Polypyrrole Nanofibrous Aerogel for Pressure Sensing and Anionic Contaminant Remediation

Small, EarlyView.
Nanofibrous aerogels (NFAs), highly porous ultralow‐density networks of entangled nanofibers, are conformally coated with polypyrrole (PPy) to provide a multifaceted material platform. Leveraging NFA's high surface area and mechanically robust structure with the conductive properties of PPy enables pressure‐responsive sensing for flexible electronics ...

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 ...

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.
