Short summary
Biomass fuels used for domestic purposes in east Africa produce a significant atmospheric burden of aerosols and volatile organic compounds. The chemical properties and composition of these aerosols have not been investigated in the laboratory. In this work methanol extracts from filter samples of aerosol collected from an indoor smog chamber were analyzed to determine the chemical composition and identify the light absorption properties of organic aerosol constituents.
