Abstract [en]

The quantity of pharmaceuticals that end up in aquatic and terrestrial ecosystems are increasing due to a global increase in usage and poor removal efficiency of pharmaceuticals in sewage treatment plants (STP). These compounds may cause great effects on both aquatic and terrestrial ecosystems. Pharmaceuticals are biologically active compounds that may affect non-target organisms. This report focused primarily on if and how the density of Chironomidae (nonbiting midges), Isopoda, Trichoptera (caddisfly) and Simuliidae (black fly) changed when sewage water was treated with ozonation in the river Knivsta, south of Uppsala. Invertebrates were sampled using the kick-sampling method at 6 sites downstream a STP both before and during ozonation treatment. Furthermore, the biodiversity of invertebrates before and after treatment was studied. Significant differences between densities of Isopoda and Gastropoda were found when comparing samples collected before and during ozonation. Both groups were more abundant during ozonation treatment than before. No trend could be found for effects on biodiversity. Further studies are needed to determine which effects pharmaceuticals have on non-target organisms and also if pharmaceutical removal techniques such as ozonation may have other effects, not related to the removal of pharmaceuticals, on ecosystems and the wildlife therein.
