我国农药最大残留限量标准过严的实证分析

在农产品质量信息不对称、市场监管不到位的情况下,农药最大残留限量标准制定过严,不但不能保护消费者健康和农业生态环境,反而会加剧农产品的农药残留问题泛滥。利用农药最大残留限量(MRLs)、日允许摄入量(ADI)与被测食品每日最大理论摄入量(TDI)三者之间的数量关系,以《食品中农药最大残留限量》GB2763-2005为例,计算了126种农药439个残留指标的TDI值,发现有111个残留指标的TDI值远远大于我国居民每日实际摄入量(RDI),占GB2763-2005国家标准478个残留限量指标的23.22%,表明我国农药最大残留限量国家标准部分指标值设定存在过严的倾向,建议政府尽快修订该标准,以消除食品安全管理隐患。

A positive analysis of excessively rigorous proof of the standards about maximum residue limits for pesticide in agri-food

Under the information asymmetry and market supervision lack of agri-food quality,the excessively rigorous standard of maximum residue limits(MRLs)for pesticide in agrifood is not only unbeneficial to protect consumer health and ecological environment,but also aggregate serious pesticide residues in agrifood.Taking national standard Maximum Residue Limits for Pesticides in Food(GB2763-2005)as a case,calculated the Theory Daily Intake(TDI)related agrifoods of 439 residue indexes of 126 pesticides with the quantity relation between MRLs,acceptable daily intake(ADI)and TDI,and compared with the customer’s Real Daily Intake(RDI)related agrifoods.It was found that there were 111 residue indexes related agri-foods which TDI were overly above and beyond their RDI of Chinese residents,accounted for 23.22% of 478 pesticide residue indexes in this national standards.This evidence proved that the national standard had the excessively rigorous tendency really and suggested our government would revise this standard at once in order to eliminate the food safety management trap.
