.One of the most urgent and significant social problems of our time is the problem of maintaining the ecological stability. Important role in optimizing the environment play greenery. Being a biological filter, they perform environmental, environment protection, recreational and social functions. Qualitatively improving the environment, urban plantations experience the negative impact of certain environmental factors and therefore require careful treatment and proper protection. The results of a comprehensive evaluation of the forest park plantations located in the northern district of the city district of Voronezh. Study included determination of the species composition of plants, forming phytocoenosis, assessment of health status and forest pathology plantations, and the analysis of the spatial structure of the stand, the class definition of aesthetic and hygienic value of the site. Range of plants at the site of research is represented by 3 divisions, 4 classes, 21 orders, 24 families, 38 genera and 44 species. Distribution of plants according to life forms is as follows: tree - 12 species, shrubs - 8 species, vines - 2 species, herbaceous plants - 22 species, lichens - 1 species. On the territory of the forest park very valuable plants are revealed, which include Scots pine, quickbeam and Sorbus intermedia, silver birch, Norway maple. The territory of the forest park belongs to the closed type of spatial structure. The stand is formed by cultures of Scots pine at the age of 45 years. Plantation is characterized by impaired stability; plants have signs of disease, pests, abiotic and anthropogenic factors. Hygienic assessment of planting complies with Class 2, the aesthetic value of the object - average one. In order to preserve the forest park plantings and increase their resilience to environmental factors it is proposed to develop the project of reconstruction of the object, including the division of the forest park into functional zones, sanitary measures and for landscaping. Preservation of the park area is a prerequisite for comfortable living of population of Kominternovsky district of city district of Voronezh.

Recently, the number of published works devoted to the processes of synanthropization of fauna, is growing like an avalanche, which indicates the extreme urgency of this theme. In our view, the process of forming devices to coexist with human and the results of his life reflects the general tandency of the modern nature evolution. Urbanization is characteristic for such a specific group of animals like amphibians, the evidence of which are numerous literature data. Many researchers use this group to assess the bioindicative quality of the environment. For this aim a variety of indicators are used: from the cellular level of life of organization up to the species composition of the group in different territories. At the same time, the interpretation of the results is not always comparable for different areas and often have significantly different interpretations by experts. Urban environment, primarily due to the contamination is extremely aggressive to amphibians. As a consequence, the urban populations of amphibians may be a change in the demographic structure, affecting the reproductive ability of the population, the disappearance of the most sensitive species or individuals, resizing animals, the appearance of abnormalities in the development, etc. At the same time play an important amphibians in the ecosystems of cities, and some species in these conditions even feel relatively comfortable. Therefore, it is interesting to understand the mechanisms of self-sustaining populations of amphibians in urban environments. To assess the impact of natural and anthropogenic factors on the development of amphibian populations were used cognitive modeling using the program Vensim PLE. Cognitive map of the model for urban and suburban habitat conditions were the same. The differences concerned the strength of connections between individual factors (migration, fertility, pollution) and their orientation. In general, factors like pollution, parasites, predators had negative impact on the population, reducing its number. The birth rate, food and migration contributed to raising number of individuals. Some of the factors affected on the strength to of each other as well: the majority of the factors affected the structure of the population, had an influence on the fertility. Thanks to it the model reflects the additive effect of complex of factors on the subsequent status of the population. Proposed and analyzed four scenarios differing strength and duration of exposure. In the first scenario, a one-time contamination occurs and not subsequently repeated. The second and third scenario assumes half board contamination, 1 year (2 scenario) and two years (scenario 3). In the fourth scenario, the pollution affected the population of amphibians constantly. In accordance with the results of simulation, much weaker than the natural populations respond to pollution - have them as an intensive population growth and its disappearance at constant pollution is slow. Changes to other parameters of the model showed that this pollution is the decisive factor -only the constant action leads to a lethal outcome for the populations. All other components of the model have a corrective effect on the population dynamics, without changing its underlying trand. In urban areas due to the heavy impact of pollution maintaining the population is only possible thanks to the migration process – the constant replenishment of diminishing micropopulations of natural reserves. This confirms the assumption that the form of existence metapopulations lake frog in the city. In order to maintain the number of amphibians in urban areas at a high level it is necessary to maintain existing migration routes and the creation of new ones. Insular nature of the placement of suitable habitats in urban areas causes the metapopulation structure of the types of urbanists. Therefore, the process of urbanization is much easier for those species whicht are capable of migration in conditions of city. In the initial stages of settling the city micropopulationis formed by selective mortality of the most susceptible individuals to adverse effects. In future, maintaining the categories of individuals is provided mainly due to migration processes metapopulisation form of the species of existence is supported). It should be noted that the changes in the previous levels are always saved in future. In the case of reorganizations of individuals we of morphology can assume the existence of extremely adverse environmental conditions that threaten the extinction of the micropopulations.

SC Cuprom SA Bucharest Branch Baia Mare is known as one of the biggest copper factory from ores from Romania, but at the same time one of the biggest polluters from the recent history of the country. Placed in the Baia Mare basin, at the outskirts of the city, the plant generated, in the past, a significant negative impact over the environmental factors, especially over the air and soil. The monitoring of the environment factors in the period offunctioning and after closure revealed a high level of pollution of the emplacement. After ceasing of the activity, in 2009, the emplacement passed through a period of continuous degradation, successive demolitions of the buildings and minimum involving regarding the protection of the environmental factors and application of depollution processes. In this moment the platform of Cuprom Sa represents a tampon zone placed in the eastern part of Baia Mare, which stand in the path of development of the city in that direction due to the high level of degradation of the site, high level ofpollution and lack of capitalization measures.

