PFAS – What is it?

Which stands for Per- and Polyfluoroalkyl Substances, are a group of man-made chemicals that have gained significant attention and concern due to their widespread presence in the environment and potential health risks. These chemicals are characterized by the presence of fluorine-carbon bonds, which make them highly resistant to heat, water, and oil. PFAS are often used in a variety of industrial and consumer products because of these properties.

There are thousands of different PFAS compounds, but the two most well-known and extensively studied members of this group are perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). These substances have been used in the manufacturing of various products, including:

  • Non-stick cookware (Teflon coatings)
  • Water-resistant clothing
  • Firefighting foams (Aqueous Film-Forming Foams, or AFFF)
  • Stain-resistant coatings for carpets and upholstery
  • Food packaging materials
  • Electrical and electronic components
  • Some industrial processes

The widespread use and persistence of PFAS in the environment have raised concerns about their potential health effects. Studies have shown that exposure to certain PFAS compounds may be associated with various health problems, including:

  • Developmental and reproductive issues
  • Liver damage
  • Immune system suppression
  • Certain types of cancer
  • High cholesterol levels
  • Thyroid disruption

Due to these concerns, regulatory agencies and governments around the world have taken steps to regulate and reduce the use of PFAS. Many countries, including the United States, have established guidelines and regulations to limit the presence of certain PFAS compounds in drinking water and various products.

Efforts are also being made to remediate contaminated sites and find safer alternatives to PFAS in manufacturing and consumer products. The management and regulation of PFAS continue to be an active area of research and policy development to protect human health and the environment.
