Summary: Heavy metal pollution is a global environmental challenge that poses a significant threat to human life. Various methods have been explored to eliminate heavy metal pollutants from the environment, but are constrained by high expenses, processing duration, geological problems, and political issues. The immobilization of metals, phytoextraction, and biological methods have proven practical in treating metal contaminants from the soil.

Summary: Hydroxyapatite-based adsorbent (HAP(PT)) was prepared from phosphate tailings and showed efficient removal of Pb, Cd, and Zn from solution. The adsorption capacity of HAP(PT) was influenced by temperature and pH, and showed high adsorption capacity in mono-metal solutions. Selective adsorption for Pb was observed in the presence of Cd and Zn, while competitive adsorption reduced the adsorption quantity for all metals. The results provided insights into the immobilization mechanisms and potential applications of HAP(PT) in heavy metal removal and phosphate tailings recycling.

Summary: Applications of metal-based nanomaterials for the remediation of heavy metal contaminated environments are of great importance. This study investigated the performance of a metal oxide-based carbon aerogel composite (MO-CAg) for immobilizing Cd and Pb in contaminated soil. The results showed that MO-CAg significantly decreased the leaching of Pb and Cd compared to other materials, and altered the geochemical fractions of these metals. The study also revealed the probable reaction interactions between MO-Cag and heavy metals, suggesting (co)precipitation and reduction-oxidation as the predominant mechanisms of metal stabilization. MO-CAg is a promising material for the remediation of Cd- and Pb-contaminated soils.

Summary: This study explored the activation effect of oxalic acid on bone meal (BM) and developed an oxalic acid-activated bone meal (ABM) for improving heavy metal immobilization efficiency. The results showed that ABM had higher solubility and outperformed BM in terms of immobilizing lead (Pb) and cadmium (Cd). The leaching concentration of Pb from ABM immobilized soils met regulatory limits and was significantly lower than that from BM immobilized soils. After 90 days of curing, ABM also showed better Cd immobilization performance than BM.

Summary: This study investigates the treatment of acid mine drainage (AMD) using waste pyrolysis ash as an adsorbent. The results show that the waste pyrolysis ash has a significant adsorption capacity for metal ions in AMD and can be reused multiple times. The SEM and BET characterization results confirm its potential for metal ion adsorption. The experiments demonstrate that the waste pyrolysis ash effectively treats metal ions in AMD through adsorption, flocculation, and chemical precipitation, providing a low-cost alternative material for water treatment.

Summary: Accumulation of heavy metals in wastewater has become a serious problem for humans. Recent research trends focus not only on the removal efficiency of toxic metal particles, but also on their effective reuse as catalysts. This review discusses the recovery of heavy metals from wastewater, advantages of new capturing systems, and mechanisms for immobilization and rejuvenation of catalysts.

Summary: The study demonstrates that the addition of waste glass effectively strengthens Municipal Solid Waste Incineration (MSWI) fly ash and immobilizes the heavy metals within it. Experimental results show that the immobilization efficiency of chromium increases with the addition of waste glass, while the efficiency of copper, lead, zinc, and cadmium depends on the final pH of the eluant.

Summary: The abandoned Kettara pyrrhotite mine in Morocco is producing acid mine drainage and a cover system made of phosphate wastes was built to prevent pollution. Indigenous plant species were studied based on their tolerance to trace elements in the wastes. Results showed high concentrations of metals in the cover, but studied plants did not hyper-accumulate these metals and were considered suitable for phytostabilization.

Summary: This study compared the effectiveness of different methods in immobilizing lead in soil and found that biochar-supported phosphate showed the best results in reducing the mobility of lead in contaminated soil. The concentration of ammonium nitrate extractable lead in the amended soil was significantly lower, indicating that this method can reduce lead uptake by plants and minimize the potential for water contamination.

Summary: This study presents a multi-analytical investigation of ceramic fragments from the site of Tell el-Far'ah North dating to the Early Bronze II period, identifying them as belonging to a 'metallic ware' industry. The high quality of these ceramic artifacts was achieved through careful selection of materials and firing temperatures between 800 and 900 degrees C. The metallic ware found at Tell el-Far'ah North likely represents a ceramic industry from the central hill country of the Southern Levant.

Summary: In this study, a new composite material was developed by impregnating self-assembling Fmoc-Phe3 peptide hydrogels with in situ prepared silver nanoparticles (AgNPs). Different methodologies for preparing AgNPs were compared. The obtained composites were characterized for their hydrodynamic, structural, and morphological properties, and the antibacterial properties against S. aureus were tested. The results showed that the hydrogel composites containing AgNPs could potentially be used as biomaterials for treating S. aureus-related infections.

Summary: This research aims to differentiate the various sources of azurite exploited in antiquity based on the study of minor and trace elements. Azurite is one of the most important blue pigments in art history, but little research has been done on its provenance. Therefore, it is still not possible to clearly identify the sources of azurite exploited in the past.
