摘要
近年来,随着塑料生活制品及农田薄膜的大量使用,微塑料碎片或颗粒在土壤环境中的大量累积,危害着陆地生物健康和生态系统安全。研究陆地土壤生态系统中污染现状,可为今后土壤微塑料源解析及污染作用机制提供研究思路。文章综述了近年来我国农田土壤、湿地、河湖底泥等生态系统中微塑料的污染状况,分析了陆地土壤生态系统微塑料的来源及迁移,进一步讨论了微塑料长期累积对土壤理化性质、土壤生物的作用效应,并展望了未来应着重研究的微塑料对土壤生态系统功能的影响及土壤植物-动物-微生物对微塑料的降解途径等。
In recent years,with the extensive use of plastic household products and farm films,microplastic fragments or particles accumulate in the soil environment,endangering the health of terrestrial organisms and the safety of the ecosystem.Research on microplastics pollution status in terrestrial soil ecosystem can provide research ideas for the source analysis and pollution mechanism of soil microplastics in the future.In this paper,the microplastics pollution status of the farmland soil,wetlands,lakes sediment in the ecological system were reviewed.The source and migration of the micro plastic land soil ecosystem were analyzed,and the micro plastic accumulated over a long period of time the effects of soil physical and chemical properties,soil organisms were further discussed,and the future study should focus on the micro plastic effect on soil ecosystem function and soil,plant,animal,microbial degradation pathways of micro plastic,etc were put forward.
