1. Preliminary Investigation into Quantitation of Pharmaceuticals in Lake Victoria Sediments : Development of a Method for Analysis of 11 Pharmaceuticals
University essay from Linköpings universitet/Tema MiljöförändringAbstract : Although Lake Victoria is threatened by pollution there is a lack of knowledge about pharmaceuticals contaminants drained into the lake from large cities bordering the lake. Hence, the purpose of this project was to develop, validate and apply a method for analysis of pharmaceutical compounds accumulating in the Lake Victoria sediments. READ MORE

2. Odensjön - A new varved lake sediment record from southern Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : Annually laminated (varved) sediments provide opportunities to reconstruct climate change and human impact on the environment with high temporal resolution. Depending on the character of the varves, such sediments can provide insight into the delivery of both autochthonous and allochthonous material from the lake and its catch- ment and answer questions regarding both regional and local responses to climate- and land-use changes.

3. The potential disturbance of the 210Pb profile in peat cores by roots and the implications for 210Pb dating.
University essay fromAbstract : At this moment there is a gap in information regarding the affect roots might have on 210Pb distribution in peat cores and in turn the obtained chronologies by 210Pb dating. Therefore, four peat cores were collected from the snow manipulation study site within the mire complex Storflaket (68°20048″N, 18°58016″E). READ MORE

4. Dating lake bottom sediment by searching for 210Pb using gamma-ray spectroscopy
University essay from Uppsala universitet/Tillämpad kärnfysikAbstract : In a collaboration with limnologists at Uppsala University a planar HPGe detector has been used to find 210Pb in lake bottom sediment in hopes of getting an estimation for the sedimentation rate. Using a least squares fit to the data, the sedimentation rate was calculated to 0.08 ± 0. READ MORE
