The Government has no current plans to commission independent research on this topic. Evidence tells us that the primary source of trifluoroacetic acid in the environment is believed to be through atmospheric oxidation of the CFC-replacement gases, HCFC-123 and HFC-134a, though various fluorochemicals have the potential to degrade to trifluoroacetic acid.

Trifluoroacetic acid is one of a group of thousands of substances collectively called poly- and per-fluorinated substances (PFAS), which are highly persistent in the environment. As a group they are being considered under a risk management options analysis under UK chemical regulation (UK REACH). The Environment Agency also considered Trifluoroacetic acid as part of its priority and early warning system for chemicals.

My Department has had no discussions with the German Federal Environment Agency regarding their reports on trifluoroacetic acid but is aware of its monitoring approach.
