    Opis:
    The research areas were selected in the regions heavily polluted by wastes from the former washing plant, flotation waste dump and by non-sulphide Zn-Pb ores from open pit mining in the Olkusz region. The submicroscopic phases occurring in the surface of plant roots and in the rhizospheres were investigated by XRD and SEM/EDS methods. Morphology of submicroscopic metalliferous phases and their manner of occurrence were the subject of study. The analysis of EDS spectra enabled to identify phases and mineral aggregates including Zn, Pb, Fe, Mn, Cd in their structure. The soils from the washing plant and areas of open pit exploitation are contaminated by diverse complexes of minerals. The occurrence of unstable Fe, Pb, Ca sulphates indicate that these wastes are still intensively geochemically active.

    Opis:
    The problem of environmental pollution with heavy metals is still serious, despite numerous activities related to the reduction of anthropogenic emissions of these elements into the environment. There is a growing concentration of many toxic metals in soils and vegetation (remaining in close relation with the state of air quality), and especially in the environment of large urban agglomerations. The paper presents an assessment of the degree of contamination of soil and grass vegetation with heavy metals (Zn, Pb, Cu, Cd) in the vicinity of the communication over Warsaw. Research material obtained from the same locations (samples of soil and grass vegetation) was analyzed (AAS) in terms of the total concentration of metals in soils and its mobile form, while in plants is the total concentration of the corresponding trace the AAS atomic spectrometry. Based on the concentrations of metals in soil and vegetation samples were determined bioaccumulation factors. Methods mobile metals isolated by selective extraction of a 0.05 M EDTA solution. The results obtained were related to the results of similar research conducted two years earlier in 2005. Additionally the effect of leaching of soluble forms of metal particulate pollutants deposited on the surface of vegetation.

    Opis:
    The aim of the studies was to determine the influence of copper and zinc contamination on clopyralid dissipation in soil. The experiment was carried out in laboratory conditions (plant growth chamber). Clopyralid was applied to three different soils [similar textures, pH, organic carbon content and contrasting copper and zinc content: soil natural contaminated with Cu and Zn (S1), soil with natural low Cu and Zn concentration (S2) and soil S21 prepared in the laboratory (S2 soil additionally contaminated with Cu and Zn salts in the amounts equivalent to contamination level of S1 soil)]. Soil samples were taken for analyses for 1 hour (initial concentration) and 2, 4, 8, 16, 32, 64 and 96 days after treatment. Clopyralid residue was analysed using GC/ECD (gas chromatography with electron capture detector). Good linearity was found between logarithmic concentration of clopyralid residues and time. The differences in Cu and Zn content influenced the clopyralid decay in soil. The values of DT50 obtained in the experiment ranged from 21 to 27 days. A high concentration of Cu and Zn in soil slowed down clopyralid degradation (the DT50 value was higher – 25–27 days).

    Opis:
    W artykule przedstawiono wyniki badań mineralogicznych i chemicznych kruszywa sztucznego wyprodukowanego na bazie starych odpadów z hutnictwa Zn-Pb. Skład mineralny zdominowany był przez minerały powstające w procesie hutniczym w wyniku oddziaływania wysokiej temperaturze (pirokseny, plagioklazy, mulit, magnetyt, spinele) oraz minerały wtórne powstałe w wyniku procesów hipergenicznych (gips, węglany). W składzie chemicznym dominowały: SiO2, Fe2O3, CaO, MgO a także Al2O3. Stwierdzono także wysoką zawartość Zn, która dochodziła nawet do 5,5%. Inne zidentyfikowane pierwiastki występujące w kruszywie to między innymi: Pb, Mn, Cr, Ni, Cu, As, Sr, Sb. Przeprowadzone testy wymywalności wykazały, że ilości metali jakie przechodzą do eluatu przekraczają dopuszczalne normy.
    The paper presents results of mineralogical and chemical studies of artificial aggregate produced on the basis of the old metallurgical Zn-Pb wastes. Mineral composition is dominated by minerals formed during metallurgical process as a result of high temperature interaction (pyroxene, plagioclase, mullite, magnetite, spinel) and secondary minerals formed as a result of hypergenic processes (gypsum, carbonates). In the chemical composition SiO2, Fe2O3, CaO, MgO dominate, but also Al2O3. The high concentration of Zn (even 5,5%) were also observed. Other elements identified in the artifical aggregate are: Pb, Mn, Cr, Ni, Cu, As, Sr, Sb. The leaching tests showed that the amounts of elements which were leached to the eluates exceed standards.

