doi:10.16178/j.issn.0528-9017.20250189

Abstract

Abstract:

Soil microplastics often coexist with heavy metals, and their interaction may alter the migration, transformation behaviors, and bioavailability of each other, leading to changes in the absorption and accumulation of cadmium by plants, thereby posing new challenges to agricultural product safety. This article reviews the current status of soil microplastic pollution and its interaction with cadmium, analyzing the factors and pathways through which microplastics influence the absorption and accumulation of cadmium by plants. Microplastics can affect the bioavailability of cadmium by altering soil physicochemical properties and microbial community structures, and can form complexes with cadmium that enter plant roots, increasing the risk of cadmium absorption and accumulation by plants. Additionally, microplastics have certain impacts on plant growth, development, and metabolism, and can induce oxidative stress responses in plants, thereby affecting the absorption and accumulation of cadmium. Finally, this article provides an outlook on future research regarding microplastics in the soil-plant system, offering a scienjpgic basis for the assessment and management of composite pollution risks and the safety of food production.

Key words: soil-plant system, microplastics, cadmium, accumulation
