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

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