Study flags chemical contamination risk to endangered Gangetic dolphins
A scientific study has revealed alarming levels of toxic chemicals in the Ganga river, threatening the health and survival of the endangered Gangetic dolphins. Published in the journal 'Heliyon', the study by the Wildlife Institute of India found that these freshwater mammals are being exposed to a hazardous cocktail of endocrine-disrupting chemicals (EDCs) through their diet. The researchers analysed the dietary exposure risks of 39 EDCs in fish species consumed by Gangetic dolphins. The findings indicate significant bioaccumulation of industrial pollutants such as di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DnBP) in the prey base of the dolphins. Residues of banned pesticides like DDT and Lindane (HCH) were also detected, pointing to poor enforcement of environmental regulations in the Ganga basin. The Gangetic dolphin population has declined by over 50 per cent since 1957, and their range has shrunk by nearly a quarter, despite being designated as India's national aquatic animal. With only five species of river dolphins left globally, all of them threatened, the study warned that India could risk a repeat of the Yangtze River tragedy, where a similar species went extinct due to unchecked human activities. The study attributes the contamination to several sources: runoff from agriculture, untreated industrial effluents from the textile sector, vehicular emissions, poor solid waste management, and rising tourism in ecologically sensitive areas. The effects of EDCs are particularly worrisome as they can disrupt hormonal systems and reproductive functions in mammals, and persist in the ecosystem for long periods. Although toxicity risk quotients based on standard values were found to be low, when analysed against the reference dose --? a more realistic measure of exposure risk --? the dolphins were at a high risk from seven key pollutants -- DEHP, DnBP, DDT, arsenic, mercury, cadmium, and polychlorinated biphenyls (PCBs). The study recommended the urgent inclusion of these chemicals in dolphin conservation-monitoring programmes and calls for a scientifically informed national framework to assess and regulate chemical contamination in river ecosystems. The Gangetic dolphin is protected under Schedule I of the Wildlife Protection Act, 1972, but the study stresses that protection on paper must translate into actionable policy and pollution control if the species is to survive. The research from last year was among several key documents unveiled on a new portal launched by the Ministry of Jal Shakti to promote access to ecological data and conservation insights.

Like the Yangtze dolphin, the Ganga's own could vanish next: Scientists reveal 39 toxins poisoning this endangered species
A recent scientific study has revealed dangerous levels of toxic chemicals in the Ganga river, putting the health and survival of the endangered Gangetic dolphins at serious risk. The study, published in the journal Heliyon by the Wildlife Institute of India , found that these freshwater dolphins are being exposed to harmful endocrine-disrupting chemicals (EDCs) through the fish they eat. Researchers examined 39 different EDCs found in fish species that are a part of the dolphins' diet. They discovered high amounts of industrial pollutants like di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DnBP) accumulating in these fish. They also detected banned pesticides such as DDT and Lindane, which shows that environmental laws are not being properly enforced in the Ganga basin. The Gangetic dolphin population has dropped by more than 50% since 1957, and their living area has shrunk by nearly 25%, even though they are India's national aquatic animal. There are only five species of river dolphins left worldwide, all of which face threats. The study warns that India could face a disaster similar to the extinction of the Yangtze River dolphin in China, caused by human activities. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like If You Eat Ginger Everyday for 1 Month This is What Happens Tips and Tricks Undo The pollution comes from many sources, including agricultural runoff, untreated industrial waste from textile factories, vehicle pollution, poor waste management, and increasing tourism in sensitive ecological areas. EDCs are especially dangerous because they interfere with the hormonal systems and reproductive health of mammals, and they remain in the environment for a long time. While the initial toxicity risk appeared low based on standard measures, a more detailed analysis showed the dolphins are at high risk from seven key pollutants: DEHP, DnBP, DDT, arsenic, mercury, cadmium, and polychlorinated biphenyls (PCBs). Live Events The study suggests urgently adding these chemicals to dolphin conservation monitoring programmes. It also calls for a national plan based on scientific research to monitor and control chemical pollution in rivers. Though the Gangetic dolphin is protected by law under Schedule I of the Wildlife Protection Act, 1972, the study stresses that legal protection must be backed by real action on pollution control to save this species. This research, completed last year, was shared on a new portal launched by the Ministry of Jal Shakti, which aims to provide easier access to ecological data and help conservation efforts.

New Delhi, May 17 (PTI) A scientific study has revealed alarming levels of toxic chemicals in the Ganga river, threatening the health and survival of the endangered Gangetic dolphins. The findings indicate significant bioaccumulation of industrial pollutants such as di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DnBP) in the prey base of the dolphins. Residues of banned pesticides like DDT and Lindane (γ-HCH) were also detected, pointing to poor enforcement of environmental regulations in the Ganga basin.

Innovative company announces revolutionary product that could help protect food supply: 'A transformative development'
Rice is a staple crop for over half of the world's population and is grown in over 100 countries, but bacterial leaf blight (BLB) is causing crop losses and driving the use of potentially dangerous pesticides. Ascribe Bioscience, a New York-based agricultural tech company, believes it can reduce the impacts of the disease with its new biopesticide: Phytalix. Jay Farmer, the company's CEO and founder, told Forbes that he believes the product is "a transformative development for farmers big and small." "Current chemical solutions used to manage these diseases are not meeting growers' needs," added Farmer. "They are harmful to the environment, expensive, and are losing their efficacy as pathogens develop resistance." BLB primarily affects rice crops in both temperate and tropical zones, although it's been particularly devastating to crops in tropical regions of Asia, where losses of up to 74% have been piling up, as a study in the journal Heliyon, shared by Science Direct, observed. India has been especially hard hit, with yield losses up to 80%, as the disease flourishes in its warm, humid climate. This threatens to disrupt the country's rice crop, which accounts for 27% of the world's supply, as Forbes explained. Trials of Phytalix conducted in the country resulted in an 83% reduction in BLB severity while outperforming traditional treatments by 20%, according to the publication. Rice yields saw a 30% increase in tests where BLB was particularly heavy and an overall boost of 13% across all the areas it was applied. The use of pesticides is estimated to have grown 20% over the last decade, according to the Institute for Functional Medicine, with some low-income countries seeing growth of up to 153%. Many of these are chemical pesticides that are associated with elevated cancer risks, among other dangers to human health. This has led to substantial growth in the global market for natural, non-chemical pesticides, which was said to be worth $226.3 billion in 2021, according to Acumen research. Its projections say it could hit $631.4 billion by 2030. Some farmers in parts of Asia have been using antibiotics on their crops in hopes of fighting the disease, but researchers are worried it may be fueling antibiotic resistance while using up the valuable medical resource.

Phytalix, however, is "derived from natural molecules sourced from the soil microbiome" as Forbes explained, which makes it sustainable for rice farmers big and small. Ascribe said that it actually helps to boost the plant's immune system and guards against major fungal pathogens, as well as bacterial and viral disease. Natural methods of pest control such as this could provide a safer way to protect global rice production, which Forbes suggested is projected to increase by 11.12% by 2030. Srinivas Veeranki, managing director of crop science service AgReveal, told the outlet that Phytalix could be "a major step forward for farmers and global food security, offering effective and long-lasting disease control while also making rice production more resilient to growing environmental and market challenges." Ascribe's product is currently pending review in Brazil and the U.S., as Forbes explained, with future plans for approval in key rice-producing countries across Asia.
