Heterogeneous reactions of amines have been recently shown to play an important role in the formation and transformation of atmospheric aerosols. This presentation summarizes the latest laboratory progress on the multiphase chemistry of amines. Particular emphasis is given to the contributions of amines to new particle formation, growth of submicron particles, and alteration in the physiochemical properties of pre-existing particles, including hygroscopicity, thermostability, density, phase, and optical properties, from exposure to gaseous amines. We will discuss the atmospheric implications of the multiphase reactions of amines, including the potential impacts on direct and indirect climate forcing of aerosols, and future research directions.
