Summary: Trace elements are pollutants that can be dispersed in the environment, causing adverse effects to ecosystems and human health. They can accumulate in higher trophic levels, including humans, and may pose a risk even at natural concentrations. Periodic monitoring of marine environments is recommended to minimize human health risks and mitigate detrimental effects to biota.

Summary: Intertidal sediments are a significant reservoir of trace metals from human activities and natural weathering. Quantifying trace metal contamination is challenging due to the lack of geochemical background levels and sediment heterogeneity. In this study, dynamic background functions were established to distinguish natural and anthropogenic inputs in the Daliao River estuary. The results showed that Zn and Cd were contaminated by human activities, while other trace metals (Cr, Ni, Cu, and Pb) were influenced by variations in geological background levels.

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 investigates the trace element concentrations in surface sediment samples collected in the Antarctic Peninsula. The results show lower concentrations of Fe, Mn, Co, V, Zn in Hope Bay, while moderate to significant enrichment in Cu, As, Cd in the Bransfield Strait and around King George Island. Twelve stations present a moderate ecological risk. The results suggest a natural origin for the element enrichment, possibly related to volcanism and the geology of the area.

Summary: To study the ecological risks of trace metals in sediments and their impact on benthic organisms, 12 trace metals were analyzed and macrobenthos were identified in sediments collected from the south coast of Zhejiang province in the East China Sea. The concentrations of most trace metals were high in the estuary, except for Ba and Sr. The concentration of Cd slightly exceeded the coastal background, indicating potential ecological risk. Methods based on sediment quality guidelines were found to be more intuitive in assessing ecological risk compared to those based on background values (PN, PLI, RI). Significant correlations were observed between ecological risks and benthos density and biomass, suggesting the negative impact of high concentrations of trace metals on macrobenthic survival in sediments.

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: Non-targeted analysis (NTA) is a rapidly evolving set of mass spectrometry techniques aimed at characterizing complex samples' chemical composition, identifying unknown compounds, and classifying samples. Recent advances are due to improved instrumentation and accessible data analysis tools, with a growing need for community-wide method reporting guidelines. This has led to the formation of the Benchmarking and Publications for Non-Targeted Analysis Working Group (BP4NTA) to address challenges and establish consensus in NTA-related terms and reporting practices.

Summary: Per- and polyfluoroalkyl substances (PFAS) are anthropogenic pollutants that are widely present in surface and drinking water. Non-targeted analysis (NTA) methods based on high-resolution mass spectrometry (HRMS) have been developed to comprehensively characterize PFAS in environmental samples. This study compared NTA workflows using online solid phase extraction-liquid chromatography high resolution mass spectrometry (online SPE-LC-HRMS) in screening PFAS in drinking and surface waters in Southern Florida. Tap water showed the highest number of PFAS features, indicating poor removal or breakdown of PFAS precursors. Furthermore, a semi-quantitation method for NTA (qNTA) was proposed for concentration estimation. NTA plays a crucial role in identifying and prioritizing non-traditionally monitored PFAS to better understand their toxicological and environmental impact.

Summary: In this study, the effects of physicochemical properties of Florida topsoil and Hanford site sediment as well as the influence of immobilizers on PFOS sorption were investigated. Organic matter was found to play a key role in PFOS retention, while food waste compost had no impact on PFOS uptake. However, activated charcoal amendment significantly enhanced PFOS sorption in both soils by increasing the soil/water partitioning coefficients.
