    Opis:
    The studied area of ca. 500 km2 lies within the Main Anticline and the Bytom-Dąbrowa Trough of the Upper Silesia Coal Basin. During the deposition of the fluvial Zabrze Beds, this area was subject to differential subsidence which resulted in gradual eastward thinning of this unit from ca. 250 m near Zabrze to ca. 4 m near Sosnowiec. Maps of net sandstone and coal contents in two stratigraphical intervals selected within the Zabrze Beds point to the presence of four channel tracts. The main tract is parallel to the NE-SW trending axis of maximum subsidence, and the other three are perpendicular to it. During deposition of the Zabrze Beds the main, NE-SW trending channel tract has shifted westward.

    Opis:
    The Lower Jurassic (Hettangian–Sinemurian) continental deposits of the Mehadia area (Caraş–Severin County) belong to the Presacina Basin, Upper Danubian Units of the South Carpathians, Romania. This un-named succession is exposed along large areas within the Greaţca Quarry where deposits of a complex braided river system can be seen. Nine clastic facies are identified within the Mehadia section and grouped into two facies associations reflecting two main sub-environments. (A) a fine-grained association, up to 6.5 m thick, composed of greyish black and dark grey massive and horizontally laminated mudstones interbedded with fine- to medium-grained sandstones showing ripple lamination, tabular low-angle large-scale cross-bedding and in some places massive sandstones. Within this association coarsening and fining-upward sequences are visible, while subordinate pensymmetrical-like sequences were observed. The sediments of the fine-grained association are interpreted as having been deposited along an alluvial plain from flood waters. The sandstone interbeds are interpreted as crevasse channel-fills and the thinner sandstone bodies as proximal crevasse splays. (B) a coarse-grained facies association represented by sandstones and conglomerates, both clast- and matrix-supported, from granule to pebble clast sizes. Almost all basal members of this association are underlain by erosional surfaces, while internal erosional surfaces occur at some levels. The coarse-grained facies association is interpreted as having been deposited within active river channels of a sandy braided river system. The occurrence of numerous erosional surfaces, the recurrence of the facies within this association (channel bodies), as well as the abundant mudstone and sandstone intraclasts all point to frequent conditions of erosion (including redeposition) of previously deposited sediments. The relatively low fine-grained sediment content (<25%) can be explained by two factors: (1) a creation rate for accommodation space was not enough for the accumulation of a large amount of overbank deposits; (2) a lack of larger quantities of fine-grained material being transported in the river system. Both factors may have operated independently or interacted.

    Opis:
    Authorship issues are clarified, new photographic documentation is provided and emended systematic descriptions are presented for the oldest Cambrian trilobite taxa from the Holy Cross Mountains (Poland). Biostratigraphic analysis of the fauna allows correlation with the traditional Holmia kjerulfi-group Zone of Scandinavia, the Callavia Zone of Britain and Newfoundland, the lower and middle part of the Sectigena Zone of Morocco and the Marianian Stage of Spain. The trilobites display a strong biogeographic signal linked with West Gondwana and Avalonia and a suggestion is made that the TESZ margin of Baltica with the Malopolska Massif was liable to currents from those areas that distributed planktonic trilobite larvae.

    Opis:
    The dinosaur footprints cf. Parabrontopodus isp. Lockley, Farlow et Meyer, 1994, attributed to sauropods, have been found in Hettangian (earliest Jurassic) alluvial deposits in Anina (Colonia Ceha Quarry, Resita Basin), belonging to the Getic Nappe in the Southern Carpathians, Western Romania. Heteropodous pes-manus sets and one short, narrow-gauge trackway have been recognized on a large sandstone surface trampled by sauropods. Agreater load was carried by the inner digits of the pes, particularly digit I, and the heel pad is deeply imprinted, which points to a sub-plantigrade pes and gravipodal posture, typical for Eusaropoda. A pentadactyl manus imprint suggestetthat manus digits of early sauropods might have been separate and perhaps more functional when supporting walking on unstable, sticky ground. These tracks, the first find of Jurassic dinosaur footprints in Romania, add an important site to the relatively rare record of earliest Jurassic sauropod footprints. These tracks also confirm that Pangaean islands and peninsulas around the Western Tethys were inhabited by early sauropods. These peninsulas or islands, including a hypothetical "Moesian Island", must have been at least temporarily connected with the mainland. The sizes of the Romanian footprints are similar to the Hettangian Parabrontopodus isp. tracks described from Poland (mainland Pangaea — Eurasian area) and Italy (Tethyan domain) and do not indicate insular dwarfism.

