Summary: Marine and ocean water pollution from plastic waste poses a serious threat to future generations, but data on the toxicity of plastic particles are currently incomplete due to their chemical diversity. Organisms have different risks from plastic particles depending on their habitat and feeding habits. We conducted experiments on feeding gastropod scraping mollusk Littorina brevicula with polymethylmethacrylate (PMMA) and polytetrafluoroethylene (PTFE) particles. Results showed that PMMA exposure caused oxidative stress and DNA damage in digestive gland cells, while no similar changes were observed in mollusks fed with PTFE-containing food.

Summary: This study investigated the effects of biochar on earthworms in soil remediation. The results showed that in the presence of biochar, the bioavailability of Cd and 2,4-D increased in earthworms, along with an increase in micronuclei frequency and a decrease in lysosomal membrane stability. Histopathological examination revealed numerous alterations in animals exposed to contaminants without any amelioration when biochar was added. The biochemical response of earthworms demonstrated that in the presence of biochar, animals tended to alleviate the toxicity of Cd and 2,4-D.

Summary: This study investigated the toxicity mechanism of haloxyfop-P-methyl to crustaceans by using transcriptome analysis and physiological changes. The results showed that the median lethal concentration (LC50) of C. dehaani to haloxyfop-P-methyl was 12.886 mg/L at 96 h. Antioxidant system analysis identified MDA, CAT, GR, T-GSH, and GSSG as potential sensitive biomarkers for the oxidative defense response of the crab. Glutathione metabolism, detoxification response, and energy metabolism were significantly enriched, revealing the potential toxic mechanism of haloxyfop-P-methyl to C. dehaani.

Summary: The ingress of nanoparticles of metal oxides and microfragments of synthetic polymers into a marine environment causes unpredictable consequences. However, the effects of these particles are difficult to predict due to a lack of ecotoxicological information. In a laboratory experiment on Mytilus trossulus, it was found that both CuO-NPs and mu PSs induced oxidative stress and had varying degrees of impact on the mollusks.

Summary: Microplastics (MPs) are pervasive environmental contaminants that induce neurotoxicity in various organisms. This study revealed that photoaged polystyrene (P-PS) caused more severe neurotoxic effects compared to virgin polystyrene (V-PS) in zebrafish. Exposure to P-PS altered antioxidant enzyme activity, neurotransmitter levels, and behavior in larval zebrafish. Furthermore, the expression of genes related to neurotransmission and oxidative stress was significantly affected by PS exposure. These findings provide new insights into the potential risks of MPs in the environment.

Summary: Reduced glutathione (GSH) and ascorbic acid (AA) are important antioxidants in mammalian tissues. Knockout mice lacking GSH biosynthesis genes or functional AA synthesis genes exhibited neurological abnormalities and seizures. A study found that the absence of both GSH and AA in mice led to spontaneous seizures and brain damage, but the addition of AA to the diet prevented these symptoms. The interaction between GSH and AA is crucial for normal brain function and neuronal health.

Summary: This study examined the effects of polystyrene nanoplastics on marine mussels and found that nanoplastics induce genotoxicity and oxidative damage in these organisms, overwhelming antioxidant enzymes and causing tissue-dependent toxicity over time. The results suggest that mussel tissues are incapable of coping with the adverse effects of nanoplastics.

Summary: This study assessed the ecological status of Ribeira de Silveirinhos in northern Portugal and found that anthropogenic pressures and climate change have led to changes in the hydrological connectivity and ecosystem functions of the river. The upstream areas, surrounded by Eucalyptus monoculture during drought periods, showed low pH values, while the downstream areas subjected to anthropogenic activities, iron waters, and agriculture had high concentrations of phosphorus. The macroinvertebrate community was also affected by the intermittency of flow. The results indicated that Ribeira de Silveirinhos had a poor to moderate ecological status. However, the protection of intermittent rivers and streams is often overlooked, highlighting the need to consider their specific ecological functioning and adapt planning and management models to ensure ecological quality and conservation processes.

Summary: Estuarine and coastal ecosystems are experiencing fluctuations in salinity due to global warming and extreme weather events, as well as increased water pollution from organic and inorganic compounds. This study investigated the acute and chronic ecotoxicological effects of metformin, an antidiabetic drug, on Gambusia holbrooki under different salinities. The results showed interactions between salinity and metformin, with increased oxidative stress and altered antioxidant capacity, protein content, and glycogen levels. These findings highlight the potential impact of metformin on aquatic organisms and the importance of considering multiple stressors in ecological risk assessments.

Summary: Biopesticides, such as pyrethrum extract (PE), are considered safer and more sustainable for the environment. However, this study found that PE can have acute and sub-chronic toxic effects on Daphnia magna, a non-target organism. The research demonstrated increased oxidative stress and lipid peroxidation in D. magna exposed to PE, indicating an imbalance in their oxidative metabolism.

Summary: This study revealed the importance of zooplankton as a bioindicator for assessing water quality in reservoirs. The current monitoring criteria are insufficient for a comprehensive evaluation of ecological status. By analyzing the zooplankton community, it is possible to accurately determine the water quality and different metrics provide valuable information for assessing water quality status.

Summary: The analysis of Mugil liza in Brazilian waters revealed the presence of two morphotypes (BR1 and BR2), which differed in body proportions and head profiles. The connectivity between individuals from southeast-south Brazil and Argentinean waters was assessed through otolith shape and microchemistry analyses. The results suggest different environments inhabited by the fish along the western coast of South America.

Summary: Tub gurnard, a commercially important Mediterranean-Atlantic benthic species in the Triglidae family, is usually caught as by-catch in Portuguese traditional fisheries. This study used otolith microchemistry to assess the species' movement patterns between brackish and marine waters. The results showed that most individuals had an estuarine-dependent profile, with a clear presence in marine waters during early life history periods. Additionally, the study found evidence of environmental influences on otolith composition, indicating high environmental plasticity and adaptation in Tub gurnard.
