Opis:
Celem pracy była ocena zawartości sodu i potasu w wybranych glebach woj. świętokrzyskiego. W związku z narastającym problemem zasolenia gleby, w kontekście uprawy roślin, został wyznaczony przyrodniczy wskaźnik zasolenia. Zasolenie gleby negatywnie wpływa na wszystkie procesy życiowe organizmów roślinnych, ograniczając pobieranie składników pokarmowych i wody. Badaniami objęto 10 gmin województwa świętokrzyskiego o zróżnicowanej kwasowości gleby w warstwie mineralnej. Z przeprowadzonych badań wynika, że w glebie badanych obszarów występuje podwyższone stężenie sodu, które prowadzi do zastępowania potasu w roślinie. Wykorzystując wskaźnik zasolenia, określony przez iloraz zawartości sodu do potasu (Na/K), można wskazać skutki braku właściwego napowietrzenia systemu korzeniowego i przyswajalności składników pokarmowych przez rośliny.
The aim of the study was to evaluate sodium and potassium content in selected soils of Swietokrzyskie province. Due to the growing problem of soil salinity in the context of growing plants, the natural indicator of salinity has been determined. The soil salinity adversely affects all life processes of plant organisms limiting nutrient and water uptake. The study involved 10 municipalities of Swietokrzyskie province with varying acidity of the soil in the mineral layer. The study shows that the tested soil areas have an increased concentration of sodium, which leads to substitution of potassium in the plant. Using the indicator of salinity defined by the quotient of sodium to potassium (Na/K) may indicate the effects of lack of proper aeration of root system and nutrients assimilation by plants.

Opis:
The aim of this study was to evaluate the content of soil elements and parameters such as pH and iodine value in a period of one vegetation cycle. Soil samples were collected from the topsoil to a depth of 30cm, in April – before spring fertilization, August - after the summer harvest and October – before winter fertilization 2014. During the whole research period soils showed on average, a slightly acidic pH (5.6-6.2). The increase in calcium concentration leads to decrease in aluminum concentration, which at the highest content is in the range 1,02 mg/100 g and does not exceed the allowable concentration. However, increasing the sodium amount and magnesium concentration causes the decrease of potassium concentration and iodine value. In the central-eastern region dominate brown soils characterized by a lower iodine value (LJ) than in the south-western region where occurrendzina and pararendzina. The low level of nutrient microelements in studied soils obliges farmers to phosphorus fertilization and potassium supplement in order to obtain expected yields.

The aim of the study was to determine the effect of increasing doses of cobalt (0, 20, 40, 80, 160, 320 mg/kg d.m. of soil) on the total content of trace elements in soil after application of manure, clay, charcoal, zeolite and calcium oxide. The neutralizing substances were applied at 2% of the soil weight, and calcium oxide at a dose corresponding to one hydrolytic acidity. The content of the cobalt, cadmium, lead, chromium, nickel, zinc, copper, manganese and iron was determined in soil. The contamination of soil with cobalt and the application of neutralizing substances had significant effects on the total content of trace elements in soil In the series without substances, the soil contamination with cobalt increased the content of cobalt, lead, chromium, nickel and zinc in soil. All the neutralizing substances reduced the content of cobalt, manganese and iron in soil. The highest decrease in the cobalt content was observed in the series with manure, whereas the highest decrease in zinc occurred after addition of charcoal. The decrease in the content of the other metals (except nickel and lead) was observed in the pots with CaO and zeolite. The effect of other neutralizing substances depended on the trace element.

Opis:
The research consisted in the analyses pertaining to the occurrence of elements regarded as toxic (Zn, Cu, Ni, Cr, As, Pb, Cd, Hg), the presence of which in the environment is mainly associated with economic-industrial activities in mountain soils. The research area of about 5 sq. km. included the hilltops and south-western slopes of the Magurka Wilkowicka massif. The massif is situated on the western edge of the Little Beskids near the area of Bielsko-Biała city. The concentrations of elements were measured in 50 soil samples taken from three zones: at the foothill of the massif (arable fields), on its slopes (forest areas) and on the hilltop (grassland). Additionally, the pH of the soil samples was determined. The research showed that zinc and, to a lesser degree, copper and nickel, occurred in the highest concentrations at the foot of the massif, near built-up areas, while the highest concentrations of arsenic and lead were detected in the hilltop part of the grassland. The concentrations of chromium, cadmium and mercury did not differ spatially. The analysed elements, especially zinc and lead, often occurred in the concentrations higher than those regarded as natural. It is a disturbing fact combined with serious acidity of the analysed soils (almost 60% of the samples were very acid soils), which may increase mobility of metals. The research shows that the soil environment of the Polish Carpathians may be contaminated with toxic elements not only in the neighbourhood of built-up areas, but also in the undeveloped land.

