Two sampling campaigns were carried out during six consecutive working days in June 2015 and in March 2016. The results show that PM10 and PM2.5 concentrations in the library were strongly connected with the respective PM concentrations in ambient air. So, most PM particles in the library originate from the outdoor air. High PM2.5/PM10 ratios in both indoor and outdoor environments indicate the considerable influence of anthropogenic air pollution sources, in this case, metallurgical processes in copper smelting plants. Because the new copper smelting plant started operating in 2016, it is necessary to conduct a new measurement campaign to determine whether there are changes in the concentration levels and chemical composition of PM in the indoor air of public and residential buildings in Bor. eng info:eu-repo/semantics/article Fakultet zaštite na radu u Nišu.
