Human gut bacteria bioaccumulate per- and polyfluoroalkyl substances

Nature Microbiology
Abstract Per- and polyfluoroalkyl substances (PFAS) are persistent pollutants that pose major environmental and health concerns. While few environmental bacteria have been reported to bind PFAS, the interaction of PFAS with human-associated gut bacteria is unclear.

Bifunctional Reduced Graphene Oxide Derivatives for PFOA Adsorption

ChemistryEurope, EarlyView.
A bifunctional graphene‐based material is developed for selective PFAS adsorption from water. Thermally reduced graphene oxide is modified with quaternary ammonium groups and fluorinated chains, promoting electrostatic and fluorine–fluorine interactions. Surface functionality is characterized by X‐ray photoelectron spectroscopy, atomic force microscopy,

Per- and polyfluoroalkyl substances: toxicokinetics, exposure and health risks

The Journal of Toxicological Sciences
Per- and polyfluoroalkyl substances (PFAS) are a group of chemicals containing stable per- or polyfluoroalkyl groups. Recent epidemiological studies have shown that PFAS cause health risks even at low concentrations. This review outlines the toxicokinetics, exposure and health risks of PFAS, with a focus on perfluorooctane sulfonic acid (PFOS ...

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...

Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

Journal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.
