Allergic sensitisation to fungi is associated with conditions including allergic fungal airway disease. Was determined between the meteorological variables and Pleospora and Aspergillus/Penicillium spore concentrations.įungal spores make up a significant proportion of organic matter within the air. Temperature and a significant positive correlation between the same and humidity and precipitation. There was a significant negative correlation between Agrocybe spore concentrations and daily mean There were significant negative correlations between airborne fungal spore concentrationsĪnd daily mean humidity. There were significant positive correlations between atmospheric concentrations of Alternaria, Cladosporium, Ustilaginales, and Dry air spores constituted a significant ratio of the total count (73.9%) in the atmosphere of Mardin. The highest atmospheric spore concentrations were observed in May and the lowest levels were determined It was determined that the dominant fungal spores included Cladosporium (51.5%), Ustilaginales A total of 43 taxa, hyphal fragments, and single septate ascospores were Turkey) in 20 using the volumetric method. The present study aimed to determine the fungal spores and their concentrations in the atmosphere of Mardin (southeast Airborne fungal spores are more homogeneously distributed in the air of the city, but their concentrations decrease more rapidly with height than pollen. Minimum air temperature was the primary meteorological factor affecting spore abundance, followed by relative humidity. Concentrations at the near-ground stations matched the grouping of the latter into stations of high, intermediate, and low urban green space. The attributes of the fungal spore season did not change in a consistent way among stations and years.

Differences in concentration and composition were far less pronounced among near-ground stations. The total concentration of the airborne fungal spores at 30 m was 10 times lower than near the ground. Cladosporium spores were dominant everywhere in the air of the city.

The effects of meteorological factors on airborne fungal spore concentrations were also explored. Air samples were collected at one rooftop station (at 30 m) and six near-ground stations (at 1.5 m) that differed in the size and composition of adjacent green spaces. We studied the diversity and abundance of the airborne fungal spores in the city of Thessaloniki, Greece, for two consecutive years. Ground level had significantly higher concentration of some important fungal aeroallergens but lower concentrations of others, suggesting that sampling height is one of the many variables that influence bioaerosol levels. By contrast, the rooftop sampler registered significantly higher concentration of Alternaria, ascospores, and other spores. The ground sampler had significantly higher concentration of basidiospores, Penicillium/Aspergillus-type spores, and smut spores than the roof sampler. Burkard slides were analyzed for fungal spores by light microscopy at a magnification of 1,000, and the results were statistically analyzed to compare the concentration of airborne fungal spores at the 2 levels. One sampler was located on the roof of a building at the University of Tulsa at 12 m above ground, and the second sampler was placed in the courtyard of the building at 1.5 m. To compare the concentration of airborne fungal spores at human respiration level (1.5 m above the ground) and at roof level (12 m height).Īir samples were collected using 2 Burkard volumetric 7-day recording spore traps from July 1 to October 31, 2005. It is necessary to estimate the concentration of airborne fungal spores at the human breathing level to evaluate the actual human exposure to outdoor aeroallergens. Airborne fungal spores are commonly collected from the outdoor air at the rooftop level of high buildings however, human exposure usually occurs nearer to the ground. Spores of many fungal species have been documented as important aeroallergens.
