It has been widely realized that bioaerosols play a very important role in climate change through participation in the carbon cycle of the ecosystem and holding potential cloud condensation nuclei (CCN) as well as ice-nucleation (IN) activity. Also, they are responsible for causing many allergenic effects. Human exposure to bioaerosols through physical contact or inhalation may lead to adverse health effects like asthma, COPD (chronic obstructive pulmonary disease), whooping cough and sick-building syndrome, etc. Thus, it is of utmost importance to study their occurrence and effects in indoor and outdoor environments. However, despite being a very important area of research, bioaerosols have been studied little less over Indian region. Towards this, we have conducted a year-long campaign to study and document bioaerosols variability from central IGP. We observed large seasonal variability in the concentration of bioaerosols. Gram-negative bacteria (GNB), a source of endotoxin in ambient air, averaged at 180 ± 90 CFU/m3 during post-monsoon (October‒November); 200 ± 75 CFU/m3 during winter (December‒February); 75 ± 25 CFU/m3 during pre-monsoon (March-May) and 110 ± 60 CFU/m3 during SW-monsoon (June‒September).A parallel enhancement in GNB abundance was observed with the biomass burning emissions intensification period (t = 4.0, p < 0.05).
