In this eye-opening episode of Learn Something, we explore the science, scope, and serious health concerns surrounding PFAS — commonly known as “forever chemicals.” These synthetic compounds, found in everything from nonstick cookware and waterproof clothing to fast food packaging and firefighting foam, are making headlines for a reason: they don’t break down easily, they accumulate in the environment and our bodies, and they’re everywhere.

We break down what PFAS actually are — a massive family of over 4,000 manmade chemicals with super-strong carbon-fluorine bonds — and why their water-, oil-, and stain-resistant properties made them attractive to over 200 industries. But those same properties also make PFAS incredibly persistent and nearly impossible to eliminate once released.

You’ll learn how PFAS enter our bodies through contaminated drinking water, food, dust, and direct product exposure — and how they bioaccumulate, even transferring from mother to baby. We also cover the alarming health risks, including thyroid and kidney dysfunction, weakened immune response, reproductive issues, and increased cancer risks.

The episode explores what individuals can do to limit exposure — from choosing PFAS-free cookware and products to using certified water filters — while emphasizing that meaningful change must come through regulation, corporate accountability, and scientific innovation. We also dive into the complexities of detection, cleanup, and the troubling trend of “regrettable substitution,” where harmful PFAS are swapped with equally risky alternatives.

Whether you’ve just heard of PFAS or have been following the headlines, this episode equips you with the knowledge to make safer choices and advocate for a cleaner, healthier future.
