Summary: The chemistry of toxic metalloids and metals in soil differs, making their simultaneous removal challenging. In this study, a novel remediation method was used to wash soil contaminated with arsenic (As), lead (Pb), zinc (Zn), and cadmium (Cd) using oxalic acid, Na-dithionite, and EDTA solution. Toxic elements were successfully removed from the washing solution by alkalinisation with CaO. The remediation was most effective for As, reducing its accessibility and mobility significantly. The remediation did not affect the soil's functioning and resulted in increased biomass production in Brassica napus, with reduced accumulation of metals.

Summary: Sediments play a crucial role in the storage of heavy metals in river and lake waters, and their chemical makeup influences the movement of these elements within the ecosystem. Therefore, it is essential to remediate polluted sediments for the overall health of the ecological environment. This study proposes a simple method for extracting heavy metals from contaminated sediment using horizontal electroosmosis, and investigates the effect of different washing reagents and operational parameters. Citric acid and EDTA were found to be the most effective in removing Cd and Pb, respectively. After 13 days of electrokinetic washing, the removal ratio of Cd by citric acid was 77.0%, and that of Pb by EDTA was 88.3%. The decrease in various fractions of the heavy metals upon their removal from the polluted sediment was observed.

Summary: In this study, a combination of electrokinetic and chemical immobilization was used to remediate Cd and Pb polluted river sediments. The immobilization ratios for Cd and Pb were achieved by adjusting the concentrations of the immobilization reagents and the applied voltage. The enhancement effect of the electric field is mainly due to the increased contact between the immobilization reagents and the heavy metals.

Summary: Heavy metal pollution, especially the Pb concentration in sediment, has a significant impact on aquatic ecosystems. The variations in heavy metal concentrations in sediments are linked to changes in sediment and tadpoles' gut microbiomes. Pb leads to a trade-off between the proportions of Burkholderiales and Verrucomicrobiae in sediment microbiota and affects methane, sulfide, and nitrate metabolisms. Tadpoles with high sediment Pb content have a low abundance of gut aerobic bacteria and a large relative gut weight.

Summary: Utilizing hyperaccumulators, such as ryegrass, along with the addition of BC and FA, can improve the efficiency of phytoremediation for multiple heavy metals contaminated sediments. BC and FA increased the bioavailability of Cd and Zn, while decreasing the bioavailability of Pb in the sediments, therefore promoting their extraction by ryegrass. The results suggest the potential of BC and FA in assisting the phytoremediation of heavy metals in sediments.

Summary: Deposits of contaminated wood fiber waste have been found in boreal countries and in-situ isolation capping has been proposed as a remediation solution. However, knowledge about the performance of such caps on soft, gaseous organic rich sediment is scarce. This study investigated the effectiveness of in-situ capping on limiting POPs fluxes from contaminated fibrous sediments that produce gas.

Summary: The coastal zone of Bangladesh is facing serious threat of heavy metal pollution, with previous studies finding that concentrations of various heavy metals in water, sediment, and fish were above permissible limits. Sediments serve as the ultimate sink for high concentrations of heavy metals, and bottom-dwelling organisms have higher levels of heavy metals.

Summary: Anthropogenic activities can lead to contamination of heavy metals in the environment, especially in sediment. The remediation of contaminated sediment is a global challenge, and the ecological risk and ecotoxicity of the restored sediment need to be evaluated. Our study found that microbial bioleaching effectively reduced the bioavailable fraction of Cu, Ni, and Zn in contaminated sediment, reducing the ecological risk and ecotoxicity.

Summary: This study applied a partially water-soluble solvent (EAEW) for remediating complexly contaminated soils by TPH, HMs, and BaP, with optimized conditions and high removal efficiencies demonstrated in laboratory tests and pilot-scale system. The addition of HCl to the EAEW solvent was crucial for highly removing multi-pollutants, and the solvent could be regenerated and reused for multiple cycles. The EAEW solvent, with proven effectiveness, high recovery, and environmental friendly property, showed a high potential for feasible on-site application for multi-polluted soil remediation.

Summary: This paper introduces the role of fulvic acid (FA) in controlling the environmental geochemical behavior of metals, and reviews the progress of research on metal remediation by FA through physicochemical and bioremediation methods. FA can control the biotoxicity and migration ability of metals through adsorption and redox reactions. Factors such as concentration, molecular weight, source, pH, temperature, metal ion concentrations, and competing components in sediment environments affect the remediation ability of FA. The challenges and future research directions of FA in metals ecological remediation are also discussed.

Summary: This study demonstrates the efficient removal of heavy metals from contaminated soil using biosurfactant surfactin through a micellar-enhanced ultrafiltration (MEUF) process. The surfactin can bind heavy metals through electrostatic interactions and then be rejected by the ultrafiltration membranes, resulting in over 98% removal of metals.

Summary: Intensive anthropogenic activities, specifically, industrial and agricultural production, have led to the accumulation of heavy metals in lake sediment, posing threats to aquatic ecosystems and human health. Evaluating the potential ecological risk of heavy metals in lake sediment is crucial for effective lake management. However, large-scale risk evaluations of heavy metal pollution in lake sediment are lacking in densely populated countries like China. This study compiled data from 190 lakes across five geographic zones in China and evaluated the ecological risk and sources of heavy metals in lake sediment, providing valuable insights for policy formulation and lake restoration.

Summary: This study focused on basin-scale factors of metal concentrations in river sediments. The results showed that geology, dams, and land cover were the most important factors, while rock characteristics and reservoir drainage area also played significant roles. Vegetation indices were more important than land cover types. Different metals had varied responses to basin-scale factors. The study demonstrates the importance of understanding large-scale factors in metal pollution research and policymaking.

Summary: The study conducted two laboratory tests to verify the suitability of Italian commercial biochar as an adsorbing material for arsenic in groundwater. While the results aligned with previous literature, they also showed that using a large amount of biochar does not necessarily improve efficiency. Additionally, factors such as the origin and grain size of the biochar can affect the efficiency of adsorption.
