Seasonality in quantity of atmospheric fungal aerosol in Tartu (Estonia)
The quantity of fungal spores collected in routine aerobiological monitoring of atmosphere in Tartu 1989–1994 was studied with respect to two aspects: daily mean concentration (measured as the number of spores in cubic metre of air in 24 hours), and spore totals of a period (measured as the number of spores in cubic metre of air in a period). The aerobiological calendar method was used to indicate seasonal character of the quantity of spores. During the 6-year period the main spore season occurred from March to November, the total annual amount of fungal spores exceeded 1×106 spores in cubic metre per year. The seasonal dynamics was expressed clearly in both daily mean concentrations of spores and seasonal spore totals.
