GEOCHEMICAL FEATURES OF THE FILIPENDULA ULMARIA (L.) MAXIM (ROSACEAE) ELEMENTAL COMPOSITION IN THE TERRITORY OF NOVO-URSKOE TAILING, KEMEROVO REGION
Abstract
The relevance of the research is caused by the need for comprehensive information on the impact of biogeochemical background radical changes in the areas of mining enterprises tailings distribution. The research is aimed to predict routes of toxic components migration. The aim of the research is to identify the changes in elemental composition of the root and overground sections of Meadowsweet (Filipendula ulmaria (L.) Maxim.) and to determine indicators of the Novo-Urskoe deposit tailing`s technogenic impact. The objective of the research is to determine coefficients of chemical elements concentrations relative to the background values as well as coefficients of the chemical elements accumulation in the root section of the meadowsweet in reference to overground one. Another objective of the research is to study the features of the spatial distribution of chemical elements in overground and root sections of meadowsweet in the tailing site. Methods. Sampling was arranged on the flanks of Novo-Urskoe tailing. The elemental composition of meadowsweet was carried out by the certified methods using the technique of mass spectrometry with inductively coupled plasma (ICP-MS) in the laboratory of the «Plasma» analytical center (Tomsk city). The analytical data processing was performed through Statistica 6.0 and Excel programs. Maps of elements distribution in overground and root sections were made using the programs: Surfer (11), CorelDRAW (16). Results. Accumulation of 67 chemical elements in meadowsweet from Novo-Urskoe tailing in Kemerovo region was studied. Coefficients of element concentrations relative to the background and a clark of the noosphere were calculated. The authors have compiled the geochemical ranks, showing accumulation of elements such as Zn, Ba, Pb, Tl, Se, Ag, W, Hg, Au, P, which exceed background values in 5 and more times. Maps of spatial distribution of chemical elements in meadowsweet showed that the highest concentrations of elements are in the area of the dump of oxidized ore processing and in the area of dispersion flux. The coefficients of accumulation of chemical elements in the root section of meadowsweet in reference to overground section were calculated. The authors identified the increased concentrations of chemical elements in the roots approximately in 80 % of cases.
