The Taj Mahal at Agra may be damaged by Sulphur dioxide. Sulphur dioxide is an atmospheric chemical that can react with water molecules and produce sulfuric acid. Acid rain causes sulfuric acid to precipitate and damage the building. Other pollutants such as nitrogen oxides and hydrogen sulfide are also responsible for acid rain.

Damage to the Taj Mahal

The pollutants in the air are nitrogen oxides, hydrogen sulfide, and sulphur dioxide. Sulphur dioxide and nitrogen oxides in the atmosphere react with water (falling as rain), and are converted into sulfuric and nitric acids (with water, oxygen, and other chemicals).

The marble of the Taj Mahal is made of calcium carbonate. Therefore, when sulfuric acid and nitric acid react with calcium carbonate, it turns the white color of the surface to light yellow. Due to this, the Taj Mahal is being damaged.

  • The acid rain when coming in contact with the Taj Mahal’s marble converts it into a powdery product and carries it away with itself. This condition is known as ‘marble cancer‘.
  • As the Taj Mahal is completely made of marble, there has been significant damage to it due to acid rain.
