Electrochemical treatment of PFAS in fractionated foam

Frontiers in Environmental Science
Foam fractionation is emerging as a promising option to remove and concentrate PFAS from polluted water and soil resources. Here, we investigate the electrochemical treatment of foamate resulting from the simultaneous application of soil washing and foam

Vapor‐Phase Detection of Perfluoroalkyl Acids using Amplifying Fluorescent Polymers

Small Methods, EarlyView.
Amplifying fluorescent fluorous polymers respond to PFAS vapors in under 5 s. The fluorophilic nature of the polymers results in strong binding and selectivity. ABSTRACT Perfluoroalkyl acids are a subclass of persistent toxic per‐ and polyfluoroalkyl substances (PFAS) whose volatility enables airborne exposure pathways that remain largely unmonitored ...

Multistressor Interaction of Perfluorooctane Sulfonate (PFOS) and Temperature in Two Estuarine Fish Species, Red Drum (Sciaenops ocellatus) and Sheepshead Minnow (Cyprinodon variegatus)

Environmental Toxicology, EarlyView.
ABSTRACT Perfluorooctane sulfonate (PFOS), a perfluoroalkyl substance (PFAS), is characterized by a long, fluorinated carbon chain which makes it ideal for oil‐ and water‐repellent products but detrimental for the environment, where it persists and accumulates in organisms.

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Plasma perfluoroalkyl substances and breast cancer risk in Brazilian women: a case–control study

Environmental Health
Background Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants, and have been detected in human blood. Although PFAS may increase the risk of breast cancer in humans, findings from previous epidemiological studies on the ...

Demonstration of a High‐Resolution Passive Profiler for Characterizing the Distribution of PFAS in Groundwater: A Comparison of Methods in the Field

Groundwater Monitoring &Remediation, EarlyView.
Abstract Characterizing the concentration and mass flux spatial distributions at sites with complex hydrogeologic conditions is critical to evaluate the fate and transport of contaminants, as well as to design effective remediation programs. PFAS (per‐ and polyfluoroalkyl substances)‐contaminated sites are even more complex due to the large number of ...
