Per- or polyfluorochemicals, known as PFCs, are a family of chemicals that are widely used to make water-, grease- and stain-repellent coatings. They’re also used in myriad consumer goods and industrial applications.
These chemicals are notoriously persistent in the environment and the human body, and some have been linked to serious health effects.
For ways to avoid these harmful chemicals, check out EWG’s Guide to Avoiding PFCs.
