Boiling significantly promotes photodegradation of perfluorooctane sulfonate
Chemosphere, 2015The application of photochemical processes for perfluorooctane sulfonate (PFOS) degradation has been limited by a low treatment efficiency. This study reports a significant acceleration of PFOS photodegradation under boiling condition compared with the non-boiling control. The PFOS decomposition rate increased with the increasing boiling intensity, but

Mechanistic understanding of perfluorooctane sulfonate (PFOS) sorption by biochars
Chemosphere, 2023Biochar 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,

Sorption of perfluorooctane sulfonate on organo-montmorillonites
Chemosphere, 2010Perfluorinated compound as one of the emerging pollutants has caused great attention in recent years. In this study, the organo-montmorillonites (organo-Mts) with different amounts and arrangements of hexadecyltrimethylammonium bromide (HDTMAB) were prepared as effective sorbents for PFOS removal from water.

Avian Toxicity Reference Values for Perfluorooctane Sulfonate
Environmental Science & Technology, 2005Toxicity reference values (TRVs) and predicted no effect concentrations (PNECs) were derived for perfluorooctane sulfonate (PFOS) based on the characteristics of a top avian predator. On the basis of the protective assumptions used in this assessment, the benchmarks are protective of avian populations and were based on acute and chronic dietary ...

Accumulation of Perfluorooctane Sulfonate in Marine Mammals
Environmental Science & Technology, 2001Perfluorooctane sulfonate (PFOS) is a perfluorinated molecule that has recently been identified in the sera of nonindustrially exposed humans. In this study, 247 tissue samples from 15 species of marine mammals collected from Florida, California, and Alaskan coastal waters; and northern Baltic Sea; the Arctic (Spitsbergen); and Sable Island in Canada ...

Firefighters were likely exposed to perfluorooctane sulfonate since it was a component of extinguishing foams and perfluorohexane sulfonate (PFHxS), a surfactant coating carpet and other building materials, during firefighting. The objective of the study is to evaluate serum concentrations of perfluoroalkyl acids (PFAAs) in firefighters.A total of 8826

Perfluorooctane Sulfonate Concentrations in Surface Water in Japan
Archives of Environmental Contamination and Toxicology, 2003Perfluorooctane 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, 2012Sorption 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

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, 2005Perfluorooctane 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.
