A Molecular-Level Approach For Characterizing Water-Insoluble Components Of Ambient Organic Aerosol Particulates Using Ultrahigh-Resolution Mass Spectrometry, A. S. Willoughby, A. S. Wozniak, Patrick G. Hatcher

Chemistry & Biochemistry Faculty Publications

The chemical composition of organic aerosols in the atmosphere is strongly influenced by human emissions. The effect these have on the environment, human health, and climate change is determined by the molecular nature of these chemical species. The complexity of organic aerosol samples limits the ability to study the chemical composition, and therefore the associated properties and the impacts they have. Many studies have addressed the watersoluble fraction of organic aerosols and have had much success in identifying specific molecular formulas for thousands of compounds present. However, little attention is given to the water-insoluble portion, which can contain most of …
