It is the first time that in the detritus of biological origin that formed over a 7-month period in water microcosms with aquatic mollusks (Viviparus viviparus, Unio pictorum), and aquatic plants (Ceratophyllum demersum), a number of chemical elements were measured. This is the first study to determine concentrations of these chemical elements in biological detritus, including uranium, gold, and rare earth elements. Neutron activation analysis showed that the elements' concentrations decrease in the following order: Ca > Zn > Ba > Br > Ce > Se > Nd > La > U > Hf > Sb > Th > Sm > S > Cs > Au. The data obtained contribute to understanding of the polyfunctional role of aquatic organisms in aquatic ecosystems, and the important role of biological detritus produced by the organisms, especially in biogeochemistry of water systems.

NOVELTY, WHAT IS NEW:
this is a first publications and the first research data on chemical content of sediment that was formed under controlled conditions. This is a model of organic matter in sediments in aquatic bodies and streams.
