Ces liaisons chimiques stables en font des compos\u00e9s chimiques tr\u00e8s peu d\u00e9gradables. C\u2019est la raison pour laquelle on les surnomme parfois les \u00ab\u00a0produits chimiques \u00e9ternels\u00a0\u00bb. \n<br \/>\nParmi les substances PFAS les plus connues et les plus persistantes dans l\u2019environnement figurent le PFOS et le PFOA, aujourd\u2019hui interdites.
