摘　　要：采用3种快速检测试剂盒对敌敌畏、敌百虫、辛硫磷、三唑磷等4种有机磷农药进行4个浓度水平的比对检测试验,考察各试剂盒检测的灵敏度。结果表明,不同来源的试剂盒对蔬菜样品中同一种农药残留进行检测时灵敏度不同,且当蔬菜样品中农药残留量越高时测试误差越小。建议基层检验检测机构在使用农药残留快速检测方法时做好快检试剂盒的采购及验收工作,并用气相色谱等仪器方法对快速检测方法检出的阳性样品进行确证。Three rapid detection kits were used to compare the sensitivity of four organophosphate pesticides,including dichlorvos,dichlorvos,phoxim,and triazophos,at four concentration levels.The results indicate that different sources of reagent kits have different sensitivities when detecting the same pesticide residue in vegetable samples,and the higher the amount of pesticide residue in vegetable samples,the smaller the testing error.It is recommended that grassroots inspection and testing institutions purchase and accept rapid detection kits when using pesticide residue rapid detection methods,and confirm positive samples detected by rapid detection methods using instruments such as gas chromatography.
