沉淀物中微塑料研究进展

Summary of Research Methods on Microplastics in Sediments

指出了微塑料是尺寸介于0.2~5.0mm不同形态塑料的统称。如今我国对微塑料污染的研究已经开展起来,但是尚处于起步阶段,研究的内容与成果都较于局限。而国际社会对此也没有对微塑料分离分析提纯方法达成共识,建立统一的标准。因此,建立准确、高效的微塑料分析方法十分必要。总结了微塑料采集、预处理、分离等研究方法,针对现阶段微塑料分析方法存在的问题和不足,提出了进一步研究的方向。

Microplastics is a collective name for different forms of plastic with dimensions ranging from 0.2~5.0 mm.Nowadays,research on microplastics pollution in China has been carried out,but it is still in its infancy,and the research content and results are more limited.In addition,the international community has not reached a consensus on the purification and analysis of microplastics,and established a unified standard.Therefore,it is necessary to establish accurate and efficient microplastic analysis methods.This paper summarizes the research methods of microplastics collection,pretreatment,and separation.Aiming at the problems and shortcomings of microplastics analysis methods at this stage,further research directions are proposed.
