Correction to Alternative and Legacy Perfluoroalkyl Substances: Differences between European and Chinese River/Estuary Systems Franziska Heydebreck,* Jianhui Tang,* Zhiyong Xie, and Ralf Ebinghaus Environ.

We discovered an error in the calculation of our published data. The calculated water concentrations in ng/L were calculated too low by a factor of 20%. The error arose during the quantitative evaluation with our measurement software Analyst. This means that all concentrations are higher than the published concentrations by a factor of 20%. All values have been corrected in the Supporting Information (Tables S4−S5). Additionally, all figures have been corrected (Figures 2 and 3 and Figures S2−S5). The corrected values do not affect the discussion and conclusion of our paper because all concentrations were calculated too low by the same factor.
