中国食品中农药残留膳食暴露评估关键要素及情景分析

    Scenario analysis of the principal elements of dietary exposure assessment of pesticide residues in food in China

    • 摘要: 本文主要围绕构成中国食品中农药残留膳食暴露评估框架的毒理学数据、残留化学数据和膳食消费数据3个关键要素,对与限量标准制定和农产品质量安全研判相关的膳食暴露评估主观目标和客观要求、对评估模型的理解和在限量标准制定及实施过程中的应用、数据的不确定性与变异性、以及适度保护水平的把控等内容进行了解析,从不同情景层次对提高膳食暴露风险评估科学性和限量标准的质量进行了讨论。针对目前存在的问题,提出了改进中国农药残留膳食暴露评估方法体系的参考建议。

       

      Abstract: Focused on the three principal elements, toxicological data, residual chemistry data, and dietary consumption data during the construction of Chinese framework of dietary exposure assessment of pesticide residues in food, the following issues, namely the subjective goal and objective requirement of the exposure assessment for residue limits elaboration and pesticide residue related safety judgment of agro-products, understanding of the assessment models and their application during the process of residue limit elaboration and implementation, estimation of result uncertainty, variability and setting the appropriate level of protection, and enhancing the scientific nature of the dietary exposure assessment and raising the quality of the standards of residue limits in various scenario of the assessment process were analyzed. Aimed at overcoming the weakness of the current practice, measurements to refine the Chinese dietary risk assessment of pesticide residues in food were suggested.
