摘要:

土壤微塑料通常伴随着重金属同时存在,二者相互作用可能改变彼此的迁移转化行为和生物有效性,从而导致植物对镉的吸收积累发生变化,给农产品安全带来新的挑战。文章综述了土壤微塑料的污染现状及其与镉的相互作用,对微塑料影响植物吸收积累镉的因素和途径进行了分析,微塑料可通过影响土壤理化性质及微生物群落结构改变镉的生物有效性,并与镉形成复合物进入植物根系增加植物吸收积累镉的风险。同时,微塑料对植物的生长发育和代谢均产生一定影响,并能够诱导植物产生氧化应激反应,从而影响植物对镉的吸收积累。最后,本文对未来微塑料在土壤-植物系统中的研究进行了展望,为复合污染风险的评估与治理以及粮食安全生产提供科学依据。

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
