Opis:

Cassiterite and base-metal mineralisation from the Gierczyn mine on the Karkonosze-Izera Massif, Poland has been studied using electron microprobe and LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) techniques in order to determine the content of indium in the ore minerals. The main carriers of this element are sphalerite (up to 433 μ/g of In), chalcopyrite (up to 117 μ/g of In) and cassiterite (up to 0.02 wt.% In). Trace element contents of sulphides, especially Ga in chalcopyrite intergrown with sphalerite in comparison with chalcopyrite without sphalerite, may indicate metamorphic re-equlibration and suggests that the ore minerals might recrystallized and underwent metamorphism in conditions of greenschist/amphibolite facies. Although the deposits in the Stara Kamienica Schist Belt are not of economic value, they can contribute to better understanding of the relations between trace element partitioning and the formation of ore minerals.

Opis:

Bituminous to anthracite coals from three small Stephanian intramontane coal-bearing basins (La Magdalena, Cinera-Matallana and Sabero) located along the Sabero-Gordón fault line strike-slip systems of the Southern Cantabrian Zone (SCZ) were examined. Coal rank expressed as mean vitrinite reflectance values of these Stephanian coals is in the range 0.72-3.96%. The vitrinite maceral group exceeds 72 vol. % in all of the coals. The coals are characterized by relatively variable contents of mineral matter and coal-ash. The mineral matter comprises, in the main, clay minerals, carbonates, sulphides and quartz. The coals exhibit medium-high concentrations (see for comparison Ronov et al. 1990; Kabata-Pendias, Pendias 1999; Ketris, Yudovich 2009) of the following elements (in ppm): ΣREE (53-205), Ba (300-900), As (11-57), Zn (<50-150), Cr (10-160), Rb (50- 145), Co (5-26), Sc (2-24.6), Ce (17-99), Yb (1.3-4.5), Th (2.4-11.9) and U (1.1-8.1), Br (<1-14), Cs (<2-9), Eu (<0,3-1.5), Lu (0.11-0.85) and Sb (0.8-4.8), and relatively low concentrations of Sm (0.6-6.6) and Ta (<1-2). They are also characterised by relatively high Th/U values (1.31-2.29). LREE/HREE values fall in the range 24-44 (average - 30). In contrast, concentrations of Au, Ag, Hg, Ir, Ni, Se, Sn, Sr, and W are below detection limits for the applied INAA method. As the concentrations of elements are significantly higher in coal-ash, most are likely related to mineral matter in the coals.

The study shows the content of macro- and microelements in the leaves and rhizomes of Glyceria maxima of the Słupia River in Słupsk. The content of macro and micro-elements in G. maxima was analyzed for each component separately and in an integrated way, and comparing the demand for nutritions. The largest quantity of nitrogen, phosphorus, potassium, magnesium and calcium were found in the leaves, meanwhile zinc, iron, manganese, nickel and copper in the G. maxima rhizomes. The amount of Zn and Cu, in all of the tested positions, within the range of the limit for the plants, and the concentrations of Ni and Mn exceed physiological needs. The U Mann Whitney test showed a number of statistically significant differences in the concentration of the analyzed elements in leaves – rhizomes, leaves – bottom sediment and rhizome bottom sediment relation. The relations between designated heavy metals formed a following series: Mn>Fe>Zn>Ni>Cu in leaves and Fe>Mn>Zn>Ni>Cu in rhizomes. The G. maxima shoots accumulated 985.8 do 1441.4 mmolc∙kg-1 in all the analyzed components, and the lower value of the sum of the accumulated macro and microelements were found in rhizomes. The sum of ion comospition of the macronutrients in the leaves and rhizomes was similar. The content of nitrogen was 51.7–53.7% of this amount, 5.8–8.6% phosphorus, potassium 22.8 – 26.6%, 4.9-5.8% of magnesium, calcium, 8.2–11.9%, and trace elements were 0.58% in total, in the case of leaves and 8.70% in the rhizomes.

Opis:

Tectonic setting of both the uppermost Triassic Tomanová and the lowermost Jurassic Dudziniec formations can be characterized by a series of diagnostic discrimination diagrams. High-silica and low-silica multi-dimensional diagrams indicate that the sediments could have been deposited in the continental collision/rift setting. Diagrams of K2O/Na2O versus SiO2, SiO2/Al2O3 versus K2O/Na2O and Th-Co-Zr/10 as well as Th-Sc-Zr/10 determine an origin from the tectonically active and/or passive continental margin setting. REE parameters indicate predominantly a passive margin tectonic setting of the sediments. The most probable source of clastic admixture in the Scythian to Domerian sediments in the Tatric Unit was situated in a remnant of the Variscan collisional orogen - the Vindelician Highlands. Occasional monsoonal rains occurring in orbitally controlled cycles transported weathered material from the source area down river valleys on the seaward slopes of the Variscan Vindelician Mountains towards the Tethyan Sea. The input of this material influenced also the marginal parts of the Fatricum (e.g., Vysoká or Havran units).

Opis:

A forecast of the negative impact exerted on the environment by selected trace elements in "Bełchatów" Power Plant has been prepared on the basis of the results of investigations into these elements’ distribution carried out as part of earlier research on coal from “Bełchatów” Field and the data on updated analyses of the content of these elements in 55 brown coal samples from test boreholes. Work in "Bełchatów" Power Plant, which is supplied with coal from "Szczerców" Field, will be accompanied by trace elements transfer. On the basis of the conducted investigations it has been found that the biosphere is most threatened by mercury emissions. As shown by the presented results of analyses and calculations, the emissions of mercury in "Bełchatów" Power Plant are low. Mercury is accumulated chiefly in gypsum produced in the FGD plant. The content of mercury in slag and ash is low.

Opis:

Background. The work is designed to uncover the pattern of mutual relation among trace elements and epidemiological data in the degenerated intervertebral disk tissue in humans. Hitherto the reason of the degenerative process is not fully understood. Trace elements are the basic components of the biological compound related both its metabolism as well as environmental exposure. The relation pattern among elements occurs gives new perspective in solving the cause of the disease. Methods. We have analysed trace elements content in the 30 intervertebral disc from 22 patients with degenerative disc disease. The concentrations of Al, Cu, Cd, Mo, Ni and Pb were determined with Atomic Absorption Spectrometry. To analyse the multidimentional relation between trace element concentration and epidemiological data the chemometric analysis was applied. Results. The similarity have been shown in occurrence of following pairs: Cd-Mo as well as Mg-Zn. The second pair was correlated with Pb concentration. Pb levels are observed to be competitive to Cu concentration. Cd concentration was related to Zn and Mg deficiency. No single but rather cluster of epidemiological data show observable influence on the TE tissue variance. Zn and Cu was related to the male sex. Operation with orthopedic implants were related to combined Al, Mo and Zn concentration. Conclusions. This is the first chemometric analysis of trace elements in disk tissue. It shows multidimentional relations that are missed by the classical statistic. The analysis shows significant relation. The nature of the relations is the basis for further metabolic and environmental research.

The experimental factors included two soil tillage systems and seven weed control methods in potato. Iron, copper and zinc in weeds were deter- mined with the AAS method. The trace element content in weed dry matter before row closure of potato depended significantly on soil tillage methods (excluding Cu), weed control methods and weather conditions, and, prior to tuber harvest, on soil tillage and weather conditions during the growing season. The uptake of Fe, Cu, and Zn by weeds from the area of 1 hectare depended on the experimental factors, weed biomass and weed chemical composition.

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 aim of this study was to assess the spatial distributions of total trace elements content in the bottom sediments of Dzierżno Duże water reservoir, along with the comparison of the accuracy and characteristics of Kriging and IDW interpolations. On the basis of regular measurement grid consisting of 53 points, bottom sediments samples were collected. Mean values of total trace elements content in bottom sediments of Dzierżno Duże were as follows: Zn – 410 mg/kg, Pb – 57 mg/kg, Cr – 36 mg/kg, Cu – 40 mg/kg, Cd – 5 mg/kg, Ni – 16 mg/kg and Ba – 267 mg/kg. According to the geochemical quality classification, the concentrations of Cd in 32% of samples were assigned to class IV (heavily contaminated), 45% to class III (contaminated), Zn in 42% samples to class III with 1 sample in class IV and 26% to class II (slightly contaminated), Pb in 9% to class III and 58% to class II, Cu in 4% to class III and 68% to class II, Cr in 17% to class II, Ni in 55% to class II, Ba in 8% to class III and 61% in class II. Coefficient of determination was determined between each case of trace elements content. The highest correlation (R2 in range from 0.81 to 0.96) was observed between Zn and Pb, Zn and Cu, Zn and Cr, Zn and Ni, Pb and Cu, Pb and Cr, Cu and Cr, Cr and Ni. Significant correlation (R2 in range from 0.70 to 0.80) occurred between: Zn and Cd, Pb and Ni, Cu and Ni, Cd and Ni. The lowest correlations (R2 in range from 0.25 to 0.70) were observed between concentration of Ba and the rest of trace elements. Two different interpolation methods were chosen for the purpose of generating spatial distributions – Inverse Distance Weighted and Ordinary Kriging. These methods were chosen for purpose of obtaining optimal accuracy result of spatial distributions. The distributions of trace elements content were classified by means of geochemical criteria. In the case of accuracy comparison between IDW and Ordinary Kriging, the former had slightly better results in terms of mean value and root mean square. The generated spatial distributions allowed to determine the most contaminated areas, which were mainly northern-central and southern-central parts of water Dzierżno Duże reservoir.

