Ecosystem stress caused by micropollutants

Micropollutants enter rivers and streams in effluents discharged from wastewater treatment plants (WWTPs). As well as having adverse impacts on individual species, these substances appear to alter aquatic ecosystem functions, such as litter decomposition. This was shown by a research project launched by Eawag in view of the planned upgrade of selected Swiss WWTPs to reduce micropollutant loads. The effects of the first upgrades are already evident.
