Opis:
Different compounds including toxic heavy metals ions have been used in various industrial branches for ages. Therefore, these compounds are nowadays often identified in the natural environment. Plants usually function like indirect transporters through which heavy metals, in the form of ions, infiltrate from the environment into the human and animals’ food chains. The present paper studied the influence of urban agglomeration on the accumulation of certain heavy metals in tansy. The content of heavy metals ions (Cr, Ni, Cd and Pb) was marked in the tansy leaves. Depending on the location of sampling, large variations in the heavy metal content were observed in the plant material. The research results indicate that the heavy metal content of tansy is influenced by the close “neighborhood” of a well-developed urban agglomeration such as patrol stations and factories.

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:
Tansy (Tanacetum vulgare L.) grows in moderate area of the northern hemisphere, in Poland – its range covers the whole country. It appears on the farm wastelands, by roadsides, on enbankments, river banks, forest lips and in open spaces. The present paper has faced the challenge of defining the influence of the environmental conditions on the mineral composition of Tanacetum vulgare leaves. The plants were picked in the blooming period from May to September 2017 in 12 natural environments of their growth and at different contamination levels. The dried and minced plant material was submitted to chemical analyses of the bio elements content (K, P, Cu, Zn, Mo) of leaves. A great variety was observed when speaking in terms of particular elements content in dependence on the position. In all tests, significant quantities of K and P were found. The study results point at the very fact that the mineral composition of Tanacetum vulgare leaves is influenced by the environmental contamination, caused by the nearby "neighbourhood" of circulation areas of high traffic volume, factories or patrol stations.

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:
The vegetation of the Chernihiv city sands (natural and technogenic origin) has rather high syntaxonomic diversity (17 associations and 5 initial communities) and the ruderal phytocoenoses prevail. Natural phytocenoses are represented to a small extent (Cyperetum flavescentis Koch 1926, Dichostylidi–Helochloetum alopecuroidis (Timar 1950) Pietsch 1973, Artemisia scoparia–Dianthus borbasii community, Kochietum arenariae Fijalk 1978). Synanthropic psammophytes species communities that are more resistant to anthropogenic influence, are formed under urban conditions. The ecological range of vegetation of sandy alluvia varies from xerophytic phytocoenoses in mineral-poor sand (Kochietum arenariae) to the communities, which indicate waterlogged areas with increased mineralization of water and saline bottom sediments (Typhetum laxmannii Nedulcu 1968). Itispossibletoobserve the adventization and apophization of sand vegetation, one of the indicators of which is the rupture of coenotic connections between the species of the community. These phenomena indicate that the process of synanthropization of the vegetation cover of the city keeps intensifying, and first of all, occurs in places of newly formed technogenic ecotopes.

The mineralogical compositions of SIAP and local soils are very similar and quite typical. Dust sources were attributed to high emission sources (two large coal-fired power generation plants, i.e., "Wrocław and "Czechnica") and low emission sources (mostly small furnaces for home heating). A mullite phase was confirmed in the non-magnetic fraction of high emission dust. The δ18181818

In order to do so it is necessary for the state to introduce a new system of anthropogenic hazards monitoring, recognition and management of risks, aimed at their minimization. Implementation of the risk-oriented approach in its substance represents the reform of the united state system of public Security.

Secondary geodiversity (represented by anthropogenic landforms, which can be considered a significant part of geoheritage of certain area) can be seen as an important resource for geotourism and geoeducational activities within urban areas. Brno city (Czech Republic) is rich in these landforms as well as numerous urban areas. Some of them (especially old quarries and underground spaces) are already used for recreation, tourism and leisure or they serve as excursion localities for the university students, some of them are unique from the geoscience point of view and they have also certain added values (historical, archaeological or ecological). However, in some cases, their potential is not fully recognised. The article describes the main anthropogenic landforms within Brno city and analyses their suitability for geotourism and geoeducational activities.

Opis:
Environmental pollution has resulted in several health and physiological problems in both plants and animals. This has witnessed growing number of models for assessment purposes. Some of these provide useful information, and reduce large data for easier understanding by policy-makers. In the current study of pollution, we used data from four locations: Oil Market, Trans Amadi, Borrokiri and GRA in Port Harcourt and a control taken from Federal Land Resource Umuahia (FLRU). A total of 25 composite soil samples were analyzed for physicochemical parameters and heavy metals, by means of a 969 Unicam AAS model series. The data obtained were then subjected to index models. Results showed iron (Fe) to be most abundant metal, ranging from 10.44 to 19.54 mg/kg, then Ni (8.03 to 13.6mg/kg), Cd (3.96 to 5.41 mg/kg), Pb (1.36 to 7.64 mg/kg), Zn (0.09 to 7.24 mg/kg), Cu (0.16 to 0.32) and As (0.07 to 0.11 mg/kg). All metal concentrations were below permissible limits set by NESRA. Contamination factor (Cf) and Igeo revealed moderate to heavy contamination by Cd and Zn. Anthropogenicity revealed that increasing metals in the environment are largely from anthropogenic inputs. The Pollution Index revealed that soils were unpolluted (PLI < 1) with the heavy metals. Furthermore, the Sodium absorption ratio showed that the soils are less sodic and could be good soils for plant growth. All four sites showed a linear relationship between anthropogenicity and geoaccumulation indexes, and so both indexes furnish basically the same information However, pollution from these metals in the study area should be under routine check for possible pollution in the near future, as some metals showed elevated concentrations above background values.

