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.

Chronic perfluorooctane sulfonate (PFOS) exposure induces hepatic steatosis in zebrafish

Aquatic Toxicology, 2016
Perfluorooctane sulfonate (PFOS), one persistent organic pollutant, has been widely detected in the environment, wildlife and human. Currently few studies have documented the effects of chronic PFOS exposure on lipid metabolism, especially in aquatic organisms.

Behavioral effects in adult mice exposed to perfluorooctane sulfonate (PFOS)

Toxicology, 2007
Nowadays, very little information concerning the effects on behavior in mammals of perfluorooctane sulfonate (PFOS), a widely distributed persistent environmental pollutant, is available. In the present study, we assessed the behavioral effects of PFOS on 3 months old mice after 1 month of exposure to this pollutant. Thirty adult mice were divided into

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) and calcium channel downstream signaling molecules

Toxicology Research, 2012
As a neurotoxic environmental contaminant, perfluorooctane sulfonate (PFOS) has made a great impact on brain tissue. Neurotoxicity studies have shown that PFOS can cause abnormally high levels of calcium concentration in the hippocampus, thus inhibiting the growth of synapses, elevating the glutamate level in the nervous system, influencing behavioural

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in sewage treatment plants

Water Research, 2009
In this study, the concentrations of PFOS and PFOA in the biological units of various full-scale municipal sewage treatment plants were measured. Samples of influent, primary effluent, aeration tank effluent, final effluent and grab samples of primary, activated, secondary and anaerobically digested sludge were collected by 5 sampling events over one ...

Evaluation of Cyto-genotoxicity of Perfluorooctane Sulfonate (PFOS) to Allium cepa

Environmental Toxicology and Chemistry, 2020
Abstract Per- and polyfluoroalkyl substances (PFAS) have emerged as contaminants of global concern. Among several PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are persistent and bioaccumulative compounds. We investigated the cyto-genotoxic potential of PFOS to Allium cepa root meristem cells. The A.

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 ...

Does perfluorooctane sulfonate (PFOS) act as chemosensitizer in zebrafish embryos?

Science of The Total Environment, 2016
Earlier studies have shown that perfluorooctane sulfonate (PFOS) increases the toxicity of other chemicals by enhancing their uptake by cells and tissues. The present study aimed at testing whether the underlying mechanism of enhanced uptake of chemicals by zebrafish (Danio rerio) embryos in the presence of PFOS is by interference of this compound with

Mechanochemical destruction of perfluorooctane sulfonate (PFOS) using boron carbide (B4C)

Journal of Hazardous Materials
Widespread detection in soils and sediments underscores the potential threats posed by persistent, bioaccumulative and toxic perfluorooctane sulfonate (PFOS) to ecosystems and organisms. Nevertheless, the formidable energy of the C-F bond imparts stability and hampers degradation.
