AbstractPhysicochemical properties of soils have a significant impact on the growth and development of vegetation. In urban areas, because of increased human activity, changes occur in both grain-size composition as well as physical and chemical properties of soils. These soils are frequently saline and contaminated with heavy metals, which limit the development of vegetation and cause its necrosis. Elm is a commonly growing tree with low habitat requirements, whose population has been considerably reduced because of progressing Dutch elm disease. This study attempts to assess the relationship of dependency between physicochemical parameters of soils and health status of elms from the area of the City of Kielce. Two elms were selected for the study, that is, one alive tree being a natural monument and one necrotic tree. The soil analysis concerned physicochemical parameters such as size composition, reaction, salinity measured by means of proper electrolyte conductivity (PEC), acidity, organic carbon content, carbonates, nitrogen, and selected elements including heavy metals (Cu, Pb, Zn, Cd, Mn). The study indicates differentiation amongst the physicochemical parameters of the analysed soils. A characteristic feature of the soils being the habitat of the necrotic elm is that they have considerably higher salinity than those being the habitat of the alive elm. Increased levels of sodium and chlorides could negatively affect water transportation in vegetation what might have resulted, amongst others, in necrosis of the tree.

Purpose. The problem of environmental pollution by heavy metals is one of the most important problems of the present and the near future. The compounds of these elements are characterized by high toxicity, mobility and ability to bio-accumulation. The aim of the study was to establish the main regularities of trace elements of the national natural park (NNP), to determine the indicators of their mobility for assessment of state of environment.Scientific novelty. The article discusses the features of distributing of heavy metals in the components of landscapes of the territory of the national natural park for realization of control and settlement of his concentration in accordance with the set norms.Results. The analysis of the landscape-geochemical conditions of the territory of the national natural park “Nyzhniosulskyi” has been performed. Consistent patterns of heavy metals distribution in the modern soil of the territory of NNP “Nyzhniosulskyi” have been determined. The analysis of landscape-geochemical conditions of the territory indicates that they generally contribute to the migration of chemical elements with land runoff as well as their significant vertical redistribution. The differentiation of landscape-geochemical conditions causes the fixation and accumulation of a significant number of natural and man-made chemical elements on the landscape-geochemical barriers (mechanical, redox, acid-alkaline, sorption, sorption-gley). This prevents from intense pollution of the vast majority of landscape regions in the park by polluting substances migrating from agricultural lands, which is confirmed by the results of the analysis of pollution sources and volumes. It was shown, that processes of transformation and migration of heavy metals compounds in the soil profile are determined by physical and chemical properties of soils.The analysis of the content of heavy metals in the soils of NNP “Nyzhniosulskyi” has shown that , the distribution of heavy metals is uniformly dispersive, but the variations in the content of certain heavy metals can range from ± 7% to ± 25%-35%. The greatest bioaccumulation capacity is expressed in biogenic microelements – manganese and cuprum. The analysis of heavy metals content in the landscape regions of NNP “Nyzhniosulskyi” has confirmed its dependence on available sources of technogenic contamination as well as the high degree of compliance of the nature of heavy metals distribution to the general laws of these processes in the soils of the relevant types. Most heavy metals get into the Sulyn aquatorium mainly during spring flood with snow melt water. The excess of Cd2+, Cu2+ and Pb2+ in water has been noted in comparison with the current threshold level value regulations.According to the results of the landscape-geochemical analysis of the NNP “Nyzhniosulskyi”, it can be stated that the territory from the ecological point of view is poorly contaminated and can be used for the development of recreational activities in compliance with a number of requirements.Practical significance. The results of this study have been introduced into practice of the NNP “Nyzhniosulskyi” in organizing and conducting research work, for planning tourist and recreational activities, forming tourist routes, and organizing recreational infrastructure.