These are: an indirect method which includes extrusion of a pellet of elastomeric materiaL and a direct method which is a special case of a two-phase flow of paste and gas in pipe. A mathematical model of flow and a method for determination of the initial gas parameters, i.e. volume and pressure which enable the extrusion of pastes from pipeline, while preserving its technological and sensory properties, are proposed.

    Opis:
    Very large, sparsely distributed, sinuous, gently dipping and occasionally branching tunnels with subordinate swells, as well as possible chambers and scratches, are described from the Hettangian Dealul Budinic Member of the Lower Jurassic continental Steierdorf Formation at Anina in the South Carpathians, Romania, and are interpreted as tetrapod burrows. No bone remains have been found in association with these structures. The morphology and large dimensions of the burrows suggest that the trace-makers were sauropsid amniotes, most probably either crocodyliforms or small-sized basal neornithischian dinosaurs, although their therapsid affinities, despite being less likely, cannot be discarded either. The age, large size and probable origin of these burrows add important information to a poorly documented period of the evolution of tetrapod fossoriality. It may be suggested that within a relatively short time interval following the Triassic-Jurassic extinction event, when environmental conditions were still marked by strongly seasonal climate with prolonged droughts as well as extreme moisture and temperature fluctuations, fossorial habit probably became yet again an endurance strategy for burrow makers.

    Opis:
    Predomination of sandy bedload is typical of the anastomosing channels of the Narew River. Several types of in-channel accretionary macroforms have been found in these channels: side bars, concave-bank bars, plug bars, point bars, linguoid bars, and mid-channel bars. The first three types are relatively rare, point bars occur only exceptionally, while linguoid bars and mid-channel bars are quite common. The bars usually occur in main channels, which are the master routes of sand transport in the whole anastomosing system of the Narew. The lower parts of the bars are built of coarse- and medium-grained sand, similarly to the sediments in the deeper parts of the channels. Fine-grained sand, locally alternating with organic-rich muddy sand, predominates usually in the upper parts; peat with high content of sand is present in the highest parts of some bars. All bars are rapidly colonised and stabilised by plants. It is for this reason and due to the low energy of the river that the bar sediments have a high preservation potential. The development of bars is usually not accompanied by lateral migration of channels. Consequently, sediment accretion in bars is one of the factors leading to gradual narrowing of channels. Deposits of some sand-bars, when preserved in fossil record, may probably be represented by characteristic "wings" in the outer parts of ribbon-like sand bodies.

    Opis:
    The studied section of the upper Narew river is an example of an anastomosing system. It consists of a network of interconnected channels and interchannel areas covered with peat-forming rush and reed vegetation. The channels have low longitudinal gradient, are laterally stable, relatively deep, they have sandy bed and strongly overgrown banks. There are no natural levees built of clastic sediment. Straight-type channels dominate in the channel system. Meandering reaches lack discernible point bar topography. Vegetation plays an important role in the evolution of the anastomosing system of the Narew.
    Badany odcinek Narwi jest przykładem systemu rzeki anastomozującej. Składa się on z sieci rozdzielających się i ponownie łączących się koryt oraz z obszarów pozakorytowych, porośniętych roślinnością torfotwórczą. Koryta mają mały spadek, są stosunkowo głębokie i lateralnie stabilne, a ich brzegi są silnie zarośnięte. Większość koryt ma stosunkowo niewielką krętość, ale podrzędnie występują także odcinki kręte, typu meandrującego, pozbawione jednak dostrzegalnych łuków przyrostowych, charakterystycznych dla topografii odsypów meandrowych. Brak jest wyraźnie rozwiniętych wałów przykorytowych zbudowanych z materiału klastycznego. Roślinność odgrywa znaczącą rolę w rozwoju omawianego systemu.

