Abstract

A three-stage sequential leaching procedure was applied to the determination of the distribution of trace elements in filter-collected aerosols. Sampling was performed at a moderately polluted city (Veszprém) and a regional background sampling site (Kabhegy). A validated sequential leaching technique was applied and 12 elements (Al, Fe, Ca, Mg, Mn, Pb, Cd, Cr, Cu, Ni, As and V) were measured. Distribution of the elements was determined for environmentally mobile, carbonate and oxide associated, and environmentally immobile (bound to silicate) fractions. Lead was found in the highest amount in the environmentally mobile fractions and cadmium was mainly associated with environmentally immobile fractions. The data obtained provide information on the source of the elements and on their potential mobility following the deposition of the aerosols on the land and water surface.
