Summary: The study reveals that Baltic Sea sediments record significant loads of Cd, Zn, and Pb, influenced by redox conditions. Concentrations of these metals increased from the early 19th century to the 1970s, then decreased, but are still above pre-industrial levels. Pre-industrial Cd, Zn, and Pb concentrations were higher than those suggested by the Swedish EPA. The reduction in pollution of these metals since the 1980s highlights the importance of environmental governance.

Summary: The study found a geographical pattern in the bioaccumulation of chemical pollutants in zooplankton, with higher exposure in agricultural and industrial areas. Biomarkers MTs and LPO were positively related to pollutant concentration, indicating their suitability for environmental monitoring programs. Zooplankton, as a major component of aquatic food chains, can potentially biomagnify chemical pollutants along higher levels, raising concerns for ecological impacts.

Summary: This study investigated the bulk elemental concentration patterns in the shells of various organisms collected from the brackish waters of the southern Baltic Sea, revealing differences in elemental compositions of shells composed of different crystal lattices. Factors such as crystal lattice properties, organism size classes, biological differences within species, and potential environmental variations between locations were found to play important roles in determining the elemental accumulation in shells. The study also noted that the elemental variability between size-grouped shells differed for each species, with larger size classes generally exhibiting lower elemental concentrations compared to smaller size classes.

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: This study investigated the concentration profiles of trace metals in a sediment core in Beibu Gulf, and found that these metals were mainly naturally sourced and the sediments were not contaminated by trace metals.

Summary: Geochemical analysis plays a crucial role in understanding sediment transport, distribution, provenance, and coastal conditions. Research conducted along the south-eastern Baltic Sea coast in Lithuania revealed different patterns of trace metal distribution in mainland and spit coasts, influenced by coastal processes. Erosion-dominated areas on the mainland coast showed higher trace metal concentrations, while active sediment loading areas on the spit coast had increased concentrations due to northward along-shore transport.

Summary: This study analyzed the mobility of Cr, Cu, Ni, Pb, and Zn in acid sulfate soils in the reverse delta of the Swina River in NE Poland. The results showed that despite the relatively low metal content, these soils could potentially be a source of metal contamination affecting the coastal environment in the southern Baltic Sea region.

Summary: Urban air pollution is a critical problem that threatens human health and causes millions of deaths annually. Trace metals, which can accumulate in living organisms, are significant components of air pollution. Biomonitoring is an effective method for monitoring metal concentrations in urban areas. Platanus orientalis and Ailanthus altissima are suitable plants for biomonitoring due to significant concentration changes according to airborne metals.

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: The analysis of trace metals in sediments of the Laptev and East Siberian Seas showed high concentrations of Cr, Zn, Ni, Cu, As, and Cd, with the increased Cd concentration possibly stemming from the highly productive waters of the Bering Sea. Contamination indices revealed no contamination by Cr, Ni, Cu, Zn, Pb, and Cd at any sampling locations, but slight As enrichment was observed.

Summary: This study aimed to investigate the sources of organic matter (OM) and associated potential toxic metals (PTMs) in an estuary under urbanization. By combining C-N stable isotope analysis and positive matrix factorization, the researchers found correlations between the sources of total sediment metals and the sources of OM-related metals. The study also revealed significant relationships between OM-associated PTMs and organic matter sources. It further deepened the understanding of the coupling between PTMs and sediment organic matter (SOM).

Summary: The study investigated the levels of mercury and its forms in surface sediments of the Baltic Sea, finding that Hg concentrations were highest in industrialized areas and regions affected by historical activities. Labile Hg fractions, mainly organic compounds, were found to be dominant and potentially release into the water column, impacting the trophic chain. Despite reduced Hg emissions, surface sediments remain a significant secondary Hg source in the Baltic Sea ecosystem.

Summary: The study found that the concentrations of Cr, Ni, Zn, and Pb in South China Sea sediments are significantly positively correlated with fine-sized fractions and TOC, while the concentration of As is not positively correlated with other metals. The relatively positive correlations of Cd with various elements suggest it comes from different sources.

Summary: This study analyzed the abundance of microplastic particles in bottom sediments of the Baltic Sea. The content of microplastics varied with water depth, with fibers being the most common type. The distributions of fibers, fragments, and films differed significantly from different types of bottom sediments. An erosion/transition/accumulation pattern for fibers in the Baltic Sea was outlined. The distribution principles of other microplastics remain uncertain.

Summary: Air pollution in industrial areas has become an increasingly significant problem since the 1990s. Tree bark and annual rings have been used as convenient biomonitors for assessing the speciation and transition of pollutants in trees. In this study, Robinia pseudoacacia was found to be the better choice for evaluating atmospheric metal pollution in the Izmit region over the past 30 years.
