RESEARCH OF CONCENTRATIONS OF POLLUTANTS IN THE VERTICAL PROFILE OF THE ATMOSPHERE OF THE ZENICA VALLEY USING UNMANNED ARIEAL VEHICLES

This paper presents a study of air pollution in the vertical profile of the atmosphere during periods with and without temperature inversion in the Zenica valley. Unmanned aerial vehicles (drones) equipped with sensors for measuring the concentration of suspended particles, atmospheric pressure and air temperature were used for the study. The measurements were carried out at three different locations in the Zenica valley in two different periods. The study shows that pollutants remain below the inversion layer during the inversion period and that concentrations drop sharply at heights above the floor of the inversion layer. The measurements were carried out in December 2024 and January 2025 at three locations (Institut, Kamberovi apolje and Banlozi) along the Zenica valley, which, in addition to industrial sources of pollution, also contains a large number of small house stows distributed on the slopes of the hills surrounding the Zenica valley on three sides.
