In western countries, where people spend most of their time in confined areas, indoor air quality is recognized as a public health issue. Among multiple indoor air pollution sources (building materials, furniture, heating) the use of housecleaning products is still poorly characterized. It is well known that limonene, a good Secondary Organic Aerosols (SOAs) precursor towards ozonolysis (Chen and Hopke, 2010), is widely employed in scented products such as freshener and household cleaners (Nazaroff and Weschler, 2004). Besides, indoor ozone levels can be high enough to initiate gas phase chemistry (Weschler, 2000) and possibly to lead to the formation of indoor secondary products which may be of health concern. Investigations are therefore necessary to characterize the chemical composition of particles and gases formed during housecleaning use and to evaluate real population exposure. The ADOQ project (Activités DOmestiques et Qualité de l'air intérieur) aims at identifying and quantifying VOCs, SVOCs and particles emitted and/or secondarily formed consequently to the use of housecleaning products. In the frame of this project, emissions of 54 housecleaning products representative of domestic activities have been characterized using an emission test chamber. The housecleaning products displaying the most intense VOCs emission (particularly limonene) have been selected and tested in real indoor conditions inside the experimental house MARIA (Maison Automatisée pour des Recherches Innovantes sur l'Air).
