A record of anthropogenic lead deposition in a Mediterranean karst catchment (Lake Vrana, Cres Island, Croatia)

To trace the history of anthropogenic, atmospheric lead pollution, analysis of soils from the region as well as cores from the karst Lake Vrana (croat. Vransko jezero) on the island of Cres were performed. The area affected Pb pollution in Croatia covers most of the high mountain karst region. Since lake sediments can act as archives of atmospheric deposition of metals (and other pollutants) a multi-element analysis as well as Pb isotopes of dated sediment core samples and paleosoil from the catchment allowed the evaluation of Pb pollution history. The Pb/Sc ratios and the 206Pb/207Pb ratios allowed the calculation of enrichment factors and the anthropogenic contributions of Pb during the past 4000 years. The sediments of Lake Vrana where found to be an consistent record of lead pollution in this part of the Mediterranean region, despite the fact that the catchment lost most of its soil cover between 1404 and 1650 AD due to deforestation which caused a major change in sediment composition.
