Question

Secondary pollutants are those pollutants that are not emitted directly in the atmosphere but are formed by chemical reactions.

Which one of the following areas is likely to have a high concentration of the secondary pollutants?

विकल्प

• A remote village in Meghalaya

• Mangrove forests in Sunderbans

• A tribal area in Rann of Kutch

• Area around the coal mines in Jharkhand

Answer 1

Area around the coal mines in Jharkhand

Explanation:

The area around coal mines in Jharkhand releases massive amounts of primary pollutants like nitrogen oxides and hydrocarbons. These primary emissions act as precursors that chemically react in the atmosphere under sunlight to form high concentrations of secondary pollutants like smog and ozone. The other options lack the heavy industrial activity required to trigger these chemical reactions.
