农业杀虫剂敌百虫对杜氏盐藻的毒性作用
Toxic Effects of Chemical Pesticide Trichlorfon on Dunaliella salina
摘要
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 0.0S0 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 (hey 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.关键词
