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.

Simultaneously, non-subsidised cooking gas LPG rates were increased by Re 1 to Rs 594 per 14.2-kg cylinder in the national capital. Prices were up by Rs 4 in other metros mostly because of different local sales tax or VAT rate.

On the other hand, petrol and diesel prices were unchanged for the second day in a row.

This, after diesel rates scaled a new high after prices were hiked 22 times in just over three weeks.

In Delhi, a litre of petrol comes for Rs 80.43 per litre, while diesel is priced at Rs 80.53 per litre.

Rates vary from state to state depending on the incidence of local sales tax or VAT.

While the diesel price had been hiked on 22 occasions since June 7, petrol price had been raised on 21 occasions.

The cumulative increase since the oil companies started the cycle on June 7 totals to Rs 9.17 for petrol and Rs 11.14 for diesel.

Wayanad, Mar 3: Anguished over the alleged delay in receiving flood relief from the Kerala government, a 42-year-old man committed suicide in Wayanad district, police said on Tuesday. Sanal Kumar, a native of Thrikaipatta in Meppadi near here was found hanging inside the temporary shelter built by his friends and local people on Monday. He was among the hundreds who had lost their homes in the August 2019 floods.

His home, built on a three cent plot, had been damaged partially in 2018 floods and completely in the 2019 deluge. Family members of the deceased alleged that it was due undue delay on the part of the authorities in allotting funds for rebuilding his house that drove Kumar to take the extreme step. Kumar was hoping to get a house under the Life Mission project, sources said.

A relative said Kumar had only 3 cent of land and had lot of debts. Even the Rs 10,000 assistance promised by the state government for the flood affected, had not reached him. Since the past two years he had filed several applications for assistance and apporached many revenue authroties for the promised government assistance, but it never came, the locals alleged.

According to K K Sahad, president of Meppadi Panchayat the deceased had some other financial issues and it was not the delay in rehabilitation that made him commit suicide. "It is true that he was not included in the first list of beneficiaries under the LIFE project as he had to have "pattayam" (land records) for his land.

However, he was included in the second list, thanks to the dilution in the norms that possession was enough for those who had no 'pattayam' for their property. The amount of Rs 4 lakhs was sanctioned for him, but was delayed a bit due to some technical issues."

Wayanad MLA C K Saseendran described it as an "extremely sad" development. As Kumar had some difficulties in producing the land recrods, the authroties had been unable to include his name in the LIFE housing scheme in the first phase.

The matter has been brought before the notice of the revenue authorities, he said. Vythiri Tahsildar, Abdul Hameed, visited Kumar's relatives this morning as the family members of the deceased wanted his presence before the body was taken for post-mortem.

"There was some technical issues with regard to the land as it falls within the adhivasi reserve. But they were occupying it for long. However, the issue has been sorted out and that his family members would be getting the eligibility amount of four lakhs," Hameed said.

Srinagar, Feb 9: Authorities on Sunday snapped mobile internet services in Kashmir as a precautionary measure to prevent any law and order disturbance on the seventh death anniversary of Parliament attack convict Mohammad Afzal Guru, officials said.

The mobile internet services were suspended early in the morning as the authorities apprehended violence in the valley in view of the bandh call given by separatist outfits, the officials said.

The authorities had restored 2G internet services in Kashmir on January 25, more than five months after snapping all communication facilities in the valley following abrogation of Article 370 on August 5 last year.

Police on Saturday lodged an FIR against the banned Jammu Kashmir Liberation Front (JKLF) for calling a strike on Afzal Guru's death anniversary.

Guru was hanged in 2013 inside Tihar jail for his role in the Parliament attack in December 2001.

Two journalists were summoned by police for reporting the JKLF press release, which had called for strike on Sunday and Tuesday -- the death anniversary of the outfit founder Mohammad Maqbool Bhat.

They were let off after five hours of questioning. Bhat was hanged in 1984 and is buried inside Tihar jail.

Meanwhile, normal life in Kashmir was affected due to the strike, the officials said.

Markets and business establishments remained closed, while public transport was largely off the roads, they said.

There have been no reports of any untoward incident from anywhere in the valley so far, the officials added.
