摘要:The microclimate of a room has an impact on human well-being, physical and mental health, on work productivity and the preservation of good health. Several dozen species of bacteria can live in buildings and more than 400 species of fungi (mainly Aspergillus, Cladosporium, Penicillium, Fusarium genus). The presented results are studies from different health department suggesting the desirability of systematic microbiological testing, evaluation of fungal pathogens, and involving staff, patients, walls, floors, furniture units (hardware, underwear), and air. However the problem is a lack of unified Polish standards, the classes of microbiological indoor air and the lack of harmo nization of existing rules for air sampling to assess air fungal pollution in the health care setting
