Continuous aerobiological monitoring has been conducted in Rzeszów from2000-2002, using the volumetric method. On each microscope slide 1 horizontal band was analyzed, dividedinto 24 fields corresponding to hours. For the analysis, 10 easy to identify fungal spores were chosenfrom ones regarded as allergenic: Alternaria, Botrytis, Cladosporium, Drechslera (type), Epiccocum, Ganoderma,Pithomyces, Polythrincium, Stemphylium, and Torula. The results were statistically tested using the chi2test as well as the Kruskal-Wallis test and ANOVA. The results were used to develop a calendar of theoccurrence of fungal spores in Rzeszów. The spores occurred in the air throughout the whole year, butmaximum concentrations were usually reached in July and August. Two groups of taxa were distinguished.Alternaria, Cladosporium, Botrytis, Epicoccum, Ganoderma spp. and Drechslera belong to the first group,and their spores and conidia were characterised by high frequency and abundance in the air. Low SFI values(Seasonal Fungal Index) and frequency of below 50% occurred in the second group of taxa, i.e. Pithomyces,Polythrincium, Stemphylium and Torula spp. Conidia of Cladosporium spp. were the most frequent, SFI valueswere very high and average annual concentrations did not differ significantly throughout the 3 yearsof study. The research confirmed the overlap of the period of maximum concentration of allergenic sporesand the period of the domination of Poaceae and Artemisia pollen in the air.
