[Contribution to the aeromycological study in the atmosphere of the city of Granada (South of Spain): seasonal and daily variations.].
The seasonal and daily variations in the concentrations of certain fungal spores in the atmosphere of the city of Granada (South of Spain) have been studied. Sampling was carried out in 1994 using a Hirst-type volumetric spore trap. The spores analysed correspond to the genera Alternaria, Cladosporium (Cladosporium cladosporioides and Cladosporium herbarum), Fusarium, Stemphylium and Ustilago. The seasonal-variation data obtained indicate that most of these spores are abundant throughout the year, with the exception of Fusarium, which was only present in trace amounts. The maximum concentrations of Alternaria, Cladosporium and Stemphylium are obtained during two sharp peaks in spring and autumn, with the minimum values being recorded during the summer and winter months; Fusarium and Ustilago spores are most abundant in autumn and winter. Although intradiurnal-variation models vary from one taxon to the next, the highest levels are generally recorded after 12:00 hours, with maximum levels being obtained in the afternoon.
