Summary: This study focused on Tisochrysis lutea, a commonly used microalgae species in aquaculture, and assessed the potential of photobioreactors with an improved light source and CO2 input to increase biomass production and improve biochemical composition of algal feed. The optimized system showed significantly higher final cell density compared to the conventional culture systems, while the biochemical profile of T. lutea was similar between the two photobioreactor systems. The results demonstrate the potential of LEDs to reduce operating costs for oyster hatcheries and improve microalgae yield without negative effects on oyster spat production.

Summary: This study assessed metal contamination in mudflat sediment cores from different regions of the Chapora Estuary. The results showed variations in metal concentrations within the sediments, which were influenced by hydrodynamics, metal sources, and sand mining. The enrichment factor and geo-accumulation index indicated moderate contamination of manganese, while the potential contamination index revealed moderate contamination of iron, manganese, copper, cobalt, and nickel in certain regions. The study also found that metals were closely associated with iron-manganese oxides and organic/sulfide fractions, which influenced their bioavailability. Manganese, nickel, and zinc in Saccostrea cucullata exceeded permissible limits, indicating their toxicity and unsuitability for human consumption.

Summary: In this study, the levels of mercury (Hg) in polychaete species and sediments from Todos os Santos Bay, Northeastern Brazil were evaluated. The Hg distribution along different body parts of the annelids was also measured. The results showed that Hg levels in the polychaete tissues were higher than those in the sediments. The specific habits, feeding behavior, trophic level, and environmental conditions were found to be the main factors affecting Hg levels in the studied species. The bioaccumulation factor (BAF), contamination factor (CF), and ecological risk assessment (Er) were calculated, indicating low to no significant ecological risk of Hg for the biota and benthonic organisms living in the sediments. Additionally, no statistically significant difference was observed for Hg concentration levels along the polychaete body parts.

Summary: The study found that HMs levels in sediments in karst areas are low, but Cd and Zn concentrations in fish are significantly higher than the soil baseline. Most HMs are present in the residual fraction, with very low proportions of exchangeable fractions that could impact bioaccumulation. Some fish samples exceeded the maximum recommended limit for certain HMs. Environmental factors have a significant impact on HMs bioconversion, especially the proportions of different HM species.

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.
