Comparative Analysis of the Elemental Chemical Composition of Padus avium Shoots from Antropogenically Disturbed Ecotops

Abstract

In order to use vegetative resources more efficiently nowadays a possibility to produce food supplements enriched with biologically active substances and also combined types of medical plant raw materials from wood pulp of crown is considered. When using plants growing on anthropogenically transformed territories, the issues of accumulation of chemical elements (CE) potentially hazardous for human in them become decisive. There have been studied mechanisms of CE distribution in Padus avium fruits, leaves and stems from anthropogenically transformed ecotopes in the south of Western Siberia. The content of CE has been studied by the atomic emission spectrometry after dry ashing. Element chemical composition of soils of studied habitats is characterized by high variability and absence of significant differences. The amounts of CE in fruits, leaves and lignified stems of Padus avium from anthropogenically transformed ecotopes with the different degree of environmental footprint do not differ significantly. Relatively stable content of CE is mainly peculiar to the essential elements of Ca, K, Mg, P, B, Cu, Zn and Pb, Sn, V as well. High variability is recorded for CE strongly associated with finely dispersed soil particles (Al, Cr, Fe, Mn, Na, Sc, Si, Ti). Higher concentration of Sr specific to other plants in the south of Western Siberia is observed in all studied samples. A sustainable difference was recorded in CE's concentration in the studied organs. The minimum percentage of the most part of the elements was found in fruits (apart from B) and stems (apart from Zn). Leaves contain several times more CE which may be due to a higher contribution of soil particles. The exceedence absence of maximum permissible concentrations of potentially hazardous CE and presence of biologically active compounds in fruits and leaves indicate the capability of usage crown wood pulp of P. avium in food and beauty industries as a source of biologically active substances and natural dyes.
