PARIS — They didn't exist a century ago, but today,"forever chemicals" contaminate the environment from groundwater to Antarctic snow to turtle eggs, and concern over their possible toxicity is growing.PARIS — They didn't exist a century ago, but today,"forever chemicals" contaminate the environment from groundwater to Antarctic snow to turtle eggs, and concern over their possible toxicity is growing.
Widely used in everyday items, highly durable, and very slow to break down, PFAS have been detected in water, air, fish and soil in the remotest corners of the globe. A study published in January by the American Chemical Society, a nonprofit scientific organisation, said that PFAS had been detected in the Arctic Ocean at a depth of 3,000 feet .
A 2022 study in Australia established the transmission of PFAS from female turtles to their unborn offspring, while other research found traces in polar bear livers and birds, seals and other animals. It is a subject of growing concern, with French ecologist and MP Nicolas Thierry asking lawmakers to ban PFAS from 2025 if alternatives exist.
