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
INTRODUCTION Despite international efforts to implement smoking bans, several national legislations still allow smoking and recommend mechanical systems, such as ventilation and air extraction, to eliminate secondhand smoke (SHS) health-related risks. We aimed to quantify the relative contribution of mechanical systems and smoking bans to SHS elimination. METHODS A cross-sectional study was conducted in randomly selected establishments from 4 Mexican cities (3 with no ban). SHS exposure was assessed using nicotine passive monitors. Establishment characteristics, presence of mechanical systems, and enforcement of smoking policies were obtained through direct observation and self-report. Multilevel models were used to assess relative contributions to SHS reduction. RESULTS Compared with Mexico City, nicotine concentrations were 3.8 times higher in Colima, 5.4 in Cuernavaca, and 6.4 in Toluca. Mechanical systems were not associated with reduced nicotine concentrations. Concentration differences between cities were largely explained by the presence of smoking bans (69.1% difference reduction) but not by mechanical systems (-5.7% difference reduction). CONCLUSIONS Smoking bans represent the only effective approach to reduce SHS. Tobacco control regulations should stop considering mechanical systems as advisable means for SHS reduction and opt for complete smoking bans in public places.

Abstract
BACKGROUND Environmental Tobacco Smoke (ETS) was classified as human carcinogen (K1) by the German Research Council in 1998. According to epidemiological studies, the relative risk especially for lung cancer might be twice as high in persons who have never smoked but who are in the highest exposure category, for example hospitality workers. In order to implement these results in the German regulations on occupational illnesses, a valid method is needed to retrospectively assess the cumulative ETS exposure in the hospitality environment. METHODS A literature-based review was carried out to locate a method that can be used for the German hospitality sector. Studies assessing ETS exposure using biological markers (for example urinary cotinine, DNA adducts) or questionnaires were excluded. Biological markers are not considered relevant as they assess exposure only over the last hours, weeks or months. Self-reported exposure based on questionnaires also does not seem adequate for medico-legal purposes. Therefore, retrospective exposure assessment should be based on mathematical models to approximate past exposure. RESULTS For this purpose a validated model developed by Repace and Lowrey was considered appropriate. It offers the possibility of retrospectively assessing exposure with existing parameters (such as environmental dimensions, average number of smokers, ventilation characteristics and duration of exposure). The relative risk of lung cancer can then be estimated based on the individual cumulative exposure of the worker. CONCLUSION In conclusion, having adapted it to the German hospitality sector, an existing mathematical model appears to be capable of approximating the cumulative exposure. However, the level of uncertainty of these approximations has to be taken into account, especially for diseases with a long latency period such as lung cancer.

Abstract
UNLABELLED This study investigated the contribution of sources and establishment characteristics, on the exposure to fine particulate matter (PM(2.5)) in the non-smoking sections of bars, cafes, and restaurants in central Zurich. PM(2.5)-exposure was determined with a nephelometer. A random sample of hospitality establishments was investigated on all weekdays, from morning until midnight. Each visit lasted 30 min. Numbers of smokers and other sources, such as candles and cooking processes, were recorded, as were seats, open windows, and open doors. Ambient air pollution data were obtained from public authorities. Data were analysed using robust MM regression. Over 14 warm, sunny days, 102 establishments were measured. Average establishment PM(2.5) concentrations were 64.7 microg/m(3) (s.d. = 73.2 microg/m(3), 30-min maximum 452.2 microg/m(3)). PM(2.5) was significantly associated with the number of smokers, percentage of seats occupied by smokers, and outdoor PM. Each smoker increased PM(2.5) on average by 15 microg/m(3). No associations were found with other sources, open doors or open windows. Bars had more smoking guests and showed significantly higher concentrations than restaurants and cafes. Smokers were the most important PM(2.5)-source in hospitality establishments, while outdoor PM defined the baseline. Concentrations are expected to be even higher during colder, unpleasant times of the year. PRACTICAL IMPLICATIONS Smokers and ambient air pollution are the most important sources of fine airborne particulate matter (PM(2.5)) in the non-smoking sections of bars, restaurants, and cafes. Other sources do not significantly contribute to PM(2.5)-levels, while opening doors and windows is not an efficient means of removing pollutants. First, this demonstrates the impact that even a few smokers can have in affecting particle levels. Second, it implies that creating non-smoking sections, and using natural ventilation, is not sufficient to bring PM(2.5) to levels that imply no harm for employees and non-smoking clients.

