Purpose. To determine the contamination level of biotic components of the ecosystem of municipal solid waste landfills in the Kharkiv region by sensitive to anthropogenic changes herpetobiotic arthropods. Methods. The species composition of herpetobiotic arthropods was determined by the Barber's traps method. The occurrence of species was evaluated according to the method of A.V. Selikhovkin. The content of heavy metals (Pb, Cd, Cr, Ni) in the ash obtained from herpetobionts was determined by atomic absorption spectrometry. Results. The research is the first link of the accumulation of heavy metals by mosquitoes as a component of trophic chains. The species composition of herpetobiotic arthropods was determined - 21 species from 15 families. On the territory of Rogan landfill 15 species from 12 families, and Dergachv -12 species from 8 families. The zoning of the territory according to the degree of landscape transformation was carried out and the structure of the species composition of herpetobionts according to the zones was determined. The basic regularities of zonal differentiation of species in technogenic disturbed territories are determined. As a result of assessing the occurrence of species in the study areas, 7 dominant species were identified at two landfills, in the bodies of which the content of heavy metals was determined. The landscape conditions and ecological situation influences the species composition of the herpetobiontic fauna in a direct way, which confirms the monodominant nature of the species on both landfills. Conclusions. Zonal accommodation and the number of studied fauna on two landfills is different, that indicates their high sensitivity to various environmental conditions. Multiple indicators of heavy metals in the organisms of invertebrate’s organisms indicate the potential safety of these animals on the landfills for their consumers.

The presented research is devoted to the study of geochemical transformation of environmental key objects (soils, surface and groundwater) within the solid waste landfills. The object of the study is the one of the largest landfills for solid waste disposal in Ukraine – Kyiv landfill №5. The main factual material, which is the basis of the article, was obtained by the authors during a comprehensive field ecological and geochemical research in 2018-2020. The aim of the work was to determine the geochemical (in particular physical and chemical) features of soil sediments within the landfill, which made it possible to assess the protective properties of soils in relation to the impact of technogenic metals. The condition of surface waters (ponds within the landfill territory) and groundwater (wells in Pidhirtsi village) was also studied; the comparison of the main indicators of chemical composition with the maximum allowable concentrations determined by normative documents was performed. It was found that in the studied soils there is a high concentration of heavy metals associated with the fraction of easily exchangeable ions, as well as an increased content of water-soluble forms. The main migration forms of macro- and microelements in soil solutions have been established. It was found that free hydrated cations and metal-organic complexes are characteristic of heavy metals. For groundwater used for potable water consumption by the population of Pidhirtsi village, exceeding of maximum allowable concentrations were recorded for certain indicators, in particular for nitrates, as well as deviations from the established norms for Ba, SO4, Fe, Mn, Co, Ni, Mo, and Pb. The pond waters, located directly within the landfill territory, are characterized by significant deviations from the norm in terms of Fe, Mn, Ni, Ti, V, Cu and Zn. As a result of the study, it was found that within the landfill there are favorable conditions for the formation of mobile forms of toxic elements and their migration to surface and groundwater

Monitoring Assessment of the Surface Water Quality Within the Areas for the Municipal Solid Waste Disposal

The monitoring ecological hydro-geochemical investigations for the surface waters of the north-western part of Landfill No 5 for the municipal solid waste disposal and the adjacent area are carried out. Based on analyses of surface water samples taken from the existing ponds, it was found that they are polluted by wastewater with the high content of predominantly organic toxicants. Most likely the latter comes from both the Sections and ponds-collectors of leachate or from the pig farm, which is located near the Landfill but hypsometrically higher in relief. More studies are required in order to specify the answer. On the other hand, surface waters beyond the Landfill area are characterized by the ecological and hydrogeochemical indicators, which are not higher than the maximum allowable concentrations, although they are higher than the background ones. This indicates that the considerable outflow of chemical pollutants together with the surface waters from the north-western Landfill No 5 area beyond its borders is absent for more than a year. Only the short-time periodic monitoring of the water bodies within the territory of interest would allow to determine such time intervals when water could be polluted by various toxicants.
