Presentation

My research aims to study mercury in soils, water, and biota, and how the transformation and mobilization of mercury is influenced by natural and man-made perturbations. As forestry activities may increase the already high concentrations of mercury in inland fishes, my main research interest is to understand how different forestry activities influence the formation of bioavailable methylmercury and the mobilization of methylmercury from soil to surface waters. By this research we hope to form adequate recommendations for measures to mitigate Hg export in connection with forest harvesting.

Research

Ungoing projects

Mercury in runoff water: Identifying site specific factors and mitigation measures that influences mercury export and methyl-mercury formation at forest harvest. The project is financed by Formas (The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning). Read more about the project here. 

Connectivity between mercury methylation hot-spots and surface waters as a consequence of biofuel harvesting. The project is financed by the Swedish Energy Agency. Read more about the project here.

SMaReF (Sino-Swedish Mercury Management Research Framework) is a research framework that aims at creating research collaboration between Sweden and China about mercury in the environment. Read more about the framework here.

WAMBAF (Water management in Baltic Forests) is an EU founded (European Regional Development Fund) project that aims to reduce nutrient and mercury export from forestry to streams, lakes and the Baltic Sea. The project is led by the Swedish Forestry Agency. Read more about the project here

Increasing DOC concentrations in surface waters and how this influence the share of acidified lakes – a study of extreme weather situations. Is the response of DOC concentrations in water to flow and season different during periods of extreme drought compared to the stable response of flow and season observed during the last three decades? The project is founded by the Swedish Environmental Protection Agency.
