Short summary

We investigated the light absorption, fluorescence, and molecular composition of dissolved organic carbon from the simulated combustion of biomass and coal and vehicle emissions with UV–vis spectra, EEM-PARAFAC, and FT-ICR MS. We observed high light absorption capacity from source emissions, and fluorescence spectra and molecular structures varied by source. We concluded that an EEM- and molecular-composition-based methodology could be helpful in the source apportionment of atmospheric aerosols.
