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.

Perfluorooctane sulfonate acute exposure stimulates insulin secretion via GPR40 pathway

Science of The Total Environment, 2020
Perfluoroalkyl substances (PFASs) are widely used synthetic chemicals, showing environmental/biological persistence and adverse effects on ecosystem and human health. Several epidemiological and animal studies have revealed that PFASs levels are associated with elevated serum insulin level; however, the effect of PFASs on insulin secretion and the ...

Partitioning of perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS) and perfluorooctane sulfonamide (PFOSA) between water and sediment

Chemosphere, 2011
Laboratory partitioning experiments were conducted to elucidate the sorption behaviour and partitioning of perfluoroalkyl compounds (PFCs). Three different sediment types were used and separately spiked with perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS) and perfluorooctane sulfonamide (PFOSA) at low environmentally realistic ...

Adsorption of perfluorooctane sulfonate on carbonized poly-melamine-formaldehyde sponge

Science of The Total Environment, 2020
In this study, we developed a simple carbonized poly-melamine-formaldehyde sponge (CMF) acting as an adsorbent for adsorbing perfluorooctane sulfonate (PFOS) from the waste poly-melamine-formaldehyde (MF) sponge. The PFOS removal by the developed adsorbent was comprehensively investigated using batch adsorption, including kinetics, isotherm, ionic ...

Oxidative Damage and Cytotoxicity of Perfluorooctane Sulfonate on Chlorella vulgaris

Bulletin of Environmental Contamination and Toxicology, 2016
We studied the effects of perfluorooctane sulfonate (PFOS) on the chlorophyll content, cell permeability, and antioxidant defense systems of the green alga Chlorella vulgaris. The results showed that the production of reactive oxygen species increased in a concentration-dependent manner after exposure to PFOS for 96 h. Superoxide dismutase and catalase

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) contamination from textiles

Journal of Environmental Science and Health, Part A, 2016
The goals of this study were to determine the concentrations of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in textiles and to determine PFOS and PFOA contamination in textile washing water. Quantification analysis was performed by high performance liquid chromatography coupled with tandem mass spectrometry.

Perfluorooctane sulfonate-induced changes in fetal rat liver gene expression

Toxicology, 2008
In utero exposure of laboratory rats to perfluorooctane sulfonate (PFOS, C(8)F(17)SO(3)(-)), a chemically stable surfactant that is widely disseminated in the environment and present in serum samples from wildlife and humans, is associated with decreased neonatal survival, and growth deficits as well as hepatomegaly.
