... similar to acetic acid, but with fluorine atoms replacing hydrogen. The strong carbon-fluorine bonds make TFA extremely stable and nearly indestructible through natural processes. This substance belongs to the class of "forever chemicals" (PFAS)—fluorine-containing compounds capable of persisting in the environment for decades without breaking down. Rising Concentrations: Recent Studies Recent studies have shown a significant increase in the levels of trifluoroacetic acid in nature. Sample ...
