Biogeochemical researches of trace elements content in vegetation of Tatarstan

The paper presents the review of the results of studies of trace elements contents in wild plants in the Middle Volga conditions (in the example of the Republic of Tatarstan) based on literature data and data obtained by the authors. The natural range of natural concentrations has been determined. A comparison of the concentrations of microelements obtained by different authors made it possible to establish that the microelements contents in herbaceous plants of the Republic of Tatarstan does not exceed the world average clarke. The content of Cu and Zn tends to the lower limit. The identified tendency for the trace elments accumulation in plants allows to conclude about a relatively favorable biogeochemical situation in the republic as a whole. Individual local biogeochemical specializations of plants are determined by the natural geochemical background of the region

Biogeochemical specialization of A

Properties of trace elements accumulation (Mn, Fe, Zn, Cu, Cr, Pb, Ni, Co, Cd) in plants of Aegopodium podagraria L. in conditions of the Middle Volga region of Russia within the Republic of Tatarstan are considered. The biogeochemical specialization of Aegopodium podagraria L. depending on phytocenotic conditions has been established. Organospecificity of trace elements accumulation in Aegopodium podagraria L. is revealed
