Explain the effects of acid rain on the Taj Mahal.

(N/A) large number of industries and power plants are located near the area of the Taj Mahal. They use poor-quality coal,kerosene,and firewood,which causes the air around the Taj Mahal to contain a fairly high level of sulphur and nitrogen oxides. This results in acid rain,which reacts with the marble $(CaCO_{3})$ of the Taj Mahal.
$CaCO_{3} + H_{2}SO_{4} \rightarrow CaSO_{4} + H_{2}O + CO_{2}$
Thus,this wonderful monument that has attracted people from around the world is being slowly disfigured,and the marble is getting discoloured and lustreless.
