内蒙古地区蔬菜中农药残留风险评估

Current status of pesticide residues in vegetables and fruits and progress in risk assessment

摘要:

目的：了解内蒙古地区蔬菜中农药的残留情况，对内蒙古地区蔬菜中农药残留风险进行评估。方法：利用2016-2019年内蒙古地区风险监测的蔬菜中农药残留数据，选用风险系数法对我区居民通过蔬菜摄入的农药残留进行风险评估。结果：经计算所得内蒙古地区蔬菜中不同种农药的风险系数R均小于1.5。结论：内蒙古地区居民蔬菜中农药残留风险总体处于低水平，单一农药残留风险水平处于低度风险。

Abstract:

Objective To review the status of pesticide residues in vegetables and fruits and the progress of risk assessment, and to provide data support for pesticide residue research, residents' dietary exposure risks and safety risk management. Methods Domestic and international literature and research data available are reviewed and analyzed. Results This article mainly reviews the literature on the investigation of current status of pesticide residues in vegetables and fruits. It also discusses several methods and models that have been widely employed in the dietary exposure risk assessment of pesticide residues worldwide. Conclusion Pesticide residues have been frequently reported in vegetables and fruits, mainly including organophosphorus, organochlorine, carbamate and pyrethroid pesticide residues. The relevant risk assessment results indicate that different groups of people, especially those with high exposure, have cumulative dietary exposure risks to pesticides in vegetables and fruits. Although most pesticide residues have been detected at low concentrations in vegetables and fruits, they have potential toxicity risks and require continuous attention.
