Question

Write two important causes of air pollution.

Hint:

Vehicle and industrial emissions are key contributors to air pollution, and reducing these pollutants is essential for improving air quality and human health.

Answer 1

Two important causes of air pollution are:

• Vehicle Emissions: The combustion of fossil fuels in vehicles releases a variety of harmful gases such as carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter into the atmosphere. These pollutants contribute significantly to air pollution in urban areas.
• Industrial Emissions: Factories and industrial processes release large quantities of pollutants, including sulfur dioxide (SO₂), carbon dioxide (CO₂), volatile organic compounds (VOCs), and particulate matter. These emissions degrade air quality and contribute to smog and acid rain.
