Impact of Reactive Halogen Species on the Air Quality in California Coastal Areas

摘要

Air pollution in coastal urban areas remains one of the most serious environmental challenges in the State of California. Urban airshed models, which have been the basis of the development of air pollution mitigation strategies for many years, depend on the accurate description of the relevant chemical mechanisms. Therefore, it is crucial to determine whether the current chemistry in these models is complete, or whether new species and their reactions should be included. The primary goal of this project was to provide experimental evidence for the presence of reactive halogens, reactive halogen precursors, and halogen chemistry in coastal air masses and in the Los Angeles Basin to determine whether halogen chemistry should be included in current urban airshed models of Southern California.
