Summary: A novel sludge-derived biochar (MNBC) was prepared by NaHCO3 activation and KMnO4 modification, which exhibited higher adsorption capacity and faster equilibrium time for Cd(II) compared to pristine biochar. MNBC had a maximum Cd(II) removal efficiency of 90.24% after 5 repeated experiments, and over 98% in different actual water bodies. It showed excellent Cd(II) adsorption performance in fixed bed experiments with a treatment capacity of 450 BV. The Cd(II) removal mechanism involved co-precipitation, complexation, ion exchange, and Cd(II)-pi interaction.

Summary: This study investigated the performance of Fe-Mn-modified biochar for long-term soil remediation and its impact on Cd accumulation in rice plants. The results showed that the biochar effectively decreased the exchangeable Cd fraction in soil and reduced Cd bioaccumulation in rice, especially in the grain, ensuring food safety. Ferromanganese modification and application of biochar can maintain soil redox status, increase root Fe plaques, and enhance the stability of biochar, contributing to its high remediation efficiency over time.

Summary: Corn stover biochar (CSBC) and KOH and KMnO4 modified corn stover biochars (HCSBC and MCSBC) were used to remove oxytetracycline (OTC), and the enhancements of the modifications were investigated. The modifications improved the physical and chemical properties of CSBC, significantly contributing to OTC removal. The removals of OTC by the biochars were a combination of physical and chemical actions, with the chemical action being dominant. The rate-controlling step of OTC removal varied for different biochars, with liquid film diffusion being the dominant mechanism for MCSBC.

Summary: Sequential KMnO4-promoted oxidative pyrolysis and H2O2 oxidation were employed to enhance the adsorption capacities of biochar for methylene blue and tetracycline in an aqueous solution. The co-modified biochar demonstrated significantly improved adsorption capabilities, surpassing single modified biochars and pristine biochar, with the optimal temperature identified as 300 degrees Celsius. The enhanced adsorption capabilities were mainly attributed to the incorporation of MnOx and carboxyl by KMnO4-promoted oxidative decomposition and Mn-catalyzed H2O2 oxidation.

Summary: Biochar modified with potassium hydroxide from Enteromorpha prolifera showed high sorption capacity for sulfamethoxazole, with a maximum capacity of 744 mg g-1. Sorption mechanisms included pore filling, hydrogen bonding, partitioning, 7C-7C stacking, and electrostatic interactions. This study suggests that potassium hydroxide modification can enhance the structure and properties of algal biochar for efficient removal of antibiotics from aqueous solution.

Summary: The widespread use but low recovery rate of agricultural films has led to microplastic accumulation in farmlands, posing a serious threat to the health of the soil ecosystem. This study used earthworms as test organisms to investigate the toxicological effects of low-density polyethylene (LDPE) stress. The results showed that LDPE concentrations had varying effects on oxidative stress, microbial community, and physiological responses in earthworms. The findings provide a theoretical basis for understanding the physiological response of earthworms in polluted environments and offer insights for pollution remediation and ecological security monitoring of soil ecosystems.

Summary: The compound pollutants formed by microplastics and cadmium pose a significant potential threat to the soil-based ecosystem, calling for urgent ecotoxicological studies. However, the lack of suitable test methods and mathematical analysis models has hindered research progress. This study used an orthogonal test design to conduct a ternary combined stress test on earthworms to investigate the effect of microplastics and cadmium. A new model was constructed using an improved factor analysis model and the TOPSIS method to analyze the acute toxic effects on earthworms under the combined stress, providing a basis for early monitoring of contaminated soils and assessments of ecological safety.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
