Chemical elements accumulation specifics in the top of floodplain plants growing in the Yugan river valley of Surgut District, Khanty-Mansi Autonomous District-Yugra

Abstract

The present article describes the heavy metal content (Ni, Pb, Cd) in the top plant phytomass: blue marsh bog (Eleocharis palustris (L.) Roem. Schult.), furcular Anemonidium (Anemonidium dichotomum (L.) Holub), bayonet rush (Juncus filiformis L.), blue marsh vetchling (Lathyrus palustris L.), carex acuta (Carex acuta L.), reed canary grass (Phalaroides arundinacea L.), clump speedwell (Veronica longifolia L.), silverweed cinquefoil (Potentilla anserina L.), common burnet (Prunella vulgaris L.), and water sedge (Carex aquatilis Wahlenb.) growing in the Yugan River valley, Surgut District, Khanty-Mansi Autonomous Distric t- Yugra. Species, morphological and systematic features of plants were accounted. Field and chemical methods were used in the present research. The plant material was analyzed using MGA 915-MD atomic absorption spectrometer. The study revealed that observed plant species differ in heavy metals accumulation specifics, namely: water sedge accumulates Ni, Pb, Cd more than other plant species, sedge sharp - Ni, marsh bog - Ni, reedgrass - Pb, threadfoot - Pb and Cd. Based on the data obtained, we can conclude that Ni, Pb, Cd content was within standard limits in all the studied plants.
