Abstract:
Objective Microplastics (MPs) contamination is a potential threat to agroecosystems. They affect crop growth directly or indirectly by changing soil environmental conditions on the one hand, and may endanger human health through food chain transmission on the other. Microplastics in freshwater and marine ecosystems have been studied frequently, and research on the soil media with higher microplastic contents have also been paid attention, especially the exploration of the extent and mechanisms of microplastic contamination in agricultural soil ecosystems is urgently needed.
Methods This paper analyzes the detection methods and environmental behavior of soil microplastics by using CNKI and Web of Science core database as the main sources.
Results The source distribution, detection methods, transport and influence mechanisms of microplastics in agricultural soils are summarized, and the outlook and suggestions for the current research are presented.
Conclusion It is important to establish a more standardized and unified monitoring standard for soil microplastics, to systematically grasp the source, abundance and pollution mechanism of microplastics in farmland, and to take targeted prevention and control measures to reduce their negative impact on agricultural production and human health.
