Bioaerosols are particularly sensitive to sterilization processes due to their biological characteristics. Phenomena occurring in the atmosphere have major influence on airborne bacteria and fungi concentration levels. The presented study evaluates the sterilization properties of ambient air temperature and solar radiation on viable bioaerosols concentration levels in outdoor air in Gliwice, Poland. Assigned were the breakpoints indicating limited stimulation properties of the air temperature, which amounted 7.5°C for bacterial aerosol and 16.5 °C for fungal aerosol. Also revealed was the influence of solar radiation properties on decreasing the bioaerosols concentration levels. Both bacterial and fungal viable aerosol were sensitive to this radiation, although the phenomenon was more effective for airborne bacteria.
