Acid Rain Marble Cancer

The main causes of acid rain are gases called sulfur dioxide so2 and nitrogen oxides nox.

Acid rain marble cancer.

The slow corrosion or eating up of marble of a monument by acid rain is known as marble cancer. Statues and structures made up of marble and limestone are slowly corroded as the rain water containing the acids fall on them both sulphuric acid and nitric acid dissolve marble to form salts acid rain corrodes the marble of the monument this phenomenon is also known as marble cancer.

The rainwater falls on them. Also when it rains the oxides of sulfur and nitrogen present in air react with it to form. Stone surface material may be lost all over or only in spots that are more reactive. This phenomenon is called as marble cancer.

Statues and structures are made up of marble limestone etc are slowly corroded as acidic. My answer might not give an accurate answer to this question but can definitely add some perspective to it. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. The main cause of marble cancer is acid rain.

Various gases like sulphur dioxide oxides of nitrogen are released from factories. Acid rain corroded the marble of the monument. Both sulphuric and nitric acid dissolve marble from salts. The acids present in the acid rain react with the marble of monument and corrode it slowly.

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. The phenomenon of marble cancer is due to acid rain. Causes of marble cancer. Presence of calcium carbonate in the acid rain.

These oxides absorb moisture from the air and get converted into respective acids and cause corrosion.
