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


Effect study "Irgarol"

Pigment analyses of aufwuchs (biological surface film) in stagnant water mesocosms under the effect of the anti-fouling agent Irgarol®Irgarol® is in the group of s-triazines and a biocidal agent which is used as an anti-fouling coating for marine vessels to prevent the attachment of algae and organisms on their hulls. Irgarol inhibits photosynthesis and is highly toxic for higher plants, algae and... 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


Initial plant tests (calibration phase)

The main objectives of the test phase (calibration phase) were to ensure that the plant’s basic functions were working properly, as well as to define key parameters. The experiences are documented in a technical-scientific manual, which will help researchers to become familiar with the opportunities offered by the FSA and provide important information for the planning of projects in the future.
