Abstract:Atmospheric fine particle pollution has an important impact on regional environment, globalclimate and human health, so it has been one of the key and difficult points of air pollution preventionand control. In recent years, due to the continuous promotion of China's air pollution prevention andcontrol plan, the problem of atmospheric fine particle pollution has been significantly improved, andthe relevant measurement technology has also made considerable progress. In this paper, the develop⁃ment and application of atmospheric fine particle measurement technology in recent years are reviewedbased on the information of physical and chemical parameters such as atmospheric fine particle numberconcentration, particle size distribution and chemical composition. For the measurement of fine particlenumber concentration, it mainly includes diffusion charge counting and condensation particle counting.The former is mainly applicable to the combustion emission scenario, and the latter is applicable to theurban air low concentration scenario. For the measurement of fine particle size, it mainly involves singleparticle size and overall particle size spectrum analysis. The single particle size is mostly determined byelectron microscopy and optical microscopy, and the particle size spectrum analysis is mainly deter⁃mined by electro migration classification. For the component measurement of fine particles, aerosolmass spectrometry and spectral analysis are mainly used. Finally, in view of the new requirements of re⁃search on the evolution mechanism of atmospheric particulates and intelligent monitoring and supervi⁃sion, this paper discusses the future development of atmospheric fine particulates in multi-parametercomprehensive characterization, rapid measurement of dynamic processes, high-performance micronano sensors and other directions.
