Question

Explain the role of industries in increasing air pollution.

Answer 1

Industries are one of the major contributors to air pollution as they release harmful gases, chemicals, and particulate matter into the environment. The main ways in which industries contribute to air pollution are:

1. Emission of Harmful Gases: Industries burn coal, petroleum, and other fossil fuels, releasing carbon dioxide (CO₂), sulfur dioxide (SO₂), nitrogen oxides (NO_x), and carbon monoxide (CO) into the air. These gases contribute to global warming, acid rain, and respiratory diseases.
2.  Release of Particulate Matter (PM): Industrial activities such as construction, mining, and manufacturing release fine dust and toxic particles into the air. These particles can cause lung diseases, heart problems, and environmental pollution.
3. Chemical Vapors and Toxic Fumes: Chemical industries, refineries, and fertilizer factories release volatile organic compounds (VOCs) and other hazardous chemicals into the air. These pollutants cause smog formation and health problems like breathing issues and skin diseases.
4. Burning of Industrial Waste: Many industries dispose of waste by burning plastics, rubber, and chemicals, releasing poisonous gases like dioxins and furans. This leads to cancer risks, water contamination, and environmental degradation.
5. Deforestation for Industrial Growth: Industries clear large forest areas for setting up factories and mining activities. Fewer trees mean less absorption of CO₂, leading to increased air pollution and climate change.
6. Industrial Transport and Logistics: Factories use heavy-duty trucks and machinery that burn diesel and release carbon emissions into the atmosphere. Ports, railways, and cargo transport contribute to air pollution through fuel combustion and vehicle emissions.
