Ring test with dung beetles

European legislation requires testing of parasiticides using, among others, dung beetles (OECD GD 122). Currently, Aphodius constans, a dweller species, has been approved as a test species for residues in dung. However, results of tests using A. constans may not be relevant for tunneler species.

Comparison of the environmental properties of parasiticides and harmonisation of the basis for environmental assessment at the EU level

Avermectin and milbemycin parasiticides have a high toxicity to non-target organisms, are often persistent and may have a potential to bioaccumulate. The present project contributes to filling gaps in the database for a complete environmental risk assessment of these parasiticides. In addition, risk management strategies for parasiticides used in pasture animals were discussed. For ivermectin […]

Novel processing routes for effective sewage sludge management (ROUTES)

The ROUTES project aimed to evaluate new routes of sewage sludge treatment and management matching the needs of different wastewater origins and different digested sludge utilisations. Elimination of micropollutants was targeted for agricultural sludge application, and minimising the production volume for other sludge disposal routes. Research of ECT in sludge-soil interactions focussed on three aspects: […]

Selection of test organisms for the environmental risk assessment of genetically modified plants: applying and testing a new selection procedure

Since almost two decades now, chemical stressors such as pesticides are subjected to a number of standardised ecotoxicity tests for regulatory approval prior to their release to the environment. Since the advent of the technology, genetically modified organisms (GMOs) in general, and genetically modified plants (GMPs) in particular have been a contentious issue  and, very […]

Identification of wastes hazardous to the environment in mirror entries of the AVV

The ecotoxicological characterisation of waste according to the European Waste List is part of the assessment as hazardous or non-hazardous. So far, no methodological details have been fixed concerning the hazard criterion H14 (‘ecotoxic’). Using the recommendations of the CEN Guideline 14735 (2005), experiences made in an international ring test sponsored by UBA, and a […]

Development of an integrated land management for sustainable water and material usage in North-Eastern Germany (ELaN)

Treated wastewater is commonly disposed of in Germany by discharge into surface waters. Within the project ELaN, alternative approaches were investigated for dealing with treated wastewater. Main focus was placed on re-use to recycle valuable nutrients and to help prevent falling water levels in Northeast Germany. In part F (‘Ecotoxicology’) of the project, ECT investigated […]

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 […]
