1. Low Molecular Weight Organic Acids and Their Aluminium Complexes in Forest Soils
Abstract : 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. READ MORE

2. Forests and Greenhouse gases. Fluxes of CO2, CH4 and N2O from drained forests on organic soils
Abstract : One of the largest environmental threats believed to be facing us today is global warming due to the accumulation of green house gases (GHG). The concentrations of GHG in the atmosphere are a result of the net strength of different sinks and sources. READ MORE

3. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites
Abstract : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. READ MORE

4. Land use effects on nitrous oxide emission from drained organic soils
Abstract : Since industrialisation, the atmospheric concentration of greenhouse gases (GHG) has increased significantly. The most important anthropogenic GHGs are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). N2O is of major concern for two reasons; i) it is a potent GHG responsible for 6. READ MORE

5. Association of hydrophobic organic compounds to organic material in the soil system
Abstract : Contaminated soils and sediments have been identified as significant secondary sources of organic contaminants. Leaching tests may be useful tools to estimate the mobility of contaminants via the water phase and thereby the risk for groundwater and surface water contamination. READ MORE
