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 (PFOA) exposure affects early embryonic development and offspring oocyte quality via inducing mitochondrial dysfunction.

Environment International, 2022
Perfluorooctanoic acid (PFOA) is a synthetic perfluorinated compound that is extensively used as an integral surfactant in commercial production. Owing to its hydrophilicity and persistence, PFOA can accumulate in living organisms and induce severe ...

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 ...

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.

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 ...

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 ...

Thermal degradation of perfluorooctanoic acid (PFOA)

Global NEST International Conference on Environmental Science & Technology, 2022
Per - and polyfluoroalkyl substances (PFAS) are a group of environmental contaminants, that are dispersed throughout the world. A number of areas have been affected by their persistence and biomagnification. PFAS remediation of contaminated material requires extensive knowledge of the species involved.
