Yellowing of a historical monument, the Taj Mahal at Agra, was attacked by acid gases due to emissions of oxides of sulfur (SO_x) from foundries, coal‐fired power plants, chemical and hazardous industries, and oil refinery. The sulfur dioxide emitted from these industries, combined with atmospheric oxygen in presence of moisture and sun, formed sulfuric acid called “acid rain” affecting the marble of the Taj Mahal (Mehta 1987).
