To verify the sensitivity of ecotoxicological tests, reference substances with known toxicity are regularly tested. Ideally, such substances lack speciﬁcity in their mode action, are bioavailable and readily attainable, and their chemical characterisation is cost-effective. Boric acid satisﬁes these criteria, but has – due to reproductive effects in humans – most recently been characterised as […]
Enchytraeids (Oligochaeta, Annelida) are regularly found in agroecosystems of the temperate regions of the world. Although less known than their larger relatives, the earthworms, these saprophagous organisms play similar roles in agricultural soils inﬂuencing soil structure and organic matter dynamics and having a central place in soil food webs. Due to difﬁculties in distinguishing the […]
Advanced wastewater treatment processes are known to be an effective tool for reducing micropollutant discharge into the aquatic environment. Nevertheless, some processes such as ozonation result in stable transformation products with often unknown toxicity. In the present study, effluents from different steps of advanced treatment were compared for their aquatic toxicity. Lumbriculus variegatus, Daphnia magna […]
On 01 February 2017, Dr. Anja Coors has been appointed as honorary visiting fellow in the Environment Department of the University of York, UK. This appointment will deepen and further develop the cooperation with the research group of Prof. Alistair Boxall…
In cooperation with several partners, a multidisciplinary concept was developed for assessing the eﬃcacy of advanced wastewater treatment methods for removal of micropollutants. This concept integrates (1) chemical parameters (the removal of selected indicator substances and the formation of transformation products), (2) ecotoxicological parameters (the assessment of ecotoxicity using in vitro tests), and (3) microbiological […]
Soil is an essential component of terrestrial ecosystems and fulfils many important functions being the natural basis of life, habitat, an integral part of water and nutrient cycling, and having a filter function for the protection of groundwater. Earthworms contribute very effectively to the breakdown of organic matter in soil
For in situ remediation of groundwater contaminated by halogenated hydrocarbons Carbo-Iron®, a composite of microscale activated carbon and nano Fe0, was developed. Against the background of the intended release of Carbo-Iron into the environment in concentrations in the g/L-range, potential ecotoxicological consequences were evaluated in the present study
The 7th SETAC World Congress / 37th SETAC North America Annual Conference takes place in Orlando, USA, from 06 to 10 November 2016. ECT is contributing with the following presentations:
J. Römbke: Effects of chemicals on soil organisms in the field: available methods and ecological background
ECT contributes to the 5th EUROSOIL Congress (Istanbul, Turkey, 16-21 October 2016):
J. Römbke, J.-J. Ortega-Calvo, J. Harmsen, J.R. Parsons, K.T. Semple: From bioavailability science to regulation of organic chemicals – the role of biological methods. (Platform presentation)
Residues of veterinary pharmaceuticals enter the environment via application of manure onto agricultural land, where particularly antibiotics can cause phytotoxicity. Terrestrial plant tests according to OECD test guideline 208 are part of the environmental risk assessment of veterinary pharmaceuticals. However, this standard approach might not be appropriate for veterinary medicinal products forming non-extractable residues or transformation products in manure and manure-amended soil. To assess such products, a new test design including a more realistic exposure scenario via manure application is needed.
ECT Oekotoxikologie GmbH is a privately owned enterprise that was founded in 1993.
In compliance with Good Laboratory Practice (GLP), we perform standardised ecotoxicological tests in the laboratory as well as at semi-field and field level.
