How to pronounce
PFAS

PFAS (short for Per- and polyfluoroalkyl Substances) are a large group of highly durable chemicals with water- and grease-resistant properties. They are widely used in the manufacture of many everyday products.

PFAS break down extremely slowly and can build up in the environment and in the human body, even at low levels of exposure. Because of their exceptional persistence, they are often referred to as “forever chemicals.”

PFAS can affect the immune system and lipid metabolism, damage the liver and thyroid, and have harmful effects on fertility, pregnancy, and human development. Some PFAS compounds are also carcinogenic.

They are used in waterproof fabrics, sportswear, non-stick cookware, shampoos, feminine hygiene products, cosmetics, furniture, carpets, paper, food packaging, and pesticides. They are even used in catheters, hospitals, to make them more flexible.

In contaminated areas, PFAS can seep into the soil, groundwater, and drinking water, eventually entering the food chain. They are commonly found in fish, shellfish, eggs, and other animal products.

The correct pronunciation of PFAS is PEE-fuss.
