Diversidade de bioaerossóis presentes em ambientes urbanizados e preservados de um campus universitário

Abstract

The bioaerosols are particles of biological origin suspended in the air, having as important constituents the airborne fungi. The knowledge of the airborne mycota in a certain site is determinative for ecological diagnosis, measuring of air contamination and allergy treatments. This study was carried out to establish the mycota and verify possible impacts of seasonal differences on fungal community. For this, it was performed identification and counting of fungi colonies existed in the air environment of different sites at UECE/Itaperi Campus. The analyses carried through 50 air samples, which were isolated 4,086 colonies belonging to 18 genera, being the most incidents Aspergillus sp., Penicillium sp. e Fusarium sp. Positive relations between the number of colonies and the analyzed environments were observed, being the classroom the most biocontaminated environment, although correlations with seasonal changes were not observed. It was evidenced that the difference in air concentration should be more related to the unbalance in human activities than to the climatic conditions of the regio
