Rewetted degraded fen peatland site

New publication: Dissipation of micropollutants in a rewetted fen peatland – a field study using treated wastewater

A mixture of treated wastewater and surface water was used to rewet a degraded fen peatland site during a three-year rewetting experiment. Behaviour and effects of micropollutants were studied using hydrological, physico-chemical, microbiological and ecotoxicological monitoring. The highest concentrations of micropollutants in the treated wastewater were found for the pharmaceuticals carbamazepine and diclofenac, some metabolites, […]

Review of the effects of organic pesticides on enchytraeids (Oligochaeta) in agroecosystems – laboratory and higher-tier tests

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 […]

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 […]

Efficacy of advanced wastewater treatment

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 […]

Joint effects of pharmaceuticals and industrial chemicals from wastewater treatment plant effluents – evaluating concepts for a risk assessment using experimental scenarios

The aim of this project is to develop and evaluate concepts for a risk assessment of waste water effluents taking into account the joint effects of chemicals that are not completely eliminated in the wastewater treatment process. The focus is on pharmaceutical residues and industrial chemicals, particularly those that are frequently detected in effluents. The […]
