Pesticides play an important role in increasing the overall yield and productivity of agricultural foods by controlling pests, insects, and numerous plant-related diseases. However, the overuse of pesticides has resulted in pesticide contamination of food products and water bodies, as well as disruption of ecological and environmental systems. Global health authorities have set limits for pesticide residues in individual food products to ensure the availability of safe foods in the supply system and to assist farmers in developing the best agronomic practices for crop production. Therefore, the use of nondestructive testing (NDT) methods for pesticide residue detection is gaining interest in the food supply chain. The NDT techniques have several advantages, such as simultaneous measurement of chemical and physical characteristics of food without destroying the product. Although numerous studies have been conducted on NDT for pesticide residue in agro-food products, there are still challenges in real-time implementation. Further study on NDT methods is needed to establish their potential for supplementing existing methods, identifying mixed pesticides, and performing volumetric quantification (not surface accumulation alone).
农药通过控制害虫、昆虫和多种与植物相关的病害，在提高农产品的总产量和生产率方面发挥着重要作用。然而，农药的过度使用导致了食品和水体的农药污染，以及生态和环境系统的破坏。全球卫生当局已对各类食品中的农药残留设定了限量，以确保供应系统中安全食品的可获得性，并帮助农民制定最佳的作物生产农艺实践。因此，在食品供应链中，使用无损检测（NDT）方法进行农药残留检测正受到越来越多的关注。无损检测技术具有多个优点，例如能够在不破坏产品的情况下同时测量食品的化学和物理特性。尽管已经针对农产品中的农药残留无损检测开展了大量研究，但在实时应用方面仍然存在挑战。需要对无损检测方法进行进一步研究，以确定其在补充现有方法、识别混合农药以及进行体积定量（而非仅表面累积量）方面的潜力。
