    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:
    In this paper, the influence of metals (Cd, Pb, Cu, Co, Ni, Zn) on plants of spring barley (Hordeum vulgare L.) was investigated in polluted sod podzolic sandy loam on layered glacial sands and calcareous deep chernozem on loamy loess soils. We propose to highlight the metals’ phytotoxicity with help of the phyto maximum allowable concentration. The Phyto Maximum Allowable Concentration is a permissible level of metals for plants in polluted soil and represents the safe degree for plants in contaminated ecosystem. The phyto maximum allowable concentration gives the possibility to estimate and to forecast the danger of metals for plants as a biological object that plays a very important role in the life of ecosystem. This approach may be applied for another metals phytotoxicity assessment for other plants.

    Opis:
    Many researchers from around the world are looking for better and cheaper means of ozone production. One of the methods of increasing the efficiency of ozone production is the use of a rotating electrode presented in this paper. Experiments were carried out which showed that the most important parameters are the materials used in the electrodes and the condition of their surface. The metallographic investigations of the electrodes after continuous work for a month were made, which show how the raids layers are formed. As a result of working in a highly oxidizing environment, the electrode is oxidized in a process of chemical corrosion. It is obvious that the layer of corrosion products created during the work of the plasma reactor isolates the surface of the electrode, which reduces the intensity of the electric field, causing a decrease in the amount of plasma generated, which reduces the concentration of ozone during this process. The dynamics of the plasma generation process and the type of electrode material working in changing process conditions are the decisive factors influencing the concentration of ozone produced. The influence of the medium, which is the electrode material, depends mainly on its resistance to corrosion in the environment of dynamically changing conditions, e.g. electrode rotation, oxygen flow through the rotating electric field and the month-long working time of the plasma reactor.

    Opis:
    The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. These metals have been extensively studied and their effects on human health regularly reviewed by international bodies such as the WHO. Heavy metals have been used by humans for thousands of years. Although several adverse health effects of heavy metals have been known for a long time, exposure to heavy metals continues, and is even increasing in some parts of the world, in particular, in less developed countries. However, over the last 100 years, emissions have declined in most developed countries. Cadmium compounds, the exception, are currently mainly used in re-chargeable nickel-cadmium batteries. Cadmium emissions have increased dramatically during the 20th century, one reason being that cadmium-containing products are rarely re-cycled, but often dumped together with household waste. Cigarette smoking is a major source of cadmium exposure. In non-smokers, food is the most important source of cadmium exposure. Recent data indicate that adverse health effects of cadmium exposure may occur at lower exposure levels than previously anticipated, primarily in the form of kidney damage, but possibly also in bone effects and fractures. Many individuals in Europe already exceed the recommended exposure levels and the margin is very narrow for large groups. Therefore, measures should be taken to reduce cadmium exposure in the general population in order to minimize the risk of adverse health effects. The general population is primarily exposed to mercury via food, fish being a major source of methyl mercury exposure, as is dental amalgam. The general population, however, does not face a significant health risk from methyl mercury, although certain groups with high fish consumption may attain blood levels associated with a low risk of neurological damage to adults. Since there is a risk to the fetus in particular, pregnant women should avoid a high intake of certain fish, such as shark, swordfish and tuna; fish (such as pike, walleye and bass) taken from polluted fresh waters should especially be avoided. There has been a debate on the safety of dental amalgams and claims have been made that mercury from amalgam may cause a variety of diseases. However, there are no studies so far that have been able to show any associations between amalgam fillings and ill health. The general population is exposed to lead from air and food in roughly equal proportions. During the last century, lead emissions to ambient air caused considerable pollution, mainly due to lead emissions from petrol. Children are particularly susceptible to lead exposure due to high gastrointestinal uptake and the permeable blood-brain barrier. Blood levels in children should be reduced below the levels so far considered acceptable as recent data indicates that lead may hold neurotoxic effects at lower levels of exposure than previously anticipated. Although lead in petrol has dramatically decreased over the last decades, thereby reducing environmental exposure, phasing out any remaining uses of lead additives in motor fuels should be encouraged. The use of lead-based paints should also be abandoned, and lead should not be used in food containers. In particular, the public should be aware of glazed food containers, which may leach lead into food. Exposure to arsenic is mainly via intake of food and drinking water, food being the most important source in most populations. Long-term exposure to arsenic in drinking water is mainly related to increased risks of skin cancer, but also enhanced risk of some other cancers, as well as other skin lesions such as hyperkeratosis and pigmentation changes. Occupational exposure to arsenic, primarily by inhalation, is causally associated with lung cancer. Clear exposure-response relationships and high risks have been observed.

