I skipped rally because I was misled: Anna Hazare

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, Jan 7: When a reign of terror was unleashed by "masked goons" in the Jawaharlal Nehru University (JNU) on Sunday, Delhi Police registered two cases against varsity students union president Aishe Ghosh, who was badly injured in the attack, within a span of five minutes.

The registration of cases on two separate complaints against Ghosh and other students filed by JNU security department on January 3 and January 4 were registered on Sunday night when the violence was on, triggering questions about the motive behind the timing.

While the FIRs against Ghosh and others were registered between 8.44 pm and 8.49 pm after the JNUSU president was admitted to AIIMS, an FIR on the Sunday violence was registered on Monday at 5.36 am against unknown persons. The Sunday violence case has been transferred to Crime Branch for further investigations.

Questions are being raised over the registration of FIRs on Sunday while the complaints were filed on the previous days. Students allege that it was an afterthought from the police and authorities, as a nationwide outrage erupted as soon as the violence was reported.

Delhi Police is under attack for not coming to the aid of students targeted by the mob of ABVP activists armed with iron rods and sticks who went on a rampage on the campus. While no single person in the Sunday violence was arrested, the police are also accused of being a "mute spectator" by allowing the rioters to leave the campus without being arrested.

In its complaints, the JNU Security Department has alleged that Ghosh and others entered into a verbal and physical scuffle with security guards, including women, when officials tried to open the Centre for Information System (CIS) that was blocked by students protesting against the fee hike and registration process.

While the January 3 complaint claims that the students switched off the power supply to the CIS and evicted staff forcefully, the January 4 complaint alleged that they damaged the information system.

They also claimed the students damaged the servers, made it dysfunctional, severely damaged optic fibre cables and broke the biometric system in the CIS. The complaint also cited a Supreme Court order that prevented any protest within 100 metres of Administration Block and claimed the students violated the direction.

The FIR filed on Sunday violence on the basis of the statement of Inspector Anand Yadav said that the first phase of violence was reported at 3.45 pm when "40-50 unidentified" people who had "covered their faces" attacked students in Periyar Hostel and the situation was brought under control.

However at around 7 pm, "50-60 people with rods in their hands" targeted students in Sabarmati Hostel in which students were attacked and public property destroyed.

The FIR said that students were injured but skipped the mention of the attack on teachers, who were injured. At least two faculty members Sucharita Sen and Ameet Parameswaran were taken to AIIMS while several other teachers suffered minor injuries.
