  1. 1. Brownification in a small stream originating from a peatland - A case study from Ryds Å in south Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Emelie Ström; Frida Karlsson Öhman; [2024]
    Keywords : Brownification; Peatland; Bolmen; DOM; Water Quality; Inflow; Technology and Engineering;

    Abstract : Brunifiering syftar till en process där vattnet blir brunare på grund av ökade halter av naturligt organiskt material och järn, vilket innebär utmaningar för miljön och människor. Sjön Bolmen i södra Sverige har problem med brunare vatten. READ MORE

  3. 2. 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

  4. 3. 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.

  5. 4. How brownification and eutrophication effects a drinking water source – with Lake Bolmen, Sweden, in focus

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Stina Stomberg; [2022]
    Keywords : brownification; eutrophication effects; drinking water; phytoplankton; Lake Bolmen; mesocosm; Earth and Environmental Sciences;

    Abstract : The ongoing human impact in form of deforestation, urbanization and intense agriculture is affecting the natural hydrology and our freshwater lakes negatively. Both eutrophication and brownification has seen to increase with the ongoing environmental change which can potentially have large impact on our freshwater ecosystems. READ MORE

  6. 5. Wetlands both reduce and contribute to brownification - a study from Kalmar County, Sweden

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Isabell Fritiofsson; [2021]
    Keywords : DOC; absorbance; Northern Europe; brownification; wetland;

    Abstract : During recent decades the brownification through leaching of organic carbon into Northern hemisphere water bodies has become apparent. This is considered a problem because of the implications it has on ecosystems and freshwater sources used for drinking water. READ MORE
