Being one of the Seven Wonders of the World, the beauty and magnificence of the Taj Mahal attract tourists from all over the land.
However, in recent years there had been a significant diminish in the appearance of this masterpiece.
Pollution of the Taj Mahal:
The expulsion of Sulfuric dioxide() and Nitrogen dioxide() from the road traffic and nearby factories has been the cause of acid rain. Acid rain with the formation of Sulfuric acid() and Nitric acid() had degraded the morphology of the Taj Mahal by tarnishing its color to yellow and further eroding the structure.
The polluted Yamuna river flowing next to the Taj Mahal had been the cause of algae proliferation and various other insects like mosquitoes( the chironomids). The green droppings of these mosquitoes and the colouration due to algae had contributed to the brown color of the monument.
