Secrets of the Norwegian lake

Researchers discovered that a seemingly pristine reference lake in Norway is contaminated with per- and polyfluoroalkyl substances (PFAS) from a paper factory.

When a lake in Norway was unexpectedly found to be contaminated with PFAS, researchers went looking for the source of the chemical, and found a paper factory. PFAS, known for their use in nonstick cookware and fire-fighting foams, are also used in manufacturing as a coating for paper that needs to repel oils and fats, such as microwave popcorn bags and fast-food wrappers.

“But then they found that this lake was as contaminated as a lake located next to an airport, and nobody knew why.”
