Assessment of non-carcinogenic risk for the child population health from chemical substances taken with the motor vehicle exhaust gases in 4 districts of the city of Kazan based on the monitoring data from FSFHI “The Center of Hygiene and Epidemiology in the Republic of Tatarstan” for the period from 2015 to 2021 was carried out. The average annual concentrations of chemical substances exceeded the allowable level of standards (MAC) from 2.32 to 9.96 of MAC in all zones. The value of the total daily dose on the inhalation route of the substances’ intake with atmospheric air (I) made 1.09 – 10.33 mg/(kg x day) depending on the zone. An unacceptable level of non-carcinogenic risk (HI>3.0) was determined in all zones. In zones 2 and 4, the major impact on the RS was made by soot (HI 13.1), in zone 1 – by complex intake of all fractions of suspended particulate matters, with maximal level of PM 2,5 (HI =5.98), in zone 3 – by intake of РМ 10 (HI 7.83). Black carbon (ВC) was found to be an important indicator, as well as PM 2,5 and PM 10, for assessing the road traffic impact on the air quality and health. The children living in zones 2 and 4 are most vulnerable to non-carcinogenic risk as far as the respiratory system, which is formed due to complex intake of ВC, РМ 10 and РМ 2,5. Transition to a complex assessment of risk from chemical substances with the account of contribution of certain substances is an important decision in determining the priority actions for minimizing the children’s health risk at regional level.
