The aerodynamic diameter of an air borne particle is the key property in determining its respiratory deposition. The study aim to assess PM 2.5 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 2.5 apart from PM 10 of atmospheric dust particles in air being PM 2.5 is concern with respect to effect on human health and is able to tend deeply into the respiratory

It is observed that weight % of PM 2.5 values are in the range of 40% -60% of PM 10 and few values of PM 2.5 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.
