  1. 1. The role of bed sediments for sorption of phosphorus in remediated ditches in Sweden

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Linus Holgersson; [2022]
    Nyckelord :Phosphorus; Two-stage ditch; Equilibrium phosphate concentration; Phosphorus retention; Eutrophication; Soluble reactive phosphorus;

    Sammanfattning : Human activities have increased nutrient losses to agricultural ditches and streams, including phosphorus. Phosphorus leakage leads to a worsening of water quality in downstream ecosystems, including lakes and seas. In addition, higher phosphorus concentrations lead to eutrophication, which negatively affects aquatic systems. LÄS MER

  3. 2. Evaluation of degree of phosphorus saturation (DPS) and easily soluble P in top- and subsoil as a predictor for P-leaching

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jessie Torpner; [2019]
    Nyckelord :degree of phosphorus saturation; dissolved reactive phosphorus; easily soluble P; column experiment; lactate extracted P;

    Sammanfattning : Eutrophication has long been an environmental problem and the effects from fertilizingarable land is a known source. The degree of phosphorus saturation (DPS)and easily soluble phosphorus (P) are different variables used in different countriesto try to predict the leaching of P from soils. LÄS MER

  4. 3. Inhibition of phosphorus release from sediments of Lake Erhai through argon oxygen decarburisation slag (AOD) and electric arc furnace slag (EAF) capping.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Linda Lindholm; [2016]
    Nyckelord :;

    Sammanfattning : The effects of eutrophication in lakes and the open seas has been largely the result of phosphorus (P) that accumulate in the sediment. Eutrophication occurs mainly in the waters in densely populated coastal areas and agricultural dominated areas and occurs when an excess of nutrients reach the soil and water. LÄS MER

  5. 4. Water movement and phosphorus leaching from managed and unmanaged grass buffer strips

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Daniel Jack; [2016]
    Nyckelord :dissolved reactive phosphorus; hydraulic conductivity; organic matter; rainfall simulation; turbidity;

    Sammanfattning : This study was undertaken in a long term field trial investigating the effect of grass buffer strips on nutrient leaching. The treatments included were harvested grass (HG), non-harvested permanent grass (PG) and cultivated soil without a buffer strip (control). LÄS MER

  7. 5. Removal and Recycling of Phosphorus from Wastewater Using Reactive Filter Material Polonite®

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Anna Österberg; [2012]
    Nyckelord :Phosphorus; Polonite®; adsorption; filter; removal; recycling; recovery; wastewater treatment;

    Sammanfattning : Literature reviews and laboratory work were used to examine the phosphorus removal efficiency of the reactive filter material Polonite®. This material is produced from the calcium carbonate and silica based rock Opoka. LÄS MER
