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.

As many as employees of Zee News have tested positive for the coronavirus, Editor-in-Chief Sudhir Chaudhary said on Monday. Most of them are asymptomatic, he said, tweeting an official statement from Zee News about the situation.

The organisation said that on May 15, one of its employees tested positive for the coronavirus. Following this, the company started testing employees who may have come in contact with the employee. Twenty-seven more were found to be infected.

“Fortunately most of them are asymptomatic and are not complaining of any discomfort,” Zee News said. “We believe this is because of early diagnosis and proactive intervention.”

The news network said all guidelines and protocols have been followed, and its office, newsroom and studios have been sealed for sanitisation. The Zee News team has been shifted to an alternative facility.

“At the moment, Zee Media Corporation has 2,500 employees, by far the largest in the private sector,” the company said. “We are committed to the safety of each one of them.”

Chaudhary also claimed that “those who are infected had the option of sitting at home and sharing memes”. “They came to work because they are committed professionals.”

Following this, some social media users claimed that Zee News employees found infected with Covid-19 were still at work. In response, Chaudhary alleged that a malicious campaign was being conducted to distort his statement. He said no infected employee had come to work, and all the contacts of the employee who tested positive on May 15 had been tested and quarantined.

Over the past two months, journalists from several media organisations have tested positive for the coronavirus. On April 21, 26 employees of a Tamil news channel based in Chennai tested positive for the coronavirus. The previous day, over 50 journalists from Mumbai were found infected, after samples of over 170 journalists were tested.

On May 7, a newspaper journalist died of the coronavirus in Agra. Some states, such as Uttar Pradesh, Karnataka and Delhi, have tested journalists for Covid-19.

United Nations, May 20: Highlighting India's long-standing history of promoting inclusive and peaceful societies, a top UN official on Tuesday voiced concern over incidents of "increased hate speech and discrimination" against minority communities in the country following the adoption of the Citizenship Amendment Act.

Under-Secretary-General and UN Special Adviser on the Prevention of Genocide Adama Dieng, however, welcomed Prime Minister Narendra Modi’s call for unity and brotherhood in the wake of the COVID19 pandemic.

Dieng said in a note to the media on Tuesday that he is "concerned over reports of increased hate speech and discrimination against minority communities in India" since the adoption of the Citizenship Amendment Act (CAA) in December 2019.

The Indian government has maintained that the CAA is an internal matter of the country and stressed that the goal is to protect the oppressed minorities of neighbouring countries.

The CAA, which was notified on January 10, grants Indian citizenship to non-Muslim minorities migrated to India from Afghanistan, Pakistan and Bangladesh till December 31, 2014, following persecution over their faith.

"While the objective of the act, to provide protection to minority communities is commendable, it is concerning that this protection is not extended to all groups, including Muslims. This is contrary to India’s obligations under international human rights law, in particular on non-discrimination,” Dieng said.

The Special Adviser recognised "India’s long standing and well recognised history of promoting inclusive and peaceful societies, with respect for equality and principles of non-discrimination.”

He also welcomed recent statements by Prime Minister Modi that the COVID-19 pandemic “does not see race, religion, colour, caste, creed, language or border before striking and that our response and conduct...should attach primacy to unity and brotherhood.”

Dieng encouraged the Government of India to "continue to abide by this guidance by ensuring that national laws and policies follow international standards related to non-discrimination and to address and counter the rise of hate speech through messages of inclusion, respect for diversity and unity.”

He further reiterated that he would continue to follow developments and expressed his readiness to support initiatives to counter and address hate speech.

The hate speech and the dehumanisation of others goes against international human rights norms and values, he added.

“In these extraordinary times brought about by the COVID-19 crisis it is more important than ever that we stand united as one humanity, demonstrating unity and solidarity rather than division and hate,” he said.

Dieng also expressed concern over reports of violence during demonstrations against CAA in some regions of India.

New Delhi, Feb 4: Miffed over the controversy created by its former Union minister and Uttara Kannada MP Anantkumar Hegde by his remarks against Mahatma Gandhi, the BJP, it was learnt, has issued a show-cause notice to him. The ruling party came under heavy criticism from the opposition over its MP’s remarks. The opposition has demanded a clarification from Prime Minister Narendra Modi over his party MP’s remarks.

Often in news for his controversial remarks, Hegde, sources said, could also be barred from attending the first parliamentary party meeting of the BJP of the budget session, scheduled on Tuesday. The party had taken a similar approach against its Bhopal MP Pragya Thakur during the last winter session for praising Mahatma Gandhi’s killer Nathuram Godse. Though the BJP leadership was earlier of the view that Hegde should tender an apology over his remarks but the party top brass, it was learnt, decided that it was not enough.

The Congress on Monday launched a scathing attack on the central government over the comments of BJP Lok Sabha MP Ananthkumar Hegde on Mahatma Gandhi. The party demanded that Prime Minister Narendra Modi come to Parliament and clarify his position on BJP leader’s “objectionable” remarks.

Congress party spokesman Anand Sharma said, “we can understand that why one after the other senior BJP leaders are insulting the memory of Mahatma Gandhi. They are disparaging the national movement, the freedom struggle because they are ideological descendents of those who were not only non-participants, but, actively opposed the freedom movement.” He further added, “Parliament is in session. We demand that the Prime Minister come to the House and make his position clear. As I have said, feeds that he is unhappy and angry, we are not concerned with that. In the very ideology, mindset, thinking and language of the BJP, there is violence.”

Asserting that the BJP MP’s statement was condemnable, Rajasthan Chief Minister Ashok Gehlot said the leaders of the saffron party could afford to call the freedom movement a drama as they never fought for the country’s independence. “Such statements reveal their true mindset that they use Gandhi's name just for show and have no regard for him,” he said.
