Technical proficiency study for OECD 229 with fathead minnowsK. Duis

Technical proficiency study for OECD 229 successfully completed – capacity for fish short-term reproduction assays available in 2021 and 2022

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 […]

Global data on earthworm abundance, biomass, diversity and corresponding environmental propertiesD. Leib

Publication on global data on earthworm abundance, biomass and diversity

Data collected by ECT in the frame of various research projects in the last decades contributed to a publication on the global abundance and diversity of earthworms. Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large […]

Prioritisation and risk evaluation of medicines in the environment (PREMIER)Premier

New project started: ‘Prioritisation and risk evaluation of medicines in the environment’ (PREMIER)

The Innovative Medicines Initiative (IMI) project PREMIER aims to develop a centralised, user-friendly digital assessment system accessible for all relevant stakeholders. PREMIER will also explore options to incorporate environment considerations earlier in the drug development process to inform drug design and to reduce the need of animal testing. ECT is involved in this project as […]

Environemtal fate and effects of water-soluble polymersK. Duis

Review on the environmental fate and effects of water-soluble synthetic organic polymers

Because of their usually high molecular weight, polymers are generally considered as being of low environmental concern and are, therefore, exempted from registration and evaluation within REACH. This exemption is currently being reviewed by the European Commission. Against this background, data on the environmental fate and effects of selected water-soluble synthetic organic polymers used in […]

An adapted test design for earthworm field studies was developed combining a NOEC and ECx approach and a pilot field study was performed.ECT Oekotoxikologie GmbH

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. […]

Transformation of veterinary pharmaceuticals and biocides in manureT. Junker

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 […]
