Jerusalem, Aug 25: Wastewater containing coronaviruses, such as the one behind the Covid-19 pandemic, may be a potential threat, according to a new review of studies that calls for additional filtration steps in sewage treatment plants to successfully remove viruses.

The research, published in the journal Nature Sustainability, by an international collaboration of 35 researchers, assessed recent studies on coronaviruses in wastewater.

According to the review research, conventional wastewater treatment provides only partial removal of coronaviruses, with safe disposal or reuse depending on the effectiveness of final disinfection.

"There is ample reason to be concerned about how long coronaviruses survive in wastewater and how it impacts natural water sources," said study lead author Edo Bar-Zeev from the Ben-Gurion University of the Negev (BGU) in Israel.

"Can wastewater contain enough coronaviruses to infect people? The simple truth is that we do not know enough and that needs to be rectified as soon as possible," Bar-Zeev said.

According to the scientists, sewage leaking into natural watercourses might lead to infection with the novel coronavirus SARS-CoV-2 via airborne spray.

They said treated wastewater used to fill recreational water facilities, like lakes and rivers, could also become sources of contagion, adding that fruits and vegetables irrigated with this water may also be an indirect infection route.

The scientists recommended immediate, new research to determine the level of potential infection, if any, and how long coronaviruses last in various bodies of water and spray.

"Wastewater treatment plants need to upgrade their treatment protocols and in the near future also advance toward tertiary treatment through micro- and ultra-filtration membranes, which successfully remove viruses," the scientists noted.

They added that wastewater can also be used to monitor or track Covid-19 outbreaks.

Using a new methodology, the researchers recently detected and traced the presence of the novel coronavirus, and calculated its concentration to pinpoint emerging Covid-19 hotspots.

In yet another setback to the Congress party amid the ongoing Lok Sabha elections, its candidate from Indore Akshay Kanti Bam withdrew his nomination on Monday, April 29, days before voting.

Interestingly, he had reached the Collector's office with BJP MLA Ramesh Mendola to withdraw his nomination. He also reportedly joined BJP. 

Senior BJP leader and state cabinet minister Kailash Vijayvargiya in a post on X said Bam was welcome to join the BJP.

"Congress Lok Sabha candidate from Indore Akshay Kanti Bam is welcome in the BJP under the leadership of Prime Minister Narendra Modi, party national president J P Nadda, Chief Minister Mohan Yadav and state president VD Sharma," he said in the post.

The Congress had fielded Bam against sitting BJP MP Shankar Lalwani from the Indore Lok Sabha seat, where polling will be held on May 13.

Bengaluru: JD(S) leader H D Kumaraswamy on Sunday said he would like to wait for the facts to come out of the investigation into an alleged sex scandal involving his nephew and Hassan MP Prajwal Revanna, but asserted that there is no question of forgiving anyone who has committed a crime as per law.

The former chief minister said he has nothing to do with Prajwal Revanna reportedly leaving the country, and it is the responsibility of the Special Investigation Team (SIT) to get him back if required.

The 33-year-old Prajwal Revanna is the son of former prime minister and JD(S) patriarch H D Deve Gowda's elder son H D Revanna, who is an MLA and former minister.

Some explicit video clips allegedly involving Prajwal Revanna had started making the rounds in Hassan in recent days.

Prajwal Revanna is the BJP-JD(S) alliance's candidate from Hassan, which went to polls on Friday.

Kumaraswamy said, "I have noticed that the chief minister has ordered an SIT probe. Whether it is me or Deve Gowda (his father), we have always conducted ourselves respectfully towards women and have responded positively when anyone came with any sufferings. We have tried to address them."

Speaking to reporters here, he said, "The Hassan related issue that started during elections, let the facts come out through a probe. Whoever it is, who has committed the mistake as per the law of the land...there is no question of forgiving anyone who has committed the mistake. So let the facts come out from the probe, after that I will react."

To a question on Prajwal Revanna going to a foreign country, Kumaraswamy said, "It is not related to me. SIT probe has been ordered, officials have been put to work. If he has gone to a foreign country, getting him back is their responsibility. What should I say, if I'm asked. They (SIT) will get him, don't worry."

Chief Minister Siddaramaiah announced the decision to constitute a SIT to probe the alleged sex scandal involving the MP.

Meanwhile, the police have information that Prajwal has left the country, according to a statement issued by the Chief Minister’s office.

"Prajwal Revanna’s explicit video clips are being circulated in Hassan and it appears prime facie that women were sexually assaulted,' the statement said, adding that the government decided to form an SIT based on a petition by the chief of the Karnataka State Commission for Women.

The Commission's chairperson Dr Nagalakshmi Chaudhary on Thursday wrote to Siddaramaiah and state police chief Alok Mohan, seeking a probe into the videos that are in circulation in Hassan.

Prajwal has through his election agent lodged a complaint with the authorities that the videos are "doctored" and being circulated to tarnish his image ahead of elections.

At least 900 protesters have been arrested since the launch of pro-Palestinian demonstrations on university campuses across the US, where students are raging against the Israeli regime’s US-backed genocidal war on Gaza.

The Washington Post reported the tally on Sunday, the 10th straight day of the protests that began after Columbia University set up an encampment to demand cessation of the war and press the school to divest from Israeli financial interests.

The crackdown then started when university authorities called in the police, a move that sparked more than 100 arrests on the university’s Manhattan campus.

Two other highlights in the crackdown saw police forces rounding up roughly the same number of people at New York University and Emerson College in Boston.

Protests have also erupted across numerous other seats of learning, including Brown University in Providence, Rhode Island, the University of Michigan in Ann Arbor, Massachusetts Institute of Technology in Cambridge, and California State Polytechnic in Humboldt.

The ensuing countrywide counter-campaign of suppression has seen law enforcement resorting to riot control methods against the protesters.

The methods have featured “the same tools and tactics” that were deployed to confront the thousands-strong protests that sparked across the country after a Minneapolis police officer killed George Floyd four years ago, the daily reported.

“At Emory University last week, Atlanta police said officers used ‘chemical irritants’ to clear an encampment, and a Georgia State Patrol officer was captured on video using a stun gun to subdue a man on the ground,” it said.

Academics have, meanwhile, been banding together throughout the US under the banner of Faculty and Staff for Justice in Palestine (FSJP).

Earlier in April, the FSJP’s Georgia chapter called on Morehouse College in Atlanta, which invited Joe Biden as its 2024 commencement speaker, to rescind its invitation as a means of objecting to the president’s role in enabling the Israeli genocide.

At Biden’s behest, the United States has been providing the Israeli war with unreserved military and intelligence support.

The US has also vetoed several United Nations Security Council resolutions calling for an immediate ceasefire in the brutal military onslaught that has so far claimed the lives of at least 34,454 Gazans, mostly women and children.
