土壤微塑料污染及生物降解研究进展

Research Progress on Soil Microplastic Pollution and Biodegradation

塑料污染一直是环境治理所面临的重大问题和挑战,其含量多且降解能力弱。微塑料是塑料由于各种原因而形成的小颗粒。微塑料作为近年来发现的一种新型污染物,由于其颗粒小而不易被发现,严重威胁着自然生物群落和人类公共健康,已成为全球性的挑战。当前对于微塑料的研究主要集中于水生生态系统上,而对于陆地生态的研究却相对较少。该综述主要对微塑料的陆地危害及研究进展进行总结,探究了在土壤环境中微塑料所引发的问题及危害,以及对微塑料的生物降解研究展开分析,对未来土壤环境中微塑料生物降解的发展前景进行展望。

Plastic pollution has always been an important issue and challenge for environmental management on account of its large amount and weak degradation capacity.Microplastics are small particles formed by plastics for various reasons.As a new pollutant found in recent years,microplastic has become a global challenge becausetits particles that are small and difficult to be found,which seriously threatens the natural biological community and human public health.At present,the research on microplastics mainly focusd on aquatic ecosystem,but the research on terrestrial ecology was relatively few.This review mainly summarizes the land hazards and research progress of microplastics,explores the problems and hazards caused by microplastics in soil environment,analyzes the research on the biodegradation of microplastics,and finally prospects the development prospect of microplastics biodegradation in soil environment in the future.