Opis:

Objectives: The method for the determination of As, Al, Cd, Ni, Pb (toxic elements) and Cr, Co, Cu, Fe, Mn, Zn (essential elements) in human urine by the use of Inductively Coupled Plasma Mass Spectrometry (quadrupole ICP-MS DRCe Elan, Perkin Elmer) with the dynamic reaction cell (DRC) was developed. Materials and Methods: The method has been applied for multi-element analysis of the urine of 16 non-exposed healthy volunteers and 27 workers employed in a copper smelter. The analysis was conducted after initial 10-fold dilution of the urine samples with 0,1% nitric acid. Rhodium was used as an internal standard. The method validation parameters such as detection limit, sensitivity, precision were described for all elements. Accuracy of the method was checked by the regular use of certified reference materials ClinCheck®-Control Urine (Recipe) as well as by participation of the laboratory in the German External Quality Assessment Scheme (G-EQUAS). Results: The detection limits (DL 3s) of the applied method were 0.025, 0.007, 0.002, 0.004, 0.004, 0.086, 0.037, 0.009, 0.016, 0.008, 0.064 (μg/l) for Al, As, Cd, Cr, Co, Cu, Fe, Mn, Ni, Pb, Zn in urine, respectively. For each element linearity with correlation coefficient of at least 0.999 was determined. Spectral interferences from some of the ions were removed using DRC-e with addition of alternative gas: methane for cobalt, copper, cadmium, chromium, iron, manganese, nickel and rhodium, and oxygen for arsenic. Conclusions: The developed method allows to determine simultaneously eleven elements in the urine with low detection limits, high sensitivity and good accuracy. Moreover, the method is appropriate for the assessment of both environmental and occupational exposure.

Opis:

Research concerning the effect of the application of waste sulfur pulp (doses: 10, 20, 30, 60 mg S • kg–1 d.m. of soil) on selected soil properties was carried out. The pulp contained sulfur in the elemental form. Before setting up the experiment, the soil had a slightly acid reaction (determination in 1 mol • dm–3 KCl) and was not contaminated with heavy metals. After conducting the incubation experiment, it was observed that the application of sulfur pulp led to a statistically significant (and proportional to the dose) increase in the content of available sulfur in soil. Application of waste caused a decrease in soil pH and an increase in the mobility and availability of Zn, Cd and Mn (extracted with 0.01 mol • dm–3 CaCl2). In relation to soil without waste, more Zn, Cd and Mn (by 4–51%, 9–24% and 0.1–31%, respectively) was determined. Liming reduced the acidifying effect of the introduced waste – after 150 days, only soil with the highest dose of sulfur pulp was characterized by a statistically significantly lower pH than the soil without the waste addition. An increase in the rate of sulfur oxidation was also observed – after 150 days of the experiment, more sulfate sulfur (by 14.4–34.5%) was determined, with respect to treatments of the unlimed series. A considerably lower content of Zn, Cd and Mn was determined in the limed soil than in the unlimed one. Regardless of waste dose and date of analysis, the soil contained a trace content of mobile forms of Cu, Cr, Ni and Pb.

Opis:

The procedure of restorative proctocolectomy is associated with a complete removal of the colon and slight reduction of ileum length, which together can lead to systemic shortages of trace elements. Inflammatory changes in the pouch mucosa may also have some impact. However, there is no data on trace elements in pouchitis. Therefore, in the present study we aimed to assess the effect of acute pouchitis on the status of selected trace elements in rats. Restorative proctocolectomy with the construction of intestinal J-pouch was performed in twenty-four Wistar rats. Three weeks after the surgery, pouchitis was induced. Eight untreated rats created the control group. Liver concentrations of selected micronutrients (Zn, Cu, Co, Mn, Se) were measured in both groups six weeks later, using inductively coupled plasma mass spectrometry. Liver concentrations of trace elements did not differ between the study and the control groups. However, copper, cobalt and selenium concentrations [μg/g] were statistically lower (p<0.02, p<0.05 and p<0.04, respectively) in rats with severe pouchitis (n=9) as compared with rats with mild pouchitis (n=7) [median (range): Cu - 7.05 (3.02-14.57) vs 10.47 (5.16-14.97); Co - 0.55 (0.37-0.96) vs 0.61 (0.52-0.86); Se - 1.17 (0.69-1.54) vs 1.18 (0.29-1.91)]. In conclusion, it seems that acute pouchitis can lead to a significant deficiency of trace elements.

Opis:

The pollution of surface water and sediments by heavy metals has become a difficult thing to deal with due to their toxicity and accumulative behavior. The present study was undertaken to provide information on the concentrations and distribution of selected heavy metals in surface water and sediments from Warri River, and to compute a contamination/pollution index of heavy metals. Surface water and sediment samples were collected using standard methods and then analysed for nine trace metals. These metals were determined using a Flame Atomic Absorption Spectrophotometer – UNICAM 929. According to our results, the mean concentrations of the select metals in the sediments were higher than those of the surface water. The figures, however, varied significantly in the six sample locations (SW1–SW6). In the sediments, the highest mean concentration was of Fe (504.13 mg/kg) in location SW1, whereas in surface water, generally, the highest mean concentration was of Fe (1.23 mg/l). In other words, mean metal levels in the sediments exceeded those of surface water. This indicates that sediments are a sink for metal pollution loads. Computation of contamination/ pollution index in sediment matrix revealed that Cd moderately polluted the sediment, Zn, Fe, Ni slightly, yet significantly contaminated the sediment, while Cu, Cr and Mn very slightly contaminated the sediments. The mean values of metals in this present study were compared with other values reported by other researchers. The higher than normal metal values were attributed to anthropogenic wastes, runoff, refinery jetty and varied petroleum related activities in the area.

Opis:

The aim of this study was to determine the effect of neutralizing substances on the content of trace elements in maize on soil contaminated by heating oil. For the treatments without neutralizing substances, the dependency between increasing doses of heating oil and the cadmium content of plants was direct, yet the range of changes was relatively small. Under the influence of increasing doses of heating oil, the cadmium and manganese contents increased up to a dose of 10 g of oil per kg of soil, lead up to 15 g of oil per kg of soil and chromium within the full range of its doses, as compared to the control treatment (without heating oil). Higher doses of heating oil resulted in a decrease in cadmium, lead and manganese contents in maize. All of the tested substances had a significant effect on the content of trace elements in maize. Calcium oxide, zeolite and bentonite had a more pronounced effect than compost and nitrogen on the content of trace elements in this plant. A favourable effect, restricting the content of most of them in the maize was only observed for cadmium and manganese, in contrast to lead and chromium.

Opis:

Although beneficial properties of mineral waters are acknowledged by law in many countries, the use of water for medicinal purposes is not universally accepted. Notably numerous waters (especially mineral and curative ones) have high concentrations of mineral and trace elements. These mineral waters are common on the market and their availability is not regulated by law. Due to the hazard of overdosing, quantification of trace elements and minerals seems to be necessary. The World Health Organization, European Standards and Polish Standards recommend different methods for elemental determination, i.e. spectrometry, photometry for zinc determination, colorimetry or spectrometry for copper, and ionic chromatography for calcium, chloride and fluoride. In this paper, alternative, electrochemical methods have been applied to determine zinc, copper, calcium, chloride and fluoride in most popular natural and curative waters from southern Poland. The determined elemental content varied between 3.85-33.54 μg L-1 for zinc, 85-15.33 μg L-1 for copper, 2.8-2433.63 mg L-1 for chloride, 0.4-1.66 mg L-1 for fluoride and 11.05-478.48 mg L-1 for calcium. The voltammetric method was tested according to the validation procedures, taking into account the following parametes: linearity range, limit of detection and limit of quantification and precision. The results show that the applied electroanalytical methods are suitable for determination of the selected elements in waters of natural origin, ensuring low instrumental and analysis costs while providing results comparable with ones achieved with recommended methods.

