| Abstract: | In 12 selected flats in Sosnowiec, Upper Silesia, the concentrations of particulate aerosol, bioaerosol and bacterial endotoxin
were examined. Concentrations of particulate aerosol, bacteria, fungi and endotoxin were in the order of 101–102
μg/m3, 101–103 cfu/m3, 100–102 cfu/m3 and 10−2–10−1 ng/m3, respectively. The most numerous group of microorganisms in indoor air during the winter season were Gram positive mesophilic
bacteria. They were more common in flats polluted with tobacco smoke. The concentrations of airborne endotoxins were higher
in flats polluted with tobacco smoke in all size ranges. The highest level of endotoxins was found in the fraction of fine
particles below 5μm. |
