Abstract
Airborne fungal spores constitute one of the important components of microbial population of ambient air. Aeromycological study was conducted for two years (January, 2012 to December, 2013) using Rotorod air sampler in the indoor air of certain residential dwellings in Thanjavur District, Tamil Nadu, India. During the present investigation, 15 fungal types were detected of which Trichoderma spores contributed highest concentration. Maximum concentration of fungal spores was observed in the month of August in 2012 and November in 2013 while minimum concentration was observed in the month of September in both years. Allergenically significant fungal spores responsible for serious health hazards were detected throughout the investigation period. Seasonal variation of airborne fungal spores was correlated with meteorological parameters.
Highlights
Fungi, especially filamentous fungi, which are common aeroallergens, form a major part of bioaerosols
The diversity and abundance of anemophilous microorganisms can be influenced by and can interfere with environmental conditions. These microorganisms are influenced by factors such as season, temperature, the relative humidity of the air and other parameters that exhibit seasonal variation (Gravesen, 1972)
Airborne spores detected were presented under two categories – fungal spores and other types
Summary
Especially filamentous fungi, which are common aeroallergens, form a major part of bioaerosols. It is important to know both the frequency of certain airborne fungi and their distributions according to the season and the main environment (i.e., indoor or outdoor) in order to evaluate their correlations with respiratory symptoms related to allergic processes (Tilak and Babu, 1983). These fungi can be used to assess effects on the environment and could contribute to determining the principal changes. In the light of the above facts, the present investigation was undertaken to detect the components of fungal airspora, their seasonal variations and possible sources from the indoor air of residential dwellings in Thanjavur District, Tamil Nadu, India
