The development of industry, agriculture, transport and urbanization has resulted in excessive emissions of heavy metals into the environment, which due to their bioaccumulative properties express negative effects on the environment and living organisms as a whole. In this work the presence of heavy metals in the soil samples of the urban area of Lukavac and Kalesija municipality and their effect on the health of the population were studied. Soil samples were collected in October 2017 at five locations in the urban area of Lukavac municipality and two urban locations in Kalesija municipality. Concentrations of chromium (Cr) copper (Cu), cobalt (Co), nickel (Ni), cadmium (Cd), lead (Pb), manganese (Mn), iron (Fe) and zinc (Zn) in the soil samples were determined. The results indicated that in some locations the concentration of heavy metals exceeded the maximum permissible concentration (MPC). MPC value for chromium was exceeded at four locations in the urban area of Lukavac, whereas MPC value for nickel and cadmium was exceeded at all locations. In Kalesija, MPC value was exceeded for chromium and nickel at one location, while cadmium MPC was exceeded at both locations. The negative impact of heavy metals on the health of the population is the cause of many malignant diseases. Statistical analysis of the number of patients with malignant diseases in the area of the Lukavac and Kalesija revealed significantly higher prevalence of malignant diseases of the lungs, breast, skin and cervix in the Lukavac (p<0,05) in comparisson to Kalesija municipality.

The presented study addresses the problems of development of small and medium towns in Russia. Aim. The study aims to examine a town as a socio-economic environment where its residents exist and as the fundamental factor for the development of society.Tasks. The authors identify key problems in the development of small and medium Russian towns, which interferes with the historical appearance and has a negative impact on the living environment.Methods. Problems in the development of small and medium towns in Russia are examined using theoretical methods: systematic approach, statistical analysis, social and philosophical analysis.Results. The study identifies the main negative effects of the existing model of development of small and medium Russian towns, such as destruction of their historical and cultural appearance, distortion of the overall architectural motif, increased load on communications, and congestion of the transport infrastructure.Conclusions. At the current stage, efficient development of small and medium towns in Russia is impossible within the framework of the existing infill development. This chaotic process cannot be stopped without a new conceptual approach and changes in the legislative and normative framework of urban development. The only factor that determines the boundaries of the existing approach to urban development is the lack of physical space for new buildings in urban areas. The authors formulate proposals that would help to solve the problems of development of small and medium towns in Russia.

Air quality monitoring in many urban areas is based on sophisticated and costly equipment to check for the respect of environmental quality standards, but capillary monitoring is often not feasible due to economic constraints. In such cases, the use of living organisms may be very useful to complement the sparse data obtained by physico-chemical measurements. In this study, the bioaccumulation of selected trace elements (Al, As, Cd, Ce, Cr, Cu, Fe, Ni, Pb, S, Sb, Zn) in lichen samples (Evernia prunastri) transplanted for three months at an urban area of Central Italy was investigated to assess the main environmental contaminants, their sources, and the fluxes of element depositions. The results pinpointed Cu and Sb as the main contaminants and suggested a common origin for these two elements from non-exhaust sources of vehicular traffic, such as brake abrasion. Most study sites were, however, found to be subjected to low or moderate environmental contamination, and the lowest contamination corresponded to the main green areas, confirming the important protective role of urban forests against air pollution. Ranges of estimated mean annual element deposition rates in the study area were similar or lower than those reported for other urban areas.

