Summary: In this study, unique layered Fe(III)-Cr(III) oxides were formed during the Cr(VI) removal by sulfate green rust (GRSO4). The layered structure of GRSO4 remained intact after fast reduction of Cr(VI). Further reduction of Fe(III) to Fe(II) using sodium dithionite resulted in stable Fe(II)/Fe(III) cycle in the hexagonal plates. The study observed better crystallinity at higher Fe(III) reduction rate and confirmed the layered metal oxide structure. Multiple treatment cycles showed increased Cr(III) loading on the layered Fe(III)-Cr(III) oxides. The study provides new evidence and insights for formulating strategies to eliminate Cr(VI) or related heavy metals.

Summary: In this study, a combined approach of chemical reduction and microbial stabilization was investigated for the remediation of Cr(VI) contaminated soil. The combination of ferrous sulfate and biogas solid residue effectively converted Cr(VI) into Cr(III), reducing the residual Cr(VI) content to a level well below the screening value for soil contamination. The treatment also eliminated the phytotoxicity of the soil and caused significant changes in the microbial community.

Summary: This study developed a synergistic system of P. oxalicum SL2-nZVI for Cr(VI) remediation, which effectively removed Cr(VI) mainly through extracellular nonenzymatic reduction. P. oxalicum SL2 exhibited iron precipitate solubilization and Fe(II) regeneration capabilities, and iron ions generated by nZVI also stimulated Cr(VI) reduction by organic acids secreted by P. oxalicum SL2. Overall, the P. oxalicum SL2-nZVI synergistic system shows promise for regenerating Fe(II) while reducing Cr(VI).

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 work presents a novel chitosan coated magnetite/rhodochrosite composites that efficiently remove Cr(VI) from aqueous solution. The characterization results show that the chitosan carbon firmly coats the thermally modified rhodochrosite and magnetite, and the composites prepared at 900 degrees C have improved specific surface area. The removal of Cr(VI) is pH dependent, and the composites exhibit better removal capacity than natural magnetite, rhodochrosite, and Ch-BC.

Summary: A novel, inexpensive and eco-friendly composite material (Fe@N-L-GM) consisting of aminated lignin, geopolymer, and Fe nanoparticles was synthesized and used for the simultaneous removal of Cr(VI) and NAP in wastewater. The material showed excellent adsorption capacity for Cr(VI) and high degradation efficiency for NAP. The adsorbed Cr(VI) was transformed into less toxic Cr(III) through reduction by electron donors, while ·OH radicals played a crucial role in mediating NAP degradation. The presence of NAP enhanced the removal rate of Cr(VI), with phenol as the main substance promoting Cr(VI) reduction. This work provides a new material and theoretical foundation for the simultaneous removal of heavy metals and persistent organic pollutants.

Summary: The study investigates the role of external sodium acetate (SA) in improving Cr(VI) reduction and stabilization in Cr(VI)-spiked soils. Batch experiments showed that the addition of SA resulted in a decline in soil Cr(VI) content and an increase in the relative abundances of Cr(VI)-reducing microorganisms. Redundancy analysis indicated that pH and SA were the predominant factors affecting the microbial community. Functional prediction suggested that the addition of SA had a positive effect on the metabolism of key substances involved in Cr(VI) microbial reduction.

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 intensification of aquaculture production causes various stresses in fish, which are exacerbated by climate change. Therefore, it is crucial to find a comprehensive strategy to alleviate these stresses. This study investigated the removal of nitrogenous metabolites from aquaponics water using medicinal and aromatic plants (MAPs). The results showed that products derived from mint, banana stem, and aloe vera effectively reduced ammonia and nitrite levels. Mint also exhibited antibacterial properties and improved fish growth and immune response. This study suggests the potential application of mint in aquaculture management.

Summary: The release of contaminants of environmental concern including heavy metals and metalloids, and contaminants of emerging concern including organic micropollutants from various sources, is a global threat. Conventional methods for managing mixed contaminants of low concentrations are not economically viable, hence low-cost materials need to be developed for efficient removal of these contaminants. Biosorption, using biomass or biopolymers derived from plants or animals, is an environmentally friendly and energy-efficient approach for decontamination by utilizing the inherent biological mechanisms. This review highlights the relevance of different chemical constituents and bioactives in biosorbents derived from agricultural production and animal production for sequestering and bioremediation of contaminants of environmental and emerging concern (CEECs).
