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.

Perfluorooctane Sulfonate Induces Apoptosis in N9 Microglial Cell Line

International Journal of Toxicology, 2010
Perfluorooctane sulfonate (PFOS) is an environmental persistent acid found at low levels in human, wildlife, and environmental media samples. To study the apoptosis effects of PFOS on microglia, murine N9 cell line was used as a model in current research.

Partitioning Characteristics of Perfluorooctane Sulfonate Between Water and Foods

Archives of Environmental Contamination and Toxicology, 2011
As a persistent, bioaccumulative, and toxic organic pollutant, perfluorooctane sulfonate (PFOS) has been found ubiquitously in the environment, including in tap water. For the first time, we studied PFOS sorption from water to foods (nine commonly consumed vegetables, three meats, and cereals) at two temperatures to estimate the daily intake of PFOS ...

Perfluorooctane sulfonate impairs rat Leydig cell development during puberty

Chemosphere, 2018
Perfluorooctane sulfonate (PFOS) possibly delays male sexual development. However, its effects on pubertal Leydig cell development are unclear. The objective of the present study was to investigate the effects of in vivo PFOS exposure on rat Leydig cell development during puberty.

Photodegradation of perfluorooctane sulfonate in environmental matrices

Separation and Purification Technology, 2015
Abstract Effective photodegradation of perfluorooctane sulfonate (PFOS), an environmentally-ubiquitous persistent organic pollutant, in simple aqueous solution has been previously demonstrated. However, photocatalyst usually needs to be added and its application in complicated aquatic environment has not been reported so far.
