Question

Air pollution is the contamination of air by pollutants. In this context answer the following:

How do industries pollute the air?

Answer 1

Industries pollute the air by releasing harmful gases and particulate matter during manufacturing processes. Factories burn fossil fuels, which emit carbon dioxide (CO₂), sulfur dioxide (SO₂), nitrogen oxides (NOx), and volatile organic compounds (VOCs). These pollutants contribute to smog and acid rain, and can cause respiratory problems. Additionally, industries that process materials like cement and metal often release dust and toxic metals, further degrading air quality and affecting health.
