The ecotoxicological characterisation of waste according to the European List of Wastes (Decision 2000/532/EC) is part of the assessment as hazardous or non-hazardous. So far, guidance is lacking regarding the evaluation of the hazard property ‘ecotoxic’ (HP 14; formerly H 14) using biotests. Based on the recommendations of EN 14735 and experiences made in an […]
The aims of this project were the compilation and publication of the results of workshops with international dung fauna experts (Aveiro group) and the further improvement of existing laboratory tests with dung beetles and dung flies. Two publications were prepared: first, recommendations for the preparation, performance and assessment of field studies with dung organisms, and […]
On the basis of ecotoxicological tests performed with soil organisms, recommendations for precautionary values were given for 16 metals and 10 organics. In the case of three substances (antimony, beryllium, vanadium), the amount of data was not sufficient for such a derivation, while for arsenic, lead, cadmium, chromium, cobalt, copper, molybdenum, nickel, mercury, selenium, thallium, […]
The most likely entry pathways of veterinary medicinal products (VMPs) into the environment are via slurry or manure from intensively reared animals to soil, and via dung or urine from animals grazing on pasture. Surface water may be contaminated via run-off or leaching and drainage, or by direct excretion of pasture animals into water. According […]
The aim of the project was to evaluate the environmental relevance of potential endocrine disrupters in surface waters by comparing measured concentrations of the respective substances to newly proposed environmental quality standards (EQS). As a key action of the European Commission’s strategy for endocrine disrupting chemicals, 564 potential endocrine disrupters had been listed. Further 88 […]
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 […]
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 […]
Edaphobase is a database project aiming to bring together information concerning taxonomy and ecology of important soil invertebrate taxa. Data will be extracted from literature, collections and unpublished material from research institutions with a focus on Germany and its neighboring countries. Linking such data on different soil organism groups from several trophic levels with climatic, […]
In current bioassay approaches for assessing sediment toxicity, whole organisms or in vitro systems are exposed to various sediment fractions (e.g. whole sediment, pore water, extracts) considering different exposure scenarios. Whole-sediment exposure protocols represent the most realistic scenario. However, until now the interpretation of sediment contact test results is associated with uncertainties due to the […]
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 […]
