Summary: The declining O-2 concentrations in the global ocean have led to changes in benthic communities and sediment biogeochemistry. The authors found that below an O-2 threshold of approximately 63 mu M, there were significant shifts in macrobenthic community assemblages and bioturbation rates decreased. This study highlights the importance of bioturbating species in mitigating the biogeochemical consequences of hypoxia and provides insights for predicting future changes in benthic ecosystems.

Summary: This study assessed the impact of intensive human activities on organic matter and heavy metal cycles in Shihwa Lake, South Korea. The results showed that the vertical supply of organic matter was a major controlling factor for benthic respiration, and benthic nutrient flux played an important role in primary production. Higher sediment oxygen demand may accelerate the release of certain heavy metals. The benthic fluxes of certain heavy metals were highest near the industrial complex.

Summary: The Rhone River, one of the main rivers in western Europe, is characterized by distinct hydrological regimes and is facing an increase in extreme events due to the current climate crisis. To study the concentrations and fluxes of suspended particulate matter (SPM) and associated contaminants, a monitoring network called the Rhone Sediment Observatory (OSR) has been established. The main purpose of the OSR is to assess the long-term trend of contaminant concentrations and fluxes and understand their behavior during extreme events.

Summary: We used a network of seismometers near Noumea, the capital city of New Caledonia, to record and analyze earthquakes for 14 months. The earthquakes in southern New Caledonia are smaller but more hazardous due to their shallow depths and proximity to local communities. Our study highlights the need for long-term monitoring of local earthquakes in this region and suggests that current models overestimate the hazard from large earthquakes in nearby subduction zones. Further research is needed to improve ground motion prediction in subduction zone footwall settings.

Summary: Estrogens, such as E2 and EE2, pose a global threat to aquatic ecosystems due to their pseudo-persistence, high estrogenic activity, and toxicity towards non-target species. This study investigated the lethal effects of estrogens on the marine calanoid copepod A. clausi, finding stage-specific responses to E2 and EE2 exposure, with embryos being the most vulnerable and adults showing the lowest sensitivity to acute estrogen exposure. Embryos showed non-monotonic dose-response to low realistic concentrations of E2 and EE2. Fitness of the females of the generation F0 was negatively impacted at higher concentrations of EE2, but A. clausi showed tolerance to environmentally relevant concentrations.

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.
