- Abstract
A study of characteristics and speciation of 7 heavy metals in agricultural soil near mining smelting of Hezhang were analyzed. The heavy metal concentration were determined by using ICP-OES, the chemical fraction concentrations of heavy metal extraction were used a modified BCR-SEPs. Tucker 3 was used to analyze the relationships between speciation data. Our results showed that the concentration of As, Cd, Co, Cu, Ni, Zn and Cr in all studied areas were higher than background of Guizhou, whereas As, Cu, Zn and Cd were higher in mining area; Ni and Cr in mountainous area and Co in smelting areas. Zinc was the most serious pollution element in all studied areas. The chemical speciation of heavy metals were relatively higher in residual fraction (F4) especially Cu and Cr in the studied areas. The Co element was the highest percentage in acid secondary-phase (F1+F2+F3). However some elements such as Zn in mining area and As, Co in both smelting and mountainous areas were relatively high in reducible fraction (F1). Tucker 3 results showed As, Cd, Cu, Zn, mainly from mining and smelting activities, mining areas (M1, M2, M15) was particularly evident, mainly in residual fraction. Cu was mainly due to the impact of mining and smelting (Model B1), while a small part of Cu exhibited similar source to Co, Cr, Ni (Model B2).
