Heavy metal accumulation in trees growing on contaminated sites in Central Europe

Original language description

Metal-accumulating woody species have been considered for phytoextraction of metal-contaminated sites. We investigated Zn and Cd accumulation in tissues of adult trees and associated herbaceous species collected from contaminated areas in Central Europe.We found considerable Cd and Zn accumulation in various willow, poplar and birch species with up to 116 mg Cd kg-1 and 4680 mg Zn kg-1 in leaves of Salix caprea. Annual variation of Cd and Zn were small, indicating that data obtained in different yearscan be compared. Metal concentrations in leaves were not related to total (aqua regia) or labile (1 M NH4NO3 extract) concentrations in soil but the accumulation factors (leaf concentration: soil concentration) for Cd and Zn followed an inverse log typefunction. Metal partitioning between tissues showed a minimum in the wood, with increasing concentrations of Cd and Zn towards the leaves and fine roots.
