Short summary
This study reveals the sulfate formation in photosensitized particles from biomass burning under UV and SO2, of which the relative atmospheric importance in sulfate production was qualitatively compared to nitrate photolysis. On the basis of single-particle aerosol mass spectrometry measurements, the number percentage of sulfate-containing particles and relative peak area of sulfate in single-particle spectra exhibited a descending order of 3,4-dimethoxybenzaldehyde > vanillin > syringaldehyde.
