High concentrations of ‘forever’ chemicals being released from ice melt into the Arctic Ocean

Known as ‘forever’ chemicals due to the fact they do not break down in the environment, poly- and perfluoroalkyl substances (PFAS) are used in a wide range of products and processes from fire proofing to stain resistant surfaces.

The Lancaster University study has found them in the surface seawater close to melting Arctic ice floes at concentrations of up to two times higher than levels observed in the North Sea, even though the region of the Barents Sea under investigation was thousands of kilometers from populated parts of Europe.

The research has shown these chemicals have traveled not by sea, but through the atmosphere, where they accumulate in Arctic sea ice. Because Arctic ice is melting more quickly than before, these harmful chemicals are efficiently released into surrounding seawater resulting in some very high concentrations. Read more…