    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:
    In the shadow of discoveries of large deposits of mineral resources in Poland after World War II, intensive exploration works were carried out, but the results of this research did not bring such spectacular effects. Exploration of Zn-Pb deposits conducted in the vicinity of historic deposits of Tarnowskie Góry and Bytom led to documentation of the Zawiercie, Goluchowice and Marciszów deposits. With some successes, exploration works of metal ore deposits in Paleozoic igneous and metamorphic rocks of the NE margin of the Upper Silesian Coal Basin were carried out. In this area, the Myszków Mo-W-Cu mineral deposit was confirmed, representing the porphyry copper genetic type. Moreover, in the area of Mrzyglód, the promising mineralization zone was found, requiring further geological research. The exploration of uranium and rare earth element ores did not lead to documentation of the deposits, nevertheless they made it possible to recognize all geological structures in Poland in terms of the possibility of occurrence of ore deposit occurrence of these metals. The prospecting works for these goals was carried out with a relatively small scale and were limited of the Sudetes, where exploitation took place on a fairly large scale in the past (Zloty Stok, Radzimowice, Klecza-Radomice, Wądroże Wielkie). The gold concentration occurring in the Zechstein Kupferschiefer formation and the porphyry copper mineralisation in NE margin of the Upper Silesian Coal Basin were also studied. The PGI participated in the exploration of mineral resources in marine areas, where besides the hydrocarbon exploration in the Polish economic zone, research on the Baltic polymetallic nodules was carried out, and within the INTEROCEANMETAL consortium the raw material potential of the Clarion-Clipperton Zone in the Pacific was studied.

    Opis:
    City Recreational Parks (RP) exert important functions for inhabitants of great agglomerations. They create peculiar ecosystem subjected to high pressure of anthropogenic factors (ie, motorization, maintenance, dusts), which may be a source of heavy metal contamination. Four parks located within the city Poznan have been: RP Marcinkowski (RPM), RP Solacki (RPS), RP Wodziczko (RPW) and RP Piatkowo (RPP). The aim of the work was to apply different quantitative methods for assessing heavy metal contamination state of these parks and to outline the encountered difficulties in the choice of the appropriate method. On the basis of the assessment made by the IUNG suggestion [16], it appeared, that soils of all Recreational Parks may be considered as not contaminated by Pb, Cu and Zn. Cadmium was the main contaminant of RPM, RPS and RPW soils. The use of data representing the geochemical background [17], classifies soils of all parks as contaminated to polluted, even, whereas the evaluation made on the basis of mean heavy metal contents of Polish soils [18], stated that cadmium solely exceeded the reference value. Criteria reported in the Minister of Environment Directive [19] dealing with heavy metal thresholds seem to be less restrictive. The resulting assessment revealed that soils of investigated parks are free of any contamination.
    Rekreacyjne Parki (RP) miejskie spełniają ważne funkcje dla mieszkańców wielkich aglomeracji. Tworzą swoisty ekosystem, który jest poddany silnej presji czynników antropogenicznych (motoryzacja, prace pielęgnacyjne, pyły) mogących być źródłem zanieczyszczenia metali ciężkimi. Badaniami objęto cztery parki mieszczące się w mieście Poznań: RP Marcinkowskiego (RPM), RP Sołacki (RPS), RP Wodniczki (RPW) i RP Piątkowo (RPP). Celem pracy było zastosowanie różnych metod ilościowej oceny stanu zanieczyszczenia gleb tych parków metalami ciężkimi oraz wskazanie na trudności wyboru odpowiedniej metody. Z oceny przeprowadzonej metodą zaproponowaną przez IUNG [16] wynika, że gleby wszystkich parków są niezanieczyszczone Cu, Zn i Pb. Kadm był głównym czynnikiem zanieczyszczającym gleby RPM, RPS i RPW. Gdy zastosowano jako kryterium tło geochemiczne [17], gleby parków zaliczono do grup od zanieczyszczonych do skażonych, natomiast według oceny dokonanej w oparciu o średnie zawartości metali ciężkich dla gleb polskich [18], tylko zawartość kadmu znacznie przekraczała wartość referencyjną. Kryteria zamieszczone w Rozporządzeniu Ministra Środowiska [19] odnośnie progowych zawartości metali ciężkich wydają się być "mniej restrykcyjne". Ocena przeprowadzona w oparciu o te wartości progowe wykazała, że gleby badanych parków są wolne od zanieczyszczeń.

