A total of 69 isolates of yeasts were recorded in the indoor air of the school buildings: 43 in heated rooms and 26 in unheated rooms. Perfect stages prevailed. Fungi isolated in our study belonged to 39 species. These were mostly monospecific isolates although five two-species isolates were noted. Differences in the properties of physiological characters of fungi isolated in both study seasons were observed. As indoor and outdoor air does not mix during the heating season, a specific substrate for prototrophic, non-fermenting yeastlike fungi forms. Acid production allows fungi to dissolve inorganic compounds in building structures and to release needed microcomponents. Abilities to produce carotenoid pigments are clearly promoted in yeast-like fungi living indoor. This may be related to the accumulation of compounds that are indirect stages in the cycle of biosynthesis of carotenoids or a surplus of oxidizing compounds.

We performed measurements in 16 houses (12 concrete-slab houses and 4 brick houses) and within each house we performed measurements in one or more rooms from cellar to 4th floor. In total, the study includes 279 indoor radon measurements. The method of alpha track detectors was used in this investigation. The measurements were performed in housing of the same construction of concrete slabs in one part of Białystok. Approximately 12 million people in Poland live in such concrete slab buildings. It was observed that mean radon concentrations in brick houses were higher (by 24%) than in concrete slab buildings situated in the same housing estate. The results for the Green Hills housing estate are believed to be representative for all concrete slab buildings in northeastern Poland.

The aim of this study was to test the air in a single hospital department for fungal contamination. The department included three fully protected rooms with laminar air flow, comprising a bone marrow transplant unit (BMTU) and eleven naturally ventilated patient rooms of a haematology unit (HAEMU). Air samples were taken with an IDEAL air sampler (bioMerieux) on Sabouraud dextrose agar plates. The concentration of fungi in the air of the HEPA-filtered rooms of the BMTU ranged from 0-75 CFU/m3. Penicillium and Cladosporium were dominant among the fungal biota in the whole department. Of aspergilli, A. fumigatus was prevalent and seasonal increases in the frequencies of A. clavatus and A. niger isolation were observed. The detection of potentially pathogenic species of Aspergillus and Mucor in the BMTU and an increased concentration of Aspergillus in the HAEMU (up to 200 CFU/m3) instigated the introduction of additional preventive measure besides routine disinfection, namely an exchange of the HEPA filters in the BMTU and the installation of equipment based on multifunctional ion technology in the HAEMU. In a subsequent examination, a diminished number of fungi in the air was observed. During the study, 2 cases of proven and 3 of probable aspergillosis (according to EORT criteria) were noted. There was no link observed between the higher concentration of Aspergillus detected in the hospital air and the development of the infection. The authors conclude that hospital air examination can be helpful in indicating problems with hospital air facilities, enabling the introduction of procedures improving air quality and subsequently diminishing the risk of nosocomial mycoses.

Aerobiological measurements were made by the volumetric method (VPPS Lanzoni and Burkard instruments). Concentrations of microscopic fungi were measured from April 16th to July 2nd, 2013, in two rooms of the Chair of Botany and Natural Environment Protection, Faculty of Biology, Szczecin University. The study was undertaken to perform mycological analysis of the air in selected rooms. Mycological contamination of the air in the surveyed areas was not diverse in terms of species composition. Nearly three times higher concentrations of fungal spores were recorded in the seminar room. The most abundant were spores of fungi from the genus Cladosporium. The concentration of fungal spores of Cladosporium, Botrytis and Aspergillus/Penicillium exceeds the limits.

A study on indoor air microbiological contamination in various rooms of university buildings in Poznań, Poland, is presented. Investigations were conducted in the period September-October 2002 and the same period in 2003. Air samples were taken twice a day: in the morning and in the afternoon. In all of the tested places a multiple growth of bacteria and significant increase of mould spores was observed in afternoons. The predominant bacteria and moulds isolated from investigated air samples were: Staphylococcus spp., Micrococcus spp., Serratia spp., Aspergillus spp., Penicillium spp., Rhizopus spp., Cladosporium spp. and Alternaria spp. Among these microbes the presence of pathogenic and strongly allergenic microorganisms was detected.

The article presents the results of air temperature measurements inside a basement, outside it and in the ground adjacent to the building. The results and their analysis reveal that indoor thermal conditions develop differently in rooms with earth-contact structures. Intermittent heating exerts an important influence on the shaping of temperature conditions in a basement and its vicinity.
