Full-scale chamber of test house was used to investigate emission data of sesqui-terpenes from cedarwood. This experiment involvedplacing samples of cedarwood and an ozone generator in one room of the test house. The sesqui-terpenes were identified. The indoor sesqui-terpenes concentration with ozone emission was much lower than that without ozone emission. It was found that the higher the indoor ozone concentration, the lower the sesqui-terpenes concentration. The sesqui-terpenes might have been consumed by the reaction with ozone during the experiment. The concentrations of formaldehyde (HCHO) were not changed regardless of the change of ozone concentration. HCHO is not expected to be formed by the reaction between ozone and the major sesqui-terpenes emitted from cedarwood.
