| 内容記述 | This study aimed to study the mobility of heavy metals using sequential extraction analysis and assess heavy metals in soil samples of mining tailing around the small-scale gold mining areas at Boroo and Zuunkharaa in Mongolia. The samples were collected from small scale gold mining area existed in Tuv and Selenge province, Mongolia. Physicochemical, chemical and some statistical analyses were made for the mining tailing samples. The pH of the mining tailing samples was determined as 6.10 – 7.37 and the texture was classified in a silt （Si） and silt loam （SiL） types. The contents of As, Pb and Mn in the samples were determined at very high, 1346 – 2970 mg kg-1, 115 – 685 mg kg-1 and 354 – 488 mg kg-1 by using the XRF analysis. From the predictive analysis, the mining tailing samples contain the residues from small-scale gold mining processing that are characterized by relatively high concentrations of heavy metals. Therefore, five steps sequential extraction analysis （Tessier method） was used for the determination of the metals of Al, Mn, Fe, As, Cd and Pb in the small-scale gold mining tailings. In the sequential extraction analysis, Cd, Pb, Fe and Mn are mainly extracted in the Fe/Mn oxides fraction, but As and Al are mainly extracted in the residual fraction. Boroo and Zuunkharaa gold mining area polluted by Pb, Mn, Fe, Al and Cd for measurably level, further assessment of the environmental status is necessary to these areas. | |||||||||||||
