Research conducted in many research centers all over the world indicate health threats resulting from the presence of lead in the blood gradually decreases to the permissible amount. Lead accumulation in a living organism results in adverse changes in different body systems, symptoms of which include various behavioral changes. They can be reflected in grades obtained by the child at school. The aim of this paper was to establish whether the blood lead level diversify the boys in the respect of their school performance during consecutive years of primary education. The amount of lead in blood of 94 boys at the age of 10 has been measured; subsequently, the group of subjects was divided into two subgroups; the first one (termed in this paper „L”) comprised students whose Pb-B level was lower than 6 μg/dl (4,846 μg/dl on average) and the second one (termed „H”) comprised boys whose blood level exceeded 6 μg/dl (9,256 μg/dl on average). Academic performance in the arts, scientific subjects, geography and natural science in respective groups was assessed. Said procedure was replicated in respective subgroups after a year when the subjects were 11 years old. It was ascertained that the academic performance of the boys with higher blood lead levels deteriorated in scientific subjects and tended to worsen also in other school subject groups. Performance of the students whose blood lead level was lower in the initial examination remained unchanged or improved.

Badania podejmowane w wielu ośrodkach naukowych na całym świecie, wskazujące na zagrożenia zdrowotne wynikające z obecności ołowiu we krwi, zaowocowały stopniowym obniżeniem dopuszczalnej zawartości tego metalu ciężkiego w organizmie. Konsekwencją jego kumulacji są bowiem niekorzystne zmiany obserwowane w układach wewnętrznych, których jednym z przejawów są m.in. różnego rodzaju zmiany behawioralne. Mogą one przekładać się na oceny uzyskiwane przez dziecko w szkole. Celem niniejszej pracy było określenie czy poziom ołowiu we krwi różnicuje chłopców pod kątem ich osiągnięć szkolnych w kolejnych latach kształcenia w szkole podstawowej. Wykonano pomiar zawartości ołowiu we krwi 94 chłopców 10-letnich, a następnie całą grupę badanych podzielono na dwie podgrupy; pierwszą (zwana umownie „N”), w której znaleźli się uczniowie, których poziom Pb-B był mniejszy niż 6 μg/dl (średnio 4,84 μg/dl) i drugą (W) o zawartości ołowiu we krwi przekraczającej ten poziom (średnio 9,25 􀀀g/dl). Wgrupach tych oceniono osiągnięcia w nauce z przedmiotów humanistycznych, ścisłych oraz geograficzno-przyrodniczych. Procedurę tę w wyodrębnionych podgrupach powtórzono w kolejnym roku, a więc wśród 11-latków, Wśród chłopców o wyższej zawartości ołowiu we krwi stwierdzono istotne obniżenie się wyników w nauce przedmiotów ścisłych oraz tendencję do obniżania się ocen z pozostałych grup przedmiotów. Uczniowie, których poziom ołowiu we krwi był niższy w badaniu wyjściowym utrzymali lub podnieśli poziom swoich osiągnięć szkolnych.

In the present study, laser-induced breakdown spectroscopy (LIBS) has been applied for the determination of chromium and cadmium contents in wastewater of different canneries surrounding by leather factories. The plasma was generated with a Q-switched Nd:YAG laser having a fundamental wavelength of 1064 nm and delivers maximum pulse energy of 180 mJ. Experimental conditions were optimized to improve the sensitivity and to get a reasonable signal from the generated plasma. The results show that the concentration of chromium and cadmium are varying in different samples depending on the incoming flow of the wastewater from factories. The results from LIBS and standard analytical technique called flame atomic absorption spectroscopy (FAAS) were compared and found in good agreement within the experimental uncertainties.

