Indoor air quality in a public building following smoking bans

Introduction: Exposure to environmental tobacco smoke (ETS) is a major environmental risk factor. Indoor contaminants come from a variety of sources, which can include inadequate ventilation, volatile organic compounds (VOCs), biological agents, combustion products, and ETS. Because ETS is one of the most frequent causes of IAQ complaints as well as the high mortality of passive smoking, in June 2004 the University of Geneva made the decision to ban smoking inside the so called "Uni-Mail" building, the biggest Swiss University human science building of recent construction, and the ordinance was applied beginning in October 2004. This report presents the finding related to the IAQ of the "Uni-Mail" building before and after smoking bans using nicotine, suspended dust, condensate and PAHs level in air as tracers to perform an assessment of passive tobacco exposure for non-smokers inside the building. Methods: Respirable particles (RSP) A real time aerosol monitor (model DataRAM)was place at sampling post 1, level ground floor. Condensate It consists in extracting any organic matter taken on the glass fibre filters by MeOH, and then measuring the total absorbent of the MeOH extract to the UV wavelength of 447 nm. Nicotine Nicotine was taken by means of cartridges containing of XAD-4 to the fixed flow of 0.5 L/min. The analytical method used for the determination of nicotine is based on gas chromatography with Nitrogen selective detector GC-NPD. Results: Figure 1 shows the box plot density display of 3 parameters before and after smoking bans for all 7 sampling posts: dust, condensate and nicotine in air in μg/m3. Conclusion: Before the smoking ban, the level of the concentrations of respirable particles (RSP) is raised more, average of the day 320 μg/m3, with peaks of more than 1000 μg/m3, compared with the values of the surrounding air between 22 and 30 μg/m3. The nicotine level is definitely more important (average 5.53 μg/m3, field 1.5 to 17.9 μg/m3). Once the smoking bans inside the building were applied, one notes a clear improvement in terms of concentrations of pollutants. For dust, the concentration fell by 3 times (average: 130 μg/m3, range: 40 to 160 μg/m3) and that of nicotine by 10 times (average: 0.53 μg/m3, range: 0 to 1.69 μg/m3) compared to that found before smoking bans. The outdoor air RSP concentration was 22 μg/m3 or 10 times lower. Nicotine seems to be the best tracer for ETS free of interference, independent of location or season.

Advertising bans

I show that an advertising ban is more likely to increase -- ratherthan decrease -- total consumption when advertising does not bring abouta large expansion of market demand at given prices and when it increasesproduct differentiation (thus allowing firms to command higher prices). Inthis case, the main impact of a ban on advertising is to reduce equilibriumprices and thus increase demand. I argue that this is more likely tohappen in mature industries where consumer goods are ex--ante (i.e.without advertising) similar and advertising is of the `persuasive' type.The ban is the more likely to increase profits of the firms the weakerthe ability of advertising to expand total demand and the less advertisingserves to induce product differentiation.

The effect of workplace smoking bans on heart rate variability and pulse wave velocity of non-smoking hospitality workers

OBJECTIVES: To investigate the effect of a change in second-hand smoke (SHS) exposure on heart rate variability (HRV) and pulse wave velocity (PWV), this study utilized a quasi-experimental setting when a smoking ban was introduced. METHODS: HRV, a quantitative marker of autonomic activity of the nervous system, and PWV, a marker of arterial stiffness, were measured in 55 non-smoking hospitality workers before and 3-12 months after a smoking ban and compared to a control group that did not experience an exposure change. SHS exposure was determined with a nicotine-specific badge and expressed as inhaled cigarette equivalents per day (CE/d). RESULTS: PWV and HRV parameters significantly changed in a dose-dependent manner in the intervention group as compared to the control group. A one CE/d decrease was associated with a 2.3 % (95 % CI 0.2-4.4; p = 0.031) higher root mean square of successive differences (RMSSD), a 5.7 % (95 % CI 0.9-10.2; p = 0.02) higher high-frequency component and a 0.72 % (95 % CI 0.40-1.05; p < 0.001) lower PWV. CONCLUSIONS: PWV and HRV significantly improved after introducing smoke-free workplaces indicating a decreased cardiovascular risk.

Litigation against fracking bans and moratoriums in the US: exit, voice and loyalty

A number of US states, counties and municipalities have responded to the public health and environmental concerns surrounding fracking by imposing bans or moratoriums on unconventional oil and gas drilling. These restrictions have, in recent years, given rise to litigation challenges by oil and gas companies and by property owners deprived of potential revenues. The current article begins by examining precisely who has litigated. Have large companies dominated or is it mostly smaller independents? Is there a difference in litigation rates between private and public companies? The article then considers how Hirschman’s ideas of exit, voice and loyalty might apply in the context of bans and moratoriums and further explores some of the factors that may have driven litigation in the area.

Regulation as country-specific (dis-)advantage:smoking bans and the location of foreign direct investment in the tobacco industry

This paper seeks to examine the relationship between smoking bans and the propensity of tobacco firms to engage in foreign direct investment (FDI). Using international business theory based on the firm-specific advantage/country-specific advantage (FSA/CSA) matrix, the authors show that, contrary to what one may expect, smoking bans at home are an important institutional intervention, reducing the propensity for firms to engage in FDI, even to countries without a ban themselves.

Strategic Approach to Smoking Bans: Delaware Gaming Industry

A study of Delaware’s statewide smoking ban suggests that it may have had a significant negative economic impact on the state’s gaming industry. However, such impact may vary in different segments of the hospitality industry, and therefore, must be examined strategically and on a case-by-case basis. The specific market environment, including both demand and competition of each state or each municipality, should be carefully analyzed by both governmental decision makers and by hospitality operators who influence these decision makers.

Smoking Restrictions, Bans Rise in Hospitality Industry

With the rise of smoking restrictions and bans in the hospitality industry the author discusses solutions that are implemented to protect the workforce and guests from involuntary smoking. Historical and societal contexts are drawn, and enforcement of smoking bans as well as their economic impact is explored in an international perspective, primarily since US researchers have propelled the research on smoking and health issues. The author illustrates that there has been no way to avoid enforcements of strict smoking restrictions, and the struggle to do so could just delay the process and waste resources.
