Gross Content and Mobile Forms of Halogens (Fluorine, Bromine and Iodine) in the Soils of Republic of Tyva

Abstract

The chemical composition of the soils of the Republic of Tyva has been studied and evaluated from an ecological standpoint. This is important both from a scientific and practical point of view. Halogens play a significant role in the vital activity of living organisms. They, like other macro- and microelements, are involved in the process of forming the food chain: atmosphere - soil - natural waters - plants - animals - man. When assessing the biogeochemical value of a particular halogen, it is important to know not only its gross content, but also the concentration of its mobile forms capable of migration and participation in the dynamic equilibrium between the solid phase of the soil and the soil solution. This is due to the fact that plants are supplied with nutrients due to the mobile forms of various elements. At the present stage, the study of halogens is clearly insufficient, fluorine is among the most studied, iodine is less, and bromine is very poorly studied.
