Gases like Sulphur dioxide and nitrogen dioxide are responsible for destroying the beauty of Taj. These gases are emitted by Mathura oil refinery and other rubber processing, automobile chemical industries working in and around Agra. These gases react with moisture and produce sulphuric acid and nitric acid. These acids fall on earth along with rain due to which colour of white marble has started to fade and marbles are getting corroded.
Various measures are being taken to save the beauty of Taj. The Supreme Court of India has ordered the industries to switch over to cleaner and pollution free fuels. Automobiles have been ordered to use CNG and LPG as the fuel. Unleaded petrol will only be made available to be used as fuel in vehicles.
