Summary: Paralytic shellfish poisoning is a global issue that requires additional screening methods and rapid testing capacities. This study used 1H NMR spectroscopy-based metabolomics to identify biomarkers of Paralytic Shellfish Toxin (PST) exposure in Alaskan mussels. The research found that high levels of PST contamination in mussels led to alterations in energy and amino acid metabolism, as well as disturbances in osmoregulation. This study demonstrates the effectiveness of 1H NMR-based metabolomics in understanding the biological effects of PST on mussel populations and identifying PST contamination in Mytilus trossulus.

Summary: The soil effect on the micro-component composition of Nero d'Avola wines obtained from different locations was investigated using 1H NMR-based metabolomics. The study found that the differences among wines were not only due to the concentrations of various analytes but also to the characteristics of the H-bond network. Furthermore, the H-bond network was found to be related to the soil properties.

Summary: Developing new tools to assess the health of cultivated shellfish larvae is crucial for the aquaculture industry. In a large-scale trial, mussel embryos were exposed to copper in the presence of EDTA, and metabolomics analysis was used to identify potential biomarkers for monitoring and characterize the mechanisms of metal toxicity. The results showed that low levels of bioavailable copper caused coordinated fluctuations in metabolite profiles, while lethal levels of copper induced severe metabolic dysregulation and cell/organism death.

Summary: The study found that core sediments in the southern region of Youngil Bay originated from the Nakdong River and Chinese rivers, admixed with metals from nonferrous refineries in Ulsan Bay. Core sediments in the northeastern region were found to be similar to the inner bay sample, suggesting that Pb isotopes can be used to determine the transport of contaminants from the inner bay to offshore locations.

Summary: The spatial distributions of dissolved lead concentrations and stable Pb isotope ratios in the Ulleung Basin, East/Japan Sea, were investigated to identify the Pb source, the behavior of Pb in seawater, and the relationship between Pb isotopes and water masses. The results showed that Pb concentrations were highest in the surface layer and decreased with increasing water depth. Near the seafloor in the slope area, Pb concentrations increased due to diffusive flux from sediments. The study also found that the Pb isotope ratios were relatively constant among water masses, with surface ratios similar to coal from China and bottom ratios similar to Russian ore deposits and coal. The isotope ratios of the intermediate layer were constant across the depths of East Sea Central Water and similar to aerosols measured around Ulleung Island, indicating the timing of ESCW formation.

Summary: The study investigated the accumulation, pathways, and sources of anthropogenic lead (Pb) in Ulleung Basin sediments. The results showed that leached Pb concentrations and isotope ratios were stable before 1930 but increased rapidly afterwards. The primary source of anthropogenic Pb was found to be atmospheric deposition of leaded gasoline and coals, but dumping materials added significant amounts of Pb to slope sediments after the 1990s.

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.
