Numerous studies have focused on occupational and indoor environments because people spend more than 90% of their time in them. Nevertheless, air is the main source bacteria indoors, outdoor exposure also crucial. Worldwide indicated that bacterial concentrations vary among different types environments, with considerable seasonal variations as well. Conducting comprehensive monitoring atmospheric aerosol very important not only for environmental management but assessment health impacts pollution. To our knowledge, this first study to present changes bioaerosol data regarding an urban area Poland. This aimed characterize culturable populations Gliwice, Upper Silesia Region, Poland, over course four seasons (spring, summer, autumn winter) through quantification identification procedures. In study, samples were collected using a six-stage Andersen cascade impactor (with aerodynamic cut-off diameters 7.0, 4.7, 3.3, 2.1, 1.1 0.65 μm). Results showed concentration airborne ranged from 4 CFU m-3, measured one winter day, maximum equal 669 m-3 spring day. The average size period was 199 m-3. maximal seasonally averaged found season reached 306 minimal 49 most prevalent outdoors gram-positive rods form endospores. Statistically, meteorological factors related viability temperature UV radiation. These results may contribute promotion implementation preventative public programmes formulation recommendations at providing healthier environments.
