Research Progress on Analysis,Environmental Behavior and Ecological Risks of Microplastics in Soil
As emerging persistent pollutants,microplastics cause global environmental problems that cannot be ignored.Research on microplastics pollution in soil is lagging and lacking compared in water environment.This paper reviews the research progress of source,analytical method,environmental behavior,and ecological effects of microplastics in soil environ-ment and urgent problems of microplastics in soil environment.The source and input path of microplastics in soil were introduced in detail.The separation and analysis methods of microplastics in soil and the advantages and disadvantages were summarized.The environmental behavior of microplastics in soil was analyzed,including migration,degradation and interaction with other pollutants in soil.The ecological effects of microplastics in soil were described,including the effects on soil physi-cal and chemical properties,soil microorganisms,soil animals and plants.The future research directions and emphases on microplastics in soil environment were prospected.The source control of microplastics in soil,the law and mechanism of interaction with other pollutants,and the risk assessment of combined pollution on human health are the difficulties and focuses in future research.
