PFOS is a perfluoralkyl sulfonate that is commonly used as a simple salt (such as potassium, sodium or ammonium) or is incorporated into larger polymers (EFSA 2008; EPA 2009c). PFOA is a perfluoralkyl carboxylate that is produced synthetically as a salt Ammonium salt is the most widely produced form (EFSA 2008; EPA 2009c).

In our studies, as observed under the transmission electron microscope, PFOS increased autophagosome numbers in HepG2 cells. It was confirmed by elevated LC3-II levels in Western blot analysis. Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are fluorinated hydrocarbons used as water-, oil-, and stain-resistant coatings in fabrics, leather, and carpets, and oil-resistant coatings for paper products for food contact, and also as photographic emulsifier, aviation … Wilkins, P (2001a) Perfluorooctanesulfonate, potassium salt (PFOS): An acute oral toxicity study with the honey bee. Study number HT5602.
The potassium salt of PFOS has a measured vapour pressure of 3,31 x 10-4 Pa. ( OECD, 2002). Due to this vapour pressure and a low air-water partition coefficient
Perfluorooctane sulfonate (PFOS) and its salts are perfluorinated organic compounds with surfactant properties. Common salts of PFOS include the ammonium, diethanolamine, potassium, and lithium forms. PFOS can be released from several fluorochemicals, such as perfluorooctane sulfonamide The physical and chemical properties of the potassium salt of PFOS are listed in Table 2. Table 2. Physical and chemical properties of PFOS potassium salt.

CAS Number: 2795-39-3. EINECS: 220-527-1. Perfluorooctane sulfonate (PFOS) and its salts are fully fluorinated organic compounds. The number of production sites is not clear, but there is production in the US, Europe and Japan. In recent years (to 2000), approximately 4,500 metric tons of PFOS-related chemicals have been produced annually.
