What's the deal with PFAS, a.k.a. 'forever chemicals'?

Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," are synthetic compounds known for their resistance to heat, water, and oil, making them prevalent in various consumer products and industrial applications. However, studies indicate that PFAS exposure is linked to serious health risks, including decreased immunity, certain cancers, birth defects, and liver and kidney diseases. These chemicals persist in the environment and human bodies for extended periods, raising significant health concerns. The Environmental Protection Agency (EPA) has recently set new limits on PFAS levels in drinking water, mandating monitoring by 2027.

Research has shown that PFAS can accumulate in water, soil, and wildlife, with evidence suggesting that exposure can lead to adverse health outcomes. Major retailers are beginning to phase out PFAS, but many products still contain these chemicals, leaving consumers uncertain about their safety. Experts emphasize the need for more comprehensive regulations and research to understand the full impact of PFAS on health, particularly as many of the thousands of PFAS compounds remain unstudied.

Individuals can take steps to reduce their exposure, such as using non-PFAS cookware and filtering drinking water. However, experts agree that significant reductions in exposure will require broader regulatory changes. The consensus is that PFAS represent a widespread public health concern, necessitating informed consumer choices and advocacy for stronger chemical regulations.
