The Committee for Natural Sciences at Stockholm University has awarded the 2020 Sigrid Arrhenius Scholarship to Malte Posselt, 32, former PhD student at the Department of Environmental Science. Posselt defended his thesis entitled “Transformation of Micropollutants in the Hyporheic Zone” on April 27 this year. In his work, Malte Posselt used advanced analytical techniques together with lab and field based experiments to characterize factors that control chemical degradation in rivers with a specific focus on water-sediment interactions. The findings contribute new knowledge and tools for more effective conservation measures, and increase our understanding of rivers’ self-cleaning capacity with potential consequences for drinking water resources.

The Sigrid Arrhenius Scholarship is awarded to research students for their outstanding work leading up to a doctorate degree. The scholarship recipient receives SEK 45,000 (€4,200).
