摘要
土壤中微塑料与重金属污染是当前环境科学领域备受关注的热点问题。微塑料作为新型环境污染物,因其载体特性对土壤重金属的迁移转化行为产生一定影响,然而当前尚缺少系统论述。阐明微塑料如何影响重金属在土壤环境中的迁移转化过程,对保障农产品安全和制定土壤污染防控策略具有十分重要的意义。基于此,系统综述了微塑料对重金属在土壤中分布、迁移及生物有效性的影响,阐述了微塑料影响土壤重金属迁移转化行为的内在机制,以期为保障土壤生态环境安全和促进农业绿色发展提供科学依据。
The contamination of soil by microplastics and heavy metals is a widely debated issue in current environmental science.As a new type of environmental pollutant,microplastics have a certain impact on the migration and transformation of heavy metals in soil due to their carrier properties.However,there is currently a lack of systematic research.Clarifying how microplastics affect the migration and transformation processes of heavy metals in the soil environment,which is of great significance for ensuring the safety of agricultural products and formulating strategies for soil pollution prevention and control.Based on this,the impacts of microplastics on the distribution,migration and bioavailability of heavy metals in soil were systematically reviewed,and the internal mechanism of microplastics affecting the migration and transformation of heavy metals in soil was expounded,in order to provide theoretical support for ensuring the safety of the soil ecological environment and promoting the green development of agriculture.
