what is a marble cancer?

The marble cancer refers to the corrosion of building and statues made up of marbles by action of sulfuric acid and nitric acid. The SO2 and NOx present in pollution get deposited on these buildings. These oxides absorb moisture from the air and get converted into respective acids and cause corrosion. Also when it rains the oxides of sulfur and nitrogen present in air react with it to form acid rain. This rain when fall on the monuments result in their corrosion by dissolving the calcium present in marble to make salt. Marble cancer causes disintegration and yellowing of the building or statue. Taj Mahal is losing its white shine because of marble cancer.

Marble marble cancer is cause due to chemical contents in the pollution mainly consisting of sulpher dioxide deposited on the marble surface absorbing oxygen and water vapor ,which would react with calcium in the marble stone forming surface disintegration and chaffing.

This is the yellowing of the Taj Mahal which is being caused by air pollution, especially sulphur dioxide. Combined with oxygen and moisture, sulphur dioxide settles on the surface of the tomb and corrodes the marble, forming a fungus that experts refer to as marble cancer.
