Question

The Taj Mahal is being affected by:

• A. Noise pollution
• B. Air pollution
• C. Water pollution
• D. None of these

Hint:

The Taj Trapezium Zone (TTZ) was created to control air pollution around the Taj Mahal by restricting industries and vehicular emissions.

Answer 1

The Correct Option is B

Step 1: Identify the environmental problem associated with the Taj Mahal. The Taj Mahal, made primarily of white marble, has been observed to turn yellow and develop stains over time.
Step 2: Understand the cause of damage. Air pollutants such as:
sulfur dioxide,
nitrogen oxides,
particulate matter, released from nearby industries, vehicles, and refineries react with moisture in the air and cause acid rain.
Step 3: Effect of air pollution on the monument.
Acid rain corrodes marble,
Leads to yellowing and surface damage,
Reduces the aesthetic and structural quality of the monument.
Step 4: Eliminate incorrect options.
Noise pollution does not chemically affect marble.
Water pollution does not directly cause surface discoloration.
Hence, option (D) is incorrect. Therefore, the correct answer is \[ \boxed{\text{Air pollution}} \]