In Ukraine, the tourism and recreation industry is widespread. These are mostly resort complexes with health boarding houses, hotels and restaurants. However, in Ukraine, the issue of solid household waste processing and active landfills, located near recreation facilities, is practically not addressed. Undoubtedly, this situation has a negative effect on the processes of recovery, because, as is known, landfills are depositing dangerous substances and compounds, which, due to geochemical flows, get into all components of the environment, which seem to be clean. The aim of this investigation is to determine the heavy metals content in the vegetation of a landfill near a places for recreation. The object of present research is the analysis of heavy metals content in the roots of trees on the Bronytsya landfill, located within the tourist and recreational complex of the Lviv region of Ukraine. It was established that tree roots are contaminated with Pb components and partially with Cd and Co components. Among the toxic chemicals, we can highlight the presence of Pb with a significant difference on the eastern side of the landfill in samples of Acer negundo L. (4 times higher than the MAC) and Populus nigra L. (7.1 times higher than the MAC), on the southern side – Fagus sylvatica L (1.1 times higher than the MAC) and Malus sylvestris Mill. (7 times higher than the MAC), on the west side – Salix cinerea L. (2.5 times higher than the MAC) and Carpinus betulus L. (6 times higher than the MAC), on the northern side of the landfill – Malus sylvestris Mill (2.5 times higher than the MAC) and Prunus spinosa L. (3 times higher than the MAC) and in the central part – Populus nigra L. (1.5 times higher than the MAC) and Salix alba L. (2 times higher than the MAC) in accordance with other samples on the investigated object. Cd exceeds the allowable concentration from the south side in Fagus sylvatica L. (1 times higher than the MAC) and Malus sylvestris Mill. (2 times higher than the MAC), from the west side in the root of Carpinus betulus L. (1 times higher than the MAC), from the center of the Salix alba L. (8 times higher than the MAC), from the south side of Malus sylvestris Mill. (11 times higher than the MAC), and on the eastern side Acer negundo L. (4 times higher than the MAC) and Populus nigra L. (8 times higher than the MAC). The content of Co was higher in the roots of trees from the west side of Salix cinerea L. (1 times higher than the MAC), from the west side of Carpinus betulus L. (1.7 times higher than the MAC), from the south side – Malus sylvestris Mill. (2 times higher than the MAC), and on the eastern side – Populus nigra L. (2 times higher than the MAC). An excess of Cu content was recorded on the western side of the landfill in the root of Carpinus betulus L. (1 times higher than the MAC). The determination of the chemical content in the roots of trees is important because it is possible to define the pollution rate of the environment in the health resort regions.

The article presents the results of the research from several years of exploitation of the vermiculture plots located in the municipal wastewater treatment plant in Zambrów. It is the only facility in Poland where the vermicompost from municipal sewage sludge has been produced continuously since 2004 (for 16 years). The results of tests of ready-made vermicomposts conducted regularly twice a year (32 tests) were subjected to a simple statistical analysis. The vermicompost analyses of heavy metals, biogenic compounds, organic matter and selected macroelements were compared with the requirements for mineral-organic fertilizers. In terms of the heavy metals content, the highest total content was observed in the first year of plots exploitation, i.e. in 2004, when it amounted to over 1200 mg-1 kg DM. The lowest sum content of heavy metals in vermicomposts, amounting to 398 mg-1 kg DM, was recorded in 2017. The median total content of heavy metals from all observations was 821 mg-1 kg DM. During the whole research period, the content of nutrients in vermicomposts was high, for nitrogen it ranged from 9.8 g-1 kg DM to 31.1 g-1 kg DM (median 14.3 g-1 kg DM), whereas for phosphorus it ranged from 2.1 g-1 kg DM to 14.5 g-1 kg DM (median 5.5 g-1 kg DM). The content of organic matter in the whole several-year study period was high and ranged from 21.3% DM to 59.0% DM (median 33.1% DM). The conducted research confirmed that the use of California earthworm in the process of municipal sewage sludge vermicomposting results in its good mineralization and humification, and the final product (vermicompost) may be a valuable mineral-organic fertilizer.

The basic physicochemical properties such as: dry mass, pH, pseudo-total content of cadmium, lead and copper, were determined in the fresh bottom ash samples from a municipal waste incineration plant. In order to study fractional composition of the investigated heavy metals, the BCR method was used (F1 – acid soluble and exchangeable fraction, F2 – reducible fraction, F3 – oxidizable fraction, F4 – residual fraction). The average percentage of cadmium in particular fractions was as follows: F1 (37.5%) > F4 (27.2%) > F2 (25.3%) > F3 (10.0%), for lead: F4 (36.5%) > F2(27.2%) > F3(23.4%) > F1(12.9%), and in the case of copper F4(66.3%) > F3(22.1%) > F2(7.4%) > F1(4.2%). Among the studied metals, in mobile pool (F1-F3) the highest amount of cadmium was noted (72.8%); for lead it was 63.5%, and for copper 33.7% of the pseudo-total content.

The paper presents the results of research on the use of sewage sludge from the municipal sewage treatment plant in Białystok for fertilization of urban lawns. To fertilize the ground two types of deposits were used: stabilized sludge after the dewatering process in the press and granular sludge after drying in the sludge dryer. Two doses of sludge were used – 5 and 10 kg/m2. Effective microorganisms (EM) were added to the test plots. Both doses of the applied sewage sludge contributed significantly to the growth of grass biomass. Aboveground biomass of the plants was significantly correlated with the concentration of Cd, Cu, Pb and Zn in the surface layer of the soil. The addition of EM to soil containing the dewatered sludge from the press reduced significantly the content of heavy metals in the soil, as opposed to the sludge in a form of granules with addition of EM, which contributed to the increase of their concentration in the soil.

