Assessment of oil pollution of lake ecosystems in Kyiv

Abstract

The object of research - is oil pollution of aquatic ecosystems. The subject of the research - is the assessment of oil pollution of lake ecosystems of the city of Kyiv. The aim of the work - was to study the degree of oil pollution of the lakes of Kyiv in the spring-summer-autumn period of 2019, as well as to identify sources of oil hydrocarbons in reservoirs. Research methods: analytical, chemical, statistical methods of data processing. Topicality. Ecological aspects of water management in Kyiv, in particular the state of pollution of urban water bodies, are becoming more and more socially acute and of national importance, as they are one of the determining factors of national security. Urban lakes play an important role in shaping the ecological well-being of the capital. Within the city of Kyiv today there are 129 lakes that play an important role in maintaining the quality of the urban environment and biotic diversity within the urban landscape. Among the wide range of pollutants entering urban lakes, petroleum products are the most dangerous toxicants, the action of which disturbs the natural ecological balance in water bodies and poses a threat to the safe existence of aquatic organisms. The study of the current state and features of oil pollution of the lakes of Kyiv is relevant in order to assess the potential risk to the life of aquatic organisms and develop a system of measures to prevent their anthropogenic transformation. Practical significance: the results of the study are prepared for implementation in a comprehensive program aimed at protecting aquatic ecosystems and reducing oil pollution of lakes in Kyiv. Personal contribution of the author: elaboration of scientific literature on the topic of work, data analysis of the Institute of Hydrobiology of the National Academy of Sciences of Ukraine, preparation for the implementation of research results.
