What are the most common PFAS?

Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have been manufactured the longest, are the most widespread in the environment, and are the most well-studied. PFOS and PFOA, which are called long-chain PFAS, are no longer manufactured in the United States.

What foods and drinks contain PFAS?

Potential Dietary Sources of PFAS

It is estimated that the most significant dietary source of PFAS is fish and shellfish. The FDA has been testing for PFAS in foods such as produce, meat, dairy, grain, carbonated water, non-carbonated bottled water, seafood and milk.

What are the names of PFAS?

The five PFAS additions include: hexafluoropropylene oxide dimer acid and its ammonium salt (HFPO-DA – sometimes referred to as GenX chemicals), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorohexanesulfonic acid (PFHxS).

What are PFAS present in?

PFAS are man-made chemicals that have been used in industry and consumer products worldwide since the 1940s. They have been used to make nonstick cookware, water-repellent clothing, stain resistant fabrics and carpets, some cosmetics, some firefighting foams, and products that resist grease, water, and oil.

How do you get rid of PFAS in your body?

Currently, there are no definitive medical procedures that can clear PFAS (per- and polyfluoroalkyl substances) from the body, according to the Secretary of the United States Navy. However, the best step you can take is to remove the source of the exposure from your environment.

Does bottled water have PFAS?

You might think that bottled water is safer than tap water, but recent studies have found that some brands of bottled water contain PFAS above safe levels. This article will discuss the prevalence of these compounds in bottled water and what you should do if it’s in your favorite brand.

How do I know if a product has PFAS?

PFAS chemicals are often listed on product labels, so you should be wary of any ingredient with “fluoro” in the name. Our Skin Deep database can also help you identify products that may contain PFASs. If your favorite brand uses PFAS chemicals in its products, urge it to stop.

Do Brita filters remove PFAS?

A new filter cartridge that is compatible with Brita pitchers can remove per- and polyfluoroalkyl substances (PFAS) from drinking water.

Where is PFAS most commonly found?

PFAS chemicals were widely used in firefighting foams on military bases, airports and firefighting training facilities. They are also found in landfills when products containing PFAS break down, and in fertilizer made from human waste or sewage. All these sources can contaminate nearby drinking water supplies.

Where are the highest concentrations of PFAS found?

Michigan has the highest levels of PFAS in the U.S. According to the American Red Cross, “the blood of the average American has 4,300 parts per trillion, or ppt, of PFOS and 1,100 ppt of PFOA.”

Is bottled water tested for PFAS?

Currently, there are no U.S. Food and Drug Administration (FDA) Standards of Quality (SOQs) or testing requirements for per- and polyfluoroalkyl substances (PFAS) in bottled water.

Does tuna have PFAS?

After limited seafood testing, the U.S. Food and Drug Administration has found the presence of PFAS chemicals at levels many times higher than the federal recommended limit in some smoked clams and tuna.

Do Brita filters remove PFAS?

A new filter cartridge that is compatible with Brita pitchers can remove per- and polyfluoroalkyl substances (PFAS) from drinking water.

How do I know if my drinking water has PFAS?

If you are concerned about PFAS in your drinking water, EPA recommends you contact your local water utility to learn more about your drinking water and to see whether they have monitoring data for PFAS or can provide any specific recommendations for your community.

Do any water filters remove PFAS?

Water filtration units that use granular activated carbon (GAC, also called charcoal filters) or reverse osmosis (RO) can both be effective in removing the PFAS compounds that commercial labs typically analyze.

Is bottled water free of PFAS?

“As this study has found, the majority of bottled water does not contain any per- and polyfluoroalkyl substances,” she says. Nevertheless, Culora says the IBWA supports a request made last month by a bipartisan group of lawmakers who called on the FDA to enact legally enforceable PFAS standards.

What does PFAS do to your body?

A growing body of science has found that there are potential adverse health impacts associated with PFAS exposure, including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression and cancer. These chemicals can easily migrate into the air, dust, food, soil and water.