Opis:

Szybko rosnące wierzby krzewiaste, jako rośliny pionierskie, stosuje się do zagospodarowania terenów zdegradowanych. Fitoremadiacyjne właściwości wierzb są również od wielu lat wykorzystywane w roślinnych oczyszczalniach ścieków. Nowym zastosowaniem wierzby wiciowej jest jej wykorzystanie jako surowca energetycznego. Biomasę można spalać w formie zrębków, brykietów i pelet. Przyspieszenie przyrostu biomasy, zwiększenie odporności na czynniki stresowe oraz możliwość regulacji pobierania pierwiastków śladowych mogłyby podnieść przydatność wierzb w inżynierii środowiska. Prowadzone badania wykazały wiele możliwości zastosowania biotechnologii laserowej w inżynierii środowiska. Interdyscyplinarne doświadczenia potwierdziły, że efektem stosowania naświetlania nasion i sadzonek roślin światłem laserów małych mocy może być przyspieszenie ich wzrostu, zwiększenie odporności na zanieczyszczenia czy zmiana stopnia kumulacji w tkankach niektórych metali, jak np. ołów i kadm. Właściwości te mają znaczenie przy biologicznej rekultywacji skażonych gruntów. Przedstawiony eksperyment miał na celu sprawdzenie różnic w kumulacji pierwiastków śladowych w liściach wierzb wiciowych, których zrzezy przed posadzeniem zostały poddane działaniu monochromatycznego, spójnego światła emitowanego przez lasery małych mocy. Stymulacja światłem miała charakter przerywany, a algorytmy fotostymulacji zostały dobrane na podstawie wcześniejszych doświadczeń. Otrzymane wyniki potwierdziły, że przy zastosowaniu stymulacji laserowej o właściwie dobranych parametrach, można zmienić stężenie pierwiastków śladowych w biomasie liści.
The fast growing willows are pioneer plants and are often used in land reclamation process. Phytoremediation capabilities of willows have been utilized for many years in the sewage treatment and water purification in hydrobotanical wastewater treatment plants. However, the use of willow as an energy source is a new application. Dry biomass may be burned in the form of chips, briquettes and pellets. The acceleration of the biomass growth, increased resistance to stress factors and the ability to regulate the absorption of trace elements could improve the usefulness of willow in environmental engineering. Laser light applications for biotechnology have been reported in a number of previous research studies in environmental engineering. Interdisciplinary research studies on the application of low intensity laser stimulation of plants seeds and seedlings proved, that effects of photostimulation may increase biomass production and plants resistance to environmental pollutions and unfavorable environmental factors as well as change of trace elements concentration in their tissues eg Pb, Cd. These properties are important for biological reclamation of contaminated industrial lands. The purpose of presented experiment was to validate the possibility of applying photostimulation for changing the accumulation of trace elements in biomass of willow leaves. Willow cuttings, before being planted, were subjected to monochromatic, coherent light emitted by low power lasers. The light stimulation was intermittent, photostimulation algorithms have been selected on the basis of previous experience. The results confirmed that the application of laser stimulation, with the well-chosen parameters, can change the concentration of trace elements in the leaf biomass.

Objectives: To describe blood lead (Pb-B), cadmium (Cd-B) and mercury (Hg-B) levels in children living in urban, industrial and rural areas in Fez city (north of Morocco) and to identify the determinants and some renal effects of exposure. Material and Methods: The study was conducted from June 2007 to January 2008 in 209 school children (113 girls, 96 boys), aged 6-12 years, from urban, industrial and rural areas in Fez city. Interview and questionnaires data were obtained. Blood and urinary samples were analyzed. Results: The mean of blood lead levels (Pb-B) in our population was 55.53 μg/l (range: 7.5-231.1 μg/l). Children from the urban area had higher blood lead levels (BLLs) mean (82.36 μg/l) than children from industrial and rural areas (48.23 and 35.99 μg/l, respectively); with no significant difference between boys and girls. BLLs were associated with traffic intensity, passive smoking and infancy in the urban area. The mean of blood cadmium levels (BCLs) was 0.22 μg/l (range: 0.06-0.68 μg/l), with no difference between various areas. Rural boys had higher BCLs mean than rural girls, but no gender influence was noticed in the other areas. BCLs were associated with the number of cigarettes smoked at children's homes. The blood mercury levels (BMLs) mean was 0.49 μg/l (range: 0.01-5.31 μg/l). The BMLs mean was higher in urban and industrial areas than in the rural area with no gender-related difference. BMLs were associated with amalgam fillings and infancy in the urban area. About 8% of the children had BLLs ≥ 100 μg/l particularly in the urban area, microalbuminuria and a decrease in height were noticed in girls from the inner city of Fez and that can be related to high BLLs (89.45 μg/l). Conclusions: There is a need to control and regulate potential sources of contamination by these trace elements in children; particularly for lead.

The aim of this work was to assess the contamination of the landslide lakes located within Babiogórski National Park. For this purpose, samples of water and bottom sediment from 12 lakes were collected. Chemical analyses of the waters (including main cation and anion concentrations, trace-metal levels and selected physicochemical parameters) and of the sediments (including heavy metals) were performed. The waters are acidic to neutral and are characterized by low mineralization. Concentrations of trace elements are commonly low. Elevated levels of Fe, Mn and Al are probably related to natural geochemical processes. The sediments are strongly contaminated by Cd, whereas other trace metals levels are at their hydrogeochemical background. The high level of Cd contamination is most probably related to long-range industrial emissions.

Opis:

Seboah Hill - a small body of peralkaline granite (< 0.1 km2) in south-western Egypt containing aegirine minerals ± magnesiohornblende ± riebeckite, cut by dikes of riebeckite-aegirine rhyolite, and exhibiting high radioactivity in veins of K-feldspar-aegirine-chalcedony-quartz ± trace hematite ± trace goethite was sampled and analyzed using inductively coupled plasma methods. Whole-rock chemical compositions of 5 granite, 3-rhyolitedike and 10 radioactive vein samples are presented. Of special significance is the enrichment of trace elements and rare earth elements (REE) in the radioactive veins. These include up to 6081 ppm Zr, 4252 ppm Ce, 1514 ppm Nd, 1433 ppm La, 1233 ppm Nb, 875 ppm Y, 388 ppm Pr, 350 ppm Th, 222 ppm Sm, 189 ppm Gd, 159 ppm Dy, 153 ppm Hf, 83 ppm Er, 76 ppm Yb and 58 ppm U. The chondrite-normalized patterns of REE in all samples show only limited variation and have negative europium (Eu) anomalies. These findings suggest that the sources of the REE are genetically related. Values of the Eu anomalies vary from 0.38-0.41 for the radioactive veins, 0.39-0.53 for the granite and 0.31-0.44 for the rhyolite dikes. Eu variations are consistent for different paragentic stages.

Opis:

Mires are common in the landscape of the Kraków-Częstochowa Upland, but they are rarely explored by Earth scientists. In addition to numerous morphological depressions filled with biogenic sediments, mires also occur within river valley, usually upstream from gaps. The intensification of marsh formation within the Białka River valley (left-side tributary of Krztynia, upper Pilica catchment) may have been influenced by the occurrence of poorly permeable, fluvial silty sands in the bedrock. Infilling of the studied depression at Młyny was accomplished via fluvial sedimentation characterised by local aggradation interrupted by carbonate precipitation, and sedentation of autochthonous organic matter. The former sediment type is represented mostly by mineral-organic aggraded silt with a dominant fine fraction, occurring mostly in the basal part of the studied core, and sand fraction in the top interval of the core, superjacent to calcareous-clay gyttja. Ash content reaches up to 87% and Fe concentrations are periodically elevated (30–48 mg/g). Calcium carbonate (CaCO3) also occurs in the studied oxbow mire deposit, exceeding 40% in some intervals, which indicates that a more important part was played by groundwaters in the water balance of the Białka valley. This periods were periodically interrupted due to higher flooding activity and recorded by mineral sediments characterised by specific granulometric composition, and an elevated percentage of organic matter deposited as rhythmists. Elevated concentrations of trace elements noted in a horizon dated at 1885±105 BP by means of radiocarbon dating may point to human impact on the environment due to the adaptation of economy to local conditions. The geochemical record of human activity is corroborated by archaeological data from various parts of the Białka valley catchment. The reason for the concentration of trace elements being highest in the top interval of the studied core is the intense economic development of Silesia-Kraków region, and the associated deforestation, mining and metallurgy.

