AB  - The aim of this study was to assess the spatial distribution of arsenic and heavy metals (Cd, Cr, Cu Hg, Ni, Pb and Zn) in a riparian area influenced by periodical flooding along a considerable stretch of the Danube River. This screening was undertaken on soil and plant samples collected from 43 sites along 2386 km of the river, collected during the international Joint Danube Survey 3 expedition (ICPDR, 2015). In addition, data on the concentration of these elements in river sediment was used in order to describe the relationship between sediment, riparian soil and riparian plants. A significant positive correlation (Spearman r, for p  LT  0.05) was found for trace metal concentrations in river sediment and soil (r = 0.817). A significant correlation between soil and plants (r = 0.438) and sediment and plants (r = 0.412) was also found for trace metal concentrations. Elevated levels of Cd, Cr, Cu, and Ni were found at certain sites along the Serbian stretch, while elevated concentrations of Hg were also detected in Hungary, of Pb along the Romanian stretch and of As along the Bulgarian stretch (the Lower Danube). These results point to the presence of naturally-occurring metals derived from ore deposits in the Danube River Basin and anthropogenic metals, released by mining and processing of metal ores and other industrial facilities, which are responsible for the entry of metals such as Cu, Ni and Zn. Our results also indicated toxic Cd and Zn levels in plant samples, measured at the Hercegsznato site (Middle Danube, Hungary), which highlighted these elements as a potential limiting factor for riparian vegetation in that area. The distribution of the analysed elements in plant material also indicates the species-specific accumulation of trace metals. Based on our results, the Lower and Middle Danube were found to be more polluted in terms of the analysed elements.

AB  - Hydrogen adsorption on single-crystal platinum low-index and stepped surfaces was studied in 0.1 M and 0.01 M NaOH solutions. A strong dependence on the crystallographic orientation of the electrode surface was found. The multiple states of hydrogen were correlated with the symmetry of surface sites. The data for the stepped surfaces were found to be useful in explaining the nature of processes occurring on the low index surfaces. Several strong indications were found for the nature of the so-called "butterfly" peak, indicating that it is due to adsorption of the hydroxil species rather than to hydrogen adsorption. Indications for hydrogen adsorption on Pt(111) in the H2 evolution region was found by impedance measurements. An effort was made to identify the multiple adsorption states for Pt(100). Hydrogen adsorption on the step sites for surfaces from all three crystallographic zones was identified and found to be proportional to the step density. A comparison with hydrogen adsorption in acid solutions was made for some surfaces.

AB  - Hydrogen and bisulphate adsorption at platinum single crystal surfaces from the [ITO] zone is
strongly dependent on the crystallographic orientation of the electrode surface, which is similar to that
found earlier for the [llO] zone. For the purposes of comparison, some experiments were performed with
non-adsorbing perchlorate acid solutions. The multiple states of hydrogen adsorption can be correlated
with symmetry of surface sites and the nature of the adsorbed oxi-anions. All stepped surfaces
investigated from this zone have one sharp peak at -0.175 V which is due to a coupled desorption of
bisulphate and hydrogen adsorption from the sites with the (110) symmetry. The surfaces of the
n(llO)-(lll) type behave as the surfaces denoted (n -1X110)-3(111) since the three atom long terrace is
“seen” by bisulphate and hydrogen.
Bisulphate anions are more strongly adsorbed at the steps than at the (111) oriented terraces, The
latter process occurs at more positive potentials than the adsorption at steps and it is affected by anions
at the step sites. The structure in the electrolyte solutions has been discussed.

AB  - The oxidation of ethylene glycol (EG) has been studied on platinum single-crystal surfaces in 0.1 M NaOH. A strong structural dependence of the reaction kinetics was found for all 12 single-crystal orientations investigated. The onset of the reaction occurs in the sequence Pt (110) > Pt (100) ≈ Pt (111). However, the peaks of the voltammetry curves for the low-index planes decrease in the order (111) > (110) > (100). Either the (111) or the (100) oriented steps cause a decrease in the activity of the (111) plane. Surfaces vicinal to the (100) plane exhibit a higher activity than Pt (100). The (111) oriented steps in the Pt (110) plane cause an increase in activity, while the (100) oriented steps decrease it. A parallelism between PtOH layer formation and the onset of the oxidation of EG was found which indicates that the reaction involves interaction of the adsorbed and dehydrogenated EG with Pt(OH)ads species.

AB  - The adsorption of hydrogen and sulphuric acid anions has been studied on single-crystal platinum stepped surfaces from the [110] zone. Both processes depend on the orientation of the electrode surface. The multiple states of hydrogen adsorption can be correlated with the nature and density of the adsorption sites. There is a negligible effect of adsorbate-adsorbate interaction. The voltammetric profiles are in a wide potential range determined by bisulphate and sulphate adsorption/desorption. A sharp peak found in voltammetry is associated with hydrogen adsorption in the step sites, composed of the (100)-(111) step-terrace combination, concurrent with sulphate desorption. Bisulphates and sulphates are strongly adsorbed in the trigonal sites in the step, which can be formed from the steps and terraces of different orientations from this zone. The exact position of the adsorbed hydrogen atoms and anions is discussed. A comparison with the adsorption in HClO4 is given for some surfaces.
