New publication: Survival, reproduction, growth, and parasite resistance of aquatic organisms exposed to wastewater treated by advanced treatment processes

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 […]

Report published on ‘Assessment of environmental persistence’

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, […]

New publication: Integrated evaluation concept to assess the efficacy of advanced wastewater treatment processes

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 […]

First complete species list and Red List of earthworms in Germany

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

New publication: Effects of oxidized Carbo-Iron on the amphipod Hyalella azteca

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
