Résumé

The potential for reactions among indoor pollutants to generate reactive and highly irritating products is a reason to maintain adequate ventilation rates and clean ventilation filters. Terpenoid (from recirculated air, a scenario common in the tropics) captured by ventilation filters can react relatively quickly with ozone which may lead to downstream air supply that contain oxidized terpenoid and this may be perceived to be less acceptable than outdoor air. The chemical composition (water solubility and chemical reactivity) of these particles strongly governs their toxicity. The composition determines either how the respiratory tract reacts or how the body responds. There are few studies examining the impact of the ventilation rate and ventilation filters on indoor chemistry. Studies documenting the effect of filters, ventilation and recirculation rate on ozone initiated chemistry in buildings utilizing recirculation of conditioned air are lacking. Thus, the need to stimulate research in this area to better understand the effect, recirculation of conditioned air phenomenon could have on indoor air quality serves as the motive for the quest for tropical research. The paper demonstrates that reaction between reactive gases to generate highly irritating products may even be more important in a mechanical ventilation system that utilizes recirculation of conditioned air.
