Abstract
The aerodynamic diameter of an air borne particle is the key property in determining its respiratory deposition. The study aim to assess PM<sub>2.5</sub> level and its size distribution at 5 traffic junctions located along the lateral highway connected to NH-202. A cascade impactor has been used to measure the size function range of PM<sub>2.5</sub> apart from PM<sub>10</sub> of atmospheric dust particles in air being PM<sub>2.5</sub> is concern with respect to effect on human health and is able to tend deeply into the respiratory tract reaching the lungs. It is observed that weight % of PM<sub>2.5</sub> values are in the range of 40% - 60% of PM<sub>10</sub> and few values of PM<sub>2.5</sub> are exceeding the standards prescribed by CPCB. It is concluded that free flow of traffic is main concern and maintenance of road should be carried out during low traffic hours.
