1. Low Molecular Weight Organic Acids and Their Aluminium Complexes in Forest Soils
Sammanfattning : The significance of low molecular weight (LMW) organic acids and their aluminium (Al) complexes in soil solutions of podzolized soils was examined. Methods for the analysis of these compounds and complexes were developed, and the impact of these substances on the weathering and podzolization processes was studied. LÄS MER
2. Organic acids and siderophores in forest soil solution
Sammanfattning : .... LÄS MER
3. Capillary zone electrophoresis for the analysis of low molecular weight organic acids in environmental systems
Sammanfattning : Capillary zone electrophoretic (CZE) methods were developed to identify and quantify low molecular weight (LMW) organic acids in environmental samples. Sensitivity and selectivity were optimised by adapting the background electrolyte to the characteristics of analytes, and by using different modes of detection and injection. LÄS MER
4. Characterisation of organic materials from incineration residues
Sammanfattning : The organic material present in incineration residues has been examined. Water leachable organic material was characterised and classified into hydrophilic and hydrophobic acids, neutrals and bases. Changes of the organic material during weathering were followed. LÄS MER
5. Bacterial use of allochthonous organic carbon for respiration and growth in boreal freshwater systems
Sammanfattning : Aquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere.
