Correction
to Alternative and Legacy Perfluoroalkyl
Substances: Differences between European and Chinese River/Estuary
Systems

The
production and use of long-chain perfluoro­alkyl substances
(PFASs) must comply with national and international regulations. Driven
by increasingly stringent regulations, their production has been outsourced
to less regulated countries in Asia. In addition, the fluoropolymer
industry started to use fluorinated alternatives, such as 2,3,3,3-tetrafluoro-2-(1,1,2,2,3,3,3-heptafluoropropoxy)­propanoic
acid (HFPO-DA). Between August 2013 and September 2014, we investigated
the occurrence and distribution of HFPO-DA and legacy PFASs in surface
waters of the following river/estuary systems: the Elbe and Rhine
Rivers in Germany, the Rhine-Meuse delta in The Netherlands, and the
Xiaoqing River in China. Distinct differences were revealed among
the study areas; notably, the Chinese samples were highly polluted
by an industrial point source discharging mainly perfluorooctanoic
acid (PFOA). This particular point source resulted in concentrations
more than 6000 times higher than an industrial point source observed
in the Scheur River, where HFPO-DA was the dominant compound with
a concentration of 73.1 ng/L. Moreover, HFPO-DA was detected in all
samples along the coastline of the North Sea, indicating that the
compound may be transported from the Rhine-Meuse delta into the German
Bight via the water current. To the best of our knowledge, the fluorinated
alternative, HFPO-DA, was detected for the first time in surface waters
of Germany and China
