1. Nitrogen Cycling at Cold Climate Mine Sites in Northen Sweden
Abstract : High nitrogen discharge from mining sites has been an environmental issue that has been closely studied in the recent years. The environmental effects of high nitrogen discharge are mainly eutrophication, but can also lead to changed species composition and algae blooms. READ MORE

2. Suspended particulate matter, sedimentation and early diagenetic processes in the Kalix River estuary, northern Sweden
Abstract : Many important reactions controlling the transfer of elements from the continents to coastal waters and the oceans are taking place in estuaries. For many elements, estuaries can act as filters, capable of reducing the river load of dissolved and particulate elements to the oceans. READ MORE

3. Nitrogen-cycling tracing methods : Case studies at cold-climate mine sites in northern Sweden
Abstract : High nitrogen effluents from mine sites is an environmental issue which has received relatively little attention historically. In recent years a number of studies have showed the environmental effects of high nitrogen discharge to natural water bodies, which include local eutrophication, high risk of acute reducing conditions and changed species composition in the receiving waters.

4. Pit lake water quality and hydrology : Insights from case studies and modelling of pit lakes in northern Sweden
Abstract : As extraction techniques are improving an increased number of low grade deposits can be economically mined. However, this also means that the number of open pit mines will increase and as a result the number of pit lakes as well. READ MORE

5. Isotope Ratio and Trace Element Measurements Using Inductively Coupled Plasma – Mass Spectrometry : Method Development and Applications in Environmental Forensics
Abstract : Environmental Forensics is a scientific methodology developed for identifying sources, the timing of release, and transport pathways for potentially hazardous environmental contaminants. It combines a variety of analytical methods with principles derived from disciplines such as chemistry, geology, geochemistry, hydrogeology, and statistics, with the purpose to provide objective scientific and legal conclusions on the source and/or time of a contaminant release.
