Abstract: The BCR recommended sequential extraction procedure and single extraction with EDTA were modified for this study. Single and sequential extraction procedures were applied to four sediment samples coming from industrially polluted region of Eastern Slovakia. This paper describes the preparation of samples, gives analytical results in each extraction step for cadmium, lead, copper. and chromium and brings comparison of these results with total element content analyses realized by independent spectral method. Spectrochemical methods are in general predominantly used for assessment of element contaminants in various components of the environment, though in actual geochemical research the optical method took a representative place as an analytical ending with respect to the element detection.
