This work presents the effects of fireworks display during Diwali on the short-term elevation of atmospheric aerosols and associated particle deposition in human respiratory tract at Dehradun, located in the foothills of the Himalayas. During Diwali in the years 2017 and 2018, the real-time particle number count (PNC) and particulate matter (PM) with the aerodynamic diameter of 0.01 to 35 μm were measured using an aerosol spectrometer.
