o:360 Chemical composition of particulate matter in the indoor air at the technical faculty in Bor (Serbia) en Abstract: This paper presents part of the research results of human's exposure to air pollution with suspended particles in selected educational and residential buildings in the town of Bor. In recent years, special attention has been paid to indoor air quality, because people spend a large part of their time during the day in closed micro-environments. Mass concentrations of 24 chemical elements were determined from PM10 samples collected in the selected classroom at the Technical Faculty in Bor during March 2018. Major elements (Fe, Al, Na, Mg, Ca, K) and trace elements (As, Cd, Pb, Ni, Zn, Cu, Ti, Co, V, among others) were analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) and Inductively Coupled Plasma Mass Spectrometry (ICP MS), respectively. The phase composition of the total suspended particulate matter (TSPM) samples was determined by X-ray powder diffraction (XRPD) analysis. XRPD analysis of the SPM samples identified: calcite (CaCO3), quartz (SiO2), gypsum (CaSO4x2H2O), dolomite (CaMg(CO3)2) and plagioclase (albite – NaAlSi3O8).
