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.

The purpose to highlight and focus on the most important risks of forest fires in radiationcontaminated areas, with some detailing of the problem in the Chernobyl Exclusion Zone (CEZ). The search strategy was to collect a sufficient number of relevant publications in ScienceDirect, PubMed, Mendeley, ResearchGate, GoogleScholar from 2006 to the present in English, Russian, Ukrainian. Requests were made on the topics "Forest fires in a radioactively contaminated area" and "Assessing the territories' radiation safety", as well as for the keywords of this study. Analysis of available open information about the CEZ was done. Although, in the future, temperatures are expected to rise in contaminated forests, and the amount of precipitation will remain the same or slightly decrease, which will contribute to an increase in the frequency of fires. Considering the socio-economic situation in Ukraine, the introduction of early detection systems is more profitable than the elimination of the consequences of such emergencies. Investigations have been studied, which were published after 2006 only in English, Russian, and Ukrainian. The most attention is paid to Chernobyl Exclusion Zone. Despite the fact that a lot of studies are devoted to the study of the ecological situation in radioactively contaminated areas, many issues related to safety still concern the population living in this area. The reason for this is intermittent fires, which again and again cover large areas with smoke and cannot be extinguished for a long time. To eliminate anxiety, it is necessary to convey truthful information to the population in the most accessible and convincing way. It was a critical look at numerous studies in this area that made it possible to present concentrated information understandable for most segments of the population. The document concentrates on the most key problems of fires in radioactive forests, shows the intensity of the radionuclides impact on the population and the exposure ways, as well as the probable risks. Such information is necessary to reduce the psychological stress that can be caused by the media influence. Objectively understood situation promotes constructive action in extreme conditions and reduces the likelihood of panic.
