PFAS chemicals are a class of chemicals used to make products grease proof, water-proof, stick-proof, and stain-resistant. They are added to:
- Food Packaging: pizza boxes, food wrappers, take out containers, microwave popcorn bags, disposable trays, and bakery bags;
- Non-stick pans (Teflon)
- Firefighting foam
- Carpets, rugs, furniture textiles, window treatments, car seats
- Stain-proof and waterproof clothing
- Outdoor gear
- Personal care products like dental floss, mascara, foundation, menstrual underwear
- Artificial turf
- Medical equipment and masks
- Building products
- Firefighters’ personal protective equipment,
- And more.
PFAS chemicals have been dubbed “forever chemicals”, because they are extremely persistent, lasting thousands of years. Every American tested has PFAS in their blood.
That’s a problem because very small doses of PFAS increase the risk of a wide variety of health problems, including kidney and testicular cancer, liver problems, high cholesterol, and immunosuppression.
In 2005, under pressure from a class action lawsuit, industry stopped manufacturing two of the most harmful PFAS chemicals: PFOA and PFOS. But, these two chemicals have contaminated water systems across the country, and the world.
Industry has replaced PFOA and PFOS with similar, but slightly modified chemicals. While scientists have not studied every PFAS chemical—there are 9,000 variants—those chemicals that have been studied show similar properties to PFOA and PFOS. They are persistent, mobile and toxic at very low doses, often acting in similar ways on similar organs as the chemicals they were developed to replace.
