Abstract

This article presents the results of a study on the composition of organic matter in the bottom sediments of the coastal zones of the Verkhnetobolskoye and Karatomar reservoirs located in Northern Kazakhstan.Fieldwork was conducted during the winter season using adapted methods for sampling beneath the ice cover, which made it possible to obtain reliable data under low-temperature conditions.

During the study, quantitative indicators of organic matter content in sediment samples were determined, and their qualitative composition and potential impact on the aquatic environment were assessed.

The obtained data may serve as reference material for evaluating the ecological condition of bottom systems in freshwater reservoirs located in temperate climate zones.Furthermore, the results are of significant practical value for the development of methodological recommendations on organizing and conducting comprehensive monitoring, including express analysis and toxicity assessment of solid-phase fractions using X-ray fluorescence spectroscopy.Given the widespread agricultural use of the water resources of these reservoirs, the research findings can also be applied in planning agroecological measures and ensuring sustainable land use in the region.Additionally, bottom sediments may be considered a potential resource for use in agriculture as organomineral fertilizers or for the reclamation of degraded lands.
