Short summary
This study investigated the evolution of biomass and water-soluble organic matter (WSOM) derived from coal combustion during an aqueous photochemical process. The results indicate that photochemical aging induces distinct changes in the optical and molecular properties of WSOM. More pronounced alterations were observed during OH photooxidation than direct photolysis. Our results also demonstrate that atmospheric photooxidation may represent a significant source of black-carbon-like substances.
