The model forms used in the experiments were Cu complexes with benzyl- and hexadecylmalonic acids, simulating low-molecular dissolved organic substances. The complexes of Cu with hexadecylmalonic acid are found to be absorbed by suspensions and removed into bottom sediment more actively than other Cu forms.

Kuznetsov I. Yakushev E. Summary: The work is devoted to the study of hydro capacity and biogeochemical regimes of meromictic reservoir using integrated biogeochemical model OxyDep and three-dimensional hydrodynamic model GETM on the example of Hunnbunn model and Shatursky lakes coolers. Parameterization of oxygen depletion processes was the main purpose, which lead to the formation of anaerobic conditions in the water column.
Comparison of Cu and Zn cycling in eutrophic lakes with oxic and anoxic hypolimnion
The OxyDep model takes into account 5 main variables: dissolved oxygen, inorganic nutrients, dissolved organic matter, suspended organic matter, biota and describes the main processes responsible for changes in conditions of oxygen in the water column, that is synthesis of organic matter, decomposition of organic matter in the process of oxygen oxidation or denitrification, oxygen consumption for oxidation of metals Fe, Mn , and sulfur and boundary processes exchange at the "air-water" and the exchange between water and sediment.
The results of the experiments reproduced the observed features of the structure of the reservoir and allowed to find the main factors determining the formation of biogeochemical structure of meromictic water bodies. Analysis of the results of the experiments and comparisons with observations have shown that the simplified biogeochemical model can be used as an effective tool to study and predict changes in oxygen and nutrient regimes.
