Perfluoroalkyl Substances (PFASs) in the Canadian Freshwater Environment. [PDF]

Archives of Environmental Contamination and Toxicology, 2021
Abstract Per- and polyfluoroalkyl substances (PFASs) are anthropogenic substances that are very stable in the receiving environment. PFASs are persistent and resistant to typical environmental degradation processes and therefore are distributed across all trophic levels and environmental compartments (soil, air, water). Since most uses of PFOS,

Per- and polyfluoroalkyl substances (PFASs) in surface water of the North and Baltic Seas in 2016/2017

, 2021
Along with the phase-out of legacy long-chain perfluoroalkyl carboxylic acids (PFCAs), perfluoroalkane sulfonic acids (PFSAs) and their precursors, attention has been drawn to emerging per- and polyfluoroalkyl substances (PFASs).

Titanium‐Catalyzed Defluorination of Poly(Vinyl Fluoride) and Poly(Vinylidene Fluoride) Under Friedel–Crafts Conditions

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Cationic titanium sandwich catalysts display exceptional activity in the hydrodefluorination of Csp3─F bonds, in the presence of silanes and aromatic solvents (turnover numbers up to 3000). As a result, they can be used to defluorinate challenging fluoropolymers, such as poly(vinyl fluoride) (PVF) or poly(vinylidene fluoride) (PVDF).
