Summary: The present study focused on the treatment of simulated chemical pharmaceutical wastewater using the Fenton oxidation process. The effects of operational parameters on the degradation efficiency of pollutants and biodegradability of the wastewater were investigated, and the results showed that the removal processes followed a second-order kinetic model. Quantum chemical analysis revealed a significant correlation between total energy and removal kinetic constant, indicating that higher total energy of organics made them more difficult to be removed. These findings are important for predicting the treatment efficiency of pollutants in real pharmaceutical wastewater.

Summary: A combination of graphene oxide quantum dots and peracetic acid (GQDs/PAA) was used to degrade sulfasalazine in municipal wastewater. The degradation efficiency of GQDs/PAA was evaluated under different reaction parameters and water matrices, achieving almost complete degradation in synthetic water and 80% degradation in municipal wastewater. The primary reactive radicals responsible for sulfasalazine degradation were identified as hydroxy (center dot OH) and peroxy radicals (CH3C(=O)OO center dot, CH3C(=O)O center dot). A degradation pathway was proposed based on the analysis of degradation intermediates. The genotoxic and mutagenic potential of the degradation products were assessed using the Ames test, which showed no mutagenicity. Furthermore, GQDs/PAA exhibited excellent disinfection capabilities, completely inactivating S. aureus and eliminating more than 90% of bacteria in raw municipal wastewater.

Summary: The widespread pharmaceutical pollutants in aquatic environment pose a threat to organisms and human health, and can be removed through the application of Advanced oxidation process (AOPs) using UV light, iron, and hydrogen peroxide. This study investigated the degradation kinetics, mineralization, and degradation products of mixed pollutants using AOP (UV/Fe2+/H2O2) method. Optimal conditions were found to be UV light 15 W, mixed pollutant 5 mg/L, Fe2+ 0.04 mM, H2O2 3 mM, and reaction time 10 min, resulting in over 99% degradation of mixed pollutants. The UV/Fe2+/H2O2 method also showed high performance in removing multiple pollutants in real wastewater.

Summary: Microscopy is an important step in microplastic analysis as it provides valuable information on count, size, color, and morphology. A method evaluation study involving multiple laboratories showed that recovery rates varied based on particle morphology and color, with fibers having the poorest recovery and clear/white particles having larger deviations. More experienced laboratories tended to report higher concentrations with higher variance among replicates. Training and improvements in color and morphology keys can enhance accuracy and precision of microscopy for microplastics.

Summary: Persistent organic pollutants (POPs) are a global concern, but information on their trends in water has been missing. Passive samplers have emerged as an attractive alternative for monitoring POPs. Deployments of passive samplers at globally distributed sites showed variations in POPs concentrations, with some compounds displaying higher concentrations in specific regions. These results contribute to our understanding of the global distribution and transport of organic pollutants in aquatic systems.

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.
