Human activities release large amounts of anthropogenic pollutants into the air, and thereby produce substantial secondary organic aerosol (SOA). Aromatic hydrocarbons (AHs) that mainly emitted from coal combustion, transportation, solvent use and biofuel/biomass burning, are a major class of anthropogenic SOA precursors. At present, there are few field studies focusing on AH-derived SOA (SOA) on a continental scale, especially in polluted regions of the world.

- Isoprene significantly contributes to secondary organic aerosol (SOA), with its formation influenced by human emissions, yet information on isoprene SOA in polluted areas is limited.
- A year-long study across 12 sites in China revealed that SOAI tracers show higher concentrations in rural areas from the HO2-channel and in urban zones from the NO/NO2-channel.
- The research indicated that summer SOAI levels were mainly driven by biogenic emissions, while winter increases were linked to biomass burning, highlighting regional differences in isoprene sourcing and SOAI formation in polluted areas.
