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.

July 8 2019, Without phosphorus there would be no life; however, the mineable quantities are limited. The element was first described 350 years ago. This week, some 200 experts are meeting in Zurich to discuss the future of phosphorus. [more info]

Selected and representative research projects

Comprehensive monitoring of organic trace substances in surface waters is time-consuming and costly. The NAWA SPEZ project delivers data and analyses on the status of water pollution.
Predicting environment-specific biotransformation of chemical contaminants
The screening of aquatic systems for known and unknown polar and semi-polar organic micropollutants relies heavily on analytical chemistry, foremost high-resolution mass spectrometry (HRMS) coupled to liquid chromatography (LC)....
