1. 6. Filter Materials for Sorption of Cu and Zn in Stormwater Treatment: A Batch Equilibrium and Kinetic study

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Arkitektur och vatten

   Författare :Per-Albin Norman; [2018]
   Nyckelord :Stormwater; Treatment; Metals; Sorbents; Batch equilibrium test; Isotherms; Kinetic test; Catch basin inserts;

   Sammanfattning : Urban stormwater is today recognized as a significant source of pollution that has contributed to the deterioration of water quality in lakes and streams. Of the pollutants, metals are commonly occurring in stormwater and can cause major damage when released into the receiving waters. LÄS MER

3. 7. A lab study of an iron-coated biochar as a phosphate mitigation tool

   Kandidat-uppsats, SLU/Department of Molecular Sciences

   Författare :Robert Almqvist; [2017]
   Nyckelord :biochar; phosphate; iron; magnetite; nutrient leaching; eutrophication; mitigation;

   Sammanfattning : Nutrients in leachate water resulting from manmade activities are recognized as a major problem leading to eutrophication worldwide. In Sweden and other Baltic countries, agricultural activities are a big contributor to eutrophication of the Baltic Sea. LÄS MER

4. 8. Geochemical processes in mine waste subjected to a changing chemical environment: Fe speciation in leachate water from column experiments

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :Paula Lundberg; [2017]
   Nyckelord :Sulfidic mine waste; Sulfide oxidation; Water quality; Environmental analytical chemistry; Iron redox speciation;

   Sammanfattning : Oxidation of sulfidic mine waste is of significant environmental concern due to the consequent formation of acid rock drainage (ARD), deteriorating the water quality of natural water systems. Iron (Fe) and sulfur (S) are two major redox elements involved in these reactions and typically the major redox-sensitive elements (whose solubility, speciation, and mobility are affected by pH and Eh) in water affected by ARD.

5. 9. Restriction of manure application on high phosphorus soils - Is current research supporting a restriction and what measures are in effect in different European countries?

   Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Oscar Hassby; [2016]
   Nyckelord :Manure; agriculture; phosphorus; leaching; lysimeter; column; manure legislation; meta-analysis; Earth and Environmental Sciences;

   Sammanfattning : The Swedish Water Authorities have proposed a measure to reduce phosphorus losses by restricting manure application on soils with high levels of plant available phosphorus. The aim of this thesis was to investigate if leaching of phosphorus will decrease if the measure is implemented, if the effect is restricted to soils with high phosphorus content and if other European countries have implemented similar measures.

7. 10. Slagg från ArcFume-processer : lakbarhet och återvinningsmöjlighete

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

   Författare :Sara Maier; [2015]
   Nyckelord :slag; leaching; metals; metallurgy; waste; recycling; slagg; laktest; avfall; återvinning; metaller; metallurgi;

   Sammanfattning : Metaller som bryts och utvinns primärt förekommer tillsammans med många andra metaller i malmer och mineral. Avfallsströmmar från metallindustrin har därför ett varierat innehåll av många olika metaller. LÄS MER
