  • Smoking of tobacco cigarettes is associated with a rise in blood pressure together with increase in heart rate. This study was aimed to examine the acute effect of tobacco and non-tobacco cigarette smoking on the blood pressure and heart rate by randomized crossover study. In the results, systolic/diastolic blood pressure and heart rate changes after smoking were significantly different between male and female group. Blood pressure and heart rate were elevated after smoking, but statistical significance for the difference was identified only in the female group. Because Non-tobacco smoke made from leaves of E. ulmoides has no nicotine, its effect on blood pressure and heart rate was negligible. Remarkable difference of heart rate changes in women was observed between tobacco cigarette smoking group and non-tobacco cigarette smoking group.

  • Adolescents exposed chronically to tobaccotobacco smoke have been found to have reduced pulmonary function as well as an increased risk of lung cancer and a serious heart disease. Consequently, reducing exposure to tobacco smoke is an important public health goal. This study was conducted to develope the exact evaluation method of student smoker or heavy exposure from ETS, and the change on smoking behavior and attitude after a stop-smoking program. From the study, we concluded that the cotinine concentrations in saliva from students indicate exactly whether they are smoker or not. Also, it was found that the more and exact informations from both the cotinine analysis and the questionnaire were obtained than from only the questionnaires. The non-smokers had more positive effects on the changes of cog-nitions, behaviors and attitude about passive-smoking after a stop-smoking program than the smokers. The results of this study show that through both the accurate determination of cotinine in saliva and the questionnaires, the smoking status and the tobacco education effectiveness can be predicted.

  • In this study, the concentrations of particulate organic constituents of environmental tobacco smoke(ETS) were determined using an environmental smog chamber, where ETS is the sole source of target compounds. ETS was generated in a 30 ㎥ environmental chamber by a number of different cigarettes, including the Kentucky 1R4F reference cigarette and eight commercial brands. A total of 12 experimental runs was conducted, and target analytes included a group of ETS markers both in vapor and particulate phase and a class of polycylic aromatic hydrocarbos(PAHs) associated with ETS particles. The mass concentrations of PAH in ETS particles were also determined. The average contents of benzo(a) pyrene and benzo(a) anthracene in ETS particles for the commercial brands were 12.8 and 21.5$\mu\textrm{g}$/g, respectively, There values are all somewhat higher than those determined previously by other studies. Results form the chamber study are further used to estimate the average and variability of cigarette yields for target compounds associated with ETS. Finally, ratios of RSP to the surrogate standards of UVPM, FPM and solanesol were calculated for each sample. The average conversion factors factors for the eight commercial brands were 7.3, 38, and 41 for UVPM, EPM, and solanesol, respectively. The UVPM and FPM factors are in good agreement with the recently published values. Whereas there might be a substantial difference in the solanesol content among cigarettes produced in different countries, the variability is somewhat greater than those of UVPM and FPM, Unfortunately, comparison of the PAH yield data from this study with literature values was complicated by a lack of consistency in cigarette smoke generating methodology. Validation of the PAH yields was also difficult due to a lack of information on the ETS related PAH in the literature. From and engineering viewpoint , however, these data on the cigarette yields of ETS components may still provide useful information to studies on the mathematical modeling of indoor air quality management regarding tobacco smoke as a source of interest, or to studies on the assessment of human exposure to ETS.

  • Allergic diseases such as asthma, allergic rhinitis, atopic dermatitis, and food allergy, are most common chronic, noncommunicable diseases in childhood. In the past few decades, the prevalence has increased abruptly worldwide. There are 2 possible explanations for the rising prevalence of allergic diseases worldwide, that an increased disease-awareness of physician, patient, or caregivers, and an abrupt exposure to unknown hazards. Unfortunately, the underlying mechanisms remain largely unknown. Despite the continuing efforts worldwide, the etiologies and rising prevalence remain unclear. Thus, it is important to identify and control risk factors in the susceptible individual for the best prevention and management. Genetic susceptibility or environments may be a potential background for the development of allergic disease, however they alone cannot explain the rising prevalence worldwide. There is growing evidence that epigenetic change depends on the gene, environment, and their interactions, may induce a long-lasting altered gene expression and the consequent development of allergic diseases. In epigenetic mechanisms, environmental tobacco smoke (ETS) exposure during critical period (i.e., during pregnancy and early life) are considered as a potential cause of the development of childhood allergic diseases. However, the causal relationship is still unclear. This review aimed to highlight the impact of ETS exposure during the perinatal period on the development of childhood allergic diseases and to propose a future research direction.

  • ETS concentrations in the PC game rooms and factors affecting ETS concentrations were measured. Nicotine, 3-EP, respirable dust and UVPM were used as tracers for ETS. ETS concentrations are 2-3 times higher than those of other results. The concentration of ETS at the commercial district was higher than that of the residential district. The correlations between these tracers and SD/ ACH, a factor affecting to ETS concentration, were calculated. The correlation between 3-ethenylpyridine among tracers and SD/ACH was highest. The correlation between respirable dust and SD/ ACH was lowest. It was difficult to recommend respirable dust as a tracer of ETS.

