Answers
Explanation:
Taj Mahal is slowly decaying due to air pollution. ... As the Yamuna River dries up, it risks sliding the Taj Mahal off its picturesque banks into a sea of mud. The burning of Municipal Solid Waste in open results in thick toxic smog which is the main reason for the discoloration of Taj Mahal.
Answer:
Researchers are pointing to air pollution to explain this progressive change of colour. Airborne particulate matter, made of black carbon, light-absorbing brown carbon and dust, have a brown tint that discolours the Taj Mahal's marble.
Explanation:
A unique UNESCO World Heritage site, the Taj Mahal is one of the most admired monuments and draws millions of tourists to India. In 2016, 6.2 million visitors enjoyed the architectural beauty of this mausoleum that was built in the 17th century as a tribute from the Mughal emperor Shah Jehan to his wife, Mumtaz Mahal. The ivory marble gives the Taj Mahal its iconic look, but there are growing concerns that it may not remain as bright white in the future. Its façade is turning into a brown-yellow colour altering the monument’s most distinguishing feature and climate change might speed up this process.
In India, tourism represents almost 10% of the GDP (2016), which shows that preserving highly visited sites plays in favour of this sector and of the overall economic development. In the state of Uttar Pradesh, where the Taj Mahal is located, the World Bank currently runs a tourism-focused project with an overarching development objective for communities living around tourist hubs. This reflects the connection of both aspects and shows that addressing air pollution issues would have environmental and economic benefits at the same time.
Damage to Taj Mahal (made up of marble) is caused by acid rain. Acid rain is rainfall and other forms of precipitation with a pH of less than 5. It consists of acids such as sulphuric acid and nitric acid. It corrodes metals, marbles, slate, stone etc. This phenomenon is called stone leprosy. Etching of marble occurs due to conversions of calcium carbonate of marble into calcium sulphate and calcium nitrate by H2SO4 and HNO3 respectively.
