Summary: Surfactants, particularly sodium lauryl sulfate (SLS), are commonly found in coastal systems and can have negative effects on organisms. This study aimed to analyze the impact of SLS under climate change conditions, specifically ocean acidification and warming. The results showed that SLS exposure led to increased metabolic activity and protein damage, with higher temperatures having a greater impact.

Summary: This study evaluated the impacts of ocean warming on two pharmaceutical drugs, Carbamazepine and Cetirizine, in the edible clam Ruditapes philippinarum. The results showed limited effects of the drugs at control and warming conditions, with warming improving the oxidative status of contaminated clams, especially when both drugs were combined. Defense mechanisms were activated under higher stress levels, highlighting the need for further research on this topic due to increasing marine heat waves and pollution levels.

Little is known about the effects of MHWs on bivalves, especially their digestive metabolism. This study investigated the impact of MHWs on the digestive metabolism of pearl oysters and found that increasing MHW intensity led to enhanced digestive enzymatic activities but negative effects on lipid metabolism, amino acid metabolism, and B-vitamins metabolism.

Summary: Coastal areas, especially estuaries and coastal lagoons, are highly vulnerable to anthropogenic activities and climate change-related factors. The release of lithium (Li) into aquatic systems from industries and the lack of understanding of its consequences pose a significant concern. This study assessed the effects of temperature rise and salinity changes on the impacts of Li pollution in clams (Venerupis corrugata) collected from a coastal lagoon in Portugal. Salinity variations had a greater impact on biochemical responses than temperature increase, even in the presence of Li. The combination of Li with low salinity was the most stressful treatment, suggesting potential imbalances in coastal ecosystems under extreme weather events.

Summary: Studies have shown the presence of nanoparticles, particularly carbon nanotubes, in aquatic ecosystems, raising concerns about their toxicity when combined with other pollutants. This study evaluated the effects of carboxylated multi-walled carbon nanotubes and chromium on the metabolic capacity, oxidative status, and neurologic status of two filter feeder organisms: Ruditapes decussatus and R. philippinarum. Results revealed species-specific accumulation of chromium, with higher values in R. decussatus. Only R. philippinarum showed inhibition of antioxidant defenses and neurotoxic effects. The interaction between contaminants did not affect antioxidant enzyme activities and neuro status. However, the combined exposure to both contaminants altered the metabolic capacity of R. decussatus. Both clams were tolerant to the contaminants but showed a significant accumulation capacity, posing a potential transfer of contaminants to humans.

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.

Summary: Bioactive natural products from marine invasive species and synthetic pharmaceutical drugs released into the marine environment may have similar ecotoxicological impacts. In this study, the alkaloid caulerpin (CAU) from the invasive green algae Caulerpa cylindracea and the synthetic lipid-lowering drug fenofibrate (FFB) were compared for their effects on Mytilus galloprovincialis. The results showed that FFB had harmful effects on the mussels, causing metabolic impairments, cellular damage, and changes in enzyme activity. In contrast, CAU did not produce any significant alterations. These findings highlight the importance of avoiding the release of synthetic drugs into the environment and suggest the potential use of CAU as a natural product in drug discovery.

This critical review discusses the degradation and toxicity of face mask contaminants and emphasizes the need for more research in this area. The lack of studies on biodegradation and ecotoxicity, as well as the uncertainties in experimental procedures, hinder the comparison with conventional plastic debris. Further studies on the abundance and composition of face mask-released contaminants and the development of methodological strategies are crucial to understand their environmental impact.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
