Short summary
This study investigates the molecular characteristics and chemical evolution of organic aerosol (OA) in contrasting urban and seaside environments by offline Chemical Ionization Mass Spectrometry. Urban OA was enriched in aromatic species, while seaside OA featured aliphatic and highly oxidized compounds. Marine-derived humid air masses promoted aqueous/heterogeneous phase OA formation, leading to a higher oxidation state.
