Summary: This study proposed a two-step electrochemical process, including electrooxidation (EO) and electrocoagulation (EC), for the tertiary treatment of bio-treated landfill leachate (BTLL). The results showed that EO exhibited high removal efficiency for color and UV254, while EC showed better removal performance for COD and color. In continuous-flow tests, the sequential EO-EC process was more effective than the sequential EC-EO process in removing organic matters and residual chlorine. This study verifies the synergism between EO and EC and provides insights into the removal and degradation performance of organic substances in BTLL during the sequential EO-EC treatment.

Summary: The presence of organic and inorganic contaminants in wastewater discharge has a negative impact on the environment. The electrochemical process shows promise for treating these harmful pollutants from aquatic environments. This review focuses on recent applications of electrochemical processes for removing such contaminants. Electrocoagulation, electrooxidation, and electro-Fenton applications have demonstrated effective performance with high removal rates. However, these processes have drawbacks such as the generation of toxic intermediate metabolites, high energy consumption, and sludge formation. The combination of electrochemical and biological treatment has gained importance in large-scale wastewater pollutant removal, improving removal performance and reducing operational costs.

Summary: This study investigated the sequential treatment of highly resistant landfill leachate using electrocoagulation (EC)/aeration, sulfate radical advanced oxidation process (SR-AOP), and electro-Fenton (EF). The results showed that the sequential application of these processes effectively removed COD, TOC, and ammonia from the leachate, meeting environmental regulations. The current configuration of EC/aeration-PMS/ZVI/UV-EF achieved the best performance and reduced the phytotoxicity of the leachate.

Summary: The effectiveness of a hybrid approach combining electrocoagulation (EC) and adsorption (AD) processes with natural zeolite and/or palygorskite was investigated for treating raw sanitary landfill leachate (SLL). Optimal EC conditions were identified, and the implementation of zeolite as pre- or post-treatment for EC significantly improved ammonium nitrogen (NH4+-N) removal efficiency. Sequential treatment of AD(zeo)-EC showed higher color removal compared to EC-AD(zeo), and integration of AD(pal) into the AD(zeo)-EC system enhanced nitrate nitrogen (NO3--N) removal. The hybrid AD(zeo)-AD(pal)-EC system exhibited high simultaneous removal efficiencies for color, d-COD, NO3--N, and NH4+-N, making it a promising approach for raw landfill leachate treatment.

Summary: This study investigated the transformation and reaction mechanisms of dissolved organic matter (DOM) during electrocoagulation (EC) and persulfate enhanced electrocoagulation (EC/PS) processes for bio-treated landfill leachate (BLL). The results showed that coupling persulfate with EC enhanced the removal efficiency of chemical oxygen demand (COD) and total organic carbon (TOC). The analysis of sediments generated by EC and EC/PS suggested that precipitation was the main contributor to DOM removal during the EC/PS process. These findings help understand the role of persulfate in landfill leachate treatment and reevaluate its advantages and limitations as an oxidant.

Summary: This work investigates the electrochemical treatment of landfill leachates using boron doped diamond (BDD) anodes. The results show that in the absence of ammonia, the electrogenerated chlorine oxidants enhance the removal of chemical oxygen demand but have limited effect on the mineralization of persistent organic pollutants. Furthermore, the study examines the removal of poly- and perfluoroalkyl substances (PFAS) in the leachate, with varying efficiencies depending on the current density used.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
