Abstract
UNLABELLED Field observation of patron smoking behaviors and multiple sampling approaches were conducted in 79 restaurants and bars in Beijing, 2010, 2 years after implementing the governmental smoking regulations. Smoking was observed in 30 visits to 22 of the 37 nominal non-smoking venues during peak patronage times and six visits to four of the 14 nominal non-smoking sections. The median area secondhand smoke (SHS) concentrations during peak patronage time were 27, 15, 43, and 40 μg/m(3) in nominal non-smoking venues, non-smoking sections, smoking sections, and smoking venues, respectively, as indicated by the difference between indoor and outdoor PM2.5 levels; and 1.4, 0.6, 1.7, and 2.7 μg/m(3) , respectively, as indicated by airborne nicotine. In the 27 venues with sampling of different approaches and over different time periods, the median nicotine concentration was 1.8 μg/m(3) by one-hour peak patronage-time sampling, 1.1 μg/m(3) by 1-day active area sampling, 2.5 μg/m(3) by 1-day personal sampling, and 2.3 μg/m(3) by week-long passive sampling. No significant differences in nicotine levels were observed among venues/sections with different nominal smoking policies by all sampling approaches except during peak patronage time. This study showed that the 2008 Beijing governmental smoking restriction has been poorly implemented, and SHS exposures in Beijing restaurants and bars remain high. PRACTICAL IMPLICATIONS The 2008 Beijing governmental smoking restriction requires large restaurants to designate no less than 50% of their dining area as non-smoking, without defining ‘large’ or specifying how the designated smoking sections and non-smoking sections should be separated. Two years after its implementation, smoking is still commonly observed in nominally non-smoking restaurants and bars and in designated non-smoking sections, and both patrons and servers are exposed to high concentrations of secondhand smoke. These results indicate that the Beijing governmental regulation fails to protect the population from SHS exposure in restaurants and bars and that more efforts are needed to pass stronger smoking regulations and ensure better compliance in Beijing, China.

Abstract
Fine particles in hospitality venues with insufficient smoking bans indicate health risks from passive smoking. In a random sample of Viennese inns (restaurants, cafes, bars, pubs and discotheques) effects of partial smoking bans on indoor air quality were examined by measurement of count, size and chargeable surface of ultrafine particles (UFPs) sized 10-300 nm, simultaneously with mass of particles sized 300-2500 nm (PM2.5). Air samples were taken in 134 rooms unannounced during busy hours and analyzed by a diffusion size classifier and an optical particle counter. Highest number concentrations of particles were found in smoking venues and smoking rooms (median 66,011 pt/cm(3)). Even non-smoking rooms adjacent to smoking rooms were highly contaminated (median 25,973 pt/cm(3)), compared with non-smoking venues (median 7408 pt/cm(3)). The particle number concentration was significantly correlated with the fine particle mass (P<0.001). We conclude that the existing tobacco law in Austria is ineffective to protect customers in non-smoking rooms of hospitality premises. Health protection of non-smoking guests and employees from risky UFP concentration is insufficient, even in rooms labeled "non-smoking". Partial smoking bans with separation of smoking rooms failed.

Abstract
The aim of the present study was to develop a new analytical method of chromatographic determination of two important markers of ETS exposure: nicotine and 3-vinylpyridine (3-ethenylpyridine, 3-EP) in mainstream (MS) and sidestream (SS) smoke of one single cigarette and in indoor air using direct solid phase extraction combined with gas chromatography. The method can be utilised for both nicotine and 3-EP determination in SS and MS of one single cigarette as well as it allows for a precise determination of compound distribution in indoor air. The application of the same analytical method for both kinds of samples allows anticipating indoor air distribution of both analysed compounds in a very precise way. The precision of the method (calculated as a relative standard deviation) was 9.78% for nicotine and 2.67% for 3-EP; whereas the accuracy (evaluated by a recovery study conducted at three different levels) was 70.1 and 87.3%, respectively. The limit of detection was 0.06 µg per cigarette for both nicotine and 3-EP. The method was evaluated by determining the compounds of interest in two commercially available brands of cigarettes as well as in the reference cigarettes 3R4F and also in indoor air polluted with tobacco smoke. Determined levels of compounds of interest in MS varied from 586 to 772 (nicotine) µg per cigarette and from 3.5 to 10.7 (3-EP) µg per cigarette. In SS smoke the level varied from 14,370 to 22,590 (nicotine) µg per cigarette and from 185 to 550 (3-EP) µg per cigarette, whereas levels in indoor air polluted with tobacco smoke varied from 50.1 to 157.3 (nicotine) µg m(-3) and from 7.7 to 20.8 (3-EP) µg m(-3).

