a CF2-normalized Kendrick mass vs. AKMD of all detected ions. b CF2-normalized Kendrick mass vs. AKMD of the identified PFASs. c O/C vs. F/C of the identified PFASs. d O/C vs. (H+F)/C of the identified PFASs. The calculation procedures for the CF2-normalized Kendrick masses and AKMD were referred to the study of Liu et al.45, and are also provided in the Supplementary Information (Supplementary Equations 1-4).
