Explain any three remedial measures to overcome the acute air pollution in our cities.
Answers (1)
Three remedial measures to overcome air pollution are:
i) Proper maintenance of automobiles along with use of lead-free petrol or diesel can reduce the pollutants they emit. Catalytic converters, having expensive metals namely platinum-palladium and rhodium as the catalysts, are fitted into automobiles for reducing the emission of poisonous gases. As the exhaust passes through the catalytic converter, unburnt hydrocarbons are converted into carbon dioxide and water, and carbon monoxide and nitric oxide are changed to carbon dioxide and nitrogen gas, respectively.
ii) Encourage more fuel-efficient four-wheelers with better mileage per liter through road tax and sales tax incentives in addition to CNG requirements. Citizens should opt for more efficient and smaller cars that can run on CNG as an alternate fuel.
iii) Use of solar power which substitutes the coal-based thermal plants which causes a lot of pollution.
