PhD scholarship in soil microbial ecology within the ARISTO project

EFSA identified the monitoring of soil microorganisms as relevant for pesticides environmental risk assessment and stressed the need for novel tests to assess the toxicity of pesticides to soil microorganisms. This issue is addressed by the ARISTO project, the European industry-academia network for revising and advancing the assessment of the soil microbial toxicity of pesticides. […]

Technical proficiency study for OECD 229 successfully completed – capacity for fish short-term reproduction assays available in 2021

The fish short-term reproduction assay according to OECD test guideline 229 serves as Level 3 in vivo assay within the OECD Conceptual framework for the testing and assessment of endocrine disrupting chemicals. Laboratories aiming to conduct this assay must demonstrate their ability by performing a technical proficiency study with reference compounds. ECT has successfully completed […]

Report published on adaptations for a harmonized field-testing procedure and risk assessment of earthworms

A project funded by the German Environment Agency was performed to provide scientifically robust and practical information on the variability of the endpoints assessed in earthworm field studies, the statistical significance of the results and the level of the statistically detectable effects of the chemicals tested with the aim of developing suggestions for improving the […]

New publication: Toxicity of carbendazim to earthworms under tropical and temperate conditions

Research on potential side-effects of pesticides on beneficial organisms has focused on temperate test species and conditions. Thus, there is a need for ecotoxicity studies for pesticides under tropical conditions. The present study aimed to compare the acute and chronic toxicity of the fungicide carbendazim to the earthworm Eisenia fetida under tropical and temperate conditions. […]

ECT remains operative during COVID-19 pandemic

ECT remains to be open and operative during the current COVID-19 pandemic. We take thorough precautions to avoid any health impact and risks for ECT employees, meaning the increase of remote work options and practicing social distancing where remote work is not possible. Access to our facilities is strongly restricted and any business travelling on […]

ECT contributes to the SETAC SciCon

In view of the current situation due to Covid-19, the SETAC Europe 30th annual meeting will take place as a virtual meeting (SETAC SciCon). ECT Oekotoxikologie as SETAC Europe partner is contributing to the scientific programme of the SETAC SciCon: In the ‘Soil ecotoxicology’ session, Jörg Römbke is co-author of a talk presented by Kees […]

New publication: Development of a test method for transformation of pharmaceuticals and biocides in manure

Spreading of manure on agricultural soils represents an important pathway by which veterinary medicinal and biocidal products enter the environment. To assess their environmental impact in the context of authorisation processes, experimental testing of transformation of these compounds in manure is considered in regulatory guidance documents. However, there is no standardised experimental test method available […]

New publication on microbial functional standards for soil quality assessment

The activity of microorganisms in soil is important for a robust functioning of soil and related ecosystem services. There is a necessity to identify the composition, diversity, and function of the soil microbiome to evaluate its properties and functioning and to assess ecotoxicological effects due to anthropogenic activities. Although numerous microbiological methods exist or are […]

New publication: Effects of waste materials on Caenorhabditis elegans

The ecotoxicological characterisation of waste according to the European Waste List (HP14) is part of its hazard classification, which is based on 15 different hazardous properties and should include toxicity tests representing the aquatic and terrestrial compartment. Besides established soil toxicity tests with bacteria, plants, and earthworms, the standardised test with the nematode Caenorhabditis elegans […]
