Abstract:

This article presents the results of a hygienic health risk assessment caused by chronic inhalation exposure to priority ambient air pollutants. The study was conducted in Surkhandarya region of the Republic of Uzbekistan, characterized by a combination of industrial, transport, and agricultural pollution sources. Based on data from Uzhydromet for 2022-2023 across four key areas (Termez city, Denau city, Shurchi and Boysun districts), hazard quotients (HQ) for non-carcinogenic effects and hazard indices (HI) were calculated, and the territories were ranked by risk level. The most unfavorable situation was identified in Termez city (HI = 2.7), where an unacceptable level of non-carcinogenic risk is formed, primarily due to fine particulate matter (PM2.5) and nitrogen dioxide. In other districts, the risk was assessed as acceptable (HI < 1.5). Recommendations for priority control and monitoring measures are provided.
