On the trail of pollutants

Our research team studies the presence, distribution and fate of organic pollutants in the aquatic environment. The focus of our research is on substance flux from urban areas and from agriculture, and the main tools that we use for this work are trace analysis, field and laboratory studies and modelling.

Surprising discovery of pollutants in gammarids

December 3, 2018
Amphipods in Swiss waters are exposed to insecticides, pharmaceutical residues and other trace substances, and accumulate these in their bodies. However, when water-treatment plants are upgraded, practically no trace substances are found in these organisms according to a new study carried out by Eawag researchers.. [more]

Conference will be held from 28. April 19 - 03. May 19 in Monte Verità, Ascona Switzerland.