Abstract
Neste artigo analisa-se a tendência temporal da prevalência do tabagismo no Brasil, bem como as assimetrias da prevalência de acordo com as regiões do país, a idade, o gênero e o nível socioeconômico da população. Desde o estabelecimento da relação entre tabagismo e câncer de pulmão há 60 anos, o número de tumores malignos com evidências de associação causal com o tabagismo ascendeu a vinte. O declínio da prevalência do tabagismo na população brasileira tem sido constante desde o final da década de 80. Até 2003, foi mais intenso entre os homens. A partir daquele ano, a queda tornou-se mais pronunciada entre as mulheres. As mais altas prevalências de tabagismo encontram-se no Sudeste e Sul, as duas regiões com maiores incidências de neoplasias estritamente relacionadas ao tabaco (cavidade oral, esôfago e pulmão). A exposição ambiental à fumaça do tabaco também foi examinada considerando-se os efeitos para os adultos não fumantes, que apresentam maior risco de tumores de pulmão, laringe e faringe, e entre crianças de pais fumantes, suscetíveis ao risco de hepatoblastoma e leucemia linfocítica aguda. Apesar do incontestável sucesso da política de controle do tabagismo no país, as ações de prevenção devem considerar que as parcelas da população com piores condições socioeconômicas e com baixo nível educacional são as que apresentam taxas mais altas de prevalência de tabagismo. Dentro destes segmentos populacionais os adolescentes representam uma prioridade.

Abstract
BACKGROUND Smoking bans have been implemented in a variety of settings, as well as being part of policy in many jurisdictions to protect the public and employees from the harmful effects of secondhand smoke (SHS). They also offer the potential to influence social norms and smoking behaviour of those populations they affect. OBJECTIVES To assess the extent to which legislation-based smoking bans or restrictions reduce exposure to SHS, help people who smoke to reduce tobacco consumption or lower smoking prevalence and affect the health of those in areas which have a ban or restriction in place. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL, Conference Paper Index, and reference lists and bibliographies of included studies. We also checked websites of various organisations. Date of most recent search; July 1st 2009. SELECTION CRITERIA We considered studies that reported legislative smoking bans and restrictions affecting populations. The minimum standard was having a ban explicitly in the study and a minimum of six months follow-up for measures of smoking behaviour. We included randomized controlled trials, quasi-experimental studies (i.e. non-randomized controlled studies), controlled before and after studies, interrupted-time series as defined by the Cochrane Effective Practice and Organization of Care Group, and uncontrolled pre- and post-ban data. DATA COLLECTION AND ANALYSIS Characteristics and content of the interventions, participants, outcomes and methods of the included studies were extracted by one author and checked by a second. Because of heterogeneity in the design and content of the studies, we did not attempt a meta-analysis. We evaluated the studies using qualitative narrative synthesis. MAIN RESULTS There were 50 studies included in this review. Thirty-one studies reported exposure to secondhand smoke (SHS) with 19 studies measuring it using biomarkers. There was consistent evidence that smoking bans reduced exposure to SHS in workplaces, restaurants, pubs and in public places. There was a greater reduction in exposure to SHS in hospitality workers compared to the general population. We failed to detect any difference in self-reported exposure to SHS in cars. There was no change in either the prevalence or duration of reported exposure to SHS in the home as a result of implementing legislative bans. Twenty-three studies reported measures of active smoking, often as a co-variable rather than an end-point in itself, with no consistent evidence of a reduction in smoking prevalence attributable to the ban. Total tobacco consumption was reduced in studies where prevalence declined. Twenty-five studies reported health indicators as an outcome. Self-reported respiratory and sensory symptoms were measured in 12 studies, with lung function measured in five of them. There was consistent evidence of a reduction in hospital admissions for cardiac events as well as an improvement in some health indicators after the ban. AUTHORS' CONCLUSIONS Introduction of a legislative smoking ban does lead to a reduction in exposure to passive smoking. Hospitality workers experienced a greater reduction in exposure to SHS after implementing the ban compared to the general population. There is limited evidence about the impact on active smoking but the trend is downwards. There is some evidence of an improvement in health outcomes. The strongest evidence is the reduction seen in admissions for acute coronary syndrome. There is an increase in support for and compliance with smoking bans after the legislation.

Abstract
INTRODUCTION In Taiwan, the Smoke-Free Restaurant Program (SFRP) was implemented from 2003 to 2005 as an initial phase before the introduction of restrictive legislation promoting smoke-free restaurants (SFRs). No studies have evaluated trends in public opinion before and after a national health promotion campaign for the introduction of SFRs on a voluntary basis. The present study investigated whether public opinion with respect to eliminating environmental tobacco smoke (ETS) in restaurants changed after implementation of the SFRP. METHODS Data were obtained from four large-scale, nationally representative surveys conducted in 2003-2005 before and after implementation of the SFRP. Weighted analyses were performed to obtain nationally representative results. RESULTS After a series of SFRP campaigns, reported exposure to ETS in restaurants by survey participants decreased by approximately 14%. Approximately 20% more people had heard of SFRs, and approximately 25% more had chosen to dine in a smoke-free restaurant. We found consistently high community support for SFRs (ca. 95%), and approximately 80% supported smoke-free restaurant legislation, although both rates dropped slightly in 2005. People aged 60 years or more, nonsmokers, and those who had greater knowledge of ETS hazards were more likely to support smoke-free restaurant legislation. DISCUSSION The SFRP was effective at promoting SFRs on a voluntary basis. Strong community endorsement has major implications for legislators who are considering the nature and extent of further smoke-free restaurant legislation in Taiwan and other countries.

