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.

Ecotoxicological risks in small streams are high

A comprehensive monitoring study in small Swiss streams shows that these are often heavily contaminated with plant protection products. The ecotoxicological risk due to the pollutant mixtures was high at four of the five examined sites and the water quality therefore considered to be bad. Due to the long-term exposure, there were no time for recovery for the water organisms.
