Abstract
The microelement composition of the water-bottom sediments-macrophytes-macrophytes-macrofauna system was considered р. Cupid. Installed minimal and the maximum concentrations of trace elements in of its individual components. It is shown that the content of microelements in biological objects decreases in the following order: algae > macrophytes > ichthyofauna. The most informative biological object of microelement accumulation in the Amur ecosystem are algae. Accumulation of Fe, Mn, Zn and Cu in bottom sediments is associated with the formation surface complexes of metal cations with clay minerals and with their accumulation of diatoms.
