Abstract
Monitoring with soil samples was conducted in area with intensively exploitation of copper minerals (copper mine “Bučim” near Radoviš, Republic of Macedonia. Soil samples from the surface layer (top soil) and from the deep layer (bottom soil) at the same locations were collected. Characterization of 18 elements contents was done: Al, As, Ba, Ca, Cr, Cu, Ga, Li, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, V and Zn. Close mine environment was concern with higher Cu contents (max. value obtained 1200 mg kg-1), but the rest of the area was characterize with median value for copper content of 23 mg kg-1. The enrichment factor of TS/BS for Cu was 2.8 for whole study area and ~10 times for very close mine environment. For the rest of the potentially anthropogenic elements (Cr, Ni, Pb, V, Zn) no significant enrichment factors were found for TS/BS relation. The lithogenic elements (Al, As, Ga, Fe, Li, Mg, Mn, Na, Sr) content showed stability in the vertical direction (TS/BS); but in a across direction, variability of element contents undergoes with the geology of the region. Characterization of elements contents is in order of the type of land use. Maximum values for Cr, Ni and Pb were found in cultivable area (290 mg kg-1, 190 mg kg-1 and 130 mg kg-1, respectively). Coefficients of correlation for the contents of the elements are represented in the matrix of correlation coefficients. With the factor analysis the distribution was reduced to three synthetic variables, which showed linkage in terms of geochemical similarities: F1 (Al-Ca-Cr-Fe-Mg-Mo), F2 (Li-Mn-Na-Ni-Pb) and F3 (Ba-Sr), including 75% of the variability of analyzed elements. Spatial distribution of As, Cu, Pb, V and Zn showed that higher contents of these elements are deposited in mine vicinity; due to dust distribution from ore and flotation tailings. Distant areas were not concerned.
