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.

Mumbai, Jun 16: Saudi Arabia’s sovereign wealth fund, PIF, is all set to pick up a stake in Jio Platforms, which would complete 25% of Jio’s equity dilution to the investors, said a report by the Gulf News.

Jio Platforms is part of the Reliance Industries empire owned by Mukesh Ambani. The Public Investment Fund (PIF) will acquire 2.33% for an estimated $1.5 billion, the report said.

So far, Jio Platforms has raised investment from 10 different global investors in seven weeks, the latest being TPG Capital buying 0.93% equity for Rs 4,547 crore and private equity firm L Catterton picking up a 0.39% stake for Rs 1894.50 crore.

Jio Platforms has raised a total of Rs 1.04 lakh crore so far from leading global investors including Facebook, Silver Lake, Vista Equity Partners, General Atlantic, KKR, Mubadala, ADIA, TPG and L Catterton since April 22.

With PIF coming on board, Jio Platforms would have diluted 25% of its equity. That's the maximum they intend to dilute to financial investors, which includes Mark Zukerberg's Facebook.

Any new investors coming on board in future will have to be "strategic investors, a tech giant, for instance," said a source who was part of the deal-making process, the report said.

In recent days, Jio Platforms, which will merge telecom, content streaming, gaming and ecommerce features into its app, has seen Abu Dhabi's Mubadala and ADIA pick up significant stakes amounting to $1.2 billion and $750 million, respectively.

Reliance Industries' owner, Ambani, Asia's richest man, has been on an investor acquisition spree, with the likes of Facebook and private equity majors such as KKR and Silver Lake Capital investing in Jio Platforms.

The contours of the deal with Saudi Arabia's PIF was finalised during Ramadan. "It was always Mukesh Ambani's wish to have a special relationship with Saudi Arabia and the UAE," said Anshuman Mishra, a London-based confidante and family friend of the Ambani family of longstanding, Gulf News quoted as saying.

He has also worked extensively with Gulf sovereign wealth funds over the years.

"Saudi Arabia's coming in to close the financial investor round in Jio is indicative of the special nature of the relationship. This is also indicative of the multi-billion-dollar partnership announced last year with Saudi Aramco.

"This is a major success for the present Indian government's foreign policy initiative in the gulf and symbolic of India's significance in the GCC," it said.

Thiruvananthapuram, Mar 7: Kerala Chief Minister Pinarayi Vijayan on Saturday came down heavily on the BJP-led government at the Centre for imposing a ban on two Malayalam channels in connection with the Delhi violence reporting, saying an "undeclared emergency" was prevailing in the country.

Terming the ban as a "dangerous trend", the left leader said it was an indication of the coming dangers. "The Centre has made an infringement into the freedom of the press, crossing all limits. There is a threat that if anybody criticises RSS and Sangh Parivar, they will be taught a lesson," he said here in a statement.

The channels- Asianet News and MediaOne were suspended for 48 hours over their coverage of last month's riots in Delhi, with the official orders saying they covered events on February 25 in a manner that "highlighted the attack on places of worship and siding towards a particular community".

However, the ban was lifted on Saturday morning. Urging everyone to adopt a "democratic vigil" against such trends, the Chief Minister said the tactics of the Centre was to bring everyone under its control by instilling fear.

It was seen that such an approach had repeatedly been made on Parliament, constitutional bodies and judiciary in recent times, he said. Claiming that one of the reasons for the ban was criticism of RSS and the Delhi police by the channels, he said no one is beyond that. "How can it be illegal to criticise RSS? The Constitution guarantees the right of any citizen to express his opinion fearlessly," he said.

People have the right to know what is happening in the country and the media has the right and responsibility to report it, Vijayan said adding that the fourth estate should be allowed to act "freely and equitably". The ban on Asianet News was lifted at 1.30 am, while the ban on Media One was lifted at 9.30 am on Saturday, a source at the Ministry of Information and Broadcasting told PTI.

Sources said the two channels had written to the ministry seeking revocation of the bans, following which it was lifted. "Channel's reporting on Delhi violence seems to be biased as it is deliberately focusing on the vandalism of CAA supporters," the ministry order on Media One had said.

"It also questions RSS and alleges Delhi Police inaction. Channel seems to be critical towards Delhi Police and RSS." The ministry had ordered prohibition of transmission or re-transmission of Media One and Asianet News for 48 hours on any platform throughout India with effect from 7.30 pm on Friday to 7.30 pm on Sunday. The Congress and the CPI had flayed the government over the suspension of Media One and Asianet News, calling the clampdown as "stifling of media freedom".

Former chief minister Oommen Chandy said the ban on the two malayalam channels was an "affront" on the democratic rights of the media. The fourth estate is the pillar of democracy and attempts to suppress the media by the government is "extremely worrying", he said in a facebook post.

"I join all democratic minded citizens in strongly condemning such attempts to muzzle the media by the government," he said. Meanwhile, Press Club, Kerala Union of Working Jouranlists (KUWJ) and Kerala Newspaper Employees Federation (KNEF) took out a march to the General Post Office here against the Centre's action on the two channels.

Media personnel holding placards and raising slogans participated in the march against the centre's decision. Similar protests were held in various parts of the state.

New Delhi, Jan 9: JNU students who tried to march towards the Rashtrapati Bhavan on Thursday protesting the violence on the university campus were stopped by police and later detained.

The police also resorted to baton charge to control the mob who tried to block the traffic at Janpath. Using loudspeakers, the police also appealed to the crowd to maintain peace.

Before the students tried to proceed towards the Rashtrapati Bhavan, a delegation of JNU Students' Union and JNU Teachers' Association also met Human Resource Development (HRD) Ministry officials and demanded the removal of Vice-Chancellor M Jagadesh Kumar from his post.
