Sammanfattning : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. LÄS MER
Sammanfattning : Electroremediation was applied to contaminated soils in order to study the transport of metals and organic compounds by the external electric field. The electric field caused acidic conditions near the anode, so that copper, zinc, lead, nickel, cadmium, calcium and manganese were released from soil from a chlor-alkali site. LÄS MER
3. Impact of root and mycorrhizal exudation on soil carbon fluxes : influence of elevated CO2 and metals
Sammanfattning : The thesis concerns the behavior of root and ectomycorrhizal (ECM) exudates. In particular, the dynamics of soluble low molecular weight (LMW) organic compounds such as organic acids (LMWOAs), amino acids, monosaccharides, and dissolved organic carbon (DOC) have been studied.

4. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil
Sammanfattning : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. LÄS MER
Sammanfattning : Soil washing of heavy metal contaminated soil may be enhanced by the addition of synthetic chelators. Since many of these chelators may imply stress to soil organisms and are poorly biodegraded, identification and evaluation of effective biodegradable or recyclable chelators (synthetic and/or naturally produced) is of great interest.
