6. Characterisation of natural dissolved organic matter with liquid chromatography and high resolution mass spectrometry
Abstract : Dissolved organic matter (DOM) is one of the most heterogeneous and complex mixture on Earth. DOM plays a crucial role in biogeochemical processes on the global scale and it is essential to sustain and regulate the biological processes in aquatic ecosystems. READ MORE

7. 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

8. Compositional clues to sources and sinks of terrestrial organic matter transported to the Eurasian Arctic shelf
Abstract : The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. READ MORE

9. Photochemical alterations of dissolved organic matter : Impact on heterotrophic bacteria and carbon cycling in lakes
Abstract : Globally, the amount of carbon in dissolved organic matter (DOM) is similar to the total amount in the atmosphere. DOM also plays a key role in structuring natural surface waters and affects the physical, chemical, and biological character of these systems. READ MORE

10. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites
Abstract : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. READ MORE
