  • 摘要:
    目的 明确新疆大豆农药残留情况，评估其膳食摄入风险，为更好的研究大豆膳食摄入风险评估、了解新疆大豆农药残留的潜在风险，为新疆大豆质量安全管理提供科学依据。
    方法 本研究以新疆大豆生产区 82 份样品为研究对象，采用液相色谱 - 质谱法和气相色谱 - 质谱法分别对 89 种农药残留进行测定，通过慢性膳食摄入风险（%ADI）、急性膳食摄入风险（%ARfD）和风险排序矩阵法（FSA）进行风险评估与排序。
    结果  82 份大豆样品中共检出 28 种农药残留，未检出农药超标样品，安全性评估中%ADI和%ARfD值均小于1。检出农药中包括 5 种中等风险农药，其余均为低风险农药。经风险指数分析，发现大豆样品以低风险、极低风险为主，占全部样品的97.56%。
    结论 新疆大豆样品农药残留风险总体良好，膳食摄入风险可接受。

     

    Abstract:
    Objective To clarify the situation of soybean pesticide residues in Xinjiang and assess their dietary intake risks, so as to lay a scientific basis for better study of soybean dietary intake risk assessment and understanding of potential risks of soybean pesticide residues in Xinjiang in the hope of providing a scientific basis for the quality and safety management in this region.
    Methods In this study, 82 samples of soybean production areas in Xinjiang were used as research objects, and 89 pesticide residues were determined by liquid chromatoc-mass spectrometry and gas chromatoc-mass spectrometry. Risk assessment and ranking were conducted by chronic dietary intake risk (%ADI), acute dietary intake risk (%ARfD) and risk ranking matrix (FSA).
    Results A total of 28 pesticide residues were detected in 82 soybean samples, and no pesticide exceeded the standard. In the safety evaluation, %ADI and %ARfD values were less than 1. The detected pesticides included 5 kinds of medium risk pesticides, and the rest were low risk pesticides. By risk index analysis, it was found that the soybean samples were mainly of low risk or very low risk, accounting for 97.56% of all samples.
    Conclusion The overall risk of pesticide residues in Xinjiang soybean samples is good, and the dietary intake risk is acceptable.
