Summary: This study investigated the coagulation performance and mechanisms of coral reef-like flocs formed in a continuous dosing coagulation (CDC) process for phosphorus removal in wastewater treatment. The CDC process exhibited enhanced phosphorus removal compared to conventional coagulation (CC) process, with a lower dosage required to meet the phosphorus discharge standard. The coral reef-like flocs formed in the CDC process had a stronger positive charge and larger specific surface area, which enhanced the absorption ability towards undissolved AlPO4 particles and dissolved phosphate anions.

Summary: This study discovered that the residual dissolved organic matter (DOM) can be effectively removed in the separation zone of the hybrid ozonation-coagulation (HOC) process through the in-situ formation of microbubble flocs mediated by the interaction between ozone and flocs. The researchers found that ozone can regulate the oxygen containing groups on the surface of flocs, which induces the formation of multilayer reaction sites. Hydrogen bonding to polar oxygen containing groups on microbubble flocs was identified as the dominant driver of DOM removal.

Summary: This study demonstrated that organics modified by ozonation can be captured in real time by micro-bubble flocs mediated by the interaction among ozone, Al species, and other organics using the hybrid ozonation-coagulation process. The real-time capture strategy during the HOC process can increase organics removal efficiency and broaden the ozone dosing range. The formation of Al-organic complexes with C-O-Al coordination bonds protects the modified organics from further oxidation by ozone.

Summary: This article studied the coagulation behavior of microplastics (MPs) that are difficult to remove during drinking water treatment. The results showed that both the size and concentration of MPs had a significant impact on coagulation, with size being the main factor. The type of MPs did not have a significant effect on coagulation. After optimization of operating conditions, the removal efficiency of MPs with a size ≥13 μm could reach over 70% using PAC and PAM. In the coagulation process, PAC played the most important role through electrical neutralization, while PAM's adsorption bridging and net sweeping assisted in coagulation.

Summary: In this study, a simple and eco-friendly method was developed for the removal of thiophene from gasoline using water-based silver nanoparticles. The silver nanoparticles were prepared using tannic acid as a reducing and stabilizing agent, and their adsorption efficiency was evaluated. It was found that silver nanoparticles of size 8.3 +/- 2 nm showed the highest adsorption efficiency (88.4%) for thiophene. The adsorption process followed a pseudo-second-order kinetics, and the mechanism involved the displacement of tannic acid by thiophene. This approach provides a new way to remove thiophene using aqueous silver nanoparticles.

Summary: A wet electrostatic precipitator (WESP) has a higher capture rate for PM2.5 than a dry type electrostatic precipitator. To utilize existing dust removal equipment and reduce smoke and dust emissions, a combination of chemical coagulation and humidification coagulation using WESP is proposed. The addition of chemical coagulant promotes coal-fired dust particle coagulation, while water vapor humidification enhances dust particle coagulation. The synergistic effect of coagulant and water vapor significantly improves the collection efficiency of WESP.

Summary: Reactive molecular dynamics (MD) was used to study the oxidation kinetics of silver nanoparticles (AgNPs) in the temperature range of 600-900 K. It was found that oxidation of metallic AgNPs led to the formation of a core-shell structure with a silver oxide layer on the surface. Higher temperatures and smaller particle sizes resulted in faster loss of the fcc crystallinity of the Ag core. The (100) facet was more prone to oxidation than the (111) facet, consistent with previous experiments and computational works. The fraction of Ag+ ions in the oxide layer increased with decreasing particle size, indicating that smaller particles released more Ag+ ions in water, in agreement with ion-selective electrode experiments. A reaction-limited model was used to quantify the oxidation rate of nanosilver at various temperatures, showing that higher temperatures led to faster oxidation. Additionally, smaller particles (d(p) ≤ 6 nm) exhibited lower activation energies, implying that they were more susceptible to oxidation than larger ones, consistent with experiments on Al nanoparticles.

Summary: Rapid urbanization has led to increased discharge of inorganic elements into the environment, but there is limited understanding about the fate and annual variations of multiple elements in wastewater treatment plants (WWTPs). To address this, wastewater and sludge samples from seven WWTPs in a southeast city of China were collected and analyzed. The results showed varying elemental concentrations in the influent, effluent, and sludge. The removal analysis revealed better removal of rare earth elements (REEs) compared to heavy metals. Activated sludge was found to be a major temporary storage site for elements, while excess sludge acted as the main sink for REEs. Significant spatial variations were observed among different WWTPs, while temporal variations were insignificant, indicating effective implementation of current environmental regulations.

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.
