Contents of ABD, as well as Pb, Cd, As, and Ni in ABD were evaluated for a 10-year period (2013⎼2022), at four measuring sites in the urban-industrial, urban and industrial zones in the area of the City of Bor, which were under the influence of the polluting substances from the copper mining and smelting operations. The number of the measuring sites at which contents of ABD were above the Maximum Allowable Concentration (MAC) decreased over time, which was in accordance with the general decline of ABD contents, especially at the measuring sites Bolnica and Šumska sekcija. The measuring site Institut was the exception, due to the increasement of contents of the analysed polluting substances in the recent years. This could be the consequence of the wet and dry deposition of the dispersed particulates of the flotation copper concentrate, in the course of handling it and the vicinity of the road and railway transportation routes to the measuring site Institut. The implementation of the flesh smelting technology and continuous reconstructions of the copper smelter facilities have led to the general improvement of the annual air quality in the City of Bor concerning the contents of ABD and the analysed elements in ABD, but it seems that new nonstationary sources of the environmental pollution could change pollution trends in future years.enatmospheric bulk depositionPbCdAsNiconferenceObject
