Summary: This study explains the accumulation of different PFAS in water bodies, showing a wide range of PFAS concentrations and varying levels of bioaccumulation in fish and water biota. Recent research has focused on removing PFAS from aqueous solutions, with advanced oxidation processes (AOPs) being a promising technique. Developing novel, efficient, cost-effective, and sustainable AOPs for PFAS degradation in water treatment systems is critical.

Summary: This paper systematically reviews and discusses the effect of ozonation on the removal of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in aqueous solutions. The results show that ozonation is more effective in removing resistant bacteria than their respective genes, but there is no definite conclusion about the superiority of ozone alone or in a hybrid form. The study also evaluates the regrowth after ozonation and the influence of operational parameters on degradation efficiency.

Summary: The petroleum industry is rapidly growing, leading to increased environmental concerns about wastewater treatment. Advanced oxidation processes (AOP) have been applied for treating petroleum wastewater due to the limitations of conventional treatment methods. Different AOP techniques have shown varying degrees of efficiency in treating petroleum wastewater based on the contaminants present and operating conditions. Ongoing research focuses on further improving the AOP treatment methods for petroleum wastewater.

Summary: Advanced oxidation processes have been widely studied for their effectiveness in removing biorefractory pollutants from wastewater. However, there is a lack of suitable methods to compare the performance of different AOPs. This paper proposes a novel criterion, the accumulated oxygen-equivalent chemical-oxidation dose (AOCD), to systematically compare diverse AOPs.

Summary: This study analyzed 70 samples of organic fertilizers for veterinary antibiotics. The results showed the presence of doxycycline, oxytetracycline, tetracycline, lincomycin, tiamulin, and enrofloxacin in the tested samples. Doxycycline was found to be the dominant compound, with the highest concentration of 175 mg/kg in pig manure. The study also found that the application of organic fertilizers, especially animal feces, could be the primary source of antibiotics. Risk assessment based on a risk quotient indicated that the antibiotic concentrations in fertilizers could pose a threat to soil microorganisms.

Summary: This study investigates the treatment of oxytetracycline (OTC) aqueous solutions, a member of the tetracycline group (TCs), using different electrochemical processes. Electrogenerated active chlorine (EAC) showed the fastest degradation of OTC, while direct anodic oxidation (AO) achieved the highest removal of total organic carbon (TOC). Electro-Fenton (EF) presented intermediate removals of OTC and TOC and consumed the least energy.

Summary: The widespread use of antibiotics has resulted in increasing antibiotic contamination of shallow groundwater. Oxytetracycline, the most widely used tetracycline antibiotic, has drawn attention from researchers due to its stable molecular structure and difficulty in degradation. In order to remediate oxytetracycline pollution in groundwater, nano-calcium peroxide (nCaO(2)) and ozone (O-3) are used to enhance the degradation of oxytetracycline in groundwater circulation well (GCW). A three-dimensional sand box test device is designed to evaluate the efficiency of circulation wells strengthened by different oxidants. The results demonstrate that enhanced GCW treatment using nCaO(2) and O-3 has the potential to remove oxytetracycline in groundwater environments.

Summary: Fenton oxidation with a heterogeneous hematite catalyst in a fixed bed reactor has been studied for water disinfection. The hematite catalyst exhibits good chemical stability and catalytic activity in decomposing H2O2, inactivating E. coli bacteria, and degrading oxytetracycline. The efficiency of bacterial inactivation and oxytetracycline removal increases with the concentration of H2O2.

Summary: Boric acid modified Bi2Fe4O9 (H3BO3@Bi2Fe4O9) materials were prepared by surface H3BO3 treatment on Bi2Fe4O9 through mechanical ball milling method. The study found that this modification process introduced more oxygen vacancies on the surface of Bi2Fe4O9, leading to an increased Fenton degradation rate for oxytetracycline and H2O2 utilization rate.

Summary: Despite the development of alternative fuels and energy sources, the world still heavily relies on petroleum production and extraction. This poses a global challenge in treating oilfield produced water (OPW), as an average of 3 barrels of OPW is produced for every barrel of extracted oil. OPW contains various organic compounds, including recalcitrant naphthenic acids (NAs) that are not efficiently removed by conventional treatment methods. Advanced oxidation processes (AOPs), such as ozonation, photocatalysis, photochemical oxidation, and Fenton-based processes, are considered promising alternatives for degrading resistant organic compounds. This review focuses on discussing the treatment of OPW and the degradation of pollutants using different AOPs, addressing the influencing factors and strategies to enhance AOPs efficiency. The findings suggest that individual processes may have limitations, and current research is exploring the use of combined processes.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

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: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

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: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

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.
