    Opis:
    The last study on n-alkanes in surface sediments of Taihu Lake was in 2000, only 13 surface sediment samples were analysed, in order to have a comprehensive and up-to-date understanding of n-alkanes in the surface sediments of Taihu Lake, 41 surface sediment samples were analyzed by GC-MS. C10 to C37 were detected, the total concentrations of n-alkanes ranged from 2109 ng g−1 to 9096 ng gg−1 (dry weight). There was strong odd carbon predominance in long chain n-alkanes and even carbon predominance in short chain n-alkanes. When this finding was combined with the analysis results of wax n-alkanes (WaxCn), carbon preference index (CPI), unresolved complex mixture (UCM), hopanes and steranes, it was considered that the long chain n-alkanes were mainly from terrigenous higher plants, and that the short chain n-alkanes mainly originated from bacteria and algae in the lake, compared with previous studies, there were no obvious anthropogenic petrogenic inputs. Terrestrial and aquatic hydrocarbons ratio (TAR) and C21−/C25+ indicated that terrigenous input was higher than aquatic sources and the nearshore n-alkanes were mainly from land-derived sources. Moreover, the distribution of short chain n-alkanes presented a relatively uniform pattern, while the long chain n-alkanes presented a trend that concentrations dropped from nearshore places to the middle of lake.

    Opis:
    The research concerned flow-through reservoirs fed with contaminated river water. The aim of the research was to recognize the impact of reservoirs on fluvial transportation of contaminants. Three reservoirs, situated in the Upper-Silesian region (southern Poland) and operating in different environmental conditions, were selected for the research: Pogoria I reservoir - operating in the quasi-natural direct catchment (with fluvial load of industrial-municipal wastewater), Przeczyce reservoir - under agricultural anthropopressure, and Dzierzno Due reservoir - under urban-industrial anthropopressure. The research included analyses of the quality of river water flowing into and leaving the reservoirs and calculation of contaminant loads at the inflows and outflows. The research showed that Pogoria I reservoir neutralised inflowing contaminants, thus purifying the river water. Nitrogen and phosphorus compounds were particularly efficiently retained. Electrolytic conductance of water in Pogoria was reduced by up to 50%. Przeczyce reservoir was alimented with eutrophic water (especially rich in biogenic elements) from agricultural land. The reservoir accumulated contaminants at the initial stage of the research. After several years, however, it started releasing some of the accumulated substances, causing an increase in contamination of river water with e.g. organic substances. The data concerning Przeczyce reservoir revealed that reservoirs can purify water from some substances and simultaneously cause an increase in contamination with other substances. Selectivity of hydrochemical impact of reservoirs was particularly visible in case of Dzierzno Due reservoir, which received wastewater from the urban-industrial catchment. It largely reduced the loads of suspended matter, phosphates or zinc, among other substances, at the same time causing secondary contamination with substances like ammonia, lead or cadmium. The results of the research show individuality of reservoirs in terms of their impact on fluvial transportation of substances. It might be believed, however, that each reservoir which is fed with contaminated water will have at least partly (selectively) contaminating impact in the course of time. That should be related to increasing eutrophication in conditions of limited capacity of accumulation of contaminants in the limnic environment. Detailed assessment of transfer of substances by a particular reservoir would require individual research for that reservoir.

    Opis:
    The first geological and engineering investments in Lublin related to the defense and the isolation of the castle can be dated back at least 700 years. Today, the oldest ones among them are documented only during archaeological excavations in the areas of hills/promontories in the eastern edge of loessic Na³êczów Plateau, steeply sloping down to the valley of Bystrzyca River. Over the centuries, the growing town, required number of investments conditioned by the geology (surface rocks) and relief. The city expanded to the areas of different in geology and topography. As a result of geotechnical works, implemented over several hundred years, modern Lublin is the town that could boast a number of multiage and diverse geotechnical objects. These are primarily objects designed to serve the defense, streamlining communication and also widely understood economy.

    The study aimed at the evaluation of the quality of bottom sediments and evaluation of potential threat to the aquatic environment. Cadmium, cobalt, chromium, copper, nickel, lead, zinc and mercury concentration in the separate layers of the sediments in the pond at Żelisławiec decreased with the depth of bottom sediments. On the other hand, the highest concentrations of the studied elements occurred in the deepest layer of sediments in the pond at Stare Czarnowo. The level of the potential ecological risk (PER) for the sediments of the Żelisławiec pond classifies them as sediments with low quality of the potential ecological risk, whereas the sediments from the pond at Stare Czarnowo are classified as moderate level of the potential ecological risk. In both ponds, the highest Igeo values were reported for zinc and lead.

