ABSTRACT
Size distributed aerosols are collected from October 2016 to July 2017 at eastern central India. This work for the first time investigates the possibilities of long-range transport and inhalation dose of particulate matters in different size at study site. During winter the aerosols were enriched in fine mode particles size however, they are more enriched in coarse mode during summer and post-monsoon season. Significant loading of particulate matters was observed during summer season. Crop residues are burnt in large scale which increases fine particles in the atmosphere. Strong correlation between the fine size fraction were observed in summer and winter season which must be due to the strong biomass burning. The percentage loading of upper respiratory tract, respiratory tract and lungs were obtained to be 30, 69 and 52%, respectively during winter. High value of inhalation dose over entire study period may be responsible for severe health implications.
