The problem of air pollution of the city is still relevant today. A significant increase of emissions of pollutants from the activities of industrial plants, road transport has a negative impact on the quality of atmospheric air and the environment as a whole, the health of the population. The main objective of this research is to assessment of the state of the air environment, by studying of pinus sylvestris needles, growing on the territory of the city of Omsk. For research of the state of the atmospheric air were chosen 5 key sections in the city of Omsk, where we selected samples of needles. It was found, that the severity of damage and drying of needles is uneven on all key sections, depends on the level of air pollution. An assessment of the state of the air environment was carried out, which showed, that on the territory of the Soviet park and ave. of the Culture (sections 1 and 2, respectively) relatively clean air "norm" was established, according to the third level of pollution. Cathedral square and st. Irtyshskaya embankment (sections 3 and 5, respectively) are characterized by dirty air «harmful», according to the sixth level of pollution.

<p>As a result of exposure to plants of various factors associated with anthropogenesis, a huge amount of pollen grains with altered morphological structures and biochemical properties is produced, which affects its fertility and the normal functioning of phytocoenoses. In the present work, using the example of <em>Pinus sylvestris</em> L. growing on the territory of the city of Barnaul as a model object, the possibility of using the quantitative and qualitative characteristics of pollen of plants depending on the state of the bioindication of the state of the environment (primarily atmospheric air) is substantiated. The data used for the analysis were obtained during the six seasons of flowering of <em>Pinus sylvestris</em> (May–June 2010–2015) in six permanent and nine additional observation points in the city of Barnaul located in the territory with a tense and critical ecological state of the landscapes. An analysis of the quality of the pollen was carried out by selecting it directly from the anthers during the active dusting period. As a control, pollen samples collected in the countryside of the Barnaul pine forest belt, which is an isolated and remote vegetation site relative to the industrial zone of Barnaul and large motor roads, were used. As a result of the research, it was found that the points with the highest pollen sterility and teratomorphic grain areas in the zone of very unfavorable ecological situation, which correspond to the areas of the greatest air pollution. More negative impact is shown in the territories located in an accessible proximity to motorways and parking lots. The proportion of sterile and teratomorphic pollen grains at such points is much higher than the reference values, which indicates a large share of the negative impact of emissions of mobile sources of atmospheric air pollution (vehicles) on the change in the morphological, biological and physical characteristics of Scotch pine pollen. Thus, palynoindication analysis can be one of the methods of bioindication of the state of the environment (primarily atmospheric air), as the most accessible and effective method of research and monitoring.</p>

The objective – to study the dynamic changes for the health risk of the population of the industrial center in accordance with the state of atmospheric air pollution with carcinogenic compounds. The assessment of the state of atmospheric air pollution was carried out by us based on the results of physicochemical analysis of samples taken in places attached to the locations of stationary posts of state monitoring. The concentration of identified substances was determined by conventional methods: spectral-luminescent and gas chromatographic. Heavy metal concentrations were determined using data from the Central Geophysical Observatory of the Ministry of Emergency Situations. The calculation of the inhalation load of chemical carcinogens and the risks associated with them (non-carcinogenic and carcinogenic) was carried out in accordance with domestic guidelines. The assessment of dynamic changes in the nature of atmospheric air pollution with a complex of carcinogenic substances was made 5 of them are constantly recorded at levels exceeding hygienic standards. When compared with the reference concentrations, all compounds are characterized by high coefficients, indicating the likelihood of their effect on the body's immune system, respiratory organs, malformations, etc. A high individual carcinogenic risk of the effect of chromium VI and nitrosamines was determined. A total carcinogenic risk is formed at levels of 2.5 – 3.9×10-3, which should be considered as high; this requires development and implementation of preventive measures. On the territory of the industrial center, a high level of air pollution with increased carcinogenic and non-carcinogenic risk is stably registered.

The article provides information about fluctuations in the microbiological composition of waste from the city of St. Petersburg (Russia) and microbiological air pollution at the facilities for the collection and processing of solid waste. It has been shown that the collection sites do not significantly affect the microbiological pollution of atmospheric air. Large MSW landfills have a significant impact on air pollution by microorganisms. Although the effect of plants for mechanized biological processing of MSW on the microbial number of atmospheric air is observed, it cannot be considered statistically significant.

