北京市丰台区地铁站台的空气卫生质量

Air quality of subway platform in Fengtai District of Beijing

目的了解地铁站台空气卫生状况,为地铁卫生管理提供依据。方法按照《公共场所卫生监测技术规范》要求,对北京丰台区内地铁站台空气中细菌总数、CO、CO2、风速、温度、PM10、甲醛和集中空调通风管道中细菌总数、真菌总数、积尘量进行监测。结果丰台区各站台空气中细菌总数、CO、CO2、风速、温度、PM10监测结果均符合要求;站台内不同监测点空气质量差异无统计学意义(P>0.05);换乘站站台空气中PM10浓度高于非换乘站台(P<0.05)。各地铁线集中空调通风管道内壁细菌总数、真菌总数和积尘量监测结果差异无统计学意义(P>0.05)。结论除温度外,丰台区地铁站台空气质量和集中空调通风管道卫生状况良好。

[Objective]To understand the air quality of subway platform,provide the scientific basis for the health management.[Methods]According to the Rules of health monitoring for public places,the total bacterial count,CO,CO2,wind speed,temperature,PM10,formaldehyde in air of subway platforms,as well as the total bacterial count,total fungi count and dust amount in central air conditioning ventilation ducts of subway platforms in Fengtai District of Beijing were monitored. [Results]The monitoring results of total bacterial count,CO,CO2,wind speed,temperature and PM10 in air of subway platforms met the standards, and there was no significant difference in air quality among different monitoring points（P〈0.05）. The PM10 concentration of transfer station platforms was higher than that of non-transfer station platforms（P〈0.05）. There were no significant differences in monitoring results of total bacterial count,total fungi count and dust amount in central air conditioning ventilation ducts among different subway lines（P〈0.05）.[Conclusion]Except temperature,the air quality of subway platforms and sanitary condition of central air conditioning ventilation ducts of subway platforms are good in Fengtai District.