    Opis:
    Assisted phytostabilisation involves the use of plants and soil additives for physical stabilization of the soil and chemical immobilization of contaminants. This technique aims to establish a vegetation cover with metal-tolerant plants and thus reduce leaching of metals. The main aim is to reduce the risk of incorporation of metal into the food chain. In the conducted experiment contaminated soil was collected from the area surrounding a zinc smelter in Miasteczko Slaskie, in the Silesia region of Poland. Soil in the study area has been contaminated with metals, especially Cd, Pb and Zn. Moreover, soils of the study area are also acidified. The role of sewage sludge and inorganic amendments as an immobilising agents in the attenuating phytostabilisation of metal-contaminated soil was evaluated using grass species Festucaarundinacea Schreb. The biosolid used was anaerobically digested sewage sludge, collected from the industrial waste water treatment plant and juices manufacturer (food industry). The soil was mixed with sewage sludge (sewage sludge accounted for 1and 3% of dry weight), lime and inorganic fertilizers (potassium phosphate, TSP at 0.8% each). A plant growth experiment was conducted in a growth chamber for 10 weeks. The plants were grown under artificial conditions, suitable for proper growth of plants. Plants growing on amended soil were devoid of any macroscopic symptoms of metal toxicity or nutrient deficiency, in contrast to plants grown on non-amended soil, where growth was inhibited and some phytotoxic effects were observed. For amended soil, plant growth was most likely influenced by improved soil conditions due to nutrient-rich amendments and metals immobilisation. Mobile fractions of metals decreased in amended soil, and the same pattern was observed for metal concentrations in plant tissues. However, the best results were obtained for the variants of combined application of sewage sludge and inorganic amendments. All investigated metals accumulated mainly in root tissues in combination with sewage sludge application. A significant reduction in metal uptake by plants was achieved after sewage sludge application, which is attributed to decreased bioavailability and the stabilisation of metals in soil. In the experiment the introduction of soil liming treatment allowed to maintain the pH at a constant level after 10 weeks of the experiment (5.5–7) (Fig. 1). The K5-K10 variants achieved a significant reduction in bioavailable forms (0.01 M CaCl2 extraction). In a study of biomass (Fig. 3) the highest yield (5.5 g DM) was obtained for the combined use of a combination of potassium and phosphate deposits and combinations of superphosphate and combined use of sewage sludge (2.5 g DM/pot). The highest immobilization effects were obtained for combined application of sewage sludge, lime fertilizer and superphosphate or potassium phosphate as compared to other options. The highest degree of immobilization of three tested heavy metals: cadmium, zinc and lead was obtained only with the application of sewage sludge and mineral amendments at a dose of TW +FP 0.8% + 1% d.m. sewage sludge. Effective process of chemophytostabilisation with the use of grass and organic additive and inorganic additives in situ sandy areas and heavily contaminated with heavy metals, can be obtained solely with the combined use of investigated additives and treatment.

    Opis:
    This study aimed at determining the level of pollution from heavy metals that are deposited from air in the area of Gllogoc. The main goal was to identify the emission sources of pollution by using mosses as bio indicators. In this study area, the mining of Fe-Ni (Industrial Ferronickel Complex) is believed to strongly influence the level of heavy metals. The mining and production activity of Fe-Ni affects the soil, water and air. As the air pollution (from liberated aerosols of Industrial Ferronickel Complex) and the deposition products of this pollution are harmful not only locally but also can pollute the environmental at extended distances, the use of mosses allows analyzing the content and origin of the pollution from heavy metals. ICP was used for the determination of heavy metals in moss samples. The use of Principal Component Analysis (PCA), dendograms and other statistical procedures, permitted to understand the source of the air pollution from heavy metals.