    The aim of the study was to evaluate the contents of Cd, Pb, Zn and Cu in shoots of willow (Salix viminalis L.) cultivated in the vicinity of a coal ash and slag landfill. The landfill is surrounded by arable lands and meadows. There are two major negative influences of the landfill - dusting and flooding. The result of these interactions is the systematic reduction of agricultural value of the land. A field with an area of 9600 m2 were chosen. The land is located east to the landfill. A total of 40 samples of biomass was collected. The contents of analysed elements were determined by FAAS using a Unicam Solaar M6 spectrometer. Distance from the landfill affects the contents of Cd, Pb, Zn and Cu in the tested willow shoots. However, there is no single concentration pattern for all the investigated metals. An increase in willow cultivation on the described area can bring a good environmental effect and become an example of proper management of the ash and slag landfill neighbourhood.

    The aim of the study was to compare the levels of cadmium and lead in livers, kidneys and wool / hair / of sheep and goats reared in the vicinity of the steelworks in Nowa Huta in Kraków and in the control field, Rożniatów, in which there was no emitters of heavy metals. Samples were collected post mortem from one-year old animals of one breed (within a species) and one sex, who had lived from birth in the studied areas. Both species were fed with the same fodder and have remained in the same places. Wet mineralization was applied (mixture of nitric acid (V) and chloric (VII) (3: 1)) metal determination was done by a FASA method. The levels of the metals depend on the species, on the test areas and on the collected part of the animal. Tissues from sheep contained more cadmium and lead than the tissue of goats. The highest cadmium content was found in the kidney, lower in the liver, the lowest in the hair / wool of tested animals. Goat kidneys from both areas of research and sheep kidneys from Rożniatów meet consumer standards for cadmium. However, 20% of sheep kidneys sampled from Nowa Huta district exceeded the standards for cadmium. The lead content of both species exceeded the limit in all of the kidneys and livers from Nowa Huta district. In Rożniatów the standards were not fulfilled for all kidneys and livers of goats, and all kidneys and 70% of the livers of sheep.

    Opis:
    Stability of the polypropylene composite with fiber glass (45/55) in the form of low density mat was tested experimentally at increased temperature. It was examined by analyzing the influence of the atmosphere with various oxygen content on the decomposition rate of the polypropylene composite. It has been found that in the air atmosphere, the initial decomposition temperature is close to 200 oC. Lowering the oxygen concentration in the atmosphere to 2 % results in increase of composite decomposition temperature to almost 240 oC. Decomposition components were identified in the methylene chloride extract from composite and in the condensed reaction products. Rate of decomposition conversion at initial stage below 0.2 was estimated as a system of equations: zero order path r = k1 for polypropylene degradation and first order path r = k2[O2] for oxidative decomposition. A brief safety analysis is performed identifying the possibility of exceeding an explosion limit under certain conditions. The best way of mitigating the fire/explosion hazard is lowering the oxygen content below 2 % vol., especially for processing of recycled polypropylene.
    Sprawdzano doświadczalnie wrażliwość kompozytu polipropylenu, w postaci maty o niskiej gęstości upakowania, na działanie podwyższonej temperatury. Wrażliwość oceniano, analizując wpływ atmosfery o różnej zawartości tlenu na temperaturę początku rozkładu kompozytu polipropylenu z włóknem szklanym o składzie zbliżonym do 45/55. Stwierdzono, że w atmosferze powietrza, początkowa temperatura rozkładu wynosi ok. 200 oC. Obniżenie stężenia tlenu w atmosferze do ok. 2 % powoduje wzrost temperatury rozkładu kompozytu do ok. 240 oC. Produkty rozkładu zidentyfikowano w kondensacie oraz ekstrakcie kompozytu w chlorku metylenu.