    Artykuł przedstawia wyniki analiz wybranych wskaźników chemicznych osadów dennych wód Raszynki, jej dopływów oraz Stawów Raszyńskich. Odczyn osadów w większości przypadków jest obojętny lub lekko kwaśny, optymalny dla rozwoju fauny i flory środowiska wodnego. Przeważają osady mineralne lub z domieszką substancji organicznej. Zawartość azotu ogólnego i pojemność sorpcyjna zależą od pojemności substancji organicznej w osadach. Osady nie są skażone chemicznie.
    The article presents results of analyses of selected chemical indicators of the bottom depo sit taken from the Raszynka River, its tributaries and several ponds located in the catchment. Reaction (pH) of the sediments was mostly neutral or slightly acidic – optimum for the growth of aquatic flora and fauna. Mineral sediments with small admixtures of organic matter prevailed. Concentration of total nitrogen and sorption capacity depended on the content of organic matter in the sediments. The analysis indicate that contamination of the bottom sediments does not exceed standards.

    Opis:
    Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) are unwanted by-products in a variety of industrial and thermal processes. They have been present on Earth long before the human era, since they may be also formed as a result of forest fires or volcanic explosions. Polychlorinated biphenyls (PCBs) in turn, have been intentionally produced by humans. Poland was a minor producer of PCB mixtures (Chlorofen and Tarnol), which were a source of direct and indirect environmental diffusion with PCB and less with PCDDs/PCDFs. Industrial accidents with PCDDs/PCDFs were absent in Poland. Their stability and resistance to thermal breakdown made them very dangerous for environment and, in consequence, due to their environmental persistence, bioaccumulation and biomagnification in the terrestrial and aquatic food chains, to humans. Humans may become affected by PCDDs/PCDFs and PCBs through environmental (soil and water contamination, fish and food), occupational (incinerators; pulp, paper and metallurgy industry; copper production), or accidental (Seveso accident) exposure. The aim of this review was to evaluate environmental hazard caused by PCDDs, PCDFs and dioxin-like-PCBs in the central region of Poland based on the accessible data on diffusion of those compounds in sediments and riverine, reservoir and storm water from our previous studies and discussed in the context of other achievements in Poland and elsewhere.

    Opis:
    The aim of this study was to determine and to evaluate heavy metals (Cd, Cu, Pb, Zn) concentrations in sediments of “Korytow” reservoir, located on Pisia-Gagolina river. In analyzed sediments concentrations of heavy metals was diversified due to their natural concentrations. Concentrations of Zn, Cu, Cd in upper layers were lower than concentrations in lower layers which means, that mean concentration of this metals in sediments is reducing. Concentration of Pb was balanced (117.1 mg/kg) in each sample core. Mean Pb concentration is much higher than natural geochemical background. Results of this work shows that concentration of toxic metals (Cd and Pb) in sediments was high. It confirms that water environment is polluted by heavy metals.
    Celem badań było oznaczenie zawartości Zn, Cu, Pb i Cd w osadach dennych zbiornika Korytów, zlokalizowanego na rzece Pisi-Gągolinie. W prowadzonych badaniach obserwowano duże zróżnicowanie stężeń czterech metali w odniesieniu do ich naturalnej zawartości. Stężenia Zn, Cu i Cd w warstwie powierzchniowej osadów były niższe niż w głębszych warstwach, co świadczy o redukcji średniej zawartości metali w osadach. Zawartość ołowiu była wyrównana w głąb osadów (117,1 mg/kg), przekraczając znacznie poziom tła geochemicznego środowiska. Na podstawie uzyskanych wyników można stwierdzić, że osady charakteryzowały się wysoką zawartością toksycznych metali (Cd i Pb). Potwierdza to znaczne zanieczyszczenie środowiska wodnego metalami.

    Opis:
    The sub-Quaternary topography of the western Sandomierz Basin has been compared to variable thicknesses of Quaternary sediments and geomorphology of the area. The lithology and age of the top of Miocene strata have been determined. The Witów Series has been interpreted as a sequence of a braided river that used to flow into the retreating marine basin, forming a fan delta whose age, according to macrofloristic determinations, has been assigned to the Late Miocene. Lower Quaternary gravels cap the remnants of a planated surface situated at 240-250 m a.s.l. The Błonie gravel horizon occurring at a similar altitude was deposited by a river active in Narevian and/or Nidanian glacial stages, and its top underwent reworking during the Sanian-2 stage. Deposits infilling the fossil sub-Carpathian Furrow have been mapped and dated to the Cromerian s.l. interglacial stage. The final alluviation of this segment of the furrow took place during the Sanian-2 stage. Reconstruction of the drainage pattern during the Eopleistocene, South-Polish glaciations, and Masovian inter- glacial stage has been proposed as well.

