ATMOSPHERIC CONCENTRATION OF FUNGAL BIOAEROSOLS OVER WHEAT FIELDS

Avinash V. Karne

Abstract

The present investigation was undertaken to understand the incidence of different fungal bioaerosols in the atmosphere over Wheat fields during Rabi Season by operating Volumetric Tilak Air Sampler. Altogether, 50 types of bioaerosols were identified of which 45 belonged to fungal spore origin and remaining 5 types belonged to group Other types. Out of the total 45 types, 27 belonged to Deuteromycotina, 11 to Ascomycotina, 3 to Basidiomycotina, 2 to Zygomycotina and 2 to Mastigomycotina. Bioaerosols obtained peak in the month of February with 34174/m3 of air and 25.9 spore percentage, when there was record of 24.6oC mean temperature, 51.8% mean relative humidity and 3.5mm rainfall. The allergenic and pathogenic nature of bioaerosols is discussed and the effect of prevailing meteorological parameters on these bioaerosols is presented in this paper.
