Perspective
Chemical transformation, exposure assessment, and policy implications of fluorotelomer alcohol partitioning from consumer products to the indoor and outdoor environment—from production to end-of-life
Much is known about fluorotelomer alcohols (FTOHs) in consumer products and FTOHs release to the environment. This Perspective provides some understanding of the release of FTOHs to the environment throughout the lifetime of consumer products.
Tutorial Review
Do Arctic local sources of pollution influence the exposure of ringed seals (Pusa hispida) analyzed in contaminant monitoring programs?
Contaminants have been monitored in Arctic ringed seals for decades and their exposure may be influenced by local sources of pollution.

Presence of per- and poly-fluoroalkyl substances (PFAS) in brain samples of marine mammals from the St. Lawrence Estuary and Gulf, Canada
Paper
Per- and polyfluoroalkyl substances (PFAS) as environmental drivers of antimicrobial resistance: insights from genome sequences of Klebsiella grimontii and Citrobacter braakii isolated from contaminated soil
In vitro microcosm experiments showed that PFOA (perfluorooctanoic acid) selects for antibiotic-resistant bacteria, characterized by WGS, which displayed increased transcription of AMR genes during growth in the presence of PFOA.

Bias enhanced electro-photocatalysis on TiO2 nanoporous materials for decomposition of forever chemicals in saltwater
In this study, a TiO2-based bias-enhanced photocatalytic system was prepared with the aim of achieving high photocatalytic activity in deionized as well as in saltwater systems.
Paper
Aqueous solution degradation pathways of trimethylsiloxane surfactants
Trimethylsiloxane (TriSil) surfactants are promising, environmentally friendly alternatives to per- and polyfluoroalkyl substances (PFAS), which are global recalcitrant and persistent environmental contaminants, in aqueous film-forming fire-fighting foams (AFFF).
Paper
Surfactant-enhanced coagulation and flocculation improves the removal of perfluoroalkyl substances from surface water
Addition of cationic surfactant in combination with powdered activated carbon significantly enhanced the removal of regulated PFAS during conventional coagulation/flocculation processes.
