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.
