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 5: Taking on Delhi Chief Minister Arvind Kejriwal after Shaheen Bagh shooter Kapil Baisala was identified as an AAP worker by police, BJP chief J P Nadda on Tuesday said it exposed the party and Kejriwal who were playing with the country's security.

The Aam Aadmi Party hit back, questioning the police investigation.

In a series of tweets, Nadda said people of the country and Delhi today have seen the "dirty face" of AAP.

"For political longing, Kejriwal and his people even sold the security of the country. Earlier, Kejriwal used to insult the Army and advocate terrorists, but today relations with those who carry out their terrorist activities came to light," he said.

Nadda said he wanted to make it clear to Kejriwal that this country is bigger than any election, any government, and "this nation will not forgive those who play with its security. Kejriwal and his entire team have been exposed. The people of Delhi will give a befitting reply".

He claimed the entire country has seen "photos of Imam Hussain, the MLA and former minister of the Delhi government, with a radical terrorist organisation, PFI".

Days before Delhi goes to polls, police claimed that Baisala is a member of the Aam Aadmi Party. They said Baisala joined the party in early 2019 along with his father.

Police said it had photos of Baisala purportedly joining AAP along with his father Gaje Singh last year.

AAP's Rajya Sabha MP Sanjay Singh alleged that photos which were part of investigation were leaked to the BJP. He also said the party will approach the Election Commission to raise this issue, which has cropped up four days before the polling date.

"On whose instance, the police is giving statement? How did the photos which were part of the investigation reach the BJP? Before the news came out, Manoj Tiwari in the morning stated that the accused was from AAP. How did Manoj Tiwari get this news," Singh questioned in a press conference.

Union minister and BJP's in-charge for the Delhi polls, Prakash Javadekar, in a press conference alleged that "their (AAP's) designs are very clear from the beginning and they are trying every trick".

The whole conspiracy of AAP is to "divide society, cause fear in a community and create a vote bank," he charged.

Javadekar also claimed that photos of Baisala were recovered by police from his mobile phone although they were erased.

He also claimed that Baisala and his father were welcomed by Sanjay Singh at their joining of AAP.

"This proves AAP misleads youth and pushes them on the wrong path. AAP's strategy is to divide two communities, they want to instigate riots in Delhi," Javadekar alleged.

He further alleged that AAP leader Sanjay Singh had said violence would take place in Delhi. Their "conspiracy has been exposed by Delhi Police," he claimed.

"We condemn this politics of AAP," he said.

Javadekar also claimed this was "not an isolated incident" as AAP member Amanatullah Khan made a "very provocative speech" and the party supported Shaheen Bagh and did not give permission for the prosecution of members of the "tukde-tukde gang".

He hinted the BJP could approach the Election Commission against AAP over the issue.

Hyderabad, Feb 26: Hyderabad Police on Tuesday registered a case against well-known poet Imran Pratapgarhi for his statement asking why there was "no Shaheen Bagh in Hyderabad".

According to Charminar Police, the complaint was registered by Sub-Inspector S Guruswamy, who was on duty at the QQ Stadium on February 24 where an Ehtaji Mishaira (Poetry Program) against the Citizenship Amendment Act, National Register Commission and National Population Register was held.

Permission for the said event was granted by Hyderabad Additional Commissioner of Police to the program organisers with certain guidelines including that poetry program should be held on February 24 from 6 pm to 9 pm, and no speaker should give provocative speeches in the program.

However, police said that the program was started by the organisers at 6 pm and continued till 9:48 pm even after police officers asked them to end the event by 9 pm. The program was attended by around 3,000 members at QQ stadium.

According to police, while addressing the meeting Pratapgarhi said: "Mujhe hairath hai us Hyderabad mein koi Shaheen Bagh kyu nahi hai (I am surprised why there is no Shaheen Bagh in Hyderabad)", which is "provocative" and may cause fear to any section of the public.

In this regard, a case has been registered against organisers for disobeying public servants' orders and the poet has been booked for delivering provocative statements under the relevant sections of the Indian Penal Code.

Further investigation is underway.

Meanwhile, Congress leader Mohammed Ali Shabbir took to Twitter to condemn the police action.

"Hyderabad Police booked a case against poet Imran Pratapgarhi for expressing surprise on why there is no Shaheen Bagh in Hyderabad. For police, this sentence is provocative. Is Shaheen Bagh not a part of India?," Shabbir tweeted.

"Shame on TRS Government and Hyderabad Police for targeting a poet for no-fault," he added.

Ahmedabad, Jul 23: Private schools in Gujarat have suspended online classes for an indefinite period from Thursday, after a state government order said they should not collect fees from students until the schools reopen.

In a notification issued last week, the Gujarat government directed self-financed schools in the state not to collect tuition fees from students as long as they remain shut in the wake of the COVID-19 pandemic.

It also asked these schools not to hike fees for the academic year 2020-21.

Unhappy with the move, a union of representing nearly 15,000 self-financed schools in Gujarat decided to put on hold online classes, an alternative arrangement started earlier this month for students.

Majority of these schools informed the parents through SMS on Wednesday night that there will not be any online classes for their wards from Thursday.

Self-financed School Management Association's spokesperson Dipak Rajyaguru on Thursday said almost all the self-financed schools in the state refrained from imparting online education.

"If the government believes online education is not real education, then there is no meaning of imparting such unreal education to our students. Online education will remain suspended until the government withdraws that notification," Rajyaguru said in a statement.

He said the association will also approach the high court against state government's decision.

Jatin Bharad, a prominent educationist and member of the association, said there is no alternative to online education in the present scenario.

"Self-financed schools need to pay salaries to the teachers and other staff. No state in India has taken such decision that fees cannot be collected despite conducting online classes. If we adhere to the state notification, it will be impossible for us to pay salaries and run the school.

Thus, we have decided to suspend the online classes," said Bharad said.
