Critical Review of Thermal Decomposition of Per- and Polyfluoroalkyl Substances: Mechanisms and Implications for Thermal Treatment Processes
Science
2 May 2022 | Environ Sci Technol
This review discusses thermal treatment as a way to destroy PFAS, and highlights that a major weakness of existing studies is that they do not mimic the full-scale thermal treatment systems that are actually used for PFAS incineration.

Levels and Temporal Trends of Trifluoroacetate (TFA) in Archived Plants: Evidence for Increasing Emissions of Gaseous TFA Precursors over the Last Decades
Science
26 Apr 2022 | ES&T
TFA concentrations in plants were found to increase over several decades, likely due to increasing anthropogenic emissions of TFA precursors. The very high persistence and mobility of TFA in the environment mean that TFA and its precursors should be considered for regulation.
