IMPACT DES COMBUSTIONS DU BOIS DE CHAUFFAGE SUR LES ATMOSPHERES EXTERIEURES ET INTERIEURES.
ETUDE DE LA DEGRADATION D'UN TRACEUR SPECIFIQUE EN ENCEINTE DE SIMULATION : LE CREOSOL

Abstract : Currently, few studies related to Volatile Organic compounds (VOC) emissions in indoor air were realised from combustion sources (heating, cooking ...). Indeed, the use of fireplaces will increase next years due to oil price: wood valorisation is one of the alternative sources for residential heating. There are not many studies about this subject because analytical techniques to determine weak concentration are difficult to implement. The main goal of this work is to evaluate the impact of VOC emissions due to wood combustion, and more particularly in indoor air. In order to understand the role of compounds emitted on air quality, a kinetic study of a specific marker was carried out in an atmospheric simulation chamber.Thus, after having studied the possibilities of news analytical supports containing carbon nanostructures (CNS), we evaluated VOC emissions from different wood fireplace. This study showed it was possible to find a marker in relation to wood type burning.Creosol was highlighted as this marker and its kinetic study showed that it was very reactive (very high constant). This compound was also at the origin of secondary compounds sometimes more toxic for human health. Finally at this time the CNS showed unequalled analytical qualities and requires complementary studies for a reliable analytical application
