Airborne Fungal Spore Concentrations Research Articles

An aerobiological study of pollen grains and fungal spores of Barcelona (Spain)

A study of concentration of airborne pollen grains and fungal spores has been carried out in Barcelona (Spain) during 1989–90. The volumetric method of filtration, previously described for airborne pollen analysis (Suarez-Cervera and Seoane-Camba, 1983) has been used. In this case, the filters have also been cultivated in Czapecdox-agar, Sabouraud-agar and Sabouraud-agar with streptomycin for the identification of the fungal colonies. Analysis of the number of fungal spores growing on the filter shows that the maxima of colonies of spores developed in culture per m3 of air filtered, correspond to September–December. Pollen and spore concentrations start from November–December, reach a maximum in March–April and decline progressively until September–October. Therefore, in the city of Barcelona, the greatest concentration occurs in spring and the lowest in autumn.
