N2 - In this study we elucidated the effects of applying alcohol to wood on chemical emissions, including those of acetaldehyde, and perceived air quality. Simulating the amount of alcohol used to clean objects indoors, 130 mL of alcohol per square meter was applied to three materials-cypress, Japanese cedar, and stainless steel-and chemical emission rates were determined using a test chamber method. When alcohol was applied to cypress and Japanese cedar, the amount of acetaldehyde released was more than 300 times higher than that released when alcohol was applied to stainless steel, with a maximum of 9, 327 μg/m3. In odor evaluations, indoor air tolerance was higher than the standard indoor air conditions when alcohol was applied to the wood. Hence, we consider that the application of alcohol to wood deteriorates the indoor air environment but humans do not perceive any harmful effects thereof.
