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.
