Learn More About the Global Pollutants PFOA & PFOS

PFAS are not known to break down in the environment and have become global pollutants that threaten the health of people and wildlife. Once in our bodies, they stick around - with half-lives in people of up to eight years.



WHAT ARE PFAS?

  • PFAS are a large group of man-made chemicals that have been used since the 1950s.
  • Use of these chemicals have decreased in the United States in the last 10 years.
  • People can still be exposed to pFAS because they are still present in the environment.
  • PFAS do no break down easily in the environment.
  • PFAS builds up in bodies of exposed humans and animals.

WHAT PRODUCTS CONTAIN PFAS?

  • Non-stick cookware
  • Outdoor gear with "durable water repellent" coating
  • Food packaging, such as microwave popcorn bags and fast food wrappers
  • Stain-resistant carpets, rugs and furniture
  • Firefighting foams, ski wax and industrial applications

HOW ARE YOU EXPOSED

WATER SYSTEMS: May have PFAS levels in your water systems, drinking water wells, soil and outdoor air near industrial areas with frequent PFAS used.

SURFACE WATER: Surface water (lakes, ponds, rivers, etc.) and run-off from areas where aqueous (water-based) film-forming fire fighting foam (AFFF) was often used (like military or civilian airfields).

FISH & CROPS: Can build up in crops, fish and livestock contaminating the food we eat. For example locally caught fish from contaminated bodies of water.

PACKAGING: Food packaging such as sandwich wrappers, takeout containers, fast food wrappers, microwave popcorn bags, pizza boxes and candy wrappers.

AIR & DUST: Stain proofing furniture and carpets release chemicals over time into air and dust.


PRODUCTS: In cleaners, personal care products, specialty products such a ski wax, grease-resistant paper, nonstick cookware such as Teflon coated pots and pans, stain resistant coatings such as scotch guard used on carpets, water resistant clothing, cleaning products, personal care products (shampoo, dental floss, cosmetics), paints, sealants, etc. 

WORKERS:  Workers may b expose dot PFAS by inhaling them, getting them on their skin, and swallowing them, but inhaling them is the most likely route of exposure. 


WHAT ARE THE HEALTH CONCERNS?


CANCER:  PFAS induce tumors in laboratory animals, and International Agency for Research on Cancer has designated PFOS as a possible carcinogen based on epidemiological evidence linking exposure to kidney and testicular cancer. 

IMMUNE SYSTEM: Studies show that the immune system is sensitive to PFAS. 

HORMONE DISRUPTION: Tests indicate that PFAS affects hormone production and response, with effects on estrogen production and response, thyroid hormone signaling, and regulation of fat metabolism. People exposed to higher levels of PFAS have higher total and LDL cholesterol. 

REPRODUCTIVE: Laboratory tests associated PFAS exposure with deceased survival of young, disrupted reproductive cycles, and impaired growth of the uterus and ovaries.

DEVELOPMENTAL: Epidemiological studies have related higher maternal exposure to PFCs to lower birth weight. 

LIVER & KIDNEY: PFAS are associated with multiple effects on liver and kidney, including liver lesions, kidney degeneration, and damage to liver function. 

Nearly every U.S. resident has PFAS in his or her body. 


HOW TO REDUCE EXPOSURE TO PFAS INGREDIENTS?


PERSONAL-CARE PRODUCTS:  PFCs can be found in dental floss and a variety of cosmetics, including nail polish, facial moisturizers, and eye make-up. Choose personal care products without "PTFE" or "FLUORO" ingredients. One simple way to identify these potentially harmful ingredients is to look at your product labels for the term “fluoro,” which may appear in a longer name, such as perfluorononyl dimethicone or perfluorodecalin. CLICK HERE to see some of the surprising cosmetics that contain PFAS ingredients: PTFE (Teflon), Perfluorononyl Dimethicone, Perfluorodecalin, C9-15, Fluoroalcohol Phosphate, Octafluoropentyl Methacrylate, Perfluorohexane, Pentafluoropropane, Polyperfluoroethoxymethoxy Difluoroethyl Peg Phosphate, Polyperfluoroethoxymethoxy Peg-2 Phosphate, Methyl Perfluorobutyl Ether, Perfluorononylethyl Carboxydecyl Peg-10 Dimethicone, Perfluorodimethylcyclohexane, Perfluoroperhydrophenanthrene. 


TEFLON: Avoid Teflon, non-stick cookware, PTFE-based nonstick pans and kitchen utensils. Opt for cast iron instead.


STAIN-RESISTANCE: Be wary of all fabrics labeled stain or water repellent. Choose furniture and carpets that aren't marketed as "stain-resistant," and don't apply finishing treatments to these items. Choose alternatives to clothing the has been treated for water resistance, such as outerwear, shoes, luggage or camping equipment. 


WRAPPERS:  Cut back on fast food and greasy carryout food. These foods often come in PFAS treated wrappers. 


POPCORN BAGS and pop popcorn the old-fashioned way, on the stovetop. Microwaveable popcorn bags are often coated with PFAS chemicals on the inside. 

EATING FISH from bodies of water with high PFAS levels. 

INGESTION OF WATER if your water contains PFAS by using an alternative or treated water source for drinking, food preparation, cooking and brushing teeth.

Toxicological Profile for Perfluoroalkyls: Agency for Toxic Substance and Disease Registry
June 20th toxicological profile drops the level of exposure to people into the single digit parts-per-trillion (ppt) range.
