- Master-uppsats, SLU/Dept. of Soil and Environment
Sammanfattning : Micro- and nanoplastics are increasingly perceived as an emerging threat to ecosystems. They are emitted to soils through different pathways, including sewage sludge or compost applications in agriculture, or through tire abrasion and degradation of mismanaged waste. LÄS MER
2. Evaluation of degree of phosphorus saturation (DPS) and easily soluble P in top- and subsoil as a predictor for P-leachingUppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper
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
3. Filter Materials for Sorption of Cu and Zn in Stormwater Treatment: A Batch Equilibrium and Kinetic studyUppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Arkitektur och vatten
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
- Kandidat-uppsats, SLU/Department of Molecular Sciences
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
5. Geochemical processes in mine waste subjected to a changing chemical environment: Fe speciation in leachate water from column experimentsUppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik
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.
