The persistence assessment under REACH relies on compartment‐specific degradation half‐lives derived from laboratory simulation studies with surface water, aquatic sediment or soil. Although these data are given priority, they are not available for most of the compounds. Therefore, according to the integrated assessment and testing strategy for persistence assessment, results from ready biodegradability tests are […]
A literature study was performed to review the applicability of established and new tests for biodegradability for assessing persistence in the frame of PBT and vPvB assessments under REACH. Screening tests for ready and inherent biodegradability, proposals for enhanced ready tests as well as newly designed compartment-specific screening tests were analysed for strengths and weaknesses, […]

J. Römbke: The bait-lamina test – a newly standardised functional method in soil ecology
The environmental fate of a compound is determined by transformation and distribution processes, which are strongly dependent on the specific environmental conditions. Biodegradability of chemicals in different environmental compartments is one of the major determinants of their environmental fate and therefore plays a crucial role in regulatory decision-making. Simulation studies according to OECD 308 (aquatic […]
Avermectin and milbemycin parasiticides have a high toxicity to non-target organisms, are often persistent and may have a potential to bioaccumulate. The present project contributes to filling gaps in the database for a complete environmental risk assessment of these parasiticides. In addition, risk management strategies for parasiticides used in pasture animals were discussed. For ivermectin […]
Persistent, bioaccumulative and toxic (PBT) compounds deserve specific attention when considering the hazard, which these substances might cause to the environment. These circumstances are taken into account by the European Union in the REACH regulation. For example, for persistent compounds it is difficult to predict long-term effects by established risk assessment procedures, since low degradation […]
ECT Oekotoxikologie GmbH was founded as a privately owned, independent enterprise in 1993, and joined the SynTech Research Group in November 2021.
In compliance with Good Laboratory Practice (GLP), we perform standardised ecotoxicological tests in the laboratory as well as at semi-field and field level.
