Air pollution discolouring Taj Mahal, finds study

December 11, 2014

Washington, Dec 11: A team of researchers from India and the US has found that the browning of the Taj Mahal's iconic marble dome and soaring minarets is due to dust and airborne carbon particles.taj mahal

"Our team was able to show that the pollutants discolouring the Taj Mahal are particulate matter: carbon from burning biomass and refuse, fossil fuels, and dust - possibly from agriculture and road traffic," said Michael Bergin, professor at the Georgia Institute of Technology in the US.

Attracting millions of visitors each year, the Taj Mahal became a UNESCO World Heritage Site in 1983.

Beginning in the 1970s, observers noted a brownish cast to the white marble that makes up the structures.

For the study, the researchers used air sampling equipment to measure what was in the air in the Taj Mahal complex from November 2011 through June 2012.

In addition, they also placed small samples of pristine marble onto the Taj Mahal at various locations near the main dome.

After exposure to air pollutants over a two-month period, the researchers found particles of dust, brown organic carbon and black carbon in the filters and on the marble samples.

The carbon particles come from a variety of sources, including fuel combustion, cooking and brick-making, trash and refuse burning and vehicle exhaust.

The dust may come from local agricultural activities and vehicular traffic - or from distant sources.

Now that researchers know what's discolouring the Taj Mahal, the next step will be to identify the sources of the particles and plan control strategies.

The sources could be local - and the government has already taken steps to reduce vehicle and industrial emissions in the area - or the particles could be coming from longer distances away from the region, the authors pointed out.

"Some of these particles are really bad for human health, so cleaning up the Taj Mahal could have a huge health benefit for people in the entire region," Bergin concluded.

In addition to Georgia Institute of Technology and University of Wisconsin in the US, researchers from the Indian Institute of Technology at Kanpur (IIT-K) and Archaeological Survey of India (ASI) collaborated on the project. The study appeared in the journal Environmental Science & Technology.

Lucknow, Jun 2: Bahujan Samaj Party chief Mayawati on Tuesday said protests in the US after the death of George Floyd, an African-American man, is a clear message to the world that a common man's life has value.

She said this is also guaranteed by the India Constitution, but the governments don't follow it, resulting in the current plight of migrants workers.

Floyd, a 46-year-old restaurant worker from Houston, died in Minneapolis on Monday after a white police officer pinned him to the ground. Video footage showed the officer kneeling on Floyd's neck as he gasped for breath, sparking widespread protests across the US.

"Floyd's killing by police and the 'Black lives matter' agitation in the US have given a clear message to the world that a common man's life has value and it should not be taken for granted," Mayawati said in a tweet in Hindi.

"India's constitution guarantees independence, security, self-respect and pride and governments should give special attention to it. If it was followed, crores of migrants labourers would not have to witness such bad days," she added.

She also demanded better coordination between states to check the spread of coronavirus and said Centre should intervene.

"While coronavirus patients are rising, there is lack of coordination between states and with the Centre, and allegation and counter-allegations are going on and sealing of state borders is unjustified and it is weakening the fight against the virus.  The Centre should intervene," she said in a separate tweet.
