Subject of research

Research Activities
Beside fundamental investigations on the transport, transformation and retention of substances in low-temperature systems, the main emphasis of the Applied Geochemistry group is focussed on environmental problems. This includes the quantification of element fluxes and identification of contamination levels in soil, water, sediment and air. Methods and techniques to determine accurate fluxes of trace substances had evolved significantly within the last years and contamination sources can be identified by element fingerprints or isotope signatures. The Applied Geochemistry group collaborates with industry partners to develop such innovative methods and techniques and assess these products for the applications in natural systems. Current research activities include:
- Calcite application for the restoration of eutrophic lakes
- Assessment of an ultramicroelectrode array sensor for the determination of trace  concentrations of heavy metals in water
- Mobilisation and transport of arsenic in groundwater of West-Bengal
- Development of filter systems to improve the quality of heavy metal contaminated drinking water in rural areas of Ethiopia and Indonesia
- Development of a water quality monitoring system for sustainable water management in coastal urban areas in China
- Fixation of heavy metal during Fe-sulfide formation in estuarine environments
- Water/rock interactions in underground rivers as a contribution to develop an integrative water resource management in the karst areas of Java, Indonesia
- Paleo-reconstruction of extreme river floods in Germany
