o:358 Concentrations and chemical composition of PM10 and PM2.5 in the town library in Bor, Serbia en Abstract: This paper presents the PM10 and PM2.5 concentrations and results of chemical analyses of PM samples collected at the public library in Bor town, Serbia. 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. Key words: particulate matter, monitoring, air pollution, chemical analyses, arsenic. 1552099 10.5937/SE2101001T 91552100 65060873 2022-05-31T11:42:51.716Z 44 yes 46 Viša Tasić Institut za rudarstvo i metalurgiju Bor ; Mining and metallurgy Institute Bor Bojan Radović Institut za rudarstvo i metalurgiju Bor ; Mining and metallurgy Institute Bor person Aleksandar Simonovski Institut za rudarstvo i metalurgiju Bor ; Mining and metallurgy Institute Bor person Tatjana Apostolovski Trujić Institut za rudarstvo i metalurgiju Bor ; Mining and metallurgy Institute Bor person application/pdf 458439 https://unilib.phaidrabg.rs/o:358 no yes 1 70 92000001 71A03 Safety Engineering: safety of Technical Systems : journal for Scientiest and Engineers Inženjerstvo zaštite: bezbednost tehničkih sistema : naučno stručni časopis 11 1 1 6 Niš Fakultet zaštite na radu u Nišu.