Opis:

W pracy przedstawiono wyniki badań popiołów lotnych otrzymywanych ze spalania węgla kamiennego (Próbka 1) i brunatnego (Próbka 2) w aspekcie pozyskiwania z nich pierwiastków ziem rzadkich (REE). Na wybranych próbkach przeprowadzono analizy XRD i SEM-EDS celem określenia ich składu mineralnego oraz chemiczne, które pozwoliły określić ilość pierwiastków głównych, śladowych oraz pierwiastków ziem rzadkich. Badane popioły w składzie mineralnym posiadają głównie szkliwo glinokrzemianowe, kwarc oraz w przypadku Próbki 1: mullit, magnetyt i hematyt, natomiast w Próbce 2 stwierdzono: wapno, kalcyt, anhydryt, pla- gioklazy. Analizując ilość pierwiastków ziem rzadkich oba badane popioły zawierają w sobie stosunkowo wysokie ich ilości (rzędu 450 ppm).Większe zawartości REE posiada popiół z węgla brunatnego. Spośród badanych pierwiastków ziem rzadkich największe ilości zanotowano dla ceru (110 ppm – Próbka 1, 142 ppm Próbka 2), lantanu (55 ppm – Próbka 1, 76 ppm – Próbka 2), neodymu (49 ppm – Próbka 1, 69 ppm – Próbka 2) i itru (47 ppm Próbka 1, 63 ppm – Próbka 2). Zawartości pierwiastków ziem rzadkich w badanych popiołach lotnych są zbliżone do wyników uzyskanych przez innych autorów dla tego typu popiołów, dlatego też mogą one stanowić potencjalne źródło pozyskiwania z nich REE.
This paper presents the results of efforts to acquire rare earth elements from fly ash derived from burning bituminous (Sample 1) and lignite (Sample 2) coals. On selected samples, analysis of XRD and SEM-EDS was carried out to determine their mineral composition, while chemical analyses made it possible to determine the composition of major trace elements and rare earth elements. Test ashes are composedmainly of aluminosilicate, quartz, and in the case of Sample 1, mullite, magnetite, and hematite. Sample 2 also contained lime, calcite, anhydrite, and plagioclase. Both tested ashes contained relatively high quantities of rare earths (about 450 ppm). Greater content was recorded for the ash from lignite. Among the studied rare earth elements, the largest quantities were recorded for cerium (110 ppm Sample 1, 142 ppm – Sample 2), lanthanum (55 ppm Sample 1, 76 ppm Sample 2), neodymium (49 ppm Sample 1, 69 ppm Sample 2), and yttrium (47 ppm – Sample 1, 63 ppm Sample 2). The content of rare earth elements in the studied fly ashes are similar to the results obtained by other authors for this type of ash; they may therefore be a potential source for REE acquisition.

Opis:

The sewage sludge originating from wastewater treatment plants (WWTP) serving rural areas is suggested for agricultural or natural usage. However, sewage sludge is beforehand subjected to the several pre-treatments, which involve stabilization, hygienisation and pre-composting. These methods mainly decrease the amount of organic substances and the presence of microorganisms, but hardly affect the concentrations of heavy metals. The advantages of using sludges as fertilizer for improving and sustaining soil fertility and crop production are numerous. The addition of sewage sludge to soils could affect the potential availability of heavy metals. Trace elements are distributed in the soil in various forms: solid phases, free ions in soil solution, soluble organic-mineral complexes, or adsorbed on colloidal particles. The most undesirable heavy metals in sewage sludge that are toxic for the living organisms include: cadmium, chromium, nickel, lead and mercury. In the study, the concentrations of trace elements (Pb, Cd, Cr, Hg, Ni, Zn, Al, As, Se, B, Ba, Br, Ca, Cu, Fe, Mn, Na, Ga, Li, Mo, Sr, Mg, K, Ru, Tl, V, U) were tested in the sewage sludge obtained from a WWTP serving rural areas (PE< 9 000). In each case, the tested sewage sludge was meeting the criteria of stabilization and was used for agriculture and land reclamation purpose. All the samples were collected in 2016 and subjected to microwave mineralization in a closed system in aqua regia. The total amounts of macro and microelements were determined with a spectrophotometer Coupled Plasma emission ICP-OES. It was found that the total concentrations of trace metals in all of sewage sludges are the same as the Polish regulation limit of pollutants for sludge to be used in agriculture. European legislation is less restrictive and permits higher contents of heavy metals in sludge used for agriculture than Asia. The trace elements (cadmium: 1.16 mg·kg^-1/d.m. in thePolish sewage sludge, are much higher than those in the other countries. Copper and zinc were the most prevalent elements observed (111.28 mg·kg^-1/d.m. and 282.94 mg·kg^-1/d.m., respectively). The concentrations of copper in the Polish sewage sludge are much lower (49–130 mg·kg^-1/d.m.) than european sewage sludge (522–562 mg·kg^-1/d.m.). The two of the tested heavy metals (beryllium, bismuth) were under the detection limit, while gallium, molybdenum, thallium, vanadium and silver were detected in the concentrations lower than 0.005 mg·kg^-1/d.m. According to the obtained results, in all the tested samples, the total amount of trace elements, did not exceed the limit values in sewage sludge for their use in agriculture and land reclamation.

Opis:

Aplikowanie inhibitorów nitryfikacji wraz z nawozami azotowymi (zawierającymi zredukowane formy azotu: amonową i amidową) może wzmacniać zakwaszające działanie tych nawozów na glebę. W efekcie może to prowadzić do obniżenia pH oraz zmian zawartości dostępnych dla roślin form metali ciężkich i pierwiastków śladowych w glebie. Celem badań była ocena wpływu stosowania nawozów azotowych z ENTEC-26 (zawierającego inhibitor nitryfikacji 3,4-dimetylopyrazolofosfat /DMPP/) i saletrą amonową na skład mineralny korzeni spichrzowych marchwi. Przeprowadzono dwuletnie badania z polową uprawą marchwi Kazan Fj. Doświadczenie założono metodą split-plot w czterech powtórzeniach. Obiektami badań były kombinacje ze zróżnicowanym nawożeniem azotem: 1 - kontrola (bez nawożenia azotem), 2 - ENTEC-26 35+35, 3 - ENTEC-26 70+70, 4 - ENTEC-26 105+105, 5 - saletra amonowa 35+35, 6 - saletra amonowa 70+70, 7 - saletra amonowa 105+105, gdzie: 35+35, 70+70 i 105+105 oznacza dawkę azotu w kg N ha- 1 stosowaną w nawożeniu przedsiewnym i w nawożeniu pogłównym. w korzeniach spichrzowych oraz w glebie po uprawie marchwi zawartość: Ag, Al, B, Ba, Ca, Ce, Co, Cr, Dy, Fe, Ga, In, K, La, Li, Lu, Mg, Mn, Na, Ni, P, Pb, S, Sc, Sn, Sr, Ti, Tm, Y, Yb i V była oznaczana techniką ICP-OES. Nawożenie azotem miało istotny wpiyw na zawartość Co, Fe, In, Li, Mn, Ni, S, Sc, Sr, Y, Yb i V w marchwi. Jednakże wpiyw ten był zróżnicowany w zależności od zastosowanego sposobu nawożenia azotem w badanych kombinacjach. Nie stwierdzono natomiast istotnego oddziaływania nawożenia azotem na zawartość Ag, Al, B, Ba, Ca, Ce, Cr, Dy, Ga, K, La, Lu, Mg, Na, P, Pb, Ti i Sn w marchwi. W porównaniu z kontrolą, zastosowane nawożenie azotem we wszystkich dawkach zarówno w formie ENTEC-26, jak i saletry amonowej powodowało zmniejszenie zawartości Mg, Al, B, Ba, Ce, Fe, Ga, La, Ni, Pb, Ti, Y, V, Cr, Dy, In, Li, Lu, Sc i Yb oraz zwiększenie zawartości Ca, Sr i Ag w glebie po uprawie marchwi. Jednakże wykazane zmiany zawartości tych pierwiastków w glebie pod wpływem nawożenia azotem nie miały odzwierciedlenia w ich zawartości w korzeniach spichrzowych marchwi.

