Summary: Research shows that selenium exposure may reduce MeHg bioaccumulation and toxicity, but does not affect the MeHg concentration in diatoms under high MeHg treatment. Only in high MeHg treatment, the addition of SeMet leads to a decrease in mayfly MeHg concentrations and biomagnification factors. However, Se is toxic to mayflies, causing negative effects such as reduced escape behavior and prolonged metamorphosis time.

Summary: The study aimed to identify mercury-associated protein spots in the liver tissue of rats exposed to low concentrations of mercury and examine their physiological and functional aspects. Proteomic analysis of the liver tissue of Wistar rats exposed to mercury chloride was conducted, revealing 10 mercury-associated protein spots. LC-MS/MS analysis identified 11 metal binding proteins in these spots, with some showing higher mercury concentrations and downregulation, and others being expressed only in the Hg-60 group. Bioinformatics analysis suggested that these proteins, such as GSTM2, Acaa2, and Bhmt, may serve as potential biomarkers for mercury exposure.

Summary: Bioaccumulation of mercury in freshwater fish is a complex process influenced by environmental and biological factors. While surface water mercury concentrations were high in the studied tributaries of the Red Deer River, patterns of fish THg concentrations varied by species. The study suggests that mercury poses a risk to piscivorous wildlife health in these streams, but bioaccumulation is not solely driven by environmental factors and commonly associated factors like body size and trophic level may not strongly influence mercury concentrations in these ecosystems.

Summary: The study found that mercury accumulation in the liver of zebrafish exposed to mercury-contaminated food was faster compared to other tissues, while the gills exhibited the fastest depuration rate. The bioaccumulation factor values of mercury in the liver and muscle increased linearly during the uptake period, indicating that zebrafish needed more than 4 weeks to depurate mercury effectively. The distribution of mercury in the water column also showed differences between the accumulation and depuration periods.

Summary: This study used an optimized and validated QuEChERS protocol to extract and quantify 21 insecticides and 5 metabolites in seafood samples (crustaceans, bivalves, and fish-mudskippers). Seven species from the poorly monitored Hong Kong and Macao wet markets were selected based on their commercial importance, abundance, and affordability. The results showed high concentrations of insecticides in mussels from Hong Kong and mudskippers from Macao, suggesting potential health risks, such as neurotoxicity and carcinogenicity, associated with the consumption of fish, bivalves, and crustaceans from these markets. Strict monitoring measures should be implemented to improve the quality and safety of seafood products.

Summary: A fish trial was conducted to assess the effects of temperature and dietary lipid level on the body composition, growth performance, and freshness profile of the European seabass. The study showed that fish reared at 24 degrees C had lower lipid levels and higher daily growth index compared to fish reared at 20 degrees C. Sensory and microbiological analysis further revealed better freshness conditions in fish reared at 24 degrees C. However, dietary lipid level did not impact fish freshness. These findings suggest that increasing the temperature to 24 degrees C is beneficial for the growth and freshness profile of this particular species in aquaculture.

Summary: Anthropogenic-mediated climate change has a severe impact on the oceans. Marine heatwaves (MHWs) are defined as water temperatures exceeding the 90th percentile threshold values based on the last 30 years' average, and persisting at this level for five or more days. There is growing interest among the scientific community in studying MHWs, driven largely by their impacts on marine ecosystems. These extreme events have serious consequences for decapod crustacean species and also affect socioeconomic activities such as fisheries and aquaculture.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
