Recent advances on PFAS degradation via thermal and nonthermal methods

PFAS in Nigeria: Identifying data gaps that hinder assessments of ecotoxicological and human health impacts

“…The persistence of PFAS is due to their strong carbon-fluorine bonds, which resist photolytic, biological, and hydrolytic degradation [ 47 ]. As a result, PFAS can remain intact in the environment for years, if not decades, earning them the moniker “forever chemicals” [ 48 ].…”

Comprehensive Review of Crystalline Silicon Solar Panel Recycling: From Historical Context to Advanced Techniques

“…Recycling solar panels presents several environmental challenges. These include the release of harmful gases such as hydrofluoric acid during chemical treatments, exposure to toxic dust and noise during physical processes such as high voltage crushing, and the high energy consumption of thermal methods [23,42,85,87]. Additional issues such as nitrogen oxide emissions during EVA layer separation by nitric acid dissolution [21,56], waste disposal complications, and the prolonged dissolution time of the EVA layer using traditional organic solvents [88].…”

Global Perspective on the Impact of Plastic Waste as a Source of Microplastics and Per- and Polyfluoroalkyl Substances in the Environment

“…However, while the fluorinated chain remains durable in natural settings, the functional groups within PFASs may be susceptible to environmental modifications, such as those originating from fluorotelomers. 16 In particular, MPs and PFASs with opposite charges have the propensity to be electrostatically adsorbed, but when they have the same charge, electrostatic repulsion occurs. 17 The electrical charge of MPs and PFASs can be affected by various factors, including functional groups, distinct molecular compositions, and environmental conditions.…”

“…PFASs are characterized by their remarkable chemical stability due to the robust C–F bonds. However, while the fluorinated chain remains durable in natural settings, the functional groups within PFASs may be susceptible to environmental modifications, such as those originating from fluorotelomers . In particular, MPs and PFASs with opposite charges have the propensity to be electrostatically adsorbed, but when they have the same charge, electrostatic repulsion occurs .…”