Opis:

Zbadano zróżnicowanie zawartości wybranych pierwiastków szkodliwych (Ba, Cd, Co, Cr, Cu, Ni, Pb, Zn, Mn, Be, Li, V, As, Ga) w próbkach litotypów i ich popiołach pochodzących z pokładu 405 (warstwy załęskie). Wykazano znaczną zmienność zawartości pierwiastków w badanych próbkach, zależną od rodzaju litotypu, a przede wszystkim od zawartości popiołu. We wszystkich litotypach najwyższe zawartości wykazały pierwiastki Ba i Mn. Pozostałe oznaczone pierwiastki ze względu na średni udział w litotypach można uszeregować w następującejkolejności: Zn < Pb < V < Cu < Ni < Cr < Ga < Co < Be < Li < As < Cd. Podobną tendencję udziału pierwiastków obserwowano w popiołach litotypów. Wyliczono współczynnik wzbogacenia (W) w popiołach litotypów, jako stosunek zawartości pierwiastka w popiele do zawartości w litotypie. Założono, że wartości współczynnika W są tym wyższe im wyższa jest zawartość pierwiastka związana z substancją organiczną węgla. Na zawartość pierwiastków śladowych w litotypach duży wpływ ma ich powinowactwo geochemiczne do substancji organicznej bądź mineralnej węgla, które określono na podstawie wielkości współczynnika wzbogacenia popiołów litotypów w te pierwiastki. Najwyższymi wartościami tych współczynników (od 5 do 7) charakteryzują się pierwiastki, takie jak Cr, Be, Cd i Cu, natomiast pozostałe pierwiastki wykazują niższe wartości (od ok. 2 do ok. 3). Najniższe wartości współczynnika wzbogacenia najczęściej obserwowano w przypadku: Co, Li i Mn. Na podstawie wyliczonych wartości współczynników wzbogacenia w popiele stwierdzono, że pierwiastki, takie jak Ba, Mn, Li, As, Co, Ga, Ni, Pb i Zn charakteryzowały się dużym powinowactwem do substancji mineralnej (niski współczynnik wzbogacenia w popiele). Maksymalna ich koncentracja przypadała na litotypy silnie mineralizowane – węgiel matowy bądź półbłyszczący. Natomiast nieliczne pierwiastki, jak: Cr, Be, Cd i Cu wykazały duże powinowactwo do substancji organicznej węgla (wysoki współczynnik wzbogacenia w popiele) i tendencję do maksymalnej koncentracji w litotypie błyszczącym. Na podstawie wykazanych istotnych korelacji pierwiastków śladowych w litotypach z zawartością popiołu można uznać, że pierwiastki te są głównie obecne w substancji mineralnej węgla.
This study analyzed the variability in the content of selected hazardous trace elements (Ba, Cd, Co, Cr, Cu, Ni, Pb, Zn, Mn, Be, Li, V, As, Ga) from the 405 (Załęże beds) coal seams’ coal lithotypes and their ashes. The significant variability in the content of the trace elements from the examined samples depends partly on the type of lithotype, and mainly on the ash content. Within all distinguished lithotypes, the highest concentrations were of the elements Ba and Mn. Other evaluated elements could be categorized by average content in the lithotypes in following order: Zn < Pb < V < Cu < Ni < Cr < Ga < Co < Be < Li < As < Cd. A similar trend in elemental content has been observed in the ashes from the lithotypes. The enrichment coefficient (W) values have been calculated for the ashes of the lithotypes as a ratio of an element’s content in the ash to its content in the lithotype. The assumption was that coefficient W values increase with increasing content of an element related to the organic matter of the coal. The highest values of these coefficients (from 5 to 7) were shown by Cr, Be, Cd, and Cu. The other elements exhibited lower values (from about 2 to about 3), and the lowest values of the enrichment coefficient were most frequently observed in the case of Co, Li, and Mn. On the basis of the calculated enrichment coefficient values in the ashes, it has been found that elements such as Ba, Mn, Li, As, Co, Ga, Ni, Pb, and Zn demonstrated high correlation with to the mineral substance (low enrichment coefficient in the ash). Their maximum concentrations decreased for the strongly mineralised lithotypes – dull coal or semi-vitreous coal. However, a small number of elements such as Cr, Be, Cd, and Cu demonstrated high correlation with the organic matter of coal (high enrichment coefficient in the ash) and tended to be most heavily concentrated in vitreous lithotype. The trace elements’ content in the lithotypes is connected with their affinity toward organic matter or mineral matter. This was determined based on the value of the coefficient of enrichment in the ashes of these elements. On the basis of the volume of the coefficient of correlation, a significant correlation was established between trace elements in lithotypes and content of ash and mineral matter in coal.

Opis:

Geochemical studies on the waters of four springs, including the Massabielle (MS) Spring, were carried out at Lourdes (France) following a long, rainless and warm period, with the aim of at least documenting the groundwater chemistry that was affected by the current meteoric input. The existence of anecdotal reports about anomalously elevated concentrations of trace constituents in the water of the MS Spring in the absence of any detailed studies inspired these first geochemical investigations of trace elements in the spring waters at Lourdes. The main common features of waters from the four springs studied in Lourdes are low total dissolved solids (255–318 mg/L), a slightly alkaline pH (7.50–7.68), oxidizing conditions (E_H = 458–472 mV), similar temperatures (11.3–13.1 °C), and their Ca-HCO₃ hydrochemical type, all of which are typical characteristics for an active zone within a hydrogeological system that is developed in carbonate-dominated bedrock. The spring waters, which represent an active turnover zone in the hydrogeological system, are only in partial chemical equilibrium with the minerals of the aquifer rocks. The enrichment of the MS Spring water with numerous elements (Li, Na, Cs, Ba, S, F, Br, REE, B, Sb and Bi), when compared with other springs studied and with the bedrock geochemistry, probably is caused by contributions from fluids (originating from the Pyrenees basement and/or from Triassic saliferous deposits) in the formation of the hydrogeochemical content of the zone under investigation. The germanium concentration in all of the waters studied was significantly lower than the concentrations typically found in fresh groundwater in the active zone; accordingly, the hypothesis concerning an anomalously high concentration of this element in the MS Spring water was invalidated. The preliminary geochemical research presented is part of an interdisciplinary geochemical-biological-tensiometric study of the spring waters at Lourdes.

Opis:

Na terenie Bydgoszczy z rzeki Brdy pobrano próbki osadów z 22 stożków nasypowych, powstałych przy wylotach kanałów ściekowych, którymi odprowadzano ścieki do rzeki. Z każdego stożka pobrano jedną uśrednioną próbkę, którą uzyskano przez połączenie od 4 do 9 pełnej miąższości rdzeni pobranych w różnych miejscach stożka. W próbkach oznaczono zawartość As, Ba, Cr, Pb, Co, Cu, Ni, Sn i Zn metodą ICP-OES oraz Hg metodą AAS z zatężaniem na amalgamatorze. Maksymalne zawartości pierwiastków wynosiły: Ba – 233 mg/kg, Cd – 6,9 mg/kg, Cr – 255 mg/kg, Cu – 231 mg/kg, Hg – 2,72 mg/kg, Ni – 36 mg/kg, Pb – 301 mg/kg, Sn – 19 mg/kg i Zn – 507 mg/kg. Przekroczenie dopuszczalnych zawartości Hg, Pb, Cr, Cu według Rozporządzenia MŚ o osadach bagrowniczych (Rozporządzenie, 2002a) stwierdzono w 11 stożkach nasypowych. Oszacowano, że w stożkach nasypowych utworzonych przy wylotach kanałów ściekowych nagromadziło się około 8,6 tys. m3 osadów dennych, z których około 4,5 tys. m3 stanowiły osady niezanieczyszczone, które mogły być relokowane w obrębie akwenu wodnego, a około 4,1 tys. m3 stanowiły osady zanieczyszczone.
In the city of Bydgoszcz, sediment samples were taken from 22 embankment cones in the Brda River, formed near the outlets of sewers through which waste water was discharged into the river. One averaged sample, which was obtained by combining 4 to 9 full-thickness cores taken at different locations of the cone, was collected from each cone. The samples were analysed for As, Ba, Cr, Pb, Co, Cu, Ni, Sn and Zn contents by the ICP-OES method, and for Hg content using the AAS method with pre-concentration on a gold amalgamate trap. The maximum levels of individual elements were as follows: Hg – 2.72 mg/kg, Cd – 6.9 mg/kg Cr – 255 mg/kg, Sn – 19 mg/kg, Zn – 592 mg/kg, Cu – 231 mg/kg, Ni – 74 mg/kg, Pb – 301 mg/kg, and Ba – 233 mg/kg. The concentrations exceeding permissible limits of Hg, Pb, Cr, Cu, according to the Decree of the Minister of the Environment (Rozporządzenie, 2002) for dragged sediments, were found in 11 embankment cones. It was estimated that the embankment cones set up at the mouths of the sewers have accumulated about 8.6 thousand m3 of sediments, of which about 4.5 thousand m3 of sediments were uncontaminated and could be relocated within the body of water, and about 4.1 thousand m3 of sediments were contaminated.

The aim of the study was to determine the effect of bottom sediment on the pH and content of available forms of P, K, Mg and aluminium exchangeable in the soil and on the yield of oats.The research was carried out in the Podlasie voivodship on very light soil. The material for the tests were samples of bottom sediment. In the experiment a bottom sediment from the breeding pond and soil was used. In the sediment bottom sediment sam-ple, the following parameters were determined: pH, heavy metal content (lead, cadmium, zinc, copper), as well as the content of aluminum, phosphorus, potassium and magnesium. The reaction of the bottom sediment was also determined. In soil samples, the content of exchangeable aluminium, available forms of phospho-rus, potassium, magnesium was determined and the soil reaction was determined. The obtained results confirmed the influence of bottom sedi-ment on reducing the content of exchangeable aluminium in the soil. The analyzes show that the soil after application of bottom sediment contained significantly less exchangeable aluminium. The sludge also influenced the increase of soil pH and the incre-ase of magnesium content in the soil. There was no influence of the use of bottom sediment on the content of available phospho-rus and potassium in the soil and on oat yield.

