1. 1. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Hampus Holmberg; [2023-06-22]
   Keywords : ;

   Abstract : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. 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. 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 geovetenskap

   Author : Anne Rebotzke; [2023]
   Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

   Abstract : 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. 4. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Christina Henricson; [2023]
   Keywords : ;

   Abstract : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. READ MORE

6. 5. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

   University essay from SLU/Dept. of Soil and Environment

   Author : Emma Ryding; [2022]
   Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

   Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE
