The contribution deals with the atmospheric deposition of solid particles and selected elements in the typical urban area with many sources of pollution. The main sources of pollution are represented by neighboring the iron and steel works and the thermal power station. The samples were collected from the eleven sites, which are located from 3.6 to 16 km from the iron and steel works. Qualitative and quantitative characteristics of the total deposition of solid particles, the deposition fluxes of elements Fe, Al, Mn, Zn, Pb, Cu, Cr, Cd, As and their seasonal variations were studied. Results from the years of 2009–2018 are introduced. The research has shown a significant influence of local sources of pollution on the studied parameters of atmospheric deposition. Compared to the values of deposition measured in the other areas, extremely high values of iron (28, 120), manganese (1,106) and chromium (34.1 μg.m–2.day–1) deposition as well as high, above-average values of other monitored elements were measured in the proximity of the ironworks. The portion of emission sources of iron and steel works on the Fe fluxes at the individual sites in the city was calculated in the range from 24.7 to 54.1%. On the basis of the emission situation of the monitored area, it is possible to use selected compounds of the AD as an environment quality indicator and to quantify the contribution of emissions to area’s environmental stress.