Concentrations of several heavy metals in soil, water and grape samples (variety Plovdina) collected at five locations at different distances from the road in Southeast Serbia were determined using the Flame Atomic Absorption Spectrophotometry. There was a decrease in analyzed samples with an increase in distance from the road. A complete absence of several examined, very harmful heavy metals (Mn, Ni, and Cd) in all analyzed samples was found. The analysis of grape samples proved the presence of iron, zinc and copper in concentration ranges 3.3-19.8, 0.31-0.63, and 3.4-13.6 μg g-1, respectively. The content of heavy metals in soil, water and grapes were below allowable limits. Correlation analysis showed a significant relationship between the concentrations of metals in soil and grape samples.

Glasshouse experiments were carried out in Wagner pots containing 6 kg of soil. The amounts were compared of Zn, Pb and Cd taken up by the crop of spring wheat from contamination introduced into the soil or upon leaves. The heavy metals were labelled with the radioactive isotopes 65Zn, 210Pb and 115Cd. The experiment was performed as a series of independent analyses in four replications. The dynamics of the labelled heavy metals translocation from contaminations sprayed on the upper or bottom side of the flag leaf was also tested. The highest concentration of 65Zn was found in the straw and grain of wheat. Much higher amounts of the metals appeared to have been taken up by the plants from leaf contamination than from the soil. The highest dynamics of translocation from leaves to other vegetative and generative organs of plants was that of zinc.

The results of the research studies concerning the binding of heavy metals (HMs) by quartz sand functionalized with amino silanes have been described. The studies have been carried out on soils sampled from the areas affected by emissions from Copper Smelter and Refinery. The research aims to increase the food safety in the areas of industrial impact. The presence of polyamine chain in the hybrid materials obtained enables a binding of heavy metals (nickel, copper, cobalt). The best results are observed for the hybrid material having four amine groups (four coordination centers) per molecule. For this material the highest content after two extraction cycles (pH 7.0 and 5.0) is observed for copper (98.2%), but for other ions (nickel, cobalt) it is at least 85% of the initial amount of components available for plants.

The sewage treatment facility of a paper mill at Konstancin-Jeziorna was opened to process industrial and domestic wastewater. After closure of that mill, the sewage treatment facility had to be rebuilt and modernized. Therefore, it was necessary to analyse the chemical and phase composition of the sediments from facultative lagoons used for biological treatment of wastewater. Eight samples of sediments were taken to identify a general phase composition by X-ray diffraction and ten to determine concentrations of selected main and trace elements with the use of ICP-AES and AMA methods.The analyses showed that the sediments consisted of over 90% of mineral fraction, mainly kaolinite, calcite, and quartz and also neomorphic smithsonite. They contained low quantities of Hg, Cd, Co and Mo, and elevated concentrations of Zn, Ba, Mn and Sr. Comparisons of the obtained mean values with admissible concentrations of metals, as defined by Regulation of the Minister of Environment of 9 September 2002, showed that the mean concentrations of As, Sn, Co, Mo and Ni (and also of Hg and Cr in the southern lagoon) met quality standards for soils in areas under protection (group A). Mean concentrations of Pb (both lagoons), Ba, Cu, Cd (northern lagoon) as well as Cr and Hg (southern lagoon) in sediments are higher. However, they still meet standards for areas usable for agricultural and other purposes (group B). The highest concentrations were recorded for Zn, Cd, Cu and Ba in samples from the southern lagoon. These continued to be lower than all the limits acceptable for industrial areas.

Corn cobs and bagasse are materials used for making activated carbon that are easy to find. Additionally, they are agricultural waste that cannot be consumed. This study aims to analyze the potential of activated carbon from agricultural waste, namely corn cobs and bagasse, in reducing the levels of chromium heavy metal, and to analyze the dose of activated carbon from agricultural waste which is effective in reducing the chromium levels in the batik waste. The method used was experimental with a completely randomized factorial design. The doses of activated carbon used were 0.5, 1.5, and 2.5 g. Meanwhile, the contact times used were 30, 60, 90, 120, and 150 minutes. The results showed that the initial chromium content was 0.144 mg•L-1, and after given treatment it decreased to below 0.024 mg•L-1. The activated carbon from corn cobs and bagasse was able to reduce the chromium levels with the most effective dose of 2.5 g•L-1 and a contact time of 120 minutes. Meanwhile, the water quality parameters showed temperature stability (23–25°C) during the experimental period, while the pH increased to 9–11.

