Abstract
Outdoor regional concentrations of airborne fungal spores and fungal fragments were measured using the 7-day Lanzoni sampler. The daily and intradiurnal fluctuations recorded during the monitored period have been studied. The multiple regression analysis was performed in order to determine how much of the total variance in these concentrations could be explained by meteorological parameters. Daytime periodicity statistically significant was established only in a few cases. As the relative importance of the weather factors varied, they could not be ranked according to their effect.
Highlights
Over the past decades, attention to air pollution, occasioned by physical and chemical pollutants and by fungal spores and pollen grains, has increased
Concentrations of airborne fungal components Five basidiospore types, 1 oospores type, and 35 ascospore types were recorded in the outdoor air
Other fungal spore types that were observed in air samples included the anamorphs (44 genera)
Summary
Attention to air pollution, occasioned by physical and chemical pollutants and by fungal spores and pollen grains, has increased. Airborne fungal spores are considered an indicator of the level of atmospheric bio-pollution. Some spore types are of clinical importance due to the fact that they are considered allergenic (Ianovici, 2016a) A wide range of airborne fungi can inflict considerable agricultural losses worldwide as they act as plant pathogens (Rodriguez-Rajo et al, 2005). In Romania, studies on airborne fungi are extremely scarce. These studies have been conducted only in a few cities such as Timisoara, Brasov, Bucharest, Craiova, and Cluj-Napoca (Ianovici et al, 2013). As far as western Romania is concerned, it is wellknown that the number of airborne fungal spores is maximal during summer. Other major spore types were quantified and classified: Alternaria, Fusarium/Leptosphaeria group, Helminthosporium, and airborne fungal fragments (Ianovici, 2017)
