Lead and lead isotopes in agricultural soils of Europe - The continental perspective

Lead isotope are widely used for age dating, for tracking sources of melts, sediments, Pb products, food and animals and for studying atmospheric Pb contamination. For the first time, a map of a Pb isotope landscape at the continental-scale is presented. Agricultural soil samples (Ap-horizon, 0-20cm) collected at an avearge density of 1 site/2500 km2 were anlysed for Pb concentration and Pb isotopes (206Pb, 207Pb, 208Pb). Lead concentrations vary from 1.6 to 1309 mg/kg, with a median of 16 mg/kg. Isotopic ratios of 206Pb/207Pb range from 1.116 to 1.727 with a median of 1.202. The new data define the soil geochemical Pb background for European agricultural soil, providing crucial information for geological, environmental and forensic scineces, public health, environmental policy and mineral exploration. The European continental-scale patterns of Pb concentrations and Pb isotopes show high variability dominated by geology and influenced by climate. Lead concentration anlomalies mark most of the known mineralised areas throughout Europe. Some local Pb anomalies have distinct anthropogenic origin.
