关于JMPR植物源产品残留定义中含有代谢产物的农药在进行膳食风险评估时残留数据计算的介绍

联合国粮农组织和世界卫生组织农药残留联席会议(JMPR)将农药残留定义分为2类,即植物源产品残留定义和动物源产品残留定义;同时根据使用目的不同,又将农药残留定义分为风险评估残留定义和监测残留定义。JMPR在植物源产品农药风险评估残留定义中包含的代谢产物类型主要分4种情况:一是残留定义包含母体和代谢产物,代谢产物是农药;二是残留定义包含母体和代谢产物,代谢产物不是农药;三是残留物定义只包括代谢产物,且代谢产物不是农药;四是二硫代氨基甲酸酯类农药。本文综述了JMPR关于植物源产品残留定义中含有代谢产物的农药进行农药残留膳食风险评估时残留数据的计算,旨在为我国制定农药最大残留限量标准进行农药残留膳食风险评估时提供借鉴和参考。

Conversion of residue data for pesticide residue definition containing metabolites in dietary risk assessment for plant commodities of JMPR

Pesticide residue definition are categorized into two groups according to the Joint FAO/WHO Meeting on Pesticide Residues(JMPR),namely,residue definition for plant and animal commodities,and pesticide residue definition with its different purposes of usage are classified for estimation of dietary intake and for compliance with maximum residue limit(MRL).Residue definition for estimation of dietary intake in the plant origin are mainly divided into four categories.Firstly,the residue definition includes parent compound and metabolites,and the metabolites are pesticides.Secondly,the residue definition includes parent compound and metabolites,and the metabolites are not pesticides.Thirdly,the residue definition only includes metabolites,and the metabolites are not pesticides.Fourthly,the residue definition includes dithiocarbamate(DTCs).This paper reviews the JMPR’s conversion of residual data for pesticides containing metabolites in residue definition for estimation of dietary intake in plant commodities,which aims to provide references for pesticide residue dietary risk assessment when setting MRL in China.
