摘要
目的了解天津市重点室内场所二手烟暴露情况,为促进《天津市控制吸烟条例》实施提供数据支持。方法于2012年12月—2013年2月在天津市7个区5类(医疗卫生机构、政府办公机构、公共交通等候场所、餐饮场所以及酒吧)44个场所进行了室内空气PM2.5监测,并在其中的10个场所进行了空气尼古丁浓度监测。结果餐饮场所的PM2.5浓度中位数在所监测的不同类型场所中最高,为156.0μg/m3,其次为酒吧;而其他场所的男卫生间二手烟暴露较严重,医疗卫生机构为129.5μg/m3,政府办公机构为102.0μg/m3,公共交通等候场所为116.0μg/m3;PM2.5浓度与场所内正在燃烧的香烟数量之间呈正相关(rs=0.281,P<0.05);空气尼古丁浓度与PM2.5浓度呈正相关(rs=0.553,P<0.05)。结论本次调查的天津市重点场所室内二手烟暴露仍处于较高水平,需要采取更加有针对性的措施减少二手烟暴露,保护公众免受其危害。
Objectives To know the situation of secondhand smoking exposure in main public places in Tianjin and provide the scientific data for improving the implementation of Tianjin Smoke-free Law. Methods PM2.5 was monitored for 30 min in 44 sites of 5 kinds of public places including hospitals, governments, waiting rooms for public transportation, restaurants and bars, from Dee. 2012 to Feb. 2013. Air nicotine concentrations were measured for 5-7 days in ten of them. Results PM2.5 concentration in restaurants was the highest among the five kinds of public plaees, was 156.0 μg/m3, the second was bars. The male washrooms in other places had higher PM2.5 than lobbies of them, and it was 129.5 μg/m3, 102.0 μg/m3 and 116.0 μg,/m3 in hospitals, governments and waiting rooms for public transportation respectively. Average PM2.5 concentrations were positively correlated (Spearman's correlation coefficient: 0.281, P〈0.05) with active smoking density. Air nicotine concentrations were strongly and positively correlated with PM2.5 concentrations (rs=0.553, P〈0.001). Conclusion Passive smoking is still serious in Tianjin and it is need to take more targeted measures to reduce exposure to secondhand smoke.
