1. Dissolved organic matter in lakes : Chemical diversity and continuum of reactivity
Abstract : Dissolved organic matter (DOM) is the largest pool of organic carbon in aquatic systems and an important component of the global carbon cycle. Large amounts of DOM are decomposed within lakes, resulting in fluxes of CO2 and CH4 to the atmosphere. READ MORE

2. Virus Fate and Transport in Groundwater : Organic matter, uncertainty, and cold climate
Abstract : Water managers must balance the need for clean and safe drinking water with ever-increasing amounts of waste-water. A technique for treating and storing surface water called “managed aquifer recharge” (MAR) is frequently used to help maintain this balance. READ MORE

3. Molecular-level dissolved organic matter dynamics in lakes : Constraints on reactivity and persistence
Abstract : Dissolved organic matter (DOM) is a central component of the global carbon cycle. Thus, small changes to the amount of DOM imported, processed and produced within lakes can have a large effect on regional carbon budgets. In addition to being a vital energy source at the base of the aquatic food web, DOM is physico-chemically reactive. READ MORE

4. 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

5. Mineralisation rates of natural organic matter in surface sediments affected by physical forces
Abstract : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. READ MORE
