  1. 1. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Osterman; [2023]
    Keywords : Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Abstract : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. READ MORE

  3. 2. Operating procedures and evaluation of a carbon capture pilot plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Isac Logeke; [2023]
    Keywords : Carbon Capture and Storage; CCS; AMP DMSO; amine absorption; pilot plant; operating procedures; chemical engineering; Chemistry;

    Abstract : The rise in global emissions of carbon dioxide and the need for new technologies to combat climate change has prompted extensive research into carbon capture methods. This master thesis focuses on a novel carbon capture absorption technology, developed at Lund University, that utilizes the amine 2-amino-2-methyl-1-propanol (AMP) in the organic solvent dimethyl sulfoxide (DMSO) to capture CO2.

  4. 3. Effects of Forest Ditch Cleaning on Surface Water Quality

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Emeli Arvidsson; [2023]
    Keywords : Ditch cleaning; forest clear-cut; water quality; water chemistry;

    Abstract : Ditch cleaning (DC) is recommended by authorities to Swedish landowners to maintain forest productivity after forest harvest by lowering groundwater tables of catchment soils. Knowledge regarding the impact of this practice on surface water quality is limited, and results from previous research vary. READ MORE

  5. 4. Mercury in a Swedish landscape over 30 years : a thesis on mercury concentrations in different water-cathments in Krycklan and Degerö stormyr

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Ted Pettersson; Isak Haglund; [2023]
    Keywords : Atmospheric deposition; concentrations; dissolved organic carbon; mercury; methylmercury; peatlands; water-catchments;

    Abstract : The purpose of this thesis is to examine trends in concentrations of total mercury (TotHg) and methylmer¬cury (MeHg) in water streams around Vindeln, Sweden, located northwest of Umeå. The relation¬ship between dissolved organic carbon (DOC) and TotHg were also examined in this thesis. READ MORE

  6. 5. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Anna Lackner; [2022]
    Keywords : Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

    Abstract : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.
