“…Many studies have demonstrated the occurrence of hormesis in the growth, reproduction, and swimming behavior of D. magna when exposed to various contaminants. For instance, low concentrations of bioplastics promoted the reproductive rate, while higher concentrations inhibited it [ 54 ]. Similarly, low concentrations of ciprofloxacin and ofloxacin were found to stimulate a shortening of the first oogenesis time and an increase in brood size in D. magna [ 55 ].…”

Methylene blue (MB) is a disinfectant used in aquaculture to prevent and treat fish diseases. However, the release of MB can pose a risk to the receiving water bodies. Zooplankton are the most sensitive organisms among aquatic life. Hence, this study examined the acute and chronic toxic effects of MB on zooplankton using Daphnia magna (D. magna) as a test organism to provide basic data for risk assessment. The results show that 48 h-EC50 and 24 h-LC50 were 61.5 ± 2.3 and 149.0 ± 2.2 μg/L, respectively. Chronic exposure to MB affected the heart rate, beat frequency of the thoracic limbs, and reproductive ability of D. magna at environmental concentrations higher than 4.7 μg/L. The cumulative molts, time to production of the first brood, and total number of living offspring were affected at different MB concentrations, while “abortions” were observed in high-exposure groups. The activity of superoxide dismutase was increased, while glutathione S-transferase activity was stimulated at low concentrations and inhibited at high concentrations. In addition, the malondialdehyde content increased with increasing concentrations of MB. Our findings demonstrate the impact of MB on the reproduction and growth of freshwater species, as well as their physiological responses. These results have implications for establishing guidelines on the use of MB in aquaculture and setting discharge standards.

“…Considering the timely study (Boisseaux P. et al, 2023), it should be noted that the authors investigate bioplastics derived from organic materials other than crude oil, often proposed as sustainable solutions to deal with processed plastic waste, but little is known about their ecotoxicity to aquatic species, which is extremely relevant. to ensure environmental safety.…”

The purpose of the article is to justify the use of digital technologies to ensure environmental safety in the context of the green economy development, taking into account its tasks and principles. The research methodology is a comprehensive approach that makes it possible to comprehensively approach the methods and techniques of scientific knowledge, to carry out a comprehensive analysis of the subject of research, to reveal the essence of the green economy and the purpose of implementing digital technologies to ensure environmental safety, to follow the system-forming connections between economic, social, and ecological processes in a global dimension, to highlight the directions of using digital technologies to ensure environmental safety, which gives a synergistic effect for the development of the green economy. It has been proven that the use of artificial intelligence technologies, information logistics systems make it possible to solve many problems in agriculture in the process of production, processing, transportation and preservation of agricultural products. Highlighting the negative consequences of digitization in relation to the environmental component, which includes the increase in energy consumption, electronic waste and cyber security, made it possible to outline directions for their leveling.
