Abstract

V originále

Urban particulate matter (PM) was collected in the most exposed area of Prague, close to highway, from filters of the air conditioning system in one large building. Finally four grain-size fractions: 0.507-0.119 mm, 0.119-0.063 mm, <0.063 mm and sub-fraction <0.025 mm were prepared after drying at the laboratory temperature. Several methods of destructive and non-destructive analysis were used to get elemental size-distributions: the Hg analyser AMA-254 (CV AAS), inductively coupled plasma - mass spectrometry (ICP-MS), electrothermal atomic absorption spectrometry (ET AAS), instrumental neutron activation analysis (INAA), proton-induced X-ray emission (PIXE). Labile forms of toxicologically important analytes (Hg, As, Cd, Cr, Mn, Ni, Pb, Zn) were measured by AMA-254 and ICP-AES in 2M HNO3 extracted solutions.
