Research project CHEMPACT - Status of CHEMical emissions via wastewater treatment plant effluents and imPACT

The project compiles and synthesizes data on micropollutants in wastewater emitted in the Baltic Sea drainage basin and reviews effects associated with chemicals in wastewater in the Baltic Sea catchment.

CHEMPACT aims to contribute to minimizing risks for human health and the environment arising from chemicals emitted in the urban areas and transferred to the aquatic environment via WWTPs in the Baltic Sea catchment. We will compile published data on measured concentrations of contaminants in wastewater, analyse and visualize the data and review the literature on associated ecotoxicological effects. We will communicate the results and conclusions to relevant stakeholders.

Please contact Emma Undeman,, if you are interested in the CHEMPACT database.
