摘要
为给农药的合理使用和最大残留限量标准的制定提供依据,随机采集多份菠菜样品,对其中的68种农药残留进行检测并得出详细实检测数据。在此基础上,运用慢性、急性膳食摄入风险评估模型,对农药残留的风险进行了全面分析;运用风险矩阵对LD50值、ADI值、该农药残留的食品占总膳食的比例、农药使用频率、是否存在高暴露人群、检测中值分别赋分的方式进行风险排序。结果显示,急性和慢性膳食摄入风险均在可接受范围内。建议对菠菜种植中对农药使用加强监控和指导,加快农药对高危人员多残留的研究,作好菠菜中农药合理使用的指导。
In order to provide a basis for the rational use of pesticides and the formulation of the maximum residue limit standard,a number of Spinacia oleracea samples were randomly collected to detect 68 kinds of pesticide residues and obtain detailed detection data.On this basis,the risk assessment model of chronic and acute dietary intake was used to analyze the risk of pesticide residues.The risk matrix was used to rank the LD50 value,ADI value,the proportion of the pesticide residues in the total diet,the frequency of pesticide use,whether there is a high exposure population,and the detection median value.The results showed that both acute and chronic dietary intake risks were within acceptable limits.It is suggested to strengthen the monitoring and guidance of pesticide use in Spinacia oleracea cultivation,speed up the research of pesticide residue on high-risk personnel,and make guidance on the rational use of pesticides in Spinacia oleracea.
