  1. 1. Dissolved organic matter (DOM) quality in agricultural streams and its impact on carbon dioxide concentrations in stream water

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Broqvist; [2018]
    Keywords : DOM quality; dissolved organic matter; DOC; PARAFAC; fluorescence; streams; agriculture; fluorescence index; freshness index; humification index; carbon dioxide; DOM kvalitet; löst organiskt material; DOC; PARAFAC; fluorescens; bäckar; jordbruk; fluorescence index; freshness index; humification index; koldioxid;

    Abstract : Inland waters have lately been recognized to be an important component in the carbon cycle, having a significant role in carbon sequestration and carbon dioxide (CO2) emissions. Attention has also been drawn to the impact of the quality (i.e. composition and source) of dissolved organic matter (DOM) on CO2 production. READ MORE

  3. 2. Relation between Contemporary Water Chemistry and Historical pH from Paleolimnology to Estimate Reference Conditions in Swedish Lakes : Development of a simple tool for acidification assessment

    University essay from Institutionen för geovetenskaper

    Author : Ivonne González; [2012]
    Keywords : Water Framework Directive; Sustainable Development; Reference Conditions; Good Ecological Status; Paleolimnology; Acidification Assessment;

    Abstract : Abstract: Acidification was categorized as the main environmental problem in Scandinavia during the 1960’s. Fortunately for Sweden, as with other countries in Scandinavia, has shown a process of recovery from acidification, by emission control. Further Sweden has had an extended liming program to mitigate the effects from acidification. READ MORE

  4. 3. Modeling Chloride Retention in Boreal Forest Soils - synergy of input treatments and microbial biomass

    University essay from Tema vatten i natur och samhälle

    Author : Stephen Kayode Oni; [2007]
    Keywords : Biogeochemical model; Chlorine biogeochemistry; Chlorine cycles; Chloride immobilization; Microbial Biomass; Water residence time;

    Abstract : The hypothetical assumption that chloride is conservative in the soil has been debated for the last decade. The results of the recent years of study in chlorine biogeochemistry show that chloride is non-conservative but rather participates in complex biogeochemical reactions in the soil. READ MORE

  5. 4. Modelling Chlorine Transport in Temperate Soils

    University essay from Tema vatten i natur och samhälle

    Author : Olatunde Idris Ibikunle; [2007]
    Keywords : Hydrochemical model; chlorine biogeochemistry; microbial retention and oxygen;

    Abstract : Microbes have been suggested to have a strong impact on the transportation of chlorine in soils. There are speculations about environmental factors limiting microbial effect on chlorine movement and retention. READ MORE