Background and Aim: The quality of food, especially animal-based food, is crucial for human health. However, the quality of milk and other animal products has become an acute cause for concern in Kazakhstan . Technogenic dispersion of heavy metals (HMs) causes adverse effects on living organisms and creates unfavorable conditions for the existence of humans, animals, and plants. The purpose of this study was to analyze the content of several HMs in samples of soil, horse feed (hay, mixed feed, and bran), mare's milk, and manure to assess bioaccumulation and possible adverse effects on the bodies of horses. An additional purpose was to identify areas with acceptable conditions for obtaining environmentally safe horse breeding products in the agricultural zones of the Almaty region, Kazakhstan. Materials and Methods: Samples were obtained from two farms in the Almaty region in 2020 (spring, summer, and autumn). In total, 72 soil samples were analyzed, which were taken from the upper humus horizon to the depth of the arable layer. Eighty-six samples were taken from the feed of horses. Green feed was represented by perennial and annual grasses (alsike clover, Medicago sativa, sweet yellow clover, as well as pea and oat mix). Barley and wheat bran stored in the warehouses of the farm were sampled for the research as feed supplements. The mixed feed comprised components such as maize and sunflower. In addition, 46 samples of mare's milk and 28 samples of horse manure were collected. The HM analysis was performed in the laboratory of the Kazakh-Japanese Innovation Center. The residual amounts of HMs were determined using an absorption spectrometer with a voltammetric analyzer. The content of cadmium (Cd), lead (Pb), mercury (Hg), and arsenic (As) in all the studied samples of soil, feed, mare's milk, and manure did not exceed the threshold limit values (TLVs), suggesting that the intake of these toxic elements into the human body with food was low. Results: The average Cd concentration was in the range of 0.29-0.31 mg/kg in soil samples and in the range of 0.20-0.27 mg/kg in feed samples. In milk, the Cd concentration varied from 0.01 to 0.02 mg/L and was lower in summer and higher in fall. The total average Cd content in horse manure was 0.1844 mg/kg. The concentration of Pb in soil samples ranged from 1.09 to 1.30 mg/kg with the lowest value in spring and the highest in fall. In the feed, the concentration of Pb varied from 0.14 to 0.76 mg/kg and in milk from 0.03 to 0.15 mg/L. The average concentrations of Hg and As in soil samples averaged 0.022 and 0.019 mg/kg, respectively, and were within the TLVs. Conclusion: In the study areas, the calculated transition rates in the soil–feed–milk–manure system revealed that the greatest transition of HMs was observed for Pb and Cd, and a smaller migration was observed for Hg and As. The tendency of accumulation of trace elements continued in the feed.

State Of The Environment

Due to the increasing negative impact of anthropogenic factors on the state of the environment in man-made regions, the possibility of using Artemisia austriaса Jacq. as an indicator of contamination of industrial areas by some heavy metals and transformation of plant communities under the influence of human activities is being considered. In order to achieve the objective of the study, the content of heavy metals (Ti, Mn, Cr, Fe, Ni, Cu, Zn, Pb, Sr); in plant metals (A. austriaса) and soil samples selected in the suburbs of Pavlodar and Aksu (Pavlodar region, Kazakhstan) is analyzed at different distances from existing industrial enterprises. Geobotanic studies have also been carried out (using classical methods). A. austriaca, being a digressive-active species, under human-induced conditions often becomes a dominant or subdominant in plant communities (in regions where it has historically been represented in little abundance). Therefore, its capacity to accumulate some heavy metals (according to our research results – Zn and Cr) can be used (taking into account the distance from the source of emissions, age of plants, features of nanorelief and weather conditions) to determine the presence of contamination of industrial (or adjacent) areas, especially in areas of operation of metallurgical enterprises.

Recently, air pollution is a universal problematic concern which adversely affects global warming and more importantly human body systems. This chapter focuses on the importance of air quality, and indicates the negative effects of emissions originated from both municipal and industrial wastewaters to atmosphere. More importantly, the improvements in wastewater treatment plants to eliminate the crisis of emissions on environment and human health is also clarified. Urbanization and distribution of industrials in urban areas influence the air pollution via releasing pollutants and contaminants to environment. The pollutant emissions from wastewaters are volatile organic compounds, Greenhouse gases and other inorganic pollutants (heavy metals) which are causes to many reactions through atmosphere, then products detriment whole environment and living organisms including human. Moreover, contaminants are also released into air from influents of municipal wastewaters and they are considered as the main resources of most threatened infections in human and other animals. As conclusion, because of the persistently development urbanization and industrialization as the wastewater pollutant sources, the environmental technology regarding wastewater treatments must depend on prevention of emissions to air before thinking on cost and good quality effluents.

