Abstract

Mean levels of airborne bacteria, airborne fungi, temperature,relative humidity and carbon dioxide in total 69 general offices were 426(±83) cfu/㎥, 234(±125) cfu/㎥, 25.9(±1.3) ℃, 57.7(±8.6) %, 422(±38) ppm, respectively. The I/O ratio of airborne bacteria and fungi was over 1 and there was no significant difference among temperature, relative humidity and carbon dioxide in total 69 general offices. In construction period, a concentration of airborne bacteria and fungi was significantly highest in general offices constructed under one year and over three years since construction, respectively (p<0.05). The concentration of airborne fungi in general offices located at basement was significantly higher than those located at ground (p<0.05). No significant difference of airborne bacteria and fungi in general offices was found regardless of installation of HVAC system (p>0.05). The dominant bacterial genera identified in general offices was Staphylococcus, followed by Micrococcus, Bacillus, and Corynebacterium while usarium, Penicillium, Aspergillus, Alternaria, Rhizopus and Mucor were identified as dominant fungal genera in general offices.
