High level of arsenic in suspended particulate matter (PM) is of a predominantly industrial origin. The major source of pollution is the copper smelter, which is situated in the close vicinity of the urban area of Bor. The ambient level of As in PM is influenced by meteorological parameters as well as the remoteness from the copper smelter. Continual exceedances of the annual limit value (LV) for As (6 ng m-3) were recorded at the measuring sites in the urbanindustrial and suburban areas. Maximum annual As concentration recorded at the site Jugopetrol (550 ng m-3) in 2019, was more than 90 times higher compared to the LV. The daily concentration of arsenic in April 2022 also exceeded the limit value by more than 100 times in relation to the LV.enarsenicparticulate matterair qualitymining-metallurgical processesconferenceObject
