FEATURES OF TRACE ELEMENTS ACCUMULATION IN VACCINIUM VITIS-IDAEA LEAVES IN THE LIGHT-CONIFEROUS FORESTS OF IKATSKIY RANGE (BAIKAL REGION)
The aim of our study was to determine the trace elements content (Mn, Fe, Zn, Cu, Cr, Pb, Ni, Co, and Cd) in Vaccinium vitis-idaea leaves grown in the light-coniferous forests of Ikatskiy range. Element content was measured by atomic absorption spectrometry (AAS,AAnalyst 400 PerkinElmer). Results obtained indicated that the metals concentrations in the leaves ranged from 0,05 (Cd) to 576 (Mn) ppm. The row of the elements accumulation in the leaves is: Mn > Fe > Zn > Cu > Cr > Pb >Ni ≥ Co >Cd.According to the coefficients of accumulation leaves acted as accumulators of Mn, Cu, Zn (CA > 1) and excluders of Fe, Cr, Ni, Pb, Co, Cd (CA < 1). Significant correlations were found between content acid-soluble forms Cr, Mn, Fe, Cu in the soil and leaves (r = 0,48–0,76). The toxic trace element (Pb, Cd) analysis demonstrated that their content was safe for human consumption.
