Perfluorooctanoic acid
Perfluorooctanoic acid (PFOA) (pronunciation: per-fluoro-octanoic acid) is a synthetic perfluorinated carboxylic acid and fluorosurfactant. It is one of the most prominent members of perfluoroalkyl substances (PFASs).
Etymology
The term "Perfluorooctanoic acid" is derived from its chemical structure. The prefix "perfluoro-" indicates that all hydrogen atoms in the octanoic acid molecule have been replaced by fluorine atoms.
Chemical Structure
Perfluorooctanoic acid is a long-chain molecule with eight carbon atoms (octanoic), fully substituted with fluorine atoms (perfluoro). Its chemical formula is C8HF15O2.
Uses
PFOA has been used in the manufacture of a wide variety of consumer goods, including non-stick cookware, water-repellent clothing, and stain-resistant fabrics and carpets. It is also used in fire-fighting foams and in a variety of industrial applications.
Health Effects
Exposure to PFOA has been associated with a number of adverse health effects, including high cholesterol, thyroid disease, testicular and kidney cancer, and pregnancy-induced hypertension.
Regulation
Due to its persistence in the environment and potential health risks, the use of PFOA has been phased out in many countries. However, it is still detected in the environment, wildlife, and humans worldwide.
