Summary: Assessment of microplastic contamination in Arcachon Bay, France was conducted, covering sea surface, water column, intertidal sediments, and wild oysters. Spatial variations in concentration and composition were observed in sea surface and water column samples, while sediment and oyster samples showed no significant differences. Different stations exhibited distinct patterns, with higher concentrations and a variety of polymers at outside stations. The presence of fiber-shaped particles was prominent in most samples. Overall, microplastic pollution was found to be ubiquitous across all stations and sample types.

Summary: Chronic hypoxia has a strong impact on coastal ecosystems, with the Berre lagoon experiencing such effects for decades. The demand for oxygen in sediment varies depending on seasonal and long-term hypoxia, influenced by factors such as oxygen availability, sediment properties, and biological disturbances.

Summary: PFAS concentrations in the Jiulong River water showed seasonal variations, with higher levels during the dry season. Long chain PFAS exhibited high bioconcentration factors (BCFs), while short and medium carbon chain PFAS had weak bioconcentration capacity. The hazard ratios (HR) suggested that frequent consumption of river fish may pose health risks to local population.

Summary: In recent years, the synthesis of artificial humic substances (A-HS) through alkaline hydrothermal processing of waste biomass has been described. These A-HS have shown to have various effects on soil, including water and mineral binding, soil structure alteration, inhibition of fertilizer mineralization, and promotion of plant growth. The observed macroscopic effects have been attributed to the stimulation of the microbiome, which plays a key role in this anthropogenic soil system. By understanding this complex system, it is possible to address global issues such as soil fertility, nutrition for a growing population, and climate change.

Summary: Plastic marine debris has been found to have a negative impact on marine organisms and the environment. This study investigated the presence of microplastics in the Nigerian Lagos Lagoon ecosystem and found that they were present in the water, sediment, and certain fish species. The contamination was primarily due to plastic debris from recreational, industrial, and domestic waste. Urgent measures are needed to protect Nigeria's coastal and marine ecosystems from plastic pollution.

Summary: Coastal social-ecological systems (SES) are vulnerable and rapidly changing due to their multiple uses and exposure to different stressors. A methodology combining timeline approach and time series analyses was proposed to analyze co-evolution and regime shifts in SES. This methodology was tested on the Thau lagoon on the French Mediterranean coast, revealing the dynamics of SES driven by interactions between crises and management adaptations. The study identified cause-and-effect relationships and highlighted periods of stable emerging properties. This long-term approach can aid in increasing the resilience of coastal SES and addressing challenges posed by global climate change.

Summary: The study investigated the metal concentrations in water, sediments, and mollusks in the Manguaba Lagoon, with lead concentrations above the Brazilian legislation limit. Despite high metal concentrations in the environment, key contaminants were not detected in the mollusks consumed by the local population. The findings suggest that humic substances play a significant role in retaining contaminants and making them unavailable for absorption by mollusks in the lagoon.

Summary: The aim of this research is to investigate the occurrence of mercury (Hg) bound to settling sediment particles (SSP) in the Gulf of Trieste and assess the sedimentary Hg fluxes. The concentration of Hg in the settling sediment particles ranged from 0.61 to 6.87 μg/g, indicating the ongoing contamination from the Isonzo River inputs. The daily Hg fluxes showed significant variability, reaching maximum values following periods of high river flow.

Summary: This study investigated the spatial distribution and sediment record of persistent toxic substances (PTS) in urban lake sediments in the middle Yangtze River Basin, showing pollution concentration in certain areas due to inputs from petrochemical and municipal wastewaters. The sediment record revealed an increase in PTS concentrations over decades, followed by a decrease likely due to wastewater treatment plant improvements.

Summary: In this study, the occurrence of PFOS and PFOA in sediments, pore water, and bulk water from Lake Neusiedl in Austria was assessed, and the mechanisms regulating the adsorption and remobilization of these substances were investigated. The results showed that the adsorption capacity was mainly influenced by organic matter content, oxide composition, and pre-loading of the sediments. Sediment transport and adsorption to sediments in the reed belt were found to partly buffer the increase of PFAS concentrations in the lake. However, there was a real risk for mobilization of PFOS and PFOA from reed belt sediments under current conditions.

Summary: The study reveals the presence of a high abundance of microplastic fibers in the waters of the southern extreme of the Patagonian shelf in the Southwestern Atlantic Ocean. These fibers are predominantly composed of Polyethylene terephthalate in the size range of 0.1 to 0.3 mm. The findings suggest that these microplastic fibers are likely transported to the area via the Antarctic Circumpolar Current, indicating a high risk of microplastic pollution in this sub-Antarctic protected ecosystem.

Summary: The study investigated the adsorption performance of a series of unbranched perfluoralkylacids with different sorbents. The results showed that the anionic exchange sorbent had higher affinity for PFBA than the hydrophobic sorbent, while the adsorption of PFAAs to Al2O3 was weak and chain length independent. The recently developed independent mode (IM) model combining electrostatic and hydrophobic interaction terms accurately predicted the behavior of short chain PFAAs.

Summary: After conducting experiments, it was found that Mediterranean mussels can effectively filter Picochlorum bloom, while Pacific oysters and flat oysters cannot. Additionally, spat oysters have higher filtration efficiency than juveniles and commercial size oysters. The mass mortality of mussels before the Picochlorum bloom could have helped mitigate the spread of the bloom.

Summary: This study investigates network representation in hydrological modelling using field data collected between 2008 and 2018 on the Oued Fez catchment. It found that using the road network as a proxy for the stormwater network improves model performance at both hourly and 5-minute time steps. Additionally, the study provides new hydrological insights for the region, showing the changes in rainfall-runoff dynamics in the urban area from 2008 to 2018.

Summary: The interactions between phytoplankton and bacterioplankton in two contrasting marine coastal ecosystems are significantly affected by chemical contamination, with offshore waters showing a complex network of interactions and lagoon waters showing simpler interactions. Chemical contamination and sediment resuspension lead to changes in the interactions between phytoplankton and bacterioplankton, with distinct effects on nutrient availability and community structure in different ecosystems.

Summary: Aquatic ecosystems under anthropic pressures, such as in the city of Montpellier, face challenges of antimicrobial resistance due to strong demographic pressures. The study utilized a method combining cultural and molecular approaches to explore antimicrobial resistance, revealing a significant increase in cultivable bacterial community, fecal bacteria from human origin, and prevalence of beta-lactamases and extended-spectrum beta-lactamases encoding-genes in urban rivers. Urban rivers in developed areas are shown to contribute to the dissemination of antimicrobial resistance, highlighting the importance of considering these environments as reservoirs for resistant bacteria.

Summary: This study investigates the morphometric properties of the Greater Paris combined sewer system and their impact on Geomorphological Instantaneous Unit Hydrographs (GIUHs). The results show variations in the applicability of scaling laws and their influence on GIUHs. These morphometric properties and GIUHs can be considered as hydrological signatures and are useful for comparison and classification of hydrological responses.
