    Environmental pollution in the airport impact area–case study of the Boryspil international airport
    (Environmental Problems., 2020) Radomska, Margaryta; Madzhd, Svitlana; Cherniak, Larysa; Mikhyeyev, Oleksandr; Радомська, Маргарита; Маджд, Світлана; Черняк, Лариса; Міхєєв, Олександа
    The paper presents the analysis of soil and phytomass contamination due to the functioning of air transport. The major issues revealed include extremely high level of soil contamination with petroleum products and an increased content of heavy metals both in soil and phytomass. The toxicity testing has demonstrated considerable pathogenic potential of soil from the airport area.

    Fundamentals of Chemmotology
    (National Aviation University, 2019) Boichenko, Sergii; Yakovlieva, Anna; Vovk, Oksana; Radomska, Margaryta; Cherniak, Larysa; Shkilniuk, Iryna
    The manual presents a modern interpretation of Chemmotology science, its role in development of technology and society. It shows that development and promotion of alternative fuels and Chemmotology problems solving are impossible without systematic approach. In addition, having both theoretical part and practical application, Chemmotology science ensures energy and environmental security of the country's economy, rational use of traditional and alternative fuels and lubricants in operation of advanced modern equipment. The manual focuses on the fact that in recent years one of the most important issues has been the ecological constituent of Chemmotology science, which is aimed at ultra-minimization of negative impact of fuel lubricants and technical liquids on ecosystems. It is well-known that transport sector is an important component of the economy that have an impact on the development and prosperity of the population. Efficiency, reliability of operation of transport, rational use of operating materials depends on their correct selection. According to its quality performance materials must conform to both the model and operating conditions of transport means. The use of poor quality fuels and lubricants leads to a decrease in the durability and reliability of machinery and machine parts; the use of materials of higher quality than required causes unreasonable increase in costs. Thus, knowledge of the range of fuels and lubricants, its functional purpose, operational properties allow using them correctly and efficiently. The authors tried to integrate and systematize in the presented manual the knowledge of many experts from different countries to characterize main trends in the development of conventional and alternative fuels and lubricants, its modern assortment and tendencies in development.

    The assessment of the filling stations impact on the environment
    (National Aviation University, 2020) Cherniak, Larysa; Radomska, Margaryta; Madzhd, Svitlana; Hryb, Alina; Pavliukh, Lesia
    The work is devoted to the environmental impacts of the filling station. Authors have shown that of pollutants, emitted from the filling station, are toxic substances, which often cause irreversible damage to the organism, including functional and system disorders, acute and chronic non-specific and specific effects. The analysis of soil acidity at typical gas stations was carried out, as well as sumpling in the area of filling stations operation. For determination the soils acidity samples were taken at 8 filling stations. Most of the analyzed sites have a soil reaction close to neutral, indicating the presence of pollution with petrochemicals. The drilling results show that there is a serious factor of soil pollution in the operation of filling station. As a result of the analysis of possible impacts at the filling station, recommendations were made for reducing their