Opis:

Badaniom poddano torfy z trzech torfowisk (torfowiska wysokiego Otalżyno oraz torfowisk niskich Huczwa i Stoczek). W próbkach torfu, po ich pełnym kwasowym roztworzeniu, określono zawartość pierwiastków śladowych (Li, Be, As, Se, Rb, Ag, Sb, Cs, Tl, Th, U, Ba, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sn, Sr, Ti, V i Zn) i głównych (Al, S, Ca, Fe, K, Mg, Mn, Na, P i TOC). Najniższą zawartością pierwiastków śladowych odznaczały się torfy z torfowiska Otalżyno, a najwyższą – torfy z torfowiska Stoczek. Zróżnicowanie stężenia pierwiastków jest ściśle związane ze składem chemicznym skał występujących na terenach przyległych. Zawartość pierwiastków śladowych wykazuje wysoką korelację z zawartością Al, Fe i S, niższą z P, jeszcze niższą z Ca, a najniższą z TOC.
Studies of peat from three peat bogs (Otalżyno bog, Huczwa and Stoczek fens) were conducted. In peat samples, after the total acid digestion, the content of trace (Li, Be, As, Se, Rb, Ag, Sb, Cs, Tl, Th, U, Ba, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sn, Sr, Ti, V and Zn) and major (Al, S, Ca, Fe, K, Mg, Mn, Na, P and TOC) elements were determined. The lowest contents of trace elements were found in the raised peat bog Otalżyno. The peat from the Stoczek fen shows the highest contents of trace elements. Differences in the content of elements in the peat are strictly dependent on the chemistry of the rocks occurring in the area surrounding the bog. Trace elements display a significant correlation with the content of Al, Fe and S, a weaker correlation with P, even slightly weaker with Ca, and the weakest with TOC.

Opis:

The chemical composition of the Cretaceous deposits of the Grajcarek thrust-sheets (Pieniny Klippen Belt, Poland) has been investigated to provide information on palaeoenvironment and provenance of pelagic and turbiditic particles. The material studied shows large variations in terrigenous and biogenic content. Phyllosilicates (mirrored in amounts of Al2O3, average 15 wt.%) and carbonates (6 wt.% of CaO) are common mineral components of the deposits excluding the Cenomanian radiolarian shales (CRS) that are enriched in silica "Immobile" elements may be accommodated by phyllosilicates and accessory minerals (i.e. zircon, xenotime, apatite and Ti-oxides). Heavy minerals are significant within the Szlachtowa Fm. High field strength elements (HFSE) in the Malinowa Fm. are housed in secondary apatite and Fe-oxides. Lithophile trace elements (LILE) concentrations in the material studied are lower/comparable to Post-Archean Australian Shale (PAAS). Ba concentration in the CRS probably reflects enhanced bioproductivity. Interaction between major oxides, distributions of "immobile' and lithophile elements suggest that variation in trace elements through the succession was mainly controlled by the terrigenous input. The material studied was sourced from intermediate to felsic rocks of the Czorsztyn (Oravic) Ridge. The Szlachtowa Fm. and CRS are more mature than others due to low contents of clay minerals. The Szlachtowa Fm. also contains recycled material. The CRS correspond to the oceanic anoxic event 2 (OAE 2) whereas the "Black Flysch" of the Szlachtowa and Opaleniec formations may be related to the Early Cretaceous OAE 1

Opis:

Do badań mających na celu określenie stopnia zanieczyszczenia osadów dennych Pb, Zn oraz Cr wytypowano jezioro Sunia położone na obszarze Pojezierza Olsztyńskiego, stanowiącego zachodnią część Pojezierza Mazurskiego. Jezioro Sunia położone jest na wysokości 116 m n.p.m., około 30 km na północ od Olsztyna w gminie Świątki. Badane jezioro posiada powierzchnię 111,6 ha, maksymalną głębokość 8,8 m. Akwen posiada jeden dopływ po stronie południowo-zachodniej, a wody z jeziora odpływają w północno-zachodniej części akwenu. Zbiornik składa się z akwenu głównego oraz zatoki oddzielonej wypłyceniem. Całkowity obszar zasilania jeziora wynosi 450 ha, z czego większość zajmują użytki rolne. Badania wykazały, że średnia zawartość materii organicznej w osadach jeziora Sunia wynosiła 24,8%, co jest charakterystyczne dla jezior polodowcowych. Najniższą jej zawartość (12,5%) obserwowano w osadach pobranych po wschodniej stronie zbiornika oraz w miejscu wypłycenia pomiędzy zatoką a głównym akwenem, największym (30,3%) w centralnej części zatoki. Znaczna zawartość materii organicznej w osadach jeziora Sunia jest skutkiem intensywnego dopływu substancji biogennych z jego zlewni, w której prowadzono intensywną gospodarkę rolną. Wartości średniej koncentracji pierwiastków śladowych w zbiorniku układają się w następujące szeregi: Cr < Pb < Zn, a ich wzajemne proporcje kształtują się na następującym poziomie: 8,1 < 22,9 < 45,2. Obserwuje się znacznie niższe koncentracje metali w strefach litoralowych niż w profundalu.
The study aimed to determine the degree of contamination of bottom sediments Pb, Zn, Cr were selected Sunia lake located in the Olsztyn Lake District constituting the western part of the Masurian Lake District. Sunia lake is situated at an altitude of 116 m above sea level, about 30 miles north of Olsztyn, in the municipality of Świątki. The test lake has a surface 111.6 ha, a maximum depth of 8.8 m lake has one tributary of the south-west, and the waters of the lake depart in the north-western part of the basin. Lake Sunia consists of the main basin and the Gulf of shallow water separated. Total supply area of the lake is 450 ha of which the majority is arable land. The average content of organic matter in the sediments of Lake Sunia was 24.8%, which is typical of glacial lakes. The lowest content (12.5%) was observed in sediments collected on the eastern side of the tank and at the shallow water between the bay and the main sea, and the highest (30.3%) in the central part of the bay. A significant content of organic matter in the sediments of Lake is a result of intensive inflow of nutrients from the catchment, which conducted intensive farming. The average concentration of trace elements in the container are arranged in the following series: Cr < Pb < Zn, and their relative proportions are at the following rates: 8.1 < 22.9 < 45.2. There is a much lower concentration of metal in the zones littoral than in profundal.

Opis:

In this study, wild edible mushroom collected from Rivers and Imo state Nigeria were evaluated for heavy metals and dietary intake risks assessment. Four species of edible mushrooms were collected each in Imo (Lentinus squarrosulus, Pleurotus ostreatus, Lenziles betulina and Grifola polypilus frondosa) and River state (Lentinus squarrosulus, Pleurotus tuber-regium, Lenziles betulina, Auricularia aurucula) and metals extracted using HNO3 before analysis using flame atomic absorption spectrometry (F-AAS) in Varian AA 240 FS apparatus. Results showed that all metals showed concentrations lower than the permissible limits of World Health Organization (WHO) and Food and Agricultural Organization (FAO) while Pb was not detected in all samples analyzed and Cd in samples collected from Rivers state. However, Cd was only detected (0.003 mg/kg) in one sample (Lenziles betulina) collected from Imo state. Fe exceeded recommended values in Lentinus squarrosulus, Pleurotus ostreatus and Lenziles betulina in Imo State. Bioaccumulation factors for all mushrooms were generally low (< 3). However, the potential tolerable weekly intake and target hazard quotient values for the four mushroom species were usually extremely low except for Fe (2.24) in Lenziles betulina. Consumption of mushrooms from these areas might pose no potential risk in terms of heavy metals except for Fe content in Lenziles betulina from Rivers state. However, in general, it can be concluded that the consumption of the studied mushroom species from all sites does not present any health risk arising from their regular consumption.

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.

Opis:

The concentrations of eight trace elements (As, Co, Cr, Cu, Fe, Mn, Pb and Zn) in the soil near a traffic way of Suzhou, Anhui province, China have been determined for the pollution assessment and source identification (along with quantification). The results indicate that Fe is the most abundant element followed by Mn, Zn, Cr, Pb, Cu, Co and As. These elements have low-medium coefficients of variation (0.059–0.293), indicating that some of them might have multisources. The combination of single pollution, geoaccumulation and the Nemerow composite indices suggest that the soils in this study are slightly polluted. Based on multivariate statistical analyses (including correlation, cluster and factor analyses), three sources responsible for the trace elemental concentrations in the soils have been identified, including geogenic, agricultural and traffic-related sources. Their mean contributions calculated based on the Unmix model are 35.9, 31.8 and 32.4%, respectively.

