An Experiment to Control Pollution Caused By Exhaust Gases of Automobiles

Exhaust gases from auto vehicles are the main source of air pollution, especially in urban areas. These exhaust gases consist of oxides of nitrogen and carbon monoxide causing pollution of air and producing the disturbance to the dynamic equilibrium of nature. These gases are toxic to humans, animals and plants. To get rid of this problem the paper proposes a new device to check the entry of NO₂, NO and carbon monoxide into the atmosphere by connecting a specially designed fibre glass absorption chamber to the silencer of the auto vehicles. The chamber is divided into three parts and filled with such chemical which absorbs oxides of nitrogen, CO and carbon particles. This experiment is successful to check the CO and NO₂ pollution up to an extent.
