报告简介：Organic aerosols account for 20-90% of atmospheric fine particle mass. Enhanced characterization of the physical and chemical properties of organic aerosols will improve our understanding of their effects on environment, climate, and human health. The formation and evolution mechanisms of organic aerosols, however, remain unclear, largely due to the highly complex nature of organic aerosols’ chemical composition. In this talk, a method for quantification of organic functional group composition will be introduced. The application of this method in studying the sources and reaction mechanisms of bulk organic aerosols from field and laboratory experiments will be demonstrated. In addition, a single-particle organic aerosol functional group measurement technique will be discussed.
