The aerosolization process of fungal propagules of three species (Aspergillus versicolor, Penicillium melinii, and Cladosporium cladosporioides) was studied by using a newly designed and constructed aerosolization chamber. We discovered that fungal fragments are aerosolized simultaneously with spores from contaminated agar and ceiling tile surfaces.(More)
Studies of indoor bioaerosols conducted in Central and Eastern European countries, as a result of the scarcity of funding, mostly do not attain the level presented by similar studies in Northern America and Western Europe. For socio-economic reasons, most of the intense studies on indoor bioaerosols in Central and Eastern European countries were carried out(More)
The paper summarizes the current state of knowledge regarding the role of filamentous microorganisms (i.e., fungi and actinomycetes) and their submicrometer propagules (fragments) in formation of indoor bioaerosol. It discusses the importance of water damages in buildings and the role of humidity as a cause of fungal and actinomycetal contamination and(More)
Endotoxins and β-glucans are one of the major markers of microbiological contamination. As components of biological aerosols, they are ubiquitous in many environments. Numerous studies performed during the last three decades have proved that exposure to endotoxins and β-glucans could be associated with many diseases and/or adverse health outcomes. The aim(More)
The aim of this study was to determine the size distribution of bacteria and fungi occurring in the air of human dwellings. The concentration and size distribution of particulate aerosol, Gram-positive mesophilic bacteria, Gram-negative mesophilic bacteria and fungi were examined in 60 flats situated in the Upper Silesia conurbation, southern Poland. The(More)
BACKGROUND Despite numerous benefits related to the utilization of biomass as an alternative source of energy, the handling of biomass creates a risk for the power industry workers of exposure to harmful microbiological agents. The purpose of this study was to evaluate the exposure of the workers to such agents at a power plant co-firing biomass with coal.(More)
The aim of this study was to assess the exposure of library workers to biological agents based on quantitative and qualitative characteristics of airborne and settled dust microflora supplemented with the analysis of dust mite allergens. The bioaerosol sampling was carried out using a 6-stage Andersen impactor. The settled dust samples were collected from(More)
Asbestos fibres, when released into the air, can pose serious health hazards to exposed people. The aim of this study was to determine the concentration of respirable asbestos fibres in a highly urbanized and densely populated town, where asbestos-containing materials have been widely used in building constructions. Their presence and degree of corrosion(More)
The microbial quality of the working environment was assessed in winter in air-conditioned office buildings in Warsaw. The average indoor concentrations of bacterial and fungal aerosols were low (<10³ cfu·m⁻³), below Polish proposals for threshold limit values in public service buildings. Even during cold months, if the air-conditioning system works(More)
Nowadays, an inhalation of naturally generated aerosols has again become a widely practiced method of balneological treatment of various respiratory diseases. The aim of this study was to characterize the microbial aerosol of subterraneotherapy chambers at the Bochnia Salt Mine Health Resort in southern Poland. The measurements were carried out using a(More)
