Abstract In the context of climate change, it is in France a will of its Environmental Agency (ADEME) to strongly push for biomass burning as an alternative source of energy to heat residential homes. In order to limit the consequences in terms of air quality, ADEME offers financial incentives for home owner to install new and cleaner wood stoves. However biomass burning is known to be a dominant source of particulate matter (PM). In addition the emissions from biomass burning like any combustion processes can contain a significant amount of light absorbing carbonaceous aerosol and carcinogenic compounds such as Polycyclic Aromatic Hydrocarbons (PAHs). To better understand the impact on our health and the potential effect these emissions may have on climate, it is important we quantify and characterize them at best. Here were characterized and compared the primary emissions factors of different residential woodstoves technologies (two traditional logwood stoves and one pellet stove) using a variety of tree species including beech, ash, maple and spruce. Biomass burning emissions were analyzed by TAG (Thermal Desorption Aerosol Gas Chromatograph) coupled with a HR-ToF-AMS (High Resolution – Time of Flight – Aerosol Mass Spectrometer), an Aethalometer AE33 for the refractory fraction of the particulate phase and a PTR-ToF-MS (Proton Transfer Reaction – Time of Flight – Mass Spectrometry) for the gaseous phase. Molecular identification was further investigated through GCxGC EI-HF ToF MS analysis performed on quartz filter samples. A hundred of fine particle organic compounds were detected and quantified. Implications in terms of air quality improvement and source apportionment is also discussed.
