Question

State some measures of controlling air pollution at source.

Answer 1

1. We know that major sources of air pollution are vehicles and industries. Hence, for the control of air pollution we must regulate two pipes: one is the silencer of the vehicle and another is the chimney of the industry. If they both work according to the parameters of the standard emissions and emit strictly in accordance with prescribed limit then there won’t be any contamination in the air.
2. Emission rates should be restricted to permissible levels by each and every industry.
3. Using fuels with low sulphur and ash content.
4. Fuel substitution is another way of controlling air pollution. In many parts of India, petrol and diesel are being replaced by CNG fuelled vehicles. These are mostly adopted by vehicles that aren’t fully operating with ideal emission engines.
