[目的]对吉林省粮食中有机氯农药残留量进行调查与分析。[方法]采用气相色谱仪-电子捕获检测器法(GC-ECD),对吉林省地产大米、玉米、大豆、红豆、绿豆5种农产品中的六六六、滴滴涕、六氯苯、五氯硝基苯4种有机氯农药残留量进行检测。[结果]被测农产品中,大豆、红豆、绿豆3种豆类产品中,邻,对′-滴滴涕的残留量超标率分别为6.25%、12.5%、12.5%,其余检测结果均未超过国家标准。[结论]吉林省地产粮食中有机氯农药的污染已基本降到安全水平。
[Objective] The research aimed to investigate and analyze the organochlorine pesticide residues in grain in Jilin Province. [Method] The content of BHC, DDT, HCB, PCN in five kinds of agricultural products of Jilin Province, such as real estate rice, corn, soybean, red bean and mung bean, were determined by gas chromatography- electron capture detector Four kinds of organochlorine pesticide residues of benzene were detected. [Result] The over-standard rates of residues of o-DDT and DDT in soybean, red bean and mung bean under test were 6.25%, 12.5% and 12.5%, respectively.