Opis:
The immobilization effect of soil amendments on leaching and bioavailability of Pb, Zn and Cd in highly contaminated soils under industrial impact was studied by collecting the soils in the surroundings of Zn-Pb Smelter “Miasteczko Śląskie” in southern Poland as an example. Various amounts of four additives (phosphate fertilizer, limestone powder, bentonite rock and bog iron ore) were tested in laboratory experiments to compare the effectiveness of three dominant mechanisms of immobilization: precipitation of phosphates, pH increase, and sorption. The contents of metals before immobilization were determined by extraction in CaCl2, EDTA and aqua regia. Cadmium and zinc are mainly represented by soluble, bioavailable forms extractable in CaCl2, while lead by potentially bioavailable speciations extractable by EDTA. Most effective in the immobilization of these metals were the amendments increasing soil pH: limestone powder and phosphate fertilizer. Bog iron ore and bentonite were less effective because the soil pH was too low for efficient cation adsorption.

Long-term multipurpose geochemical studies in Lithuania show that the chemical composition of surface sediment can be used as an indicator of geological process: duration of weathering, soil formation and thickness of sediment. The chemical composition of upper and lower soil layers and of lake sediments gives information on past sedimentation: the type and age of Quaternary deposits and the location and depth of Pleistocene glaciolacustrine basins. We therefore have a baseline to predict changes in surface chemistry provoked by current anthropogenic pressures.

Opis:
The vertical distribution of the total contents assayed by Dc-Arc ES analysis of 28 trace elements and 6 major elements measured by ICP-MS within 53 complete soil profiles in Lithuania are presented. Models of the soil profiles were created, each having the master soil horizons A, E, B and C. Median values of elements in the master horizons of different texture were used in place of missing samples, while aberrant samples were discarded. The absolute average deviation () was taken to measure the variability of the data subsets and thus to check the reliability of location of the element contents within the soil profile. Within the context of the different actions of the various soil-forming processes (podzolization, lessivage, gleyfication, humification and so on) the general patterns of vertical element distribution were revealed. Element depletion is dominant in the soils of Lithuania. Themost easily removed are the alkaline elements Ca and Mg, while U, B, Th, As, Co, Cr, Sr, Y, Mo, La, Sc, Yb, Ti, P and K are depleted through the whole soil profile. Ag, Pb, Sn and Mn were defined as the accumulative elements in the surface A-horizon and might be influenced by anthropogenic or biogenic processes. A relative accumulation of Zr, Ba and Nb was observed in the surface A-horizon, and this seems to be related to the weathering of resistant minerals. Levels of Fe, Li, Al, V, Zn, Ga, Ni, Cu and Rb were ascribed to elements precipitated in the soil illuvial B-horizon due to soil formation processes. Na, K, Sr, B, U, As, Co Rb and Yb were found to be the most immobile elements within typical soil profiles, while Ag, Zn, Sc, Ba, Cu, Zr, Fe La, Th and Ca are themostmobile elements and affected by a variety of natural and human factors.

The aim of the study was to determine the long-time effect of meliorating doses of hard coal ash (0, 100, 200, 400, 600 and 800 t ha-1) on the content of some elements in soil with the application of different organic substances: manure, straw and bark. Nineteen years after the application of ash there was still an increase in the total content of all elements in soil. Its magnitude depended on soil horizon and it was highest in the humus horizon. The increase in the content of nutrients was, in general, proportional to the applied doses of ash. In the surface layer of soil, the increase was particularly high for sodium and subsequently for calcium, magnesium, sulphur, potassium and phosphorus, arranged in the order of decreasing values. The content of elements in deeper soil layers was significantly lower than in the 0–25 cm zone. A gradual reduction in the content, together with the increase in depth, was recorded only for magnesium and sulphur. The lowest concentration of phosphorus and calcium was detected in the 51–75 cm layer, while in the case of potassium it was in the 26–50 cm zone. The substances introduced into the soil in order to reduce the impact of ash generated by hard coal combustion did not exert any significant impact on the content of elements 19 years following their application.

