摘要

Due to a calibration problem with the targeted analysis affecting only the Canadian products (n = 17), in our original article (https://pubs.acs.org/doi/10.1021/acs.estlett. 1c00240), data for Canadian products were requantified using the isotopically labeled surrogate standards. Each target compound was assigned to a specific surrogate standard as described in Table S7 of the Supporting Information. As a result of the requantification of the Canadian samples, the sum of PFAS concentrations for Canadian samples has decreased, and the detection frequency of individual analytes shifted. Out of the 231 total U.S. and Canadian samples analyzed with PIGE, 29 were selected for further targeted analysis. Of those 29, 17 (only the Canadian samples) were affected by the issue described above. The error involves less than 7% of the data reported in the paper. For six samples, PFAS concentrations were more than 50 times lower, while for the remaining 13 samples, the corrected concentrations were less than 20 times lower. While some of these changes are significant in absolute terms, the overall content and conclusions of the paper remain unchanged as described in more detail below.