    Opis:
    The paper presents the results of study on influence of „Góra Żbikowska” landfill on surface water and bottom sediments of part of the Utrata river. This landfill pile is located in south-west part of Warsaw agglomeration. The results were considered in relation to the influence of old landfills on water environment. The tested parameters were: concentrations of metals in bottom sediments (8 sites) and physio-chemical parameters of water (2 sites) pointing to significant pollution of both mentioned components of water environment. The bottom sediments collected from the site located nearby „Góra Żbikowska” landfill (site number 7) contained the highest concentrations of heavy metals. In this site particularly high concentration of copper was found, furthermore this concentration exceeded the third class of bottom sediments purity (in accordance with geochemical criteria) [11].The metals in bottom sediments presumably come from the period when the landfill was not sufficiently isolated, but further ex tended analyses are needed to prove this statement, as well as confirm the necessity of the landfill closure and efforts for reclamation of the whole area surrounding the pile, including part of river.
    Praca dotyczy wpływu czynnego składowisku odpadów innych niż niebezpieczne i obojętne „Góra Żbikowska” na wody oraz osady denne odcinka rzeki Utraty. Składowisko położone jest w południowo-zachodniej części aglomeracji warszawskiej. Wyniki badań były rozpatrywane pod kątem oddziaływania składowisk odpadów na środowisko wodne. Zbadane parametry, tj. stężenia metali w osadach dennych (8 stanowisk) oraz parametry fizykochemiczne wody powierzchniowej pobranej z dwóch punktów położonych w niedalekim sąsiedztwie składowiska, wskazują na znaczne zanieczyszczenie obu badanych komponentów środowiska wodnego. Największe stężenia metali stwierdzono w osadach dennych pobranych ze stanowiska nr 7. Szczególnie wysokie stężenia dotyczyły miedzi, przekraczały one bowiem (zgodnie z kryteriami geochemicznymi) III klasę czystości [11]. Opisane wyniki mogą posłużyć za podstawę do przeprowadzenia szerszych i aktualniejszych badań oddziaływania omawianego składowiska odpadów na jakość wód i osadów dennych rzeki Utraty. Powtórzenie badań na zaproponowanych w pracy stanowiskach, może pozwolić na potwierdzenie konieczności zamknięcia składowiska i rekultywacji terenu lub wykazać, że metale ciężkie w osadach dennych pochodzą głównie z okresu, w którym składowisko nie było dostatecznie zabezpieczone.

    Opis:
    The near-surface geochemical survey of gases desorbed from sediment samples was carried out in the area of an abandoned ozokerite mine in Starunia, where remnants of mammoth and three woolly rhinoceroses and one almost completely preserved rhinoceros carcass were discovered in 1907 and 1929. Numerous hydrocarbon seeps (gas and oil "eyes") occur on the surface of the study area. Analyses of molecular and stable carbon isotope compositions of adsorbed gases were carried out in two variants. The first included sampling of cuttings from 30 auger boreholes at depths of 4.8, 5.6 and 6.4 m. In total, 88 samples were collected. In the second variant core samples were collected from 17 selected boreholes. In total, 78 samples were taken from various depths to 12 m. The results of molecular composition analyses of desorbed gases indicated high saturation of near-surface sediments with the oil. The highest concentrations of alkanes were detected in Miocene strata. Hydrocarbon migration from deep accumulations to the surface was relatively fast and proceeded along the faults, fractures and cracks. In the near-surface zone hydrocarbons were subjected to oxidation and dehydrogenation, which resulted in generation of unsaturated hydrocarbons and hydrogen. These processes were most intensive in the Pleistocene sediments and in the mine dumps. Increased concentrations of hydrogen may also originate from water radiolysis in the presence of hydrocarbons. Concentrations of carbon dioxide in the adsorbed gases show the higher values in comparison with the analysed gaseous compounds. However, a slight increase in CO2 concentration was detected in the mine dump, which may indicate conditions more favourable for hydrocarbon oxidation. Carbon dioxide from the analysed adsorbed gases is of thermogenic origin. Occasionally, insignificant influence of secondary hydrocarbon oxidation and/or Quaternary organic matter can be observed. Concentrations of alkanes, alkenes and carbon dioxide in the gas derived from desorption of rock samples are lower and the concentration of hydrogen is higher than those measured in free gases. This indicates that additional effects from recent (e.g. microbial) processes are absent.

