Perfluorinated alkylated substances
Perfluorinated alkylated substances (PFAS) refers to a group of fluorinated carbon-chain chemicals. PFAS include perfluorinated carboxylic acids but also similar sulfonic acids and sulfonates.
Examples
- perfluorooctanoic acid (PFOA)
- perfluorooctane sulfonate (PFOS)
- perfluorohexane sulfonic acid (PFHxS)
- perfluorononanoic acid (PFNA)
- perfluorodecanoic acid (PFDA)
Usage
These substances are used in consumer products and industrial applications because of their water-, grease-, and stain-resistant properties.[1] Some of these substances have been linked to significant reproductive problems.[1]
