Summary: A hollow sphere (FeCo@C) is developed and shows high catalytic efficiency in the degradation of orange G (OG) using peroxymonosulfate (PMS). The FeCo alloy's (1 1 0) crystal plane is determined as the most active site for PMS activation. The generated reactive species (SO4 center dot-, (OH)-O-center dot, and O-1(2)) contribute to the catalytic performance. The synergistic effects between Fe and Co species are responsible for the high catalytic efficiency.

Summary: In this study, Cu-doped Mn3O4 was designed as a heterogeneous catalyst for the activation of peroxymonosulfate (PMS) under strongly alkaline conditions. Cu doping enhanced the catalytic activity of Cu1.5Mn1.5O4 towards SO52-, leading to the degradation of carbamazepine (CBZ) with the generation of SO4 center dot- radicals. The Cu1.5Mn1.5O4/PMS system exhibited sustained activity and stability, making it a promising system for alkaline pharmaceutical wastewater treatment.

Summary: This study investigates the enhancement of antibiotic degradation in water through material-enhanced peroxymonosulfate (PMS) activation. By partially substituting the B-sites of perovskite oxides, oxygen vacancies are introduced and catalytic activity is enhanced. Experimental results show that the adsorption capacity of perovskite oxides to PMS and the presence of oxygen vacancies have a synergistic effect on the degradation reaction.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

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.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
