    Ocean spray emits more PFAS than industrial polluters

    "Stockholm researchers several years ago found that PFAS from ocean waves crashing are released into the air around shorelines, then can travel thousands of kilometers through the atmosphere before the chemicals return to land."

    “We thought PFAS were going to go into the ocean and would disappear, but they cycle around and come back to land, and this could continue for a long time into the future."

    The #alga #Melosiraarctica, which grows under #ArcticSea ice, contains ten times as many #microplastic particles as the surrounding #seawater. This concentration at the base of the #foodweb poses a threat to creatures that feed on the algae at the sea surface. Clumps of #deadalgae also transport the #plastic with its #pollutants particularly quickly into the #dee sea & explains high #microplastic #concentrations in the #sediment there. phys.org/news/2023-04-arctic-i
