Lead isotopes in lacustrine sediments and lichen transplants, contrasting and complimentary indicators of sources |
| |
Abstract: | The isotopic composition of lead has proven a powerful tool for the characterization of the types of its sources, and with other information on their identity. Lead is dispersed in the environment through water courses or airborne particulates, and has serious impact on the natural and human environments. Lake sediments record deposition derived mainly from its catchment while lichen represents the fine-grained atmospheric deposition of the site. The records of deposition differ in the scales of grain size, time and space. This investigation aims at comparing and contrasting these two types of records in an area affected essentially by a single visible emission source, and to improve the understanding of the controls on the formation of these records. The visible source is a Cu smelter complex with mining installations within the town of Karabash, in the southern Ural Mountains of Russia and considered one of the most heavily polluted areas in the world. |
