Limonene is widely employed in scented products used in indoor environments such as fresheners and household cleaners (Nazaroff 2004). It also displays one of the highest potential for the formation of Secondary Organic Aerosols (SOAs) following ozonolysis (Jaoui 2006; Chen 2010). Besides, indoor ozone concentration, influenced by outdoor concentration and indoor sources, can be quite important to initiate gas phase chemistry (Weschler 2000) and possibly lead to secondary products formation. This work investigates SOAs formation from the ozonolysis of limonene as emitted from a detergent, in order to gather information on aerosols that are an important source of exposure for people using household products.
