Aerosols have been shown to negatively impact the climate and public health. Alkyl amines may also be linked to the formation of aerosols. Animal feeding operations emit both amine and reduced sulfur compounds. The goal of this experiment was to determine the identity and concentrations of nitrogen and reduced sulfur emissions from these reactions. Trimethylamine was reacted with reduced sulfur compounds (hydrogen sulfide, methanethiol, and DMDS) in the presence of hydroxyl radical. Water soluble ions were analyzed with a Particle Into Liquid Sampler-Ion Chromatographs (PILS-IC) system. All three reactions produced reaction products, including ammonium and trimethylammonium salt particles. The reaction with DMDS additionally yielded methylammonium and dimethylammonium salts.
