Abstract: In order to separate water-soluble compounds of hazardous elements, a single-step extraction process was carried out and gravitation dust sediment was extracted with distilled and snow water. For the isolation of ion-exchangeable forms, 0.1 mol dm-3 CaCl2 and 0.1 mol dm-3 NaNO3 were used. The determination of the elements content in extracts was carried out with flame atomic absorption spectrometer, the Perkin-Elmer model 3030 equipped with a deuterium lamp for background correction and air/acetylene flame. The total content of selected elements in the sample of the gravitation dust sediment decreases in the order Cu, Zn, Pb, Ni, Cd. From selected elements as water-soluble forms are presented only Cd, Cu, and Zn. Cd, Cu, Pb, and Zn were determined in the solution of CaCl2 and Cd, Cu, and Zn in the solution of NH4NO3 and NaNO3.
