Iodine content in components of ecosystems of Yakutia

Abstract

The problem of iodine deficiency in the ecosystems of Yakutia has a serious impact on human and animal health, affects vital processes and causes damage to agriculture, which requires systematic study. The aim of this study is to investigate the processes of iodine cycling in various components of the ecosystem, including air, soil, water, plants and animals. Research in this direction is becoming increasingly important in view of the widespread problem of iodine deficiency, which affects both the health of the local population and production activities in agriculture. In order to gain an in-deep understanding of the iodine cycle in the ecosystems of Yakutia, the study was conducted in various biogeochemical provinces identified on the basis of landscape and soil criteria. Laboratory methods of biochemical analysis included the kinetic rhodanide-nitrite method, the titrimetric method and the oxidation reaction of the rhodanide ion. The study of the iodine content in the studied components of the ecosystems of Yakutia revealed significant differences in its concentration in various types of water and soils, depending on the biogeochemical characteristics of the provinces. Pasture plants in the Central Yakutia province had a significantly low iodine content than in the Kolyma province, which does not meet the needs of local livestock. This is a potential problem for livestock production and is related to the general trends in iodine concentration in the soils of this province. In general, these results highlight the importance of understanding the biogeochemical characteristics of ecosystems in order to develop effective strategies for managing iodine content in order to ensure human and animal health in Yakutia.
