大气中的微塑料因其微小的尺寸、低密度、高稳定性、强大的吸附能力和复杂的表面结构,已经在全球范围内广泛分布.这些特性使微塑料对生态环境的影响范围极为广泛.文章介绍了大气微塑料的来源、分类、赋存特征,对样品采集、样品前处理及分析方法进行综述.目前应用于大气微塑料样品的采集方法有主动采样法和被动采样法,前处理的步骤主要有浓缩、消解和分离三个步骤,分析方法包括目视法、体视显微镜、扫描电子显微镜、傅里叶变换光谱法、拉曼光谱法、热裂解气相色谱-质谱法.文章总结了目前各种方法的优缺点和适用范围,并提出在今后的研究中必须创新溯源方法.
Research Progress on Sample Collection and Analytical Methods of Microplastics in Atmosphere
The microplastics in the atmosphere,due to their minuscule size,low density,high stability,strong adsorption capacity,and complex surface structure,have been widely distributed globally.These characteristics make the impact of microplastics on the ecological environment extremely broad.In this paper,the source,classification and occurrence characteristics of AMPs were introduced,and the sample collection,sample pretreatment and analysis methods were reviewed.The collection method of AMPs includes active sampling and passive sampling,the main processing of pretreatment mainly include concentration,dissolution and separation,and the main analysis methods include visual method,stereomicroscope,scanning electron microscope,Fourier transform spectroscopy,Raman spectroscopy,and pyrolysis gas chromatography-mass spectrometry.This paper summarizes the advantages and disadvantages of various methods and their applicable scope,and points out that it is urgent to innovative traceability method in future research.
