colony-forming units
per cubic meter of air (CFU m3
). The fungal concentrations found at most of the indoor environments fell within the
specified guidelines of the American Conference of Government Industrial Hygienists (ACGIH), between 100 and
1000 CFU m3 for the total fungi. However, the indoor bioaerosol concentrations at most of the surveyed environments
exceeded the Korean indoor bioaerosol guideline (800 CFU m3
). Consequently, the current findings suggest
the need for reducing strategy for indoor microorganisms at the surveyed microenvironments.
