摘　　要：目的:通过对室内PM2.5浓度进行监测,比较河南省不同医疗卫生机构室内烟草烟雾污染情况。方法:在河南省东、西、南、北、中5个区域分别选择1个市,将其卫生局、疾病预防控制中心(简称疾控中心)、医院、妇幼保健院共38家医疗卫生机构作为监测对象,采用气溶胶监测仪对室内、外PM2.5浓度进行监测,并记录室内监测场所的容积、场内人数、正在吸烟人数。结果:4类医疗卫生机构室内PM2.5平均浓度为(87.4±15.1)μg/m3,卫生局、疾控中心、医院、妇幼保健院分别为(71.8±15.5)、(71.3±14.3)、(103.8±16.9)、(51.4±11.3)μg/m3。室外PM2.5平均浓度为(68.9±12.5)μg/m3,室、内外比较差异有统计学意义(t=6.585,P<0.001),室内比室外高27.9%。医院、妇幼保健院室内PM2.5浓度均高于室外(t=6.659、5.383,P均<0.05)。室内PM2.5浓度与室内吸烟者密度、室外PM2.5浓度均呈正相关(r s=0.524、0.426,P均<0.001)。结论:在无烟医疗卫生系统的创建和管理上,应把医院及妇幼保健院作为控烟重点。Aim：To evaluate indoor tobacco smoke pollution in medical and health institutions of Henan province by monitoring the concentration of PM2. 5. Methods：A total of 38 health bureaus,centers for disease control and prevention（ CDCs）,hospitals,women and children＇s hospitals,from five cities in different parts of Henan province were randomly selected as monitoring sites. Aerosol monitor was used to monitor the concentration of PM2. 5 indoors and outdoors of each selected site. Meanwhile,the size of monitored sites,the number of people and the number of smokers were recorded for further evaluation. Results：The average concentration of indoors PM2. 5 of the four types of medical and health institutions was（ 87. 4 ± 15. 1） μg / m3,while the average concentration of outdoors was（ 68. 9 ± 12. 5） μg/m3（ t = 6. 585,P 0. 001）. The highest concentration of indoors was 27. 9% higher than that of outdoors. The average PM2. 5 concentrations indoors in health bureaus,CDCs,hospitals,and women and children＇s hospitals were（ 71. 8 ± 15. 5）,（ 71. 3 ± 14. 3）,（ 103. 8 ±16. 9）,and（ 51. 4 ±11. 3） μg/m3,respectively. The PM2. 5 concentrations indoors of hospitals and women and children＇s hospitals were higher than outdoors（ t = 6. 659,5. 383,P 0. 05）. The PM2. 5 concentration indoors was positively correlated with the density of the smokers as well as the PM2. 5 concentration outdoors（ r s= 0. 524,0. 426,P 0. 001）. Conclusion：The hospitals and women and children＇s hospitals should be focused on in the process of creation and management of non-smoking medical and health institutions.
