Happy that Defence Minister has accepted mistake: BJP

Tehran, May 17: As many as 310 Indian pilgrims departed from Tehran, Iran for New Delhi by Mahan Air on Saturday. The group hails from Ladakh and will later go home to Leh by special flights.

"A group of 310 Indian pilgrims, hailing from Ladakh, departed Tehran for New Delhi by Mahan Air tonight (16th May). 
Thereafter, they'll go home to Leh by special flights," Embassy of India in Iran wrote on Twitter.

On Saturday, Minister of Civil Aviation, Hardeep Singh Puri said that over 13,000 people have returned under the Vande Bharat repatriation mission till date.

"More than 13,000 people have already returned on various flights under Mission Vande Bharat so far. Today, 812 citizens have returned on Air India and AirIndia Express flights from Newark, London, Dubai and Abu Dhabi. More flights continue," Puri wrote on Twitter.

Vande Bharat Mission, which started on May 7 to bring back stranded Indian nationals back home from other countries, initiated its second phase of the operation from Saturday (May 16) by sending three Air India flights to Dubai and Abu Dhabi.

Under the second phase of Vande Bharat Mission a total of 149 flights, including feeder flights, will be operated to bring back Indians from 40 countries. 

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

New Delhi, May 15: Union Health Minister Harsh Vardhan has appealed to all states and Union Territories to ban the sale of smokeless tobacco products and spitting in public places in line with the orders of the Rajasthan and Jharkhand governments to prevent the spread of coronavirus infection.

In a letter to all state health ministers, Vardhan said smokeless tobacco users have a tendency to spit in public places or otherwise and therefore, increase health risks especially those of spreading contagious diseases like COVID-19, tuberculosis, swine flu, encephalitis and others.

"Use of smokeless tobacco also creates an unhygienic environment which further spreads the diseases. The large gathering at the retail outlets where smokeless tobacco products are sold, also pose the risk of spread of COVID-19," he said.

In the letter dated May 11, the Union minister underlined that tobacco use is a major threat to public health globally. He also mentioned the Indian Council of Medical Research's (ICMR) appeal to the public not to consume and spit smokeless tobacco products in public places.

Chewing tobacco products and areca nut increases the production of saliva followed by a very strong urge to spit. Spitting in public places could enhance the spread of the COVID-19, Vardhan said.

"By banning spitting in public places, states and UTs can help in achieving not only Swachh Bharat but also Swasth Bharat (Clean India and Healthy India)," he said.

Vardhan also mentioned the May 1 guidelines issued by the Union Home Ministry under the National Disaster Management Act, 2005, which stipulate that "spitting in public places shall be punishable with fine as may be prescribed by the state/UT local authority and consumption of liquor, pan, gutkha, tobacco etc in public places is not allowed".

Appreciating the efforts of Rajasthan and Jharkhand in this direction, the Union Health Minister urged all states to take similar measures and create widespread awareness regarding the harm of spitting in public places.

The Rajasthan government had by an ordinance banned spinning in public places and sale of paan, gutka and tobacco in the wake of the coronavirus outbreak. The Jharkhand too has imposed a complete ban on all types of tobacco products to prevent spitting in public places that could increase the spread of coronavirus infection.

"I am happy to note that the governments of Jharkhand and Rajasthan have already completely banned the sale of tobacco products and spitting in public places. Therefore, I urge upon you to take similar measures and also create widespread awareness in your state/ UT regarding harms of spitting in public places.

"It is also requested that the directions of Ministry of Home Affairs in this regard may be implemented scrupulously and effectively," Vardhan said in the letter.

Tobacco smoking is a known risk factor for many respiratory infections and increases the severity of related diseases. A review of studies by public health experts convened by WHO on April 29 found that smokers are more likely to develop severe diseases, compared to non-smokers, said Binoy Mathew, senior programme officer of Voluntary Health Association of India.

It is one of the main risk factors for a number of chronic ailments, including cancer, lung and cardiovascular diseases, he said, adding that according to the Global Adult Tobacco Survey, with 268 million or 28.6 per cent of all adults in India, the country has the second largest number of tobacco users in the world.

At least 12 lakh die from tobacco-related diseases every year, Mathew said.

Those keen to quit smoking and smokeless products can avail of free of charge telephone-based services launched by the government. The Ministry of Health has set up a National Tobacco Quit Line Services to provide counselling services to help tobacco consumers quit the habit.
