This study is aimed at quantitative assessment of air borne bioaerosol in public spaces. Indoor air quality is an important contributor because modern human beings spend most of their life time in indoor. Therefore the quantification of airborne bacteria and fungi in public spaces such as health centers, auditoriums, libraries, seminar halls and rest room/toilets in Bangalore university campus was carried out by following standard impaction method and reported as colony forming units per cubic meter of air (CFU/m3). The results of above study revealed that average total fungal count in health center was 1,256 CFU/m3 in air conditioned (A/c) Auditorium; it was measured as 175 CFU/m3, at in library 2523 CFU/m3 , in seminar Hall 395 CFU/m3. , in Toilets it was 1,416 CFU/m3. . The average Total bacterial bioaerosol measured at health center was of 654 CFU/m3, at air conditioned Auditorium (AC) it was 310 CFU/m3, in library 1,159 CFU/m3, in seminar hall 586 CFU/m3 and in toilet 1,438 CFU/m3 respectively. The indoor to outdoor ratio of fungal and bacterial aerosol were found to be equal to 0.005 or > 0.005. From the above study we can conclude that the bioaerosol concentration in indoor environment is comparatively less than outdoor but high enough to cause infection in indoor occupants.
