Monitoring of the Influence of Landfills on the Atmospheric Air Using Bioindication Methods on the Example of the Zhytomyr Landfill, Ukraine

Abstract

The paper presents the results of research on the implementation of monitoring of the landfills influence on the atmospheric air using bioindication methods on the example of the Zhytomyr landfill (Ukraine)-one of the typical Ukrainian landfills, which is operated with minimal environmental protection measures. A comprehensive study of atmospheric air pollution in the landfill area was carried out using a human sensor system and an integral assessment using bioindication (lichens were chosen as bioindicators). The study revealed a reliable exponential dependence for modeling the relationship between the distance from the source of gas formation (solid waste landfill in the city of Zhytomyr) and the intensity of odor. The level of atmospheric air pollution was also determined based on the assessment of the projective coverage of the tree trunk with lichens. The research revealed an exponential dependence for modeling the relationship between the distance from the landfill boundary and the total coverage of the tree trunk with lichens. The results of the analysis confirmed the correctness of the use of the aforementioned method. The relationship between the results obtained by the lichen indication method and the strength of the odor from the landfill was evaluated. Based on the results of calculating the relative values of the assessment of atmospheric air pollution by the method of coverage of the tree trunk with lichens and the strength of the odor, a regression analysis was carried out and mathematical relationships were determined, that most accurately describe the change in these indicators with distance from the landfill boundary. It is proved that both tested methods can be used in Ukrainian realities to monitor the state of atmospheric air in the area of influence of municipal landfills, depending on the purpose of research. The analysis of the research results confirmed the significance of the results of the obtained assessment of the impact of the Zhytomyr solid waste landfill on the state of atmospheric air. The materials of these studies can find further application for the formation of databases of knowledge of landfills, which will allow to develop a strategy for managing them as an object of increased environmental hazard.

Integral Assessment of the Impact on Ukraine’s Environment of Military Actions in the Conditions of Russian Aggression

“…At the present stage, more and more attention is paid to environmental safety in connection with the presence of real ecological danger for the environment as a result of the action of many threats of natural, man-made, and socio-political factors. The main technogenic threats include pollution of the Earth's surface with solid household (Popovych et al, 2020, Voytovych et al, 2020) and industrial (Malovanyy et al, 2020, Tymchuk et al, 2020 waste, pollution of surface and groundwater by sewage effluents, as well as hazardous industrial effluents (Malovanyy et al, 2014, Tulaydan et al, 2017, the treatment of which is insufficient at sewage and local treatment facilities, as well as atmospheric pollution by emissions (Ablieieva et al, 2022, Malovanyy et al al., 2021. It should be emphasized that technogenic development is a characteristic feature of today.…”

Determination of the sanitary protection zone of municipal waste landfill based on evaluation of the environmental hazards: Case study of the Zhytomyr territorial community, Ukraine

“…The uncontrolled emission of landfill gas into the atmosphere has several adverse effects, which include the pollution of the surrounding environment with toxic substances that not only pose health risks but also create an unpleasant odor [ 12 , 13 , 14 ].…”

Efficiency Analysis of the Generation of Energy in a Biogas CHP System and its Management in a Waste Landfill – Case Study

“…In the past, waste landfilling followed from the lack of specific policies of the various countries that allowed for the landfilling of the municipal waste stream, which was driven by the high costs of using alternative methods in municipal management. The implemented current legal conditions in the field of biodegradable waste management in the EU countries regulate this area, excluding the storage of bio waste in favor of other available technologies including aerobic and anaerobic processes under controlled conditions [Malovanyy et al, 2021;den Boer et al, 2020;Gronba-Chyła et al, 2021].…”
