Many manufactured per- and polyfluorinated alkyl substances (PFAS), like perfluorooctanoic acid (PFOA), are widely used in a number of consumer goods and have emerged as environmentally persistent pollutants. This section summarizes the toxicological effects of PFOA on wildlife and evaluates PFOA toxicity data to derive toxicity reference values (TRVs).

Peroxidase-mediated degradation of perfluorooctanoic acid
Environmental Toxicology and Chemistry, 2009Abstract Concentrations of aqueous-phase perfluorooctanoic acid (PFOA), a representative perfluorinated aliphatic (PFA) compound, are shown to be reduced effectively via reaction with horseradish peroxidase (HRP), hydrogen peroxide, and a phenolic cosubstrate (4-methoxyphenol).

Perfluorooctanoic acid and ammonium perfluorooctanoate: volatile surfactants for proteome analysis?
Rapid Communications in Mass Spectrometry, 2012RATIONALE Fluorinated surfactants are being explored as mass spectrometry (MS)‐friendly alternatives to sodium dodecyl sulfate (SDS) for proteome analysis. Previous work demonstrates perfluorooctanoic acid (PFOA) to be compatible with electrospray ionization (ESI)‐MS.

Micellar catalysis by perfluorooctanoic acid
International Journal of Chemical Kinetics, 1987AbstractRates of acidic hydrolysis of hexano‐, octano‐, and decanohydroxamic acids and of 4‐bromophenylaceto‐ and phenylacetohydroxamic acids have been determined in aqueous perfluorooctanoic acid—a reactive counterion surfactant system. Typical micellar catalysis was observed for the hydrolyses of the n‐alkyl hydroxamic acids but not for the ...

Investigations on the phytotoxicity of perfluorooctanoic acid in Arabidopsis thaliana
Environmental Science and Pollution Research, 2019Environmental contamination by perfluorooctanoic acid (PFOA) has raised concerns for years. Yet, little information on its phytotoxic effects and underlying mechanisms in higher plants is available. To this end, comparative analyses of the responses to PFOA exposure between shoots and roots in the model plant species Arabidopsis thaliana were performed

Photocatalytic Degradation of Perfluorooctanoic Acid
2014Perfluorooctanoic acid (PFOA) is an emerging persistent organic pollutant receiving increasing attention due to its global occurrence and resistance to most conventional degradation methods. Some special techniques such as ultrasonication, aqueous electron reduction, persulfate photolysis, and phosphotungstic-acid photocatalysis have been developed to ...

Sonication-assisted photocatalytic decomposition of perfluorooctanoic acid
Chemosphere, 2009Decomposition of perfluorinated chemicals is of significant interest in both scientific and industrial perspectives. Here, we report the decomposition of perfluorooctanoic acid (PFOA) under sonication-assisted photocatalysis by utilizing commercial TiO(2) (RdH) and home-made TiO(2) (sol-gel) as photocatalysts at ambient temperature, pressure and near ...

Understanding the atmospheric measurement and behavior of perfluorooctanoic acid
Environmental Toxicology and Chemistry, 2012Abstract The recently reported quantification of the atmospheric sampling artifact for perfluorooctanoic acid (PFOA) was applied to existing gas and particle concentration measurements. Specifically, gas phase concentrations were increased by a factor of 3.5 and particle-bound concentrations by a factor of 0.1.

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.

ABSTRACTPerfluorooctanoic acid (PFOA) contamination in the environment is a global problem. The aqueous phase is the main medium for PFOA because of its moderate solubility. Adsorption is a feasible way to remove PFOA because of its chemical and biological stability.
