三七为多年生中药材,具有严重的生产障碍问题,生长过程中易发多种病虫害,当前主要的防治方法为化学农药防控,因而三七农药残留问题备受关注。该文综述了1981—2021年40年间三七中常见农药残留种类、检测方法,并比较了国内外有关三七农药残留的限量标准,以期为指导三七合理用药、控制药材质量提供参考,从而推动中国三七产业的持续发展。当前三七药材农药残留研究仅40篇公开发表文献,存在严重的研究不足问题。目前利用色谱-串联质谱技术可同时检测出三七中上百种农药残留,农药检出从早期的双对氯苯基三氯乙烷(滴滴涕)、六氯环己烷(六六六)、对硫磷等禁用农药逐步转变为烯酰吗啉、腐霉利、丙环唑、苯醚甲环唑等低毒农药,来自三七中农药残留的膳食风险较低,不会对食用者造成健康危害。该研究认为积极开展三七农药残留质量标准的研制工作,在保留标准中已有农药的基础上,增加生产实际中应用的农药,指导农户科学使用农药,将是未来工作的重点方向。
