Abstract: The accumulation of harmful microelements in the soil can cause long-term adverse effects, while their deposition can be toxic both for people and the environment. The study of agricultural land flooded in 2014 with tailing outflow due to an accident at the tailing dump of the Stolice mine in Kostajnik (western Serbia) is focused on the contents of heavy metals (Pb, Cd, Zn, Cu, Ni, Cr and Mn) in the soils and the biological activity of these soils. The Stolice-Kostajnik mine belongs to the Zajača mining site in the Boranje area, and its mining operations ceased in 1990. Soil samples were taken from open soil profiles in the flooded and unflooded areas at fixed depths of 0–10 cm, 10–20 cm and 20–40 cm to analyse their physical and chemical properties, the content of heavy metals and the soil’s microbiological properties. The potential environmental risk and the source of heavy metals in the soils studied were determined using the enrichment factor (EF), the potential environmental risk index (RI) and statistical methods such as the principal component analysis (PCA) and the Pearson correlation matrix. Significantly higher concentrations of Pb, Zn and Cd were found in the soil that was flooded with the tailing outflow, than in the unflooded soils. Statistically significant differences were found between the total number of microflora, fungi and Azotobacter in the flooded and unflooded soils. In the flooded soil, the mean values of the enrichment factor (EF) declined in the following order: Zn > Cd > Pb > Cu > Cr > Ni. On the basis of the average value of the potential environmental risk, it was concluded that the flooded soils are classified as at high ecological risk, while the unflooded areas are classified as at low ecological risk.
