(a) Sulphur dioxide

(b) Chlorine

(c) Hydrogen

Taj Mahal at Agra may be damaged by Sulphur dioxide. Sulphur dioxide is an atmospheric chemical that can react with water molecules and produces Sulphuric acid. Because of the acid rain, the Sulphuric acid gets precipitated and damages the building. Other pollutants like nitrogen oxides and hydrogen sulphide are also responsible for acid rain.

Reasons for Damage to the Taj Mahal at Agra

The pollutants in the air consist of nitrogen oxides, hydrogen sulphide, and sulphur dioxide. The sulfur dioxide and nitrogen oxides in the atmosphere react with water (falling as rain), and get converted into sulphuric and nitric acids (with water, oxygen, and other chemicals). The marble of the Taj Mahal is composed of calcium carbonate. So, when the sulphuric acid and nitric acid react with the calcium carbonate, it decolorizes the white color of the surface to pale yellow. Thus, damaging the Taj Mahal.

  • The Taj Mahal at Agra is made of Calcium carbonate, which has been decolorized from white to pale yellow on coming in contact with the sulphuric and nitric acids as a component of Acid Rain.

  • Sulphur dioxide has increased in the air because of industrialization. The rain (water molecules) reacts with Sulphur dioxide and forms sulphuric acid. The formed sulphuric acid reacts with the calcium carbonate and damages the surface.
