by even the lowest dose, showed to be the most sensitive index to PFOS contamination. PFOS doses ≥100mg/L all resulted in decreasing of antioxidant enzyme activity and increasing of MDA content in Scenedesmus obliqnus(P<0.05). |
