1. 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.

2. Interactions between Fe and organic matter and their impact on As(V) and P(V)
Abstract : Iron (Fe) speciation is important for many biogeochemical processes. The high abundance and limited solubility of Fe(III) are responsible for the widespread occurrence of Fe(III) minerals in the environment. READ MORE

3. Iron and aluminium speciation in Swedish freshwaters : Implications for geochemical modelling
Abstract : Speciation governs transport and toxicity of trace metals and is important to monitor in natural waters. Geochemical models that predict speciation are valuable tools for monitoring. They can be used for risk assessments and future scenarios such as termination of liming. READ MORE

4. Climate Change Adaption of Waterworks for Browning Surface Waters : Nano- and Ultrafiltration Membrane Applications for Drinking Water Treatment
Abstract : Natural organic matter (NOM) is found in all surface, ground, and soil waters. During recent decades, reports worldwide show a continuing increase in the color and NOM of the surface water, which has an adverse effect on drinking water purification. For several practical and hygienic reasons, the presence of NOM is undesirable in drinking water. READ MORE

5. Modern Artificial Recharge Plants : Combining chemical flocculation with aquifer recharge
Abstract : Water supply security is increasingly becoming a challenge worldwide. Surface waters, which are often used for drinking water production, have experienced an increase in natural organic matter (NOM) and frequency of algae blooms. Water quantity is also an issue due to increasing populations and potable water demand. READ MORE
