Summary: This study investigates the background levels of heavy metals in the Bohai Sea sediments and assesses the ecological risks using sediment core, 2-sigma outlier, and regression methods. The results show significant disparities between the ecological risks calculated by the regression method and the sediment core/2-sigma methods, suggesting the regression method is not suitable for the complex sources in the Bohai Sea. However, the sediment core method indicates moderate ecological risks, with most heavy metals having negligible contamination except for Hg and Cd.

Summary: This study examines the contamination, accumulation, and ecological risk of five trace metals in sediments of an urbanized beach in Morocco. The results show that, overall, the sediments were within the acceptable limits, indicating low contamination and low ecological risk. However, there was an increase in Cd levels in 2019 due to anthropogenic activities, leading to moderate pollution and moderate ecological risk. It is recommended to reduce avoidable human activities to mitigate metal pollution in the study area.

Summary: This study assessed the concentrations and distribution of seven metals along the Spanish Mediterranean coast. The results showed different pollution patterns in the sediments of the northern and southern water bodies. Most of the metal contents along the coast do not pose a potential risk to aquatic organisms. Mussels were found to have higher metal content than clams and are better indicator organisms for this type of pollution.

Summary: Trace metals in sediments from the Chester River were investigated to understand their distributions and potential sources. The concentrations of lead, arsenic, nickel, chromium, and copper exceeded sediment toxicity guidelines in a significant proportion of samples. Enrichment factors for cadmium, silver, lead, arsenic, and zinc were elevated above natural background levels. Nickel, copper, zinc, and cadmium showed significant differences in enrichment factors between different segments of the river. Cadmium and arsenic enrichments were most likely from the application of fertilizers in the watershed, while active marinas were identified as important sources of metal enrichment, especially for copper.

Summary: The concentrations of trace metals (Cu, Pb, Zn, Cr, Cd, As, Hg, Ni, Li, and Co) in sediment cores were studied to determine background levels, assess deposition patterns, and examine contamination in Laizhou Bay, China. Anthropogenic enrichment was observed for Pb, Cd, and Hg, which can be traced back to human activities since 7 thousand years ago. Trace metal concentrations during the 10-7 thousand years ago phase were considered as background levels. Analysis showed that the metals were mainly from natural sources, and contamination was observed for Pb, Cd, and Hg during the 7-0 thousand years ago period.

Summary: The study investigated the concentrations of eight trace elements in Posidonia oceanica leaf blades and sediments sampled from 23 stations along the Turkish-Mediterranean Sea coast, revealing significant distribution differences among sampling stations. While most of the trace element concentrations varied significantly among stations without a consistent trend, Zn, Cd, Cu, and Pb in the sediment were determined as non-polluted based on sediment quality guidelines, with some stations showing moderate to heavy pollution for Cr, Ni, and As. The findings suggest that the western sites of the study area are heavily exposed to trace elements due to human activities, with significant positive correlations detected between anthropogenic and natural sourced trace elements.

Summary: This study assessed the pollution of microplastics (MPs) in surface sediments of urban, aquaculture, and environmental preservation sites in South Korea, and investigated the historical trend using age-dated core sediments. The abundance of MPs ranked in the order of urban, aquaculture, and environmental preservation sites. An increase in MP pollution and polymer types was observed from bottom to top of cores, and the historical trends of MP pollution reflected local influences. The characteristics of MPs are determined by human activities, and MP pollution should be addressed according to the characteristics of each site.

Summary: This study is the first to investigate the presence of microplastics in sediment, water, and benthic organisms (foraminifera) of a marine cave in the Gulf of Orosei, Italy. The microplastics identified in the samples consisted mainly of PVC and polyethylene fragments and fibers. The source of these microplastics was likely the sea rather than seasonal freshwater supplies. Furthermore, the study found that foraminifera collected and incorporated microplastic items into their shells. This study provides evidence that marine caves can act as collectors of microplastics and highlight the potential impact on protists.

Summary: Submarine canyons are important pathways for the transport of particulate matter and contaminants from the shelf to the deep sea. This study analyzed sediment cores from the Gulf of Palermo continental margin to investigate the historical record of trace metal contamination. The results showed that trace metal contamination increased until the 1970s and 1980s, associated with urbanization and industrial activities. However, the expansion of bottom trawling fleets in the region since the 1970s and 1980s has led to resuspended sediment and increased sediment accumulation rates, diluting and reducing the trace metal contamination levels.

Summary: Alongshore changes in shorelines along sandy beaches result from variations in wave conditions and nearshore morphology, which create large-scale undulations called megacusps. This study investigates the dynamics of megacusps and their coupling with crescentic bars using a long-term dataset at the beach of Castelldefels. The results show that megacusps are strongly linked to the presence of crescentic bars, and the coupling pattern depends on wave height and angle.

Summary: The researchers investigated four adjacent vegetated coastal habitats in Cadiz Bay, South Spain, and found that subtidal seagrass Cymodocea nodosa had the highest organic carbon and total nitrogen stocks, followed by upper intertidal salt marsh Sporobolus maritimus, subtidal rhizophytic macroalgae Caulerpa prolifera, and lower intertidal seagrass Zostera noltei. They also observed that sedimentation and organic carbon burial rates increased with elevation. Overall, this study emphasizes the importance of using habitat-specific carbon and nitrogen stocks and burial rates to predict the sequestration capacity of vegetated coastal habitats at the seascape level.

Summary: A simulation was conducted to study sediment transport, erosion and deposition in the Gulf of Lion. The simulation compared simulated and observed data to assess reliability. The results showed sediment accumulation near the Rhone River mouth, accretion along the mid-shelf mud belt, and the impact of dense shelf water cascading on sediment resuspension and erosion. The study found an unbalanced sedimentary system with a deficit mainly over the inner shelf due to reduced inputs from the Rhone River.

Summary: This study analyzed sediment from Cienfuegos Bay, Cuba to examine the occurrence of organic pollutants from 1990 to 2015. The results showed the presence of regulated contaminants such as PCBs, OCPs, and PBDEs, with a decline in PCB contamination since 2007. Emerging contaminants, including PAEs, OPEs, and aHFRs, showed sharp increases, possibly due to the growing global usage of flame retardants and plasticizer additives. Local sources, such as a plastic recycling plant and urban waste outfalls, may contribute to these trends. Further research is needed to understand the influx of these emerging contaminants.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
