Ecophysiological and Ecotoxicological Aspects of A Closed, Self-sustaining, Aquatic Life Support System 2000-01-2339

Ecophysiology as well as Ecotoxicology are main research areas coming to a better understanding of our Earth's Ecology. However, data obtained by this research can be transferred easily to space application.
A controlled aquatic unit was developed, in which plants, fish, snails, shrimps and microorganisms can be reared in parallel.
In a first approach the system behavior of the biological unit is investigated having it either completely closed or open with an “artificial lung” implemented.
It could be demonstrated that the implementation of this artificial lung stabilizes the system enabling test runs over 4 weeks total duration.
A second approach concentrates on the application of this multi-species system in ecotoxicological research. The influence of toxic chemicals, controlled introduced into the unit, on the ecosystem behavior is under investigation.
One of the chosen toxic test substance is TBT (Tributyltin) an antifouling agent - well known polluting marine and limnic ecosystems. Test runs are in progress, however, first results can be presented at the assembly.
