1. Baltic Sea sediments : Source and sink for metal contamination
Sammanfattning : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. LÄS MER
2. Biological Treatment of Oily Sludge and Sediments
Sammanfattning : AbstractOily sludge, generated in refineries or in other industrial sectors, and oil-containing sediments, removed from water bodies during remediation works, pose an environmental problem. A common feature between both is their high water content, and variable content of organic and inorganic contaminants, which complicates their treatment. LÄS MER

4. Sustainable management of dredged sediments : potential recovery of valuable compounds
Sammanfattning : Dredging of sediments occurs worldwide to increase water depth in harbours, bays, lakes and rivers, as well as to recover aquatic ecosystems. Landfilling and open-ocean discharge are traditional disposal routes for dredged material. However, the methods are restricted by environmental and legal concerns. LÄS MER
5. The character of magnetic records of deformed soft sediments with emphasis on liquefaction structures
Sammanfattning : In this thesis the characteristics of magnetic records in deformed soft sediments during postglacial time in Sweden are studied. Magnetic records refer in this study to magnetic remanence (NRM and ChRM) and susceptibility, including its anisotropy (AMS). LÄS MER
