Evaluation of extraction/digestion techniques used for the determination of the lead isotopic composition in forest soils

Original language description

Lead isotopic studies in soils present an efficient tool for tracing the sources of lead pollution. Five different extraction/digestion techniques (0.05 M EDTA, 0.5 M HNO3, 2 M HNO3, aqua regia, total digestion) were used for lead isotopic composition (206Pb/207Pb) determination in three forest soil profiles with a different prevailing type of contamination (unpolluted area, smelting area and vicinity of a motorway). The obtained results showed that all extraction/digestion methods used for the determination of 206Pb/207Pb ratios in surface horizons containing high organic matter contents gave statistically identical values (according to the Tukey test). In mineral soil horizons the differences between the individual extraction/digestion methods couldbe observed (the lowest 206Pb/207Pb ratios obtained from EDTA-extracts, corresponding to weakly bound anthropogenic lead, and the highest 206Pb/207Pb ratios obtained from total digestion). The combination of total digestion and EDTA extra
