1. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. READ MORE

3. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

5. The prospects of using acoustic particle separation techniques to separate heavy metals from lake- and seabed sediments
University essay from KTH/Marcus Wallenberg Laboratoriet MWLAbstract : This work aims to investigate if it is realistic to use acoustic particle separation techniques for separating heavy-metals from pump-dredged seabed sediments on a large scale. A premise for the project has been that the material should undergo hydrothermal carbonization (HTC) before acoustic treatment. READ MORE
