Delhi Air Pollution Damages Red Fort, Study Finds
The Red Fort, a famous historical site in Delhi, is being damaged by air pollution.
Scientists found black crusts forming on the red sandstone walls.
These crusts contain pollutants from cars, factories, and construction.
This is causing the walls to flake and lose their intricate carvings.
The study shows that air pollution is the cause of the damage.
Researchers observed blistering, salt crystallisation and dampness.
Authorities are urged to take stricter pollution control measures to protect this heritage site.
