This study was conducted to evaluate the characterization of airborne bioaerosol in public facilities in Seoul. A total of 17 public facilities were investigated from December, 2002 to February, 2003.
As results of the survey, the mean concentrations of bacteria and fungi in indoor air of public facilities were 378.08±296.33CFU/m3 by RCS and 106.38±171.63CFU/m3 and 347.46±335.32CFU/m3 and 95.23±62.61CFU/m3, by Six-stage cascade air sampler respectively. The mean concentrations of bacteria in indoor air (by ventilation method) were 517.14±343.93CFU/m3 of natural ventilation and 215,83±100.71CFU/m3 of mechanical ventilation. The mean concentrations of fungi in indoor air (by ventilation method) were 83.14±79.16CFU/m3 of natural ventilation and 133.50±248.07 CFU/m3 of mechanical ventilation. The mean concentrations of bacteria in indoor air were 449.44CFU/m3 for the ground and 217.50±103.68CFU/m3 for the underground. The mean concentrations of fungi in indoor air were 63.89±77.66CFU/m3 for the ground and 202.00±290.08CFU/m3 for the underground.
