In this study, five different types of smoking spaces and non-smoking spaces were investigated in orderto discuss about tobacco odor leakage from smoking area. VVOCs, VOCs and aledehydes wereanalyzed for characterization of odor. Additionally, the isolation result has been identified bydetermining ETS markers (nicotine and 3-ethenylpridine) based on ISO1845.Determined compounds were quantified and categorized into 13 groups, concentration between thesmoking space and non-smoking space was compared. In the most case, the concentration innon-smoking space was lower than smoking space. However, it was observed that the concentration innon-smoking space wasnt so low in stink group (aldehydes, alcohols and organic acids). When it wascompared the group composition, the aldehydes group composition in non-smoking space was higherthan smoking space. Although the total compounds concentration is lower in non-smoking space,aldehydes might contribute to tobacco odor because of their low odor threshold.
