environmental safety

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.

Mining areas are centres of increased environmental danger. This is due to the development and operation of mines and subsequent beneficiation of coal, as well as the storage of significant volumes of empty waste rock in landfills. An important component of ensuring environmental safety is the investigation of the factors and ways of the impact of rock dumps on the state of the environment. In this regard, the article examines the forms of heavy metals found in the rock of the waste heap of the central coal enrichment plant "Chervonohradska" of the Lviv-Volyn coal basin.

The issue of industrial water treatment and food waste disposal is particularly relevant, especially for the alcohol industry. The problem of wastewater treatment and waste accumulation in the process of alcohol production is due to high chemical and biological oxygen demand, specific colour and odour, a large number of suspended substances, low pH. Therefore, the choice of promising wastewater treatment technologies is of paramount importance to ensure the ecological safety of the environment.

In Ukraine, there is still a great number of unused, unidentified and substandard pesticide preparations (PPs) and other toxic substances which have an extremely dangerous impact on humans and other living ecosystems and the environment. Besides, more than 75 thousand tons of pesticides are imported and produced annually in Ukraine, but some of them are not used during the period of their suitability.
