Measurement techniques new progress of atmospheric fine particles
Journal Title: Energy Environmental Protection - Year 2023, Vol 37, Issue 2
Abstract
Atmospheric fine particle pollution has an important impact on regional environment, global climate and human health, so it has been one of the key and difficult points of air pollution prevention and control. In recent years, due to the continuous promotion of China's air pollution prevention and control plan, the problem of atmospheric fine particle pollution has been significantly improved, and the relevant measurement technology has also made considerable progress. In this paper, the development and application of atmospheric fine particle measurement technology in recent years are reviewed based on the information of physical and chemical parameters such as atmospheric fine particle number concentration, particle size distribution and chemical composition. For the measurement of fine particle number 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 the urban air low concentration scenario. For the measurement of fine particle size, it mainly involves single particle size and overall particle size spectrum analysis. The single particle size is mostly determined by electron microscopy and optical microscopy, and the particle size spectrum analysis is mainly determined by electro migration classification. For the component measurement of fine particles, aerosol mass spectrometry and spectral analysis are mainly used. Finally, in view of the new requirements of research on the evolution mechanism of atmospheric particulates and intelligent monitoring and supervision, this paper discusses the future development of atmospheric fine particulates in multi-parameter comprehensive characterization, rapid measurement of dynamic processes, high-performance micro-nano sensors and other directions.
