Measurements of the environmental tobacco smoke (ETS) exposure in public places in Florence. This study was part of the first European multicenter project, intended to measure ETS exposure in public places in a number of European Cities (Florence, Barcelona, Paris, Oporto, Athens, Wien and Orebro).
Nicotine vapour phase was measured using passive samplers, composed of a sodium bisulphate treated filter held in a plastic cassette with a windscreen on one side. The filters were analysed at the Laboratory of the Public Health Agency of Barcelona, Spain, by gas-chromatography/mass spectrometry (GC/MS).
Nicotine concentration (in microg/m3) by public place, by smoking policy, and, for restaurants with separated areas, by smoking and non-smoking section.
Nicotine measurements were conducted in 5 schools, 3 university departments, 5 hospitals, 1 railway station, 1 airport, 7 bars, 7 restaurants, and 4 discotheques in Florence.
The average nicotine concentration in discotheques and restaurants were respectively 26.78 microg/m3 and 2.32 microg/m3. In the other public places the concentration was about 1 microg/m3. In smoke-free public places the average concentration was 0.85 microg/m3; in public places where smoking is allowed concentration was higher (11.53 microg/m3). In the smoking section and non-smoking section of restaurants with separated areas the average concentration was respectively 2.54 and 2.14 microg/m3.
The highest nicotine concentrations were recorded in discos and restaurants. A smoke-free public place is effective in reducing ETS exposure. Smoking and non-smoking sections in restaurants without a separate ventilation system seem not to solve ETS exposure.
测量佛罗伦萨公共场所的环境烟草烟雾（ETS）暴露情况。本研究是首个欧洲多中心项目的一部分，旨在测量多个欧洲城市（佛罗伦萨、巴塞罗那、巴黎、波尔图、雅典、维也纳和厄勒布鲁）公共场所的ETS暴露情况。
使用被动采样器测量尼古丁气相，该采样器由一个用硫酸氢钠处理过的滤器组成，放置在一个塑料盒中，一侧有挡风玻璃。滤器在西班牙巴塞罗那公共卫生机构实验室通过气相色谱/质谱法（GC/MS）进行分析。
按公共场所、吸烟政策，以及对于有分隔区域的餐厅，按吸烟区和非吸烟区划分的尼古丁浓度（微克/立方米）。
在佛罗伦萨的5所学校、3个大学院系、5家医院、1个火车站、1个机场、7家酒吧、7家餐厅和4家迪斯科舞厅进行尼古丁测量。
迪斯科舞厅和餐厅的平均尼古丁浓度分别为26.78微克/立方米和2.32微克/立方米。在其他公共场所，浓度约为1微克/立方米。在无烟公共场所，平均浓度为0.85微克/立方米；在允许吸烟的公共场所，浓度更高（11.53微克/立方米）。在有分隔区域的餐厅的吸烟区和非吸烟区，平均浓度分别为2.54微克/立方米和2.14微克/立方米。
迪斯科舞厅和餐厅的尼古丁浓度最高。无烟公共场所能有效降低ETS暴露。没有独立通风系统的餐厅的吸烟区和非吸烟区似乎无法解决ETS暴露问题。
