—In this study we used biomarkers for analyzing the impact of fungal spore in ambient aerosols collected from rural area of eastern central Indian region during winter 2011.Mannitol and arabitol were used as tracer to estimate the impact of fungal activity in the ambient aerosols in our study site. We present the first estimates for the impact of fungal spores to the ambient aerosols mass loading in the eastern central India. This biomarker are quantified in two particle size fraction i.e. PM2.5─10
(Coarse) and PM1
(Submicron). Mannitol is dominant over arabitol in both two size fraction during winter period. The mass concentrations of these two biomarkers were higher in coarse size fraction as compared to submicron sizes. Strong correlation was found between the mass concentration of mannitol and arabitol in coarse size fraction only, whereas other size fractions were moderately or poorly correlated to each other. These showed that the sources for mannitol and arabitol in coarse size fractionwere similar.
