The stock solution of PFOA was prepared in deionized water (100 mg L −1 ), and the PFOS stock solution (20 mg mL −1 ) was prepared in dimethylformamide (DMF) and diluted 100 X in distilled water to achieve 200 mg L −1 . The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Salts of perfluorooctanoic acid, in particular ammonium perfluorooctanoate (APFO), have been used as surfactants and processing aids in the production of fluoropolymers and fluoro-elastomers. Industrial production of the salts of perfluorooctanoic acid occur through electrochemical fluorination and telomerization. 99% Ammonium perfluorooctanesulfonate;CAS:29081-56-9 29081-56-9 Suppliers,provide 99% Ammonium perfluorooctanesulfonate;CAS:29081-56-9 29081-56-9 product and the products related with China (Mainland) 99% Ammonium perfluorooctanesulfonate;CAS:29081-56-9 29081-56-9 Changchun Artel lmport and Export trade company China (Mainland) perfluorooctanesulfonate.

Ammonium Heptadecafluoro-1-octanesulfonate Perfluorooctanesulfonate (PFOS) is a fully fluorinated eight-carbon anion, which is commonly used as a salt or incorporated into larger polymers. The majority of PFOS-related substances are polymers of high molecular weights in which PFOS is only a fraction of the polymer (OECD, 2002). given the ammonium salt of PFOA by oral gavage from gestational day (GD) 1 to 17 at doses of 0, 1, 3, 5, 10, 20 or 40 mg/kg/day. Significant increase in the incidence of full-litter resorption occurred at 5 mg/kg/day and higher doses. Weight gain in dams that carried pregnancy to term was significantly lower in the 20-mg/kg/day group.
