abstract = {The use of phyllite (Phy) instead of quartz in mixtures with bentonite (B) is recommended as a buffer material for engineering barriers in a geological repository of nuclear waste. The recommendation is based on experimentally determined sorption properties of various Phy/B mixtures. The adsorption capacity of Phy/B mixtures (Phy/B: 75/25; 50/50; and 25/75), the removal efficacy of Eu(III) ions (an analog for fissiongenic lanthanides and actinides), and the rate of their binding reaction were studied using the batch adsorption equilibrium and kinetic experiments at different Eu(III) initial concentrations, solution pH, and solution to adsorbent (L/S) ratio. The adsorption capacity of the Phy/B mixtures increased with the increased bentonite content in the mixture depending on the L/S ratio and solution pH. The highest increase in the adsorption capacity of the Phy/B mixtures compared to phyllite was observed for the Phy/B proportions of 25/75 and 50/50. The rate of the Eu(III) adsorption was the best fitted by the pseudo-second-order kinetic model indicating that the adsorption rate was controlled by chemisorption. The Sips model provided the best correlation of the adsorption experimental data, indicative of more than one adsorption site. The results of this study show the advantage of the Phy/B mixtures in immobilizing Eu and certain fission products by combining adsorption properties of the materials. © 2023. The Author(s).},

abstract = {This study aims at detailed characteristics and comparison between dusts from various iron and non-ferrous metal production processes in order to identify individual mineral phases, chemical composition, and their influence on the values of magnetic susceptibility. Various analytical methods used include inductively coupled plasma optical emission spectroscopy, X-ray diffrac-tion, scanning electron microscopy, and Mössbauer spectroscopy integrated with magnetic susceptibility measurements and thermomagnetic analysis. Metallurgical wastes that have arisen at different production stages of iron and non-ferrous steel are subjected to investigation. The analyzed dust samples from the iron and non-ferrous metallurgy differ in terms of magnetic susceptibility as well as their mineral and chemical composition. The research confirmed the presence of many very different mineral phases. In particular, interesting phases have been observed in non-ferrous dust, for example challacolloite, which was found for the first time in the dusts of non-ferrous metallurgy. Other characteristic minerals found in non-ferrous metallurgy dusts are zincite, anglesite, and lanarkite, while dusts of iron metallurgy contain mostly metallic iron and iron-bearing minerals (magnetite; hematite; franklinite; jacobsite; and wüstite), but also significant amounts of zincite and calcite. © 2021 by the author.

abstract = {Disposal of radioactive wastes in underground repositories necessitates knowledge on adsorption and mobility of radionuclides in host rocks (geologic barrier) and in engineered barriers, including clay barrier. The batch adsorption of Eu(III) (a homologue for trivalent radionuclides) onto phyllite compared to bentonite was studied as a function of solution pH (4.5 and 7.0), solution to clay rock ratio (10:1; 100:1; 500:1 and 1000:1), and various Eu(III) concentrations (0.01–190 mg/L; 0.658 × 10−7–1.25 × 10−3 M). The experimental data were interpreted using the isotherm models of Langmuir, Freundlich, Dubinin-Radushkevich, Tóth, and Sips. Adsorption/desorption experiments and bonding strength calculations showed that the adsorption behavior depends on the mineral composition of sorbents, solution pH, the initial concentration of Eu(III), and liquid: solution ratio (L:S). The cation exchange within the interlayer space of montmorillonite is the main adsorption mechanism in bentonite. Cation exchange on the minerals surface, chemical reactions leading to the precipitation of new phases, the electrostatic effect at a low initial concentration of Eu (III), and pH > pHPZC are adsorption mechanisms in phyllites. Solution pH has a pronounced effect on the Eu(III) adsorption onto phyllite due to surface protonation. Fe-oxides and hydroxides play a significant role in the adsorption/desorption of Eu(III) on phyllites. The best fitting was obtained for three-parameter isotherm models of Sips and Tóth. The mechanism of Eu(III) binding is complex and does not follow the ideal monolayer adsorption. While the maximum adsorption capacity of phyllite is 2.5 to 6.6 times lower than of bentonite, depending on the solution pH, it is high enough to guarantee efficacious and durable removal of actinides from the contaminated solutions, particularly at their low concentrations. Phyllites adsorption and mechanical properties make them suitable additives to bentonite in a clay barrier. © 2019 Elsevier B.V.},

abstract = {The research was carried out around dumps made at the beginning of twentieth century linked to Zn-Pb ore mining of deposits of Mississippi Valley type in Southern Poland. Soil algae communities were investigated near spoil dumps rich in Zn, Pb, Fe, Cd, and Tl. In algal crusts, Chlorophyta and Cyanophyta occur in filament forms such as Stichococcus bacillaris, Stichococcus chlorelloides, S. cf. fragilis, and Cylindrocapsa sp. The algal crusts form aggregates containing metal-bearing minerals and algal organic material. The development of the crusts occur on sandy-clayey soils poor in water and highly enriched in heavy metals (up to 68;800 mg kg-1 for Zn; 85;060 mg kg-1 for Pb; 369 mg kg-1 for Cd and 355 mg kg-1 for Tl). Algal-crust formation is an important initial stage which facilitates vascular plant succession and topsoil formation. The results of investigation of algal material with ESEM are presented and the mineral phases in the top soil layer based on the XRD and EDS are described. The results indicate the presence of secondary labile minerals of lead, e.g., anglesite and plumbojarosite and minerals of Zn, e.g., smithsonite and minrecordite. © 2010 Springer Science+Business Media B.V.},

abstract = {The potential use of dust particles trapped on Scots pine needles for tracking dust migration around flotation tailings ponds in the Silesian-Krakowian ore district, Southern Poland was tested. 1-, 2- and 3-years old needles were studied using a scanning electron microscope and energy dispersive X-ray microanalysis. Particle sizes and morphologies, and the nature of the compounds hosting metals ions, were examined. A large majority of the particles examined are <10 μm in size. Almost 80% of particles represent respirable dust. All the components in the flotation wastes appear among the chemical compounds identified in particles on the pine needles. The quantity of the waste particles decreases with distance from the flotation tailings ponds. The analysis of dust particles on pine needles could be a useful method for estimating vectors and travel distances of suspended dust migrating around open flotation tailings ponds and around other point sources emitting dust particles with chemical compositions differing from the environmental background. © Springer Science+Business Media B.V. 2008.},

Samples of substrates and plant roots were taken from sites in the Bolesław orefield near Olkusz. The substrates together with plant roots were studied by scanning electron microscopy coupled with energy dispersive spectroscopy. Apart from quartz and carbonates, the most frequent mineral phases found were crystalline and amorphous Fe oxides, as well as primary Fe, Zn and Pb sulphides (marcasite; pyrite; sphalerite; galena). Hydrated Ca, Mg and Fe sulphates (gypsum; epsomite and melanterite) and other secondary minerals (smithsonite; cerussite; otavite; and Fe; K and Mg aluminosilicates) were found at larger concentrations in the rhizosphere than in bulk soil, suggesting that plant roots can change the mineral composition of the soil. © Polish Academy of Sciences, Cracow 2004.},
