| Description | 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. |
