河南省医疗卫生机构室内 PM2．5浓度监测

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（rs ＝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 se-lected as monitoring sites .Aerosol monitor was used to monitor the concentration of PM 2.5 indoors and outdoors of each se-lected site.Meanwhile, the size of monitored sites, the number of people and the number of smokers were recorded for fur-ther evaluation.Results:The average concentration of indoors PM 2.5 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 posi-tively correlated with the density of the smokers as well as the PM2.5 concentration outdoors (rs =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 .
