A novel aquatic bioassay with Lemna minor (duckweed), a representative of higher plants, was applied to pore waters (interstitial waters) from river sediments. The results have been used for the ecotoxicological assessment of sediments in several German rivers. The aim of the present study is to demonstrate the usefulness of a macrophyte bioassay, as a supplement to the standardised algae bioassays, with regard to the ecotoxicological assessment of aquatic systems. Results relating to the development of a sediment contact test (using the whole sediment) with Lemna minor are also presented.
