The main features associated with the development of intelligent technology for detecting anomalies of ecosystems in the waters of the city of Sevastopol are considered. An approach is proposed, the feature of which is to ensure continuous monitoring of key environmental indicators presented in the form of heterogeneous information flows: hydrometeorological information, data on the level of pollution and air composition, soil, environmental monitoring, monitoring of maximum permissible emissions of harmfulsubstances in order to detect changes in the state of data flow monitoring. The proposed method for thedetection of anomalies of ecosystems of the water area is based on data clustering. We consider typicaloperations on clusters and main metrics based on the Kullback information measure.

In the water body monitoring and quality management system the identification of negative impact sources is of high importance. The most striking example of anthropogenic changes of nature is pollution, that is introduction into the environment of substances and energy, alien for it, or peculiar to it, but in the concentration exceeding background indicators. Inventory of anthropogenic polluters of water ecosystems was carried out on the example of the Voronezh reservoir which is influenced potent impact of the city agglomeration surrounding it. The article presents the results of the carried out inventory. As the main sources of anthropogenic pollution of the water area of a reservoir leading to transformation of quality of waters were allocated: activity of the production enterprises, farming, transport and activity of the population of the city and suburbs. The pollutants allocated in a surrounding medium from these sources get to a reservoir with household drains; production sewage; atmospheric precipitation; a thawed and rain drain from the territory (including from the production platforms, farmlands, personal subsidiary farms); livestock production drains; underground waters; washing waters of water lifting stations; the water mass of the Voronezh River and the small city water currents coming negative impact of all listed above sources. The researches of chemical composition of snow cover of various functional zones of the city of Voronezh which are earlier conducted by the author showed that thawed snow contain the significant amount of the pollutants leading to adverse changes in a surrounding medium. Paths of migration of pollutants demonstrate ekologo-geochemical coherence of the water area of a reservoir and the adjacent territory. Following the results of a research the chip of sources of anthropogenic pollution, as well as the routes of pollutant movement in various environments and input to a reservoir has been developed. The practical significance of the developed scheme input to the possibility of its use for adoption of efficient administrative decisions by authorities in the field of regional water management policy.

The article is dedicated to the 125th anniversary of the birth of the outstanding Russian pediatrician, Academician Aleksandr Fyodorovich Tur and the 75th anniversary of the lifting the siege of Leningrad in the Great Patriotic War. Professor A.F. Tur directly participated in the organization of medical care for children in the besieged city of Leningrad, for 10 years he was the chief pediatrician of the city. The experience of the work of children’s polyclinics in Leningrad on the basis of a single pediatrician subsequently became the property of the whole country. A.F. Tur made a huge contribution to the protection of children of the besieged city, directed the Children’s Nutrition Board, proposed original methods for combating alimentary dystrophy, helped to create a system of rigorous provision of children with food, shelter, fuel, organization of the correct regime in shelters, and continuous monitoring of vaccinations for children. The Society of Pediatric Doctors headed by Prof. Yu.A. Mendeleva and A.F. Tur was one of the first to renew its meetings in the besieged Leningrad. The name of A.F. Tur is associated with the establishment of domestic dietetics, neonatology, pediatric hematology, pediatric endocrinology. Among his students, there are more than 110 candidates and 28 doctors of medical sciences. In peacetime, A.F. Tur was awarded two orders of Lenin, in 1970 he was awarded (jointly with G.N. Speranskii and Yu.F. Dombrovskaya) the title of the Laureate of the Lenin Prize “... for a series of works on the physiology and pathology of young children, contributing to a sharp decline in morbidity and mortality among them».

The Zagreb 2020 earthquake severely damaged the historic centre of the city. Most of the damage occurred on historic masonry residential buildings, many of which are situated very close to the tram track. Although traffic-induced vibrations generally do not affect surrounding buildings, they can be harmful to buildings damaged by a previous earthquake. Vibrations could contribute to the further propagation of existing cracks. The effect of vibrations depends on many factors, one of the most important being the distance between the track and the building. The vibrations are highest at the source, and the energy loss occurs due to transfer through the soil to the recipients. The impact of tram-induced vibrations on earthquake-damaged buildings in the city of Zagreb is investigated in this paper. The analysis is conducted on a tramway network scale to identify critical locations by performing continuous monitoring on the tramway network and risk analysis based on the distance of buildings from the track, vibration amplitude at source, and building damage. Further investigation is based on the level of buildings to evaluate the influence of vibrations on actual buildings damaged in the Zagreb earthquake. Based on detailed signal analysis, the vibration characterization is performed, and the influence on damaged masonry buildings is evaluated.

