Zinc content in abiotic components (soil-forming rocks, natural water, soil) and in the plants of the forest-steppe, steppe, dry steppe and flood-plain landscapes of Transbaikalia is investigated. A complicated character of zinc distribution in environmental objects is revealed: zinc content in soil-forming rocks and soils of steppe and dry steppe landscapes approximately corresponds to the clarke, while in the rocks and soil of forest-steppe landscapes in is 0.4-0.7 of the clarke level. It is established that the deficit of zinc (20-80 %) in the vegetation of steppe, meadow and agricultural landscapes is characteristic of the majority of the investigated territory.