    Opis:
    As a solid waste, the associated disposal cost of fly ash is really high. Previous studies suggested that the utilization of fly ash to treat heavy metal-contaminated soils was a new cost-effective method of disposal of it. Therefore, the effectiveness of fly ash stabilized/solidified Zn-contaminated soils has been investigated by unconfined compressive strength (UCS) and toxicity characteristics leaching procedure (TCLP) tests. Quantitative analysis of the soil microstructure was conducted by processing the X-ray diffraction (XRD) and scanning electron microscope (SEM) images. Mercury intrusion porosimetry (MIP) was carried out to illustrate the size and proportion of pore size for specimens under different ratios. The results of the tests showed an improvement in the UCS, which further increased as the content of binders was raised. Binder content would have little influence on the development of strength if the binder content exceeds a threshold value. The leached Zn2+ concentration of stabilized specimens was significantly decreased compared to that of untreated. Quantitative analysis confirmed that the addition of the binders resulted in the amount of hydration product, reduction of porosity, and a really random pores orientation, which was responsible for the improvement of the strength and leaching properties of the Zn2+ contaminated soils.

    Opis:
    The aim of that publication was the presentation of previous and planned research concerning selected vascular plants and soils near Olkusz (Southern Poland). The extremely high concentration of heavy metals in soils from that region was caused by the natural geochemical aureoles of dispersed metals (due to weathering of Zn-Pb-Fe ore sulphides) and mining and processing of shallowly occurring metalliferous deposits (containing Ag-Pb and Zn-Pb ores) since XII century. The condition of stress in metals, shortage of water and some plant nutrition led to formation of some adaptable vegetation features by plants growing in that region. Some species called metallophytes have been already detailed investigated. Moreover some geochemical and pedological research of soil have been already done. However the conditions of habitat of pioneering species such as Koeleria glauca and Corynephorus canescens are not still recognized.

    Among a number of climate-related factors, moisture has the greatest impact on crop productivity. In recent years, certain changes have been observed under conditions of the Forest-Steppe of Ukraine with regard to precipitation – from low to in some cases – abnormally high, which requires the study of their impact on the yield and safety of cereal grain for its forecasted production. The article examined the effect of a high level of soil moisture (256.2–272.5 mm) and a low level (47.4–52.3 mm) during the growing season (germination→earing) of spring barley grain on the accumulation of heavy metals in it and its productivity under the conditions of gray forest soils of the Right Bank Forest Steppe of Ukraine. Spring barley varieties Helios and Caesar were selected for the research. A decrease in the accumulation coefficient at a high level of soil moisture (256.6–272.5 mm) in spring barley grain Pb from 8.3% to 11.3%, Cd – from 35.0% to 35.5%, Zn was established – by 15% and Cu – from 11.2% to 16.6% compared to the low level of soil moisture (47.1 mm – 53.3 mm). At the same time, it was found that with a high level of soil moisture, there is a decrease in the yield of Helios and Caesar spring barley by 18.0% and 14.1%, respectively.

    Opis:
    The paper presents results of studies on storm-generated surface runoff, a phenomenon belonging to the least known factors responsible for migration of pollutants to water environment. The results of determinations of pH, conductivity as well as content of Ca, Zn, Cd, and Pb are found to be useful as the main indicators of pollution spread by waters running from dam slopes of pond in which tailings from flotation of Zn-Pb ore are disposed. Rain water leaches fine fractions of carbonate-sulfate wastes (represented mainly by dolomite, 73%, and Fe sulfides – marcasite, up to 20%) which leads to change in character of surface runoff water to that of SO4-Ca hydro-chemical type. Among the leached metals significantly important for the environment are Zn, Cd and Pb whose concentrations exceed threshold values for surface and/or groundwater of IV quality class. Acceptable concentrations in waste waters are frequently exceeded by sulfates and incidentally by zinc. Variability of the analyzed concentration indices from the years 2008 and 2009 indicates influence of weather conditions on chemical composition of surface runoff water from slopes of tailings pond of flotation plant of MVT ores.