Opis:
The objective of this study was to determine the effect of cobalt on the content of total organic carbon, total nitrogen, the available forms of phosphorus, potassium and magnesium and the C:N ratio in soil, following the application of neutralising substances. The effect of cobalt in soil was tested on oats (Avena sativa L.). In order to limit the effect of cobalt, the soil was enriched with neutralising substances, i.e. manure, clay, charcoal, zeolite and calcium oxide. In the series with no neutralising substance, the increasing doses of cobalt only caused an increase in the amount of the available potassium, and the highest Co dose favoured an increase in the organic carbon content and a wider C:N ratio in soil. All the substances affected the content of the available potassium in soil, with charcoal, and especially manure, contributing to its elevated accumulation. Besides, manure fostered a growth in the soil content of the available phosphorus, charcoal - the content of organic carbon and the available potassium, and zeolite - the total nitrogen content, while calcium oxide promoted a higher content of total nitrogen and the available phosphorus. Clay and charcoal (unlike zeolite) caused the widening of the C:N ratio in soil.

Opis:
Badania zawartości wybranych pierwiastków przenośnym spektrometrem XRF (p-XRF) są obecnie jedną z najbardziej rozwijających się instrumentalnych metod badawczych. Jego niewielkie rozmiary i waga, łatwość obsługi i szybkość wykonywania analiz umożliwiają zastosowanie spektrometru zarówno w laboratorium, jak i w pracach terenowych. Metodę wykorzystano do oznaczenia zawartości wybranych pierwiastków w glebach z rejonu góry Strużnej w Krajnie (Góry Świętokrzyskie). Do oznaczenia zawartości badanych pierwiastków zastosowano spektrometr OLYMPUS Delta X Premium (anoda tantalowa 4W, 40 kV, natężenie 200 μA, tryb ”soil”, 135 sekund). Przed rozpoczęciem analiz p-XRF był standaryzowany z użyciem materiałów referencyjnych NIST 2710a i NIST 2711a. Mapy zawartości otrzymanych dla: K, Ca, Fe, Mn, Cu, Zn, As i Pb wykonano w programie SURFER 7.0 z wykorzystaniem procedury krigingu. Zarówno dobra zbieżność średnich zawartości uzyskanych dla badanego obszaru w porównaniu ze średnimi wartościami dla gleb Gór Świętokrzyskich, uzyskanymi wcześniej przez różnych autorów z zastosowaniem standardowych wówczas metod analizy chemicznej, jak również dobra zgodność rozkładu zawartości badanych pierwiastków z budową geologiczną rejonu góry Strużnej pozwalają stwierdzić, że wybrana metoda fluorescencji rentgenowskiej jest odpowiednia dla tego typu badań. Wysoka dokładność uzyskanych oznaczeń z użyciem spektrometru p-XRF Olympus Delta X dowodzi, że urządzenie to jest efektywnym narzędziem zarówno dla prac środowiskowych, jak i geochemicznych.
The analysis of chemical composition using the portable X-ray fluorescence spectrometer (p-XRF) is recently rapidly developing instrumental research method. This method was applied to analyze the content of selected elements in soil samples from the Strużna region of the Holy Cross Mountains. The Olympus Delta Premium p-XRF spectrometer (4W Ta anode X ray tube, 40 kV, 200 μA current beam, “soil” mode, 135 seconds) was used. Prior to analyze the soil samples, the NIST 2710a and NIST 2711a reference standards were utilized in order to calibrate the p-XRF spectrometer. The maps showing obtained results of K, Ca, Fe, Mn, Cu, Zn, As and Pb were constructed using the SURFER 7.0 software with kriging procedure. The obtained results show arithmetic means similar to the previously obtained using traditional methods of chemical analysis for the soils of Holy Cross Mountains. These results combined with the high accuracy of measurements obtained by using the p-XRF Olympus Delta X spectrometer proved this device to be the effective tool for environmental and geochemical studies.

Opis:
Nonlinear soil-linear structure computational strategy is commonly accepted in the community of geotechnical engineers using advanced finite element software for solving complex soil-structure interaction problems. However, further design procedure of the structural elements is carried out using increased values of the computed elastic stress resultants. It is absolutely not clear whether this method is conservative and, therefore, whether safe or not. To tackle this problem, a fully consistent nonlinear analysis of a deep excavation protected by the diaphragm wall is analysed here. The subsoil is modelled using the Hardening Soil model, while reinforced concrete is modelled using the modified Lee-Fenves model enhanced by the Eurocode 2 (EC2)-compatible creep module, developed by the author. It is shown that the commonly used nonlinear soil-linear structure computational strategy may yield insufficient amount of reinforcement from the ultimate limit state (ULS) and serviceability limit state (SLS) points of view. A consistent and conservative method of combining fully nonlinear analysis and the rules imposed by the EC2 is proposed.

