Abstract:

Tracing the sources of metals in the environment is an important key in our understanding of their biogeochemical cycling and the pollution pathways. Cadmium species are among the most toxic and harmful environmental contaminants, so tracing its sources is a very important and useful tool. In this study soil samples were collected from the heavily industrialized region of Ostrava Upper Silesia Czech Republic. Matrix separation methodology was optimized in order to separate pure cadmium fraction from the soil samples for further isotopic analysis. Concentration of selected metal(loid)s was determined to evaluate the level of contamination in the Ostrava region. Finally matrix separation efficiency was determined to evaluate if it is a suitable method for Cd separation from environmental samples prior the isotopic analyses. The Cd separation was proved to be an efficient and suitable method for further isotopic analysis of soil samples the separation efficiency was usually over 95%.
