PM didn't question Manmohan Singh, Ansari's commitment to nation: Jaitley

New Delhi, Jul 18: The Covid-19 lockdown-led reduction in air pollution levels across five Indian cities, including Delhi and Mumbai, may have prevented about 630 premature deaths, and saved USD 690 million in health costs in the country, according to a new study.

Scientists, including those from the University of Surrey in the UK, assessed the levels of harmful fine particulate matter (PM2.5) from vehicles and other sources in five Indian cities -- Delhi, Mumbai, Kolkata, Chennai and Hyderabad -- since the beginning of the lockdown period.

The study, published in the journal Sustainable Cities and Society, compared these lockdown PM2.5 figures from 25 March up until 11 May, with those from similar periods of the preceding five years, and found that the measure reduced pollution levels in all these places.

According to the scientists, during this period, the levels of these harmful air pollutants reduced by 10 per cent in Mumbai, and by up to 54 per cent in Delhi.

"The percentage reduction for the other cities ranged from 24 to 32 per cent, which was slightly smaller than the measured values for Delhi and Mumbai," the scientists noted in the study.

"While the reduction in PM2.5 pollution may not be surprising, the size of the reduction should make us all take notice of the impact we have been having on the planet," said Prashant Kumar, a co-author of the study from the University of Surrey.

The scientists said these reductions in PM2.5 were comparable to those reported in other cities across the world, such as in Austria's capital Vienna (60 per cent), and Shanghai (42 per cent) in China.

They also calculated the monetary value of the reduced mortality due to air pollution and found that the lowered levels of PM2.5 may have saved 630 people from premature death, and USD 690 million in health costs in India.

According to the researchers, the present lockdown situation offers observational opportunities regarding potential control systems and regulations for improved urban air quality.

They said an integrated approach might help in understanding the overall impacts of Covid-19 lockdown-style interventions and support the implementation of relevant policy frameworks.

"This is an opportunity for us all to discuss and debate what the 'new normal' should look like - particularly when it comes to the quality of the air we breathe," Kumar said.

New Delhi, Jun 23: The Delhi High Court Tuesday granted bail to Jamia student Safoora Zargar, who is pregnant and was arrested under anti-terror law UAPA in a case related to communal violence in northeast Delhi during protests against the Citizenship Amendment Act, as Solicitor General Tushar Mehta did not oppose it on humanitarian grounds.

At the outset of the hearing, Mehta, representing Delhi Police, submitted that Zargar can be released on regular bail on humanitarian grounds and the decision has not been taken on merits of the case and should not be made a precedent.

Justice Rajiv Shakdher, who conducted the hearing through video conferencing, released Zargar, who is 23-week pregnant, on bail on furnishing a personal bond of Rs 10,000 and surety of like amount.

The court said she shall not indulge in any activity for which she has been charged with and shall not hamper the investigation or influence the witnesses.

New Delhi, Mar 3: Delhi's Tihar Prison authorities had made all necessary preparations for the hanging of four convicts in the Nirbhaya gangrape-and-murder case which was scheduled for Tuesday, officials said Monday.

However, on Monday evening, a city court deferred the hanging till further orders.

Postponing the execution, Additional Sessions Judge Dharmender Rana said the hanging cannot be carried out pending disposal of Pawan Gupta's mercy plea before the President, observing any condemned convict must not meet his "Creator" with grievance against courts for not acting fairly on the opportunity to exhaust legal remedies.

"We had made all the necessary arrangements for the execution of the four convicts which was scheduled for Tuesday at 6 AM. Now, the execution has been postponed and we are waiting for the further order by the court," a senior jail official said.

The hanging of the four men -- Mukesh Kumar Singh (32), Vinay Kumar Sharma (26), Akshay Kumar Singh (31) and Pawan -- who are lodged in Tihar jail, was fixed for March 3 in Tihar jail on a court order.

"We had checked the ropes. Hangman was called and dummy executions were carried out," another senior jail official said.

Barring Pawan, the other three had in the previous weeks moved curative petitions and mercy pleas which were all dismissed.

The first date of execution -- January 22 -- fixed on January 7 was postponed by the court to February 1. But on January 31, the court indefinitely postponed the hanging. On February 17, the court again issued fresh date for execution of death warrants for March 3 at 6 AM.

The court in its orders observed that the four convicts cannot be hanged since a mercy plea of one or the other convict was pending.