National goals regarding sustainable development from the Swedish government were decisive in the planning process when the newly built city district Western Harbour was established in the city of Malmö, Sweden. A systems analysis was used as a tool for evaluating different collection and treatment systems. This type of analysis does not include more subjective factors such as acceptance of organic fertilisers based on human waste and user acceptance of collection schemes. These aspects, however, will often determine the success of a technical solution. When the system for collection and treatment of solid organic waste and wastewater was designed, both subjective and objective factors were considered. This meant that a centralised solution for wastewater treatment was selected. In order to facilitate a more sustainable solution for sludge management a treatment process with recovery of phosphorus will have to be introduced. Organic waste is sorted out and treated in an anaerobic digestion process. Source sorting of solid organic waste has been difficult to implement in Sweden due to inadequate sorting discipline. As a consequence two relatively new systems are tested in the area. A comprehensive evaluation will be carried out during a period of two years.

Introduction. The prevalence of bronchial asthma and other allergic diseases, in particular atopic dermatitis and allergic rhinitis, nowadays can be estimated by global population studies, such as the International Study of Asthma and Allergy in Childhood (ISAAC), and the Global Asthma Network (GAN). There are some difficulties in epidemiological surveillance, diagnosis, treatment and prevention of these nosologies in most of the countries, especially in developing countries with low availability of medical care. Thanks to the GAN program, therapeutic recommendations were made to reduce the global burden of allergic pathology. Purpose of the study. To study the prevalence of clinical symptoms of allergic diseases in children 13–14 years old in the city of Tyumen, as well as highlight the main risk factors that contribute to the disease development. Materials and methods. This cross-sectional study was carried out in 2019 as part of the Global Asthma Network (GAN) project among adolescents 13–14 years of age in the city of Tyumen. The respondents filled out standardized Russified questionnaires, which contained 48 questions concerning the symptoms of allergic diseases and environmental factors. According to the results of the analysis of 3007 questionnaires, it was found that asthma-like symptoms were ever observed in 19,2% of participants, current asthma-like symptoms were noted in 8,5% of respondents, 5,1% of adolescents had medical-verified bronchial asthma. The prevalence of lingering allergic rhinitis and current allergic rhinoconjunctivitis was 28,9% and 12,2% respectively, while only 5,4% of respondents had a verified diagnosis of allergic rhinitis. A quarter of the respondents had symptoms of atopic dermatitis at some point (25,6%), only 4,5% had symptoms of current atopic dermatitis, 3,8% had been diagnosed with atopic dermatitis. The negative impact of heavy freight traffic in the city of Tyumen, as well as the use of paracetamol, revealed the increase in the prevalence of allergic diseases. Conclusion. As a result of data analysis, it was found that the prevalence of current asthma-like symptoms, symptoms of atopic dermatitis and allergic rhinitis significantly exceed the numbers of official statistics. Often, adolescents with symptoms of an allergic disease do not have a correct diagnosis, which is confirmed by a low percentage of positive answers regarding the verification of the diagnosis by a doctor. Among children 13–14 years old in the city of Tyumen there is a high percentage of the prevalence of symptoms of allergic rhinitis, which is probably associated with climatic, geographical and environmental factors.

Urban forested areas play an important role in maintaining a high quality of life in an urbanized society. They are assigned the main function in smoothing out negative factors of production and creating a favorable environmental environment. The growth and development of woody plants in urban environments often differs significantly from natural conditions. This factor is particularly acute in the work of the assimilation apparatus. The study of the content of pigments (chlorophylls a, b and carotenoids) in the annual conifer of scots pine (Pinus sylvestris L.) was determined in extracts using spectrophotometric analysis. As a result of the study, experimental data were obtained on changes in the pigment system in the coniferous pine needles with an increase in the level of contamination. The analysis of photosynthetic features of scots pine (Pinus sylvestris L.) in the studied forest park zones in the city of Yelets with a complex index of atmospheric pollution at the level of "low", showed minor differences in the sum Keywords: SCOTS PINE, CHLOROPHYLLS, CAROTENOIDS, INDUSTRIAL POLLUTION, LIPETSK REGION

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.

Background: The infant and neonatal mortality rate in Depok City is still high, with low birth weight (LBW) and premature births being one of the main causes. In 2018, 14 out of 41 cases of early neonatal death were due to LBW. Studies show that Kangaroo Mother Care (KMC) can prevent or reduce LBW deaths caused by hypothermia, but the implementation is still not evenly distributed. Objective: Describe KMC feasibility as a supporting material for a KMC policy umbrella at Depok City. Method: Qualitative research was conducted with a Rapid Assessment Procedure (RAP) design. A total of 56 informants were divided into 8 discussion groups, 7 in-depth interviews and 2 Focus Group Discussions (FGD). The types of informants were families and inter-sectoral officers. Thematic analysis was used to analyze the data. Results: KMC implementation feasibility in Depok City in terms of facilities and infrastructure was still limited and the quality was insufficient. The number of human resources was still limited, and the competency was still not evenly distributed. LBW family readiness can be maintained if provided with complete and accurate knowledge; therefore, a strong commitment may develop to continue KMC at home. The potential sources of KMC financing are found at health facilities and inter-sectoral; however, to use it, a legal umbrella at the city district level is necessary. Conclusions: The factors of potential financing sources need to be followed up into a priority. This is to overcome the constraints of KMC feasibility implementation.
