Summary: Careful management is required for the high-volume, fine grained tailings from Pb/Zn ore processing. The presence of metalloid elements As and Sb in tailings and leachates can cause regulatory concern due to their toxicity and bioaccumulation potential. The mobility of As and Sb in tailings is controlled by their chemical speciation and associations with mineral phases. By establishing a vegetation cover and promoting oxidation of the tailings, beneficial vegetation cover and a suitable soil-like surface layer can be developed.

Summary: Tungsten (W) is rarely found in natural waters, but can potentially enter the human body through plants, vegetables, and drinking water, potentially causing toxic effects. This study investigated the regional distribution of W in aquatic systems in Sardinia, Italy, and factors affecting its mobility. High concentrations of W were mainly found in mine waters and thermal waters, possibly related to specific chemical conditions.

Summary: Arsenic and antimony exhibited different partitioning behaviors in the sediment-porewater profile system in the tributaries of the Three Gorges Reservoir (TGR). Arsenic showed a lower sediment affinity and higher mobility compared to antimony. The different behaviors could be attributed to the chemical fractions of the trace metals and the pH value of the sediments. The understanding of the transport and fate of arsenic and antimony in the aquatic environment was enhanced through this study.

Summary: A pyro-hydrometallurgical process is developed for selective arsenic removal and recovery of lead and antimony from lead softening slag. The process involves NaOH roasting, water leaching, carbothermic reduction, and HNO3 leaching. The effects of roasting temperature and NaOH dosage on the removal of As, Pb, and Sb are investigated. The proposed process enables the recovery of Pb as antimonial lead and Sb as antimony trioxide.

Summary: This study analyzed the concentrations of antimony (Sb) and other elements, as well as the lead isotopic compositions in PM2.5. The results showed that the Sb concentration in PM2.5 had seasonal variation and was primarily from anthropogenic sources. The correlation between antimony and lead pollution indicated that lead isotopes could be used as a tracer for antimony pollution in air.

Summary: Microorganisms can mediate the transformation of antimony and arsenic, thereby altering their mobility and toxicity. The contamination of antimony and arsenic has different effects on the alpha and beta diversities of protistan communities and their ecological networks. Arsenic contamination has a greater impact on protistan communities compared to antimony contamination.

Summary: A novel method using a calcification transformation-carbothermal reduction process has been developed to treat arsenic alkali residue obtained from antimony smelting. The thermodynamic results show that the calcification transition increases the temperature difference between arsenic and antimony reduction, facilitating their separation. Under the optimal conditions, the arsenic and antimony in the residue achieve calcification rates of 99.67% and 98.74% respectively. The reduction of calcified slag under vacuum effectively separates arsenic and antimony, with a reduction rate of over 99% during the carbothermal reduction process. After reaction and purification by vacuum distillation, purities greater than 99.8% for As and Sb are obtained. Compared with traditional methods, this approach offers better separation and recovery of higher purity arsenic and antimony.

Summary: In this study, a novel aqueous alkaline oxidation method was used to synthesize SbOONa with a cubic structure, and valuable metals Pb and Zn were recovered from the process. This approach not only addresses the high energy consumption and environmental pollution caused by As2O3 dust and hazardous arsenic-alkali residue, but also achieves economically sustainable utilization of antimony resources in the pyrometallurgical process of jamesonite.

Summary: This study explored the contamination and sources of 14 heavy metals in soil at an antimony mining site in Guizhou Province, China, and assessed the risks to both ecosystem and public health. The results showed that antimony, selenium, arsenic, and mercury were heavily polluted and posed significant ecological risks. Industrial activities were the main source of mercury, lead, and arsenic, while nickel, cobalt, gold, and copper originated from both lithogeny and anthropogenic sources. Selenium was of natural origin. This research is important for ensuring soil safety and protecting local people's health.

Summary: In this study, water and sediment samples were collected from the area affected by non-ferrous metal mining activities to analyze mercury (Hg) residues and evaluate the ecological and health risks. The enrichment of Hg in sediments was observed in the Zijiang River, especially in the upstream and midstream regions. Two potential Hg sources were identified in the basin. The ecological risk of Hg was more significant in the Zijiang River, and the health risk values were lower than the USEPA's guideline value for different populations.

Summary: This study aims to determine the concentrations and spatial distributions of toxic elements in soils of southern Louisiana and assess the pollution status. The results show that the concentrations of toxic elements in soils are generally low, but some samples exceed the guideline limits. Additionally, hotspots of pollution were identified in certain areas.

Summary: The study found that the levels of PAHs and heavy metals in the muscle of warty crabs were low and safe for human consumption, except for arsenic which exceeded the acceptable level of cancer risk. This highlights the potential health risks posed by consuming these crustaceans contaminated with arsenic, emphasizing the importance of monitoring pollutants in crabs and seafood to ensure food safety for consumers.

Summary: This study analyzed the occurrence, distribution, migration, and influencing factors of antimony (Sb) in the Zijiang River. The study found that mining and smelting were the main sources of Sb in the river. The concentration of Sb showed a decreasing trend from the tributaries to the mainstream, and the retention and accumulation of sediments led to the secondary release of Sb.
