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.

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.

Nuapada, Jun 15: In a shocking incident, a 70-year-old elderly woman had to drag her 100-year-old bedridden mother on a cot to the nearby bank to withdraw pension money of Rs 1,500.

The incident came to light after a video of the woman dragging her bedridden mother on a cot to a bank in Odisha's Nuapada district went viral on social media.

The woman from Bargaon village dragged her mother on the cot after the bank official allegedly asked for physical verification. The incident took place on June 9.

"I went to the bank several times in last three months and requested the bank official to release the pension amount. However, the official informed that they would release the pension if I bring my mother to the branch," said Punjimati Dei.

Bank manager Ajit Pradhan allegedly asked Dei to bring her bedridden mother Labhe Baghel to the bank.

Her mother is an account holder under Jan Dhan Yojana of the Central government.

The Centre had announced Rs 500 monthly assistance for women Jan Dhan bank account holders from April to June in view of the COVID-19 situation.

A district administration official informed that the woman reached the bank with her mother before the manager could visit her home for the verification.

May 30: A Delhi court on Saturday granted interim bail for 10 days to former municipal councillor from the Congress Ishrat Jahan, who has been booked under the stringent Unlawful Activities (Prevention) Act, to get married.

She has been booked under the anti-terror law in a case related to communal violence in northeast Delhi in February.

Additional Sessions Judge Dharmender Rana granted the interim relief from June 10 to June 19 to Jahan on furnishing two sureties of Rs 1 lakh.

The court directed her not to tamper with any evidence or influence the witnesses in the case.

According to the interim bail plea, filed through advocates S K Sharma and Lalit Valeecha, Jahan's marriage was fixed in 2018 for June 12, 2020.

The plea further said that Jahan would not tamper with any evidence or influence the witnesses if granted bail.

The petition, also filed through advocates Tushar Anand and Manu Prabhakar, claimed that Jahan has been falsely implicated in the case.

It alleged that upon bare perusal of the contents of the FIR, no incident of violence can be attributed to her and the wild and baseless allegations made against her were not only irresponsible and false, but also caused serious harm to her reputation.

Jahan, who is also an advocate, was only a supporter of ongoing peaceful protests and it was one of the fundamental rights of the citizens to protest and register their dissent against any unreasonable measure of the government, the plea said.

Besides Jahan, Jamia Millia Islamia University students Asif Iqbal Tanha, Gulfisha Khatoon, Jamia Coordination Committee members Safoora Zargar, Meeran Haider, president of Jamia Alumni Association Shifa-Ur-Rehman, suspended AAP councillor Tahir Hussain, activist Khalid Safi, JNU student Natasha Narwal and former student leader Umar Khalid have also been booked under the anti-terror law in the case.

The police had claimed in the FIR that Khalid and his associates had instigated people to start riots in the area and it was a "premeditated conspiracy".

Communal clashes had broken out in northeast Delhi on February 24 after violence between citizenship law supporters and protesters spiralled out of control, leaving at least 53 people dead and around 200 injured.
