某高校室内空气微生物调查及分析

Investigation and Analysis of Indoor Airborne Microbes in a University

为调查南昌某高校不同功能区室内场所空气质量状况,采用自然沉降法检测教学楼、实验楼、男生宿舍、女生宿舍、食堂和超市的室内空气微生物浓度,并对其空气质量进行评价.结果表明室内空气微生物整体变化幅度大呈现明显不同功能区差异,其浓度由多到少依次为女生宿舍>男生宿舍>食堂>教学楼>超市>实验室.室内空气微生物浓度的总平均值为375.00 CFU/m^3.依据《室内空气质量标准》评价为合格,同时参考中科院生态环境研究中心的标准评价为清洁,说明该校园室内空气质量好.

In order to investigate the air quality at different functional areas of a university in Nanchang,the indoor airborne microbes were monitored by natural sedimentation method in teaching building,lab building,boy's dormitory,girl's dormitory,canteen and supermarket.The results showed that the airborne microbes were obvious difference in different functional areas.The concentrations of airborne microbes decreased in the order of girl's dormitory>boy's dormitory>canteen>teaching building>supermarket>lab building.The total average in all samples were 375.00 CFU/m^3.According to the indoor air quality standard,the air quality was up to standard.Meanwhile,refer to the standard from research center for ECO-Environmental Sciences,Chinese Academy of Sciences,the evaluation result was cleanness.The indoor air quality was good in campus.
