"Eternal" toxic chemicals move in the waters of the Arctic - scientists

12 january 2024

American and German oceanologists have discovered the movement of "eternal" toxic substances in the Fram Strait between the Atlantic and Arctic Oceans.

Analysis of water samples showed the content of at least ten different per- and polyfluorinated alkyl substances, some of them are present at a depth of more than a kilometer.

Every year, about 123 tons of "eternal" toxic chemicals enter the northern waters from the Atlantic Ocean, and about 110 tons move in the opposite direction during the same time.

"Eternal" chemicals accumulate in humans and animals and can cause various diseases, including cancer. Chemicals are used in the manufacture of goods to impart fat- and water-repellent properties, ttelegraf.ru writes.
