Toxic Forever Chemicals: Understanding PFAS and Protecting Our Health

Jeff St. Clair discusses forever chemicals, a term that may be familiar to you in this edition of Spot on Science. These man-made substances do not easily break down in the environment and have the potential to contaminate drinking water sources and build up in wildlife and humans around the world, posing risks to our health.

One common type of forever chemical is PFAS, which can be found in various products such as nonstick skillets, waterproof clothing, stain-resistant fabrics, fast food wrappers, and even certain types of dental floss. Some makeup products, particularly long-lasting and waterproof ones, may also contain PFAS. Research has indicated that elevated levels of PFAS in the body can lead to issues with the liver, kidneys, thyroid glands, and digestive system.

It is important to be aware of the presence of forever chemicals in everyday products and to make informed choices to minimize exposure to these substances. By understanding the potential risks associated with PFAS and other forever chemicals, we can take steps to protect our health and the environment.
