Congress attacks BJP over northeast 'immigrants', BJP withdraws word

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.

Amaravati, Mar 16: Andhra Pradesh Chief Minister YS Jagan Mohan Reddy said that paracetamol is the only medication for coronavirus.

He said that COVID-19 is lethal for those have comorbid conditions including blood pressure, asthma and kidney diseases.

"There is no need to get panic about Coronavirus. Its impact is majorly on senior citizens aged above 60 years. It is dangerous to those suffering from diabetes, blood pressure, asthma and kidney diseases. For others, it is not so much dangerous. And paracetamol is the only medication for coronavirus," Reddy said on Sunday while addressing a press conference on the postponing of the local body elections as coronavirus cases continue to rise.

"In case anybody coming from foreign countries is found suffering from cough, cold and fever, bleaching powder should be sprayed on their belongings and things they use. The government is creating awareness on such precautions," he added.

Reddy slammed the State Election Commissioner's decision of postponing the local body elections for six weeks and alleged that the SEC was acting at the behest of TDP chief N Chandrababu Naidu.

The opposition has targeted Reddy on his statement, saying the chief minister is behaving "ignorantly" and "irresponsibly" on the issue of coronavirus.

"While Telangana CM had changed his stand and closed shops and theatres in his state, Jagan Reddy is speaking as if there is no need for any panic. This CM is behaving ignorantly and irresponsibly," said Naidu.

Andhra Pradesh has reported one case of coronavirus. The total number of confirmed COVID-19 cases across India has risen to 110.

New Delhi, Mar 30: The number of COVID-19 cases climbed to 1,071 in India on Monday, while the death toll rose to 29, according to the Union Health Ministry.

The number of active COVID-19 cases stood at 942, while 99 people were either cured or discharged and one had migrated, the ministry stated.

In its updated data at 10.30 am, it said two fresh deaths were reported from Maharashtra.

Thus, Maharashtra has reported the maximum number of eight COVID-19 deaths so far, followed by Gujarat (5), Karnataka (3), Madhya Pradesh (2), Delhi (2) and Jammu and Kashmir (2).

Kerala, Telangana, Tamil Nadu, Bihar, West Bengal, Punjab and Himachal Pradesh have reported a death each.

The total number of 1,071 cases includes 49 foreigners.

The highest number of confirmed cases of the pandemic has been reported from Kerala (194) so far, followed by Maharashtra at 193.

The number of cases has gone up to 80 in Karnataka, while Uttar Pradesh has reported 75 cases.

The number of cases has risen to 69 in Telangana, 58 in Gujarat and 57 in Rajasthan.

Delhi has reported 53 cases, while in Tamil Nadu, the number of positive cases is 50.

Punjab has reported 38 cases, while 33 COVID-19 cases have been detected each in Haryana and Madhya Pradesh.

There are 31 cases of the contagion in Jammu and Kashmir, followed by Andhra Pradesh (19), West Bengal (19) and Ladakh (13).

Bihar has 11 cases, while nine cases have been reported from the Andaman and Nicobar Islands. Chandigarh has eight cases, while Chhattisgarh and Uttarakhand have reported seven cases each.

Goa has reported five coronavirus cases, while Himachal Pradesh and Odisha have reported three cases each. Puducherry, Mizoram and Manipur have reported a case each, the Health Ministry said.
