Summary: Metallophytes are plants that can tolerate extreme metal concentrations in soil. A study on the Dugald River gossan in Australia found that there was no direct relationship between the occurrence of metallophytes and prevailing soil metal concentrations. Crotalaria novae-hollandiae was identified as a strong polymetallic indicator-type metallophyte that can accumulate high concentrations of metals in its leaves.

Summary: Ferroptosis is a regulated form of cell death that has been implicated in metal toxicity. Metals can induce ferroptosis through various mechanisms, including affecting iron metabolism and inducing oxidative stress and lipid peroxidation. While further research is needed to confirm this relationship, ferroptosis may play a significant role in metal toxicity.

Summary: China issued the national childhood lead exposure control guidelines in 2006, with reference values set for high blood lead exposure and lead poisoning. While lead exposure levels have been decreasing in China, lower levels in children's blood may still be associated with neurodevelopmental deficits, prompting a call to lower the reference value based on actual exposure levels to allow for earlier intervention.

Summary: This study investigated the simultaneous removal of Cd2+, Mn2+, and Zn2+ from dilute aqueous solutions using foam separation technique, demonstrating that these metals can be completely removed under specific conditions. Experimental results showed that parameters such as the molar ratio of collector to metals, auxiliary ligand concentration, and nitrogen gas flow rate significantly affect the removal efficiency. The modeled speciation suggested a combination of ion flotation and precipitate flotation for the separation of metals from the bulk solution to the foam phase.

Summary: Manganese (Mn), cadmium (Cd), and lead (Pb) have toxic effects on the immune system, and their independent and combined effects on immune-inflammation responses are unclear. This study found that blood Cd and Mn levels were dose-dependently associated with the systemic immune-inflammation index (SII). High levels of Cd and Mn were associated with an increased risk of elevated SII. However, single Pb exposure and combined Pb exposure with other metals did not show significant effects on SII.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.
