Which of the following are essential components of industrial smog?

(A) Sulphur Dioxide (SO₂)

(B) Particulate matters

(C) Fly ash

(D) Soot

Choose the correct answer from the options given below:

The correct answer is - (A), (B), (C) and (D)

Key Points

• Sulphur Dioxide (SO₂)
  • It is a major component of industrial smog.
  • Produced by burning fossil fuels like coal and oil.
• Particulate Matters
  • These are tiny particles or droplets in the air.
  • Can include dust, dirt, soot, and smoke.
• Fly Ash
  • A byproduct of coal combustion in power plants.
  • Contains heavy metals and can contribute to air pollution.
• Soot
  • Consists of fine black particles, primarily composed of carbon.
  • Generated from incomplete combustion of fossil fuels.

Additional Information

• Formation of Industrial Smog
  • Occurs mainly in industrial areas where there is a high concentration of pollutants.
  • Involves chemical reactions between primary pollutants (like SO₂) and secondary pollutants.
• Health Impacts
  • Can cause respiratory issues such as asthma and bronchitis.
  • Long-term exposure may lead to cardiovascular diseases.
• Environmental Impacts
  • Leads to acid rain, which can harm ecosystems and water bodies.
  • Contributes to the degradation of buildings and infrastructure.
