#Algal #Toxins emerge as a new concern in #Alaska’s Northern Bering Sea
Locals who depend on the sea for food and culture are trying to understand the risks to traditional foods and wildlife populations in a region undergoing myriad changes
by Yereth Rosen, Alaska Beacon, May 31, 2026 via #ICTNews
Excerpt: "For countless generations, people of the #BeringStrait region have relied on the food they harvest from the sea without worrying about #HarmfulAlgalBlooms [#HABs] that threaten seafood eaters in warmer and more southern latitudes.
"Now, as the Northern Bering Sea undergoes cascading effects of a warming climate, algal risks pose a new challenge.
"The change has been dramatic.
"And it has prompted a change in the way #Nome youth grow up learning about collecting food from the waters around their home. In early April, Nome high school students traveled to Bethel with their science teacher, where they presented their research at the Western Alaska Interdisciplinary Science Conference held by Alaska Sea Grant.
"Algal toxins were present, at very low but detectable levels, in fish they eat.
"Sophomore Audrey Bruner-Alvanna was among the group of student researchers. She said young people are concerned about algal blooms, which proliferate in warmer conditions, and their potential effects on wild food resources.
" 'Because, you know, as the climate changes, as the world gets warmer and stuff, there’s going to be more of these toxins and stuff during summer,' she said. 'I feel like a lot of people that I’ve talked to have been wondering about how our subsistence is going to change in the future based on all of that.'
"The student research came about after one of the nation’s densest and biggest concentrations of toxin-producing Alexandrium algae ever documented burst forth in the waters of the Bering Strait region in 2022.
"Until the appearance of the 'massive bloom, the most toxic bloom, the longest-persisting bloom in the U.S.,' local people barely knew what harmful algal blooms or #Alexandrium are, said Emma Pate, president of the Nome Eskimo Community, the local tribal government.
" 'So we had to figure things out and learn really fast,' Pate said during an October 'Strait Science' presentation hosted by the University of Alaska Fairbanks’ Nome campus."

#Farmers allege link between popular #herbicide and #Parkinsons disease
November 29, 2023
"It is against the law to use #paraquat in China, Switzerland, the United Kingdom and dozens of other countries. Many countries have banned the herbicide due to its extreme #toxicity, while others have expressed concerns over the possible risk for Parkinson's disease.
"Yet the herbicide, manufactured by a #Swiss company that is owned by the #Chinese state, is still widely used throughout the #UnitedStates in part because it is a highly effective way to kill weeds.
"The company, Syngenta, says that paraquat, which it produces under the name Gramoxone, 'is safe for its intended and labelled use.'
"Clayton Tucholke, who used Gramoxone for years on his farm in LaBolt, #SouthDakota, and has since been diagnosed with Parkinson's disease, says otherwise.
"'It should have been pulled, I think, you know, so it didn't happen to somebody else,' Tucholke told ABC News.
"A 76-year-old father and grandfather, Tucholke lived on his farm with his wife Denise, but as the symptoms of #Parkinson's have worsened, he says he was forced to give up his career in #agriculture and had to move to the nearby town of Milbank to be closer to medical professionals.
"Daily tasks have become arduous for Tucholke, who now has to travel to physical therapy three times a week to slow the progression of his symptoms.
"'This man was so independent,' Denise Tucholke said. 'And his independence has been taken from him, which is unfair.'
"The Tucholkes are among the more than 4,000 Americans who have filed lawsuits as part of a multi-district litigation against #Syngenta, which currently manufactures #Gramoxone, and #Chevron, which distributed it in the U.S. from 1966 until 1986.
"Although Syngenta and Chevron told ABC News that there is no scientific evidence that supports a causal link between #paraquat and #Parkinsonsdisease, the Tucholkes and other plaintiffs allege that such a link exists, arguing that Syngenta and Chevron knew or should have known that the #herbicide could 'cause severe #neurological injuries.'
"'Our daughter and son-in-law are still #farming. I think any time [a] chemical is applied to the fields that they have to use, they should know what's going to happen,' Denise Tucholke said.
"'All the generations that are coming up afterwards need to know,' she said."

A cocktail of toxins is poisoning our fields. Its effect on humans? Nobody can tell us
Many of the chemicals being spread as sewage sludge are untested or can’t be assessed. That’s why I’m suing for answers, says Guardian columnist George Monbiot
