This paper presents ecological and biological characteristics of holly maple ( Acer platanoides L.) that hasnt been previously described in the conditions of Donetsk. The authors describe urban environment as a broeksema and transformation in it under the influence of anthropogenic factors. The paper considers the influence of the anthropogenic environment in the city on plant organisms, as well as physiological and morphological changes in them. In the course of the research, a high level of anthropogenic load in Donetsk was determined based on the analysis of vibration and acoustic noise along highways, concentration of heavy metals in soils and concentration of aeropolutants in the air in the study areas. A close relationship between the fluctuating asymmetry index of holly maple leaf plates and the viability index and the level of noise pollution along highways has been established. The authors have studied basic parameters of the mechanical resistance of Acer platanoides L. in Donetsk, in the conditions of technogenic contamination and control (arboretum of the Donetsk Botanical Garden). It is established that young trees (5-7 years old) and the ones that have a low viability score due to the approach of critical age in the conditions of the city are at the greatest risk of breakage. The results can be used in biomonitoring studies of the urban environment state.

The article presents the results of a research of the mesostructural indicators of small-leaved linden leaves in different ecological types of urban plantations. The research was carried out in Naberezhnye Chelny, one of the leading centers of machine building in Russia, where the township-forming enterprise is PJSC “Kama Automobile Plant”. Small-leaved linden is widely used in landscaping of the city. Under the urban environment small-leaved linden exhibits significant increases in anthropogenic load (mainly, with an increase in the API value and formaldehyde content), the number of mesophyll cells and their linear sizes increase.

Abstract Parks in urbanised areas fulfil an important function as they create a positive climate in cities and contribute to the good health of their inhabitants. The study gives an answer to the question of which of the species under investigation is the most suitable for planting in urbanised areas. The aim of the research conducted from 2013 to 2014 at selected sites in Poznan (Poland) was to determine the state of health of Tilia cordata Mill., Acer platanoides L. and Quercus robur L. trees and to compare their state of health depending on the location of the research sites. The aim of the research was also to determine the environmental variables that may have an influence on the state of health of the tree species under analysis. The research included statistical analyses and models based on discriminant analysis. The research revealed that the state of health of the tree species under investigation growing in the city is determined by anthropogenic factors. The closeness of the city centre, main thoroughfares and estates heated with fossil fuels are the factors that have the most negative influence on the state of health of oak, maple and lime trees. Acer platanoides L. was the species in the best state of health in parks, whereas in forests it was Tilia cordata Mill.

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.

The protection of the environment and people’s health from negative influences of the pollution of air as a medium of the environment requires constant observing of the air quality in accordance with international standards, the analysis of emission and imission of polluting matters in the air, and their connection with the sources of pollution. Having in mind the series of laws and delegated legislations which define the field of air pollution, it is necessary to closely observe these long-term processes, discovering cause-and-effect relationships between the activities of anthropogenic sources of emission of polluting matters and the level of air degradation. The relevant evaluation of the air quality of a certain area can be conducted if the level of concentration of polluting matters characteristic for the pollution sources of this area is observed in a longer period of time. The data obtained by the observation of the air pollution are the basis for creation of the recovery program of a certain area. Vranje is a town in South Serbia where there is a bigger number of anthropogenic pollution sources that can significantly diminish the air quality. The cause-and-effect relationship of the anthropogenic sources of pollution is conducted related to the analysis of systematized data which are in the relevant data base of the authorized institution The Institute of Public Health Vranje, for the time period between the year of 2012. and 2017. By the analysis of data of imission concentrations of typical polluting matters, the dominant polluting matters were determined on the territory of the town of Vranje, the ones that are the causers of the biggest air pollution and the risk for people’s health. Analysis of the concentration of soot, sulfur dioxide and nitrogen oxides indicates their presence in the air of Vranje town area in concentrations that do not exceed the permitted limit values annually. The greatest pollution is caused by the soot content in the air, especially in the winter period when the highest number of days with the values above the limit was registered. By perceiving the influence of natural and anthropogenic factors, it is clear that the concentration of polluting matters can be decreased only by establishing control over anthropogenic sources of pollution, and thus it can be contributed to the improvement of the air quality of this urban environment.
