Introduction. Fine dust puts human health at risk in populated areas. The research is focused on dust particles on the leaves of apricot trees (Prúnus armeníaca) in the residential area of the Central Akhtuba district of the Volgograd region (the area of single family houses and low rise townhouses) and in the public area (the area of public amenities) located in close proximity to construction and development enterprises, machine builders, etc. as compared to the dispersion composition of dust on the leaves of apricot trees (Prúnus armeníaca) in the territory occupied by rural housing communities in the conditionally clean zone (the benchmark zone) in absence of any man-induced loadings coming from industrial facilities (Oroshenets gardeners’ non-commercial partnership, Volgograd, Soviet district). The goal of the research is to study the dispersion composition of dust and to identify fine dust PM2.5 and PM10 using plant monitoring systems in the residential area. The objectives include the sampling of dust particles from plant leaves, dust analysis, and identification of areas exposed to ecological risks. Materials and methods. The leaves of apricot trees (Prúnus armeníaca), growing in residential and public areas of the Central Akhtuba district of the Volgograd region and in the territory of Oroshenets gardeners’ non-commercial partnership, Volgograd, Soviet district (the conditionally clean benchmark zone) represent the study material. Methods of research include leaf wash into the beaker full of distilled water, suspension filtration using AFA-VP analytical filter, filtrate production and natural drying at the temperature not exceeding 30–40 °C, and placement of the dried filtrate on the slide of an optical microscope. The distribution of dust particles was performed pursuant to State Standard of Russia 56929-2016. Results. The co-authors have identified the zones exposed to ecological risks in residential and public areas of the Central Akhtuba district of the Volgograd region (Bolnichnaya st., residential houses in Nechayeva, Omskaya streets, a kindergarten in Kavkazskaya st.: PM2.5, PM10) and safe residential areas (a boarding school in Vorovskogo st.: PM10 — 20 μm and 20–40 μm). Conclusions. Further studies of residential and public areas of the Central Akhtuba district of the Volgograd region are to be performed to identify the chemical composition of dust particles and the source of fine dust polluting the air and to develop a roadmap of environmental actions.

A study of the small-dispersed dust chemical composition on the leaves of apricot trees (Prunus armeniaca) in the residential area of the Sredneakhtubinsky district of the Volgograd region was coducted. The aim of the study was to assess the environmental situation in low-rise buildings near functioning constructional and machinery enterprises. The leaves of apricot trees (Prunus armeniaca), growing in the residential area, were used as passive biomonitors. Chemical analysis of dust particles was carried out with the usage of a scanning electron microscope Versa 3D Dual Beam. As a result of the studies, the chemical composition of small-dispersed dust (PM1, PM2,5, PM10) on the leaves of apricot trees (Prunus armeniaca), which consisted of C,O, Mg, Al, Si, Cl, K, Ca, F, P, S, Fe, Mo. Chemical elements such as: F, P, S, Fe, Mo are not specific for leaf blades of apricot trees (Prunus armeniaca) and are environmental pollutants that have fallen on the leaves of apricot trees (Prunus armeniaca) from atmospheric air. In the future, it is necessary to find out the sources of atmospheric air pollution in the residential area by non-specific chemical elements and their compounds for this type of plant in the Sredneahtubinsky district of the Volgograd region, and to develop a set of environmental measures aimed to reduce pollutants emissions into the environment, and improving the quality of life of the population.

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.

Dust Dispersion

The manufacturing of expanded clay represents a certain hazard to the environment and human health. The emissions contain a significant amount of fine dust, and the enterprises are located in close proximity to residential areas. Fine dust particles can stay in the air for a long time, they are transported over long distances thereby increasing the contaminated zone. The OND-86 method (the Industry Regulatory Document) is used to calculate dust dispersion in the atmosphere, which does not take into account a series of factors that determine the dispersion parameters, for example, air humidity. The authors have obtained one-parameter regression equations between the concentration of expanded clay dust in atmospheric air and the influencing factors: air temperature, relative air humidity, distance from the source, wind speed. A strong correlation dependence between the concentration of expanded clay dust and the relative air humidity has been established. An adequate multiple correlation equation that establishes a relationship between the dust concentration and the factors listed has been obtained. The given equation was used in practice when performing dispersion calculations, including the forecasting ones. The authors give the forecast of pollution with expanded clay dust for 2018.

AbstractThe identification of a model organism for investigations of fine dust deposits on moss leaflets was presented. An optical method with SEM enabled the quantitative detection of fine dust particles in two orders of magnitude. Selection criteria were developed with which further moss species can be identified in order to quantify the number of fine dust particles on moss surfaces using the presented method. Among the five moss species examined, B. rutabulum had proven to be the most suitable model organism for the method presented here. The number of fine dust particles on the moss surface of B. rutabulum was documented during 4 weeks of cultivation in the laboratory using SEM images and a counting method. The fine dust particles were recorded in the order of 10 μm–0.3 μm, divided into two size classes and counted. Under laboratory conditions, the number of particles of the fine fraction 2.4 μm–0.3 μm decreased significantly.

AbstractThe site of Sirkeli Höyük in the province of Adana in modern Turkey is one of the largest settlement mounds in Plain Cilicia. In 2012, a geophysical survey revealed that the ancient settlement was not confined to the höyük, but also encompassed an extensive lower town to the southeast of the main mound. To gain information on the dating and development of this part of the settlement, an excavation area (“Sector F”) was opened at a spot where the magnetometry survey suggested the presence of a city gate. Since then, archaeological work in this area has continuously produced new discoveries that help us understand how this residential area and its inhabitants developed throughout the periods of its occupation. Especially the Iron Age (Neo Cilician period) levels, which cover approximately the 11th–7th centuries B.C., provide important information on how this urban center of the Neo Hittite kingdom Hiyawa/Que changed over time and to which extent historical events impacted the people living in one of its residential areas. This contribution discusses the stratigraphic sequence, the pottery, and the archaeobotanical remains discovered in Sector F during the 2013–2019 campaigns, and concludes with a synthesis of the development in this area from a historical perspective.