Opis:
Red basil (Ocimum basilicum L.) cv. Red Rubin was cultivated in model pot experiment in the soil amended by arsenic, cadmium and lead solutions in stepwise concentrations representing the soil concentration levels of former mining area in the vicinity of Příbram, Czech Republic. The element levels added to the soil reached up to 40 mg Cd, 100 mg As, and 2000 mg Pb per kg of soil. Moreover, essential macro-and microelements as well as cyanidine contents were investigated to assess their potential interactions with the risk elements. The extractable element portions in soils determined at the end of vegetation period differed according to the individual elements. Whereas the plant-available (extractable with 0.11M CH3COOH) content of Cd represented 70-100% of the added Cd, the mobile portion of Pb did not exceed 1%. The risk element content in plants reflected the increasing element contents in soil. The dominant element portions remained in plant roots indicating the limited translocation ability of risk elements to the aboveground biomass of this plant species. Although the risk element contents in amended plants significantly increased, no visible symptoms of phytotoxicity occurred. However, the effect of enhanced risk element contents on the essential element uptake was assessed. Considering inter-element relationships, elevated sulphur levels were seen in amended plants, indicating its possible role of phytochelatin synthesis in the plants. Moreover, the molybdenum contents in plant biomass dropped down with increasing risk element uptake by plants confirming As-Mo and Cd-Mo antagonism. The increasing content of cyanidine in the plant biomass confirmed possible role of anthocyanins in detoxification mechanism of risk element contaminated plants and suggested the importance of anthocyanin pigments for risk element tolerance of plants growing in contaminated areas.

Opis:
The increasing demand for noble metals boosts their price. In order to meet the increasing demand for elements, a number of technologies are being developed to recover elements already present in the environment. Traffic-related metal pollution is a serious worldwide concern. Roadside soils are constantly subjected to the deposition of metals released by tailpipe gases, vehicle parts, and road infrastructure components. These metals, especially platinum group elements from catalytic converters, accumulating in the soil pose a risk both for agricultural and residential areas. Phytomining is suggested as a novel technology to obtain platinum group metals from plants grown on the contaminated soil, rock, or on mine wastes. Interest in this method is growing as interest in the recovery of rare metals is also increasing. Based on the research of many authors, the sources and amounts of noble metals that accumulate in soil along communication routes have been presented. The paper presents also plants that can be used for phytomining.
Aby sprostać rosnącemu zapotrzebowaniu na metale szlachetne poszukuje się technologii odzyskiwania pierwiastków już obecnych w środowisku. Gromadzące się w glebie metale, zwłaszcza pierwiastki z grupy platynowców pochodzące z katalizatorów, stanowią zagrożenie dla środowiska. Fitoekstrakcja jest technologią wykorzystywaną do pozyskiwania metali z grupy platynowców z roślin rosnących na zanieczyszczonej glebie, skale lub odpadach kopalnianych. Zainteresowanie tą metodą rośnie wraz ze wzrostem zainteresowania odzyskiem metali rzadkich. Na podstawie wyników badań różnych autorów przedstawiono ilości metali szlachetnych gromadzących się w glebie wzdłuż szlaków komunikacyjnych. W pracy przedstawiono także rośliny, które można wykorzystać do fitoekstrakcji.

Opis:
Soil contamination with rare earth metals (REE) can have both direct and indirect connection with industrial activity and ore-exploration. In the studies conducted so far, the presence of rare earth elements in coal seams, coal combustion waste as well as fly ash was found. It is important that detailed studies of the REE content in soil were not carried out in Poland. Until now, in a few studies, a high content of cerium and lanthanum was found in relation to the average content of the torn ones in the world. This work focuses on the areas under the influence of the industry associated with the extraction and combustion of hard coal, but also with other types of industry. Analyzes of REE content in soil were conducted in selected areas of the Upper Silesian Industrial Region and Norway, located near the Bjornevatn mine. In study areas, soil samples were collected and used for chemical and magnetometric measurements. Firstly, concentrations of REE were determined, and after that soil samples were used to measure soil magnetic susceptibility. Finally, statistical analyses were performed in order to check the correlation between REE concentrations in soil and soil magnetic susceptibility.
