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.

Mobile system measures water quality in real time

June 10, 2020
Thanks to a new instrument, water pollutants can be measured automatically over a period of weeks – directly in the field, rather than in the laboratory. The mobile mass spectrometer is housed in a trailer and can be remotely controlled by smartphone. read more
