OBJECTIVE
To evaluate pollution by second-hand smoke in a sample of hospitality venues before and after the implementation of smoke-free legislation.
METHODS
A cross sectional, before-after study was conducted in 2008 and 2011 after the total ban. A SidePack Aerosol monitor was used both inside and outside the hospitality venues to measure fine breathable particles (PM2.5). A total of 43 places with pre- and post-legislation measurements were included.
RESULTS
The median indoor pollution in hospitality venues was 204.2μg/m(3) in 2008 and 18.82μg/m(3) in 2011; the average outdoor PM2.5 concentration was 47.04μg/m(3) in 2008 and 18.82μg/m(3) in 2011. Pollution was higher in bars and cafeterias, followed by pubs and discos. Before the law was implemented, pollution was 4.34 times higher indoors than outdoors; in 2011 the average indoor PM2.5 concentration decreased by 90.88%.
CONCLUSIONS
Only a complete ban is able to protect workers and customers against the health risks of second-hand smoke exposure.
目的
评估无烟立法实施前后酒店场所样本中的二手烟污染情况。
方法
在全面禁烟后的2008年和2011年进行了一项前后对照的横断面研究。在酒店场所内外使用SidePack气溶胶监测仪测量可吸入细颗粒物（PM2.5）。总共纳入了43个有立法前后测量数据的场所。
结果
2008年酒店场所室内污染中位数为204.2μg/m³，2011年为18.82μg/m³；2008年室外PM2.5平均浓度为47.04μg/m³，2011年为18.82μg/m³。酒吧和自助餐厅的污染更高，其次是酒馆和迪斯科舞厅。在法律实施前，室内污染比室外高4.34倍；2011年室内PM2.5平均浓度下降了90.88%。
结论
只有全面禁烟才能保护员工和顾客免受二手烟暴露带来的健康风险。
