Short summary
Through lab tests and field measurements from typical sources, we found that carbonyl compounds from biomass burning are an order of magnitude higher than those from vehicles. The formation of carbonyl compounds in solid and liquid fuel is governed by combustion temperature and emission standards, respectively. Fuel type determines the chemical composition. Biomass burning and farm machinery are key drivers of atmospheric oxidation capacity. This study provides actionable solutions to safeguard public health.
