Question 10

How does lighting of crackers cause pollution?

Answer

Lighting of crackers significantly contributes to Air Pollution and Noise pollution.

  1. Air Pollution: Crackers release harmful gases like sulphur dioxide, nitrogen oxides, carbon monoxide, and particulate matter into the atmosphere. These reduce air quality and can cause respiratory issues.

  2. Noise Pollution: Loud explosions from crackers exceed safe decibel levels, causing hearing discomfort, stress, and disturbance to humans and animals.
