In this study, five different types of smoking spaces and non-smoking spaces were investigated in order to discuss about tobacco odor leakage from smoking area. VVOCs, VOCs and aledehydes were analyzed for characterization of odor. Additionally, the isolation result has been identified by determining ETS markers (nicotine and 3-ethenylpridine) based on ISO1845. Determined compounds were quantified and categorized into 13 groups, concentration between the smoking space and non-smoking space was compared. In the most case, the concentration in non-smoking space was lower than smoking space. However, it was observed that the concentration in non-smoking space wasn't so low in stink group (aldehydes, alcohols and organic acids). When it was compared the group composition, the aldehydes group composition in non-smoking space was higher than 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.
