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 27: The US Commission on International Religious Freedom (USCIRF) has said that the Delhi violence in which over 30 people were killed, was specifically targeted against the Muslims.

Expressing "grave concern over the ongoing violence taking place in Delhi", the USCIRF in a statement said that as President Donald Trump's inaugural visit to India winds down, North-East Delhi has been rocked by deadly rioting, with reports of violence and mobs specifically targeting Muslims.

"These incidents are even more concerning in the context of efforts within India to target and potentially disenfranchise Muslims across the country, in clear violation of international human rights standards," USCIRF Commissioner Anurima Bhargava said.

"According to reports, several mosques have also been set alight or vandalized. Many Muslim residents have been forced to flee the area. This unrest comes in the wake of widespread protests against the Citizenship (Amendment) Act following its passage in December 2019.

"The brutal and unchecked violence growing across Delhi cannot continue," Bhargava said adding that the Indian government must take swift action to ensure the safety of all of its citizens.

"Instead, reports are mounting that the Delhi police have not intervened in violent attacks against Muslims, and the government is failing in its duty to protect its citizens."

USCIRF Chair Tony Perkins said the ongoing violence in Delhi and the reported "attacks against Muslims, their homes and shops, and their houses of worship are greatly disturbing".

One of the essential duties of any responsible government, he said, is to provide protection and physical security for its citizens, regardless of faith.

"We urge the Indian government to take serious efforts to protect Muslims and others targeted by mob violence."

In its annual report last year, the USCIRF classified India as a "Tier 2" country for engaging in or tolerating religious freedom violations that meet at least one of the elements of the "systematic, ongoing, egregious standard for designations as a "country of particular concern (CPC)", under the International Religious Freedom Act.

The ongoing violence in North-East Delhi erupted after clashes between pro and anti-CAA protesters on Sunday.

Besides the casualties, over 200 others have been injured in the deadliest violence in the national capital in decades.

Thiruvananthapuram, Apr 20: Kerala Chief Minister Pinarayi Vijayan on Sunday alleged that efforts were being made to undermine the achievements of the state government in its fight against Covid-19 and said he was "ignoring" them as it was not the time for controversies.

The Opposition Congress has been raising allegations that a US-based company had been entrusted with the task of collecting data regarding the virus-infected patients in the state, in violation of fundamental rights.

"Many developed nations are in awe of the achievements of Kerala in its fight against Covid-19 pandemic. This is the speciality of Kerala model," Vijayan said. Referring to the data collection charge levelled by the opposition parties, Vijayan said some were engaged in slandering the state government.

"Those who think that the government should not have a reputation for effectively handling the coronavirus outbreak are engaged in slandering the state government. It has happened before, it's happening now also. This is not the time to go behind controversies. People are watching and they will evaluate," Vijayan said in his weekly interactive programme 'Naam munnott'.

He said he had decided to ignore such controversies. The ward-level committees, set up by the government for the anti-coronavirus fight, was collecting information of those under home isolation, elderly persons and those at the risk of the disease using a questionnaire in this regard and upload it on the server of the private agency. The Congress has alleged that the data, collected through the government machinery, was being uploaded not on the government server but on that of the foreign company.

Lucknow, Feb 16: Resident doctors at the AMU's Jawaharlal Nehru Hospital on Sunday demanded that the charges slapped against Dr Kafeel Khan under the National Security Act be withdrawn.

Dr Khan was arrested by the UP Special Task Force from Mumbai on January 29 in connection with a speech he had delivered during an anti-CAA protest at Aligarh Muslim University on December 12.

The Resident Doctors' Association (RDA) held a protest march on the hospital campus against the slapping of the NSA against the Gorakhpur doctor after he was granted bail in connection with the alleged hate speech.

RDA president Dr Hamza Malik said the move was a "blatant attempt to crush dissent and a violation of the Constitution of india".

He said by targeting the doctor, the UP government had done a great disservice to the entire medical community.

The AMU Students' Coordination Committee also described the decision to charge Dr Kafeel under the NSA a "direct assault" on a member of the medical fraternity who is "known for his upright behaviour and a champion of free speech".

Committee spokesperson and former AMU Students' Union president Faizul Hasan said by charging Dr Kafeel under the NSA even after he got bail was "a direct violation of a Supreme Court ruling on such issues".

Hasan said Dr Kafeel's fate should serve as an eye-opener for the rest of the country regarding the democratic rights in Uttar Pradesh.

The doctor was earlier arrested for his alleged role in the death of over 60 children within an week at the BRD Medical College in Gorakhpur in August 2017. Short supply of oxygen at the children's ward was blamed at that time for the deaths.

About two years later, a state government probe cleared Khan of all major charges, prompting him to seek an apology from the Yogi Adityanath government.
