|The Surratt Lab utilizes advanced mass spectrometry and chromatographic techniques to understand as deeply as possible the atmospheric chemistry that occurs in both the gas and particulate phases, with special focus on the chemistry leading to the formation of secondary organic aerosol (SOA). Since numerical models currently underestimate the amount of SOA mass observed in fine aerosol collected from several locations, which indicates that significant sources of SOA are not yet identified or well characterized, we will chemically characterize both smog chamber-generated and ambient SOA in order to more adequately describe sources (e.g., heterogeneous chemistry) of SOA in the troposphere. By using this approach, Professor Surratt has helped to elucidate the chemical pathways leading to organic aerosol formation from the atmospheric oxidation of isoprene, which is the most abundant non-methane hydrocarbon emitted annually into the Earth’s atmosphere that was previously thought not to be a significant source of SOA. Our chemical measurements will also be coupled with toxicological data in order to asses the impact of fine aerosols on human health. Key Words: air quality, heterogeneous chemistry, air pollution, organic aerosol|
