What is smog and how it is formed?

In fact, smog is a combination of smoke and fog. Smog is the blackish color fog formed by the mixture of the fined pollutants and ground-level ozone. Because it is a mixture of different toxic gases with dust and water vapors.

How smog is formed in the atmosphere? Smog is formed when sunlight reacts with the atmospheric gases and fine particulate particles. Smog is a type of air pollution. During situations of temperature inversions when the wind is calm, smog may get trapped and remain over a place for days.

Sources of air pollution

  • Toxic gases emission comes from road dust and power generation.
  • Industrial combustion, smelting, and other metal processing cause a devastating effect on the environment.
  • Wood burning, land conversion and forest fires also add to air pollution.

  • Emission from the brick kiln
  • Open dumping and burning of waste
