| Abstract | The total and extractable forms of Cu, Zn, Pb, Ni, Cr, and Fe in vineyard soils from the valley of Valandovo were analyzed in order to understand the existence of metals in soils and their potential availability to the flora and fauna. The content of metals was determined by ICP-EAS analysis, while metal binding was defined with a sequential extraction procedure. The total content of Cu, Zn, Pb, Ni, Fe and Cr, in almost all soil samples, did not exceed the maximum permissible content (M:PC) of trace elements in soils proposed by the New Dutchlist. The only exception was the soil sample R(3), where a higher content was measured especially for Fe, Ni and Cr and to a lesser extent Cu and Zn. Sequential extraction showed that the distribution of metals increased in the order: oxidizable > residual fraction > reducible fraction > exchangeable, water and acid soluble in soil. From this study, it can be concluded that the increased content of heavy metals in the area around the village of Rabrovo can be explained by past mining activities and the partial transfer of heavy metals in the soil. However, the low value in the mobile exchangeable fraction and the physico-chemical characteristics of the studied area indicate a low potential risk to the surrounding environment. |
