Accumulation of PFOA and PFOS at the Air–Water Interface

Environmental Science and Technology Letters, 2019
Knowledge of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) accumulation at the air–water interface is critical to understanding the fate and transport of these substances in...

Decomposition of perfluorooctane sulfonate (PFOS) using a hybrid process with electron beam and chemical oxidants

Chemical Engineering Journal, 2019
Among many contaminants of emerging concern, perfluorooctanesulfonate (PFOS) is widely known as one of the most difficult to decompose due to a very strong carbon-fluorine bond.

PFOA and PFOS interact with superoxide dismutase and induce cytotoxicity in mouse primary hepatocytes: A combined cellular and molecular methods.

Environmental Research, 2019
This study investigated the adverse effects of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) on mouse primary hepatocytes by conducting cell viability, apoptosis, intracellular oxidative stress level, superoxide dismutase (SOD ...

Neonatal and juvenile exposure to perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS): Advance puberty onset and kisspeptin system disturbance in female rats.

Ecotoxicology and Environmental Safety, 2019
Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) are widespread and persistent chemicals in the environment, and limited data about their effects on puberty development are available. In order to explore the effects of neonatal and juvenile

PFO management: Neurologists vs cardiologists

Neurology, 2005
Patent foramen ovale (PFO) is associated with stroke, particularly in younger patients without another identifiable etiology. Therapeutic options available include antiplatelet medications, warfarin, surgical closure, or percutaneous closure, yet there have been no adequate head-to-head trials to guide management decisions.1 We conducted a survey of ...

A sensitive and selective triple-channel optical assay based on red-emissive carbon dots for the determination of PFOS

Microchemical journal (Print), 2019
In this study, a simple, fast and cost-effective triple-channel optical assay for the determination of PFOS has been developed. The carbon quantum dots (CDs) were prepared by one-pot hydrothermal method and employed as probe for sensing PFOS.