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
OBJECTIVE To determine whether measurement of cotinine in saliva is a sensitive measure of exposure to second-hand smoke (SHS) among customers in bars. DESIGN Before/after comparison of saliva cotinine and subjective assessments of SHS. SETTING Three bars in Wellington, New Zealand, June 2003. PARTICIPANTS Eleven non-smoking medical students spent three hours in each location. They provided saliva samples before and after the visit, counted numbers of lit cigarettes in each bar, and assessed the smokiness of the venue. Samples were tested for cotinine using liquid chromatography coupled with mass spectrometry. RESULTS Cotinine levels post-visit were consistently higher than baseline. The mean difference was 1.03 ng/mL with a 95% confidence interval of 0.76-1.30 ng/ mL. Adjustments to post-visit levels for metabolism and clearance of cotinine made very little difference to these results. Males tended to have higher baseline levels than females, and to show smaller increases. The bar with the greatest increase in cotinine was judged to be the smokiest on the basis of averaged cigarette counts and scores for presence of smoke and odour. CONCLUSION The cotinine in saliva, when tested with the analytic methods described here, provides a means of assessing relatively short-term exposures to SHS.

Abstract
This study assessed differences in the indoor air quality and occupancy levels in seventeen bars due to a city-wide smoking ban that took effect on September 1, 2005 in Austin, Texas, USA. We measured the following in each venue before and after the smoking ban: mean number of occupants, mean number of lit cigarettes, temperature, relative humidity, room volume, and PM(2.5), CO, and CO(2) concentrations. Additionally, VOC measurements were conducted at three of the venues. There was not a statistically significant change in occupancy, but the best estimate PM(2.5) concentrations in the venues decreased 71-99%, a significant reduction in all venues, relative to the pre-ban levels; CO concentrations decreased significantly in all but one venue; and concentrations of VOCs known to be emitted from cigarettes decreased to below the detection limit for all but two common compounds. These results suggest that the smoking ban has effectively improved indoor air quality in Austin bars without an associated decrease in occupancy.

Abstract
Exposure of nonsmokers to environmental tobacco smoke results in increased risk for cancer and other diseases. In spite of this finding, some restaurants and bars continue to permit smoking. This study examined the uptake of nicotine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), a potent lung carcinogen, in nonsmokers who work in restaurants and bars that permitted smoking. Urine samples were collected for 24 hours on working and nonworking days and were analysed for total NNAL [the sum of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and its glucuronides (NNAL-Glucs)], metabolites of NNK. In addition, urine samples were analysed for total nicotine (nicotine plus nicotine glucuronide), and total cotinine (cotinine plus cotinine-N-glucuronide). The results showed significant increases in urinary levels of total NNAL, total nicotine, and total cotinine on working days compared with nonworking days. The results of this study show that smoke exposure in bars and restaurants may have important health effects on nonsmoking employees, elicited by the increase in carcinogen levels.

Abstract
Clean indoor air (CIA) ordinances in Toledo, Ohio, and Bowling Green, Ohio, regulate smoking in restaurants to protect patrons and employees. Yet complete protection is questionable because the ordinances allow for smoking in certain dining sections. Two restaurants were studied in each city, one smoking and one nonsmoking. Levels of contaminants related to environmental tobacco smoke (ETS)--determined by personal and area air monitoring-in the nonsmoking restaurants were comparable to levels in a control environment. However, levels of ETS-related contaminants in the smoking restaurants, including designated nonsmoking sections, were significantly higher than levels in the control environment. ETS-related contamination of the nonsmoking sections in the smoking restaurants is attributable to direct openings between the smoking and nonsmoking sections. Reasonable protection of employees and patrons against ETS-related contaminants requires strict enforcement of CIA ordinances. Full protection is achievable only with 100% smoke-free policies.

Abstract
The authors sought to determine levels of urinary cotinine and its association with collateral exposure to second-hand smoke in public health workers. Urinary cotinine was measured twice at 1-wk intervals in 28 public health workers or their spouses. Information on sources of second-hand smoke exposure and a dietary history were obtained from each participant. Geometric mean and median cotinine levels were 2.74 and 2.33 ng/mL, respectively. Only 6 instances of second-hand smoke exposure were reported from a combined 204 days of potential exposure, and these did not correspond to higher cotinine values. There was no association between consumption of foods containing nicotine and log-transformed urine cotinine levels (p = .80). The authors' analysis indicates dietary sources of nicotine are not important, even for persons with very low urinary cotinine levels. Further study is needed to determine sources of variation in urinary cotinine among largely unexposed populations.
