Abstract: Spectrum of allergenic fungal spores in the atmosphere of Lisbon Outdoor airborne fungal spores may cause respiratory allergic diseases in humans. The genera Alternaria and Cladosporium are referred by several authors as the most common and prevalent allergenic fungi distributed in atmosphere. Monitoring of these fungi and the knowledge on the influence of climate on their distribution and abundance are important contributions to the elaboration of calendars of occurrence. The present work aimed at analyzing the seasonal variation in the concentration of spores of both fungal species and establishing relationships between meteorological parameters and their dynamics. The samples were collected in the city of Lisbon, between February 2009 and February 2011, with a volumetric Hirst-type trap. The assessment of effects of meteorological parameters was determined through multiple linear regression and application of the AIC criteria. Results confirmed the permanence of both fungi with a distinct predominance for Cladosporium. The highest concentrations of spores occurred in the months of June and July. Temperature and relative humidity of atmosphere were found to be the parameters best correlated with the abundance of those fungal spores in the atmosphere. Continuing of studies of this kind was considered to be recommendable to improve knowledge on the occurrence of these fungal spores in atmosphere.
