Ollution of atmospheric air in an industrial city saturated with toxic substances leads to the gain in diseases of the respiratory system. With the aim to identify early pathologies, adolescents living in urbanized areas were examined. There were revealed desquamation, decay of epithelial cells of the nasal cavity and enhanced synthesis of the surfactant according to the condensate of exhaled air, which indicates to a non-specific defeat of the respiratory system by toxic agents. These studies can be used for the development of preventive measures and early detection of diseases caused by unfavorable environmental conditions.

Objectives to reveal cause-and-effect relationships in the system "air pollution morbidity of the population" in a large industrial city. Material and methods.The dynamics of the pollutants concentration, such as formaldehyde and benzopyrene, through the period of 20152017 was analyzed in relation to the indicators of the morbidity of the respiratory system in the population of Samara. In particular, the study focused on the ratio of allergic rhinitis and asthma cases and the concentration of the formaldehyde and benzopyrene. Results.The incidence of respiratory diseases and the general morbidity increased both among children (by 46.7%) and adults (by 11.4%). There was the causal correlation between the effect of benzopyrene on the development of allergic rhinitis and bronchial asthma in children(r = 0.57 and r = 0.76) and in adults (r = 0.45 and r = 0.51) in Samara. The significant differences between the level of the pollutants and the frequency of the respiratory system diseases were registered in children and adults in different areas of Samara. Discussion.As a result of the increase of the maximum allowable concentration (MAC) of formaldehyde in atmospheric air, this pollutant has now ceased to be a priority. The revealed negative correlations point to the absence of an adverse effect of formaldehyde on the development of allergic rhinitis and bronchial asthma in both children and adults in Samara. Conclusion.According to the results of the study, the preventive measures aimed at reducing the impact of main air pollutants on the health of children and adults in Samara were suggested. Their implementation is possible by the immediate informing of the executive authorities to ensure they can make timely management decisions to improve the quality of the environment.

The following paper deals with the problem of historic cultural centers environment transformation on the example of Kimry, the Tver Region. The relevance of the research is defined by the fact that technogenic influence of all environment components on urban areas is actually big. The dense population, abundance of multi-storey residential buildings and social objects are combined with intensive traffic flows, existence of the household and industrial enterprises emanated considerable technogenic flows of toxic substances. The paper contains results of a complex analysis of Kimry ecological state, including assessment of soil cover and atmospheric air pollution, magnetic component of technogenic electromagnetic fields of industrial frequency, air aero ionic composition and acoustic influences. The authors show that the maximum technogenic transformation of environmental material and geophysical components is characteristic for the Kimry central part where difficult infrastructure of the modern city is inscribed in tight space of the historic center. Pollution of soil cover and atmospheric air are due to high concentration of transport and imperfection of highways network. Universal existence of electromagnetic smog and change of air aero ionic composition are caused by low layout of city lighting and electrical power supply networks wiring. As a result the authors offer a number of ways how to improve the ecological situation. Division of business parts and cultural parts of old cities and creation of recreational and tourist clusters in the cultural part could be a cardinal solution of the historic centers problem.

Possible locations in the urban environment where overflows and leaks of oil products may occur are indicated. It is noted that the number of overflows and leaks of oil products in the urban environment is large and they occur constantly. The problems of air pollution in the urban environment from overflows and leaks of oil products are considered, on the example of petrol filling station. It is underlined that air most pollute at overflows and leaks of oil products in urban areas due to evaporation of oil products. The insufficiency of the applied measures at overflows and leaks of oil products is indicated. It is noted that the volume of a single leak of oil products is not known, as a rule. It is indicated that the volume of leak characteristic of the urban environment can be up to fifty liters in accordance with the regulatory and technical document. The areas of petrol leaks, which are typical for the urban environment, are calculated. The intensity of evaporation of pet-rol is calculated and mass flows of evaporation petrol from areas of petrol leaks are calculated on the base of obtained values. The quantitative assessment of mass flow of evaporation petrol from areas of leaks is carried out. The dispersion of petrol into atmospheric air from one square meter of leak is calculated by software. It is shown that there is an exceeding of the maximum single maximum permissible concentration of petrol in the atmospheric air at a distance of several tens of meters from the place of the leak even with insignificant single leak of petrol. It is indicated that there are cases when two or more leaks of oil products occur simultaneously in the urban environment. It is underlined that urbanized areas are characterized by a high density of objects where oil products are applied. It is noted that in the atmospheric air in the urban environment there are al-ready background concentrations of petrol, which are close to the maximum permissible concentration of petrol. Increase of the concentration of petrol in the atmospheric air, which comes from the evaporation of the leak, can lead to an excess of the maximum permissible concentration. The task of updating measures to collect overflows and leaks of oil products is set in the urban environment.

