本文通过粮食中有机磷农药残留回收率的实验,探讨农药残留检测的实验条件。按照GB/T5009.20-2003《食品中有机磷农药残留量的测定》第2法进行前处理和检测,结果显示回收率情况比较理想。验证了在适合的条件下有机磷农药检测能够得到比较满意的结果。有机磷农药在农业生产中使用广泛,造成严重的粮食污染。国家比较重视农药残留的监控,农药检测方面的标准更新也较快。
In this paper, experiments on the recovery of organophosphorus pesticide residues in grain were conducted to investigate the experimental conditions of pesticide residue detection. According to GB / T5009.20-2003 “determination of organophosphorus pesticide residues in food” method 2 pre-treatment and testing, the results show that the recovery rate is ideal. It was verified that organophosphorus pesticides could get satisfactory results under the suitable conditions. Organophosphorus pesticides are widely used in agricultural production, causing serious food contamination. Countries pay more attention to the monitoring of pesticide residues, pesticide testing standards update faster.
