Short summary
Heterogeneous oxidation of SO2 is suggested to be one of the most important pathways for sulfate formation during extreme haze events in China, yet the exact mechanism remains highly uncertain. Our study reveals that ubiquitous compounds at the sea surface PAHS and DMSO, when exposed to SO2 under simulated sunlight irradiation, generate abundant organic sulfur compounds, providing implications for air-sea interaction and secondary organic aerosols formation processes.
