The paper presents the results of work on the assessment of the technogenic transformation of heavy metal flows in soils on the Kola Peninsula in 2018. The concentrations of heavy metals in soils are significantly higher than the standards at most sites studied. The average gross Ni content exceeds the standard by 80 times, the content of mobile forms of Ni by 40 times; the average gross Cu content – by 22 times, the content of mobile Cu forms – by 85 times. The maximum concentrations of Ni, Cu, Co are observed at a distance of 8 km from the pollution source in a southerly direction. Mn, Fe, and V are relatively evenly distributed throughout the study area. The concentrations of Ni, Cu, Co, Cd, and Pb in the upper soil horizon are higher than in the illuvial one. This suggests that these metals come mainly from the atmosphere. According to the total pollution index (Zc), the soils of the upper horizon of all sites are classified as dangerous, and at a distance of 8 km from the plant they are extremely dangerous. According to the correlation between the content of chemical elements in the soil, two associations are identified: the first – Ni, Cu, Cd, Pb, Co, Zn and Mn; the second one is Cr, V, Fe, and Sc. In general, despite a decrease in the content of heavy metals in the soil, their amount remains high and a disturbance in the natural geochemical cycle is observed.
