1. 1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Johanna Bergström; [2023-09-15]
   Keywords : Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

   Abstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE

3. 2. Evaluation of in-situ technology performance and decision analysis by combining economic and environmental impact analysis for a case study

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Elham Tamadonyazdian; [2023]
   Keywords : Stabilization; Dredging; Solidification; Cement mixtures; Binders; In-situ technology; Environmental impact categories; Life cycle assessment LCA ; Economic analysis; Life cycle costing LCC ; Global Warming Potential GWP ; Acidification Potential AP ; Eutrophication Potential EP ; Ozone Layer Depletion Potential ODP ; Single-Point Rate SPR .; Technology and Engineering;

   Abstract : In the contemporary global context, the global focus on reducing environmental impacts in any formats has intensified. This study intends to assess the environmental impacts and life cycle costs associated with the A1-A5 stages (production and construction stages) of the Köping Port project and eight additional proposed scenarios.

4. 3. Separation and acidification of digested animal manure : properties of the future organic fertilizers

   University essay from SLU/Dept. of Soil and Environment

   Author : Marie Björs; [2023]
   Keywords : Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

   Abstract : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. READ MORE

5. 4. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Ann-Kathrin Wild; [2022]
   Keywords : trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

   Abstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.

6. 5. Stadens biologiska mångfald : ett urbant grönområdes ekosystempåverkan ur ett livscykelperspektiv

   University essay from SLU/Dept. of Energy and Technology

   Author : Linnéa Sigvardsson; Molly Lind Mayer; [2022]
   Keywords : Livscykelanalys LCA ; biologisk mångfald; grönområde; urbana grönområden;

   Abstract : Gröna stadsområden utgör en ekonomisk och social samlingspunkt. Fragmentering av grönområden är ett av de största hoten mot biologisk mångfald. Nästan 60% av alla grönområden i Sverige består av klippta gräsmattor som inte kan nyttjas av många arter. READ MORE
