This work is focused on the experimental determination of the effect of extraction time and pH of the 0.05 M EDTA on the extraction degree of selected elements. It has been determined that the pH of 0.05 M EDTA = 7 ”as specified by the norm” is possible to be used for the extraction of the dust sediment but the 1-hour extraction is not satisfactory for the isolation of all mobilizable elements forms.
