Description: Objectives: In this study we investigate the reactions of fine roots of spruce and poplar to enhanced heavy metal contents in the soil. Soil cores are sampled once or twice a year and the fine roots sieved or sorted out. Parameters which are measured in the fine roots are heavy metal and other element concentrations, protein concentrations, and the activity of the peroxidases. With in-growth cores we intend to measure growth and architecture of newly derived fine roots. Parallel to these investigations, other groups investigate further fine root features using the microscope or the SEM-EDX. Sampled soils are investigated by soil chemists and microbiologists. The birches were inoculated with a specific strain of the ectomycorrhizal fungus Paxillus involutus. We intend together with other groups to investigate their mycorrhizas in order to localise and quantify the heavy metals on a subcellular level using STEM-EDX.
