Abstract
The Pb contents and 206Pb/ 207Pb and 208Pb/ 206Pb isotopic ratios were studied in the soils and wines (2004 harvest) of three vineyard areas of the Czech Republic. The areas differ in their geological basements and anthropogenic loading. The isotopic compositions of wine in areas with intensive industry (Most, North Bohemia 206Pb/ 207Pb wine = 1.178 ± 0.004) and the agricultural areas of Central Bohemia (Roudnice nad Labem 206Pb/ 207Pb wine = 1.176 ± 0.007) are similar to the Pb isotopic composition of airborne particulate material typical of polluted and industrial environments ( 206Pb/ 207Pb = 1.17–1.19). The isotopic composition of wine from Prague ( 206Pb/ 207Pb wine = 1.174 ± 0.003) is different from that of the soil, which was severely contaminated in the past by vehicular Pb ( 206Pb/ 207Pb soil = 1.147–1.168). This fact shows that interception of airborne Pb by plants is greater than its uptake by the root system.
