چکیده انگلیسی
A one-year study on total air-borne particulate matter has been undertaken in the framework of air pollution project in Bratislava. The 16 filter samples were collected in 2004 in order to evaluate the level of pollution and assess the potential environmental hazards in Bratislava. As a result of two irradiations with neutrons and four gamma-spectrometric measurements the concentrations of 30 chemical elements (Na, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Ga, As, Se, Br, Rb, In, Sb, I, Cs, Ba, La, Sm, Dy, Tm, W, Au, Hg, Th, U) were determined using instrumental neutron activation analysis (INAA). Additionally the concentrations of other six elements (Cr, Ni, Cu, Zn, Cd, Pb) were measured by atomic absorption spectrometry (AAS). The comparison with other European cities was carried out. Crustal enrichment factors were calculated in order to distinguish the possible sources of air-borne particulate matter. For some elements elevated concentrations were observed for the summer months. The other concentrations were relatively stable over the year.
