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.

Electrochemical Reduction of Perfluorooctanoic Acid (PFOA): An Experimental and Theoretical Approach.

Journal of the American Chemical Society
Perfluorooctanoic acid (PFOA) is an artificial chemical of global concern due to its high environmental persistence and potential human health risk. Electrochemical methods are promising technologies for water treatment because they are efficient, cheap,

Sonication-assisted photocatalytic decomposition of perfluorooctanoic acid

Chemosphere, 2009
Decomposition 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 ...

Assessment of perfluorooctanoic acid toxicity in pancreatic cells

Toxicology in Vitro, 2021
Perfluorooctanoic acid (PFOA) was classified as a possible carcinogen for humans (Group 2B). The in vivo studies have reported that PFOA might lead to hepatic, testicular and pancreatic toxicities and cancers. However, its mechanisms in pancreatic tissue are still unclear and insufficiently discussed.

Perfluorooctanoic acid triggers oxidative stress in anaerobic digestion of sewage sludge.

Journal of Hazardous Materials, 2021
Perfluorooctanoic acid (PFOA), as a recalcitrant organic pollutant, inevitably enters wastewater treatment facilities and is enriched in settled sludge. However, the potential impact of PFOA on sludge treatment has never been documented.