Abstract
UNLABELLED The aim of this paper was to compare nicotine concentration in 28 hospitality premises (HPs) in Florence and Belluno, Italy, where a smoking ban was introduced in 2005, and in 19 HPs in Vienna, Austria, where no anti-smoking law entered into force up to now. Airborne nicotine concentrations were measured in the same HPs in winter 2002 or 2004 (pre-ban measurements) and winter 2007 (post-ban measurements). In Florence and Belluno, medians decreased significantly (P < 0.001) from 8.86 [interquartile range (IQR): 2.41-45.07)] before the ban to 0.01 microg/m3 (IQR: 0.01-0.41) afterwards. In Austria (no smoking ban) the medians collected in winters 2004 and 2007 were, respectively, 11.00 (IQR: 2.53-30.38) and 15.76 microg/m3 (IQR: 2.22-31.93), with no significant differences. Measurements collected in winter 2007 in 28 HPs located in Naples, Turin, Milan (0.01 microg/m3; IQR: 0.01-0.16) confirmed post-ban results in Florence and Belluno. The medians of nicotine concentrations in Italy and Austria before the Italian ban translates, using the risk model of Repace and Lowery, into a lifetime excess lung cancer mortality risk for hospitality workers of 11.81 and 14.67 per 10,000, respectively. Lifetime excess lung cancer mortality risks for bar and disco-pub workers were 10-20 times higher than that calculated for restaurant workers, both in Italy and Austria. In winter 2007, it dropped to 0.01 per 10,000 in Italy, whereas in Austria it remained at the same levels. The drop of second-hand smoke exposure indicates a substantial improvement in air quality in Italian HPs even after 2 years from the ban. PRACTICAL IMPLICATIONS The nation-wide smoking ban introduced in Italy on January 10, 2005, resulted in a drop in second-hand smoke exposure in hospitality premises, whereas in Austria, where there is no similar nation-wide smoking ban, the exposure to second-hand smoke in hospitality premises remains high. Given that second-hand smoke is considered a group 1 carcinogen according to the International Agency for Research on Cancer classification, the World Health Organization Framework Convention on Tobacco Control strongly recommends the implementation of nation-wide smoke-free policies in order to improve the indoor air quality of hospitality premises and workplaces. Results from our study strongly supports this recommendation.

Abstract
In contrast to other countries, there is an on-going debate but still no smoke-free legislation in Germany. Exposure to environmental tobacco smoke (ETS) in hospitality venues is assumed to be high, but air quality data are lacking. Therefore, the aim of our study was to perform a comprehensive exposure assessment by analysing the indoor air concentration of toxic or carcinogenic ETS compounds in restaurants, pubs, and discotheques. Active sampling of indoor air was conducted for 4 h during the main visiting hours in 28 hospitality venues. Polycyclic aromatic hydrocarbons (PAH), volatile organic compounds (VOC), aldehydes/ketones, and cadmium were analysed. In addition, particle mass concentration was assessed with two different methods and particle number concentration (PNC) was determined. Median nicotine levels were 15 microg/m(3) in restaurants, 31 microg/m(3) in pubs, and 193 microg/m(3) in discotheques. Across these three sampling site categories median levels of 3-ethenylpyridine ranged from 3 to 24 microg/m(3), median levels of benzene from 8 to 20 microg/m(3), median levels of cadmium from 3 to 10 ng/m(3), and median levels of the sum of 16 PAH according to US-EPA from 215 to 375 ng/m(3), respectively. Median PM(2.5) mass concentration assessed gravimetrically varied between 178 and 808 microg/m(3) and PNC between 120,000 and 210,000 particles per cm(3) in restaurants, pubs, and discotheques. The majority of the particles had a size of 0.01-0.5 microm. Concentrations of ETS compounds were always highest in discotheques. The strong correlation between ETS-specific markers (nicotine, 3-ethenylpyridine) and PM(2.5), PAH, VOC, aldehydes/ketones, and cadmium indicated ETS as main source of these toxic or carcinogenic substances. In conclusion, indoor air concentrations of ETS constituents were high in German hospitality venues and represented a substantial health threat. Effective measures to protect patrons and staff from ETS exposure are necessary from a public health point of view.

Abstract
RATIONALE Both prenatal and postnatal passive smoking have been linked with respiratory symptoms and asthma in childhood. Their differential contributions to lung function growth in the general children's population are less clear. OBJECTIVE To study the relative impact of pre- and postnatal exposure on respiratory functions of primary school children in a wide range of geographic settings, we analyzed flow and volume data of more than 20,000 children (aged 6-12 yr) from nine countries in Europe and North America. METHODS Exposure information had been obtained by comparable questionnaires, and spirometry followed a protocol of the American Thoracic Society/European Respiratory Society. Linear and logistic regressions were used, controlling for individual risk factors and study area. Heterogeneity between study-specific results and mean effects were estimated using meta-analytic tools. MAIN RESULTS Smoking during pregnancy was associated with decreases in lung function parameters between -1% (FEV1) and -6% maximal expiratory flow at 25% of vital capacity left (MEF25). A 4% lower maximal midexpiratory flow (MMEF) corresponded to a 40% increase in the risk of poor lung function (MMEF < 75% of expected). Associations with current passive smoking were weaker though still measurable, with effects ranging from -0.5% (FEV1) to -2% maximal expiratory flow (MEF50). CONCLUSIONS Considering the high number of children exposed to maternal smoking in utero and the even higher number exposed to passive smoking after birth, this risk factor for reduced lung function growth remains a serious pediatric and public health issue.

Abstract
In 1984, Dr. C. Everett Koop, then Surgeon General of the US, presented an important speech on the hazards of smoking. In his speech, he stated "The ultimate goal should be a smoke-free society by the year 2000." In addition, the World Health Organization (WHO) has initiated a process to ban smoking globally; on 21 May 2003, at the 56th World Health Assembly, WHO's 192 Member States unanimously adopted the world's first public health treaty, the WHO Framework Convention on Tobacco Control. Although good progress has been made, reaching the ultimate goal is far from certainty. Therefore, it is time to re-visit this crucial public health activity and re-energize the effort to reach this goal. Since numerous reports have been written on the ban of smoking based on benefits to the smokers, the emphasis of our report is on benefits to non-smokers from their exposure to environmental tobacco smoke (ETS). We provide a concise review of the impact of ETS on health and economy. In addition, we examined the different interest groups on supporting and opposing the ban, the role of the government, private citizens and medical professionals on this activity, and certain constraints on implementing the global ban. We also provide some recommendations on how to promote the ban globally. Since cigarette smoking is an unnecessary habit that has devastating consequences around the world, banning of cigarette smoking should be a global mission. A global ban on indoor smoking in public places is an important first step in an international effort to prevent morbidity and mortality caused by tobacco smoking and ETS.
