The publication highlights a number of the problem aspects of the geoecosystem components pollution of the Black Sea Ukrainian sector by plastic waste and microplastics. On the field research and literature sources processing basis a question review was carried out and certain analytical generalizations were received. Emphasis is placed on the insufficient problem study degree of the shelf Ukrainian part pollution by synthetic and artificial polymers in comparison with similar areas of other Black Sea countries. This determines the need for initial systematization and identification of current research areas on this issue, and the field observations implementation and an information base creation. The conducted field works results in the area of Yuzhne city beach are presented, the main purpose of which was to study the peculiarities of plastic waste and microplastics distribution in current sand deposits and sea suspension of active recreation areas. Analysis of the obtained data involving of similar studies results presented in the available literature shows a low level of Yuzhne beach area pollution compared to some parts of the coast within the Mediterranean, North Atlantic, and Bulgarian sec- tor of the Black Sea. The conducted research allowed gaining practical experience, determining a certain arsenal of field research methods and getting a preliminary idea of pollution degree and plastic waste quality composition within Ukraine coastal city popular recreation area. Further problem state analysis, practical field work and the appropriate laboratory base development will increase the reliability of obtaining and processing data on volumes, sources and routes of plastic waste entry into the Black Sea ecosystems, as well as harmonize the processes of obtaining and processing data in accordance with established global methodologies and techniques.
The results of long-term observations on the geochemical peculiarities of technogenic lead distribution in atmospheric aerosol of Zaporizhia, as well as in soils, bottom sediments, suspended matter from Dnipro river and substance from wet gas filters of open-hearth furnaces PJSC Zaporizhstal are presented. The actual material was obtained on the basis of comprehensive field monitoring during 2015-2019. Simultaneous involvement of data on hydrometeorological conditions (seasonality, precipitation, wind speeds, directions and duration) in the study area provided a integral approach to the processing and generalization of research results. A number of peculiarities of sedimentary substance distribution in air, interrelations of its anthropogenic and natural components are defined. Correlations were revealed between lead concentrations changes and aeolian mineral component distribution, seasonality, and a number of other factors. The highest concentration of lead was found in solid aerosol particles accumulated by the sedimentary trap at the monitoring site. It was revealed that the average concentration of investigated element in river suspension of Dnipro exceeds significantly background values, and for soils exceeds more than 3.5 times the permissible norms. At the same time, the fixed form of lead in atmospheric aerosol, in contrast to other environmental objects, loses its domination, giving the way to easily soluble forms, so the evidence of environmental hazard. Monitoring of seasonal patterns of the element distribution in the city air showed excess concentrations in the cold period of the year, which, according to the authors, is due to both meteorological conditions and redistribution of natural and anthropogenic factors that serve the driving force in processes of arriving and conversion of lead in atmosphere during different seasons of the year.
