摘　　要：目的了解广州市办公大楼室内空气PM 2.5浓度水平和影响因素,为制定相关卫生标准及政策法规提供科学依据。方法选择广州市58家办公大楼进行PM 2.5浓度监测。每家办公大楼选取办公大厅、领导办公室、复印室、男洗手间4个监测区域,在每个区域的中央设置1个监测点,并设室外对照监测点1个,于办公时间进行监测。结果男洗手间的PM 2.5浓度最高,为(95.20±60.36)mg/m3;其次是领导办公室,为(78.53±63.72)mg/m3;浓度最低的是办公大厅,为(45.61±27.56)mg/m3,不同监测区域PM 2.5浓度差异有统计学意义(F=4.26,P<0.05)。男洗手间、领导办公室PM 2.5浓度均显著高于室外,差异有统计学意义(F=6.33,P<0.05)。结论男洗手间和领导办公室PM 2.5污染较为严重,可能与吸烟有关。应加强室内禁烟宣传及监督,控制PM 2.5污染。Objective To investigate the PM 2. 5 concentration and its impact factors in office building in Guangzhou. Methods PM 2. 5 concentration was tested in 58 selected office buildings in Guangzhou. The monitoring points were set in the center of Public office area,leader ＇ s office,copy room and Men ＇ s lavatory during office hours, with one outdoor point as control. Results Indoor air PM 2. 5 concentration was highest in men＇ s lavatory（ 95. 20 ± 60. 36） mg / m^3,followed by leader＇s office（ 78. 53 ± 63. 72） mg / m^3 and Public office was（ 45. 61 ± 27. 56） mg / m^3. PM 2. 5 concentration were significantly different in different area（ F = 4. 26,P〈0. 05）. And the PM 2. 5 concentration in men＇ s lavatory and leader＇ s office were significantly higher than the outdoor（ F = 6. 33,P〈0. 05）. Conclusions PM 2. 5 concentration in men＇ s lavatory and leader＇ s office were higher than those in public office area and copy room,which may be relate to tobacco pollution. More attention should be paid to tobacco control especially in men＇ s lavatory and leader＇ s room.
