https://pubmed.ncbi.nlm.nih.gov/27351319/ https://pubmed.ncbi.nlm.nih.gov/27351319/ This summarizes the dangers of trifluoroacetic acid (TFA). It’s a small polar compound that has low potential for toxicity. I mean not great that it is in drinking water but in the grand scheme of things it could be much worse. >As an acid or as a salt TFA is low to moderately toxic to a range of organisms. Based on current projections of future use of HCFCs and HFCs, the amount of TFA formed in the troposphere from substances regulated under the MP is too small to be a risk to the health of humans and environment.
