Understanding PFAS: Industrial Applications and Environmental Impact

Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals known for their exceptional resistance to heat, water, and grease. This unique resilience comes from strong carbon-fluorine bonds, which make PFAS ideal for industrial and consumer applications. However, their durability also contributes to their nickname, “forever chemicals,” due to their persistence in the environment. Learn more about PFAS and their properties.

Industrial Applications of PFAS

PFAS chemicals have been widely used across several industries because of their performance-enhancing properties. Key applications include:

  • Metal Finishing and Plating:
    PFAS have been used in plating processes to reduce air emissions of chromium and ensure uniform coating.

  • Semiconductor Manufacturing:
    PFAS are critical in producing semiconductors, where they enable precision in photolithography and etching processes. 

  • Textile and Upholstery Treatments:
    PFAS provide water and stain resistance, enhancing the durability of fabrics. Discover how PFAS improve textiles.

  • Firefighting Foams:
    Aqueous film-forming foams (AFFFs) containing PFAS are commonly used to extinguish high-intensity liquid fires.

Environmental and Health Concerns

Despite their utility, PFAS are under scrutiny because of their environmental persistence. PFAS do not break down easily, accumulating in soil, water, and living organisms.

Potential Health Impacts

Research indicates that exposure to certain PFAS chemicals may lead to various health risks, including:

  • Increased cholesterol levels
  • Impacts on liver function
  • Immune system dysregulation
  • Potential links to cancer

For more details on health concerns, see the Centers for Disease Control and Prevention’s (CDC) report on PFAS.

Phasing Out PFOS in Industry

One of the most widely studied PFAS chemicals, perfluorooctane sulfonic acid (PFOS), was historically used in various industrial applications, including the metal plating industry, where it was employed to suppress hexavalent chromium air emissions. Due to mounting concerns about its persistence in the environment and potential health risks, the primary manufacturer in the U.S. voluntarily phased out PFOS production by 2002. PFOS is no longer manufactured or actively used in the U.S., although it may still be found in the environment from historical use. Learn more about PFOS regulation.

Regulatory Efforts and Industry Solutions

Governments worldwide are taking steps to regulate PFAS and minimize their environmental impact. These include stricter emissions controls, the development of safer alternatives, and the remediation of contaminated sites. Stay updated on PFAS regulations from the EPA.

Industries are also actively pursuing solutions to reduce PFAS use. For example, alternatives to PFAS-based firefighting foams and greener surface finishing processes are being developed.
