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.

Prime Minister Narendra Modi Tuesday condoled the death of environmentalist Tulsi Gowda and said she will remain a guiding light for environmental conservation.

In a post on X, he said, "Deeply saddened by the passing of Tulsi Gowda Ji, a revered environmentalist from Karnataka and Padma Awardee. She dedicated her life to nurturing nature, planting thousands of saplings, and conserving our environment."

"She will remain a guiding light for environmental conservation. Her work will continue to inspire generations to protect our planet. Condolences to her family and admirers. Om Shanti," he added.

Tulsi Gowda, the renowned environmentalist and Padma Shri awardee known as the "Vruksha Maate" (Mother of Trees), passed away on Monday at her residence in Karnataka’s Honnali village, Ankola Taluk, Uttara Kannada district. She was 86 and had been suffering from age-related ailments.

Hailing from the Halakki tribal community, Tulsi Gowda dedicated over six decades of her life to environmental conservation, planting and nurturing thousands of trees in Ankola and its surroundings.

Her unparalleled knowledge of plants earned her the title "Encyclopaedia of Plants." She was credited with growing lakhs of saplings and was celebrated for her unique approach to nurturing them, ensuring their survival and growth.

Born in 1944 to a tribal family, Tulsi Gowda developed a deep connection with nature at a young age. She began working at a forest department nursery as a daily wage worker and eventually became a symbol of afforestation.

In 2021, Tulsi Gowda was honored with the prestigious Padma Shri, one of India’s highest civilian awards, in recognition of her immense contributions to afforestation and environmental conservation.

She received the award from former President Ram Nath Kovind, a moment that brought her years of silent work into the national spotlight. Additionally, Dharwad Agricultural University conferred upon her an honorary doctorate for her knowledge and contributions to the environment. She also received the Indira Priyadarshini Vriksha Mitra award and numerous other accolades throughout her lifetime.

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.
