Heavy Metals of Benthal Deposits of Some Lakes of Khanty-Mansi Autonomous District-Yugra, Surgutsky Region

Authors : Gulnara Shigabaeva

Abstract: Experimental data were obtained on the gross content as well as on the content of movable forms of heavy metals, cuprum, manganese, cobalt, nickel, zinc, chromium in benthal deposits of some lakes of Khanty-Mansi Autonomous District-Yugra, Surgutsky Region. Elements under study in the order of mineral dressing of benthal deposits can be arranged in the descending sequence: Cr>Cu>Zn>Co>Ni>Mn. Calculated clarkes of concentration (Kk ) for microelements were: for Mn-0.041; Ni-0.39; Co-0.43; Zn-0.44; Cu-0.53; Cr-0.73. The local geochemical background of benthal deposits is not exceeded for all studied elements. It was elicited that up to 68% of Co, 51% of Mn up to 30% of Zn, 8.4% of Cr, 5.5% of Ni and 3.2 % of Cu are in the movable form ejected with acetate-ammonium buffer solution (pH = 4.8). Contents of heavy metals were determined with the use of flame Atomic Absorption Spectrophotometry (AAS) method on AA 6300 spectrophotometer of "Shimadzu" company.
