摘　　要：在环境水体中,微塑料的吸附能力、迁移能力强,具有生物富集性,是一种具潜在风险的新型污染物。由于水体环境复杂而微塑料颗粒通常极小,分析鉴定是目前开展研究工作的瓶颈。通过文献收集和归纳,文中介绍了近年来水中微塑料的样品采集、分级分类提取以及成分鉴定分析等方法,系统地阐述了显微傅里叶变换红外光谱(micro-FTIR)在微塑料分析中的应用性与可瞻性。通过分析各类方法适用性、局限性,总结得出适用于水环境微塑料分析的全流程分析方法,为今后开展环境水体中微塑料赋存特征、迁移转化规律以及潜在环境风险等研究工作提供基础。The microplastics in environmental water body has strong adsorption,migration and bioaccumulation capabilities,and have become a class of emerging pollutants with potential risks.However,the complex environmental water body and the extremely small size of microplastics particles represent the great obstacles to comprehensively assess the loads of microplastics.Through literature collection and summarization,the paper reviews the methodologies used for collection,classification,extraction,component identification and quantification of microplastics in environmental water body,and systematically describes the application and prospect of micro-FTIR in the analysis of microplastics.Besides,in this paper,the applicability and limitations of various methods are evaluated.The whole process of analyzing microplastics in environmental water body is summarized,which contributes to the future researches on the characteristic,migration and transformation regularity,and potential environmental risk of microplastics in environmental water body.
