Question

Which of the following is the major source of air pollution?

• A. Cotton mills
• B. Thermal power plant
• C. Petroleum refineries
• D. Nuclear reactors

Answer 1

Answer: (A)

Cotton mills

Air pollution is caused due to an increase in the levels of particulate or gaseous matter in the air. The major source of air pollution is the cotton mills. The cotton fibres and dust from the industries form the major source of particulate matter. Ash is the source of the solid wastes from thermal plants. Water pollution is caused due to waste water let out from the petroleum refineries. Nuclear reactors are the source of radioactive wastes.

So, the correct answer is option A.
