This paper analyzes the presence, distribution and trends in concentrations of heavy metals (lead, cadmium, nickel, zinc, arsenic and chromium) in different environmental media - air, surface water and soil - in the territory of the city of Kragujevac over a three-year period (2022, 2023 and 2024). Special focus is placed on identifying the main sources of pollution, such as industrial activities, traffic and individual combustion plants. Data were collected through regular annual and monthly monitoring reports conducted by city departments and the Serbian Environmental Protection Agency (SEPA). Metal concentrations in suspended particulate matter (PM10) and sediments were analyzed at key measurement sites (Mala Vaga, Medical School). Although most parameters are within the legally permitted limits, continuous monitoring is necessary, especially in urban areas with high traffic volumes. The results for 2024 indicate the need for further integration of local environmental action plans to reduce emissions of carcinogenic metals and protect public health.
