Agricultural pollutants are harmful components threatening human health, wildlife, the environment, and the ecosystem. To avoid their exposure, developing prevention and detection systems with high sensitivity and selectivity is required. Most conventional methods, including molecular and chromatographic techniques, cannot be adopted for outdoor on-site detection even though they can provide sensitive and selective detection. Thus, detection platforms that can provide on-site detection via miniaturized and high throughput systems should be developed. As an alternative method, surface-enhanced Raman scattering (SERS) provides unique information about the substances in the presence of plasmonic nanostructures, and it can be portable with the use of portable detection systems and spectrometers. In this study, on-site detection of agricultural pollutants through SERS is reviewed. Three different types of agricultural pollutants were pointed out. On-site detection of biological pollutants, including bacteria and viruses, is reviewed as the first type of pollutant. As a second type, the detection of pesticides, antibiotics, and additives are focused on as chemical pollutants. The third group includes the detection of microplastics and also nanoparticles from the environment.
农业污染物是威胁人类健康、野生动物、环境和生态系统的有害成分。为避免接触这些污染物，需要开发具有高灵敏度和选择性的预防与检测系统。大多数传统方法，包括分子和色谱技术，尽管能够提供灵敏且具选择性的检测，但无法用于户外现场检测。因此，应开发能够通过小型化和高通量系统进行现场检测的平台。作为一种替代方法，表面增强拉曼散射（SERS）在等离子体纳米结构存在的情况下可提供有关物质的独特信息，并且借助便携式检测系统和光谱仪可实现便携化。在本研究中，对通过SERS进行农业污染物的现场检测进行了综述。指出了三种不同类型的农业污染物。作为第一种污染物类型，对包括细菌和病毒在内的生物污染物的现场检测进行了综述。作为第二种类型，重点关注农药、抗生素和添加剂等化学污染物的检测。第三类包括环境中微塑料以及纳米颗粒的检测。
