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.

Ahmedabad, June 6: Rattled by resignations of three MLAs ahead of the June 19 Rajya Sabha polls, the Congress in Gujarat on Saturday shifted several of its legislators to resorts and bungalows near their constituencies to thwart any "poaching" bid, a party leader said.

With the resignations of Akshay Patel and Jitu Chaudhary on June 3 and that of Brijesh Merja on June 5, the Congress' strength in the 182-member House has been reduced to 65.

The effective strength of the House, however, stands at 172 as of now as ten seats are currently vacant - two due to court cases and the rest because of resignations.

While several MLAs from north Gujarat were shifted to a resort near Ambaji in Banaskantha district, those from south and Central Gujarat were moved to private bungalows in Anand, Congress spokesperson Manish Doshi said, adding that legislators from Saurashtra region were shifted to a resort in Rajkot.

India will suspend all domestic flights from midnight Tuesday, the final piece of a nationwide lockdown that threatens Prime Minister Narendra Modi’s attempts to revive an economy already expanding at the slowest pace in more than a decade.

The flight ban compliments a cancellation of all passenger trains through March 31, as authorities try to halt the spread of the coronavirus in the world’s second-most populous country, which has poorly equipped hospitals and inadequate social security. Modi on Monday held a conference call with some of India’s top entrepreneurs and bankers, who urged policymakers to immediately slash interest rates by as much as a full percentage point, transfer cash to the poorest citizens, and suspend loan-repayments.

Over the past three days, state after state has declared curfews and India’s international borders have been shut for most visitors since March 11. India so far has 492 virus cases, including nine deaths. But experts say the country could be on the same trajectory as Italy, where the outbreak quickly escalated, causing hospitals to overflow.

"This is the biggest lockdown in world history,” said Raghu Raman, a former soldier with the Indian Army and founder of the National Intelligence Grid, an umbrella database aimed at countering terrorism. “This strategic pause gives decision-makers more time to arrest the exponential spread of the virus and evaluate trade-offs.”

Controlling the outbreak is crucial for Modi, who remains India’s most popular political leader currently though his economic management has faced criticism. Foreign investors are selling Indian assets at an unprecedented pace and failure to contain deaths and infections could erode some of the prime minister’s personal appeal at home.

Oxford Economics slashed India’s January-March growth forecast to 3%, a number not seen even during the worst of the global financial crisis. The main equity gauge rose about 3% on Tuesday after a record 13.2% plunge Monday, and the rupee stayed near its all-time low.

“A part of the cerebral cortex that senses fear and survival seems to have activated in the minds of investors,” said Umesh Mehta, Mumbai-based head of research at Samco Securities Ltd. “The only relief in this market can come from either policy makers and regulators, or from some positive news that a cure for the pandemic is near.”

Bloomberg Economics estimates Modi’s administration needs at least 1% of gross domestic product -- $30 billion -- to meaningfully respond to the virus outbreak. Meanwhile, the nation’s billionaires are diverting their factories to manufacture medical equipment and pledging to keep paying their staff even as production grinds to a halt. India allowed companies to use their philanthropy funds to prevent the spread of the coronavirus.

Reliance Industries Ltd., controlled by India’s richest man Mukesh Ambani, has helped equip a hospital in Mumbai dedicated to patients of Covid-19, the disease caused by the coronavirus. It will also build quarantine centers and produce 100,000 facemasks a day and other personal protective equipment for health workers. The group’s telecom unit will offer free broadband to enable work-from-home during the lockdown and will pay its lowest paid workers twice a month to protect household incomes.

Ambani joins Mahindra & Mahindra Ltd. Chairman Anand Mahindra and Vedanta Resources Ltd. Chairman Anil Agarwal -- a combined worth of more than $40 billion between the trio -- who have so far made pledges.

Indian companies are responding to Modi’s shutdown call. Maruti Suzuki India Ltd., Tata Motors Ltd., Toyota Kirloskar Motor, Hero MotoCorp., Samsung Electronics Co. and LG Electronics Inc., Mahindra Group, TVS Motor Co., Kia Motors Corp., Renault Nissan Automotive India Private Ltd., and Yamaha Motor India are among companies that have announced factory suspensions.

Policymakers are aware of the risks of such a move. India -- with a record 5.9 trillion rupees of local corporate debt maturing this year -- faces “waves of default” if cash flows aren’t maintained, the government’s principal economic adviser Sanjeev Sanyal said an interview.

Finance Minister Nirmala Sitharaman last week said the government will announce a relief package for coronavirus-affected sectors as soon as possible. The Reserve Bank of India, which is due to review interest rates April 3, announced a 1 trillion rupee cash injection on Monday.

“Let me assure, whatever it takes to keep the cash flow going in the economy will be done,” Sanyal said. “We need to make sure that when we are past the health storm, we still have an economy that has not gotten gridlocked. Because unwinding that would be more difficult.”
