Potentially Toxic Elements Uptake and Distribution in Betula middendorffii T. and Duschekia fruticosa R. Growing on Diamond Mining Area (Yakutia, Russia)

This study was conducted in the territory of the industrial site of the Udachny Mining and Processing Division (Yakutia, Russia). The objects of study were permafrost soils and two species of shrubs (<i>Betula middendorffii T.</i> and <i>Duschekia fruticose R.</i>). Soil and plant samples were analyzed by atomic absorption spectrometry for the presence of potentially toxic elements (Pb, Ni, Mn, Cd, Co, Co, Cr, Zn, Cu, and As). The bioaccumulation factor for each element was also calculated. In the studied plants, the investigated elements were arranged in the following descending row in terms of their content: Mn > Zn > Cr > Ni > Cu > Pb > As > Co > Cd, but in terms of bioaccumulation degree, they decrease in the following row: Cr > Zn > Ni > Mn > Pb > Cu > Cd > Co-for <i>Betula middendorffii</i>, Cr > Zn > Ni > Pb > Cu > Mn > Mn > Cd > Co-for <i>Duschekia fruticose</i>. The bioaccumulation factor results confirmed that <i>Betula middendorffiii</i> and <i>Duschekia fruticosa</i> are resistant to high concentrations of Cr, Ni, Co, Cu, Mn, and Zn elements coherent to kimberlites.
