Short summary
Perfluoroaldehydes are important products formed in the atmospheric oxidation of fluorinated compounds. However, their degradation routes are not clear. Here, we find a rapid route for the degradation of linear perfluoroaldehydes by hydroperoxy radical. The chemical processes are dominant over the corresponding oxidation processes by hydroxyl radical. The present findings are of great importance for elucidating the chemical transformation of linear perfluoroaldehydes in the atmosphere.
