Short summary
Residential wood combustion emits large amounts of organic compounds, which are transformed in the atmosphere via photochemical ageing reactions. We assessed this organic emission at various stages of exposure with an oxidation flow reactor. Ageing led to major changes in both gaseous and particulate phases including increased acidic compounds and transformation of the polycyclic aromatic compounds. Such changes have serious implications for the health- and climate-related effects of combustion.
