ACCELERATING. FOREVER CHEMICALS. ELIMINATION.

Nagoya Institute of Technology researchers have developed a PFAS-free fluorine-synthesis method that enables efficient skeletal editing of benzene into azepine rings. They achieved this by using high-valent sulfur fluorides (SF?/SF?) as reactivity switches, which activate the ring and drive the transformation under visible light. This approach provides the benefits of fluorine chemistry without relying on persistent PFAS, offering a cleaner path for designing future pharmaceuticals and functional materials.

The EPA recently approved certain pesticide products that contain a single fluorinated carbon—an ingredient structure that, under the agency’s current definition, does not qualify as a PFAS. Following public claims that it had authorized a new “forever chemical,” the EPA issued a detailed fact-check explaining that these substances are chemically distinct from persistent PFAS, fall outside the regulatory definition, and have undergone the same rigorous toxicological and environmental review required for all pesticide registrations.

Milliken & Company and Numat Technologies have formed a strategic partnership to develop advanced protective textiles using Numat’s MOF-based Sentinel® technology. The collaboration focuses on delivering high-performance, non-PFAS protection solutions for defense, industrial, and first-responder applications.

The European Parliament has adopted a new regulation updating EU toy?safety rules the update bans harmful chemicals in toys, including endocrine disruptors, skin sensitisers, PFAS (“forever chemicals”) and the most dangerous bisphenols, and introduces mandatory “digital product passports” for all toys imported or sold in the EU. The change aims to strengthen child health protection by making toys safer, improve traceability and market?surveillance, and adapt toy?safety regulation to the realities of rising online and cross?border toy sales.

This study investigated electrochemical oxidation of perfluorooctanoic acid (PFOA) using a Bi2O3–SnO2 catalyst supported on a Ti4O7 reactive electrochemical membrane (BTO/REM). In an inert NaClO4 electrolyte, the BTO/REM achieved 98.1 ± 0.4% PFOA removal, 85.6 ± 3.6% fluoride yield, and 94.4 ± 4.6% total fluorine balance at 4.2 V/SHE and a 60 s hydraulic residence time (tr). Perfluoroalkyl carboxylates (PFCAs) with three to six perfluoroalkyl carbons formed at a combined yield of 15.3 ± 2.6%. In real groundwater, PFOA removal was limited (?1%) due to low ionic conductivity, but adding NaClO4 increased removal to ?91% at 4.7 V/SHE with tr of 15 s.

This study highlights that ultrashort-chain PFAS dominated the PFAS signature in serum samples of Wilmington, NC, residents collected between 2010 and 2016. At the measured serum levels, ultrashort-chain PFAS may be an important contributor to PFAS-associated toxicity.

Per-and polyfluoroalkyl substances (PFAS) pose a global threat due to their environmental persistence and bioaccumulation. Polyvinylidene fluoride (PVDF), as a high-performance fluoropolymer, is indispensable in many fields and cannot be completely phased out in the short term. This has led to a dilemma between the necessity of PVDF and its environmental risks throughout its life cycle, which has become a core bottleneck in the regulation of fluorochemicals. In light of this, this study converts recycled PVDF into microparticles for application in the field of supercapacitor energy storage. The prepared electrode with PVDF micro-particles not only achieves an ultra-high mass loading of 100 mg cm?2, an ultra-high specific capacitance of 31.4 mAh cm?2, and ultra-long cycling of more than 15 000 cycles, but also realizes an ultra-high energy density of 29.7 mWh cm?2.

The remediation of perfluorooctanoic acid (PFOA) remains a critical challenge due to its exceptional chemical stability and bioaccumulation risks. Here, we present two pyrene-based multicomponent metallacages that synergistically integrate high-capacity adsorption and photocatalytic degradation of PFOA. The 4,4’-bipyridine tetracarboxylate-derived metallacage demonstrates a high PFOA adsorption capacity of 1223 mg/g, facilitated by multivalent electrostatic interactions and hydrogen bonds. Subsequent photocatalytic treatment of the preconcentrated PFOA achieves 91% defluorination within 6 h through a superoxide radical-mediated chain-shortening mechanism, as verified by electron paramagnetic resonance and intermediate analyses.
