In recent years the occurence of polar organic micropollutants such as pharmaceuticals in wastewater, surface water, groundwater and finally drinking water has gained more and more attention. A broad spectrum of compounds with different properties can be detected by powerful analytical instrumentation like liquid chromatography coupled with tandem mass spectrometry. High resolution mass spectrometry allows also for detection of unknowns such as transformation products formed from the micropollutants. Adverse effects at environmental concentration levels have been unambiguously shown only for a few micropollutants but the high number of compounds asks for new elimination strategies. Besides prevention strategies at the source additional treatment steps such as ozonation or adsorption at activated carbon within the sewage treatment process are currently investigated. Scope of the presentation is to give an overview about origin and entry of polar micropollutants in the aquatic environment, their environmental behaviour as well as their elimination in sewage treatment plants equipped with different techniques.
