Second-hand smoke contains several toxic chemicals that are known to pollute the air and harm people's health. In India, smoking in public places has been prohibited since October 2008 as a way to reduce second-hand smoke (SHS) exposure. The purpose of the present study was to assess the implementation of smoke-free policies and its impact on indoor air quality by measuring the PM(2.5) levels in bars and restaurants, restaurants, country liquor bars, hookah restaurants and pubs in Mumbai.
Air quality measurements at 50 venues were conducted by using a "SIDEPAK(™) AM510 Personal Aerosol Monitor" during April to May 2009. Average concentration of PM(2.5) (μg/m(3)) particles was calculated separately for each venue.
Smoking was observed in 36% of the surveyed venues during an hour of data collection. The PM(2.5) levels ranged from 16.97 to 1101.76 μg/m(3). The average level of PM(2.5) among non-smoking venues was 97.19 μg/m(3) and among smoking venues was 363.04 μg/m(3).
Considerable scope for improvement in implementation of smoke-free policies exists. The PM(2.5) levels were exceedingly high in venues where smoking was observed.
二手烟含有多种有毒化学物质,已知会污染空气并危害人们的健康。在印度,自2008年10月起禁止在公共场所吸烟,以此减少二手烟暴露。本研究的目的是通过测量孟买的酒吧、餐厅、乡村酒馆、水烟馆和酒吧内的PM(2.5)水平,评估无烟政策的实施情况及其对室内空气质量的影响。
2009年4月至5月期间,使用“SIDEPAK(™) AM510个人气溶胶监测仪”在50个场所进行空气质量测量。分别计算每个场所PM(2.5)(μg/m³)颗粒的平均浓度。
在一小时的数据收集期间,36%的被调查场所存在吸烟现象。PM(2.5)水平在16.97至1101.76μg/m³之间。无烟场所的PM(2.5)平均水平为97.19μg/m³,吸烟场所为363.04μg/m³。
无烟政策的实施仍有很大的改进空间。在观察到有吸烟现象场所的PM(2.5)水平极高。
