Summary: The study shows that the PRB-EKSF process mainly relies on electrokinetic transport and dehalogenation for treating contaminated soil, while the adsorption on GAC is not as crucial as expected. In the pilot scale, a significant amount of clopyralid remained in the soil after treatment, and the transport of volatile compounds into the atmosphere was promoted.

Summary: Coconut shell biochars prepared from oxygen-free pyrolysis were used in a permeable reactive barrier (PRB) for electrokinetic remediation (EK) to remove 2,4,6-trichlorophenol (2,4,6-TCP) from soil. The addition of biochar to the PRB significantly increased the removal of 2,4,6-TCP compared to PRB without biochar. The voltage input was found to be the major factor influencing the TCP removal during the EK-PRB process. The optimal conditions for TCP removal were found to be 2 V cm-1 voltage, 700 degrees C pyrolysis temperature, and 40 mg L-1 initial TCP concentration. The biochar played multiple roles in EK remediation, including enhancing electroosmotic flow, adsorbing TCP, and promoting electrochemical degradation. Biochar from high pyrolysis temperature was particularly effective in enhancing electroosmotic flow and pollutant adsorption.

Summary: A novel and environmentally friendly technology for remediating lead-contaminated soil by integrating electrokinetic (EK) remediation and permeable reactive barriers (PRBs) is proposed. The use of cork granules as reactive media in PRBs effectively prevents lead from reaching groundwater, and the pH conditions and electrical field have significant effects on lead sorption and the properties of cork. By using citric acid and reverse polarity strategy, the transportation of lead towards the PRB with cork granules is improved, leading to a near 80% removal of lead from soil after 14 days. This technology shows potential for in situ remediation of lead-contaminated groundwater.

Summary: Electrokinetic remediation combined with a permeable reactive barrier is an effective technique for remediating Cd-contaminated soil. The use of biochar and lanthanum-based biochar composite as PRB filling materials significantly enhanced Cd removal rates in both simulated and real contaminated soils. The mechanism of Cd removal involves electromigration, electroosmotic flow, surface adsorption, and ion exchange.

Summary: The study investigated a potentially new method of PRB-enhanced EKR using an approaching anode (A-EKR + PRB) to help H+ ions migrate quickly to the sample near the cathode. The results showed that the best remediation ability was achieved by treating MSWI fly ash for 16 days at a voltage gradient of 2.5 V/cm, moving the approaching anode after 4 days, and using a PRB containing 10 g of activated carbon. The A-EKR + PRB method reduced HM leaching and total concentrations, while also decreasing environmental risks associated with the remaining HMs.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
