Welcome to the Institute of Biogeochemistry and Pollutant Dynamics (IBP) at ETH Zurich. It is part of the Department of Environmental Systems Science (D-USYS). On this site you find information about the institute's specific teaching and research activities.



Peat soils as gigantic batteries

Researchers from ETH Zurich and the University of Tubingen describe a process that suppresses the formation of methane in soils that are rich in humic substances. For this process to work, the soils need to switch between having no oxygen and having oxygen.

L Klüpfel, A Piepenbrock, A Kappler, and M Sander. Humic substances as fully regenerable electron acceptors in recurrently anoxic environments. Nature Geoscience 7,195–200(2014). DOI 10.1038/ngeo2084. Media release ETH Zurich: ETH News 28Feb2014.

Emissions of selenium, arsenic and sulfur from wetlands

A new study led by Eawag and ETH researchers shows that emissions of selenium, arsenic and sulfur from wetlands may play an important role in global biogeochemical cycles, and that temperature-dependent release is expected to rise as a consequence of global warming.

Biotransformation research at IBP and Eawag

Kathrin Fenner has been awarded a highly prestigious European Research Council (ERC) Consolidator Grant for her project "PROduCTS – Predicting Environment-Specific Biotransformation of Chemical Contaminants". The 5-year project will work with data mining of existing biotransformation databases and gene expression profiling of microbial communities to foster the environment-specific prediction of rates and products of microbial metabolism.

As pesticides break down in the environment, potentially hazardous transformation products may remain. Science 16 Aug 2013: Vol. 341 no. 6147 pp. 752-758

New Climate Audio Trail in the Swiss Alps

The CCES project cluster BigLink in collaboration with myclimate and Wasserwelten Göschenen has published a new audio trail at Göschener Alp. The stories (in German) can be downloaded as mp3 files, for kids (Mit Andrea und Beat auf Forschungsreise) and adults (Gletscherblüte und Zeitreise). Alternatively, the audio guides can be borrowed for free at the kiosk of the Restaurant Dammagletscher. flyer.pdf, medienmitteilung myclimate.pdf & ETH Life
