Summary: The present study designed a phosphogypsum slag-based cementitious material (PS) and investigated its potential use for solidifying/stabilizing lead-contaminated soils. The physicochemical properties, performance, and mechanisms of lead stabilization in soil were studied using various methods. The results showed that the PS solidified body had acceptable compressive strength for backfill treatments or roadbed materials. The leaching concentrations of lead were within the safety limit specified in Chinese standard, indicating the potential for safe disposal and reuse of PS stabilized soil.

Summary: Anaerobic oxidation of methane-microbial fuel cells (A-AOM-MFC and F-AOM-MFC) with acetate-acclimatizing or formate-acclimatizing electroactive culture were studied. A-AOM-MFC produced a higher voltage and F-AOM-MFC started up faster due to different mechanisms of methane-electrogen caused by different microbial alliances. In A-AOM-MFC, acetoclastic methanogens converted methane to acetate and carried out direct interspecific electron transfer (DIET) with Geobacter-predominated electricigens. In F-AOM-MFC, intermediate-dependent extracellular electron transfer (EET) occurred between hydro-methanogens and electricigens, with faster production of formate-dominant intermediates.

Summary: The composite Fe3O4 nanoparticles (DQ@Fe3O4) based on natural clay (dolomite and quartz) have been extensively studied for the removal of heavy metal ion contaminants from residual waters. Optimized experimental parameters showed that DQ@Fe3O4 achieved maximum removals of 95.02% for Pb2+ and 86.89% for Cd2+ at specific conditions. Characterization techniques confirmed the co-precipitation of dolomite-quartz by Fe3O4 nanoparticles. Kinetic and equilibrium studies further supported the suitability of pseudo-second-order kinetic and Langmuir isotherm models for metal binding onto the DQ@Fe3O4 surface. Thermodynamic and Monte Carlo simulation data demonstrated the spontaneity and effectiveness of the adsorption process. In summary, DQ@Fe3O4 can be considered as a cost-effective adsorbent with great potential for wastewater treatment.

Summary: The endophytic Basidiomycete Sporobolomyces ruberrimus protects its host Arabidopsis arenosa against metal toxicity by fine-tuning plant metal homeostasis and precipitating Fe in the medium. The fungus transforms iron into amorphous (oxy)hydroxides and phosphates, immobilizing them as a precipitate and changing Fe behavior in the medium. Free Fe ions can also be complexed by biomolecules produced by the fungus such as lipids, proteins, or biosynthesized redox-active molecules.

Summary: This study constructed the L. hexandra constructed wetland-microbial fuel cell (CW-MFC) system to treat Cr (VI) wastewater and determined the effects of different dissolved oxygen (DO) concentrations on power generation, pollutant removal, and Cr (VI) reduction. Cathode aeration promoted the voltage output and pollutant removal of the system, and increased DO concentration improved the absorption of heavy metal Cr by the substrate and L. hexandra, promoting the transformation from Cr (VI) to Cr (III). The research results can provide a reference for the subsequent CW-MFC treatment of actual Cr-containing wastewater.

Summary: Submerged macrophytes and their epiphytic biofilms play important roles in metal transport and transformation in aquatic environments. This study collected samples from the moat in the industrial area of Hangzhou to analyze the bacterial community structure and the contribution of epiphytic biofilms to heavy metal accumulation. The results showed that the bacterial community structure was significantly influenced by TN concentrations and that the epiphytic biofilms were dominated by heavy metal pollutant-resistant bacteria such as Aeromonas, Acinetobacter, and Pseudomonas. The study also found that the epiphytic biofilms had higher Cr accumulation compared to leaves, while leaves had higher Cu accumulation than the biofilms. The findings suggest that the epiphytic biofilms can effectively accumulate metals, particularly Cr, and can be a potential method for metal remediation.
