“…However, previously the lead originating from leaded gasoline could have accumulated in the roadside soils over several decades. Furthermore, lead has relatively limited mobility, and therefore it can remain and become concentrated in the soils [10,[54][55][56]. These results are in good accordance with the findings of other authors, who demonstrated that lead concentrations are significantly higher in roadside soils [6,57].…”

Abstract:In the present study we examined the Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn contamination levels of the soils of Berehove, a small city in West-Ukraine. As a first step we determined the spatial distribution of the heavy metal contents of the urban soils; then, by studying the land use structure of the city and by statistical analysis we identified the major sources of contamination; we established a matrix of correlations between the heavy metal contents of the soils and the different types of land use; and finally, we drew a conclusion regarding the possible origin(s) of these heavy metals. By means of multivariate statistical analysis we established that of the investigated metals, Ba, Cd, Cu, Pb and Zn accumulated in the city's soils primarily as a result of anthropogenic activity. In the most polluted urban areas (i.e. in the industrial zones and along the roads and highways with heavy traffic), in the case of several metals (Ba, Cd, Cu, Pb, Zn) we measured concentration levels even two or three times higher than the threshold limit values. Furthermore, Cr, Fe and Ni are primarily of lithogenic origin; therefore, the soil concentrations of these heavy metals depend mainly on the chemical composition of the soil-forming rocks. Keywords

“…The clay mineral character of Boda Claystone is fundamentally illitic. Although swelling clay minerals, such as smectites and vermiculites have the largest cation exchange and adsorption capacity among clay minerals [22], illite has special sorption property for large cations with low hydration energy, such as caesium [23]. Illite and other mica-like minerals are excellent caesium adsorbents from low concentration solutions due to the presence of weathered, hydrated crystallite edges [24], the so called frayed edges.…”

Boda Claystone Formation (BCF) is the host rock of the planned site for high level nuclear waste repository in Hungary. Samples representing the dominant rock types of BCF were studied: albitic claystone, claystone with high illite content, and analcime bearing claystone. Clay minerals in these three rock types were characterized by Xray powder di raction (XRD), transmission electron microscopy (TEM) and thermal analysis (DTA-TG), and the results were discussed from the point of view of the radionuclide sorption properties being studied in the future. Mineral compositions of bulk BCF samples vary in wide ranges. In the albitic sample, besides the dominant illite, few percent of chlorite represents the layer silicates in the clay fraction. Illite is the dominating phase in the illitic sample, with a few percent of chlorite. HRTEM study revealed that the thickness of illite particles rarely reaches 10 layers, usually are of 5-6 TOT layer thick. Illite crystals are generally thicker in the albitic sample than in the illitic one. The signi cant di erence between the clay mineral characterisitics of the analcimous and the other two samples is that the former contains regularly interstratied chlorite/smectite beside the dominant illite. Based on the structural and chemical data two illite type minerals are present in the BCF samples: 1M polytype containing octahedral Fe and Mg besides Al, 2M polytype illite generally is free of Fe and Mg. Close association of very thin illite plates and nanosized hematite crystals is typical textural feature for BCF. The goal of this study is to provide solid mineralogical basis for further studies focusing on radionuclide sorption properties.

“…In this study, single element and competitive batch sorption experiments with Cu, Zn and Pb were performed on three different genetic horizons (A, B t and C k ) of a Luvisol profile. In an earlier work, Sipos [17] studied the relationship between the fractionation of native metals and sorption of added metals partly on the same samples. In this case, the aim of this study was to relate sorption parameters of the studied metals to the composition of the different horizons within the profile.…”

Abstract:The sorption parameters of Cu, Zn and Pb are related to the composition of the different genetic horizons of a Luvisol profile in batch sorption experiments. The affinities of metals towards the soil samples from different horizons followed the same sequence, e.g. Pb Cu Zn. By far the highest metal retention was found in the C k horizon due to the alkaline conditions. It is followed by the A horizon with its high organic matter content, while the lowest sorption capacity was found in the B t horizon. In the horizons free of carbonate, primarily Pb and Cu were immobilized. The studied soil can be characterized by high amount of organic matter, clay accumulation horizon, as well as calcareous subsoil. This kind of profile development makes soils able to immobilize a significant metal pollution.
