Historiquement, l&#8217;industrie d\u00e9signait ces produits chimiques sous le terme de compos\u00e9s perfluor\u00e9s ou PFC. Cependant, cet acronyme faisant \u00e9galement r\u00e9f\u00e9rence aux carbones perfluor\u00e9s, il est tomb\u00e9 en d\u00e9su\u00e9tude en tant que terme pour les <strong>compos\u00e9s PFAS<\/strong>. Bien que le sulfonate de perfluorooctane (PFOS) et l&#8217;<strong>acide perfluorooctano\u00efque (PFOA)<\/strong> soient les formes les plus couramment \u00e9voqu\u00e9es, les <strong>PFAS<\/strong> constituent une classe extr\u00eamement vaste, englobant plusieurs milliers de vari\u00e9t\u00e9s.   <\/p><p>Alors, qu&#8217;ont en commun ces substances diverses ? Tous les <strong>compos\u00e9s PFAS<\/strong> contiennent une cha\u00eene d&#8217;atomes de carbone li\u00e9s \u00e0 des atomes de fluor, mais le nombre exact d&#8217;atomes varie selon le produit chimique sp\u00e9cifique. Dans les substances perfluoroalkyl\u00e9es par exemple, tous les carbones sauf le dernier de la cha\u00eene sont attach\u00e9s \u00e0 des atomes de fluor. Pour les <strong>substances polyfluoroalkyl\u00e9es<\/strong>, en revanche, au moins un (mais pas tous) des carbones de la cha\u00eene sont attach\u00e9s \u00e0 des atomes de fluor. Le nombre d&#8217;atomes de carbone contenus dans la cha\u00eene perfluor\u00e9e d&#8217;un compos\u00e9 le distingue comme \u00e9tant soit un <strong>PFAS \u00e0 longue cha\u00eene<\/strong> (sept atomes de carbone ou plus), soit un <strong>PFAS \u00e0 cha\u00eene courte<\/strong> (moins de sept atomes).[1]    <\/p><p>Une autre caract\u00e9ristique cl\u00e9 des <strong>PFAS<\/strong> est qu&#8217;il s&#8217;agit de compos\u00e9s fluor\u00e9s <em>synth\u00e9tiques<\/em> qui ne se trouvent pas naturellement dans l&#8217;environnement.
