How is the Taj being affected by air pollution?
The Taj Mahal is one of the seven wonders of the world. The white marble is turning yellow, due to the deposition of the soot particles emitted from the industries. The release of gases like sulphur dioxide and nitogen dioxide leads to formation of acid rain. Acid rain corrodes the marble of the monument and causes marble cancer. The discolouring and corrosion of marble is decreasing the beauty of the Taj Mahal.
