| 内容記述 | This study aimed to study about physicochemical properties and heavy metal contents of mining tailing samples around the small-scale gold mining area in Mongolia. The mining tailing samples were collected from 10 points of three different area of central and northern part of Mongolia. The pH of the mining tailing samples were determined as 6.10 - 7.37 and texture of the mining tailing samples were classified as silt and silt loam. The electrical conductivity is higher in the sample MTl and MTI0. The ignition losses and organic matter of the mining tailing samples were ranged 1.77-7.01 % and 0.55-1.31 %, respectively. The content of SO4^2- was lower than HCO3- + CO3^2- and CL^- in the mining tailing samples. Total N and total C contents varied from 0.016 - 0.075g kg^-1 and 1.465 -4.130 g kg^-1, respectively. The contents of As,Pb, Cu and Mn were determined by XRF analysis, 1346 - 2970 mg kg^-1, 115 -685 mg kg^-1, 20 -70 mg k g^-1 and 354 -488 mg kg^-1, respectively. These results indicates that the mining tailing samples containing high amount of heavy metals which would affect to human health where living near around small-scale gold mining area. | |||||||||||||
