Summary:

The aim of the research project was to test the hypothesis that the white birch as hyperaccumulator of selected trace elements can be used in soil remedia-tion, that it acts as bioindicator in environmental studies and can be a useful spe-cies for planting to restrict migration of trace elements to the forest ecosystem with no adverse impact on its development and proper functioning.
The research presented in this paper relied on a comparison of the mor-phometric parameters of assimilation apparatus in white birch (Betula pendula Roth.) growing in an isolated geomembranes soil, which has received two doses of trace elements in easily digestible forms.
The results showed that the different levels of trace elements have the same impact on the state of assimilation apparatus birch. Given the prevalence of birch in Polish conditions, its good adoption to an environment with a strong human impact and low environmental requirements, this species may be suitable for planting in the form of biogeochemical barriers screening sources emitting trace elements (routes, dumps, landfills, industrial plants, sewage treatment plant).
