The contamination of urban soils with heavy metals poses a threat to both the ecosystem and human health. Despite its relatively small population, Pavlodar serves as the industrial center of Kazakhstan, yet its soil pollution is comparable to that of major industrial cities worldwide. This study examines the problem of soil contamination in the city of Pavlodar with heavy metals and its potential impact on the environment and human health. The study used a variety of indices, including pollution indices, ecological risk assessments and potential health risk assessments. This study considered the territorial patterns of the distribution of microelements in the soil. The results revealed that the highest concentrations of most metals were found in the central part of the city, whereas the northern industrial zone was the least polluted. The pollution indices generally indicate low levels of soil pollution, but increased level was observed in the city center. A high carcinogenic risk for children associated with the chromium content in soils has been observed. In general, this article emphasizes the need to control and monitor the level of soil pollution in the city of Pavlodar to protect the environment and ensure public health.
