In this study, a wide range of volatile organic constituents of environmental tobacco smoke (ETS) were determined using an environmental chamber, where ETS is the sole source of target compounds. ETS was generated in an environmental chamber by a number of different cigarettes, including the Kentucky reference cigarette and eight different commercial brands. More than 30 compounds were measured simultaneously for a total of twelve experimental runs. The target compounds are classified into three major classes, i.e. vapor phase ETS markers including 3-ethnylpyridine (3-EP) and nicotine, carbonyl compounds including formaldehyde, and volatile organic compounds (VOCs). The results from the chamber study were used to generate characterized ratios of selected VOCs to 3-EP, a vapor phase ETS marker. Emission factors for VOCs associated with ETS were also estimated. The characteristic ratios appeared to be generally in good agreement with published data obtained by environmental chamber studies similar to this study. This implies that the ratios may be useful for identifying and quantifying the impact of ETS as a source of target compounds in 'real world' indoor environments, which is affected by a complex mixture of multi-sources. The environmental chamber method described here provides a direct and reliable method to compare the ETS generated by different cigarettes. The method can also be applied to the simultaneous determination of many different ETS components.

Exposure to environmental tobacco smoke(ETS) increases the risk of lung cancer and other diverse health effect for nonsmokers. Health risk assessment of nonsmokers related to ETS exposure requires large and exact data of ETS exposure to nonsmokers. This study presented the data of ETS exposure to workers at three category of restaurants(Korean restaurant, coffee shop, wine shop) in Seoul. Markers of ETS exposure measured in this study were area and personal NO$_2$, area and urine nicotine, area respiratory suspended particulate(RSP) and urine cotinine. The mean concentration of RSP and nicotine of all restaurant indoor samples was 177.8$\mu\textrm{g}$/㎥(range:75.3~317.0$\mu\textrm{g}$/㎥) and 7.8$\mu\textrm{g}$/㎥(range:0~57.3$\mu\textrm{g}$/㎥). The mean concentration of urine cotinine measured for the biomarker of ETS exposure was 77.3ng/mL(range:17.3~174.6ng/mL). In all measurements, the concentration of ETS markers at the wine shop was higher than those at other restaurants. The correlation coefficient among the ETS markers measured in the study was significant between area RSP and nicotine concentration and between area NO$_2$and nicotine concentration.

Objectives: Thirdhand smoke (THS) refers to residual tobacco smoke pollutants that remain after cigarette smoking. The purpose of this study was to determine predictors of the belief among adults in Korea that THS is harmful to children. Methods: A population-based sample of 3,000 adults (${\geq}19$ years) among a web-based panel in Korea was obtained in November 2016. The respondents filled out questionnaires, including THS beliefs, smoking status, presence of voluntary smoke-free rules at home, and support for the implementation of smoke-free regulations at home. THS beliefs were assessed with a statement that staying in a room today where people smoked yesterday can harm the health of children. Results: Overall, 92.2 % of adults believed that THS exposure could harm the health of children. Respondents who were nonsmokers, believed that SHS exposure were associated with pneumonia of children, lived in home with complete smoke-free rule at home, and supported the implementation of smoke-free regulation at home were more likely to believe that THS could harm for health of children. Conclusions: The majority of Korean adults believed that THS exposure could harm the health of children. Predictors identified in the study can be useful to address the risk of THS beliefs and promote implementation of tobacco control policies.

인류가 흡연을 시작하면서 담배는 보편적인 사람들의 기호식품으로 이용되기도 했으나, 보건학적으로 인간의 건강을 위협하는 가장 위협적인 존재로 인식되고 있다. 흡연자의 담배연기에 비흡연자가 무저항적으로 노출되는 간접흡연의 문제는 생활수준의 향상과 생활활동 양식의 변화, 건강에 대한 관심의 증대로 현대인들에게 매우 중요한 문제가 되고 있다. 환경중 담배연기(Environmental Tobacco Smoke; ETS)는 흡연자의 입, 비강에서 품어내는 주류연(mainstream smoke)과 담배가 자연 연소되면서 발생하는 부류연(sidestream smoke)이 환경공기 중에 확산된 상태의 담배연기를 일컫는 용어로 실내공기의 주요오염원이다.

An important and somewhat under-emphasized issue in assessing the risk potentially associated with exposure to ETS is the reliability and objectivity of the methods used to measure the actual level of exposure. Objectivity of the science is crucial in this context since this topic tends to elicit strong social, emotional and political responses among the general public and the scientific community alike. This mini-review compares the strengths and limitations of various methods used in determining ETS exposure in scientific investigations. Methods reviewed include: questionnaire, area monitoring, bio-monitoring, and personal monitoring. In particular, results of several recent studies (conducted in the United States, Europe, and the Far East) using personal monitors in combination with questionnaire and bio-monitoring, which contribute to a more reliable, objective and realistic estimates of a person's actual exposure to 575, are discussed.
