Summary: The study characterizes rare earth elements and trace elements in five genera of deep-sea sponges collected in the North Atlantic. These sponges showed an increased accumulation of trace elements compared to other organisms, possibly influenced by volcanic activity. Additionally, a Light REE enrichment and a negative Ce anomaly were observed in all studied species, providing a baseline for future comparisons.

Summary: The study revealed variations in major and trace element levels in Jordanian honey, with local honey showing higher levels of strontium and total REEs, while imported honey had very low levels of toxic elements, indicating higher safety. Discrimination between imported and local honey would require analysis of a large number of samples (>100) and use of advanced statistical models.

Summary: This study focuses on the trace and rare-earth elements of waters in the Caviahue-Copahue Volcanic Complex. Through sampling and analysis, three groups of waters with distinctive hydrofacies were identified and characterized. The study also compares the different water groups using the patterns of rare-earth elements, allowing for the identification of depletion patterns caused by dilution and precipitation processes.

Summary: In this study, the impact of fish-farm activities on trace elements in the coastal waters off Jeju Island, Korea was investigated. The concentrations of trace elements were higher in the coastal waters and correlated with NH4+. Excess dissolved trace elements in the coastal waters were mainly produced inside fish farms, along with NH4+ and light-REEs. Although some dissolved trace elements were scavenged onto particles in fish-farm rearing waters, these particles would be eventually discharged into the coastal ocean and release the trace elements back into the water columns.

Summary: Rare earth elements are important for modern life but also considered emerging pollutants. There is limited research on these elements in fish, especially in the Caspian Sea. This study aimed to determine the concentrations of rare earth elements in golden grey mullet and compare their bioaccumulation patterns with other toxic elements.

Summary: This study combined trace element and rare earth element measurements in the soil-plant continuum to evaluate element transfer between different compartments. Results showed dissimilar patterns between soil/plant samples and intermediate compartments, indicating heavy rare earth elements were more extractable and transferred to plants compared to light rare earth elements.

Summary: This study presents extensive major and trace element data for the Permian-Triassic boundary at Meishan, China, revealing changes in carbonate lithology, siliciclastic input, diagenesis, and redox conditions. The trace element patterns suggest variations in provenance and weathering processes, with anomalous behavior noted for Ba, Zr, and Zn. Rare earth elements are controlled by the siliciclastic fraction, and Ce and Eu anomalies are not reliable indicators of the redox environment at Meishan.

Summary: Coal fly ash (CFA) is considered an important alternative resource for rare earth elements (REEs) and other critical metals, but concerns about the migration and transformation of harmful trace elements (HTEs) are crucial. Research showed that during the recovery of REEs from CFA activated by NaOH roasting, HTEs were transformed into compounds that were easier to be leached out, providing insights into the behavior of these elements during the recovery process.

Summary: The presence of feldspathic lithologies in lunar meteorites has expanded our knowledge of the lunar crust. However, their origins and relationships to other major crustal lithologies are not fully understood. This study used phase equilibrium modeling to investigate the origins and petrologic connections of lunar crustal lithologies. The results suggest that the compositions of the Mg- and alkali-suites are consistent with partial melting of hybridized sources, while fractional crystallization of KREEP-free Mg-suite melts can produce the characteristics of feldspathic meteoritic lithologies. Overall, the origins of magnesian anorthosites, anorthositic troctolites, and granulites in lunar meteorites remain ambiguous.

Summary: The study in Tehran, Iran analyzed the elemental contents, pollution characteristics, and sources of major, trace, and rare earth elements in road dusts. Results showed significant enrichment of certain elements in road dusts, with traffic-related sources being the prevailing contributor to pollution. Seasonal variation and land use activities were also found to influence the elemental contents in road dusts.

Summary: Municipal wastewater effluent discharges can negatively impact local ecosystems and human health by introducing contaminants to receiving waters. Gadolinium and dissolved rubidium/strontium ratios have been identified as potential conservative tracers for tracking wastewater-sourced pollutants in urbanized freshwater systems, providing a cost-effective alternative to traditional tracers. Studies have shown that these tracers could be valuable tools in investigating wastewater impacts in different geological settings.

Summary: This study investigates the year-round variability of water-soluble trace elements and rare earth elements in size segregated airborne particulate matter samples collected in Ny-angstrom, Svalbard. The findings suggest that the content of wsTE and wsREE, especially in the finest fractions in remote areas, is primarily influenced by long-range transport. Factor analysis and back-trajectories were used to assess the potential of using certain inorganic tracers as indicators of specific transport events or circulation regimes.

Summary: This study examines relicts of granitic Gondwanan basement in the northwest of Central-East Iranian Microcontinent, incorporated into an ophiolitic melange. The findings suggest the presence of an Ordovician anatectic granite formed in a syn-collisional setting, with some metamorphic deformation signatures likely developed in the Devonian. The U-Pb zircon ages from this granite are similar to other Ordovician collision-related magmatic events in the CEIM.

Summary: This study provides important petrologic information on the mantle wedge above an active subduction zone in Southern Colombia. The researchers analyzed a unique suite of rock samples and found evidence of hydration, metasomatism, and partial melting in the mantle wedge. They also observed variations in lithotypes, textures, and mineral abundance, indicating different interactions with melts and fluids. This study sheds light on the complex petrological processes occurring in the mantle wedge and contributes to our understanding of subduction zone dynamics.

Summary: The Hogenakkal complex in India consists of silicate-rich and silicate-poor carbonatites and clinopyroxenites. The formation of carbonatite is influenced by silicate minerals. The carbohydrothermal mineralization in the carbonatites is induced by magma-derived fluids and interactions with the surrounding rocks.

Summary: This study investigates the zircon ages and whole-rock geochemical data of Late Paleozoic magmatic rocks in the Western Yunnan Tethyan belt to identify the origin and mechanism of mantle melting. The results suggest that these magmatic rocks may originate from different mantle domains that were metasomatized by slab-derived fluids and sediment-derived melts.
