Study finds chemical pollution and climate warming harming Arctic ringed seals at molecular level
By
Tanya Brown
Summary
New research reveals that ringed seals in the Canadian Arctic are being harmed by chemical pollution accumulating in the Arctic food web, compounded by rapid climate-driven warming that is transforming their sea ice habitat. The study highlights how these pollutants affect seals at the molecular level, with implications for the broader Arctic ecosystem, including polar bears that prey on seals and Inuit communities that rely on them for nutrition and cultural continuity.

· 4 pulledRinged seals are among the most common marine mammals in the Canadian Arctic.
They strongly rely on sea ice as a habitat, breathing through holes they maintain in the frozen surface, giving birth in snow lairs and diving beneath the ice to hunt Arctic cod and small crustaceans.
They are also a key prey for polar bears and an integral part of Inuit culture, providing nutrition, cultural continuity and a generations-long connection to land and sea.
Our new study shows these seals are being affected by chemical pollution in the Arctic food web and rapid climate-driven warming that is transforming their sea ice habitat.
