Peroxidase-mediated degradation of perfluorooctanoic acid

Environmental Toxicology and Chemistry, 2009
Abstract 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 induces hepatocellular endoplasmic reticulum stress and mitochondrial-mediated apoptosis in vitro via endoplasmic reticulum-mitochondria communication.

Chemico-Biological Interactions, 2022
Perfluorooctanoic acid (PFOA) is a persistent organic pollutant that is widely distributed in the natural environment. Cohort study showed that PFOA-producing workers displayed a significant increase for mortality of liver cancer and liver cirrhosis ...

Perfluorooctanoic acid (PFOA)

2021
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).

Investigating the biodegradability of perfluorooctanoic acid

Chemosphere, 2010
Perfluorooctanoic acid (PFOA) is an industrial chemical that has become disseminated globally in aquatic and terrestrial habitats, humans, and wildlife. Understanding PFOA's biodegradability (susceptibility to microbial metabolic attack) is a crucial element in developing an informed strategy for predicting and managing this compound's environmental ...

Effects of perfluorooctanoic acid on Microcystis aeruginosa: Stress and self-adaptation mechanisms.

Journal of Hazardous Materials, 2022
The persistent organic pollutant perfluorooctanoic acid (PFOA) is ubiquitous in aquatic environments. However, little is known about its toxicity to microalgae or the mechanisms by which they may self-adapt to it.

Perfluorooctanoic acid and ammonium perfluorooctanoate: volatile surfactants for proteome analysis?

Rapid Communications in Mass Spectrometry, 2012
RATIONALE 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, 1987
AbstractRates 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 ...
