Enhancing characterization of organic nitrogen components in aerosols and droplets using high-resolution aerosol mass spectrometry

Abstract ON) compounds in aerosol particles and atmospheric droplets. To achieve this goal, we analyzed 75 N -containing organic compounds, representing a diverse range of ambient non-organonitrate ON (NOON) types, including amines, amides, amino acids, N heterocycles, protein, and humic acids. Our results show that NOON compounds can produce significant levels of NH x + NO x + CH 2 N + m/z  = N 2 + ± C n H 2 n + 2 N + CH 4 N + C 2 H 6 N + C 3 H 8 N + C n H 2 n NO + n C 2 H 4 NO 2 + C 2 H 3 NO + CH 4 NO + C x H y N 2 + N -heterocyclic compounds. Notably, an elevated abundance of NH 4 + NH 4 + PM 1 PM 1 N -containing aromatic heterocycle (e.g., imidazoles) and amides. These findings highlight the significant potential of employing the widespread HR-AMS measurements of ambient aerosols and droplets to enhance our understanding of the sources, transformation processes, and environmental impacts associated with NOON compounds in the atmosphere.
