深圳市医院室内空气中PM2.5污染水平监测与分析

Monitoring and analysis of indoor air PM 2.5 concentration in hospitals of Shenzhen City

目的通过监测医院室内空气中可吸入颗粒物PM 2.5浓度以了解深圳市医院控烟情况并为开展控烟干预提供基线数据。方法选取深圳市5家医院进行PM 2.5浓度监测。每家医院选取门诊大厅、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。PM 2.5浓度值进行对数转换呈正态分布后用SPSS 10.0软件进行数据统计分析。结果 5家医院室内空气中PM 2.5监测结果,男洗手间的浓度最高,为(53.35±50.60)μg/m3;其次是医生办公室,为(45.80±60.53)μg/m3;护士办公室浓度最低为(19.67±11.80)μg/m3。方差分析发现,不同位置PM 2.5浓度差异有统计学意义(P<0.05)。结论门诊大厅、男洗手间和医生办公室均显著高于护士办公室,政府政策干预是控烟成功的保障。医院控烟的重点是要降低男性医生的吸烟率,并加强对医院男洗手间的控烟管理。

[Objective]Through the monitoring of hospital indoor air PM2.5concentrations to understand the Shenzhen hospital for the situation of smoking intervention,and provide baseline data for tobacco control intervention.[Methods]PM2.5 concentrations monitoring was performed in 5 hospitals of Shenzhen City.The outpatient hall,hospital corridor,male bathroom,and the doctor’s office,the nurse’s office were selected as monitoring areas,with 5 related monitoring points in each area.The monitoring was performed during opening time.The PM2.5 concentration values were logarithmically transformed into normal distribution and then analyzed statistically by SPSS 10.0 software.[Results]The monitoring results showed that indoor air PM2.5 concentration was highest in male bathroom（53.35±50.60 μg/m3）,followed by doctor’s office（45.80±60.53 μg/m3） and nurse’s office（19.67±11.80 μg/m3）.Analysis of variance found the PM 2.5 concentrations were significantly different in different location（P〈0.05）.[Conclusion]The PM2.5 concentration in hospital corridor,male bathroom and doctor’s office is higher than that in nurse’s office.The government policy intervention is the guarantee of tobacco control.Hospital tobacco control should focus on reducing the smoking rate of male doctors and strengthening the management of male bathroom.
