ReFoPlan: “Investigation of the effect of adsorbing components that are difficult to degrade of detergents and cleaning agents (WRM) on sediment organisms - polymers" Many detergents and cleaning agents (WRM) contain organic sweeteners that are difficult to biodegrade whose environmental behavior is not yet fully known. These substances include polycarboxylates (PCA), some of their alternatives (PCA alternatives), as well as polyvinyl alcohols (PVA) and polyquaternium compounds (PQ), which are also... Can adsorb activated sludge, sediment and suspended matter. The representatives of these substance classes contained in WRM are largely used in WRM products that can be used for wastewater. And although high elimination rates are sometimes achieved in the sewage treatment plants These can reach surface waters through the constant use of WRM and thus a constant inflow via the wastewater treatment plant processes. There they come into contact with the sediments or suspended particles in the water, causing aquatic and sediment-dwelling organisms can be exposed to the PCA/PCA alternatives, PVA as well as PQ. However, the effect of the adsorbed polymers, particularly on sediment organisms, has hardly been investigated so far. In this research project, the aim is therefore to: Effects of a total of two selected representatives from these substance classes on representatives of the macrozoobenthos in a reconstituted sediment-water system will be examined. The representatives to be examined should carry out preliminary research physical-chemical and ecotoxicological properties and their analysis options from environmental samples at the substance level are selected for each PCA/PCA alternatives, PVA and PQ according to environmentally relevant criteria. After subsequent investigations With regard to their distribution in the artificial sediment-water system, tests with Lumbriculus variegatus and Chironomus riparius should be carried out in accordance with OECD test guidelines ...
