Impact of wood burning on outdoor air quality : Existing French data current studies. Contribution du chauffage au bois à la qualité de l'air extérieur : données existantes et études en cours en France
Résumé
French source apportionment studies of air quality including the wood combustion source become widespread. Quantify a single source contribution to air quality requires to be provided with a specific measurable data to this source. For that reason, numerous studies have focused on the determination, in the atmospheric samples, of the source-specific compounds, usually called molecular tracers. Since 2000, trend works focused on the "wood combustion" contribution to air quality have been based on the use of some tracers such as levoglucosan and metoxyphenols. Obtained results have been compared to atmospheric particles global characteristics : organic carbon (OC), elementary carbon (EC), PM10, PM2.5 and polycyclic aromatic hydrocarbons (PAH). The results presented in this article show not only the interest but also the limits of such an approach, as well as the need to develop and complete the current studies in order to quantify the different sources contribution to air quality.
