Abstract

Aluminum, Sc, Th, Hf, and lanthanoids belong to groups of elements that are, slightly, very slightly, and moderately captured in marsh ecosystems. In the genesis of the peatbog the biogeochemical migration of elements is mainly determined by the quality of the humus barriers as well as by the capability to form intermetallic compounds of widely varying compositions. In the surface layer (10 cm) of the peatbog the highest content of Al, Hf, Ce, and Sm over the entire history of marsh development was observed. This fact reflects the modern tendency to forming technogenic streams of the above content.
