PFCs are man-made chemicals commonly found in non-stick pan coatings as well as in some carpets, soft-furnishings, and clothing. PFCs have been around for a while, and so have concerns about their toxicity. Sure, they’re great for water-resistance and stopping your eggs sticking to the pan, but once they get into the environment they break down very slowly and can stick around for years to come. PFCs have adverse effects on the health of those wearing these garments (or using certain non-stick cookware), and also impact wildlife downstream. PFCs have been seen to cause harm to reproductive health and to promote tumor growth and are on the globally-recognized Restricted Substances Lists. Find out more about PFCs here.
