Abstract

<p>In this study, we examined odor components in smoking rooms for use in determining an evaluation index for the odor. We measured the concentrations of substances with specified offensive odor, concentration of acetic acid,odor intensity, hedonic, and odor concentration in smoking rooms with a smoke separating equipment and a ventilation fan.</p><p>The results are as follows:</p><p>(1) Odor evaluation after a certain period of non-smoking by smoker panels showed an odor concentration of 32 and an odor intensity of about 2.5. This value is equal to or higher than the cognitive threshold value.</p><p>(2) Acetaldehyde concentration could be used as the index of sensory evaluation in the period of smoking, but not during the period of non-smoking.</p><p>(3) The n-valeraldehyde concentration could be measured in correspondence with the odor sensory evaluation during the periods of both smoking and non-smoking. Therefore, it was suggested that n-valeraldehyde be used as an evaluation index for the odor in smoking rooms, because it can also be measured during the period of non-smoking.</p>
