Evaluation of a biotest battery for the ecotoxicological characterisation of waste: ring test with 60 laboratories from 15 countries

The ecotoxicological characterization of waste is part of its assessment as hazardous or non-hazardous according to the European List of Wastes (LoW, 2000/532/EC) amended by Directive 2008/98/EG and Regulation 2017/997. For this assessment, 15 hazard properties are evaluated. So far, there is no harmonised guidance for evaluation of the hazard property ‘ecotoxic’ (HP 14) using […]

Validation of a method to measure bioaccumulation in terrestrial organisms by means of an international ring test

The aim of the project was the validation of a bioaccumulation test with terrestrial organisms (soil dwelling oligochaetes) by an international ring test. The test method was developed taking into account existing methods (UBA-reports 206 03 909 (1997) and 298 64 416 (2001)). A test protocol was prepared and used to run the test. A […]

Determination of developmental toxicity to dipterian dung flies

The aim of the project was to standardise a test guideline with two dung fly species to be used for the environmental risk assessment of veterinary pharmaceuticals, in particular endo- and ectoparasiticides excreted in dung. The test is designed to evaluate developmental toxicity of a test substance to the dung dwelling life stages of dung-dependent […]

Supply of dung beetles for the performance of a ring test as a precondition for the implementation of an OECD Guidance Document

The objective of this project sponsored by the German Federal Environment Agency was the improvement of existing laboratory tests with dung beetles and dung flies. It was aimed at identifiying a second dung beetle species for standardised laboratory tests that should belong to the ecological group of ‘tunnelers’.  However, it was not possible to establish […]

Development of a standardised laboratory test with dung beetles for the assessment of the ecotoxicity of veterinary pharmaceuticals

According to European law, the environmental risk assessment of veterinary pharmaceuticals for dung beetles is required for parasiticides for the treatment of pasture animals. Starting with recommendations from the SETAC advisory group DOTTS (Dung Organism Toxicity Test Standardisation), a test system using the widespread temperate dung beetle species Aphodius constans was developed. Together with the […]

Organisation and performance of an international ringtest for the validation of the enchytraeid reproduction test

An enchytraeid reproduction test ring test was performed in line with OECD requirements. Twenty-nine institutions (mainly universities and contract research laboratories) from 15 countries from Europe and North America participated in this ring test. The co-ordinating laboratory centrally distributed the test chemicals, guidance papers and test organisms to all participants. In addition, several training courses […]

Ecological impacts of land application of biosolids on soil-dwelling organisms

In a long-term experiment run by Agriculture & Agri-Food Canada, the fate of pharmaceuticals and other substances contained in biosolids was followed after farm-scale application to agricultural land on an experimental field site in Ottawa. In the context of this experiment, ECT followed the development of nematode and enchytraeid communities over several years after the […]

Hardly soluble active ingredients of cosmetics – ecotoxicology and substitution

The aim of this project was to develop tools and to experimentally verify proposed assessment schemes such as the ‘poorly soluble approach‘ in order to enable a better assessment of highly lipophilic substances. In the context of a PhD project, selected highly lipophilic compounds present in personal care products (e.g. cosmetics) were investigated. ECT played […]

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 […]

Development of a classification and assessment concept based on biodiversity of water and soil organisms regarding the effects of climate change and anthropogenic stressors

In July 2008, a new interdisciplinary research centre was founded in Frankfurt am Main (Germany) within the framework of the LOEWE Programme, a State Government of Hesse initiative for the development of scientific and economic excellence. The mission of the new centre (BiK-F) is to carry out internationally outstanding research on the interactions of organismic […]
