PFOS (perfluorooctanesulfonate, or perfluorooctane sulfonic acid) is an anthropogenic fluorosurfactant widely used in consumer products. While its use in Europe, Canada and the U.S. has been banned due to its human toxicity, it continues to be used in China and other developing countries as a global pollutant. Herein, using an in vitro model of Sertoli cell blood-testis barrier (BTB), PFOS was

Environmental toxicants such as perfluorooctanesulfonate (PFOS) have been implicated in male reproductive dysfunction, including reduced sperm count and semen quality, in humans. However, the underlying mechanism(s) remains unknown. Herein PFOS …

Int Arch Occup Environ Health . 80:643-648. Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) November 2017 . Introduction This fact sheet, developed by the U.S. Environmental Protection Agency (EPA) Federal Facilities Restoration and Reuse Office (FFRRO), provides a summary of two contaminants of emerging concern, perfluorooctane Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant (POP) and emergent contaminant that are widespread in the environment. Understanding the mechanisms controlling the distribution of PFOS and its isomers between hydrargillite and the water phase is important in order to study their redistribution and mobility in the environment.

Perfluorooctanesulfonate function

The decision followed the announcement by a major US manufacturer (3M) to globally phase out 2007-10-26 · Thyroid hormone status and pituitary function in adult rats given oral doses of perfluorooctanesulfonate (PFOS). Shu-Ching Chang Medical Department, 3M Company, St. Paul, MN 55144, United States. PFOS (perfluorooctanesulfonate, or perfluorooctane sulfonic acid) is an anthropogenic fluorosurfactant widely used in consumer products. While its use in Europe, Canada and the U.S. has been banned due to its human toxicity, it continues to be used in China and other developing countries as a global pollutant. Herein, using an in vitro model of Sertoli cell blood-testis barrier (BTB), PFOS was A paucity of data exists to corroborate the few studies that report immune suppression after exposure to perfluorooctanesulfonate (PFOS). In this study, adult male C57BL/6 mice were exposed to PFOS daily via gavage for 60 days [0, 0.5, 5, 25, 50, or 125 mg/kg total administered dose (TAD)].

For PFOS-related substances, x = 7. Dec 8, 2016 Strengths of this study include identifying a beneficial role for PFOS as a chemo- preventive or therapy in a familial model of colorectal cancer, Perfluorooctane sulfonate Fluoro-organic chemicals such as perfluoro-octane sulfonate (C8F17SO3H)(PFOS), have been used since the 1950s in soil- and PFOA and PFOS are abbreviations for the chemicals “perfluorooctanoic acid” ( PFOA) and “perfluorooctanesulfonic acid” (PFOS).

Perfluorooctanesulfonate is one of the nine new persistent organic pollutants (POPs) listed under Annex B of the Stockholm Convention on Persistent Organic Pollutants in 2009. Perfluorooctanesulfonate has been reported to have an effect on animal hepatic and reproductive functions [5, 9].

Molecular Formula C 8 F 17 O 3 S; Average mass 499.122 Da; Monoisotopic mass 498.930206 Da; ChemSpider ID 2966466 In conclusion, branched PFOS isomers were negatively associated with renal function whereas their linear counterparts were not. Given widespread exposure to PFASs, potential nephrotoxic effects are of great public health concern, Furthermore, longitudinal research on the potential nephrotoxic effects of PFASs isomers will be necessary to more definitively assess the risk. Perfluoroalkyls are stable, synthetic chemicals. Perfluoroalkyls are unique because they repel oil, grease, and water.The two perfluoroalkyls made in the largest amounts in the U.S. are perflurooctanoic acid and perfluorooctane sulfonic acid (PFOS).Perfluoroalkyls have been used in surface protection products such as carpet and clothing treatments and coating for paper and cardboard packaging.

Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) are perfluoroalkyl acids: man-made compounds used as emulsifiers during the manufacture of fluoropolymers, which are chemicals that give nonstick heat resistance to cookware or breathable yet waterproof properties to fabrics and upholstery. Introduction: Perfluorooctanesulfonate (PFOS) is widely distributed and persistent in humans and wildlife. Prior toxicological studies have reported decreased total and free thyroid hormones in serum without a major compensatory rise in thyrotropin (TSH) or altered thyroid gland histology.

However, the molecular mechanisms underlying the neurotoxicity of PFOS remain largely unknown.

Prior toxicological studies have reported decreased total and free thyroid hormones in serum without a major compensatory rise in thyrotropin (TSH) or altered thyroid gland histology. Although these animals (rats, mice and monkeys) might have maintained an euthyroid state, the basis for Perfluorooctanesulfonate [PFOS; CF 3 (CF 2) 7 SO 3 −] and its acid salts were derived from perfluorooctanesulfonyl fluoride [POSF; CF 3 (CF 2) 7 SO 2 F]. Major product applications were developed using POSF through formation of N-alkylsulfonamides that were used in surfactants, paper and packaging treatments, and surface protectants (e.g., carpet, upholstery, textiles). Sigma-Aldrich offers abstracts and full-text articles by [Hin-Ting Wan, Dolores D Mruk, Chris K C Wong, C Yan Cheng].

Perfluorooctanesulfonate (PFOS) is a persistent pollutant that can induce toxic effects, including leukemia, on blood cells. Vitamin C (VC), a functional nutrient, has been found to possess potent cytoprotective effects. However, there are currently no reports on its ability to treat PFOS-associated leukemia. Perfluoroalkyls are stable, synthetic chemicals.
