Comment on “Assessing the atmospheric fate of trifluoroacetaldehyde (CF3CHO) and its potential as a new source of fluoroform (HFC-23) using the AtChem2 box model” by Pérez-Peña et al., Environ. Sci.: Atmos., 2023, 3, 1767–1777, DOI: 10.1039/D3EA00120B
Recently Pérez-Peña et al. published a paper in this journal on the potential atmospheric fate of trifluoroacetaldehyde (CF3CHO) as a source of CF3H (HFC-23). In their work they utilized both a box model and a global chemistry and transport model to evaluate the production of CF3H from the photolysis of CF3CHO, the latter generated from photochemical oxidation of HFO-1234ze (CF3CHCHF). Certain chemical assumptions and simplifications were made. We believe the assumptions utilized by Pérez-Peña et al. misrepresent the environmental fate of CF3CHO. In the following, we present our comments on both the photolysis and the wet and dry deposition of CF3CHO. Furthermore, we contemplate the impact of the potential deposition of CF3CHO on the formation of trifluoroacetic acid (CF3COOH) during the environmental processing of CF3CHO.