AbstractArkaim is the name given to the site of an ancient town in the Southern Urals, dated to the 17th–16th centuries BC. Discovered in 1987, Arkaim rapidly became more than an archaeological site. It became the focus for an extraordinary congolmeration of ideas linked to ecological and political movements, in particular those of Russian nationalists. Threatened with flooding because of a dam project, Arkaim was made a ‘Museum Reserve’. Soon it became the focus for theories that this was a sacred place and furthermore the home of proto-Slavs. The break-up of the Soviet Union was followed by attempts by Russian nationalists to demonstrate the legitimacy of their domination of the former empire. The article shows how quasi historical claims expanded into myth and fantasy, linked to the emergence of new cults. Arkaim became the city not only of proto Slavs but of Zarathustra and the Aryans too. Such inventions are related to local politics and ethnic tensions as well as to wider Russian nationalism.

The generalizing and comparative characteristic of the level of air pollution of the city of Kamianske is presented. The following indicators are analyzed: the dynamics of total emissions of pollutants; structure of emissions by individual types of pollutants; the level and dynamics of the index of air pollution by priority substances. It is emphasized that the main reason for the declining dynamics of gross emissions of pollutants in the city was the decrease in industrial production, primarily at PJSC “Dniprovsk Metallurgical Plant”. The main economic indicators of PJSC “Dniprovsk Metallurgical Plant” are analyzed and conclusions are drawn about the unsatisfactory financial condition of the enterprise. The dynamics of the main air pollutants of the city is studied. The structure of emissions into the air of the city is analyzed and it is concluded that the share of carbon monoxide is the largest in the structure of emissions of the city and significantly exceeds the national and regional level. In addition, there is an excess of average daily maximum permissible concentrations not only for carbon monoxide, but for other air pollutants, namely formaldehyde, nitrogen dioxide, phenol, ammonia. The dynamics of the index of air pollution by priority substances is analyzed. The following conclusions about the level and dynamics of this indicator in the cities of Dnipropetrovsk region are formulated: for the main cities-polluters of atmospheric air of the region the indicator is quite high, the level of which is characterized as “above average”; during the last three years for Kamianske and Kryvyi Rih the indicator had a steady upward trend; as of the end of 2020 year, the highest value of the indicator is 14.9, which characterizes the unsatisfactory air quality of Kamianske. The dynamics of change of positions of the city of Kamianske according to the index of air pollution in the national rating of cities-polluters is characterized. During the period under study, the city of Kamianske consistently occupied “high” positions: maximum – 1st place (2014 year), minimum – 4th place (2018, 2019 years). The article emphasizes that measures to reduce the level of air pollution in the city should be in line with the regional Program of Environmental Safety and Climate Change Prevention for 2016–2025.

The article examines the state of air pollution in Temirtau, Karaganda region, and the dynamics of the air pollution index (API). The API is calculated based on the 5 main pollutants in the city, namely suspended particles, nitrogen dioxide, carbon monoxide, phenol and ammonia. The article describes the synoptic conditions of atmospheric air pollution in Temirtau, that is, the influence of baric structures, such as cyclones and anticyclones, troughs and ridges, on the maximum permissible concentration of harmful substances and their time in the city air. The meteorological quantity such as the wind contributing to the transport of pollutants is also considered, and a frequency diagram of the wind direction is presented in order to consider the transboundary transport of harmful substances from other regions. The materials of the article used maps of a certain period of time, such as baric topographic maps and terrestrial synoptic maps, and their analysis was carried out. Based on the results of the analysis of maps of a certain period, the article describes the conditions for the occurrence of synoptic processes favorable for the accumulation of large concentrations of harmful substances in the city. The topic under consideration will be interesting to specialists in the field of natural science, politicians and public figures who pay attention to the ecology of our country, in particular to the ecological system of cities with a large industrial complex, such as Temirtau, and to urgent global environmental problems affecting to the state of atmospheric air quality.