    Opis:
    The investigations were focused on determining the level of trace element pollution of soil and root vegetables cultivated for human consumption in the Miechowski county. The collected soils differed in view of their floatable particles, colloidal clay and organic matter content, as well as pH value. Differences in the total content of trace elements and the content of their soluble forms extracted with 0.1 mol • dm–3 HCl solution also occurred. The total content of trace elements in the analysed soils and their soluble forms were determined by soil reaction. Geometric mean of total heavy metals content in the studied soils was as follows: 55.08 mg Zn • kg–1, 8.08 mg Cu • kg–1, 10.05 mg Ni • kg–1, 19.85 mg Pb • kg–1 and 0.46 mg Cd • kg–1. The assessment of heavy metals content in the analysed soils was conducted according to the framework guidelines for agriculture elaborated by IUNG. In this respect 44 of analysed samples were classified as soils with natural heavy metals contents. The content of trace elements in cultivated root vegetables was determined by the species, analysed plant part and soil pH. The content of these elements was much higher in plant tops than in roots. For instance, if one assumes geometric mean of cadmium and lead content in parsley roots grown in soil with pH • 6.5 as 100, cadmium concentration in leaves was higher by 64 %, and lead content was higher by 36 %. On the basis of the obtained results, content of trace elements in vegetable roots was assessed assuming the critical levels of trace element in agricultural products stated by IUNG. Taking into consideration these criteria was stated that all samples of the vegetable roots fulfilled the requirements of usefulness for human consumption in respect of copper and nickel contents, and majority of them in respect of lead content. However, 7.6 % of samples did not fulfil these requirements because of excessive content of lead (> 1 mg • kg–1), 52.5 % of zinc (> 50 mg • kg–1), and as much as 81.6 % samples because of cadmium excess (> 0.15 mg • kg–1), despite their being cultivated in majority in soils with natural these metals content. Excessive content of copper and nickel was registered only in 1.3 % of tops samples, lead in 51.3 %, zinc in 79.7 %, and cadmium in 98.1 % of tops samples, in which 7.6 % of tops samples did not meet fodder requirements for zinc, and as much as 65.8 % for cadmium. Taking in to account all roots and tops samples, only 0.6 % of them did not meet criteria of usefulness for human consumption, because of copper and nickel excess, 29.4 % for lead, 66.1 % for zinc, and as much as 89.9 % of samples contained excessive amount of cadmium. Moreover, in 3.8 % of samples Zn content exceeded admissible values in fodder and in 32.9 % contained excessive amount of Cd.
    Badania dotyczyły określenia stopnia zanieczyszczenia gleb oraz warzyw korzeniowych uprawianych na cele konsumpcyjne pierwiastkami śladowymi na terenie powiatu miechowskiego. Zebrane gleby były zróżnicowane pod względem zawartości części spławialnych, iłu koloidalnego, materii organicznej, wartości pH, całkowitej zawartości pierwiastków śladowych oraz ich form rozpuszczalnych w roztworze 0,1 mol HCl • dm–3. O całkowitej zawartości pierwiastków śladowych, jak i ich formach rozpuszczalnych w badanych glebach decydował odczyn gleb. średnie geometryczne całkowite zawartości metali ciężkich w badanych glebach wynosi ły: 55,08 mgZn • kg–1, 8,08 mgCu • kg–1, 10,05 mgNi • kg–1, 19,05 mgPb • kg–1 i 0,46 mgCd • kg–1. Zanieczyszczenie badanych gleb metalami ciężkimi oceniono w oparciu o ramowe wytyczne dla rolnictwa opracowane przez IUNG. Pod tym względem 44 badane próbki glebowe zaliczono do gleb o naturalnej zawartości metali ciężkich. O zawartości pierwiastków śladowych w uprawianych warzywach korzeniowych decydował gatunek, analizowana część rośliny oraz pH gleby. Zawartość tych pierwiastków była znacznie większa w częściach nadziemnych niż w korzeniach. Przyjmując np. średnią geometryczną zawartość kadmu i ołowiu w korzeniach pietruszki wyrosłych na glebach o pHKCl • 6,5 za 100, zawartość kadmu w naci była większa o 64 %, a ołowiu o 36 %. Na podstawie uzyskanych wyników oceniono zawartości metali śladowych w warzywach korzeniowych, przyjmując ich poziomy krytyczne w płodach rolnych opracowane przez IUNG. Biorąc pod uwagę te kryteria stwierdzono, że wszystkie próbki korzeni spichrzowych badanych warzyw spełniały wymagania przydatności konsumpcyjnej dla ludzi pod względem zawartości miedzi i niklu, a większość pod względem zawartości ołowiu. Natomiast 7,6% próbek nie spełniało tych wymagań z powodu nadmiernej zawartości ołowiu (> 1 mg • kg–1 s.m.), 52,5% cynku (> 50 mg • kg–1 s.m.), a aż 81,6 % próbek z powodu nadmiaru kadmu (> 0,15 mg • kg–1 s.m.), pomimo że warzywa były w większości uprawiane na glebach o naturalnej zawartości tych metali. Nadmierne zawartości miedzi i niklu zanotowano tylko w 1,3 % próbek, ołowiu w 51,3 %, cynku w 79,7 %, a kadmu aż w 98,1 % próbek naci tych warzyw, w tym 7,6 % próbek nie spełniało wymagań paszowych pod względem zawartości cynku, a aż 65,8 % – kadmu. Z ogółu próbek korzeni i naci nie spełniało wymagań konsumpcyjnych z powodu nadmiernej zawartości miedzi i niklu tylko 0,6 % próbek, ołowiu 29,4 % próbek, cynku 66,1 %, a kadmu aż 89,9 % próbek, w tym w 3,8 % próbek wykazywało przekroczenia dopuszczalnych zawartości Zn i 32,9% Cd w paszach.
