Stratigraphic characteristics of quaternary deposits on the left bank of the Sava River near Belgrade

Quaternary deposits on the banks of the Sava River in the Belgrade area have a significant thickness and they are represented by genetically different formations. The data about these sediments were obtained by exploration of two relatively shallow boreholes, RB 47/P-1 and RB 53/P-1, located on the left bank of the Sava River. Two genetic entities are distinguished: the lacustrine-palustrine deposits of Plio-Pleistocene age and alluvial deposits of Pleistocene and Holocene age. Deposits of the Plio-Pleistocene are clearly different, both lithologically and palaeontologically, from the overlying alluvial deposits. Lithologically similar fluvial deposits of the Pleistocene and Holocene age were distinguished according to their palaeontological characteristics, particulary by the presence of bivalve genera Corbicula and Dreissena.

The Sava River

The largest single-pylon, cable-stayed bridge in the world was opened in Belgrade on January 1, 2012 and it passes over the tip of the Ada Ciganlija Island. Its monumentality, architectural design and construction innovations became a new symbol of Belgrade. Core samples from the boreholes drilled for the construction of the bridge revealed a relatively complex subsurface geological structure. An Upper Cretaceous-Paleogene flysch formation and Middle Miocene Sarmatian sediments were found near the surface on the right bank of the Sava River. However, at the tip of Ada Ciganlija, the Upper Cretaceous-Palaeogene flysch strata were found below several different Miocene and Quaternary units. In the deepest borehole DB-6, the flysch deposits were found at a depth of 80 meters. On the left bank of the Sava River in New Belgrade, only Upper Miocene Pannonian marls and Pleistocene and Holocene alluvial deposits were drilled. Based on a comparative analysis of the borehole sections and structural characteristics of the rocks, it could be concluded that the Pre-Quaternary units cascade subsided along sub-parallel faults towards N-NW.

Outcrops of Quaternary deposits are lining banks of the Brno dam. One of them is situated on the left bank ~ 250 m NW of the Osada pier. The sedimentary profile of Pleistocene deposits is composed of fluvial deposits of the Paleo – Svratka River covered by colluvial and eolian (loess) deposits. Alternation of various facies and various grain-size fractions reveals alternation of more or less arid conditions and also evolution of the surrounding landscape.

The applicability of nitric acid, palladium nitrate and a mixture of palladium and magnesium nitrate as matrix modifiers was estimated for the accurate and reproducible determination of cadmium (Cd), lead (Pb) and arsenic (As) in sediments of the Sava River by electrothermal atomic absorption spectrometry, ETAAS. Decomposition of the samples was done in a closed vessel microwave-assisted digestion system using nitric, hydrochloric and hydrofluoric acids, followed by the addition of boric acid to convert the fluorides into soluble complexes. The parameters for the determination of Cd, Pb and As in sediments were optimized for each individual element and for each matrix modifier. In addition, two sediment reference materials were also analyzed. In determination of Cd and Pb, nitric acid was found to be the most appropriate matrix modifier. The accurate and reliable determination of Cd and Pb in sediments was possible also in the presence of boric acid. The use of a mixture of palladium and magnesium nitrate efficiently compensated for matrix effects and enabled the accurate and reliable determination of As in the sediments. Quantification of Cd and As was performed by calibration using acid matched standard solutions, while the standard addition method was applied for the quantification of Pb. The repeatability of the analytical procedure for the determination of Cd, Pb and As in sediments was ?5 % for Cd, ?4 % for Pb and ?2 % for As. The LOD values of the analytical procedure were found to be 0.05 mg/kg for Cd and 0.25 mg/kg for Pb and As, while the LOQ values were 0.16 mg/kg for Cd and 0.83 mg/kg for Pb and As. Finally, Cd, Pb and As were successfully determined in sediments of the Sava River in Slovenia.
