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.

Bengaluru: Karnataka has declared a holiday for state government offices, schools and colleges on Wednesday, December 11, in the wake of a state funeral for former chief minister S M Krishna, who passed away in Bengaluru on Tuesday.

The last rites of Krishna, 92, will be held at his native village of Somanahalli in Mandya's Maddur taluk.

A government order stated that the holiday would apply to private aided educational institutions too.

Besides, the government has declared three days of mourning (December 10-12), during which no public entertainment programmes would take place, while the national flag would fly at half-mast.

S M Krishna passed away at his residence on December 10, 2024. The 92-year-old veteran politician was ailing for quite some time, a family source said.

A charismatic leader with a modern outlook, he not only laid a strong foundation for the growth of IT and BT industries in Karnataka but also managed to get them onboard with the government to build “Brand Bengaluru” at the international level.

He held several prominent positions throughout his career as External Affairs Minister, Maharashtra Governor, Chief Minister of Karnataka, Speaker of Karnataka Legislative Assembly and Minister in the Karnataka government.

Although known for his tech savviness, flamboyancy, style and the Western outlook, the Congressman-turned-BJP senior leader was a hardcore Bengalorean who loved the city’s trees and flowers. SMK also had a love for tennis. Even when he was Chief Minister, he would visit the tennis court to play the game two to three times a week.

Angry BJP lawmakers stormed Assembly Speaker U T Khader’s chambers at the Suvarna Vidhana Soudha, escalating tensions after the ruling Congress turned the tables on the saffron party over the Panchamasali Lingayat community’s reservation issue.

The friction began when Congress MLA Vijayanand Kashappanavar, a Panchamasali Lingayat, was allowed to criticise the Basavaraj Bommai-led BJP government’s controversial decision to scrap the 4 per cent Muslim quota, reallocating it equally to Lingayats and Vokkaligas. Kashappanavar slammed the BJP’s move, accusing it of being a mere election gimmick.

“The previous BJP government created two new reservation categories, 2C for Vokkaligas and 2D for Lingayats, just before the 2023 Assembly elections,” Kashappanavar said. “When challenged in the Supreme Court, the BJP government admitted it would not implement the decision. They announced it for votes but backtracked in court, misleading Panchamasali seer Basava Jaya Mrityunjaya Swami.”

Adding fuel to the fire, Kashappanavar alleged that RSS members had incited violence during a protest for enhanced Panchamasali Lingayat reservation. This claim enraged BJP lawmakers, who demanded the comment be expunged. However, Speaker Khader permitted Revenue Minister Krishna Byre Gowda to read aloud the BJP government’s affidavit to the Supreme Court.

“If the Panchamasali Lingayat community has faced injustice, it is because of the BJP,” Gowda declared, sparking further protests from the opposition. BJP leaders accused Khader of being “one-sided” and disregarding a point of order raised by BJP MLA V Sunil Kumar.

When Khader adjourned the session for lunch, the confrontation boiled over. Opposition Leader R Ashoka, BJP state president B Y Vijayendra, MLAs Dr C N Ashwath Narayan, Sunil Kumar, and others barged into Khader’s chambers. Chaos ensued as shouting and hollering echoed through the halls, prompting marshalls to intervene.

“The Speaker was warned that if he continued behaving this way, we would boycott the session,” Narayan stated afterward.

Dhaka: Bangladesh's interim government said on Monday that it has sent a diplomatic note to India to send back deposed prime minister Sheikh Hasina to Dhaka.

Hasina, 77, has been living in exile in India since Aug 5 when she fled the country amid the student-led protests that toppled her 16-year regime. Dhaka-based International Crimes Tribunal (ICT) has issued arrest warrants for Hasina and several former Cabinet ministers, advisers, and military and civil officials for "crimes against humanity and genocide".

“We have sent a note verbale (diplomatic message) to the Indian government saying that Bangladesh wants her back here for the judicial process,” Foreign Affairs Adviser or de facto foreign minister Touhid Hossain told reporters at his office.

Earlier in the morning, Home Advisor Jahangir Alam said his office has sent a letter to the foreign ministry to facilitate the ousted premier's extradition from India.

“We have sent a letter to the foreign ministry regarding her extradition. The process is currently underway,” he told reporters in response to a query.

Alam said an extradition treaty between Dhaka and New Delhi already exists and Hasina could be brought back to Bangladesh under the treaty.
