Question

How does lighting of crackers cause pollution?

Answer 1

1. Air Pollution: The burning of crackers releases harmful gases like carbon dioxide (CO₂), nitrogen oxides (NOx), and sulfur dioxide (SO₂). These gases contribute to air pollution, making the air harmful to breathe, especially in densely populated areas.
2. Particulate Matter: Fireworks emit fine particulate matter (PM2.5) that can penetrate deep into the lungs, causing respiratory problems, especially in children and the elderly.
3. Noise Pollution: The loud explosions from crackers contribute to noise pollution, disturbing the peace and causing stress, anxiety, and hearing damage in some cases.
4. Chemical Pollution: Many crackers contain toxic metals like lead, cadmium, and barium. These can contaminate soil and water when they settle after the fireworks are lit.
