About Per- and Polyfluoroalkyl Substances

  • These are toxic, man-made, hazardous chemicals. 
  • These are also known as the Forever Chemicals, are a large chemical family of over 4,700
  • They are a large family of fluorinated chemicals that have partially or completely fluorinated carbon chains of varied lengths. 
  • Because the carbon-fluorine bond is one of the strongest, these chemicals do not degrade easily in the environment.
  • Subgroups: Perfluorooctane sulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA), and persistent organic pollutants (POPs).
  • These subgroups are currently listed under the Stockholm Convention as industrial POPs.
  • How Are People Exposed to PFAS?
    • They are ingredients in various everyday products. For example, PFAS are used to keep food from sticking to packaging or cookware, make clothes and carpets resistant to stains
    • PFAS are used in the aerospace, automotive, construction, and electronics industries. Over time, PFAS may leak into the soil, water, and air.
    • People are most likely exposed to these chemicals by consuming PFAS-contaminated water or food, using products made with PFAS, or breathing air containing PFAS. 
  • Impacts of PFAS on Human Health: Decreased fertility, developmental effects in children, interference with body hormones, increased cholesterol levels, and increased risk of some cancers.
  • Regulation: The Stockholm Convention has listed some PFAS, such as Perfluorooctane sulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA), as persistent organic pollutants (POPs).
