Summary: This study used LA-ICP-MS to investigate the distribution and modes of occurrence of Li, Ga, Nb, and REEs in No. 6 coal from the Haerwusu Mine in the Ordos Basin, China. The majority of Ga and Nb were found to be concentrated in a specific collotelinite layer and had an organic association. Lithium was uniformly distributed in the clay minerals of the collotelinite. Most La and Ce were concentrated in minerals such as monazite, bastnaesite, and lanthanite. Similar characterization methods can be used for trace element analysis in other organic-rich rocks or fine-grained sediments.

Summary: This study investigates the mineral characteristics and geochemical features of No. 26 coal from Junde mine in Hegang coalfield, Heilongjiang province, China. The results show slight enrichment of Cs, Pb, and Zr in the coal, along with the presence of clay minerals, quartz, calcite, siderite, pyrite, monazite, and zircon. The enrichment of elements in the coal is attributed to Late Paleozoic meta-igneous rocks in the Jiamusi block.

Summary: Coal is a complex combination of macerals, minerals, and inorganic elements, along with liquids, gases, and semi-solid organics, all modified by coal metamorphism. Proper coal characterization is essential for academic research and industrial utilization.

Summary: The research focused on the Cretaceous Ge-rich coal seam in the Yimin Coalfield, which hosts the third largest coal-hosted germanium ore deposit in China. Ge concentration in the coal ranges from 28.1 to 135.5 ppm, increasing towards the Ge source direction, and is inversely proportional to ash content and directly proportional to sulfur and volatiles content.

Summary: In this study, the mineralogy and geochemistry of the Pennsylvanian No. 21 coal seam at the Huixiang Mine in the Dengfeng Coalfield, North China were investigated. The coal was found to be semi-anthracite and contained NH4- illite, kaolinite, calcite, and chlorite as the predominant minerals. The coal was slightly enriched with Li, Zr, Nb, Ta, and Th, making it a potential candidate for industrial recovery.

Summary: This study investigates the mineral compositions and concentrations of major and minor element oxides and trace elements in the No. 9 coal from the Xinyuan mine in China. It discusses the occurrence and enrichment mechanisms of critical metal elements such as Li, Ga, Th and REY. The critical metal elements mainly occur in aluminum silicates and were transported to the study area by water, enriching the coal through the combination with clay minerals.

Summary: Sprouts are a potential dietary source of rich minerals and trace elements. Beetroot sprouts are rich in zinc, iron, and magnesium, while onion sprouts are rich in manganese and calcium. Sprouts from the Brassicaceae family are generally richer in calcium, magnesium, and zinc compared to sprouts from the Fabaceae family.

Summary: Fresh vegetables and fruits have always been important sources of nutrients, such as fiber, vitamins, and minerals. Biofortification is a promising strategy to increase the concentration of these compounds in the produce. This review discusses the latest findings on agronomic biofortification, focusing on increasing the concentration of crucial minerals in edible portions of vegetables. The effects on human health and the influence of other compounds were also analyzed to evaluate the advantages and disadvantages of this practice.

Summary: With the increasing focus on recovering critical elements from various coal-related sources, evaluating coal preparation technologies for their role in recovery or rejection of these elements is crucial. Past studies on trace element removal from coal, including those considered hazardous air pollutants in the past, need to be reviewed. The mode of occurrence of these elements in coal plays a significant role in their recovery or rejection during coal preparation processes. Future work should consider element partitioning with coal macerals and comprehensive evaluations of hydrometallurgical principles for element recovery.

Summary: The study examined the daily and within-feed variations of macro- and trace-elements in human milk, finding significant differences in intake estimates when using morning pre-feed samples compared to measured 24-hour intake. Standardized sampling protocols with large sample volumes and multiple collections over 24-hours are recommended to provide a more accurate calculation of infant intake of macro- and trace-elements in human milk.

Summary: Prospecting for trace and rare earth elements is expected to increase in the future as the world adopts sustainable energy and digital technology. This study investigates the distribution of trace elements, especially lithium, in coal beds in Shanxi Province, China. The research finds that trace elements, including lithium, are associated with the inorganic portion of the coal seams.

Summary: Mineral coal extraction in Santa Catarina State in Brazil has caused degradation to the local ecosystem, limiting its use. The uncontrolled disposal of waste and sterile mining with high concentrations of pyrite has led to the formation of acid mine drainage, which poses a threat to water resources, soil, and biodiversity. This study characterizes the heavy metal content in the mining waste and tailings, as well as the presence of fern and lycophyte species in the area. The results show that some fern species demonstrate resistance to degraded and contaminated environments, making them potential candidates for monitoring and environmental recovery.

Summary: A suite of coal samples near a diabase dike in Datong Coalfield, China, was collected and analyzed to investigate the characteristics of thermally altered coal. The study revealed that the 3.6 m dike caused an alteration halo of approximately 2 m in diameter, with thermally altered coals characterized by high vitrinite reflectance and the occurrence of thermally altered organic particles. Cluster analysis classified elements with geochemical associations into different groups, indicating the source of elements and variations in concentrations.

Summary: This study evaluated the concentrations and distribution of various elements in donkey milk. The results showed that the fat fraction of donkey milk contained a small proportion of certain elements, while the casein fraction carried most of the essential elements. Soluble forms of elements were found in whey proteins and the aqueous phase of milk. The findings highlight the element composition of donkey milk and its different fractions.
