Summary: The acute toxicity of mercury to Clarias batrachus was studied using hematological and biochemical biomarkers at predetermined exposure concentrations. Significant differences were observed in hematological and biochemical variables between exposure groups, with exposed fish exhibiting decreased hemoglobin levels, hematocrit, and total erythrocyte count. The findings suggest toxicant-related anemia and immune-modulation and metabolic disruption. The overall health of mercury-exposed fish deteriorated approximately 3-fold compared to the control group. These observations indicate the potential for greater deleterious effects on less hardy aquatic biota under acute inorganic mercury exposure.

Summary: Tyrosine kinase inhibitors (TKIs) are drugs designed for targeted cancer therapy, and their consumption has been steadily increasing in the past 20 years. In a zebrafish embryo toxicity test, the toxicity of six TKIs was assessed. The study found that imatinib mesylate and dasatinib induced lethal effects, while regorafenib, sorfenib, and dasatinib caused significant sub-lethal effects, mainly manifested as edema, no blood circulation, and formation of blood aggregates. Furthermore, the study demonstrated that exposure to these TKIs disrupted the expression of genes associated with the hormone system. These findings suggest that TKIs may pose environmental hazards and further ecotoxicological studies are needed.

Summary: Leakages of CO2 capture and storage systems can have significant adverse biological effects on marine species. The study found that exposing adult mussels to different CO2 enrichment scenarios for 96 hours resulted in lysosomal membrane deterioration, lipid peroxidation, and primary damages in DNA. The tropical mussel Perna perna experienced mortality and reduced health status after short exposure to pH levels below 7.5. Cytogenotoxic effects were observed in the hemolymph and gills of the mussels after 48 and 96 hours of exposure, respectively. These findings are important for environmental monitoring strategies in tropical marine areas employing CCS.

Summary: Sea levels are rising globally, especially along the eastern coast of the United States. This can lead to saltwater intrusion into freshwater drainages, altering the salinity regimes and causing salinization of coastal freshwater ecosystems. The mixture toxicity effect of sea salt ions on freshwater mussels' early life stages is largely unknown. Acute toxicity tests conducted on three species of freshwater mussels showed that glochidia were more sensitive than juveniles to sea salt exposure. These findings are important for enhancing freshwater mussel conservation strategies in areas affected by climate-induced sea level rise and freshwater salinization.

Summary: Specimens of Sparus aurata were exposed to sub-lethal concentrations of Hg and Cd for 25 days. Bioaccumulation of Hg was highest in gills, while Cd bioaccumulation was highest in the liver. Gills and skin were reliable targets for biomonitoring after short-term exposure. Exposure to both metals caused significant increases in metal concentrations in the kidney and liver. Biochemical analysis showed a reduction in lipid levels and decrease in polyunsaturated fatty acids (PUFA) in the liver, indicating oxidative stress. Molecular markers related to oxidative stress and lipid metabolism were also affected by exposure. The study suggests the possibility of using these biomarkers to explore fish metabolic responses to environmental pollution.

Summary: The salinization of freshwaters poses a global threat to aquatic biodiversity. The study quantified the variation in chloride (Cl-) tolerance among 19 freshwater zooplankton species in four countries. The results showed high variation in Cl- tolerance among populations, with zooplankton community composition being the only factor that explained this variation. The large intraspecific variation in Cl- tolerance suggests that water quality guidelines should consider multiple populations and communities.

Summary: Ecological recovery is often evaluated based on species diversity and composition, but recent studies suggest that considering biotic interaction networks can enhance long-term recovery success. In this study, we analyzed zooplankton community recovery in newly created lagoons using beta diversity approaches and inferred interaction networks. We found that differences in community structure between new and old lagoons increased over time, and the overall interaction network was more complex in new lagoons. Interestingly, the network structure in old lagoons became more complex after restoration.

Summary: Wastewater Treatment Plant (WWTP) effluents are significant sources of antibiotics, antibiotic resistance genes (ARGs), and resistant bacteria, posing threats to aquatic biota and human health. This study explores the impact of the antibiotic doxycycline on the microbiome of Daphnia magna in lab water and treated wastewater media. The results indicate that doxycycline and the media significantly influence the composition of the Daphnia-associated microbiome, with notable changes in Enterococcus spp. Furthermore, doxycycline reduces the presence of Limnohabitans sp. and impairs Daphnia reproduction in lab water, while treated wastewater increases microbiome diversity, richness, and promotes fecundity. The study also detects various ARG genes, including qnrS1, sul1, and blaTEM, with a higher abundance in treated wastewater compared to lab water.

Summary: This study investigates the effects of exposure to 17-α-ethinylestradiol (EE2) on lipophilic extracts of Ruditapes philippinarum clams at 17 degrees C and 21 degrees C. The results show that EE2 exposure at 17 degrees C leads to a slight increase in membrane rigidity at low concentrations, while at higher concentrations, lipid metabolism stabilizes. In contrast, at 21 degrees C, lipid metabolism responds to EE2 at 125 ng/L, with the antioxidant docosahexaenoic acid (DHA) helping to mitigate oxidative stress. The study also identifies new potential markers of stress mitigation, such as high levels of phosphatidylcholine (PtdCho), polyunsaturated fatty acids (PUFAs), and linoleic acid, as well as low PUFA/glycine ratios.

Summary: This study aimed to compare the effects of different exposure methodologies on the ecotoxicological profile of different powder grain sizes of Zn-Al LDH-NO3 and Cu-Al LDH-NO3. The results showed that the serial dilutions methodology was preferable for Zn-Al LDH-NO3, while both methodologies were suitable for Cu-Al LDH-NO3. Thus, the serial dilutions methodology was selected to assess the ecotoxicity of different grain sizes for both LDHs. All Zn-Al LDH-NO3 grain sizes yielded similar toxicity, while smaller grain sizes of Cu-Al LDH-NO3 had a greater effect on microalgae growth.
