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PM 2.5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PM 2.5浓度并进行分析。结果青岛市各类场所室内PM 2.5均值为70.0μg/m3(9.1~228.0μg/m3)。学校PM 2.5浓度(51.2μg/m3)最低,餐馆PM 2.5最高(97.3μg/m3);餐馆和宾馆室内log PM 2.5分别为(1.93±0.60)和(1.86±0.51)μg/m3,均高于室外(P<0.05);医院、学校和政府机关室内外PM 2.5差异无统计学意义(P>0.05)。餐馆和宾馆室内PM 2.5均高于其他场所(P<0.05);学校与医院室内PM 2.5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 understand the concentration of PM 2.5 in indoor tobacco smoke in five public places and workplaces in Qingdao, Shandong Province, and to provide baseline data for tobacco control legislation in Qingdao. Methods From June to September 2012, a total of 40 stations, 40 stations and 40 outdoor monitoring stations were selected from restaurants, hotels, government offices, hospitals and schools, and indoor and outdoor PM 2.5 concentrations were detected and analyzed. Results The indoor average PM 2.5 of all kinds of premises in Qingdao was 70.0μg / m3 (9.1 ~ 228.0μg / m3). The school PM 2.5 concentration (51.2 μg / m3) was the lowest, while the restaurant PM 2.5 was the highest (97.3 μg / m3). The log PM 2.5 was 1.93 ± 0.60 and 1.86 ± 0.51 μg / m3 in restaurants and hotels, Outdoor (P <0.05). There was no significant difference in indoor and outdoor PM 2.5 between hospitals, schools and government agencies (P> 0.05). PM 2.5 in restaurants and hotels was higher than that in other places (P <0.05); PM 2.5 in schools and hospitals was significantly different (P <0.05). Conclusion The indoor environment of restaurants and guesthouses is more polluted by tobacco smoke. Some achievements have been made in creating a smoke-free school and a smoke-free hospital.
