environmental safety

This article discusses the issue of sludge water treatment generated in the production of ceramic sanitary ware. Experimental studies were conducted on the effectiveness of physical and chemical treatment methods, in particular the use of coagulants (aluminium sulphate) and flocculants of various types (anionic, non-ionic, cationic). The optimal parameters for water treatment have been determined, which allow for the maximum removal of suspended particles and minimise the formation of sediment.

We have assessed the environmental risks caused by the lack of hazardous waste treatment facilities in the industrial region. We have identified such environmental threats as the release of hazardous waste into the environment, uncontrolled flows of hazardous waste that may end up in municipal landfills as household or other hazardous waste. A critical analysis of the existing modern infrastructure in Ukraine, on the basis of which hazardous waste management is carried out, was conducted. The problem of generation and disposal of hazardous waste in the Poltava region was analyzed.

. The article is devoted to the study of the causes and consequences of the anthropogenic impact of the construction industry on the environment, with a special emphasis on the use of radon-containing materials in the production of construction products. The key factors that cause environmental pressure, such as raw material extraction, technological processes, insufficient waste disposal technologies, and weak regulatory control, are analyzed.

The article presents the results of a study aimed at developing a mobile cyber-physical system for monitoring and analyzing radiation background, addressing current challenges in environmental safety. The relevance of the topic stems from the need for rapid response to radiation incidents, insufficient coverage of existing stationary monitoring systems, and the necessity to involve the public in environmental control processes.

This study employs state-of-the-art analytical tools to investigate the ecotoxicological impacts of mercury contamination on aquatic macrophytes in post-military zones, focusing on Typha latifolia and Lemna minor as model organisms. The research methodology integrates multiple analytical techniques: spectrophotometric chlorophyll quantification using the Holm-Wettstein method, atomic absorption spectrometry utilizing a C-115PK Selmi spectrometer (precision ±0.001 mg/L), and fluorescence analysis via Flyuorat-02-Panorama spectrofluorometer.

Emissions of industrial enterprises in their structure are mostly aerodisperse systems, in which the dispersed phase is organic and inorganic dust or fine droplets, and the dispersion phase is a gas-air mixture. This mixture may comprise several contaminating gaseous components. In many cases, the components of the exhaust gases have an additive effect or are capable of transforming into more dangerous compounds, which in the conditions of background concentrations characteristic of most industrialized areas makes them dangerous even at relatively low concentrations in emissions.

The article is devoted to the study of the legal aspects of the implementation and effectiveness of the environmental audit in the concept of the development of sustainable nature management as an important mechanism of environmental security.

The ongoing military conflict in Ukraine has severely contaminated freshwater ecosystems with heavy metal pollutants including lead from ammunition and explosives. This study investigates the physiological and biochemical mechanisms of resistance in the freshwater mollusks. This study examines how freshwater mollusks, specifically Planorbarius corneus and Viviparus viviparus, resist lead compounds. Lead pollution from military activities poses a significant threat to aquatic life due to its toxicity and bioaccumulation.

The water resources of Zhytomyr region are an important national asset, the condition of which affects people's health, economic development and the "good" environmental condition of the region. The current state of water resources in Zhytomyr region is of some concern due to a number of challenges, including: water pollution with organic materials, nutrients and toxic elements due to incomplete or no wastewater treatment, leaching of pollutants from agricultural land and plastic waste.

The article is devoted to the analysis of administrative and legal principles of management in the field of ensuring environmental safety of the state. 

The object of administrative and legal regulation has been established – social relations in the form of behavior and actions of people that take place in connection with the provision of public authorities, environmental rights and freedoms of man and citizen, the interests of society and the state in this area.
