    Opis:
    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.

    Opis:
    In this paper, the degree of contamination of water was determined from anthropogenic reservoirs, located in the area of former coal mine Rozbark in Bytom. The physicochemical analysis of water indicated a high degree of anthropopression. In all analyzed reservoirs, permissible concentrations of chlorides and sulphates were exceeded. In the majority of them, the values of electrical conductivity and total suspended solids were also exceeded. In order to determine the transformation of surface water contamination, there was a comparison of archival data of water quality and laboratory tests performed after five years. Comparative analysis shows that in the last five years, there has been no improvement in the quality of the analyzed surface waters. In fact deterioration of the quality was noticeable.

    Opis:
    Magnetic susceptibility measurements remain one of the most reliable methods used to investigate the pollution of both surface and subsurface soil from metallic anthropogenic sources. Most of the geological rocks within the study area increase the susceptibility of the soil; however, knowing the natural background susceptibility of the parent rocks will give an idea of the anthropogenic influence on the susceptibility of the soil. This study was carried out in Kogi State, North Central Nigeria, with the aim of determining the depth of the boundary between the anthropogenic influences on soil magnetic susceptibility from those of a lithogenic origin. Magnetic susceptibility measurements were carried out on 1,760 soil samples, collected from 220 soil profiles at a depth of 80.0 cm and at intervals of 10.0 cm. From the spatial distribution of magnetic susceptibility maps at different depths, the boundary between the basement complex and the sedimentary basin was clearly demarcated. The result further shows the highest magnetic susceptibility values of 350–650 × 10−5 SI, which dominates the surface soil to a depth of 40.0 cm. At the depth of 40–50 cm, the result indicates the combination of a natural anthropogenic influence on soil magnetic susceptibility with an average of 250 × 10−5 SI. Furthermore, no evidence of layering along the depth sections was observed, suggesting that the soil profiles indicate areas mainly covered by anthropogenically influenced susceptibility, which were localized and restricted to commercial places within the state. This study reveals that the average depth of soil affected by anthropogenic pollutants is between 40–50 cm in commercial places and 20–30 cm in other places with less commercial activities.

    Opis:
    The chemical composition of the Quaternary aquifer in Old Krakow was studied. Thirty water samples were collected from wells in the years 2002, 2009 and 2012. The water chemistry of groundwater in Old Krakow is associated mainly with anthropogenic impact. The water samples represent manly five-ion type: Ca-Na-Cl-HCO3-SO4, Ca-Na-Cl-SO4-HCO3 and Ca-Na-HCO3-SO4-Cl, the multi-ion water type is typical for polluted water. The results of groundwater studies in Krakow between 2002 and 2012 showed that the chemical composition of water is being constantly affected by ancient human activities. The predominance of chloride and nitrate ions can be connected with a large number of the contamination sources. The main sources of contamination are accumulations of the anthropogenic soils and the cultural deposits containing organic, communal waste and sewage which were gathered in the oldest parts of Krakow.

    Opis:
    The objects of the study were grasslands situated along the watercourse that collect matter directly from surface runoff from the surrounding fields and ditches. Therefore, the chemical composition of the bottom sediments can be varied. The aim of the study was to determine the content of anthropogenic fractions of selected heavy metals in meadow soils where the material from the watercourse maintenance was stored. Soil samples were collected along the banks of the Witonia “A” Channel (soil with sediment), and 30 meters from the watercourse (soil without sediment). The pH of soils without sediment was in the range 6.2–6.6, whereas the soil with sediment had a pH ≥ 7.0. The content of organic matter was 5.7–31.5%. The concentration of anthropogenic fractions of elements was determined by atomic absorption spectrometry after extraction with a (1 + 4) HCl solution. The anthropogenic enrichment coefficients (AEC) calculated in relation to the geochemical background level, were within the range: 0.9–2.8 for Zn, 1.2–3.5 for Cu, 0.7–3.1 for Pb, 1.0–2.8 for Ni and 0.3–0.9 for Cd. The AEC values for lead, copper, cadmium and nickel were usually higher in samples without sediment. A significant correlation between the metal and organic content ( R2 = 0.7–0.9) was found. On two sites, the level of heavy metals under investigation shows a significant local influence from anthropogenic pressure.

    Opis:
    Changes in the magnetic susceptibility of topsoil, especially in urban areas, are greatly affected by the deposition of anthropogenic metallic dust arising from industrial activities, the burning of fossil fuels, car wear, and tyre abrasion. In this study, magnetic susceptibility measurements were carried out in vertical soil profiles of 30.0 cm depth from the surface at 10.0 cm intervals in about 431 locations within the Abuja metropolis with a view to investigate the penetration ability of magnetic pollutants in the ground. From the obtained data, 3-D surface contour maps were plotted for different depths. The results show a magnetic susceptibility decrease from the surface down the ground to the depth of 30.0cm; most of the recorded susceptibilities were of an anthropogenic origin rather than pedogenic activities. This indicates that the anthropogenic dust depositions are mostly a surface phenomenon and may therefore not pose a risk to groundwater aquifers and near surface wells.

    Opis:
    Important information about pre-Columbian Amazonian settlement and economy provide Amazonian Dark Earths (ADE), black or brown soils characterized by the presence of charcoal in high concentrations, with highly elevated nutrients and organic matter and higher pH level. Usually ADE are related to large concentrations of ceramics, stone artifacts and animal remains. The main factor for the initiation of ADE formation was the long-lasted, fully sedentary pre-Columbian settlement. Its size and a form can be correlated with traces of historical human habitation. Thus, these sites can reflect the social organization of a specific group. Therefore, ADE studies can bring much valuable information concerning pre-Columbian settlement in Amazonia.
