Mobility of important toxic analytes in urban dust and simulated air filters determined by sequential extraction and GFAAS/ICP-AES methods

Original language description

The modified BCR three step sequential extraction procedure has been applied to homogenized urban dust samples (APM) and to simulated air filters (acetyl cellulose, diameter of 47 mm and pore size 0.45 &#956;m) loaded with APM by the wet deposition process. The homogeneity of bulk APM and loaded filters, and total concentrations were carried out using several analytical methods (INAA, PIXE, GFAAS, ICP-AES, ICP-MS). Investigated trace elements in chemical fractions, selected according to their adverse effects on human health: As, Cd, Cr, Mn, Ni, Pb, were analyzed by ICP-AES and GFAAS, respectively, depends on concentration levels. For validation of extraction procedures the SRM 1648 Urban Particulate Matter (NIST) was taken and very good agreement was obtained with comparative data from a capillary electrophoresis (CE) method. Differences between extracted portions of analytes in APM and in simulated air filters were found, the mobility of some analytes in case of simulated air filters
