Short summary
We stimulated the photochemical aging of organic film coated on aqueous aerosol in the presence of imidazole-2-carboxaldehyde, humic acid, an atmospheric PM2.5 sample, and a secondary organic aerosol sample from the lab. The unsaturated lipid mixed with photosensitizer under UV irradiation produced hydroperoxides, leading to surface area increase in organic film. Our results reveal the modification of organic film on aqueous aerosol has potential influence on the hygroscopic growth of droplets.