This paper deals with the problem of anthropogenic soil pollution of cities with oil production on the example of Novokuybyshevsk, Samara Region. To assess the modern ecological-geochemical state of soil cover in Novokuybyshevsk in August 2016 the field study was carried out and soil samples for laboratory analysis were selected. The study was carried out on 8 test areas, 7 of which were in different functional zones of the city, significantly differing in environmental conditions. The sample site was in a green area 10 km from the city. Soil samples were collected according to the methods generally accepted in soil science and Geochemistry. The quantitative content of oil products and heavy metals (Ni, Zn, Cu, Pb, Cd, Mn) in soil samples was determined in a specialized laboratory by certified procedures on the equipment, timely verified and calibrated. The data analysis revealed significant anthropogenic transformation of the soil cover in Novokuybyshevsk, which was enriched with petroleum and heavy metals. It also shaped the conditions that increased the migration of heavy metals in soils and their availability to biota. The soils of the city are characterized by relatively even distribution and high content of Zn and Cu. On the contrary, the Mn content is characterized by a rather low rate, which is especially evident for the soil sample area. The accumulation of Zn, Pb and petroleum products in the soils of the city is connected with the influence of the industrial zone. The motor component involves the contamination of soil by Ni, Zn, Si, Cd and petroleum products. No functional area in Novokuybyshevsk contains high levels of Pb concentrations, the content of which exceeded the MPC only in the industrial area. This fact can be associated with the ban of tetraethyl use in gasoline production in Russia in 2002. The obtained results can be used for environmental monitoring of the urban environment and predict changes of ecological-geochemical situation in Novokuybyshevsk in the future.

<p>Woody plants are able not only to absorb metals of anthropogenic origin, but also to deposit their significant quantities in wood, leaves, and thereby temporarily remove them from the cycle of substances of urban ecosystems. The paper compares the content of heavy metals – Cu, Zn, Pb, and Cd in the leaves of the bioindicator species <em>Pоpulus рyramidalis</em> Roz and their mobile forms in soils collected from 6 test locations from various functional zones of the Southern industrial district of the City of the Cherkassy. Soil-geochemical associations of Cu, Zn, Pb and Cd content in the investigated locations indicate that the main source of Zn, Cu is the emissions of of the Cherkassy thermal power plant, and Pb, Cd – of urban transport. According to the total accumulation in the leaves of <em>P. pyramidalis</em>. The heavy metals are located as follows: Pb&gt; Cd&gt; Cu&gt; Zn. It was established that the content of mobile forms of Cu, Zn, Pb, and Cd in the soils of the experimental sites was several times higher than background values, and the coefficient of biological accumulation in the leaves fluctuated in insignificant limits. According to the results of indicators of the accumulation coefficient, the leaves of <em>P. pyramidalis</em> have low bioavailability in Cu and Zn, and the availability of Pb and Cd approaches the average. The obtained data can be used for the creation and reconstruction of green plantings of urban transport highways, sanitary protection zones of industrial sites of enterprises, recreational areas, squares.</p>

The paper presents the results of the study on soil quality in Maykop using algae indication. The findings suggest soil contamination by heavy metals and oil products, and the beginning of destructive processes. The city center is recognized to be the most unfavorable ecological area of the city. There are no diatoms in soil cyanoalgological sinusiae ‒ a key indicator of oil contamination of soils. On the contrary, cyanobacteria prevail, which are resistant to soil contamination with oil products and heavy metals. One of the main environmental problems in Maykop is soil contamination with heavy metals and oil products. The main contributor to soil contamination is city transport and housing and public services. Pollutants enter soil through precipitation and leaf and branch shedding, deposit from the air, and are directly absorbed by moist soil. The results of algological studies suggest that destructive processes have begun in the soils in Maykop. This is evidenced by the composition of soil cyanoalgological sinusiae and by the population of main groups of microphototrophs. The most ecologically disadvantaged city district is «Central Market».

In general, coastal areas have the physical and chemical properties of lessfertile land with an extreme dry climate, so that only a few plants that can live,including Jatropha curcas L. To enhance fertility and improve soil physicalproperties, need the addition of organic fertilizer. Source of compost canbe derived from a variety of wastes, including household waste and landfill.Quality compost landfill taken from Piyungan, Yogyakarta, has a high content of organic C, pH neutral, low N concentration, with the ratio C/N is very high. But compost landfill has an obstacle in the form of heavy metal containing high Cu and Pb. To prevent accumulation heavy metals into plant tissue or clean up heavy metals from the soil it was attempted by phytoremediation using jatropha plantation and bio-fertilizer that contains bacteria Azotobacter sp and Pseudomonas sp.From the research results can be informed that: (1) The city compost and biological fertilizers, can increase soil fertility with increasing nutrient content in soil. (2) Biofertilizers could inhibit the accumulation of copper (Cu) and lead (Pb) into Jatropha curcas L., (3)Jatropha plant can be classified as phytoremediation plants, because it can absorption heavy metals into leaf tissue.Key words: landfill compost , bio fertilizer, jatropha plants, heavy metals

