Abstract: Determining the origin, content, and dynamics of potentially toxic elements (PTEs) in soil is crucial for assessing pollution levels and their long-term environmental impact, especially in regions like the Municipality of Bor, where mining activities contribute to contamination. This study focuses on the Municipality of Bor, where surface soil samples (0–30 cm) were collected from agricultural land. The dominant soil types include vertisol, dystric cambisol, eutric cambisol, and calcomelanosol. Analysis revealed that concentrations of Ni, Cr, and Co are below the maximum allowable concentrations (MAC). Geochemical limits for Ni (29.20 mg kg⁻¹), Cr (33.63 mg kg⁻¹), and Co (21.50 mg kg⁻¹) were calculated using the Median + 2 MAD method, showing lower values compared to the natural background of eastern Serbia. Humus content positively influences the concentrations of Ni and Co. The correlation of Ni with Cr and Co suggests a potentially common, primarily geochemical origin of these elements. This is further supported by the calculation of the ecological risk index and the pollution index. The established geochemical limits and index calculations provide a foundation for identifying potential risk zones, supporting effective environmental management in the Municipality of Bor.