Opis:

Eight bacterial strains from areas contaminated with trace metals were selected for the experiments: Bacillus sp., Bacteroidetes bacterium, Flavobacterium sp., Luteibactor rhizovicina, Pseudomonas fluorescens, Pseudomonas sp., Serratia entomophila and Variovorax sp. Bacteria were transformed with pET21a expression plasmid encoding Brassica napus L. metallothionein 2 (BnMT2). Transformant colonies were examined for growth on solid culture medium containing trace metal ions (Cd and Pb). It was found that most of the analyzed bacterial strains were resistant to ampicillin, though the antibiotic inhibited their growth. It was demonstrated that growth of bacterial strains on a medium containing Pb ions was not inhibited, while Cd ion content limited or inhibited growth of some bacterial strains. No significant differences were noted in growth between transformed and untransformed bacteria of a given strain on the medium containing Pb ions. The BnMT2 transgene presence abolished adverse effects of Cd ions on Flavobacterium sp., Variovorax sp. and L.rhizovicina. Modified bacterial strains were demonstrated for potential use in treatment of soil contaminated with trace metals, especially Cd ions.
W przeprowadzonych badaniach wykorzystano osiem szczepów bakterii: Bacillus sp., Bacteroidetes bacterium, Flavobacterium sp., Luteibactor rhizovicina, Pseudomonas fluorescens, Pseudomonas sp., Serratia entomophila, Variovorax sp. wyizolowanych z terenów zanieczyszczonych jonami metali śladowych. Bakterie stransformowano plazmidem ekspresyjnym pET21a zawierającym fragment genu kodujący metalotioneinę typu 2 Brassica napus L. (BnMT2). Po uzyskaniu kolonii bakteryjnych (transformantów) sprawdzono ich wzrost na podłożu stałym zawierających jony metali śladowych (Cd i Pb). Stwierdzono, że większość analizowanych szczepów bakterii wykazuje oporność na ampicylinę, chociaż antybiotyk ogranicza ich wzrost. Wykazano, iż wzrost badanych szczepów na podłożu zawierającym jony ołowiu nie był hamowany, natomiast jony kadmu ograniczały lub hamowały wzrost niektórych szczepów bakterii. Nie stwierdzono znacznych różnic we wzroście pomiędzy bakteriami transformowanymi i nietransformowanymi danego szczepu na podłożu zawierającym jony ołowiu. Obecność transgenu BnMT2 niwelowała szkodliwe działanie jonów kadmu w przypadku Flavobacterium sp., Variovorax sp. i L. rhizovicina. Wykazano, że zmodyfikowane szczepy bakterii mogą znaleźć zastosowanie w procesie oczyszczania gleby zawierającej jony metali śladowych, a zwłaszcza kadmu.

Opis:

Different diagenetic environments have been recognized in the Early Miocene carbonate platform of Musayr Formation in the Red Sea rift area. Early marine diagenesis includes micritisation that occurs as thin envelope around skeletal and non-skeletal grains in low-energy mud dominated facies and isopachous fibrous calcite in high-energy grain-dominated facies. Pervasive meteoric water diagenesis resulted in cementation of the carbonates by coarse-crystalline blocky-drusy calcite and meniscus cements. Depletion of oxygen (avg. –9.08‰), carbon (avg. –1.6‰) isotopes and trace elements concentrations (avg. values of Fe: 1387 ppm; Mn: 1444 ppm; Sr: 419 ppm; Na: 1194 ppm) in conjunction with negative correlation between Mn2+ and oxygen isotope data suggest variable degrees of fluid-rock interactions and pervasive meteoric diagenesis. The formation of meteoric diagenesis in the Musayr Formation can be explained by two subsequent mechanisms: (1) the presence of meteoric lenses during the time of deposition might have been associated with active freshwater input from the hinterland (NE) due to fall in the relative sea level; (2) later uplift episode during Plio-Pleistocene may have also contributed to the pervasive meteoric diagenetic alterations of the carbonates of the Musayr Formation. The first mechanism is supported by the cement stratigraphy where the blocky-drusy cements postdate the meniscus cement. The latter mechanism seems to have more pronounced effect on the alteration of Musayr carbonate sequence by observing the occurence of late cements such as blocky calcite in most of the samples. The impact of meteoric diagenesis on the studied samples suggest that dissolution is less severe than cementation, hence the visible porosity is very low. Understanding the timing of meteoric diagenesis provides useful information about the reservoir quality distribution in syn-rift carbonate sequences.

Opis:

The aim of study was to assess the effect of bottom sediments on the concentration of macronutrients (K, P, Na, Mg, Ca) and trace elements (Zn, Cd, Pb, Cr, Ni, Cu) in the plant test. The experimental design comprised 6 treatments: soil (control), soil + 5% of sediment, soil +10% of sediment, soil + 30% of sediment, soil + 50% of sediment and sediment (100%) in relation to the soil dry mass. The test plant - maize was harvested after 70 days of vegetation. Bottom sediment added to soil had a positive effect on maize biomass in the lowest dose, i.e. 5%. Higher doses of the sediment caused a reduction in maize yield. Bottom sediment positively affected concentration of nutrients: N, Mg, Na, K, Ca, Zn, Ni, Cu of maize shoots. However, the shoot biomass did not meet for fodder with respect to quality. Applied bottom sediment, has high content of sandy fractions, acid reaction and low concentration of organic carbon, nitrogen, phosphorus and potassium, can not be used as a fertilizer. Using bottom sediment from Narożniki reservoir in plant cultivation, one should take into consideration a necessity of application of supplementary NPK fertilization due to low concentration of these elements both in the bottom sediment and maize yield.

The paper presents the content of selected elements in solutions formed after the synthesis of zeolitic material based on fly ash. Fly ash samples were taken from two pulverized fuel-fired boilers at the Rybnik Power Plant: one boiler fired solely with coal and one co-fired with coal and biomass. The tests conducted have shown that solutions remaining after zeolite synthesis from fly ash generated in boilers co-fired with coal and biomass had higher content of elements than those derived from fly ash generated from burning only coal. It was also found that increasing NaOH concentration of the solution used in zeolite synthesis caused increased content of the individual elements.
W artykule przedstawiono zawartości wybranych pierwiastków w powstałych roztworach po syntezie materiału zeolitowego na bazie popiołu lotnego. Próbki popiołu lotnego pochodziły z Elektrowni Rybnik z dwóch kotłów pyłowych: opalanego czystym węglem i ze współspalania węgla z biomasą. Przeprowadzone badania wykazały, że wyższe zawartości pierwiastków występują w roztworach poreakcyjnych, powstałych po syntezie popiołów pochodzących ze współspalania węgla z biomasą, niż w roztworach po syntezie popiołów będących produktem spalania czystego węgla. Stwierdzono ponadto, że wraz ze wzrostem stężenia NaOH roztworu zastosowanego do syntezy zeolitów wzrasta ilość poszczególnych pierwiastków.

Opis:

The research was conducted to determine the content of Cr, Cd, Ni and Pb in soil and plant biomass after application of newspaper waste. The pot experiment was conducted in the years 2010 and 2011 in the greenhouse and included the following objects: NP-0 soil without addition of newspaper, NP-1 the soil with addition of 1 % of newspaper and NP-3 the soil with addition of 3 % of newspaper. Addition of newspaper was calculated relative to the dry weight of the soil material. The study was conducted in pots containing 5.50 kg of air-dried soil material. Two plants were grown in the experiment: spring rape, ‘Felix’ c.v., in the first year and naked oats, ‘Siwek’ c.v., in the second. Rape was collected at the end of the flowering stage (73-day vegetation period), and oats at grain milk stage (75 days of vegetation). After preparation of plant material and soil, content of trace elements was determined by ICP-OES method on a Perkin Elmer Optima 7300DV apparatus. The results were converted to absolute dry weight of the material. Application of newspaper to soil did not increase (except for cadmium) the contents of lead, chromium or nickel in the aboveground parts of the plant. Studied trace elements were accumulated mainly in the plant roots. Roots contained on average from 51 to 82 % more of the test elements in relation to the aboveground parts. Higher amount of newspaper (3 %) added to the soil led to a higher accumulation of studied trace elements in the roots and lower in the plant aboveground parts. The addition of newspaper to the soil caused a reduction in acidity. Newspaper introduced to the soil generally did not increase the total content of trace elements.
Przeprowadzone badania miały na celu ocenę zawartości Cr, Cd, Ni i Pb w glebie oraz w biomasie roślin po aplikacji papieru gazetowego. Doświadczenie wazonowe prowadzono w latach 2010 i 2011 w hali wegetacyjnej. Doświadczenie obejmowało następujące obiekty: NP-0 – kontrola (gleba bez dodatku papieru gazetowego), NP-1 – gleba z 1 % dodatkiem papieru gazetowego oraz NP-3 – gleba z 3 % dodatkiem papieru gazetowego. Dodatek papieru gazetowego obliczono w stosunku do suchej masy materiału glebowego. Badania prowadzono w wazonach mieszczących 5,50 kg powietrznie suchego materiału glebowego. W doświadczeniu uprawiano dwie rośliny, w pierwszym roku rzepak jary odmiany ‘Feliks’, natomiast w drugim owies nagoziarnisty odmiany ‘Siwek’. Rzepak jary zbierano w końcu fazy kwitnienia (73 dni wegetacji), a owies w fazie dojrzałości mlecznej (75 dni wegetacji). Po odpowiednim przygotowaniu materiału roślinnego i glebowego, zawartość badanych pierwiastków śladowych oznaczono metodą ICP-ŚS na aparacie Perkin Elmer Optima 7300DV, a uzyskane wyniki przeliczono na absolutnie suchą masę materiału. Doglebowa aplikacja papieru gazetowego nie spowodowała zwiększenia zawartości (za wyjątkiem kadmu) ołowiu, chromu i niklu w częściach nadziemnych roślin. Badane pierwiastki śladowe były gromadzone głównie w korzeniach roślin. W stosunku do części nadziemnych roślin korzenie zawierały średnio od 51 % do 82 % więcej badanych pierwiastków. Większy dodatek papieru gazetowego (3 %) do gleby skutkował większą akumulacją badanych pierwiastków śladowych w korzeniach, a mniejszą w częściach nadziemnych roślin. Dodatek papieru gazetowego do gleby spowodował zmniejszenie zakwaszenia. Wprowadzenie do gleby papieru gazetowego na ogół nie wpłynęło na zwiększenie ogólnej zawartości badanych pierwiastków śladowych.

