River sediment was collected from a monitoring station lagoon on the River Elbe
close to the Czech-German border. Assessed values for extractable metals precisely
following the ISO11466 (1995) method. Only those metals that reached a plateau of
concentration after two hours reflux were characterised.
This material is intended for use as a reference material in the development,
validation or quality control of analytical methods for the determination of extractable
metals in sediments.
