Short summary

BSOA formation is affected by human activities, which are not well understood in polluted areas. In the polluted PRD region, we find that monoterpene SOA is aged, which probably results from high O_x and sulfate levels. NO_x levels significantly affect isoprene SOA formation pathways. An unexpected increase of β-caryophyllene SOA in winter is also highly associated with enhanced biomass burning, O_x, and sulfate. Our results indicate that BSOA could be reduced by lowering anthropogenic emissions.
