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。
Objective To understand the exposure of secondhand smoke in key indoor places in Tianjin and provide data support for the implementation of the “Tianjin Tobacco Control Regulations”. Methods The indoor air PM2.5 monitoring was conducted in 44 sites in 5 categories (medical and health institutions, government offices, public transportation waiting places, food and beverage outlets and bars) in 7 districts of Tianjin from December 2012 to February 2013, Air nicotine concentrations were monitored in 10 of these locations. Results The median of PM2.5 concentrations in dining establishments was highest at 156.0 μg / m3 in different types of places monitored, followed by bars. However, exposure to second-hand smoke in male toilets in other places was more severe with a health care institution of 129.5 μg / m3, the government office was 102.0 μg / m3 and the public transport waiting area was 116.0 μg / m3. The concentration of PM2.5 was positively correlated with the amount of the burning cigarettes in the premises (rs = 0.281, P <0.05) And PM2.5 concentration was positively correlated (rs = 0.553, P <0.05). Conclusion The second-hand indoor smoke exposure in key places in Tianjin in this survey is still at a high level. More targeted measures are needed to reduce exposure to secondhand smoke and protect the public from harm.
