The Risks of PFAS

The Risks of PFAS

Per- and polyfluoroalkyl substances (PFASs) are a class of man-made chemicals used in the production of a wide range of consumer products such as stain resistant carpets, non-stick pans, waterproof jackets, and grease-proof food packaging. These chemicals are extremely persistent, and some can linger in our bodies for many years. Nearly all Americans carry traces of these chemicals in our bodies.

With over 4,000 PFASs on the global market, these toxic chemicals pose an enormous public health challenge. PFASs have been linked to a wide range of health effects including immune system toxicity, elevated cholesterol, delayed mammary gland development, effects on the thyroid and liver, and cancer. Scientists are concerned that exposures to chemicals that alter mammary gland development may increase the risk of breast cancer later in life.

PFASs are also showing up in a growing number of drinking water supplies across the U.S. Often this contamination is linked to the use of firefighting foams commonly used at military bases, airports, and fire training areas. Some contamination comes from industrial sources.