Fine dust: (PM2.5, PM10) is a priority pollutant that contributes to the development of numerous dis-eases in urban areas. The purpose of this scientific work is to study the dispersed composition of dust parti-cles on the leaves of apricot trees (Prúnus armeníaca) in the residential zone of Volgograd. The novelty of the work lies in the study of the dispersed composition of dust particles on the leaves of apricot trees (Prúnus armeníaca) in the residential zone in the city of Volgograd near the construction industry enterprise, me-chanical engineering, leather production and railway transport line in comparison with the conditionally clean (control) zone of the SNT “Orocenets” ”(Sovetsky District, Volgograd) from the standpoint of random functions expressed by integral distribution curves of the mass of particles over their equivalent diameters. As a result of the research, the dispersed composition of dust on the leaves of apricot trees (Prúnus ar-meníaca) in the residential area of Volgograd was revealed. Fine particles were found: PM2.5, PM10 in each of the studied points, which by their values, both in their number and mass fraction, significantly exceed the data on fine dust in a conditionally clean area (control) in the SNT “Oroshanets” (Sovetsky district Volgo-grad), which creates certain environmental risks for local residents. The dispersed analysis of particles from the standpoint of random functions in the future will allow with a sufficiently high degree of accuracy to pre-dict the dust content of urban atmospheric air in the range of monthly and / or seasonal average values compared to the traditional measurement of fine dust concentration in atmospheric air of the urban environ-ment as the maximum single or daily average. At the same time, further studies of dust on the leaves of plants in an urban environment, namely, the study of the density of its sedimentation, will also reveal a group of ur-ban plants that are best suited to retain PM2.5 and PM10 on leaf plates in this region, which can significantly increase the quality of the atmospheric air of the urban environment and be of a recommendatory nature for the state-owned landscaping services of the city of Volgograd when improving the green areas of a megacity.

The annual average rainfall in Busan area is increasing, causing frequent flooding of Busan’s Suyeong and Oncheon rivers. Due to the increase in urbanized areas and climate change, it is difficult to reduce flood damage. Therefore, new methods are needed to reduce urban inundation. This study models the effects of three flood reduction methods involving Oncheon River, Suyeong River, and the Hoedong Dam, which is situated on the Suyeong. Using EPA-SWMM, a virtual model of the dam and the rivers was created, then modified with changes to the dam’s height, the installation of a floodgate on the dam, and the creation of an underground waterway to carry excess flow from the Oncheon to the Hoedong Dam. The results of this study show that increasing the height of the dam by 3 m, 4 m, or 6 m led to a 27%, 37%, and 48% reduction in flooding, respectively, on the Suyeong River. It was also found that installing a floodgate of 10 × 4 m, 15 × 4 m, or 20 × 4 min the dam would result in a flood reduction of 2.7% and 2.9%, respectively. Furthermore, the construction of the underground waterway could lead to an expected 25% flood reduction in the Oncheon River. Measures such as these offer the potential to protect the lives and property of citizens in densely populated urban areas and develop sustainable cities and communities. Therefore, the modifications to the dam and the underground waterway proposed in this study are considered to be useful.

Abstract Population growth in urban areas changes freshwater ecosystems, and this can have consequences for macrophyte communities as can be seen in the municipalities that border the Capibaribe River, Pernambuco, Brazil. This study reports the effects of urbanization on the composition and structure of macrophyte communities in areas along that river. The following urbanized and non-urbanized sampling sites were chosen: Sites 1 and 2 (municipality of Santa Cruz do Capibaribe), Sites 3 and 4 (municipality of Toritama), and Sites 5 and 6 (metropolitan region of Recife). These sites were visited every two months from January to July 2013 to observe seasonal variation (wet and dry seasons). Thirty-one species were identified. Generally, the non-urbanized sites had a higher number of species. Multivariate analyses indicated significant overall differences between urbanized and non-urbanized areas (R = 0.044; p < 0.001) and between seasons (R = 0.018; p < 0.019). Owing to the large variation in physical, chemical, and biological characteristics between urbanized and non-urbanized areas, we found that urbanization significantly influenced the floristic composition and structure of macrophyte communities.

Carcinogenic Effects

Introduction. Environmental factors can cause a gain in prevalence of a significant number of diseases in the population. The effect of various components on the body of children and adolescents becomes especially relevant on the territory of an industrial city, due to its increased sensitivity to adverse effects in connection with the ongoing processes of both growth and development. The article presents the results of an assessment of the non-carcinogenic risk to the health of the children living in the industrial city of Orenburg. Material and methods. The results of laboratory studies of atmospheric air, water from centralized sources of water supply and food products as sources of potential health risks for children living in the city of Orenburg were evaluated. Hygienic and statistical research methods were used. Results. In the industrial city, the priority media that form a high risk of developing non-carcinogenic effects were found to be contaminated food and drinking water, which create a high and very high non-carcinogenic risk for hormonal (up to HI = 13.8), cardiovascular (up to HI = 18.3), central nervous systems (up to HI = 8.3) in children and adolescents and effects on the blood (up to HI = 19.0) and kidneys (up to HI = 8.8), as well as atmospheric air when exposed to the respiratory system (HI = 7.2), which may be one of the reasons for the deviation in their state of health at the population level. Conclusion. The complex multicomponent impact of risk factors on children living in an industrial city is a well-studied problem, the relevance of which does not decrease. Modern concepts of risk assessment make it possible to identify priority environments and their contaminants, which, of course, makes management decisions more focused both at the population and individual levels. The priority media were established to be contaminated with drinking water and contaminated food products, which form a high non-carcinogenic risk for the hormonal, cardiovascular, central nervous systems of children and adolescents and the effect on blood in the long-term dynamics, which may be one of the causes of deviations in their state health at the population level.

The paper deals with the quantification of fine particulate matter (PM10) dispersion in atmospheric air of an industrial city using the AERMOD model by an example of Zhlobin (the Gomel oblast, Belarus). Model input data and procedures for the emission inventory and obtaining spatially distributed estimates are described. Emissions and dispersion of PM10 from the main categories of sources are considered, including industrial facilities, road and off-road mobile sources, domestic sector, and agriculture. It is shown that the main contribution to high PM10 concentrations in atmospheric air is made by industrial enterprises, the domestic sector, and road transport. The spatial pattern of urban air pollution is described. The simulation results are compared with the results of PM10 measurements at the monitoring site, their satisfactory consistency is demonstrated.
