摘要/Abstract

摘要： 为评价农药在稻田使用后对水生生物的安全性,选择啶虫脒、丙溴磷、二嗪磷和马拉硫磷4种杀虫剂为供试药剂,分别采用静态法和半静态法研究其对斜生栅列藻(Scenedesmus obliquus)、大型溞(Daphnia magna Straus)和斑马鱼(Brachydanio rerio)3种水生生物的急性毒性,并进行环境安全性评价。结果表明：啶虫脒、丙溴磷、二嗪磷和马拉硫磷对斜生栅列藻的72h-EC50值分别为55.3,0.00509,0.249,1.69 mg·L-1,其毒性级别分别为低毒、高毒、高毒和中毒。啶虫脒、丙溴磷、二嗪磷和马拉硫磷对大型溞的48h-EC50值分别为49.2,0.00392,0.03080,0.00165 mg·L-1,其毒性级别分别为低毒、剧毒、剧毒和剧毒。啶虫脒、丙溴磷、二嗪磷和马拉硫磷对斑马鱼的96h-LC50值分别为49.8,0.706,5.12,10.9 mg·L-1,其毒性级别分别为低毒、高毒、中毒和低毒。

Abstract: In order to assess the safety of pesticides used in paddy field to aquatic organisms, the acute toxicity of acetamiprid, profenofos, diazinon and malathion were studied using Scenedesmus obliquus, Daphnia magna Straus and Brachydanio rerio as test organisms by static test, static test and semi\|static test respectively. Safety evaluation had also been conducted. The results showed that acetamiprid, profenofos, diazinon and malathion had low toxicity (55.3 mg·L-1, 72h-EC50), high toxicity (0.00509 mg·L-1, 72h-EC50), high toxicity (0.249 mg·L-1, 72h-EC50), and moderate toxicity (1.69 mg·L, 72 h-EC50) to Scenedesmus obliquus, respectively. It could be seen that acetamiprid, profenofos, diazinon and malathion had low toxicity (49.2 mg·L-1, 48h-EC50), extremely high toxicity (0.00392 mg·L-1, 48h-EC50), extremely high toxicity (0.0308 mg·L-1, 48h-EC50), and extremely high toxicity (0.00165 mg·L-1, 48h-EC50) to Daphnia magna Straus, respectively. As for Brachydanio rerio, acetamiprid, profenofos, diazinon and malathion had low toxicity (49.8 mg·L-1, 96h-LC50), high toxicity (0.706 mg·L-1, 96h-LC50), modreate toxicity (5.12 mg·L-1, 96h-LC50) and low toxicity (10.9 mg a.i.·L-1, 96 h-LC50) , respectively．
