Tann, in The Archaeology News Network, reports on the pollution that’s turning the 366 year-old Taj Mahal yellow –

India’s white marvel, the Taj Mahal, is slowly turning brownish-yellow because of air pollution, says an Indo-US study which also identifies the pollutants responsible for the effect. It says the Taj is changing colour due to deposition of dust and carbon-containing particles emitted in the burning of fossil fuels, biomass and garbage. The study confirms what has been suspected for long – that Agra’s poor air quality is impacting India’s most celebrated monument.

The research was conducted by experts from US universities – Georgia Institute of Technology and University of Wisconsin – as well as Indian Institute of Technology, Kanpur and Archaeological Survey of India. The paper was published in the Environmental Science & Technology journal in December.

The findings can lead to targeted strategies to curb air pollution in and around Agra and more effective ways to cleanse the marble surface of the 366-year-old mausoleum, which remains by far the most visited man-made structure in the country with footfalls of more than 6 million in 2013.
