Field straw residue burning is a widespread type of biomass burning in Asia, while its emissions are poorly understood. In this study, we designed lab-controlled experiments to comprehensively investigate the emission factors, chemical compositions and light absorption properties of both water-soluble and water-insoluble carbonaceous aerosols emitted from straw burning. The results clearly highlight the significant influences of burning conditions and combustion efficiency on the emissions.
