Microbiological contamination with fungi, including moulds, can pose a significant health hazard to those working in archives or museums. The species involved include Aspergillus, Penicillium, Geotrichum, Alternaria, Cladosporium, Mucor, Rhizopus, Trichoderma, Fusarium which are associated mostly with allergic response of different types. The aim of the(More)
OBJECTIVES The study was aimed at assessment of exposure to endotoxins, (1→3)-β-D-glucans and mite, cockroach, cat, dog allergens present in settled dust in premises of children as agents which may be significantly correlated with the occurrence of allergic symptoms and diseases in children. MATERIALS AND METHODS The study covered 50 homes of one-or(More)
BACKGROUND The aim of this study was to assess fungal air contamination in the processes associated with poultry breeding depending on the season. The evaluation was based on the determined concentrations of fungi and qualitative identification of isolated microorganisms. MATERIALS AND METHODS The study covered 2 hatcheries and 3 hen buildings. The air(More)
BACKGROUND The aim of the study was to assess the biological risks of medical laboratory employees with particular focus on laboratory acquired infection (LAI), activities having the greatest risk, accidents with biological material, post exposure procedure, preventive measures and workers' knowledge about biological exposure. MATERIALS AND METHODS The(More)
OBJECTIVES This study is aimed at evaluation of bacterial air contamination in intensive poultry breeding. The evaluation was based on the determined levels of bacterial concentrations and qualitative identification of isolated microorganisms. MATERIALS AND METHODS The study covered 5 poultry houses: two hatcheries and three hen houses with the litter bed(More)
BACKGROUND The effectiveness of health protection of workers occupationally exposed to biological agents is equally influenced by the workers' knowledge about the risks related to biological agents and the ways they behave at work. MATERIALS AND METHODS In this paper, the authors continue to present the results of the study covering 150 workers employed(More)
BACKGROUND In this paper the exposure assessment to airborne biohazards (organic dust, microorganisms, endotoxins and ((1 --> 3)-beta-D-glucans) as well as to ammonia and hydrogen sulfide among CAFO (swine farms) workers is presented. MATERIALS AND METHODS Occupational exposure assessment was carried out on 30 swine farms. Personal dosimetry was carried(More)
Medical diagnostic laboratories form a particular occupational environment, in which workers have contact with patients and potentially infectious biological materials thus it should be acknowledged that it poses a significantly increased risk to health of laboratory workers. The risk directly depends on the kind of microbes present in a biological material(More)
BACKGROUND The aim of the study was to recognize exposure to biological agents in the air of waste sorting plants. This publication contains the characteristics of technical solutions in use during sorting of waste and the results of quantitative analysis in terms of the presence of moulds and inhalable dust in the air. MATERIAL AND METHODS The study was(More)
In metalworking, the temperature of the cutting edge can reach 700 degrees C, which can adversely affect either the surface of the metal processed or the cutting edge itself. To reduce the heat and friction, the metalworking fluids and coolants are used. The most common are the oil-in-water emulsions, which are a mixture of concentrated mineral oils,(More)
