1. Molecular analysis of lake-sediment organic matter : long-term dynamics and environmental implications in boreal lakes
Abstract : Lake sediment organic matter is material composed of residues from plants, algae, animals, fungi and bacteria. Its molecular composition is dependent on the sources as well as secondary biotic and abiotic transformations, which combined generates a highly complex matrix. READ MORE

2. Export and sources of organic carbon in the Lena River basin, Northeastern Siberia
Abstract : Permafrost areas are considered to be one of the largest terrestrial storages of carbon. In a warming climate these areas are expected to experience changes in carbon transport to rivers and the oceans due to permafrost thawing, which could enhance erosion, change water flow pathways and increase greenhouse gas emissions.

3. Chlorine Transport in a Small Catchment
Abstract : De senaste decenniernas forskning har påvisat att en omfattande bildning och nedbrytning av klororganiska föreningar sker i mark. Bildning av sådana föreningar sker genom att klorid binds in i organiskt material. READ MORE

4. Chlorine Cycling in Terrestrial Environments
Abstract : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. READ MORE

5. Effects of inorganic nitrogen and organic carbon on pelagic food webs in boreal lakes
Abstract : Anthropogenic activities are increasing inorganic nitrogen (N) loadings to lakes in the northern hemisphere. In many boreal lakes phytoplankton are N limited, wherefore enhanced N input may affect the productivity of pelagic food webs. READ MORE
