Short summary
The overall characteristics and concentrations of organosulfates (OSs) and nitrooxy-OSs (NOSs) were determined in summer in Beijing. This study provided direct observational evidence that OSs form via acid-catalyzed aqueous-phase reactions in the presence of acidic sulfate aerosols, and monoterpene NOSs form via nighttime NO3 oxidation. Using OSs and NOSs as examples, this work highlights the formation pathways of SOA via anthropogenic–biogenic interactions and organic–inorganic reactions.
