摘　　要：目的了解深圳市医院室内空气PM2.5浓度。方法选取深圳市5所医院进行PM2.5浓度监测。每所医院选取门诊大厅、病房楼道、男洗手间、医生办公室、护士办公室5个监测区域,每个区域按照梅花布点选取5个监测点,于门诊时间进行监测。结果男洗手间PM2.5的浓度最高(53.35μg/m3),其次是医生办公室(45.80μg/m3),浓度最低的为护士办公室(19.67μg/m3);不同功能区PM2.5浓度差异有统计学意义(P<0.05),门诊大厅、男洗手间和医生办公室PM2.5浓度均显著高于护士办公室(P<0.05)。结论本次调查的医院男洗手间和医生办公室空气PM2.5污染较为严重,可能与吸烟有关,应加强控烟,控制PM2.5污染。Objective To know indoor air PM2.5 concentration in hospitals in Shenzhen, Guangdong.
