Artificial stream and pond system

Hall and grounds with artificial guttering

The artificial stream and pond system (“Fließ- und Stillgewässer-Simulationsanlage” – FSA) of the German Federal Environment Agency’s field station in Berlin-Marienfelde is one of the largest and most modern mesocosm systems in the world. read more

Retention of substances (sediments, nutrients, pollutants) in river flood meadowsIn 2002 and 2003, a working group of the Institute for Geographical Sciences at the Free University (FU) Berlin carried out a study on matter retention in river flood meadows. The background for this study was the renaturation of rivers and river flood meadows, something, which has become very topical following the re... read more


Fate-Study MTBE

Behaviour of volatile substances in flowing watersAfter being discharged into runoff ditches, organic chemicals are subjected, in manifold processes, to transformation, enrichment and elimination. Volatilisation from the water body is one of the major elimination processes by which specific chemicals are irreversibly removed from aquatic ecosystems. Studies have shown that quantification of volati... read more


Effect study

In June 2003, an experiment of the effect of Metazachlor on aquatic populations was carried out in the indoor stream and pond mesocosms by the Umweltbundesamt. Metazachlor, a herbicide, belongs to the family of alpha-chloracetamides and is used, among other things, to keep grasses and weeds in the cultivation of rape, cabbage and soy beans under control. Even when applied in the appropriate manner... read more