The autors suggest description of the change of shear strength due to dynamic loading in terms of the Wz ratio. It shows a quantitative change of strength due to vibrations related to the initial value of strength. The functional relations have been established between the Wz ratio and frequency of the dynamic loading. The autors indicate that the tested soils respond more intensively to vibrations in the horizontal plane, as well as to distinct quantitative and qualitative changes in the soil microstructure.

The summary of the measurements of CO2 stable isotopic composition emitted from different anthropogenic sources in the Krakow region is presented. The sources are divided into three main groups . high emission (electric and heat power plants), low emission (coal and methane burning in the households) and car traffic (gasoline, diesel and LPG supplied engines equipped and not equipped with catalyst). Presented results include two measurement campaigns made in the years 1995 and 2000. The measurements revealed three well-defined groups with respect to carbon isotope composition (delta13CVPDB): .30.60 plus-minus sign 0.37 per mille (thousand) sign (car traffic) .23.82 plus-minus sign 0.10 per mille (thousand) sign (coal burning) and .51.8 plus-minus sign 1.1per mille (thousand) sign (methane burning). The oxygen isotope composition (delta18OVPDB-CO2) of CO2 varied in a broad range, from ca. .11per mille (thousand) sign to ca. .22 per mille (thousand) sign, the most negative values being observed for coal and methane burning and the most positive for cars equipped with a catalyst. No significant isotopic shift has been observed between two measurement campaigns.

Opis:
The stronghold in Grzybowo (Rabieżyce village) near Września is a remnant of medieval ring-fort. It is investigated to a considerably lower degree than similar objects from Greater Poland. The analysis of archival data shows that the stronghold is located on the edge of the flood plain of the Struga River formed by Holocene sediments, cutting into the moraine plateau. Analysis of sediments in the stronghold vicinity revealed interlayers of organic matter and sandy deposits rich in calcium carbonate with variable grain size composition, particularly west of the stronghold (i.e. in the valley floor). Moreover, radiocarbon data set showed a considerably older than Holocene age of the sediment. The analysis of the course of the contemporary river channel also allowed for stating hypotheses regarding a potentially different course of the former Struga River channel and its changes during the development of the stronghold. These assumptions were based on the analysis of the archaeological archival data, where field drawings suggest the existence of such a channel in the territory of the stronghold.

Opis:
The aim of this paper was to evaluate the influence of anthropogenic pollution on the water quality of the Ciemięga River, which flows through the Jastków commune, located in the Lublin Province in the South-Eastern Poland. The analyses of the river water were conducted in the years 2019–2020. Each year, the samples for physicochemical analyses were collected seasonally (in February, May, August and November) from the seven selected Ciemięga River sampling points found in the following localities: Ożarów, Moszenki, Sieprawice, Jastków, Snopków and Jakubowice Konińskie. In addition, 3 series of microbiological analysis were conducted in 2020. Electrolytic conductivity, total phosphorus, nitrate-nitrogen and sulfates constituted the physicochemical indicators of poor water quality in the river. Their average values exceeded the standards for the 2nd class of water quality. High concentration of these indicators, especially of the total phosphorus, could have been related to the influx of domestic wastewater from agricultural holdings, wastewater flows from agricultural areas as well as soil erosion and leaching. The levels of E. coli bacteria and fecal coliform allocated the Ciemięga River waters to the 4th class of water quality and could result from domestic wastewater flow to the river. In order to improve the water quality of the Ciemięga River, it is necessary to reduce or eliminate point and non-point sources of pollution by means of streamlining of the agricultural areas fertilization, regulating the water and wastewater management, regulating of the waste management, as well as the appropriate spatial policy and landscaping of the water catchment areas.

The paper aims at presentation of the effect of changes in the catchment area management on the value of water quality physicochemical indices along the length of the Iwoniczanka stream, which flows through Iwonicz-Zdrój, one of the oldest health resorts in Poland. Analyses of 14 water quality indices were conducted from November 2013 to May 2014 in five measurement points: two situated in the upper course of the stream – in forest areas, two located in the area of Iwonicz-Zdrój town, and one below the rural built-up area. On the basis of the conducted data analysis it was found that the mean values of pH, electrolytic conductivity, sulphates, calcium, total iron and manganese were increasing with the course of flowing water, as evidenced by the water enrichment in substances which had their sources in built-up areas. On average, the highest values of biogenic indices and chlorides but the lowest values of oxygen indices were registered immediately below the location of drain collector from the closed sewage treatment plant, which resulted in pollution of the analysed stream bed with the substances previously drained from the treatment plant. Water flowing through the forest areas had the maximum ecological potential in the built-up areas and due to phosphate concentrations it was classified to class II and then, due to self-purification, returned to the physicochemical parameters appropriate for class I water. The conducted hydro-chemical tests confirmed a significant negative effect of built-up areas on the quality of the flowing waters.