This study examines the stocks of building materials in Toronto’s in-use and annual obsolete single detached housing, to provide potential environmental benefit parameters for city scale material reuse and recycling. The material volumes of five archetypes, developed to represent typical Toronto housing, were measured and extrapolated to the city scale. Applying established criteria for reusability and recyclability, city scale reusable and recyclable stocks were determined for three environmental indicators: material volume headed to landfill, carbon dioxide emissions, and primary energy consumption. It was determined that 61-66% of the material volume in Toronto’s in-use and annual obsolete housing could be reclaimed for reuse/recycling, and was mostly composed of masonry, concrete, and framing lumber from houses built from 1930-1960. Additionally, annual obsolete reusable materials represented an embodied carbon of 2,287-4,116 tonnes and energy of 52,883-95,189 GJ. By addressing common barriers to widespread uptake of reuse/recycling, Toronto could reap these determined potential environmental benefits.

Relevance. The greatest threat to human health is provided by the suspended particular mater with an aerodynamic diameter of 10 μm or less. Since they can lead to an increase of frequency of respiratory and cardiovascular diseases and contribute to an increase in mortality from these diseases. Objective. The research was aimed to carrying out a hygienic assessment of the particular mater content of the PM4 and PM10 fraction in the atmospheric air and in the air of the working area of the metallurgical enterprises. Materials and methods. It was performed the 4000 studies of PM4 and PM10 concentrations in the atmospheric air and 1838 - at workplaces. The study was carried out using a piezo-balanced measuring instrument for mass concentration of respirable dust - KANOMAX 3521. Results. Monitoring of atmospheric air showed that PM4 and PM10 are constant components of atmospheric air in the city of Zaporizhzhya. It was found that the maximum one-time concentrations of PM10 in the ambient air exceeded permissible concentration 20-minute mean only in sporadic cases, with the multiplicity exceeding 1.1-1.2 times. But daily average concentrations of these substances systematically exceeded recommended levels in 1.5 times. It was established that in the agglomeration, in the blast furnace guild and in the open-hearth guild departments the PM10 and PM4 content in the air of the working area was 21.2 and 16.0 times, 31.8 and 24.4 times and 15.5 and 13.2 times more than at workers of factory management, respectively. Conclusion. Organization of constant continuous monitoring of PM content in the air is a prerequisite for a correct assessment of their impact on the health of the population and workers.

The article highlights the quantitative and qualitative characteristics of phytoplankton organisms in the water area of the Middle Caspian Sea studied by sections: the city of Makhachkala-cape Sagyndyk, the city of Derbent - cape Sandy, Divichi village - Kenderli bay in 2019-2020. The saprobity index and the corresponding saprobity zone of the studied areas have been determined. It has been found that the dominant group was presented by diatoms (43% of the total com-position). The subdominants were dinophytic algae. The basis of the ecological complex of 2019-2020 was made up of representatives of freshwater groups of algae. Only on the section of Divichi village - Kenderli bay there dominated the species of marine origin. Quantitative indicators of phy-toplankton, both in the Middle Caspian as a whole and by sections, in 2020 decreased compared to the previous year. The general part of the biomass was formed by a large diatom Pseudosolenia calcar-avis and representatives of the group of dinophytic algae. The leading role in the abundance figures of the Middle Caspian in 2020 was played by small-cell phytoplankton, mainly from diatoms - Thalassiosira hustedtii, Thalassionema nitzschioides, Aulacoseira granulate, species of the genus Fragilaria. The highest quantitative indicators of 2020 were noted in the section of the city of Makhachkala-cape Sagyndyk in the productive layer of 0-25 m. In 2019-2020, the saprobiological state of the waters of the Middle Caspian was characterized as moderately polluted
