Anthropogenic Lead Deposition and Four National Parks in Poland as Determined by Lead Isotope Ratios

<p>Polluted soils are recognized by having high concentrations of heavy metals, including Pb. Partitioning of metals in geochemical fractions, by sequential chemical extractions, may indicate whether a metal has been recently deposited in the soil. While concentration levels alone cannot distinguish between natural and anthropogenic Pb, studies have demonstrated that anthropogenic pollution is accurately recorded by specific Pb isotope signatures, which differ from natural Pb isotopes. The objective of this project was to use ²⁰⁶Pb/²⁰⁷Pb and ²⁰⁶Pb/²⁰⁴Pb isotope ratios to differentiate between the anthropogenic Pb input and the naturally occurring Pb in four national parks in Poland. A second goal was to test the postulate that sequential chemical extractions could be used to evaluate the pollution status of the soils. Soils from Tatry National Park underwent sequential chemical extractions and total acid extractions, while soils from Biesczcady National Park, Roztocze National Park, and Poleski National Park underwent total acid extractions.</p>
