背景：环境烟草烟雾(ETS)会导致非吸烟者患病。工作场所禁烟是减少接触ETS的干预措施，试图防止有害的健康影响。2004年3月29日，爱尔兰政府出台了第一项全国性全面立法，禁止在所有工作场所吸烟，包括酒吧和餐馆。这项研究考察了这项立法对酒吧空气质量和都柏林酒吧工作人员呼吸健康影响的影响。对42家酒吧在禁令实施前后的颗粒物浓度(PM2.5)和颗粒物浓度(PM10)进行了测量和比较。其中26家酒吧的苯浓度也进行了测量。健康效应研究。81名巴曼自愿接受了全面的肺功能研究，呼气一氧化碳和唾液可替宁水平在禁令实施前和禁令实施一年后重复进行。他们还完成了关于暴露于ETS和两种情况下呼吸道症状的问卷调查。PM2.5降低了83%，酒吧中的苯浓度降低了80.2%。健康效应研究。呼出的一氧化碳减少了79%，唾液可替宁减少了81%。禁烟后，不吸烟的酒吧志愿者在测量的肺功能测试中有显著的改善，自我报告的症状和暴露水平显著减少。结论：工作场所全面禁烟显著减少了酒吧的空气污染，改善了酒吧的呼吸健康。
Background: Environmental tobacco smoke (ETS) causes disease in nonsmokers. Workplace bans on smoking are interventions to reduce exposure to ETS to try to prevent harmful health effects. On March 29, 2004, the Irish government introduced the first national comprehensive legislation banning smoking in all workplaces, including bars and restaurants. This study examines the impact of this legislation on air quality in pubs and on respiratory health effects in bar workers in Dublin.Methods: EXPOSURE STUDY. Concentrations of particulate matter 2.5 mu m or smaller (PM2.5) and particulate matter 10 lam or smaller (PM10) in 42 pubs were measured and compared before and after the ban. Benzene concentrations were also measured in 26 of the pubs. HEALTH EFFECTS STUDY. Eighty-one barmen volunteered to have full pulmonary function studies, exhaled breath carbon monoxide, and salivary cotinine levels performed before the ban and repeated 1 year after the ban. They also completed questionnaires on exposure to ETS and respiratory symptoms on both occasions.Findings: EXPOSURE STUDY. There was an 83% reduction in PM2.5 and an 80.2% reduction in benzene concentration in the bars. HEALTH EFFECTS STUDY. There was a 79% reduction in exhaled breath carbon monoxide and an 81% reduction in salivary cotinine. There were statistically significant improvements in measured pulmonary function tests and significant reductions in self-reported symptoms and exposure levels in nonsmoking barmen volunteers after the ban.Conclusions: A total workplace smoking ban results in a significant reduction in air pollution in pubs and an improvement in respiratory health in barmen.
