Summary: Limited chronic toxicity data exists regarding the trace element thallium's impact on aquatic biota, hindering the establishment of water quality criteria for this metal. Daphnia magna showed lower sensitivity to thallium under controlled laboratory conditions compared to the current Canadian regulatory guideline value.

Summary: This study investigated the effects of progestogens in mixtures at environmentally relevant concentrations on Daphnia magna for the first time, finding significant impacts on molecular, cellular, and individual levels in both short-term and long-term exposures, including increased gene expression and activity of GST detoxification enzyme, as well as changes in reproductive capacity. Future research should focus on understanding the potential mechanisms underlying these effects.

Summary: The study showed that exposure to MPs-20 and MPs-30 resulted in significant accumulation of microplastics in the gut of D. magna, decreased survival and heart rate. Metabolomics analysis revealed that both MPs-20 and MPs-30 induced significant changes in numerous metabolites in D. magna.

Summary: This study investigated the combined effects of food abundance and zinc oxide (ZnO) nanoparticles concentration on the development and reproductive performance of Daphnia magna. The results showed that high levels of ZnO nanoparticles and low abundance of algae had a negative effect on the life history of D. magna. Higher abundance of algae reduced the negative effect of ZnO nanoparticles, but the negative effect could not be eliminated. The findings highlight the importance of considering food abundance when evaluating the impact of pollutants on zooplankton.

Summary: This research evaluated the effects of different diets on the growth and survival of Daphnia magna. The results showed that feeding the water flea with baker's yeast increased its reproduction and population density, while feeding it with Nannochloropsis oculata increased protein levels. The Daphnia fed with Botrycoccus braunii had the highest lipid and EPA content.

Summary: This study investigated the potential for elevated temperature to alter the toxicity of acetamiprid (ACE) and thiacloprid (Thia) in the ecotoxicity model Daphnia magna. The results showed that the elevated temperature suppressed the metabolism of neonicotinoids and impaired membrane transport activity in daphnids. Additionally, the reproductive performance of daphnids was significantly worsened following neonicotinoid exposures at elevated temperatures.

Summary: With the widespread use of diethylstilbestrol (DES), it has become a common contaminant in the aquatic environment. It is toxic to a wide range of aquatic organisms, disrupting the water flea growth and further interfering with several ecosystem services. Nevertheless, the molecular mechanism of DES in water fleas is still unexplicit. In this study, the 21-day chronic test showed that a negative effect of growth and reproduction can be observed with DES exposure. Transcriptomic analysis revealed that exposure to DES significantly affects energy metabolism, lipid metabolism, the digestive system, transport, and catabolism pathways in D. magna, leading to reduced body length and delayed first spawning time. Therefore, this study emphasizes the threat of DES to D. magna and provides insights into its molecular mechanism.

Summary: The drastic increase of microplastics in aquatic environment is a serious threat to marine and freshwater ecosystems. This study investigated the potential harmful effects of polyvinyl chloride microplastics on aquatic organisms. The results showed that chronic exposure to PVC-MPs affected reproduction parameters, oxidative stress, and gene expression in Daphnia magna, suggesting that PVC-MPs in aquatic environment may cause reproduction toxicity.

Summary: The study found that poor quality food and zinc oxide nanoparticles have combined effects on the development and early reproductive performance of Daphnia magna. They affect the body length, survival time, reproductive time, and number of offspring of Daphnia magna. There are synergistic effects and additive effects between non-toxic Microcystis and zinc oxide nanoparticles, indicating the complexity of their influence. The results of this study are important for realistically evaluating the comprehensive stress effect on zooplankton in complex environments with poor food quality and coexistence of pollutants.

Summary: In this study, the ecotoxicological effects of Pyriproxifen, an insecticide, on the crustacean Daphnia magna were evaluated. Acute toxicity tests, feeding behavior tests, and chronic toxicity tests were conducted on the parental daphnid generation (F0). The results showed that exposure to Pyriproxifen led to a decrease in reproductive parameters and population growth rate in the F0 generation, while the survival rate remained unaffected. Offspring from the F0 generation also exhibited abnormalities in morphology and a decrease in reproductive parameters. Additionally, the appearance of males among the F0 offspring was observed.

Summary: Gender balance refers to equal treatment and opportunities for all genders. In order to achieve this, proactive approaches developed collaboratively from multiple perspectives are necessary. To prioritize the participation of women in radiation-related professions, a special session called 'Women in Radiation' was held at the 15th International Congress of the International Radiation Protection Association (IRPA). This session highlighted various issues related to gender balance and equity/equality and aimed to gather women from different organizations, careers, disciplines, and countries to provide concrete recommendations for action.

Summary: Studies on the effects of ionizing radiation on human health and the environment are important, and structuring this research can support decision making and risk modeling. The adverse outcome pathway (AOP) approach is a useful tool to consolidate relevant research, particularly for low dose radiation exposures. Building a community of experts to understand the strengths and weaknesses of AOPs and promote their use in consolidating knowledge on the impact of low dose ionizing radiation is crucial.

Summary: The study presents the development of a set of consensus Adverse Outcome Pathways (AOPs) for reproductive effects of ionizing radiation in wildlife. It identifies key biological events and causal linkages between ionizing radiation, reproductive impairment, and reduction in population fitness. The AOPs have the potential to assist applications in radiation research, environmental health assessment, and radiological protection. Future plans include further advancement and consolidation of the AOPs through weight of evidence considerations and formal review by the OECD sponsored AOP development program.

Summary: This study quantitatively and spatially evaluated the leachate plume from the Belo Horizonte landfill and found that the leachate contained significantly higher levels of tritium compared to rainfall. The tritium was transported towards the Coqueiros stream, with higher concentration close to the landfill slope. The study also identified factors that contribute to higher tritium levels in certain areas, such as the denser character of the leachate and the presence of rock near the surface.

Summary: The paper presents the results of a long-term experiment on fruit and berry crops grown in conditions of radioactive contamination. The study aims to understand how different species of trees and shrubs accumulate artificial radionuclides, focusing on their absorption through roots from soil. The findings show that the radionuclides are not evenly distributed among the plant organs, with leaves having higher concentrations than branches and fruits. The study also provides quantitative parameters for the transfer and distribution of specific radionuclides in different parts of the crops.

Summary: Public concerns about environmental protection have increased since the Fukushima accident. The soil-plant transfer factor (Fv) is an important parameter for environmental risk assessment. The study investigates the behavior of 90Sr in Brazilian soils and finds that a significant portion of 90Sr remains potentially mobile, mainly in the bioavailable phase. The behavior of 90Sr in these soils is influenced by ionic competition mechanisms and the presence of stable Sr and major nutrients. The mineralogy of the soils also plays a role in the transfer of 90Sr.

Summary: Activity concentrations of 90Sr in fish in lakes within the Chornobyl Exclusion Zone exceed permissible levels, and transferring contaminated fish to clean water does not effectively reduce 90Sr content. Establishing permissible levels of 90Sr concentration only in fish fillet is appropriate for human radiation protection.
