背景暴露于烟草水烟斗的排放物与其使用者以及暴露于其二手烟的人的健康风险增加有关。烟斗的使用是烟草控制界特别是东地中海地区国家新出现的一个关切问题。2002年，卡塔尔通过了一项立法，禁止在公共场所吸烟，但免除了吸烟。为了制定和执行有效的政策，监测了卡塔尔多哈水烟斗咖啡馆使用香烟和水烟对室内空气质量的影响。方法于2012年7月至10月在卡塔尔多哈的40个水烟斗咖啡馆和16个无烟场所抽样测量了室内和室外颗粒物(PM2.5)水平。此外，每个场地内被吸烟的水烟斗数量和吸烟人数也被计算在内。采用非配对样本t检验和配对样本t检验，比较不同场馆类型(水管型与无烟型)与环境(室内与室外)PM2.5平均值的差异。结果水管型场馆PM2.5平均值(476µg/m(3))显著高于无烟场馆内PM2.5平均值(17µg/m(3)；P<0.05)。
Background Exposure to the emissions of a tobacco waterpipe is associated with increased health risks among its users as well as those exposed to its secondhand smoke. Waterpipe use is an emerging concern to the tobacco control community, particularly among countries of the Eastern Mediterranean Region. In 2002, Qatar adopted legislation that prohibited cigarette smoking inside public venues, but exempted tobacco waterpipe smoking. To inform the development and enforcement of effective policy, the impact of cigarette and waterpipe use on indoor air quality was monitored in waterpipe cafes in Doha, Qatar.Methods Particulate matter (PM2.5) levels were measured inside and outside of a sample of 40 waterpipe cafes and 16 smoke-free venues in Doha, Qatar between July and October 2012. In addition, the number of waterpipes being smoked and the number of cigarette smokers were counted within each venue. Non-paired and paired sample t tests were used to assess differences in mean PM2.5 measurements between venue type (waterpipe vs smoke-free) and environment (indoor vs outdoor).Results The mean PM2.5 level inside waterpipe venues (476 mu g/m(3)) was significantly higher than the mean PM2.5 level inside smoke-free venues (17 mu g/m(3); p
