Fungi growth in buildings

The results of research into occurrence of fungi in buildings are hereby presented. Indoor air pollution balanced between 10(2)-10(3) cfu/m3. Examined building surfaces have been found significantly mouldy. Total number of fungi ranged from 3.28 x 10(5) to 9.75 x 10(10) cfu/100 cm2. The results of the research show the active development of this group of microorganisms. In rooms, over 30 fungi species belonging to 11 genera have been detected. The most frequently occurring ones were fungi genera: Cladosporium, Penicillium, Aspergillus and Acremonium. Among those, potentially toxinogenic species have been separated (Aspergillus ochraceus, Cladosporium cladosporioides, Penicillium chrysogenum, Penicillium notatum). Apart from micotoxins they have been found to produce huge amounts of conidia which can cause allergy in sensitive people. Hence, people should definitely avoid fungi in their environment.
