| Abstract: | Dunaliella salina,a unicellular green alga of environmental tolerance,was employed as test organism to investigate the toxicity effects of a pesticide trichlorfon.The influences of trichlorfon on cell growth,β-carotene level and activities of superoxide dismutase(SOD) and catalase(CAT) were investigated.At the concentrations less than 0.050 g/L trichlorfon,cell responses were similar to that of the control.When treated with 0.075~0.100 g/L trichlorfon,cell growth and β-carotene levels declined at first and then revived.When concentrations were higher than 0.125 g/L trichlorfon,both cell growth and β-carotene levels decreased until they were undetectable.The 10-d IC50 of trichlorfon on D.salina was 0.179 g/L.Trichlorfon could stimulate the increase of CAT activity at a low concentration. |
