“…Many studies addressed anthropogenic contamination of alluvial sediments, including in the cases of Hackensack river [10], Paglia and Tiber rivers [11], Drava river [2], Vardar river [3], Idrijca river [12], Meža river [13] Elbe river [14] and estuarine sediments, as in the case of the Gulf of Cambay [15]. Increased levels of Cu, Zn, Cd, Ni, Cr, Hg, As and many other potentially toxic elements are commonly associated with anthropogenic impacts.…”

Stream and alluvial sediments of the Savinja and Voglajna rivers were sampled, and sediment fractions <0.063 and 0.063–0.125 mm were analyzed on the content of 60 of the main and trace elements. The objective was to determine elemental associations and identify possible sources of these associations. Differences of Al/Ti oxides ratio (9.7–26) can be attributed to the variations in the source rocks, while the K/Al oxides ratio indicates erosional or depositional river regime and variation in source rocks. One anthropogenic and three natural associations of elements were identified. The anthropogenic association (Ag, In, Sb, Cu, As, Zn, Pb, Cd, Bi, Mo and Sn) is linked to historic Zn smelting in the Celje area, and the subsequent erosion of the material from inadequately managed pyrometallurgical waste deposit. The second association (Li, Sc, Al, V, Cs and Ga) is linked to clay minerals, the third one (Mg, Ca and Te) to carbonate rocks, and the fourth one (Hf, Zr) to the heavy mineral fraction.
