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. 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 was higher. Namely, in exchangeable fraction F1 Cd, Mn and Pb showed an increase in therange 25-40%, in fraction F2 concentrations of As, Cr, Mn and Ni increased in the range of 11-20% and in fraction F3 the significant increase for As (43%), Cr (25%) and Ni (32%) was observed. The APM extraction procedure in presence of surfactant TritonX-100 (0.05 % v/v) was also investigated and the concentration enhancement in mobile and possible mobile fractions of most analytes was observed as well.