    Opis:
    Near-surface gases were investigated in Starunia, where remains of mammoth and woolly rhinoceroses were discovered at the beginning of the 20th century. Samples were collected at 30 measurement sites, from 0.8, 1.6, 2.4, 3.2 and 4.0 m depths and analysed for their molecular and isotopic compositions. Most of the methane and all higher gaseous hydrocarbons accumulated within the near-surface zone are of thermogenic origin. The distribution of thermogenic methane and higher gaseous hydrocarbons in Quaternary sediments is variable and, generally, increases with depth. Microbial methane or a mixture of microbial and thermogenic methane also occurs at the near-surface zone. The presence of hydrogen and alkenes in the near-surface gases also suggests a contribution from recent, microbial processes. Helium of crustal origin migrated through the Rinne Fault and other tectonic zones located in the study area, and was subsequently dispersed during migration through the lithologically diversified Pleistocene and Holocene sediments. The high variability of the carbon dioxide concentration and stable carbon isotope composition at various depths in the near-surface zone is caused by its polygenetic origin (thermogenic, microbial, and oxidation of hydrocarbons and Quaternary organic matter), and also by its dissolution in water and oil during migration through lithologically diversified Pleistocene and Holocene sediments. Zones of thermogenic methane occurrence within Pleistocene sediments, dominated by muds saturated with bitumen and brines, provide the most favourable environment for preservation of large extinct mammals. It is likely that during the Pleistocene winters, when thick ice and snow covered the tundra lake and swamp, zones of outflow of brines, oils, helium, and thermogenic gaseous hydrocarbons had a higher temperature, which could have resulted in melting and cracking of the ice cover and drowning of large mammals. The most favourable conditions for preservation of large, extinct mammals probably still exists in the vicinity of sampling probe sites Nos 21, 22, 23 and 36. Zones of dominance of microbial methane concentrations are less favourable sites for preservation of extinct mammals, because this methane was generated within recent swamps and also within recent descending meteoric waters which infiltrated into Pleistocene and Holocene sediments. Older Pleistocene microbial gases have already escaped to the atmosphere.

    Opis:
    Celem niniejszego artykułu było stwierdzenie, w jakim stopniu tkanki miękkie i muszle Anodonta anatina (L.) (szczeżuja pospolita) odzwierciedlają zmiany poziomów Cu, Zn, Pb, Co, Cd i Hg w wodzie powierzchniowej i osadach dennych (frakcja poniżej 0,20 mm) ujścia Odry. Materiał do badań laboratoryjnych został pobrany w latach 1999 i 2000 z obszaru ujścia Odry (19 stanowisk) oraz z jeziora Miedwie (jedno stanowisko). Na każdym stanowisku oznaczano koncentracje metali w wodzie powierzchniowej, osadach dennych (frakcja poniżej 0,20 mm) oraz w tkankach miękkich (całe ciało) i muszlach Anodonta anatina. Analizowano 20 próbek tkanek miękkich i 12 próbek muszli Anodonta anatina oraz po 20 próbek wody powierzchniowej i osadów dennych. Na każdym stanowisku analizowano próbki Anodonta anatina obejmujące co najmniej kilkanaście okazów o różnych rozmiarach (tzw. próbki uśrednione). Oznaczenia Cu, Zn, Pb, Co, Cd dokonano techniką ICP-AES, a Hg oznaczono techniką CV-AES. Przy zastosowaniu Anodonta anatina, jako organizmu wskaźnikowego, rejestruje się zmiany poziomów stężeń metali ciężkich w wodzie powierzchniowej na podstawie analizy tkanek miękkich i muszli (Cu i Zn), analizy muszli (Pb i Hg) oraz analizy tkanek (Hg). Z sześciu badanych metali nie kontroluje się tylko zmian Co. Z kolei zmiany koncentracji metali w osadach można kontrolować, wykorzystując tkanki miękkie i muszle (Zn i Hg), tylko tkanki (Cu, Pb i Cd) i tylko muszle (Co).
    The aim of the present article was the determination to what extent soft tissues and shells of the Anodonta anatina (Anodonta cygnea piscinalis NILSSON 1823; Anodonta piscinalis NILSSON 1823) reflect the changes Cu, Zn, Pb, Co, Cd and Hg in superficial water and bottom sediments (fraction below 0.20 mm) of the Odra River estuary. The material for laboratory investigations was taken in years 1999 and 2000 of the Odra River estuary (19 research points) and from Lake Miedwie (one research point). The concentrations of metals were marked at every research point in superficial water, bottom sediments and in soft tissues (whole body) and shells of the Anodonta anatina. 20 samples of soft tissues, 12 samples of the shells of the Anodonta anatina and 20 the samples of superficial water and bottom sediments were analysed. Samples of the Anodonta anatina (averaged samples) were analysed at every research point consisting more than ten specimens of various sizes. Quantitative determination Cu, Zn, Pb, Co, Cd was executed with the technique ICP-AES and Hg was marked with the technique CV-AES. The changes of the levels of the concentrations of heavy metals in superficial water were correlated with the results of the analysis of soft tissues and shells (Cu and Zn), the analysis of shells (Pb and Hg) and the analysis of soft tissues (Hg). Only changes of the Co did not show appropriate correlation. The soft tissues and shells (Zn and Hg), only soft tissues (Cu, Pb and Co) and only shells (Co) can reflect the changes of concentration of metals in bottom sediments.
