Abstract: This paper presents the results of the air quality measurements in the agglomeration of Bor in the period June-December 2022, in which the Copper Smelter in Bor was not working due to the works on reconstruction and increasing the capacity for copper concentrate processing. Based on an analysis of the existing measuring points and concentrations of pollutants, measured in the local and national air quality monitoring network in the territory of the Bor agglomeration, as well as the possible impact of the new mining and metallurgical facilities in the company Serbia ZiJin Copper Bor, the additional locations, where the measurements were performed, were selected. The air quality measurement results show that there was no exceedance of the hourly and daily limit values for gaseous pollutants, nor were there an exceedance of the limit value for the mean daily concentration of lead in the suspended particles of the PM10 fraction, as well as the target values for the concentrations of cadmium and nickel in PM10. The arsenic concentration in PM10 at the measuring point of PU Bor was above the target annual value for 3 days. The maximum measured mean daily value of arsenic concentration in PM10 at this measuring point was 11.3 ng/m3. Based on a complete insight into the results of air quality measurements in the Bor agglomeration in 2022, it can be concluded that the dominant share of concentration of SO2, CO, as well as the concentration of arsenic, cadmium, and lead in PM10, originates from the gaseous pollutant emissions from the Copper Smelter Bor in the period when it operates. It was established that at the measuring point MMI Bor, the nitrogen oxide emissions from traffic mostly affect the level of nitrogen oxides in the air. Also, the measurement results indicate that the operation of the Smelter in 2022 did not significantly contribute to the concentration increase of suspended PM10 particles in the agglomeration of Bor, and that during the period of operation of the Copper Smelter in 2022, no copper concentrates with increased nickel content were processed.

Izvod: U ovom radu prikazani su rezultati merenja kvaliteta vazduha u aglomeraciji Bor u periodu jun-decembar 2022. godine u vreme kada topionica bakra u Boru nije radila zbog radova na rekonstrukciji i povećanju kapaciteta za preradu koncentrata bakra. Na osnovu analize postojećih mernih mesta i koncentracija zagađujućih materija koje se mere u lokalnoj i državnoj mreži monitoringa kvaliteta vazduha na teritoriji aglomeracije Bor, kao i mogućeg uticaja novih rudarskih i metalurških objekata u kompaniji Serbia ZiJin Copper Bor, izabrane su lokacije na kojima su vršena merenja nivoa zagađujućih materija, a koje nisu u sastavu državne ili lokalne mreže monitoringa kvaliteta vazduha. Rezultati dodatnih merenja kvaliteta vazduha pokazuju da nije bilo prekoračenja satnih i dnevnih graničnih vrednosti za gasovite polutante, kao ni prekoračenja granične vrednosti za srednje dnevnu koncentraciju olova u suspendovanim česticama frakcije PM10 kao i ciljanih srednjih godišnjih vrednosti za koncentracije kadmijuma i nikla u PM10. Koncentracija arsena u PM10 na mernom mestu PU Bor bila je iznad ciljne srednje godišnje vrednosti u trajanju od 3 dana. Maksimalna izmerena srednja dnevna vrednost koncentracije arsena u PM10 na ovom mernom mestu iznosila je 11.3 ng/m3. Na osnovu kompletnog uvida u rezultate merenja kvaliteta vazduha u aglomeraciji Bor u toku 2022. godine može se zaključiti da, u periodu kada topionica bakra radi, dominantan udeo u nivoima SO2, CO, kao i koncentracijama arsena, kadmijuma i olova u PM10 potiče od emisija gasovitih polutanata iz topionice bakra. Utvrđeno je da na mernom mestu IRM Bor, na nivo azotnih oksida u vazduhu dominantan uticaj imaju emisije azotnih oksida poreklom iz saobraćaja. Takođe, rezultati merenja ukazuju na to da rad topionice u 2022. godini nije u većoj meri doprineo povećanju koncentracija suspendovanih čestica PM10, i da u periodu rada topionice bakra u 2022. godini, nisu prerađivani koncentrati bakra sa povećanim sadržajem nikla.
