Atmospheric amines – Part III: Photochemistry and toxicity

Approximately 150 amines have been identified in the atmosphere but relatively little is known about their atmospheric photochemistry. In Part I and II of this work (Ge et al., 2011a and Ge et al., 2011b), the present knowledge of the sources, fluxes, and dynamics of atmospheric amines was reviewed based upon a survey of the literature. In this work we compile published data for the gas phase atmospheric reaction rates of amines and products from these reactions. All available amine photochemical reaction data are summarized including reaction rates with OH, O3, NO3 radicals, and Cl atoms and photolysis. Toxicity and atmospheric lifetime of these amines and their reaction products are also reported with the goal of estimating of potential health hazards of atmospheric amines.
