sulfur dioxide attack on marble Description

Effects of acid rain and sulfur dioxide on marble dissolution

Acid precipitation and the dry deposition of sulfur dioxide (SO2) accelerate damage to carbonate-stone monuments and building materials. This study identified and quantified environmental damage to a sample of Vermont marble during storms and their preceding dry periods. Results from field experiments indicated the deposition of SO2 gas to the stone .

Sulfur dioxide | SO2 - PubChem

Sulfur dioxide is a colorless gas with a pungent odor. It is a liquid when under pressure, and it dissolves in water very easily. Sulfur dioxide in the air comes mainly from activities such as the burning of coal and oil at power plants or from copper smelting. In nature, sulfur dioxide can be released to the air from volcanic eruptions.

Metal sulfur dioxide complex - Wikipedia

Sulfur dioxide forms complexes with many transition metals. For the most stable complex the metal is in oxidation state 0 or +1.. In most cases SO 2 binds in monodentate fashion, attaching to the metal through sulfur. Such complexes are further subdivided according to the planarity or pyramidalization at sulfur.

Art conservation and restoration - Sculpture | Britannica

Sulfur reacts in the atmosphere to form sulfur dioxide, which in turn combines with available moisture to form sulfuric acid. When in contact with marble or limestone (both of which are calcium carbonates), the sulfuric acid transforms the surface of the stone to gypsum (calcium sulfate). This transformation has several unfortunate results.
