Abstract
To assess biological air quality, concentrations of viable airborne microbes were determined in hospital home and outdoor air from August 25 to October 18, 1990. Bacteria, fungi and thermophilic bacteria were sampled using gravitational and suctional sampling method. In bacteria groups, the Staphylococcus spp. was identified by microscopic examination and biochemical tests. Results of the study are as follows. 1. Results using the gravitational sampling method indicated that average numbers of airborne microbes in hospital home and outdoor air were 21.5, 12.2 and 17.6 CFU/plate, respectively. These levels are well within an appropriate standard of 50 CFU/plate suggested by Endo. 2. Results using the suctional sampling method indicated that total airborne microbe concentrations in hospital, home and outdoor air were 1,998, 1,363 and
