Summary: Conversion of highly available soil Pb to plumbojarosite (PLJ) has been found to decrease Pb relative bioavailability, but there is limited information on interactions with other elements when contaminated soil is ingested. Results show that RBA of treated soils was less than 1%, with PLJ phases transiting the GIT with little absorption and Pb associated with organics predominantly found in the cecum, indicating insoluble PLJ transits to feces. Understanding interactions during GIT transit complements knowledge of elemental interactions with Pb at higher biological organization levels.

Summary: Careful management is required for the high-volume, fine grained tailings from Pb/Zn ore processing. The presence of metalloid elements As and Sb in tailings and leachates can cause regulatory concern due to their toxicity and bioaccumulation potential. The mobility of As and Sb in tailings is controlled by their chemical speciation and associations with mineral phases. By establishing a vegetation cover and promoting oxidation of the tailings, beneficial vegetation cover and a suitable soil-like surface layer can be developed.

Summary: In this study, MnOx nanocatalysts with abundant oxygen vacancies were prepared using reverse-micelle as a template and endowed with an amphiphilic surface through post-modification. These catalysts were utilized to formulate Pickering emulsion and create compartmentalized droplet microreactors for the epoxidation of styrene. The oxygen defects on MnOx improved the chemisorption of t-butylhydroperoxide and facilitated the formation of superoxide radicals for the synthesis of styrene oxide. The compartmentalization effects from Pickering emulsion droplets enhanced the radical reaction path, resulting in higher selectivity and catalytic efficiency.

Summary: Increasing metal atom loading on single-atom catalysts does not necessarily improve their activation performance on peroxydisulfate (PDS). This study synthesized dual-atom catalysts (Fe0.4Cu0.6-N-C) using a one-pot method and demonstrated that the synergism between Fe and Cu atoms enhanced the adsorption of PDS and served as active centers for PDS activation. The findings highlight the potential of the dual Fe-Cu sites for pollutant degradation through electron-transfer pathways.

Summary: This study successfully optimized the preparation process of ball-milled biochar (BMBC) through response surface methodology and Box-Behnken design. The results showed that the key factors affecting Cd removal by BMBC were milling speed, grinding time, and ball-to-powder mass ratio, with the optimal parameters found to be milling time = 16 h, speed = 448 rpm, and ball to powder mass ratio = 1.5:100. BMBC exhibited significantly larger specific surface area and pore volume compared to biochar, and had a higher adsorption capacity for Cd2+. Precipitation and complexation were identified as the main mechanisms for Cd adsorption. Therefore, BMBC is a promising and effective adsorbent for Cd removal.

Summary: This study investigated the effect of straw returning and nitrogen fertilizer application on hydroxyl radical formation in the surface water of paddy fields. The results showed that straw returning decreased hydroxyl radical formation, while nitrogen fertilizer application increased it. Correlation analysis revealed that dissolved organic matter and NO3- affected hydroxyl radical production in the early stage, whereas NO2- had a significant effect in the later stage. The decrease in NO3- and NO2- content after straw return may contribute to the lower hydroxyl radical formation in the amended paddy soil.

Summary: High-performance, environmentally friendly, and low-cost single-atom catalysts (SACs) show great potential in the degradation of organic contaminants using peroxymonosulfate (PMS). A novel manganese single-atom catalyst (SPBC-700N) was successfully synthesized using Phytolacca americana as a precursor through one-step pyrolysis. The SPBC-700N exhibited extraordinary catalytic activity for PMS activation, leading to over 90% removal of chloroquine phosphate (CQP) within 30 minutes. The excellent catalytic performance of the Mn SAC/PMS system is attributed to the maximized utilization of manganese atoms and the synergistic effect with neighboring pyrrolic nitrogen sites.

Summary: Regulating the density of metal single atoms and exploring their interaction can enhance the performance of single-atom catalysts. In this study, copper single-atom catalysts were synthesized and it was found that the catalytic activity is proportional to the density of copper single atoms. Mechanistic studies revealed that the interactions among neighboring single-atom moieties in high-density copper single-atom catalysts alter the electronic structures, leading to improved adsorption and suppressing side reactions. The ultrahigh-density copper single-atom catalyst exhibited significantly higher activity and utilization efficiency compared to previous reports, providing a practical catalyst for phenol production.

Summary: This study investigated the absorption and transportation of nano-biochar (N-BC) particles by wheat and Chinese cabbage plants. The results showed that N-BC particles were readily absorbed by the plants through their root systems and transported to aboveground tissues. Stable isotope analysis confirmed the uptake and transportation of N-BC, with elevated isotopic values observed in the plant tissues exposed to 13C-N-BC. notably, significant accumulation of N-BC was found in the edible parts of Chinese cabbage, raising concerns about its potential entry into the food chain and associated health risks. Further research is necessary to explore the specific pathways and modes of N-BC uptake and transport in plants, and monitoring its presence and potential impact on the food chain is crucial for ensuring food security and safeguarding human health.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