    Opis:
    Coal combustion ash-slag mixtures have been deposited in landfills in Poland for decades. At the same time, there is a shortfall in the amount of available materials related to the construction and modernisation of transportation infrastructure. Thus, a typical landfill of a power station was chosen and the aim of the study was to assess the suitability of an ash-slag landfill mixture for construction engineering purposes. The following physicochemical analyses were conducted: pH, specific electrical conductivity and determination of the leachability of basic (Ca, Na, K and Mg) and trace elements (Cd, Pb, Cr, Zn and Cu). The content of selected basic and trace elements were determined in the eluates by FAAS and standard methods were applied for geotechnical analyses. The most likely conditions were assumed to the model. The mixture will not jeopardize surface water quality in terms of the concentrations of basic, hazardous or priority elements. The content of these elements also does not exceed permissible concentrations for groundwater. The conductance and pH of the eluates are in compliance with current laws. The solid mixture has favourable geotechnical parameters which are significantly dependent on moisture content. The slope stability calculations for embankments created from the mixture at optimum moisture content and high compaction (Is ≥ 0.95) indicate that they will be stable even in the case of high gradients (1:1.5). The slopes will be unstable in conditions of submersion, which should not occur if we assume the embankment will be used for passive flood protection

Two distinct phenomena are observed: increased dust concentration in the air and excessive soil moisture or even flooding. The aim of the study was to assess whether and to what degree the landfill affects the content of the trace elements Cd(II), Pb(II), Zn(II) and Cu in the soil and plants of the adjoining agricultural production areas. The content of Cd(II), Pb(II), Zn(II) and Cu in the soil of the studied area was within the acceptable norms specified in the regulation of the Ministry of the Environment (Dz. U. 2002 nr 165, poz. 1359). In the herbaceous vegetation growing at sampling points W150, E150, E100 and N100, the acceptable level of Cd(II) specified in the regulation of the Ministry of Agriculture and Rural Development exceeded the norms (Dz. U. 2012 poz. 203). In turn, all the plant samples Pb(II) showed acceptable levels. The content of Zn(II) and Cu in the plant material meets the criteria for fodder proposed by IUNG (Kabata-Pendias et al. 1993). The high phytoaccumulation indices for Cd(II) and Zn(II) in the plant material may be due to dust fall containing metals. However, without precise quantitative and qualitative measurements of dust fall, it is difficult to ascertain to what extent this is caused by migration from the landfill and to what extent it is a result of deposits of pollutants from other sources.

    Opis:
    Selected research polygon is located in Trzebinia commune in the mid of the 80 km way from Kraków to Katowice (the Upper Silesia capital). The towns of Trzebinia, Chrzanów within the towns of Krzeszowice, Jaworzno, Mysłowice, have been creating a base of well-connected Kraków-Upper Silesia agglomeration. The inhabitants of Trzebinia commune are flexible on labour market, often commute to work in Kraków or Katowice. They have detached houses with gardens of one or two acres size, where "home-made", fresh, low-processed food could be produced. At the same time the area of Trzebinia Community belongs to Chrzanów geochemical anomaly, which is reflected in high values of cadmium, lead and zinc contents in the soils. This is the result of both natural and anthropogenic factors. The purpose of the paper was to evaluate lead and iron contents in roots and leaves of parsley being cultivated within the area of the anomaly. Considering, there is a positive geochemical anomaly, the lead contents in soil were low - the average value was 88.67 mg kg -1 d.m. and only two contents -218.98 and 119.35 exceeded 100 mg kg -1 d.m. On the other hand the lead contents in parsley roots were high, many times higher than the allowable values. The lead contents in parsley leaves were also high. Phytoaccumulation indices low, only one had the average value, but at their minimal range (1.02 and 10.3 adequately for leaves and roots). Translocation index of lead was close to one. The iron contents in soils were not high and fall within the scope of low and average ranges that occur in Polish soils. The iron contents in leaves were high, attractive from nutrition point of view.
