What are perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS) and other perfluoroalkyl substances (PFASs)?
Source: The United States Environmental Protection Agency
Per- and polyfluoroalkyl substances (together, PFASs) are a class of man-made chemicals. They are not found naturally in the environment. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body.
What are PFASs used for?
PFASs have been widely used to make products more stain-resistant, waterproof and/or nonstick. For example, PFASs have been used in the manufacture of products that:
- keep food from sticking to cookware,
- make upholstered furniture, carpets and clothing resistant to soil, stains and water,
- make shoes, clothes and mattresses more waterproof,
- keep food packaging from sticking to food, and
- help fight fires at airfields and other places where petroleum-product-based fires are a risk.
How widespread are these chemicals in the environment?
PFOA, PFOS and other PFASs are widespread around the globe, primarily due to their current and/or historical manufacturing, processing and use here in the U.S. and internationally. They are widespread in part because they are persistent in the environment – that is, they do not break down when exposed to air, water or sunlight. As a result, people may become exposed to PFASs manufactured months or years in the past.'
Due to their persistence, PFASs can travel long distances through the air; monitoring in the Arctic has shown levels of PFASs in air, water, and living things. As a result, people may become exposed to low levels of PFASs manufactured or emitted from production facilities thousands of miles away.
Because these chemicals have been used in an array of consumer products, most people have been exposed to low levels of them. Studies have found PFOS and PFOA in blood samples of humans and wildlife nationwide.
