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.
