Considering the chemical reaction of VOC generated indoors and the ozone contained in the outdoor air brought by ventilation, reaction products, e.g., ultra fine particles and odorants, might be formed by the chemical reaction. The purpose of this study is to investigate the effects of chemical reaction between ozone and VOCs emitted from cedar wood on the perceived air quality. The olfactory panel assessed perceived air quality using odor intensity scale, acceptability scale and odor quality scale. VOCs concentrations were measured with GC/MS system. After ozone generation, the voted average odor intensity did not elevated significantly. However the percentage of dissatisfied subjects showed 50% or more after ozone generation, while it was almost 0% before ozone generation.
