520 3 |a Two existing sequential chemical extraction schemes, involving respectively five and six leaching steps with solutions of increasing dissolving power, were compared. The methods have been applied to surface sediment samples collected in a marine estuary zone potentially exposed to contamination arising from nearby industrial activities. A certified reference material (MURST-ISS-A1) consisting of an Antarctic bottom sediment for which no information regarding phase dependent concentration is available, was also analyzed. In order to evaluate the partition of metals among different geochemical forms, the concentrations of cadmium, chromium, lead and zinc were measured in the liquid extracts by Zeeman-corrected flame atomic absorption and by inductively coupled plasma-atomic emission spectrometry. The total metal concentrations were determined after strong acid attack, and the adequacy of this total digestion/dissolution technique was verified by its application to the reference material. Comparison of total metal concentrations with the sum of concentrations associated with the individual phases was employed to assess possible analyte losses or contaminations. Precisions for both sequential procedures were comparable, but some inconsistencies in mass balances were found in one of the samples for the distribution of Zn in the soluble/exchangeable fractions and for Cd in the bound to carbonates form. In addition, the six steps procedure produced lower concentration values in the case of elements associated to the residual fraction. For the five steps method mass balances showed acceptable agreement, with average recoveries in the 87 to 106% range. On the whole, differences in metal distributions were observed, being more marked for the bottom sediment. Significant proportions of the studied elements, with the exception of Cr, were found as easily extractable forms. X-ray diffraction and petrographic observation of the surface sediments allowed qualitative correlation between the leaching results obtained and the presence of defined geochemical phases. © Springer-Verlag 2001.  |l eng
