Summary: In this study, a type of Ca-Fe-S microparticles was prepared and tested for the reductive immobilization of Cr(VI) in water and soil. The Ca-Fe-S showed higher removal efficiency of Cr(VI) compared to FeSO4 and CaSx in solution. It was also able to effectively sequester Cr(VI) in soil, with a leachable concentration below the regulatory limit after 730 days of curing.

Summary: Chitosan stabilized FeS composite showed high efficiency in remediating high and toxic hexavalent chromium contaminated soil, reducing Cr(VI) by up to 96.6% in 7 days. The addition of CS-FeS composites led to a decrease in soluble Cr and an increase in residual Cr and soil enzyme activity. It also promoted microbial diversity and the growth of microorganisms tolerant to Cr in the soil. These findings demonstrate the potential and promising application of CS-FeS composites for Cr(VI) polluted soil remediation.

Summary: This study evaluated the phytotoxicity to wheat root elongation in different soils across China and examined the biogeochemical processes of added Cr(VI). The results showed that soil properties, such as pH, organic matter, clay, cation exchange capacity, and amorphous Fe oxides, affected the toxicity of Cr. Wheat root elongation was found to be more sensitive to extracted Cr(VI) than Cr(III) after 105 days of incubation. A kinetic model indicated that pH, clay, and amorphous Fe/Al oxides played key roles in the aging and reduction processes of Cr(VI), while organic matter and cation exchange capacity greatly affected the aging process of Cr(III).

Summary: Chitosan/bentonite composites (CSBT) were synthesized and used for the immobilization of chromium in the soil. CSBT could reduce the content of exchangeable and oxidizable forms of chromium, while increasing the content of residual form. The addition of 0.2 g.kg(-1) CSBT had the best effect, with the concentration of exchangeable, reducible and oxidizable forms decreased by 46.74%, 8.15%, and 14.46%, respectively. The amino, carboxyl, and hydroxyl groups of CSBT promoted the conversion of available chromium to residual state in soil, and reduced the bioavailability of chromium in soil.

Summary: The leaching of lateritic soils in Central Sulawesi Island, Indonesia can lead to drainage waters with high concentrations of Cr(VI). A remediation strategy involving FeSO4 solutions effectively removes Cr(VI) from the drainage, but the presence of Mn oxides may cause the oxidative remobilization of Cr(III) and lead to an increase in Cr(VI) concentration downstream. Further improvements to Cr(VI) remediation should focus on preventing the back reaction of Cr(III) with Mn oxides.

Summary: This study investigated the potential use of copper mine tailings as a substitute for Portland cement in concrete construction. The concrete samples were evaluated using various tests, and the results showed that the copper tailings-based concrete had a slightly lower compressive strength compared to the control sample. However, the tests also demonstrated that the heavy metal leaching in the concrete samples was within the acceptable limit. Overall, the cement produced using copper mine tailings can be considered as a feasible alternative to Portland cement in concrete construction.
