Abstract

In order to determine the level of contamination of the area, the formulas of Muller, Hokonson and Nemerow were used. Using the information of 2009 on this area, the changes by years were analyzed with the results obtained during the scientific research. The advantage of using pollution indicators is the possibility of direct comparison of different objects in the world; used conditional on geochemical background values. Thus, indicators provide direct information about the quality of the soil environment, and pollution indices are a tool for objective assessment. When comparing the results of 2009 and 2021 along the same route with a 12-year difference, the indices have changed, pollution at a distance of 2 and 8 km has changed to an average index. These indicators mean that during the years of the operation of the combine, the index of soil pollution will increase, and it will increase by one class every 10 years.
