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. Du... read more
