Assessment of bioaerosol pollution over Indo-Gangetic plain.
Aerosol plays a very important role in climate change and public health. It affects cloud condensation nuclei and causes a number of epidemic diseases. The correlations of aerosol with epidemic diseases are due to the biotic components of aerosol. The present study deals with the measurements and characterization of bioaerosol over Indo-Gangetic plain. The levels of PM10 and PM2.5 are much higher than the recommended value set by NAAQS in India. Bacterial and fungal concentrations are in the reported range. Bacterial concentration is higher than fungal concentration. Gram-positive bacteria contribute 75% while gram-negative bacteria contribute 25% only. A total seven types of fungi are identified in aerosols. Aspergillus niger is dominant. Meteorological parameters play important roles in growth and presence of microorganism in the air. Bacterial concentrations are governed mainly by temperature while fungal concentration is influenced by relative humidity.
