大气二次气溶胶形成过程的实验室研究进展

Research Progress on Laboratory Studies on Formation of Atmospheric Secondary Aerosols

大气污染中的二次气溶胶是我国灰霾污染中的主要的成分,其形成机制是大气环境领域的研究热点。文中阐述了大气污染中二次气溶胶的基本概念、来源和分类,通过其来源不同分为二次有机气溶胶和二次无机气溶胶。此外,明确了二次气溶胶在大气环境中非均相反应的形成机制研究的重要性,阐明实验室研究中气象要素的改变对二次气溶胶生成过程的影响,并对大气环境治理提供对策建议。

Secondary aerosol was the main component of haze pollution in China,and its formation mechanism was a research hotspot in the field of the atmospheric environment.The basic concept,source and classification of secondary aerosols in air pollution were described.Secondary aerosols can be divided into secondary organic aerosols and secondary inorganic aerosols according to their sources.Moreover,the importance of the formation mechanism of secondary aerosols in atmospheric environment was clarified.The influences of the change of meteorological elements on the formation process of secondary aerosol were emphasized in the laboratory.It also provided countermeasures and suggestions for the treatment of the atmospheric environment.