  • 비흡연자가 환경중의 담배연기를 흡입하게 되면 폐암유발 위험성을 증대시킨다는 주장이 미국, 유럽, 일본 그리고 몇몇 아시아 국가에서 제기되어 왔다. 본 논문에서는 한국에서 이러한 잠재위험성의 사실여부를 판단하는데 이용될 수 있는 현재까지의 과학적 근거를 제시하고 그에 대하여 토의하고자 한다. 잠재위험성의 성격, 환경중의 담배연기량에 대한 반응과 관련된 자료, 그리고 환경중 담배연기에 대한 실제적인 노출형태를 구분할 수 있는 자료 등이 토의된다. 잠재위험성에 대한 최종적인 판단은 한국의 공중보건정책의 기초로서 잠재위험성의 평가임무와 관련된 자격을 갖춘 사람들에게 맏겨질 것이다.

  • There has been increased interest in the health effects of the Environmental Tobacco Smoke(ETS) as a confirmed human carcinogen. It has been known to be extremely difficult to make an accurate assessment of exposure to ETS since it is consisted of a variety of components and there are a number of labile chemicals. Therefore, it is necessary to obtain, to interpretate and to provide the data of quantitative exposure assessment to ETS in the field of environmental health. The purpose of this research is to evaluate the concentration of ETS using VOC in indoor office environments. The correlations and concentrations of benzene, RSP, 3-EP, nicotine that are indicators for ETS were investigate with smoking density, air change per hour(ventilation rate). Air samples were taken in smoking room(7 sites), smoking allowed office (3 sites), corridor outside smoking room(7 sites), non-smoking office (9 sites). The concentrations of benzene showed significant difference according to category of indoor office environments. The geometric mean concentration of benzene were 23.56 ${\mu}{\textrm}{m}$/㎥(range 4.80~192.90 ${\mu}{\textrm}{m}$/㎥) in smoking rooms. 6.16 ${\mu}{\textrm}{m}$/㎥ in smoking allowed offices, 1.32 ${\mu}{\textrm}{m}$/㎥ in the non-smoking offices respectively. The ratios of the concentration of benzene between outdoor air and smoking room, smoking allowed office, and non-smoking indicators concentrations, SD, and SI were 0.82(benzene and nicotine). 0.76(benzene and RSP), 0.60(benzene and SD), 0.76(benzene and SI). It is proposed that benzene is a good indicator for ETS.

  • 담배의 부류연예 나타나는 여러성분에 대한 현재까지의 연구결과를 문헌을 토대로 요약정리하여 본다. 부류연에 나타나는 연기성분의 함량을 주류연과 비교하고 부류연을 포집하기 위해 현재까지 사용된 실험설비와 environmental tobacco smoke(ETS)의 구성에 관한 부류연 자료의 중요성을 논의한다. 부류연에 대한 연구 및 주류연과 부류연의 양과 분포에 대한 연구는 연기발생 및 담배흡연시 일어나는 기작에 대한 지식을 얻는데 유용한 자료를 제공한다. 그러나 이 자료와 계산되어진 비율은 ETS의 양적구성을 밝히는데는 전혀 연관성이 없다.

  • 흡연 당사자의 직접흡연이 이와 관련한 발병률과 사망률의 주요 원인이 되어 왔다는 것은 여러 연구조사자료에 보고되어 왔다. 그러나 최근 들어 담배연기에 대한 비흡연자의 비자의적인 노출 즉, 환경담배연기(Environmental Tobacco Smoke, 이하 ETS)로 인한 보건학적 위해성에 대한 논란이 제기되면서 간접흡연은 새로운 사회문제로 대두되고 있다(Surgeon General, 1986). 1986년에 미국 National Research Council은 미국 내에서 연간 3000명에 달하는 폐암의 발생이 ETS에 대한 노출에서 기인한다고 발표한 바 있으며(NRC, 1986), 이를 근거로 1990년대 초에 미국 EPA와 NIOSH에서는 세계최초로 ETS를 인체발암성물질로 규정한 바 있다(NIOSH, 1991; USEPA, 1992).

  • 본 연구는 흡연기작을 모사한 시료채취장비를 이용하여 환경담배연기를 주류연기와 비주류연기로 구분하여 채취하고, 환경담배연기 중의 미량원소성분을 중성자방사화분석을 이용하여 분석하였다. 또한, 실내공기 중 PM2.5를 집중적으로 채취하고 인체 영향이 큰 As, Cr, Mn, Se, V, Zn를 비롯한 약 20종의 미량원소를 분석하여 그 화학적 특성을 파악하며 환경담배연기가 실내공기질에 미치는 영향을 평가하고자 하였다. 담배개피 당 미량원소 발생량은 Cl, K, Na 등을 제외한 대부분의 원소에서 비주류연기에서 더 높게 나타났고, K, Cl, Na, Al의 발생량은 개피 당 $1{\mu}g$ 이상으로 가장 많았고, Br, Fe, Zn도 높은 배출량을 보여 외부오염원과 독립적으로 실내 환경에서의 Br, Cl, Fe, K, Zn의 농도 증가에 환경담배연기가 기여하는 것으로 판단된다. PM2.5의 농도는 흡연 사무실은 $58.7{\pm}18.1{\mu}g/m^3$인 반면, 비흡연 사무실은 $38.6{\pm}12.7{\mu}g/m^3$를 보여 ETS에 의해 흡연 사무실에서 1.5배 정도 높게 나타났고, 미량원소의 농도비는 Cu (1.0)를 제외한 모든 원소에서 농도비의 평균값이 1.1~6.0으로 흡연 사무실의 원소 농도가 비흡연 사무실의 원소 농도보다 높게 나타났다. 이러한 결과는 환경담배연기가 실내 공기 중 PM2.5와 미량원소의 농도 증가의 한 원인인 것을 보여주고 있다.
