土壤中微塑料的来源、赋存特征及迁移行为

The Source,Occurrence Characteristics and Migration Behavior of Microplastics in Soil

微塑料作为一种新兴的持久性有机污染物,具有颗粒粒径小、在环境中难降解、吸附有毒污染物等特点,备受国内外研究者关注。近年来,土壤中微塑料的污染形势愈发严峻,该文综述了土壤环境中微塑料的来源、赋存特征、检测方法和迁移行为。分析总结了土壤中微塑料负载污染物的迁移机制以及影响迁移的因素,最后针对治理土壤中微塑料污染和控制其迁移行为问题提出了一些展望,为未来的微塑料污染土壤修复提供一些思路。

As emerging persistent organic pollutants,microplastics have the characteristics of small particle size,difficult degradation in the environment and easy to adsorb toxic pollutants,which led to increasing global concern.In recent years,the pollution of microplastics in soil has become increasingly serious.The source,occurrence characteristics,detection methods and transfer behavior of microplastics in soil environment were reviewed in this paper,and the transfer mechanism and influencing factors of microplastics-loaded pollutants in soil were analyzed and summarized.Finally,some prospects are put forward for the controlling of both pollution and transfer behavior of microplastics in soil.The conclusions of this paper could provide some ideas for the remediation of microplastics pollution in soil.
