The effects of biochar on immobilizing Pb, Zn, Cu and Cd in contaminated soils from the mining sites in Kabwe (Zambia) and Folldal (Norway)
Brandsvoll, Cecilie (Master thesis, 2021)Mining activities and resulting waste products are among the main sources of severe heavy metal pollution in the world. This study aims to examine i) the level of soil contamination, ii) mobility and ii) bioavailability ... -
Geochemistry and availability of barium (Ba) to plants grown in soils with ordinary and Ba-enriched mineralogy
Myrvang, Mona Bakke (PhD Thesis;2016:71, Doctoral thesis, 2016)In recent years there has been an increasing interest for the use of crushed minerals and rocks as soil amendment and slow-release fertilizers in agriculture. Apatite-biotite-carbonatite (short form: carbonatite) rock from ... -
Separation and quantification of microplastics from beach and sediment samples using the Bauta microplastic-sediment separator
Mahat, Sabnam (Master thesis, 2017)Microplastic pollution is a topic of scientific interest globally. The environmental impacts caused by microplastics have spurred research focusing on separation and quantification of microplastics from soil and sediments ... -
Temporal changes in plant available phosphorus in a long term experiment growing winter wheat (Triticum aestivum) on Rothamsted, England
Kvifte, Åsmund Mikalsen (Master thesis, 2016-08-11)Fosfor er eit næringsstoff naudsynt for alt liv, men det er ein avgrensa ressurs som på avvege kan føra til uynskja algeblømingar. Difor er det viktig med god fosforbruk i landbruket, der det kjem mykje mat frå den tilførde ... -
The partitioning of P in soil determines the fluxes and deliveries of labile P in soil solution
Almås, Åsgeir R.; Sævarsson, Hilmar Thor; Krogstad, Tore (Peer reviewed; Journal article, 2017)Phosphorus (P) is an increasingly limited resource for food production, which necessitates studying soil factors controlling rates of P release to soil solution. Phosphorus use efficiency is among other, affected by the ... -
The partitioning of Sb in contaminated soils after being immobilization by Fe-based amendments is more dynamic compared to Pb
Almås, Åsgeir R.; Pironin, Elsa; Okkenhaug, Gudny (Journal article; Peer reviewed, 2019)Soils and sediments from shooting ranges can be heavily contaminated with metals and metalloids that can leach significant concentrations into the environment. To prevent trace element leaching, contaminated soils must be ... -
The presence of microplastics on the Norwegian Continental Shelf and in Rio Almendares, Havana
Lilleeng, Øyvind (Master thesis, 2018)Microplastics are becoming more frequently detected in all natural environments worldwide as global demand for plastic production continues to rise and studies related to microplastic research are becoming more prevalent. ... -
Trace metal availability in soils under different land uses of the Danube basin in Croatia
Ivezić, Vladimir (PhD Thesis;2011:65, Doctoral thesis, 2011)Soils are non-renewable resource of biological, chemical and physical properties. One of the ecological functions of the soil is its capacity to filter and buffer trace metals. Trace metals can pose a threat on the one ... -
Utprøving av ny metode for kvantifisering av mikroplast i biogjødsel
Dale, Ann-Katrin (Master thesis, 2018)Denne masteroppgaven tar for seg problemstillinger knyttet til analyse av mikroplast i prøver med høyt innhold av organisk materiale. Bioresten fra storskala biogassanlegg benyttes til produksjon av biogjødsel. Biogjødsel ... -
Waste-based sorbents for reducing the mobility and leaching of per- and polyfluoroalkyl substances (PFAS) in contaminated soil
Qvale, Anny (Master thesis, 2021)Per- and polyfluoroalkyl substances (PFAS) are a diverse group of anthropogenic, organic chemicals whose widespread use have caused contamination issues worldwide. Former use of PFAS-containing firefighting foams have ... -
What happens to biodegradable plastics in soil and compost? : development and comparison of methods
Brilke, Andreas (Master thesis, 2020)Plastics in terrestrial ecosystems negatively affect their functioning by altering physical properties and disturbing soil microorganisms. The same could be true for biodegradable plastics entering nature through incomplete ...
