Corrigendum to ‘A national-scale preliminary overview study of poly- and perfluoroalkyl substances (PFAS) occurrence in aquatic environments of England, UK’ [Chemosphere 394 (2026) 144804]

The authors regret that the tables in the Appendix associated with this journal entry contain a unit error. In Table S1, the unit in the heading for the Limit of Detection (LOD) should be reported as μg/L rather than ng/L. This error affects the calculations presented in the paper, as non-detects were treated as 0.5 × LOD.
We believe the most effective change is to revert all <LOD values to 0 (a widely accepted method, aligned with the Drinking Water Inspectorate (DWI) approach1), since the existing < LOD values are very small. Therefore, the changes to the sum of all PFAS are fairly negligible. A histogram summarising the net change across all sites is provided below. An example of dummy data is provided below also.
