Residual pesticides in mushroom have emerged as a significant concern and bring much uncertainty due to processing procedures. In this study, a modified QuEChERS sample preparation procedure and UPLC-MS/MS were used to analyze the residual levels of four commonly used pesticides in from field to product processing. The field results showed that dissipation of these targeted chemicals was consistent with the first-order kinetics, and the half-life time ranged from 20.4 h to 47.6 h. The terminal residues of the four pesticides at harvest time ranged from 9.81 to 4412.56 μg/kg in raw mushroom. The processing factors (PFs) of clothianidin, diflubenzuron, chlorbenzuron, and pyridaben ranged from 0.119 to 0.808 for the drying process and from 0.191 to 1 for the washing process. By integrating the data from the field trials, the PFs, and the consumption survey, the chronic dietary risks of the target chemicals via intake ranged from 2.41 × 10 to 5.69 × 10 for children and from 6.34 × 10 to 1.88 × 10 for adults, which are considerably below the threshold of 1, indicating no unacceptable risk to consumers in the Fujian province of China. This research offers foundational data for appropriate use and the maximum residue limit (MRL) establishment for these four insecticides in .
蘑菇中的残留农药已成为一个重大问题，并且由于加工过程而带来了诸多不确定性。在本研究中，采用改进的QuEChERS样品制备方法和超高效液相色谱-串联质谱法，分析了从田间到产品加工过程中四种常用农药的残留水平。田间结果表明，这些目标化学物质的消散符合一级动力学，半衰期在20.4小时至47.6小时之间。四种农药在收获时的最终残留量在鲜蘑菇中为9.81至4412.56μg/kg。噻虫胺、敌草隆、灭幼脲和哒螨灵在干燥过程中的加工因子（PFs）为0.119至0.808，在清洗过程中为0.191至1。通过整合田间试验数据、加工因子和消费调查，目标化学物质通过蘑菇摄入对儿童的慢性膳食风险为2.41×$10^{-5}$至5.69×$10^{-5}$，对成人的风险为6.34×$10^{-6}$至1.88×$10^{-5}$，均远低于1的阈值，表明对中国福建省的消费者不存在不可接受的风险。本研究为这四种杀虫剂在蘑菇中的合理使用和最大残留限量（MRL）制定提供了基础数据。
