Department of Ecotoxicology (Institute for Ecological Research and Technology, Technical University of Berlin. Major research areas are: Fisheries and ecological status of habitats. Effects Monitoring (freshwater and marine) and the study of detoxification processes using modern methods to assess DNA damages (Genotoxicity, Xenoestrogens, Immunosuppression, Phagocytosis). Development of modern bioanalytical systems and (on-line) monitoring systems, entire cell bio-sensors. Development and testing of cost efficient screening methods (genotoxic potential, endocrine effects and immunosuppression) in inland and coastal waters. Landscape scale ecotoxicology in respect to the Water Frame Work Directive and REACH. Risk assessment, -communication and -management in constructions and materials.
