Soil-water interactions, fate and flux of dissolved organic matter and key elements
Biogeochemical processes govern leaching and transport of chemicals in the environment. In the boreal domain the natural dissolved organic matter (humus) play a central role in practically all of these reactions. These mechanisms are changing due to changes in pressures, such as climate, causing a change in the state of environment and effect on biota.
We focus on mechanisms governing the transport of chemical compounds from soil, to fresh water and through watercourses. More specifically, we conduct research on the effects of climate change on water quality by assessing mobility, transport and effect of heavy metals, POPs and nutrients.
Our research is interdisciplinary, using our knowledge of biogeochemistry, chemical fractionation / speciation and statistics with modelling / simulation, in collaboration with other nature and social scientists to generate knowledge for sustainable management of our natural resources. The studies are mainly conducted in China, Central Asia, Eastern Europe and Africa.
