Development of ecotoxicological tests with biocides and eluates: verification of the suitability of the embryo test with the zebrafish (Danio rerio, DarT)

The project explored the suitability of the fish embryo toxicity test with the zebrafish, Danio rerio, (DarT) as a tool to screen for additive and non-additive effects among biocidal substances. Five biocidal products from the product type 8 (curative and preventive wood preservatives) and their individual active substances were tested in the DarT. Overall, the […]

Iron-based nanoparticles and nanocomposite structures for removal of contaminants from groundwater and sewage

In the project ‘Iron-based nanoparticles and nanocomposite structures for removal of contaminants from groundwater and sewage’ (Fe-Nanosit), Carbo-Iron®, a nanocomposite for remediation of contaminated groundwater and Pd-doted magnetite and magnetite-zeolith for treatment of industrial wastewater were developed. Since no data on ecotoxicity of these particles were available, ecotoxicity of the nanocomposites was investigated using standard […]

Development of a gene expression fish embryo test as an alternative for chronic fish tests: analysis of toxic effects using differential gene expression in the Danio rerio embryo test (Gene-DarT)

Acute and chronic fish tests are performed for the registration of chemicals, pesticides, biocides and pharmaceuticals. While the fish embryo test has been developed as an alternative to the acute fish test, so far no alternatives for chronic fish tests are available. Therefore, the fish embryo test with the zebrafish (Danio rerio) was extended by […]

Cause-effect relations of key pollutants on the European rivers biodiversity (KEYBIOEFFECTS)

The overall objective of the research and training network KEYBIOEFFECTS was to provide young scientists with the skills and knowledge needed to assess the effects of pollution (with specific focus on key pollutants) on the biodiversity of European rivers and to transfer this knowledge to different stakeholder groups. Recognizing the importance of understanding cause-effect relationships […]

Models for assessing and forecasting the impact of environmental key pollutants on marine and freshwater ecosystems and biodiversity (MODELKEY)

The Water Framework Directive of the European Union requires a good ecological status of the European water bodies by 2015. One of the driving forces for an insufficient ecological status and reduced biodiversity of freshwater and marine ecosystems is chemical stress due to environmental pollutants. The project MODELKEY aims to contribute to the assessment, understanding […]
