PFAS part one: What are PFAS and how are they impacting marine ecosystems?

Updated: Jul 19, 2021

Many commercial and industrial products depend on synthetic compounds for their unique chemical properties. One widely used class of waterproof and fat-repellent compounds, known as per-and polyfluoroalkyl substances (PFAS), can be found in everything from non-stick coatings for cookware to fire-extinguishing foam. While they were first developed in the 1930s, the National Institute of Environmental Health Sciences estimates that over 4,700 PFAS exist today.
