The purpose of this paper is to present an experimental setup developed to characterizereactions between ozone and building products and document their potential impact on indoorair quality. Preliminary experiments were conducted on four building products: two carpets, agypsum board and a pine wood board. These preliminary experiments clearly indicate thatozone is significantly removed in contact with the four selected products. Measured ozoneremoval were around 65% for the two carpets, 70% for the gypsum board and 75% for thepine wood board. In case of exposure to ozone, emissions of building products were modifiedand reaction products (mainly carbonyl compounds) have been identified. For instance, whenexposed to ozone, the carpet with PVC backing shows higher emissions of formaldehyde, thecarpet with textile backing emits nonanal and decanal and the pine wood board exhibitsincreased emissions of hexanal.
