Riskvärdering av perfluorerande alkylsyror i livsmedel - Studylib

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 Chemical name: Perfluorooctane Sulfonate (PFOS) Molecular formula: C8F17SO3 Structural formula: Figure 1. Structural formula of PFOS shown as its potassium salt Synonyms: 1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro; 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-1-octanesulfonic acid; It breaks down to form perfluorooctane sulfonate (PFOS). The perfluorooctanesulfonyl fluoride -based chemistry that was used to make sulfonamides like PFOSA was phased out by 3M in the United States (US) during 2000–2002 but it has grown in China by other producers.