Mycotoxins are a wide group of compounds that often occur in food and feeds. These toxins negatively affect living organisms and may pose a risk for consumers’ health. Fish seem to be a particularly vulnerable group because negative effects can be observed at low levels of contamination, much lower than those considered harmful for other farmed animals. Mycotoxins may disturb cellular homeostasis by their influence on cells’ metabolism, causing DNA damage and organ lesions. Moreover, they are capable of immunomodulation, which may increase the occurrence of fish diseases caused by bacteria and other pathogens. Furthermore, these substances often have a negative impact on the growth rate of fish, which may cause economic losses to farmers. Although mycotoxins are commonly found in feeds, their ability to bioaccumulate in fish seems to be marginal. Therefore, according to the available data, fish may not be considered as the main source of mycotoxins for humans. Since there are no legal limits on the amount of mycotoxins present in fish feeds, it is necessary to constantly monitor the levels of mycotoxins in fish feeds and to investigate the influence of these substances on fish health..

Technogenic factors that have a negative effect on the environment and humans are analyzed. The integrated effect of negative impact on the environment aggravated by the number of factors is revealed. These factors include the following: gorges, river valleys and mountain landscapes. From the previously conducted studies it was concluded that the main source of negative effects on living organisms is the mineralized dust. The actual task of the study is determined, which consists in detailing the mechanisms and methods of the mineralized dust formation for improving the methods of minimizing its formation. Using the example of an open pit development of a dolomite deposit the relationship is established between the indicators of atmospheric dusting by the products of rock technological crushing and grinding. Dependence is established related to the dust emission intensity on the air flow velocity and dust concentration. It is proved that all the dust-like products formed as the result of mining and processing of the mineral raw materials have dimensions that allow them to move with the help of air masses. The results of the experiments on solving the problem of reducing dust by minimizing the output of mobile dust classes are presented (studies of the granulometric composition of rocks of various types with differentiation by type of the dust source, the mechanism of pollution using trapping screens and the development of directions for minimizing dusting of the atmosphere of the quarry and the surrounding area). The measures to reduce dust formation are proposed. The model for assessing the potential of environmental pollution by gas and dust products is developed. The proposed measures and the developed model will allow to minimize the effect of mining production on the environment of the region and the health of the workers of the mining enterprise and the residents of the region. The results obtained may be in demand when improving existing and developing new methods for improving occupational safety in the mining industry.

The paper presents data on the content of gross and mobile forms of zinc, cadmium, lead and copper in the soils of Chita and its surroundings. The paper contains a comparative analysis of the accumulation (Kn) and movement (KP) coefficients of these microelements in organs ( Potentilla tanacetifolia Willd. ex Schlecht.), relative to their gross content and mobile forms in soils. The authors have revealed that soil samples of the studied sites contain unequal gross amount of heavy metals. In some points (6 and 3) the content of cadmium and zinc exceeded the Mac, that is why such soils have been attributed to heavily polluted. The index of biological activity on mobile forms of heavy metals in all sites significantly exceeded the same index on gross forms. It was found that Potentilla tanacetifolia are accumulators of heavy metal ions. Aboveground bodies accumulate and absorb cadmium and copper especially intensively, thus the content of mobile forms of these metals in the soil is insignificant. Excessive adsorption of trace elements in the phytomass of plants can be connected with surface contamination. According to the content of zinc and lead, the accumulation values in the organs of P. tanacetifolia were characterized by small coefficient values, against the background of their high concentration in the soil.

Toxic Heavy Metals

Toxic heavy metals contaminating soil get accumulated by plants, cause degradation of plant communities, and eventually penetrate human bodies with food. Therefore, it is urgent to investigate the content of heavy metal in soils in urban areas. The aim of this study was to investigate the concentration of Cu, Fe, Mn, Pb and Cd in soils of Tyumen. Top soil was sampled at the semi-clean control site near a highway, and at sites near metallurgical, motor-building, oil-refining and battery-manufacturing facilities in Tyumen, Russia. The concentration of active and acid-soluble forms of heavy metals was determined by atomic-absorption spectrophotometry. All the soil samples from urban areas were polluted with Fe. The samples collected near the battery manufactory and the metallurgical plant were contaminated with Pb and Zn, respectively, with maximum allowable concentration exceeded. The Cu, Mn and Zn content in most soil samples was higher than that in the control sample. The Cd content in all samples was at the lower limit of detection. The average percentages of active forms of Mn and Zn in soils were the highest among all the studied metals. The most intense accumulation of all heavy metals was observed near the battery manufactory and the metallurgical plant. The obtained results can be useful for environmental monitoring in Tyumen.
