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 understand the indoor air PM2.5 concentration in Shenzhen hospital. Methods Five hospitals in Shenzhen were selected for PM2.5 concentration monitoring. Outpatient hall, ward corridor, male restroom, doctor’s office and nurse’s office were selected in each hospital. Five monitoring points were selected according to the plum blossom points in each area and monitored during outpatient clinic time. Results The concentration of PM2.5 in male restroom was the highest (53.35μg / m3), followed by the physician’s office (45.80μg / m3) and the lowest concentration was in nurse’s office (19.67μg / m3) (P <0.05). The concentrations of PM2.5 in outpatient lobby, male restroom and doctor’s office were significantly higher than those in nurses office (P <0.05). Conclusion The polluted PM2.5 in men’s restroom and doctor’s office in this investigation is more serious, which may be related to smoking. Tobacco control should be strengthened to control PM2.5 pollution.
