PFAS (per- and poly- fluorinated alkyl substances) comprise a group of over 5,000 chemicals, many of which are toxic to humans and wildlife and last so long in the environment they have been referred to as ‘forever chemicals’. PFAS are used in numerous consumer products to confer waterproof, greaseproof, stain-proof and non-stick properties. They are also used for industrial purposes such as fire fighting foam. It is now becoming clear that PFAS are in the food, water, air, and bodies of many people around the world. The few PFAS that have been thoroughly studied show adverse impacts on the endocrine, immune, and metabolic systems.
