Air quality in the city of Bor in 2023

Abstract

The air quality in the city of Bor in 2023 is analysed in this paper. In the period from May 1, 2022 until April 1, 2023 the copper smelter in Bor was not working due to reconstruction and capacity increase. The analyses show that in 2023, no exceeding of the daily limit value for SO2 , PM10, and soot concentrations was detected at any measuring point. During the reconstruction of the copper smelter, correlation coefficients (Pearson) at measurement point "Jugopetrol" between PM10 and the chemical elements Cd and As were moderate (0.6>r>0.4), while in the period before and after the reconstruction of the smelter, they were strong (0.8>r>0.6), and very strong (r>0.8). The results presented in the paper indicate that despite the reconstruction of the copper smelter, the problem of emission of high concentrations of carcinogenic elements in PM10 from the copper smelter is still present. It is necessary to urgently implement additional measures to reduce these emissions to the values provided by law.
