摘要
目的 了解山东省青岛市5类公共场所和工作场所室内烟草烟雾PM2．5浓度，为青岛市控烟立法提供基线数据。方法2012年6月—9月，随机选取餐馆、宾馆、政府机关、医院和学校室内共40家80个监测点、室外40个监测点，检测室内外空气PM2．5浓度并进行分析。结果青岛市各类场所室内PM2．5均值为70．0斗g／m。（9．1—228．0μg／m2）。学校PM2．5浓度（51．2μg／m3）最低，餐馆PM2．5最高（97．3μg／m2）；餐馆和宾馆室内logPM2．5分别为（1．93±0．60）和（1．86±0．51）μg／m2，均高于室外（P〈0．05）；医院、学校和政府机关室内外PM2．5差异无统计学意义（P〉0．05）。餐馆和宾馆室内PM2．5均高于其他场所（P〈0．05）；学校与医院室内PM2．5比较有明显差异（P〈0．05）。结论餐馆和宾馆室内环境烟草烟雾污染较严重，创建无烟学校和无烟医院取得一定成果。
Objective To measure levels of particulate matter less than 2. 5 microm in aerodynamic diameter （PM 2. 5 ）in different public places and workplaces and to provide baseline data for tobacco control legislation in Qingdao city. Methods Totally 80 monitoring points were established in 40 restaurants, hotels, government agencies, hospitals, and schools randomly selected in Qingdao city and indoor and outdoor PM2. 5 concentrations at the monitoring points were detected and analyzed from June to September 2012. Results The average indoor PM 2. 5 concentration for all the monitoring points was 70.0μg/m3 （9. 1 μg/m3 - 228.0 μg/m3 ） , with the lowest mean concentration of 51.2 μg/m3 for the schools and the highest of 97.3 μg/m3 for the restaurants. The logarithmic values（ 1.93±0. 60 ixg/m3 and 1.86 ± 0. 51 μg/m3 ） of indoor PM2. 5 concentration were significantly higher than those of the outdoor for restaurants and hotels （ both P 〈 0. 05 ）, while there were no significant differences observed in the values between indoor and outdoor measurements for government agencies, hospitals, and schools （ all P 〈 0.05 ）. Conclusion The indoor PM 2. 5 concentrations are higher for restaurants and hotels but relatively lower in schools and hospitals in Qingdao city, suggesting probable heavy tobacco smoke pollution in some public places and successful implementation of smoking-free policy in hospitals and schools in the city.
