Detection of Perfluorooctane Surfactants in Great Lakes Water

Environmental Science & Technology, 2004
Widespread use of perfluorooctane surfactants has led to ubiquitous presence of these chemicals in biological tissues. While perfluorooctane surfactants have been measured in blood and liver tissue samples of fish, birds, and mammals in the Great Lakes region, data for the aqueous concentrations of these compounds in the Great Lakes or other ambient ...

Uptake of perfluorooctanoic acid, perfluorooctane sulfonate and perfluorooctane sulfonamide by carrot and lettuce from compost amended soil

Science of The Total Environment, 2016
Sewage sludge, which acts like a sink for many pollutants, including metals, pathogens and organic pollutants, that are not completely removed in waste water treatment plants (WWTPs), is applied as a nutrient rich organic fertilizer in many agricultural applications.

Mechanistic understanding of perfluorooctane sulfonate (PFOS) sorption by biochars

Chemosphere, 2023
Biochar has recently emerged as a cost-effective solution to combat per- and polyfluoroalkyl substances (PFAS) pollution in water, but mechanistic understanding of which physicochemical properties of biochars dictate PFAS sorptive removal from water remains elusive. Herein, 15 biochars were pyrolyzed from five feedstocks (corn, Douglas fir, eucalyptus,

Kinetic Stability of Toluene‐Perfluorooctane Emulsions

Journal of Dispersion Science and Technology, 2007
The miscibility of toluene‐perfluorooctane‐mixtures was investigated and compared to the predictions of some commonly used models. Functional surfactant precursors and nonreacting surfactants were used for emulsifying toluene in perfluorooctane. The effect of surfactant concentration, temperature and volume fraction of toluene on the emulsion stability

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.

Perfluorooctane sulphonate (PFOS) throughout the food production chain

Food Chemistry, 2011
Perfluorooctane sulphonate (PFOS) is a persistent organic pollutant with adverse effects on human health. Since dietary intake plays an important role in human exposure, the transfer of PFOS throughout the food chain needs further investigation. The aim of this paper is to give an overview of PFOS concentrations and transfer for the various chain steps

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

EXPERIMENTAL INTRAOCULAR TOLERANCE TO LIQUID PERFLUOROOCTANE AND PERFLUOROPOLYETHER

Retina, 1991
Three kinds of perfluorinated liquids (a perfluorooctane and two perfluoropolyethers) were evaluated as vitreous replacements. Tolerance to these liquids in rabbit eyes was investigated for periods of up to 2 months. Clinically, droplet formation of the liquids occurred within a few days of intravitreal injection.

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.

Lipid peroxidation and oxidative stress responses of salmon fed a diet containing perfluorooctane sulfonic- or perfluorooctane carboxylic acids

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2011
The present study was conducted to evaluate the effects of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) on lipid β-oxidation and oxidative stress responses in Atlantic salmon liver and kidney tissues. We quantified changes in the expression levels of peroxisome proliferator-activated receptors (PPARs) and acyl-CoA oxidase (ACOX1 ...
