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.

HP5 Specific Target Organ Toxicity (STOT)/Aspiration Toxicity: waste which can cause specific target organ toxicity either from a single or repeated exposure, or which cause acute toxic effects following aspiration. Corrigendum to “Renal function and isomers of perfluorooctanoate (PFOA) and perfluorooctanesulfonate (PFOS): Isomers of C8 health project in China” (Chemosphere (2019) 218 (1042–1049), (S0045653518322987) (10.1016/j.chemosphere.2018.11.191)) Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is an anthropogenic fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009.

Technical Fact Sheet – PFOS and PFOA PFOS and PFOA can also be formed by environmental degradation or by metabolism in larger organisms from a large group of related perfluorooctanesulfonate. 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.

Perfluorooctanesulfonate (PFOS) is a widespread contaminant in the environment, as well as in wildlife and in humans. Toxicity tests in rodents have raised concerns about potential developmental, reproductive, and systemic effects of PFOS.

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.

Abstract Perfluorooctanesulfonate (PFOS) is a persistent pollutant that can induce toxic effects, including leukemia, on blood cells. Concerns about the neurotoxic potential of polyfluoroalkyl substances (PFAS) such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) increase, although their neurotoxic mechanisms of action remain debated. Considering the importance of the GABA_A receptor in neuronal function, we investigated acute effects of PFAS on this receptor and on spontaneous neuronal Perfluorooctanesulfonate (PFOS) is an environmental toxicant used in developing countries, including China, as a stain repellent for clothing, carpets and draperies, but it has been banned in the Background: Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) persist in the environment and are found in relatively high concentrations in animal livers.

Perfluorooctanesulfonate or perfluorooctanesulfonic acid (PFOS) and its related products such as perfluorooctanoate (PFOA) were first produced by 3M in 1949 as fluorosurfactants, serving as a fabric protector (such as a key ingredient in Scotchgard) and an active component in stain repellents by lowering surface tension of water.

Previous studies have examined associations between PFASs and renal function, yet the results are mixed.

Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) are man-made compounds with widespread presence in human sera. In previous occupational and adult studies, PFOA and PFOS were

Nevertheless, little is known of the potential for PFOS biodegradation, even though the importance of characterizing the function and activity of microbial populations detected in the environment has been discussed.

PFOS (perfluorooctanesulfonate) in serum is negatively associated with testosterone levels, but not with semen quality, in healthy men.
