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.

Thiruvananthapuram, Mar 29: Kerala Chief Minister Pinarayi Vijayan on Saturday expressed his concern over the ''non-cooperation from the Karnataka Government in removing the roadblocks erected by them in the roads bordering Malapuram district''.

Addressing a press conference at the Government Secretariat, the Chief Minister said, "Karnataka has not heeded to our request to remove the roadblocks. I have been trying to contact their Chief Minister B S Yeddyurappa but not able to reach him."

"We have briefed the Union Minister D V Sadananda Gowda and he has offered to resolve the issue. Our Chief Secretary has also briefed the Central Cabinet Secretary and we expect a resolution soon," he added.

New Delhi, Feb 11: The Aam Aadmi Party on Tuesday appeared to be heading back to power for a second term in Delhi with the party leading in 52 seats of the 70 and the BJP ahead in 18 as votes for last week's assembly elections were counted, according to Election Commission figures. The contest for political power over the national capital was a bipolar one with the Congress nowhere in the reckoning, according to initial trends.

AAP supremo and chief minister Arvind Kejriwal was leading in the New Delhi seat by 4,300 seats, while his deputy Manish Sisodia from Patparganj seat was ahead by 102 votes.

BJP leader Vijender Gupta, who is also leader of opposition in the Delhi legislative assembly, was trailing by over 1,200 votes from Rohini.

As early celebrations broke out in the AAP headquarters in Rouse Avenue, BJP's Delhi unit chief Manoj Tiwari asked his party supporters not to lose hope.

"There are 27 seats where the difference of votes is between 700 to 1,000," Tiwari told reporters.

Looking ahead at victory, he said he was not nervous and was ready to take on the responsibilities that a win would bring.

"All talk is over. We have to wait for the blessings of the people. I am confident it will be a good day for BJP. We are coming to power in Delhi today. Don't be surprised if we win 55 seats," Tiwari said.

Kejriwal, who had led his party to a spectacular win of 67 of 70 seats in 2015, is expected to address party workers and the media later in the day. However, his party workers were upbeat and in celebratory mode.

"We have been saying since the beginning that the upcoming polls will be fought on the basis of work done by us... You wait and watch, we will register a massive win," AAP spokesperson Sanjay Singh told reporters.

"We hope we get such a clear majority that a message goes out that doing Hindu-Muslim politics will not work anymore," said AAP volunteer Fareen Khan at the party office.

The headquarters were decorated with blue and white balloons and big cutouts of Kejriwal were placed in different parts of the office.

Labour minister and AAP's Delhi unit convenor Gopal Rai was leading in Badarpur constituency by 1,994 votes.

Atishi, AAP's Kalkaji candidate, who was also instrumental in the transformation of Delhi government schools, was trailing by 190 votes.

AAP's Timarpur candidate Dilip Pandey was leading by over 1,500 votes.

BJP's Tajinder Singh Bagga was trailing on Hari Nagar seat by over 50 votes, while AAP's Raghav Chadha is leading from Rajinder Nagar constituency.

Congress' Chandni Chowk candidate Alka Lamba, who is sitting MLA from the constituency, was trailing by over 5,800 votes.

Counting centres are spread across 21 locations in 11 districts, including at the CWG Sports Complex in east Delhi, NSIT Dwarka in west Delhi, Meerabai Institute of Technology and G B Pant Institute of Technology in southeast Delhi, Sir CV Raman ITI, Dheerpur in central Delhi, and Rajiv Gandhi Stadium in Bawana in north Delhi.

The assembly elections were held on February 8.

A total of 672 candidates, including 593 men and 79 women, were in the fray for the hotly contested, often divisive polls with the anti-CAA protests in Shaheen Bagh occupying centrestage towards the end of the campaign.

While the AAP, of course, put forward Kejriwal, Prime Minister Narendra Modi, home minister Amit Shah and Uttar Pradesh chief minister Yogi Adityanath were among those who extensively campaigned for the BJP.

The Congress, still recovering maybe from the death of its three-time Delhi chief minister Sheila Dikshit in July last year, got into campaign mode much later. Former prime minister Manmohan Singh and party leaders Rahul Gandhi and Priyanka Gandhi were among those who campaigned for the Congress.

London, Jul 10: India's Reliance will load its first cargo of Venezuelan crude in three months this week in exchange for diesel under a swap deal the parties say is permitted under the US sanctions regime on the Latin American country, according to a Reliance source and a shipping document from state oil firm PDVSA.

Washington has exempted some Venezuelan oil trade from sanctions when transactions are in exchange for fuel and food or to repay debts rather than for cash. But that trade slowed as the US tightened restrictions and refiners, shippers and insurers have been steering clear of Venezuela to avoid any risk they may fall foul of sanctions.

Washington aims to deprive Venezuelan socialist President Nicolas Maduro of his main source of revenue with the sanctions, which have driven Venezuelan oil exports to their lowest level since the 1940s.

Reliance gave the US State Department and the Office of Foreign Assets Control (OFAC) notice of the diesel swap and received word back that the policies that allowed the transaction were still in place, the Reliance source told Reuters.

Reliance has previously said that its supplies of fuel to PDVSA in exchange for crude were permitted under sanctions.

An oil tanker named Commodore would load the cargo of crude in Venezuela and ship it to India, the tanker's manager NGM Energy said.

"All details of the transaction and transportation were shared with US authorities, who confirmed that the U.S. policy authorizing such transactions remained in place," NGM Energy said in a statement to Reuters.

"The shipment is made in connection with the humanitarian exchange of oil for diesel fuel."

The Commodore is loading a 1.9-million barrel cargo of crude for Reliance at Venezuela's main oil port of Jose, according to an internal PDVSA cargo schedule seen by Reuters.

The Liberian-flagged Commodore was at the Jose Terminal on Thursday, ship tracking data on Refinitiv Eikon showed.

The US State Department, Treasury's enforcement arm OFAC, and PDVSA did not immediately respond to a request for comment.

Reliance has a swap deal to provide diesel to Venezuela in exchange for fuel but has not received a cargo of crude since April. Sources at Indian refiners told Reuters earlier this year they planned to wind down their purchases of Venezuelan oil to avoid any problems with supply due to sanctions.

Other long-time customers of PDVSA, including Italy's Eni and Spain's Repsol, have continued taking cargoes of Venezuelan crude this year under permission granted by the US Treasury Department to exchange the oil for diesel supply as part of debt repayment deals, according to sources from the companies.

NGM Energy also manages the Voyager I tanker, which the United States removed from its list of sanctioned vessels last week after NGM and the ship's owner Sanibel Shiptrade said they would increase measures to ensure vessels complied with international sanctions.

"Last month, NGM Energy SA adopted a firm policy of not allowing vessels under its commercial management to trade to Venezuela, or to carry Venezuelan petroleum cargoes, absent US government authorization," NGM said.

"NGM continues to stand by that pledge."
