摘　　要：【目的】制备均匀性及稳定性满足要求的水果类基质农药残留能力验证样品,并应用于食品农药残留检测能力的验证考核。【方法】选择无污染的苹果为主要原料,制备腈菌唑、腐霉利农药残留能力验证样品,并进行均匀性和稳定性的评价。采用迭代稳健统计和Z值统计分析参加能力验证的实验室检测结果。【结果】制备能力验证样品的均匀性以及稳定性良好,符合能力验证样品要求。根据评价原则,在全国109家参加能力验证的实验室中,有107家(98.2%)实验室的结果满意,2个考核项目各有1家实验室检测结果可疑。【结论】研制的苹果粉基质农药残留能力验证样品满足本次能力验证的要求,为食品农药残留检测实验室提供有效的外部质量控制工具。[Objective]To prepare pesticide residues in fruit matrix samples that meet the requirements of homogeneity and stability for the proficiency test.[Methods]The pollution-free apple was selected as the main raw material to prepare the pesticide residue proficiency test samples of myclobutanil and procymidone,and to evaluate the homogeneity and stability. The results of the proficiency test were assessed using robust analysis and Ζ value.[Results]The homogeneity and stability of the reference materials met the relevant requirements. Among 109laboratories participated in the proficiency testing,107(98.2%)laboratories had satisfactory results. Suspicious test results were reported only in two laboratories,one laboratory for each of the two assessment items.[Conclusion]An apple powder matrix sample with pesticide residues is successfully prepared for proficiency test,and could provide an evaluation tool for pesticide residue testing laboratories.
