    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.

    heavy metals
    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:
    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:
    Phytochelatins (PCs) exist widely in plants and are closely related to plant resistance to heavy metals (HMs). Glutathione (GSH) and nonprotein thiols (NPTs) are the major components of PCs. This study investigates the role of the PCs of Cladophora rupestris in Pb2+ accumulation and detoxification. The distribution of Pb2+ in the PCs of C. rupestris was studied. FTIR and XPS are used to characterize the chelating power of Pb2+ with PCs in C.rupestris. The curve fitting of the secondary protein structure is used to identify the functional groups with Pb2+. Results showed that the content of Pb2+ in the PCs of C. rupestris increased with an increase in Pb2+ stress. Pb content increased to 352 and 314 mg/kg in NPTs and GSH, respectively, when Pb stress concentration reached 7.5 mg/dm3 . The Pb2+ fraction of C. rupestris PCs reached a maximum of 10.8 and 9.3% in NPTs and GSH, respectively. The Pb2+ uptake by GSH and NPTs was 40–48% and 52–60%, respectively. Pb2+ bound with the PCs of C. rupestris, forming complexes that contained Pb–OOC, Pb–C=O, CO–Pb, –N=Pb, Pb–NH2, Pb–O, Pb–N–, Pb–C–, Pb–S, and Pb2+ with multiple groups of PCs as bridging ligand atoms.

    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:
    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.

    Opis:
    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.

    Opis:
    Mass balance of selected heavy metals (Cu, Cr, Pb, Hg, Zn, Cd) released from waste into leachate during 8 years of landfill exploitation has been calculated. The average release of all analyzed heavy metals did not exceed 1.7%. Heavy metals released in the largest quantities were Cr (0.025 –1.685%), Hg (0.033–1.540%) and Cd (0.082–0.701%). Release of Pb, Cu, Zn was 0.008–0.152%; 0.012–0.085% and 0.007–0.152%, respectively. Cr and Hg do not form an insoluble sulfide precipitate and that is why they are released in a larger amount. Cd and Pb concentrations are positively correlated with the amount of the atmospheric precipitation and the amount of leachates, which means that infiltrating rainfall can leach out these metals from waste. Favorable conditions for leaching of these metals are probably a result of their precipitation as carbonates. A strong correlation between Cu, Zn, and Cr indicates they do not precipitate as carbonates and further they can be subject to desorption processes. In the case of Cu, Zn, Cr and Hg, a positive correlation with the amount of deposited waste was also observed.
