The Infl uence of Technogenic Landscapes on the Concentration of Chemical Elements in Artemisia Gmelinii in the Trans-Baikal Region

Abstract

The purpose of the research is to fi nd out the infl uence of technogenic landscapes in the ore region on the concentration of chemical elements in plants using the example of Artemisia gmelinii. Materials and methods. The concentration of vital (Zn, Mn, Cu, Cr, Mo, Co) and toxic elements (As, Pb, Cd, Bi Sb) has been determined in Artemisia gmelinii. The research was carried out in the area of the Sherlovogorsky ore district in the south-east of the Trans-Baikal Region. Plant samples were taken during the fl owering period of Artemisia gmelinii, in natural areas and man-made territories. The determination of the contents of chemical elements in plants was performed at the Kosygin Khabarovsk Institute of Tectonics and Geophysics of the Far Eastern Branch of the Russian Academy of Sciences on the ICP-MS Elan 9000 PerkinElmer device (USA) by the method of acid decomposition of HDPE F 16.1:2.3:3.11-98. Results and discussion. It was found that Artemisia gmelinii growing in natural-technogenic and quarry-dump landscapes contained signifi cantly more Zn, Mo, Co, Co, Pb, Cd, As, Sb and Bi in relation to the natural habitats of the plant. The maximum content of Mn was found in natural communities in Artemisia gmelinii. In Artemisia gmelinii, the concentration of Pb, Cd and As in technogenic landscapes exceeded the maximum permissible content in medicinal raw materials. In natural plant communities, the content of these elements did not exceed the established norm. Conclusions. Artemisia gmelinii, growing in technogenic landscapes in the ore districts of the Transbaikal Region, contains higher concentrations of a number of elements, including toxic ones.
