describe the threat to the beauty of the taj mahal?
Acid Rain is a major threat to the beauty of Taj Mahal .When acid rain fall on the monument (that is completely made of marble), they react with marble to form a powder-like substance that is then washed away by the rain. The soot particles emitted from the Mathura oil refinery near Agra is leading to the yellowing of the marble. This phenomenon is known as marble cancer. When sulfur dioxide and nitrogen dioxide mix with water vapor they create acid rain which causes the yellowing of the marble that spoils the color of the Taj Mahal.
The industries located in and around Agra , like rubber processing , automobile , chemicals and especially the Mathura oil refinery , have been responsible for producing pollutants like sulphur dioxide and nitrogen dioxide . These gases react with the water vapour present in the atmosphere to form sulphuric acid and nitric acid . The acids drop down with rain , making the rain acidic . This is called acid rain . Acid rain corrode sthe marble of the monument . The phenomenon is called ' marble cancer ' . Suspended particulate matter , such as the soot particles emitted by Mathura oil refinery , has contributed towards the yellowing of the marble .
