The total non-carcinogenic risk was higher in the Kirovsky and Vakhitovsky districts of the city, and the dermal path was the most significant among the chemical penetration pathways. The distribution of risk factors for adolescent health along the path of inhalation was determined for the various critical target organs such as kidneys, hormones, blood, and respiratory systems. Analysis of the content of total metals in the soils of different districts showed that copper, zinc, lead made the major contribution to pollution in the calculation according to MAC (Zc) in all districts. Nitrates remain an important contaminant in every city under study. The values of total pollution factor, both for total and mobile forms of metals, did not exceed 16 units allowing placing the samples under study into a category with allowable contamination. The content of mobile forms of metals (apart from cadmium) did not exceed regulations in all selected zones. However, according to the results of our research, the concentrations of mobile forms of metals exceeded the concentrations of total forms of the same metals by approximately two times (but stayed within the limits of MAC).
