【摘要】 塑料制品在为我们提供了极大的便利的同时，也给我们生活的环境造成了极大的污染，其中微塑料已经在海洋、土壤、江河、大气等等不同的环境场景中被检出。利用显微红外光谱技术，检测了室内空气沉降物中的微塑料，鉴定出了微塑料的成份种类有纤维素，聚酰胺等，同时，利用显微镜的可视化功能，获取了同微塑料外形及大概尺寸的信息，观察了不同类型微塑料的形貌特点，为快速检测、鉴定空气沉降物中微塑料的类别提供可靠的方法参考，也为室内空气环境质量的评价提供参考数据。更多还原

【Abstract】 Plastics products provide us with great convenience, meanwhile, cause great pollution to our living environment. Microplastics have been detected in different environmental scenes such as the ocean, soil, rivers, atmosphere, etc. In this paper, micro infrared spectroscopy was applied to evaluate the microplastics in indoor air sediments. The result showed that the components of microplastics include cellulose, amide and polyethylene etc. Using the visualization function of microscope, the information about the shape and approximate size of the microplastic was obtained. It provides a reliable method reference for rapid detection and identification of microplastics in air sediments. It also provides reference data for the evaluation of indoor air quality.更多还原
