AB  - The aim of this study was the evaluation of the trace element contamination level in sediments of the most important rivers in Serbia and their tributaries. The determination of the aqua regia soluble contents of 12 micro- and macro-elements (Ca, Cd, Co, Cr, Cu, Fe, Mn, Pb, Ni, Zn, Be and V) in sediments was developed by the microwave digestion technique combined with inductively coupled plasma atomic emission spectrometry. Correlation analysis and principal component analysis distinguishes factors of lithogenic and anthropogenic origins. The Fe, Mn, Be and V contents are controlled by a regional lithogenic high background factor, while Cd, Cr, Pb, Ni, Zn and Cu are recognized as tracer of pollution. For Co, mixed sources from both lithogenic and anthropogenic inputs were evidenced. The investigated sediment of the major rivers and their tributaries in Serbia showed high concentrations of metals, especially of Cd, Pb, Cu and Zn, which may cause serious environmental impacts. Rivers which flow into the Danube from its entrance into Serbia significantly influence the chemical load of the water and sediments. The experimental study was conducted using two BCR standard reference materials. The calculated accuracy and precision confirmed the good performance of the adopted procedures.

AB  - Surface and buried sediments were analyzed for Ba, Ca, Cd, Co, Cr, Cu, Mn. Ni, Pb, Zn and V. as well as for total carbon and hydrogen to assess the distribution of sediment pollution due to the vicinity of the petrochemical complex. The samples, collected from 20 locations within the petrochemical complex and from 16 locations outside the complex, were aqua regia extracted and analyzed by ICP/OES. Metals were determined with an acceptable accuracy for certified metals of 82-113%. The precision for the aqua regia extraction was satisfactory, less than 20%, except for Cd where it was 28%. Comparison of the data from the petrochemical with those from the non-petrochemical areas showed different distributions of the metals. Metals that exceeded the baseline range; Ba, Cd, Cu, Zn and Pb, were detected in higher concentrations in sediments that were under the influence of the chlor-alkali plant within the petrochemical complex. Comparison with data from the petrochemical complex and its surroundings and their distribution demonstrated that the metal compositions of the sediments were modified by anthropogenic activities.

AB  - Two used digestion procedures: microwave aqua regia and microwave aqua regia plus HF, were compared for digestion of 2 standard references material and 36 surface and burial sediments within an industrial area in Pandevo. Samples collected at 20 locations within petrochemical and at 16 locations in near by non-petrochemical area and were extracted and analyzed by ICP/OES. Ten elements such as: Ba, Cd, Cu, Cr, Mn, Fe, Ni, Pb, V and Zn were analyzed. Accuracy was also acceptable for certified metals in aqua regia plus HF being 78-110 % except for Pb iii BCR 143 R standard where it was 172 %. Accuracy for certificated metals in aqua regia digestion was acceptable by being 80-113%. Precision for aqua regia with HF were less than 5 %, while for aqua regia was little bit higher but less than 10 %, except for V where it was 12 % and for Cd it was 28 %. The aqua regia with HF has slightly better precision than the simple aqua regia.
