【摘要】 随着我国工业化和城市化的快速发展,大气细颗粒物污染已经成为一个严峻的环境问题,表现为持续性灰霾天气在全国大范围的高频率发生。大气细颗粒物的化学成分非常复杂,与排放源和大气演化过程密切相关[1]。其中,有机组分的表征一直是分析化学的挑战[2]。本工作以多种高分辨率质谱为手段,对我国大气细颗粒物中有机组分进行详细分析,并研究有机气溶胶的来源和大气演化过程。更多还原

【Abstract】 Rapid industrialization and urbanization has led to an increase in air pollution in China, which is a serious environmental problem influencing visibility, air quality, regional and global climates and human health. The chemical composition of atmospheric fine particles is very complex and is closely associated with the emission sources and atmospheric evolution. In particular, characterization of the organic aerosol is a challenging analytical task. Here, we present a summary of the chemical characterization of organic aerosol in fine particles in China using mass spectrometry. We also discuss the sources and atmospheric evolution of organic aerosol.更多还原
