Abstract

The aim of this study was the assessment of particles and bio-aerosols distributed within the building located in heavy traffic area. In this study we examined using particles (PM10, PM2.5) and bio-aerosols (TBC, Fungi) as metrics for air quality within a building located in heavy traffic area. The concentrations of particles and bio-aerosols were measured indoors and outdoors simultaneously using particles monitoring and Anderson samplers. Indoor PM10 and PM2.5 in the summer were 63.3-152.1 μg/m3 and 36.5-53.2 μg/m3, respectively. Indoor Bio-aerosols concentrations were always higher than outdoors. Indoor average bio-aerosols of both TBC and Fungi in the summer were 789.7 ± 237.6 CFU/m3 and 49.9 ± 19.3 CFU/m3 respectively. Higher level of outdoor PM10 is due to vehicle exhaust emissions and that affected PM10 concentrations on the 1st floor and underground parking lot. Also, high level of PM10 in any case and TBC on the floor within the building were mainly caused by air-conditioning and indoor sources. In this study we evaluated pollutants by comparing the level of particles and bio-aerosols within a building in which a ventilation system is not installed. The data also indicated that bio-aerosols vary significantly during the summer and between floors within the building. A long term investigations over all four seasons in the building are needed to assess the effect of seasonal weather patterns on indoor particles and bio-aerosols level.
