Atmospheric Pb deposition in four national parks in Poland as determined by Pb isotope ratios
We determined the <206>pb/<207>Pb and <206>pb/ <204>Pb isotope ratios in selective extracts and total extracts of soils from four national parks in Poland. Soils in all of the national parks in this study contain Pb isotope ratio signatures indicative of anthropogenic Pb. Isotope signatures recorded from soil samples taken within Biesczcady and Roztocze National Parks indicate that anthropogenic Pb is dominant. Soil samples from Poleski National Park show mostly Pb isotope signatures indicative of anthropogenic Pb in surface samples, while most subsurface samples contain Pb isotope signatures consistent with natural Pb. In the Tatry National Park, a majority of the total and sequential chemical extraction Pb isotope ratios recorded indicate anthropogenic input. In soil samples that portrayed natural total Pb isotope signatures, there were still anthropogenic Pb isotope signatures present in the more easily soluble geochemical phases. Data from this portion of the study is consistent with the postulate that elevated amounts of Pb in the more easily soluble geochemical phases relative to the less soluble phases indicate anthropogenic input.
