1. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes
Sammanfattning : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. LÄS MER
2. Fate and transport of POPs in the aquatic environment : with focus on contaminated sediments
Sammanfattning : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bioavailability and environmental transport of the POPs. LÄS MER
3. Effects of organic amendments on the biodegradation of petroleum hydrocarbons in contaminated soil
Sammanfattning : .... LÄS MER
4. Role of soil organic matter for immobilisation of metals : treatment of leachate from MSWI bottom ashes
Sammanfattning : In this thesis, the focus is laid on the ability of natural organic matter (OM) to serve as a metal stabilising agent. The metal contaminants investigated arise from the MSWI bottom ash leachate. Besides the high content of metals, elevated pH and salinity are characteristic for ash leachate that, in turn, can alter the functionality of OM. LÄS MER
5. Effects of Bio-Ash Amendments on the Metabolism of Ectomycorrhizal Fungi : A Method Development and Metabolomic Study
Sammanfattning : Forest ecosystems have played a fundamental role in the development of our society. Since the beginning of the civilization, forest have provided us with wood as a product for construction, tools, furniture and domestic heating. The well-being of the forest is therefore fundamental to our existence. LÄS MER
