Abstract

We investigated air environment in two smoking rooms. Measurement items were carbon monoxide concentration, carbon dioxide concentration, dust concentration, gas sensor value, and odor measurement value by olfaction. Although dust concentration and carbon monoxide concentration declined at the time of un-smoking, Odor measurement value by olfaction did not decline. Therefore, we examined the evaluation index which is related to olfactory sense. As a result, odor measurement value by olfaction and n-valeraldehyde concentration had correlation in the smoking room at the time of un-smoking.
