Sufficient information exists to address hazard classification for all SIDS human health endpoints. for example the potassium salt of PFOS has a solubility in fresh water of 370 mg/L and of 25 mg/l in filtered sea water. Chemical Name: Perfluorooctane Sulfonate Synonym: PFOS CAS: 1763-23-1 (acid) 29081-56-9 (ammonium salt) 70225-14-8 (diethanolamine salt) 2795-39-3 (potassium salt) 29457-72-5 (lithium salt) Serum concentrations appear to be the best dose-metric for extrapolating to humans. At the present »> 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. Perfluorooctane sulfonate (PFOS) is a perfluoroalkyl acid (PFAA) and a persistent environmental contaminant found in the tissues of humans and wildlife.

It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009.[1] PFOS can form from the degradation of precursors in addition to industrial production. 2016-12-08 2015-03-23 Sorption and desorption of perfluorooctane sulfonate (PFOS) on humic acid at different temperatures were studied.
Perfluorooctane sulfonate (PFOS) is a perfluoroalkyl acid (PFAA) and a persistent environmental contaminant found in the tissues of humans and wildlife. (potassium salt) in 0.5% Tween 20. Five biological replicates consisting of individual animals were included in each dosage group.
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. (Data from OECD, 2002, unless otherwise noted).
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).

PFOA is a perfluoralkyl carboxylate that is produced synthetically as a salt Ammonium salt is the most widely produced form (EFSA 2008; EPA 2009c). 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.
