The first study to quantify the environmental burdens of 'forever chemicals' has found it is likely the future impact has been underestimated.
Per-and poly-fluoroalkyl substances, commonly referred to as PFAS, are man-made chemicals heavily used since the 1940s for their resistance to heat, water, grease and stains.
They are found in everyday appliances from non-stick pans to clothing, insecticides, food packaging and firefighting foam and once in the environment they don't degrade further.
