[Schmidt, Torsten C.] 4209 Moderne Kläranlagen reinigen Abwasser effizient von leicht abbaubaren organischen Stoffen und Nährstoffen. Sie sind aber nicht für die Eliminierung von Mikroschadstoffen konzipiert, so dass viele dieser Stoffe im Abwasser kaum abgebaut werden und somit über die Vorflut in Oberflächengewässer gelangen. Dieser Artikel geht unter anderem der Frage nach, wie überhaupt Auswirkungen von Gemischen unzähliger Verbindungen im niedrigen Konzentrationsbereich auf Organismen messbar sind. 4209 Surface waters can contain a diverse range of organic pollutants, including pesticides, pharmaceuticals and industrial compounds. Effluents from wastewater treatment plants (WWTPs) are known to be point sources of micropollutants for surface waters and are currently under scrutiny for retrofitting with advanced treatment options including ozonation. While bioassays have been used for water quality monitoring, there is still limited knowledge regarding the specific contributions of individual micropollutants to overall observed effects. This is particularly true for ozonation due to the possible formation of transformation and oxidation by-products. To further investigate the use of effect-based methods, a combination of state-of-the-art chemical analysis, in-vivo and in-vitro assays are established at the University of Duisburg- Essen and its affiliated institutes IUTA and IWW. As an example, the effectiveness of a full-scale ozone treatment in combination with a fluidized moving-bed reactor as biological post-treatment for the reduction of many micropollutants without the release of relevant toxic transformation products has been assessed by such a chemical and toxicity-based approach. 4950 https://doi.org/10.17185/duepublico/70362$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:hbz:464-20190809-144726-0$xR$3Volltext$534 4961 https://duepublico2.uni-due.de/receive/duepublico_mods_00070362 5051 570 5051 624
