摘要:

为探明4种未登记农药(腐霉利、氯虫苯甲酰胺、甲维盐和多效唑)在黄桃上的安全性和消解特性,在施药后套袋和施药后不套袋2种处理方法下,开展了这4种农药在黄桃中的消解动态与膳食风险评估研究。建立了液相色谱-串联质谱联用(LC-MS/MS)分析方法同时测定黄桃中4种未登记农药残留量。结果表明,在0.05~5.0 mg·kg-1(腐霉利、氯虫苯甲酰胺和多效唑)和0.001~0.05 mg·kg-1(甲维盐)添加水平下,4种农药的平均回收率为75.6%~111.3%,相对标准偏差(RSD)为0.9%~5.2%。4种农药在黄桃中的降解均符合一级动力学方程。根据农药残留和风险评估结果,在推荐剂量下甲维盐和多效唑建议在黄桃上设置14 d的安全间隔期(PHI),氯虫苯甲酰胺建议设置3 d的PHI;腐霉利因降解比较缓慢,不建议在黄桃生产上使用。

Abstract:

To clarify food safety and dissipation dynamics of four unregistered pesticides (procymidone, chlorantraniliprole, emamectin benzoate and paclobutrazol) in yellow peach, the degradation dynamics and dietary risk assessment of these four pesticides in yellow peach were studied under two treatment methods of bagged and non-bagged. Based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology, a simple and practical method was established to measure the residues of four unregistered pesticides in yellow peach. The mean recoveries of four pesticides in yellow peach were 75.6%-111.3% at spiking levels from 0.05 to 5.0 mg·kg-1 (procymidone, chlorantraniliprole and paclobutrazol) and 0.001 to 0.05 mg·kg-1 (emamectin benzoate) with relative standard deviation (RSD) of 0.9%-5.2%. The degradation of four pesticides in the yellow peach accorded with the first-order kinetic equation. Based on the results of pesticide residue and risk assessment, emamectin benzoate and paclobutrazol should be used on the yellow peach with a preharvest interval (PHI) of 14 days, and chlorantraniliprole should be used on the yellow peach with a PHI of 3 days at the recommended dose. Due to the slow degradation of procymidone, it is not recommended to use procymidone in yellow peach.
