Global microplastic pollution has aroused an emerging concern, and in recent years, a variety of studies have focused on the concentrations of microplastics in different ecosystem. To date, standard methods for detecting microplastics have not been established, which impedes comparisons among the reported results from different studies. This review summarizes the current methods and technologies applied in sampling, extracting and identifying microplastics from the atmosphere. Passive atmospheric deposition and active pumped samplers are two general methods used to sample airborne microplastics. Stereomicroscope, FTIR, SEM, Pyr-GC/MS, and Raman spectroscopy are commonly employed for identification and quantification of microplastics. This review also discusses the limitations of these methods, and quality control for accurate results. This review provides a comprehensive summary of methods used for the detection of airborne microplastics and highlights the need to establish standard approaches in future research.

全球微塑料污染引起了人们的关注，近年来，各种各样的研究集中于不同生态系统中微塑料的浓度。迄今为止，尚未建立检测微塑料的标准方法，这妨碍了不同研究报告的结果之间的比较。这篇综述总结了目前在大气中采样，提取和鉴定微塑料的方法和技术。被动大气沉积法和主动泵送采样器是用于采样机载微塑料的两种通用方法。立体显微镜，FTIR，SEM，Pyr-GC / MS和拉曼光谱通常用于鉴定和定量塑料。这篇综述还讨论了这些方法的局限性，以及对准确结果进行质量控制的方法。
