IIT Study Links Air Pollution to Accelerated Decay of Humayun's Tomb
A joint study by IIT Roorkee and IIT Kanpur found that air pollution is accelerating the deterioration of Humayun's Tomb in Delhi. The research identified a black crust mainly composed of gypsum forming on the sandstone due to reactions between sulphur dioxide and calcium-rich dust. This crust traps pollutants and weakens the stone, especially in rain-sheltered areas. The study recommends periodic removal of the crust, pollution monitoring, and evaluation of protective coatings to aid conservation efforts.
