Distribution of chemical elements in attic dust and soil as reflection of lithology and anthropogenic influence in SloveniaR. Sajn
Geological Survey of Slovenia, Dimiceva 14, 1000 Ljubljana, Slovenia
The aim of this study was to establish contents and distribution of chemical elements in attic dust in Slovenia, and to define them according to geology and anthiopogenic influence. Attic dust and topsoil (0-5 cm) samples were collected in the rural area in settlements without known industry and in six largest towns in Slovenia. Analysis of 42 chemical elements was performed. For estimation of the association between elements and sampling materials the R mode factor analysis was applied. Al, Ba, Co, Ci, Fe, La, Mn, Na, Nb, Ni, Sc, Th, Ti, Y, V and Zr in attic dust reflect the natural distribution. The highest elemental contents in attic dust occur in the areas of igneous and metmoiphic rocks and of flysch formation. High contents of the elemental association Co, Ci, Fe, Mn, and Ni reflect also centuries of ferrous metallurgy. Distribution of As, Cd, Cu, Hg, Mo, Sb, Sn, Sr, Pb and Zn represents the anthropogenically introduced chemical elements. Their averages in attic dust are higher compared to topsoil. High contents of these elements are a result of historical Pb-Zn mining and smelting.
