生物测试法应用于判别除草剂环境污染

Application of Bioassay to Distinguishing Herbicide Pollution

在实验室条件下进行了阿特拉津、乙草胺、甲磺隆3种除草剂对玉米根长抑制试验。结果表明,受试玉米对3种除草剂的敏感顺序为甲磺隆>乙草胺>阿特拉津。将此结果应用于农药环境污染事故的调查与诊断工作中,对污染因子进行了初步的分析和判定。

Bioassay of three types of herbicides-Atrazine, Acetochlor and Metsulfuron-methyl has been conducted under laboratory conditions, with the indicator of growth inhibition of maize roots. The results showed that the sensitivity order of maize to the tested herbicides were: Metsulfuron-methyl > Acetochlor > Atrazine. The conclusion was applied to a case study of investigation and distinguishing of pesticide pollution accident to provide primary evidence for analyzing and determining the pollution substances.
