#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."

Toxic air pollution here and there
After weeks of spraying pesticides, then burning the logged plantations, the smoke lingered in a smoulderscape that left soot on all objects and ln lungs. Now the rain washes the cocktail of herbicides together with the ultrafine particle smoke into the surrounding soil and waterways. Negative externalities caused by the NSW government's Forestry Corporation. >>

Pulverising oil wells into our atmosphere"Reports are emerging of black rain falling over parts of Iran in the hours after US-Israeli airstrikes on oil depots on the weekend, with some outlets describing it as “acid rain”. Iranian residents have reported headaches, difficulty breathing, and oil-contaminated rain settling on buildings and cars."
"This rain would include acids but also likely a host of other pollutants that are harmful to humans and the environment in the short and long term.This black rain indicates toxic pollutants such as hydrocarbons, ultrafine particles known as PM2.5, and carcinogenic compounds called polycyclic aromatic hydrocarbons (PAHs) have made their way into the rain. When ultrafine particles (PM2.5) are inhaled, they can get into your bloodstream. This has been linked to a range of health impacts including cancers, neurological conditions (such as cognitive impairment), and various cardiovascular conditions." >>
