Household products and indoor air quality : emission, reactivity and byproducts in both gaseous and particulate phases

Abstract : The present work investigates Secondary Organic Aerosols (SOA) formation in indoor environment from VOCs ozonolysis emitted by housecleaning products. For each of the 54 housecleaning products tested physical characterisation of particles has been investigated. Cleaning products, containing high level of terpenes and derivates, have been extensively studied in the occupational house MARIA (Maison Automatisée pour des Recherches Innovantes sur l'Air) allowing simulation of realistic use conditions and exposure. Important formation of AOS and strong increment of particle number was observed upon their use for at least 1 hour, on-line chemical composition were followed using an AMS-c-TOF (Aerosol Mass Spectrometer Compact Time-of-Flight). Chemical speciation of both gas and particulate phases were additionally carried out by simultaneous sampling on sorbent tubes and filters has been performed. The molecular composition of oxygenated species was investigated using derivatisation prior to thermal-desorption coupled with gas chromatography and mass spectrometry (TD-GC-MS) analysis.
