1. A GIS-based landscape analysis of dissolved organic carbon in boreal headwater streams
Abstract : In boreal catchments, stream water chemistry is influenced and controlled by several landscape factors. The influence of spatially distributed variables is in turn dependent on the hydrological scale. READ MORE

2. Landscape hydrogeochemistry of Fe, Mn, S and trace elements (As, Co, Pb) in a boreal stream network
Abstract : The transport of elements by streams from headwater regions to the sea is influenced by landscape characteristics. This thesis focuses on the influence of landscape characteristics (e.g. READ MORE

3. Radionuclide transport in the boreal landscape : Uranium, thorium and other metals in forests, wetlands and streams
Abstract : The boreal landscape is complex mosaic of vast forests, lakes and wetlands. Through the landscape flows a fine network of streams and rivers, carrying dissolved and suspended material from atmospheric deposition and weathering of soils and bedrock to downstream recipients. READ MORE

4. Hydrogeochemistry of Fe and Mn in small boreal catchments
Abstract : It is suggested that the overall understanding of the general hydrogeochemistry of a region is best understood from a landscape perspective. If so, this can provide useful information when planning monitoring programmes and influence of human activity. READ MORE

5. Determination of mercury chemical speciation in the presence of low molecular mass thiols and its importance for mercury methylation
Abstract : Methylmercury (MeHg) is a neurotoxic compound that threatens the well-being of humans and wildlife. It is formed through the methylation of inorganic mercury (HgII) under suboxic/anoxic conditions in soils, sediment and waters. READ MORE
