Perfluorooctane Sulfonate Concentrations in Surface Water in Japan

Archives of Environmental Contamination and Toxicology, 2003
Perfluorooctane sulfonate (PFOS) is a class of specialty chemicals used in a variety of applications, and has been found to be globally distributed in many living organisms including humans. Several analytical methods have been developed for determination of PFOS in environmental samples and biological matrices.

Sorption of perfluorooctane sulfonate (PFOS) on marine sediments

Marine Pollution Bulletin, 2012
Sorption of anionic perfluorooctane sulfonate (PFOS) on marine sediment was investigated in detail. It was found that solution ionic composition and sediment-specific parameters played important roles in affecting the sorption of PFOS. The results indicated that sorption of PFOS in seawater to marine sediments was strong (≈ 10 times higher than that in

Effects of perfluorobutane sulfonate and perfluorooctane sulfonate on lipid homeostasis in mouse liver

Environmental Pollution, 2022
Perfluorobutane sulfonate (PFBS), an alternative to perfluorooctane sulfonate (PFOS), has been increasingly used in recent years. However, emerging evidence has raised concerns about the potential health risks of PFBS. Here, the toxicityof low-dose PFBS on livers was explored and compared with that of PFOS.

Sonochemical Decomposition of Perfluorooctane Sulfonate and Perfluorooctanoic Acid

Environmental Science & Technology, 2005
Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are shown to be globally distributed, environmentally persistent, and bioaccumulative. Although the toxicities of these compounds were reported, the cleanup procedure from the environment is not developed because of their inertness.

Technical-grade perfluorooctane sulfonate alters the expression of more transcripts in cultured chicken embryonic hepatocytes than linear perfluorooctane sulfonate

Environmental Toxicology and Chemistry, 2011
Abstract Recently it was discovered that the perfluorooctane sulfonate (PFOS) detected in wildlife, such as fish-eating birds, had a greater proportion of linear PFOS (L-PFOS) than the manufactured technical product (T-PFOS), which contains linear and branched isomers.

Perfluorooctane sulfonate induces neuronal vulnerability by decreasing GluR2 expression

Archives of Toxicology, 2016
Perfluorooctane sulfonate (PFOS) is a persistent environmental contaminant. Although studies have described PFOS-induced neurotoxicity in animal brains and neuronal cells, the molecular mechanisms of PFOS-induced neurotoxicity based on the distribution properties, especially during developmental periods, have not been clarified.

Sorption of perfluorooctane sulfonate and perfluorooctanoate on activated sludge

Chemosphere, 2010
Perfluorinated compounds (PFCs) as one class of emerging pollutants have caused great attention in recent years. In this study, activated sludge was used to adsorb perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in aqueous solution in order to investigate their sorption behavior and possible uptake mechanism in wastewater treatment ...

Can Bees Detect Perfluorooctane Sulfonate (PFOS)?

Environmental Toxicology and Chemistry
Abstract The European honey bee (Apis mellifera) is an important crop pollinator threatened by multiple stressors, including exposure to contaminants. Perfluorooctane sulfonate (PFOS) is a persistent global contaminant that accumulates and biomagnifies in food chains and is detected in honey.

Perfluorooctane sulfonate (PFOS) induced embryotoxicity and disruption of cardiogenesis

Toxicology in Vitro, 2013
Prenatal exposure to perfluorooctane sulfonate (PFOS) is correlated with birth defects and adverse health effects. However, the mechanisms remain largely unknown. In current study, the embryonic stem cell test (EST) was performed to evaluate the embryotoxicity of PFOS, and embryonic stem cells (ESCs)-derived cardiomyocytes were used as a model of the ...

Thyroid disruption by perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA)

Journal of Endocrinological Investigation, 2016
Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are two fluorinated compounds widely used in industry because of their useful chemical characteristics. They were identified as endocrine disruptors due to their ability to interfere with thyroid function.