Abstract For the first time, a survey about agricultural land focusing on the partitioning of the Pb, Cd, and Zn to the rural part of Mitrovica in northern Kosovo was made. Kosovo’s Mitrovica is one of the main industrial sites in the former Yugoslavia and a world-class mining district in Europe. The process of obtaining metals dates since 1927. From this year until 2000, the technological process of acquisition/obtaining has been accompanied by environmental pollution by creating waste landfills. These landfills are located on the outskirts of the city of Mitrovica at a distance from 1 to 4 km. In this area high levels of heavy metals in air, water, and earth were noticed. Therefore, these metal residues have a particular impact on air, earth, water, and effects on plants, animals and humans health. This situation became alarming; therefore in 2000 the production process was discontinued. During the period from 2000 to the present day, there is noticed a change of nature. Residents of the area have begun to work on agricultural lands without realizing the potential risk coming up. Despite the stagnation of industrial production, environmental pollution continues even further, especially from the landfill generated by industrial wastes. Widespread and very visible contamination mainly from Pb, Zn, Cd were found on the ground, with the highest concentrations measured near the Zveçan smelter. A significant amount of Cd, Pb, and Zn in contaminated soils/ground was quite movable/changeable, suggesting that these elements may be readily available for plants and soil/ground organisms. The main objective of this work is to address this pollution and take measures for education and information.

In the article, the basic morphological features, physical and chemical properties of soils of Odesa, analyzed indicators nutrient content, humus pHN2O, soil particle size distribution. The composition of salts and absorbed bases in soils is established. The purpose of this study is to characterize the soil cover of Odesa City. 47 full-profile sections were laid in 9 key sections in the city area. Key areas are characterized by the different anthropogenic impact on the soil upper layer and intensity of its use. According to the result of the studies of soils in Odesa City, the following groups of soils are distinguished in the territory of the city: natural undisturbed soils, anthropogenically externally disturbed natural soils, anthropogenically deeply disturbed soils (urban-soils). For natural undisturbed and anthropogenically externally disturbed natural soils, heavy loamy and medium loam granulometric composition is characteristic in most cases. The upper horizons of the soils of the firth overspill have a lighter composition – from light loamy to sandy. The granulometric composition of urban soils is heavy loamy, during a tendency toward its alleviation due to the anthropogenic increase of the content of sand fractions and skeletal material. A characteristic feature of undisturbed soils of the Odesa City is fairly high variability in the nitrogen content of nitrification, mobile phosphorus and exchange potassium, and organic substance. The sum of the absorbed bases in natural undisturbed and anthropogenically externally disturbed natural soils, as in urban areas, is low. The ratio between calcium and magnesium ranges from 2:1 to 6:1. Automorphic soils are predominantly weakly solonetzic. Marsh soils are characterized by a certain increase in the proportion of sodium from the sum of the absorbed bases - up to 36.47 %. Natural humus soils are characterized by a lack of salinity. Meadow soils from the surface have a weak degree of chloride type of salinity, and an average and a strong degree of chloride type of salinity is noted down to the profile. Urban soils have a weak degree of chloride-sulfate salinization, associated with the use of mixtures against ice in winter. Marsh soils have a strong degree of soda-chloride type of salinity from the surface. Key words: Odesa, urban soils, anthropogenic transformation of urban soils.

The results of the research showed that hydromorphous soils prevail on the territories adjoined to waste heaps. Swampy meadow and sod soils were defined. During investigation of swampy meadow soils it was determined that the soil is humused at a considerable depth. The soils are saturated with the bases. According to granulometric texture it is sandy loam soils, but with depth go to the middle loamy soils. The analysis for labile forms of heavy metals showed that in these soils the content of investigated heavy metals does not exceed the maximum allowable concentrations, except for lead. The amount of humus in sod soils sharply decreases with depth, the reaction is close to neutral. This soil is of slightly heavier granulometric texture. The content of labile forms of heavy metals doesn’t exceed MACs, except for lead.
