Evaluation of extraction/digestion techniques used to determine lead isotopic composition in forest soils

Original language description

Lead isotopic studies in soils provide 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 different kinds of prevailing Pb contamination (unpolluted area, smelting area and vicinity of a motorway). The results obtained 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, differences between the individual extraction/digestion methods could be observed (the lowest 206Pb/207Pb ratios were obtained from EDTA extracts, corresponding to weakly bound anthropogenic lead, and the highest 206Pb/207Pb ratios were obtained from total digestion). The combination of total digestion and E
