Short summary

The composition and light-induced evolution of a water-soluble organic carbon mixture from fresh biomass burning aerosols was investigated with direct infusion electrospray ionisation high-resolution mass spectrometry (HRMS) and liquid chromatography coupled with HRMS. Our findings indicate that the water-soluble organic fraction of combustion-derived aerosols has the potential to form more oxidised organic matter, contributing to the highly oxygenated nature of atmospheric organic aerosols.
