We conducted chemical characterization and source apportionment of PM2.5 in Hong Kong. Secondary formation was the leading contributor to organic carbon (OC) throughout the year. NOx processing played a key role in both daytime and nighttime secondary organic aerosol (SOA) production, and monoterpene SOA was the most abundant. Sulfate was positively related to total and secondary sulfate-related OC, and particle acidity was significantly correlated with SOC from aging of biomass burning.
