Spatiо-Temporal Study of the Ecological State of Water Bodies Located within the Detached Objects of the Urbanized Territory of Ukraine

Abstract

The paper considers the impact of urbanized areas on the state of water bodies. The impact of various types of anthropogenic activities on water bodies located in cities was shown. In towns, there is worse water resource management than in large cities and the necessity of conducting more detailed research. Using the method of direct conductometry, a spatio-temporal study of the ecological state of water bodies located within the detached objects of the urbanized territory of the Ukraine was carried out using the example of Popasna town. It was shown that fluctuations in the electrical conductivity of these bodies are mainly due to the influence of surface runoff. It was found that in all studied ponds there was a significant drop in the electrical conductivity of water in March 2021, followed by an increase and stabilization in April and May 2021, the characteristic values of electrical conductivity range from 200 to 2900 μS, the relative standard deviation did not exceed 1.5%. The necessity of conducting further, more detailed study of the features of the influence of surface runoff on the water condition in the studied ponds was shown for the purpose of rational management of these water bodies.

Analysis of the Influence of Anthropogenic Factors of the Urbanized Territory of Poltava Region (Ukraine) on the State of River Water

“…The impact of the urbanized area is considered in more detailed way for a number of water bodies in Popasna (Ukraine). Changes in the parameter of electrical conductivity under the influence of surface urban runoff were noted for a number of reservoirs of this city in the work [Loboichenko et al, 2021b]. The predominant influence of surface runoff on individual ponds in Popasna was noted.…”

Correlation Between Ecological Status of Sedati Waters and Gonadosomatic Index of Short-Necked Clam (<i>Paratapes undulatus</i>)

“…From the results of the study, the temperature obtained was extreme because the monthly differences were quite significant. This will cause the clams not to grow optimally and make the size of the clans small with a high gonadosomatic index because the size of the mature gonads is too early (Yan et al, 2014;Loboichenko et al, 2021).…”

The River System Pollutant Migration in the Context of the Sudden One-Time Discharge with Consideration of the Bottom Sediments Influence (Case of Benzene Migration in the Stryi River, Ukraine)

“…Then several settlements may be deprived of drinking water supply at the same time. Therefore, the river systems water quality constant monitoring is a necessary condition [Odnorih et al, 2020;Loboichenko et al, 2021b]. Mathematical models of hydrocarbons migration in the river are an important tool to prevent such emergencies.…”
