Experimental study of reactions between ozone and building products
Résumé
The purpose of this paper is to present an experimental setup developed to characterize reactions between ozone and building products and document their potential impact on indoor air quality. Preliminary experiments were conducted on four building products: two carpets, a gypsum board and a pine wood board. These preliminary experiments clearly indicate that ozone is significantly removed in contact with the four selected products. Measured ozone removal were around 65% for the two carpets, 70% for the gypsum board and 75% for the pine wood board. In case of exposure to ozone, emissions of building products were modified and reaction products (mainly carbonyl compounds) have been identified. For instance, when exposed to ozone, the carpet with PVC backing shows higher emissions of formaldehyde, the carpet with textile backing emits nonanal and decanal and the pine wood board exhibits increased emissions of hexanal.
