The term "forever chemicals" has been used to describe polyfluorinated organic molecules that are prone to bioaccumulation and highly resistant to breakdown by ordinary environmental mechanisms. The older term "persistent organic pollutants," [1] as codified in the Stockholm Convention on Persistent Organic Pollutants, is a broader way of referring to the same concept.

The Materials Project is for inorganic crystals. The project will not unleash new forever chemicals because it doesn't deal with organic molecules.