The aim of the study was to investigate the content of trace elements in deposited particulate matter and to estimate the health risk to Kraków inhabitants, caused by the exposure to heavy metals in particulate matter deposition. The qualitative and quantitative assessments of selected heavy metals in deposited particulate matter have been carried out in the city of Kraków (Małopolska, southern Poland, 5 measuring points) for seven months, between February and September 2017. A comparative study was conducted at the same time in Małopolska (5 measuring points). The deposited particulate matter was collected gravitationally, using measurement plates covered with aluminum foil and paraffin jelly. The largest deposition of particulate matter was found in May and June. The highest amount of deposited particulate matter and metals present in it was determined in Kraków. The Hazard Quotient (HQ) evaluation for non-carcinogenic effect showed low risk for each metal. In the case of lead in particulate matter, the carcinogenic risk value did not reach 10−6 hence this risk is acceptable. The total carcinogenic risk for all routes of exposure to cadmium was higher, indicating the risk of cancer in children and adults, with children more exposed. However, the carcinogenic risk for cadmium was also acceptable. The study showed that the problem of poor air quality concerns not only the city of Kraków, but also the entire Małopolska region. Elevated metal concentrations in particulate matter indicate the need for monitoring it in the air.

Marbled crayfish are the typical invasive hydrobionts spreaded over the lot of world`s waterbodies and create the populations that can reproduce in the presence of only one triploid female, thereby the threat of biodiversity appears and increase the competition with local species. Due to the appearance of the marbled crayfish Procambarus virginalis (Lyko, 2017) in the open Ukrainian waterbodies, there is necessity to research it`s adaptation possibilities to the ecological factors to predict it`s possible spread and naturalization. The research aim was to determine the physiological and biochemical features of the adaptations of marbled crayfish as a new species inhabiting the aquatic ecosystems of Ukraine under the conditions of toxicological load on the aquatic ecosystem. The obtained research results indicate significant changes in individual cytological and biochemical indicators of marbled crayfish under the impact of heavy metal ions. A change in these parameters may indicate a rapid cellular response of the crustacean species to the toxic effect of heavy metals. These indicators can be used in the future in studying the adaptation of marbled crayfish in natural waterbodies.

The aim of the research was the evaluation of the potential contamination with heavy metals in Fluvisols, used as grasslands and arable soils of Vistula River floodplain in the area of the Chełmiński and Nadwiślański Complex of Landscape Parks. The indicators proposed by Håkanson allow to evaluate the potential ecological risk of the contamination with heavy metals associated with the accumulation of one metal or a combination of multiple metals. The mean total content of Cd, Pb, Ni Cu, Zn, Mn, as well as Fe in Fluvisols at the depth of 120–150 cm was assumed as the content of the local geochemical background and it was: 1.0 mg·kg-1, 22.8 mg·kg-1, 26.9 mg·kg-1, 1.4 mg·kg-1, 60.8 mg·kg-1, 591 mg·kg-1, and 17.6 g·kg-1, respectively. The values of the indicators such as contamination factor (CF), enrichment factor (EF) revealed higher levels of the accumulation of heavy metals in the soils of grasslands, which shows that the method of their use has a significant effect on the total metal content. Contamination with heavy metals in the surface layer of the investigated Fluvisols was found, and in terms of the content with cadmium a moderate and considerable potential ecological risk was reported. Due to the fact that no unfavourable effect of trace elements on the riverside environment was proved and that the floodplain areas are under agricultural use, to evaluate the contamination with metals, the limit values for the soils of agricultural land were assumed as stipulated in the Regulation of Minister of the Environment of September 9, 2002. According to that criterion, the soils studied do not qualify as contaminated with metals. Only in one of the soil sampling points the total content of zinc was higher than the one determined as the maximum for agricultural land soils, namely 350 mg·kg-1. A significantly positive correlation was noted between the content of C org and the total content of metals as well as very numerous interactions between metals. The results of cluster analysis confirm that the method of use determines the concentration of metals in the surface layer of the Fluvisols studied.

The results of the research studies concerning binding of heavy metals and arsenic (HM+As), occurring in soils affected by emissions from Głogów Copper Smelter and Refinery, by silane nanomaterial have been described. The content of heavy metals and arsenic was determined by AAS and the effectiveness of heavy metals and arsenic binding by 3-Aminopropyltrimethoxysilane was examined. The total leaching level of impurities in those fractions was 73.26% Cu, 74.7% – Pb, 79.5% Zn, 65.81% – Cd and 55.55% As. The studies demonstrated that the total binding of heavy metals and arsenic with nanomaterial in all fractions was about as follows: 20.5% Cu, 9.5% Pb, 7.1% Zn, 25.3% Cd and 10.89% As. The results presented how the safety of food can be cultivated around industrial area, as the currently used soil stabilization technique of HM by soil pH does not guarantee their stable blocking in a sorptive complex.
