Abstract
Heavy metals pollution is considered one of the most significant soil contaminants. Heavy metals present in the soil are not only absorbed by plants but also enter the human food chain through surface and groundwater. They can also enter the human body through atmospheric deposits and dust, posing health risks. Therefore, assessment of the presence and concentration of heavy metals in soil is an important issue. This study aimed to investigate the concentration of certain heavy metals (Cr, Cd, Pb, Ni, Cu, Zn, Mn) in soils affected by major chromium mines in the southern Kerman province, specifically the Esfandeghe, Aseminon, and Dehkahan mines. The results of this study indicated that mining activities can significantly contribute to the presence and occurrence of heavy metals in the surface soil of areas surrounding the mine, placing them in a definite risk range of metals. Among these, the assessment of certain heavy metals such as Zn and Cu, which may originate from agricultural activities and management practices like fertilization and pesticide use, was prevalent and in a definite risk range in the studied agricultural land (an orchard near the Dehkahan mine). This result indicates that agricultural activities may also have contributed to the increase concentration of heavy metals in the soils. however, the pollution with a definite risk level in soil around the mines, especially concerning Cd, Ni, Pb and Cr, suggests that mining activities, if not managed and controlled, can be a main source of soil and environmental pollution and the associated risks.
