摘　　要：本实验采用气相色谱法(GC-ECD)进行农药残留检测,研究了百菌清、溴氰菊酯在豇豆上的残留降解动态和最终残留量。结果表明,按照农药推荐使用量,百菌清、溴氰菊酯的半衰期分别为1.82 d、1.07 d,在豇豆中不具有积累性残留效果。参照我国、日本和国际食品法典委员会(CAC)规定的残留限量要求,计算出两种农药的安全间隔期,建议百菌清、溴氰菊酯的安全间隔期分别为5 d和3 d,应该执行良好农业操作,严格遵照农药标签说明使用。In this experiment,gas chromatography was used to detect pesticide residues,and the residual degradation dynamics and final residues of chlorothalonil and deltamethrin on cowpea were studied.The results show that the two pesticides have different half-lives and have no cumulative residue effect in cowpea.According to the recommended pesticide dosage,the half-lives of chlorothalonil and deltamethrin are 1.82 d and 1.07 d,respectively.With reference to the residue limit requirements set by China,Japan and the Codex Alimentarius Commission,the safe interval of the two pesticides is calculated.It is recommended that the safe interval of chlorothalonil and deltamethrin be 5 d and 3 d,respectively.Good agriculture should be implemented.Operation,strictly follow the pesticide label instructions.
