Abstract:

As an emerging contaminant, microplastics pose severe threats to global ecological security due to their persistence, mobility, and ecotoxicity. In arid regions of China, particularly within sandy and windy zones, the combination of dry climate, high surface exposure rate, and frequent aeolian activities makes these areas critical sources and important transmission pathways for the migration and diffusion of microplastics at the soil-atmosphere interface. To reveal the environmental risks associated with the wind-driven migration of microplastics in arid regions, this paper systematically analyzes the occurrence characteristics and spatial variations of soil microplastics in the arid northwest China through literature review. It further explores the migration and diffusion processes of microplastics into the atmosphere driven by wind erosion, along with their influencing factors. Additionally, the environmental risks posed by airborne microplastics are assessed. This review holds significant scientific and practical importance for deepening the understanding of terrestrial microplastic environmental behavior, safeguarding China's ecological security, and improving the environmental risk assessment framework for microplastics.
