摘　　要：研究了一种毒性很高的氨基甲酸酯类杀虫剂———涕灭威和广泛使用的阴离子表面活性剂十二烷基苯磺酸钠 (SDBS)组成的复合污染体系对斑马鱼胚胎DNA的影响 .结果表明 ,涕灭威对斑马鱼胚胎DNA的损伤随浓度增大而加重 ,但低浓度涕灭威在短时间内造成的DNA单链断裂是可以修复的 ,高浓度则导致难以修复的双链断裂 .一定浓度 ( 2 0mg·L-1)This paper deals with the impact of a complex pollution system composed of a very toxic carbamate pesticide,aldicarb and the widely used anionic surfactant,sodium dodecylbenzenesulfonate(SDBS),on DNA of zebrafish( Brachydanio rerio ) embryo. The results indicated that DNA damage caused by aldicarb became more serious with its increasing concentration,but single strand break caused by aldicarb in low concentration and short time could be repaired,and high concentration led to double strand break which was difficult to repaire. SDBS in certain concentration (20 mg·L -1 ) could reduce the toxicity of aldicarb in the complex pollution system.
