摘　　要：对严寒地区3家大型综合医院门诊与候诊厅污染物进行现场测试,并运用统计学模型分析,结果表明:3家医院均存在CO_(2)超标现象,且高峰时段浓度值均超过1 500 ppm,CO_(2)浓度超标是医院内人员密度增加导致的;3家医院不同粒径可吸入颗粒物浓度达标率均接近100%,室外空气中的可吸入颗粒物是室内可吸入颗粒物的主要污染源,雨雪天气也会影响空气中可吸入颗粒物的整体水平,人员本身作为携带者对室内可吸入颗粒物浓度产生的影响较小;3家医院细菌浓度均未超过标准限值的50%,各区域间浓度差异不明显,可能影响细菌浓度的因素包括人员密度、雨雪天气及可吸入颗粒物等。On-site testing on clinics and waiting halls of three large general hospitals in severe cold area is conducted,and statistical models are used for analysis.The results show that CO_(2) concentrations all exceed the standard in these three hospitals and the peak concentration levels all exceed 1 500 ppm,which are caused by the increase in the density of personnels in the hospitals;the compliance rates of PM concentration of different particle sizes in these three hospitals are close to 100%,the primary pollution source of indoor inhalable particulate matter is the inhalable particulate matter from outdoor air;rain and snow also influence the total amount of inhalable particulate matter in air,while personnels as carriers have less effect on indoor inhalable particulate matter concentrations;none of the bacterial concentrations in these three hospitals exceeds 50% of the standard limit,and the concentration differences between areas are not significant,and the factors affecting the bacterial concentrations include the density of personnels,outdoor rain and snow,and inhalable particulate matter.