Opis:

Disturbances in levels of trace elements and oxidative stress are associated with the glycemic status, which is implicated in the development and progression of diabetes. The present study was conducted on 50 patients with type 2 diabetes, 40 years of age, gender and body mass index matched with healthy controls (Damanhur Educational Hospital, El Beheira, Egypt). Fasting blood glucose (FBG), serum catalase, paraoxonase activity, and malondialdehyde (MDA) levels were measured spectrophotometrically. The blood serum was digested and then used to determine the levels of seven trace elements, such as Cr, Fe, Cu, Zn, Cd, As and Se, using inductive coupled plasma mass spectroscopy (ICP-MS). The mean of serum catalase, paraoxonase activities and the concentration of Fe, Se, Zn, and Cd were significantly decreased, whereas the level of malondialdehyde (MDA) and the concentrations of Cu, Cd and As were significantly higher in type 2 diabetic group compared with the control group. The multivariate receiver operating characteristic (ROC) curve and variable importance in projection (VIP) scores were used to analysis the data. VIP score revealed that As, Fe and Se were strongly associated with the oxidative stress in type 2 diabetic patients. The best cut-off values for serum concentrations of Fe, Se and As were 46.78, 215 and 1.01 μg L-1, respectively, which discriminated between diabetic patients with oxidative stress from the control group. The study showed that changes in trace element concentrations in diabetic patients may contribute to the lowering of antioxidant enzymes t, further leading to the progress of T2DM.

Opis:

Podłoże po uprawie pieczarek (świeże, ang. spent mushroom substrate – SMS; kompostowane, ang. spent mushroom compost – SMC) stanowi odpadowy materiał organiczny z pieczarkarni. Zaliczono je do grupy odpadów z rolnictwa i innych jako „inny niewymieniony odpad”. Przy produkcji podłoża do uprawy tego grzyba wykorzystuje się, a jednocześnie utylizuje, odpady organiczne pochodzące z produkcji rolnej (dobrej jakości, o dużej zawartości węgla twardą słomę żytnią, pszenną, pszenżytnią, pomiot drobiowy – od brojlerów, kur niosek i indyków) oraz odpady mineralne z przemysłu (gips odpadowy z elektrofiltrów, fosfogips, CaCO³).
The chemical composition of spent mushroom substrate after cultivation of Agaricus bisporus from a modern, high performance mushroom hall in Siedlce region were determined. The substrate for cultivated mushrooms (ground + cover) came from different manufacturers. The dry matter content of the analysed spent mushroom substrate was average 36,5%, the reaction was mostly slightly acid or neutral (pH ranged 6,13-6,70), and content of the mineral nitrogen forms (N-NH4 i N-NOx) accounted for 1,24% of the total nitrogen, but it was several times more the ammonium nitrogen form. The total content of macroelements (N, Ca, P, Mg, Na) and same microelements (Co, B, Cu, Zn) was more then in the manure, with the most varied of the calcium content. The values of C:N ratio (average 12,3) was similar to the optimum levels in humus horizons of arable soils. The values of N:P:K ratio (2,6:1:1,8) indicated on deficiency of phosphorus and potassium. The content of heavy metals included in range allowing this waste material to fertilizer.

W doświadczeniu polowym badano wpływ nawożenia osadem ściekowym i nawozami mineralnymi (dla porównania) na zawartość wybranych pierwiastków: Fe, Mn, Mo, Li, Ti, Ba i Sr w biomasie trawy Miscanthus sacchariflorus w I i II roku uprawy. Doświadczenie założono w układzie całkowicie losowym, w trzech powtórzeniach. Zawartość ogólną wymienionych pierwiastków w suchej masie trawy oznaczono metodą ICP-AES po mineralizacji „na sucho”. W I roku doświadczenia zastosowany osad ściekowy w dawkach 20 i 30 Mg ha^–1 spowodował znacznie większą bioakumulację wszystkich badanych pierwiastków w porównaniu z obiektem kontrolnym. W II roku uprawy zanotowano więcej molibdenu, a mniej żelaza i tytanu niż w I roku; zawartość pozostałych pierwiastków była na zbliżonym poziomie w obydwu latach badań.
In a field experiment investigated the effect of fertilization with sewage sludge and mineral fertilizers (for comparison) on the content of selected elements: Fe, Mn, Mo, Li, Ti, Ba and Sr in the biomass of the grass Miscanthus sacchariflorus first and second year of cultivation. The experiment was a completely randomized, in triplicate. Total content of these elements in dry matter of grass was determined by ICP-AES after “dry” mineralization. In the first year of the experiment used sludge doses (20 and 30 Mg ha^–1) resulted in significantly higher bioaccumulation of all analyzed elements, compared with the control, in the first year of the experiment. In the second year of cultivation there was more of molybdenum, and less iron and titanium than in the first year, the contents of other elements were at a similar level in both years of study.

This paper examines and compares research activities in the field of lake sediment analysis for the period 2000-2009. The scientometric data is collected from 79 articles published in major journals included in the Science Citation Index (SCI). The most commonly used journals were Science of the Total Environment, Chemosphere, Microchemical Journal, Applied Geochemistry and Environment International. The trace elements which are analyzed in most cases are Pb, Cu, Ni, Cr, Co, Mn and Zn. None of countries show research effort activity that would be outstandingly higher than the majority, although some of them, eg Sweden, The United States, Canada and China have shown activity above the average level.

Opis:

Water is a significant source of macro - and microelements, necessary for the proper functioning of a human body. The purpose of this article was to analyze the quality of the selected bottled waters available on the Polish market in terms of the physico-chemical parameters (pH, conductivity, chloride ions, bromide ions), macroelements (sodium, potassium, calcium, magnesium) and trace elements (lead, nickel, antimony, arsenic). 17 brands of the bottled waters available on the Polish market were investigated within the study presented in the article (8 natural mineral waters, 6 spring waters and 3 therapeutic waters). The bottled waters, which were analyzed in the article, characterized with a large diversity of chemical composition. In two samples of therapeutic waters the permissible concentration of nickel was exceeded.

Opis:

Trace elements Co, Cr were added to investigate their influence on the microstructure and physical properties of Al-Si extruded alloy. The Co, Cr elements were randomly distributed in the matrix, forms intermetallic phase and their existence wereconfirmed by XRD, EDS and SEM analysis. With addition of trace elements, the microstructure was modified, Si particle size was reduced and the growth rate of β-(Al₅ FeSi) phase limited. Compared to parent alloy, hardness and tensile strength were enhanced while the linear coefficient of thermal expansion (CTE) was significantly reduced by 42.4% and 16.05% with Co and Cr addition respectively. It is considered that the low CTE occurs with addition of Co was due to the formation of intermetallic compound having low coefficient of thermal expansion. The results suggested that Co acts as an effective element in improving the mechanical properties of Al-Si alloy.

Opis:

The contents of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, S, V and Zn in road dust samples taken from the inside of seven road tunnels in the area ofWarsaw by ICP-OES technique were quantified. These deposits are characterized by high content of copper (ranging from 44 to387 mg/kg) and contents of chromium (15–36 mg/kg), nickel (9–17 mg/kg), lead (19–37 mg/kg) and zinc (101–258 mg/kg) increased in comparison to those typical of soils in the Polish Lowlands. In turn, the examined dust samples contain cadmium, cobalt and vanadium in concentrations close to the average for soils in this region.
