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, May 17: Following the COVID-19-induced economic disruptions, up to 135 million jobs could be lost and 120 million people might be pushed back into poverty in India, all of which will have a hit on consumer income, spending and savings, says a report.

According to a new report by international management consulting firm Arthur D Little, the worst of COVID-19's impact will be felt by India's most vulnerable in terms of job loss, poverty increase and reduced per-capita income, which in turn will result in a steep decline in the Gross Domestic Product (GDP).

"Given the continued rise of COVID-19 cases, we believe that a W-shaped recovery is the most likely scenario for India. This implies a GDP contraction of 10.8 per cent in FY 2020-21 and GDP growth of 0.8 per cent in FY 2021-22," the report said.

India's COVID-19 tally has crossed 90,000 and the nationwide death toll has touched nearly 2,800 so far.

The report titled "India: Surmounting the economic challenges posed by COVID-19: A 10-point programme to revive and power India's post-COVID economy" said the 'collateral damage' of the forecasted GDP slowdown, will be felt most acutely in employment, poverty alleviation, per-capita income and overall nominal GDP.

"Unemployment may rise to 35 per cent from 7.6 per cent resulting in 136 million jobs lost and a total of 174 million unemployed. Poverty alleviation will receive a set-back, significantly changing the fortunes of many, putting 120 million people into poverty and 40 million into abject poverty," the report said.

"India is headed towards a W-shaped economic recovery with a potential GDP contraction of 10.8 per cent in FY21. An opportunity loss of USD 1 trillion is staring India in its face," said Barnik Chitran Maitra, lead author of the report and Managing Partner & CEO of Arthur D Little, India and South Asia.

Maitra further said "for its USD 5 trillion vision, a radical economic approach is needed, centred on an immediate stimulus and structural reforms. The Prime Minister's visionary 'Atma Nirbhar Bharat Abhiyan' is a good start to this new approach."

The report lauded the steps taken by the government and the Reserve Bank of India, but said a far more assertive approach may be required given the magnitude of the adverse economic output.

The report suggested a 10-point programme to accelerate the recovery which include strengthening the 'safety net' significantly for the most vulnerable, enable survival of small and medium businesses, restarting the rural economy and providing targeted assistance to at-risk sectors.

It further said the government should launch "Make in India 2.0" to capture global opportunities, build 'Modern India', accelerate Digital India and Innovation, strengthen global investment corridors with the US, UAE, Saudi Arabia, Japan and the UK, debottleneck land and labour and transform banking and financial markets in a bid to secure a sustainable economic future for 1.3 billion Indians.

New Delhi, Mar 9: The Delhi Police Special Cell on Monday arrested a PFI member Danish from UP''s Moradabad for allegedly spreading fake propaganda during anti- CAA protests.

"Danish was the head of the Counter Intelligence Wing of PFI and has been actively participating in the anti-CAA protest across the city," sources in the Delhi Police Special Cell said.

Sources further claimed that his arrest has given clues regarding the Information war by the Popular Front of India (PFI).

The FIR related to the protest was filed by the Crime Branch but since the larger conspiracy regarding the Delhi riots is being probed by the Cell, the matter has been transferred to them.

Delhi Police Special Cell had on Sunday arrested a Kashmiri couple from Okhla for alleged links with Islamic State (IS) Khorasan module.

The couple have been identified as Jahanjeb Sami (husband) and Hinda Bashir Beg (wife). The police have seized some objectionable material from them and were interrogating them.

When asked about the couple, the sources said, "Officers of CERT-In are analysing the Eight Mobile phones and Laptop of the couple to question them further."

The couple being an active member of ISJ&K was operating from the Valley but later shifted their base to Delhi post internet clampdown.
